Description: 超声波测距电路图。至于为什么接收不用晶体管做放大电路呢，因为放大倍数搞不好，CX20106集成放大电路，还带自动电平增益控制，放大倍数为76dB，中心频率是38k到40k，刚好是超声波传感器的谐振频率，感觉很合适。-Ultrasonic Distance Measurement circuit. As for why the receiver do not have to do the transistor amplifier circuit, because magnification well, CX20106 integrated amplifier, but also with automatic level gain control, magnification to 76dB, the center frequency is 38k to 40k, is exactly the resonant frequency of ultrasonic sensors, feel is appropriate.

Description: 超声波测距原理
超声波测距是通过不断检测超声波发射后遇到障碍物所反射的回波,从而测出发射和接收回波的时间差t,然后求出距离S=Ct/2,式中的C为超声波波速。 -Ultrasonic Distance Measurement Ultrasonic Distance Measurement principle of continuous detection of ultrasound through the encounter after the launch of the echo reflected from obstacles in order to detect the launch and receive the echo time difference t, and then calculated the distance S = Ct/2, the C-type for the ultrasonic wave velocity.

Description: 介绍了利用微处理机控制单元(MCU microprocessor control unit) 控制的超声测距仪的原理:由MCU 控制时间计数,计算超声波自发射至接收的往返时间,从而得到实测距离。给出了系统构成、电路原理及程序设计。并且在数据处理中采用了温度补偿和修正量的调整。此系统具有易控制、工作可靠、测距准确度高和流程清晰等优点。-Abstract : Principle and structure of ultrasonic distance measurement instrument by master of MCU are intro2 duced. With the control of MCU to operate the time2keeping ,distance from target to original point is gained using product with the time of ultrasonic transmitting both to the target and reflecting back and the speed of ultrasonic which transmits in the air. And system structure ,circuit philosophy and programming are also specified. In the process of data , temperature compensation and adjustment of amendment ammount are used , so the instrument system has features : ease of control , stability of operation , highness of precision and distinctness of programme process ,etc.
