Description

Elevator system which is controlled through the Internet and a method

The present invention relates to an elevator control panel computer using the Internet technology and the related technology of the elevator employing the same.

1 is a block diagram of a general elevator system.

Common elevators include machine rooms, cars, platforms, hoists, control panels, and the like.

The elevator control system consists of several subsystems.

Conventional elevator system is composed of a group management system 110 for managing the operation of a plurality of elevators, each of the management system for managing each elevator (111, 112, .......), these are a military management system Networked with 110 is controlled.

There are four types of elevator construction networks.

The first network is a platform that connects the platform-based microcomputer and platform devices to the platform-based network 101 to control buttons, indicators, and doors.

The second network is a network that connects the microcomputer and platform equipment of each platform management to the platform-based network 102 to control a platform button or a platform indicator.

The third network is a military management series network 103 to provide military management information by connecting to each unit management microcomputer.

The fourth network is an option-based network 104 that connects the microcomputer of each unit management and the optional equipment to control hall information and waiting time indicators.

The general idea of the Internet is a network based on the TCP / IP protocol and a large network of networks. There is a lot of information stored on the Internet, and when you use the Internet, you can get the information you want in real time without the constraints of time or space.

A protocol is a communication method agreed upon with each other and is generally interpreted as a communication protocol. Which computer will initiate communication in the exchange of data between computers, and how to respond to the communication. How to express the data, how to handle errors that occur during communication, etc., and the countermeasures are required according to the case, and this role is called a protocol.

Each network has a language that each member computer can communicate with, and it is as diverse as the language of the world, so even if it is connected to an external network, it cannot communicate with each other if the protocol is wrong. Thus, the emergence of the standard TCP / IP protocol has been the driving force behind the development of the Internet.

The Internet can provide services such as web, e-mail, file transfer, chat, news, telnet, gopher, etc. In particular, the web service is the most widely used and is now representing the concept of the Internet.

Conventional elevator control method is divided into the microcomputer for the control of each unit management system (111, 112, ...) of each elevator and the microcomputer of the military management system 110 to manage them collectively, unilaterally of the military management system (110) Control is mainstream.

In other words, it can be said to be controlled under extreme server / client environment. This has a problem that the incorrect operation or error of the server system can seriously affect the control of each elevator system.

In addition, the conventional elevator is a general function to provide only the floor change information to the transport function.

The use of billboards or TVs in these elevators has provided a more advanced form of providing simple information or advertisements.

However, these elevators have many management problems. In other words, it is a problem to directly control the machine mounted on the elevator and a problem that the quickness is poor in the rapid data update.

In addition, the one-sided information transfer is mainly focused on the information provided rather than the relationship with the user. Information delivery in this way is limited in its true meaning.

In addition, the quality of information provided is less easy to update or process data, which is more problematic than other information providing media, and due to the specificity of the space of elevators, there is a significant loss in the recognition and recognition rate of the provided information.

The technical problem of the present invention is to solve the above disadvantages, and to improve the performance and efficiency of the elevator control panel by employing the first advanced computing model. It is to make the elevator control computer model into a simple and efficient organization through the interactive internet computing model rather than the simple batch control computing.

Secondly, various information can be provided in the space called elevator. In other words, it provides various forms of information, not just floor information and waiting time information, and utilizes the Internet as a medium for providing information to implement a system that interacts with elevator users rather than unilateral information delivery.

The Internet service unit 503 processes and provides information on the Internet and the intranet with an elevator control computer, and performs processing related to user key input.

The detailed configuration of the operation control unit 501 software is shown in FIG.

Referring to FIG. 6, the driving control unit 501 includes a driving information collecting unit 601 for collecting driving information of its own elevator or another elevator and a driving information processing unit 602 for processing the collected information.

The operation flow of this software is shown in Fig. 7, and its operation is as follows.

First, the service information collecting unit 601 waits for the service information to arrive (S701), and analyzes the type of information when the service information arrives (S702).

If the analyzed information is elevator driving information, the driving information processing unit 602 generates an RS232C signal (S704) to control the elevator control unit 309, and if it is data to be displayed on the liquid crystal display device 308, in HTML form. After the encoding operation is performed (S708), the data is displayed on the liquid crystal display 308 (S709).

In addition, the operation information processing unit 602 transmits the RS232C signal as the operation information via the elevator control network 202 of the other various management systems 212,... (S705).

If an error occurs, the driving information processing unit 602 generates an error signal (S707), converts it into an HTML signal (S708), and sends a signal to the transportation information processing unit 502 and the elevator control unit 309. (S709) )

8 is a configuration diagram of the transportation information processing unit 502.

Referring to FIG. 8, the transportation information processing unit 502 includes a transportation information analysis unit 801 for taking and analyzing driving information and hall information, and an information decoding unit 802 for processing the image information on the LCD monitor.

Next, the operation of the transportation information processing unit will be described with reference to FIG.

First, the transport information analyzer 801 determines whether the transport information has arrived (S901), and if the transport information has arrived, analyzes the type of transport information (S902).

Then, the information decoding unit 802 decodes the information according to the type (S903) and outputs the processed information to the liquid crystal display device 308 (S904).

On the other hand, the transportation information analysis unit 801 generates an abnormal signal when a fatal error for the elevator occurs (S905) (S906), stops the operation of the elevator by controlling the elevator control unit 309, there may be an operator action The operation is suspended until (S907).
