Description

Technical Field

[0001] The present invention relates to the technical field of relay systems, and in particular to an intelligent selective wireless data transmission relay system and a relay method. Background Art

[0002] In remote control, remote sensing, telemetry systems, and wireless data acquisition and control systems, star or tree topology structures are often used for data exchange between the master station and the slave station. In the ultra-short wave frequency band, line-of-sight transmission is the main method. When the master station and the slave station are far apart or there are obstacles in the middle, the master station and the corresponding slave station will not be able to exchange data or the interaction will be unstable. Adding repeaters at appropriate locations can effectively solve the distance extension problem.

[0003] The existing relay systems on the market perform transparent transmission and do not identify the target slave station. For example, if data needs to be forwarded to the target slave station No. 15, and the station No. 15 is far away from the master station, the relay system will forward all the slave stations No. 1 to 40 connected to the master station, without identifying the target slave station, so all are forwarded. The power consumption in the transmitting state is large. The greater the transmission power, the greater the power consumption. However, the power consumption is small when receiving data. In this case, the more times the repeater transmits, the heavier the burden on the relay system. In a system powered by solar energy, wind energy or batteries, traditional repeaters relay all data sent by the master station. The power supply system is difficult to support such a high frequency of transmission, and may even charge during the day and run out of battery energy at night. It is even more difficult to maintain in a rainy climate. Therefore, it is required that the existing repeaters cannot forward all data, and they need to selectively relay and forward data, forwarding those that need to be forwarded and not forwarding those that do not need to be forwarded.

[0004] The existing technology has defects and needs to be improved. Summary of the invention

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Embodiment 1

[0030] See also Figure 1 The present invention provides an intelligent selective wireless data transmission relay system, in which a master station wirelessly communicates with at least one slave station through a relay system, the relay system is provided with at least one repeater, the repeater participates in wireless networking, at least one address segment is provided in the repeater, and each address segment stores the address of at least one target slave station; the master station communicates with the corresponding target slave station in the address segment through the relay system.

[0031] In a preferred embodiment, the repeater is provided with two transceivers and an isolator, the two transceivers are isolated from each other by the isolator, the two transceivers are connected by a data line, the relay system is provided with a repeater, the transceiver of the master station is connected to one of the transceivers of the repeater via a wireless network, and the other transceiver of the repeater communicates with the transceiver of the slave station via a wireless network.

[0032] When only one repeater is needed in the communication link, the repeater is set between the master station and the target slave station, and the repeater is bound to the corresponding target slave station. The transceiver of the master station transmits data, and the data is received by one of the transceivers of the repeater, and the isolation is increased by the isolator. The other transceiver of the repeater performs selective forwarding to the target slave station bound to it, avoiding unnecessary forwarding. The transceiver of the target slave station receives and processes the data. When the data is returned, the transceiver of the target slave station transmits the return data, which is forwarded to the master station through the repeater, thereby realizing selective communication between the master station and the target slave station.

[0033] For example, Figure 1In the example, the master station binds slave #1 to slave #5 and slave #10, and the master station communicates with repeater A. Repeater A binds slave #6 to slave #9. The master station communicates with slave #1 to slave #5 and slave #10, and communicates with slave #6 to slave #9 through repeater A. During this process, repeater A selectively communicates only with slave #6 to slave #9, and repeater A no longer communicates with slave #1 to slave #5 and slave #10 outside its range, which greatly reduces the power consumption of repeater A.

[0034] Embodiment 2

[0035] See also Figure 2 The repeater includes two transceivers and an isolator. The two transceivers are isolated by the isolator. The two transceivers are connected by a data line. The relay system is equipped with multiple repeaters to realize multi-level relay. Multiple repeaters forward signals step by step through their transceivers. The transceiver of the master station is connected to the transceiver at the head end of the first repeater through a wireless network. The target slave stations are all connected to the transceiver at the end of the last-level repeater through a wireless network.

[0036] When at least two repeaters are required in a communication link, multiple repeaters are sequentially arranged between the master station and the target slave station, and the repeaters are sequentially bound to each other. The transceiver at the first stage of the first repeater is connected to the transceiver of the master station, and the transceiver at the end of the final repeater is bound to the corresponding target slave station. The transceiver of the master station transmits data, and the data is received by the sequentially connected repeaters. The transceiver at the end of the final repeater selectively forwards the data to the target slave station bound to it, thereby avoiding unnecessary forwarding. The transceiver of the target slave station receives and processes the data. When the data is returned, the transceiver of the target slave station transmits the return data, which is forwarded to the master station through the sequentially connected repeaters, thereby realizing selective communication between the master station and the target slave station.

[0037] For example, Figure 2 In the example, the master station binds slave #1 to slave #5 and slave #10, and communicates with repeater A. Repeater A binds slave #6 to slave #9 and communicates with repeater B. Repeater B binds slave #7 to slave #9. The master station realizes direct communication with slave #1 to slave #5 and slave #10, and realizes communication with slave #6 through repeater A. The master station realizes communication with slave #7 to slave #9 through the link of repeater A and repeater B. In this process, #relay A selectively communicates directly only with slave #6 and repeater B. Repeater A no longer communicates directly with slave #1 to slave #5 and slave #7 to slave #10 outside its range, and repeater B no longer communicates with slave #1 to slave #6 and slave #10 outside its range, which greatly reduces the power consumption of the repeater.

[0038] Embodiment 1 and Embodiment 2 only take 10 slave stations as examples for illustrating the problem. However, in general remote control, remote sensing, telemetry systems and wireless data acquisition and control systems, the data of slave stations are far more than 10. It is conceivable that when the number of slave stations is dozens or hundreds, the power saving will be huge.

[0039] Embodiment 3

[0040] When at least two repeaters are required in a communication link, multiple repeaters are arranged in a tree-like manner between the master station and the target slave station, and the repeaters are bound in a tree-like relationship. The transceiver of the first section of the first repeater is connected to the transceiver of the master station, and the transceiver at the end of the last-stage repeater is bound to the corresponding target slave station, and the repeaters in the communication link are all bound to the target slave station. The transceiver of the master station transmits data, and the data is received by the repeaters connected in sequence. After each repeater receives the data, it forwards the data to the target slave station bound to it and the next repeater. The transceiver at the end of the last-stage repeater selectively forwards the target slave station bound to it, avoiding unnecessary forwarding. The transceiver of the target slave station receives and processes the data. When the data is returned, the transceiver of the target slave station transmits the return data, which is forwarded to the master station through the repeaters connected in sequence, thereby realizing selective communication between the master station and the target slave station.

[0041] According to a preferred solution, the transceiver is further provided with an interface circuit and a microprocessor, wherein the interface circuit is connected to the microprocessor, and the interface circuit is used to connect to a PC to modify the address segment parameters stored in the microprocessor to modify the binding relationship between the repeater and the target slave station.

[0042] In a preferred solution, the transceiver is further provided with a debugging device, and the debugging device is used to debug the connection between repeaters, between a repeater and a master station, and between a repeater and a slave station.

[0043] In a preferred embodiment, the debugging device includes a voice input unit and a voice output unit, wherein the voice input unit is connected to the transmitter of the transceiver, and the voice output unit is connected to the receiver of the transceiver. The voice signal collected by the voice input unit is sent through the transmitter, and the receiver of the transceiver outputs an audio signal through the voice output unit for debugging and maintenance.

[0044] In a preferred embodiment, the transceiver also includes a phase-locked loop frequency synthesizer, which is connected to the microprocessor to generate a required operating frequency. The phase-locked loop frequency synthesizer includes a transmitting phase-locked loop frequency synthesizer and a receiving phase-locked loop frequency synthesizer. The transmitting phase-locked loop frequency synthesizer is connected to an antenna via a voltage-controlled oscillator and an exciter, and the receiving phase-locked loop frequency synthesizer is connected to the first mixer of a receiving channel to achieve reception of a specified frequency signal.

[0045] In a preferred embodiment, a power amplifier and at least one filter are arranged between the exciter and the antenna, the exciter is connected to the input side of the power amplifier, the input side of the filter is connected to the output side of the power amplifier, and the output side of the filter is connected to the antenna.

[0046] In a preferred solution, the filter is arranged in multiple stages, the multiple stages of filters are connected in sequence, the output side of the power amplifier is connected to the input side of the first stage filter, and the output side of the final stage filter is connected to the antenna.
