The utility model discloses be applied to the technical field of the full key conflict-free keyboard of bluetooth.
Description
Technical Field
The utility model relates to a full key does not have conflict keyboard, in particular to bluetooth full key does not have conflict keyboard.
Background
Because the bluetooth uses a 2.4G public frequency band, signals such as WIFI and zigbee also exist on the frequency band, and the coverage rate of the WIFI signal is high, and the interference to the bluetooth signal is large, the data sent by the keyboard using bluetooth communication is not good in the use experience of entertainment games and the like due to serious delay. Currently, bluetooth technology, which is most used by bluetooth keyboards, is bluetooth3.0, and the delay of the technology is relatively serious and the data transmission amount is relatively small. The existing Bluetooth keyboard is basically used for common office work, naturally, the requirement on the full key without conflict is less, and other manufacturers do not develop the full key function without conflict. In addition, as the standard protocol of the HID keyboard is six-key no-rush, if the keyboard is always full-key no-rush, the compatibility problem exists because some systems cannot identify the keyboard.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a bluetooth full key does not have confliction keyboard, bluetooth full key does not have confliction keyboard can avoid the unable discernment keyboard of system and lead to unable the use, can realize again that the full key does not have the function towards when having needs.
The utility model adopts the technical proposal that: the utility model discloses a keyboard control unit, bluetooth data transceiver unit, button scanning unit, power and battery management unit, data storage unit, bluetooth data transceiver unit, button scanning unit, power and battery management unit and data storage unit all with the keyboard control unit is connected, bluetooth full key does not have conflict keyboard still include with the keyboard control unit connected keyboard data mode switching unit; the switching mode of the keyboard data mode switching unit is that the standard data packet mode is switched to the non-standard data packet mode, or the non-standard data packet mode is switched to the standard data packet mode.
Further, the standard packet mode corresponds to a 6-key collision-free mode, and the non-standard packet mode corresponds to a full-key collision-free mode.
Furthermore, the Bluetooth full-key conflict-free keyboard further comprises a Bluetooth channel switching unit connected with the keyboard control unit.
Further, the bluetooth data transceiver unit is a data transceiver unit based on bluetooth 5.0 technology. The Bluetooth technology is Bluetooth 5.0, so that the data sending quantity is large and the speed is high.
The utility model has the advantages that: because the utility model adopts the design of automatic switching between the two modes of 6-key no-impact and full-key no-impact, when the number of the pressed key is less than or equal to 6 keys, the 6-key no-impact mode is used; automatic switch to full key conflict-free mode when the key number of pressing is greater than 6 keys, can easily get into the system like this, effectively improve the transmission rate and the accuracy of data, the utility model provides a bluetooth full key conflict-free keyboard has solved when using bluetooth keyboard, has some to have to dash to have the operation that requires to have restriction and unpleasant experience to the full key. With the progress of the bluetooth technology, the data transmission speed of the bluetooth 5.0 technology has become significantly faster, and the transmitted data volume is larger, and the anti-interference processing is performed on hardware, so that the keyboard using the bluetooth 5.0 technology can meet the use requirements of fields such as entertainment games and the like with higher requirements on key response delay. Therefore, the Bluetooth full-key conflict-free function is provided, and better experience requirements on use of entertainment games and the like are met.
In order to meet the use requirements of multiple devices at the same time, the Bluetooth conflict-free keyboard can be connected with the multiple devices at the same time, and rapid switching input can be carried out among different devices through keys. The requirements of entertainment and office work at the same time are met.

Fig. 1 is a structural view of the present invention.
Detailed Description
As shown in fig. 1, in this embodiment, the present invention includes a keyboard control unit 1, a bluetooth data transceiver unit 2, a key scanning unit 3, a power and battery management unit 4, and a data storage unit 5, wherein the bluetooth data transceiver unit 2, the key scanning unit 3, the power and battery management unit 4, and the data storage unit 5 are all connected to the keyboard control unit 1, and the bluetooth full-key conflict-free keyboard further includes a keyboard data mode switching unit 6 connected to the keyboard control unit 1; the switching mode of the keyboard data mode switching unit 6 is to switch the standard data packet mode to the non-standard data packet mode, or to switch the non-standard data packet mode to the standard data packet mode. There is a compatibility problem because the full key collision free packet is not a standard packet model. So we adopt the automatic switching of the two modes of 6-key no-rush and full-key no-rush. When the number of the pressed key is less than or equal to 6 keys, a 6-key dash-free mode is used; and when the number of pressed keys is more than 6, automatically switching to a full-key conflict-free mode.
In this embodiment, the standard packet mode corresponds to a 6-key collision-free mode, and the non-standard packet mode corresponds to a full-key collision-free mode.
In this embodiment, in order to simultaneously satisfy the current requirements of multiple devices, the bluetooth full-key conflict-free keyboard further includes a bluetooth channel switching unit 7 connected to the keyboard control unit 1, and the bluetooth conflict-free keyboard can be connected to 5 devices simultaneously, and can perform fast switching input among different devices through keys, thereby satisfying the requirements of simultaneous entertainment and office.
The bluetooth data transceiver unit 2 is a data transceiver unit based on bluetooth 5.0 technology. The Bluetooth technology is Bluetooth 5.0, so that the data sending quantity is large and the speed is high.
The working method of the Bluetooth full-key conflict-free keyboard comprises the following steps:
a. the key scanning unit 3 scans the keyboard, when the number of the pressed keys is less than or equal to 6 keys, the keyboard data mode switching unit 6 is in a standard data packet mode, a 6-key non-impact mode is used, the keyboard control unit 1 controls the Bluetooth data transceiving unit 2 to send out a 6-key non-impact standard data packet, and the transmission speed and the accuracy of data can be effectively improved;
b. the key scanning unit 3 scans the keyboard, when the number of pressed keys is more than 6, the keyboard data mode switching unit 6 automatically switches from a standard data packet mode to a full-key collision-free mode, and the keyboard control unit 1 controls the bluetooth data transceiving unit 2 to send out a full-key collision-free standard data packet.
In this embodiment, the full-key dash-free standard data packet is a 14-byte data packet, each data bit represents one key, and 14 bytes can represent 112 keys in total, that is, when all keys of the keyboard are pressed simultaneously, all pressed keys can be sent out through one data packet, so that the data sending amount is reduced to the maximum extent. The following is a full key collision-free data packet key mapping position table, where bit0 of the first byte of the data packet is position 1, bit7 is position 8, bit0 of the second byte is position 9, and so on:
while the embodiments of the present invention have been described in terms of practical embodiments, they are not intended to limit the scope of the invention, and modifications of the embodiments and combinations with other embodiments will be apparent to those skilled in the art in light of the present description.
