Description

Technical Field

[0001] This invention relates to the field of communication technology, and also to a star flash signal transmission system and method. Background Technology

[0002] NearLink, a next-generation short-range wireless connectivity technology, integrates the advantages of Bluetooth and Wi-Fi, achieving breakthrough improvements in low latency, high reliability, precise synchronization, and high concurrency. It can be widely applied in smart cars, intelligent manufacturing, and smart homes. The communication distance between a NearLink G-node (Grant Node, management node) and a NearLink T-node (Terminal Node) is determined by parameters such as transmit power, receive sensitivity, antenna gain, and wireless signal attenuation. Wireless signal attenuation is determined by the actual installation and usage scenario; in some scenarios, such as at the corners of coal mine tunnels, attenuation is very significant. Existing technologies typically increase the transmit power of both the NearLink G-node and T-node, decrease the receive sensitivity, and increase the antenna gain to increase the communication distance between the G-node and T-node, or increase the number of G-nodes installed to ensure reliable data transmission from all T-nodes.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0019] An embodiment of the present invention provides a star flash signal transmission system, comprising: The first path is used to receive satellite flash band wireless signals in space, and to perform the first signal fine-tuning, signal merging, first filtering and signal amplification on the satellite flash band wireless signals to obtain the amplified signal and send it to the second path. The second channel is used to receive the amplified signal, and to perform a second filtering, signal splitting, and second signal fine-tuning on the amplified signal to obtain the split signal and transmit it.

[0020] The star-flash signal transmission system of this invention receives star-flash frequency band wireless signals in space through a first channel, and performs a first signal fine-tuning, signal merging, a first filtering, and signal amplification on the star-flash frequency band wireless signals to obtain an amplified signal, which is then sent to a second channel. The second channel receives the amplified signal, and performs a second filtering, signal splitting, and a second signal fine-tuning on the amplified signal to obtain a split signal, which is then transmitted. The system captures and optimizes the signal through the first channel, and then conditions the signal through the second channel before stable transmission. This eliminates the need to increase the number of star-flash management nodes or replace the star-flash equipment with one that has higher transmission power and higher antenna gain, which helps to save communication costs and increase transmission efficiency.

[0021] like Figure 1 As shown, in an optional embodiment of the present invention, the first path includes: First satellite flash band orthogonal antenna 11; A first amplifier 17 electrically connected to the first star flash band orthogonal antenna 11; The first star flash band orthogonal antenna 11 and the first amplifier 17 are sequentially electrically connected to the first phase adjuster 12, the first combiner 13, the first directional coupler 14, the first filter 15 and the first circulator 16; The first star-flash band orthogonal antenna 11 receives two star-flash band wireless signals in space.

[0022] Specifically, the first path receives and optimizes the satellite flash band wireless signal through the above structure to provide sufficient signal energy for subsequent transmission.

[0024] Specifically, the second channel conditions and stabilizes the received amplified signal for transmission, ensuring the stability, compliance, and efficiency of signal transmission.

[0025] like Figure 1 As shown, in an optional embodiment of the present invention, the second path further includes a second amplifier 27, which is electrically connected to the second circulator 26 and the first circulator 16.

[0026] Specifically, when the second path acts as the receiving end, the second star flash band orthogonal antenna 21 receives two star flash band wireless signals in space. The two star flash band wireless signals are sequentially fine-tuned by the second phase adjuster 22, combined by the second combiner 23, coupled by the second directional coupler 24, filtered by the second filter 25, isolated by the second circulator 26, and amplified by the second amplifier 27 to obtain an amplified signal, which is then sent to the first path.

[0027] The first circulator 16 in the first path receives the amplified signal. The amplified signal is then isolated by the first circulator 16, filtered by the first filter 15, coupled by the first directional coupler 14, split by the first combiner 13, and fine-tuned by the first phase adjuster 12 to obtain the split signal, which is then transmitted.

[0028] like Figure 1 As shown, in an optional embodiment of the present invention, the system further includes: Detector 31 is electrically connected to the first directional coupler 14 and the second directional coupler 24; An analog-to-digital converter 41 is electrically connected to the detector 31; The controller 51 is electrically connected to the analog-to-digital converter 41, the first phase adjuster 12, and the second phase adjuster 22; The first directional coupler 14 sends the coupled signal with a preset coupling ratio to the detector 31. The detector 31 converts the coupled signal into a DC signal and sends it to the analog-to-digital converter 41. The analog-to-digital converter 41 performs analog-to-digital conversion on the DC signal to obtain a digital signal and sends it to the controller 51. The controller 51 adjusts the phase of the first phase adjuster 12 according to the digital signal.

[0029] Specifically, the controller adjusts the phase through a phase adjuster while detecting the strength of the signal after filtering and amplification. Adjusting the phase to maximize the signal strength can improve signal transmission efficiency and system reliability.

[0030] In an optional embodiment of the present invention, the detector 31 is a true root mean square detector.

[0031] Specifically, the detector detects the received coupled signal, converts the radio frequency signal into a DC signal, and sends it to the analog-to-digital converter. Here, the detector is a true root-mean-square detector, which can accurately monitor the signal power status, ensure transmission stability, and optimize system performance.

[0032] like Figure 2As shown, in an optional embodiment of the present invention, the circuit of the first directional coupler 14 includes: The external reference signal terminal P1, amplifier A1, coupler U1, first capacitor C1, second capacitor C2, third capacitor C3, fourth capacitor C4, first inductor L1, first resistor R1, and second resistor R2 are connected. The external reference signal terminal P1 is connected to the input terminal of amplifier A1 through the third capacitor C3. The output terminals of amplifier A1 are all connected to one end of the first inductor L1 and one end of the fourth capacitor C4. The other end of the first inductor L1 is connected to one end of the first resistor R1. The other end of the first resistor R1 is connected to the grounded first capacitor C1 and the grounded second capacitor C2 and is connected to an external voltage. The other end of the fourth capacitor C4 is connected to the input terminal of coupler U1. The sixth pin 6 of coupler U1 is grounded through the second resistor R2.

[0033] Specifically, the circuit structure of the first directional coupler described above is only for illustrative purposes. In actual implementation, any type of directional coupler can be used, such as H3-MACPCT0030 or XINQY 2-8G, etc.

[0034] like Figure 3 As shown, in an optional embodiment of the present invention, the circuit of the detector 31 includes: The following components are connected to the network: a second inductor L2, a logarithmic detector A6, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, an eighth capacitor C8, and a ninth capacitor C9. One end of the second inductor L2 is connected to the coupling terminal of either the first directional coupler 14 or the second directional coupler 24. The other end of the second inductor L2 is connected to one end of the eighth capacitor C8. The other end of the eighth capacitor C8 is connected to one end of the fifth resistor R5 and the grounded fourth resistor R4. The other end of the fifth resistor R5 is connected to one end of the fifth capacitor C5 and the grounded ninth resistor R9. The other end of each resistor is connected to one end of the sixth resistor R6 and the second pin 2 of the logarithmic detector A6. The other end of the sixth resistor R6 is connected to the third pin 3 of the logarithmic detector A6 and the grounded ninth capacitor C9. The first pin 1 of the logarithmic detector A6 is connected to one end of the tenth resistor R10 and the grounded seventh capacitor C7. The other end of the tenth resistor R10 is connected to an external voltage. The fourth pin 4 of the logarithmic detector A6 is connected to one end of the resistor R18 and the grounded sixth capacitor C6.

[0035] Specifically, the circuit structure of the detector described above is only for illustrative purposes. In actual implementation, any type of detector can be used, such as SN5-SCG-900, etc.

[0036] In an optional embodiment of the present invention, both the first filter 15 and the second filter 25 are bandpass filters.

[0037] Specifically, bandpass filters have the advantages of purifying target signals, suppressing interference, and ensuring transmission quality. In this embodiment, using a bandpass filter as the first filter or the second filter can improve the overall performance of the system.

[0038] In an optional embodiment of the present invention, both the first combiner 13 and the second combiner 23 are 3dB bridge circuits.

[0039] Specifically, the 3dB bridge has both combining and splitting functions. It can act as a combiner to stably combine two signals of the same frequency into one, and it can also act as a second combiner 23 to split a single composite signal into the original I / Q quadrature signals, achieving efficient synthesis of signals of the same frequency and maintaining the consistency of signal phase / amplitude. At the same time, it has good port isolation and impedance matching characteristics. Using the 3dB bridge as the first combiner or the second combiner can improve the adaptability of the system and the signal transmission performance.

[0040] In an optional embodiment of the present invention, the first star flash frequency band orthogonal antenna 11 is aligned with the direction of the star flash management node antenna, and the second star flash frequency band orthogonal antenna 21 is aligned with the direction of the star flash terminal node antenna.

[0041] Specifically, the first and second satellite flash band orthogonal antennas serve two purposes: one acts as a receiver to receive satellite flash band wireless signals in space, and the other acts as a transmitter to transmit signals. Depending on the actual situation, the first satellite flash band orthogonal antenna can act as a receiver to receive signals from the satellite flash management node, and the second satellite flash band orthogonal antenna can act as a transmitter to transmit signals to the satellite flash terminal node; alternatively, the second satellite flash band orthogonal antenna can act as a receiver to receive signals from the satellite flash management node, and the first satellite flash band orthogonal antenna can act as a transmitter to transmit signals to the satellite flash terminal node; alternatively, the first satellite flash band orthogonal antenna can act as a receiver to receive signals from the satellite flash terminal node, and the second satellite flash band orthogonal antenna can act as a transmitter to transmit signals to the satellite flash management node; alternatively, the second satellite flash band orthogonal antenna can act as a receiver to receive signals from the satellite flash terminal node, and the first satellite flash band orthogonal antenna can act as a transmitter to transmit signals to the satellite flash management node.

[0042] A specific embodiment of the star flash signal transmission system of the present invention includes: like Figure 1As shown, the star flash signal transmission system of this embodiment of the invention does not require an integrated star flash module. It includes directional orthogonal antennas (first star flash band orthogonal antenna 11 and second star flash band orthogonal antenna 21), a phase adjuster, a combiner, a filter, an amplifier, a directional coupler, a detector, a circulator, an analog-to-digital converter, a controller, and a power supply circuit. Two directional orthogonal receiving antennas are aligned with the direction of the star flash T-node (terminal node). The received signal is filtered and amplified by the phase adjuster's input signal filtering and amplification circuit, and then transmitted through the other antenna. The controller adjusts the phase through the phase adjuster while simultaneously detecting the signal strength after filtering and amplification, adjusting the phase to maximize signal strength. The transmitting antenna must be aligned with the direction of the star flash G-node (management node). This solves the problem of insufficient transmission distance between the G-node and T-node. Figure 1 The two bidirectional arrows between the first satellite flash band orthogonal antenna 11 and the first phase adjuster 12, between the first phase adjuster 12 and the first combiner 13, between the second combiner 23 and the second phase adjuster 22, and between the second phase adjuster 22 and the second satellite flash band orthogonal antenna 21 represent one signal each. That is, there are two signal transmissions between the first satellite flash band orthogonal antenna 11 and the first phase adjuster 12, between the first phase adjuster 12 and the first combiner 13, between the second combiner 23 and the second phase adjuster 22, and between the second phase adjuster 22 and the second satellite flash band orthogonal antenna 21.

[0043] In specific implementation, the first satellite flash band orthogonal antenna 11 is aligned with the direction of the satellite flash G node antenna, and the second satellite flash band orthogonal antenna 21 is aligned with the direction of the T node antenna. The two antennas of the first satellite flash band orthogonal antenna 11 receive satellite flash band wireless signals in space. The satellite flash band wireless signals are transmitted to the first combiner 13 after passing through the first phase adjuster 12. The first combiner 13 combines the two signals into one and transmits it to the first directional coupler 14. The first directional coupler 14 transmits the signal to the first filter 15. The first filter 15 performs bandpass filtering on the signal and transmits it to the first circulator 16. The first circulator 16 transmits the signal to the first amplifier 17. The first amplifier 17 amplifies the signal and transmits it to the second circulator 26. The second circulator 26 transmits the signal to the second filter 25. The second filter 25 performs bandpass filtering on the signal and transmits it to the second circulator 26. Second directional coupler 24; Second directional coupler 24 couples out a very small portion of the signal (typically -30dB) to detector 31, and transmits the majority of the signal to second combiner 23; Second combiner 23 divides the signal into two orthogonal signals and transmits them to second phase adjuster 22; Second phase adjuster 22 transmits the two signals to second satellite stroboscopic band orthogonal antenna 21 respectively; Second satellite stroboscopic band orthogonal antenna 21 transmits the two signals; Detector 31 detects the signal coupled by second directional coupler 24, converts the radio frequency signal into a DC signal, and transmits it to analog-to-digital converter 41; Analog-to-digital converter 41 converts the received analog signal into a digital signal and transmits it to controller 51; Controller 51 detects the magnitude of the received digital signal and adjusts the phase of second phase adjuster 22 to maximize the received signal.

[0044] Similarly, the second stroboscopic band orthogonal antenna 21 also receives stroboscopic band radio signals in space, and amplifies and transmits the signals through the second phase adjuster 22, the second combiner 23, the second directional coupler 24, the second filter 25, the second circulator 26, the second amplifier 27, the second circulator 26, the first filter 15, the first directional coupler 14, the first combiner 13, the first phase adjuster 12, and the first stroboscopic band orthogonal antenna 11 in a similar manner. Similarly, the first directional coupler 14 couples out a very small portion of the signal (usually -30dB) to the detector 31. Similarly, the detector 31 detects the signal coupled by the first directional coupler 14, converts the radio frequency signal into a DC signal, and converts it into a digital signal through the analog-to-digital converter 41, which is then transmitted to the controller 51. The controller 51 detects the magnitude of the received digital signal and adjusts the phase of the second phase adjuster 22 to maximize the received signal.

[0045] Similarly, the first satellite flash band orthogonal antenna 11 can also be aligned with the T-node antenna direction, while the second satellite flash band orthogonal antenna 21 is aligned with the G-node antenna direction.

[0046] When the transmission distance between the StarSpark G node and T node is insufficient or the transmission effect is poor, the system of this invention can be used as an intermediary to increase the transmission distance or improve the transmission quality.

[0047] Compared with existing star-flash transmission technology, this invention does not require increasing the number of star-flash G nodes, nor does it require replacing the star-flash equipment with one that has higher transmission power and higher antenna gain. The system of this invention can be installed in a suitable location, which can greatly save system costs and increase transmission efficiency.

[0048] It should be noted that the first phase adjuster, first combiner, first directional coupler, first filter, first circulator, first amplifier, second phase adjuster, second combiner, second directional coupler, second filter, second circulator, second amplifier, detector, analog-to-digital converter, controller, etc. in the embodiments of the present invention can all use any model in the prior art, as long as the functions of each part can be realized. The circuit structure in the above embodiments is only for illustrative purposes.

[0049] like Figure 4 As shown, an embodiment of the present invention proposes a method for transmitting a star flash signal based on a star flash signal transmission system as described in any of the above embodiments, comprising the following steps: Step 401: The first channel receives the star flash band wireless signal in space, and performs the first signal fine-tuning, signal merging, first filtering and signal amplification on the star flash band wireless signal to obtain the amplified signal and send it to the second channel. Step 402: The second channel receives the amplified signal, performs a second filtering, signal splitting, and a second signal fine-tuning on the amplified signal to obtain the split signal, which is then transmitted.

[0050] like Figure 4 As shown, optionally, the method further includes: Step 403: The first directional coupler 14 in the first path sends the coupled signal with a preset coupling ratio to the detector 31; In step 404, the detector 31 converts the coupled signal into a DC signal and sends it to the analog-to-digital converter 41. Step 405: The analog-to-digital converter 41 performs analog-to-digital conversion on the DC signal to obtain a digital signal, which is then sent to the controller 51. Step 406: The controller 51 adjusts the phase of the first phase adjuster 12 in the first path according to the digital signal.

[0051] The star flash signal transmission method of this invention receives star flash frequency band wireless signals in space through a first channel, and performs a first signal fine-tuning, signal merging, a first filtering, and signal amplification on the star flash frequency band wireless signals to obtain an amplified signal, which is then sent to a second channel. The second channel receives the amplified signal, and performs a second filtering, signal splitting, and a second signal fine-tuning on the amplified signal to obtain a split signal, which is then transmitted. This method does not require increasing the number of star flash management nodes, nor does it require replacing the star flash equipment with one that has higher transmission power and higher antenna gain, which helps to save communication costs and increase transmission efficiency.

[0052] It should be noted that in the apparatus and method of the present invention, it is obvious that the components or steps can be decomposed and / or recombined.
