【摘要】：微功率无线以其低功耗、组网灵活等特点,在用电信息数据传输网络中,愈加广泛应用,逐渐成为信息采集和传输链路中重要的部件或单元之一。微功率无线通信在现场实际应用中,经常出现无法正常通信、故障点不好判断的问题,这种情况给生产企业带来了巨大压力。传统的检测方式只能检测上线是否成功、数据能否正常交互,无法对通信质量进行定量和定性的分析验证。针对上述情况,对微功率无线通信模块的主要性能参数,按照国家电网相关标准和技术规范,进行统一测试,从而对其指标以及互联互通性能进行检测和评估。以便有效提高用电信息采集系统的稳定性、可靠性和可扩展性。本课题研究微功率无线通信的测试技术,制定了微功率无线通信相关性能的测试方案,结合测试仪器以及仪器控制技术来完成对其无线通信指标的自动测试。主要完成了以下工作:(1)分析确立了智能电表微功率无线通信性能测试的相关指标,研究了微功率无线通信的相关协议,制定了系统的测试方案。(2)。通过对于有关测试仪器的研究,以及相关测试指标的分析,设计了微功率无线通信网络测试评估系统和微功率无线通信单元测试系统(3)针对微功率无线多用于的室内传输情况,建立了室内传输模型。该模型可有效的分析用电采集系统中的微功率无线信号在室内传输的基本情况,有助于以后城市台区微功率无线抄表系统的部署规划。
[Abstract]:Because of its characteristics of low power consumption and flexible networking, micro-power wireless has become one of the most important components or units in the information collection and transmission link, which has become more and more widely used in the electrical information data transmission network. In the practical application of micro-power wireless communication, the problem of unable to communicate normally and difficult to judge the fault point often occurs, which brings great pressure to the production enterprise. The traditional detection method can only detect whether the line is successful or not, whether the data can interact normally, and can not analyze and verify the communication quality quantitatively and qualitatively. In view of the above situation, the main performance parameters of the micro-power wireless communication module are tested in accordance with the relevant standards and technical specifications of the State Grid, so as to detect and evaluate the performance of the micro-power wireless communication module and the connectivity performance. In order to effectively improve the stability, reliability and extensibility of the power information collection system. In this paper, the testing technology of micro-power wireless communication is studied, and the test scheme of micro-power wireless communication performance is established. The test instrument and instrument control technology are combined to complete the automatic test of the wireless communication index of micro-power wireless communication. The main work of this paper is as follows: (1) analyzing and establishing the performance test index of intelligent watt-hour meter micro-power wireless communication, researching the correlative protocol of micro-power wireless communication, and making the test scheme of the system. Based on the research of the test instruments and the analysis of the related test indexes, a micro-power wireless communication network test evaluation system and a micro-power wireless communication unit test system are designed, which aim at the indoor transmission of micro-power wireless. The indoor transmission model is established. This model can effectively analyze the basic situation of indoor transmission of micro-power wireless signal in electric power acquisition system, and help to plan the deployment of micro-power wireless meter reading system in urban area.
