Broadband signal transmission system of high-potential environment based on wireless transmission

Abstract

The invention relates to a broadband signal transmission system of a high-potential environment based on wireless transmission, which belongs to the technical field of the high-voltage testing equipment and measurement. The broadband signal transmission system comprises: a sensor which is used for receiving an original signal of a broadband signal to be transmitted and transforming the original signal into a voltage signal; a remote unit which is used for receiving the voltage signal and obtaining a digital signal through analog-to-digital conversion, is connected with the sensor and is arranged in a high-potential environment; a local unit which is used for receiving the digital signal and transmitting the digital signal to a remote computer; and a remote computer which is used for receiving the digital signal from the local unit, displaying the waveform of the original signal received by the sensor, storing the waveform, and completing data storage and analysis. When matched with a proper sensor probe, the signal transmission system of the invention can realize the measurement of physical quantities of the high-potential environment such as the voltage, current, electromagnetic field, power, temperature and the like, and can realize the long-term all-weather online data acquisition and transmission in the harsh natural environment and electromagnetic environment.

Description

technical field [0001] The invention relates to a broadband signal transmission system in a high-potential environment based on wireless transmission, and belongs to the technical field of high-voltage test equipment and measurement. Background technique [0002] There are several outstanding problems in the measurement of high potentials above several kV. First, the potential of the measurement position is high, and the signal transmission of the equipment is difficult; second, the long-term power supply of the measurement equipment is difficult; third, the electromagnetic environment is usually harsh in high potentials. Electromagnetic pulse groups, lightning strikes and operating overvoltages generated by corona discharge may affect the normal operation of electronic systems. [0003] In terms of data acquisition equipment, a lot of research has been carried out at home and abroad, and there are a large number of mature independent devices and boards that can realize broa...
