【Abstract】 A transformer oil temperature monitoring system based on LPC1768 is designed,including hardware design and software design.The hardware part is mainly composed of a power supply unit,a communication module,and a fan control unit;the software part is divided into a lower computer monitoring terminal software program and an upper computer real-time monitoring interface software.The temperature sensor collects temperature data and uploads it to the monitoring terminal for calculation processing,executes the corresponding decision,and then uploads the data to the background host.The background monitoring software can monitor and view the temperature of the transformer in real time,and the fan can be remotely controlled to achieve the purpose of cooling the transformer.And the surface of the radiator is sprayed with graphene to increase heat dissipation,so that the transformer can have a better cooling effect.更多还原
