摘要
本文介绍了一种可以克服长距离干扰的信号遥测新方法。这种方法在设备端通过电压频率转换将信号转换成频率与信号幅值成比例的适合远距离传输的脉冲波,在测试室通过频率电压转换电路还原该信号。文章给出了信号遥测的电路设计。应用结果表明,该设计达到了测试要求,适合于所有需要信号遥测的慢变系统。
This paper introduced a new method to realize remote signal measure, which can reduce the interference due to the long distance transmission. The method changes signal into a series of pulse, whose frequency is proportional to signal＇s amplitude, through VFC circuit on the end of UUT. At the test chamber, the FVC circuit resumes the signal. In the paper, the practical scheme based on LM331 to realize the new method is put forward. The result of application shows the new method fully meet the test demand and suitable to all slowly change systems with a need of remote measure.
