The invention discloses a safety control device of passenger conveying equipment. The safety control device comprises a logic execution module, a contactor module and a safety relay module. The contactor module comprises a plurality of contactors for controlling the on-off of power supplies of the motor and the working brake; the safety relay module comprises a plurality of safety relays used for controlling on-off of power supplies of the working brake and the additional brake. The logic execution module comprises a main control unit, a signal input unit, a logic driving unit and a plurality of relays; each relay is used for controlling the on-off of a coil power supply of one contactor or one safety relay; each relay is provided with a corresponding logic driving unit; each contactor and each safety relay are provided with corresponding signal input units; and the main control unit sends a control signal to the logic driving unit according to a preset operation mode of the passenger conveying equipment, and judges whether actions of the contactor and the safety relay are abnormal or not according to whether the control signal is matched with the state feedback signal or not.

    本发明公开了一种乘客输送设备的安全控制装置,包括逻辑执行模块、接触器模块和安全继电器模块;接触器模块包括多个用于控制电动机和工作制动器电源通断的接触器;安全继电器模块包括多个用于控制工作制动器和附加制动器电源通断的安全继电器;逻辑执行模块包括主控单元、信号输入单元、逻辑驱动单元和多个继电器;每个继电器用以控制一个接触器或安全继电器线圈电源的通断;每个继电器配置有对应的逻辑驱动单元;每个接触器和安全继电器配置有对应的信号输入单元;主控单元根据乘客输送设备的预设运行模式向逻辑驱动单元发送控制信号,根据控制信号和状态反馈信号是否匹配来判断所述接触器和安全继电器的动作是否异常。
