摘要
基于ARM的嵌入式Linux系统,利用Zigbee模块构建近区域无线通信网络,利用GPS模块获取机车的定位信息和速度信息,并用铁路地理信息系统(RGIS)对GPS数据进行修正,构建一个基于RGIS的铁路养护大机机群防碰撞系统。RGIS的使用,可有效提高系统的定位精度,同时提高系统的可靠性和稳定性。
In order to build an anti-collision system for the railway maintenance machines based on the RGIS（Railway Geographic Information System）,we use ARM as the MCU based on the Linux OS,use Zigbee module to build the wireless communication network,use GPS to obtain the location information and the speed of the railway maintenance machines,correction the GPS data with the RGIS.The introduction of GIS is to improve the accuracy of the positioning system,and also to improve the reliability and usability of the anti-collision system.
