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

Abstract

The invention relates to a remote intelligent meter writing method and a remote intelligent meter writing system, and 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 communication 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 collecting concentrator and the low-voltage electric power carrier communication, and perform 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 systems, and relates to a method for remote meter reading, control and bidirectional 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 and fixed telephone communication, and wireless communication. There are mainly the following types. Way: [0003] 1. Wired meter reading system is bus communication meter reading system [0004] One of the wired meter reading methods for residential users' electricity meters, water meters and gas meters is to use bus communication (the commonly used RS485 bus) to form a local area network ...

Problems solved by technology

Large users are using electric energy meters, water meters, and gas meters with GSM wireless network terminals, and use the coverage of the existing GSM wireless network and the server with a GSM modem or GPRS modem to connect to the network to achieve the purpose of remote automatic meter reading. , although the construction period and cost are reduced, it is difficult to promote the use of electric energy meters, water meters, and gas meters with GSM wireless network terminals on a large scale due to their high prices.

[0012] The above-mentioned methods have limitations in terms of data transmission cost and other aspects, 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.
