Remote automatic centralized control monitoring meter reading system

Abstract

The invention relates to a long-distance automatic centralized control monitoring meter reading system, which is characterized in that: data collection terminals take an embedding type processor as the core and is provided with an external data memory EEPROM and two extension RS-485 serial port communication modules; the modules are provided with corresponding communication interfaces with one interface used to hang electronic electric energy meters and the other interface connected with a data concentrator; at least two electronic electric energy meters are hung under the data collection terminals; the data concentrator takes an embedding type ARM processor as the core and at the same time, is provided with peripheral equipment including a program memory FLASH and a data memory SDRAM, an extension RS-485 serial port communication module and a long-distance communication module; the RS-485 serial port communication module is connected with the data collection terminals; at least two data collection terminals are hung under the data concentrator; a long-distance management upper computer, based on an ordinary PC and provided with a database server, is communicated with two data concentrators at least through the long-distance communication module.

Description

technical field [0001] The invention relates to a computer-based remote monitoring management system, in particular to a meter reading data management system based on RS-485 and Ethernet or GPRS, CDMA wireless communication computer for remote monitoring. Background technique [0002] The urban power grid has spread all over every corner of the town. In order to measure the user's electricity consumption, the electric energy meter is placed in every building of the residential area. In cities and towns with poor conditions, reading the data of these electric energy meters has been done manually for a long time, that is, every time the meter is read, the meter reader needs to knock on the door of each building to ask the residents to open the security door of the building before they can enter the floor Open the meter box to read the data on the electric energy meter with the naked eye, and manually record the data, so the efficiency of meter reading is extremely low, and man...
