Referring to fig. 1, an embodiment of an industrial internet of things system 1 of the present invention is suitable for collecting operation information of each sparepart 22 of each of a plurality ofmechanical devices 2, where the number of themechanical devices 2 may be a plurality as shown in fig. 1 or may be only 1; since the operation of eachmachine 2 is similar, only asingle machine 2 will be described in the following description.
For eachmachine 2, themachine 2 includes acontroller 21, and a plurality ofspare parts 22 electrically connected to thecontroller 21. In this embodiment, themachine tool 2 is a machine tool, thecontroller 21 has network communication capability, and the spare andaccessory part 22 may be a spindle, a fourth spindle, a cooler, an oil press, a tool magazine, a pump, or a cutter exhauster, but not limited thereto. It should be noted that, in other embodiments, themechanical device 2 may also include only onespare part 22, which is not limited to the disclosure of the present embodiment.
The industrial internet of things system 1 comprises aserver 11, auser end 12 in communication connection with theserver 11, and a plurality of data processing devices 13 respectively arranged on the spare andaccessory parts 22 of eachmechanical equipment 2; wherein theserver 11 stores a plurality of default operation rules in advance; theuser end 12 is a mobile device.
Each data processing device 13 corresponds to a network name and includes acommunication module 131, aprocessing module 132 electrically connected to thecommunication module 131, and a memory module 133 electrically connected to theprocessing module 132, where in this embodiment, the data processing device 13 is integrated into a single chip, but not limited to this. Thecommunication module 131 supports a wireless communication protocol (such as Wi-Fi (Wi-Fi) protocol or bluetooth (bluetooth) protocol), and is communicatively connected to theserver 11 and theue 12 through the wireless communication protocol, wherein the network name corresponding to each data processing apparatus 13 is related to the wireless communication protocol supported by the data processing apparatus; for example, if the wireless communication protocol supported by thecommunication module 131 is a wireless fidelity protocol, the network name corresponding to the data processing device 13 is a Service Set Identifier (SSID), and if the wireless communication protocol supported by thecommunication module 131 is a bluetooth transmission protocol, the network name corresponding to the data processing device 13 is a device name (device name).
The storage module 133 is configured to store an identification data and an operation rule set corresponding to thecomponent 22 set by the data processing device 13, where the identification data includes a device identification data corresponding to thecomponent 22 set by the data processing device 13, and a status data indicating an operation status of thecomponent 22 set by the data processing device 13.
Furthermore, when the data processing device 13 is first installed on the corresponding spare andaccessory part 22, the initial identification data and the operation rule set are written into the storage module 133; then, only when the operation rule set in the storage module 133 needs to be updated, theprocessing module 132 transmits a data request containing the device identification data corresponding to thecomponent 22 to theserver 11 through thecommunication module 131; then, after theserver 11 receives the data request, theserver 11 selects a target operation rule set from the default operation rules according to the device identification data in the data request, and transmits the target operation rule set to the data processing device 13; finally, the data processing device 13 receives the target operation rule set and stores it in the storage module 133 as the updated operation rule set. In the present embodiment, the device identification data includes, for example, manufacturer identification information (e.g., manufacturer name, manufacturer basic information, language system supported by manufacturer, etc.), product identification information (e.g., product name, product classification, product basic information, product version, etc.), and production serial number of theparts 22 set in the data processing device 13, but not limited thereto.
It should be noted that the data processing device 13 may further include at least one built-insensor 134, or themechanical apparatus 2 may also include at least onesensor 134 disposed on thespare part 22; thesensor 134 is used for sensing operation properties of thecomponent 22, wherein each operation property includes, for example, a temperature associated with thecomponent 22, a pressure associated with thecomponent 22, a vibration associated with thecomponent 22, or a current value associated with thecomponent 22.
For example, theserver 11 pre-establishes a database (not shown) containing a plurality of device identification data and a plurality of default operation rules associated with the device identification data, and theserver 11 can select the target operation rule set corresponding to each device identification data from the database of theserver 11 by interpreting the device identification data of each data request received by the server. Assuming that the spare andaccessory part 22 provided by the data processing device 13 is a spindle (not shown), a device identification data corresponding to the spindle includes a manufacturer identification information of the spindle, a product identification information of the spindle, and a product serial number of the spindle; wherein the manufacturer identification information, the product identification information, and the production serial number of the spindle indicate: various sensors (e.g., vibration sensor, temperature sensor, current sensor, not shown) required for sensing the operation properties of the spindle, and a set of target operation rules required for operating the spindle. When theserver 11 receives the data request, it first obtains the manufacturer identification information, the product identification information, and the production serial number of the spindle by interpreting the device identification data in the data request; then, theserver 11 selects the target operation rule set required for calculating the operation state of the spindle from the database of theserver 11 according to the manufacturer identification information, the product identification information and the production serial number, and stores the target operation rule set in the storage module 133 as the updated operation rule set.
Hereinafter, with reference to fig. 1, 2 and 3, it will be described in detail how the industrial internet of things system 1 collects operation information of thespare parts 22 provided by any one of the data processing devices 13.
In step S31, theprocessing module 132 of the data processing apparatus 13 generates status data indicating the operation status of thespare part 22 set by the data processing apparatus 13 according to the operation rule set in the storage module 133; furthermore, theprocessing module 132 can receive the sensing signal sensed by the at least onesensor 134 and generate the status data according to the sensing signal and the operation rule set in the storage module 133; theprocessing module 132 may also generate an operation result according to the sensing signal and the operation rule set in the storage module 133, and further generate the status data according to the operation result and the operation rule set in the storage module 133.
Continuing with the above example, assuming the spare andaccessory part 22 is the spindle (not shown), the set of operation rules in the memory module 133 may include, for example, "if a spindle temperature sensed by the temperature sensor (not shown) is greater than a temperature threshold value, generating a status data indicating that the spindle temperature is abnormal; otherwise, generating the status data indicating that the spindle temperature is normal, and outputting time domain data of the vibration sensor (not shown) through Fast Fourier Transform (FFT) to obtain an operation result; judging whether the operation result falls in a preset range or not; if so, generating the status data indicating that the vibration detection of the spindle is normal, otherwise, generating the status data indicating that the vibration detection of the spindle is abnormal, etc., but not limited thereto.
It should be noted that, theprocessing module 132 may also generate the status data only according to the set of operation rules stored in the storage module 133, for example, somespecific components 22 need to be maintained after being used for a predetermined time, and the data processing device 13 installed on aspecific component 22 starts to accumulate an operation time of thespecific component 22 after thespecific component 22 leaves the factory, where the set of operation rules includes the following conditional expressions: if the run time > the predetermined time, the status data indicating that theparticular part 22 is to be serviced is generated.
In step S32, theprocessing module 132 of the data processing apparatus 13 writes the status data generated in step S31 into the identification data stored in the storage module 133 to update the identification data.
In step S33, theprocessing module 132 of the data processing apparatus 13 sets the network name corresponding to the data processing apparatus 13 as the updated identification data described in step S32. Furthermore, if the wireless communication protocol supported by thecommunication module 131 is a wifi protocol, theprocessing module 132 sets the service setting identifier corresponding to the data processing apparatus 13 as the updated identification data; if the wireless communication protocol supported by thecommunication module 131 is bluetooth transmission protocol, theprocessing module 132 sets the device name corresponding to the data processing device 13 as the updated identification data.
In step S34, theprocessing module 132 of the data processing apparatus 13 broadcasts (broadcast) the network name set in step S33 through thecommunication module 131.
In step S35, theue 12 in the same communication range as the data processing apparatus 13 can receive the network name broadcasted by the data processing apparatus 13 in the scanning (scan) stage.
In step S36, theue 12 interprets the received network name to obtain the device identification data and the status data.
In step S37, theuser terminal 12 displays the operation status of thespare part 22 set by the data processing device 13 according to the device identification data and the status data interpreted in step S36.
In this embodiment, theuser terminal 12 installs an application program, and when the application program is executed, the steps S35 to S37 are performed and anoperation interface 4 shown in fig. 3 is presented. For example, theue 12 receives 4 network names in the scanning stage, and the application program decodes 4 device identification data and 4 status data from the network names, which correspond to the following 4 operation states of thespare parts 22 respectively: "A company's tool magazine A001 type, operational status: normal "," high pressure pump B01 type of company B, operating status: normal "," spindle type C001 of company C, operational status: warning ", and" D company vice D01 type, operating status: disable "; the application may present different operating states in blocks 41-43 of different colors, e.g., with ablock 41 of a first color indicating that the operating state is normal, ablock 42 of a second color indicating that the operating state is warning, and ablock 43 of a third color indicating that the operating state is disabled.
It should be noted that, although the present embodiment is described with asingle ue 12, in practical applications, the industrial internet of things system 1 often includes a plurality ofues 12, and anyue 12 located in the same communication range does not need to establish a one-to-one connection with each data processing device 13, so as to obtain the operation status of the spare andaccessory parts 22 set by the data processing device 13; instead, the network name corresponding to each data processing device 13 can be obtained in the scanning stage, and the operation state of thespare part 22 set by each data processing device 13 can be obtained according to the network name; in other words, theue 12 can acquire the operation status of all theparts 22 in the same communication range at the same time, so as to achieve many-to-many transmission, thereby greatly improving the efficiency and convenience of data acquisition.
After a user knows the operation state of the spare andaccessory parts 22 through theoperation interface 4 of theuser end 12, the user can further know the detailed operation information of one spare andaccessory part 22 through theoperation interface 4. For example, as shown in fig. 3, after the user finds that the operation status of the D01 type of the vise of the company D is "disabled", he can further know the detailed operation information of the vise D01 type by clicking acorresponding text 44 on theoperation interface 4 to establish a one-to-one connection between the data processing device 13 disposed on the vise D01 type and theuser terminal 12, and then theprocessing module 132 of the data processing device 13 transmits a data set related to the detailed operation information of the vise D01 type to theuser terminal 12 through thecommunication module 131 to enable theuser terminal 12 to present the data set, so that he can further know the reason why the "disabled" status of the vise D01 type occurs; wherein the data set includes the at least one sensing signal related to the D01 type of the vice, the status data, and the operation result. In this embodiment, the data set includes the at least one sensing signal, the status data, and the operation result, however, in other embodiments, the data set may also include at least one of the at least one sensing signal, the status data, and the operation result, which is not limited thereto.
It should be noted that, after theuser end 12 receives the data set related to thespare part 22 set by any one of the data processing devices 13, it can also transmit the data set to theserver 11; in addition, each data processing device 13 may also directly transmit the data set to theserver 11; alternatively, each data processing device 13 may transmit the data set to thecontroller 21, and then thecontroller 21 transmits the received data set to theserver 11. Therefore, theserver 11 can collect the operation information of each spare andaccessory part 22, which is not only helpful for predicting and eliminating faults in the processing process, but also can analyze big data of the collected operation information in the future and be applied to an automatic production line or an unmanned intelligent factory.
In summary, the industrial internet of things system 1 of the present invention is suitable for collecting the operation information of eachpart 22 of eachmechanical device 2, and has the following effects: thefirst user end 12 located in the same communication range can obtain the network name corresponding to each data processing device 13 in the scanning stage, and the operating state of the spare andaccessory part 22 arranged in the network name can be obtained, so that the transmission of many-to-many data in the same time is achieved, and the efficiency and convenience of data acquisition are greatly improved; secondly, the user can check the operation state of the spare andaccessory parts 22 set by each data processing device 13 in real time through theuser end 12, so that when any one of themechanical equipment 2 is abnormal, the user can clearly know which spare andaccessory part 22 in themechanical equipment 2 has a problem, thereby avoiding time cost misplacement and human resource waste; third, theserver 11 can collect the operation information of thespare parts 22 through each data processing device 13 for the analysis and processing of the subsequent data, so the purpose of the present invention can be achieved.
The foregoing is merely illustrative of the present invention and is not intended to limit the scope of the invention, which is defined by the appended claims and their equivalents.
