A smart meter data acquisition system with adaptive meter reading strategy and its acquisition method

Abstract

The invention discloses a smart meter data collection system and a collection method of an adaptive meter reading strategy. The system includes several concentrators that communicate with several types of smart meters respectively, and all the concentrators communicate with the server respectively. The concentrators include There is a central processing module with a meter reading module, and a downlink communication module and a storage unit connected to the central processing module. The central processing module also includes an adaptive meter reading strategy optimization module. The storage unit includes a meter reading strategy storage unit for automatic The adaptive meter reading strategy optimization module sets the sampling meter reading time interval for each type of smart meter respectively, and sets the sampling meter reading time interval set by the adaptive meter reading strategy optimization module when all smart meters of the same type of sampling number are successfully copied. The meter reading time interval of the concentrator for the type of smart meter is determined and stored in the meter reading policy storage unit. The invention can greatly reduce the meter reading time of the meter and improve the success rate of reading the meter.

Description

technical field [0001] The invention relates to an intelligent meter data collection system and a collection method of an adaptive meter reading strategy. Background technique [0002] In the current domestic heating metering market, there is a lack of strict unified standards, and there are many meter manufacturers with uneven technical levels. At the same time, the same heating company in the same city often purchases and installs multiple or even multiple models of the same company at the same time due to various considerations. Therefore, in the process of remote unified data collection of heat meters, compatibility with different meters is a very difficult problem. Even if the data protocol is accurate, due to the different processing methods, priorities and CPU operation speeds of different meters when responding to the copy command, there is a huge difference in the time of a single copy for different meters, which can range from hundreds of Between milliseconds and...
