Transformer Temperature Automatic Monitoring and Control System Based on AT89C51
To reduce the probability of transformer damage and improve work efficiency,this paper proposes a trans-former temperature automatic monitoring and control system based on AT89C51.The system collects temperature in real-time through the DHT11 sensor,and AD0804 converts the temperature into digital data,which is transmitted to the AT89C51 microcontroller for monitoring.When the temperature exceeds the threshold,the system will alarm and activate the temperature controller.The controller combines the fuzzy PID method to calculate the control quantity and sends instructions to AT89C51 for temperature control.The experiment shows that the system monitors tempera-ture accurately,has high sensitivity,and can quickly cool down.This system effectively ensures the stable operation of transformers and improves operational efficiency.
