Additional features and advantages of the invention will be set forth in the detailed description which follows.
Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
In addition, the "connection" referred to in the embodiments of the present invention may be a wired connection or a wireless connection.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a schematic structural diagram of a tire anti-theft system according to an embodiment of the present invention, which is implemented in a scenario including, but not limited to, a vehicle, and the following is only an example of the vehicle. In addition, the functionality of the tire anti-theft system is not limited to tire anti-theft, but may be used to assist a user in scheduling a trip, for example.
As shown in fig. 1, a tire theft prevention system according to an embodiment of the present invention may include: the tirepressure monitoring device 100 is installed on a vehicle tire, communicates with theuser terminal 200, is in a sleep mode after the vehicle is shut down, and is used for responding to any one of a trigger instruction from theuser terminal 200, detected tire abnormal vibration information and user operation, activating to enter a working mode, and acquiring tire pressure information of the corresponding tire in the working mode; theuser terminal 200 is configured to send the trigger instruction to the tirepressure monitoring device 100, acquire tire pressure information acquired by the tirepressure monitoring device 100 to analyze whether the tire pressure is normal, generate an early warning instruction for controlling an action of the vehicle-mounteddevice 300 when the tire pressure is analyzed to be abnormal, and send the early warning instruction to the tirepressure monitoring device 100; and the vehicle-mounteddevice 300 for receiving the early warning instruction from the tirepressure monitoring apparatus 100 through a vehicle CAN bus, and performing an alarm, an environmental condition recording, and/or a tire locking in response to the early warning instruction.
Each tire of the vehicle is provided with a tire pressure monitoring device, and the tire pressure monitoring device is awakened to enter a working mode according to three triggering conditions (namely a triggering instruction, abnormal tire vibration information and user operation, which will be described in detail later). In the working mode, the tire pressure monitoring device can collect tire pressure information in real time and send the tire pressure information to the user terminal so that the user terminal can analyze the tire pressure. Here, the user terminal mainly refers to an APP (Application) configured on the terminal, and the APP can perform data processing such as instruction generation, information transmission and reception, tire pressure analysis and the like, wherein the APP can obtain a result of whether the tire pressure is normal through a preset algorithm, display the result to a user, and simultaneously start the vehicle-mounted device to execute an early warning instruction to assist in theft prevention.
Fig. 2 is a schematic structural view of the tire airpressure monitoring device 100 in the embodiment of the present invention. As shown in fig. 2, the tirepressure monitoring device 100 may include: a gaspressure transmitter module 110 for detecting tire pressure information in an operation mode of the tire pressure monitoring device; afirst communication module 120, configured to implement wifi or mobile cellular network-based communication between the tirepressure monitoring device 100 and theuser terminal 200; theacceleration sensor module 130 keeps running in both the working mode and the dormant mode of the tire pressure monitoring device, and is used for sensing the tire and the vibration around the tire and generating abnormal vibration information of the tire; and abattery module 140 connected to a vehicle power module of the vehicle for supplying power to the tire pressure monitoring device and for supplying power to the vehicle power module after the vehicle is started.
The gaspressure transmitter module 110 is a common tire pressure monitoring device, and is not described herein again. The sleep mode of the tirepressure monitoring device 100 mainly means that the gaspressure transmitter module 110 is in sleep. Specifically, when the vehicle is in a flameout state, the tirepressure monitoring device 100 is in a sleep mode, for example, the standby state of the device is maintained at an ultra-low current of 0.6mA, so that the waste of the battery power and the communication cost can be reduced as much as possible, and the utilization rate of the tirepressure monitoring device 100 is improved.
Thefirst communication module 120 enables wifi or mobile cellular network based communication between the tirepressure monitoring device 100 and theuser terminal 200. In other embodiments of the present invention, communication between the tirepressure monitoring device 100 and theuser terminal 200 may also be made based on bluetooth. However, the transmission distance of bluetooth is short, so that the user terminal cannot remotely master the tire pressure information, and the stability of bluetooth transmission has a great relationship with obstacles, so that the situation that information is not sent timely exists. Therefore, the communication mode based on wifi or mobile cellular network compares in bluetooth mode, more can guarantee that tire pressure information can accurately convey to the car owner in real time.
Theacceleration sensor module 130 does not enter the sleep mode with the tirepressure monitoring device 100 because theacceleration sensor module 130 needs to sense the tire and the vibration around the tire in real time to determine whether to wake up the tirepressure monitoring device 100. For example, after the vehicle is shut down, the tire vibrates, which largely represents tire abnormality, i.e. tire failure and theft. Therefore, when theacceleration sensor module 130 senses abnormal vibration, the tirepressure monitoring device 100 is actively awakened, and theft can be prevented to a great extent.
In a preferred embodiment, theacceleration sensor module 130 is further configured to send a command for performing environmental condition recording to the vehicle-mounted device when the tire abnormal vibration information is generated, and send the command for performing environmental condition recording to the vehicle-mounteddevice 300 through a vehicle CAN bus. That is, when waking up the tirepressure monitoring device 100, theacceleration sensor module 130 also wakes up the vehicle-mounteddevice 300 to record the environmental condition, for example, to take a video shot, so that the user can conveniently check the environmental condition record subsequently to assist in retrieving the stolen tire.
Thebattery module 140 mainly supplies power to the tirepressure monitoring device 100 when the tirepressure monitoring device 100 is in the operating mode, but may supply power to the vehicle power module to support charging after the vehicle is started when the vehicle is started under the condition of large electric quantity. The vehicle power module is, for example, a motor drive.
Fig. 3 is a schematic structural diagram of a user terminal in an embodiment of the present invention, where the user terminal may refer to an APP installed on a terminal such as a smart phone, a notebook computer, a tablet computer, and a wearable device, and hereinafter, a mobile phone APP is mainly taken as an example. As shown in fig. 3, theuser terminal 200 may include: a receivingmodule 210 for receiving the tire pressure information from the tirepressure monitoring device 100; theanalysis module 220 is configured to analyze the tire pressure information to determine whether the tire pressure is normal, and generate the early warning instruction when the tire pressure is determined to be abnormal; and a sendingmodule 230, configured to generate and send the trigger instruction to the tirepressure monitoring device 100 in response to a user operation, and further configured to send the warning instruction to the vehicle-mounteddevice 300.
The receivingmodule 210 and the sendingmodule 230 are common functional modules in the smart phone APP, and are not described herein again. For theanalysis module 220, the process of determining whether the tire pressure is normal may be: firstly, judging whether the tire pressure is zero or not, and activating vehicle-mounted equipment to give an alarm if the tire pressure is zero; if the tire pressure changes greatly in a short time, for example, when the vehicle is stationary, if the pressure difference value of the tire pressure is more than or equal to 0.5 within half an hour, the pressure difference value is displayed through a mobile phone APP terminal, and the abnormality of the tire pressure of the vehicle owner is timely reminded to arouse the attention of the vehicle owner; and if the pressure difference value of the tire pressure continuously drops within half an hour and the pressure difference value is more than or equal to 1, activating vehicle-mounted equipment to alarm, record environmental conditions and/or lock the tire. The reminding mode of the APP end of the mobile phone comprises a page mode, a sound mode or a vibration mode.
Fig. 4 is a schematic configuration diagram of the in-vehicle apparatus of the embodiment of the invention. As shown in fig. 4, the in-vehicle apparatus 300 includes any one or more of: analarm system 310, configured to alarm in response to the early warning instruction; the vehicle-mountedcamera 320 is used for responding to the early warning instruction to shoot and record the environmental conditions around the vehicle; and a self-lockingdevice 330 provided at each tire for performing an action of automatically locking the tire in response to the early warning command.
Thealarm system 310 may be a conventional vehicle alarm system, and requires audible and visual alarm.
Among them, the in-vehicle camera 320 mainly performs environmental condition recording, and is preferably installed under two exterior rear view mirrors of the vehicle to maximally photograph the surrounding environment of the vehicle.
After the self-lockingdevice 330 receives the early warning instruction, the self-locking device executes the action of automatically locking the tire, so that the tire is prevented from being stolen to a greater extent, and the property loss of a vehicle owner is better protected.
In a preferred embodiment, a second communication module may be disposed in thealarm system 310, the vehicle-mountedcamera 320 and the self-lockingdevice 330. Taking the self-lockingdevice 330 as an example, the self-locking device may include asecond communication module 331, configured to implement communication between the vehicle-mounteddevice 300 and theuser terminal 200, so that the vehicle-mounteddevice 300 receives the warning instruction from theuser terminal 200 through thesecond communication module 331. Therefore, the vehicle-mounteddevice 300 can directly obtain the early warning instruction without being forwarded by the tirepressure monitoring device 100, and the response efficiency of the vehicle-mounted device is improved. However, because the tire pressure monitoring device and the vehicle-mounted device on the vehicle CAN communicate through the vehicle CAN bus, and the tire pressure monitoring device must be capable of communicating with the user terminal, the size and cost of the vehicle-mounted device are prevented from being increased by assembling the second communication module in the vehicle-mounted device in a manner that the tire pressure monitoring device forwards the warning instruction to the vehicle-mounted device.
Additionally, with continued reference to fig. 4, aprocessing unit 332 and alocking mechanism 333 may also be included in the self-lockingdevice 330. Thelock mechanism 333 is a mechanical structure for locking the tire, and theprocessing unit 332 can control the operation of thelock mechanism 333 by processing an alarm command or the like. Similarly, processing units for processing information may also be configured in thealarm system 310 and the vehicle-mountedcamera 320, and details thereof are not repeated here.
It should be noted that the connection line relationship between the modules shown in fig. 1 to fig. 4 is exemplary, and does not limit the scope of the embodiments of the present invention, and those skilled in the art can make reasonable adjustments according to actual situations.
Further, the embodiment of the present invention refers to the tirepressure monitoring device 100 being awakened to enter the operating mode according to the three triggering conditions, i.e., the triggering instruction, the tire abnormal vibration information, and the user operation. Fig. 5 is a triggering flowchart of the tire pressure monitoring device. With reference to fig. 5, when an owner wants to actively check the tire pressure condition, a trigger instruction may be sent to the first communication module of the tire pressure monitoring device through the mobile phone APP, and when the tire pressure monitoring device receives the trigger instruction, the tire pressure monitoring device is directly triggered and activated, so that the tire pressure monitoring device is changed from the sleep mode to the working mode; when the acceleration sensor module of the tire pressure monitoring device senses abnormal vibration of the tire, the tire is indicated to be abnormal to a great extent, so that the tire pressure monitoring device is actively activated to be changed from a dormant mode to a working mode; when the owner of the automobile thinks that the possibility of tire problems or theft is high in a certain road section or a certain time period, the owner of the automobile can manually activate the tire pressure monitoring device to change the tire pressure monitoring device from the dormant mode to the working mode.
Therefore, it can be understood that the above three triggering conditions correspond to three application scenarios of the tire anti-theft system according to the embodiment of the present invention, and the three application scenarios will be specifically described below by way of example. In an example, the user terminal corresponds to a mobile phone APP, and the vehicle-mounted device mainly relates to a vehicle-mounted camera and an alarm system.
Mobile phone APP active triggering tire pressure monitoring device
Fig. 6 is a triggering flow chart of actively triggering the tire pressure monitoring device through the mobile phone APP in the embodiment of the present invention. As shown in fig. 6, the triggering process mainly includes: the mobile phone APP is required to be kept in an open state, when a vehicle owner actively triggers a relevant button of the mobile phone APP, for example, a [ check tire pressure ] command of a mobile phone APP terminal is triggered, and the command is a trigger instruction; the triggering instruction is sent to a first communication module of the tire pressure monitoring device through a wifi signal or a mobile cellular network, and when the triggering instruction is received by the module, the module directly wakes up the tire pressure monitoring device to enable the tire pressure monitoring device to be changed from a dormant mode to a working mode; in the working mode, tire pressure information can be monitored in real time and packaged and sent to the APP end of the mobile phone; cell-phone APP analysis tire pressure is normal, if then record the tire pressure normal, otherwise give the warning.
Under this application scene, the car owner can long-rangely look over the tire pressure information, and cell-phone APP is in normal range through predetermineeing the algorithm check out the tire pressure, if abnormal, can give the warning. Accordingly, the vehicle owner can know the condition of the tire in advance so as to arrange the journey.
Secondly, the acceleration sensor module actively triggers the tire pressure monitoring device
Fig. 7 is a triggering flow chart of the acceleration sensor module actively triggering the tire pressure monitoring device in the embodiment of the present invention. As shown in fig. 7, the triggering process mainly includes: after the acceleration sensor module senses vibration, the tire pressure monitoring device and the vehicle-mounted cameras on the two sides of the vehicle are automatically activated; the vehicle-mounted camera automatically records the environmental conditions at two sides of the vehicle, records 20-second videos and stores the videos, so that the vehicle owner can conveniently give an alarm in the later period or check related recording conditions to help the vehicle owner to better recover the loss; after the activation of the tire pressure monitoring device, the tire pressure information is packaged and transmitted to the mobile phone APP, and at the moment, the mobile phone APP performs calculation on whether the tire pressure is normal or not according to the transmitted tire pressure value. The specific calculation method may be: firstly, judging whether the tire pressure is zero, and if the tire pressure is zero, activating an alarm system; if the tire pressure changes greatly in a short time, for example, when the vehicle is stationary, if the pressure difference value of the tire pressure is more than or equal to 0.5 within half an hour, displaying through the APP terminal of the mobile phone to remind a vehicle owner that the tire pressure is abnormal; if the pressure difference value of the tire pressure continuously drops within half an hour and the pressure difference value is more than or equal to 1, activating an alarm system.
The vehicle-mounted camera is particularly important in the application scene, so that the configurable vehicle-mounted camera comprises an HDR high-light-sensitivity technology, and a clear picture can be still shot under dark light.
Through the process, when there is the vibrations in the vehicle tire and feels, the vehicle can initiatively send tire pressure information to car owner's cell-phone APP to let the car owner understand the tire condition better, more quickly more efficiently supplementary vehicle understand the tire condition, and can provide strong evidence for the later stage is pursued through the video recording.
Thirdly, triggering the tire pressure monitoring device through user operation
The application scenario mainly addresses the cases such as: the owner of the vehicle recognizes that the tire is in a problem or stolen in the road section or the time period, for example, the surrounding road section where a child plays and sticks the tire or the time period when other people are predicted to maliciously report and damage the tire can be obtained, the tire pressure can be monitored, and the alarm system and the vehicle-mounted camera are started. Therefore, for the application scenario, the tire pressure monitoring device can be started by adopting a manual triggering mode after the tire pressure monitoring device is directly parked without transmitting a signal through the acceleration sensor module, for example, a start button of the tire pressure monitoring device is pressed.
Fig. 8 is a triggering flowchart for triggering the tire pressure monitoring device through user operation in the embodiment of the present invention. As shown in fig. 8, the triggering process mainly includes: after the tire pressure monitoring device is manually started, the tire pressure monitoring device is always in a working mode; the tire pressure monitoring device can pack tire pressure information at regular time after being started and send the tire pressure information to the mobile phone APP through the first communication module, the mobile phone APP analyzes the tire pressure information, whether the tire pressure belongs to a normal category is checked according to a preset algorithm, if the tire pressure belongs to the normal category, a result is directly returned to the tire pressure monitoring device, and the device continues to monitor and send the tire pressure information; if the abnormal condition exists, the result can be fed back to the tire pressure monitoring device, and the device can activate the alarm system and the vehicle-mounted camera in an in-vehicle communication mode.
The vehicle-mounted camera can be set as default shooting or can be changed into recording of the surrounding environment. This setting can be set for according to car owner's actual demand at cell-phone APP end. The problem of the application scene can be well solved through the triggering process, an automobile owner can know the tire pressure condition in a special scene at the first time, and beneficial measures are taken to reduce the loss to the minimum.
In conclusion, the tire anti-theft system provided by the embodiment of the invention can ensure that an owner can effectively know the tire pressure condition of the vehicle in time in various scenes, so that the automobile anti-theft system can make full preparations for traveling and know whether the vehicle has a theft risk or not in real time. Meanwhile, when the vehicle has the risk of tire theft, the vehicle can automatically start the tire pressure monitoring function, and the vehicle owner is informed, and meanwhile, video recording is carried out, so that the vehicle owner can find out the party possibly damaging the vehicle, and the safety and the rights and interests of the vehicle owner are better guaranteed.
Fig. 9 is a schematic flow chart of a tire theft prevention method according to an embodiment of the present invention, which is applied to a vehicle and adopts the same inventive concept as the tire theft prevention system described above.
As shown in fig. 9, the tire theft prevention method may include the steps of:
step S110, establishing communication between the tire pressure monitoring device installed on the vehicle tire and the user terminal based on wifi or a mobile cellular network.
The tire pressure monitoring device may be a tire pressure monitoring device in the tire anti-theft system, and a first communication module may be built in the tire pressure monitoring device to realize communication with a user terminal based on wifi or a mobile cellular network. In addition, the user terminal is, as mentioned above, for example, a mobile phone APP.
Step S120, in response to any one of a trigger instruction from the user terminal, abnormal vibration information of a tire detected by a vehicle, and user operation, activating the tire pressure monitoring device to enter a working mode, and enabling the tire pressure monitoring device to acquire tire pressure information of a corresponding tire in the working mode.
Specifically, the user terminal may send a trigger instruction to the tire pressure monitoring device to activate the tire pressure monitoring device that is in the sleep mode after the vehicle is turned off. However, in addition to the triggering command, the tire pressure monitoring device may be awakened to enter the operating mode through abnormal vibration information detected by its own acceleration sensor module or manual operation of a user. The tire pressure monitoring device in the working mode can detect the tire pressure information in real time and carry out packaging and sending.
In addition, for the case where the vehicle detects the abnormal vibration information of the tire, the tire theft preventing method may further include: and sending a command for recording the environmental condition to the vehicle-mounted equipment while activating the tire pressure monitoring device. For example, the acceleration sensor module wakes up the tire pressure monitoring device when detecting abnormal vibration information, and wakes up the vehicle-mounted camera together to perform video shooting to record the environmental condition.
Step S130, transmitting the tire pressure information to the user terminal.
Specifically, the tire pressure monitoring device transmits the tire pressure information to the user terminal through the first communication module thereof, and the tire pressure information may be transmitted in real time or at predetermined time intervals.
And step S140, receiving an early warning instruction which is generated when the user terminal analyzes that the tire pressure is abnormal and is used for controlling the action of the vehicle-mounted equipment.
Specifically, the user terminal can process the tire pressure information through a preset algorithm to analyze whether the tire pressure is abnormal or not, generate an early warning instruction for controlling the action of the vehicle-mounted equipment when the tire pressure is abnormal, and then issue the early warning instruction to the vehicle end based on wifi or a mobile cellular network.
And S150, forwarding the early warning instruction to the vehicle-mounted equipment through a vehicle CAN bus so that the vehicle-mounted equipment responds to the early warning instruction to execute alarming, environmental condition recording and/or tire locking.
Specifically, the user terminal CAN issue the early warning instruction to the tire pressure monitoring device, and the tire pressure monitoring device forwards the early warning instruction to the vehicle-mounted equipment by using the vehicle CAN bus, so that a communication module specially communicating with the user terminal CAN be prevented from being configured in the vehicle-mounted equipment (such as a vehicle-mounted camera).
Another embodiment of the present invention also provides a machine-readable storage medium having stored thereon instructions for causing a tire pressure monitoring device to execute the above-mentioned tire anti-theft method applied at a vehicle end.
It should be noted that, for details of the tire anti-theft method applied to the vehicle end, reference may be made to the above-mentioned embodiments related to the tire anti-theft system, and details are not described herein again.
Fig. 10 is a flowchart illustrating another tire theft prevention method according to an embodiment of the present invention, which is applied to a user terminal and adopts the same inventive concept as the tire theft prevention system described above. As shown in fig. 10, the tire theft prevention method may include:
step S210, establishing communication between the tire pressure monitoring device installed on the vehicle tire and the user terminal based on wifi or a mobile cellular network.
Referring to the above step S110, the communication between the tire pressure monitoring device and the user terminal may be achieved by configuring the first communication module in the tire pressure monitoring device. It should be noted that the user terminal also needs to be configured to have a function capable of communication based on wifi or a mobile cellular network.
Step S220, a triggering instruction is sent to the tire pressure monitoring device.
For example, when a user wants to actively check tire pressure information, a trigger instruction may be sent to the tire pressure monitoring device by pressing or touching a corresponding function key of the mobile phone APP, so as to wake up the tire pressure monitoring device that may be in a dormant state.
Step S230, obtaining tire pressure information of the corresponding tire collected by the tire pressure monitoring device in a working mode in response to any one of the triggering instruction, the tire abnormal vibration information and the user operation being activated.
Specifically, the tire pressure monitoring device is awakened to enter a working mode under three triggering conditions, starts to acquire tire pressure information in real time, and sends the tire pressure information to the user terminal in real time or at preset time intervals.
And step S240, analyzing whether the tire pressure is normal or not according to the tire pressure information, and generating an early warning instruction for controlling the action of the vehicle-mounted equipment when the tire pressure is analyzed to be abnormal.
Specifically, the user terminal may analyze whether the tire pressure is normal through a preset algorithm, and generate an early warning instruction based on the abnormal tire pressure. The tire pressure analysis process is, for example: firstly, judging whether the tire pressure is zero, and if the tire pressure is zero, judging that the tire pressure is abnormal; if the tire pressure has large change in a short time, for example, when the vehicle is stationary, if the pressure difference value of the tire pressure is more than or equal to 0.5 within half an hour, the tire pressure is judged to be abnormal; if the pressure difference value of the tire pressure continues to decrease within half an hour and the pressure difference value is more than or equal to 1, the tire pressure is judged to be abnormal.
In addition, for the abnormal condition of tire pressure, the user terminal can remind the vehicle owner through the form of page, sound or vibration.
And step S250, sending the early warning instruction to the vehicle so that the vehicle-mounted equipment can respond to the early warning instruction to execute alarming, environmental condition recording and/or tire locking.
Preferably, the sending of the warning instruction to the vehicle may include two types: 1) sending the early warning instruction to the tire pressure monitoring device so that the vehicle-mounted equipment receives the early warning instruction from the tire pressure monitoring device through a vehicle CAN bus; or 2) directly sending the early warning instruction to the vehicle-mounted equipment.
The mode 1) is characterized in that a vehicle CAN bus is utilized, so that early warning instruction forwarding is realized in an in-vehicle communication mode, and vehicle-mounted equipment CAN be directly applied to vehicle-mounted cameras and the like which are not provided with a special communication module in the current market; in the mode 2), a communication module capable of communicating with the user terminal needs to be configured for the vehicle-mounted device, so that the vehicle-mounted device can directly receive the expected instruction, and the instruction sending process is simplified.
Another embodiment of the present invention may also provide a machine-readable storage medium having stored thereon instructions for causing a user terminal to execute the above-mentioned tire anti-theft method applied to the user terminal.
It should be noted that, for details of the tire anti-theft method applied to the user terminal, reference may be made to the above-mentioned embodiments related to the tire anti-theft system, and details are not repeated herein.
