粮库粮情监测系统研制

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。

The Monitoring System Development for Grain Situation

In this paper, developed a set of grain monitoring system for grain situation, can monitor the temperature of the grain food, at the same time, this system had wireless rf module and reserved RS485 interface, can access other wired or wireless sensors, monitored environmental temperature and humidity within the grain depot, grain moisture content, gas （02, CO2, PH3） and other physical quantities. This system included temperature t cables, wireless data concentrator and wireless temperature measuring rod. Temperature measuring cable and wireless temperature measuring rod embedded in DS18b20 sensors,all DS18b20 sensors connected to the wireless data concentrator through single bus. Wireless data concentrator was data forwarding device was also a data acquisition device. The equipment would be monitoring of grain situation of equipment acquisition data transmission through GPRS or Ethernet to remote monitoring host.
