新型粮仓多点无线测温系统

Multipoint Wireless Temperature Measureing System for Granary

为实现粮仓内温度的自动监测与控制,采用单总线测温器件DS18B20对每个仓房间隔进行多点测温,由CC2430组成的Zigebee无线发送模块把温度信息发送至仓房总测温模块,仓房总测温模块与监控中心通过RS485连接起来.当检测到温度越限时自动启动通风风机,达到了自动检测温度和控制温度的目的.通过实际测试验证了本系统的稳定性和可靠性.

To realize automatic monitoring and control of granary temperature, multipoint temperature is measured in each warehouse by using single bus measuring temperature device DS18B20, and the Zigebee wire- less transmission module composed by CC2430 sends the temperature information to the warehouse total tempera- ture measurement module, which is connected with the monitoring center warehouse RS485. The fan will auto- matically start when the temperature exceed setting limit, so the purpose of automatic detection and control tem- perature is realized. The stability and reliability of the system are verified by the practical test.
