On the PLC in the automatic door control system
In supermarkets, public buildings, banks, hospitals and other imported, often using the automatic door control system. The early automatic door control system uses relay logic control, has gradually been phased out. PLC controlled automatic doors as a low failure rate, can be * high, convenient maintenance, which is widely used.
two basic requirements for automatic door control
1 was close, the door should automatically open.
2 door opened, the state should be kept open until the door until the channel is no longer anyone.
3 channels such as the door is no longer any person, the door must automatically close in a very short period of time.
three automatic door control enhancements
order to improve control and enhance the user-friendly, automatic door control can add the following features.
1 connection additional control switch: open the door - Automatic - closed.
2 connections beepers to alert when the goalkeeper to close.
3 hours or under the direction of open the door. For example, open only during business hours, at the store does not open, only to go from inside to outside, the door to open.
4 PLC selection and program design
we use the German Siemens company s LOGO! 230RC universal logic control module. The control module fully functional, easy to use flexible, performance can * can be described as inexpensive.
automatic door according to the previously mentioned work processes, can easily complete the LOGO! Wiring and programming.
1 LOGO! Wiring diagram
K1 open the main contactor
K2 to close the main contactor
S1 (Normally Open) closed limit switch
S2 (Normally Open) open limit switch
S3 Control Switch (door - Automatic - closing)
B1 (normally open contact) outside of the infrared motion detector
B2 (normally open contact) inside the door of the infrared motion detector
2 LOGO! The function block diagram
3 motion detector
during business hours, if someone from the outside (or from the inside out) through the gate, then the motion detector B1 (or B2) closed the motor open the door. In a store close time, motion detector B2 continues to open the door through motor 1 hour to allow customers time to leave the shop; the motion detector B1 is no longer control the motor open, so people outside can no longer access to the shops.
4 door control
door control as the control switch S3 in turn divided into two cases here. When the call to the open position S3 (15 closed), Q1 output controls the motor, the door opened and has been in the open state. When the S3 automatically allocated to the position (15,16 are disconnected), if the motion detector (B1 or B2) has been detected close to the door and the door was not fully open (limit switch S2 is not broken), the Q1 output control Electric door.
5 close control
close control as the control switch S3 of the connected location are divided into two cases. When the call to the closed position, S3 (16 closed), Q2 output controls the motor, the door closed and has been in off state. When the S3 automatically allocated to the position (15,16 are disconnected), if the motion detector (B1 or B2) has been detected close to the door and the door is still noNot fully closed (limit switch S1 is not broken), the Q2 output control motor closed.
6 Buzzer control
when the goalkeeper to be turned off, Q3 output, a second buzzer to prompt pedestrians.
5 Conclusion
using LOGO! Control automatic doors, you can give full play to the high reliability and robustness of PLC characteristics, external wiring simple, flexible, easy maintenance, is a good way effective.
