背景技术Background technique

依据IEEE 802.3cg标准规范，现有的物理层冲突避免(physical layercollision avoidance：PLCA)多点网络(multidrop network)只支持10Mbps的传输速度。如果要提升该传输速度，则须考虑通道效应以及克服符号间干扰(Inter symbolinterference：ISI)。通道效应与符号间干扰对接收信号的影响可通过对接收端的通道均衡器进行训练来降低；然而，本技术领域的标准规范(例如：IEEE 802.3bw与IEEE 802.3bp)仅定义了点对点传输架构下的通道均衡器系数训练方式，而此方式无法应用于多点网络系统。According to the IEEE 802.3cg standard specification, the existing physical layer collision avoidance (PLCA) multidrop network only supports a transmission speed of 10 Mbps. If the transmission speed is to be increased, channel effects and inter-symbol interference (ISI) must be considered. The influence of channel effect and intersymbol interference on the received signal can be reduced by training the channel equalizer at the receiving end; however, standard specifications in this technical field (for example: IEEE 802.3bw and IEEE 802.3bp) only define channel equalizer coefficient training method, which cannot be applied to multi-point network systems.

图1为根据本发明示出的多点网络系统的一实施例。图1的多点网络系统100包括N个网络装置(即：N个节点)，该N为大于或等于二的整数。该N个网络装置通过实体传输媒介102(例如：双绞缆线(twisted pair cable)或光缆线(optical cable))交换数据，并包括一主控装置110与多个从属装置120。该N个网络装置中的每一个具有一辨识码(identification code：IDC)，以作为该多点网络系统100中的身份辨识信息，因此，该N个网络装置共具有N个辨识码(例如：0,1,2,…,(N-2),(N-1))。该N个网络装置在每一轮的数据传输中依据该N个辨识码的顺序循序获得在该多点网络系统中的传输机会；由于获得传输机会的技术不在本发明的讨论范围内，也不会对本发明的实施构成限制，因此该技术的说明在此省略。本领域中具有普通知识的技术人员可参考美国专利公开案(公开号：US2019/0230705 A1)以了解该N个网络装置如何依据该N个辨识码循序获得在该多点网络系统中的传输机会。FIG. 1 is an embodiment of a multi-point network system according to the present invention. Themulti-point network system 100 in FIG. 1 includes N network devices (ie: N nodes), where N is an integer greater than or equal to two. The N network devices exchange data through a physical transmission medium 102 (eg, twisted pair cable or optical cable), and include amaster device 110 and a plurality ofslave devices 120 . Each of the N network devices has an identification code (identification code: IDC) as identification information in themulti-point network system 100, therefore, the N network devices have N identification codes (for example: 0,1,2,...,(N-2),(N-1)). In each round of data transmission, the N network devices sequentially obtain transmission opportunities in the multi-point network system according to the order of the N identification codes; since the technology for obtaining transmission opportunities is not within the scope of the present invention, nor This would constitute a limitation on the implementation of the present invention, so the description of this technique is omitted here. Those skilled in the art can refer to the US patent publication (publication number: US2019/0230705 A1) to understand how the N network devices sequentially obtain transmission opportunities in the multi-point network system according to the N identification codes .

请参阅图1。本实施例中，该N个网络装置在一同步阶段进行时区同步；该N个网络装置中的K个网络装置在一训练阶段进行均衡器系数训练，该K为大于或等于二但不大于该N的整数；以及该N个网络装置在一数据传输阶段依据该N个辨识码循序获得传输机会；图2示出了同步阶段210、训练阶段220与数据传输阶段230的顺序。如果该K不等于该N，那么该N个网络装置中除了包括该K个网络装置外，也包括其余(N-K)个网络装置，其中该(N-K)个网络装置在该训练阶段不进行该均衡器系数训练，且该(N-K)个网络装置为无法识别且不回应该训练通知的装置。值得注意的是，该K个网络装置包括主控装置110与(K-1)个从属装置120，且该K个网络装置中的每一个包括一通道均衡器，该通道均衡器用来在该训练阶段接受训练以及在该数据传输阶段处理数据。See Figure 1. In this embodiment, the N network devices perform time zone synchronization in a synchronization stage; K network devices in the N network devices perform equalizer coefficient training in a training stage, and the K is greater than or equal to two but not greater than the N is an integer; and the N network devices sequentially obtain transmission opportunities according to the N identification codes in a data transmission phase; FIG. 2 shows the sequence of thesynchronization phase 210 , thetraining phase 220 and thedata transmission phase 230 . If the K is not equal to the N, then the N network devices include not only the K network devices, but also other (N-K) network devices, wherein the (N-K) network devices do not perform the equalization during the training phase device coefficient training, and the (N-K) network devices are devices that cannot be identified and do not respond to the training notification. It should be noted that the K network devices include amaster device 110 and (K-1)slave devices 120, and each of the K network devices includes a channel equalizer, which is used for training stage receives training and processes data in the data transfer stage.

在该同步阶段，在该N个网络装置的每一轮的数据传输开始前，主控装置110传送一信标(beacon)给所有从属装置120，以同步主控装置110的时区与该多个从属装置120的时区；上述同步作业通过已知/自行开发的技术来实现(例如：每个网络装置依据该信标重置计数器/计时器)。在该训练阶段，主控装置110发出一训练通知，以通知该(K-1)个从属装置120进入该训练阶段。主控装置110在发出该训练通知后，进行该均衡器系数训练；该(K-1)个从属装置120在收到该训练通知后，进行该均衡器系数训练。在M轮该均衡器系数训练(M rounds of the equalizer coefficient training)(简称M轮训练)后，主控装置110传送该信标给所有从属装置120，以开始该数据传输阶段，其中该数字M可以是固定或不固定的正整数(fixed/unfixed positive integer)。In the synchronization phase, before each round of data transmission of the N network devices starts, themaster device 110 sends a beacon to allslave devices 120 to synchronize the time zone of themaster device 110 with the multiple The time zone of theslave device 120; the above-mentioned synchronization operation is realized by known/self-developed techniques (eg, each network device resets the counter/timer according to the beacon). During the training phase, themaster device 110 sends a training notification to notify the (K−1)slave devices 120 to enter the training phase. Themaster device 110 performs the equalizer coefficient training after sending the training notification; the (K−1)slave devices 120 perform the equalizer coefficient training after receiving the training notification. After M rounds of the equalizer coefficient training (M rounds of the equalizer coefficient training) (referred to as M rounds of training), themaster device 110 sends the beacon to allslave devices 120 to start the data transmission phase, wherein the number M Can be a fixed or unfixed positive integer (fixed/unfixed positive integer).

在一实施例中，该数字M为一固定的正整数，这意味着无论该K个网络装置中是否有任何装置尚未完成该均衡器系数训练，在该M轮训练后，主控装置110会传送该信标给所有从属装置120，以开始该数据传输阶段。In one embodiment, the number M is a fixed positive integer, which means that no matter whether any device among the K network devices has not completed the equalizer coefficient training, after the M rounds of training, themain control device 110 will Send the beacon to allslave devices 120 to start the data transfer phase.

在另一实施例中，该数字M为一非固定的正整数。该(K-1)个从属装置120的每一个在该M轮训练的至少其中一轮中发出一训练完成信号，以表示它已完成该均衡器系数训练。该K个网络装置(即：该(K-1)个从属装置120与主控装置110)中最晚完成该均衡器系数训练的那一个在该M轮训练的一第M轮训练(即：最后一轮训练)中完成该训练；换句话说，该M的值取决于该K个网络装置何时全部完成该训练。在主控装置110完成该均衡器系数训练且收到该(K-1)个从属装置120中的每一个的该训练完成信号后，主控装置110传送该信标给所有从属装置120，以开始该数据传输阶段。In another embodiment, the number M is a non-fixed positive integer. Each of the (K−1)slave devices 120 sends out a training completion signal in at least one of the M training rounds to indicate that it has completed the equalizer coefficient training. Among the K network devices (ie: the (K-1)slave devices 120 and the master control device 110 ), the one that completes the equalizer coefficient training at the latest is in an M-th round of training in the M rounds of training (ie: The training is completed in the last round of training); in other words, the value of M depends on when all the K network devices complete the training. After themaster device 110 completes the equalizer coefficient training and receives the training completion signal from each of the (K-1)slave devices 120, themaster device 110 sends the beacon to allslave devices 120 to Start the data transfer phase.

请参阅图1-2。在主控装置110发出该训练通知后，该K个网络装置进行该M轮训练。该K个网络装置在该M轮训练的一第X轮训练中循序(例如：依据该K个网络装置中的K个辨识码的顺序)发出K个训练信号，该X为不大于该M的正整数。该K个网络装置中的每一个在该第X轮训练中循序收到来自其它(K-1)个网络装置的(K-1)个训练信号，并依据该(K-1)个训练信号以及该(K-1)个训练信号的原始图样(original pattern)进行该均衡器系数训练，该均衡器系数训练可通过已知的技术(例如：IEEE 802.3bw标准规范及/或IEEE 802.3bp标准规范)或自行开发的技术来实现。举例而言，主控装置110循序接收所有从属装置120的训练信号；每收到一从属装置120的训练信号，主控装置110就比较该训练信号以及该训练信号的原始图样，以依据该比较结果调整其通道均衡器的系数，并储存该/该多个系数用于接收此从属装置120的信号。每个从属装置120的均衡器系数训练的方式可依据上述说明类推得出。在一实施例中，该K个训练信号在失真前是相同的，该K个训练信号的原始图样也是相同的，并事先将该K个训练信号及其原始图样储存于该K个网络装置中以供比对；然而这并不会对本发明的实施构成限制。See Figure 1-2. After themain control device 110 sends the training notification, the K network devices perform the M rounds of training. The K network devices send K training signals sequentially (for example: according to the order of the K identification codes in the K network devices) in the X-th round of the M rounds of training, and the X is not greater than the M positive integer. Each of the K network devices sequentially receives (K-1) training signals from other (K-1) network devices in the X-th round of training, and according to the (K-1) training signals and the original pattern (original pattern) of the (K-1) training signals to perform the equalizer coefficient training, the equalizer coefficient training can be performed through known techniques (for example: IEEE 802.3bw standard specification and/or IEEE 802.3bp standard specification) or self-developed technology to achieve. For example, themaster control device 110 receives the training signals of allslave devices 120 sequentially; each time a training signal of aslave device 120 is received, themaster control device 110 compares the training signal with the original pattern of the training signal, so as to As a result, the coefficients of its channel equalizer are adjusted, and the/the coefficients are stored for receiving the signal of theslave device 120 . The manner of training the equalizer coefficients of eachslave device 120 can be derived by analogy from the above description. In one embodiment, the K training signals are the same before distortion, and the original patterns of the K training signals are also the same, and the K training signals and their original patterns are stored in the K network devices in advance For comparison; however, this does not limit the implementation of the present invention.

请参阅图1-2。由于传输环境可能随着时间改变，该K个网络装置中的每一个可于该数据传输阶段要求回到该训练阶段，以重做该均衡器系数训练。在一实施例中，主控装置110在该数据传输阶段重新发出该训练通知，以令该K个网络装置回到该训练阶段。在一实施例中，该(K-1)个从属装置120中的一个在该数据传输阶段发出一重新训练要求，以要求主控装置110发出该训练通知，从而令该K个网络装置回到该训练阶段。在一实施例中，主控装置110在某一轮的数据传输中收到该重新训练要求，并在该轮的数据传输结束后发出该训练通知。在一实施例中，该(K-1)个从属装置120中的一个在某一轮的数据传输中发出该重新训练要求，其余(K-2)个从属装置120在收到该重新训练要求后保持静默(silent)，从而主控装置110可于收到该重新训练要求后，快速地在该轮的数据传输结束前发出该训练通知。See Figure 1-2. Since the transmission environment may change over time, each of the K network devices may request to go back to the training phase during the data transmission phase to redo the equalizer coefficient training. In one embodiment, themain control device 110 re-sends the training notification during the data transmission phase, so as to make the K network devices return to the training phase. In one embodiment, one of the (K-1)slave devices 120 sends a retraining request during the data transmission phase, so as to request themaster device 110 to send the training notification, so that the K network devices return to the training phase. In one embodiment, themain control device 110 receives the retraining request during a certain round of data transmission, and sends the training notification after the end of the round of data transmission. In one embodiment, one of the (K-1)slave devices 120 sends out the retraining request during a certain round of data transmission, and the remaining (K-2)slave devices 120 receive the retraining request Then keep silent (silent), so that after receiving the retraining request, themain control device 110 can quickly send out the training notification before the end of the round of data transmission.

图1中的多点网络系统100中的每个网络装置(即：主控装置110或任一从属装置120)可独立地被实施。由于本领域中具有普通知识的技术人员能够参考图1中对多点网络系统100的说明来了解多点网络系统100中每个网络装置的实施细节与变化，重复且冗余的说明在此予以省略。Each network device (ie, themaster device 110 or any slave device 120 ) in themultipoint network system 100 in FIG. 1 can be implemented independently. Since those skilled in the art can refer to the description of themultipoint network system 100 in FIG. 1 to understand the implementation details and changes of each network device in themultipoint network system 100, repeated and redundant descriptions are given here. omitted.
