Whole-event acquisition testing system of intelligent ammeter based on virtual ammeter module

Abstract

The invention provides a whole-event acquisition testing system of an intelligent ammeter based on a virtual ammeter module. The whole-event acquisition testing system comprises a virtual ammeter module (I), a novel acquisition unit (II), an acquisition unit carrier communication module (III), a terminal carrier communication module (IV), an acquisition terminal (V) and a power utilization information acquisition main station (VI). By using the virtual ammeter module and the novel acquisition unit to replace a real carrier ammeter, a current situation that various events generated by the real ammeter are complicated and part of events are difficult to simulate is overcome; and a virtual ammeter can be used for simulating various events needed by a testing process. The whole-event acquisition testing system can be used for testing whole-event acquisition of three manners including initiative reporting, periodic acquisition and demand-based acquisition; and a supporting condition of the acquisition terminal and a power utilization information acquisition system to a whole-event acquisition function can be rapidly and effectively tested, and reliable operation of electric energy quality in an online monitoring system is guaranteed.

Description

technical field [0001] The invention relates to a function detection system of a centralized meter reading system for low-voltage power users, in particular to a smart meter full-event collection and test system based on a virtual power meter module, which belongs to the technical field of power metering. Background technique [0002] In recent years, low-voltage power line carrier communication technology has been widely used in the field of automatic meter reading, and the collection of electricity consumption has become fast and reliable. The demand for other electricity consumption information of power supply enterprises has also been continuously enriched, such as how to obtain timely information on abnormal power grids and energy meter failures. If these applications are not effectively realized, it will bring a lot of inconvenience to the subsequent development of the power system. [0003] In 2014, the State Grid Power Supply Company proposed to do a good job in the ...

Problems solved by technology

[0005] However, at present, due to the lack of a detection system for the full-event collection and testing of smart meters, and the lack of perfect software and hardware testing methods, it is difficult for real electric meters to simulate various events in the field, and it is impossible to evaluate the master station, terminal and electric energy meter of the collection system to support full-event collection. The situation directly restricts the promotion and application of all-event collection of smart meters
