A kind of remote phase real-time detection method and device

Abstract

The present invention relates to a long-distance phase real-time detection method and device, mainly by detecting the difference between the rising edges of X / Y two-way analog signals, and deducing the phase difference relationship according to the formula φxy=360*(t1y^‑t1x^)*fx , where fx is the frequency of the induction signal, and t1y^-t1x^ is the time difference between the X / Y analog signals. The invention solves the problem that since wireless communication is more and more widely used, especially the most commonly used 315MHz and 433MHz frequency point modules on the market, the traditional direct modulation ASK communication module, although simple and easy to use, is more and more affected by the environment, resulting in The data in use is unstable and easily affected by the outside world. At the same time, because the frequency point adjustment of the module remains unchanged, especially when multiple sets of phase nuclear instrument systems are in the same site, they interfere with each other and cannot be used normally, and the communication distance is short, etc. question.

Description

technical field [0001] The invention relates to the field of electrical test equipment, in particular to a method for long-distance phase detection and a phase nuclear instrument device. Background technique [0002] The traditional remote phase real-time detection mode uses the ASK modulation and demodulation module to realize the remote real-time transmission function of phase information, but because wireless communication is more and more widely used, especially the most commonly used 315MHz and 433MHz frequency point modules on the market, the traditional direct modulation ASK Although the communication module is simple and easy to use, it is more and more affected by the environment, which leads to unstable data in use and is easily affected by the outside world. At the same time, because the frequency point adjustment of the module remains unchanged, it is especially suitable for multi-set nuclear phase instrument systems. There are many problems such as mutual interf...

[0002] The traditional remote phase real-time detection mode uses the ASK modulation and demodulation module to realize the remote real-time transmission function of phase information, but because wireless communication is more and more widely used, especially the most commonly used 315MHz and 433MHz frequency point modules on the market, the traditional direct modulation ASK Although the communication module is simple and easy to use, it is more and more affected by the environment, which leads to unstable data in use and is easily affected by the outside world. At the same time, because the frequency point adjustment of the module remains unchanged, it is especially suitable for multi-set nuclear phase instrument systems. In the same site, there are many problems such as interference with each other, resulting in failure to use normally, and short communication distance.
