Overturn prevention device, overturn prevention method and concrete mixing truck

The invention relates to an overturn prevention device, an overturn prevention method and a concrete mixing truck and is characterized in that the overturn prevention device comprises a controller and an inclined angle sensor, wherein the inclined angle sensor is arranged on the frame of an engineering vehicle and electrically connected with the controller; the controller performs overturn prevention treatment according to the inclined angle, collected by the inclined angle sensor, of the engineering vehicle and the angle preset in the controller. According to the overturn prevention device, the inclined angle sensor and the controller are combined; the specific inclined angle of the concrete mixing truck during running can be accurately and timely measured by virtue of the angle measuring function of the inclined angle sensor and directly transmitted to the controller; overturn prevention treatment is performed by the controller, so that overturn accidents are effectively avoided.
