Description
本申请涉及通信技术领域,尤其涉及一种组网方法及组网系统。
目前,为实现文字内容的数字化显示,通常采用触摸输入的方式在组网系统上对文字内容进行手写输入,例如,通过手写笔在手写板上进行书写时,手写板将真实笔迹转化成电子笔迹数据并将电子笔迹发送至终端设备(例如,手机)以进行显示。
在一些特定的场合下(例如,课堂或者商务会议时),需要若干手写板均与终端设备进行网络连接,以实现每个手写板的笔迹数据同步在终端设备进行显示的效果。为了实现多个手写板能够顺利的进行数据传输,通常将若干手写板进行分组,且每一组手写板与一个路由器进行连接,进而使得每个手写板生成的笔迹数据通过对应的路由器发送至所述终端设备。然而,当手写板的数量较多时,即使对手写板进行了分组,由于每一组内的手写板共用一个路由器而导致每个手写板分配的传输时间较少,从而导致数据实时传输能力较差,数据丢失的情况发生,影响用户的使用。

本申请的组网方法及组网系统,由于在组网时每个汇聚节点从所述若干数据生成节点中选取第一预设数量的数据生成节点作为中继节点,并建立与所述第一预设数量的中继节点之间的第二级网络连接。每个中继节点从剩余的若干数据生成节点中选取第二预设数量的数据生成节点,并与所述第二预设数量的数据生成节点建立第三极网络连接,即,将若干数据生成节点进行分级组网,相对于现有技术中的组网方式增加了每个数据生成节点的有效传输时间,同时并减少了每个数据生成节点的等待时间,从而提高了数据传输效率。此外,还可以减少汇聚节点的使用量,进而在提高传输效率的同时降低了组网成本。
为了更清楚地说明本申请实施例中的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

图4为本申请另一实施例中的组网方法的流程图。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
需要说明的是,在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
请参阅图1,图1为本申请一实施例公开的组网系统100的架构示意图。所述组网系统100包括若干数据生成节点10、多个汇聚节点20以及终端设备30。其中,所述若干数据生成节点10用于生成数据信息。所述多个汇聚节点20用于中继传输,即,所述多个汇聚节点20用于接收所述数据信息并将所述数据信息发送至所述终端设备30。所述终端设备30用于对接收到的数据信息进行处理并进行显示。
请再参阅图2,图2为本申请一实施例公开的组网系统100的组网示意图。在组网过程中,所述终端设备30用于建立所述终端设备30与所述多个汇聚节点20之间的第一级网络连接。即,所述终端设备30作为所述组网系统100的第一级网络节点,所述多个汇聚节点20作为所述组网系统100的第二级网络节点。每个汇聚节点20从所述若干数据生成节点10中选取第一预设数量的数据生成节点10作为对应的中继节点40,并建立每个汇聚节点20与对应的所述第一预设数量的中继节点40之间的第二级网络连接。即,所述多个汇聚节点作为所述组网系统100的第三级网络节点。每个中继节点40从剩余的若 干数据生成节点10中选取第二预设数量的数据生成节点10,并与对应的所述第二预设数量的数据生成节点10建立第三极网络连接。其中,每个中继节点20与建立第三网络连接的所述第二预设数量的数据生成节点10形成对应的网络连接组。
在一些实施方式中,每个数据生成节点10用于响应书写操作而生成笔迹数据。每一网络连接组中数据生成节点10将生成的笔迹数据发送至相应网络连接组中的中继节点40,再由中继节点40将所述笔迹数据传输至汇聚节点20,然后通过汇聚节点20发送至终端设备30进行显示。在本实施方式中,所述数据生成节点10与中继节点40为手写板,所述汇聚节点20为路由器。亦即,每一网络连接组中数据生成节点10的手写板将生成的笔迹数据发送至相应网络连接组中的作为中继节点40的手写板,再由作为中继节点40的手写板将所述笔迹数据传输至作为汇聚节点20的路由器,然后通过作为汇聚节点20的路由器发送至终端设备30进行显示。
在一些实施方式中,中继节点40将所述笔迹数据传输至汇聚节点20,具体包括:所述中继节点40将接收到的笔迹数据及自身生成的笔迹数据一并发送至所述汇聚节点20。如此,可以提高每个手写板的传输效率。
例如,现有的技术中的组网方式,当n个手写板同时连接到一个路由器时,一个路由器需要维护n个手写板的数据连接,则在T(ms)时间段内,每个手写板平均分配到的时间片则只有T/n(ms),同时也意味着有(n-1)/n*T(ms)的时间间隔内路由不能处理某一个手写板的数据。那么当n越大,对每一个手写板的处理能力越弱,数据实时传输能力越弱丢失率也越高,严重影响了蓝牙路由的负载能力。具体地,若一个教室有60个手写板,且使用6个路由器,即,每个路由器连接10个手写板,则每个手写板只能被分配到0.1s的数据传输时间,并且会在0.9s内产生的数据点无法被展示,这样如果个别手写板数据量较大时,则导致数据丢失严重。而采用本申请中的技术方案,在组网时,若每个路由器从手写板中选取3个作为中继节点40,即每个路由器连接3个手写板以建立所述第二级网络连接,每个手写板再分别连接3个手写板以建立第三级网络连接,相当于每个路由器连接12个手写板,如此,同样在存在60个手写板的教室中,只需要5个路由器即可,而此时每个手写板能够分配到0.333s的 数据传输时间,等待时间为0.667s,如此,提高了每个手写板的数据传输时间的同时减少了每个手写板的等待时间,从而提高了数据传输的效率,避免了数据丢失的情况发生。此外,还减少了路由器的使用数量,降低了组网成本。
因此,本申请所提供的组网系统100,由于在组网时每个汇聚节点20从所述若干数据生成节点10中选取第一预设数量的数据生成节点10作为中继节点40,并建立与所述第一预设数量的中继节点40之间的第二级网络连接。每个中继节点40从剩余的若干数据生成节点10中选取第二预设数量的数据生成节点10,并与所述第二预设数量的数据生成节点10建立第三极网络连接,即,将若干数据生成节点10进行分级组网,相对于现有技术中的组网方式增加了每个数据生成节点10的有效传输时间,同时并减少了每个数据生成节点10的等待时间,从而提高了数据传输效率。此外,还可以减少汇聚节点20的使用量,进而在提高传输效率的同时降低了组网成本。
在一些实施方式中,所述第一预设数量和所述第二预设数量由汇聚节点30的负载量确定,具体地,所述第一预设数量和所述第一预设数量与所述第二预设数量的乘积的和小于等于所述汇聚节点的最大负载量。其中,所述第一预设数量和所述第二预设数量均为正整数。优选的,所述第一预设数量和所述第二预设数量相等,如此,每个数据生成节点10的数据分配时间和等待时间相同,且能最大化每个数据生成节点10的传输效率。
在一些实施方式中,所述终端设备30建立所述终端设备30与所述多个汇聚节点20之间的第一级网络连接,包括:所述终端设备30搜索所述汇聚节点20的网络信号,并当搜索到所述汇聚节点20的网络信号时,与所述汇聚节点20建立所述第一级网络连接。具体地,当搜索到所述汇聚节点20的网络信号时,所述终端设备30发送入网请求至多个汇聚节点20,当汇聚节点20接收到入网请求时,产生同意入网请求的响应数据,当终端设备30接收到同意入网请求的响应数据后即可建立终端设备20与多个汇聚节点20之间的第一级网络连接。
在一些实施方式中,所述每个汇聚节点20从所述若干数据生成节点10中选取第一预设数量的数据生成节点10作为对应的中继节点40,包括:所述每个汇聚节点20搜索所述若干数据生成节点10的网络信号,并确定所述数据 生成节点10的网络信号强度由强到弱排序的排序靠前的所述第一预设数量的数据生成节点10为所述对应的中继节点40。在本实施方式中,每个汇聚节点20搜索到若干数据生成节点10的网络信号时,会对信号强度由强到若进行排序,并选取信号强度排序靠前的第一预设数量的数据生成节点10作为所述中继节点40。可以理解,信号强度一般与距离有关,即,距离越近,信号强度越强。当每个数据生成节点10的位置和所述汇聚节点20的位置确定后,他们之间的距离也是确定的,因此,每个汇聚节点20会把距离其相对较近的多个数据生成节点10选取作为中继节点40。其中,与中继节点40建立连接的方式与前述实施例中的第一网络的建立方式相同,在此不再赘述。
在一些实施方式中,所述每个中继节点40从剩余的若干数据生成节点10中选取第二预设数量的数据生成节点10,包括:所述每个中继节点40搜索剩余的未作为中继节点40的若干数据生成节点10的网络信号,并按照网络信号的强度由强到若排序选取排序靠前的所述第二预设数量的数据生成节点10建立所述第三网络连接。该实施例中的关于信号强度相关的说明及第三网络建立的方式可参前述实施例。
在一些实施方式中,所述与对应的所述第二预设数量的数据生成节点10建立第三级网络连接,包括:所述每个中继节点40向对应的所述第二预设数量的数据生成节点10发送入网请求,并在接收到任一数据生成节点10的同意入网请求的响应数据后建立与所述数据生成节点10的第三网络连接。在本实施方式中,当收到所述入网请求的数据生成节点10为已建立网络连接的数据生成节点10时,所述已建立网络连接的数据生成节点10忽略所述入网请求,而不产生所述同意入网请求的响应数据。
需要说明的是,在该实施方式中,由于某些数据生成节点10已被选做为中继节点40,但在网络搜索的过程中,其网路信号的强度较强,且排名较为靠前,此时,若其接收到入网请求,则忽略不响应,即已建立网络连接的数据生成节点10在接收到所述入网请求时,不产生所述同意入网请求的响应数据。此时,中继节点40将不会收到同意入网请求的响应数据,进而不会与其建立网络连接,将会再向信号强度次之的数据生成节点10发送入网请求。
此外,所述第一级网络、第二级网络及第三级网络包括但不限于蓝牙网络、 WiFi网络、局域网、互联网等。在组网之前,需要将终端设备30、多个汇聚节点20级若干手写板10的网络端口全部打开。所述终端设备30、所述多个汇聚节点20和所述若干数据生成节点10,均通过网络端口来搜索信号、发送入网请求或者发出相应的响应数据。
请再参阅图3,其为本申请一实施例提供的组网方法的流程图。所述组网方法应用于组网系统100中,所述组网系统100包括:用于生成数据信息的若干数据生成节点10、用于中继传输的多个汇聚节点20以及用于进行数据显示的终端设备30。所述组网方法包括如下步骤:
步骤S31,建立所述终端设备30与所述多个汇聚节点20之间的第一级网络连接。
在一些实施方式中,所述建立所述终端设备30与所述多个汇聚节点20之间的第一级网络连接,包括:所述终端设备30搜索所述汇聚节点的网络信号,并当搜索到所述汇聚节点20的网络信号时,与所述汇聚节点20建立所述第一级网络连接。
具体地,当搜索到所述汇聚节点20的网络信号时,所述终端设备30发送入网请求至多个汇聚节点20,当汇聚节点20接收到入网请求时,产生同意入网请求的响应数据,当终端设备30接收到到同意入网请求的响应数据后即可建立终端设备20与多个汇聚节点20之间的第一级网络连接。
步骤S32,每个汇聚节点20从所述若干数据生成节点10中选取第一预设数量的数据生成节点10作为对应的中继节点40,并建立每个汇聚节点20与对应的所述第一预设数量的中继节点40之间的第二级网络连接。
在一些实施方式中,所述每个汇聚节点20从所述若干数据生成节点10中选取第一预设数量的数据生成节点10作为对应的中继节点40,包括:所述每个汇聚节点20搜索所述若干数据生成节点10的网络信号,并确定网络信号强度由强到弱排序的排序靠前的所述第一预设数量的数据生成节点10为所述对应的中继节点40。
步骤S33,每个中继节点40从剩余的若干数据生成节点10中选取第二预设数量的数据生成节点10,并与对应的所述第二预设数量的数据生成节点10建立第三级网络连接;其中,每个中继节点40与建立第三网络连接的所述第 二预设数量的数据生成节点10形成对应的网络连接组。

所述与对应的所述第二预设数量的数据生成节点10建立第三级网络连接,包括:所述每个中继节点40向对应的所述第二预设数量的数据生成节点10发送入网请求,并在接收到任一数据生成节点10同意入网请求的响应数据后建立与所述数据生成节点10的第三网络连接。在本实施方式中,当收到所述所述入网请求的数据生成节点10为已建立网络连接的数据生成节点10时,所述已建立网络连接的数据生成节点10忽略所述入网请求,而不产生所述同意入网请求的响应数据。
需要说明的是,在该实施方式中,由于某些数据生成节点10已被选做为中继节点40,但在网络搜索的过程中,其网路信号的强度较强,且排名较为靠前,此时,若其接收到入网请求,则忽略不响应,即已建立网络连接的数据生成节点在接收到所述入网请求时,不产生所述同意入网请求的响应数据。此时,中继节点40将不会收到同意入网请求的响应数据,进而不会与其建立网络连接,将会再向信号强度次之的数据生成节点发送入网请求。
本申请所提供的组网方法,由于在组网时每个汇聚节点20从所述若干数据生成节点10中选取第一预设数量的数据生成节点10作为中继节点40,并建立与所述第一预设数量的中继节点40之间的第二级网络连接。每个中继节点40从剩余的若干数据生成节点10中选取第二预设数量的数据生成节点10,并与所述第二预设数量的数据生成节点10建立第三极网络连接,即,将若干数据生成节点10进行分级组网,相对于现有技术中的组网方式增加了每个数据生成节点10的有效传输时间,同时并减少了每个数据生成节点10的等待时间,从而提高了数据传输效率。此外,还可以减少汇聚节点20的使用量,进而在提高传输效率的同时降低了组网成本。
在一些实施方式中,所述第一预设数量和所述第二预设数量由汇聚节点 30的负载量确定,具体地,所述第一预设数量和所述第一预设数量与所述第二预设数量的乘积的和小于等于所述汇聚节点20的最大负载量。例如,假设第一预设数量为x,第二预设数量为y,汇聚节点20的最大负载量为z,则满足公式:x+x*y≤z。其中,所述第一预设数量和所述第二预设数量均为正整数。优选的,所述第一预设数量和所述第二预设数量相等,如此,每个数据生成节点10的数据分配时间和等待时间相同,且能最大化每个数据生成节点10的传输效率。
请再参阅图4,在一些实施方式中,每个数据生成节点10用于响应书写操作而生成笔迹数据。所述组网方法较之图3中的组网方法在步骤S33之后还包括如下步骤:

其中,在一些实施方式中,所述数据生成节点10为手写板,所述汇聚节点20为路由器。
