The thermal imaging device is used to obtain a first image of a pedestrian in a first detection area, and obtain the face temperature of the pedestrian according to the first image. The first detection area is the area that the pedestrian passes through before passing through the security inspection door; the metal detection device is used to detect whether the pedestrian carries metal when the pedestrian is in a second detection area. The second detection area is the area under the security inspection door; the alarm device is used to give an alarm when the face temperature is greater than or equal to a preset temperature, and / or it is determined that the pedestrian carries metal. The solution of the embodiment of the present application can improve the efficiency of temperature measurement during security inspection and ensure the safety of security inspection personnel.

[0003] The technical solution proposed by this application can detect metals and detect temperatures. Especially when performing face recognition, it is not easy to detect when the position of the person being inspected moves. At the same time, the set metal detection device is far from the person being detected, and the detection accuracy is relatively low. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an examination room security inspection door device for the Internet of Things, which solves the problems raised in the background technique.

The upper and lower two retracting mechanisms are connected by the same traction rope. A metal detector is fixedly installed on the outer surface of the traction rope. A groove is arranged on the outside of one of the closing plates. A limiting sleeve is fixedly arranged inside the groove. A sliding mechanism that slides up and down is arranged inside the limiting sleeve. The metal detector is also installed on the side of the sliding mechanism close to the door frame. The sliding mechanism extends above the top cover. A transverse protrusion is arranged at the front end of the closing plate provided with the groove. A photographing mechanism is slidably connected up and down inside the transverse protrusion. The transverse protrusion, the door frame and the sliding mechanism are arranged parallel to each other front and back.

[0007] Further, the sliding mechanism includes a sliding rod which is slidably connected inside the limiting sleeve. A lead screw is rotatably connected to the middle of the limiting sleeve, and the lead screw is threadedly connected to the middle of the sliding rod.

[0008] Further, the sliding mechanism includes a counterweight rod which is slidably connected inside the limiting sleeve. The winding mechanism is fixedly installed above the top cover, and the towing rope is fixedly connected to the counterweight rod.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 - 6 , a test room security door device for the Internet of Things, comprising a central axis 1, four annularly distributed door frames 2 are fixedly installed on the outer surface of the central axis 1, a top cover 3 is arranged on the top of the door frame 2, and semi-annular closing plates 4 are fixedly installed on both sides of the top cover 3, and a winding mechanism 5 is fixedly installed inside the upper and lower beams of the door frame 2, and the upper and lower winding mechanisms 5 are connected by the same traction rope 6, and a metal detector 7 is fixedly installed on the outer surface of the traction rope 6, and a groove 8 is arranged on the outer side of one of the closing plates 4, and a limit sleeve 9 is fixedly arranged inside the groove 8, and a sliding mechanism 11 that slides up and down is arranged inside the limit sleeve 9, and the metal detector 7 is also installed on the side of the sliding mechanism 11 close to the door frame 2, and the sliding mechanism 11 extends to the top of the top cover 3, and a transverse protrusion 10 is arranged on the front end of the closing plate 4 with the groove 8, and a shooting mechanism 12 is connected to the inner side of the transverse protrusion 10 for sliding up and down, and the transverse protrusion 10, the door frame 2 and the sliding mechanism 11 are arranged in parallel front and back.

[0024] The sliding mechanism 11 includes a sliding rod 111, which is slidably connected to the inside of the limit sleeve 9. The middle part of the limit sleeve 9 is rotatably connected to a lead shaft 112, and the lead shaft 112 is threadedly connected to the middle part of the sliding rod 111. Through such an arrangement, the height of the sliding rod 111 can be accurately adjusted, making the detection more accurate.

[0025] The sliding mechanism 11 includes a counterweight rod 121. The counterweight rod 121 is slidably connected inside the limit sleeve 9. The winding mechanism 5 is fixedly installed above the top cover 3. The towing rope 6 is fixedly connected to the counterweight rod 121. By towing and releasing the winding mechanism 5, the counterweight rod 121 can move up and down. This method has a relatively low cost.

[0026] The winding mechanism 5 includes a motor 501. A winding wheel 502 is fixedly installed at the output end of the motor 501. The towing rope 6 is wound around the outer surface of the winding wheel 502. A reversing wheel 503 is arranged at the front end of the winding wheel 502. The towing rope 6 is sleeved on the outer surface of the reversing wheel 503. By rotating the motor 501, the winding wheel 502 can be driven to rotate, and then the towing rope 6 after being reversed by the reversing wheel 503 can be released or wound. The sizes of the winding mechanisms 5 at different positions are different.

[0027] A bearing groove 13 is arranged between the closing plate 4, the door frame 2 and the groove 8. An identity recognition mechanism 14 is placed inside the bearing groove 13. The identity recognition mechanism 14 can be set as an ID card recognizer or a fingerprint recognizer according to different examination requirements. Through such a setting, the person to be security-checked can perform identity recognition in a relatively enclosed environment.

[0028] The cross-sectional shape of the metal detector 7 is "L" shaped. The length of the vertical end is greater than the thickness of the beam body of the door frame 2. Through such a setting, it can be ensured that the metal detector 7 can detect the lowest part to avoid concealment in shoes.

[0029] During use, by rotating the central shaft 1, the door frame 2 can be driven to rotate. The person to be security-checked follows the door frame 2 and enters between the two closing plates 4. By moving the sliding mechanism 11 downward, the metal detector 7 can move up and down. The metal detector 7 connected to the door frame 2 can move up and down behind the person to be security-checked under the action of the winding mechanism 5 to achieve detection. Due to space limitations, at this time, the person to be security-checked is facing the photographing mechanism 12, and the front image can be accurately recognized, and metal detection can be performed at a relatively close position.

[0030] At the same time, the photographing mechanism 12 can be at the height of the person to be security-checked. Through Internet of Things transmission, the sliding mechanism 11 can be driven to move quickly when it is above the height of the person to be security-checked, and the moving speed can be slowed down after approaching. At the same time, when the security check fails, the central shaft 1 can be driven to rotate in the reverse direction through Internet of Things transmission.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
