1. Content summary.

At the entrances of supermarkets, public buildings, banks, hospitals, etc., automatic door control systems are often used. The early automatic door control system used relay logic control and has been gradually phased out. PLC control automatic doors have been widely used due to their advantages of low failure rate, high reliability and convenient maintenance.

Due to the wide speed regulation range of the DC motor, the speed regulation characteristics are smooth. The DC motor has a strong overload capacity and a large thermal and braking torque, so the actuator uses a DC motor.

2: Design content requirements.

1. The hardware composition of the automatic door control device: the automatic door control device is composed of the photoelectric detection switch K1 inside the door, the photoelectric detection switch K2 outside the door, the limit switch K3 when the door is opened in place, the door is closed to the limit switch K4, the door opening actuator KM1 (the DC motor rotates forward), the door closing actuator KM2 (the DC motor is reversed) and other components.

2 control requirements: 1) When someone passes the photoelectric detection switch K1 or K2 from the inside to the outside or from the outside to the inside, the door opening actuator KM1 acts, the motor rotates forward, and when it reaches the position of the door opening limit switch K3, the motor stops running. 2) After the automatic door stays in the door opening position for 8 seconds, it automatically enters the door closing process, the door closing actuator KM2 is started, the motor is reversed, and when the door moves to the position of the door closing limit switch K4, the motor stops running.

3. In the process of closing the door, when there are personnel from the outside to the inside or from the inside to the outside through the photoelectric detection switch K2 or K1, the door should be stopped immediately and automatically enter the door opening procedure.

4. During the 8-second waiting time after the door is opened, if there are personnel passing through the photoelectric detection switch K2 or K1 from the outside to the inside or from the inside to the outside, they must start waiting for 8 seconds again, and then automatically enter the door closing process to ensure the safe passage of personnel.

Three: design principle.

a) Hardware circuit part.

As shown in Figure 1, the initial state gate is closed. When the photoelectric detection switch K1 or the photoelectric detection switch K2 outside the door moves, the output Y000 is set by the programmable controller, the door opening actuator KM1 is driven to act, the DC motor M is turned on, the voltage of 24V is input to the positive pole of the DC motor, the motor is rotated, and the door is opened, when the door is opened to the limit switch K3, Y000 is reset, the output is stopped, the door opening actuator KM1 is disconnected to make the motor stop rotating without voltage input, and wait for 8 seconds in the stop stage, after the pedestrian passes normally.

Find the automatic door control device PLC ladder control program 1The hardware composition of automatic door control device: automatic door control device is made up of components such as photoelectric detection switch K1 in door, photoelectric detection switch K2 outside door, door opening in place limit switch K3, door closing to limit switch K4, door opening actuator KM1 (make DC motor rotate forward), door closing actuator KM2 (make DC motor reverse) and other components.

The photoelectric detection switch is ON for detecting a person or object, otherwise it is off. 2 control requirements: 1) When someone passes the photoelectric detection switch K1 or K2 from the inside to the outside or from the outside to the inside, the door opening actuator KM1 acts, the motor rotates forward, and when it reaches the position of the door opening limit switch K3, the motor stops running.

2) After the automatic door stays in the door opening position for 8s, it automatically enters the door closing process, the door closing actuator KM2 is started, the motor is reversed, and when the door moves to the position of the door closing limit switch K4, the motor stops running. 3. In the process of closing the door, when there are personnel from the outside to the inside or from the inside to the outside through the photoelectric detection switch K2 or K1, the door should be stopped immediately and automatically enter the door opening procedure. (4) During the 8S waiting time after the door is opened, if there are personnel passing the photoelectric detection switch K2 or K1 from the outside to the inside or from the inside to the outside, they must start waiting for 8S again, and then automatically enter the door closing process to ensure the safe passage of personnel.

A PLC is more than just a circuit. The access control system is designed with sound and speakers. Locking is involved, and it is necessary to press the key to unlock. Involving the opening and closing of the motor. Involving a switch induction probe, to a sensor. PLC is to write programs, not circuit boards.

The input signal is given to the logic processing of the signal and the output is believed to be signaled by a relay control mechanism.

Is it okay to have a radar fast sensing door.

This is simple, the question is what series of PLC do you use, as well as the model, whether the positive and negative control is used with frequency conversion, or AC contactor, you have to make it clear, otherwise how can others return to you?

I'm pretty sure you're going to write a program.

But I don't know if you want to write **.
