High-precision strong anti-interference temperature measurement system and method

Abstract

The invention discloses a temperature measuring system with high precision and strong interference resistance and a method thereof, and the temperature measuring system consists of temperature sensors and a controlling computer, and is characterized in that the temperature sensors are a plurality of temperature sensors that are respectively arranged on each part of a large-scale astronomical telescope, outputs of the temperature sensors are respectively connected with each temperature survey meter, an analog signal amplifying circuit, an analog-to-digital converter, a data acquisition system,a temperature displaying device and a serial communication circuit are respectively arranged inside each temperature survey meter, which is remotely connected with the controlling computer through the serial communication circuit and the Ethernet. The temperature measuring system adopts the high-precision temperature sensors and temperature survey meters as well as the method that combines hardware with software, thus improving the interference resistant capacity of the system, eliminating power frequency interference and random interference and satisfying the requirement of remote data transmission; simultaneously the temperature measuring system utilizes the Ethernet technique for sampling multi-way temperature data, thus recording and storing measured temperature data in real time and providing reliable foundation for improving astronomical seeing in astronomical observation.

Description

technical field [0001] The invention relates to an astronomical observation auxiliary system and a method thereof, in particular to a high-precision and strong anti-interference temperature measurement system for improving seeing temperature measurement, and a working method of the high-precision and strong anti-interference temperature measurement system. Background technique [0002] The temperature measurement system is an indispensable part of a large astronomical telescope. Because the natural environment parameters inside and outside the telescope observation room have a non-negligible impact on the imaging quality of celestial bodies, especially the ambient temperature gradient is closely related to the seeing degree around the environment, and seeing The deterioration of the temperature will cause the image of the celestial body to flicker, jump or even distort; in addition, there are static electricity, electromagnetic, radio frequency and other interference around t...

Problems solved by technology

At the same time, the current large-scale astronomical telescope has a huge structure, and the distance between the telescope and the control room is long, and the data of the temperature measurement system needs to be transmitted over long distances.

However, there is no high-precision and strong anti-interference temperature measurement system suitable for large-scale astronomical telescopes in the prior art.
