One of the data transmission ends is The received data is directly sent to a data receiving end, and there are actually many problems in this wiring transmission architecture. However, such a non-first, transmitting end is in the previous receiving state when sending data, so usually it is necessary to delay the transmission time of 2 packets that cannot be received by the receiving end. In contrast, the preamble receives the transmitting end. The data sent is also in order to receive the material in real time. Therefore, the 'wireless transmission wheel' maintains the receiving data efficiency and wastes a lot of power.

V. Description of the Invention (7) FIG. 2 shows a schematic diagram of a packet transmission protocol between the interface module 20 and the opposite remote module 30 in this embodiment. When the interface module 20 is connected to the host 10 and the installation and configuration process is completed, the USB device will enter a configured state. At this time, the processor 24 of the interface module 20 drives the wireless transmission circuit 24 and periodically sends an inquiry packet 100 to the opposite remote module 30. On the other hand, when there is data in the relatively remote module μ that needs to be transmitted, the processor 32 will temporarily store the data to be transmitted in the temporary register 'waiting for the inquiry packet 1 from the interface module 2 〇 〇. After the relative remote module 30 has correctly received the inquiry packet 100 from the interface terminal module 20, it can encapsulate the data in the register within a predetermined time and generate a data packet of 20, And sent to the interface module 20. When the interface module 丨 module 20 correctly receives the data packet 2000, it will also return a confirmation packet 300 within a predetermined period of time. As long as the relative remote module 30 receives the ^ confirmation packet 300, it means that this data has been correctly transmitted from the relatively remote module 30 to the interface terminal module 20. It must be noted that the above-mentioned inquiry packet 100, data packet 2000, and confirmation packet 300 are all transmitted by wireless transmission. FIG. 3A shows a schematic diagram of the packet structure in this embodiment, which is a common packet of the above-mentioned inquiry packet 100, data packet 200, and confirmation packet 300. As shown in FIG. 3A, the packet in this embodiment includes the following parts: (preamble packet 60, start bit 62, identification code 64, packet type (packet type) 66 and stop bit 68, in which the type 66 part of the packet will vary with different packets. No matter what kind of packet, the packet is prepared 6 ^

V. Description of Invention (8) The beginning 'is for receiving data, not noise. It is enough to recognize this as the correct packet start bit 62 and end bit 6: 3. Other data 'will be encapsulated at the end to correctly identify this packet as: Library: = Lets the receiver distinguish between different USB devices. The n1w's transmission knows the type of this packet. In the source. The packet type 66 is used to indicate the inquiry packet_, the data packet = 2, and the 3D image represents the above packet structure = 1 packet to ^ ^ L〇〇H〇 ^ 1 〇 ^ ^ ^ ^ , The inquiry packet j 0 〇 county group 20 is transmitted to the relative remote module 3G = interface end, No. On the other hand, the inquiry packet 10 was received relatively at = J. ， Lai Er is in normal working condition, and then as a correct response 2 ° 疋 In Figure 3C, the data packet stop 2 丨 is used to indicate ~ followed by the data that needs to be transmitted 'content 2: Department, = 7 2 remote module 3. Received the inquiry packet _; This month b was transmitted to the interface module 20 months. For sure = 3 packets. Figure: As an example to indicate the packet system, give the phase can: greatly improve the data transmission Correctness. But when 5 is correct, the situation line is 515177 V. Invention description (9) Transmission efficiency is saved. Explaining the wireless transmission protocol and in this embodiment, the following describes the interface in the USB device ^ the actual operation method of the module 30 after the packet should be communicated. … 〇u and the processing flow of the relatively remote interface end module (20). FIG. 4 shows the operation flowchart of the interface end module 20 in the present embodiment when performing the orientation recording. When the interface module 20 is connected to the host, the USB controller on the host terminal 10 will be in accordance with the USB specification device (step S20). At this time, the interface terminal module = the interface circuit 22 obtains the host terminal i. The sent signal is transmitted through the heart 2 through the interface circuit 22 to respond to the correct data to the host terminal om to the entire installation and configuration process. And 6 ·! Nn After the installation and configuration are completed, the interface module 20 will start to send an inquiry cover: 〇 (: 观 1). At this time, the processor 24 will immediately enable the wireless transmission circuit 6, and the wireless transmission circuit 26 can periodically send an inquiry packet to the relative remote module 30, and waits for the reception from the relative remote module 30. 30 data packet 200 (step S22). The interface module 20 checks whether it has received a data packet 20 0 from the relatively remote module 30 within a predetermined time after each sending of the inquiry packet 100 (step S23). Among them, it is assumed that the transmission time of the inquiry packet 100 is represented by τι, and the above-mentioned waiting time for receiving the data packet 200 (the predetermined time is represented by T2. The predetermined time T2 is the time when the interface module 20 receives the data packet 2 0 The effective time is the minimum time when the interface module 2 〇 allows the remote module 30 to respond to the data packet 200 after sending the inquiry packet 100. The length of the time T 2 can be used by Decides when time τ 2

0715-6477TW; yen.ptd) 15177 V. Description of the invention (10) The longer it is, the larger the relative power consumption is, and the time τ 2 is too short, it may cause the relative terminal module 3 to have no time to return the data packet 2 q 〇. For example, if the interface module 20 receives a data packet 200 within the time T2, the processor 24 will send a corresponding confirmation packet 30 {) to the corresponding remote module. To inform that the data packet 2000 has been received correctly (step S24). Then 3: 2 5 Τ21 sends the next inquiry packet 100 to allow the remote module d 0 to transmit data. On the other hand, if the interface module 20 does not have a cloud ID within the above valid time, and the packet is 2000, it means that the remote module 3 does not need the USB to dream department # data. Next, it is first checked whether the host terminal 10 requires this electric mode (step S25). If there is no such request, the terminal = step S21 'continue to send the next inquiry packet 100; if the host enters the power saving mode 3 ί ί enters the power saving mode, the processor 24 will enter the Q f mode (Ϊ Step 26). * However, in the power-saving mode, the processor 24 still returns to step S21 and sends an inquiry packet 100. Here, s is longer than the normal mode. _ ^

Regarding the province's lightning protection nr k A, the length between the magic leaves depends on the USB. This part will be described in detail later. The smaller the power consumption of Μ4, the processing flow of execution = interface end mode can be divided into several different reads (al). When the interface end module 20 is in normal mode 30 and there is data to be transmitted, it will follow (step s2i) _> U remote module> (step S23)-> (step S24) one> (steps such as) sequence (execute; S22) Page 14 0715-6477TWF; yen.ptd J〇177 V. Description of the invention (11) (bl) When the interface module 20 has no data transmission in the normal module 30, it will follow the steps: to the terminal module ~ boat step sr only, 7 township ^ 1)-> ( Step S22) (/ Step 3): > (Step S25) _> (Steps such as) sequence (cl) * ^ face-end module 20 in the power-saving mold soil 3 0 泫 泫 杳 祖 自… # , 'Down and relative back-end die% ~ 4s23 ^ execute step S23)-> (step S25)-> (step S26) _> (step s2i) sequence (dl) when the interface end module 2〇 在In power-saving mode and oblique reading. # When there is data transmission, # execution sequence is the same as the case (al). Wu, and 1 According to the above, when there is continuous data transmission to the remote module 30, the interface module 20 can continuously receive the data packet 200 regardless of whether the interface module 20 is in the normal mode or the power saving mode. The difference between the interface module 20 in the normal y mode and the power saving mode is mainly due to the fact that the data packet 200 is not received. In the normal mode, the transmission period of the inquiry packet 丨 〇〇 is τ 丨(Transmission time) + T2 (data packet waiting time), and $ 100 in power saving mode is sent every time Tl + T2 + T3 (power saving mode interval time), where T3 is much larger than τΐ, Τ2, In this way, the current requirement η in the power saving mode is met. The processing flow of the remote module (30) is shown in FIG. 5. FIG. 5 shows an operation flowchart when the remote module 30 performs bidirectional wireless transmission in this embodiment. The opposite remote module 30 must obtain power supply (step S30) to start operation. The action relative to the remote module 30 is basically performed in cooperation with the interface module 20. First, the processor 32 will first confirm whether any data needs to be transmitted to the interface module 20 (step S31). If not

At this time, the processor core first sends to the wireless transmission circuit 34 and starts waiting for the receiving interface module 20 = packet 1G0.

Therefore, when the above = = t, so after dividing the data in the register (step S36), the switch mode (step S37) is the same. Ground, the processor 32 will determine the long button of the above-mentioned T4 on the next day by the user,

The description of the invention (13) is sent out (step S34). As mentioned above, the remote module must be loyal within the time T2 (data packet waiting time) specified by the interface module 20, and the packet must be 200. Then, the relative remote module 30 will wait to receive the confirmation packet 300 from the second-side module 20, and its waiting time is represented by T5. The confirmation packet 300 is not received within the second time T5 (step S35). The lean material packet 200 of 200 has not been correctly received by the interface module 20 for a long time. On the other hand, if the packet is 弋 °, it means that the data packet 200 is received normally, that is, it is confirmed that the packet is 300 μm (π + 4 to be seized). The short time for packet 300 is similarly determined by the user. If 砗 ητς, M, and / 15 are long, if the time T5i54r 0 is too long, time T5 will increase the energy loss.

Another important feature of the embodiment is that it can reliably achieve the power saving mode required by the USB specification, and this part is the second part of the conventional technology. The following describes the conventional technology and the operation mode of the embodiment in the power saving mode in detail with reference to the drawings. The diagram in the figure shows the operation timing diagram of the interface module in the conventional technology one-way wireless transmission, and the switch mode, and the figure 6β shows that in this implementation of the two-way wireless transmission, the interface module is in the province When operating in electrical mode ^ In the conventional technology shown in FIG. 6A, the wireless fork set of the interface module only has the function of receiving signals. Among them, the time of waiting for the receiving state in the power saving mode is represented by T6, that is, the interface module waits for the relatively remote mode.

V. Description of the invention (15) Time for transmitting data. In addition, the power saving status indicates that the processor will be turned off during this time; the power will be received by the T7 meter. Open the female knife, so it can not be connected in this embodiment shown in Figure 6B, = packet, and then wait for the relatively remote mode; wait: = = _ just _ send =. :: The use of ^ in the USB specification is represented by T3. The average power of the device is two. The power source device ’is in the power saving mode. At 实 1, the current is much smaller than that during normal operation. Therefore, in the case of two-mode two-mode USB transmission, the interface module saves power. ΓΓ The average current is very small. In order to achieve the average current, it can be regulated to enter the power-saving mode. In the mode, the power saving state is equal to n, (in this embodiment, T3; f knowing technology is 77), it must be much longer than the maintenance time of the working state (in this embodiment, Tl + T2; the conventional technology is τ6). # & However, ‘this kind of situation has problems in the conventional technology. In the case of one-way Lu Yu, since the remote module cannot grasp the interface terminal module is: in the receiving state (time T6) or power saving state (time T7), in order to ensure that the data can be captured The interface module received it correctly, so the sending time of each lean packet preparation packet must be longer than the power saving state dimension.

V. Description of the Invention (16) Hold time T7, the only function to wake up to the remote end. The value H does = the shell material can be received, and the length of the preliminary packet is very long; the distance = f will cause f in front of each piece of data, and the power consumption will increase several kilograms. The content of the data to be transmitted itself f: It's data 'This will also be equal to two in the preparation of the packet part, but in this embodiment, eight to a to its transmission efficiency. Actively send out inquiry packets. The face-end module can still wait to receive inquiry packets in the power saving mode. 〇 〇 jin is only required to wait for the remote module, and the remote module does not need to respond to the poor information. Packets of 200 are sufficient. In other words, in the power-saving mode, ^ = the length of the pre-packet portion is returned, and the transmission efficiency is obviously better than the conventional technique, whether it is power consumption or the second embodiment. The purpose of 雔 & in the present invention can be further: to enter into f: to use the group interface end device to achieve the phase z or more of the two groups shown in the first embodiment or the seventh embodiment. The second is the wireless transmission of data to the second core group. In the example of the opposite far-end module, a block diagram of the transmission structure using a single set of interface-end modules to two surface-end modules is shown. As shown in the figure, the wireless transmission wheel 7 is connected to the host via a wireless transmission path 7 and the wireless transmission wheel is expected. ^ Two-groups are connected to the remote modules 50a, 50b for resource 42, processor 4. As shown in the figure, the interface module 40 includes a USB interface, 50b, and wireless transmission circuit 46 respectively. Opposite remote module 50a 5 2b. As for j: = & wireless wheel circuits 54a, 54b and processor 52a, the details will be described again. That is, the transmission protocol is the same as that of the first embodiment. Here, the “side-end module 40” only needs to use a single wireless transmission power.

V. Description of the invention (17) Road 46, can be transmitted separately on the benefit line, with the savings of: = circuits 54a, 54b for data without this architecture.
