具体实施方式
下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。
为使本发明实施例的目的、技术方案和优点更加清楚，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。
图1为终端设备通过网关将终端注册信息传输到系统平台进行注册的信令流程图，具体注册过程如下：
首先终端设备向网关发送注册请求消息，其中注册请求消息中携带注册信息，注册信息中包括终端设备的ID信息、终端设备的认证信息以及终端设备的类型和终端设备中的数据类型等。网关接收到终端设备的注册请求消息后，向终端设备返回与注册请求消息对应的第一响应信息。并且，将携带注册信息的注册请求消息转发至系统平台，系统平台在接收到注册请求消息后，从注册请求消息中获取注册信息。并根据注册信息对终端设备进行认证。认证成功后，向网关返回认证成功的第二响应信息。网关则将第二响应信息转发给终端设备。当然，如果注册失败，系统平台也要返回第三响应信息，网关将第三响应信息反馈给终端设备。
应理解，终端设备将注册请求消息传输到网关，然后通过网关转发到系统平台，系统平台根据注册请求消息中的注册信息对终端设备进行注册的过程只执行一次即可。并不是在每次根据数据传输规则传输数据时，均要执行一次。而注册过程是在数据传输之前就必须执行的过程，因此，本实施例中首先概括的介绍了终端设备注册到系统平台的执行过程。
需要说明的是，终端注册到系统平台可以包括两种方式，一种是终端通过网关注册到系统平台(具体过程如上文所述)。另一种方式是终端设备直接注册到系统平台，而不经过网关这个节点。具体执行的过程与上文中通过网关注册类似，只不过是没有网关作为中介，详细过程这里不再赘述。
而在下文中，将从两种方式介绍数据传输的具体过程。
图2为本发明实施例一提供的一种数据传输系统中各部件之间传输数据的信令流程图 200，其中该系统中包括系统平台和终端设备，具体工作过程如下：
步骤210，根据终端设备的类型和终端设备产生的数据类型，确定终端设备产生数据的数据传输规则。
具体的，终端设备的注册信息中包括终端设备的ID信息、终端设备的认证信息以及终端设备的类型和终端设备中的数据类型等。因此，在系统平台获取到终端设备的注册信息后，就可以确定终端设备的类型和终端设备的数据类型。
根据终端设备的类型和终端设备产生的数据的类型，可以确定终端设备的优先等级，而根据数据的优先等级，确定数据传输规则。其中，数据传输规则可以包括数据传输的优先等级和数据传输方式。
设备类型可以包括重点监测设备、普通监测设备、受限监测设备和不监测设备。数据类型可以包括设备管理数据、实时数据以及日志数据等等。如某一重点监测设备的日志数据的优先等级，一定低于普通监测设备的报警数据的优先等级。还可以将数据的优先等级以数值形式具体体现。例如，数据的优先等级设定为1-9级。将高优先级的数据等级设定为7-9级，而普通优先级的数据等级设定为4-6级，而低优先级的数据设定等级为1-3级。具体根据设备类型和数据类型，确定数据优先级的表现形式可以用表1表示：
Figure PCTCN2017082041-appb-000001
并且当数据的等级低于第一预定阈值(例如第一预定阈值为4)时，则设定终端设备不主动将数据传输到系统平台，而是在系统平台向终端设备发送查询消息时，终端设备才会将该数据发送到系统平台。
而在设定数据优先等级后，数据传输方式可以包括：对于7-9级的数据，终端设备则会周期性的将数据上传到系统平台。
对于4-6级的数据，终端设备会在系统平台指定的时间，统一打包上传到系统平台。
对于1-3级的数据，仅在系统平台查询消息时，终端设备才会将该数据发送到系统平台。
在数据传输规则中，在固定的时间段内，将不同等级的数据传输到系统中，这样就可以避免的了系统平台在同一时间段接收大量的数据，导致系统性能下降的问题。
但是，终端设备的数据不可能是一直处于稳定的，也可能会在某一时间段内发生大的浮动，此时就不能再按照上述说介绍的数据传输规则，等到传输该数据的时间段时，再将该数据传输到系统平台进行处理。而是需要立即将该数据传输到系统平台，以方便系统平台立即处理该数据。例如，温度传感器检测到市内温度突然从20摄氏度变化到60摄氏度，此时可能是室内发生火灾或者某些设备发生故障等，终端设备需要立即读取该数据，并将该数据发送至系统平台，方便系统平台对此做出相应的处理。因此，在本发明的实施例中， 数据传输规则还可以包括：数据提前上报规则。该数据提前上报规则用于，当终端设备检测到数据的浮动变化数值大于第二预定阈值时，立即将数据传输到系统平台。
步骤220，系统平台向终端设备发送数据传输消息。
具体的，数据传输消息中携带数据传输规则，以便终端设备根据数据传输规则，将与数据传输规则对应的数据发送至系统平台。
可选的，可以在数据传输消息中增加新的头域，该头域中包含第一指示信元，用于指示数据传输的优先等级；
或者，也可以在数据传输消息的头域中存入指示数据优先等级的第二指示信元。
步骤230，终端设备接收系统平台发送的数据传输消息，其中，数据传输消息携带数据传输规则。
步骤240，终端设备根据数据传输规则，将与数据传输规则对应的数据发送至系统平台。
具体的，根据数据传输规则，可以确定系统平台所要获取的数据，以及如步骤220中所介绍的具体传输数据的方式(包括周期性的传输的数据、固定时间段内传输的数据以及不主动发送的数据等等)。
终端设备只要在系统平台所规定的时间，将此时系统平台所要获取的数据传输到系统平台即可。
而在传输的过程中，数据传输的优先等级还要依赖于数据的优先等级。例如传输高优先级数据时，因为高优先级数据的数据优先等级为7-9级。在数据传输过程中，则需要先将数据优先等级为9级的数据传输到系统平台，然后再将优先等级为8级的数据传输到系统平台，最后是将优先等级为7的数据传输到系统平台。类似的，其他等级的数据，同样是相对而言，比较高的优先级的数据传输完毕之后，再传输低优先等级的数据。
在一个具体的例子中，假设终端设备包括了一个锅炉温度传感器、普通用户家里的电表、还有用户家里的温度传感器。这些终端设备直接将自身的注册请求消息发送到系统平台，当系统平台认证成功后，即注册到系统平台。系统平台根据每一个终端设备的注册信息，确定了终端设备的类型。并且，根据每一个终端设备的类型以及每一个终端设备产生的数据的类型，为其制定相应的数据传输规则。例如，锅炉温度传感器。锅炉本身是一种能量转换设备，锅炉中产生的热水或蒸汽可直接为工业生产和人民生活提供所需热能，也可通过蒸汽动力装置转换为机械能，或再通过发电机将机械能转换为电能。时刻监测锅炉的温度是十分必要的，因为一旦锅炉温度高到一定程度，可能会发生爆炸，造成机器损坏，严重的甚至会给工作人员造成人身伤害。所以，锅炉温度传感器，应该是一个重点监测的设备。锅炉温度传感器所检测的温度数据同样是重要的数据。因此，根据终端设备的类型和数据类型，可以确定锅炉温度传感器所检测的温度数据为7-9级的重点监测数据。而普通用户家里的电表所检测的数据，则可以定期的上传到系统平台，方便系统统计用户在固定时间段内所用电量，及时通知用户上缴电费。因此，可以将该类数据归类为4-6级的普通监测数据。而用户室内的温度传感器，用来检测室内温度的。一般而言，室内温度变化幅度不会很大，无需实时传输到系统平台。只需在系统平台查询时，终端设备将数据上传到系统平台即可，因此可以归类为1-3级的低优先级的数据。
在传输上述数据时，例如，在同一时刻，终端设备需要向系统平台传输当前锅炉温度传感器中的温度数据，还要传输电表中一个月之内的电量总量数据。锅炉温度传感器中的 温度数据的优先等级高于电表中电量数据的优先等级，因此，会优先传输锅炉温度传感器中的温度数据，然后再传输电表中的电量数据。
在另外一种情况中，由上文可知，用户室内温度传感器获取的温度数据算是低优先级的数据，一般而言，终端设备不会主动传输到系统平台。但是，一旦室内温度传感器检测到室内温度从20℃突然升高到60℃时，说明室内温度浮动变化值已经超过一定的阈值(例如10℃)。温度急剧升高就有发生火灾的危险。终端设备一旦确定温度传感器检测室内温度从20℃上升到60℃，就会立即将该信息上传到系统平台，以便系统平台及时处理该事件。
本发明实施例一提供的一种数据传输方法，系统平台将会根据已经注册的终端设备设备的类型以及终端设备产生的数据的类型，设定数据传输规则，包括数据传输的优先等级、数据传输形式以及提前上报规则等等。对于通过设置数据传输规则，可以有效的避免大量的数据传输到系统平台，而且还可以优先处理优先等级高的数据，提高系统的性能。
在另一种情况中，终端设备还可以通过网关，与系统平台建立通信连接。具体终端设备通过网关和系统平台建立交互的过程如图3所示。图3为本发明实施例二提供的另一种数据传输系统中各部件之间传输数据的信令流程图300，其中该系统中包括系统平台、网关和终端设备，具体工作过程如下：
步骤310，系统平台根据终端设备的类型和终端设备产生的数据的类型，确定网关传输数据的数据传输规则。
具体的，终端设备的注册信息中包括终端设备的ID信息、终端设备的认证信息以及终端设备的类型和终端设备中的数据类型等。因此，在系统平台获取到终端设备的注册信息后，就可以确定终端设备的类型和终端设备的数据类型。
根据终端设备的类型和终端设备产生的数据的类型，可以确定终端设备的优先等级，而根据数据的优先等级，确定数据传输规则。其中，数据传输规则可以包括数据传输的优先等级和数据传输方式。
设备类型可以包括重点监测设备、普通监测设备、受限监测设备和不监测设备。数据类型可以包括设备管理数据、实时数据以及日志数据等等。如某一重点监测设备的日志数据的优先等级，一定低于普通监测设备的报警数据的优先等级。还可以将数据的优先等级以数值形式具体体现。例如，数据的优先等级设定为1-9级。将高优先级的数据等级设定为7-9级，而普通优先级的数据等级设定为4-6级，而低优先级的数据设定等级为1-3级。具体根据设备类型和数据类型，确定数据优先级的表现形式可以用表1表示：
Figure PCTCN2017082041-appb-000002
并且当数据的等级低于第一预定阈值(例如第一预定阈值为4)时，则设定网关不主动将数据传输到系统平台，而是在系统平台向网关发送查询消息时，网关才会将该数据发送 到系统平台。
而在设定数据优先等级后，数据传输方式可以包括：对于7-9级的数据，则按照周期性的将数据上传到系统平台。
对于4-6级的数据，则在系统平台指定的时间，统一打包上传到系统平台。
对于1-3级的数据，仅在系统平台查询消息时，网关才会将该数据发送到系统平台。
在数据传输规则中，按照数据的优先等级，可以在固定的时间段内，将不同的数据传输到系统中，这样就可以避免的了系统平台在同一时间段接收大量的数据，导致系统性能下降的问题。
但是，终端设备的数据不可能是一直处于稳定的，也可能会在某一时间段内发生大的浮动，此时就不能再按照上述说介绍的数据传输规则，等到传输该数据的时间时，再将该数据传输到系统平台进行处理。而是需要立即将该数据传输到系统平台，以方便系统平台立即处理该数据。例如，温度传感器检测到市内温度突然从20摄氏度变化到60摄氏度，此时可能是室内发生火灾或者某些设备发生故障等，网关需要立即读取该数据，并将该数据发送至系统平台，方便系统平台对此做出相应的处理。因此，在本发明的实施例中，数据传输规则还可以包括：数据提前上报规则。该数据提前上报规则用于，当网关检测到数据的浮动变化数值大于第二预定阈值时，立即将数据传输到系统平台。
步骤320，系统平台向网关发送数据传输消息。
具体的，数据传输消息中携带数据传输规则，以便网关根据数据传输规则，从终端设备中获取与数据传输规则对应的数据，并发送至系统平台。
可选的，可以在数据传输消息中增加新的头域，该头域中包含第一指示信元，用于指示数据传输的优先等级；
或者，也可以在数据传输消息的头域中存入指示数据优先等级的第二指示信元。
步骤330，网关接收系统平台发送的数据传输消息，其中，数据传输消息携带数据传输规则。
步骤340，根据数据传输规则，从终端设备中获取与数据传输规则对应的数据，并发送至系统平台。
具体的，根据数据传输规则，可以确定系统平台所要获取的数据，以及如步骤310中所介绍的具体传输数据的方式等。
网关只要在系统平台所规定的时间，从终端设备中获取此时系统平台所要获取的数据，并将该数据传输到系统平台即可。
而在传输的过程中，数据传输的优先等级还要依赖于数据的优先等级。例如传输高优先级数据时，因为高优先级数据的数据优先等级为7-9级。在数据传输过程中，则需要先将数据优先等级为9级的数据传输到系统平台，然后再将优先等级为8级的数据传输到系统平台，最后是将优先等级为7的数据传输到系统平台。类似的，其他等级的数据，同样是相对而言，比较高的优先级的数据传输完毕之后，再传输低优先等级的数据。
需要说明的是，由上文可知，对于网关不主动上传的数据，例如低优先级的数据，是在系统平台需要查询时，网关再将该数据发送至系统平台。而对应查询上报的数据，网关还可以设置查询参数，该查询参数可以是在时间上和空间上设置的参数。例如在时间上，网关只存储3个月内获取的低优先级的数据。当3个月的时间过后，再获取的新数据则会 覆盖前3个月内所获取的数据。又或者，在空间上，网关为低优先级的数据设置固定的存储空间。存储空间已经占满时，若果再有新的数据需要存储，网关将会将新的数据覆盖之前存储的数据。
对应的，网关在上报系统平台所要查询的数据时，可以分为两类。系统平台向网关发送查询消息时，可以携带第三指示信元，该第三指示信元用于指示网关传输当前消息或者终端设备的最新消息。
当第三指示信元指示网关当前消息时，网关则直接在回复系统平台的响应消息中携带网关当前保存的终端设备的数据信息。
当第三指示信元指示设备的最新消息时，则网关需要到终端设备查询最新的数据信息，然后在回复系统平台的响应消息中携带终端设备的最新数据信息。
可选的，当网关在当前检测到某一终端设备的数据浮动值大于第二预定阈值时，则不会按照数据传输规则，等到传输该数据的时间时，再将该数据传输到系统平台进行处理。而是需要根据数据提前上报规则，立即将该数据传输到系统平台，以方便系统平台立即处理该数据。
在一个具体的例子中，假设终端设备包括了一个锅炉温度传感器、普通用户家里的电表、还有用户家里的温度传感器。这些终端设备通过网关，将自身的注册请求消息发送到系统平台，当系统平台认证成功后，即注册到系统平台。系统平台根据每一个终端设备的注册信息，确定了终端设备的类型。并且，根据每一个终端设备的类型，为其制定相应的数据传输规则。例如，锅炉温度传感器。锅炉本身是一种能量转换设备，锅炉中产生的热水或蒸汽可直接为工业生产和人民生活提供所需热能，也可通过蒸汽动力装置转换为机械能，或再通过发电机将机械能转换为电能。时刻监测锅炉的温度是十分必要的，因为一旦锅炉温度高到一定程度，可能会发生爆炸，造成机器损坏，严重的甚至会给工作人员造成人身伤害。所以，锅炉温度传感器，应该是一个重点监测的设备。锅炉温度传感器所检测的温度数据同样是重要的数据。因此，根据终端设备的类型和数据类型，可以确定锅炉温度传感器所检测的温度数据为7-9级的重点监测数据。而普通用户家里的电表所检测的数据，则可以定期的上传到系统平台，方便系统统计用户在固定时间段内所用电量，及时通知用户上缴电费。因此，可以将该类数据归类为4-6级的普通监测数据。而用户室内的温度传感器，用来检测室内温度的。一般而言，室内温度变化幅度不会很大，无需实时传输到系统平台。只需在系统平台查询时，网关将数据上传到系统平台即可，因此可以归类为1-3级的低优先级的数据。
在传输上述数据时，例如，在同一时刻，网关需要向系统平台传输当前锅炉温度传感器中的温度数据，还要传输电表中一个月之内的电量总量数据。锅炉温度传感器中的温度数据的优先等级高于电表中电量数据的优先等级，因此，会优先传输锅炉温度传感器中的温度数据，然后再传输电表中的电量数据。
在另外一种情况中，由上文可知，用户室内温度传感器获取的温度数据算是低优先级的数据，一般而言，网关不会主动传输到系统平台。但是，一旦室内温度传感器检测到室内温度从20℃突然升高到60℃时，说明室内温度浮动变化值已经超过一定的阈值(例如10℃)。温度急剧升高就有发生火灾的危险。网关一旦确定温度传感器检测室内温度从20℃上升到60℃，就会立即将该信息上传到系统平台，以便系统平台及时处理该事件。
本发明实施例二提供的一种数据传输方法，系统平台将会根据已经注册的终端设备设备的类型和终端设备产生的数据类型，设定数据传输规则，包括数据传输的优先等级、数据传输形式以及提前上报规则等等。对于通过设置数据传输规则，可以有效的避免大量的数据传输到系统平台，而且还可以优先处理优先等级高的数据，提高系统的性能。
与本发明实施例一提供的数据传输方法相对应的，本发明实施例三提供了一种数据传输装置，该数据传输装置主要与数据传输系统中的系统平台相对应，具体如图4所示，图4为本发明实施例提供的一种数据传输装置结构示意图400。该装置包括：处理模块401和发送模块402。
处理模块401，用于根据终端设备的类型和终端设备产生的数据类型，确定终端设备产生数据的数据传输规则。
具体的，处理模块401根据终端设备的类型和终端设备中的数据类型，确定终端设备产生的数据的优先等级，根据数据的优先等级，确定数据传输规则。其中，数据传输规则可以包括数据传输优先等级和数据传输方式。
可选的，当数据的优先等级小于第一预定某一设定阈值时，处理模块401具体用于：设定终端设备仅在系统平台查询数据时，将数据上传至系统平台。
在数据传输规则中，在固定的时间段内，将不同等级的数据传输到系统中，这样就可以避免的了系统平台在同一时间段接收大量的数据，导致系统性能下降的问题。
但是，终端设备的数据不可能是一直处于稳定的，也会在某一时间段内发生大的浮动，此时就不能再按照上述说介绍的数据传输规则，等到传输该数据的时间段时，再将该数据传输到系统平台进行处理。而是需要立即将该数据传输到系统平台，以方便系统平台立即处理该数据。例如，温度传感器检测到市内温度突然从20摄氏度变化到60摄氏度，此时可能是室内发生火灾或者某些设备发生故障等，终端设备需要立即读取该数据，并将该数据发送至系统平台，方便处理模块401对此做出相应的处理。因此，在本发明的实施例中，数据传输规则还可以包括：数据提前上报规则。该数据提前上报规则用于，当终端设备检测到数据的浮动变化数值大于第二预定阈值时，立即将数据传输到系统平台。
此外，处理模块401还用于，在数据传输消息中增加头域，头域中包含指示信元，指示信元用于指示数据的优先等级。
发送模块402，用于向终端设备发送数据传输消息，其中，数据传输消息中携带数据传输规则，以便终端设备根据数据传输规则，将与数据传输规则对应的数据发送至系统平台。
