摘要
射频车辆定位系统的核心技术和难点问题是车辆定位的算法和协议,针对目前射频定位系统的数据碰撞问题,对传统的射频时隙算法进行改进,提出一种改进型二叉树型算法。射频定位系统上位机采用IFIX组态软件编写,结合VB和Matlab编写的曲线拟合控件,可以查询车辆运行历史轨迹,实时监控井下车辆的运行状态,记录车辆违规的信息并报警,所有车辆运行信息储存到SQL数据库中。
The key technology and difficult problem of radio frequency vehicle positioning system is the vehicle positioning algorithms and communication protocols, in view of the present RFID position system data collision problem, the paper makes some changes in the traditional slot algorithm, puts forward a kind of improved binary tree algorithm. The host computer software of radio frequency positio- ning is designed by IFIX configuration software, combined with curve fitting activex designed by VB and Matlab, the vehicle running history can be queried in the software, and the running state of the vehicle can be monitored to record the vehicle violation information and alarm in real -time. All vehicle operation information are stored in SQL database.
