The Garage Automatic Door System Design
Abstract: With the pace of the society forward, the gradually into a well-off society in the 21st century, people live a happy life to live and work in peace and contentment. People will become more and more high to the requirement of quality of life, in terms of travel, people have changed from walking to driving, so, the auto industry in China occupies an important position in the market economy. Development of our automobile industry, drives the development of a series of related industries, for example, vehicle maintenance and repair, and gasoline, tires, brakes, etc., the garage door is one of them. Therefore, automatic garage door has a large market potential, this article is in view of the previous single chip microcomputer control automatic door garage for further improvement, garage automatic door is controlled by programmable logic controller.
