Problems solved by technology

[0011] (1) Video analysis technology. This technology uses the image analysis camera to drive the tracking of the shooting camera by the change of the area image before and after. This technology will cause inaccurate tracking when the lights and curtains on the scene change. It is the case of no tracking; it is impossible to achieve the effect of automatic tracking and shooting of multiple people on the podium and the effect of teachers walking to the front of the student area, and cannot support large classrooms, etc.
[0012] (2) Infrared detection technology, this technology needs to install red infrared emitting strips and infrared receiving devices around the classroom, the construction is particularly troublesome and the later maintenance period is long; and it is impossible to distinguish between students standing or raising their hands
[0013] (3) Ultrasonic technology, this technology requires the installation of many ultrasonic inference modules on the lower edge of the blackboard, and cannot realize intelligent tracking in the student area. The student area needs to increase voice tracking or infrared button tracking
[0014] (4) The problem of the cable protection device, the cable protection shell needs to be made on site according to the actual situation, which is time-consuming and laborious, and there is no general product

Embodiment 1

[0079] see Figure 4 As shown, an intelligent tracking device based on radar detection includes: behavior point sensing device, positioning controller, behavior detection analyzer, behavior detection and analysis control panel, behavior control publisher, data storage, power interface, network interface, Connect cables, cable protectors.

[0080] The behavior point sensing device is composed of a laser emitting device and a laser receiving device. The laser emitting device and the laser receiving device are arranged correspondingly. The laser emitting device is used for continuously emitting laser lines, and the emitting frequency is 25-50 times per second. The behavior point sensing device adopts the following structure:

[0081] The behavior point sensing device is placed at the rear or side of the classroom. The laser emitting device emits pulse waves continuously in actual use. The laser pulse waves hit the high-speed rotating mirror and emit pulse waves in all directions...

Embodiment 2

[0107] Compared with Embodiment 1, the behavior point sensing device adopted in Embodiment 2 adopts the following structure:

[0108]The behavior point sensing device is placed at the rear or side of the classroom, and the viewing angle of the installation position is convenient for observing the students in the classroom and the teacher on the podium; one or more laser emitting devices correspond to a laser receiving device, and a large number of laser emitting devices and The laser receiving devices are densely distributed on the outer surface of a sphere. These laser emitting devices emit laser lines from the center of the sphere to the surroundings. Each laser line is emitted by the laser emitting device and received by the laser receiving device; the spherical shape composed of the laser emitting device and the laser receiving device The structure has an opening at the bottom, which is circular, for mounting the support frame and cables.

Embodiment 3

[0110] Different from Embodiments 1 and 2, the behavior point sensing device adopted in Embodiment 3 adopts the following structure:

[0111] Laser emitting devices and laser receiving devices are placed on the walls around the classroom, one laser emitting device corresponds to one laser receiving device, a large number of laser emitting devices and laser receiving devices are densely distributed on each wall, and each laser line is composed of The laser emitting device emits and is received by the laser receiving device. The laser line emitted by the laser emitting device is perpendicular to the wall on which the laser emitting device is installed; the densely distributed behavior point sensing devices form a horizontal and vertical scanning grid, forming a Scanning the plane grid, when an object blocks any scanning line in the grid, the two-dimensional coordinates can be determined according to the blocked horizontal and vertical laser lines. A cable port is installed at th...
