[0037] See Figure 1~3 , The escalator safety detection device of the present invention includes a first eddy current sensor 100 and a second eddy current sensor 200 arranged on both sides of the escalator pedal 300. The first eddy current sensor 100 and the second eddy current sensor 200 are connected to a safety detection processor, wherein the first The eddy current sensor 100 and the second eddy current sensor 200 are shifted by 90 degrees along the forward direction of the pedal, such as figure 1 Shown. The safety detection processor includes an amplifier circuit, an A / D converter, and an MCU chip. The signals of the first eddy current sensor and the second eddy current sensor are transmitted to the MCU chip through the amplifier circuit and the A / D converter, such as image 3 Shown. The device can detect the running information of the escalator through two eddy current sensors. Through the dislocation setting, it can detect the running direction and speed of the steps. At ...
