A wireless data transmission method and system for heat meter control

Abstract

The invention relates to a wireless data transmission method and system for heat meter control. A wireless communication technology is adopted for a concentrator to achieve data collection / data downloading between an upper computer and a heat meter, and a transmission path of wireless signals is dynamically changed in due time so that the problems that wirelessly-transmitted signals are largely influenced by the environment, and it is difficult to directly receive data communication signals of all wireless heat meters in a whole building (or a corridor unit) with one wireless data concentrator can be solved. According to the method, the functions of automatic recognition and automatic routing are achieved, and the method has good market prospects on the aspect of wireless data meter reading.

Description

technical field [0001] The invention relates to a wireless data aggregation method, in particular to a wireless data aggregation method and system for a heat meter system capable of realizing remote collection of heat meter data. Background technique [0002] The data aggregation method is an important method of the remote heat meter reading system. It is a key technology for the concentrator to realize data collection / data download between the host computer and the heat meter. It carries the information collected from the heat meter and uploaded to the host computer. important task. At present, domestic concentrators mainly adopt M-BUS bus technology, and use twisted pair or telephone lines to carry out wired transmission and concentration of all user heat meter data in a building, that is, a wired data aggregation method. [0003] The advantages of the existing wired data aggregation method are that the signal transmission of the wired method is stable, the signal transmi...

AI Technical Summary

Problems solved by technology

[0003] The advantages of the existing wired data aggregation method are that the signal transmission of the wired method is stable, the signal transmission is less affected by environmental factors, and the installation position of the concentrator in the building is not high, but the wired method also has many disadvantages, such as large construction costs. , high cost of line maintenance, difficulty in refitting old buildings, etc.

[0004] However, the indoor wireless signal transmission of wireless heat meters is greatly affected by environmental obstacles, and the signal attenuation is relatively large, which leads to the inability to collect the data of wireless heat meters that are a little far away from the wireless data concentrator, and it is difficult for a wireless data concentrator to directly receive data in a building. (or in a corridor unit) data communication signals of all wireless heat meters, of course, increasing the transmission power can increase the communication distance, but it is still difficult to overcome the above problems due to factors such as limited transmission power, obstacles, wireless interference in specific areas, etc.
