Are many kinds of automatic door sensors, first of all, sliding automatic door set consists of the following parts: 1, main controller: it is the command center of the door automatically, through internal provide instruction program of large-scale integrated circuit has issued the directive, commanding motor/electric lock system works and people through master adjust the doors open parameters such as speed, open range. 2, sensor detectors: is responsible for the acquisition of external signal, as in people's eyes, while moving the object enters when the scope of its work, it will give the host controller as a pulse signal; 3, power motor: provide opening and closing of main power, control doors in acceleration and deceleration operation. 4, door leaf tracks: tracks like trains, bound the doors hanging wheel systems, making it in a particular direction. 5, door hanger-round system: used doors hanging activity, traction drive under the doors of power to run at the same time. 6, timing belt (some manufacturers use v-belts): used to transport motor produces power, pulling the doors hanging round. 7, the lower guidance system: is the lower part of the door leaf guiding and positioning devices, preventing doors door swings back and forth occurs during run time. When the doors to complete opening and closing, the workflow is as follows: induction detectors to detect when someone enters, pulsed signals to the master, master judge and communicated the motor running while monitoring motor speed in order to notify the motor runs at some point Gary, and access slow. Motors do after some current positive run, power passed to the timing belt, then passed from timing belt dynamic Sling system so that doors open; after the doors opened to judge by the controller, if you need to close, informed the motor reverse movement, closing the doors. Automatic door using the scope and function of automatic door suitable for hotels, hotels, banks, office buildings, hospitals, shops, etc, is widely used. Using automatic door, air conditioning energy savings, reduce noise, wind, dust-proof, and can make us of the ship out of high-grade. How to select a sensor configuration according to the installation environment of automatic doors and door requirements, selecting the configuration of automatic doors. 1) sensor choice: luxury hotels, office buildings, you can choose high-sensitivity sensors; at the edge of the sidewalk was often passing places such as banks, shops, select a narrow range of sensors. 2) safety assist device: in upscale hotels need to stamp out incidents of automatic door clips, you can choose to install anti-gripping person infrared sensor. 3) installation of access control systems and electric lock: self banks to install automatic doors, installing self-service banking access control system can be increased for the installation of electric locks, in order to realize the control access door. 4) equipped with a backup power supply: to ensure the automatic doors can work properly when power outages, can be equipped with a backup power supply.
