The invention discloses a tire burst detection device applied to automatic drive. The tire burst detection device comprises a machine body, a ribbed plate, an installation hole and a screw hole, wherein the ribbed plate is arranged on the outer side of the surface of the machine body, a sensor board is arranged on the lateral side of the ribbed plate, and an installation plate is arranged on the lateral side of the machine body. The tire burst detection device has the beneficial effects that a distributed fiber sensor is utilized to obtain stress information in a tire outside the sensor boardin real time and transmit the stress information to a controller; when the stress change information is higher than a preset value, a buzzer can give out alarm sound to remind a user to detect the tire timely, and tire burst is avoided; meanwhile, a rotation speed sensor is arranged to obtain rotation speed information of the tire in real time and display the rotation speed information on a display screen in real time for the user to observe and know; furthermore, a feedback control loop composed of a temperature sensor, a controller and a servo motor is arranged, and the servo motor can be automatically started to work to drive a fan blade to rotate to perform forced cooling on the device when a temperature is too high; use functions of the device is enriched, and a requirement of the automatic drive is adapted.
