The main working principle of automatic door open and close is to sense an object next to the door with the help of sensors and give this input to the PLC for the opening and closing operation of the door.

The figure of the automatic door in life can be seen everywhere. The main working principle of the automatic door is to sense whether there is an object passing through the sensing device at the top of the door and the auxiliary infrared sensing device on the side of the door frame, giving the door a switch signal and then programmable control. The device, the frequency converter, the drive motor and the transmission control the movement of the door leaf to realize the function of opening and closing the door.


The biggest feature of the automatic door is that it can complete the automatic door opening and closing action without being supervised, which gives people great convenience, but the biggest problem in the case of no one is the safety hazard. The popularity of automatic doors in China is not wide enough, which leads to the slow development of automatic doors. The system construction relies mainly on imports. The control part of the hardware cannot meet the market demand. The software design is relatively simple, and the designed system is relatively simple [1] . These can determine the automatic door, the stability and safety of operation, so China needs to strengthen the research of control system, combined with the foreign automatic door function and local actual needs, using advanced software compilation, solving various problems existing in the development process of automatic door, and promoting the automatic door industry.


The design of this paper is an automatic door applied to public places such as shopping malls and high-end hotel entrances and exits, which require strong security and practicality. Integrating automatic door scenes and usage habits in daily life, this paper designs the most used automatic sliding door [2] . The automatic sliding door uses the inductive switch and safety grating to realize automatic control. At the same time, the manual control is realized by using the operation buttons, and the use is made. Auxiliary devices such as backup power supply to meet the needs of different situations of adult traffic.


The design of the automatic door needs to be considered for the purpose of safety and simplicity. This design is applied to public places with large traffic flow. It is designed to take care of the practicality of practical use and improve convenience [3] . The design of automatic door control system based on PLC needs to consider the practicality and safety in real life, and ensure the safety of the passing object under the guarantee of smooth operation of the automatic door. This paper adopts the photoelectric sensor to collect whether the object passes the signal to the PLC, and controls the opening and closing of the automatic door through the inverter, the driving motor and the transmission device in the PLC control actuator; meanwhile, the infrared sensor is opened after the automatic door is opened. Let the relevant implementing agencies coordinate work to ensure that the automatic door can operate normally and safely, as shown in Figure 1.


The main content of the automatic door control system design process includes the following aspects: master the control principle and control flow of the automatic door, and understand the control process of the automatic door as a whole. The input signal device and the output control device are clearly designed, and the number of input and output points is estimated in combination with the requirements of the automatic door function design. Select the appropriate PLC type based on the number of I/O points. According to the number of


I/O points, the input and output addresses are reasonably distributed, and the terminal wiring diagram is drawn, which is beneficial to the design of the ladder diagram and the convenience in using the simulation. Draw a complete ladder diagram according to the curriculum design requirements and practical applications. Use software simulation to export the program to the specified format and run the simulation to see if the function is implemented [4] . Troubleshoot and unreasonable troubleshooting procedures, optimize program design; optimize overall debugging of automatic door systems, optimize problematic programs, and continuously improve the system through repeated simulations until the desired functions are implemented.


In this paper, the drive motor drives the transmission device to realize the opening and closing of the automatic door. The operation of the motor is realized by the AC frequency controlled by the PLC to control the frequency converter to supply the motor. The advantages of this design are easy operation, stable operation and high real-time performance. Compared with other types of motors, more mature AC motors can control cost, have stable torque output and a larger speed range. Improve the stability of the long-term operation of the automatic door, the system hardware components, as shown in Figure 2.


The transmission of the automatic door is mainly composed of a drive motor, a transmission belt and a transmission pulley. Considering the convenient installation and maintenance, the transmission only occupies a small part of the whole system. For example, the pulley that drives the door body needs to be fixed outside the wall to be detachable structure. The three-phase asynchronous motor is selected as the drive motor. Passing three-phase symmetrical alternating current into the stator winding of the motor generates a circular rotating magnetic field. In the magnetic field, the rotor winding cuts the magnetic field to generate an induced current, and the rotor winding in the closed path also generates an electromagnetic force. Under the interaction of the two magnetic fields, the motor, the electromagnetic torque in the same direction as the rotating magnetic field is formed on the rotating shaft, so that the rotor of the motor rotates [5] .


The I/O address allocation of the automatic door control system is written according to the number of input and output signals required by the automatic door control system, and are also the index data for writing the PLC program and performing system debugging. According to the estimation of the number of input and output addresses, the design selects the CPU 226 as the configured S7-200 PLC, and needs to input 12 points and 14 output points [7] .


There are two kinds of alarm conditions in the automatic door. The first one is the automatic door program. The automatic door appears to be operated manually or automatically (Q0.0 or Q0.2) and closed (Q0.1 or Q0.3). The door will judge by the program, the M0.1 action will stop the whole automatic door control system, the fault light Q1.1 will light up, remind the staff to come to check, after checking no problem, press the abnormal reset button I1.3 to make the automatic The gate program is reset.


When the automatic door encounters an emergency, and presses the emergency stop button I0.1, the automatic door stops all work, the alarm Q0.4 and the alarm light Q0.5 work at the same time. After the check is normal, it presses the abnormal reset button I1.3 automatically. The door is re-worked. The automatic door in the text is mainly composed of two control modes, manual control and automatic control of the opening and closing of the automatic door. When the automatic control is run, the actuator is opened and closed according to whether or not someone has changed the frequency of the inverter through the system.

Automatic door opens when the door controller receives an activation signal by the sensor and activate the gear motor to drive the belt and pulley. When no one is detected inside the activation area, the door starts closing after a designated period of time.


The Delta DD series elevator door-control drive is an intelligent drive with outstanding features. These include a modular design for easy removal and installation of terminal blocks, a safety power switch and a built-in digital keypad for quick operation control. The drive has four control modes for opening and closing doors. The distance-control mode is a sensor-free system with an encoder which counts PG pulses to detect the position from the speed. The speed-control mode uses sensors to control the door opening and closing actions. The multi-step speed control mode generates a smooth door opening-and-closing curve using PLC control. The Delta DD series elevator door control drive provides a complete solution for elevator door control.
