OYES- Plc200 application resolution - series PLC in the automatic door control Industrial control -

Abstract: with the intelligent is finding wider and wider application, the early automatic door system adopts relay logic control, high failure rate, poor reliability, maintenance difficulties, has been phased out. Controlled by PLC automatic door because has the advantages of low failure rate, high reliability, easy maintenance, and widely used. This paper introduces the OYES - 200 series in the application of automatic door control, through which to design the most intelligent security response speed and fast solution. The development trend of automatic door industry 1. Intelligent, multi-functional; Able to automatically detect open closed stroke position, automatically to adapt to the changes in the hydrodynamic resistance, barrier protection sensitivity to always maintain a higher.

2。 Free maintenance; Take various measures to reduce the maintenance work in the process of use.

3。 Diversity; According to user requirements, the production of all kinds of different appearance and function of the product.

4。 High security; Not a clip or don't open the door. Automatic door control system design scheme 1. Automatic door functional requirements

this design applies most hotels, shopping malls, Banks, building entrance, and according to this, the design of automatic door needs to have the following control functions.

a. Open closed control should be manual and automatic way, in order to maintain convenient.

b。 Emergency stop, when there is a clip or emergency can rapidly be stopped.

2。 Automatic door control requirements:

figure - 1

automatic door control as shown in figure - roughly 1.

a. When people enter the infrared sensor area, open the door motor, automatic door open, open the door until it stop bits, fast to stop bits should join the slowdown.

b。 Open the door (after 7 seconds Time can be set up free length) , if no one in the infrared sensor ellipse area, shut down the motor start, door closed, until it is closed to stop, fast to stop bit needs to slow down the jam.

c。 If someone into in the process of closing, the infrared sensor ellipse area, the door shut, should immediately stop the implementation of open action.

d。 Also need a scram button and automatic and manual switch button I/O distribution point (

USES a OYES200CPU224c)

I2. 0 manually closing

Q0. 0 control motor are turning to open the door

Q0. 1 control motor reversal closed

Q0. 2 motor slow output programming is as follows:

program description: 1. Automatically not manually when, need to manually switch, stop stop button can be used as a manual operation.

2。 I0. 0 induction to someone, automatic door, automatic shutdown after 7 seconds, if someone in the process of closing, automatically open the door. Summary USES PLC as the core to control, its circuit structure is simple, unit circuit respectively through the schematic design, completed by ladder diagram language design, using the conditions provided by the laboratory to simulate and validation procedures, and use the light to realize system functions, control occasions is very suitable for daily life. In actual application of this design may need to do some changes to meet the requirements. Use the simplest way to implement the intelligent operation is the direction of future development. The use of PLC market will be more and more widely, intelligent automatic for all walks of life, research and development products customers need.
