In describing embodiments of the present invention, the terms "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and other terms are used in an orientation or positional relationship shown in the associated drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Fig. 1 is a block diagram schematically showing a control device according to an embodiment of the present invention. The utility model discloses a controlling means adopts wireless remote control's control mode equally, consequently this device includes remote controller 1 and the total controller 3 that is used for receiving the signal that remote controller 1 sent. In this embodiment, the main controller 3 is a single chip microcomputer. And in order to avoid other equipment to pass through wireless signal control semitrailer, the utility model discloses a remote controller 1 is through high frequency wireless encryption carrier to total controller 3 transmission signal, is decoded encryption signal by total controller 3 again. Therefore, the singlechip (namely the master controller 3) is integrated with a decoding circuit, so that the singlechip has a password identification function. The utility model discloses central control box 2 has been set up to can pack into this control box with total controller 3, be convenient for install and be favorable to protecting corresponding electronic components.

As shown in fig. 1, the remote controller 1 is further provided with four operation buttons for controlling the semitrailer to complete unloading and recovery and the opening and closing functions of the rear door. And because central control box 2 and remote controller 1 do not share the power, consequently in order to avoid remote controller 1 electric energy to exhaust or the damage appears in the use, the utility model discloses also be equipped with corresponding operating button on central control box 2.
