Description

Technical Field

[0001] The utility model relates to the field of building anti-theft, and in particular to an intelligent building anti-theft system. Background Art

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the demand for security protection in homes and commercial buildings is increasing. Traditional physical locks and simple alarm systems can no longer meet the high security requirements of modern society.

[0003] Existing building security systems typically use infrared sensing technology to detect intrusions. These systems are equipped with infrared sensors that, when an object passes through, trigger and activate connected alarm systems or lighting devices. In addition, some systems may also include video surveillance equipment to record intrusions.

[0004] Although existing building anti-theft systems can provide anti-theft functions to a certain extent, they still have some obvious limitations in practical applications. For example, although a single infrared sensor can detect the presence of moving objects, it is difficult to distinguish between illegal intruders and normal visitors, which may lead to frequent false alarms and low overall anti-theft efficiency of the system. Utility Model Content

[0005] The utility model provides an intelligent building anti-theft system, which is used for more accurately judging intrusion behavior and improving the anti-theft effect.

[0006] To achieve the above-mentioned purpose, the technical solution of the present utility model provides an intelligent building anti-theft system, which includes multiple infrared sensors, a first speaker module, a camera module, a pressure detection module, and multiple lighting modules;

[0007] The plurality of infrared sensors are connected to the plurality of light modules in a one-to-one correspondence, and are connected to the first speaker module and the camera module, and are used to send the detected infrared digital signals to the camera module, the speaker module and the corresponding light module;

[0008] The light module is used to turn on the light when receiving the infrared digital signal sent by the infrared sensor;

[0009] The pressure detection module is installed on the anti-theft door and connected to the first speaker module, and is used to send the detected pressure signal to the first speaker module;

[0010] The first speaker module is installed on the anti-theft door and is connected to the plurality of infrared sensors and the pressure detection module, and is used to turn on the speaker when receiving the pressure signal sent by the pressure detection module and the infrared digital signal sent by the infrared sensor;

[0011] The camera module is installed on the anti-theft door and is connected to multiple infrared sensors. It is used to turn on the camera and start recording when it receives an infrared digital signal.

[0012] Using the above embodiment, the overall framework of the intelligent building security system primarily includes an infrared sensor, a lighting module, a pressure detection module, a first speaker module, and a camera module. When the infrared sensor detects an intrusion signal, it triggers the corresponding light to illuminate, the first speaker to sound, and the camera to begin recording. This allows for more accurate identification of intrusions, while also providing a deterrent effect through the lighting and sounding, and the camera to record evidence. The entire system is highly automated, requiring no human intervention and providing 24-hour continuous alert, enhancing the security effect.

[0013] In some embodiments, the intelligent building anti-theft system further comprises: a pressure comparator;

[0014] The pressure comparator is connected to the pressure detection module and the first speaker module, and is used to receive the pressure signal detected by the pressure detection module, and send a second control signal to the first speaker module when the pressure signal is greater than a preset threshold.

[0015] Using the above embodiment, the pressure comparator can detect pressure changes on the door. When the pressure exceeds the weight of the door itself, it indicates that someone may be trying to open or destroy the door lock. The pressure comparator can also transmit this signal to the first speaker to trigger an alarm. Even if the infrared sensor fails, the anti-theft effect can be achieved, and the system's protection range is more comprehensive.

[0016] In some embodiments, the intelligent building anti-theft system further comprises: a first control chip;

[0017] The first control chip is used to connect with the infrared sensor, the lighting module and the camera module, and is used to receive infrared digital signals sent by the plurality of infrared sensors, convert the infrared digital signals into a first control signal, and send the first control signal to the lighting module and the camera module;

[0018] The lighting module is used to turn on the light when receiving the first control signal;

[0019] The camera module is configured to start recording upon receiving a first control signal.

[0020] By adopting the above embodiment, a more accurate and reliable control logic is realized, and each signal is digitally processed, making the entire system more unified and efficient.

[0021] In some embodiments, the intelligent building anti-theft system further comprises: a second speaker module;

[0022] The second speaker module is installed in the building and connected to the pressure comparator, and is used to play a preset audio when receiving a second control signal sent by the pressure comparator.

[0023] In the above embodiment, a second speaker module is installed inside the building. When the pressure comparator detects signs of intrusion, a preset alarm audio signal is played through the second speaker module. This provides a greater warning effect. Because the first speaker module is installed outside the door, the sound has a limited range. Adding a second speaker allows the alarm to be heard throughout the entire building interior, deterring intruders while also reminding residents to be safe. The audio content can also be flexibly configured, from a warning tone to a noisy ambient sound that can deceive thieves into thinking someone is inside.

[0024] In some embodiments, the intelligent building anti-theft system further comprises: a timer;

[0025] The timer is connected to the plurality of infrared sensors and is used to send a third control instruction to the plurality of infrared sensors when the current time reaches a preset time range;

[0026] The plurality of infrared sensors are used to turn off the infrared sensors when receiving a third control instruction.

[0027] In the above embodiment, the intelligent building security system uses a timer to disable the infrared sensor during specific time periods. This prevents frequent false alarms from the infrared sensor during daytime hours when many people enter and exit. By only turning the sensor on at night, when security is key, the system maintains its security effectiveness while minimizing the possibility of false alarms.

[0028] In some embodiments, in the intelligent building anti-theft system, a plurality of infrared sensors are arranged at preset intervals within a preset distance from the anti-theft door outside the building.

[0029] By adopting the above embodiment, in the intelligent building anti-theft system, infrared sensors need to be set within a certain range of the door and at equal intervals to form multiple monitoring areas. When an intruder opens the door and enters, each sensor will be triggered in turn. The system can clearly determine the direction of the intrusion. The monitoring range of the entire area is wider and more accurate, thereby improving the security capability of the system.

[0030] In some embodiments, in the intelligent building anti-theft system, a plurality of light modules are arranged above the plurality of infrared sensors at a preset interval, corresponding one-to-one to the plurality of infrared sensors.

[0031] In the above embodiment, the placement of the light modules is limited. They need to be placed above the infrared sensors in a one-to-one correspondence. When the infrared sensors detect an intrusion, the corresponding lights will illuminate. This can accurately locate the intruder's location and also serve as a warning. Compared with only placing lights at the door, this point-to-point arrangement can illuminate a wider area, making it easier to detect the specific actions of the intruder.

[0032] In some embodiments, the intelligent building anti-theft system further comprises: a power controller;

[0033] The power controller is connected to the second speaker module and is used to send a power control instruction when the second speaker module plays audio, the power control instruction being used to control the power of the second speaker module to increase by a preset power threshold within a preset audio playback time;

[0034] The second speaker module is configured to increase power by a preset power threshold within a preset audio playback time when receiving a power control instruction.

[0035] By adopting the above embodiment, the power controller can control the volume to gradually increase by a certain amplitude when the second speaker module plays the alarm audio. This gradually increasing volume is more likely to disturb the intruder and is more conducive to forming an echo propagation effect inside the entire building, thereby enhancing the warning effect of the alarm audio.

[0036] In some embodiments, the intelligent building anti-theft system further comprises: a switch detector;

[0037] The switch detector is installed on the anti-theft door to detect whether the anti-theft door is opened.

[0038] By adopting the above embodiment, it is possible to monitor in real time whether the door lock is illegally opened. Even if an intruder avoids the detection of the infrared sensor through special means, he cannot evade the detection of the door lock, thereby further improving the security and protection strength of the system.

[0039] In some embodiments, the intelligent building anti-theft system further comprises: a client;

[0040] The switch detector is connected to the client and is used to send a fourth instruction message to the client when the anti-theft door is opened;

[0041] The client is installed in a security booth outside the building and is used to send out an alarm message when receiving the fourth control instruction.

[0042] With the above embodiment, when the door lock switch detector detects that the door is opened, it will send a signal to the client, and the client will sound an alarm, further expanding the monitoring range of the anti-theft system. Not only is there an alarm device inside the door, but there is also an additional line of defense outside the door. Security personnel in the monitoring booth can be notified of the intrusion in the first time and quickly take countermeasures, such as notifying the police.

[0043] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0044] 1. Since the utility model is provided with an infrared sensor, a lighting module, a pressure detection module, a first speaker module and a camera module, when the infrared sensor detects an intrusion signal, it will trigger the corresponding light to light up, the first speaker to sound, and notify the camera to start recording, which can more accurately judge the intrusion behavior. At the same time, the lighting and sounding will produce a deterrent effect, and the camera can record evidence. The entire system has a high degree of automation, does not require human participation, can maintain continuous vigilance 24 hours a day, and improves the anti-theft effect.

[0045] 2. Because the present invention includes a second speaker module installed inside the building, when the pressure comparator detects signs of intrusion, a preset alarm audio signal can be played through the second speaker module. This provides a greater warning effect. Because the first speaker module is installed outside the door, the sound transmission range is limited. Adding a second speaker allows the alarm to be transmitted throughout the entire building interior, deterring intruders while also reminding residents to pay attention to safety. The audio content can also be flexibly configured, from a warning tone to a noisy ambient sound that can deceive thieves into thinking someone is inside.

[0046] 3. Since the utility model is provided with a power controller, the volume can be controlled to gradually increase by a certain amplitude when the second speaker module plays the alarm audio. This gradually increasing volume is more likely to disturb the intruder and is more conducive to forming an echo propagation effect inside the entire building, thereby enhancing the warning effect of the alarm audio and causing psychological fear in the intruder.

[0054] The utility model provides an intelligent building anti-theft system, such as Figure 1 FIG. 1 is a schematic diagram showing the device connection of an embodiment of the present utility model.

[0055] For ease of understanding, the following describes the intelligent building anti-theft system provided by this embodiment in combination with the above embodiments. Figure 1 , Figure 1 It is a schematic diagram of an embodiment of the present utility model.

[0056] The utility model provides an intelligent building anti-theft system, such as Figure 1As shown, it is a schematic diagram of an embodiment of the present utility model. The intelligent building anti-theft system includes multiple infrared sensors 1, a first speaker module 4, a camera module 5, a pressure detection module 3, and multiple light modules 2; multiple infrared sensors 1 are connected to multiple light modules 2 in a one-to-one correspondence, and are connected to the first speaker module 4 and the camera module 5, for sending the detected infrared digital signal to the camera module 5, the first speaker module 4 and the corresponding light module 2, the light module 2 is used to turn on the light when receiving the infrared digital signal sent by the infrared sensor 1, the pressure detection module 3 is installed on the anti-theft door, connected to the first speaker module 4, for sending the detected pressure signal to the first speaker module 4, the first speaker module 4 is installed on the anti-theft door, connected to the multiple infrared sensors 1 and the pressure detection module 3, for turning on the speaker when receiving the pressure signal sent by the pressure detection module 3 and the infrared digital signal sent by the infrared sensor 1, the camera module 5 is installed on the anti-theft door, connected to the multiple infrared sensors 1, for turning on the camera to start recording when receiving the infrared digital signal.

[0057] Specifically, the infrared sensor in this intelligent building security system can be a PIR-type infrared detector operating in the 850nm wavelength band with a detection range of up to 10 meters. This type of detector is sensitive to ambient temperature fluctuations and can effectively detect human motion. The sensor outputs a standard digital signal, such as an 8-bit or 16-bit code. This digital signal, which is threshold-determined data, can be directly input into a microcontroller. The corresponding lighting module can utilize a white LED light assembly that illuminates upon receiving the digital signal from the infrared sensor, emitting a strong light stimulus. This light assembly can utilize an adjustable LED light source and a simple optical system design. To ensure effectiveness, multiple light assemblies can be positioned within a 3-meter radius above the doorway. The first speaker module can utilize a speaker with an output power of 20-40W. Upon receiving a signal, it plays a preset alarm tone, such as an alarm or warning message, at a volume of ≥80dB, to provide a psychological deterrent to intruders. Its installation location is also optimized within 3 meters above the doorway. The camera module can utilize an industrial-grade CCD camera with a sensor resolution of 8 megapixels or higher. Upon receiving a signal, it automatically captures and records the doorway area to capture an image of the intruder. To ensure the effect, at least 2 cameras can be set up to cross-cover the door area.

[0058] For ease of understanding, the following further describes the intelligent building anti-theft system provided by this embodiment in combination with the above embodiments. Figure 2 , Figure 2 It is another schematic diagram of an embodiment of the present utility model.

[0059] In some embodiments, the intelligent building anti-theft system further includes: a pressure comparator, the pressure comparator 6 is connected to the pressure detection module 3 and the first speaker module 4, and is used to receive the pressure signal detected by the pressure detection module 3, and send a second control signal to the first speaker module 4 when the pressure signal is greater than a preset threshold.

[0060] Specifically, the pressure detection module can use a piezoresistive pressure sensor to convert the detected pressure into a voltage signal output. Its measurement range can be set to 0-50N, corresponding to 2-3 times the weight of the door leaf itself.

[0061] The pressure comparator uses an operational amplifier circuit to compare the detected voltage with a set threshold. For example, if the detected value exceeds 20N, a high-level control signal is output, triggering an alarm on the first speaker. The operational amplifier's fast response speed effectively detects instantaneous pressure changes.

[0062] In some embodiments, the intelligent building anti-theft system also includes: a first control chip 7, the first control chip 7 is used to connect with the infrared sensor 1, the lighting module 2 and the camera module 5, and is used to receive infrared digital signals sent by multiple infrared sensors 1, convert the infrared digital signals into a first control signal, and send the first control signal to the lighting module 2 and the camera module 5. The light module is used to turn on the light when it receives the first control signal, and the camera module is used to start recording when it receives the first control signal.

[0063] Specifically, the first control chip can select a 32-bit ARM microcontroller with integrated peripherals such as A / D conversion module, timer, serial communication, etc. It can perform timed sampling and AD conversion on the analog signal of the infrared module to realize digital signal analysis, and at the same time send timing pulses and interrupts to other peripherals to control the operation of infrared sensors, lighting modules, and cameras. The microcontroller adopts a deep sleep mode that can greatly reduce power consumption, and can work stably and reliably for a long time. It can also realize more new functions by upgrading its control logic online.

[0064] In some embodiments, the intelligent building anti-theft system further includes a second speaker module 8 , which is installed in the building and connected to the pressure comparator 6 , and is used to play a preset audio when receiving a second control signal sent by the pressure comparator 6 .

[0065] Specifically, the second speaker module can be an indoor intercom speaker with a power of over 100W, installed in key locations within the building, such as lobbies and stairwells. Upon receiving a control signal, it plays a preset human voice alarm at a volume of up to 90-100 decibels. The alarm content can be customized, ranging from a warning voice reminder to a terrifying sound like shouting or screaming. Furthermore, the positioning of the second speaker can achieve an asynchronous stereo effect, creating a superposition, diffusion, and reflection of sound waves throughout the building, enhancing the warning effect.

[0066] In some embodiments, the intelligent building anti-theft system further includes a timer 9, which is connected to the plurality of infrared sensors 1 and is configured to send a third control instruction to the plurality of infrared sensors 1 when the current time reaches a preset time range;

[0067] The plurality of infrared sensors 1 are configured to turn off the infrared sensors 1 upon receiving a third control instruction.

[0068] Specifically, the timer module can be implemented by a timer / counter hardware circuit built into a microcontroller. During the period of 18:00-07:00 every day, it automatically outputs a low level and turns off the power supply of the infrared sensor.

[0069] This prevents false alarms from being triggered by daytime traffic. The system is activated only at night, when key precautions are needed. This saves energy, reduces false alarms, and improves reliability. Operating hours can also be adjusted based on actual needs.

[0070] In some embodiments, in the intelligent building anti-theft system, a plurality of infrared sensors 1 are arranged at a preset interval within a preset distance from the anti-theft door outside the building.

[0071] Specifically, infrared sensors are placed every two meters on both sides of the door, forming multiple monitoring zones. Covering the entire 10-meter radius, this layout ensures seamless monitoring, preventing intruders from circumventing detection by identifying blind spots. Furthermore, the sequential triggering of different zones can determine the direction of intrusion, allowing for proactive countermeasures and enhanced system protection.

[0072] In some embodiments, in the intelligent building anti-theft system, a plurality of light modules 2 are arranged above a plurality of infrared sensors 1 at a preset interval, corresponding one-to-one to the plurality of infrared sensors 1 .

[0073] Specifically, the lighting module can be an IP65-rated LED floodlight, mounted approximately 3 meters above the infrared sensor, one-to-one with the infrared sensor. When the corresponding sensor detects an intrusion, the lighting module illuminates, generating a brightness of 2000 lumens. This can accurately locate the intrusion site and create a bright lighting effect, making it impossible for the intruder to hide. Considering that the door range is approximately 10 meters, if there are about five sensors, five LED lighting modules of the same specifications will be required, and a tower or other support structure will be used to achieve precise alignment with each sensor.

[0074] In some embodiments, the intelligent building anti-theft system also includes a power controller 10, which is connected to the second speaker module 8 and is used to send a power control instruction when the second speaker module 8 plays audio. The power control instruction is used to control the power of the second speaker module 8 to increase by a preset power threshold within the playback time of the preset audio. The second speaker module 8 is used to increase the power by a preset power threshold within the playback time of the preset audio when receiving the power control instruction.

[0075] Specifically, the power controller module can be composed of a digital potentiometer chip and an operational amplifier. It can adjust the gain of the audio amplifier circuit in real time. After the alarm is turned on, the module will increase the amplification factor by 5dB every 10 seconds, so that the alarm volume output by the second speaker increases in a step-by-step manner and reaches the maximum value within 60 seconds, achieving a gradually increasing deterrent effect. The control signal of the power controller can be generated by the same microcontroller, or through a simple timing reference circuit design to reduce system complexity.

[0076] In some embodiments, the intelligent building anti-theft system further includes a switch detector 11 , which is installed on the anti-theft door and is used to detect whether the anti-theft door is opened.

[0077] Specifically, the switch detector can adopt a door magnetic switch sensor, which is installed at the edge of the door leaf to detect whether the anti-theft door is opened.

[0078] The built-in door magnetic switch maintains a normally closed contact when the door is closed. When the door is opened, the change in magnetic field causes the internal contact to disconnect and output a detection signal to prevent circumvention of monitoring by other anti-theft modules.

[0079] Door magnetic sensors are simple in structure, highly reliable, and low in cost, making them an effective choice for door lock monitoring. The digital signals they output are also easily processed by the backend.

[0080] In some embodiments, the intelligent building anti-theft system also includes a client 12, and the switch detector 11 is connected to the client 12, and is used to send a fourth instruction information to the client 12 when the anti-theft door is opened. The client 12 is installed in a security booth outside the building, and is used to send an alarm message when receiving the fourth control instruction.

[0081] Specifically, the client can be an embedded industrial computer or a dedicated monitoring computer installed in the security booth. It includes an alarm interface for connecting to a door lock switch detector, which triggers an alarm when a door opening signal is received.

[0082] The alarm method can be a buzzer alarm, voice alarm, etc. The alarm volume should be set at 75-90 decibels to ensure that security personnel can hear it clearly.

[0083] The client can also integrate other functions, such as surveillance video display of the door area, intercom function, etc. It can also be connected to the main system of the security room via a network cable to achieve remote monitoring and control.

[0084] Security booths can be designed to be windproof and rainproof, and use tempered glass to prevent vandalism. The location of the booth should also facilitate monitoring of the doorway.

[0085] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
