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.

An input end of said registration unit 2 is connected to said resistance unit 1 and said pull down resistor R
dBetween, be used to gather said pull down resistor R
dInput voltage, and, confirm the calling information of user to elevator according to the magnitude of voltage that collects; In a preferred embodiment, said registration unit 2 specifically is used to gather said input voltage, and magnitude of voltage that collects and preset voltage threshold are carried out matching judgment, confirms said calling information;
In the electricity voltage divider principle; For a given power supply, the voltage that the resistance of different resistances can be assigned in the series connected resistance has nothing in common with each other, through the action of switch; Can carry out short circuit (open type button) or open circuit (closed type button) to the pairing resistance of this switch; Thereby form different resistance combinations, a collection point is set in circuit, can assign to different voltages according to different switch motions;
The present invention has utilized above-mentioned electricity voltage divider principle dexterously; Each resistance and button switch in the resistance unit 1; (this calling information for calling in the elevator sedan-chair, comprises the floor calling operation of pressing on the calling panel of user in car to respective user to each calling information of elevator; For the elevator outer-office calling, call together on comprising then that the user of each floor presses or under the calling operation); Through the open and close action of each button switch, the resistance of resistance unit 1 has different variations, and the voltage that pull down resistor Rd assigns to also has nothing in common with each other; Therefore the voltage assigned to of real-time judge pull down resistor Rd then can be confirmed the calling information of user to elevator;
As shown in fig. 1; In the present embodiment; Said registration unit 2 can be upper computer, and an input end of said upper computer is connected between said resistance unit 1 and the said pull down resistor Rd, is used to gather voltage; And magnitude of voltage that collects and preset voltage threshold carried out matching judgment, confirm said calling information; Registration unit 2 adopts upper computer, can write down preset voltage threshold, confirms said calling information fast;
Upper computer for the numeral input; Need to insert said A and D converter 4; Convert the voltage signal that collects into digital voltage value and redispatch, so elevator calling registration system of the present invention also can comprise A and D converter 4, in the present embodiment to upper computer; It is the A/D converter 4 among Fig. 1; An input end of said upper computer is connected between said resistance unit and the said pull down resistor Rd through said A and D converter 4, and said A/D converter 4 is used to gather voltage, and converts voltage signal into digital voltage value and send to said upper computer; Upper computer carries out matching judgment with digital voltage value that receives and preset voltage threshold, confirms said calling information;
In a preferred embodiment, in the said resistance unit 1, the resistance sum of two or more said resistance is not equal to the resistance of another said resistance arbitrarily; If the resistance that inserts in the system is too much, the resistance sum that a plurality of resistance then might occur equals the situation of another resistance, and registration unit 2 just can't accurately be confirmed calling information;
Further specify the present invention through a specific embodiment below;
As shown in Figure 1, in the present embodiment elevator calling registration system of the present invention is applied to calling registration in the sedan-chair, resistance unit 1 has comprised 3 resistance R 1, R2, R3; The floor in corresponding the 1st ~ 3 building calling information respectively, 3 resistance are connected in series mutually, each resistance button switch that all is connected in parallel; 3 button switch S1, S2, S3 shown in figure, the call button in the present embodiment is selected for use (normally closed is in like manner) open in usual, establishes power supply 3 and is DC48V; Upper computer is the numeral input; Then need dispose A/D converter 4, the collection point is arranged between resistance unit 1 and the pull down resistor Rd, is used to gather the voltage that is assigned to pull down resistor Rd;
Defer to above-mentioned resistance principle; Select the corresponding resistance R 1 of ground floor call button for use, the R1 resistance is 20k Ω, the corresponding resistance R 2 of second layer call button; The R2 resistance is 30k Ω; The corresponding resistance R 3 of the 3rd layer of call button, the R3 resistance is 40k Ω, satisfies R1 ≠ R2 ≠ R3 and (R1+R2) ≠ R3, (R1+R3) ≠ R2, (R2+R3) ≠ R1 visible this moment.Pull down resistor R is set again
d, R
dResistance is 10k Ω, then can try to achieve the voltage of sampling point through following formula, promptly assigns to the voltage U of pull down resistor in the circuit
Out,
Consider the resistance error and the measured error that in actual engineering, exist, it is accurate to cause system outlet voltage to lose, and for avoiding upper computer to the registration of calling information mistake, can suitably relax the voltage value of detecting; General resistance has 5% ~ 10% deviation, and like following table, in positive negative bias 5% scope, all can confirm should calling information;
The figure place of the A/D converter 4 in the present embodiment is 12, establishes 0FFF and representes 18V, and A/D output U is then arranged
DigiFor:
