Guizhou Guanglian Technology Co., Ltd. Integrates research, development, design, production, and sales. Currently, the company focuses on hardware and produces products such as animal capture machines and balance control landing machines. Animal capture machines have obtained multiple national patent achievements. The balance control landing machine is designed to protect a certain farmland from animal damage. It is installed around a protected area, and as long as there is gravity on the ground entering from around, all animals and human made equipment invading the protected area will fall into traps. This is the significant role of the balance control machine in protecting a certain area. That is to say, the area protected by the balance control landing machine is not affected by all enemies entering from the ground.
