Detailed Implementation

[0020] The present invention will be further explained below with reference to the accompanying drawings.

[0021] See attached document Figure 1 -Appendix Figure 5 This embodiment includes a gimbal 110, a laser security system, and a power module 160. The laser security system is installed on the gimbal 110, and the power module 160 is connected to both the gimbal 110 and the laser security system to provide power to both. The pan-tilt unit 110 can rotate around its own axis, enabling flexible rotation in both horizontal and vertical directions to ensure comprehensive coverage of the monitored area. Internally, it is equipped with a precision motor drive system 111 and an angle sensor 112. The laser security system includes a monitoring module 120, a control module 150, an audible and visual warning module 130, and a laser emission module 140. All of these modules are connected to the control module 150. Simultaneously, the motor drive system 111 and angle sensor 112 of the pan-tilt unit 110 are also connected to the control module 150. The motor drive system 111 is responsible for precisely adjusting the angle of the pan-tilt unit 110 according to control commands, while the angle sensor 112 provides real-time feedback of the pan-tilt unit 110's current position to the control module 150, ensuring accurate positioning and stable operation.

[0022] The gimbal 110 is made of high-strength aluminum alloy, ensuring a stable structure and moderate weight for easy installation and relocation. Its motor drive system 111 uses a high-precision brushless motor, combined with a precision reducer and encoder, to achieve high precision and stability in angle adjustment. The angle sensor 112 uses a combination of a high-precision gyroscope and accelerometer to ensure real-time and accurate feedback of the gimbal 110's attitude information.

[0023] The control module 150 is the core control unit of the system. Designed based on a microcontroller (such as an ARM-based microcontroller), it stores preset control programs and logic rules. By receiving image data from the monitoring module and pan-tilt-zoom (PTZ) angle information, it performs rapid judgment and decision-making according to the program. Its connection with other modules uses high-speed and reliable communication interfaces, such as Ethernet, USB, or CAN bus, ensuring real-time and accurate data transmission. The control module 150 receives image analysis results and PTZ angle information from the monitoring module 120. Based on preset logic and programs, it makes judgments and decisions. When an intrusion is detected, it sends corresponding control commands to the audible and visual alarm module 130 and the laser emission module 140 based on the intruder's distance and behavioral characteristics. Simultaneously, it controls the PTZ 110 to rotate to adjust the monitoring and response direction.

[0024] The monitoring module 120 includes a camera 121 and an image processor 122. The camera 121 is a high-definition camera responsible for real-time acquisition of image information within the monitored area. It features high resolution and wide dynamic range, enabling clear capture of personnel images under various lighting conditions. The image processor 122 employs a high-performance digital signal processor (DSP) or field-programmable gate array (FPGA) chip, running advanced target detection and recognition algorithms, such as deep learning-based convolutional neural network (CNN) algorithms. After training with a large number of samples, it can quickly and accurately identify intruders. The input of the image processor 122 is connected to the camera 121, and its output is connected to the control module 150, enabling rapid analysis and processing of the acquired images. For example, it uses advanced image processing algorithms for target detection and recognition to determine the presence of intruders and their location, posture, and other information, transmitting the processing results to the control module 150 for rapid response.

[0025] The audible and visual warning module 130 includes a speaker 131 and a high-intensity flashlight 132, both of which are connected to the control module 150. Upon receiving instructions from the control module 150, both modules execute corresponding warning actions. When the control module triggers an audible warning, the speaker 131 emits a high-decibel alarm sound; its volume and timbre can be set and adjusted according to actual needs to effectively deter intruders. The high-intensity flashlight 132 emits a bright light instantaneously when a dazzling warning is needed; its brightness and flashing frequency can also be adjusted to interfere with the intruder's vision.

[0026] The laser emitting module 140 includes a laser 141, an aiming device 142, and a power adjustment unit 143. The output terminal of the power adjustment unit 143 is connected to the laser 141, and the input terminal of the power adjustment unit 143 is connected to the control module 150. The aiming device 142 is mounted on the laser 141, and its input terminal is connected to the control module 150, while its output terminal is connected to the laser 141. The laser 141 is directly connected to the control module 150, and the aiming device 142 is an infrared aiming scope. The laser 141 is a semiconductor laser with a suitable wavelength (such as 980nm or 1064nm) and power range (such as 10W-100W). The laser 141 emits laser light under the command of the control module 150, and its wavelength and power can be selected and adjusted according to actual needs to achieve effective laser temperature control reminders. The aiming device 142 activates before emitting the laser, precisely targeting specific parts of the intruder's body with a red laser beam to warn them. Internally, it employs a high-precision optical aiming system and an automatic tracking algorithm to ensure stable targeting even during the movement of the gimbal 110. The power adjustment unit 143 dynamically adjusts the laser 141's output power using an electronic voltage regulation circuit or pulse width modulation (PWM) technology based on the control module command 150 and target distance information, ensuring an effective deterrent effect through a noticeable burning sensation. To ensure effective heat dissipation of the laser 141, its cooling system employs either an air-cooled system or a phase-change cooling system. In this embodiment, a phase-change cooling system is used, which, while ensuring heat dissipation, reduces the size of the laser 141 to some extent, facilitating integration.

[0027] The power module 160 provides stable power support for the entire system, including a rechargeable battery pack and a power management circuit. The rechargeable battery pack is a lithium battery pack. The rechargeable battery pack has sufficient capacity to ensure that the system can still operate normally without an external power source for extended periods. The power management circuit is responsible for managing the charging and discharging of the battery, stabilizing the voltage, and distributing power, ensuring a stable and reliable power supply to each module and preventing voltage fluctuations from affecting the system.

[0028] System operating principle and process: After system startup, the camera 121 on the monitoring module 120 continuously collects image information of the monitored area and transmits it to the image processor 122. The image processor 122 analyzes the images in real time and transmits the analysis data to the control module 150. Once an unauthorized person is identified entering the monitored area, the distance between them and the protected target is immediately calculated. For example, when the unauthorized person is more than a certain distance (e.g., 10 meters) from the protected target, the system is in a monitoring and early warning state. The monitoring module 120 continuously tracks the person's movement but does not trigger an alarm. When the unauthorized person is between 5 and 10 meters from the protected target, the control module 150 activates the audible and visual alarm module 130. The speaker 131 emits an alarm sound, and the high-intensity light 132 can flash or remain constantly lit as needed to initially deter and warn the intruder. At the same time, the pan-tilt unit 110 can automatically adjust its angle according to the direction of the person's movement to ensure that the intruder is always monitored. If the intruder continues to approach after the audible and visual alarm, and the distance to the protected target is less than 5 meters but more than 3 meters, the control module 150 will activate the alarm. Module 150 controls laser emission module 140 to activate aiming device 142, emitting a red laser beam to target the intruder's body parts as a warning. At this time, laser 141 temporarily refrains from emitting high-power laser, providing further warning to the intruder. When the intruder is less than 3 meters from the protected target and still has not stopped the intrusion, control module 150 instructs laser 141 to emit high-power laser to provide a laser heat warning to the intruder and deter them. At the same time, the power adjustment unit dynamically adjusts the laser power according to the real-time distance to ensure effective deterrence while avoiding accidents. Throughout the entire process, control module 150 continuously records the system's operating status and intrusion event information for subsequent querying and analysis.
