Remote phase real-time detection method and device

Abstract

The invention relates to a remote phase real-time detection method and device. Principally, a difference value between a rising edge of an X analog signal and a rising edge of a Y analog signal is detected, and a phase difference relation is derived according to the formula that phixy=360*(t1y^-t1x^)*fx, wherein fx represents induction signal frequency, and t1y^-t1x^ represents a time difference between the X analog signal and the Y analog signal. The remote phase real-time detection method and device solve the problems that because wireless communication is applied more and more popularly, particularly, the most commonly used 315 MHz and 433 MHz frequency point modules on the market and traditional direct modulation ASK communication modules are simple and easy to use but are increasingly influenced by the environment, and consequently data in use processes are instable and are prone to be influenced by the outside world; meanwhile, because frequency point adjustment of the modules is unchangeable, particularly, when multiple phasing tester systems are located at the same site, the phasing tester systems interfere with one another and cannot be normally used, and communication distances are short.

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.
