Description

Wireless destination floor group control elevator system

Technical Field

The invention relates to the field of elevator intelligent control systems, in particular to a wireless target floor group control elevator system.

Background

In a traditional elevator group control system, passengers wait in a messy way in an elevator waiting hall, most of the passengers are crowded in front of an arriving elevator, and the passengers are crowded into a car tightly after the elevator arrives. After entering, passengers need to difficultly select a floor on the control panel or request passengers close to the control panel to help select the floor. If a passenger wants to ascend from the bottom floor to the top floor, they go through a lengthy wait because each call by another low-floor passenger will stop the car once.

The target floor group control technology solves the problem that the target floor is uncertain before passengers enter an elevator in a calling principle. The calling hardware of the target floor group control elevator system is different from the calling hardware of the traditional system in that a floor selecting control panel is cancelled in an elevator car, and only a floor display interface is left for informing the number of floors of a current stop of a passenger in the car and the number of floors reserved and registered. The elevator hall eliminates the original simple floor display and uplink and downlink calling buttons, and is replaced by a combined key keyboard which has the function of enabling passengers to select floors needing to go outside the elevator. The destination floor selector can display the elevator number provided by the elevator control system for dispatching the elevator after the passenger is registered in the floor selection. The passenger goes to the elevator corresponding to the elevator number according to the indication to wait.

Disclosure of Invention

The invention aims to provide a wireless target floor group control elevator system to solve the problem that a passenger is uncertain in a target floor before entering an elevator, so that the elevator taking efficiency is improved.

In order to achieve the purpose, the invention provides the following technical scheme:

the embodiment of the application discloses wireless destination floor group control elevator system adopts the CAN communication mode, includes:

the smart phone is connected with the Bluetooth module, and the Bluetooth module is used as a wireless expansion tool to establish data connection with the smart phone;

the Bluetooth module is connected with the data conversion chip, and the data conversion chip converts serial port data transmitted by the Bluetooth module into CAN data;

the data conversion chip is connected with the CAN communication module, and the CAN communication module sends the converted CAN data to the elevator serial communication bus;

the CAN communication module is connected with the elevator serial communication bus;

the elevator serial communication bus is connected with the group control system;

and the group control system controls a single elevator control system, a target floor selector, a calling device and a calling display through a CAN bus.

The CAN bus is a serial communication network which effectively supports distributed control or real-time control. The CAN bus CAN be used for definitely distributing the bus to ensure that different nodes apply for bus access. Even when the bus load is severe, the access can be made with the importance of the contents. To avoid a crash due to system overload.

Preferably, the radiation range of the Bluetooth module is 10-12 meters, and passengers can use a smart phone to perform communication connection before entering the elevator and perform floor selection setting on the elevator.

The working principle of the invention is that when a passenger takes a elevator, firstly, a mobile phone and the elevator are paired through Bluetooth, after the pairing is completed, a mobile phone APP is logged in, a destination floor selection device can send data of a selectable floor, after the passenger selects the floor, a floor sending button is pressed, a registration signal is sent to the elevator, an elevator dispatching signal is fed back by an elevator group control system, software can display a dispatching elevator number to the passenger, and the passenger takes the elevator according to the dispatching elevator number. Meanwhile, the passengers can call the elevator through the elevator calling device arranged in the waiting hall of the landing, after the passengers select floors, the elevator group control system feeds back elevator dispatching signals, the elevator dispatching display displays the dispatching elevator numbers to the passengers, and the passengers take the passengers according to the dispatching elevator numbers.

Compared with the prior art, the invention has the advantages that:

1. the wireless target layer group control system combines the elevator control system with the intelligent mobile phone, so that the time of waiting for registration in line in a peak period is relieved, serial signal input is changed into parallel signal input, the registration distance is shortened in space, and the waiting time is reduced;

2. according to the wireless target floor group control system, the target floors of passengers are registered before waiting for the elevator at the landing, the system allocates the proper elevator to receive the passengers through calculation, the passengers at the same target floors can be allocated to the same elevator, and the problem that the same passenger enters different cars to cause the elevator to repeatedly run to the same floor is solved.

Drawings

In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.

Fig. 1 is a schematic view of a wireless destination group controlled elevator system according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Example 1

Referring to fig. 1, a wireless group control elevator system for a destination floor uses a CAN communication method, including:

When taking the elevator, the passenger firstly pairs the mobile phone and the elevator through the Bluetooth, and after the pairing is completed, the mobile phone APP is logged in, the floor selecting device at the destination layer can send data of an optional floor, after the passenger selects the floor, the passenger presses the floor to send a button, a registration signal is sent to the elevator, the elevator group control system feeds back an elevator dispatching signal, software can display the elevator dispatching number to the passenger, and the passenger takes the elevator according to the elevator dispatching number.

Example 2

In comparison with embodiment 1, in embodiment 2, when a passenger takes a car, the passenger calls the car through a calling device installed in a waiting hall in a landing, and after the passenger selects a floor, the elevator group control system feeds back an elevator dispatching signal, and an elevator dispatching display displays an assigned elevator number to the passenger, and the passenger takes the car according to the assigned elevator number.

The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
