The invention discloses an elevator safety system and an elevator safety control method.The elevator safety system comprises a grating ruler mechanism, a mounting structure and a tensioning piece, the grating ruler mechanism comprises a grating ruler body, a reading assembly and an inductive switch, the grating ruler body is provided with a first end and a second end in the elevator running direction, and the reading assembly is mounted in an elevator car; the inductive switch is mounted on the reading assembly and has a first position and a second position; the installation structure comprises an installation arm, the installation arm is connected with the first end of a grating ruler body, and the grating ruler body is fixed to an elevator car guide rail through the installation arm. And the tensioning piece is fixedly connected with the second end of the grating ruler body. When the grating ruler mechanism is used, the grating ruler body can be kept vertical through the tensioning piece, and then the reading precision of the grating ruler mechanism is improved. When the tensioning piece falls to the ground after long-term use, the grating ruler body is loosened, or the grating ruler body is fractured to influence the speed monitoring result, the subsequent alarm or stopping action can be triggered through the position change of the inductive switch.

    本发明公开了电梯安全系统及电梯安全控制方法,电梯安全系统包括栅尺机构,安装结构,张紧件,栅尺机构包括栅尺尺身、读取组件、感应开关,栅尺尺身沿电梯运行方向具有第一端和第二端,读取组件安装于电梯轿厢,感应开关安装于读取组件,感应开关具有第一位置和第二位置;安装结构包括安装臂,安装臂与栅尺尺身的第一端连接,栅尺尺身通过安装臂固定于电梯轿厢导轨;张紧件与栅尺尺身的第二端固定连接。在使用时能够通过张紧件保持栅尺尺身的垂直,进而提高栅尺机构的读数精度。当长期使用后张紧件坠地导致栅尺尺身松动,或栅尺尺身断裂影响速度监测结果,能够通过感应开关位置的变换触发后续的警报或制停动作。
