Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0040] Example 1:

[0041] Please refer to Figure 1 This embodiment provides a remote diagnostic system for a power supply, which is used to remotely diagnose a power supply system. The system includes a server 1, which is connected to the power supply to be diagnosed via the Internet. During remote diagnosis, server 1 receives external control commands, generates diagnostic commands based on the external control commands, and sends these commands to power supply 2 to be diagnosed. Power supply 2 collects diagnostic data based on the diagnostic commands and feeds this data back to server 1, completing the diagnosis of the power supply. This allows technicians to retrieve the diagnostic data from server 1 for analysis.

[0042] Specifically, such as Figure 1 In this embodiment, server 1 is wirelessly connected to wireless communication module 7 via router 5, forming one wireless communication loop. Simultaneously, server 1 also communicates with wireless communication module 7 via mobile communication base station 6, forming another wireless communication loop. In actual deployment, wireless communication module 7 is positioned at the power supply 2, and is in communication with the power supply.

[0043] Furthermore, the remote diagnosis system of this embodiment also includes an input device 3 that is communicatively connected to the server 1, and the input device 3 is used to input control instructions. The input device 3 of this embodiment includes but is not limited to a keyboard, a mouse, an input touch screen, etc.; in other embodiments, the technician also modifies or edits the program files in the server 1 through the input device 3.

[0044] The applicant's experiments revealed that when using the Modbus protocol (i.e., a serial communication protocol) to collect power supply diagnostic data, the number of power supply data types collected is limited and fixed due to the limited number of registers in the Modbus protocol. Technicians can only view a limited amount of monitoring information at the monitoring end, and due to this limited range of monitoring information, manual assistance is required for troubleshooting. Furthermore, due to the limited data collection and poor real-time performance of this system, there are monitoring blind spots, which often prevent effective fault diagnosis conclusions.

[0045] To address the aforementioned technical issues, the applicant, after numerous attempts and improvements, has redesigned the diagnostic instructions on the acquisition side (i.e., the server side of this embodiment). The control instructions input via input device 3 in this application include the power supply MCU map file, the names of the parameters to be collected, and the collection trigger conditions. The MCU map file includes the address information of all parameters in the power supply MCU, so the corresponding address information of the parameters to be collected can be found in the MCU map file. When the collection trigger conditions are met, the collection of some or all of the required parameters begins.

[0046] In this embodiment, server 1 is used to generate diagnostic instructions based on externally input control instructions. Specifically, the server first obtains the address information corresponding to the parameter names required to be collected in the control instructions from the power supply MCU map file; then, the server generates a diagnostic instruction based on the collection trigger condition, the parameter names required to be collected, and the address information corresponding to the parameter names required to be collected in the power supply MCU. In this embodiment, because the MCU map file covers all variable address information of the power supply system MCU program, the generated diagnostic instruction can collect parameter information of any number of power supplies, providing rich data support for power supply diagnosis and making the diagnostic results more accurate.

[0047] The power supply 2 of this embodiment includes a data acquisition module 21 , which is used to acquire diagnostic result data of the power supply according to a diagnostic instruction.

[0048] In one embodiment, the data acquisition module 21 is used to collect diagnostic result data of the power supply according to the diagnostic instruction, specifically including: after the data acquisition module receives the diagnostic instruction, it parses the acquisition trigger conditions, the parameter names to be collected, and the address information corresponding to the parameter names to be collected in the power supply MCU included in the diagnostic instruction; then reads the parameters to be collected from the corresponding address according to the address information corresponding to the parameter names to be collected in the power supply MCU.

[0049] In another embodiment, before collecting part or all of the parameters that need to be collected, the data acquisition module 21 also determines whether the collection trigger condition corresponding to the parameter is met. If so, the data of the parameter to be collected is read from the corresponding address according to the corresponding address information of the parameter to be collected in the power supply MCU; the diagnostic result data of this embodiment includes the data of the parameter to be collected read from the corresponding address.

[0050] In another embodiment, the data acquisition module 21 is used to collect diagnostic result data of the power supply according to the diagnostic instruction, and further includes: after receiving the diagnostic instruction, the data acquisition module 21 parses the acquisition trigger conditions, the parameter names to be collected, and the address information corresponding to the parameter names to be collected in the power supply MCU included in the diagnostic instruction; determines whether the acquisition trigger conditions are met, and if so, records the waveforms of the parameters to be collected for a preset period; the diagnostic result data includes the waveforms of the parameters to be collected for a preset period. For example, if the parameters to be collected include the battery output current, when the data acquisition module 21 determines that the output current of the current battery meets the preset acquisition trigger conditions, it indicates that the power supply has failed, and then records the current waveform of the power supply output for four consecutive cycles in real time.

[0051] The acquisition trigger conditions may be configured differently based on different parameters. For example, when waveform recording is required, the acquisition trigger conditions may include the recording period and type. For example, upon receiving a command, the data acquisition module 21 binds the parameters to be read according to the addressing command and, based on the acquisition trigger conditions, automatically records the instantaneous waveforms of several periods of the device during a specific fault condition, and immediately transmits the recorded waveforms back to the server 1.

[0052] In one embodiment, the remote diagnostic system further includes an output device 4, which is used to output diagnostic result data. For example, in this embodiment, the output device 4 is a display, which is used to display the diagnostic result data for easy viewing by technicians. In one embodiment, the input device 3 and the output device 4 can be replaced by existing touch-screen displays.

[0053] In one embodiment, the server 1 is also used to generate a corresponding data list and / or waveform image based on the diagnostic result data. For example, some data can be more clearly displayed through a data list or graph, and are drawn into a corresponding list or image. The output device 4 is also used to output the data list and / or waveform image drawn by the server 1.

[0054] In one embodiment, the server 1 is further configured to write the diagnosis result data into a diagnosis log after receiving the diagnosis result data, so as to facilitate subsequent review by technicians.

[0055] In one embodiment, the server 1 includes a fault diagnosis module, which is used to analyze the diagnosis result of the power supply based on the collected diagnosis result data using the existing machine learning model analysis method, and display the diagnosis result through the output device 4.

[0056] The use of the remote diagnosis system of the present application can effectively solve the technical defects of the existing monitoring and diagnosis system, which has limited and fixed types of data collection and can only collect current values ​​or single values ​​saved when a fault occurs, making it impossible to accurately locate the cause of the fault. The remote diagnosis system of the present application can realize the collection of any type of data, and also has the function of recording the instantaneous waveform of the fault, making the power supply diagnosis results more accurate.

[0059] Step 201: receiving a control instruction inputted from an external source;

[0060] Step 202: Generate a diagnostic instruction according to an externally input control instruction, and send the diagnostic instruction to the power supply to be diagnosed;

[0061] Step 203: Obtain the diagnostic result data returned by the power supply to be diagnosed.

[0062] The control instruction of this embodiment includes a power supply MCU map file, names of parameters to be collected, and collection trigger conditions; the MCU map file includes address information of all parameters in the power supply MCU.

[0063] Among them, such as Figure 3 In step 202, generating a diagnostic instruction according to an externally input control instruction includes:

[0064] Step 221: Obtain the address information corresponding to the parameter name to be collected in the control instruction in the power supply MCU from the power supply MCU map file;

[0065] Step 2022: Generate a diagnostic instruction according to the acquisition trigger condition, the name of the parameter to be acquired, and the address information corresponding to the name of the parameter to be acquired in the power supply MCU.

[0066] The remote diagnosis method of the present application can effectively solve the technical defects of the existing monitoring and diagnosis system, which has limited and fixed types of data collection and can only collect current values ​​or single values ​​saved when a fault occurs, making it impossible to accurately locate the cause of the fault. The remote diagnosis system of the present application can realize the collection of any type of data, and also has the function of recording the instantaneous waveform of the fault, making the power supply diagnosis results more accurate.
