Temperature and Humidity Monitoring System of Outdoor Terminal Box in Substation Based on Wireless Communication Technology

For the purpose of accurately and real-time monitoring the temperature and humidity status of the outdoor terminal box of the substation, a temperature and humidity monitoring system for the outdoor terminal box of the substation based on wireless communication technology is designed. The SHT11 temperature and humidity sensor collects the temperature and humidity information of the terminal box, and transmits the information through the wireless communication network. LSTM model is used to identify temperature and humidity anomalies. If there is an abnormal state, it drives the buzzer to alarm. The experimental analysis shows that the temperature and humidity acquisition deviation values of the designed system for the outdoor terminal box of the substation are 0.l°C and 0.1%, respectively. When the temperature and humidity status is abnormal, the alarm time of the buzzer is highly consistent with the actual time, which can accurately and real-time monitor the temperature and humidity status of the terminal box. The wireless communication network used by the system has good anti-interference performance, and the signal strength and data packet receiving ability are significant.
