摘 要

现代电力系统向着高电压、大容量、更复杂的机组不断进步，对电力系统。供电的稳定性、安全性的要求也越来越高。，。而电气设备运行时不可避免。的温度升高会阻碍。电气设备的。运行，降低。电气设备的。运行效率，甚至设备发热将引起设备故障、停电，甚至爆炸，危及运行人员的生命安全。由于传感器和无线通讯等的相关领域不断发展，各种测量方法被用在了电气设备温度监控方面。

本课题针对电气设备测温的特殊性，设计了一套温度检测系统，设计和实现了系统的硬件和软件。该系统以Arduino单片机为主控机，通过无线蓝牙接收多个从机测量值，然后由Arduino主控机再将所有数据传输回移动监测终端实移动性时显示，系统具有可扩展性。

通过对其单点温度变化测量、多点温度测量、蓝牙通讯距离测试以及移动检测平台下测温功能的测试，所设计的电气设备测温系统能力正常。所测温度变化区间为-55℃--125℃，所设检测蓝牙通讯距离为12m，测试结果表明，蓝牙模块A在11m时有效，12m时失效；蓝牙模块B在10m时有效，11米时失效，所以本设备主从机的有效检测距离为10m。

Design of temperature measuring system for electrical equipment based on Arduino

ABSTRACT

Modern power systems are progressing toward high voltage, large capacity, and more complex units. The stability and safety requirements of power supply are higher and higher. ,. The electrical equipment is unavoidable. The temperature rise will hinder. Electrical equipment. Run down. Electrical equipment. Operating efficiency, even heating equipment, will cause equipment failure, power failure, or even explosion, endangering the safety of the operators. Because of the continuous development of sensors and wireless communications, a variety of measurement methods have been applied to the temperature monitoring of electrical equipment. In this paper, a temperature detection system is designed for the particularity of temperature measurement of electrical equipment. The hardware and software of the system are designed and implemented. The system uses Arduino microcontroller as the main control computer through wireless Bluetooth to receive multiple measurements from the machine, and then by the Arduino controller and then all data transmitted back to the mobile monitoring terminal display system has the real mobility, scalability.

Through the single point temperature change measurement, multi-point temperature measurement, Bluetooth communication distance test and mobile testing platform temperature measurement function, the design of electrical equipment temperature measurement system ability is normal. The measured temperature range of -55 DEG --125 DEG, the detection of Bluetooth communication distance is 12M, the test results show that the A Bluetooth module in 11m, 12m failure; Bluetooth module B available in 10m, 11 metres failure, so the equipment of the master-slave detection distance is 10m.
