Description

Bluetooth communication system, Bluetooth communication device, Bluetooth communication chip, Bluetooth communication method and wireless signal transmission method

This case relates to Bluetooth communication technology, and in particular to a Bluetooth communication system, a Bluetooth communication device, a Bluetooth communication chip, a Bluetooth communication method, and a wireless signal transmission method.

With the development of technology, Bluetooth communication technology has gradually matured and stabilized, so that electronic products on the market currently use Bluetooth communication technology as one of their communication methods, such as Bluetooth headsets, wearable bracelets, wearable watches, car Android phones, smartphones, tablets, laptops and smart home appliances.

However, existing Bluetooth communication technology still has some problems to be solved. First, existing Bluetooth communication technology has a maximum communication distance limitation. Therefore, if the distance between two electronic devices exceeds the maximum communication distance supported by Bluetooth communication technology, at least one communication node (for example, at least one electronic device) needs to be set between the two electronic devices so that the two electronic devices can communicate.

In addition, existing electronic devices cannot establish multiple Bluetooth channels with multiple other electronic devices at the same time. Therefore, two electronic devices that are farther apart than the maximum communication distance of Bluetooth communication technology need to use one or more Bluetooth communication nodes between them as relay stations to establish a Bluetooth communication route. Since each relay's Bluetooth communication node can only establish one Bluetooth channel at the same time, when data is transmitted along this Bluetooth communication route, the relay's Bluetooth communication node must first establish a Bluetooth channel with the upstream node to receive data from the upstream node. After completing the data reception, the aforementioned relay Bluetooth communication node will interrupt the Bluetooth channel between it and the upstream node, and instead establish a Bluetooth channel with the downstream node, and transmit the received data to the downstream node. In other words, the data transmission rate of the Bluetooth communication line under this architecture will be greatly delayed, and this delay mainly comes from the fact that the relay Bluetooth communication node must repeatedly perform the "establishment-disconnection" process of the Bluetooth channel before the two electronic devices can communicate. Furthermore, since there is no other communication line between the two electronic devices, if any Bluetooth communication node in the Bluetooth communication line is damaged, the two electronic devices will not be able to communicate.

In view of this, the inventor proposes a Bluetooth communication system, a Bluetooth communication device, a Bluetooth communication chip, a Bluetooth communication method and a wireless signal transmission method. In some embodiments, the Bluetooth communication system includes a plurality of Bluetooth communication devices, and each Bluetooth communication device includes a Bluetooth communication chip and a processing chip.

Taking FIG. 1 and FIG. 9 as examples, in this embodiment, the Bluetooth communication chip 100 in each Bluetooth communication device 10A/10B/10C/10D/10E/10F/10G includes four Bluetooth communication modules 101A, 101B, 101C, and 101D. Therefore, each Bluetooth communication device 10A/10B/10C/10D/10E/10F/10G can simultaneously establish four Bluetooth channels CX with four Bluetooth communication devices 10 at most.

Please further refer to FIG. 10 , which is an operation flow chart of an embodiment of the Bluetooth communication system 1 in FIG. 9 . As shown in FIG. 10 , when the Bluetooth communication system 1 starts to operate, the Bluetooth communication system 1 first establishes a plurality of Bluetooth channels CX (step S13). Then, one of the plurality of Bluetooth communication devices 10 in the Bluetooth communication system 1 (hereinafter referred to as the Bluetooth communication device 10) receives a wireless signal SW from an electronic device through one of the plurality of Bluetooth channels CX, the antenna module 102 and the Bluetooth communication module 101 (step S14). Subsequently, the Bluetooth communication device 10 transmits the wireless signal SW from the Bluetooth communication module 101 to another Bluetooth communication module 101 (step S15). The Bluetooth communication module 101 and another Bluetooth communication module 101 are both installed in the Bluetooth communication device 10. Finally, the Bluetooth communication device 10 sends the wireless signal to another electronic device through another Bluetooth communication module 101, the antenna module 102 and another one of the plurality of Bluetooth channels CX (step S16). In some embodiments, the electronic device may be an electronic product with Bluetooth communication function, such as but not limited to a Bluetooth headset, a wearable bracelet, a wearable watch, an Android car, a smart phone, a tablet computer, a laptop computer and a smart home appliance. In other embodiments, the electronic device may be the Bluetooth communication device 10 of any of the aforementioned embodiments.

Taking FIG. 9 as an example, in this embodiment, the electronic devices in the aforementioned steps are all Bluetooth communication devices 10. Here, when the Bluetooth communication system 1 shown in FIG. 9 starts to operate, the Bluetooth communication system 1 establishes a plurality of Bluetooth channels C1 to C9 (corresponding to step S13). Assuming that there is a wireless signal SW in the Bluetooth communication system 1 to be transmitted from the Bluetooth communication device 10A to the Bluetooth communication device 10E, the Bluetooth communication system 1 can receive the wireless signal SW from the Bluetooth communication device 10A through the Bluetooth channel C1, the antenna module 102 in the Bluetooth communication device 10B, and one of the plurality of Bluetooth communication modules 101 (hereinafter, the Bluetooth communication module 101A is used as an example) (corresponding to step S14). Next, the Bluetooth communication device 10B of the Bluetooth communication system 1 transmits the wireless signal SW from the Bluetooth communication module 101A to another one of the plurality of Bluetooth communication modules 101 (hereinafter, the Bluetooth communication module 101B is used as an example) (corresponding to step S15). Subsequently, the Bluetooth communication device 10B of the Bluetooth communication system 1 sends the wireless signal SW to the Bluetooth communication device 10C through the Bluetooth communication module 101B, the antenna module 102 and the Bluetooth channel C3. Finally, the Bluetooth communication system 1 repeatedly executes steps S13 to S15 through the Bluetooth communication device 10C to transmit the wireless signal SW from the Bluetooth communication device 10C to the Bluetooth communication device 10E, thereby completing the transmission process of the wireless signal SW.

It should be noted that in some embodiments, the Bluetooth communication system 1 can also transmit the wireless signal SW through other Bluetooth channels CX and Bluetooth communication devices 10. In other words, the Bluetooth communication system 1 can select a route for transmitting the wireless signal SW according to different situations. For example, when the Bluetooth communication device 10C is damaged and cannot transmit the wireless signal SW, the Bluetooth communication system 1 can also transmit the wireless signal SW from the Bluetooth communication device 10A to the Bluetooth communication device 10E through the Bluetooth channels C2, C8, C9 and the Bluetooth communication devices 10F and 10G.

Please further refer to FIG. 11 , which is a module block diagram of another embodiment of the Bluetooth communication system 1. In some embodiments, the Bluetooth communication system 1 includes at least one electronic device 11, and the electronic device 11 can only establish one Bluetooth channel CX with one Bluetooth communication device 10 (hereinafter referred to as the first Bluetooth communication device 10) at a time. In other words, when the electronic device 11 wants to perform Bluetooth communication with another Bluetooth communication device 10 (hereinafter referred to as the second Bluetooth communication device 10), the electronic device 11 needs to first interrupt the Bluetooth channel CX between it and the first Bluetooth communication device 10, and then it can establish the Bluetooth channel CX between it and the second Bluetooth communication device 10.

As shown in FIG. 11 , in this embodiment, the Bluetooth communication system 1 includes two electronic devices 11A and 11B. Here, when the Bluetooth communication system 1 shown in FIG. 10 starts to operate, the Bluetooth communication system 1 establishes a plurality of Bluetooth channels C1 to C10 (corresponding to step S13). Assuming that there is a wireless signal SW in the Bluetooth communication system 1 to be transmitted from the electronic device 11A to the electronic device 11B, the Bluetooth communication system 1 can receive the wireless signal SW from the electronic device 11A through the Bluetooth channel C6, the antenna module 102 in the Bluetooth communication device 10C, and one of the plurality of Bluetooth communication modules 101 (hereinafter, the Bluetooth communication module 101B is used as an example) (corresponding to step S14). Next, the Bluetooth communication device 10C of the Bluetooth communication system 1 transmits the wireless signal SW from the Bluetooth communication module 101B to another one of the plurality of Bluetooth communication modules 101 (hereinafter, the Bluetooth communication module 101C is used as an example) (corresponding to step S15). Subsequently, the Bluetooth communication device 10C of the Bluetooth communication system 1 sends the wireless signal SW to the Bluetooth communication device 10D via the Bluetooth communication module 101C, the antenna module 102 and the Bluetooth channel C3. Finally, the Bluetooth communication system 1 repeatedly executes step S13 to step S15 through the Bluetooth communication devices 10D, 10E, and 10F to transmit the wireless signal SW from the Bluetooth communication device 10C to the Bluetooth communication devices 10D, 10E, 10F, and the electronic device 11B in sequence, thereby completing the transmission process of the wireless signal SW.

It should be noted that in some embodiments, the Bluetooth communication system 1 can also transmit the wireless signal SW from the electronic device 11 through other Bluetooth channels CX and the Bluetooth communication device 10. For example, when the Bluetooth communication device 10D is damaged and cannot transmit the wireless signal SW, the Bluetooth communication system 1 can also transmit the wireless signal SW from the electronic device 11A to the electronic device 11B through the Bluetooth channels C3, C4, C6, C8, C10 and the Bluetooth communication devices 10B, 10C, 10E, 10F.

In some embodiments, at least one of the plurality of Bluetooth communication devices 10 of the Bluetooth communication system 1 may first process the wireless signal SW through the processing chip 110, and then send the processed wireless signal SW to the subsequent device. Taking FIG. 9 as an example, when the Bluetooth communication device 10C receives the wireless signal SW, the processing chip 110 of the Bluetooth communication device 10C may first process the wireless signal SW (for example, but not limited to, adjusting at least one of the frequency, amplitude, phase, and pulse width of the wireless signal SW), and then send the wireless signal SW to the Bluetooth communication device 10E. Taking FIG. 11 as an example, when the Bluetooth communication device 10F receives the wireless signal SW, the processing chip 110 of the Bluetooth communication device 10F may first process the wireless signal SW and then send the wireless signal SW to the electronic device 11B.

In some embodiments, the antenna module 102 may be a hardware component having a wireless signal transmission function, such as but not limited to a monopole antenna, a dipole antenna, a loop antenna, a patch antenna, a planar inverted F antenna (PIFA), and a slot antenna.

In some embodiments, the amplifier module 103 may be a hardware component having a signal amplification function, such as but not limited to an amplifier, a bipolar junction transistor (BJT), and a metal oxide semi-conductor field effect transistor (MOSFET).

In some embodiments, the Bluetooth communication chip 100 has a printed circuit board (PCB), and the plurality of Bluetooth communication modules 101 and the antenna module 102 are individually packaged as a plurality of integrated circuits (ICs). Here, the plurality of Bluetooth communication modules 101, the antenna module 102, and the plurality of amplifier modules 103 can be soldered on the printed circuit board. Similarly, in some embodiments, the plurality of amplifier modules 103 shown in FIG. 3 can also be individually packaged as a plurality of integrated circuits and soldered on the printed circuit board.

In this way, the Bluetooth communication device including the Bluetooth communication chip can simultaneously establish multiple Bluetooth channels with multiple devices (including other Bluetooth communication devices and electronic devices), so that the Bluetooth communication system including the Bluetooth communication device has multiple transmission routes to choose from when transmitting wireless signals, thereby reducing the probability of signal transmission interruption caused by damage to an electronic device in the Bluetooth communication system. In addition, since each node in the Bluetooth communication system of this application establishes multiple Bluetooth channels in real time, there is no need to repeatedly execute the "establishment-disconnection" Bluetooth channel procedure when transmitting data in this Bluetooth communication system, thereby saving the time for re-establishing the Bluetooth channel, thereby improving the efficiency of the Bluetooth communication system during operation.
