Description
Technical field
The present invention relates to technical fields such as sensor technology, elevator automatic guidance, specifically, relate to a kind of apparatus for controlling elevator and method based on infrared detector.
Background technology
Care to consumer psychology and emotion is the imbody to human nature care, also is the sure and perfect of " people-oriented " design concept, is the indispensable aspect of current product design.
Traditional its working mechanism of elevator lifting system is following:
1. the passenger according to the needs of own upstream or downstream, by last direction or lower direction arrow button, sends calling signal at using escalator floor elevator entrance place, waits for that elevator arrives.
2. elevator device obtains calling signal and notes, and when running to called floor, elevator opens the door, and personnel walk out elevator in the car, and the passenger who calls out elevator then gets into lift car.
3. after the passenger got into car, the floor that arrives was as required pressed corresponding digital button on the interior control wheel of car, as long as this Push-button lamp is bright, the choosing layer that the passenger then is described is by record.
4. elevator can open the door after running to passenger's bed of interest automatically, and the passenger walks out elevator in order and accomplishes the using escalator process.
5. elevator continues operation according to call record and choosing layer record.
Yet; We often run into such situation in daily life: after the passenger presses the using escalator button; Because a variety of causes (such as emergency situations) left again, like this, elevator is parked in this floor according to call record and when opening the door; Do not have the passenger will take elevator, promptly elevator has carried out once the skimble-skamble ladder action of opening the door that stops at all.This present situation, brought following problem:
(1) the elevator transport efficiency reduces.
When elevator is parked in the floor that the passenger left; " action " that this of elevator stops is to flog a dead horse in fact, and with respect to the lifting time of whole elevator, this process of stopping is long; From this angle, the transport efficiency of elevator reduces greatly.
(2) delay time of people.
In the epoch of this high-speed operation, the time is exactly chance, and the time is exactly wealth.When elevator is parked in the floor that the passenger left, delayed the quality time of taking the people of elevator.
(3) influence people's mood
It was exactly more uninteresting waiting for bus, take a lift etc. originally; More boring; In this process, run into does not just have the situation that the passenger need take elevator after stop the elevator centre at all, can let the people feel bad undoubtedly, and this potential negative feeling can have influence on the ensuing work of people or other activities.
