The invention discloses an electric bicycle identification blocking early warning system for an elevator. The electric bicycle identification blocking early warning system comprises a control box connected with a power supply, a photoelectric switch connected with the power supply, a plurality of pressure sensors, a magnetic field sensor and a microwave transmitter, and the photoelectric switch, the pressure sensors, the magnetic field sensor and the microwave transmitter are electrically connected with the control box. From the structure, by utilizing the characteristic that an infrared receiver is prone to being interfered by radio frequency radiation signals such as microwaves and then loses efficacy, when an electric bicycle goes in and out of the elevator, the electric bicycle identification blocking early warning system for the elevator directly interferes the infrared receiver arranged on the elevator through the microwave transmitter to make an elevator door be kept in an opened state after simultaneously receiving a pressure signal of the electric bicycle and a magnetic field signal of a driving motor of the electric bicycle.

    本发明公开了一种升降电梯的电动自行车识别阻挡预警系统,包括与电源连接的控制箱、与电源连接的光电开关、多个压力传感器、磁场传感器和微波发射器,所述光电开关、压力传感器、磁场传感器和微波发射器分别与控制箱电连接。从上述结构可知,本发明的升降电梯的电动自行车识别阻挡预警系统,利用红外线接收器易受到微波等射频辐射信号干扰而失效的特性,当有电动自行车进出电梯的时候,同时接收到电动自行车的压力信号和电动自行车驱动电机的磁场信号后,直接通过微波发射器干扰升降电梯门自带的红外线接收器而使电梯门保持打开状态。
