After refreshing key module inquiry list, key information is waited, the key of key module is reported if having key information The time for whether arriving inquiry button module is inquired after value, otherwise directly inquires the time for whether arriving inquiry button module；

If inquiring the time for having arrived inquiry button module, list is inquired according to key module, in key bus Each key module is inquired, and key information is otherwise waited for.

Figure 25 is please referred to, described to use small-sized 8 chip microcontroller from control chip, specific control process is such as Under:

After electrifying startup, the key inquiry in key bus is waited；

If there is no the key inquiry for receiving key pedestal after a period of time, background light is made to send out a warning or put out background light It goes out, otherwise waits for key bus and freely state the moment；

If having arrived the key bus free moment, statement bus contention is sent to key bus, otherwise waits for key bus Freely state the moment；

If issuing a statement bus contention successfully to key bus, race condition is exited, the free sound of key bus is otherwise waited for The bright moment；

After exiting race condition, key information is waited；

If there is key information, to key bus Trigger Bus signal, key pedestal is reminded to carry out key inquiry, otherwise etc. To key information.

Figure 26 is please referred to, the specific control process at the end PC is as follows:

Realization configures the key assignments of key module, and the standard key assignments of system standard key is issued to key pedestal, And it is issued to corresponding key module, corresponding key module saves the standard key assignments.Alternatively, key module does not save the standard Key assignments, and use non-standard key assignments, when key information occur when, key pedestal by non-standard key assignments be converted to standard key assignments and on Report the end PC.

Respectively key pedestal and key module provide firmware upgrade, and firmware pushes to key pedestal and upgraded or led to It crosses key pedestal and is forwarded to key module and upgraded.

The quantity that key module is obtained by key pedestal, then shows the key arrangement of identical quantity in software interface. When key information occurs for related key module, corresponding key will be prompted in key arrangement, such as marked bright or dynamic and become Change etc., user can click the key in interface layout and select correct key assignments.Further, cursor is obtained in key arrangement Virtual key position, after cursor dwell preset time, under send instructions to key pedestal, to light corresponding key module Background light, with inform user key-press layout in virtual key and the corresponding relationship of corresponding key module.

The specific control process of server is as follows:

The upgrade service of key pedestal and key module firmware is provided.

The upgrade service of the end PC software is provided.

It provides and saves the mapping relations that user's different key module is mapped to true key assignments.

Compared with prior art, in keyboard 100 provided by the embodiment of the utility model, one of the keyboard 100 or Multiple key modules 10 are all adsorbed in key pedestal 20, it can be achieved that the key adjustment of the keyboard 100 is more flexible.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Under the thinking of the utility model, it can also be combined between the technical characteristic in above embodiments or different embodiments, Step can be realized with random order, and there are many other variations of the different aspect of the utility model as described above, be Simplicity, they do not provide in details；Although the utility model is described in detail with reference to the foregoing embodiments, this The those of ordinary skill in field it is understood that it is still possible to modify the technical solutions described in the foregoing embodiments, Or equivalent replacement of some of the technical features；And these are modified or replaceed, and do not make the sheet of corresponding technical solution Matter departs from the scope of the technical solutions of the embodiments of the present invention.
