　　Wireless remote-controlled or programmable solar-powered bird-repelling gas cannons are specifically designed for bird control over airport runways. They are environmentally friendly, do not harm birds, deliver excellent results, and require low operational and maintenance costs.

　　Wireless remote control/programmable solar-powered bird-repelling gas cannon – Scope of application:

　　It is suitable for use at civil and military airports as well as in the power industry to effectively scare away and drive off various bird species and small animals. It does not harm birds or other wildlife, maintains ecological balance, and, by harnessing solar energy, conserves resources and meets environmental protection requirements.

　　Main features of the wireless remote-controlled/programmable solar-powered bird-repelling gas cannon:

　　1. This gun boasts a compact size, light weight, high firepower, long control range, and the capability for unattended operation. Its control system is entirely based on computer chips, ensuring stable and reliable performance with a low failure rate.

　　2. The programmable control equipment allows users to freely set the power-on and power-off times, as well as the automatic firing time; once the input parameters are configured, the gas cannon can operate autonomously.

　　3. The remote-control equipment has a coverage area that extends across the entire airfield, with no impact on airport and flight communications at the operating frequencies.

　　4. The gas cannon features a stainless steel structure, and its control section is rated IP65, making it suitable for long-term operation under harsh weather conditions.

　　5. The power supply system utilizes a 12V maintenance-free storage battery charged by solar panels, eliminating the high costs associated with cable installation.

　　6. Installation and maintenance are extremely convenient. The end user can freely modify the configuration, shape, and firing mechanism according to their specific requirements. Detailed explanation of the solar-powered bird-repelling gas cannon.

　　7.1 Technical Principle

　　The BR-20A bird-deterrent shock-wave cannon vehicle is a device that uses high sound-pressure and air-field-control technologies to repel birds. It employs a throttle valve and solenoid valves to inject a precisely measured amount of compressed fuel gas into the cannon barrel, where it is pre-mixed with the air inside. An electronic ignition system, controlled by a time relay, regulates the frequency of combustion and explosion. The resulting high-pressure gas, after passing through a turbulence-generating device, forms a nonlinear shock wave airflow, creating a turbulent air field extending approximately 2,000 meters and generating sound pressures exceeding 200 dB. Birds, startled by the turbulent airflow and the intense sound pressure, quickly flee, thereby achieving effective bird deterrence.

　　7.2 Structural Composition

　　The BR-20A shockwave cannon vehicle primarily consists of a pickup truck, a bird-deterrent shockwave cannon, an explosion-proof gas cylinder cabinet, shut-off valves, and a backup power supply.

　　The pickup truck is the JMC Yuhu EV all-electric pickup, with the following specifications:

　　2) Vehicle Introduction

　　7.2.2 Bird-Repelling Shockwave Cannon

　　The bird-repelling sonic cannon primarily consists of a cannon barrel, a rotatable and elevatable pan-tilt unit, an ignition system, a combustion chamber, an electrical control system, an oxidizer generator, and a remote control, as detailed below:

　　(1) Gun barrel

　　The gun barrel is integrally formed from 5-mm-thick stainless steel and incorporates an internal shock-wave turbulence generator, which converts the explosive gas flow into a shock wave to disrupt the forward airfield.

　　(2) Rotating and Elevating Pan-Tilt Unit

　　The rotary elevation gimbal enables 360° horizontal rotation and 60° vertical elevation adjustment of the gun barrel, allowing precise targeting—wherever the bird is, aim directly at it—ensuring the bird is always under the menacing gaze of the muzzle.

　　(3) Combustion Chamber

　　The combustion chamber is constructed from 15-mm-thick stainless steel to ensure safety, and is equipped with two ignition devices that extend deep into the chamber to mitigate high-pressure hazards. The igniters utilize dual iridium-platinum needle-type spark plugs, with nickel-plated housings and sealing gaskets; the spark plug tips are made of ceramic insulators, providing excellent insulation, heat dissipation, impact resistance, and mechanical strength. A wiring nut at the base of the insulator facilitates connection to the ignition coil.

　　(4) Electrical Control System

　　The electrical control system, which comprises drivers, voltage converters, wireless transmitters, and circuit control units, is the core component of the bird-deterrent shockwave cannon. It can be connected to a computer to adjust the cannon’s firing parameters, allowing for tailored settings based on specific bird activity levels. This enables precise control over the amount of combustible gas used, optimizing gas utilization and enhancing overall efficiency.

　　(5) Combustion-supporting gas generator

　　The combustion-supporting gas generator is a variable-frequency fan, with the following parameters:

　　(6) Shut-off valve

　　Pilot-diaphragm solenoid valve, with the following specifications:

　　(7) Remote control

　　The remote control uses a standard 9V battery, and a single remote can operate multiple shockwave cannons with no limit on the number. Under normal conditions, the battery in one remote can last 5–6 months, with a maximum operating range of up to 100 meters. Operation is simple and extremely convenient.
