[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present disclosure and are not used to limit the embodiments of the present disclosure.

[0035] First of all, before specifically introducing the technical solution of the embodiment of the present disclosure, the technical background or technical evolution context on which the embodiment of the present disclosure is based is introduced. Generally, in the field of communication connection of charging cabinets, the current technical background is: a router including multiple Ethernet ports is set in the charging cabinet, and each device in the charging cabinet establishes a communication connection with the server through the Ethernet port, which leads to the hardware circuit of the communication connection between the charging cabinet and the server being complex, and then leads to the problem of low reliability of the communication connection. Based on this background, the applicant has found through long-term model simulation research and development and the collection, demonstration and verification of experimental data that when the router is set up with an Ethernet port, transformers, demodulators and other equipment are required, which will lead to complex hardware circuit connections, frequent network disconnection failures, and low reliability of communication connections. How to reduce the setting of Ethernet ports and reduce the complexity of hardware circuits has become a difficult problem that needs to be solved urgently. In addition, it should be noted that the applicant has put in a lot of creative work from determining the technical solution to reduce the setting of Ethernet ports and the following embodiments.

[0036] In one embodiment, Figure 1 As shown, a charging cabinet is provided, which includes a networking unit 10, a processing unit 20 and a control unit 30; the networking unit 10 includes a target serial port 101 and a target interface 102; a communication connection is established between the networking unit 10 and the server; the control unit 30 is connected to the networking unit 10 through the target serial port 101 to establish a communication connection between the control unit 30 and the server; the processing unit 20 is connected to the networking unit 10 through the target interface 102 to establish a communication connection between the processing unit 20 and the server.

[0037] Among them, the networking unit 10 is an integrated circuit with communication connection function. The networking unit 10 can be embedded in the charging cabinet. In this embodiment, the networking unit 10 can insert a subscriber identification (Subscriber Identity Module, SIM) card, and realize the communication function after the SIM card is authenticated, thereby establishing a communication connection with the server. Optionally, the networking unit 10 may also have a routing function, and can be connected to other devices through the target serial port 101 and the target interface 102 set in the networking unit 10, so as to provide a communication network for other devices, wherein the serial port is also called a serial communication interface, which is a technology for transmitting data through serial communication, and the interface refers to a communication interface for signal transmission. Optionally, the target serial port 101 may be a universal asynchronous receiver / transmitter (UART) serial port, or the target serial port 101 may be a serial peripheral interface (SPI) for synchronous serial communication, or the target serial port 101 may be an integrated circuit bus (Intel-Integrated Circuitbus, IIC) interface for synchronous half-duplex communication, and the target interface 102 may be a universal serial bus (USB) interface, and this embodiment does not impose any restrictions on this.

[0038] Optionally, the communication connection established between the networking unit 10 and the server can be a communication connection of a 4G CAT1 network, or a communication connection of a 4G CAT4 network, or a communication connection of a 5G network, and this embodiment does not impose any restrictions on this.

[0039] The control unit 30 is an integrated circuit that controls other devices to complete various processing according to the received instructions. For example, the control unit 30 can be a single-chip microcomputer. The control unit 30 can be embedded in the charging cabinet. Optionally, a communication serial port matching the target serial port 101 of the networking unit 10 can be set in the control unit 30, and the target serial port 101 of the networking unit 10 is connected to the control unit 10 through the communication serial port. Alternatively, a communication interface matching the target interface 102 of the networking unit 10 can be set in the control unit 30, and the target interface 102 of the networking unit 10 is connected to the control unit 10 through the communication interface.

[0040] The processing unit 20 is an integrated circuit that processes received data according to received instructions. The processing unit 20 can be embedded in the charging cabinet. Optionally, a communication serial port matching the target serial port 101 of the networking unit 10 can be set in the processing unit 20 to be connected to the target serial port 101 of the networking unit 10, or a communication interface matching the target interface 102 of the networking unit 10 can be set in the processing unit 20 to be connected to the target interface 102 of the networking unit 10.

[0041] In this embodiment, a SIM card can be inserted into the networking unit 10, and the communication function can be realized through the SIM card, and a communication connection between the networking unit 10 and the server can be established to realize the networking function of the networking unit 10. It should be noted that in order to ensure the efficiency and accuracy of data transmission, the networking unit 10 can be connected to different devices through the target serial port 101 and the target interface 102, respectively, so as to provide a communication connection for other devices. When the networking unit 10 realizes the networking function, the networking unit 10 can turn on the routing function, the control unit 30 can be connected to the target serial port 101 of the networking unit 10 through the communication serial port, and the communication connection with the server can be realized through the networking unit 10, and the processing unit 20 can be connected to the target interface 102 through the communication interface, and the communication connection with the server can be realized through the networking unit 10.

[0042] The above-mentioned charging cabinet includes a networking unit, a processing unit and a control unit. The networking unit includes a target serial port and a target interface. A communication connection is established between the networking unit and the server, so that the control unit is connected to the networking unit through the target serial port, and a communication connection can be established between the control unit and the server, and the processing unit is connected to the networking unit through the target interface, and a communication connection can be established between the processing unit and the server. In the embodiment of the present application, the connection between the control unit and the server, and the communication connection between the processing unit and the server can be achieved only through the target serial port and the target interface of the networking unit, so that the charging cabinet does not need to be provided with a router including multiple Ethernet ports, avoiding the complex hardware circuit connection of the charging cabinet communication connection, which leads to the problem of easy network disconnection, and improves the reliability of the communication connection between the charging cabinet and the server; in addition, by respectively establishing the communication connection between the control unit and the server, and the communication connection between the processing unit and the server, a communication connection channel between the control unit and the server, and a communication connection channel between the processing unit and the server can be established, and the two communication connection channels do not interfere with each other, further ensuring the reliability of the communication connection between the charging cabinet and the server.

[0043] In one embodiment, please continue to refer to Figure 1The control unit 30 is used to send a first control instruction to the networking unit 10 through the target serial port 101, and the first control instruction is used to instruct the networking unit 10 to establish a communication connection between the control unit 30 and the server.

[0044] Among them, the first control instruction is sent by the control unit 30 to the networking unit 10. After receiving it, the networking unit 10 can recognize and execute the instruction of the response operation. In this embodiment, the first control instruction can be used to instruct the networking unit 10 to establish a communication connection between the control unit 30 and the server.

[0045] As an optional implementation, the first control instruction may also carry information to be sent by the control unit 30. Optionally, the information to be sent may be status information of the charging cabinet. For example, the status information may be the charging status of the battery of each charging compartment in the charging cabinet. Furthermore, the control unit 30 sends the first control instruction to the networking unit 10 through the target serial port 101. In addition to instructing the networking unit 10 to establish a communication connection between the control unit 30 and the server, the information to be sent by the control unit 30 may also be forwarded to the server.

[0046] As an optional implementation, the control unit 30 may also receive control instructions sent by the server through the networking unit 10, such as Figure 2 As shown, the control unit 30 may also be connected to the processing unit 20 via a communication serial port to send the received control instructions to the processing unit 20 .

[0047] In this embodiment, the control unit 30 can be connected to the target serial port 101 of the networking unit 10 through the communication serial port set on the control unit 30, and the first control instruction can be sent to the networking unit 10 through the target serial port 101. After receiving the first control instruction, the networking unit 10 can forward the first control instruction to the server, thereby sending the message in the control unit 30 to the server and establishing a communication connection between the control unit 30 and the server. Exemplarily, if the target serial port 101 is a UART serial port and the first control instruction is an AT instruction, the control unit 30 can send the AT instruction to the networking unit 10 through the UART serial port, and the networking unit 10 can forward the received AT instruction to the server to establish a communication connection between the control unit 30 and the server.

[0048] In an embodiment of the present application, the control unit is used to send a first control instruction to the networking unit through the target serial port, and can instruct the networking unit to establish a communication connection between the control unit and the server through the first control instruction, thereby realizing the communication connection function of the control unit, and then establishing a communication connection between the charging cabinet and the server.

[0049] In the scenario where the control unit 30 is connected to the networking unit 10 through the target serial port 101 to establish a communication connection between the control unit 30 and the server, the control unit 30 can determine whether to establish a connection with the server based on whether a response message sent by the networking unit 10 is received. Figure 1 The control unit 30 is used to determine that the control unit 30 establishes a communication connection with the server when receiving the response information sent by the networking unit 10; the response information is sent by the server to the networking unit 10 in response to the first control instruction.

[0050] The response message is generated by the server according to the first control instruction. It is understandable that after receiving the first control instruction generated by the control unit 30, the server can generate a response message according to the first control instruction and send the response message to the networking unit 10. After receiving the response message, the networking unit 10 can forward the response message to the control unit 30 according to the identification information carried in the response message.

[0051] In this embodiment, if the control unit 30 receives a response message sent by the networking unit 10, it means that the server has successfully received the first control instruction, that is, the control unit 30 and the server can communicate normally, then the control unit 30 can determine that a communication connection has been established with the server.

[0052] In an embodiment of the present application, the control unit is used to quickly determine that a communication connection is established between the control unit and the server based on the response message when the control unit receives the response information sent by the networking unit, so that the status information of the charging cabinet can be reported to the server based on the communication connection channel between the control unit and the server.

[0053] In the scenario where the control unit 30 determines to establish a communication connection with the server upon receiving the response information sent by the networking unit 10, the control unit 30 may determine whether the establishment of the communication connection with the server fails based on whether the response information is not received within a preset time period. Figure 1 The control unit 30 is further configured to determine that the communication connection with the server fails to be established when no response information is received within a preset time period.

[0054] It is understandable that if a network failure occurs, the first control instruction sent by the control unit 30 may not be sent to the server, and the server cannot generate a response message; or, after the server receives the first control instruction, the network fails, the response message generated by the server cannot be sent to the networking unit 10, and the control unit 30 cannot receive the response message; or, if a network delay occurs, the response message generated by the server may be sent to the networking unit 10 after a delay period, and the control unit 30 may receive the response message after the delay period. Optionally, the delay period may be 60ms, or 80ms. The delay period may also be set according to the actual communication connection rate requirements, and this embodiment does not impose any restrictions on this.

[0055] In this embodiment, the control unit 30 can determine whether the communication connection with the server is successful based on the waiting time of the received response message. If the control unit 30 does not receive a response message within the preset time, the control unit 30 can determine that the communication connection with the server has failed.

[0056] In an embodiment of the present application, the control unit can determine that the communication connection with the server has failed to be established by not receiving a response message within a preset time period, thereby being able to promptly determine whether the communication connection between the control unit and the server is normal, thereby avoiding the problem of abnormal communication connection and the inability to promptly repair the charging cabinet.

[0057] In the case where the control unit 30 does not receive a response message within a preset time period and determines that the communication connection with the server fails to be established, the control unit 30 may send a second control instruction to the networking unit 10 to instruct the networking unit 10 to power off and restart. Figure 1 The control unit 30 is also used to send a second control instruction to the networking unit 10 when it is determined that the communication connection with the server has failed to be established; the second control instruction is used to instruct the networking unit 10 to power off and restart.

[0058] Among them, the second control instruction is an instruction sent by the control unit 30 to the networking unit 10, so that the networking unit 10 performs a response operation according to the second control instruction. In this embodiment, the second control instruction is used to instruct the networking unit 10 to power off and restart. Exemplarily, the second control instruction can be a high level and a low level output through the output port of the control unit 30. Optionally, if the control unit 30 outputs a high level, the second control instruction can be to control the networking unit 10 to start; if the control unit 30 outputs a low level, the second control instruction can be to control the networking unit 10 to power off. It can be understood that if the communication connection function of the networking unit 10 fails, it may cause the failure of the communication connection between the control unit 30 and the server. Therefore, the networking unit 10 can be restarted to enable the networking unit 10 to re-establish the communication connection with the server.

[0059] In this embodiment, if the control unit 30 determines that the communication connection with the server has failed to be established, it can send a second control instruction to the networking unit 10, and control the networking unit 10 to power off and restart through the second control instruction, so as to control the networking unit 10 to re-establish the communication connection with the server.

[0060] In an embodiment of the present application, the control unit can, upon determining that the communication connection with the server has failed to be established, send a second control instruction to the networking unit, thereby controlling the networking unit to power off and restart, so that the networking unit can re-establish the communication connection with the server, and then the control unit can re-establish the communication connection with the service period through the networking unit.

[0061] In the above scenario where the control unit 30 sends the second control instruction to the networking unit 10 to instruct the networking unit 10 to power off and restart, the control unit 30 may send the second control instruction to the switch circuit 103 of the networking unit 10 to control the networking unit 10 to power off and restart through the switch circuit 103. In one embodiment, Figure 3 As shown, the networking unit 10 includes a switch circuit 103; a control unit 30 is used to send a second control instruction to the switch circuit 103, and control the networking unit 10 to power off and restart through the switch circuit 103.

[0062] Among them, the switch circuit 103 is used to control the conduction and power-off of the networking unit 10. Optionally, the switch circuit 103 can be a relay, or the switch circuit 103 can also be an isolating switch; or, the switch circuit 103 can also be a transistor switch, which is not limited in this embodiment.

[0063] In this embodiment, the control unit 30 can control the networking unit 10 to power off and restart by sending a second control instruction to the switch circuit 103 and controlling the conduction and disconnection of the switch circuit 103 through the second control instruction. By way of example, the control unit 30 can send a second control instruction carrying a low-level signal to the switch circuit 103 to control the networking unit 10 to power off. When the networking unit 10 is powered off, the control unit 30 can send a second control instruction carrying a high-level signal to the switch circuit 103 to control the networking unit 10 to power on and restart.

[0064] In the embodiment of the present application, the control unit can conveniently control the on and off of the switch circuit by sending a second control instruction to the switch circuit, thereby conveniently controlling the power off and restart of the networking unit, and further realizing the function of self-recovery of the networking unit when the network is disconnected. There is no need for operation and maintenance personnel to go to the charging cabinet site to power off and restart, thereby reducing the maintenance cost of the charging cabinet.

[0065] In one embodiment, Figure 4 As shown, the charging cabinet also includes: a monitoring camera 40, which includes a network interface; the processing unit 20 also includes a communication interface; the monitoring camera 40 is connected to the communication interface of the processing unit 20 through the network interface to establish a communication connection with the server.

[0066] Among them, the monitoring camera 40 can be used to record the operation of the charging cabinet, for example, it can record whether there is a battery charging in each charging compartment in the charging cabinet, and it can also record whether the cabinet door of each charging compartment is closed normally. Optionally, the data transmission method of the monitoring camera 40 can be wired transmission or wireless transmission. It should be noted that after the processing unit 20 establishes a communication connection with the server through the networking unit 10, it can also have a soft routing function, and other devices in the charging cabinet can establish a communication connection with the server by connecting to the processing unit 20.

[0067] In this embodiment, the monitoring camera 40 may include a network interface, which is connected to the communication interface of the processing unit 20 through the network interface to establish a communication connection between the monitoring camera 40 and the server, so that the monitoring data can be sent to the processing unit 20, and the monitoring data is forwarded to the server through the processing unit 20 to establish a communication connection with the server. Optionally, in this embodiment, the network interface in the monitoring camera 40 can be an RJ45 network port, through which another RJ45 network port can be connected, through which another RJ45 network port can be connected to a physical layer (Physical Layer, PHY) chip, through which the PHY chip can be connected to a media access control (Media Access Control, MAC) chip in the communication interface built into the processing unit 20, thereby establishing an Ethernet connection channel between the monitoring camera 40 and the processing unit 20, and sending monitoring data to the processing unit 20 through the Ethernet connection channel.

[0068] It can be understood that after receiving the monitoring data, the server can generate a response message based on the received monitoring data and send the response message to the networking unit 10. The networking unit 10 can forward the received response message to the processing unit 20. The processing unit 20 can determine that the communication connection between the monitoring camera 40 and the service interval has been successfully established upon receiving the response message.

[0069] As an optional implementation, if the processing unit 20 does not receive a response message within a preset time period, it can be determined that the communication connection between the surveillance camera 40 and the server has failed to be established. The processing unit 20 can send the information of the failure to establish the communication connection to the communication serial port of the control unit 30 through the communication serial port. After the control unit 30 receives the information of the failure to establish the communication connection, it can send a second control instruction to the switch circuit 103 of the networking unit 10 after a preset time period, so as to control the networking unit 10 to power off and restart through the switch circuit 103.

[0070] Optional, such as Figure 5 As shown, the charging cabinet provided in the embodiment of the present application may further include a display screen 50. The display screen 50 may be connected to the processing unit 20 by setting a display interface. When the processing unit 20 receives a display instruction sent by the control unit 30, the processing unit 20 may send the content to be displayed to the display screen 50 through the display interface for display according to the display instruction. Exemplarily, if the control unit 30 receives an instruction from the server to display the screen of the first charging compartment, the control unit 30 may send the instruction to the processing unit 20. After the processing unit 20 receives the instruction, it may send the screen of the first charging compartment through the display interface to the display screen 50 for display. Optionally, a real-time image may be displayed, or a historical image of a specified historical time period may be displayed.

[0071] In an embodiment of the present application, the charging cabinet also includes a monitoring camera, which can be connected to the communication interface of the processing unit through the included network interface, so that a communication connection with the server can be established, and the operating status information of the charging cabinet recorded by the monitoring camera can be transmitted to the server, so that the operation and maintenance personnel can obtain the operating status of the charging cabinet on the server side.

[0072] In one embodiment, Figure 6 As shown, the networking unit 10 and the processing unit 20 are integrated in the charging cabinet.

[0073] In this embodiment, the networking unit 10 and the processing unit 20 can be integrated into a circuit, and the integrated circuit can be set in the charging cabinet. The processing unit 20 can then directly send the received data to the networking unit 10 without the need to set up an additional communication interface. It is only necessary to set up the target serial port 101 to connect with the control unit 30 to establish a communication connection between different devices in the charging cabinet and the server.

[0074] In the embodiment of the present application, by integrating the networking unit and the processing unit in the charging cabinet, the line settings for establishing the communication connection between the networking unit and the processing unit can be reduced. Since the line connections are reduced, the problem of communication connection failure due to complex lines is avoided, which can further improve the reliability of the communication connection between the charging cabinet and the server.

[0075] For example, Figure 7 A complete description of the charging cabinet provided in the embodiment of the present application is given. The connection relationship between the networking unit 10, the control unit 30, the processing unit 20, the monitoring camera 40 and the display screen 50 in the charging cabinet provided in the embodiment of the present application can be as follows: Figure 7 As shown, the control unit 30 is connected to the UART serial port of the networking unit 10 through the UART serial port, so as to establish a communication connection with the server; the processing unit 20 is connected to the USB interface 102 of the networking unit 10 through the USB interface, so as to establish a communication connection with the server; the processing unit 20 is connected to the UART serial port of the control unit 30 through the UART serial port, so as to receive the control command sent by the server forwarded by the control unit 30; the monitoring camera 40 is connected to the MAC chip of the processing unit 20 through the RJ45 network port and the PHY chip, so as to send the monitoring data to the processing unit 20 and establish a communication connection with the server; the display screen 50 is connected to the processing unit 20 through the display interface, so as to display the display content sent by the processing unit 20; the antenna is used to transmit or receive electromagnetic waves.

[0076] In one embodiment, a communication connection method is also provided. The communication connection method can be applied to the charging cabinet. Figure 1 Taking the control unit in as an example, it includes: sending a first control instruction to the networking unit through the target serial port, and the first control instruction is used to instruct the networking unit to establish a communication connection between the control unit and the server.

[0077] Among them, the target serial port is a serial interface in the networking unit used to establish a communication connection with other devices. The first control instruction is sent by the control unit to the networking unit. After receiving it, the networking unit can recognize and execute the response operation instruction. In this embodiment, the first control instruction can be used to instruct the networking unit to establish a communication connection between the control unit and the server.

[0078] As an optional implementation, the first control instruction may also carry information to be sent by the control unit. The control unit sends the first control instruction to the networking unit through the target serial port, which can instruct the networking unit to establish a communication connection between the control unit and the server, and forward the information to be sent by the control unit to the server. Optionally, the information to be sent may be status information of the charging cabinet, for example, the status information may be the charging status of the battery of each charging compartment in the charging cabinet.

[0079] In this embodiment, the control unit can be connected to the target serial port of the networking unit through the communication serial port set on the control unit, and send a first control instruction to the networking unit through the target serial port. After receiving the first control instruction, the networking unit can forward the first control instruction to the server, thereby sending the message in the control unit to the server and establishing a communication connection between the control unit and the server.

[0080] In the embodiment of the present application, the control unit sends a first control instruction to the networking unit through the target serial port, which can instruct the networking unit to send the first control instruction to the server, so that a communication connection between the control unit and the server can be established. In the embodiment of the present application, the connection between the control unit and the server can be achieved only through the target serial port of the networking unit, and there is no need to set up a router including multiple Ethernet ports, which avoids the complex hardware circuit connection of the charging cabinet communication connection, which may lead to network disconnection problems, and improves the reliability of the communication connection between the charging cabinet and the server.

[0081] In one embodiment, the above method further includes: determining to establish a communication connection with the server when receiving response information sent by the networking unit; the response information is sent by the server to the networking unit in response to the first control instruction.

[0082] The response message is generated by the server according to the first control instruction. It is understandable that after receiving the first control instruction generated by the control unit, the server can generate a response message according to the first control instruction and send the response message to the networking unit. After receiving the response message, the networking unit can forward the response message to the control unit according to the identification information carried in the response message.

[0083] In this embodiment, if the control unit receives a response message sent by the networking unit, it means that the server has successfully received the first control instruction, that is, the control unit and the server can communicate normally, so the control unit can determine that a communication connection has been established with the server.

[0084] In an embodiment of the present application, the control unit is used to quickly determine that a communication connection is established between the control unit and the server based on the response message when the control unit receives the response information sent by the networking unit, so that the status information of the charging cabinet can be reported to the server based on the communication connection channel between the control unit and the server.

[0085] In one embodiment, the method further includes: if no response information is received within a preset time period, determining that the communication connection with the server has failed to be established.

[0086] It is understandable that if a network failure occurs, the first control instruction sent by the control unit may not be sent to the server, and the server cannot generate a response message, the networking unit cannot receive the response message, and the control unit cannot receive the response message.

[0087] In this embodiment, the control unit can determine whether the communication connection with the server is successful based on the waiting time of the received response message. If the control unit does not receive a response message within the preset time, the control unit can determine that the communication connection with the server has failed.

[0088] In an embodiment of the present application, the control unit can determine that the communication connection with the server has failed to be established by not receiving a response message within a preset time period, thereby being able to promptly determine whether the communication connection between the control unit and the server is normal, thereby avoiding the problem of abnormal communication connection and the inability to promptly repair the charging cabinet.

[0089] Optionally, when it is determined that the communication connection with the server has failed to be established, a second control instruction is sent to the networking unit; the second control instruction is used to instruct the networking unit to power off and restart.

[0090] The second control instruction is an instruction sent by the control unit to the networking unit so that the networking unit executes a response operation according to the second control instruction. It is understandable that if the communication connection function of the networking unit fails, it may cause the communication connection between the control unit and the server to fail to be established. Therefore, the networking unit can be restarted to enable the networking unit to re-establish the communication connection with the server.

[0091] In this embodiment, if the control unit determines that the communication connection with the server has failed to be established, a second control instruction can be sent to the networking unit, and the second control instruction can be used to control the networking unit to power off and restart so that the networking unit can re-establish the communication connection with the server.

[0092] In an embodiment of the present application, the control unit can, upon determining that the communication connection with the server has failed to be established, send a second control instruction to the networking unit, thereby controlling the networking unit to power off and restart, so that the networking unit can re-establish the communication connection with the server, and then the control unit can re-establish the communication connection with the service period through the networking unit.

[0093] Optionally, the networking unit includes a switching circuit; sending the second control instruction to the networking unit includes: sending the second control instruction to the switching circuit.

[0094] Among them, the switch circuit is used to control the conduction and power-off of the networking unit. Optionally, the switch circuit can be a relay, or the switch circuit can also be an isolating switch; or, the switch circuit can also be a transistor switch, which is not limited in this embodiment.

[0095] In this embodiment, the control unit can control the power-off and restart of the networking unit by sending a second control instruction to the switching circuit and controlling the conduction and disconnection of the switching circuit through the second control instruction. Exemplarily, the control unit can send a second control instruction carrying a low-level signal to the switching circuit to control the power-off of the networking unit. When the networking unit is powered off, the control unit can send a second control instruction carrying a high-level signal to the switching circuit to control the power-on and restart of the networking unit.

[0096] In the embodiment of the present application, the control unit can conveniently control the on and off of the switch circuit by sending a second control instruction to the switch circuit, thereby conveniently controlling the power off and restart of the networking unit, and further realizing the function of self-recovery of the networking unit when the network is disconnected. There is no need for operation and maintenance personnel to go to the charging cabinet site to power off and restart, thereby reducing the maintenance cost of the charging cabinet.
