[Previous technology] ~ It is known that traditional computers and peripheral devices must pass through an appropriate transmission interface and need to be connected to each other with a signal cable as a signal conversion action and data transmission; recently, USB has been further used A new generation of computer equipment with a communication interface can receive various wireless peripheral devices via a wireless signal transmitter and receiver, and transmit control signals through a USB signal transmitter, so that each USB peripheral device can be controlled wirelessly (WIRELESS). The purpose of operating a computer. In the application of USB wireless keyboards, because USB keyboards and PS2 keyboards have obvious differences in characteristics, the wireless transmission protocol needs to be designed for these characteristics to meet the requirements. In particular, in the repeated identification code during keyboard operation, when most keys are pressed sequentially, the USB keyboard transmits signals repeatedly with each key pressed, and the PS2 keyboard uses the last key. Repeat the transmission of the letter. In addition, regarding the remote remote wake-up function, on the USB keyboard, when the key interrupt code disappears, the identification code in the buffer (BUFFER) needs to be cleared, otherwise it will cause the key to be repeatedly pressed. Imaginarily, because the keyboard needs to be fixed for a certain period of time to repeatedly send out the identification code, it is easy to cause the transmitter module to repeat the action and cause waste of power. When the system enters the standby state, this phenomenon may even affect the normal operation of the remote wake-up function. [Summary of the Problem] This is a problem—the problem needs to be improved. The present invention provides a USB wireless key 5-disk ^ input protocol 'special wire for use in electric companies and USB wireless keyboard devices to effectively solve the aforementioned repeated identification, which may cause The error is that 'the main purpose of the present invention is to provide _ a kind of USB wireless Π USB wireless keyboard and computer host, fast and effective use == 疋 for signal operation and remote start button operation, shorten the receiver and The identification time of the transmitter for the identification code can save the crane consumers during USB standby. According to the present invention, the “USB wireless keyboard transmission protocol is closed when the keyboard is normally transmitted to identify the keyboard, and the plus-pure short handle (DUMmycod) is received by the RF module” is used to shorten the identification time to improve efficiency and Can save power consumption during USB standby. When the USB enters the standby state, the remote remote control operation must be started when the button is pressed. Read, change and wake up. In order to save the power to meet the standby power requirements of the standby state, the receiver needs to supply power to the RF within a period of time. Module to receive the identification code transmitted by the keyboard; using the transmission protocol of the present invention, the keyboard adds some additional and shorter special codes at the interval between the normal transmission of the identification code, and _short identification time 'receiving II does not need to be Stopping the power supply can save power consumption, ensure system stability, and achieve the intended purpose.

[Embodiment] The USB wireless keyboard transmission protocol of the present invention is applied to a computer system using a wireless peripheral device, particularly a USB wireless keyboard. The above-mentioned invention uses the signal transmitting module on the keyboard. When the keyboard is in the interval of transmitting the identification code normally, please refer to the first picture, the second picture and the third picture. The transmitting and receiving principle of the module and the receiving module. When the transmitting module is in normal use, when the user presses the keyboard, the transmitted packet is the data packet D shown in the first figure, and the format of the data packet D is栝 In the beginning, D and some information £) 2 and a check summary (DCK3), it is expected that one :: =: 2 The packet period is T1 ', and the interval between the transmission period T1 when the key is pressed is shown in ^ The packet perimeter of each packet D is generally entered to pull her call. To achieve the goal of saving power at the receiving end, the receiving receiver needs to periodically check whether the disk end is already in use, ί the receiving period T3 and standby duty T4, the secret collection period ί, 2 the same county V tT1 the same length, and standby The period T4 is kept open with the interval _1 and vice versa =: =, the receiver's module module source is cut off _. In the standby period T4, the receiver's RF module power transmission times M, p ° te not shown in the fourth picture. In order to correctly determine whether the keyboard transmitting end is within the W receiving period T3> (greater than) the packet period T1, standby Period T4 < (the invention of the present invention is exactly the same as when the keyboard is in the transmitting mode == the second phase T2, adding some additional and shorter special codes, and transmitting the reverse data +4 J ^ 〇DE) as the identification signal, that is, when the keyboard The data is transmitted when the key is pressed. == 捭: Multi-transmit some data packets. The special spoon L makes the reducer end repeatedly repeat the _receive_ acknowledge signal to inform the user that the data buffer (DATABUFFER) does not need to be cleared. Will not cause errors. When the receiver normally receives the packet D, the special code Dc can be removed. When the special code 1 ^ is continuously received, it means that the keyboard is deleted and the receiving group (0Γ LR.LED) is in a normal working state. It is necessary to supply power to the RF module, and it can reduce the time required for identification and greatly improve efficiency. When the device enters the standby state and judges whether the keyboard is transmitting data, the special code DC is used as the judgment standard. @This we can reduce the receiving cycle T3 on the receiver side a lot, standby_T4 is lengthened. The shorter the connection T3 at the receiving end, the longer the standby period T4 and the more power saving. 'The following example illustrates that the content of the special code DC and the data packet D can be guaranteed to differ. Among them, when the data packet D is in the packet period T1 1: coding-> 0,1 〇: coding-> 1,0 special code DC -> 00111100 is free from interference, and can save the device with a good transmission product. This method can provide USB fast identification signal, power consumption during USB standby, make the receiver and transmitter quality. Therefore, it can be known that the above-mentioned USB wireless disk of the present invention ~ uses a keyboard signal transmitter to hold / agree between the normal identification codes, which is a profit code to inform the signal receiver to ensure that the USB sends a short special identification in normal operation. Time, and can improve the stability of USB signal transmission, not only reduce the signal, the above-mentioned present invention has been described in detail, so that those who are familiar with the present disclosure purpose. The above-mentioned embodiments are only used for illustration, for example, wherever the implementation of the 'but the limbs of the spirit of the present invention, belong to the structural changes of the invention and do not file a patent application for this' The patent in this case is to check for ^ f and pray for early [Simplified Illustration] Figure-Figure ^ The conventional packet data format of the USB wireless keyboard transmitter end indicates the second packet packet cycle and interval of the wireless keyboard transmitter The waveform diagram of the cycle; The third diagram is the receiving cycle and standby cycle of the receiving end of the conventional USB wireless keyboard. The fourth diagram is the waveform diagram of the special code of the packet cycle and the interval meaning of the present invention.
