Multi-parameter measurement system based on remote power supply and wireless data transmission

Abstract

The present invention discloses a multi-parameter measurement system based on remote power supply and wireless data transmission. The system comprises a remote measurement unit and a ground transmission and receiving unit; the remote measurement unit comprises a solar panel arranged at a far end, a focusing lens, an input fiber optics bundle, an output fiber optics bundle, a sensing head, a photoelectric detector, a drive circuit and a wireless emission unit; the ground transmission and receiving unit comprises a laser, a control circuit and a wireless receiving unit, the laser is incident facing the solar panel and the focusing lens, and the control circuit controls the wireless receiving unit to receive measurement data emitted by a wireless transmission unit. The multi-parameter measurement system employs a ground laser to irradiate a high-altitude solar panel to achieve power supply of a remote sensing head and a detector, reduce the noise of the measurement unit, manually controlthe power supply time and facilitate structure miniaturization of the measurement system.

Description

technical field [0001] The invention belongs to the technical field of sensing and measurement, and relates to a measurement system for laser solar battery power supply and data wireless transmission. Background technique [0002] In the development and technical development of high-voltage transmission network and pulse power equipment, it is necessary to monitor the parameters of high-voltage transmission equipment and pulse power source, such as the temperature of certain components, output voltage, and the liquid level of oil in the internal transformer. , to reflect whether the monitored object is normal. Since these devices are all high-voltage devices, in order to prevent the sensor itself from affecting the electrical output of the device and high-power high-voltage devices from affecting the sensor measurement, active optical fiber sensors are often used to measure its parameters, such as transformer oil level height Both sensors and temperature sensors need to int...

Problems solved by technology

Since these devices are located in the field at a height of more than ten meters to tens of meters, the ambient temperature range is large, and the power supply and data collection of the sensors are inconvenient to operate. It is urgent to carry out new measurement technology research and measurement system development to solve its practical application problems.
