Electric shifting machine

The utility model relates to a wireless remote control device for a hospital bed, which comprises a wireless remote controller and a receiving controller part, wherein, the wireless remote controller is formed by orderly connecting a CPU circuit, a Keelog coding circuit and a transmitting circuit; the receiving controlling part is formed by orderly connecting a receiving circuit, a decoding circuit, a mixing driving circuit and a motor, wherein, the mixing driving circuit is controlled by a wired hand controlling circuit. The device is formed by adopting the combination of wireless remote control and auxiliary wired control. Remote operation or operation through wired controlled equipment can be realized, which is suitable for the requirements of patients with various diseases. The utility model has the advantages of reasonable design and simple circuit. A single chip computer and the Keelog coding technique are adopted, ensuring the coding uniqueness. Fault remote control between different hospital beds can not happen. Through the designs of the circuit and the program, goals of intelligent protection and safe running can be achieved.
