Abstract: The thermographic system to check and prevent fires in a vehicle including at least a plurality of sensors held up by an arch structure and apt to detect the temperature of as many points of the vehicle as the number of sensors and a logic control unit connected to the above mentioned sensors, generating at least an alarm signal if the temperature detected by at least one of the sensors exceeds a pre-established value, which changes (or can change) according to the point of the vehicle checked by the sensor that detected the anomalous temperature. if the thermographic system is placed near a fixed/obligatory way, further sensors fitted into the ground allow to keep under control even the lower part of the vehicle.
