大型望远镜环境温湿度监测系统设计

Design of environmental temperature and humidity monitoring system for large telescope

环境温湿度对大型望远镜的成像质量有非常大的影响。主要论述了大型望远镜温湿度监测系统的设计与实现,该系统采用SI7006-20A作为温湿度传感器,以STM32F103单片机作为处理器,通过CAN总线与上位机组网,实现环境温湿度的测量与显示。系统设计完成后,进行试验验证,结果表明,该系统能够对环境温湿度进行准确监测,可以为主动光学系统中的温湿度补偿与控制提供依据。

The environmental temperature and humidity have a great impact on the imaging quality of the large telescope.The design and realization of the environmental temperature and humidity monitoring system for large telescope are discussed.The system adopts the SI7006?20A as the temperature and humidity sensor,and STM32F103as the processor.The environmental temperature and humidity are detected and displayed by networking the CAN bus and upper computer.The designed system was verified with experiment.The results show that the system can monitor the environmental temperature and humidity accurately,and provide the basis for humiture compensation and control in the active optical system.
