[0002] Unmanned security booths are a new type of security facility that has gradually emerged in recent years with the development of intelligent and automated technologies. This type of booth integrates various advanced technical means, such as video surveillance, access control systems, and intelligent identification, to achieve security monitoring and management of the area without the need for traditional security personnel to be on duty 24 hours a day.

[0003] However, since this unmanned security booth is not manned by a dedicated person, its flexibility is low. Some people without passage permit can directly cross the barrier and enter the protection area protected by the unmanned security booth. This unmanned security booth manages the entry and exit and charging of vehicles through technologies such as intelligent vehicle recognition. However, under some specific operations, such as vehicles following too closely or drivers taking advantage of the time difference in the barrier lifting when the front vehicle pays the fee and passing quickly behind the front vehicle, the rear vehicle will evade payment, thereby causing economic losses. Therefore, it does not meet the existing needs. We have proposed an unmanned security booth for this purpose. Summary of the invention

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figures 1 to 6 , an embodiment provided by the present invention: an unmanned security booth, comprising a security booth 1, a high-security comprehensive protection alarm mechanism is fixedly installed on one side of the outer surface of the security booth 1, the high-security comprehensive protection alarm mechanism comprises two gates 3, two gate rods 4, two roller bearing circular plates 11, two lockable fixing mechanisms, a gate mounting base 5 and an alarm light B27, the two roller bearing circular plates 11 are respectively fixed to the lower end surfaces of the two gates 3, the first roller bearing circular plate 11 from front to back is located inside the security booth 1, the second roller bearing circular plate 11 from front to back is located inside the gate mounting base 5, and the two roller bearing circular plates 11 are connected to the security booth 1 and the gate mounting base 5 through roller bearings; The two barrier poles 4 are respectively installed on the outer surfaces of the two barrier poles 3. A fixed bracket B9 is fixedly provided on both sides of the front end of the barrier pole 4. An infrared head 10 is fixedly provided on the rear end face of the fixed bracket B9. A fixed bracket A7 is fixedly provided on both sides of the rear end of the barrier pole 4. An infrared receiver 8 is fixedly provided on the front end face of the fixed bracket A7. The position of the fixed bracket A7 corresponds to the position of the infrared receiver 8, and all the infrared receivers 8 are electrically connected to the alarm light B27.

[0020] Specifically, the high-security comprehensive protection alarm mechanism also includes a barrier gate support platform 6, which is fixed to the upper end surface of the barrier gate mounting base 5, and the rear end surface of the first barrier gate rod 4 from front to back is located inside the barrier gate support platform 6; before installing the equipment, the barrier gate support platform 6 fixed to the upper end surface of the barrier gate mounting base 5 is aligned with the barrier gate rod 4 installed on the first barrier gate 3 from front to back, and then the barrier gate mounting base 5 is fixed at this position. When the barrier gate mounting base 5 is fixed, the rear end of the first barrier gate 3 is placed inside this barrier gate support platform 6, and then a new barrier gate mounting base 5 is picked up, and the barrier gate support platform 6 fixed on this barrier gate mounting base 5 is aligned with the barrier gate rod 4 on the barrier gate 3 on the already installed barrier gate mounting base 5, and then this barrier gate mounting base 5 is fixed at this position and connected to the barrier gate rod 4 through the barrier gate support platform 6. Through the above technical solution, multiple barrier gate rods 4 can be connected to each other, thereby increasing the detection range of the security booth 1 itself.

[0021] Since the barrier gate 3 is mounted on the barrier gate mounting base 5 through the roller bearing circular plate 11, the barrier gate 3 itself can adjust its own angle by rotation. When the angle of the barrier gate 3 itself changes, the position of the barrier gate rod 4 installed on its outer surface will also change accordingly. Through the above technology, the barrier gate rod 4 can be installed according to the shape of the required protection area, thereby improving the flexibility of the equipment.

[0022] Please continue reading Figures 1 to 6 Specifically, the lockable fixing mechanism includes a manually rotating circular plate 12, a circle of fixing heads 13 are fixedly provided on the outer side of the lower end surface of the manually rotating circular plate 12, and a fixing groove 14 located inside the roller bearing circular plate 11 is provided on the outer side of the fixing head 13, and the fixing head 13 is stuck in the inside of the fixing groove 14; when the angle of the gate 3 is changed according to the shape of the required protection area, the manually rotating circular plate 12 is pulled upward first, and as the manually rotating circular plate 12 rises, the fixing head 13 fixed thereto will leave the inside of the fixing groove 14, and only when the fixing head 13 completely leaves the inside of the fixing groove 14, the manually rotating circular plate 12 can be rotated.

[0023] A synchronization shaft 16 is provided below the manual rotating circular plate 12, a square groove 17 is provided in the middle of the upper end surface of the synchronization shaft 16, and a square rod 15 is provided inside the square groove 17 to fix the upper end surface of the synchronization shaft 16 and the manual rotating circular plate 12; The inner wall cross-section of the square groove 17 is a square, the outer surface of the square rod 15 fits with the inner wall of the square groove 17, and the square rod 15 and the square groove 17 are slidingly connected; when the manually rotating circular plate 12 rotates, the square rod 15 fixed on its lower end surface will rotate together, and because the outer surface of the square rod 15 fits with the inside of the square groove 17 located on the upper end surface of the synchronization shaft 16, when the square rod 15 rotates, the synchronization shaft 16 will rotate therewith.

[0024] A synchronous sprocket 18 is provided on one side of the synchronous shaft 16 , and the synchronous shaft 16 and the synchronous sprocket 18 are connected in series via a synchronous chain 19 ; the rotating synchronous shaft 16 will drive the synchronous sprocket 18 to rotate together via the synchronous chain 19 .

[0025] A circular plate 26 is fixedly provided on the lower end surface of the synchronous sprocket 18, and an internal thread groove 20 is provided below the circular plate 26. An inclined internal thread ring 21 matching its internal thread is provided inside the internal thread groove 20, and a vertically movable synchronous rod 22 penetrating the inclined internal thread ring 21 is fixedly provided on both sides of the lower end surface of the circular plate 26; when the synchronous sprocket 18 rotates, the circular plate 26 fixed thereto will also rotate accordingly. When the circular plate 26 rotates, the inclined internal thread ring 21 penetrated by the two synchronous rods 22 fixed to the lower end surface of the circular plate 26 will rotate together, and the rotating inclined internal thread ring 21 can be moved up and down through the internal thread transmission of the internal thread groove 20, and the inclined internal thread ring 21 is moved downward at this time.

[0026] An arc-shaped tooth row 23 is provided on both sides below the bevel internal thread ring 21, and the surface of the bevel internal thread ring 21 facing the arc-shaped tooth row 23 and the surface of the arc-shaped tooth row 23 facing the bevel internal thread ring 21 are both inclined surfaces, the lower end surface of the arc-shaped tooth row 23 is slidably connected to the inside of the roller bearing circular plate 11, and a reset spring 25 is connected to one side of the outer surface of the bottom end of the arc-shaped tooth row 23; as the bevel internal thread ring 21 descends, the bevel internal thread ring 21 will contact the arc-shaped tooth row 23 and push the arc-shaped tooth row 23 outward, and as the arc-shaped tooth row 23 moves, the arc-shaped tooth row 23 will squeeze the reset spring 25; A fixed inner gear ring 24 is provided on the outer sides of the two arc-shaped gear rows 23, and the ends of the tooth heads on the arc-shaped gear rows 23 and the fixed inner gear ring 24 are both arc-shaped; as the arc-shaped gear rows 23 move, the arc-shaped gear rows 23 will mesh with the fixed inner gear ring 24 to fix the roller bearing circular plate 11. When the roller bearing circular plate 11 is fixed, the angle of the gate 3 installed on the upper end surface of the roller bearing circular plate 11 will also be fixed. By fixing the angle of the gate 3, it can be prevented from rotating without authorization due to external conditions; Since the top ends of the teeth on the arc-shaped tooth row 23 and the fixed inner tooth ring 24 are both arc-shaped, even if the teeth on the outer surface of the arc-shaped tooth row 23 collide with the teeth on the inner wall of the fixed inner tooth ring 24, they will intersect and mesh with each other due to their arc-shaped surfaces.

[0027] When the angle of the barrier 3 is fixed, the fixing head 13 fixed to the lower end surface of the manually rotating circular plate 12 is aligned with the fixing groove 14, and then the fixing head 13 is inserted into the fixing groove 14 to lock the manually rotating circular plate 12 to prevent it from rotating, thereby causing the fixing structure to loosen.

[0028] When it is necessary to release the angle of the barrier gate 3, the manual rotating circular plate 12 is rotated in the opposite direction to move the inclined internal thread ring 21 upward. As the inclined internal thread ring 21 rises, the arc-shaped tooth row 23 is gradually pushed back to its original position through the reaction force of the squeezed return spring 25, thereby releasing the fixation of the barrier gate 3.

[0029] There is an infrared ray emitted by the infrared head 10 above and below each barrier pole 4, and this infrared ray is received by the infrared receiver 8. If a person without permission wants to directly cross the barrier pole 4 or drill under the barrier pole 4, the infrared ray will be blocked. When the infrared ray is blocked, the alarm light B27 electrically connected to the infrared receiver 8 will automatically sound an alarm to remind the patrol personnel that something has happened and to come and check it out quickly. The above technical solution improves the safety strength of the equipment and prevents illegal entry by outsiders.

[0030] A mechanism 2 to prevent toll evasion by following a vehicle is provided on one side of the security booth 1. The mechanism 2 to prevent toll evasion by following a vehicle includes a concave bracket A202, an alarm light A203, a concave vehicle guide rod 216, a moving mechanism and multiple monitoring cameras 204. The alarm light A203 is fixed to the surface of the concave bracket A202 facing the barrier rod 4. Multiple monitoring cameras 204 are all fixedly installed on the upper side of the concave bracket A202, and the monitoring cameras 204 and the alarm light A203 are electrically connected by signals. The position of the concave vehicle guide rod 216 corresponds to the position of the concave bracket A202, and the concave vehicle guide rod 216 can be moved up, down, left and right by the moving mechanism.

[0031] Please continue reading Figures 1 to 6The mobile mechanism provided by the present invention includes two slide rails 201, and the upper end surfaces of the two slide rails 201 are each installed with an intelligent electric slide 205, and the two sides of the lower end surface of the concave bracket B206 are respectively fixed between the two intelligent electric slides 205; when a vehicle wants to pass through the security booth 1 and the vehicle license plate is recognized by the security booth 1, the gate rod 4 will be lifted, and then when the vehicle passes through the lifted gate rod 4 and enters between the two slide rails 201, as the vehicle moves forward, the intelligent electric slide 205 will also move along the slide rails 201, and as the intelligent electric slide 205 moves, it is fixed to the two intelligent The concave bracket B206 on the upper end surface of the electric slide 205 and the concave vehicle guide rod 216 connected to the outer surface of the concave bracket B206 will move together. As the concave vehicle guide rod 216 moves, the concave vehicle guide rod 216 will provide a space for the vehicle to move forward until it completely passes through the raised barrier pole 4. If a vehicle wants to evade the toll and forcibly enter under the raised barrier pole 4 at this time, it will be detected by the monitoring camera 204. At this time, the concave vehicle guide rod 216 will stop moving, and the alarm light A203 will sound an alarm to prompt the staff to come and deal with it.

[0032] Furthermore, a stepper motor 207 is fixedly installed on the upper side of the concave bracket B206, and the output shaft of the stepper motor 207 is connected to the transmission shaft 208 through a coupling. The lower side fixed sleeve of the outer surface of the transmission shaft 208 is provided with a bevel gear A209, and both sides of the outer surface of the bevel gear A209 are meshed with a bevel gear B210, and the axis of the bevel gear B210 is connected to the rotating shaft 211, and one side of the outer surface of the rotating shaft 211 is fixedly provided with a bevel gear C212, and the bevel gear C212 is meshed with a bevel gear D213, and the axis of the bevel gear D213 is connected to a threaded rod 214, and the lower side sleeve of the outer surface of the threaded rod 214 is provided with an internal thread sleeve 215 matching its external thread, and the surfaces of the concave guide rod 216 facing the two internal thread sleeves 215 are fixed between the internal thread sleeves 215.

[0033] In actual application, the stepper motor 207 will only be started when the vehicle that cuts in leaves from under the lifted barrier pole 4, returns to its original position and the lifted barrier pole 4 becomes parallel again. The stepper motor 207 can drive the transmission shaft 208 connected thereto and the bevel gear A209 fixedly mounted on the outer surface of the transmission shaft 208 to rotate. When the bevel gear A209 rotates, the two bevel gears B210 meshing therewith will rotate together. When the bevel gear B210 rotates, the shaft 211 connected to the axis of the bevel gear B210 and the bevel gear C212 fixedly mounted on the outer surface of the shaft 211 will rotate accordingly. The rotating bevel gear C212 can drive the bevel gears meshing therewith. D213 and the threaded rod 214 connected to the axis of the bevel gear D213 rotate. When the threaded rod 214 rotates, the internal threaded sleeve 215, which is sleeved on the outer surface of the threaded rod 214 and is threadedly connected to it but cannot rotate by itself, will move up and down under the transmission of the threaded structure. At this time, the internal threaded sleeve 215 moves upward, and as the internal threaded sleeve 215 rises, the concave vehicle guide rod 216 fixed between the two internal threaded sleeves 215 will move upward together. When the concave vehicle guide rod 216 is higher than the vehicle that has passed through the barrier rod 4, the vehicle that has passed through the barrier rod 4 can drive out, and then the concave vehicle guide rod 216 will automatically move downward and return to its original position. The above technical solution can prevent the situation of following the vehicle to evade the fee.

[0034] In actual application, a metal cover plate located on the upper end surface of the concave bracket B206 is provided above the stepper motor 207, and the concave bracket B206 and the metal cover plate are fixed by screws; the metal cover plate can protect the stepper motor 207, and when the stepper motor 207 fails, the stepper motor 207 can be repaired by removing the metal cover plate.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
