The invention discloses an automatic door triggering method and device and an automatic door. A microwave module transmits a microwave signal to a target space at first power, receives a reflection echo signal, processes the reflection echo signal to obtain a first triggering signal of the automatic door, and calculates the amplitude and frequency of the first triggering signal; the amplitude and the frequency range of an automatic door trigger threshold are preset, the amplitude of the first trigger signal is compared with the amplitude of the preset trigger threshold, the microwave module is switched to enter the second power according to the preset proportion met by the comparison result, the second power is larger than the first power, idle power consumption of the microwave module can be effectively reduced, and the service life of the microwave module is prolonged. And meanwhile, the accuracy and sensitivity of the microwave module during normal working are ensured, and the service life of the microwave module is prolonged.
本发明公开了一种自动门触发方法、装置及自动门，微波模组以第一功率向目标空间发射微波信号，接收反射回波信号，处理反射回波信号获得自动门的第一触发信号，计算得到第一触发信号的幅值和频率，预设自动门触发阈值的幅值和频率范围，将第一触发信号的幅值与预设触发阈值的幅值进行比较，根据比较结果所满足的预设比例，切换微波模组进入第二功率，第二功率大于第一功率，能够有效降低微波模组的闲时功耗，同时保证微波模组正常工作时的准确度和灵敏度，提升微波模组的寿命。
