背景技术
在电子地图的应用中，要素点聚合显示是电子地图的一项功能，要素点聚合是用少量的点或图标来表示地图中的所有点，让地图显示更清晰明朗，避免电子地图使用场景中需要呈现的要素点过多时，地图界面显示繁琐，及地图显示占用大量系统资源，引发浏览器的崩溃、卡顿，影响用户体验的问题。地图汇聚技术中，进行要素点聚合是根据多个要素点在地图上的坐标信息以及地图的缩放级别，来通过一定的算法计算地图上的多个网格区块内的要素点个数，把每个网格区块内的所有要素点用一个汇聚点图标来表示，汇聚点图标上一般会带有一个数字来表示本汇聚点代表了多少个要素点。这种要素点聚合的方式，汇聚点只在一定程度上大致表示了其代表的子节点的比较粗略的位置信息，该子节点即为汇聚点对应的要素点，但是没有完整的表达出其子节点的其他状态信息，且当子节点的状态信息发生变化时，也无法体现出子节点的状态变化。

具体实施方式
下面通过具体实施方式结合附图对本实施例作详细说明。
实施例一
本实施例提供一种地图中汇聚点生成方法，请参见图1，该方法可以包括以下步骤。
在步骤110中，确定地图在当前显示比例下需要用一个汇聚点来表示的多个要素点和汇聚点在地图中的显示位置，以及获取要素点的当前状态信息。
在步骤120中，根据要素点的当前状态信息确定汇聚点的显示参数，根据显示参数在显示位置上生成并显示汇聚点。
可选地，在地图的生成过程中，可以根据当前地图的显示比例进行要素点汇聚，形成汇聚点，根据汇聚点对应的要素点的当前状态信息，确定汇聚点的显示参数，根据该显示参数设置汇聚点，并在该汇聚点在地图上的对应位置显示该汇聚点，使得汇聚点可以体现出与汇聚点对应的要素点的状态信息。
对于步骤110，确定汇聚点的方式可以是根据地图的当前显示比例，对当前地图上的多个要素点进行定位，根据网格法等处理方式，对当前要素点进行要素点聚合，形成汇聚点；该汇聚点包括至少一个要素点。
确定汇聚点在地图上的显示位置可以是确定汇聚点对应的要素点，并根据该地图当前的显示比例，确定该汇聚点在当前地图上的显示位置。
获取要素点的当前状态信息可以是通过服务器后台对要素点的状态进行检测，获取多个要素点的当前状态信息。
本实施例中，要素点的状态信息包括：告警信息和告警级别信息中的至少一种。可选地，获取要素点的当前状态信息可以是获取要素点当前对应的告警信息，也可以是获取要素点对应告警的告警级别信息，或者同时获取告警信息和告警级别信息。该告警信息和告警级别信息可以是针对告警事件进行设置的信息，其中告警信息可以包括告警状态，如告警和正常两种状态，还可以包括告警事件信息；告警级别信息可以是零级、一级和二级等，告警级别可以根据告警事件和用户需要设置，其中零级也可以表示无告警，即正常状态。
对于步骤120，根据要素点的当前状态信息确定汇聚点的显示参数，根据显示参数在显示位置上生成并显示汇聚点，即为根据要素点的当前状态信息确定与要素点对应的汇聚点的显示状态。
其中，根据要素点的当前状态信息确定汇聚点的显示参数包括：根据要素点的当前状态信息，查询预设的状态信息与显示参数的对应关系，确定出汇聚点的显示参数。可选地，可以在地图显示管理系统中预先设置汇聚点对应的要素点的状态信息与汇聚点的显示参数的对应关系，如可以设置包含汇聚点对应的要素点的状态信息与汇聚点的显示参数的对应关系的关系表，并将关系表进行存储。在确定了要素点的当前状态信息后，根据该当前状态信息查询预设的 要素点的状态信息与汇聚点的显示参数的对应关系，以确定该要素点对应的汇聚点的显示参数。在确定汇聚点的显示参数后，根据显示参数在汇聚点的显示位置上生成并显示汇聚点。
本实施例中，显示参数可以包括：颜色、大小和形状中的至少一种。可选地，汇聚点对应的要素点的状态信息与汇聚点的显示参数的对应关系可以是汇聚点对应的要素点的状态信息与汇聚点的显示颜色、显示大小和显示形状中至少一种参数的对应关系。例如，当要素点的状态信息包括告警信息时，要素点的状态信息与汇聚点的显示参数的对应关系可以是：与汇聚点对应的所有要素点的状态都为正常，则该汇聚点的显示形状为正方形或者颜色为蓝色；与汇聚点对应的至少一个要素点的状态信息为告警，则该汇聚点的显示形状为圆形或者显示颜色为红色。另外，也可以将多个汇聚点的显示形状和显示颜色设置为相同的，根据显示大小区别汇聚点是否包含有告警状态的要素点。
可选地，当要素点的状态信息包括告警级别信息时，要素点的状态信息与汇聚点的显示参数的对应关系可以是：与汇聚点对应的要素点的告警级别均为零级，则该汇聚点的显示形状为正方形或显示颜色为蓝色；与汇聚点对应的要素点的告警级别包括一级或二级，则该汇聚点的显示形状为圆形或显示颜色为红色；与汇聚点对应的要素点的告警级别包括三级或三级以上，则该汇聚点的显示形状圆形，显示颜色为紫色。即可以根据汇聚点对应的要素点的告警级别选择汇聚点的设置参数，通常根据告警级别高的要素点与汇聚点的对应关系确定该汇聚点的显示参数。另外，汇聚点对应的要素点的状态信息与汇聚点的显示参数的对应关系还可以包括像素点的状态信息与汇聚点的显示大小的对应关系。即可以根据告警信息和告警级别信息等要素点的状态信息，选择汇聚点的颜色、大小和形状中的至少一种参数设置要素点的状态信息与汇聚点的显示参数的对应关系。本实施例中，对要素点的状态信息与汇聚点的显示参数的对应关系的形式不做限定，其可以根据需要设置。另外，根据该显示参数在该汇聚点对应的显示位置上生成并显示汇聚点，可以是根据该显示参数设置汇聚点的显示颜色、显示大小和显示形状中的至少一种参数。
可选地，本实施例中的提供的地图中汇聚点生成方法，还包括：若汇聚点所表示的多个要素点中任一要素点的状态信息发生变化，则重新根据要素点的当前状态信息确定汇聚点的显示参数。
可选地，由于要素点的状态信息会随着告警事件而发生变化，当该要素点 的状态信息发生变化后，为使地图上显示的汇聚点仍能体现出与该汇聚点对应的要素点的当前状态，可以确定要素点的当前状态信息，根据要素点的当前状态信息确定与要素点对应的汇聚点的显示参数，可以根据该显示参数调整汇聚点的显示状态，或生成新的汇聚点替代原显示的汇聚点。
本实施例提供的地图中汇聚点生成方法，在要素点的状态发生变化时，可以根据要素点的状态信息对该要素点对应的汇聚点进行更新，即更新该汇聚点的渲染状态，使得该汇聚点能体现出其对应的要素点的当前状态信息，使得地图的显示更加符合实际情况，为用户提供要素点的状态信息。
可选地，本实施例中的提供的地图中汇聚点生成方法，还包括：若地图的显示比例发生变化，则重新确定地图在当前显示比例下需要用一个汇聚点来表示的多个要素点和新的汇聚点在地图中的新的显示位置，以及获取新的汇聚点所表示的要素点的当前状态信息；根据新的汇聚点所表示的要素点的当前状态信息确定新的汇聚点的显示参数，根据新的汇聚点的显示参数在新的显示位置上生成并显示新的汇聚点。
可选地，当显示地图的显示比例发生变化时，会触发要素点的重新聚合，根据变化后的显示比例生成新的汇聚点，确定该新的汇聚点对应的要素点，及该新的汇聚点在当前地图上的显示位置。确定该新的汇聚点对应的要素点的当前状态信息，根据该当前状态信息确定该新的汇聚点的显示参数，根据该显示参数生成该新的汇聚点在地图上的显示位置，并显示该新的汇聚点。
本实施例提供的地图中汇聚点生成方法，在地图的显示比例发生变化，即地图的缩放层级发生变化时，可以重新进行要素点聚合以生成新的汇聚点，并通过该重新聚合的汇聚点及时体现出与该汇聚点对应的要素点的当前状态信息，使得用户能直观的获取到该汇聚点对应的要素点的状态信息。
本实施例提供的地图中汇聚点生成方法，通过确定地图在当前显示比例下需要用一个汇聚点来表示的多个要素点和汇聚点在地图中的显示位置，以及获取要素点的当前状态信息；根据要素点的当前状态信息确定汇聚点的显示参数，根据显示参数在显示位置上生成并显示汇聚点；即可以根据汇聚点对应的要素点的状态信息设置该汇聚点的显示参数，根据该显示参数生成汇聚点进行显示，使得该汇聚点可以体现出其对应的要素点的状态信息，相比于相关技术中汇聚点只能显示其对应的要素点的个数的方式，可以使得电子地图显示的信息更加多样化，更加符合用户的需求，提高了用户体验。
实施例二
本实施例提供一种地图中汇聚点生成方法，所述方法可以应用于包含浏览器、前台和后台服务器的地图显示管理系统中，通过该地图中汇聚点生成方法进行要素点聚合，形成包含汇聚点的地图并显示的过程可以包括以下步骤。
地图显示管理系统通过浏览器接收用户对地图的打开操作，根据用户对地图的打开操作，进行要素点聚合，形成包含汇聚点的地图并显示。
例如，在初次渲染汇聚点时，地图显示管理系统根据用户打开地图页面的操作，通过后台接口查询出所有要素点相关信息，如要素点的位置信息、显示名称以及状态信息，根据汇聚算法将要素点划分到不同的区块内，将多个区块内的要素点用汇聚点来表示，如图2a所示，形成汇聚点A3、汇聚点B4和汇聚点C。在渲染汇聚点时，对于一个区块来说，需要根据本区块内的要素点中是否有一个或多个要素点有告警信息和告警级别中的至少一种来选择对应的汇聚点的显示参数，并根据该汇聚点的显示参数渲染该区域内的汇聚点。如可以设置对应的要素点的状态都为正常，即无告警的汇聚点的形状为正方形，设置对应的要素点的状态为告警的汇聚点的形状为圆形，以使用户直观地了解到汇聚点对应的要素点的状态信息。
如图2a所示的地图，其中汇聚点A3表示该汇聚点A3对应有三个要素点，汇聚点A3的形状为正方形，则说明该汇聚点对应的三个要素点的状态都为正常；另外，汇聚点B4表示该汇聚点B4对应有四个要素点，其形状为圆形，则说明该汇聚点对应的四个要素点中至少有一个要素点的状态为告警。
可选地，在聚合形成汇聚点时，地图显示管理系统将每个汇聚点是由哪些要素点汇聚而成的信息临时存放在前台缓存中，再根据这些要素点中是否有告警以及告警级别来通知浏览器选择汇聚点的显示参数，进行汇聚点渲染。
可选地，在形成包含汇聚点的地图，并将地图进行显示后，地图显示管理系统检测是否需要对当前显示的地图进行调整，若接收到要素点的状态信息发生变化的消息，则认为需要进行汇聚点调整。在要素点的状态信息发生变化时，进行汇聚点调整的过程可参见图3，其中，获取要素点的状态信息可以是地图显示管理系统中的前台向服务器后台订阅要素点状态信息更新消息，由服务器后台向前台推送要素点状态信息更新消息。
当前台接收到后台服务器推送的要素点状态信息更新消息后，根据该要素 点状态信息更新消息进行待更新汇聚点计算，判断是哪些要素点的状态信息发生变化，确定状态信息发生变化的要素点。当前台根据后台服务器推送的要素点状态信息更新消息，判断要素点的状态信息发生变化后，进行该要素点对应的汇聚点的调整。可选地，可以是由前台根据要素点状态信息确定该要素点的位置信息，然后将待更新汇聚点通知给浏览器，如将该要素点的位置信息和状态信息通知给浏览器，由浏览器根据该位置信息和状态信息对该要素点对应的汇聚点进行重新渲染，调整汇聚点的显示状态。
可选地，前台还可以根据在前台缓存的要素点的汇聚状态来判断状态信息发生变化的要素点是单独存在还是被汇聚到了一个大的汇聚点中。在浏览器接收到前台发送的要素点的位置信息和状态信息后，若该要素点没有被汇聚到一个大的汇聚点中时，则直接重新渲染这个单独存在的要素点，如图2a所示的汇聚点C，若该汇聚点原先的状态信息为正常，则显示为正方形，当该汇聚点状态信息改变为告警时，则将该汇聚点的显示形状调整为圆形，调整后该汇聚点C的显示状态体可参见图2b。如果该要素点被汇聚到一个大的汇聚点中时，则重新渲染该要素点对应的汇聚点，如图2a所示的汇聚点A3，该汇聚点A3对应的三个要素点的状态都为正常，当该汇聚点A3对应的至少一个要素点的状态信息发生变化，变为告警时，将该汇聚点A3的显示形状调整为圆形，调整后的汇聚点A3可如图2b所示。
渲染汇聚点时可以根据告警消息的类型选择不同方式来渲染汇聚点，以突显要素点的告警状态。可选地，如果是告警恢复通知，则需要通过浏览器把汇聚点重新渲染到正常状态；如果是告警发送通知，则需要通过浏览器把汇聚点渲染成告警状态；如果汇聚点原来就对应有告警状态的要素点，但是与该汇聚点对应的要素点的告警级别发生了变化，则也需要通过浏览器把汇聚点渲染为对应的要素点中告警级别最高的要素点对应的显示参数，以表示与该汇聚点对应的要素点的告警级别发生变化。另外，当告警级别发生变化时，可以选择不同的渲染方式来表示不同的告警级别以作区分。
另外，在形成包含汇聚点的地图，并将地图进行显示后，地图显示管理系统检测是否需要对当前显示的地图进行调整，若检测到地图显示比例的调整指令，则认为需要进行当前显示地图的更新。可选地，若是地图的显示比例发生变化，则在地图的显示比例发生变化时，会触发要素点的重新聚合，地图中的原有汇聚点发生改变，并触发对所有的要素点的状态信息和位置信息的判断， 获取所有要素点的当前状态信息，根据地图层级改变后的汇聚状态，判断每个要素点是单独存在还是被汇聚到一个大汇聚点中，根据该要素点的状态信息来渲染单个要素点或者要素点聚合成的汇聚点的图标。
请参见图4，当地图显示比例发生变化时，汇聚点的调整过程可以包括以下步骤。
浏览器上地图的显示比例发生变化，浏览器向前台发送地图显示比例发生改变的消息，通知前台地图的显示比例发生了变化；前台接收到地图显示比例发生改变的消息后，根据地图当前缩放层级或显示比例重新汇聚地图中的要素点，并对当前地图中的要素点的状态信息进行待更新汇聚点计算，确定需要重新渲染的汇聚点，通知浏览器需要重新渲染的汇聚点，使得浏览器进行汇聚点的重新渲染，浏览器将更新后的地图显示在地图显示界面上，以使得显示出的地图能实时体现出与多个汇聚点对应的要素点的状态信息。
可选地，将图2a或图2b所示的地图进行放大后，可如图2c所示，其中，由于地图的显示比例变大，使得原汇聚点B4重新汇聚后成为汇聚点b和汇聚点b3，由于原汇聚点B4中的要素点b的状态为告警，则独立显示的只包含要素点b的汇聚点b的显示形状为圆形；而汇聚点b3对应的三个要素点的状态都为正常，该汇聚点b3的显示形状为正方形。另外，若是将图2a或图2b所示的地图进行缩小，则有可能使得汇聚点A3和汇聚点B4形成一个新的汇聚点，此时由于汇聚点B4对应有状态为告警的要素点，则新生成的汇聚点的显示形状为圆形。
本实施例中，在汇聚点对应的要素点的状态信息发生变化或者地图的显示比例发生变化时，对地图上的汇聚点的显示参数进行重新调整，即对汇聚点重新进行渲染，使得汇聚点能根据与该汇聚点对应的要素点的状态信息的变化或者地图的显示比例的变化，调整汇聚点的显示形式，使得电子地图能够实时、便捷的反映出与汇聚点对应的要素点的状态，给用户更好的地图使用体验，且不会使用户遗漏主要的要素点的状态信息，提高了用户的体验。
