Efficient wireless meter reading method for automatic network router

Abstract

The invention discloses an efficient wireless meter reading method for an automatic network router. The router comprises a concentrator serving as a primary node and a collector serving as a secondary node. Firstly, one communication network can have only one primary node, and each primary node may have 255 secondary nodes; in the same wireless network, each node has an unique communication address of which value ranges from 0 to 255; the primary node ID is 0, while the secondary node ID ranges from 1 to 255; secondly, wireless data transmission modules arranged on the primary node and the secondary node are provided with a plurality of optional channels, a communication channel is required to be adjusted under both two conditions; and thirdly, the primary node acquires all communicable secondary nodes by an automatic route method, and acquires relay paths to all secondary node so as to realize the wireless meter reading. The invention can improve the application performance of a meter reading system and fulfill the aims of convenient construction, free debugging and less maintenance.

Description

technical field [0001] The invention relates to a wireless meter reading method, in particular to a wireless meter reading method with efficient network automatic routing. Background technique [0002] The wireless remote meter reading control system is an application project suitable for the implementation of intelligent residential quarters in my country. It has changed the traditional charging method of manual meter reading, and realized the computer automatic metering and charging of various residential energy consumption parameters (water, electricity, gas, heat, etc.), satisfying the owner's "privacy" and "safety" of living It also provides a good foundation for improving the modernization level of property management and even industry management. [0003] The wireless meter reading system is generally composed of four parts: the management center computer, the concentrator, the collector, and the meter terminal, such as figure 1 Architecture diagram of wireless remo...

Problems solved by technology

But it greatly increases labor costs, such as low efficiency and error-prone input list, cumbersome addition, deletion, and mobile nodes, and frequent maintenance and updates

[0007] In the invention patent with the patent number "01136618.4" and the patent name "Automatic Routing Method for Wireless Meter Reading System", it actively searches for reliable connection node addresses through the slave node competition channel, and the efficiency is relatively low. 1. Each slave The node will act as the master node to actively search, with a large amount of repetitive work

2. Each node will save an address list, which has a large amount of redundancy

3. From the start of the search on the master node to the final collection of all the lists, the time is uncontrollable

4. Channel competition, there is a probability of multiple nodes sending at the same time, which will cause conflicts

5. If there are different networks in a local area, the interference cannot be resolved
