Automatic glass overlapping induction door

Automatic glass overlapping induction door

Banks have automatic doors that open and close automatically when someone approaches. Xiao Ming has a strong interest in this, he would like to know how to achieve Automatic Door control. He did this several times: when he approached the automatic door gently, it opened automatically; When a stone is rolled towards an Automatic Glass Door, it opens automatically; When a colorless transparent large glass plate with ball bearings at the bottom is slid upright towards the Automatic Induction Door, the door does not open.

First, the principle of automatic control of the automatic induction door:

When the induction detector detects someone entering, the induction detector will collect signals and generate pulse signals, which will be transmitted to the main control device. After judging, the main control device will inform the motor to run, and monitor the motor revolution at the same time, so as to inform the motor to increase force and enter slow running at a certain time. When the motor gets a certain running current, it runs forward and transmits power to the synchronous belt, and then the synchronous belt transmits power to the spreader system to open the door. After the door is opened, the controller will make a judgment. If it is necessary to close the door, the motor will be informed to move in reverse to close the door.Quick Roll-up Door

Two, the composition of automatic induction door machine:

1. Motor:

An electric motor, "Motors," is a device that converts electrical energy into mechanical energy. It uses electrified coils (namely stator windings) to generate a rotating magnetic field and uses the closed aluminum frame for a rotating squirrel cage to form magnetoelectrodynamic rotational torque. Motors are divided into DC motor and AC motor according to the power supply. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (motor stator magnetic field speed and rotor rotation speed do not keep synchronous speed). The motor is mainly composed of stator and rotor. The direction of force movement of the current conductor in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (the direction of the magnetic field). The working principle of the motor is the effect of the magnetic field on the current force, so that the motor rotates.Sensor Door

2. Controller:

The controller is composed of logic controller and microprogram controller. The two kinds of controller have their own advantages and disadvantages.

Controller model

Combinatorial logic controller is cumbersome in design and complex in structure. Once the design is complete, it cannot be modified or expanded, but it is fast. Microprogram controller is convenient in design, simple in structure, easy to modify or expand, modify the function of a machine instruction, only need to reprogram the corresponding microprogram; To add a machine instruction, just add a microprogram to the control memory, but it does so by executing a microprogram. The specific comparison is as follows: combinational logic controller, also known as hardwired controller, is composed of logic circuit, completely rely on hardware to achieve the function of instructions.

3. Pulley:

A pulley is a small wheel with slots around it that rotates around an axis. A simple machine that rotates about a central axis is called a pulley, consisting of a grooved disc that rotates about a central axis and a flexible cord (rope, tape, steel cable, chain, etc.) that crosses the disc.Automatic door

4. Belt:

Tape for transmitting mechanical power, including flat drive tape and triangle drive tape (V-shaped tape). Made of rubber and reinforced materials such as cotton canvas, rayon, synthetic fibers or steel wire.

Made of multi-layer hanging canvas, synthetic fiber fabric, cord and steel wire as tensile layer, coated with rubber after forming, vulcanizing.

Compared with gear drive and chain drive, belt drive has the advantages of simple mechanism, low noise and low equipment cost, and is widely used in a variety of mechanical power transmission.

The ring belt driven by the machine is set on two belt wheels. It is made of cowhide or wire rubber. It is also called belt.
