本申请涉及数据传输技术领域，尤其涉及一种带宽划分方法、装置、设备及计算机可读存储介质。
现有工业以太网总线中，如PROFINET、EtherCAT、EtherNetIP协议都会对总线的带宽进行划分，一般划分为实时的数据和非实时的数据两大类，实时数据也称PDO数据，也即过程数据，主要应用于控制相关的数据传输，具备周期性和确定性。而非实时数据应用于多种场合，如参数的配置、固件的升级、数据的连续采集、诊断等，非实时数据对实时性能的要求较低。在网络系统正常工作状态下，链路上会存在实时数据和非实时数据，其中非实时数据不能影响实时数据的周期性和确定性，这一点现有主站都会自行保证。对于非实时数据，可以应用于多种服务，虽然这类服务对数据的实时性没有太高的要求，但是对于数据的传输带宽，业务应用的体验会有一定的要求。
就目前主流的工业以太网协议而言，都不会去做进一步的带宽划分，导致多个从站设备在需要被同时调试和监视时，业务产生的数据与链路上允许的带宽不匹配带来使用上缺陷，如非实时数据的通道会用于一些生产者消费者模型的业务，比如固定周期采样的数据上报，触发式的参数访问，多个节点的数据上报等非实时业务同时进行会容易造成部分业务数据的丢失、业务数据回复时间长等缺陷，也就是说现有技术中非实时数据带宽分配不合理，导致业务数据分配不合理。
本申请的主要目的在于提供一种带宽划分方法、装置、设备及计算机可读存储介质，旨在解决非实时数据带宽分配不合理，导致业务数据分配不合理的技术问题。
为实现上述目的，本申请提供一种带宽划分方法，所述带宽划分方法应用于网络系统；

确定各类非实时业务数据各自对应的带宽占比，以及确定所述非实时业务数据在所述网络系统中的总带宽；
根据所述总带宽和各个所述带宽占比，确定各类所述非实时业务数据的目标带宽，所述目标带宽用于限制单位时间内各类所述非实时业务数据的数据传输量。
在一实施例中，所述网络系统包括主站设备、从站设备以及监视器；所述带宽划分方法，还包括：
获取各类所述非实时业务数据的服务响应时间，根据各个所述服务响应时间确定各类所述非实时业务数据的响应优先级，所述服务响应时间与所述响应优先级之间成反比；
所述从站设备用于基于所述响应优先级响应所述主站设备或者所述监视器发送的各类所述非实时业务数据。
在一实施例中，所述确定各类非实时业务数据各自对应的带宽占比的步骤，包括：
获取当前的各类非实时业务数据的目标数据量和非实时业务数据总量；

在一实施例中，所述确定各类非实时业务数据各自对应的带宽占比的步骤，包括：
获取各类非实时业务数据的历史平均数据量和非实时业务数据历史平均总量；
根据各个所述历史平均数据量和所述非实时业务数据历史平均总量，确定各类所述非实时业务数据各自对应的带宽占比。
在一实施例中，在所述确定各类所述非实时业务数据的目标带宽的步骤之后，所述方法还包括：
获取当前待传输非实时业务数据的单位待传输数据量；
判断所述单位待传输数据量是否大于所述当前待传输非实时业务数据的目标带宽；
若所述单位待传输数据量大于所述当前待传输非实时业务数据的目标带宽，则输出数据量超限的提示信息。
在一实施例中，所述确定所述非实时业务数据在所述网络系统中的总带宽的步骤，包括：
获取所述网络系统中的监视器和所述网络系统中的主站设备之间的通信周期和非实时数据的周期允许量；
根据所述通信周期和所述周期允许量，计算得到所述非实时业务数据在所述网络系统中的总带宽。
在一实施例中，所述根据所述总带宽和各个所述带宽占比，确定各类所述非实时业务数据的目标带宽的步骤，包括：
将所述总带宽乘以各个所述带宽占比得到的各个乘积，并将各所述乘积作为各类所述非实时业务数据的目标带宽。
此外，为实现上述目的，本申请还提供一种带宽划分装置，所述带宽划分装置，包括：

在现有的工业以太网总线中，如PROFINET、EtherCAT、EtherNetIP协议都会对总线的带宽进行划分，但也仅仅划分为实时的数据和非实时的数据两大类带宽，也就是实时数据占据总线的一部分带宽，非实时数据占据总线的另一部分带宽。
本申请主要是通过对非实时数据占据的总线的总带宽进一步进行划分，具体通过各个不同种类的非实时业务数据对应的带宽占比，也就是不同种类的非实时业务数据在单位时间内所需占用的带宽的比值，以及通过计算得到的所有非实时数据占据的总线的总带宽对各类非实时业务数据分配不同的目标带宽，限制各类非实时业务数据只能在许可的带宽内进行数据传输，进而就不会使得多个不同种类的非实时业务数据同时抢占同一带宽，从而使得非实时业务数据分配更加科学合理，避免了非实时业务数据的丢失以及加快从站设备对主站设备和监视器发送的非实时业务数据响应效率。

应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请技术方案中的实施例简述：
本申请主要是基于非实时数据（非实时业务数据）的种类，以及不同种类的非实时数据的数据量大小以及重要程度层面来对非实时数据分配不同的目标带宽，使得不同种类的非实时数据仅在其对应的目标带宽限制内进行数据的传输以及提醒使用网络系统的用户谨慎选择非实时数据，从而避免所有的非实时数据都在同一时间抢占同一带宽导致数据的丢失等问题。
本申请实施例提出一种带宽划分设备。带宽划分设备可以包括等任意类型的含有网络系统的通信设备，在此不做限制。
如图1所示，图1是本申请实施例方案涉及的带宽划分设备的硬件运行环境的结构示意图。
如图1所示，该带宽划分设备可以包括：处理器1001，例如CPU，网络接口1004，用户接口1003，存储器1005，通信总线1002。其中，通信总线1002用于实现这些组件之间的连接通信。用户接口1003可以包括显示器（Display）、输入单元比如控制面板，用户接口1003还可以包括标准的有线接口、无线接口。网络接口1004可以包括标准的有线接口、无线接口（如WIFI接口）。存储器1005可以是高速RAM存储器，也可以是稳定的存储器（non-volatile memory），例如磁盘存储器。存储器1005还可以是独立于前述处理器1001的存储装置。作为一种计算机存储介质的存储器1005中可以包括带宽划分程序。
本领域技术人员可以理解，图1中示出的硬件结构并不构成对设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
继续参照图1，图1中作为一种计算机可读存储介质的存储器1005可以包括操作系统、用户接口模块、网络通信模块以及带宽划分程序。
在图1中，网络通信模块主要用于连接服务器，与服务器进行数据通信；而处理器1001可以调用存储器1005中存储的带宽划分程序，并执行以下各个实施例中的步骤。
基于上述控制器的硬件结构，提出本申请带宽划分方法的各个实施例。
本申请实施例提供一种带宽划分方法。
请参照图2，图2为本申请带宽划分方法第一实施例的流程示意图；在本申请第一实施例中，所述带宽划分方法应用于网络系统，所述网络系统包括监视器和主站设备，所述监视器和所述主站设备通信连接；此外，网络系统还包括从站设备。
为了便于理解本实施例中的网络系统，请参照图5，图5为本申请带宽划分方法涉及的网络系统的网络拓扑示例图。
如图5所示，在本实施网络系统的网络拓扑中，包含了主站设备和多个从站设备以及一个监视器，拓扑结构不限于总线型，包含环形、星型，监视器的位置也不限于只连接在主站设备上，还可以连接在从站设备的末端，或者通过交换机接入从站设备，或者与主站设备集成一体成显控一体型的主站设备。
其中的监视器是指产生非实时业务数据（也可称为非周期业务数据）的终端，此类非实时业务数据包含参数的读写，生产者消费者模型的监控数据，如监控通道数据。需要说明的是无论是上述哪一种拓扑结构，都要确保监视器、主站、从站之间能够相互通信。
另外，图5中各个标号的意义：
标号1，指网络系统中的从站设备，从站设备是被监控和调试的设备，主要是按照监视器配置的参数进行数据的采集上报和命令的响应。
标号2，指网络系统中的主站设备，主站设备是执行的大脑，控制从站设备的执行，所有的实时数据由主站设备管控，主站设备具备计算非实时数据带宽的关键要素，如通信周期、每一个节点的非实时数据大小、组网总的节点个数，用户分配的实时数据带宽占用比。
标号3，指网络系统中的监视器，监视器是用于调试和监控从站设备的软件或者终端，是发起非实时数据业务的源头，用户通过操作监视器，可以获取到多个从站设备的各类信息。
标号4，指网络系统中监视器可以与从站设备进行通信，即使监视器没有与从站直接链接，监视器也可以与主站通信。
在上述网络系统结构的基础上，所述带宽划分方法包括以下步骤：
步骤S10，确定各类非实时业务数据各自对应的带宽占比，以及确定所述非实时业务数据在所述网络系统中的总带宽；
获取各个种类的非实时业务数据对应的带宽占比，既可以以各种非实时业务数据的数据量占全部非实时业务数据的比例来进行确定，也可以根据不同种非实时业务数据在数据传输中的重要程度进行预设带宽占比，即可以根据技术人员的经验来确定各类非实时业务数据对应的预设带宽占比，这里的重要程度的标准可以为：不允许丢失数据＞可允许丢失小部分数据＞可允许丢失大部分数据＞可允许丢失全部数据。
比如，在一具体示例中：
EtherCAT的SDO服务属于协议定义的标准服务，一般由主站设备业务产生，基于Ethernet Over EtherCAT通道自主定义的连续波形采集服务属于自定义的生产者消费者服务一般由监视器产生，基于Ethernet Over EtherCAT通道自定义的功能码读写属于参数获取服务一般由监视器产生
对于上述的协议定义标准服务数据、生产者消费者服务数据、参数获取服务和其他消耗数据，根据这三种不同非实时业务数据的数据量或者重要程度，对应的带宽占比分别为50%、25%、25%。在此仅做示例理解，并非对各类非实时业务数据对应的带宽占比进行限定。
在一实施例中，步骤S10中的所述确定各类非实时业务数据各自对应的带宽占比的步骤，包括：
步骤a，获取当前的各类非实时业务数据的目标数据量和非实时业务数据总量；
步骤b，根据各个所述目标数据量和所述非实时业务数据总量，确定各类所述非实时业务数据各自对应的带宽占比。
在该实施例中，可以通过获取当前的各类非实时业务数据的目标数据量和非实时业务数据总量，计算当前的各类非实时业务数据的目标数据量相对于当前非实时业务数据总量占比来确定各类非实时业务数据对应的带宽占比，具体来说，就是将当前同一时刻的各类非实时业务数据的目标数据量除以同一时刻的非实时业务数据总量得到各个比值，该比值就是各类所述非实时业务数据各自对应的带宽占比。
通过这一实施例，能够基于各类非实时业务数据的实时的数据量，进而为不同种类的非实时业务数据实时分配不同的目标带宽，能够满足同一时刻各种数据传输的实际需要，防止业务数据的丢失。
在另一实施例中，步骤S10中的所述确定各类非实时业务数据各自对应的带宽占比的步骤，还包括：
步骤c，获取各类非实时业务数据的历史平均数据量和非实时业务数据历史平均总量；
步骤d，根据各个所述历史平均数据量和所述非实时业务数据历史平均总量，确定各类所述非实时业务数据各自对应的带宽占比。
在该实施例中，具体地，获取在预设时长内的各类非实时业务数据的历史平均数据量就是每一种类的非实时业务数据在预设时长内的数据传输总量除以预设时长得到的平均值，获取预设时长内的非实时业务数据历史平均总量，也就是所有非实时业务数据的数据传输总量除以预设时长得到的平均值。其中的预设时长可以根据实际需要进行设置，比如一周、一个月等。
再将各个所述历史平均数据量分别除以所述非实时业务数据历史平均总量得到各个比值，从而就确定了各类所述非实时业务数据各自对应的带宽占比。
通过这一实施例，能够在很大程度上反映了在过往历史中不同种类非实时业务数据的传输需求量，进而也能预示之后不同种类非实时业务数据的传输需求量，以各个历史平均数据量为参照确定不同的带宽占比以在后续各类非实时业务数据按照对应的目标带宽进行数据传输，能够确保各类非实时业务数据的稳定传输，使得各类非实时业务数据都能够得到从站设备较为及时高效的响应。
在一实施例中，步骤S10中的所述确定所述非实时业务数据在所述网络系统中的总带宽的步骤，包括：
步骤S11，获取所述网络系统中的监视器和所述网络系统中的主站设备之间的通信周期和非实时数据的周期允许量；
步骤S12，根据所述通信周期和所述周期允许量，计算得到所述非实时业务数据在所述网络系统中的总带宽。
基于监视器与主站设备的通信交互，获取计算非实时业务数据的总带宽的要素（参数），也可以是直接读取主站设备或者网络系统中的控制设备自身已经计算完成的总带宽NRT_bw，其中，计算总带宽的要素可以是通信周期T_c，单周期非实时数据允许发送大小N_b（非实时数据的周期允许量），将所述通信周期和所述周期允许量相乘之后或者将所述通信周期和所述周期允许量以及修正值相乘之后，计算出单位时间（秒）的总带宽，可以看出非实时数据带宽NRT_bw与通信周期T_c和单周期非实时数据大小N_b成正比。再具体地：总带宽的要素包括了通信周期、每一个节点的非实时数据大小、组网总的节点个数，用户分配的实时数据带宽占用比，计算总带宽的方式还可以为：先获取网络系统总线的总带宽，以及根据用户分配的实时数据带宽占用比得到实时数据带宽，将总带宽减去实时数据带宽就得到了所述总带宽。
通过该实施例，能够通过简单的参数便利地计算得到网络系统中所有非实时业务数据的总带宽。
步骤S20，根据所述总带宽和各个所述带宽占比，确定各类所述非实时业务数据的目标带宽，所述目标带宽用于限制单位时间内各类所述非实时业务数据的数据传输量。
在一实施例中，所述步骤S20，包括：
将所述总带宽乘以各个所述带宽占比得到的各个乘积，并将各所述乘积作为各类所述非实时业务数据的目标带宽。
将非实时业务数据的总带宽乘以一类非实时业务数据的带宽占比就得到了该类非实时业务的目标带宽，进而可以得到各个种类的非实时业务数据的目标带宽，比如，非实时业务数据的总带宽为100Mbps，其中非实时业务数据中的协议定义标准服务的带宽占比为50%，对应的，协议定义标准服务的目标带宽就为50Mbps，也就是说，所有的协议定义标准服务的数据传输都需要限制在50Mbps以内，不能再占用更多的带宽，在为了各类非实时业务数据分配好对应的目标带宽之后，就不会再出现抢占总带宽的情形，避免了因抢占带宽造成的数据丢失等问题。
本申请主要是通过对非实时数据占据的总线的总带宽进一步进行划分，具体通过各个不同种类的非实时业务数据对应的带宽占比，也就是不同种类的非实时业务数据在单位时间内所需占用的带宽的比值，以及通过计算得到的所有非实时数据占据的总线的总带宽对各类非实时业务数据分配不同的目标带宽，限制各类非实时业务数据只能在许可的带宽内进行数据传输，进而就不会使得多个不同种类的非实时业务数据同时抢占同一带宽，从而使得非实时业务数据分配更加科学合理，避免了非实时业务数据的丢失以及加快从站设备对主站设备和监视器发送的非实时业务数据响应效率。
请参照图4，图4为本申请带宽划分方法第二实施例的流程示意图；进一步地，基于本申请带宽划分方法的第一实施例提出本申请带宽划分方法的第二实施例，在本实施例中，所述步骤S20之后，所述方法还包括：
步骤S30，获取当前待传输非实时业务数据的单位待传输数据量；
步骤S40，判断所述单位待传输数据量是否大于所述当前待传输非实时业务数据的目标带宽；
步骤S50，若所述单位待传输数据量大于所述当前待传输非实时业务数据的目标带宽，则输出数据量超限的提示信息。
在本实施例中，当前待传输非实时业务数据可以为用户在监视器或者主机与监视器一体机上选择的对部分即将要传输的非实时业务数据。其单位待传输数据量就是允许的每秒传输数据量，通过该单位待传输数据量就可以确定当前待传输非实时业务数据即将占用的带宽，进而判断该单位待传输数据量与该取当前待传输非实时业务数据的目标带宽的大小，如果在判定单位待传输数据量大于当前待传输非实时业务数据的目标带宽时，需要提醒用户所选的非实时业务数据的数据量超限的提示消息，提示的方式不限于弹窗、语音警报、振动等方式。
在一具体示例中：监视器划分好各类非实时数据的目标带宽之后，从而反向限制用户合理的使用非实时业务，如连续波形采集(生产者消费者服务)作为当前待传输非实时业务数据时，其可用的目标带宽为1/4*NRT_bw，那么同一个网络中所监控的节点数所产生的生产者数据不能超过1/4 *NRT_bw，也就是单位待传输数据量不能超过1/4 *NRT_bw，否则会导致其他业务数据受到影响。监视器可以根据用户选择的业务所产生的数据超过其对应的目标带宽时，给予提示和限制，从而达到不同场景下非实时数据与业务合理的分配使用。
在一实施例中，所述网络系统，还包括从站设备；所述带宽划分方法，还包括：
获取各类所述非实时业务数据的服务响应时间，根据各个所述服务响应时间确定各类所述非实时业务数据的响应优先级，所述服务响应时间与所述响应优先级之间成反比；
所述从站设备用于基于所述响应优先级响应所述主站设备或者所述监视器发送的各类所述非实时业务数据。
在该实施例中，各类非实时业务数据都有其所需的服务响应时间T_Rsp，也就是主站设备或者监视器发送非实时业务数据需要从站设备在服务响应时间内进行响应，否则将会产生影响接下来的数据传输，所以基于服务响应时间的长短对各类非实时业务数据设定优先级，优先级越高的服务响应时间越短，根据不同种非实时业务数据的优先级，从站设备在各类非实时业务数据对应的目标带宽限度内按照优先级进行依次响应。
比如，优先级分配为：最高优先级(协议定义标准服务)、中等优先级（生产者消费者服务）、最低优先级（参数获取服务和其他消耗），优先级被用于从站设备中，当从站设备同时需要回复不同优先级的非实时业务数据时，优先回复高优先级的非实时业务数据。
通过该实施例，确保了对服务响应时间要求高的非实时业务数据能够得到较为快速高效地响应，避免了一些对回复时间有较高要求的非实时业务数据因从站设备回复响应时间长造成各种数据传输障碍影响接下来的数据传输。
为了进一步理解本申请的上述各个实施例，可以参照图6，图6为本申请带宽划分方法的整体应用流程示意图，本申请在实际的应用场景中整体流程可以为：
步骤1，监视器获取计算贷款元素，并计算出非实时数据的总带宽；
步骤2，划分各类实时数据的目标带宽；
步骤3，根据划分好的非实时数据的目标带宽，分配对应业务的规格，当用户选择的业务超过数据带宽时，给予提示。

所述从站设备用于基于所述响应优先级响应所述主站设备或者所述监视器发送的各类所述非实时业务数据。
在一实施例中，数据获取模块A10，还用于：

根据各个所述目标数据量和所述非实时业务数据总量，确定各类所述非实时业务数据各自对应的带宽占比。

判断所述单位待传输数据量是否大于所述当前待传输非实时业务数据的目标带宽；
若所述单位待传输数据量大于所述当前待传输非实时业务数据的目标带宽，则输出数据量超限的提示信息。
