Description

Technical Field

[0001] The present invention relates to the field of temperature measurement equipment for epidemic prevention, and in particular to a body temperature measurement and prevention and control device. Background Art

[0002] During the peak season for infectious diseases, all venues and facilities need staff to be equipped with temperature measurement equipment to conduct temperature measurement and control on people entering and leaving. Past experience has shown that when public health incidents occur during the peak season for infectious diseases, the workload of staff will surge. For venues and facilities with large flow of people, coupled with the untimely adjustment and supplementation of staff, it will lead to greater work pressure and a greater probability of work burnout and mistakes, resulting in missed inspections due to the influx of people in the chaos.

[0003] To address this phenomenon, some existing technologies provide temperature measurement access control technologies with varying degrees of automation that can perform prevention and control without human supervision. After using this type of equipment, personnel can be dispatched to more important prevention and control entrances and exits. This type of equipment usually includes temperature measurement equipment, gate access control equipment and control processors. Personnel are measured by the temperature measurement equipment, and the control processor determines whether the person's body temperature is abnormal. The gate access control equipment is then controlled to release people with normal body temperatures or block people with abnormal body temperatures.

[0004] However, the above-mentioned technologies are often not well adapted to the entrances and exits of various places / facilities of different specifications, and it is impossible to find temperature measuring gate access control equipment that is well adapted to the sizes of the gates / entrances and exits of the place facilities, reflecting poor adaptability. Some equipment cannot be adapted to be installed on the entrance and exit gates, and cannot provide locking and control functions for the gates themselves. Or, when the access control gate equipment is forcibly arranged outside the entrance and exit gates, since the gates themselves are not directly endowed with temperature measurement and control functions, there is space for people to bypass the gate equipment and enter the gate, which cannot produce a good access control effect, and the control effect is poor, resulting in missed detection problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and to provide a body temperature measurement and control device that can be adapted to various existing door bodies.

[0006] A body temperature measurement and control device provided by the present invention includes: two installation and winding components and a temperature measuring component connected to the two installation and winding components at the same time, wherein the two installation and winding components are correspondingly installed on two matching door bodies, or, correspondingly installed on the matching door bodies and door frames, the temperature measuring component includes a temperature measuring head and a base, the temperature measuring head is connected to the base, the temperature measuring head is used to detect human body temperature, the installation and winding component includes: a mounting member, a winding roller, a blocking belt and a locking mechanism, the mounting member is detachably connected to the door body or the door frame, the winding roller is rotatably connected to the mounting member, the blocking belt is connected between the base and the winding roller, the locking mechanism is connected between the mounting member and the winding roller, and can lock or unlock the winding roller. When the human body temperature detected by the temperature measuring head is higher than the first threshold value, the locking mechanism locks the winding roller so that the extension length of the blocking belt remains unchanged, so that the distance between the two door bodies or between the door body and the door frame remains unchanged, and the door cannot be opened.

[0007] The mounting parts are installed on various door bodies in a detachable connection manner, and the structure used to control the opening and closing of the door body is a blocking belt, which can be deformed in all directions. Unlike various existing mechanical locks, it can adapt to the different opening and closing methods of sliding and swing doors, flip doors and other types of door bodies, and even open entrances and exits, and block the open entrances and exits. In essence, it is an additional accessory detachably connected to the door body, rather than an independent gate system, and has good adaptability. During the period of high incidence of infectious diseases, various places can purchase and install this device to implement temperature detection and control with an automated degree, without the need to set up a complete access control gate with temperature detection.

[0008] Furthermore, considering that although the barrier belt is set near the height of the human head to ensure that the temperature measuring head can measure the temperature of the human forehead, even if the body temperature of the person is normal, the locking mechanism unlocks the winding roller so that the door body can be pushed, but the person still needs to lower his head and bypass the barrier belt to pass. In order to facilitate the movement of people with normal body temperature, the installation part includes: a mounting part and a moving component that drives the mounting part to move, the mounting part slides in cooperation with the door body or door frame in the vertical direction, and the winding roller and the locking mechanism are respectively installed on the mounting part.

[0009] Optionally, the moving component includes: a motor and a rack and pinion mechanism, the gear of the rack and pinion mechanism is connected to the output shaft of the motor, a slide rail is fixed on the door body or door frame, the slide rail extends in a vertical direction, and the rack of the rack and pinion mechanism slides in cooperation with the slide rail.

[0010] Furthermore, the degree of automation is improved. When the temperature detected by the temperature measuring head is higher than the second predetermined value and lower than the first predetermined value, the motor drives the mounting part to move upward a predetermined distance and then downward a predetermined distance through the rack and pinion mechanism.

[0011] Optionally, the mounting portion is refined to make it suitable for the winding roller and the blocking belt. The mounting portion includes a box body, which is slidably connected to the slide rail in the vertical direction. An opening is provided on the side of the box body facing the base. The winding roller is rotatably connected to the box body. A coil spring is connected between the winding roller and the mounting piece. The locking mechanism is connected between the box body and the winding roller, and the blocking belt passes through the opening on the box body.

[0012] Furthermore, it is necessary to provide an adaptive locking mechanism for the winding roller, the locking mechanism includes an electromagnetic brake component, the electromagnetic brake component includes: an electromagnetic coil tube, a rotor and a leaf spring, the electromagnetic coil tube is fixedly connected to the base, and the electromagnetic coil tube is sleeved on one end of the winding roller, the rotor is fixedly sleeved on the winding roller, the rotor is located between the blocking belt wound on the winding roller and the electromagnetic coil tube, one end of the leaf spring is fixedly connected to the side of the rotor facing the electromagnetic coil tube, when the electromagnetic coil is energized to generate a magnetic field, the other end of the leaf spring is magnetically attracted, so that the leaf spring is pressed against the side of the electromagnetic coil tube facing the rotor.

[0013] Furthermore, since the entrance and exit doors of various places and facilities are mostly made of metal, the use of electromagnets can be used as a stable and convenient detachable connection method. Its magnetic attraction is greater than that of a permanent magnet and can be controlled by switching current, which can ensure stable and safe installation and achieve fast and convenient disassembly. The slide rail is provided with installation chambers at both ends of its extension direction, and an electromagnet is provided in the installation chamber, which can be magnetically connected to a door body or door frame including ferromagnetic materials.

[0014] Furthermore, since the mounting part includes a slide rail and a moving mounting part, the power supply for the electromagnetic brake part needs to be adapted to the moving parts and also includes a power supply component. The power supply component includes: a circuit interface, a conductive rail and a conductive brush. The circuit interface is arranged at the lower end of the slide rail for connecting to an external power supply. The conductive rail is parallel to the extension direction of the slide rail. The conductive rail is connected to the slide rail. The conductive rail is electrically connected to the circuit interface. The conductive brush is connected to the side of the box body facing the slide rail. The conductive brush contacts the conductive rail and is electrically connected. The conductive brush is electrically connected to the motor and the conductive brush is electrically connected to the electromagnetic brake part.

[0015] Furthermore, considering that the barrier belt holds the door or blocks the entrance and exit during use, and the locking mechanism locks the winding roller when the visitor's body temperature is detected to be abnormal, this arrangement can block the personnel to a certain extent. However, when the visitor attempts to ignore this blocking mode, the barrier belt is pulled by external force to destroy the barrier belt or the winding roller or the locking mechanism, thereby rendering the pulling effect of the barrier belt on the door ineffective, thereby forcibly opening the door to enter the venue.

[0016] In order to avoid this risk, an alarm component is also included, which includes: an audible and visual alarm and a tension sensor. The tension sensor is connected between the barrier belt and the base. The tension sensor is used to detect the tension value applied to the base by the barrier belt. When the tension value is higher than a predetermined value, the audible and visual alarm is controlled to start to emit an audible and visual alarm signal.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the two mounting parts are detachably connected to the two opposite door bodies, the overall height of the device is adjusted so that the temperature measuring head is at the average height of the human head, the temperature measuring head and the processing module are started to put the device into a standby state, and when a person enters, the head and face are detected by the temperature measuring head to judge the person's body temperature. If the body temperature is normal, the locking mechanism will not work when the person pushes the door, so that the blocking belt can be pulled to overcome the elastic torque of the coil spring so that the blocking belt is pulled out from the winding roller, and will not hinder the door pushing action. If the processing module determines that the body temperature of the person detected by the temperature measuring head is higher than the first predetermined value, it sends a first control signal to the locking mechanism, and the locking mechanism locks the winding roller, so that the blocking belt cannot be pulled out from the winding roller, and the distance between the two door bodies or the door body and the door frame is difficult to change, and people cannot open the door to enter. In the above process, the mounting parts are assembled on various door bodies in a detachable connection manner, and the structure for controlling the door body switch is the blocking belt. The blocking belt can be deformed in all directions. Different from various existing mechanical locks, it is suitable for sliding and swinging doors, flip doors and other types of door bodies, and even open entrances and exits. , can adapt to the different opening and closing methods of these doors, and block open entrances and exits. In essence, it is an additional accessory that can be detachably connected to the door body, rather than an independent gate system. It has good adaptability. During the high incidence of infectious diseases, various places can purchase and install this device to implement temperature detection and control with an automated degree. There is no need to set up a complete access control gate with temperature detection. The door itself is directly endowed with temperature measurement and control functions. If people enter and exit the door, it will inevitably trigger and act on the installation of the winding component and the temperature measuring component, thereby avoiding missed detection problems under the premise of automated operation.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Existing body temperature measurement and control devices are often not well adapted to the entrances and exits of various places / facilities of different specifications. It is impossible to find temperature measuring gate access control equipment that is well adapted to the sizes of the doors / entrances and exits of the places and facilities, which reflects poor adaptability.

[0028] To this end, an embodiment of the present invention provides a body temperature measurement and control device that can be adapted to existing body temperature measurement and control devices of various types of door bodies.

[0029] At least one embodiment of the present invention provides a body temperature measurement and control device, comprising: two installation and winding components and a temperature measuring component connected to the two installation and winding components at the same time, wherein the two installation and winding components are correspondingly installed on two matching door bodies, or, correspondingly installed on matching door bodies and door frames, the temperature measuring component comprises a temperature measuring head and a base, the temperature measuring head is connected to the base, the temperature measuring head is used to detect human body temperature, the installation and winding component comprises: a mounting member, a winding roller, a blocking belt and a locking mechanism, the mounting member is detachably connected to the door body or the door frame, the winding roller is rotatably connected to the mounting member, the blocking belt is connected between the base and the winding roller, the locking mechanism is connected between the mounting member and the winding roller, and can lock or unlock the winding roller, when the human body temperature detected by the temperature measuring head is higher than the first threshold value, the locking mechanism locks the winding roller so that the extension length of the blocking belt remains unchanged, so that the distance between the two door bodies or between the door body and the door frame remains unchanged, and the door cannot be opened.

[0030] In the temperature measurement and control device provided by the above-mentioned embodiment of the present invention, the mounting parts are installed on various door bodies in a detachable connection manner, and the structure for controlling the door body switch is a blocking belt. The blocking belt can be deformed in all directions. Different from various existing mechanical locks, it can adapt to the different opening and closing methods of sliding and swinging doors, flip doors and other types of door bodies, and even open entrances and exits, and block the open entrances and exits. In essence, it is an additional accessory detachably connected to the door body, rather than an independent gate system, and has good adaptability. During the period of high incidence of infectious diseases, various places can purchase and install and use this device to implement temperature detection and control with an automated degree, without the need to set up a complete access control gate with temperature detection.

[0031] The present invention is described below by several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components may be omitted. When any component of the embodiments of the present invention appears in more than one accompanying drawings, the component may be represented by the same reference numeral in each of the accompanying drawings.

[0032] refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a body temperature measurement and prevention device provided by an embodiment of the present invention. Figure 2 A schematic diagram of a body temperature measurement and prevention device provided by an embodiment of the present invention when in use, as shown in FIG. Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a body temperature measurement and prevention and control device, including:

[0033] A body temperature measurement and prevention and control device provided by the present invention comprises: a temperature measuring component, a processing module, an installation and winding assembly, two installation and winding assemblies, and a temperature measuring component connected to the two installation and winding assemblies at the same time, wherein the two installation and winding assemblies are correspondingly installed on two matching door bodies, or, correspondingly installed on matching door bodies and door frames, wherein the temperature measuring component comprises a temperature measuring head 11 and a base 12, the temperature measuring head 11 is connected to the base 12, the processing module is connected to the temperature measuring head 11, the temperature measuring head 11 transmits the detected temperature information to the processing module, the two installation and winding assemblies are distributed on both sides of the temperature measuring component, and the installation and winding assembly comprises: a mounting component 3 , blocking belt 4, winding roller 5, locking mechanism, wherein the mounting member 3 is detachably connected to the door body or door frame, the winding roller 5 is rotatably connected to the mounting member 3, the blocking belt 4 is connected between the base 12 and the winding roller 5, the locking mechanism is connected between the mounting member 3 and the winding roller 5, and can lock or unlock the winding roller 5, the winding spring is connected between the winding roller 5 and the mounting member 3, the processing module is connected to the locking mechanism, when the processing module determines that the human body temperature detected by the temperature measuring head 11 is higher than the first threshold value, the locking mechanism locks the winding roller 5 so that the extension length of the blocking belt 4 remains unchanged, so that the distance between the two door bodies or between the door body and the door frame remains unchanged, and the door cannot be opened.

[0034] Specifically, before use, Figure 1 and Figure 2 As shown, two mounting members 3 are detachably connected to two opposite door bodies. In other embodiments, for a single door body, one mounting member 3 is detachably connected to the door body, and the other mounting member 3 is detachably connected to the door frame opposite to the door body opening and closing position. The overall height of the device is adjusted so that the temperature measuring head 11 is at the average height of the human head. The temperature measuring head 11 and the processing module are started to put the device into a standby state. When a person enters, the head and face are detected by the temperature measuring head 11 to determine the person's body temperature. If the body temperature is normal, the locking mechanism does not work when the person pushes the door, so that the blocking belt 4 can be pulled to overcome the elastic torque of the coil spring so that the blocking belt 4 is pulled out from the winding roller 5, and the door pushing action will not be blocked. If the processing module determines that the body temperature of the person detected by the temperature measuring head 11 is higher than the first preset value, it sends a first control signal to the locking mechanism, and the locking mechanism locks the winding roller 5, so that the blocking belt 4 cannot be pulled out from the winding roller 5, and the distance between the two door bodies (or the distance between the door body and the door frame) is difficult to change, and people cannot open the door to enter, thereby achieving the basic technical effect of temperature measurement and control.

[0035] In the above process, the mounting parts are installed on various door bodies in a detachable connection manner, and the structure used to control the opening and closing of the door body is a blocking belt. The blocking belt can be deformed in all directions. Different from various existing mechanical locks, it can adapt to the different opening and closing methods of sliding and swing doors, flip doors and other types of door bodies, and even open entrances and exits. It can block the open entrances and exits. In essence, it is an additional accessory detachably connected to the door body, rather than an independent gate system. It has good adaptability and directly gives the door itself a temperature measurement and control function. If people enter and exit the door, it will inevitably trigger and act on the installed winding components and temperature measuring components, thereby avoiding missed detection problems under the premise of automated operation.

[0036] Moreover, each place can purchase and install the present embodiment to perform automated temperature detection and control during the high incidence of infectious diseases, without the need to set up a complete access control gate with temperature detection, thereby saving design and customization costs.

[0037] In various embodiments, the mounting member 3 can adopt various mounting base structures and can be detachably connected to the door body or the entrance and exit, such as a box body bonded to the door body, a block magnetically attached to the metal door frame, or a shell locked on the door handle with a fastening hoop or fastening screws.

[0038] Furthermore, considering that although the barrier belt 4 is arranged near the height of the human head to ensure that the temperature measuring head 11 can measure the temperature of the human forehead, even if the body temperature of the person is normal, the locking mechanism unlocks the winding roller 5 so that the door body can be pushed, but the person still needs to lower his head and bypass the barrier belt 4 to pass, which has a counter-effect on the prevention and control process. Therefore, the mounting part 3 includes: a mounting part and a moving component that drives the mounting part to move, the mounting part slides in cooperation with the door body or door frame in the vertical direction, and the winding roller 5 and the locking mechanism are respectively installed on the mounting part.

[0039] Specifically, the moving component includes: a motor 32 and a gear rack mechanism, the gear 33 of the gear rack mechanism is connected to the output end shaft of the motor 32, a slide rail 31 is fixed on the door body or door frame, the slide rail 31 extends in the vertical direction, and the rack 34 of the gear rack mechanism slides with the slide rail 31.

[0040] Through the above-mentioned settings, by refining the installation part 3, the barrier belt 4 can move in the vertical direction along with the installation part. After judging that the body temperature of the person is normal, the motor can be used to drive the installation part to move, thereby changing the height of the barrier belt 4, so that people do not need to lower their heads to pass through the barrier belt.

[0041] In order to further improve the prevention and control effect and avoid missed detection, the processing module is configured so that when the processing module determines that the temperature detected by the temperature measuring head 11 is higher than the second predetermined value and less than the first predetermined value, the processing module sends a second control signal to the motor 32, so that the motor 32 drives the mounting part to move upward a predetermined distance and then downward a predetermined distance through the gear rack mechanism.

[0042] In this embodiment, the second predetermined value should be the average value of the ambient temperature. In different temperature environments and seasons, the second predetermined value needs to be changed and reset. For example, the second predetermined value in summer can be set to 35 degrees Celsius, and the second predetermined value in winter can be set to 10 degrees Celsius. The first predetermined value is the high body temperature warning temperature, which is set to 37.5 degrees Celsius. By setting the second predetermined value, it is possible to avoid the environmental objects from erroneously triggering the temperature measuring head 11, so that the processing module mistakenly determines that a person with a body temperature lower than the first predetermined value (high body temperature warning temperature) is within the temperature measuring range of the temperature measuring head 11.

[0043] In some embodiments, a temperature measuring head 11 with a narrow temperature measuring range and limited distance can also be used to avoid the temperature measuring head being mistakenly triggered by environmental objects. In this embodiment, the second preset value may not be set. When the temperature detected by the temperature measuring head 11 is less than the first preset value, a second control signal can be sent to the motor 32.

[0044] The processing module sends a second control signal to the motor 32, the purpose of which is to make the barrier belt 4 give way to people with normal body temperature to enter and exit the door, by making the motor 32 drive the mounting part to move upward a predetermined distance and then move downward a predetermined distance through the gear rack mechanism, so that the barrier belt 4 moves upward to avoid the movement path of the people, leaving time for the people to move, and then moves downward to reset to the original position. In this embodiment, the original position height of the barrier belt 4 is set to 1.65m, so that the forehead of most people can be within the temperature measurement range of the temperature measuring head 11, and people with extremely high heights can enter the temperature measurement range of the temperature measuring head 11 by standing on tiptoe or bending over.

[0045] In another embodiment, the processing module controls the motor 32 so that it drives the barrier belt 4 to move up and down in a small range in the standby state. Preferably, the barrier belt 4 moves back and forth slowly between 1.4m and 2m above the ground, so that the temperature of people of all heights can be measured.

[0046] In each embodiment, after the processing module sends the second control signal to the motor 32, the barrier belt 4 moves to a maximum height of 2 m above the ground, thereby enabling most people to pass through.

[0047] Furthermore, the mounting portion is refined to be adapted to the winding roller 5 and the blocking belt 4. Specifically, the mounting portion includes a box body 35, which is slidably connected to the slide rail 31 along the vertical direction. The box body 35 has an opening on the side facing the temperature measuring component. The winding roller 5 is rotatably connected to the box body 35. The locking mechanism is connected between the box body 35 and the winding roller 5, and the blocking belt 4 passes through the opening on the box body 35.

[0048] Furthermore, in order to further improve the prevention and control effect, strengthen the locking ability of the locking mechanism, and avoid missed detection, it is necessary to set a strong locking mechanism for the winding roller 5. Specifically, the locking mechanism includes: an electromagnetic brake 6, including: an electromagnetic coil tube 61, fixedly connected to the inner wall of the box body 35, and the electromagnetic coil tube 61 is sleeved on one end of the winding roller 5; a rotor 62, fixedly sleeved on the winding roller 5, and the rotor 62 is located between the blocking belt 4 wound on the winding roller 5 and the electromagnetic coil tube 61; a leaf spring 63, one end of which is fixedly connected to the side of the rotor 62 facing the electromagnetic coil tube 61, and when the electromagnetic coil is energized to generate a magnetic field, the other end of the leaf spring 63 is magnetically attracted, so that the leaf spring 63 is against the side of the electromagnetic coil tube 61 facing the rotor 62. The electromagnetic brake component 6 can brake the winding roller 5 in a timely and stable manner. When the processing module determines that the temperature detected by the temperature measuring head 11 is higher than the first predetermined value, it sends a first control signal to the locking mechanism, thereby starting and energizing the electromagnetic coil, generating a magnetic field to magnetically attract the other end of the leaf spring 63, so that the leaf spring 63 presses against the side of the electromagnetic coil tube 61 facing the rotor 62, thereby braking the winding roller 5 with friction force.

[0049] In another embodiment, the locking mechanism includes a linear motor and an abutment plate driven by the linear motor. When the processing module sends a first control signal, the linear motor is started to drive the abutment plate, so that the abutment plate presses against the side or bottom surface of the winding roller 5 to brake the winding roller 5 with friction.

[0050] In other embodiments, other forms of electric locking mechanisms may also be used, such as a matching structure of an electric locking hoop or an electric locking rod and a locking groove provided on the winding roller 5 .

[0051] Furthermore, this embodiment provides a detachable connection method between a mounting member 3 and a door body or door frame. Specifically, the slide rail 31 is provided with mounting chambers at both ends in its extension direction. An electromagnet 311 is provided in the mounting chamber. The electromagnet 311 can be magnetically connected to a door body or door frame comprising ferromagnetic material.

[0052] Since the entrance and exit gates of various places and facilities are mostly made of metal, the use of electromagnets can be used as a stable and convenient detachable connection method. The magnetic attraction is greater than that of permanent magnets and can be controlled by switching current, which can not only ensure stable and safe installation, but also achieve fast and convenient disassembly, thereby further improving the adaptability of the device to various types of gates, and improving the prevention and control effect of the gate with a more adaptable and stable setting method, avoiding missed detection.

[0053] Furthermore, considering that the electromagnetic brake component 6 in the present embodiment is an electrical component, if its electrical circuit adopts the form of conventional wires, since the mounting component 3 includes the slide rail 31 and the moving mounting part, the wires will gradually wear, deform, or even fail during the movement, thereby destroying the prevention and control effect and causing the missed detection problem that should be avoided. Therefore, the power supply for the electromagnetic brake component 6 needs to be adapted to the moving parts. Specifically, it also includes a power supply component 7, which includes: a circuit interface 71, which is arranged at the lower end of the slide rail 31 and is used to connect to an external power supply; a conductive rail 72, which is parallel to the extension direction of the slide rail 31 and is connected to the slide rail 31, and the conductive rail 72 is electrically connected to the circuit interface 71; a conductive brush 73, which is connected to the side of the box body 35 facing the slide rail 31, and the conductive brush 73 contacts the conductive rail 72 to be electrically connected, and the conductive brush 73 is electrically connected to the motor 32, and the conductive brush 73 is electrically connected to the electromagnetic brake component 6.

[0054] The above arrangement ensures that even when the box body 35 is in motion, since the extension direction of the conductive rail 72 is consistent with the movement direction of the box body 35, the conductive brush 73 connected to the box body 35 always maintains electrical contact with the conductive rail 72, thereby being able to supply power to the electromagnetic brake component 6 in the box body 35.

[0055] Furthermore, the mounting portion further includes: a roller 36 , which is disposed on a side of the box body 35 facing the slide rail 31 , and the roller 36 abuts against an inner wall of the slide rail 31 .

[0056] Furthermore, considering that the barrier belt holds the door or blocks the entrance and exit during use, and the locking mechanism locks the winding roller 5 when the visitor's body temperature is detected to be abnormal, this arrangement can block the personnel to a certain extent according to social norms. However, when the visitor attempts to ignore this blocking mode, the barrier belt 4 is pulled by external force to destroy the barrier belt 4 or the winding roller 5 or the locking mechanism, thereby rendering the pulling effect of the barrier belt 4 on the door ineffective, thereby forcibly opening the door to enter the venue.

[0057] In order to avoid this risk, further enhance the highly adaptable prevention and control capabilities, and avoid the problem of missed detection due to violent door opening, the present embodiment also includes an alarm component, which includes: an audible and visual alarm connected to the processing module; a tension sensor 8 connected between the barrier strip 4 and the base 12, and the tension sensor 8 is connected to the processing module, for detecting the magnitude of the tension applied by the barrier strip 4 to the base 12 and transmitting the tension information to the processing module. When the processing module determines that the magnitude of the tension detected by the tension sensor 8 is higher than a predetermined value, the audible and visual alarm is controlled to start to emit an audible and visual alarm signal.

[0058] Specifically, when the visitor's body temperature is normal, the locking mechanism does not lock the winding roller 5, and the visitor can push the door to pull the blocking belt 4 to open the door body. At this time, the tension between the blocking belt 4 and the base 12 is small and lower than the predetermined value, so the sound and light alarm will not be triggered. When the visitor's body temperature is too high, the locking mechanism locks the winding roller 5, so that the blocking belt 4 will not be rolled out from the winding roller 5 due to pulling. At this time, if the visitor uses external force to forcibly push the door, a large pulling force will be generated on the blocking belt 4, which will be reflected in the magnitude of the pulling force between the blocking belt 4 and the base 12. The pulling force detected by the tension sensor 8 is higher than the predetermined value, and the processing module will control the sound and light alarm to start, warn the person who forcibly enters, and remind the relevant security personnel.
