The method for detecting the anti-intrusion and danger approaching alarm of the mining excavation transportation equipment according to claim 6, wherein the sound alarm driving mode of the embedded control module adopts a long-ringing or gradual-change mode, when the long-ringing mode is selected, the alarm output signal of the embedded control module is a constant-voltage level signal, the sound and light alarm module performs circular playing according to preset alarm voice, when the gradual-change mode is selected, the alarm output signal of the embedded control module is a variable-frequency pulse voltage signal, the closer the distance between the portable signal terminal and the core controller is, the higher the output frequency of the pulse voltage signal is, the faster the frequency of the sound and light alarm module sends the 'tic' sound is, and the driver can judge the distance between the personnel and the equipment or between the equipment and the equipment through the speed of the alarm voice frequency.
