The Control System Design of Building Automatic Door Based on Single-chip Microcomputer
Abstract: As technology continues to develop, automatic doors in people's daily life disruption has been widely applied, and its performance in terms of safety and the increasingly high demand. The design of the main infrared sensor as the sensor used, the received signals into electrical signals pass microcontroller. Stepping motor is a driving apparatus of zhe gate. Stepper motor is controlled by single-chip, so that the door opens automatically. When a person entered into the door, the door closed automatically. The remote controller can also make the door open or closed. In addition, the system also has fault detection and display circuit, increasing its security. The advantage of this design is simple hardware circuit, software, perfect function, and the control system is reliable, high cost, etc. It has a certain value.
Key Words: Automatic doors; single-chip; pyroelectric infrared sensors; fault detection.
