Research On Micro-power Wireless Communication Interconnection Test System

Micro-power wireless is more and more widely used in the electricity information network of data because of its characteristics of low power consumption and flexible networking, and it has become the important part of the information collection and transmission link.Micro-power wireless often could not be unalbe to communicate normally, there are some problems in judging its communication quality, which has brought tremendous pressure to the production enterprises. The detection of the traditional way only can detect whether it is online and work successfully or not.The tranditional detection can not Analysis and validate the quantitative and qualitative communicaiton quality.In view of the above situation, the main performance parameters of the micro power wireless communication module must be tested unifiedly according to the national grid related standards and technical norms, which detect and evaluae the the interconnection performance. In this way we can improve the the stability and reliability of the electric information acquisition system,which is very important to achieve the "full coverage, full collection, full cost control" target.This paper research on the measurement technology of micro power wireless communication,which make the test scheme of micro power wireless communication, complete the automatic test of its wireless communication combining with test instruments and instrument control technology.Mainly completed the following work:1. Analyze and establish the related indicators of micro-power wireless communication,which based on wireless communication test of the smart meter performance.This paper formulate the basic system test plan based on the study of the micro power wireless communication protocol.2. This paper design the testing system according to the existing equipment and testing specification,analysis and related test index through the study on test instrument and build test concrete system environment with the appropriate components.3. Participate in the work of the micro power wireless communication transmission channel model establishing.This paper establish the propagation model of micro-power wireless transmission.This model would effectively help us analyze the basic situation of micro power wireless electric signals acquisition system in the interior transmission, which contribute to the deployment planning of urban district of micro power wireless meter reading system.
