The working principle of induction door door sensors and different price
First, the principle of induction door
Induction door is mainly refers to the door switch of a control system by way of induction to complete another category of the door switch, and according to the induction of different can also be divided into microwave induction door, touch induction type door and infrared ray induction door, credit card induction door and so on.
Unit constitution:
Main controller: it is commander in chief of the automatic door, through the internal has set good program of large-scale integrated block, sends out the corresponding instruction refers to guide motor or electric lock system work.
Induction detector: responsible for the collection of external signals, as people's eyes, when you see a moving object into its control range, it gives the main controller a pulse signal.
Motor power: it is mainly open the door and provide the initiative, door control acceleration and deceleration operation.
Door track: like the train fixed rail, sling control door wheel system, make it in a particular direction.
The doors sling go round system: used for hanging door activities, while in power traction drive door leaf operation.
Synchronous belt transmission for motor power, traction doors sling go round system.
The lower part of the guidance system is the guiding and positioning device to prevent the lower part of the door leaf, the door body door before and after the emergence of swing at run time.
Workflow: induction induction detectors to to close to people or objects, will pulse signal to convey to the main controller, and the main controlling device by the judge after notice of motor running. At the same time, the monitoring motor speed, to inform the motor in particular when afterburning and enter slow operation. After running a certain current motor do run forward, the dynamic force is transmitted to a synchronous belt, again by the synchronous belt to transmit the power to the spreader system to open the door and window; leaf after opening by the controller to judge, usually in within a certain period of time (time by the place of the decision, set by the administrator) if in the middle of the door no moving objects, the induction detector will to main controller issued a closing signal. So, on the completion of the open closed. (as shown in the figure below)
Two, the introduction of price
Price: different brand price is slightly different, as the joint venture brand price is 8000 yuan price interval, such as: Antonin Lai, Panasonic, etc. And the import brand price is higher than the joint venture brand, about 8000-15000 yuan price range, such as: Rui up, STANLEY and other well-known brands.
Door body price: door and construction costs are usually based on the size of the entrance of the store to calculate the size of (the size of the unit price per square meter). And the specific price is divided into a box door, no box full glass door. A box door body at a price of 600-900 yuan / square meter, no box door body unit price of 500-750 yuan / square meter. Because each level of technology and construction materials quality is not the same, so the price is appropriate will difference (the door to find the best warranty of two years of, because if it is a two-year warranty, that its technological level is quite good) |
