Network Data Exchange Method for Remote Meter Reading of Gas Meter

Abstract

The invention discloses a gas meter remote meter reading network data exchange method. A starting terminal issues a burst communication command to a target terminal according to a routing table stored by it itself, or communicates with the target terminal through a relay node, the target terminal returns a feedback response signal according to an original routing link and carries out response operation, and then returns the execution result information according to the original routing link. The leading synchronous code involved in the invention is a baker code with autocorrelation characteristics, and baker codes of different digits are employed to represent different burst communication command types so as to wake up corresponding devices of the target terminal and execute corresponding text instructions, thus effectively lowering the power dissipation of a gas meter. The method provided by the invention solves the fixed start, synchronous single format and other problems in existing communication, can resist the interference of non-home network communication signals, overcomes the influence of environmental factors, and has the advantages of low communication date error rate, far transmission distance and high communication efficiency, and is more energy-saving and low consuming.

Description

technical field [0001] The invention relates to the field of meter reading of gas meters, in particular to a data exchange method for remote meter reading networks of gas meters. Background technique [0002] As we all know, natural gas is an indispensable necessities of life for every family, and it is directly related to the interests of the country and people's property. With the changes in people's lifestyles, the problem of "difficult to read meters at home" has become increasingly prominent. The method of manual meter reading by meter readers on a monthly basis is not only time-consuming and laborious, but also the accuracy and timeliness of meter reading data cannot be guaranteed. It also involves many issues such as user privacy, security, timeliness, and high work intensity of meter reading personnel. How to timely and accurately collect and recover data from gas meters scattered in different places is the most important part of the entire operation of a gas supply...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art, provide gas meter remote meter reading network data exchange method, to solve the fixed start of existing communication, a single format of synchronization, it can not only resist the interference of non-network communication signals, but also It can overcome the problems of high communication data error rate and short transmission distance caused by environmental factors
