基于GPS和RFID技术的铁路信号设备巡检系统

为便于对铁路信号设备巡检人员的管理，结合GPS（卫星定位系统）和RFID（射频识别）技术，设计了一种铁路信号设备巡检系统。它采用GPS技术记录巡检路径，考查巡检人员是否按照规定的路径和顺序检查设备，采用RFID技术考查巡检人员是否检查了某个设备。结合两种技术考查巡检人员开箱检查信号设备时的操作规范性。它将克服基于信息钮扣巡检系统的信息钮扣易受破坏、接触不良的缺点，避免由于GPS／GIS巡检系统的巡检精度低导致无法区分设备的缺陷，同时解决基于RFID的巡检茅统无法进行线路巡检和无法考察巡检人员操作规范性的问题，提高了巡检系统的可靠性。本文介绍了系统设计原理、关键技术的运用及软硬件实现。

A Patrol System for Railway Signal Devices Based on GPS and RFID

To facilitate management of the personnel responsible for the patrolling railway signal devices, a new patrol system was devised by incorporating GPS and RFID technologies. It records the patrol route by GPS, to make sure that the personnel patrol according to the pre-setting route and order. And it can affirm by RFID if the personnel have checked a certain device. GPS and RFID are incorporated to standardization of operation, when a device is opened and checked. This new system overcomes the following deficiencies of the current electronic patrol systems. The iButtons in the iButton-based patrolsystem are easily destoried and hardly read; GPS/GIS based patrol systems have too low patrol precision to differentiate difficiencies of the devices; the RFID based patrol system cannot patrol routes or check normalization of the operation of the patrol personnel. So this new potrol system has better reliability. This paper introduces the design principles, application of key technologies and implementation of hardware and software.
