The invention relates to a touch-free key control device of an elevator. The device comprises a central control device and a key input circuit matched with the central control device, wherein a face recognition device, a voice input device and a two-dimensional code scanning device are further arranged, the output of the key input circuit is connected with a corresponding input/output interface ofthe central control device, a signal input switch of the key input circuit is an automatic induction switch or a switching circuit formed by connecting the automatic induction switch and a key switchin parallel, and the central control device controls the elevator to operate according to an input signal after receiving the input signal of any one of the face recognition device, the voice input device, the two-dimensional code scanning device and the automatic induction switch. The device is advantaged in that a user can operate and control the elevator without directly contacting the elevator key, so direct contact between a hand and the key is avoided, and the sanitation and safety hidden danger caused by contacting the key is eliminated.
本发明涉及电梯免触摸按键操纵装置,其包括中央控制装置及与所述中央控制装置配套的按键输入电路,并设有人脸识别装置、语音输入装置、二维码扫描装置,所述按键输入电路的输出接入所述中央控制装置的相应输入输出接口,所述按键输入电路的信号输入开关为自动感应开关或者为自动感应开关与按键开关并联成的开关电路,所述中央控制装置在接收到人脸识别装置、语音输入装置、二维码扫描装置及自动感应开关中任意一种的输入信号后,依据该输入信号控制电梯运行。因此使用者无需直接接触电梯按键就能够对电梯运行操控,避免了手与按键的直接接触,消除了因接触按键带来的卫生安全隐患。
