摘　　要：针对当前温湿度远程监测布线复杂、采集速度慢等缺点,提出了一种新颖的分布式无线监测系统。系统由DHT11数字式温湿度传感器、单片机STM32F103和WiFi模块等组成。各采集节点利用STM32F103单片机采集温湿度,然后通过WiFi模块和无线路由器把各采集节点的温湿度参数发送到远程服务器上。试验表明,该系统布线简单、采集速度快、应用灵活,可实现范围分布广泛的温湿度集中可视化监控,具有一定的推广使用价值。Aiming at the disadvantages of current remote monitoring system, e. g. , complex wiring and slow acquisition speed, etc. , a new distributed wireless monitoring system is proposed. The system is composed of DHT11 digital temperature humidity sensor, single chip machine STM32F103 and WiFi module. The temperature and humidity are collected by using STM32F103 single chip machine in each collection node, then, these parameters are transmitted to remote server through WiFi module and wireless router. The experiments show that the system is simple wiring, fast collecting and flexible applying; it can be used in centralized visual monitoring for widely distributed temperature and humidity parameters, and possesses certain values of promotion and application.
