Problems solved by technology

If this call registration system is used for the car call of an elevator with 20 floors/stations/doors, and the hoisting height is set to 60 meters, the length of the call button line in the car needs to be 20×60=1200 meters in total, and 20 meters will be occupied by the upper computer. Each I/O port resource greatly increases the cost of the electronic board, and also consumes a lot of wire materials, and the anti-inte

Example Embodiment

[0022] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0023] The invention utilizes the principle of electrical voltage division to provide an elevator call registration system with simple structure, convenient debugging, less wires and low cost, such as figure 1 Shown is a schematic circuit diagram of the elevator call registration system of the present invention in a preferred embodiment. The elevator call registration system includes: a resistance unit 1, a registration unit 2, a power supply 3 and a pull-down resistor R d ;

[0024] One end of the resistor unit 1 is connected to the power supply 3, and the other end is connected to the pull-down resistor R d ground;

[0025] The resistance unit 1 includes two or more resistors R1-Rn and two or more push-button switches S1-Sn, each of the resistors is connected in series wit...

Abstract

The invention provides an elevator calling and registering system and an elevator. The system comprises a resistance unit, a power supply, a pull-down resistor and a registering unit; one end of the resistance unit is connected with the power supply, and the other end of the resistance unit is grounded through the pull-down resistor; the resistance unit comprises two or more resistors and button switches, all the resistors are connected with one another in series, and each resistor is connected with one button switch in parallel; each button switch corresponds to a floor, wherein the resistance value of the any one resistor does not equals to the resistance value of the other resistor; one input end of the registering unit is connected between the resistance unit and the pull-down resistor, is used for acquiring the input voltage of the pull-down resistor, and determines the elevator calling information of a user according to the acquired voltage value; and the elevator comprises at least one elevator calling and registering system. The elevator calling and registering system and the elevator have simple structures, are convenient to install and debug, use less wires and are low in cost.

Description

technical field [0001] The invention relates to the technical field of elevator call registration, in particular to an elevator call registration system and an elevator. Background technique [0002] At present, in the elevator industry, there are two main types of call registration systems: [0003] 1. Serial communication call registration system: [0004] This type of system requires a serial communication electronic board. The number of input ports of the electronic board is equal to the number of buttons to be called. Each button is connected to the corresponding I / O interface on the electronic board through a communication line. When the button is pressed, the electronic board Detect switch signals, encode these switch signals, and then send them to the host computer through serial communication. The disadvantage of this system is that each button requires an independent communication line to be connected to the electronic board, and it takes up a lot of I / O resource...
