The new coronary pneumonia has high infectivity, and for the prevention and control of the new coronary pneumonia, the development and the propagation of the new coronary pneumonia can be effectively controlled only by detecting suspected patients and effectively controlling the infection paths of the patients. One of the main symptoms of the early stage of new coronary pneumonia is fever, so that the detection of the body temperature of a population to distinguish suspected patients is a main method adopted at present.
The body temperature gun is the most commonly used detection equipment at present, and it has advantages such as small in size, convenient to use, nevertheless to the great occasion of flow of people, its use still has great limitation. 1. The body temperature gun needs to be manually aligned to a specific part of a human body for detection, so a large amount of workers are needed for operation, and meanwhile, although each detection only consumes 5-10 seconds, when the flow of people is large, the total time consumed is large, phenomena such as queuing and congestion often occur, and normal traffic is influenced. 2. Theoretically, it is entirely feasible to apply infrared thermal imaging to detection of heat generation, to capture a thermal image by an infrared imaging camera added to a choke, and to detect suspected cases of heat generation by analyzing the image. However, in experiments, it is found that when people flow greatly, if people watch and analyze the thermal image manually and separate suspected patients from the crowd, the difficulty is high, and many times, because people are too dense, the possibility of misunderstanding exists by only depending on manual separation, and the accuracy and efficiency of heating detection are further affected. 3. In addition, common traffic choke equipment in the market is not suitable for installing infrared imaging equipment, and the products are large in size and not convenient to move, so that popularization and popularization of infrared imaging group temperature measuring devices are limited.

The invention comprises a gate-shaped passing choke, a thermal imaging heating detection device arranged on the passing choke, and intercepting devices arranged at two sides of the passing choke.
The passing choke is used for people to flow through, the thermal imaging heating detection device shoots infrared images, the positions of people who are heated and suspected to be heated in the crowd are obtained through analysis of the infrared images, and finally the positions of the people are marked. The intercepting equipment mainly plays a role in intercepting the people flow and guides the people flow to the passing choke. As shown in fig. 1, the transit choke comprises a U-shaped transit passage for the passage of people and a roof 1 arranged above the transit passage.

The master controller is used for controlling the overall operation of equipment, generally adopts the industrial computer, track marking mechanism 3 and be arranged in marking out the risk personnel among the crowd, track marking mechanism 3 can adopt and can carry out multi-angle pivoted radium-shine laser lamp, shot-light etc. at three-dimensional within range. Usually, the tracking and marking mechanism 3 is composed of a tripod head and a spot lamp installed on the tripod head, and the tripod head is used for controlling the orientation of the spot lamp. In order to carry out thinner marking to distinguish high-risk personnel from suspected risk personnel, the spotlight can adopt a red-yellow double-color spotlight, the red spotlight is used for marking the high-risk personnel, and the yellow spotlight is used for marking the suspected risk personnel. The cloud platform and the red-yellow double-color spotlight are respectively electrically connected with the master controller and are controlled by the master controller.
The infrared imaging camera 2 of the invention can be directly installed on the central top of the top cover 1, but because the infrared image taken by the top of the human head is not sensitive, the better way can be that, as shown in fig. 3, two infrared imaging cameras 2 are arranged on the lower surface of the top cover 1, and the infrared imaging cameras 2 are respectively positioned on two sides of the lower surface of the top cover 1 and face obliquely to the passage passageway. The infrared imaging cameras 2 arranged obliquely can better capture the thermal images of the forehead and the face of a crowd, so that the detection accuracy is improved, and certainly, in the operation process, people flow through a passing choke without wearing a hat and blocking the face and the forehead as far as possible. Considering that a plurality of dangerous persons may exist in a group passing a choke at one time, the present invention may be further preferably configured such that the number of the tracking and marking mechanisms 3 is not less than 4, and the tracking and marking mechanisms may be arranged in a single row or in multiple rows. Secondly, in order to further improve the effect of prompt mark, the side of top cap 1 can also be provided with alarm lamp 4, alarm lamp 4 and total controller electric connection. When the infrared imaging camera 2 shoots the images of the risk personnel, the master controller controls the alarm lamp 4 to be turned on so as to play a role in prompting.
Specifically, the usage method of the thermal imaging heating detection device of the invention is as follows:
A. the infrared imaging camera 2 is used for acquiring an overhead view image in the passage and sending the overhead view image to the master controller for analysis and processing.
B. And the master controller analyzes a high-risk area reaching a high-temperature threshold value and a suspected risk area reaching a suspected threshold value in the overlooking image, and calculates the entity position information of the corresponding passer in the passing aisle according to the image position information of the high-risk area and the suspected risk area in the overlooking image.
C. And the master controller generates a driving signal according to the entity position information and drives the holder to follow the position action of the corresponding passerby, so that the red-yellow spotlight keeps following the corresponding passerby.
D. Under the control of the master controller, the red-yellow double-color spotlight emits red light or yellow light to irradiate the corresponding passerby, the passerby corresponding to the high risk area emits red light, and the passerby in the suspected risk area emits yellow light.
E. The staff screens out the dangerous passers-by from the crowd according to the light color on the passer-by.
The method and the system can mark high-risk and suspected-risk passers from the crowd, save more manpower compared with the traditional mode of confirming the risk personnel from the crowd by manpower, and simultaneously prevent misunderstanding. The mass rapid detection of mass flow crowds can be realized, the influence on normal traffic is extremely small, the phenomenon of congestion queuing can be prevented, and the method is particularly suitable for being used in large-traffic places such as stations, airports and office buildings. Through total controller, control infrared imaging camera and track marking mechanism linkage work, realize the tracking mark to the risk crowd, even under the condition of crowded relatively, also can guarantee the accuracy of mark, the relevance ratio is high.
In addition to the group inspection and marking positioning functions, the present invention also has the following differences, as shown in fig. 1 and 2, the passage passageway is composed of a bottom box 5 and side plates 6 disposed at both sides of the bottom box 5, and the bottom box 5 and the side plates 6 may be an integral structure or may be detachably assembled. A plurality of conveyor belts 7 are arranged in the bottom box 5 side by side, the conveyor belts 7 extend along the length direction of the passing passage, and the conveying surfaces of the conveyor belts 7 form a multi-conveying area in the passing passage, as shown in fig. 1, three conveyor belts 7 are arranged to form three conveying areas. For three rows of people to flow through, it is of course also possible for people to pass by walking without the design of the conveyor belt 7. In order to reduce steps and facilitate people and disabled people to pass through, the front end and the rear end of the passage passageway are respectively provided with a slope plate 8 which is transited from the top surface of the bottom box 5 to the ground. In order to enable people to enter the passing passageways more orderly, a plurality of partition plates 15 are arranged on the slope plate 8, the slope plate 8 is divided into a plurality of passageways by the partition plates 15, and the passageways are in one-to-one correspondence with the conveying areas. Of course, the slope plate 8 can be in a detachable form, and can be detached by workers according to the situation on site.
When the invention is used, people flow is detected in the process of passing through the passage, the top cover 1, the bottom box 5, the side plates 6, the slope plates 8 and the like can adopt fixed structures, but in order to reduce the volume and improve the reasonability of the layout so as to be convenient for transportation and storage, the invention can better practice that the top cover 1 adopts a lifting type top cover 1.

During operation, the lifting motor drives the driving gear 12 to rotate, the driving gear 12 drives the plurality of synchronizing gears 11 to rotate, and the synchronizing gears 11 drive the screw rods 9 to rotate. The screw 9 changes its length of penetration into the threaded sleeve 10 during rotation, so as to change the height of the cap 1. Besides, the slope board 9 of the invention can also adopt a storable form, the slope board 8 is hinged with the edges at the two ends of the bottom case 5, and the slope board 8 is locked with the side boards 6 through the hasps 14. After the use, the invention can lower the top cover 1 and retract the slope plate 9 to form a box-type structure, and the transportation and the carrying can be more convenient because the volume is smaller. The bottom of the bottom box 5 is provided with a caster set, and the caster 16 of the caster set is a caster with a brake. The castors 16 are normally provided in two sets of 4, although more may be provided when the dimensions of the transit aisle are larger.
According to the thermal imaging heating detection device, the passers-by are conveyed through the conveyor belt, the disorder caused by free movement of people is avoided, and the detection effect and the accuracy of the thermal imaging heating detection device are better. The system is reasonable in overall arrangement and compact in structure, can be contracted to a small box-type structure, is convenient to move, and is convenient to build and use in different occasions. Through synchronous lifting of the multiple groups of telescopic mechanisms, the top cover 1 can be lifted and lowered more stably above the passing passageway.

Considering that the length of the storage box 17 is long, if it is inconvenient to extend and take the support rail 20 from the outlet 18, the side surface of the support rail 20 of the invention is further provided with a handle 30, the side surface of the storage box 17 is provided with a through groove 31 matched with the handle 30, and the support rail 20 can be taken quickly through the handle 30. For the part of the support rail 20, because the length thereof is longer, the bottom surface of the storage box 17 of the present invention is provided with a bottom opening 33 extending along the length direction of the storage box 17, and the lower end of the support rail 20 passes through the bottom opening 33 and extends out of the storage box 17.
In addition, cut off interception subassembly still includes many elastic bands 24, the one end rolling of elastic band 24 is on accomodating rotary drum 19, and the other end passes the hole of stepping down 25 on the support railing 20 body of rod and the body of rod rigid coupling of last support railing 20. That is, in his fig. 7, the elastic band 24 is passed through the offset hole 25 of the support rail 20, except that it is fixedly connected to the rightmost one of the support rails 20.
In use, the last support rail 20 is removed and the elastic band 24 is pulled out and stretched. In order to ensure the smoothness when the elastic band 24 is pulled, as shown in fig. 1, a guide shaft 35 is further provided on the storage box 17 on the side of the ejection port 18, and the elastic band 24 can be pulled out by passing around the guide roller 35. After the elastic belt 24 is pulled out, the supporting railings 20 with proper quantity can be selected according to the length of the elastic belt 24, and the middle section of the elastic belt 24 is supported through the supporting railings 20, so that the elastic belt 24 is prevented from sagging, and the stability of the elastic belt is ensured.
Since the yielding hole 25 only allows the elastic band 24 to pass through, the stress on the elastic band 24 in the length direction is not shared by other supporting railings 20 except the supporting railing 20 at the end, so that when the return torsion spring is used as the winding driving force, the elastic band 24 may rebound due to insufficient support. Therefore, as shown in fig. 9, it is further preferable that three rotating rollers 27 are disposed in the receding hole 25, the elastic band 24 goes around the three rotating rollers 27 in a zigzag shape, a threaded hole is disposed in a rod body of one rotating roller 27 located in the middle of the three rotating rollers 27, and a locking bolt 29 is disposed in the threaded hole. The inner end of the locking bolt 29 abuts against the rotating roller 27 to lock the rotating roller 27. When the elastic band 24 is pulled, the locking bolt 29 can be loosened, and the elastic band 24 can freely pass through the abdicating hole 25. When the elastic band 24 is in the right position, the locking bolt 29 can be tightened again, and the force of the elastic band 24 in the length direction is substantially applied to the support rail 20 because the rotating roller 27 in the middle cannot rotate.
The isolation interception component can be conveniently and quickly stored in the storage box and also can be conveniently and quickly taken out of the storage box for arrangement, so that the arrangement of the isolation interception component is more flexible overall, and compared with various conventional assembled devices, the isolation interception component has more application scenes and faster arrangement speed. The supporting railings with different quantities in the intercepting component can be reasonably used and isolated according to the required intercepting length, and the intercepting component is applicable to both large-section intercepting and small-section intercepting, and has extremely strong universality. Can mark out high risk and suspected risk passerby from the crowd, compare with the traditional mode of confirming risk personnel from the crowd through the manual work, more use manpower sparingly, prevent the misunderstanding simultaneously. The mass rapid detection of mass flow crowds can be realized, the influence on normal traffic is extremely small, the phenomenon of congestion queuing can be prevented, and the method is particularly suitable for being used in large-traffic places such as stations, airports and office buildings.
