A remote intelligent meter writing method and remote intelligent meter writing system

Abstract

The invention belongs to a remote intelligent meter reading system field, is a remote intelligent meter reading system configured being used for remoter meter reading, bidirectional data transmission of an electrical meter, a water meter and an gas meter. Transmission of intelligent bidirectional data between a local end meter reading computer to a user terminal is realized by a new data transmission manner and via a common mobile communication network and low-voltage electric power carrier communication, so as to realize an object of remote controlling and user meter reading. Complementation can be performed between two communications of the common mobile communication network and the low-voltage electric power carrier communication, thereby realizing bidirectional transmission, conversion, transferring of different commnucation mode data. The remote intelligent meter reading system can directly read counting data of user's electric power meter, gas meter and water meter by the local end meter reading computer via a local area network composed of the common mobile communication network, an intelligent data collocting concentrator and the low-voltage electric power carrier communication, and peform remote control on the electric power meter, the gas meter and the water meter.

Description

technical field [0001] The invention belongs to the field of remote intelligent meter reading system. It is a method for remote meter reading, control, and two-way data transmission of electric energy meters, water meters, and gas meters, and a remote intelligent meter reading system formed by the method. Background technique [0002] Data communication is an important link in the remote meter reading system. At present, the remote meter reading system is divided into communication methods, including bus communication (or dedicated line communication), carrier communication, fixed telephone communication, and wireless communication. There are mainly the following methods: [0003] 1. The wired meter reading system is the bus communication meter reading system [0004] One of the wired meter reading methods of electric meters, water meters and gas meters in residential quarters is to use the bus communication method (the commonly used RS485 bus) to form a local area networ...

Problems solved by technology

Large users are using electric energy meters, water meters, and gas meters with GSM wireless network terminals, using the coverage of the existing GSM wireless network and connecting to the server with a GSM modem or GPRS modem to achieve remote automatic meter reading. Purpose, although the construction period and cost are reduced, but due to the high price of electric energy meters, water meters, and gas meters with GSM wireless network terminals, it is difficult to promote and use them in a large area among residential users.

[0012] The above-mentioned methods have limitations in terms of data transmission cost, etc., and to achieve two-way data transmission from the meter reading computer at the local end directly to the user’s meter end, human participation is required in addition to the meter reading system.
