Description

Technical Field

[0001] The present invention relates to the technical field of acoustic, optical and electrical integration, and in particular to an acoustic, optical and electrical linkage island and reef unmanned intrusion detection intelligent early warning system. Background Art

[0002] The traditional perimeter security system has a single mode and many monitoring loopholes. For example, video or radar is used as a single monitoring method, which mainly relies on optical means. It lacks the ability to perceive sudden vibrations, sounds and other signals in the environment. In addition, traditional optical monitoring methods also have blind spots in vision. Many engineering projects and important areas have many people climbing intrusions and crossing intrusions due to poor protection. The system cannot provide timely safety warnings, and it is difficult to achieve effective warnings and rapid response management. Although acoustic monitoring methods represented by sound and vibration can cover a large area of ​​ground monitoring areas and effectively monitor personnel and vehicle intrusions, they lack optical dimension monitoring, and the system is not intuitive enough. When a single system is used for warning, maintenance personnel cannot immediately and effectively grasp the alarm situation on site, and natural environmental factors such as the slightest disturbance can easily lead to system false alarms and other problems. Summary of the invention

[0003] In view of this, the present invention provides an unmanned intrusion detection intelligent early warning system for islands and reefs with acoustic, optical and electrical linkage, which can utilize the linkage of acoustic, optical and electrical detection to build a multi-level protection monitoring network and realize intelligent early warning of intrusion detection, thereby greatly reducing the investment in manpower on duty.

[0004] To achieve the above purpose, the technical solution of the present invention is as follows:

[0005] An acoustic-optical-electrical linkage island and reef unmanned intrusion detection intelligent early warning system, comprising an acoustic-vibration detection front end including a front-end sensor, an optical-electrical detection front end including a radar and thermal imaging dual-spectrum integrated intelligent ball camera, an linkage terminal and an intelligent back end, wherein the acoustic-vibration detection front end is responsible for the first-tier detection, the optical-electrical detection front end is responsible for the second-tier detection, the linkage terminal is used for signal linkage convergence, and the intelligent back end is used for realizing analysis and early warning;

[0006] The front-end sensor is installed at a first-line location near the sea perimeter of an uninhabited island or reef, covering a cross-interconnected distance without blind spots; the photoelectric detection front end is deployed at a second-line location behind the front-end sensor;

[0007] After receiving the warning signal from the front-end sensor, the acoustic vibration detection front end triggers the camera to capture the image and transmit it back to the intelligent background, realizing the first-tier early warning tracking; after analysis and judgment, the intelligent background adds the sensor or detection equipment coordinate position and immediately sends it to the photoelectric detection front end for the second-tier detection.

[0008] Among them, in the second stage of detection, the photoelectric detection front end uses key security radar detection and thermal imaging dual-spectrum integrated smart ball camera to realize dynamic video recording.

[0009] Among them, the key security radar detection adopts K band, supports radar detection cross-border detection and regional intrusion event detection, supports secondary review of radar events, and the detection distance is greater than 300 meters; the thermal imaging dual-spectrum integrated smart ball camera supports radar event linkage tracking and capture functions. When the target triggers an alarm, the radar linkage ball camera tracks and captures the target.

[0010] The linkage terminal includes a wireless receiving module, an edge processor and an Ethernet transmission module to realize two-way communication of signals and multi-level linkage long-distance transmission.

[0011] Among them, the intelligent background includes an intelligent analysis and warning module, a visual storage terminal and a data management module, which can realize real-time monitoring, record storage, alarm, classification and analysis and summary of warning events, and provide qualitative analysis of alarm information and processing results.

[0012] Among them, after completing two rounds of detection, the intelligent background gathers and analyzes the alarm information received from the first and second rounds of detection. After confirming the alarm, it pushes the alarm pop-up window and sound including the alarm image, target category, alarm distance and fan-shaped area, and simultaneously launches the duty officer confirmation, alarm classification, and alarm handling response mechanism process.

[0013] The system adopts a multi-zone detection method and cooperates with a zoning algorithm to achieve early warning.

[0014] Among them, the system adopts wireless self-organizing network communication, relying on the self-organizing network of islands and reefs to achieve communication interconnection of all islands and reefs; through the combination of wireless access base stations, wireless relay base stations, and wired access base stations, full coverage of communication transmission of front-end signals is completed.

[0015] Among them, the first batch of warning records are in photo format.

[0016] Beneficial effects:

[0017] 1. The system of the present invention realizes real-time collection and distributed data processing of environmental sound and ground vibration signals through various monitoring means such as sound vibration sensor system, video monitoring system, radar detection system, etc., realizes detection and alarm of pedestrians, vehicles, and aerial targets, and at the same time deploys video monitoring system around monitoring nodes to realize linkage with front-end sound vibration sensors to further enhance the overall monitoring effect. Through various cutting-edge means, using sound, light and electricity detection linkage, a multi-level protection monitoring network is constructed.

[0018] 2. The system of the present invention is aimed at the special harsh environment and application scenarios of uninhabited islands and reefs. It uses a wireless self-organizing network multi-dimensional detection intelligent alarm network to implement long-term unmanned linkage detection in areas with no communication signals, blind spots with communication signals, areas with harsh environments where ordinary monitoring is difficult to achieve, and areas that are difficult for personnel to reach and are very important. It has all-weather detection day and night, full coverage of multi-stage detection, and no blind spots in concealed detection. It is low-cost, low in false alarms, easy to install and maintenance-free.

[0019] 3. In the system of the present invention, when there is no human activity in the monitoring area of ​​the front-end sensor, the detection equipment is in a silent state, and the entire link works in standby mode with the lowest power consumption; the low-power design is adopted, and the low-power management state can be automatically entered from collection, concentration to transmission. Through the cooperation of sensing, algorithms, and system links, single-machine energy saving, linkage energy saving, and system energy saving can be achieved according to actual usage requirements to achieve superior energy-saving management of the entire system. Through special design and processing, the energy consumption of the equipment is lower, the standby time of the equipment is extended, and energy saving and power saving are achieved to meet the actual needs of the special environment of unmanned islands and reefs with tight power supply and no network.

[0020] 4. The system of the present invention realizes static and dynamic detection jointly, which reasonably reduces storage resources. When someone breaks in, the detection device is automatically awakened after receiving the alarm signal from the front-end sensor. After quickly capturing the image, it wakes up the joint terminal through the wireless self-organizing network device and transmits the alarm image to the intelligent background. After analysis, the first acoustic vibration detection target information is sent to the photoelectric detection front end for secondary confirmation; the photoelectric detection front end starts the secondary detection, and the target information is transmitted back to the intelligent background for processing through the wireless self-organizing network; after the two detections and transmission of the alarm image are completed, the self-organizing network link and related equipment re-enter the silent standby state. The system of the present invention adopts a new multiple and multi-zone detection method, which cooperates with the partitioning algorithm to effectively reduce false alarms; at the same time, it adopts a step-by-step detection and a combination of near and far working modes to reduce false alarms and improve the accuracy of early warnings.

[0021] 5. The system of the present invention adopts wireless ad hoc network communication technology, does not require 4G or 5G networks, and relies on the island and reef self-organizing network to achieve communication interconnection of all islands and reefs, which meets the requirements of border islands and reefs. Through the combination of wireless access base stations, wireless relay base stations, and wired access base stations, the communication transmission of front-end signals is fully covered, with high bandwidth, strong anti-interference ability, high security, long single-stage transmission distance, each relay supports 15 terminal accesses, and can realize multi-level wireless relay cascading with negligible bandwidth loss.

Figure 1 As shown, it includes an acoustic vibration detection front end including a front-end sensor, a photoelectric detection front end including a radar and thermal imaging dual-spectrum integrated smart ball camera, a linkage terminal and an intelligent background. The acoustic vibration detection front end is responsible for the first-tier detection and early warning tracking, the photoelectric detection front end is responsible for the second-tier detection, the linkage terminal is used for linkage convergence, and the intelligent background is used to realize analysis and early warning.

[0029] Among them, front-end sensors with cross-connection and no blind spots are installed at the first-line locations near the sea of ​​uninhabited islands and reefs, and are pre-buried in front-line locations such as beaches, reefs, bushes, and mudflats. Each sensor detects human intrusion in the nearby area and sends out an alarm signal in time. The front-end sensor uses wireless communication; after receiving the alarm signal from the front-end sensor, the acoustic vibration detection front end can immediately process and trigger the camera to capture the image and wirelessly transmit it back to the intelligent background to achieve the first-tier early warning tracking. Among them, the first-tier early warning records are in photo format, which can effectively reduce the use of storage resources, and at the same time provide a preliminary judgment direction and basis for the second-tier detection.

After analysis, the intelligent background adds the sensor or detection device coordinates and immediately sends them to the photoelectric detection front end deployed at the second line position 150∽200 meters behind for re-detection, which triggers the second-tier early warning. The second-tier detection uses photoelectric detection technology, and the photoelectric detection front end uses thunder and ball linkage technology, that is, the key security radar detection and thermal imaging dual-spectrum integrated smart ball machine to achieve dynamic video recording, which can supplement more dynamic information of the first tier, complement dynamic and static, and achieve maximum resource utilization, which can greatly reduce the traffic consumption of the overall system and reduce the workload of back-end monitoring personnel. In this embodiment, the key security radar detection adopts K band, which has low power consumption, strong anti-interference ability, supports radar detection of cross-border detection and regional intrusion event detection, supports secondary review of radar events, and has a detection distance of more than 300 meters; the thermal imaging dual-spectrum integrated intelligent ball camera supports radar event linkage tracking and capture functions. When the target triggers the alarm, the radar can be linked to the ball camera to track and capture the target. It can capture faces, human bodies and vehicles, and supports attribute analysis for correlation output, and the detection distance is greater than 250 meters. Between multiple units, the linkage tracking function is supported. When there are multiple targets triggering radar events, the radar can be linked to the ball camera. The ball camera focuses on tracking the closest target and implements dynamic tracking and recording. The photoelectric detection front end in the system of the present invention is as follows: Figure 2 As shown, it includes key point security radar, thermal imaging dual-spectrum integrated smart ball camera and linkage control module.

[0031] The linkage terminal includes a wireless receiving module, an edge processor and an Ethernet transmission module, which realizes high bandwidth, low latency, two-way communication, low power consumption and multi-level linkage long-distance transmission of signals. The single-level transmission distance can reach up to 15 kilometers, and 16 detection devices can be connected at the same time, which can achieve full coverage of the island. Figure 3 shown.

[0032] The intelligent background (base station or monitoring center) includes an intelligent analysis and early warning module, a visual storage terminal and a data management module, which can realize the functions of real-time monitoring, recording and storage, alarm, classification, analysis and summary of early warning events, and can provide qualitative analysis of alarm information and processing results. Furthermore, after completing two rounds of detection, the intelligent background gathers and analyzes the alarm information received from the first round of detection and the second round of detection, and after confirming the alarm, pushes an alarm pop-up window and sound including alarm images, target categories, alarm distances, and fan-shaped areas, and simultaneously launches various response mechanism processes such as duty officer confirmation, alarm classification, and alarm processing. The intelligent background in the system of the present invention is as follows: Figure 4 shown.

[0033] Furthermore, the system of the present invention adopts a multiple and multi-zone detection method, which cooperates with a zoning algorithm to effectively reduce false alarms; at the same time, it adopts a step-by-step detection and a combination of long and short range working modes to reduce false alarms and improve the accuracy of early warnings.

[0034] In addition, the system of the present invention adopts wireless ad hoc network communication technology, does not require 4G or 5G networks, and relies on the island and reef self-organizing network to achieve communication interconnection of all islands and reefs, which meets the requirements of border defense islands and reefs. Through the combination of wireless access base stations, wireless relay base stations, and wired access base stations, the communication transmission of front-end signals is fully covered, with high bandwidth, strong anti-interference ability, high security, long single-stage transmission distance, each relay supports 15 terminal accesses, and can realize multi-level wireless relay cascading with negligible bandwidth loss.
