The invention relates to the elevator technology, in particular to a device for inputting a call command and an elevator control system comprising the device. The device for inputting the elevator calling command according to one embodiment of the invention comprises at least one button unit, wherein each button unit comprises a switching element and a variable resistance circuit coupled with the switching element. The variable resistance circuit comprises a button switch and a display element which are coupled in parallel, and the resistance of the variable resistance circuit changes along with the state of the button switch. The device further comprises a control unit which is configured to determine the state of the corresponding button switch based on the resistance of the variable resistance circuit in each button unit and apply pulse width modulation signals with different duty ratios to the control ends of the corresponding switch elements based on the determined states.

    本申请涉及电梯技术,特别涉及用于输入呼梯命令的装置和包含该装置的电梯控制系统。按照本申请一个实施例的用于输入呼梯命令的装置包括至少一个按钮单元,每个按钮单元包括开关元件和与开关元件耦合的变阻电路。上述变阻电路包含以并联方式耦合的按钮开关和显示元件,该变阻电路的电阻随按钮开关的状态而变化。上述装置还包括控制单元,其配置为基于各个按钮单元内的变阻电路的电阻确定相应的按钮开关的状态,并且基于所确定的状态在相应的开关元件的控制端上施加具有不同占空比的脉宽调制信号。
