Description

Technical Field

[0001] The utility model relates to the technical field of security equipment, and particularly relates to an intrusion alarm device. Background Art

[0002] With the rapid development of the construction of modern industrial parks, smart parks have become an important part of future urban management and operation. Smart parks rely on cutting-edge technologies such as the Internet of Things (IoT), big data, and artificial intelligence (AI). Through efficient management and monitoring systems, they achieve the optimal allocation and efficient utilization of resources within the park. There are a large number of tangible and intangible assets in smart parks. To ensure the security of these assets, smart parks usually set up a large number of security measures to ensure the safety of the park. This includes using a large number of monitors to monitor the entire park, and using environmental sensors to monitor the environmental data of each area within the park. For the boundaries of the park, most are protected by enclosing walls. However, to prevent people from invading the park by climbing over the walls, intrusion prevention or intrusion alarm devices are usually set on the enclosing walls of the park to further enhance the security performance of the walls.

[0003] For example, Chinese Utility Model Patent No. CN202322515975.5 discloses a perimeter intrusion alarm system, which includes a perimeter intrusion alarm host, a monitoring and sensing device, and a fusion alarm display device. The monitoring and sensing device is communicatively connected to the perimeter intrusion alarm host, and the fusion alarm display device is communicatively connected to the perimeter intrusion alarm host; the monitoring and sensing device at least includes a vibration optical cable and a thermal imaging camera. The vibration optical cable and the thermal imaging camera are evenly arranged on the perimeter wall or fence; the vibration optical cable and the thermal imaging camera simultaneously collect the intrusion signals of the perimeter wall or fence, and jointly judge perimeter intrusion through the optical signal of the vibration optical cable and the image signal of the thermal imaging camera, improving the accuracy of the alarm, reducing the workload of personnel, and being suitable for the layout and control of natural gas purification plants in complex outdoor environments. When using this fence intrusion alarm system, when the alloy wire on the upper side of the wall is touched by a person or an object, an alarm will be triggered, and a feeling of electric shock will be generated to block and deter the intruder.

[0004] In the prior art, as in the above-mentioned disclosed patents, most park enclosing walls adopt similar security measures, using fences in combination with sensors, cables and other facilities to monitor and prevent others from invading the park by climbing over the walls. However, such a setting method not only requires a large number of cables to be laid, resulting in a high cost of the entire intrusion alarm system, but also has a relatively high maintenance cost during daily maintenance. Moreover, it is troublesome to repair after the cable is damaged. In addition, using electric current to prevent intrusion is likely to cause accidental injury to animals staying on the wall. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an intrusion alarm device, which solves the problems in the prior art that the intrusion alarm system is expensive in cost and very troublesome to maintain by arranging a large number of vibration optical cables and conductive alloy wires to form a fence to form an intrusion alarm system.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions:

[0007] An intrusion alarm device includes an infrared projector and an infrared receiver that cooperate with each other, and further includes a mounting post and a pressing block. A first mounting groove is provided on one side of the mounting post, and the infrared projector is installed in the first mounting groove. A pressure groove is provided at the top of the mounting post, and a pressure sensor is installed at the bottom of the pressure groove. A trigger block matching the pressure groove is provided on the lower side of the pressing block, and the trigger block is movably arranged in the pressure groove and is in contact with the pressure sensor; a second mounting groove is provided on the side of the pressing block facing the same side of the first mounting groove, and a monitoring camera is installed in the second mounting groove; the monitoring camera, the infrared projector, the infrared receiver, and the pressure sensor are all connected to a remote control device through a wired or wireless network.

[0008] A further technical solution is that the edge of the lower side of the pressing block is connected to the edge of the upper end of the mounting post through a rubber sheet.

[0009] A further technical solution is that a supplementary light and a horn unit are further installed above the monitoring camera in the second mounting groove.

[0010] A further technical solution is that a third mounting groove is provided on the opposite side of the first mounting groove of the mounting post, and the infrared receiver is detachably installed in the third mounting groove.

[0011] A further technical solution is that a first light-transmitting plate is provided at the notch of the first mounting groove, a second light-transmitting plate is provided at the notch of the second mounting groove, and a third light-transmitting plate is provided at the notch of the third mounting groove.

[0012] A further technical solution is that a first mounting plate is provided at the lower end of the mounting post, and a first mounting hole penetrating through the upper and lower sides is provided on the first mounting plate.

[0013] A further technical solution is that a second mounting plate is provided at the lower end of the infrared receiver, a second mounting hole penetrating through the upper and lower sides is provided at a position near the edge of the second mounting plate, a threaded hole is provided on the lower side of the second mounting plate, an internal thread of the threaded hole is matched and connected with a support threaded rod, the lower end of the support threaded rod extends below the second mounting plate, and is connected with a third mounting plate.

[0015] Compared with the prior art, the utility model has at least one of the following beneficial effects: 1. By setting an infrared projector and an infrared light receiver, an infrared grating can be formed in cooperation. When a person or an object blocks between the infrared projector and the infrared light receiver and affects the infrared light receiver's reception of light, an alarm signal will be sent to the remote controller; 2. By setting a pressing block and a pressure sensor, when someone tries to climb over the mounting post by holding the top of the pressing block, thus avoiding triggering the infrared grating, the pressure on the pressure sensor will cause the remote controller to send an alarm signal; 3. By setting a monitoring camera, daily video monitoring can be carried out, so as to capture the picture when someone climbs over between the infrared projector and the infrared light receiver, and when a bird or an animal accidentally touches and causes the remote controller to send an alarm signal, the captured picture can be used by security personnel to judge whether treatment is needed; 4.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0021] Figures 1 to 3 The following shows an embodiment of the utility model.

[0022] Embodiment:

[0023] An intrusion alarm device includes an infrared projector 1 and an infrared receiver 2 that cooperate with each other, and also includes a mounting post 3 and a pressing block 4. A first mounting groove 5 is provided on one side of the mounting post 3, and the infrared projector 1 is installed in the first mounting groove 5. A pressure groove 6 is provided at the top of the mounting post 3, and a pressure sensor 7 is installed at the bottom of the pressure groove 6. A trigger block 8 that matches the pressure groove 6 is provided on the lower side of the pressing block 4. The trigger block 8 is movably arranged in the pressure groove 6 and is in contact with the pressure sensor 7. On the side of the pressing block 4 facing the same side of the first mounting groove 5, a second mounting groove 9 is provided, and a monitoring camera 10 is installed in the second mounting groove 9. The monitoring camera 10, the infrared projector 1, the infrared receiver 2, and the pressure sensor 7 are all connected to a remote control device through a wired or wireless network. By providing the infrared projector 1 and the infrared receiver 2, an infrared grating can be formed in cooperation. When a person or an object blocks between the infrared projector 1 and the infrared receiver 2 and affects the infrared receiver 2's reception of light, an alarm signal will be sent to the remote controller. By providing the pressing block 4 and the pressure sensor 7, when someone tries to climb over the mounting post 3 by holding the top of the pressing block 4, thus avoiding triggering the infrared grating, a pressure will be generated on the pressure sensor 7, causing the remote controller to send an alarm signal. By providing the monitoring camera 10, daily video monitoring can be carried out, so as to capture the picture when someone climbs over between the infrared projector 1 and the infrared receiver 2, and when a bird or an animal accidentally touches and causes the remote controller to send an alarm signal, the security personnel can judge whether treatment is needed through the captured picture.

[0024] The edge of the lower side of the pressing block 4 is connected to the edge of the upper end of the mounting post 3 through a rubber sheet 11. By providing the rubber sheet 11, not only can the edge gap between the pressing block 4 and the mounting post 3 be sealed to prevent impurities or rainwater from entering the pressure groove 6. At the same time, it can also be used as a connecting piece to fix the pressing block 4 on the upper side of the mounting post 3. Further, in order to improve the sealing performance, a rubber sealing ring is provided around the edge of the pressure groove 6 to seal the gap between the pressing block 4 and the mounting post 3.

[0025] A supplementary light 12 and a speaker unit are also installed above the monitoring camera 10 in the second mounting groove 9. By providing the supplementary light 12, when an alarm occurs at night, the area photographed by the monitoring camera 10 can be illuminated by the supplementary light 12, thereby improving the clarity of the picture taken, so that the invading object or person can be photographed clearly.

[0026] The installation post 3 is provided with a third installation groove 13 on the opposite side of the first installation groove 5, and the infrared light receiver 2 is detachably installed in the third installation groove 13. When the length of the enclosure is short, one installation post 3 and one infrared light receiver 2 can be respectively arranged at the two end parts on the upper side of the enclosure. However, when the length of the enclosure is long, a plurality of infrared light emitters 1 and infrared light receivers 2 need to be arranged continuously. Therefore, at the middle position, the adjacent infrared light receiver 2 and infrared light emitter 1 are installed through one installation post 3, which can not only protect the infrared light receiver 2 and the infrared light emitter 1, but also perform intrusion prevention on the position where the infrared light receiver 2 and the infrared light emitter 1 are installed in the middle by means of the pressing block 4 and the pressure sensor 7.

[0027] A first light-transmitting plate 14 is arranged at the notch of the first installation groove 5, a second light-transmitting plate 15 is arranged at the notch of the second installation groove 9, and a third light-transmitting plate 16 is arranged at the notch of the third installation groove 13. By arranging the first light-transmitting plate 14, rainwater and impurities can be prevented from entering the first installation groove 5, and light can be allowed to pass through. By arranging the second light-transmitting plate 15, rainwater and impurities can be prevented from entering the second installation groove 9, and light can be allowed to pass through. By arranging the third light-transmitting plate 16, rainwater and impurities can be prevented from entering the third installation groove 13, and light can be allowed to pass through.

[0028] The lower end of the installation post 3 is provided with a first installation plate 17, and a first installation hole 18 penetrating through the upper and lower sides is arranged on the first installation plate 17. By arranging the first installation plate 17 and the first installation hole 18, the installation post 3 can be conveniently installed on the upper side of the enclosure.

[0029] The lower end of the infrared light receiver 2 is provided with a second installation plate 19. A second installation hole penetrating through the upper and lower sides is arranged at a position close to the edge of the second installation plate 19. A threaded hole 20 is arranged on the lower side of the second installation plate 19, and an internal thread of the threaded hole 20 is in threaded connection with a support threaded rod 21. The lower end of the support threaded rod 21 extends below the second installation plate 19 and is connected with a third installation plate 22. When the length of the enclosure is short and only one set of infrared light receiver 2 and infrared light emitter 1 needs to be installed, the infrared light emitter 1 is installed through the installation post 3, while the infrared light receiver 2 is installed separately. At this time, since there is a certain height difference between the installation height of the infrared light receiver 2 and the installation height of the infrared light emitter 1, in order to make up for the height difference, the height difference can be made up by arranging the support threaded rod 21 and the third installation plate 22.

[0030] A connection hole 23 is arranged at the top of the pressing block 4, and an anti-bird thorn is installed on the upper side of the pressing block 4 through the connection hole 23. By arranging the anti-bird thorn, it can be avoided that birds stay on the pressing block 4, resulting in the trigger block 8 of the pressing block 4 pressing the pressure sensor 7 to send an alarm to the remote control device.
