Description

Technical Field

[0001] The present invention relates to the technical field of dangerous goods warehouses, and specifically to an inspection drone for dangerous goods warehouses, and in particular to a control system of an inspection drone for dangerous goods warehouses. Background Art

[0002] Dangerous goods play a particularly important role in the development of various industries, but they are also extremely dangerous. Fire and explosion accidents caused by chemical hazardous goods will pose a serious threat to human life and property, and cause serious damage to the ecological environment on which humans depend for survival. Dangerous goods warehouses are places for storing and keeping flammable, explosive, toxic, radioactive, corrosive and other dangerous goods, and effective monitoring of dangerous goods warehouses is crucial.

[0003] Dangerous goods warehouses are different from ordinary warehouses. They are highly sensitive, catch fire quickly, spread fiercely, and are prone to explosions. However, the existing human firefighting system has a slow response and is difficult to detect weak fire points. Once the fire spreads, it cannot be controlled. Existing automatic firefighting systems mostly use water as a fire extinguishing agent, which cannot be used in dangerous goods warehouses in most cases. They have a slow response speed and low positioning accuracy. They cannot quickly and accurately lock the fire point and extinguish the fire, resulting in continued combustion or even explosion. Moreover, the existing technology cannot identify dark fire points that only produce smoke without open flames, and can only wait for open flames to be generated before handling, which misses the best time to extinguish the fire. At the same time, the existing technology lacks corresponding inspection devices for arson by people who sneak into the warehouse. Summary of the invention

[0004] The purpose of the present invention is to provide a patrol drone for hazardous goods warehouses, which has high patrol efficiency, uses monitoring probes to transmit images to a control box, and can also adjust the spray support plate to control the working angle and working range of the spray fire extinguishing, so as to solve the problems raised in the above background technology.

[0019] 2. The rotor rotates to make the drone take off. The operator remotely controls the drone to inspect the hazardous materials warehouse, monitor the probe and transmit data back through the data antenna; the main control module, spray area automatic detection module, infrared fire detector, temperature and humidity detection module, water pipe solenoid valve, and fire channel feedback module are set in sequence. When the infrared fire data and smoke data transmitted back indicate that there are characteristics of a fire somewhere, the operator controls the drone to fly to that place and uses the monitoring probe to conduct a detailed investigation. The operator sends a signal to the main control module through an electrical signal, which can spray the fire extinguishing agent to the fire. The rotor blows air downward, so that the fire extinguishing agent in the water tank can be sprayed to the fire more quickly, thereby improving the monitoring and treatment effects.
