超声测距技术在工业现场、车辆导航、水声工程等领域都具有广泛的应用价值，目前已应用于物位测、机器人自动导航以及空气中与水下的目标探测、识别、定位等场合。因此，深入研究超声的测距理论和方法具有重要的实践意义。
系统介绍了硬件和软件两个方面。系统的硬件设计与实现经过综合考虑和选择，本次设计方案选定使用STC12C2052作为主控制系统；测距模块根据Trig和Echo发送和接收的数据经过单片机，计算出距离。电路中还要有显示部分，采用数码管显示。当测的距离到达指定距离，对应的led亮，达到报警距离时蜂鸣器响。
本设计采用通用原件，成本低、实用性强、性能可靠、性价比高，使用方案简单。

Answer 1

你好。
Ultrasonic distance measurement technology in the field of industrial field, vehicle navigation, underwater acoustic engineering has extensive application value. Now it has been used in level measurement, robot automatic navigation and air and underwater target detection, identification, location and other occasions. Therefore, it is very important to study the theory and method of ultrasonic distance measurement.

Two aspects of hardware and software are introduced in this paper. The hardware design of the system and implementation after comprehensive consideration and choice. This design scheme is selected using stc12c2052 as the main control system; ranging module according to trig and echo to send and receive data through the MCU, calculate the distance. The circuit also has a display part, the use of digital tube display. When the distance reaches the specified distance, the corresponding LED is bright, and the alarm is reached when the alarm distance is reached.

This design uses the general original, the cost is low, the utility is strong, the performance is reliable, the cost is high, the use plan is simple.

Key words: ultrasonic; distance measurement instrument; single chip microcomputer
