Description

Technical Field

[0001] The present invention belongs to the technical field of distribution automation terminal equipment detection, and in particular relates to a distribution automation equipment management system, method and medium based on true type testing. Background Art

[0002] The vigorous development of distribution automation systems has enabled remote perception of the operating status of distribution networks. The application of distribution automation terminal equipment (hereinafter referred to as "terminal equipment") can effectively monitor the operating status of massive distribution network equipment, thereby enabling remote management of in-service distribution network equipment. For this reason, terminal equipment testing, especially testing based on real-world testing, is crucial. Compared to traditional arrival testing, real-world testing can simulate fault conditions in the actual distribution network operating environment, including temperature and humidity, electromagnetic interference, vibration, and other factors. This allows for early detection of internal defects in terminal equipment and improves the reliability of distribution network power supply.

[0003] Through analysis of terminal equipment operational data over the past three years and discussions with power supply company operations and maintenance personnel, we determined that long-term stable operation is crucial for effectively improving fault diagnosis and diagnosis capabilities for terminal equipment on distribution lines, thereby enhancing power supply reliability. However, the actual performance of a particular type of terminal equipment, particularly those that have been installed on-site, have been in complex operating environments for a long time, and are located in locations without significant landmarks or reference points, remains largely unknown. The only available monitoring method is telesignaling and telemetering information from the master station. If no abnormal information is transmitted, it is assumed that the terminal equipment is operating stably from the current time until the next fault information transmission. This poses a risk to the stable operation of these terminal equipment. Based on this understanding, we intend to conduct full-scale capability testing on these typical terminal equipment to verify any changes in their functional and electrical performance after a period of operation.

[0004] Locating distribution automation equipment with these typical characteristics requires experienced operators who are familiar with the installation locations of distribution automation equipment on the substation outlet feeders. Operator turnover is high, and if experienced operators are temporarily unavailable or replaced, they can easily lose track of the distribution automation equipment installation locations, significantly reducing their efficiency and compromising the reliability of the distribution network.

[0005] Therefore, how to enable operation and maintenance personnel to accurately reach the area where the faulty equipment is located in the first place and reduce the time spent on searching for the equipment has become an urgent problem that technicians in this field need to solve. Summary of the Invention

[0006] To address the deficiencies in the prior art, the present invention aims to provide a distribution automation equipment management system, method, and medium based on real-type testing. This system facilitates operations and maintenance personnel to accurately locate and manage terminal devices with typical characteristics, quickly address channel failures such as terminal device failures or communication issues, and promptly eliminate them, thereby reducing operation and maintenance time and improving power supply reliability. At the same time, a terminal device identification library with typical characteristics is established to analyze the operating conditions and data of such terminal devices, facilitate management and retrieval of such devices, and provide a strong basis for the selection of distribution automation equipment.

[0007] The present invention adopts the following technical solutions.

[0008] The distribution automation equipment management system based on real-type test includes: cloud database, handheld device system and distribution automation terminal equipment. The distribution automation terminal equipment includes: radio frequency nameplate, and the handheld device system includes: handheld PDA, radio frequency identification antenna and reading and writing equipment.

[0009] The handheld device system is wirelessly connected to the cloud database, and the handheld device system is wirelessly connected to the distribution automation terminal equipment through the radio frequency identification antenna;

[0010] The cloud database is used to store basic data information and diagram data information of distribution automation terminal equipment. The handheld PDA can access, read and edit the basic data information and diagram data information of distribution automation terminal equipment in the cloud database through the data access channel.

[0011] When the distribution automation terminal equipment is located in a location without obvious landmark buildings or reference installation locations, the reader / writer writes the model data information of the distribution automation terminal equipment into the radio frequency nameplate to produce the model radio frequency nameplate, connects the model radio frequency nameplate of the distribution automation terminal equipment to the mainboard of the distribution automation terminal equipment, binds the model radio frequency nameplate with the basic data information of the distribution automation terminal equipment in the cloud database, and produces the model data radio frequency nameplate of the distribution automation terminal equipment;

[0012] When the distribution automation terminal equipment is located in a location with obvious landmark buildings and reference installation locations, the reading and writing equipment does not produce the graphic data radio frequency nameplate.

[0013] Among them, obvious landmark buildings and reference installation locations include: residential areas and factories.

[0014] Preferably, a secret key is set for the data access channel, and the handheld PDA needs the secret key authorization to open the data access channel.

[0015] The handheld PDA uses the radio frequency identification antenna to identify the graphic data radio frequency nameplate in the distribution automation terminal equipment, and the graphic data information of the distribution automation terminal equipment can be displayed on the authorized handheld PDA.

[0016] Among them, the basic data information of distribution automation terminal equipment includes: terminal equipment inherent ID code information and manufacturer information.

[0017] The graphic data information of the distribution automation terminal equipment includes: the installation location information of the distribution automation terminal equipment, the installation environment information, the installation climate information, the installation geographic information, the remote signaling information at the time of abnormality, the remote signaling information before and after the abnormality, and the SOE information.

[0018] The distribution automation equipment management method based on real-type test includes the following steps:

[0019] Step 1: Construction and installation of distribution automation terminal equipment, and production of radio frequency nameplates with model data;

[0020] Step 2: When a distribution automation terminal device has an abnormality, the regional location is determined immediately. If the distribution automation terminal device information is in the cloud database, it indicates that the distribution automation terminal device has typical characteristics. First, determine whether the defect is external to the distribution automation device itself. After eliminating the external defect, identify the abnormal distribution automation terminal device using the wireless radio frequency nameplate.

[0021] Step 3: After locating the abnormal terminal device, the information collected in the radio frequency nameplate of the image data is analyzed, and the telemetry information and SOE information of the abnormal terminal device provided by the distribution automation master station are automatically compared. At the same time, the online time and telesignaling accuracy of the abnormal terminal device are periodically analyzed and counted in the cloud database.

[0022] Preferably, the method for determining the external defects of the distribution automation terminal equipment in step 2 is: by querying whether the communication SIM card of the abnormal distribution automation terminal equipment is burned or in arrears, and querying whether the use of the communication channel between the abnormal distribution automation terminal equipment and the distribution automation master station is abnormal, so as to determine whether the distribution automation terminal equipment has an external defect.

[0023] Preferably, in step 1, the steps for making the pattern data radio frequency nameplate are as follows:

[0024] Step 1.1: For installation locations with obvious landmark buildings or references nearby, installation identification information entry and model data RF nameplate production are not performed. For distribution automation terminal equipment with complex operating environments and no obvious landmark buildings or reference installation locations, point-to-point model data information is entered into the cloud database, and model RF nameplates are produced using a reader / writer.

[0025] Step 1.2: In the cloud database, select the corresponding model of the distribution automation terminal equipment, improve its basic data information, establish the terminal equipment model data information, and use the reader to create the model data radio frequency nameplate;

[0026] Step 1.3: With the help of wireless radio frequency technology, non-contact two-way data communication is carried out through wireless radio frequency technology. The graphic data radio frequency nameplate of the distribution automation terminal equipment is read and written using wireless radio frequency, and the information is displayed on the handheld PDA device for reading and access.

[0027] Preferably, the method for determining the typical characteristics of the distribution automation terminal equipment is:

[0028] If the inherent device ID code information of the abnormal distribution automation terminal device is not found in the cloud database, it means that the device is installed in an area with obvious landmark buildings;

[0029] If the device exists in the cloud database, the distribution automation terminal device can be identified contactlessly through the radio frequency nameplate with image data, and the device can be located and selected.

[0030] A storage medium stores a computer program, which, when executed by a processor, implements the steps of a distribution automation equipment management method based on a real-type test.

[0031] The beneficial effect of the present invention is that, compared with the prior art,

[0032] 1) The present invention can effectively reduce the time that inexperienced operation and maintenance personnel spend searching and inspecting terminal equipment on the feeder due to personnel turnover and changes, thereby improving the efficiency of operation and maintenance work. By measuring abnormal monitoring information through the main station, it can be determined in the cloud database at the first time whether it is an abnormal terminal device with typical characteristics. According to the previous model data information, the area to which it belongs can be accurately located. Then, for the inspection of terminal equipment that cannot reach the designated installation location (temporary landform changes such as paddy fields, vegetation, and land acquisition) in the first time, non-contact positioning can be achieved, and faults other than the main body can be quickly eliminated, so as to better carry out operation and maintenance work. At the same time, cloud database information can be retrieved to conduct big data analysis on terminal equipment that has repeatedly experienced abnormalities, establish a multi-dimensional display of terminal equipment, and combine the distribution automation equipment status evaluation method to judge whether the supplier's terminal equipment quality is reliable and whether the installation process method is feasible, providing a strong basis for terminal equipment selection, improving the practicality of distribution automation equipment, and improving the power supply reliability of the distribution network.

[0033] 2) The present invention can realize contactless identification of different types of terminal devices of different models in complex operating environments and without obvious landmark buildings and reference installation locations through a handheld PDA. When approaching the installation location of the corresponding terminal device, the handheld PDA can identify the image data radio frequency nameplate through the RFID antenna, accurately sense the image data radio frequency nameplate that has been bound to the information in the cloud database, and present the image information of the bound terminal device in three dimensions for easy positioning; in addition, the installation location of the terminal device after arrival can be tracked, and regional information (environmental factors, climate factors, geographical factors) can be entered to analyze the impact of regional information on its operating status after a period of operation, thereby improving the practicality of distribution automation.

[0034] 3) The present invention closely meets the practical requirements of intelligent distribution network automation. It can truly grasp the actual location of terminal equipment in a complex operating environment without obvious landmark buildings and reference installation locations, and analyze the occurrence of faults in multiple dimensions, reducing the abnormal operation of distribution automation equipment due to channel defects, and reducing the time spent by operation and maintenance personnel to go to the site to find the fault point. It can not only save a lot of manpower and time, but also significantly improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 This is a schematic diagram of a distribution automation equipment management method based on a real-type test according to the present invention; DETAILED DESCRIPTION

[0036] The present application will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present application.

[0037] Example 1.

[0038] Distribution automation equipment management system based on real-type test. Figure 1 As shown, this is a schematic diagram of the distribution automation equipment management system based on real-type testing of the present invention.

[0039] Management system: cloud database, handheld device system and distribution automation terminal equipment. Distribution automation terminal equipment includes: radio frequency nameplate, handheld device system includes: handheld PDA, radio frequency identification antenna and reading and writing equipment, among which,

[0040] The handheld device system is wirelessly connected to the cloud database, and the handheld device system is wirelessly connected to the distribution automation terminal equipment through the radio frequency identification antenna;

[0041] The cloud database is used to store basic data information and diagram data information of distribution automation terminal equipment. The handheld PDA can access, read and edit the basic data information and diagram data information of distribution automation terminal equipment in the cloud database through the data access channel.

[0042] When the distribution automation terminal equipment is located in a location without obvious landmark buildings or reference installation locations, the reader / writer writes the distribution automation terminal equipment model information into the radio frequency nameplate to produce the model radio frequency nameplate. The model radio frequency nameplate of the distribution automation terminal equipment is connected to the terminal equipment motherboard. The terminal equipment operation data is collected and bound to the basic data information of the distribution automation terminal equipment in the cloud database to produce the model radio frequency nameplate of the distribution automation terminal equipment.

[0043] When the distribution automation terminal equipment is located in a location with obvious landmark buildings and reference installation locations, the reading and writing equipment does not produce the graphic data radio frequency nameplate.

[0044] The data access channel sets a secret key, and the handheld PDA needs the secret key to authorize the opening of the data access channel.

[0045] The handheld PDA uses the radio frequency identification antenna to identify the graphic data radio frequency nameplate in the distribution automation terminal equipment, and the graphic data information of the distribution automation terminal equipment can be displayed on the authorized handheld PDA.

[0046] The basic data information of distribution automation terminal equipment includes: terminal equipment inherent ID code information and manufacturer information.

[0047] The graphic data information of the distribution automation terminal equipment includes: the installation location information of the distribution automation terminal equipment, the installation environment information, the installation climate information, the installation geographic information, the remote signaling information at the time of abnormality, the remote signaling information before and after the abnormality, and the SOE information.

[0048] In this embodiment, preferably, obvious landmark buildings and reference installation locations include: residential areas and factories.

[0049] Example 2.

[0050] Distribution automation equipment management method based on real-type test.

[0051] The following steps are included:

[0052] Step 1: Construction and installation of distribution automation terminal equipment, and production of radio frequency nameplates with model data;

[0053] The steps for making the graphic data RF nameplate are as follows:

[0054] Step 1.1: For installation locations with obvious landmark buildings or references nearby, installation identification information entry and model data RF nameplate production are not performed. For distribution automation terminal equipment with complex operating environments and no obvious landmark buildings or reference installation locations, point-to-point model data information is entered into the cloud database, and model RF nameplates are produced using a reader / writer.

[0055] Step 1.2: In the cloud database, select the corresponding model of the distribution automation terminal equipment, improve its basic data information, establish the terminal equipment model data information, and use the reader to create the model data radio frequency nameplate;

[0056] Step 1.3: With the help of wireless radio frequency technology, non-contact two-way data communication is carried out through wireless radio frequency technology. The graphic data RF nameplate of the distribution automation terminal equipment is read and written using wireless radio frequency, thereby achieving the purpose of graphic data information exchange and displaying and accessing information on the handheld PDA device.

[0057] Step 2: When an abnormality occurs in the distribution automation terminal equipment, the regional location is determined immediately. If the distribution automation terminal equipment information is in the cloud database, it means that this distribution automation terminal equipment is a distribution automation terminal equipment with typical characteristics. First, determine whether the defect is external to the distribution automation terminal equipment. After eliminating the external defect, the abnormal distribution automation terminal equipment is identified using wireless radio frequency nameplate technology. The system then arrives at the area near the abnormal distribution automation terminal equipment and conducts a non-contact inspection and troubleshooting of such equipment.

[0058] The method for judging external defects of distribution automation terminal equipment is as follows: by checking whether the communication SIM card of abnormal distribution automation terminal equipment is burned or in arrears, and checking whether the use of the communication channel between the abnormal distribution automation terminal equipment and the distribution automation master station is abnormal, it can be judged whether there is an external defect of the distribution automation terminal equipment.

[0059] In step 3, after locating the abnormal terminal device, the system automatically compares the telemetry information and SOE information provided by the distribution automation master station with the information collected from the radio frequency nameplate by analyzing the image data. If the information matches the master station's measurement information, it indicates that there must be a defect in the terminal device's software or hardware. Responsibilities are clearly defined, and the supplier's technical personnel are dispatched to assist with operation and maintenance. At the same time, the cloud database periodically analyzes and compiles statistics on the abnormal terminal device's online time and telesignaling accuracy. This effectively compares the operational stability of terminal devices from different suppliers, providing a strong basis for terminal device selection.

[0060] The method for judging the typical characteristics of distribution automation terminal equipment is as follows:

[0061] If the inherent device ID code information of the abnormal distribution automation terminal device is not found in the cloud database, it means that the device is installed in an area with obvious landmark buildings, which is convenient for quick search;

[0062] If the device exists in the cloud database, the distribution automation terminal device can be identified contactlessly through the image model radio data frequency nameplate, and the device can be located and selected.

[0063] In this embodiment, a typical characteristic distribution automation terminal equipment identification library is preferably established, including: abnormal distribution automation terminal equipment weekly offline rate, weekly telesignaling incorrect rate, monthly offline rate, monthly telesignaling incorrect rate, environmental information, climate information and other characteristic information statistics. When the distribution automation master station detects abnormalities in the telesignaling collection of distribution automation terminal equipment, and when the distribution automation terminal in the identification library has abnormalities, when the distribution automation equipment information is retrieved through the identification library, it is first confirmed that the distribution automation terminal equipment itself is defective, and then the characteristic information is entered through information retrieval and the weekly and monthly characteristic information statistics of the distribution automation terminal equipment defect are automatically performed.

[0064] Example 3.

[0065] In specific implementation, the workflow of the distribution automation equipment management method based on real-type testing is as follows:

[0066] (1) System network architecture

[0067] The network architecture is built, cloud servers and databases are constructed, firewalls and gateways are configured, and data access channels are securely encrypted. A secret key is required to enter data information into the database. Only authorized handheld PDAs can decrypt and access the database to access, review and edit basic terminal device data information.

[0068] (2) Radio Frequency Identification

[0069] Establish a radio frequency nameplate for the terminal device. With the help of radio frequency identification technology, when the handheld device system is close to the radio frequency nameplate of the terminal device, it can recognize the radio frequency nameplate of the terminal device and fully display all the information bound in the radio frequency nameplate, so as to achieve the purpose of contactless identification of the terminal device.

[0070] (3) Construction of physical model information model

[0071] By applying information visualization technology in non-spatial fields, MVC geometric modeling is performed on terminal devices in the cloud database. Three areas are set up in the cloud database: model area, view area, and logic processing area.

[0072] In the model area, develop operation and maintenance templates for different types of terminal equipment according to operation and maintenance requirements. Build diagrams of different types of terminal equipment, enter basic equipment information such as the terminal equipment's inherent ID code and manufacturer, and build terminal equipment diagram information (input information).

[0073] During the installation of terminal equipment in the viewing area, the terminal equipment graphics information constructed in the model area is pushed to the video area. The handheld system displays the corresponding installed equipment graphics and product details. The graphics and RF nameplates are then created using a reader / writer device, comparing them to the terminal equipment installed on site. The graphics and RF nameplates are then installed in the terminal equipment and connected to the terminal's mainboard. The terminal management program collects terminal equipment operating information. The graphics and RF nameplates now have data collection and storage capabilities and are called graphics and data RF nameplates. When a terminal equipment anomaly occurs, the handheld system's reader / writer device uses radio frequency technology to contactlessly upload basic terminal equipment information, including telesignaling, and SOE (State of Equipment Efficiency) data, collected from the graphics and data RF nameplates to the viewing area. The data is then stored in a cloud database. The previously constructed terminal equipment graphics and data collected from the graphics and data RF nameplates are automatically bound and pushed to the viewing area. Accessing the cloud database viewing area through the handheld system allows for visual access to the bound terminal equipment graphics and telesignaling information and SOE (output information) collected before and after the fault.

[0074] In the processing logic area, within the cloud database, through logical processing, the terminal equipment's graphic model information, basic equipment information, telemetering information when a fault occurs, SOE information when a fault occurs, and other information are quickly integrated, and compared with the telemetering data on the distribution automation master station side, to conduct comparative analysis and statistics on terminal equipment operation and maintenance. The analysis and statistical results are pushed to the view area, and the view area is accessed through the handheld device system to visually implement the formulation and execution of operation and maintenance management strategies (processing logic).

[0075] The MVC architecture also enforces the separation of input information, output information, and processing logic, effectively protecting data security. Within the cloud database, different types of distribution automation terminal equipment models can be constructed, and equipment information can be input, compared with distribution automation master station telemetry information, and terminal equipment operating status can be independently determined.

[0076] (4) Handheld device system

[0077] The handheld device system includes: a handheld PDA (Personal Digital Assistant), an RFID (Radio Frequency Identification) antenna, and a reader / writer. The handheld PDA can read cloud database data after information encryption. At the same time, with the help of the configured RFID antenna and reader / writer, it can quickly identify the image data radio frequency nameplate.

[0078] (5) Visualization of physical objects to establish a model

[0079] Bind the terminal device's graphic model radio frequency nameplate 1 to the basic information of the terminal device in the database, and install the graphic model radio frequency nameplate 1 on the terminal device's mainboard. Use the terminal management program to store the terminal device's operating information, establish a graphic model data radio frequency nameplate, and use a reader / writer to achieve contactless identification. The various characteristic information of the terminal device stored in the graphic model data radio frequency nameplate is uploaded to the cloud database and displayed in a multi-dimensional and visual manner in the viewing area. The RFID antenna carried by the handheld PDA uses radio frequency technology to identify the graphic model data radio frequency nameplate in the terminal device. The graphic model data information of the terminal device can be displayed on the authorized handheld PDA through remote access to the cloud database viewing area. In addition, the terminal device information bound to the database can be edited through the authorized handheld PDA.

[0080] During the construction and installation of terminal equipment, operations and maintenance personnel should first identify the terminal equipment installation location, based on the distribution of the substation outlet feeders, in a complex operating environment with typical characteristics and without obvious landmark buildings or reference installation locations. After confirmation, they access the cloud database using a handheld terminal, select the previously created terminal equipment model information, and complete the verification of the installation location, environment, and other information. Using a reader / writer, they create a radio frequency nameplate containing the model data and install it inside the distribution automation terminal equipment.

[0081] The distribution automation real-world testing system features a typical 10kV distribution network structure (radial, multi-branch, multi-connection, hand-in-hand, and ring network) and neutral point grounding methods (ungrounded, low-resistance grounded, grounded via arc suppression coils, arc suppression coils and resistance grounded, etc.). It supports the testing of various feeder automation functions and has the ability to trigger various short-circuit, grounding, and disconnection faults at 10kV voltage levels with precisely controllable fault closing angles. It also provides the communication conditions necessary to implement various system-level functions of distribution automation equipment and the ability to simulate on-site temperature, humidity, electromagnetic interference, vibration, and rainfall under outdoor operating conditions. Real-world testing constructs multi-dimensional, real-world simulation operating scenarios, simulating real line faults and actual terminal equipment operating conditions, enabling the mass recovery of real-world test conditions. With the help of a real-type test system, when a simulated fault occurs, the collected telesignaling, telemetry information and SOE fault information of the terminal equipment at the time of and before and after the fault occurs are compared with the simulated fault information to determine whether the terminal equipment has uploaded the correct telesignaling and telemetry information, thereby solving the problem that the existing detection methods cannot fully reflect the practicality of the terminal equipment.

[0082] Based on the real-type test detection system, a distribution automation terminal equipment operation and maintenance management system and method based on real-type test is invented. Once an abnormality occurs in the terminal equipment, since the terminal equipment model data information has been entered into the cloud database during installation, the distribution automation terminal equipment operation and maintenance management method based on real-type test can accurately locate the terminal equipment, and the remote signaling, telemetry information and SOE abnormality information of the terminal equipment before and after the abnormality occurs are collected through radio frequency technology and compared with the data information collected on the distribution automation master station side, and non-contact operation and maintenance work is performed on it, thereby improving the work efficiency of the operation and maintenance personnel.

[0083] By using the distribution automation terminal equipment operation and maintenance management method based on real-type tests, the operation status of the terminal equipment entered in the cloud database can also be analyzed. First, the massive terminal devices installed arrive at the same material demand installation site at different times according to the different batches of inspection completion, and are installed randomly. For the terminal devices installed on the target line, the present invention can be used to analyze the operating status of the installed terminal devices. By building the terminal device image model information in the cloud database and binding it with the abnormal operation information in the radio frequency nameplate of the terminal device image model data collected contactlessly, the online status, telesignaling action status and access editing times of the terminal device within a certain period are counted, and the online status, telesignaling action status and FA judgment status of the terminal device provided by the distribution automation master station are compared and analyzed. If the action status of the terminal device is consistent with the action status provided by the master station, it means that the terminal device has high operating stability, strong data transmission capability, high software optimization degree, and strong hardware resistance to harsh environments; if some devices in the cloud database are accessed many times within a certain period, it means that the device has a high frequency of abnormalities and is inconsistent with the action status provided by the master station. The master station compares the terminal device operation data and finds omissions or underreporting, which means that the communication module of the terminal device is unstable and prone to problems with sending device abnormal information. The present invention analyzes and compiles statistics on the manufacturing process, main equipment operation status and operation stability of terminal equipment in operation, and provides a reference for the selection of distribution automation terminal equipment for distribution networks.

[0084] The beneficial effect of the present invention is that, compared with the prior art,

[0085] 1) The present invention can effectively reduce the time that inexperienced operation and maintenance personnel spend searching and inspecting terminal equipment on the feeder due to personnel turnover and changes, thereby improving the efficiency of operation and maintenance work. By measuring abnormal monitoring information through the main station, it can be determined in the cloud database at the first time whether it is an abnormal terminal device with typical characteristics. According to the previous model data information, the area to which it belongs can be accurately located. Then, for the inspection of terminal equipment that cannot reach the designated installation location (temporary landform changes such as paddy fields, vegetation, and land acquisition) in the first time, non-contact positioning can be achieved, and faults other than the main body can be quickly eliminated, so as to better carry out operation and maintenance work. At the same time, cloud database information can be retrieved to conduct big data analysis on terminal equipment that has repeatedly experienced abnormalities, establish a multi-dimensional display of terminal equipment, and combine the distribution automation equipment status evaluation method to judge whether the supplier's terminal equipment quality is reliable and whether the installation process method is feasible, providing a strong basis for terminal equipment selection, improving the practicality of distribution automation equipment, and improving the power supply reliability of the distribution network.

[0086] 2) The present invention can realize contactless identification of different types of terminal devices of different models in complex operating environments and without obvious landmark buildings and reference installation locations through a handheld PDA. When approaching the installation location of the corresponding terminal device, the handheld PDA can identify the image data radio frequency nameplate through the RFID antenna, accurately sense the image data radio frequency nameplate that has been bound to the information in the cloud database, and present the image information of the bound terminal device in three dimensions for easy positioning; in addition, the installation location of the terminal device after arrival can be tracked, and regional information (environmental factors, climate factors, geographical factors) can be entered to analyze the impact of regional information on its operating status after a period of operation, thereby improving the practicality of distribution automation.

[0087] 3) The present invention closely meets the practical requirements of intelligent distribution network automation. It can truly grasp the actual location of terminal equipment in a complex operating environment without obvious landmark buildings and reference installation locations, and analyze the occurrence of faults in multiple dimensions, reducing the abnormal operation of distribution automation equipment due to channel defects, and reducing the time spent by operation and maintenance personnel to go to the site to find the fault point. It can not only save a lot of manpower and time, but also significantly improve work efficiency.
