Description

Technical Field

[0001] The present invention relates to a full-key non-conflict keyboard and a working method thereof, and in particular to a Bluetooth full-key non-conflict keyboard and a working method thereof. Background Art

[0002] Since Bluetooth uses the 2.4G public frequency band, there are also WIFI, Zigbee and other signals on this frequency band, and the coverage rate of WIFI signals is relatively high, which has a great interference with Bluetooth signals. Therefore, the data sent by the keyboard using Bluetooth communication has a serious delay, which is not good for the user experience of entertainment games. Currently, the most commonly used Bluetooth technology for Bluetooth keyboards is Bluetooth 3.0. This technology has a serious delay and the amount of data sent is relatively small. As a result, the current Bluetooth keyboards are basically used for ordinary office use, and naturally there are fewer requirements for full-key conflict-free, so no other manufacturers have developed the full-key conflict-free function. In addition, since the HID keyboard standard protocol is six-key conflict-free, if the keyboard is always full-key conflict-free, some systems will not be able to recognize the keyboard and there will be compatibility issues. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a Bluetooth full-key conflict-free keyboard and a working method thereof. The working method of the Bluetooth full-key conflict-free keyboard is simple and effective. The Bluetooth full-key conflict-free keyboard can avoid the system being unable to recognize the keyboard and causing it to be unusable, and can also realize the full-key conflict-free function when needed.

[0004] The technical solution adopted by the present invention is: the present invention includes a keyboard control unit, a Bluetooth data transceiver unit, a key scanning unit, a power supply and battery management unit, and a data storage unit. The Bluetooth data transceiver unit, the key scanning unit, the power supply and battery management unit, and the data storage unit are all connected to the keyboard control unit. The Bluetooth full-key conflict-free keyboard also includes a keyboard data mode switching unit connected to the keyboard control unit; the switching mode of the keyboard data mode switching unit is switching from a standard data packet mode to a non-standard data packet mode, or switching from a non-standard data packet mode to a standard data packet mode.

[0005] Furthermore, the standard data packet mode corresponds to the 6-key conflict-free mode, and the non-standard data packet mode corresponds to the full-key conflict-free mode.

[0006] Furthermore, the Bluetooth full-key conflict-free keyboard also includes a Bluetooth channel switching unit connected to the keyboard control unit.

[0007] Furthermore, the Bluetooth data transceiver unit is a data transceiver unit based on Bluetooth 5.0 technology. Bluetooth uses Bluetooth 5.0 technology, which has a large amount of data to be sent and a fast speed.

[0008] The working method of the Bluetooth full-key conflict-free keyboard is as follows:

[0009] a. The key scanning unit scans the keyboard. When the number of keys pressed is less than or equal to 6 keys, the keyboard data mode switching unit is in the standard data packet mode, using the 6-key no-ghost mode, and the keyboard control unit controls the Bluetooth data transceiver unit to send a 6-key no-ghost standard data packet;

[0010] b. The key scanning unit scans the keyboard. When the number of keys pressed is greater than 6, the keyboard data mode switching unit automatically switches from the standard data packet mode to the full-key conflict-free mode, and the keyboard control unit controls the Bluetooth data transceiver unit to send a full-key conflict-free standard data packet.

[0011] Furthermore, the full-key conflict-free standard data packet is a 14-byte data packet, each data bit represents a key, and 14 bytes can represent a total of 112 keys. That is, when all the keys on the keyboard are pressed at the same time, all the pressed keys can be sent out through one data packet, minimizing the amount of data sent.

[0012] The beneficial effects of the present invention are as follows: since the present invention adopts the design of automatic switching between the two modes of 6-key anti-collision and full-key anti-collision, when the number of keys pressed is less than or equal to 6 keys, the 6-key anti-collision mode is used; when the number of keys pressed is greater than 6 keys, it automatically switches to the full-key anti-collision mode, so that the system can be easily entered, and the data transmission speed and accuracy can be effectively improved. The Bluetooth full-key anti-collision keyboard proposed by the present invention solves the problem that when using a Bluetooth keyboard, there will be limitations and unpleasant experiences in some operations that require full-key anti-collision. With the advancement of Bluetooth technology, the data transmission speed of Bluetooth 5.0 technology has become significantly faster, and the amount of data sent is larger. In addition, the hardware has been processed for anti-interference, so the keyboard we use with Bluetooth 5.0 technology can already meet the use requirements of entertainment games and other fields that have relatively high requirements for key response delay. Therefore, we have proposed the function of Bluetooth full-key anti-collision to meet the requirements of better experience in the use of entertainment games.

[0013] In order to meet the needs of using multiple devices at the same time, this Bluetooth conflict-free keyboard can connect to multiple devices at the same time, and quickly switch input between different devices through buttons, meeting the needs of entertainment and office at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural diagram of the present invention;

[0015] Figure 2 It is the key mapping position table of the full-key conflict-free data packet. DETAILED DESCRIPTION

[0016] like Figure 1 and Figure 2 As shown, 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 supply and battery management unit 4, and a data storage unit 5. The Bluetooth data transceiver unit 2, the key scanning unit 3, the power supply and battery management unit 4, and the data storage unit 5 are all connected to the keyboard control unit 1. The Bluetooth full-key conflict-free keyboard also 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 switching from the standard data packet mode to the non-standard data packet mode, or switching from the non-standard data packet mode to the standard data packet mode. Since the full-key conflict-free data packet is not a standard data packet mode, there is a compatibility problem. Therefore, we use the automatic switching of the two modes of 6-key conflict-free and full-key conflict-free. When the number of keys pressed is less than or equal to 6 keys, the 6-key conflict-free mode is used; when the number of keys pressed is greater than 6 keys, it automatically switches to the full-key conflict-free mode.

[0017] In this embodiment, the standard data packet mode corresponds to the 6-key non-conflict mode, and the non-standard data packet mode corresponds to the full-key non-conflict mode.

[0018] In this embodiment, in order to meet the current demand for using multiple devices at the same time, the Bluetooth full-key conflict-free keyboard also 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 at the same time, and quickly switch input between different devices through keys, meeting the needs of entertainment and office work at the same time.

[0019] The Bluetooth data transceiver unit 2 is a data transceiver unit based on Bluetooth 5.0 technology. Bluetooth uses Bluetooth 5.0 technology, which has a large amount of data sent and a fast speed.

[0020] The working method of the Bluetooth full-key conflict-free keyboard is as follows:

[0021] a. The key scanning unit 3 scans the keyboard. When the number of keys pressed is less than or equal to 6 keys, the keyboard data mode switching unit 6 is in the standard data packet mode, using the 6-key no-collision mode. The keyboard control unit 1 controls the Bluetooth data transceiver unit 2 to send a 6-key no-collision standard data packet, which can effectively improve the data transmission speed and accuracy;

[0022] b. The key scanning unit 3 scans the keyboard. When the number of keys pressed is greater than 6, the keyboard data mode switching unit 6 automatically switches from the standard data packet mode to the full-key conflict-free mode, and the keyboard control unit 1 controls the Bluetooth data transceiver unit 2 to send a full-key conflict-free standard data packet.

[0023] In this embodiment, the full-key non-collision standard data packet is a 14-byte data packet, each data bit represents a key, and 14 bytes can represent a total of 112 keys, that is, when all the keys on the keyboard are pressed at the same time, all the pressed keys can be sent out through one data packet, minimizing the amount of data sent. Figure 2 As shown, Figure 2 It is a full-key conflict-free data packet key mapping position table. The bit0 of the first byte of the data packet is position 1, bit7 is position 8, the bit0 of the second byte is position 9, and so on.

[0024] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
