Detailed Description
The technical scheme of the utility model is further explained by combining the attached drawings.
As shown in fig. 1 to 4, the gate device based on the radar detection technology according to the present invention includes a master case 1, a slave case 2, a gate controller 3, a motor 4, a distance measuring radar 5, an AI camera 6, a strip through hole 7, an authentication unit 8, a swing door mechanism 9, and an alarm unit 10.
As shown in fig. 1 to 3, a gate passage is formed between the master casing 1 and the slave casing 2, and constitutes a main body of the gate apparatus. Be provided with floodgate machine controller 3 in the host computer box 1, with range radar 5, the motor 4 of floodgate machine controller 3 through serial communication line connection, range radar 5 installs on the output shaft of motor 4, and motor 4 drives range radar 5 with the rotational speed of 80ms round and rotates to form a plurality of detection angles, range radar 5 sends each angle range finding numerical value to floodgate machine controller 3. The motor 4 is a small-sized stepping motor or a servo motor, and the range radar 5 can be one or a combination of ultrasonic radar, millimeter wave radar and laser radar. One side of the ranging radar 5 corresponding to the gate channel is provided with a strip-shaped through hole 7, and radar ranging waves or ranging light beams are directly emitted outwards through the strip-shaped through hole 7 to measure the distance. The AI camera 6 connected with the gate controller 3 is installed obliquely above the gate channel, identifies the gate channel without dead angles, and outputs the judgment result of the position of the person in the gate channel to the gate controller 3.
