An elevator intelligent call system and method based on near field communication

Abstract

The invention relates to an intelligent elevator calling system based on NFC and a calling method implemented through the system. The method includes the steps that firstly, user registration is carried out, an elevator use request is submitted to an elevator administration department, and a corresponding certificate file is generated after real name verification is carried out; secondly, an elevator calling control module generates an elevator calling request according to a target floor of a user and sends the elevator calling request to an elevator calling device on a current floor elevator waiting position through a first NFC module; and thirdly, a second NFC module of the elevator calling device receives the elevator calling request which is verified through a permission verification module; if the verification of the request succeeds, the elevator calling request is sent to an elevator dispatching control module to make a response; and if the verification of the request fails, request failure information is sent to the elevator calling control module. A mobile device with the NFC function is used for sending the elevator calling request conveniently and quickly; information of the target floor and the weight of the user is provided, and elevator dispatching efficiency is improved; and an adopted mobile device certificate verification mechanism is simple, quick and safe.

Description

technical field [0001] The present invention relates to an elevator intelligent calling system and method, in particular to an elevator intelligent calling system and method based on NFC (Near Field Communication, near field communication). Background technique [0002] With the development of economy and technology, more and more high-rise buildings have sprung up. In these high-rise buildings, elevators are indispensable, and usually a plurality of elevators are set up to run simultaneously in a building. Since traditional elevators only have two buttons for up and down on each floor, it is impossible to determine the number of people waiting on each floor and the corresponding load. The dispatching method is often that a certain elevator responds to the external call request of each floor, so During the peak period, there will be an unreasonable scheduling phenomenon that many elevators that are not fully loaded pass a certain floor in the same direction, and only one el...

Problems solved by technology

[0006] However, the various scheduling schemes currently used above all have different shortcomings and limitations

Among them, the traditional elevator group control algorithm is based on simulation to obtain the optimal scheduling scheme, which requires a lot of calculations, increases the cost of software and hardware, and the obtained scheduling scheme is uncertain

However, the group control algorithm based on the guidance of the destination floor needs to set up input devices including all floors on each floor. When there are many floors, the cost will be greatly increased.

As for users who have to carry IC cards to take the elevator, it is very inconvenient, and the IC card has the risk of being illegally copied; and this method also needs to store user information in the elevator system, so that when the number of users increases sharply, the elevator system needs to add additional At the same time, each elevator system needs to store user data, resulting in data duplication and a great waste of resources

In addition, the method of querying user authority information from a specified interface needs to connect the elevator system to the network server, which increases the complexity of the elevator system design, and once the connection with the server fails, the elevator cannot be used normally
