Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0029] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Figure 1 A schematic diagram of a terminal automatic debugging system based on a distribution automation system provided by an exemplary embodiment of the present application is shown. Figure 1 The system includes an automatic debugging server 110, a mobile terminal 120 and a matching relay protection device 130.

[0031] In the embodiments of the present application, the mobile terminal can be implemented as a commonly used handheld terminal device, such as a mobile phone, tablet computer, or industrial equipment. Optionally, the mobile terminal includes an application program, and personnel generate data through operations within the application program, which then transmits corresponding signals to a corresponding relay device associated with the system. The automatic debugging server and the mobile terminal are wirelessly connected for remote communication.

[0032] In the embodiments of this application, the accompanying relay acts as an alternative to the actual instrument for transmitting current and voltage or forwarding data. Upon receiving the telesignaling and telemetering list and the calibration value for the increase in quantity from the mobile terminal, it performs the increase in quantity. It should be noted that in the embodiments of this application, the telesignaling signal is a digital signal indicating digital quantities such as the opening and closing of a switch, while the telemetering signal is an analog signal indicating numerical values such as current and voltage. The embodiments of this application do not limit the specific content of the telesignaling and telemetering list.

[0033] In the embodiment of the present application, the automatic debugging server can be implemented as a physical server or as a cloud server. The present application does not limit the specific structure of the automatic debugging server.

[0034] In this case, the automatic debugging server is connected to the mobile terminal, which is in turn connected to the associated relay. The mobile terminal is configured to receive encrypted messages, parse the encrypted messages to obtain a list of telesignaling and telemetry data to be tested, and a calibration value for the added value. The list and calibration value are sent to the associated relay. The associated relay receives the list and calibration value, and performs data addition based on the list and calibration value. The automatic debugging server receives real-time data from the distribution automatic terminal 140 after performing telesignaling and telemetry data addition. The real-time data is sent to the mobile terminal. The mobile terminal generates debugging results based on the real-time data and calibration value for the added value.

[0035] In an alternative embodiment, please refer to Figure 2 The system further includes a WEB server 150. The WEB server is communicatively connected with the automatic debugging server.

[0036] In this embodiment of the present application, the web server corresponds to a web interface, which is also the interface for staff to edit work order information and generate table data. In this case, the web server is also used to receive a work order generation signal; based on the work order generation signal, generate a debugging work order corresponding to the telesignaling and telemetry list; and send the debugging work order to the automatic debugging server. The automatic debugging server is used to synchronize the debugging work order with the mobile terminal.

[0037] In an optional embodiment, the automatic debugging server is further configured to generate an encrypted message based on the debugging work order; and send the encrypted message to the mobile terminal.

[0038] Optionally, in an embodiment of the present application, data transmission between the automatic debugging server and the terminal is implemented as an encrypted message based on the IEC-104 protocol.

[0039] In an alternative embodiment, please refer to Figure 2The system also includes a production control regional server 160 and a management information regional server 170; the production control regional server is communicatively connected to the distribution automation terminal; the management information regional server is communicatively connected to the production control region via a message bus; the production control regional server is also used to receive real-time data; the real-time data is sent to the management information regional server via the message bus; the management information regional server is used to store the real-time data and forward it to the automatic debugging server.

[0040] Please refer to Figure 2 After the distribution automation communication terminal, under the control of the supporting relay protection device, performs telesignaling and telemetering data addition, the data generated by the distribution automation communication terminal is transmitted to the production control regional server and synchronized in real time between the production control regional server and the management information regional server. At this time, the data received by the automatic commissioning server is the data synchronized in real time by the management information regional server.

[0041] In an optional embodiment, the management information zone server is implemented as a SCADA server.

[0042] In an optional embodiment, the mobile terminal is further configured to synchronize the debugging results to the automatic debugging server. In this case, the automatic debugging server is further configured to synchronize the test results with the web server, so that the synchronization results are displayed on the corresponding interface of the web server.

[0043] In actual operation, the overall workflow is as follows:

[0044] On-site commissioning personnel need to verify that the signal from a distribution automation terminal can be properly transmitted to the distribution automation master station and accurately displayed. However, the master station does not have idle operation and maintenance personnel to assist with the commissioning. In this case, a mobile terminal can be used to connect the output of the supporting relay to the terminal block of the terminal under test. The mobile terminal can then issue a task to the supporting relay, controlling the supporting relay to automatically increase the specified telesignaling and telemetry. The mobile terminal then compares the increase result with the baseline calibration value. If the error range is within, the increase is determined to be correct; otherwise, the increase is rejected. After the commissioning is completed, the mobile terminal automatically uploads all commissioning results to the automatic commissioning server, also known as the master station. The master station operation and maintenance personnel can review the commissioning results on the web page.

[0045] To sum up, the system provided in the embodiment of the present application, during the process of debugging the distribution automation terminal, when the mobile terminal receives and parses the encrypted message, determines the telesignaling and telemetry list and the added reference calibration value for the distribution automation terminal, and synchronizes them with the matching relay protection instrument, which forwards the signal. After the automatic debugging server receives the real-time detection data, it synchronizes the data with the mobile terminal, and finally the mobile terminal generates the debugging results.

[0046] The system has at least the following advantages:

[0047] (1) Terminal debugging no longer requires real-time participation of the main station operation and maintenance personnel, saving the manpower and time costs of the main station.

[0048] (2) It can realize the full process and standardized control of terminal debugging.

[0049] (3) Significantly improve terminal debugging efficiency and debugging quality.

[0050] (4) It can reduce the communication costs of on-site debugging personnel, break the situation of limited debugging time under the old model, and liberate labor productivity.

[0051] The above are only optional embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
