针对现有减速齿轮箱温度监控系统布线复杂、传输距离短及信号衰减快等缺陷,设计了一套无线自组网齿轮箱温度监测系统,以核心芯片MSP430F149和温度传感器DS18B20进行温度检测,采用射频芯片CC1100模块进行433 MHz无线射频自组网通信,监控软件基于ASP.Net开发,实现对多个齿轮箱的实时温度监测、显示和存储等功能。试验测定传输距离为150 m时,数据丢包率为0%,数据错误率为0.278%,对比传统的监测方式,扩大了监测距离,使齿轮箱的温度监测更加便捷。 Aiming at the shortcomings such as complicated wiring, short transmission distance and fast signal attenuation, the temperature monitoring system of the existing reduction gearbox temperature monitoring system is designed to detect the temperature of the wireless self-assembled gearbox with MSP430F149 and temperature sensor DS18B20. The radio frequency Chip CC1100 module for 433 MHz wireless radio ad hoc network communication, monitoring software based on ASP.Net development, real-time temperature monitoring, display and storage of multiple gearbox functions. When the test distance is 150m, the data packet loss rate is 0% and the data error rate is 0.278%. Compared with the traditional monitoring methods, the monitoring distance is expanded and the temperature monitoring of the gearbox is more convenient.
