Description
Technical field
The present invention relates to elevator calling register technique field, particularly relate to a kind of elevator calling registration system, and a kind of elevator.
Background technology
In the elevator industry, the calling registration system mainly contains two kinds at present:
1, serial communication calling registration system:
This type systematic needs a serial communication electron plate; The input port quantity of this electron plate need to equal the quantity of call button; Each button inserts corresponding I/O interface on the electron plate through order wire, and when button is pressed, electron plate detects on-off signal; With these on-off signal codings, send to upper computer through serial communication then.The shortcoming of this system is, each button needs all independently that order wire links to each other with electron plate, and takies a large amount of I/O resources, if having only 15 button I/O on this electron plate, has then restricted it and can only be used for 15 layers or lower elevator device.This calling register method is with high costs, and calling quantity is seriously restricted, and more because of wiring in addition, the Installation and Debugging complicacy is loaded down with trivial details, and fault rate is higher.
2, parallel communications calling registration system:
This type systematic needs each button wiring is applied to machine room upper computer input port from button position, place always.The same with serial communication mode is that each button need take an I/O mouth.If being used for, this calling registration system calls in the sedan-chair of elevator of layer/stand/be 20; If promoting height is 60 meters, then the call button line length needs 20 * 60=1200 rice altogether in the sedan-chair, and takies 20 I/O mouths of upper computer resource; Improved the cost of electron plate greatly; Also seriously expend wire rod, and parallel communications antijamming capability extreme difference, situation such as the wrong registration of mistake registration take place easily.In addition, have Installation and Debugging difficulty, maintaining difficulty, disadvantages such as fault rate height equally with serial communication.
To sum up, traditional elevator calling registration system exists shortcomings such as wire rod is too much, with high costs, installation complicacy.
