一种无线超声波水位仪
摘要：
本发明公开了一种无线超声波水位仪，包括：超声波探头模块，用于将电脉冲信号转为超声波信号向外发送，并接收返回的超声波信号；超声波信号处理模块，用于产生一定频率的脉冲信号并发送至超声波探头，以及对接收到的超声波信号进行处理；微控制器模块，用于控制超声波探头模块超声波信号的发送与超声波信号处理模块的超声波信号处理，以及根据处理后的超声波信号计算水位高度；无线数据收发器模块，用于将微控制器模块计算出的水位高度通过无线的方式向外发送，以及将外部发送的超声波探头模块与超声波信号处理模块的工作参数数据转发给微控制器模块。本发明公开的无线超声波水位仪，可省去了前期繁琐的布线过程，且节省了成本。
摘要（英）：

The invention discloses a wireless ultrasonic water level instrument. The wireless ultrasonic water level instrument comprises an ultrasonic probe module for converting an electric pulse signal into an ultrasonic signal to be sent to the outside and receiving a returned ultrasonic signal, an ultrasonic signal processing module for producing and sending a certain-frequency pulse signal to an ultrasonic probe and processing the received ultrasonic signal, a microcontroller module for controlling ultrasonic signal sending of the ultrasonic probe module and ultrasonic signal processing of the ultrasonic signal processing module and calculating the water level height according to the processed ultrasonic signal, and a wireless data transceiver module for outwards sending the water level height calculated by the microcontroller module in a wireless mode and forwarding outwards sent working parameter data of the ultrasonic probe module and the ultrasonic signal processing module to the microcontroller module. The wireless ultrasonic water level instrument can omit earlier-stage complicated wiring process and save the cost.
