| In this thesis, low voltage electrical energy collection system as the background ofthis actual project, based on uC/OS-II operating system for embedded carrier meterconcentrator and collector as a research goal. With the " TOU " and " a form of "supplymanagement needs arising from the core issue of remote meter reading system is thetransmission and processing of data; With intelligent management improvement in thelevel of social, national and local grid the introduction of a series of managementstandards, the company’s existing products difficult to continue to adapt to newdemands and new standards. In addition, the existing product technology is relativelybackward, backward technology while increasing the cost of production and furtherdevelopment. In order to reduce the cost of projects, and enhance marketcompetitiveness, to better provide customers with a variety of reliable low voltage meterreading program, so that my company ’s reading system to better adapt to differentmarket needs, the introduction of the national grid to meet the latest focus meterspecification. We introduce new technologies, the master chip ST has introduced a newkernel based on ARM Cortex-M3microcontroller STM32, downlink carrier meterreading module is developed using Qingdao Neusoft stable carrier meter readingmodule, developed a new generation of centralized controller and acquisition, and thendevelop a new generation of carrier meter reading system that is based on an embeddedoperating system carrier meter reading system. The carrier meter reading system notonly meets the latest national grid on information collection system concentrator(collector) type specifications and functional requirements of the Statute of the other698, and the meter reading system in order to improve the efficiency and reliability ofthe system even more attention research on non-functional needs, that more attentionreliability, real-time, data security, stability and other systems of communication. |
