The invention relates to the technical field of intelligent electric meter testing, in particular to a method and a system for debugging a carrier module of an intelligent electric meter.
Background
With the increasing development of smart power grids, the demand of countries in the world for intelligent user terminals is increasing. According to statistics, in the next 5 years, with the construction of the smart grid in all countries around the world, the number of smart meters installed in the world is as high as 2 hundred million. Similarly, in china, with the progress of building strong smart grids in China, the demand of smart meters as clients is also greatly increased.
The intelligent electric meter is an intelligent terminal of an intelligent power grid, is not an electric energy meter in the traditional sense, has the functions of intellectualization such as bidirectional multi-rate metering, user side control, bidirectional data communication of multiple data transmission modes, electricity larceny prevention and the like in order to adapt to the use of the intelligent power grid and new energy besides the metering function of basic electricity consumption of the traditional electric energy meter, and represents the development direction of an intelligent terminal of a future energy-saving intelligent power grid end user. Under the drive of the rapid development of the national smart grid, in recent years, domestic smart meter enterprises have great progress in the understanding and concept of technical innovation, the capital investment of the technical innovation and the construction of research and development bases and production bases, the investment of the industry leading enterprises on the smart meters is continuously increased, and great achievements are achieved in the aspects of the technical content of new products and the application of new technologies.
Because the PLC technology can directly adopt the existing power grid structure, redundant communication channels do not need to be additionally arranged, and communication lines are mastered by power enterprises, the PLC is very suitable for automatic intelligent meter reading. An automatic meter Reading System (AMR) is a System for data acquisition, transmission, and processing based on computer and communication technology, and is mainly used for automatically Reading meters of utility meters such as electric energy meters, water meters, gas meters, and the like. At present, the electricity consumption information acquisition resident meter reading system for power consumers in China comprises: the system comprises a main station, a concentrator and a meter, wherein more than 80% of meter reading channels under the concentrator are carrier channels, and a broadband carrier system communication or a narrowband carrier system communication is adopted.
The low-voltage power line carrier communication is a communication mode which uses a low-voltage power line as a carrier transmission channel, and the communication line does not need to be erected again, so that the low-voltage power line carrier communication becomes the most competitive communication mode in the existing automatic meter reading system. In an automatic meter reading system, a carrier module used in an intelligent electric meter bears the responsibility of power line carrier communication.
With the large-area popularization and use of the low-voltage power line carrier technology, the production test pressure of each production processing factory or generation processing factory is increased greatly, and the conventional complete machine assembly matching test mode is far from meeting the requirements of the current production test. The traditional test mode is that the carrier modules are tested one by one, the tested intelligent electric meter carrier modules are inserted into a base meter with a carrier function to be tested, and the test is finished and then pulled down one by one to be assembled. The method is complex in operation, low in production efficiency and extremely high in dependence on personnel, if a large number of carrier modules need to be tested urgently, the testing personnel need to overtime and overtake the testing point, so that the testing personnel are extremely easy to fatigue, and the testing efficiency is extremely low, so that the problem that how to improve the testing speed of the carrier modules needs to be solved urgently by various manufacturers at present is solved.
