摘要
本文提出一种重量信号的无线传输和测量方法，重量信号经传感器转换成电信号，再经V／F交换后调频发射，接收信号解调后送单片机处理，单片机的信号处理采用电子计数器测频方法，经过计算送显示单元，实现重量信号的遥测。
A wireless transmission and telemetering method for weight signal is suggested in this paper. The weight signal is first coverted into electronic signal through transducer,and then the electronic signal is converted into frequancy signal through V/F converter.The frequancy signal is modulated and transmited. The single chip computer system receives the demodulated signal and calculated the weight with digital signal processing methods. The result can be displayed at last.
