研制了一套粮库粮情监测系统,可以监测粮库粮堆内的温度,同时,系统自带无线射频模块和预留RS485接口,可以接入其它有线或无线的传感器,监测粮库内环境温湿度、粮食水分、气体(O2、CO2、PH3)等物理量。系统包括测温电缆、无线数据集中器及无线测温杆。测温电缆和无线测温杆内嵌入的所有DS18b20传感器通过单总线与无线数据集中器连接。无线数据集中器既是数据转发装置亦是数据采集装置,它将粮情监测设备测取的数据通过GPRS或以太网传输至远程监控主机。
Developed a grain depot food condition monitoring system, which can monitor the temperature inside the grain depot. At the same time, the system comes with RF module and reserved RS485 interface, which can access other wired or wireless sensors to monitor the environment inside the grain depot Temperature and humidity, food moisture, gases (O2, CO2, PH3) and other physical quantities. The system includes temperature measuring cable, wireless data concentrator and wireless temperature measuring rod. All DS18b20 sensors embedded in the temperature sensing cable and wireless temperature probe are connected to the wireless data concentrator via a single bus. Wireless data concentrator is both data forwarding device and data acquisition device, it will be the grain monitoring equipment to measure the data transmitted via GPRS or Ethernet to the remote monitoring host.
