具体实施方式
下面将结合本发明实施例中的附图,对本发明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发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
在不冲突的情况下,下述的实施例及实施方式中的特征可以相互组合。
本发明实施例提供一种消息流显示方法,该消息流显示方法用于消息传输系统,所述消息传输系统可以包括多个节点,每个所述节点与至少一个其他节点通信连接。需要说明的是,本发明实施例中,节点为通信的设备或模块。
如图2所示,所述消息流显示方法包括可以包括如下步骤:
S201:创建每一节点的显示标识以及节点的输入消息和/或输出消息的显示标识,使得节点的输入消息和/或输出消息的显示标识设于节点的显示标识周围;
需要说明的是,一些消息可仅作为输入消息或输出消息,一些消息可既作为输入消息,也可作为输出消息。如图3所示,消息5仅作为输入消息,消息1、消息2、消 息3、消息4以及消息6既作为输入消息,也作为输出消息。
在某些实施例中,显示标识为显示框。可选的,节点的显示框的形状区别于输入消息的显示框的形状以及输出消息的显示框的形状,以更好的区分节点和消息。可选的,输入消息的显示框的现在与输出消息的显示框的形状相同。显示框可以为方形、圆形、椭圆形等规则形状,也可以为非规则形状,作为一种可行的实现方式,节点的显示框为方形,输入消息的显示框以及输出消息的显示框均为椭圆形。可以理解,显示标识也可采用其他方式标识,不限于显示框。
进一步的,在某些实施例中,节点的显示框内设有该节点的身份标识;在某些实施例中,输入消息的显示框内设有该输入消息的身份标识;在某些实施例中,输出消息的显示框内设有该输出消息的身份标识;在某些实施例中,如图3所示,节点的显示框内设有该节点的身份标识(图3中的“节点1”和“节点2”),输入消息的显示框内设有输入消息的身份标识(图3中的“消息1”、“消息2”、“消息3”、“消息4”、“消息5”和“消息6”),并且,输出消息的显示框内设有输出消息的身份标识(图3中的“消息4”和“消息6”);在某些实施例中,输入消息的显示框内设有输入消息的身份标识,并且,输出息的显示框内设有输出消息的身份标识;可以理解,上述实施例可以相互组合。
节点的显示标识周围可以为节点的显示标识的左侧、右侧、上方以及下方中的至少一个,可选的,对于某一节点,将该节点的输入消息的显示标识设于该节点的显示标识的左侧,并将该节点的输出消息的显示标识设于该节点的右侧,但不限于该设置方式。
S202:在节点与节点的输入消息和/或输出消息之间创建连接标识,以指示节点的消息流向。
本实施例中,连接标识为连接线。进一步的,连接线的一端设有箭头,方便用户判断消息的流向。在某些实施例中,节点与输入消息之间的连接线的箭头指向节点;在某些实施例中,节点与输出消息之间的连接线的箭头指向输出消息;在某些实施例中,节点与输入消息之间的连接线的箭头指向节点,并且,节点与输出消息之间的连接线的箭头指向输出消息。
可以理解,连接标识不限于连接线的形式,也可以采用其他连接标识。
需要说明的,基于步骤S201-202创建获得的链路关系图可以通过显示装置显示,该显示装置可以为消息传输系统的一部分,也可以为其他设备的显示装置。
本发明实施例的消息流显示方法,以节点为中心来记录消息传输系统中各节点发布、订阅的消息(发布的消息即为输出消息,订阅的消息即为输入消息),从而形成链路关系图,能够准确地显示同一节点的消息流入和/或流出情况,方便用户进行同一节点消息同步的调试。
在某些实施例中,消息流显示方法还包括:在输入消息的周围和/或输入消息对应的连接标识的周围显示输入消息的关联信息,方便用户对同一节点的输入消息的状态进行判断;在某些实施例中,消息流显示方法还包括:在输出消息的周围和/或输出消息对应的连接标识的周围显示输出消息的关联信息,方便用户对同一节点的输出消息的状态进行判断;在某些实施例中,在输入消息的周围和/或输入消息对应的连接标识的周围显示输入消息的关联信息,并且,在输出消息的周围和/或输出消息对应的连接标识的周围显示输出消息的关联信息,方便用户对同一节点的输入消息的状态以及同一节点的输出消息进行判断。
需要说明的是,输入消息的周围可以包括该输入消息的左侧、右侧、上方和下方中的至少一个,输出消息的周围可以包括该输出消息的左侧、右侧、上方和下方中的至少一个。以连接线为例,连接标识的周围可以包括该连接线的上方和下方中的至少一个。
结合图4A、图4B以及图4C,关联信息可以包括但不限于:对应消息的时间戳和/或传输频率和/或延时时间,该对应消息即为输入消息或输出消息,基于上述关联信息,用户可以定位对应消息输出延时和/或丢帧的原因,如某个消息输出延时的原因可能是上游消息的延时、丢帧、节点处理时间过长等中的至少一个,从而提高同步消息处理时的调试效率;同时,还可以展示消息之间的相对延迟。
又结合图4A、图4B以及图4C,假设消息传输系统在理想的信号传输状态下,每个消息的传输频率均为20HZ;而实际中,由于消息的延时、丢帧、节点处理时间过长等因素,可能导致某一个或多个消息的传输频率小于20HZ,如消息6的传输频率为19.9HZ,小于20HZ,可能为以下三种原因中的一个:
(1)消息4和消息5中至少一个的传输频率小于20HZ;
(2)消息4和消息5的传输频率均为20HZ,节点2对消息4和消息5进行处理,获得消息6,若节点2处理消息4和消息5的时间小于或等于预设时间阈值(如50ms),消息6的传输频率则为20HZ;若节点2处理消息4和消息5的时间大于预设时间阈值(如50ms),消息6的传输频率则小于20HZ;也即,节点2处理处理消息4和消息5的时间过长导致消息6的传输频率小于20HZ;
(3)消息4和消息5的时间戳未对准,如消息4与消息5的时间戳相差200ms,消息4的时间戳为800ms时,消息5的时间戳则为1000ms;消息4的时间戳为950ms时,消息5的时间戳则为750ms,消息4和消息5的时间戳不统一导致消息6的传输频率小于20HZ。
可选的,时间戳包括以下一个或两个的组合:输出对应消息的节点获得对应消息的第一时间信息;输出对应消息的节点输出对应消息的第二时间信息。其中,第一时间信息可以包括基于一种或多种时钟模式确定的时间,可选的,第一时间信息包括: 输出对应消息的节点基于第一时钟模式所确定的其获得对应消息的时间信息;可选的,第一时间信息包括:输出对应消息的节点基于第二时钟模式所确定的其获得对应消息的时间信息;可选的,第一时间信息包括:输出对应消息的节点基于第一时钟模式所确定的其获得对应消息的时间信息,以及输出对应消息的节点基于第二时钟模式所确定的其获得对应消息的时间信息。可选的,第一时钟模式为基于硬件的时钟模式,第二时钟模式为基于软件的时钟模式。第二时间信息为输出对应消息的节点投递对于消息的时间。
另外,本实施例的消息流显示方法可以按照一定的频率更新消息流显示方式,例如,可以按照一定的频率更新关联信息,在连接标识的周围显示对应的消息的关联信息时,可选的,按照预设频率,更新输入消息的周围和/或输入消息对应的连接标识的周围显示输入消息的关联信息;可选的,按照预设频率,更新输出消息的周围和/或输出消息对应的连接标识的周围显示输出消息的关联信息;可选的,按照预设频率,更新输入消息的周围和/或输入消息对应的连接标识的周围显示输入消息的关联信息;并且,按照预设频率,更新输出消息的周围和/或输出消息对应的连接标识的周围显示输出消息的关联信息。预设频率可根据需要设置,如每200ms更新一次。
如图5A所示,节点的显示框中设有操作模块。本实施例的消息流显示方法还可以包括:当操作模块被触发时,展开节点的显示框大小,并在展开后的节点的显示框中显示输入节点的各输入消息的时间戳相对同一时间轴的位置。其中,时间戳用于指示节点获得或输出对应输入消息的时间信息。
操作模块可以包括一个或多个,本实施例中,操作模块的数量根据关联信息中每个消息的时间戳的数量决定。在某些实施例中,操作模块包括多个,多个操作模块与节点的各输入消息的不同类型的时间戳对应。在展开后的节点的显示框中显示输入节点的各输入消息的时间戳相对同一时间轴的位置时,具体的,在展开后的节点的显示框中显示输入节点的各输入消息的对应类型的时间戳相对同一时间轴的位置。
例如,在图5A所示实施例中,每个消息包括基于第一时钟模式确定的第一时间信息、基于第二时钟模式确定的第一时间信息以及第二时间信息三个时间戳,节点1的操作模块包括3个,分别为操作模块1、操作模块2以及操作模块3。当操作模块1被触发时,并在展开后的节点的显示框中显示输入节点的各输入消息基于第一时钟模式确定的第一时间信息相对相同时间轴的位置;当操作模块2被触发时,并在展开后的节点的显示框中显示输入节点的各输入消息基于第二时钟模式确定的第一时间信息相对相同时间轴的位置;当操作模块3被触发时,并在展开后的节点的显示框中显示输入节点的各输入消息的第二时间信息相对相同时间轴的位置。结合图5A和图5B,当节点1的操作模块1被触发时,展开节点1的显示框大小,并在展开后的节点1的显示框中显示输入节点1的消息1、消息2以及消息3基于第一时钟模式确定的第一时间信息相对同一时间轴t的位置。
时间轴可以为一横坐标轴,也可以为一纵坐标轴,也可以为其他方向的坐标轴,具体根据输入节点的各输入消息与该节点的连接位置确定。
在图5B所示实施例中,时间轴为一横坐标轴,节点的各输入消息的时间戳相对同一时间轴的位置显示在不同的高度上,在不同的高度上标示不同输入消息的时间戳的位置,便于用户识别各输入消息的时间戳的位置。
进一步的,为使得用户能够较快识别各输入消息的时间戳的位置,以获得同一节点各输入消息之间的延时情况,在某些实施例中,所述消息流显示方法还包括:采用横向的第一标识线(如图5B中位于显示框内的连接线)连接对应消息的连接标识与对应消息的时间戳相对同一时间轴的位置;在某些实施例中,所述消息流显示方法还包括:显示穿设对应消息的时间戳相对同一时间轴的位置的第二标识线(如图5B中的虚线),并且第二标识线垂直于时间轴;在某些实施例中,所述消息流显示方法还包括:采用横向的第一标识线连接对应消息的连接标识与对应消息的时间戳相对同一时间轴的位置,并且,显示穿设对应消息的时间戳相对同一时间轴的位置的第二标识线。
此外,在某些实施例中,消息流显示方法还可以包括:当操作模块被触发时,在节点的显示框的顶部或底部显示时间轴,时间轴与节点的显示框相平行,更加具体地显示各节点的各输入消息之间的延时情况。如5B所示,在节点1的显示框的底部显示时间轴t,该时间轴t与节点1的显示框的长度方向平行。
展开节点的显示框大小的方式可根据显示框的形状确定,以节点的显示框为方形框为例,可选的,增大节点的显示框的横向边长,从而实现节点的显示框大小的展开;可选的,增大节点的显示框的纵向边长,从而实现节点的显示框大小的展开;可选的,同时增大节点的显示框的横向边长和纵向边长,从而实现节点的显示框大小的展开。
