无限传感器多边测距，用4边方式定防区机器人的位置，相比卡尔曼算法，是比较粗糙的定位算法-Sensors Unlimited multilateral ranging, set of 4 side of the way the location of the robot defense area, compared to the Kalman algorithm, which is a more rough positioning algorithm

NXP智能车信标组的程序，大致框架已经搭好，算法还未优化.主要问题在于寻找目标的算法识别率不能很高，容易被阳光影响.使用IAR作为开发环境(NXP smart car beacon group procedures, rough frame has been set up, the algorithm has not been optimized)
