摘要
介绍了一种基于单片机控制的超声波定位车辆行进路线监测系统的构成、工作原理及实现方案,并对系统的性能进行了分析;通过软件查询,实现用一块单片机处理多路接收信号,简化了电路设计,结果表明,该系统可以测量的范围为20 m,精度可达到0.05 m,满足了场地中车辆行进路线即时监测的要求;该系统具有一定的可扩展性。
A kind of vehicle trace monitoring system is introduced based on the control of MCU. It uses the ultrasonic to locate. The framework, principle, realization and the performance of the system are described. It can handle multiplex received signals with one MCU by software query, thereby, the circuit is simplified. The trial showed that the system have the cover range of 20m and the resolution of 0.05m. It also can be applied to some other fields.
