The Design And Development Of Railway Power Supply Panel Online Monitoring System Based On Embedded

Along with the rapid development of our country vigorously promote of the foundation of high-speed railway construction, railway information technology development is very rapid, people’s demand for information is getting more and more high, efficient, clean and pure power is a key factor in the safe operation of the railway. Railway power supply panel is composed of one or more of modular power supply cabinets, a low voltage apparatus and a variety of power electronic components of various power supply module, providing power to the railway station or a station signal equipment of complete sets of equipment is the power of electric locomotive and the heart. The intelligent detection technology is introduced into the power supply, and electronic technology, computer technology is the combination of the technical direction of the future, also after all are applied more and more widely.It is against this background, this paper carefully analyzes the industry norms of the ministry of railways, for monitoring index of railway power supply panel, after full investigation and hardware selection, considering cost, reliability, stability, temperature drift and so on various factors. Build a monitoring, summary, statistic, display and warning system. The design of the system is divided into three layers architecture, front is the sensing layer, the second is to control the floor, the third layer is data summary analysis. According to the Modbus protocol to communicate between each layer.After testing, the system has good man-machine interface, on the basis of embedded operating system platform, has realized the system requirements mentioned in the indicators. Data acquisition unit, communication unit, RTC unit, man-machine interface unit, storage unit, sound and light alarm unit are working properly, and data acquisition is accurate. The logic of operation is reasonable. Achieve the expected goal.
