The invention discloses an intelligent moving type flip-plate car arrester and a car arresting method thereof. The intelligent moving type flip-plate car arrester comprises a front axle, a box, a rearaxle, a flip plate arranged on the upper portion of the box and a control device arranged in the box. The front axle and the rear axle are connected with the two ends of the box correspondingly, oneend of the flip plate is rotatably connected with the box, and the control device comprises an air spring, a U-shaped guide rail, an inverted-T-shaped sliding block matched with the guide rail, an electric push rod, a forward and reverse rotating motor, a control panel arranged on the flip plate and capable of receiving a remote control signal, a limiting sensor arranged on the control panel, a flip plate lock arranged on the flip plate and an unlocking motor, and the unlocking motor is connected with the control panel; and one end of the air spring is fixedly connected with the flip plate, and the other end of the air spring and the electric push rod are connected to the two sides of the sliding block correspondingly through shafts. According to the intelligent moving type flip-plate cararrester, deployment is convenient, construction is not needed, the road surface is damaged, the problem that an existing car arrester is difficult to be rapidly deployed is solved, the unlocking motor can be remotely controlled to rapidly bounce or close to lock the flip plate, intelligent control is achieved, and the car arresting effect is good.
