[0060] An intelligent positioning method for high-risk social personnel, comprising:

[0061] Step 1: Load the existing map data into the map module of the management center and mark the locations of each monitoring device and radio receiving device;

[0071] Embodiment 2:

[0072] like Figure 4-8 As shown, the base 13 is a movable base, and the movable base includes wheels 133, a driving device (not marked), a fixed base plate 131, a support seat 135, and a vacuum adsorption device. The wheels are fixed to the support seat through bearings, and slide rails 134 are provided on both sides of the support seat. A slide groove is provided in the slide rail. The vacuum adsorption device includes a base 137, a vacuum pump (not marked), an exhaust pipe 136 and an adsorption head 132. Both sides of the base are located in the slide groove and are slidably connected to the slide groove. The adsorption head is fixed on the base, one end of the exhaust pipe is connected to the vacuum pump, and the other end of the exhaust pipe can be connected to the exhaust port of the adsorption head; the driving device and the vacuum pump are both connected to the power module.

[0073] The adsorption head includes a base tube 1324 and an arc-shaped portion 1322, the base tube 1324 is located in the base body 137, an air inlet hole 1327 is provided at the connection portion between the base tube 1324 and the arc-shaped portion, a magnetic part 1325 and an air suction port 1326 are provided at one end of the base tube away from the arc-shaped portion, a one-way valve 1323 is provided in the base tube near the air inlet hole, and the one-way valve is located between the air inlet hole and the air suction port.

[0074] A pull strip 1321 is provided on the outer surface of the outer edge of the arc-shaped portion, and the pull strip causes the outer edge of the arc-shaped portion to bend upward.

[0075] The vacuum adsorption device and the driving device are both electrically connected to the processor, and the vacuum adsorption device and the driving device are controlled by the processor.

[0076] The power module provides power for the driving device and the vacuum pump. The driving device is used to control the movement of the wheel, including an electronic controller, a motor, a transmission device, etc., which are prior arts and will not be described in detail here.

[0077] Before using the monitoring device, the camera is installed on a fixed bottom plate. First, manually pull the base to slide, so that the base tube of an adsorption head is aligned with the exhaust pipe next to the front wheel through magnetic attraction, and then turn on the power device, the vacuum adsorption device starts to evacuate, and then the entire front-end intelligent sensing device is placed on a smooth attachment surface, and the base is squeezed appropriately to make the wheel contact the attachment surface (when the wheel contacts the attachment surface, the arc-shaped part of the adsorption head located below the wheel is compressed and close to the attachment surface, and the height of the arc-shaped part of the adsorption head that does not contact the attachment surface is higher than the outer edge of the wheel). Due to the pressure, the air inlet is closed, and the air inside the arc-shaped part is discharged through the one-way valve. At the same time, the vacuum pump will also extract the air in the arc-shaped part. At this time, the air in the arc-shaped part of the adsorption head is sucked out, so that the arc-shaped part of the adsorption head is adsorbed on the attachment surface, thereby adsorbing the entire device on the adsorption surface. Then the driving device drives the wheel to rotate. The wheel rotates and the base moves. During the rotation of the wheel, the arc-shaped portion of the adsorption head is adsorbed on the attachment surface, causing the base to slide in the slide groove. The sliding of the base drives the movement of the adsorption head. When the adsorption head moves to the bottom of the rear wheel and rotates again, the pressure gradually decreases, causing the air inlet to open, allowing air to enter the arc-shaped portion. After air enters the arc-shaped portion, the vacuum disappears, causing the arc-shaped portion of the adsorption head to separate from the attachment surface, thereby not hindering the movement of the base.

[0078] The monitoring device using this base can move freely on the smooth attachment surface.

[0079] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
