摘　　要：提出一种基于ZigBee无线通信技术的低功耗轴承温度检测系统设计方案。通过数字化温度传感器DSl8820检测轴承温度,应用Jennic公司JN5139模块构建ZigBee无线系统,并利用其内部电源监控电路检测电压。重点介绍数据采集节点的软硬件设计和系统低功耗实现方案。经测试与实验表明,系统工作稳定可靠,持续工作时间可达半年。The low power detection system design solution for bearing temperature based on ZigBee wireless technology is proposed in this paper. The system collects bearing temperature data via DS18B20 temperature sensor. The JN5139 module of Jennie company is used to design ZigBee wireless system. The internal supply monitoring circuit of JN5139 can measure the analogue supply voltage. The software and hardware design for data acquisition node and low power application are the focus of this paper. The test and experiment indicate that it can work half a year safely and steadily without voltage shortage.
