电气自动化专业毕业论文--高铁接触网补偿装置检测系统通信模块设计.docVIP

摘要 所需要的电能是通过其自带的取电设施(受电弓)与悬挂在铁路上空的输电设备(接触网)滑动接触而取得的，这种相对高度动态的接触取流方式极大地增加了设备状态的不可控性和不可预见性，给电气化铁路正常供电状态的保持带来了巨大的挑战。因此，如何有效的监测接触网的运行状况，及时发现和解决安全隐患，是当前急需解决的问题。(General Packet Radio Service)模块与监控中心通信，具体的通信协议的是本设计的主要内容。 该课题研究的主要内容是研制一种基于GPRS无线通信对接触网的补偿装置运行状态进行在线实时系统。设计包括：通信协议的确定、下位机通信程序的设计与编写、GPRS连接调试。 关键词： 接触网检测 接触网补偿装置GPRS 通信协议Abstract Electric locomotives need to take power through its own facilities (pantograph) by contacting power transmission equipment, hanging over the railway. This relatively high degree of dynamic contact to take flow has greatly increased the uncontrollability and unpredictability of the status of the device, and brings a huge challenge to maintain the normal power supply state of the electrified railway. Therefore, how to monitor the health of the catenary, to discover and resolve security risks is the urgent problem. This design studied a monitoring system of the the catenary compensation device to analyze the status of the catenary operation comprehensively. The design is based on the C8051F020, communicating with the monitoring center through the GPRS (General Packet Radio Service) module.The main content of the design is the specific communication protocol. The main content of this research is to develop status on-line and real-time monitoring system of the compensation device of catenary based on the GPRS wireless communication. The design includes: the determination of communication protocol, the slave machine communication program design and writing and the GPRS connection debugging.
