Embodiment Construction

[0021] First purpose of the present invention is achieved by the following methods:

[0022] An intelligent remote meter reading method. Its data transmission is realized through the public mobile communication network (GSM network) and low-voltage power carrier communication, which is divided into two layers of network structure, the upper layer and the lower layer. The functions of bidirectional data transmission, conversion and forwarding of data in different communication modes between the two layers of networks are realized by the intelligent data collection concentrator in the present invention.

[0023] The data transmission of the upper layer network is carried out two-way data transmission with more than one intelligent data collection concentrator 4 through the public mobile communication network (GSM network) 3 and one or more intelligent data collection concentrators 4 by the local end meter reading computer 1 equipped with the wireless modem (GSM modem) 2 . There...

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...
