摘　　要：针对现役除湿系统灵活性不能满足装备、存储单元等除湿要求的现状,基于虚拟I2C总线技术设计了灵活性和扩展性优良的温湿度测控系统。系统以单片机为核心,通过虚拟I2C总线采集分布式智能传感器测量的环境温湿度信息,然后进行定量信息融合获得环境准确相对湿度、温度值,按照设定要求驱动空调机、除湿机工作,最终控制环境温度、相对湿度在设定范围内。本温湿度测控系统灵活便于控制、扩展,体现了基于I2C总线构建自动检测系统较传统除湿设备的优越性。To solve the problem that the active dehumidify equipments can＇t meet the demand of military equipments and storages, the software and hardware design of a temperature-and-humidity supervisor system is introduced in this paper. The system, which is single chip, collects both the temperature and the humidity information by intelligent sensors with the virtual I^2C bus, and gets the exact relative humidity value of the environment by means of information fusion. The system starts the air-condition or the dehumidify machine, at the moment, to control the temperature and the relative humidity in the acquired area. The system, which owns good expansibility, is superior to the traditional dehumidify equipments.
