Technical Field

[0001] The utility model belongs to the technical field of monitoring equipment, and in particular relates to a disaster early warning monitoring device based on machine vision. Background Art

[0002] The disaster early warning monitoring device is a system that uses advanced technology to conduct real-time monitoring and early warning of natural disasters (such as earthquakes, floods, landslides, etc.). It can timely detect and predict disaster risks by collecting and analyzing various signs and data before a disaster occurs, and provide timely and effective information support for disaster prevention and mitigation, thereby reducing the losses caused by disasters.

[0003] In the prior art, machine vision disaster warning monitoring devices have played an important role in the field of disaster prevention and mitigation, but there are still obvious shortcomings. Among them, the most prominent problem is that these devices often lack sufficient flexibility and adaptability. Traditional machine vision monitoring equipment usually uses fixed cameras. Once their installation position and angle are determined, it is difficult to adjust them in real time, which limits their comprehensive monitoring capabilities of the disaster site. Especially in the face of disasters such as landslides and floods, the dynamic changes of the disaster site are rapid, and the camera needs to be able to flexibly adjust the height and angle to capture more extensive and accurate disaster information. However, the fixed cameras in the prior art often cannot do this, resulting in blind spots and dead ends in the process of disaster warning and monitoring, and it is impossible to provide comprehensive information on the disaster site in a timely and accurate manner, thereby affecting the accuracy and efficiency of disaster warning. Improvements need to be made. To this end, a disaster warning monitoring device based on machine vision is proposed. Utility Model Content

[0034] When in use, the disaster warning monitoring device is fixedly installed on the ground through the bottom frame 1, and the disaster warning monitoring device is ensured to be in a horizontal state during installation;

[0035] When the disaster warning monitoring device needs to adjust the height and angle of the camera array 9, the motor 2 111 in the horizontal bar 2 is started, and the screw rod 115 is driven to rotate through the driving wheel 112, the driven wheel 113 and the belt 114. The rotation of the screw rod 115 causes the U-shaped rod 4 threadedly connected thereto to slide up and down in the sleeve rod 3, thereby changing the height of the camera array 9;

[0036] Start the motor 6 on the mounting column 5, and drive the movable column 7 to rotate on the mounting column 5 through the fixed connection between its output shaft and the movable column 7. The rotation of the movable column 7 will cause the movable plate 8 to rotate around the movable column 7, thereby adjusting the horizontal angle of the camera array 9;

[0045] A level is provided on the bottom frame 1, and the level is electrically connected to the controller;

[0046] The level meter monitors the horizontal state of the bottom frame 1 in real time and sends the data to the controller.

[0048] The infrared distance sensor is installed on the mounting column 5 to detect the distance between the U-shaped rod 4 and the horizontal bar 2 in real time. When the U-shaped rod 4 slides on the screw rod 115, the infrared distance sensor will monitor the distance change in real time and send the data to the controller.

[0049] Working principle:

[0050] When in use, the disaster warning monitoring device is fixedly installed on the ground through the bottom frame 1, and the disaster warning monitoring device is ensured to be in a horizontal state during installation;

[0051] When the disaster warning monitoring device needs to adjust the height and angle of the camera array 9, the motor 2 111 in the horizontal bar 2 is started, and the screw rod 115 is driven to rotate through the driving wheel 112, the driven wheel 113 and the belt 114. The rotation of the screw rod 115 causes the U-shaped rod 4 threadedly connected thereto to slide up and down in the sleeve rod 3, thereby changing the height of the camera array 9;

[0052] Start the motor 6 on the mounting column 5, and drive the movable column 7 to rotate on the mounting column 5 through the fixed connection between its output shaft and the movable column 7. The rotation of the movable column 7 will cause the movable plate 8 to rotate around the movable column 7, thereby adjusting the horizontal angle of the camera array 9;

[0053] The output shaft of the electric push rod 10 is rotatably arranged on the side of the movable plate 8 away from the camera array 9. The telescopic action of the output shaft of the electric push rod 10 can assist the movable column 7 under the movable plate 8 to deflect up and down, thereby adjusting the vertical angle of the camera array 9;

[0054] The solar panel 14 converts solar energy into electrical energy and stores it in the battery 13. The battery 13 provides power support for the entire disaster warning monitoring device, including the power requirements of the motor 1 6, the camera array 9, the electric push rod 10, the motor 2 111 and the controller. Through this green and sustainable power supply method, the device is guaranteed to continue to work in an environment without power supply such as the wild.

[0055] The controller receives data from the camera array 9 and other sensors, and performs analysis and judgment based on a preset algorithm. According to the analysis results, the controller can automatically control the operating status of the motor 1 6, the camera array 9, the electric push rod 10 and the motor 2 111 to achieve automatic height and angle adjustment of the camera array 9. The controller can also receive instructions from the remote control center to remotely control and adjust the device.

[0056] When the device needs to be fixed, the fixing nail 15 and the fixing nail 2 16 can be slid and fixed to firmly fix the bottom frame 1 on the ground or other supports. The connecting block serves as an intermediate connecting piece to ensure the stability and reliability between the fixing nail 15 and the fixing nail 2 16. This double fixing method enables the device to maintain stable operation even in complex environments or severe weather conditions.

[0057] The level meter monitors the horizontal state of the bottom frame 1 in real time and sends the data to the controller. It can detect the horizontality of the bottom frame 1 before and after installation, which is convenient for operators to install and also convenient for subsequent detection of natural disasters;

[0058] The infrared distance sensor is installed on the mounting column 5 to detect the distance between the U-shaped rod 4 and the horizontal bar 2 in real time. When the U-shaped rod 4 slides on the screw rod 115, the infrared distance sensor will monitor the distance change in real time and send the data to the controller. The controller can accurately control the lifting height of the U-shaped rod 4 (i.e., the camera array 9) based on the data of the infrared distance sensor to ensure that the camera array 9 can accurately reach the predetermined position for monitoring.

[0059] The disaster warning monitoring device based on machine vision is equipped with an autonomously retractable camera array 9, which can automatically adjust the height and angle of the camera according to the type of disaster and monitoring needs. When disasters such as landslides or floods are detected, the camera array 9 can automatically extend to a higher position to obtain a wider field of view.
