摘　　要：在大口径望远镜主镜成像中,温度和湿度变化是影响成像质量的参数之一,为了监测大口径望远镜主镜的温度和湿度变化,提高望远镜成像质量。设计了一种温湿度监测系统,采用数字高精度芯片SHT25作为温湿度传感器,以STM32F042单片机作为核心处理器,采用I^2C接口采集温湿度传感器的温湿度数据,采用CAN总线方式进行数据传输,上位机用LabVIEW软件开发的虚拟界面进行数据显示。设计完成后,进行多节点数据采集,经实验验证,结果显示,该系统能够准确监测温湿度数据。Temperature and humidity changes are one of the parameters that affect the image quality in the imaging of the main mirror of large-caliber telescope. In order to monitor the temperature and humidity changes of the main mirror of large-caliber telescope and improve the image quality of the telescope. A temperature and humidity monitoring system is designed. Digital high-precision chip SHT25 is used as the temperature and humidity sensor, STM32 F042 MCU is used as the core processor, I^2C interface is used to collect temperature and humidity data of the temperature and humidity sensor, CAN bus is used for data transmission, and the host computer USES the virtual interface developed by LabVIEW software for data display. After the design is completed, the multi-node data collection is carried out. The experimental results show that the system can accurately monitor the temperature and humidity data.
