摘　　要：为了提高移动机器人的定位能力,提出了一种测障系统。硬件电路以STC12C5A60S2单片机为主控核心,外围电路主要由超声波测距、电子罗盘测方位、数字测温和液晶显示电路组成。测距由超声波渡越时间法实现,利用所测温度实时修正参数,提高了测距精度。方位由电子罗盘采集并以数字量输出,简化了电路。系统软件是一个微内核、多任务的实时系统,将μC/OS-Ⅱ嵌入单片机,多参数采集程序运行之上,弥补了前后台系统处理多参数实时性差的不足。实际运行表明,系统具有测试精度高、实时好和扩展性好等优点。In order to locate accurately for mobile robot, this paper presented a kind of obstacle detection system based on STC12C5A60S2 MCU. The peripheral circuit is composed of the ultrasonic circuit for measurmeng distance from barriers, the elec tronic compass for direction angle acquisition, digital thermometer and clock chip.With features of microkernel, multitasking and re al time, the application program runs with embedded IC/OSI. The actual operation shows that tile system significantly improves accuracy, real time and expansibility.
