I. System Overview
            
In the area where the power supply range of the complex transformer is not obvious, the ownership relationship between the collector and the concentrator in the power consumption information collection system is incorrect, resulting in a relatively low success rate of meter reading. To determine which collectors are under the concentrator, the traditional method of judgment is to manually check and determine the ownership of the collector by power failure. This method not only increases the workload of the debugger, reduces the work efficiency of the debugger, but also reduces the reliability of the power supply. It has affected the economic and intensive operation management of electric power enterprises. In order to effectively solve the problem of being able to accurately determine the collectors under the concentrator without power outages, reducing the workload of commissioning personnel and providing work efficiency, we have developed a This intelligent collector debugging system is suitable for helping debuggers to debug the collector without power failure, to complete the test of the collector belonging to the concentrator, and to analyze the reasons for the unsuccessful collection, and finally improve the user's electricity meter data The purpose of collecting success rates.

Third, the main functions of the system
3.1 Management functions of concentrator and collector
The concentrator and collector files exported by the electricity information collection system can be directly imported into the system, eliminating manual entry, and automatically categorizing the collectors of the same unit, providing convenience for system analysis. You can also manually enter the information of the collector and concentrator to facilitate debugging. When debugging, directly select the concentrator and collector in the relevant station area for testing.
3.2 Collector roll function
Reliable data exchange between electronic terminal equipment based on power line communication network, with communication relay capability. Through this debugging system, import a collector with an unclear ownership relationship, place the debugging system and equipment under the bench area, connect to the three-phase power supply in the bench area, poll the collector for the collector, respond to the collector of the collector and the same unit with it The collectors belong to the power supply of this station area, and form an analysis report, which can be exported. This function locates all collectors powered by the station at one time.
3.3 Collector listening concentrator function
By connecting the power of the collector, sending the collector's listening function, listening to the concentrator related to the collector, and determining which concentrator the collector belongs to by the signal strength. This function mainly tests a single collector, and it works well with the collector roll function.
3.4 System intelligent analysis function
Based on the response status, installation location, signal strength, and building information of the collector, intelligently analyze the ownership of the relevant collector, analyze and form an analysis report, and export it.
Fourth, the practical significance of the system
1. Correctly handle the relationship between the concentrator and the collector without power failure.
2. Improve the working efficiency of commissioning personnel.
3. Improve the reliability of power supply and reduce the impact of power outages on users.

Five, the main interface of the system software
System interface, including serial port configuration, acquisition strategy, concentrator information, collector information,
1) Listening information, communication messages, concentrator import, collector import, direct acquisition, primary relay, secondary relay, listening, etc.

2) Concentrator, collector import interface.

3) Collector interface, including relay address, phase, success flag, test time, signal quality, etc.

4) Interception information, including address, phase, signal strength, number of interceptions, number of relays, test time, etc.
