The sounding temperature sensor is an important part of the high-altitude image detector. In the face of a complex atmospheric environment, it is not sufficient to only measure atmospheric humidity data and atmospheric pressure data. At the same time, it is necessary to obtain the collected information of the sounding temperature sensor in combination with the current high-altitude environment to achieve three-dimensional space weather data measurement. Aiming at the problems of complicated collection process, low efficiency and large number of terminal equipments existing in the existing manual polling collection methods of temperature sensors, this paper proposes and designs a set of temperature sensor collection system based on multithreading. First, design a complete and reasonable temperature sensor collection process based on the existing equipment. Second, propose a multi-threaded collection strategy to overcome the problems of the current manual round-robin collection mechanism, and then initialize the device, follow the websocket communication protocol, and add an information format judgment mechanism, Complete the stable and accurate transmission of data, and finally realize the automatic prompt function when a terminal device controls 8 thermostats with different temperatures in a stable state, reducing manual participation, improving collection efficiency, and comparing it to find that the current data collection is more stable and the balance state is judged It is accurate and can be used for the deployment of high-altitude image detectors.
