Abstract

The utility model belongs to a connector for connecting a computer input device to a computer, which is organically formed by a device interface unit [1], a control unit [2], and a computer interface [3]. The device interface unit comprises two or more than two device interfaces [11] which can be connected with the existing computer input devices, and the computer interface [3] can be connected with the computer. The usage of a plurality of congener computer input devices on the same computer can be realized by using the utility model. Therefore, exchange of the congener computer input devices is not needed when one computer is used by a plurality of people, which causes convenient operation.

Description

A kind of computer entry device connector

The utility model belongs to the connector of a kind of computer entry device to computing machine.Specifically be the connectors of a plurality of similar computer entry devices to computing machine.The computer entry device here refers in particular to the computer entry device that is used for man-machine interaction and carries out communication with serial mode with computing machine; Here similar is meant that the purposes definition identical, main signal of computer entry device is identical.

Present computing machine can only use a mouse or a computer entry device such as keyboard, the problem of its existence is: when many people use a computing machine, when instructing child to learn on computers such as father and mother, two people are when recreation is played chess in object for appreciation or the like, because that computer entry devices such as frequent exchange mouse or keyboard between many people have caused is inconvenient and inefficient.

The purpose of this utility model will address the above problem exactly, and the connector of a kind of computer entry device to computing machine is provided.Use the occasion of a computing machine many people, the utility model can make a plurality of similar computer entry device co-ordinations, but everyone equal operational computations machine like this, and need not to exchange this class computer entry device.

The purpose of this utility model realizes by the following technical solutions:

Characteristics of the present utility model are: by facility interface unit, and control module, the organic formation of computer interface.Wherein facility interface unit comprises several (two or more) equipment interfaces, and this interface is wired socket mode or is wireless mode, can be connected with the active computer input equipment; Computer interface can be connected with computing machine.The signal end of each input equipment interface links to each other with control module by the corresponding signal line, and the signal end of computer interface unit links to each other with control module by corresponding signal lines.The course of work of this connector is: control module detects signal from each similar computer entry device by facility interface unit and corresponding signal line on the basis of finishing with the basic function of computer entry device corresponding calculated machine controller, control module selects the signal of certain computer entry device to make it deliver to computer interface by the signal wire that links to each other with computer interface according to certain arbitration principle then, finally sends in the computing machine.

From technique scheme as can be seen, the utility model can be implemented in and use a plurality of similar computer entry devices on same the computing machine, uses the occasion of a computing machine like this many people, need not to exchange this class computer entry device, make easy to operately, improved efficient.

Accompanying drawing of the present utility model is:

Accompanying drawing 1 is the structure principle chart of this connector;

Accompanying drawing 2 is circuit theory diagrams of this connector.

The figure number explanation:

Facility interface unit [1] equipment interface [11]

Control module [2] computer interface [3]

Signal wire (to equipment interface) [4]

Signal wire (to computer interface) [5]

An embodiment of the present utility model is: input equipment interface [11] adopts the socket of PS/2 type, has two here; Control module [2] is that core constitutes by microprocessor AT89C2051; Computer interface [3] adopts the plug of PS/2 type.DATA, CLK in each input equipment interface [11] end links to each other with the I/O mouth (P1.4-P1.7) of AT89C2051 in the control module [2] by signal wire [4], and the I/O mouth (INT0, INT1) of AT89C2051 passes through signal wire [5] and holds with DATA, CLK in the computer interface [3] and link to each other in the control module [2].The course of work of this connector is: control module [2] is by DATA, the CLK signal of facility interface unit [1] and signal wire [4] detection from each similar computer entry device, control module [2] selects the signal of certain computer entry device that it is held by DATA, CLK that I/O (INT0, INT1) delivers to computer interface [3] by signal wire [5] according to certain arbitration principle then, finally sends in the computing machine; The arbitration principle can be (establishing the signal that A, B represent two similar computer entry devices respectively): under A, B equal conditions, select A; If a-signal changes from weak to strong and the B no signal, then select A, vice versa; If the a-signal continued presence, then no matter how the signal of B selects A, vice versa.By the description of embodiment as can be known this connector can coordinate the common use of a plurality of similar computer entry devices, use the occasion of a computing machine like this many people, make easy to operate, efficient improve.
