Accordingly, each user should possess all devices such as a monitor, a main frame, a mouse, a keyboard, etc., so that it costs a lot in order for a plurality of users to independently use computers. In particular, it is not effective to possess as many computers whose programs' difficulty or frequency of use is fixed, in places where a plurality of people come and go (such as front offices of stock markets, pharmacies, reading rooms in libraries and hospitals), as the number of users. As development of computer hardware and software progresses in very high speed, it is natural that better hardware and software come out just a few months after purchasing a computer. Thus, it requires a great expense to upgrade computer devices according to high speed of development. Further, network devices are needed in a case where a network is to be constructed to share data among users, so that it has been an economical burden for users.

Further, there is too much spatial limitation to set up various devices when many users in limited space intend to use computers. To solve these problems, many computer manufacturing company have provided market with slim type computers that does not occupy much space, however, the slim type computers are also expensive to be widely distributed.

Accordingly, development of a multi-user support system, which solves the above-described economical and spatial limitations and satisfies desires of many users, is needed. If it is made possible for many users to use computers only with one computer main frame and a plurality of input/output devices, considerably positive effects will be obtained not only in expense but also in utilizing work space.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a detailed explanation will be given with reference to the attached drawings as to a multi-user support system according to the present invention. Figure 1 illustrates a multi-user support system using one computer main frame according to the present invention in a host computer connected to a plurality of stations.

The multi-user support system 1 according to the present invention is in a host computer 2 and the plurality of stations 3 connected to the host computer 2 are supported by the multi-user support system 1 of the present invention, which enables many users to independently use computers.

For connecting the plurality of stations 3 to the host computer 2 equipped with the multi-user support system 1 of the present invention, the plurality of stations 3 are connected to the host computer 2 by appropriate connecting means such as USB ports.

Desirable conditions for operating the multi-user support system 1 are a

CPU having processing speed over Pentium HI 500MHz, a RAM having memory capacity over 128MB, a hard disk having storage capacity over 20GB, a computer main frame equipped with more than 3 PCI slots and more than one USB port, stations equipped with an USB type keyboard and a mouse, and operating system such as Windows 2000 Professional or Windows 2000 Server.

The operating system such as the Windows 2000 can regulate authorities of users corresponding to own account such as an administrator account and an user account. Because only administrator account can modify operating system files, establish system service and perform all functions supported by operating system, it is made possible for a plurality of users to independently use computers using one host computer, equipped with the multi-user support system, having the administrator account. Figure 2 illustrates inner configuration of a multi-user support system using one computer main frame according to the present invention.

A multi-user support system using one computer main frame according to the present invention includes: a multi-user support system server 11; an account management module 12; a status management module 13; an input/output management module 14; and a storage device management module 15. The multi-user support system server 11 controls the account management module 12 to manage accounts (for example, to give accounts to each station connected to a host computer, to give new account to a station newly connected to the host computer, etc.). The accounts given to each station connected to the host computer are user accounts and administrator account is not given to each station.

Also, the multi-user support system server 11 controls the status management module 13 to check status of connections among each station and the host computer and to check whether there is a station newly connected to the host computer. As a result, if a station is newly connected to the host computer or a station is disconnected from the host computer, the status management module 13 detects the connection or disconnection and informs the multi-user support system server 11 of the connection or the disconnection in the real time.

The multi-user support system server 11 informed of the connection and the disconnection by the status management module 13, informs the account management module 12 of the connection and disconnection and commands the account management module 12 to give a new station new account or to delete given account. Due to this, the multi-user support system according to the present invention can easily disconnect or connect a station.

Also, the multi-user support system server 11 controls the input/output management module 14 to manage processing sequence to smoothly perform tasks inputting information from each station or outputting information to each station, without crash. The functions of the input/output management module can be easily implemented through operating systems supporting multi-task operations such as Windows 2000. Also, the multi-user support system server 11 controls the storage device management module 15 to store information inputted from each station in a storage device of the host computer and to output the information from the storage device of the host computer to the corresponding station when an output of the information is commanded. The account management module 12, the status management module 13, the input/output management module 14 and the storage device management module 15 are connected to the multi-user support system server 11 with a signal system, so that they receive commands from the multi-user support system server 11 and function for the multi-user support system in response to the commands. Figure 3 illustrates a preferred embodiment of device configuration of a multi-user support system using one computer main frame according to the present invention.

A host computer 21 includes a monitor, a main frame and a keyboard as with general computers. Each station 22, 23, 24 not equipped with a main frame is connected to the host computer 21. A station 2 (23) and a station 3 (24) are connected to the host computer 21 by USB hub 25.

A mouse and a keyboard of a station 1 (22) are directly connected to USB ports mounted on front part of the host computer's main frame. This reflects a trend that USB ports are mounted on front part of a main frame or on a monitor. The number of stations in device configuration equipped with a multi-user support system according to the present invention illustrated in Figure 3 is just illustrative, for convenience of explanation. More than three stations can be connected to the host computer.

Figure 4 illustrates an USB hub illustrated in Figure 3 in detail. Because general computer has two USB ports, USB hub 25 illustrated in Figure 4 is needed to have more than two USB ports. The USB hub 25 has four USB ports 26, 27, 28, 29, so that it has four inputs from outside. A keyboard and a mouse of station 2 (23) are connected to the USB ports 26, 27 and a keyboard and mouse of station 3 (24) are connected to the USB ports 28, 29. It is general that USB hub can have additional connections up to 127 because the USB hub can have a number of USB ports. To increase the number of users supported by the multi-user support system, USB hub having as many USB ports as the number of users can be used.

In a case where USB port is mounted on a keyboard, the number of USB ports, that the USB hub should include, decreases. In other words, as illustrated in Figure 3, in a case where three stations are used and keyboards of stations 2 (23) and station 3 (24) have USB ports, the station 2 and the station 3 can be supported by connecting each mouse of the station 2 and the station 3 to each keyboard thereof. It is possible to add a new station (for example, station 4) without new USB hub by using two USB ports among four USB ports of the USB hub 25.

Figure 5 illustrates that different screens are displayed by a multi-user support system using one computer main frame according to the present invention. It is illustrated through each monitor that different tasks are independently performed at host computer and each station. A monitor of the host computer 31 displays analysis of stock prices of this month, however, monitors of stations 32, 33 display respectively a document being edited and a car. As described above, many users can independently use computers by using one computer main frame according to multi-user support system of the present invention. This is because just 10 percent to 20 percent of performance of CPU in a main frame is used when word processing or using internet. Further, there is no probability of decrease of processing speed due to operations of a plurality of stations.

Figure 6 illustrates a screen displaying device configuration of a multi-user support system using one computer main frame according to the present invention. Figure 6 illustrates a resource manager window implemented by a multiuser support system using one computer main frame according to the present invention. The resource manager window shows that four stations are connected to a host computer. By providing information on video card, keyboard, mouse, audio card, etc. of the host computer and each station through the resource manager window, it is possible to manage the host computer and the stations.

INDUSTRIAL APPLICABILITY

According to a multi-user support system using one computer main frame of the present invention, it is possible for many users to use computers using one computer main frame, so that the users can cut down on purchasing expense of hardware and software comparing with a case where the users purchase own computers, and it is possible to cut down on upgrade expense.

Further, a multi-user support system using one computer main frame of the present invention just needs input/output devices such as a monitor and a keyboard without an extra main frame, so that work space can be minimized, comparing with a case where the extra main frame is used, to overcome spatial limitation and to increase work efficiency.

Further, a multi-user support system using one computer main frame of the present invention can response in the real time when disconnection of stations and connection of a new station happens, so that it is comfortable to remove or add stations.
