Abstract As the national economy and the power industry continue to develop rapidly, the implementation of one household, one meter system has become almost universal. Enterprise-level power load monitoring and control systems have been put into use in some areas, achieving good results. However, due to the large number of low-voltage electricity users and their wide geographic distribution, the workload of power companies for meter reading is substantial. Therefore, using new technological means and local and remote automatic meter reading technology to achieve automatic meter reading and real-time monitoring of electricity meters are of great importance. This would reduce the labor of manual meter reading and data input, and improve work efficiency, truly achieving automatic management of electricity usage. Therefore, the remote centralized meter reading system has become a choice for power companies to solve meter reading problems. This paper aims to provide a low-cost, high-reliability technical application for achieving the automation of public utility billing and the intelligent management of community property using low-voltage power supply networks. It discusses the design of the data collector and data concentrator, and analyzes the characteristics of low-voltage power line networks. Based on the analysis of the basic principle of spread spectrum communication, a detailed introduction of the specific implementation scheme of the power line carrier remote meter reading system, including hardware modules and management software, is provided. Keywords: Low-voltage power line network, centralized meter reading, concentrator, remote meter reading.
