具体实施方式
为了使本技术领域的人员更好地理解本申请方案，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，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域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，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或模块或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或模块或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或模块或单元。
根据本申请实施例，提供了仿真生产过程的方法。图1是根据本申请实施例的仿真生产过程的方法的流程图。如图1所示，根据本申请实施例的仿真生产过程的方法 100包括：步骤S101，从可编程逻辑控制器接收一个或多个设备的运行数据。仿真生产过程所需的数据是从可编程逻辑控制器(PLC)中获取的，可编程逻辑控制器中包括生产中的设备的运行数据，运行数据指示设备运行时的相关属性、参数和变量等，代表设备执行的动作。这些数据从可编程逻辑控制器接收，以供后续的处理。步骤S103，从运行数据中筛选出能用于仿真处理的部分运行数据。在从可编程逻辑控制器接收到运行数据后，由于不是全部的运行数据能在仿真处理中起到作用，因此，需要筛选出所需要的运行数据。筛选的部分运行数据包括指示一个或多个设备在生产过程中执行的动作的信息。例如，筛选出能够指示设备在何时进行了什么动作以及何时结束该动作的运行数据，这些数据将在以后的仿真过程中用于指示仿真设备执行相应的仿真动作。步骤S105，根据部分运行数据生成仿真数据，仿真数据指示与一个或多个设备对应的一个或多个仿真设备执行与动作对应的仿真动作的信息。原有的运行数据指示的是实际的设备在生产过程中的动作信息，在分析了这些运行数据后，根据设备在生产过程中的动作信息，对应地生成仿真处理中仿真设备进行的仿真动作的信号，以在仿真处理中指示对应的仿真设备执行与生产过程中的动作对应的仿真动作。步骤S107，将仿真数据传输到云平台。在获得能够用于仿真处理的仿真数据后，仿真数据被上传到云平台。上传可以通过云平台的通信接口(例如MindSphere云平台的MLC)，传输到云平台后可以存储在云平台的数据库中。以这样的方式，关注的生产过程的设备的运行数据被转换为仿真数据并上传到云平台，使仿真数据能够用于远程的仿真平台，方便进行仿真处理。
根据本申请的示例性实施例，在步骤S105，根据部分运行数据生成仿真数据具体包括：确定动作、一个或多个设备执行动作的时间以及设备执行动作的部件。接收到用于仿真处理的部分运行数据后，对运行数据进行分析，分析的过程在翻译器的动作分析模块中进行，其分析运行数据，得到运行数据指示的设备在生产过程中执行的动作，以及执行该动作的时间(例如动作的开始时间、结束时间)。此外，动作是细化的动作，不能被进一步分解，是由设备的具体部件做出的动作，以这样的方式，对具体的动作进行仿真，反映生产过程中的具体细节。确定设备执行该动作的部件，以用于仿真设备一致地执行仿真动作，将设备具体动作相关的数据用于仿真处理，完整仿真生产过程。
根据本申请的示例性实施例，在步骤S107，将仿真数据传输到云平台包括：根据动作的时间顺序以预定周期传输仿真数据。设备的运行数据的获取是按照时间顺序从可编程逻辑控制器获取的，也按照时间顺序对运行数据进行分析以生成仿真数据，为了正确指示实际生产中设备执行的动作的时间顺序，以及确定传输的仿真数据被成功接收。每隔一个预定的周期进行一次仿真数据向云平台的传输。以这样的方式，保证 仿真数据的完整性和正确性。用于完整仿真的仿真数据具有很高的要求，例如，仿真数据需要完整并且准确对应设备的动作，以在仿真平台进行准确回放。仿真数据具备准确的动作时间，时间的提前或延迟可能对回放仿真过程造成影响，并且仿真数据不能丢失或重复，这可能造成仿真过程中出现错误。仿真数据包括了每个动作的开始和结束时间，以支持后续在仿真过程中仅对特定时间段进行的仿真。仿真数据所指示的仿真设备进行的仿真动作相关的时间也与设备实际进行的动作相关的时间保持更新和同步，以保证仿真过程准确反映动作的时间点，从而帮助进行故障排查或流程优化等操作。仿真数据准确反映动作的时间也帮助用户在回放时，准确找到关注的生产过程，容易进行对生产过程中关键点的观察和分析。
在设备开始进行实际的生产时，可编程逻辑控制器会监控设备的运行，并获得设备运行时产生的信号，这些信号指示了设备的运行状态，其中，根据实际需求，指示设备执行的动作以及动作相关时间的信号用作仿真采用的数据，例如包括设备名、信号名、数据的值以及描述等信息，据此生成仿真数据，并将仿真数据传输到云平台并存储在数据库中。
在将仿真数据传输到云平台的过程中，可以调用数据上传服务，周期性地上传仿真数据，周期例如是1秒或2秒，也可以是更短的周期，具体周期的选择基于用户需求可以调整，以满足不同的数据粒度，或者节省硬件需求。为了确认数据被完整且正确地上传到云平台，云平台发送确认正确接收仿真数据的反馈。
根据本申请的示例性实施例，从可编程逻辑控制器根据用户设置的频率接收一个或多个设备的运行数据。可编程逻辑控制器以时间顺序获取运行数据，每隔一个周期获取一次运行数据，用户能够根据需要或工厂实际情况设置需要的获取频率。以这样的方式，按照仿真的实际需要获取生产设备的运行数据。
根据本申请的示例性实施例，根据用户设定的筛选条件从运行数据中筛选出能用于仿真处理的部分运行数据。用户可以选择需要的运行数据，例如，对于特定的设备，选择特定时间范围内的运行数据，也可以选择指示设备的动作相关信息的运行数据，或者选择设备特定部分执行的动作对应的运行数据，只要这些数据满足用户所需的仿真处理过程，均可被用户设为筛选条件，以供选择需要的数据。以这样的方式，按照仿真的实际需要准备用于仿真处理的关注的运行数据。
根据本申请实施例的另一个实施例，还提供了仿真生产过程的方法。图2是根据本申请示例性实施例的仿真生产过程的方法的流程图。如图2所示，根据本申请示例性实施例的仿真生产过程的方法200包括：步骤S201，接收回放条件。回放条件是用户根据需要的仿真处理设置的，例如，用户可以根据需要选择实时回放、对关注的一 段时间进行快速回放或慢速播放，或者对关注的两个时间之间的动作进行回放，用户输入与需要对应的回放条件，则可以根据该输入的回放条件，进行不同的接收动作，以执行满足用户需要的仿真以进行回放。步骤S203，从云平台接收符合回放条件的仿真数据，其中，仿真数据指示与一个或多个设备对应的一个或多个仿真设备执行与一个或多个设备在生产过程中执行的动作对应的仿真动作的信息。仿真数据是根据上文根据本申请实施例的仿真生产过程的方法100向云平台传输的。在方法200，这些数据根据用户需要从云平台的数据库获取。由于采用了云平台存储数据，仿真数据的获取可以是相对于云平台远程进行的，可以采用客户端下载仿真数据，或者采用其他与云平台连接的设备接收仿真数据，然后在步骤S205，根据回放条件将接收的仿真数据按照预定时间间隔传输到仿真平台，对于每种回放条件，向仿真平台传输仿真数据的方式不同，以满足不同的用户需求。以这样的方式，云平台中的仿真数据可以按照需要的回放条件传输到仿真平台，以进行对应的回放。
根据本申请的示例性实施例，该方法还包括按照仿真数据对应的动作的时间顺序从云平台接收符合回放条件的仿真数据。在从云平台接收仿真数据时，接收的仿真数据的时间顺序应当与仿真数据在上传时一致，以保证仿真动作按照正确的顺序进行。为此，对仿真数据中的时间信息进行检测，以保证时间顺序无误。以这样的方式，保证仿真处理能够按照正确时间顺序反映生产过程。
根据本申请的示例性实施例，如果回放条件是实时回放，则接收当前时间前预定时间间隔时的时间至当前时间的仿真数据，并且根据当前时间前预定时间间隔的时间与当前时间分别为仿真数据设置仿真处理的开始和结束的时间戳。对于实时回放，由于仿真处理在仿真平台通过仿真设备完成，而不是由实际的设备完成，因此，仿真动作的时间仅是一种概念，称为仿真时间。为了进行实时回放，将仿真时间与实际时间进行同步。仿真数据是按照时间间隔被传递到仿真平台以用于仿真的，确定该时间间隔使仿真动作的仿真时间与实际时间一致，则在仿真平台可以进行同步的仿真。图3是根据本申请示例性实施例的进行实时回放的过程的流程图。如图3所示，根据本申请示例性实施例的进行实时回放的过程300包括：步骤S301，设置当前时间为T，当前时间前预定时间间隔时的时间为T-interval。接着进行步骤S303，对于仿真动作，接收动作开始的仿真时间为T-interval并且结束时的仿真时间为T的仿真数据，预定时间间隔可以是1秒、2秒或更短的时间间隔，可以由用户根据需要的粒度设置。接下来进行步骤S305，为接收的仿真数据设置时间戳，时间戳是根据当前时间T和当前时间前预定时间间隔时的时间T-interval设置的，使得在仿真处理中，仿真的动作将根据当前时间T和当前时间前预定时间间隔时的时间T-interval作为开始时间和结束时间进行。步骤S307，将仿真数据传输到仿真平台或仿真软件，仿真平台或仿真软件 将根据当前时间T和当前时间前预定时间间隔时的时间T-interval使仿真设备执行仿真动作。不断重复这样的过程，其中接收仿真数据的时间间隔与传输仿真数据到仿真平台或仿真软件的时间间隔相同，且回放的延迟仅受到传输过程中的网络延时和预定时间间隔的影响，因此回放可以以用户设置的时间间隔的粒度实时或者近实时的进行。
根据本申请的示例性实施例，除了进行实时回放外，可以对特定时间段进行快速回放或者慢速回放。在实时回放的过程中，仿真数据按照时间间隔传输到仿真平台或仿真软件，使得从云平台获取仿真数据的时间与向仿真平台或仿真软件传输仿真数据的时间间隔相同。如果回放条件是预定时间段之间的快速回放，则接收预定时间段之间的仿真数据，相对于实时回放，缩短预定时间间隔使其比符合实时回放的时间间隔短，则仿真数据以相对于实际时间更快的频率传输到仿真软件或仿真平台，例如，对于实际时间间隔为2秒的动作，以1秒的时间间隔发送该动作，则仿真处理的回放速度加速。以这样的方式，可以快速回放预定时间段的仿真处理。根据本申请的示例性实施例，如果回放条件是预定时间段之间的慢速回放，则接收预定时间段之间的仿真数据，与快速回放相反，延长预定时间间隔使其比符合实时回放的时间间隔长，则仿真数据以相对于实际时间更慢的频率传输到仿真软件或仿真平台，例如，对于实际时间间隔为2秒的动作，以4秒的时间间隔发送该动作，则仿真处理的回放速度被减慢。以这样的方式，可以慢速回放预定时间段的仿真处理。如此，根据加速和减速的回放速度需要调整向仿真平台或仿真软件发送仿真数据的时间间隔，可以实现快速回放或者慢速回放。
根据本申请的示例性实施例，如果回放条件是回放设备的动作，则根据仿真数据指示的动作的改变确定动作的开始时间与结束时间，根据开始时间与结束时间设置仿真处理的开始和结束的时间戳。仿真数据包括的动作具有开始时间和结束时间，并且仿真数据包括动作的名称、涉及的设备、设备执行动作的部件等信息，这些信息被用来区分生产的不同过程，具体地，过程对应不同的动作。由于不同动作的信息是不同的，当仿真数据中指示的动作相关的信息发生改变时，可知开始发生另一个动作。当改变达到用户根据不同动作而设置的阈值时，则当前动作结束，由此可以确定动作的开始时间和结束时间。将开始时间和结束时间设为该动作的开始和结束的时间戳，在仿真平台或仿真软件进行仿真时则可以在该动作的开始时间和结束时间执行对应的仿真，以这样的方式，可以方便回放用户关注的生产过程的仿真处理。
根据本申请的示例性实施例，在接收仿真数据时，检测接收的仿真数据的准确性。以这样的方式，保证仿真处理完整反映关注的生产过程。
根据本申请实施例的另一实施例，还提供了仿真生产过程的装置。图4是根据本 申请另一实施例的仿真生产过程的装置的框图。如图4所示，根据本申请另一实施例的仿真生产过程的装置4包括：数据收集单元41，从可编程逻辑控制器接收一个或多个设备的运行数据；数据筛选单元43，从运行数据中筛选出能用于仿真处理的部分运行数据，其中，所筛选的部分运行数据包括指示一个或多个设备在生产过程中执行的动作的信息；仿真数据生成单元45，根据部分运行数据生成仿真数据，仿真数据指示与一个或多个设备对应的一个或多个仿真设备执行与动作对应的仿真动作的信息；以及数据上传单元47，将仿真数据传输到云平台。图4所示的装置4执行根据本申请实施例的仿真生产过程的方法100，在此不再赘述。以这样的方式，关注的生产过程的设备的运行数据被转换为仿真数据并上传到云平台，使仿真数据能够用于远程的仿真平台，方便进行仿真处理。
根据本申请的示例性实施例，还提供了另一仿真生产过程的装置。图5是根据本申请示例性实施例的仿真生产过程的装置的框图。如图5所示，根据本申请示例性实施例的仿真生产过程的装置5在根据本申请另一实施例的仿真生产过程的装置4的基础上，还包括：输入单元51，接收回放条件；接收单元53，从云平台接收符合回放条件的仿真数据；发送单元55，根据回放条件将接收的仿真数据按照预定时间间隔传输到仿真平台。图5所示的装置5执行根据本申请另一实施例的仿真生产过程的方法200，在此不再赘述。以这样的方式，云平台中的仿真数据可以按照需要的回放条件传输到仿真平台，以进行对应的回放。此外，根据本申请示例性实施例，输入单元、接收单元和发送单元可以设置在另外的装置中，例如，可以设置在远程设备、移动设备等客户端设备中，以通过网络从云平台接收仿真数据，并发送仿真数据到仿真平台，该设备可以远离根据本申请另一实施例的仿真生产过程的装置4或云平台设置。
根据本申请实施例的另一实施例，还提供了仿真生产过程的系统。图6是根据本申请实施例的另一实施例的仿真生产过程的系统的框图。如图6所示，根据本申请实施例的另一实施例的仿真生产过程的系统6包括：数据记录装置40；回放客户端50；云平台70；可编程逻辑控制器80；以及仿真平台90，其中数据记录装置40包括：数据收集单元401，从可编程逻辑控制器80接收一个或多个设备的运行数据；数据筛选单元403，从运行数据中筛选出能用于仿真处理的部分运行数据，其中，所筛选的部分运行数据包括指示一个或多个设备在生产过程中执行的动作的信息；仿真数据生成单元405，根据部分运行数据生成仿真数据，仿真数据指示与一个或多个设备对应的一个或多个仿真设备执行与动作对应的仿真动作的信息；以及数据上传单元407，将仿真数据传输到云平台70，回放客户端50包括：输入单元501，接收回放条件；接收单元503，从云平台70接收符合回放条件的仿真数据；发送单元505，根据回放条件将接收的仿真数据按照预定时间间隔传输到仿真平台90。系统6中的数据记录装置40 和回放客户端50分别与根据本申请另一实施例的仿真生产过程的装置4和根据本申请实施例的又一实施例的仿真生产过程的装置5对应，在此不再赘述。以这样的方式，关注的生产过程的设备的运行数据被转换为仿真数据并上传到云平台，使仿真数据能够用于远程的仿真平台，方便进行仿真处理，可以按照需要的回放条件传输仿真数据到仿真平台，以进行对应的回放。本申请的数据路由可以使用不同协议，例如HTTPS和OPCUA。该系统由两个主要部分组成，即数据记录和回放。记录是选择适合在仿真平台或仿真软件中实现仿真的信号数据。回放是根据用户需要将仿真数据分组并发送给仿真平台或仿真软件。
