As shown in fig. 2, the system architecture may include a cabinet and a robot. Tens of computers are deployed in each cabinet, and hundreds of cabinets are deployed in each machine room. The robot is a movable inspection robot, and the chassis of the robot is provided with wheels or caterpillar tracks.
The cabinet arrays in the data machine room are orderly arranged, and each cabinet array consists of a plurality of cabinets. When the inspection robot works in the machine room, a global map in the machine room is established by means of a self navigation system, and inspection points (xn, yn) are arranged on each machine cabinet. When the cabinet (x 2, y 1) triggers a door opening event, the inspection robot can reach the cabinet position according to the coordinate points (x 2, y 1) to execute a monitoring task.
And wireless communication modules are respectively installed on the cabinet and the robot, so that information interaction can be performed. The robot of the present application supports two modes of start. One way is triggered by the cabinet, and when the cabinet detects that the cabinet door is opened, cabinet door opening information including cabinet identification is sent through the wireless communication module. The robot determines the monitoring position according to the cabinet identification, and then shoots before traveling to the cabinet. The other mode is triggered by a worker, and the worker entering the machine room can instruct a robot to follow the worker to run in the machine room by means of code scanning and the like. After the cabinet door is opened by the staff, the robot starts to shoot the operation process of the staff.
The specific operation of the robot is shown in steps 401-404. The specific operation of the cabinet is shown in steps 501-502.
The bottom of the cabinet is provided with a proximity sensor. The proximity sensor is triggered to output a low level when the cabinet door is closed and a high level when the cabinet door is open. According to the output level of the proximity sensor, the opening and closing states of the cabinet door of the data machine can be judged.
It should be understood that the number of cabinets and robots in fig. 2 is merely illustrative. There may be any number of cabinets and robots, as desired for implementation.
Fig. 3 is a schematic circuit diagram of a system for monitoring the state of a cabinet, which is composed of a cabinet end device a and a robot end device B. The device A mainly comprises a proximity sensor, a controller, a wireless communication module, an antenna, a data storage module and a real-time clock. The proximity sensor detects the state of the cabinet door, the data storage module stores cabinet identification (code), the door opening and closing event can also be stored in the data storage module for log inquiry, the real-time clock provides current time for the controller, and the wireless communication module and the antenna enable the device A to have the remote communication capability with the robot body. The robot end device B consists of a controller, a wireless communication module, an antenna, a power system, a navigation system and a monitoring camera. The power system can enable the robot to freely move, the navigation system provides a position location and a global map for the robot, the monitoring camera can enable the robot to shoot images to achieve a monitoring function, and the wireless communication module and the antenna are used for remotely communicating with the device A at the cabinet end.
With continued reference to fig. 4, a flow 400 of one embodiment of a method for monitoring cabinet status according to the present disclosure applied to a robot is shown. The method for monitoring the state of the cabinet comprises the following steps:
step 401, receiving cabinet door opening information including a cabinet identifier sent by a cabinet.
In this embodiment, an execution body (e.g., a robot shown in fig. 2) of the method for monitoring a cabinet status may receive cabinet door opening information sent by a cabinet through a wireless communication module. Wherein the cabinet door opening information may include a cabinet identification. When the state of the cabinet door changes, the device A at the cabinet end reports a trigger event to the robot in a wireless communication mode. The cabinet door opening information format can be pre-defined, 1bit is used for representing the opening or closing state of the door, and the length of the cabinet identification is related to the number of cabinets in the machine room.
Step 402, inquiring the monitoring position of the cabinet according to the cabinet identification.
In this embodiment, the robot pre-stores the monitoring location of each cabinet in the machine room. And the monitoring position of the cabinet can be queried according to the cabinet identification. The monitoring position refers to a position where the robot is at when shooting, and is usually at a position where the cabinet is not easily covered by a worker, such as left front or right front of the cabinet. The monitoring position may also be pre-agreed, for example, requiring the operator to be in front of the left of the cabinet when operating, and then set the monitoring position to the front right of the cabinet.
And step 403, driving to the monitoring position to shoot the interior of the cabinet.
In this embodiment, the robot travels to the monitoring location at the guidance of the navigation system. And starting the monitoring camera at the monitoring position to shoot. The monitoring camera can rotate up and down and left and right, and shoot from any angle.
Alternatively, the robot can recognize (pre-train out the neural network model) from the captured image whether the worker blocks the cabinet. If occlusion is detected, the worker may be prompted by voice to adjust the position at which he is standing. Or the robot adjusts the position of the robot to adapt to the position of the staff. If the robot has a telescopic monitoring probe, the robot can bypass a worker to shoot. The number of the monitoring cameras may be plural, and photographing from multiple angles may be performed by bypassing the worker like an antenna.
If the robot detects that the cabinet is always blocked by a worker and cannot normally shoot, alarm information can be sent to the server to prompt suspicious conditions.
And step 404, in response to receiving cabinet door closing information including cabinet identification sent by the cabinet, stopping shooting the interior of the cabinet, and storing the image record.
In this embodiment, the proximity sensor can detect that the cabinet door is closed and then generate cabinet door closure information including the cabinet identification, similar to when the door is opened. And sending the cabinet door closing information to the robot through the wireless communication module. The robot receives cabinet door closing information including cabinet identification through the wireless communication module. And matching the cabinet identification in the cabinet door closing information with the cabinet identification of the cabinet door opening information, so that the cabinet door closing information can be determined to be specific to the robot. Without mistaking cabinet door closing information sent to another robot as cabinet door closing information of a cabinet currently being photographed. And stopping shooting the interior of the cabinet after determining that the cabinet door closing information of the cabinet currently being shot is received, and storing the image record.
In some optional implementations of this embodiment, the cabinet door opening information further includes an opening time, the cabinet door closing information further includes a closing time, and the method further includes storing the cabinet identification, the opening time, the closing time, and the image record in a monitor record table. The cabinet can obtain time through a timing clock, and then the opening time is added when the cabinet door opening information is generated. And adding closing time when the cabinet door closing information is generated.
Alternatively, if the cabinet has no real-time clock, the time when the robot receives the cabinet door opening information may be taken as the opening time, and this time is different from the time when the robot actually starts shooting, because the robot needs to take time to reach the monitoring position. Similarly, the time when the robot receives the cabinet door closing information can be used as closing time.
For example, as shown in fig. 6b, the reported information is composed of 6 bytes, and the cabinet door status occupies 1 bit (0 indicates that the door is closed, 1 indicates that the door is opened), the cabinet code occupies 15 bits (the unique code of 32768 cabinets in the same machine room can be realized), and the real-time occupies 32 bits (the specific time of 5 bits in year, 4 bits in month, 5 bits in day, 6 bits in time, 6 bits in minutes, and 6 bits in second).
As shown in fig. 6c, the cabinet identifier, the opening time, the closing time and the image record are stored in a monitoring record table.
In some optional implementations of this embodiment, the method further includes uploading the captured image to a server in real time and/or the monitoring record. And finally, the robot outputs an initial event of each cabinet door opening and closing event and image records during door opening operation to the server, so that the operation inside the cabinet is monitored in all directions. The robot can upload the monitoring video to the server in real time, or upload the monitoring video to the server after shooting is finished.
In some optional implementations of the present embodiments, the method further includes, in response to receiving cabinet door opening information including cabinet identifications sent by at least 2 cabinets, querying a data value of each cabinet according to the cabinet identifications, and shooting while traveling to a monitoring location of a cabinet with a highest data value. The staff may open the doors of multiple cabinets, and the robot cannot take into account each cabinet, at which time the cabinets need to be prioritized. Taking the cabinet with the highest priority as a shooting target. The value of the data stored in the computers of the racks can be evaluated at the time of data storage, i.e., the greater the loss of the company if the data is stolen, the higher the value of the description data. In order to ensure the information security of the cabinet with the highest data value, the cabinet is monitored preferentially. If the door of the cabinet with the highest data value is closed, the robot can select the cabinet with the highest data value from other cabinets which are not monitored as a shooting target, and the robot can drive to a monitoring position of the shooting target for shooting.
Alternatively, if there are multiple robots that can be scheduled, the robots are allocated according to their distance from the cabinet. The robot selects the cabinet closest to the robot and with the cabinet door opened to shoot.
In some optional implementation manners of the embodiment, the method further includes querying hardware values in the cabinets with the highest data values if the number of cabinets with the highest data values is a plurality of cabinets, and driving to a monitoring position of the cabinet with the highest hardware value to shoot. If there are a plurality of cabinets with the same data value, the cabinet with the highest hardware value is selected for monitoring. The hardware value refers to the market price of the hardware device. If the door of the cabinet with the highest hardware value is closed, the robot can select the cabinet with the highest data value from other cabinets which are not monitored as a shooting target, and the robot can drive to a monitoring position of the shooting target for shooting. Namely, the data value is firstly ordered, and then the hardware value is ordered. The cabinet with the highest hardware value is selected under the condition of the highest data value.
In some optional implementations of the present embodiments, the method further includes following the user in response to receiving a follow-up command input by the user, photographing an interior of a target cabinet in response to receiving cabinet door opening information including a cabinet identifier sent by the target cabinet, stopping photographing the interior of the target cabinet in response to receiving cabinet door closing information sent by the target cabinet, and saving an image record. The user can input a follow-up shooting instruction through a two-dimensional code on the scanning robot, and can read the work card information of the user through a card reader on the robot, and the user can follow the user to run after the identity of the user is identified. After the user opens the door, the cabinet door will send the door opening information to the robot, which starts executing steps 401-404.
With continued reference to fig. 5, a flow 500 of one embodiment of a method for monitoring a state of a cabinet according to the present disclosure is shown applied to the cabinet. The method for monitoring the state of the cabinet comprises the following steps:

The proximity sensor is triggered to output a low level when the cabinet door is closed and a high level when the cabinet door is open. According to the output level of the proximity sensor, the opening and closing states of the cabinet door of the data machine can be judged. And after the proximity sensor detects that the cabinet door is opened, notifying the controller. The controller obtains the cabinet identification from the data storage module, and then generates cabinet door opening information (the first 16 bits, 1 st bit, is 1 as shown in fig. 6 b) according to the opening state and the cabinet identification. And then the cabinet door opening information is sent to the robot through the wireless communication module. The robot performs steps 401-403 after receiving the cabinet door opening information.
In response to detecting the enclosure door closing, the enclosure door closing information including the enclosure identification is sent to the robot, step 502.
In this embodiment, a proximity sensor is mounted at the bottom of an execution body (e.g., the cabinet shown in fig. 1) of a method for monitoring the state of the cabinet. The proximity sensor is triggered to output a low level when the cabinet door is closed and a high level when the cabinet door is open. According to the output level of the proximity sensor, the opening and closing states of the cabinet door of the data machine can be judged. The proximity sensor notifies the controller after detecting that the cabinet door is closed. The controller obtains the cabinet identification from the data storage module and then generates cabinet door closure information (the first 16 bits, bit 1 being 0, as shown in fig. 6 b) based on the closure status and the cabinet identification. And then the cabinet door closing information is sent to the robot through the wireless communication module. The robot receives the cabinet door closing information and then performs step 404.
In some alternative implementations of the present embodiment, the method further includes, in response to detecting the cabinet door opening, obtaining an opening time and adding to the cabinet door opening information, and in response to detecting the cabinet door closing, obtaining a closing time and adding to the cabinet door closing information. If the cabinet is provided with a real-time clock, the controller obtains the current time as the opening time when detecting that the cabinet door is opened through the proximity sensor, and generates cabinet door opening information according to the cabinet identification and the opening time (48 bits are total, and 1 st bit is 1 as shown in fig. 6 b). Similarly, when the controller detects that the cabinet door is closed through the proximity sensor, the controller obtains the current time as the closing time, and generates cabinet door closing information according to the cabinet identification and the closing time (48 bits in total, and 1 st bit is 0 as shown in fig. 6 b).
With continued reference to fig. 6a, fig. 6a is an application scenario of one embodiment of a method for monitoring cabinet status according to the present disclosure. In the application scene, a worker opens a cabinet door, a proximity sensor in the cabinet is triggered, a device A reports cabinet ID, door state and time information to a robot, the robot starts a monitoring camera according to the cabinet ID reported by the device A and reaches a corresponding coordinate point to monitor operation in the cabinet in the whole course, the worker closes the cabinet door after finishing the operation in the cabinet, the proximity sensor in the cabinet is triggered, the device A reports the cabinet ID, the door state and the time information to the robot, the robot receives the information reported by the device A, the monitoring is finished, the robot returns to an initial position, and a switching event and a monitoring video of the cabinet door are recorded and stored. And finally, the robot outputs an initial event of each cabinet door opening and closing event and image records during door opening operation to the server, so that the operation inside the cabinet is monitored in all directions.
