The invention provides an elevator landing door lock state abnormity self-detection alarm device, which comprises each floor calling ladder system and a cable electrically connected with a subsystem, each floor calling ladder system comprises an outbound plate of an elevator and a landing door lock corresponding to a hall, each outbound plate is electrically connected with an auxiliary contact, and the auxiliary contact is a normally closed switch. According to the elevator landing door control system, the normally-closed auxiliary contacts are additionally arranged on the landing door of each floor, and the standby input BY of the outbound board is connected, so that on the premise that no extra hardware is added, only the auxiliary contacts need to be installed on the landing door, and the landing door can be connected with the elevator landing door through the standby input BY. Therefore, the fault landing door can be quickly distinguished and the fault information can be displayed on the nixie tube of the mainboard. When the lifting height of the elevator is high or the landing doors (or safety doors) are many, the hall of any landing door is not completely closed or the door is blocked to close the door due to the action of external wind power, field maintenance personnel can quickly judge through information of the main board, and troubleshooting layer by layer is not needed.

    本发明提供一种电梯层门锁状态异常自检测报警装置,包括各层呼梯子系统以及电性连接子系统的电缆,每层呼梯子系统均包括电梯的外呼板以及与门厅对应的层门锁,每个外呼板均电性连接有辅助触点,且辅助触点为常闭式开关,同时每个与外护板相对应的辅助触点均安装在对应的电梯门厅上,本发明在各层厅门加常闭式的辅助触点,并接到外呼板的备用输入BY,在不增加额外的硬件的前提下,只需要在厅门上安装辅助触点,即可快速判别故障厅门并将故障信息显示在主板的数码管上;在电梯提升高度较高时或者层门(或安全门)多时,任意一层门的门厅没有完全关闭或受外界风力作用导致门受阻关门故障时,现场维修人员可通过主板信息快速判别,无需逐层排查。
