Example Embodiment

[0024] Example one:

[0025] Such as Figure 1-2 As shown, the embodiment of the present invention provides a multi-spectral aerial surveying and mapping module, including a drone. The drone interacts with the collision avoidance warning module. The collision avoidance warning module makes timely predictions to avoid accidental control of the drone. When an air collision occurs, the drone is connected to the multi-spectral surveying and mapping module, and the multi-spectral surveying and mapping module is used to realize the aerial surveying and mapping. The multi-spectral surveying and mapping module is connected to the optical lens cleaning module. The optical lens cleaning module is used to clean the optical filter of the multi-spectral mapping module. The power system of the man-machine provides power for the collision avoidance warning module and the multispectral surveying and mapping module, so that the collision avoidance warning module and the multispectral surveying and mapping module have energy to operate normally. The collision avoidance warning module recognizes the situation around 200M of the drone, and the 200M recognition range makes The drone can avoid fixed obstacles or expel moving obstacles in time, effectively avoid obstacles in advance, and avoid aerial collisions. The optical lens cleaning module is a scraper-based cleaning device that cleans the position filters of the multispectral mapping module.

[0026] The collision avoidance warning module includes a collision warning radar. The collision warning radar is connected with an imaging prediction system. The imaging prediction system is connected with an aerial bird repellent module, an automatic hovering module and a data recording and analysis module, an automatic hovering module and a drone control terminal Connected, when the automatic hovering module is activated, the drone maintains a vertical height and does not move horizontally, so that it can move after removing the obstacles.

[0027] The specific operation method of the anti-collision warning module is as follows:

[0028] S1. The collision warning radar can be started when the UAV is running, and the signal will be transmitted to the imaging prediction system when the collision warning radar detects an obstacle;

[0029] S2. The imaging pre-judgment system recognizes the signal of the sensed object. If the sensed object is a moving object, it can be judged as a bird, and the signal can be transmitted to the aerial bird repelling module, and the aerial bird repelling module can be activated to remove flying birds. Drive away, if the sensing object is a non-moving object, it can be judged as a fixed obstacle, and the signal can be transmitted to the automatic hovering module. Whether it is a moving object or a non-moving object, the signal is transmitted to the data recording analysis module for storage ;

[0030] S3. When the automatic hovering module receives the signal, it will transmit the signal to the drone control terminal, and control the drone to hover through the drone control terminal;

[0031] S4. When the data recording analysis module receives the data, it counts and classifies the moving obstacles and non-moving obstacles in the fixed area.

[0032] The aerial bird repellent module is a device based on a strobe light and ultrasonic generator. When the aerial bird repellent module is activated, the strobe light and ultrasonic generator are activated to scare away the birds. The birds are more sensitive to ultrasonic waves and feel abnormal Birds will stay away during sound waves to avoid collisions.

[0033] The data recording and analysis module is an integrated device based on a microprocessor, GPS and storage device. The measurement area is modeled by GPS, and the traffic is restricted. The measurement area is set in the microprocessor for moving obstacles and fixed obstacles. The upper limit of the value. When the detected value exceeds the upper limit of the setting, the drone will issue an early warning of frequent accidents when measuring the same area next time, reminding you to handle it carefully. The UAV is a high-power diesel UAV. When the UAV is running, the power supply system is charged by diesel, so that as long as the UAV runs the collision avoidance warning module and the multispectral surveying and mapping module, there is energy to support the operation.
