摘　　要：针对2. 4 GHz频段日益拥挤,易产生同信道干扰等问题,设计了将WSN低功耗802. 15. 4设备(工作在433 MHz频段)和802. 11WiFi设备(工作在2. 4 GHz频段)结合起来的新型系统,既满足了无线传感网低功耗的需要,又确保了数据远距离通信顺畅可靠。其目的是设计并实现一个能自动监测温湿度、PM2. 5、PM10、CO、甲醛等环境信息的智能化系统,用户既可在本地监测亦可远程监测,当各数据超过阈值时通知相应部门采取解决措施。在网络连接方面设有一键配置和自动重连功能。经过测试和使用,该系统无需上位机,功耗低,能实现对无人值守处环境的实时监测,应用前景广阔。Because the 2.4 GHz band are becoming increasingly crowded,and prone to co-channel interference problems,a new system that combines WSN low-power 802.15.4 devices(at 433 MHz band)and 802.11 Wi-Fi devices(at 2.4 GHz band)was designed.It not only satisfied the low power consumption of wireless sensor network,but also ensured the smooth and reliable data communication.The main design goals were to collect environmental information such as temperature,humidity,PM2.5,PM10,CO,formaldehyde and so on,and at the same time to provide real-time monitoring services featuring both local LCD color display and remote data collection.Alarm will be issued when the data exceeds the preset threshold.Smart configuration and automatic re-connection function were implemented.After test and application,the system does not require an upper compute,has low power dissipation.It can realize real-time monitoring of unattended environment and has wide application prospects.
