Problems solved by technology

However, the existing communication processing method adopts the method that the concentrator as the master node polls the gas meter as the slave node for data transmission; such a master-slave polling communication mode makes the wireless gas meter Always in receive state, waiting for concentrator's poll
As we all know, in a wireless gas meter, the module responsible for wireless communication is the largest power consumer in the gas meter, and the wireless communication gas meter is generally powered by a DC battery, and the stored energy is limited. The wireless communication module in the gas meter is powered, which greatly shortens the service life of the DC battery and restricts the popularization and application of the wireless gas meter; It is very busy, so that the wireless gas meter cannot send the information in the gas meter to the concentrator in real time, so that it cannot realize the real-time monitoring of the user's gas consumption, and cannot provide relevant useful information for the gas management department

Embodiment Construction

[0007] The communication processing method of the gas meter described in the present invention is based on the master-slave topology network structure of a master node sharing a channel to a plurality of slave nodes. In this embodiment, a master node communicates with 250 slave nodes. Point-to-multipoint wireless communication, and it is assumed that every time 1 cubic gas is consumed, the slave node will report data once; when every 1 cubic gas is consumed, the slave node will actively contact the master node, and if the channel is busy at this time, it will wait The channel is idle, and then send information data packets to the master node, the master node analyzes the received information data packets, and judges whether to communicate with the master node, if not, discards the information data packets, if so, calculates and compares the check code , the result is wrong, then the communication failure response data packet will be downloaded, and the slave node will resend th...

Abstract

A fuel meter communication handling built on a major node of a shared channel forming master-slave typological network structure, features in the connection and exchange of data starting form the node fuel meter based on preset conditions and accumulator as the main node, it can greatly reduce the occupation rate of the following node to the channel, reduces the communication waiting time and energy consumption, and improve the endurance of the battery from the node.

Description

technical field [0001] The invention relates to a wireless communication processing method, in particular to a wireless communication processing method of a gas meter. Background technique [0002] At present, commonly used gas meters include traditional gear-type mechanical gas meters, IC card gas meters and wireless gas meters. The traditional gear-type mechanical gas meter requires a lot of manual meter reading, the workload is very large, and human errors often occur; for IC card gas meters, since user information is stored on the IC card, it is easy to be stolen. Gas, gas stealing and other phenomena, and after the IC card is lost, it is very troublesome to replace the card and replenish the gas. The emergence of wireless gas meters, data transmission through wireless communication, instead of manual meter reading and exchange of signals with IC cards, should be said to represent the future development direction of gas meters. However, the existing communication proce...
