The application discloses a kind of high-speed railway train active anti-derailing devices of rail clamping restraint type, including fixed seat, rail pressing wheel frame, clamping arm, rail pressing wheel and rail clamping wheel;Cross-shaped slot is provided on fixed seat, and the ends of the horizontal slot of cross-shaped slot are elastically mounted with rail pressing wheel frame respectively, a pair of clamping arms that can be opened and closed in the longitudinal slot of cross-shaped slot are hinged between two rail pressing wheel frames, rail pressing wheel is installed at the bottom of rail pressing wheel frame, and rail clamping wheel is installed at the end of clamping arm.The fixed seat is fixed on the side beam bottom plate of train bogie, and the device does not affect the normal running of train.When there is a tendency of derailing, the rail pressing wheel presses the top surface of the track, and the two rail clamping wheels simultaneously clamp and hold the two sides of the top of the track, realizing omnidirectional rapid and safe braking, and ensuring the train to stop steadily on the track.When the train resumes normal running, the wheel bogie is reset upwards, the rail pressing wheel is separated from the top surface of the track, the rail pressing wheel frame is restored to the initial state downwards, and the clamping arm is opened to the initial state, without affecting the normal running of train.

This invention discloses a remotely controllable hydraulic self-unloading mining car, relating to the field of self-unloading mining car technology. The self-unloading car includes a conveyor mounted on the lower surface of the rear of its frame. A track is installed on the conveyor, and several first drive motors are mounted on the outer surface of the conveyor's rotating working surface. Each first drive motor has a second drive motor mounted at its front end. A retractable and foldable folding and pushing mechanism is mounted on the front surface of each second drive motor. By setting a conveyor, folding and pushing mechanism, and a winding mechanism below the rear of the self-unloading car frame, this invention can actively push the material at the rear of the car backward during unloading, clearing material accumulation below the discharge port in real time. This fundamentally prevents material from blocking the rear of the car and causing unloading interruptions, enabling continuous unloading without the vehicle moving forward, significantly improving unloading efficiency.

The application discloses a kind of fatigue driving monitoring method, equipment and medium based on cloud intelligent learning, belong to the technical field of automobile monitoring.The method comprises: obtaining the monitoring video data of driver, and sends to cloud;Monitoring video data is handled based on image preprocessing algorithm, to extract multiple facial features of driver;Multiple facial features are handled based on fatigue identification model, to determine fatigue degree;Fatigue degree is sent to cloud based on early warning;Cloud database is handled based on cloud computing module, and iterative operation training identification model is operated, to obtain the deviation of training identification model, the training identification model of minimum output deviation;The weight factor of minimum training identification model of deviation is obtained by processing minimum training identification model of deviation based on reverse operation algorithm, and fatigue identification model is updated.The application improves the accuracy, popularity and stability of monitoring fatigue driving by the above method, while not affecting the normal driving of driver.

This invention discloses an on-board activated permanent magnet eddy current anti-collision buffer system, road anti-collision supporting facilities, and working method, belonging to the technical field of automotive safety protection technology and road traffic safety facilities. The on-board anti-collision host is installed at the anti-collision beam position at the front of the vehicle body. The on-board anti-collision host includes a shieldable permanent magnet array assembly, a drive mechanism, and a trigger control unit. The shieldable permanent magnet array assembly includes a high permeability shielding shell and a permanent magnet array. The high permeability shielding shell is a closed cavity structure with one open end. The permanent magnet array is slidably assembled within the receiving cavity of the high permeability shielding shell. The power output end of the drive mechanism is fixedly connected to the permanent magnet array. The trigger control unit is electrically connected to the drive mechanism and controls the drive mechanism to perform an activation action according to preset trigger conditions. This invention achieves non-contact, smooth deceleration and buffering in scenarios where a vehicle collides with a fixed obstacle.

The utility model relates to self tipping car technical field, and disclose a self tipping car convenient for unloading, including the car body, the bottom of car body is provided with stabilizing mechanism, the stabilizing mechanism includes fixed frame and support plate, the fixed frame is installed at the bottom of car body, the number of support plate is two, two the support plate symmetrical setting is in the bottom of fixed frame. The utility model through the symmetrical setting's double support plate, can according to the flexible adjustment unilateral support plate's support state according to the unloading direction, before unloading, the corresponding side support plate is put down to the ground, and the other side support plate is kept in the retracted state simultaneously, to guide the car body gravity center to the non unloading side deviation, so that two support plates play the effect of support and counterweight, effectively reduce the rollover risk caused by material heavy load, rugged ground, thereby guarantee equipment, material and operator safety.
