Description

Organism invasion monitoring and alarm system and method

technical field

Background technique

At present, various large-scale machinery is used in many occasions, the environment is complex and the working range can reach hundreds of meters. The intrusion of non-operating personnel and vehicles cannot be detected and stopped in time, and it is easy to cause safety hazards and cause inestimable risks. In order to reduce losses and losses, the main methods at present are to set up safety warning lines and manual inspections. The warning lines can only serve as a warning, and have little effect on naughty children and caring people. They cannot be discovered in advance, let alone passively stopped. Manual inspection will lead to high labor costs, and it is still impossible to achieve 360 degrees without dead ends.

In response to the above problems, a solution is currently proposed to set up laser fences. This solution is not only costly, but also cumbersome to install, and can only be used on open and flat ground, which has many limitations. Another solution is to install laser radar around the machine to form 3D point cloud imaging around it. This solution has the following problems. The cost of high beam laser radar is extremely high, while the resolution of low beam laser radar is very low at a distance of 100 meters. It is almost impossible to judge the outline of pedestrians and vehicles, and there are many blind spots in the lidar. The laser cannot penetrate obstacles such as walls and metals. Personnel and non-staff entering the monitoring area will interfere with the monitoring.

After searching found:

The Chinese utility model patent "A Station Intrusion Alarm System Based on Radar Monitoring" with the authorized announcement number CN207182593U includes an embedded MCU main control module for managing defense areas and defense states, data communication and man-machine command interaction; audio data Processing system, audio and video system, wireless intercom system, power supply module, and detection radar system; the audio data processing system, audio and video system, wireless intercom system and detection radar system are respectively electrically connected to the embedded MCU main control module . The utility model uses Doppler microwave radar and laser radar to detect the range of about 15 meters from the end of the platform, whether there is a human body or moving object passing by, and immediately starts the on-site alarm and remote alarm information transmission when the intrusion target is found, and notifies the on-site security personnel to rush to the site quickly On-site processing, at the same time, the system integrates video capture and storage technology, and the alarm information is video recorded and image captured as the basis for accident investigation. This method has a small detection range and cannot work on some large machinery. Lidar and microwave radar are greatly affected by surrounding obstacles, and cameras are greatly affected by weather light and obstacles. In addition, this method cannot distinguish between workers and Intrusion personnel cannot accurately realize intrusion monitoring.

The Chinese invention patent application "An Electronic Fence" with the publication number CN110634254A includes a laser radar light curtain device installed at a preset position to form a scanning surface. When the laser radar light curtain device detects illegal intrusion in the scanning surface , send the intruder’s point cloud data to the main controller; process the intruder’s point cloud data to obtain the distance and angle information of the intruder, when the intruder’s intrusion position is within the preset arming area, the main controller that triggers the alarm device alarm device. The above-mentioned electronic fence can scan the surface at the preset position by setting the laser radar light curtain device, and at the same time can send the intruder's point cloud data including distance and angle information to the main controller to locate the intruder's intrusion position , Improve the efficiency of checking intruders. This method uses high-wire beam lidar, which is extremely costly, while the resolution of low-wire beam lidar is very low at a distance of 100 meters, and it is almost impossible to judge the outline of pedestrians and vehicles, and there are many blind spots in the lidar, and the laser cannot penetrate walls, metals, etc. Obstacles have high requirements on the surrounding environment and are greatly affected by fog and rain. In addition, the laser radar cannot distinguish between staff and non-staff entering the monitoring area, which brings interference to the monitoring.

The radar monitoring system is mainly composed of a vital sign detection radar installed on the top of the machine, a conveyor belt, a stepping motor, and an encoder. The vital sign detection radar is used to detect the ultra-low frequency electric field emitted by the heart and lungs of the living body (such as the ultra-low frequency electric field emitted by the beating heart), which can pass through obstacles such as reinforced concrete and steel plates, and is captured by the detection radar. It is used to detect search and rescue survivors, and can distinguish the electric field frequency of people and animals.

The encoder is used to obtain the rotation angle of the motor, which can detect the direction of the radar irradiation in real time, and the data is transmitted to the central processing unit to draw the intrusion monitoring radar map.

The central processing system includes: central processing unit, computing board, embedded control system, CAN communication module and serial communication module, generally installed in the cockpit. The central processor coordinates all data and resources, analyzes and judges radar data, and interacts with various modules. The computing power board provides computing power support for the process of huge amount of calculation that the system may require, such as splicing of radar data, filtering and rendering of visual interface. Because the radar detects a fan-shaped surface, the angle data from the encoder and the data detected by the radar are rotated, accumulated and spliced to obtain a circular surface data, which is more convenient for observation and calculation. Through filtering, some clutter models can be filtered out, including surrounding radio clutter, mechanical disturbance, etc. The methods used are high-pass filtering, low-pass filtering, Kalman filtering and so on. The embedded control system controls the external modules such as the stepping motor of the radar monitoring system and the alarm component of the alarm system, and provides driving pulse data for these modules, such as PWM pulse for controlling the motor, light pulse data and audio pulse data for controlling the sound and light alarm , under the direct control of the CPU. The CAN communication module is mainly connected to the control system of large machinery. When an intrusion target is found to enter a high-risk area, it will automatically control the machinery to stop working to prevent danger.

The serial port communication module mainly communicates with the vehicle, and sends the generated radar image to be displayed on the central control screen of the vehicle, which is convenient for the operator to understand the surrounding situation intuitively. At the same time, the operator can provide the serial port module to import configuration parameters, such as the monitoring range, Early warning range, dangerous automatic shutdown range, can delineate virtual electronic fence, focus on monitoring and early warning designated areas.

The alarm system is mainly composed of high-power horns and LED high-flashing alarm lights installed at the four corners of the machine. When there is a biological invasion, the system will first judge whether it is a human or an animal. If it is an animal, it will emit an infrasonic wave (15-20HZ) that resonates with the animal. , to avoid the resonance frequency of the human body, and control the radiation range) to drive away. If it is a person or a vehicle driven by a person, it will issue a short alarm and inform that it has entered a dangerous operation area, please leave as soon as possible, and flash the alarm light to attract the attention of the other party. When the other party gets closer, the alarm sound will be more urgent, and the alarm light will flash more frequently.

The identification marking system is composed of a power supply battery and an electromagnetic oscillator. The electromagnetic oscillator It can emit an electromagnetic signal that can be clearly captured and recognized by the vital sign detection radar. When the radar recognizes the electromagnetic signal, it will filter out the biological echo within 2m of the electromagnetic signal, and will not be used as an intrusion target.
