Abstract
The utility model relates to a multichannel keyboard data collecting device which comprises a processor, a data bus, a PS2 interface, a PS2 interface driving chip, an RS232 interface, an RS232 interface driving chip, a common keyboard and a customized keyboard. The processor is respectively connected with the PS2 interface driving chip and the RS232 interface driving chip through the data bus, the common keyboard is connected with the PS2 interface driving chip through the PS2 interface, and the customized keyboard is connected with the RS232 interface driving chip through the RS232 interface. Compared with the prior art, the multichannel keyboard data collecting device has the advantages that double-channel keyboard data recording is achieved, operation is convenient and the like.
Description
Technical field
The utility model relates to a kind of data recording system, especially relates to a kind of hyperchannel keyboard data harvester and application thereof.
Background technology
Existing keyboard data recording system is single channel, and generally all adopts common keyboard to operate, and will have defectives such as complicated operation, very not hommization, data transmission security difference like this.
The utility model content
The purpose of this utility model is exactly to provide a kind of hyperchannel keyboard data harvester for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of hyperchannel keyboard data harvester, it is characterized in that, comprise that processor, data bus, PS2 interface, PS2 interface drive chip, RS232 interface, the driving of RS232 interface chip, common keyboard and customization keyboard, described processor drives chip and is connected with PS2 interface driving chip, RS232 interface respectively by data bus, described common keyboard drives chip by PS2 interface and PS2 interface and is connected, and described customization keyboard drives chip by RS232 interface and RS232 interface and is connected.
It is 8279 chips that described PS2 interface drives chip.
It is 8250 chips that described RS232 interface drives chip.
Compared with prior art, the utlity model has following advantage:
1, realize the admission of binary channels keyboard data, allow a set of equipment both can obtain data from general keyboard, again can be from obtaining data for the intelligent keyboard of device customizing.
2, easy to operate, general keyboard, production firm is used for commissioning device; The keyboard of customization comes controlling equipment to the user; The intelligent keyboard of customization has abundant customization function key, and the user uses as snug as a bug in a rug.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of hyperchannel keyboard data harvester, comprise that processor 1, data bus 2, PS2 interface 4, PS2 interface drive chip, RS232 interface 6, RS232 interface driving chip, common keyboard 7 and customization keyboard 8, described processor 1 drives chip and is connected with PS2 interface driving chip, RS232 interface respectively by data bus 2, described common keyboard 7 drives chip by PS2 interface 4 and PS2 interface and is connected, and described customization keyboard 8 drives chip by RS232 interface 6 and RS232 interface and is connected.
