Abstract

The invention relates to an automatic control system for ammeter, which comprises: a computer control and management system, and some concentrators connected to some ammeters by means of RF and PLC. Wherein, connecting the computer system and concentrator by at least one means ob PSTN, digital-transmission radio station and GPRS; and connecting the ammeters each other by means of RF and PLC. This invention combines RF and PLC technique, builds a network platform for intelligent control, provides reliable criterion for electric inspection, and improves ammeter management level.

Description

Technical field [0001] The invention relates to an electric meter centralized management and automatic monitoring system, in particular to an electric meter automatic control system suitable for centralized management of electric meters in electric power systems. Background technique [0002] Electric meter management has always been a very troublesome matter that the power supply department is very concerned about. In the traditional meter reading charging and electricity monitoring, special personnel go to the user's site to read and check the meter, and the collected meter data is collected to the power supply department, and the power supply department issues tickets and charges according to relevant regulations. In this way, a large number of copying personnel are required, the labor intensity is high, the efficiency is low, and human errors may occur, resulting in some unnecessary social impacts, and at the same time affecting the corporate image of the power supply de...
