Train track inspection

Control: ESP32 (advantages: built-in wifi module, low power consumption, stable, meeting the needs of this design). Temperature collection: DS18B20 temperature sensor (strong anti-interference ability, reducing measurement temperature error). Display: OLED screen (low power consumption, light quality of finished product). Alarm module: Study how to send an alarm signal after the temperature exceeds the limit. Temperature control module: Mainly studies how to regulate rail temperature
(1) The display screen can display parameters such as the actual measured temperature of the rail, temperature curve, time and date. (2) Alarm when the rail temperature exceeds the limit range (3) Cool down the rails that are too hot. (4) Send rail temperature information to the host computer via wifi.
The train real-time monitoring system consists of three parts: temperature detection and control, train number and wheel identification, and data terminal processing. I am responsible for the temperature detection and control of train tracks, and use ESP32 as the main control core of the system to implement the algorithm. The OLED display is used to display parameters such as the measured temperature, time and date of the railway track. DS18B20 is used for temperature acquisition; the keyboard circuit is used to set relevant parameters, such as upper and lower temperature limits and time. An alarm circuit is used for temperature over-limit alarm, a semiconductor refrigeration chip is used to control the rail temperature, and the rail temperature information is sent to the host computer through WiFi.
