Description

technical field [0001] The invention relates to the technical field of electrical measurement, in particular to a fault diagnosis device for an electricity consumption information collection system. Background technique [0002] Since 2011, the State Grid Corporation has put forward the requirement of "full coverage and full collection" of residents' electricity consumption information and power energy data of each plant and station. According to the requirements of the State Grid Corporation of China, the provincial grid companies need to gradually strengthen the management and control of various power plants and stations, and urgently need to know real-time data and information such as power generation, sales, and power supply reliability, so as to fully grasp the operating conditions of power companies . The power collection system of State Grid Corporation is composed of hundreds of millions of smart power meters and collection terminals. It has been operating in comple...

AI Technical Summary

Problems solved by technology

The function of the master station program of the handheld (PDA) is relatively simple, usually only a few common commands are implemented, the protocol analysis ability is poor, and the screen interface is small, and the user interaction is poor. Generally, only a few serial communication methods such as infrared communication are supported.

Installing a stand-alone master station software on a laptop can realize communication with field devices, but laptops generally only support RS232 and Ethernet interfaces, and do not support RS485, WiFi, 2G (GPRS or CDMA), 3G and 4G communications. Not very versatile

In addition, the existing station area phase recognition instrument can already realize the function of station area phase identification, but it is large in size and is an independent device. The interface standard is not uniform, and it cannot be connected with the fault intelligent diagnosis equipment of the power consumption information collection system.
