Description

Technical Field

[0001] The present invention relates to the technical field of security and defense, and in particular to an intelligent tear gas security system. Background Art

[0002] With the continuous and rapid development of the national economy and the steady improvement of the income level of residents, the safety of life and property has been increasingly emphasized by people. Using high-tech to carry out security prevention has become an inevitable trend in the development of security.

[0003] At present, with the upgrade of the bank security system, in order to effectively prevent theft and robbery incidents, in addition to installing cameras and alarms inside the bank, security measures such as tear gas bombs are also adopted. Once an abnormal event occurs, by detonating the tear gas bomb to release tear gas, it can force criminals to abandon their criminal acts. However, the tear gas equipment currently used in banks can only be set for a single area, and cannot provide all-round protection for each area of the bank, and cannot meet the requirements of comprehensiveness, intelligence, and reliability of the bank security system. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent tear gas security system, which can provide all-round security protection for the bank and ensure the stability and reliability of the security system.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] An intelligent tear gas security system includes a cash replenishment area detection and tear gas component, a customer area detection and tear gas component, a business hall detection and tear gas component, a control host, and a monitoring terminal. The cash replenishment area detection and tear gas component includes a door magnetic switch, an infrared pair sensor, a first camera, and a first tear gas emitter. The customer area detection and tear gas component includes a vibration sensor, a sound sensor, a second camera, and a second tear gas emitter. The business hall detection and tear gas component includes a third camera and a third tear gas emitter. The control host includes a detection signal receiving module, a tear gas trigger module, a network communication module, a power supply module, and a microcontroller. The output ends of the door magnetic switch, the infrared pair sensor, the vibration sensor, and the sound sensor are respectively electrically connected to the input end of the detection signal receiving module. The output end of the detection signal receiving module is electrically connected to the input end of the microcontroller. The input ends of the first tear gas emitter, the second tear gas emitter, and the third tear gas emitter are respectively electrically connected to the output end of the tear gas trigger module. The input end of the tear gas trigger module is electrically connected to the output end of the microcontroller. The first camera, the second camera, and the third camera are respectively connected to the monitoring terminal through the RS485 bus. The microcontroller is connected to the monitoring terminal through the network communication module. The power supply module supplies power to the detection signal receiving module, the network communication module, the tear gas trigger module, and the microcontroller respectively.

[0007] The control host further includes a manual trigger button, and the manual trigger button is electrically connected to the input end of the microcontroller.

[0008] The control host further includes a voice alarm module, and the input end of the voice alarm module is electrically connected to the output end of the microcontroller.

[0009] The power supply module includes a main power supply circuit, a backup power supply circuit and a backup battery charging circuit.

[0010] Each of the first tear gas emitter, the second tear gas emitter and the third tear gas emitter includes a tear gas cartridge, a spring bracket and a mounting cylinder. The tear gas cartridge is arranged in the mounting cylinder through the spring bracket. A wire passing hole is opened at the top end of the mounting cylinder, and a smoke discharging hole is opened at the bottom end of the mounting cylinder. The spring bracket is a hollow cylindrical shape. The inner diameter of the spring bracket matches the diameter of the tear gas cartridge. The outer diameter of the upper part of the spring bracket matches the inner diameter of the mounting cylinder. The outer diameter of the lower part of the spring bracket is smaller than the inner diameter of the mounting cylinder. An electric ignition head is arranged at the top end of the tear gas cartridge. The tear gas cartridge is filled with a tear gas agent. Sealed smoke discharging holes are respectively opened at the top end and the bottom end of the tear gas cartridge. A smoke discharging cavity extends upward from the outer wall of the top end of the tear gas cartridge.

[0011] The mounting cylinder includes a cylinder body, an end cover and a base. A wire passing hole is opened on the end cover, and a filter screen is arranged on the base.

[0012] A plurality of smoke discharging holes are opened around the electric ignition head at the top end of the tear gas cartridge.

[0013] An installation seat is arranged on the end cover, and the installation seat is connected to the end cover through a universal adjusting bracket.

[0014] A buffer baffle is arranged on the base, and the buffer baffle is located at the center of the filter screen.

[0015] The end cover and the base are respectively threadedly connected to the upper end and the lower end of the cylinder body.

[0016] The present invention respectively uses the cash replenishment area detection tear gas component, the customer area detection tear gas component and the business hall detection tear gas component to conduct zonal management on the cash replenishment area, the customer area and the business hall of the bank. When a robbery or theft event occurs in any area, not only can the control host receive an alarm signal to automatically detonate the tear gas device, but also the monitoring terminal can remotely detonate the tear gas device according to the monitoring picture, so as to achieve the purpose of preventing and aborting illegal acts, and fully improve the effectiveness and reliability of the tear gas security system.

[0017] Furthermore, the tear gas emitter of the present invention uses a spring bracket to fix the tear gas column in the installation cylinder, which can prevent the tear gas column from colliding with the installation cylinder. By opening smoke holes at the upper and lower ends of the tear gas column respectively, when the tear gas column is detonated, the tear gas smoke released from the lower smoke hole is directly discharged through the smoke hole at the bottom of the installation cylinder, and the tear gas smoke released from the upper smoke hole enters the installation cylinder through the gap of the spring bracket and then is discharged through the smoke hole at the bottom of the installation cylinder, effectively increasing the smoke emission amount of the tear gas column in a short time and being able to promptly stop the criminal acts of lawbreakers.

[0018] Furthermore, the present invention sets a buffer baffle on the base of the installation cylinder, so that the tear gas smoke diffuses appropriately when encountering resistance after being released, which is beneficial to the tear gas smoke playing a role in real time. At the same time, the buffer baffle can effectively isolate the heat generated when the tear gas column emits smoke.

[0019] Furthermore, the installation cylinder of the present invention is connected to the mounting base through a universal adjustment bracket, so that after the installation cylinder is fixed through the mounting base, the orientation of the tear gas column when emitting smoke can be adjusted arbitrarily, effectively improving the flexibility of the use of the tear gas column.

[0026] As Figure 1 shown, an intelligent tear gas security system of the present invention includes a cash loading area detection and tear gas component, a customer area detection and tear gas component, a business hall detection and tear gas component, a control host and a monitoring terminal. The cash loading area detection and tear gas component includes a door magnetic switch, an infrared pair sensor, a first camera and a first tear gas emitter. The customer area detection and tear gas component includes a vibration sensor, a sound sensor, a second camera and a second tear gas emitter. The business hall detection and tear gas component includes a third camera and a third tear gas emitter. The control host includes a detection signal receiving module, a tear gas triggering module, a network communication module, a power supply module and a microcontroller.

[0027] The output ends of the described door magnetic switch, infrared pair sensor, vibration sensor, and sound sensor are respectively electrically connected to the input end of the detection signal receiving module. The output end of the detection signal receiving module is electrically connected to the input end of the microcontroller. The input ends of the first tear gas emitter, second tear gas emitter, and third tear gas emitter are respectively electrically connected to the output end of the tear gas trigger module. The input end of the tear gas trigger module is electrically connected to the output end of the microcontroller. The first camera, second camera, and third camera are respectively connected to the monitoring terminal through the RS485 bus. The microcontroller is connected to the monitoring terminal through the network communication module. The power supply module supplies power to the detection signal receiving module, network communication module, tear gas trigger module, and microcontroller respectively.

[0028] The present invention uses a cash replenishment room detection tear gas component to protect the bank cash replenishment room. That is, a door magnetic switch is installed on the door of the cash replenishment room, an infrared pair sensor is installed on the side of the cash replenishment bin, a first camera is installed on the top of the cash replenishment room, and a first tear gas emitter is installed inside the cash replenishment room. In the deployment state, if someone opens the door and breaks in illegally, the door magnetic switch generates an alarm signal and transmits the alarm signal to the control host through the detection signal receiving module. If someone approaches the cash replenishment bin of the ATM illegally, the infrared pair sensor generates an alarm signal and transmits the alarm signal to the control host through the detection signal receiving module. The control host synchronously transmits the received alarm signal to the monitoring terminal through the network communication module. On the one hand, if the door magnetic switch and the infrared pair sensor generate alarm signals simultaneously or successively, the control host automatically detonates the first tear gas emitter installed in the cash replenishment room through the tear gas trigger module. On the other hand, after the monitoring terminal receives the alarm signal generated by the door magnetic switch and / or the infrared pair sensor, the staff can view the on-site monitoring video through the first camera. If it is confirmed that a theft event is occurring and the control host has not detonated the first tear gas emitter, an instruction can be remotely sent through the network communication module to make the control host detonate the first tear gas emitter in time to prevent criminals from stealing the cash in the cash replenishment bin.

[0029] The present invention uses a tear - gas emission component for customer area detection to protect the customer area of a self - service bank. That is, a vibration sensor and a sound sensor are installed on an ATM machine, a second camera is installed at the top of the customer area, and a second tear - gas emitter is installed inside the customer area. If there are situations such as damaging the ATM machine or robbing customers in the customer area, the vibration sensor and / or the sound sensor generate an alarm signal, and the alarm signal is transmitted to the control host through the detection signal receiving module. The control host synchronously transmits the received alarm signal to the monitoring terminal through the network communication module. The staff judge the on - site situation by viewing the monitoring screen of the second camera. If the situation is critical and it is necessary to immediately detonate the tear gas, the staff remotely send an instruction through the network communication module to make the control host detonate the second tear - gas emitter in time, so as to achieve the purpose of preventing and aborting illegal acts.

[0030] The present invention uses a tear - gas emission component for business hall detection to protect the bank business hall. That is, a third camera and a third tear - gas emitter are installed above the business hall. If the staff of the monitoring terminal discovers an emergency in the business hall through the monitoring screen, they remotely send an instruction through the network communication module to make the control host detonate the third tear - gas emitter in time and release the tear gas.

[0031] The control host further includes a manual trigger button, and the manual trigger button is electrically connected to the input end of the microcontroller. In an emergency, the bank teller can detonate the third tear - gas emitter through the manual trigger button. If the business teller is controlled and unable to act, the monitoring terminal can remotely activate the third tear - gas emitter.

[0032] The control host further includes a voice alarm module, and the input end of the voice alarm module is electrically connected to the output end of the microcontroller. When the control host receives one or more alarm signals, it gives a voice warning to the lawbreakers through the voice alarm module and at the same time reminds the on - site personnel to pay attention to safety.

[0033] The power supply module includes a main power supply circuit, a backup power supply circuit and a backup battery charging circuit. In a power - off state, the backup power supply circuit can ensure the normal operation of the control host and improve the reliability of the system.

[0034] As Figure 2 and Figure 3 shown, the first tear - gas emitter, the second tear - gas emitter and the third tear - gas emitter have the same structure, and each includes a tear - gas charge 1, a spring support 3 and an installation cylinder 2. The tear - gas charge 1 is arranged in the installation cylinder 2 through the spring support 3. A wire - passing hole is opened at the top end of the installation cylinder 2, and a smoke - discharging hole is opened at the bottom end of the installation cylinder 2. The installation cylinder 2 is installed in a place where a security system is set up. When the tear - gas charge 1 is detonated, tear - gas smoke is discharged outward through the installation cylinder 2.

[0035] The described spring bracket 3 is in the shape of a hollow cylinder. The inner diameter of the spring bracket 3 matches the diameter of the tear gas column 1. The tear gas column 1 can be placed inside the spring bracket 3 without colliding with the inner wall of the installation cylinder 2. The outer diameter of the upper part of the spring bracket 3 matches the inner diameter of the installation cylinder 2. When the spring bracket 3 is placed inside the installation cylinder 2, the spring bracket 3 can be located at the upper part of the installation cylinder 2 without falling off. The outer diameter of the lower part of the spring bracket 3 is smaller than the inner diameter of the installation cylinder 2. When the tear gas column 1 is pressed down, the spring bracket 3 can be longitudinally extended and move downward under the force.

[0036] As Figure 4 shown, an electric ignition head is provided at the top end of the described tear gas column 1. The tear gas column 1 is filled with tear gas agent. Sealed smoke holes 4 are respectively opened at the top and bottom ends of the tear gas column 1. The outer wall of the top end of the tear gas column 1 extends upward to form a smoke release cavity 9. When the control host controls the electric ignition head to ignite through the lead wire, the tear gas smoke generated by the tear gas column 1 is released through the smoke holes 4. Among them, the tear gas smoke released through the smoke hole 4 at the bottom end of the tear gas column 1 directly enters the installation cylinder 2. A plurality of smoke holes 4 are opened around the electric ignition head at the top end of the tear gas column 1. The tear gas smoke released through the smoke holes 4 at the top end of the tear gas column 1 first enters the smoke release cavity 9 and forms a relatively large air pressure inside the smoke release cavity 9. The tear gas column 1 is pressed downward by the force and moves downward along with the spring bracket 3. Then, the tear gas smoke inside the smoke release cavity 9 enters the installation cylinder 2 through the gaps of the spring bracket 3.

[0037] The described installation cylinder 2 includes a cylinder body 21, an end cover 22 and a base 23. The end cover 22 and the base 23 are respectively threadedly connected to the upper and lower ends of the cylinder body 21. A wire passing hole is opened on the end cover 22, and a sealing ring is arranged inside the wire passing hole. The signal wire of the tear gas column 1 is led out of the installation cylinder 2 through the wire passing hole. An installation seat 6 is also arranged on the end cover 22. The installation seat 6 is connected to the end cover 22 through a universal adjustment bracket 5. As Figure 5 shown, a fixing frame 10 is provided at the top end of the installation seat 6. The fixing frame 10 is in an inverted U shape. Installation holes are respectively opened on the side walls of the installation seat 6 and the fixing frame 10. The side wall of the fixing frame 10 is bolted to the side wall of the installation seat 6. After the installation seat 6 is fixed at a certain place through the fixing frame 10, the rotation angle of the universal adjustment bracket 5 can be adjusted to arbitrarily change the orientation of the installation cylinder 2.

[0038] As Figure 6As shown, the bottom surface of the base 23 is provided with a filter 7, which is used to filter the residue produced when the tear gas column 1 emits smoke. The tear gas smoke entering the mounting tube 2 is discharged outward through the filter 7 of the base 23, achieving the purpose of promptly stopping illegal activities. The base 23 of the mounting tube 2 is also provided with a buffer baffle 8, which is located at the center of the filter 7. When the tear gas smoke is discharged outward through the filter 7, it partially impacts the buffer baffle 8, which diffuses the tear gas smoke and helps it spread quickly to a specific area. At the same time, the buffer baffle 8 can isolate the heat generated by the tear gas column 1 when it emits smoke.

[0039] The working principle of the present invention is as follows: when the door magnetic switch and infrared radiation sensor in the banknote adding room generate an alarm signal, the control host automatically activates the first tear gas emitter installed in the banknote adding room, or the staff of the monitoring terminal remotely activates the first tear gas emitter after judging through the monitoring screen; when the vibration sensor and sound sensor in the customer area generate an alarm signal, the control host uploads the alarm signal to the monitoring terminal, and the staff of the monitoring terminal manually judges illegal behavior based on the monitoring screen and remotely activates the second tear gas emitter at the appropriate time; when an emergency occurs in the business hall, the bank teller manually detonates the third tear gas emitter, or the staff of the monitoring terminal remotely activates the third tear gas emitter at the appropriate time.

[0040] Furthermore, when the tear gas column 1 in the tear gas launcher is triggered, a large amount of tear gas smoke is generated. Part of the tear gas smoke is released through the smoke hole 4 at the bottom end of the tear gas column 1, directly enters the installation tube 2, and is discharged through the filter 7 at the bottom end of the installation tube 2; part of the tear gas smoke is released through the smoke hole 4 at the top end of the tear gas column 1, enters the smoke discharge chamber 9, and generates a large air pressure in the smoke discharge chamber 9. The tear gas column 1 moves downward under the action of pressure and drives the spring bracket 3 downward. The upper end of the smoke discharge chamber 9 is separated from the end cover 22 of the installation tube 2, and the tear gas smoke enters the installation tube 2 through the gap of the spring bracket 3, and is finally discharged through the filter 7 at the bottom end of the installation tube 2.
