[0055] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0056] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a twisted pair extender capable of multi-channel bidirectional mutual transmission, comprising: a first transceiver, a twisted pair, and a second transceiver, the first transceiver and the second transceiver are connected via a twisted pair, the first transceiver acquires a digital signal, and uses multiple nodes to perform a first signal processing on the digital signal to obtain a target transmission signal, and then transmits the target transmission signal to the second transceiver via the twisted pair using a multi-channel bidirectional mutual transmission method, the second transceiver uses multiple nodes to perform a second signal processing on the received signal to obtain a target received signal, and forwards the target received signal to a target device.

[0057] In the above technical solution, the first transceiver is connected to a main control device or a collection device, such as a computer host, a surveillance camera, a computer, a video recorder, etc., and the second transceiver is connected to a playback device, such as a speaker, a display, a monitoring center, etc.

[0058] In the above technical solution, the digital signal is a signal related to audio and video.

[0059] In the above technical solution, the target transmission signal refers to a signal that complies with twisted pair transmission.

[0060] In the above technical solution, the target received signal refers to a playback signal adapted to the target device.

[0061] The above technical solution can not only eliminate the limitation of transmission distance through the twisted pair extender, realize multi-channel two-way mutual transmission and high-quality transmission of long-distance signals, reduce the loss of signals during transmission, ensure the quality of received signals, improve transmission performance, but also reduce time consumption, so that digital signals can be played in the target device in time, and realize real-time playback of video or audio signals. Two-way mutual transmission is realized through twisted pair, while reducing the interference of signal transmission, reducing the loss of signals during transmission, ensuring the quality of received signals, so that the target device can play high-quality video or audio signals; the first transceiver and the second transceiver use multiple nodes for signal processing, effectively improving the efficiency of signal processing, reducing the time efficiency, so that the digital signal can reach the target device in a shorter time, and then realize the real-time playback of video or audio signals.

[0062] like Figure 3 As shown, in one embodiment provided by the present invention, the first transceiver uses multiple nodes to perform first signal processing on the digital signal, including:

[0063] A1. Acquire digital signals and determine target digital signals;

[0064] A2. Perform a preliminary analysis on the target digital signal to determine whether the target digital signal needs to be processed in segments, and obtain a preliminary analysis result;

[0065] A3. Determine the signal processing scheme based on the preliminary analysis results, configure the nodes according to the signal processing scheme, and determine the target node;

[0066] A4. Extract the signal to be processed from the target digital signal through the target node in combination with the signal processing solution, and perform format standardization on the signal to be processed in combination with the target signal format to obtain the target transmission signal.

[0067] In the above technical scheme, when determining the target digital signal, a type analysis is performed on the digital signal to determine the type of the digital signal, and the signal is determined according to the type of the digital signal. When the type of the digital signal is an audio signal, the target digital signal is determined according to the first acquisition and determination scheme, and the digital signal is initially determined in combination with the first preset time, and the terminal signal characteristics are analyzed. Then, it is determined whether adjustment is required based on the terminal signal characteristics to obtain a first analysis result, and the initially determined digital signal is adjusted according to the first analysis result to obtain the target digital signal; when the type of the digital signal is a video signal, the target digital signal is determined according to the second acquisition and determination scheme, and the digital signal is determined in combination with the second preset time to obtain the target digital signal; when the type of the digital signal is a mixed signal, the target digital signal is determined according to the third acquisition and determination scheme, and the first signal determination is performed on the digital signal in combination with the third preset time, and the terminal signal separation and feature analysis are performed on the first signal to obtain the terminal audio characteristics. It is determined whether signal adjustment is required based on the terminal audio feature analysis to obtain a second analysis result, and the first signal is adjusted according to the second analysis result to obtain the target digital signal.

[0068] In the above technical solution, when performing preliminary analysis on the target digital signal, the signal parameters of the target digital signal are obtained, and whether the target digital signal needs segmented processing is determined based on the signal parameters and the segmented processing standard to obtain a preliminary analysis result, wherein the segmented processing standard is a segmentation rule determined in advance in combination with the node performance limit.

[0069] In the above technical solution, the target signal format is a signal format that complies with twisted pair transmission.

[0070] The above technical solution realizes efficient processing of digital signals by using multiple nodes to process the first signal of digital signals at the first transceiver end, so that the twisted pair extender can better transmit signals when processing digital signals, avoiding the incompatibility of digital signals and causing inability to transmit or invalid transmission. By making a preliminary analysis of the target digital signal to clarify whether the target digital signal needs to be processed in segments, it is avoided that the target digital signal exceeds the performance limit of the target node, causing errors in the first signal processing or affecting the effect of the first signal processing, and providing a guarantee for the determination of the target transmission signal; and by configuring the nodes according to the signal processing scheme, multi-node processing is performed according to the needs of the digital signal, reducing resource waste, and at the same time, it can also ensure efficient signal processing and reduce time waste. And by combining the target signal format with the format specification of the signal to be processed, the format of the target transmission signal is unified, so that the target transmission signal is adapted to the twisted pair, so that the twisted pair can better transmit the target transmission signal, improve the effectiveness of the twisted pair signal transmission, and then provide a guarantee for the long-distance transmission of the target transmission signal.

[0071] In one embodiment provided by the present invention, when format specification is performed on the signal to be processed in combination with the target signal format, format specification is performed on the signal to be processed in the target node, including:

[0072] Acquire the current format of the signal to be processed to obtain the current format information of the signal to be processed;

[0073] Analyze whether the current format information of the signal to be processed is the same as the target signal format, and obtain the format analysis result;

[0074] Different methods are used to determine the target transmission signal according to the format analysis results; when the format analysis result is that the current format information of the signal to be processed is the same as the target signal format, an identification signal is obtained for the target node based on the signal processing scheme to obtain the target node identification information, and the signal to be processed is marked in combination with the target node identification information to obtain the target transmission signal; when the format analysis result is that the current format information of the signal to be processed is different from the target signal format, an identification signal is obtained for the target node based on the signal processing scheme to obtain the target node identification information, a format conversion model is called according to the current format information, and a signal format conversion is performed through the format conversion model according to the signal to be processed and the target node identification information to obtain the target transmission signal.

[0075] In the above technical solution, the target transmission signal includes both the signal to be processed and the target node identification information.

[0076] In the above technical solution, the format conversion model is a format conversion framework pre-constructed for the signal to be processed and the target node identification information. It can directly realize the conversion of the target format according to the signal to be processed and the target node identification information, convert the signal to be processed into a signal in the target format, and also integrate the target node identification information into the signal in the target format to obtain the target transmission signal.

[0077] The above-mentioned technical solution can clarify whether the current format information is the same as the target signal format by obtaining the current format of the signal to be processed, and then can perform different processing according to the actual situation of the signal to be processed to determine the target transmission signal, avoiding time waste caused by invalid steps, and by combining the target node identification information, not only can the target transmission signal have an identification to provide a reference for subsequent tracing, but it can also improve the transmission reference during twisted pair transmission, avoid repeated transmission or missed transmission of the target transmission signal, and provide protection for twisted pair transmission.

[0078] In an embodiment provided by the present invention, when configuring nodes according to a signal processing scheme, the number of nodes is determined according to the signal processing scheme, and the nodes are started according to the number of nodes to determine the target node. Then, a signal dispatch strategy is extracted for the signal processing scheme, the signal dispatch strategy is analyzed, the dispatch order is determined, and the target signal identification feature information is determined for the target node in combination with the dispatch order. At the same time, the node feature information of the target node is obtained, and the node feature information is combined with the target signal identification feature information to determine the target node identification information.

[0079] In the above technical solution, the signal dispatching strategy is a solution strategy for signal processing at the target node, for example: the target nodes extract and process the target digital signals in turn; the target nodes extract and process the target digital signals when some of them are on leave, and so on.

[0080] In the above technical scheme, when extracting the signal to be processed for the target digital signal through the target node in combination with the signal processing scheme, the target node can only determine the target processing signal characteristics in combination with the signal processing scheme and then extract the target object for the target digital signal according to the target processing signal characteristics to obtain the signal to be processed.

[0081] The above technical solution combines the signal processing solution to extract the signal to be processed for the target digital signal through the target node, so that the target node can only obtain the signal to be processed according to the signal processing solution. This can not only ensure the processing effect of the first signal processing, but also ensure that the target node performs the first signal processing on the target digital signal in an orderly manner, reduce time waste, and improve the efficiency of the first signal processing.

[0082] like Figure 4 As shown, in one embodiment provided by the present invention, a target transmission signal is transmitted to a second transceiver through a twisted pair using a multi-channel bidirectional mutual transmission method, including:

[0083] B1, sending the target transmission signal from the first transceiver end based on the twisted pair;

[0084] B2. Propagate signals in twisted pair cables in a multi-channel mutual transmission mode, analyze signal propagation phenomena, and obtain propagation reflection signals based on self-inductance effect and mutual inductance effect;

[0085] B3. Analyze and determine whether the target transmission signal needs to be enhanced based on the propagation reflection signal, and obtain the analysis and determination result;

[0086] B4. Perform enhancement processing on the target transmission signal according to the analysis and judgment results to obtain a target transmission processing signal;

[0087] B5. Forward the target transmission processing signal to the second transceiver.

[0088] In the above technical solution, when signal propagation is performed in a twisted pair according to a multi-channel mutual transmission mode, dynamic management is performed on the multi-channel bidirectional mutual transmission twisted pair so that the target transmission signal is transmitted in the twisted pair.

[0089] In the above technical solution, if the analysis and judgment result is that the target transmission signal does not need enhanced processing, the target transmission signal is directly forwarded to the second transceiver.

[0090] In the above technical solution, if the analysis and judgment result is that the target transmission signal needs enhanced processing, the target transmission signal is enhanced to obtain a target transmission processing signal, and then the target transmission processing signal is forwarded to the second transceiver.

[0091] In the above technical solution, the enhancement processing is the signal amplification processing.

[0092] The above technical solution improves transmission performance by transmitting signals in twisted pair cables in a multi-channel mutual transmission manner. At the same time, by analyzing signal propagation phenomena, it clarifies the influence of factors such as electromagnetic interference and line loss on the target transmission signal during the transmission process of twisted pair cables. By enhancing processing, it reduces signal attenuation, distortion and noise, thereby improving the quality of twisted pair signal transmission.

[0093] In one embodiment provided by the present invention, when forwarding the target transmission processing signal to the second transceiver, calibration optimization is also performed on the target transmission processing signal, including:

[0094] Acquiring a calibration signal based on a target transmission processing signal;

[0095] Different equalization processes are applied to the calibration signal to obtain multiple calibration processed signals;

[0096] Perform compensation analysis based on the calibration processing signal combined with the calibration signal, and optimize the target transmission processing signal according to the compensation analysis data until the calibration processing signal and the calibration signal are consistent, thereby obtaining the target transmission processing optimization signal;

[0097] Separating the delay difference signal based on the target transmission processing optimization signal to obtain the delay difference signal;

[0098] According to the delay difference signal, the signal delay control adjustment is performed in the process of optimizing the signal transmission during the target transmission processing, and then the signal is output at the second transceiver end to obtain a received signal.

[0099] In the above technical solution, if the calibration processing signal and the calibration signal are not consistent, the target transmission processing signal is continuously optimized until the calibration processing signal and the calibration signal are consistent, thereby obtaining a target transmission processing optimized signal.

[0100] The above technical solution adjusts the target transmission processing signal by performing compensation analysis based on the calibration processing signal combined with the calibration signal, so that the target transmission processing signal has high consistency before and after transmission, optimizes the quality of the signal to be transmitted to the greatest extent, and provides guarantee for the transmission of the target transmission processing optimization signal. In addition, by adjusting the signal delay control during the transmission of the target transmission processing optimization signal based on the delay difference signal, the delay is reduced, so that the twisted pair extender can realize real-time forwarding of digital signals, and the target device can play according to the digital signal in real time and synchronously.

[0101] like Figure 5 As shown, in one embodiment provided by the present invention, the second transceiver uses multiple nodes to perform second signal processing on the received signal, including:

[0102] C1. Acquire the status information of the node at the second transceiver end to obtain the node status information;

[0103] C2, distribute the received signal to the target node in combination with the node status information;

[0104] C3. In the target node, receive processing is performed on the received signal to obtain a received processed signal, and device information of the target device is obtained at the same time;

[0105] C4. Perform signal adjustment on the received processing signal in combination with the device information of the target device to obtain the target received signal;

[0106] C5. Forward the target received signal to the target device for playback.

[0107] In the above technical scheme, the received signal is distributed to the target node in combination with the node status information, including: analyzing whether there are idle nodes according to the node status information, when there are idle nodes, determining the number of idle nodes, if there is only one idle node, directly distributing the received signal to the idle node, if there are multiple idle nodes, selecting any one as the target node, and distributing the received signal to the target node; when there are no idle nodes, the processing time is estimated according to the node status information to obtain the node processing waiting time, the minimum value is screened according to the node processing waiting time, and then the received signal is distributed to the node corresponding to the minimum value of the point processing waiting time to form a node waiting processing queue, and the node waiting processing queue is also monitored in real time, and whether the node waiting processing queue is balanced is analyzed. If it is not balanced, whether the difference between the node waiting processing queues exceeds the preset value is analyzed. When the difference between the node waiting processing queues exceeds the preset value, the node waiting processing queues are balanced and adjusted to reduce the difference between the node waiting processing queues.

[0108] The above-mentioned technical scheme distributes the received signal to the target node by combining the node status information so that the second transceiver can process the received signal through the node in time when the received signal is obtained, thereby avoiding the impact of the received signal on the playback of the target device due to untimely processing of the received signal at the second transceiver. In addition, by combining the node status information to distribute the received signal to the target node, dynamic management of the received signal is realized, avoiding the received signal waiting for a long time for the node to process, and also avoiding the phenomenon of uneven node processing, so that all nodes can reasonably process the received signal.

[0109] In one embodiment of the present invention, receiving and processing a received signal includes:

[0110] Perform a preliminary analysis on the received signal to determine whether the received signal has any abnormal signal reception phenomenon, and obtain a preliminary analysis and judgment result;

[0111] When the preliminary analysis and judgment result shows that abnormal signal reception occurs, an abnormal reminder is given for signal reception; when the preliminary analysis and judgment result shows that no abnormal signal reception occurs, signal preprocessing is performed on the received signal to obtain a received processed signal.

[0112] In the above technical solution, signal preprocessing includes: filtering, noise reduction, gain adjustment, nonlinear distortion elimination, etc.

[0113] In the above technical solution, abnormal signal reception phenomena include: signal interruption, repeated cycles, etc.

[0114] The above technical solution clarifies whether there is any abnormal signal reception phenomenon in the received signal through preliminary analysis, so that timely reminders can be given when the received signal has abnormal signal reception phenomenon, so that relevant personnel can deal with the abnormal signal reception phenomenon in time to avoid excessive impact on the real-time playback of the digital signal in the target device. In addition, by performing signal preprocessing on the received signal, the accuracy and reliability of the received signal are improved, so that the target device can better play the received signal, providing guarantee for the playback effect of the target device.

[0115] In one embodiment of the present invention, signal adjustment is performed on a received and processed signal in combination with device information of a target device, including:

[0116] Determine whether the received and processed signal can be directly played on the target device according to the device information, and obtain a first determination result;

[0117] Perform analysis and adjustment based on the first judgment result; when the first judgment result is that the received processed signal can be directly played on the target device, directly forward the received processed signal to the target device for playback; when the first judgment result is that the received processed signal cannot be directly played on the target device, analyze the received processed signal in combination with the device information to determine the adjustment type, and perform signal adjustment on the received processed signal according to the adjustment type to obtain the target received signal, thereby forwarding the target received signal to the target device for playback.

[0118] In the above technical solution, the adjustment types include: format adjustment and version adjustment.

[0119] The above technical solution adjusts the received processing signal by combining the device information of the target device, thereby ensuring that the target received signal can be played on the target device, and avoiding the incompatibility of the received signal with the target device, resulting in the target device being unable to play.

[0120] like Figure 6 As shown, an embodiment of the present invention provides a signal processing method, which performs signal processing based on the twisted pair extender described in any of the above embodiments, including:

[0121] Step 1: acquiring a digital signal at a first transceiver end, and performing first signal processing on the digital signal using multiple nodes to obtain a target transmission signal;

[0122] Step 2: transmitting the target transmission signal from the first transceiver end to the second transceiver end through the twisted pair cable;

[0123] Step 3: receiving the target transmission signal at the second transceiver to obtain a received signal, and performing second signal processing on the received signal using multiple nodes to obtain a target received signal;

[0124] Step 4: forward the target received signal from the second transceiver to the target device for playback.

[0125] The above technical solution can not only eliminate the limitation of transmission distance through the twisted pair extender, realize multi-channel two-way mutual transmission and high-quality transmission of long-distance signals, reduce the loss of signals during transmission, ensure the quality of received signals, improve transmission performance, but also reduce time consumption, so that digital signals can be played in the target device in time, and realize real-time playback of video or audio signals. Two-way mutual transmission is realized through twisted pair, while reducing the interference of signal transmission, reducing the loss of signals during transmission, ensuring the quality of received signals, so that the target device can play high-quality video or audio signals; the first transceiver and the second transceiver use multiple nodes for signal processing, effectively improving the efficiency of signal processing, reducing the time efficiency, so that the digital signal can reach the target device in a shorter time, and then realize the real-time playback of video or audio signals.
