Description

多媒体信息处理方法、装置和乘客信息系统
相关申请的交叉引用
本公开要求比亚迪股份有限公司于2018年02月09日提交的、申请名称为“多媒体信息处理方法、装置和乘客信息系统”的、中国专利申请号“201810136685.0”的优先权。
技术领域
本公开涉及轨道交通技术领域，尤其涉及一种多媒体信息处理方法、装置和乘客信息系统。
背景技术
在城市轨道交通行业中，通过乘客信息系统(Passenger Information System，以下简称PIS)为乘客提供多样化多媒体信息服务，例如可以提供列车运营信息、网络运营信息、便民信息或紧急疏散信息等信息。
目前PIS具有“一线一中心”和“多线共用线路中心”两种运营管理模式。其中，“一线一中心”的单线运营管理模式为：每条线路的PIS独立招标、建设和运营，从软件到硬件都需要进行开发设计。不同线路控制中心的控制系统不互联互通，当业务功能改变时，需要针对每一个线路控制中心进行重新部署。
“多线共用线路中心”的网络化运营管理模式为：多条线路共用一个线路控制中心，但各业务功能在线路控制中心控制系统的子系统中实现，与控制系统绑定紧密。所以一旦业务功能改变，仍需要将控制系统代码重新设计。
发明内容
本公开提出一种多媒体信息处理方法、装置和乘客信息系统，该乘客信息系统中所有的业务功能均是在SaaS数据中心实现的，而运营中心只是以租户的形式租用乘客信息系统中的软件。乘客信息系统可以为各线路提供统一的SaaS服务，从而各运营中心到车站或列车无需进行任何的软件开发，可以降低开发和运维成本。此外，系统架构上从运营中心-车站-地面设备端的三级架构改变为运营中心-地面设备端的两级架构，可以简化系统的层级，降低系统的复杂度。当运营中心的业务功能变更时，只需在SaaS数据中心中进行软件代码的修改，操作方便，扩展性较高，从而无需对运营中心的控制系统重新部署内部子系统， 进而可以避免在子系统重新部署的过程中出现列车运营停滞的问题。而且不同的运营中心之间可以实现互联互通，数据统一由SaaS数据中心管理，可以为未来的大数据或策略支持系统提供数据支持，用于解决现有技术中在单线运营模式和网络运营模式下的PIS，建设完成后，一旦有业务功能增加或变更时，调整难度比较大，扩展性不高，不利于PIS的长期建设发展的技术问题。
本公开第一方面实施例提出了一种乘客信息系统，包括：软件即服务SaaS数据中心、多个地面设备端和至少一个运营中心；
所述运营中心，与所述SaaS数据中心通信，用于获取线路计划，向所述SaaS数据中心发送用于执行所述线路计划所需的媒体运营信息；
所述SaaS数据中心，与所述多个地面设备端通信，用于对所述媒体运营信息进行数据处理，得到各地面设备端的媒体运营计划，并向对应的地面设备端发送所述媒体运营计划；
所述地面设备端，设置于车站或列车的车厢，用于将所述媒体运营计划进行多媒体展示。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
在城市轨道交通行业中，通过乘客信息系统(Passenger Information System，以下简称PIS)为乘客提供多样化多媒体信息服务，例如可以提供列车运营信息、网络运营信息、便民信息或紧急疏散信息等。PIS系统包括运营控制中心(Operating Control Center，简称OCC)系统、车站子系统、车载子系统、网络子系统，其中，OCC系统负责媒体设计、多媒体编播管理、地面设备播放监控、对外接口等功能；车站子系统负责从OCC系统中接收并同步数据、运营信息的发布或解除、播控器播放的功能；车载子系统负责数据接收、显示和播放、车载视频监控和车载广播的功能；网络子系统为PIS系统提供网络传输支持。
目前具有“一线一中心”和“多线共用线路中心”两种运营管理模式。其中，“一线一中心”的单线运营管理模式为：每条线路的PIS独立招标、建设和运营，从软件到硬件都需要进行开发设计。这种模式下，由于不同的线路PIS单独招标建设，即使在设计需求相同的情况下，不同的供应商采用的技术方案、技术平台各不相同，导致接口定义不统一，从而不同线路中心的控制系统不互联互通。当业务功能改变时，需要针对每一个线路控制中心进 行重新部署。
“多线共用线路中心”的网络化运营管理模式为：多条线路共用一个线网中心，在一定程度上减少了多线路的重复性功能建设，而且在接口上也实现了统一。但是“多线共用线路中心”只是将多个线网中心减少到一个，而在系统的部署上仍然没有优化，从控制中心到车站、列车需要部署相应的软件系统，整个软件架构上仍然是客户端/服务器模式，用户通过操作各子系统的客户端完成其业务功能。由于各业务功能在线路控制中心控制系统的子系统中实现，与控制系统绑定紧密。所以一旦业务功能改变，仍需要将控制系统代码重新设计，难以灵活扩展。此外，在子系统重新部署的过程中，将造成列车运营的停滞，不利于列车运营的管理。
为了解决现有技术中乘客信息系统开发成本和运维成本较高、系统架构复杂，以及系统中有业务功能变更时，需要解决控制系统代码重新设计，难以灵活扩展的问题，本公开实施例中，乘客信息系统基于软件即服务(Software-as-a-Service，简称SaaS)，乘客信息系统以租用的方式提供SaaS服务给各个运营中心，各个运营中心是乘客信息系统的不同的租户。其中，乘客信息系统包括：SaaS数据中心、多个地面设备端和至少一个运营中心，运营中心与SaaS数据中心通信，当运营中心的业务功能变更时，只需在SaaS数据中心中修改相应的软件代码，而无需对运营中心的控制系统重新部署内部子系统。
本公开实施例中，乘客信息系统中所有的业务功能均是在SaaS数据中心实现的，而运营中心只是以租户的形式租用乘客信息系统中的软件。乘客信息系统可以为各线路提供统一的SaaS服务，从而各运营中心到车站或列车无需进行任何的软件开发，可以降低开发和运维成本。此外，系统架构上从运营中心-车站-地面设备端的三级架构改变为运营中心-地面设备端的两级架构，可以简化系统的层级，降低系统的复杂度。当运营中心的业务功能变更时，只需在SaaS数据中心中进行软件代码的修改，操作方便，扩展性较高，从而无需对运营中心的控制系统重新部署内部子系统，进而可以避免在子系统重新部署的过程中出现列车运营停滞的问题。由于业务处理是在SaaS数据中心实现的，地面设备端只需配备视频播放器和播控器，而无需部署任何其他设备，可以进一步降低系统的复杂度。而且不同的运营中心之间可以实现互联互通，数据统一由SaaS数据中心管理，可以为未来的大数据或策略支持系统提供数据支持。
下面参考附图描述本公开实施例的多媒体信息处理方法、装置和乘客信息系统。
图1为本公开实施例一所提供的乘客信息系统的结构示意图。

本公开实施例中，运营中心130中的各线路控制中心可以包括对应不同访问权限的工作站，工作站用于登录对应的用户账号，根据用户账号对应的访问权限访问SaaS数据中心110；其中，访问权限指示了允许调用的能力组件。也就是说，当运营中心130登录用户账号或访问SaaS数据中心110时，SaaS数据中心110需对运营中心130进行身份校验和访问权限查询，以根据用户账号所具有的访问权限，向运营中心130发送Web页面，即各运营中心130只能够看到被允许访问的页面或菜单。
作为一种可能的实现方式，运营中心130通过web页面，向SaaS数据中心110发送的媒体运营信息中可以直接携带视频或图片，当SaaS数据中心110通过访问接口从运营中心获取媒体运营信息后，可以直接从媒体运营信息中获取视频或图片，从而根据获取的视频或图片，生成各地面设备端120的媒体运营计划。
作为另一种可能的实现方式，运营中心130向SaaS数据中心110发送的媒体运营信息可以指示相应的视频或图片，例如，媒体运营信息中可以包括相应的视频或图片的标识信息、存储地址等信息，当SaaS数据中心110通过访问接口从运营中心130获取媒体运营信息后，可以从预存的资源中，根据视频或图片的标识信息获取媒体运营信息指示的视频或图片，从而根据获取的视频或图片，生成各地面设备端120的媒体运营计划。
本公开实施例中，当运营中心130的业务功能变更时，只需在SaaS数据中心110中修改相应的软件代码，操作方便，扩展性较高，从而无需对运营中心的控制系统重新部署内部子系统，进而可以避免在子系统重新部署的过程中出现列车运营停滞的问题。当修改SaaS数据中心110中的软件代码后，可以通过修改后的能力组件对媒体运营信息执行业务处理，得到对应的媒体运营计划。
地面设备端120，设置于车站或列车的车厢，用于将媒体运营计划进行多媒体展示。
