【 Weak current College 】 automatic door's basic Constitution---Power By 【 China power house network 】

Automatic door of many types, structures are different. But the basic structure there are three most, that is, the door frame parts, drive and drive parts, control, and sensor detection section.

1.1 composition of door

The door is the automatic door body parts, due to various types of bodies of surface features and three-dimensional features, thus the composition of the door there are two methods, namely plane composition and dimensional structure.

(1) the door of the plane construction method. Plane construction method is to constitute the body shape elements in accordance with certain rules and principles to create create two-dimensional space plane shape.

The basic plane construction method is to repeat. Repeating form has two methods:

1) basic repetition. In the design of the continuous use of the same basic graphics.

Repeat 2) skeleton. In the design of the door of the cross skeleton module reuse. The most simple and commonly used is a square. It consists of a vertical box, such as distance to the horizon. In the square, on the basis of the framework can have the following changes:

A narrow, narrow, percentage change make a square frame into a rectangular box.

B, direction changes. Make repeat skeleton Unit of horizontal or vertical direction tilts and balance the direction of the armature.

C, a procession moved. Retain a skeleton Unit is in a vertical or horizontal, another unit to do a regular or irregular, the skeleton of the translation into strips.

D, skeleton, cell reflection. The direction of the armature can constitute crisscross repeat of reflection between rows. In reflection on the edge of the frame must be parallel straight lines.

E, skeleton Unit combined.

3) door design using duplicate jibenxing and skeleton, constitute the door structure of two-dimensional space.

⑵ the dimensional structure of the door. Three-dimensional design consisting of a body, not like the graphic design of the shape. Three-dimensional design mainly will form elements, in accordance with the provisions of principle into practical, innovative, three-dimensional space it can form from any direction you can feel the true body.

Stereoscopic method in two ways:

1) plane geometric shape. It consists of four or more of the surface, the intersection of the plane interconnected to form a space.

2) geometric surfaces. It consists of several surface body composition. It consists of geometric curve-shaped edge of plane around the straight line motion, its trajectory will form a surface.

These are the design of the door of the basic methods and principles in the door design should make full use of the above train equipped with door shape, post and flower shape to avoid imbalance in the overall aesthetic effect of the door.

1.2 drive device and actuator

Automatic door drive unit by the motor and reducer or tap and hydraulic systems, in accordance with the instructions of the control device drive driving equipment work at set procedures, to drive door open or closed. From the drive to the movement of the door and, to a transmission mechanism, reducer is part of the drive mechanism. Now, most of the reducer and motor is integrated, as a reducer, which causes the device to simplify, standardize, small size easy to do. In addition to the reducer, according to the specific needs of design drive mechanism. Actuator can be one of the gears, chain drive, or it can be a highly efficient synchronous belt drive.

1.3 control and sensor detection device

Controller is a micro computer as the main body of the control device that receives a signal detection sensors, drives, complete and close the door.

The sensor is automatically detect human body or by manual operation will detect heart good hull to the controller's device or devices.
