[0064] As described in the background technology, the power distribution Internet of Things terminal debugging process in the existing technology has the problem of low debugging efficiency. The inventors have found that the reason for this problem is that the power distribution Internet of Things terminal debugging process generally involves manual installation and debugging of the distribution terminal, and the debugging process is generally cumbersome, resulting in low debugging efficiency.

[0065] Based on the above reasons, the present invention provides a power distribution IoT terminal debugging solution that can improve debugging efficiency.

[0066] In one embodiment, as shown in Figure 1, a distribution Internet of Things terminal debugging system is provided, including a cloud detection service center 100, a distribution Internet of Things terminal debugging device 200 and an intelligent gateway 300; the intelligent gateway 300 is used to obtain terminal information of the distribution Internet of Things terminal and upload the terminal information to the cloud detection service center 100; the cloud detection service center 100 is used to issue a test command to the distribution Internet of Things terminal debugging device 200 according to the terminal information; the distribution Internet of Things terminal debugging device 200 is used to perform signal conversion on the test command, determine the analog signal corresponding to the test command, and apply the analog signal to the distribution Internet of Things terminal; the intelligent gateway 300 is used to obtain a digital signal and transmit the digital signal to the cloud detection service center 100; the cloud detection service center 100 is used to determine the test result of the distribution Internet of Things terminal according to the digital signal.

[0067] A distribution IoT terminal refers to a device primarily used at the edge to collect data such as electrical quantities, environmental quantities, status quantities, and video images, perform edge computing, and transmit data via the network layer. These devices perform multiple functions, including data collection, processing, encryption, and transmission. For example, a distribution IoT terminal can collect electrical quantities and status quantities in real time, function as a server to transmit collected information, interoperate with other distribution IoT terminals, and issue control commands. Terminal information may include information collected by the distribution IoT terminal, device information, and more. Device information is not unique and may include, for example, the device name, model, device identification number, manufacturer, software and hardware version numbers, or IP address. A test command is a test command generated by the cloud detection service center 100 based on terminal information and sent to the debugging device of the distribution IoT terminal. A test result is a test result determined by the cloud detection service center 100 by comparing the received digital signal with a standard digital signal. This result indicates the accuracy of the parameters in the corresponding test command. The digital signal is converted from an analog signal by the distribution IoT terminal.

[0068] Specifically, during the debugging process of the distribution Internet of Things terminal, the intelligent gateway 300 can first obtain the terminal information of the distribution Internet of Things terminal and upload the terminal information to the cloud detection service center 100. The cloud detection service center 100 determines the operation status of the distribution Internet of Things terminal based on the terminal information, thereby determining the test command, and issues the test command to the distribution Internet of Things terminal debugging device 200. Thereafter, the distribution Internet of Things terminal debugging device 200 performs signal conversion on the test command, determines the analog signal corresponding to the test command, and applies the analog signal to the distribution Internet of Things terminal. The intelligent gateway 300 obtains the digital signal obtained by the distribution Internet of Things terminal by converting the analog signal, and transmits the digital signal to the cloud detection service center 100. The cloud detection service center 100 can determine the test result of the distribution Internet of Things terminal based on the digital signal.

[0069] In this embodiment, the distribution Internet of Things terminal debugging system includes a cloud detection service center 100, a distribution Internet of Things terminal debugging device 200 and an intelligent gateway 300; the intelligent gateway 300 is used to obtain the terminal information of the distribution Internet of Things terminal and upload the terminal information to the cloud detection service center 100; the cloud detection service center 100 is used to issue a test command to the distribution Internet of Things terminal debugging device 200 according to the terminal information; the distribution Internet of Things terminal debugging device 200 is used to perform signal conversion on the test command, determine the analog signal corresponding to the test command, and apply the analog signal to the distribution Internet of Things terminal; the intelligent gateway 300 is used to obtain the digital signal obtained by the distribution Internet of Things terminal converting the analog signal, and transmit the digital signal to the cloud detection service center 100; the cloud detection service center 100 is used to determine the test result of the distribution Internet of Things terminal based on the digital signal, which can realize fully automatic closed-loop debugging and greatly improve the distribution efficiency.

[0070] In one embodiment, as shown in Figure 1, the distribution Internet of Things terminal debugging system also includes a global Internet of Things platform 400; the global Internet of Things platform 400 is used to manage terminal device access to the distribution Internet of Things terminal; the smart gateway 300 specifically uploads the terminal information to the cloud detection service center 100 through the global Internet of Things platform 400; the cloud detection service center 100 specifically issues test commands to the distribution Internet of Things terminal debugging device through the global Internet of Things platform 400.

[0071] Among them, the global Internet of Things platform 400 is arranged at the platform layer, which is used to realize terminal access management functions such as distribution Internet of Things terminal access application, equipment registration, and configuration distribution. At the same time, it can also realize information transfer between the distribution Internet of Things terminal debugging device 200 and the cloud detection service center 100.

[0072] In this embodiment, the distribution IoT terminal debugging system also includes a global IoT platform 400, which can realize terminal access management functions such as distribution IoT terminal access application, device registration, and configuration issuance, and the smart gateway 300 specifically uploads the terminal information to the cloud detection service center 100 through the global IoT platform 400; the cloud detection service center 100 specifically issues test commands to the distribution IoT terminal debugging device through the global IoT platform 400, so that the information or commands can be uniformly received and sent through the global IoT platform to achieve consistency in information transmission.

[0073] In one embodiment, as shown in Figure 2, the cloud detection service center 100 is also used to issue control commands to the smart gateway 300 through the global Internet of Things platform 400; the smart gateway 300 is also used to upload corresponding test data to the global Internet of Things platform 400 based on the type of control command; the global Internet of Things platform 400 is also used to transmit test data to the cloud detection service center 100; the cloud detection service center 100 is also used to analyze the test data and determine the response status of the smart gateway 300.

[0074] The control command refers to a command issued by the cloud detection service center 100 to the smart gateway 300, which is used to control the smart gateway 300 to upload test data corresponding to the control command to monitor whether the response status of the smart gateway 300 is normal.

[0075] Specifically, before commissioning the power distribution IoT terminal, the power distribution IoT terminal commissioning system tests whether the smart gateway 300 can normally respond to the control command of the cloud detection service center 100. If the smart gateway 300 can normally respond to the control command of the cloud detection service center 100, the power distribution IoT terminal is commissioned to ensure the accuracy of the commissioning of the power distribution IoT terminal. That is, the cloud detection service center 100 can also be used to issue control commands to the smart gateway 300 through the global IoT platform 400. The smart gateway 300 uploads corresponding test data to the global IoT platform 400 based on the type of control command. The global IoT platform 400 transmits the test data to the cloud detection service center 100 through the KAFKA protocol. The cloud detection service center 100 analyzes the test data. If the test data is consistent with the standard test data, it can be determined that the response status of the smart gateway 300 is a normal response status.

[0076] In this embodiment, the cloud detection service center 100 sends a control command to the smart gateway 300 through the global Internet of Things platform 400, and finally determines the response status of the smart gateway 300 based on the received test data, which can ensure the accuracy of the distribution Internet of Things terminal debugging.

[0077] In one embodiment, there are multiple distribution IoT terminals, as shown in Figure 3. The cloud detection service center 100 is also used to send pre-debugging cases to the distribution IoT terminal debugging device 200 through the global IoT platform 400; the intelligent gateway 300 is also used to traverse each distribution IoT terminal, and based on the pre-debugging case, obtain the pre-debugging real-time data of each distribution IoT terminal, and transmit the obtained pre-debugging real-time data to the global IoT platform 400; the global IoT platform 400 is also used to transmit the received pre-debugging real-time data to the cloud detection service center 100; the cloud detection service center 100 is also used to determine the pre-debugging results of each distribution IoT terminal based on the received pre-debugging real-time data and record them for archiving.

[0078] Among them, the pre-debugging case refers to a test case issued for pre-debugging of the power distribution Internet of Things terminal, which is used to pre-debug the power distribution Internet of Things terminal, thereby pre-determining the debugging status of the power distribution Internet of Things terminal.

[0079] In this embodiment, before formally commissioning the distribution IoT terminal, it is necessary to pre-commission the distribution IoT terminal. For distribution IoT terminals with normal pre-commissioning results, formal commissioning is performed, and this process can also test the collection function of the intelligent gateway 300. The cloud detection service center 100 sends a pre-commissioning case to the distribution IoT terminal commissioning device 200 through the global IoT platform 400. The intelligent gateway 300 traverses each distribution IoT terminal and obtains the pre-commissioning real-time data of each distribution IoT terminal based on the pre-commissioning case. The obtained pre-commissioning real-time data is transmitted to the global IoT platform 400. The global IoT platform 400 then transmits the received pre-commissioning real-time data to the cloud detection service center 100. Finally, the cloud detection service center 100 determines the pre-commissioning results of each distribution IoT terminal based on the received pre-commissioning real-time data and records them for archiving. This can screen out distribution IoT terminals that are in normal working condition and reduce the possibility of commissioning failure due to distribution IoT terminal failure.

[0080] In one embodiment, as shown in FIG1 , the power distribution IoT terminal debugging system further includes a data center 500 , which is connected to the global IoT platform 400 and the cloud detection service center 100 ; the data center 500 is used to verify the terminal information transmitted through the global IoT platform 400 , and upload the terminal information to the cloud detection service center 100 if the verification is successful.

[0081] Specifically, the data center 500 is arranged at the platform layer and can verify the terminal information transmitted through the global Internet of Things platform 400. If the verification is successful, the terminal information will be uploaded to the cloud detection service center 100. If the verification fails, it means that an error occurred during the transmission of the terminal information, and an error message will be reported to notify technical personnel for verification.

[0082] In this embodiment, the power distribution IoT terminal debugging system also includes a data center 500, which can verify the terminal information transmitted through the global IoT platform 400, and upload the terminal information to the cloud detection service center 100 if the verification is passed, thereby ensuring the normal working state of the power distribution IoT terminal debugging.

[0083] In one embodiment, as shown in Figure 4, the cloud detection service center 100 includes a statistical analysis module 102, a test case determination module 104, a test case editing module 106 and a network module 108; the statistical analysis module 102 is used to perform statistical analysis on the distribution Internet of Things terminal based on terminal information and generate statistical analysis results; the terminal information includes the working status information of the distribution Internet of Things terminal after the last round of testing; the test case determination module 104 is used to determine the test case based on the statistical analysis results; the test case editing module 106 is used to edit the test case in response to the editing operation on the test case, obtain the updated test case and send it to the network module 108; the network module 108 is used to convert the updated test case into a test command, and issue the test command to the distribution Internet of Things terminal debugging device.

[0084] The statistical analysis results are determined based on the operating status information of the power distribution IoT terminals after the previous round of testing and are used to determine updated test cases. That is, the feasibility of the previous round of test cases can be determined based on the operating status information of the power distribution IoT terminals after the previous round of testing, and then the updated test cases can be determined.

[0085] Specifically, the cloud detection service center 100 is used to receive the working status information of the distribution IoT terminal after the last round of testing, determine the updated test case based on the working status information, generate and issue the corresponding test command, and repeat the process until the working status of the distribution IoT terminal meets the working status conditions. The specific implementation process is as follows: the statistical analysis module 102 in the cloud detection service center 100 performs statistical analysis on the distribution Internet of Things terminal based on the working status information of the distribution Internet of Things terminal after the previous round of testing contained in the terminal information, and generates statistical analysis results to determine the feasibility of the test case in the previous round of testing. Then, the test case determination module 104 determines the test case that best fits the statistical analysis result from multiple test cases based on the statistical analysis results. The test case editing module 106 edits the test case in response to the editing operation on the test case, obtains an updated test case determined based on the statistical analysis results, and sends it to the network module 108. Finally, the network module 108 converts the updated test case into a test command, and sends the test command to the distribution Internet of Things terminal debugging device, which can realize multiple updates and commissioning of the distribution Internet of Things terminal until the working status of the distribution Internet of Things terminal meets the working status conditions.

[0086] In one embodiment, as shown in Figure 5, the distribution Internet of Things terminal debugging device 200 includes a cloud platform interaction module 202, a multi-type communication interface module 204, a multi-type signal output module 206, and a test management module 208; the cloud platform interaction module 202 is used to obtain test commands; the multi-type communication interface module 204 is used to call the communication interface matching the test command and transmit the test command to the multi-type signal output module 206; the multi-type signal output module 206 is used to perform signal conversion on the test command and determine the analog signal corresponding to the test command; the test management module 208 is used to apply the analog signal to the distribution Internet of Things terminal.

[0087] Among them, the multi-type communication interface module 204 integrates communication interfaces such as Ethernet, serial port, Bluetooth, carrier, LoRa, Zigbee, and WiFi.

[0088] Specifically, the cloud platform interaction module 202 can obtain the test command issued by the cloud detection service center. After that, the multi-type communication interface module 204 matches the corresponding communication interface according to the signal type in the test command and calls the communication interface to transmit the test command to the multi-type signal output module 206. The multi-type signal output module 206 only needs to perform signal conversion on the test command and determine the analog signal corresponding to the test command. The test management module 208 can then apply the analog signal to the distribution Internet of Things terminal.

[0089] In this embodiment, by setting up a cloud platform interaction module 202, a multi-type communication interface module 204, a multi-type signal output module 206 and a test management module 208, the signal conversion of the test command can be realized, and the analog signal obtained by the signal conversion is applied to the power distribution Internet of Things terminal, thereby realizing digital power distribution to the power distribution Internet of Things terminal.

[0090] In one embodiment, the cloud platform interaction module 202 has a built-in interaction protocol, and the interaction protocol is used to obtain test commands.

[0091] Interaction protocols refer to the set of rules and standards that various devices or systems follow to achieve information exchange and communication within a network. These protocols specify how data is formatted, transmitted, received, and interpreted, ensuring that different devices or systems can communicate correctly.

[0092] Specifically, an interactive protocol is built into the cloud platform interactive module 202, and the cloud platform interactive module 202 can interact with the cloud detection service center to obtain test commands issued by the cloud detection service center to ensure the normal operation of the distribution Internet of Things terminal debugging system.

[0093] In one embodiment, as shown in Figure 5, the power distribution Internet of Things terminal debugging device 200 also includes a power distribution Internet of Things terminal simulation module 210; the test management module 208 is specifically used to apply the analog signal to the Internet of Things terminal simulation module 210, and when the Internet of Things terminal simulation module 210 completes the simulation, the analog signal is applied to the power distribution Internet of Things terminal.

[0094] Specifically, the cloud platform interaction module 202 can obtain the test command issued by the cloud detection service center. The multi-type communication interface module 204 matches the corresponding communication interface according to the signal type in the test command, and calls the communication interface to transmit the test command to the multi-type signal output module 206. The multi-type signal output module 206 converts the test command into a signal. After determining the analog signal corresponding to the test command, the IoT terminal simulation module 210 receives the analog signal for simulation. When the IoT terminal simulation module 210 completes the simulation, the analog signal is applied to the power distribution IoT terminal.

[0095] In this embodiment, by adding an IoT terminal simulation module and simulating the analog signal determined by the multi-type signal output module, the scenario of the analog signal being applied to the power distribution IoT terminal can be rehearsed, thereby improving the success rate of the power distribution IoT terminal debugging.

[0096] In one embodiment, the power distribution IoT terminal simulation module 210 has built-in multiple types of communication protocols, and cooperates with the test management module 208 to simulate the current sensor, voltage sensor, low-voltage smart switch, and low-voltage smart sensing terminal to collect signals, and complete the signal application simulation process to verify whether the implementation process after applying the analog signal to the power distribution IoT terminal is feasible.

[0097] In one embodiment, as shown in FIG. 5 , the test management module 208 is further connected to the cloud detection service center 100 to manage communication parameters and communication messages with the cloud detection service center 100 .

[0098] Specifically, the test management module 208 is connected to the cloud detection service center 100 and can be used to manage communication parameters and communication messages between the cloud detection service center 100 and the cloud detection service center 100 to ensure the communication order between the cloud detection service center 100 and the cloud detection service center 100.

[0099] In one embodiment, the test management module 208 includes a client system, a message management unit, a log management unit, and a test result management unit. The client system primarily manages communication parameters with the cloud detection service center 100. The message management unit primarily manages communication messages with the cloud detection service center 100. The log management module primarily records communication parameter logs and communication message logs with the cloud detection service center 100.

[0100] In one embodiment, as shown in Figure 6, the multi-type signal output module 206 includes a signal output switching unit 2062, and an electromagnetic signal output unit 2063, an electronic signal output unit 2064, an input signal output unit 2065 and an output signal output unit 2066 connected to the signal output switching unit 2062, and the signal output switching unit 2062 is connected to the cloud platform interaction module 202 or the multi-type communication interface module 204.

[0101] The electronic signal output unit 2064 can output an electronic signal of 0-20V with an output accuracy of 0.05%, and can realize analog quantity injection of the electronic power distribution terminal.

[0102] Specifically, when the signal output switching unit 2062 is connected to the cloud platform interaction module 202, it can find and access the signal output unit corresponding to the signal type according to the signal type in the test command; when the signal output switching unit 2062 is connected to the multi-type communication interface module 204, it can find and access the signal output unit corresponding to the communication interface determined by the multi-type communication interface module 204 to match the test command.

[0103] In this embodiment, by providing a signal output switching unit, free switching of multiple types of signal outputs can be achieved.

[0104] In one embodiment, the signal output switching module 2062 can realize automatic switching output of electromagnetic signals, electronic signals, output signals, and input signals.

[0105] In one embodiment, the electromagnetic signal output unit 2063 can output an electromagnetic voltage signal of 0-440V or an electromagnetic current signal of 0-40A with an output accuracy of 0.05%, thereby enabling analog quantity injection of electromagnetic power distribution terminals.

[0106] In one embodiment, the architecture of a cloud-based power distribution IoT terminal commissioning system is shown in Figure 7. The power distribution IoT terminal commissioning system includes a power distribution IoT terminal commissioning device, a power distribution IoT terminal and an intelligent gateway, a global IoT platform, and a cloud testing service center. The global IoT platform communicates with the power distribution IoT terminal commissioning device, the power distribution IoT terminal, and the intelligent gateway via a wireless private network. The intelligent gateway communicates with the power distribution IoT terminal via serial ports, Bluetooth, LoRa, and other methods. The power distribution IoT terminal commissioning device and the power distribution IoT terminal are physically wired. The power distribution IoT terminal primarily consists of electrical and non-electrical sensors. The cloud detection service center sends a test command to the distribution IoT terminal debugging device through the global IoT platform. The distribution IoT terminal debugging device applies the corresponding analog signal to the distribution IoT terminal according to the test command. The distribution IoT terminal transmits the collected digital signal to the smart gateway. The smart gateway transmits the digital signal to the global IoT platform through the MQTT (Message Queuing Telemetry Transport) protocol. The global IoT platform then transmits the digital signal to the cloud detection service center. The cloud detection service center intelligently analyzes the digital signal to obtain the test results and archives them electronically.

[0107] In one embodiment, a power distribution IoT terminal debugging system and method based on a cloud platform is characterized by including a cloud detection service center, a data center, a global IoT platform, a power distribution IoT terminal debugging tool, an intelligent gateway, and a power distribution IoT terminal.

[0108] The cloud detection service center is arranged at the application layer. Its main function is to receive the digital signals of the intelligent gateway forwarded by the global Internet of Things platform. It can issue corresponding test commands based on the digital signals, draw test conclusions based on the intelligent analysis of the digital signals, and generate test reports for archiving.

[0109] The data center is located at the platform layer and is used to receive and verify digital signals.

[0110] The global IoT platform is deployed at the platform layer to transmit test data to the cloud testing service center.

[0111] The power distribution IoT terminal debugging device is connected to the global IoT platform through a wireless private network, and can convert the test commands issued by the cloud detection service center into corresponding analog signals and apply them to the power distribution IoT terminal to be tested.

[0112] The intelligent gateway is a key node for forwarding digital signals. It communicates southbound with distribution IoT terminals via serial ports, Bluetooth, LoRa, and other methods, and northbound sends information to the global IoT platform via a wireless private network. It primarily comprises a collection module and a forwarding module. The collection module aggregates digital signals from distribution IoT terminals. The forwarding module matches digital signals with corresponding point numbers in the physical model and transmits them to the global IoT platform via the MQTT protocol. The global IoT platform then transmits the digital signals to the cloud detection service center. Distribution IoT terminals include micro current sensors, temperature and humidity sensors, and water level sensors, enabling the collection of electrical and environmental information from the low-voltage distribution network. Their built-in acquisition chips and analog-to-digital conversion chips convert the collected analog signals into digital signals, which are then transmitted to the intelligent gateway via the corresponding communication modules. The plug-and-test module receives communication information from the device under test from the cloud detection service center, automatically modifies the local communication configuration, and communicates with the distribution IoT terminals. Distribution IoT terminals include a signal acquisition module, a signal forwarding module, and a control module. The signal acquisition module enables real-time collection of electrical and status data. The signal forwarding module, acting as a server, transmits information collected by the signal acquisition module to the intelligent gateway. The control module enables interoperability with other power distribution IoT terminals. By sending control commands to the intelligent gateway, the intelligent gateway converts the control commands into the protocol of the corresponding power distribution IoT terminal and issues execution commands based on the physical model.

[0113] The intelligent gateway includes a collection module and a signal forwarding module. The collection module aggregates digital signals from distribution IoT terminals. The signal forwarding module maps the digital signals collected by the collection module to the physical model point table and forwards them to the cloud detection service center via the MQTT protocol.

[0114] The cloud testing service center is developed based on the global Internet of Things platform and can also include a device information module, which mainly records test information. The test information includes name, model, manufacturer, device identification number, software and hardware version numbers, and IP (Internet Protocol Address) address.

[0115] In one embodiment, a cloud-based power distribution IoT terminal commissioning system supports testing of power distribution IoT edge devices and terminal devices, as shown in the following table, and can support user-defined extensions.

[0116] In one embodiment, a cloud-based power distribution IoT terminal commissioning system supports three test modes: full digital simulation testing, digital / analog crossover testing, and real-world simulation testing. Full digital simulation testing is primarily used for smart gateway protocol conformance testing and simulates data transmission from end devices. Digital / analog crossover testing is primarily used for testing the management and acquisition functions of smart gateways. Real-world simulation testing is primarily used for testing the transmission function of smart gateways and the functional performance of end devices, verifying the transmission function of smart gateways and the functions and performance of end devices by simulating a real-world environment.

[0117] Taking the intelligent gateway management function test as an example, the intelligent gateway device management functions include: event management function, parameter setting and query, remote browsing function, message storage function, edge computing function, automatic recovery function, device management function, container management, application software and management.

[0118] Taking the intelligent gateway acquisition function test as an example, the intelligent gateway acquisition function test content includes: working power supply impact detection (DC power supply, AC power supply, anti-ground fault capability, backup power supply); basic performance test (AC analog error test, power basic error measurement, power factor basic error measurement, frequency basic error measurement); distribution acquisition function detection; advanced analysis and statistical function detection (data statistics function, low-voltage switch control function, substation operation environment monitoring) device power consumption detection; continuous power-on stability detection.

[0119] In one embodiment, the core of each of the above debugging scenarios is the normal collection and transmission of cloud-pipeline data, enabling data communication between the power distribution IoT terminal and the intelligent gateway, and between the intelligent and global IoT platforms. Before debugging, the debugging engineer needs to perform configuration, and the steps are as follows:

[0120] Step 1: After the commissioning equipment arrives, the materials center will enter the primary and secondary equipment ledgers. After the primary and secondary equipment ledgers are entered, as shown in Figure 8, the southbound protocol model must be managed. This process is completed in five steps. First, the commissioning personnel parses the device protocol point table based on the point table document provided by the manufacturer. Second, the commissioning personnel selects the required acquisition variables, enters the variable's starting address, register number, and coefficient. Third, the object model service attributes are matched, matching the device variables with the IoT service attributes. Fourth, a configuration file group is generated, including configuration files related to IoT registration, object model, and southbound device communication data acquisition. Fifth, the commissioning personnel uses their mobile phone to scan the QR code of the smart gateway with the EasyLink client to query the device center for basic gateway information. Scanning the virtual private network card QR code submits the registration to the IoT platform. The device center will query the newly added gateway information, select the corresponding gateway, and after selection, the southbound protocol model is sent to the commissioning smart gateway.

[0121] Step 2: Based on the device's factory baud rate and communication address, the system intelligently recommends baud rate settings for each serial port. As shown in Figure 9, the system scans the sensor's QR code to retrieve sensor attribute information from the device center. The system then selects the serial number of the primary device to which it belongs, and updates the associated information to the device center. The device center then obtains the installed and wired device information and, based on the baud rate and communication address, recommends a new serial port number or proposes parameter modifications. The system checks whether the data is within the normal range. If not, the system recommends a solution, which the commissioning personnel can promptly correct.

[0122] Step 3: Data Debugging. As shown in Figure 10, the debugging engineer powers on the smart gateway. After the intelligent system is initialized, they scan the QR code on their mobile phone using the EasyLink client to obtain the download address for the latest gateway application client. The installation package is then delivered to the smart gateway via the MQS (Message Queue Service) message / file server on the global IoT platform. The gateway stores the file locally. If the smart gateway configuration needs to be updated, the debugging engineer issues a configuration update command on the mobile client. After the update is complete, the smart gateway is restarted to update the configuration.

[0123] Step 4: Data Verification. After the configuration update is complete, verify that the data uploaded to the smart gateway is correct. If the data is correct, save the configuration and perform standardized debugging. If the data upload is abnormal, the mobile phone scan code in the EasyLink client will display a configuration check error. The debugger will modify the configuration and generate a new configuration file and upload it to the file server.

[0124] In one embodiment, during on-site installation, the debugged power distribution IoT terminal is plug-and-play, eliminating the need for repeated, tedious debugging. This significantly reduces installation and debugging time and improves work efficiency. This system breaks through traditional manual debugging methods, enabling automated closed-loop debugging of power distribution IoT terminals. This automated closed-loop debugging approach not only avoids human error but also makes the debugging process more accurate and efficient. Furthermore, debugging reports can be automatically generated, significantly reducing the workload of manual report preparation.

[0125] By connecting the power distribution IoT terminal and its debugging device with a cloud-based testing service center, this system enables remote commissioning and monitoring of warehouse power distribution IoT terminals. This remote operation reduces manual intervention, not only improving commissioning efficiency but also further standardizing the commissioning process, making the entire operation more scientific and standardized. In summary, this power distribution IoT terminal commissioning system and method has significant technical effects and advantages, and is of great significance and application value in improving work efficiency, reducing manual operations, and standardizing operational procedures.

[0126] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0127] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
