The invention relates to a device, system and method for measuring temperature by contacting the surface of a moving target in a vacuum low-temperature environment, wherein the device includes: a plurality of temperature sensors arranged on the moving target inside the vacuum tank; a wireless collection terminal arranged inside the vacuum tank In the motion simulation mechanism, and the wireless collection terminal is connected with the temperature sensor, used to collect the signals of the multiple temperature sensors, generate temperature data through analog-to-digital conversion, and send it wirelessly; the first antenna is installed on The motion simulation mechanism inside the vacuum tank is connected to the wireless collection terminal for sending the temperature data. The present invention adopts wireless transmission and reception in the space environment simulation system to obtain the real-time surface temperature measurement data of the moving target inside the vacuum tank, compared with the data transmission using the reflux ring in the prior art, it ensures the stable and accurate transmission of the temperature data .
Description
technical field [0001] The invention relates to the technical field of vacuum low temperature environment simulation, in particular to a contact temperature measuring device, system and method for a moving target surface in a vacuum low temperature environment. Background technique [0002] In the vacuum low temperature environment simulation system, the measured target is usually installed on the motion simulation mechanism inside the vacuum container. When conducting simulation experiments, it is usually necessary to measure the temperature of the moving target surface in real time. When measuring the surface temperature of a moving target, due to the continuous rotation of the target, the signal of the temperature sensor is usually transmitted to the outside of the container in the form of a return ring in the prior art, but the performance of the return ring in a vacuum and low temperature environment is difficult to guarantee the data. Stable and accurate transmission....
