以下，将结合附图对本公开示例实施例任务处理方法中包括的各步骤进行详细的解释以及说明。
首先，对本公开示例实施例的发明目的以及应用场景进行解释以及说明。具体的，本公开示例实施例提出了一种用于会议预约系统的网关软件实现方法，实现预约会议信息显示在无线终端门牌上。具体的，会议一体机和网关采用静态IP(Internet Protocol，网际互联协议)以太网直连，利用HTTP(HyperText Transfer Protocol，超文本传输协议)进行交互，为了保证节约连接资源，网关和会议一体机中的客户端(APP，应用程序)都既是httpServer，同时又是httpClient，网关和终端采用Lora无线通信。
进一步的，由于会议室的合理高效利用、占用以及预约信息提醒一直是一个长期存在的痛点，而随着电子设备智能化的提升，会议一体机或者电子白板也越来越成为会议室的标配，而利用网关和会议一体机的结合，再结合无线终端门牌，就可以组成一个智能化的会议预约显示系统。因此，本公开示例实施例基于此场景提供一种任务处理方法，通过网关和会议一体机以及显示终端之间的交互，从而实现通过会议一体机来预约会议，最终将会议预约信息发送到无线终端门牌，并在终端门牌上显示。
其次，对本公开示例实施例中所涉及到的任务处理系统进行解释以及说明。具体的，参考图2所示，该任务处理系统可以包括会议一体机210、网关220以及显示终端230，其中，会议一体机通过以太网与网关连接，网关通过Lora与显示终端连接，会议一体机中设置有客户端，用户可以通过会议一体机中设置的客户端进行会议预约；并且，在该任务处理系统中，一个网关中可以绑定一个或者多个会议一体机，也可以绑定一个或者多个显示终端，该显示终端为无线终端门牌，当然也可以是其他用于进行显示的显示终端，本示例对此不做特殊限制。
同时，参考图3所示，网关220中可以包括应用接口层301、管理接口层302以及通信接口层303，其中，通信接口层用于通过以太网与会议一体机连接，也即通信接口层用于主要是串口通信以及网口TCP通信的底层读、写、打开、关闭等接口；管理接口层用于实现本公开所记载的任务处理方法，也即管理接口层实现了终端设备管理、任务管理、白名单管理、日志管理、消息队列管理、配置文件管理；其中，终端设备管理 用于管理设备各种状态信息；任务管理用于管理任务链表，成功任务名单以及失败任务名单；白名单管理用于管理系统合法设备标识名单，只有在白名单里面的设备标识才可以加入系统；日志管理用于管理系统日志，以及日志分割等；消息队列管理用于管理上行以及下行数据消息；配置文件管理用于管理系统启动配置信息以及运行过程中的文件记录信息；应用接口层用于接收会议一体机发送的任务请求和/或向会议一体机发送数据获取请求，也即应用接口层实现了httpServer接口主要用于对会议一体机的GET以及POST等方法的响应，httpClient的接口主要用于连接会议一体机后从会议一体机上下载图片以及文字等数据文件。
进一步的，在本公开示例实施例的一种任务处理方法中：
在步骤S110中，接收会议一体机所在的客户端发送的任务请求，并对所述任务请求进行解析，得到所述任务请求中包括的待处理任务，以及与所述待处理任务对应的显示终端。
在本示例实施例中，首先，接收会议一体机所在的客户端发送的任务请求，具体的，可以包括：建立所述会议一体机所在的客户端与所述网关之间的Http连接，并基于所述Http连接接收所述会议一体机所在的客户端发送的任务请求；其中，所述任务请求是通过用户对所述客户端的显示界面显示的任务信息进行选择操作生成的。具体的，当用户需要进行会议预约、显示终端注册、程序升级或者底图更新时，可以通过会议一体机中包括的客户端选取对应的任务，客户端会根据用户选取的任务为该匹配对应的显示终端，进而生成对应的任务请求并发送至网关。
进一步的，当网关接收到该任务请求后，即可对该任务请求进行解析，进而得到任务请求中包括的待处理任务，以及与该待处理任务对应的显示终端；其中，该待处理任务包括会议预约任务、显示终端注册任务、OTA升级任务以及底图更新任务等等。此处需要补充说明的是，待处理任务也可以是其他任务，例如显示终端状态查询任务或者显示终端删除任务等等，本示例对此不做特殊限制。
在步骤S120中，根据所述显示终端的终端标识判断所述显示终端是否存在于预设的白名单列表中，并在确定所述显示终端存在于所述白名单列表中时，获取所述显示终端上报的心跳信息。
在本示例实施例中，为了可以避免由于突然断网连接造成的任务处理失败的问题，可以在网关中创建与该待处理任务对应的文件夹，进而使得网络畅通后，可以对该文件夹中的待处理任务进行处理，以避免任务漏处理或者重复处理的问题。具体的，该任务处理方法还可以包括：根据所述终端标识建立与所述显示终端对应的任务文件夹，并根据所述待处理任务确定所述任务文件夹的任务开始时间以及任务结束时间。
进一步的，当任务文件夹建立完成以后，即可进行具体的任务的处理过程。其中，参考图4所示，根据所述显示终端的终端标识判断所述显示终端是否存在于预设的白名单列表中，可以包括以下步骤：
步骤S410，计算当前时间节点与所述任务开始时间和/或所述任务结束时间之间的第一时间差和/或第二时间差，并判断所述第一时间差和/或第二时间是否满足预设条件；
其中，判断所述第一时间差和/或第二时间是否满足预设条件，可以包括：判断所述第一时间差和/或第二时间差是否大于第一预设阈值；其中，所述第一预设阈值为零；
步骤S420，若所述第一时间差和/或所述第二时间差满足预设条件，则根据所述终端标识判断所述显示终端是否存在于预设的白名单列表中。
其中，根据所述终端标识判断所述显示终端是否存在于预设的白名单列表中，还可以包括：首先，计算所述显示终端上报的上报终端标识与所述终端标识之间的差值；其次，在确定所述差值大于所述第一预设阈值时，根据所述终端标识判断所述显示终端是否存在于预设的白名单列表中。
以下，将对步骤S410-步骤S420进行解释以及说明。具体的，首先，在网关里面以终端标识{device_id}来创建与显示终端对应的任务文件夹，然后再根据待处理任务确定该任务文件夹的任务开始时间以及任务结束时间；例如，当待处理任务是会议预约任务时，可以根据该会于预约任务所需要的会议开始时间以及会议结束时间确定任务开始时间以及任务结束时间；当待处理任务是底图更新任务时，可以根据具体的更新时间确定任务开始时间以及任务结束时间等等。
进一步的，当任务文件夹创建完成后，可以在该任务文件夹下创建和维护一个task.ini文件。其中，Task.ini文件内容可以如下所示：
[task]
task_id＝"2"//任务序号
data_id＝"1"//数据序号
start_time＝2021-05-21 11:11:00//任务执行开始时间
end_time＝2021-05-21 11:11:00//任务执行结束时间
device_id＝"00A20001341A"//需要执行任务的终端ID
task_status＝0//任务执行状态
进一步的，采用创建任务文件夹的方式，当会议一体机中的应用程序建立针对多个显示终端执行的待处理任务且存在多个显示终端在同一个网关下工作时，会存储以相应终端标识{device_id}命名的任务文件夹。当时，该任务文件夹并非提前创立，而是通过POST数据创建任务时，根据device_id字段创建。
并且，当网关恢复网络连接以后，可以执行如下策略：一方面，对比当前时间节点和end_time(任务结束时间)之间的第一时间差，若第一时间差大于零，则认为该任务超时，即认为任务不存在，无需执行；另一方面，对比当前时间节点和start_time(任务开始时间)之间的第二时间差，若第二时间差大于零，则认为该待处理任务还未开始，该任务不存在，无需执行；再一方面，对比终端上报的上报终端标识与终端标识之间的差值，若差值为负数或者为0，则待处理任务不存在，否则存在。
进一步的，当任务文件夹创建完成以后，即可根据显示终端的终端标识判断显示终端是否存在于预设的白名单列表中，并在确定显示终端存在于所述白名单列表中时，获取显示终端上报的心跳信息。此处需要补充说明的是，当获取到心跳信息以后，可以根据该心跳信息的上报时间与当前时间之间的第三时间差来判断该显示终端是否一定在线，如果第三时间差过长，则可以等待显示终端在下一次上报心跳信息以后，再发送对应的目标任务；如果第三时间差在一定的范围内，则可以直接发送目标任务。通过该方法，可以确保任务可以准确的发送到对应的显示终端，进而提高任务下发的成功率。
在步骤S130中，根据所述心跳信息的确认信息以及所述待处理任务生成目标任务，并将所述目标任务发送至所述显示终端，以使得所述显示终端对所述目标任务进行处理。
在本示例实施例中，由于上述待处理任务可以包括多种情况，因此，以下通过图5-图8对具体的任务处理过程进行解释以及说明。
首先，参考图5所示，当所述待处理任务为会议预约任务时，根据所述心跳信息的确认信息以及所述待处理任务生成目标任务，并将所述目标任务发送至所述显示终端，以使得所述显示终端对所述目标任务进行处理，可以包括以下步骤：
步骤S510，根据所述心跳信息的确认信息以及所述会议预约任务中包括的会议开始时间、会议结束时间生成所述会议时间显示任务；
步骤S520，将所述会议时间显示任务发送至所述显示终端，以使得所述显示终端对所述会议开始时间以及会议结束时间进行显示。
以下，将对步骤S510以及步骤S520进行解释以及说明。具体的，首先，根据显示终端上报的心跳信息生成确认信息，然后再根据确认信息以及会议开始时间、会议结束 时间生成会议时间显示任务，再将该会议时间显示人物发送至显示终端，当该显示终端接收到该会议时间显示任务以后，对该会议时间显示任务进行解析进而得到会议开始时间以及会议结束时间，并在显示界面中对该会议开始时间以及会议结束时间进行显示，以完成会议预约任务。通过该方法，使得用户可以明确的根据显示终端上显示的会议开始时间以及会议结束时间来确定各个会议室的占用情况，进而可以在提高会议室的利用率的情况下，提升用户体验。
其次，参考图6所示，当所述待处理任务为显示终端的注册任务时，根据所述心跳信息的确认信息以及所述待处理任务生成目标任务，并将所述目标任务发送至所述显示终端，以使得所述显示终端对所述目标任务进行处理，可以包括以下步骤：
步骤S610，根据所述注册请求中包括的明文通用密钥计算所述显示终端的终端密钥，并根据所述终端密钥以及所述心跳信息的确认信息生成确认注册任务。
具体的，根据所述注册请求中包括的明文通用密钥计算所述显示终端的终端密钥，可以包括：首先，获取所述注册请求中包括的明文通用密钥，并判断所述明文通用密钥是否为合法密钥；其次，在确认所述明文通用密钥为合法密钥时，将所述明文通用密钥作为加密因子，并利用预设的加密算法对所述通用明文密钥进行计算，得到所述显示终端的终端密钥。
步骤S620，将所述确认注册任务发送至所述显示终端，以完成所述显示终端在所述网关侧的注册。
以下，将对步骤S610以及步骤S620进行解释以及说明。首先，为了可以完成显示终端的注册任务，需要从会议一体机中的客户端中获取第一显示中的终端标识，再将该终端标识添加至白名单列表中。具体的，该任务处理方法还包括：将所述显示终端的注册任务中包括的显示终端的终端标识添加至所述白名单列表，并接收所述显示终端发送的注册请求。也即，当网关从会议一体机上报的注册任务以后，可以将注册任务中包括的终端标识加入白名单列表，然后再开始设备注册过程。
其次，当网关接收到显示终端发送的注册请求以后，即可根据注册请求中包括的明文通用密钥计算显示终端的终端密钥。其中，在终端密钥的计算过程中，显示终端先发送一次明文通用秘钥，在网关验证该秘钥后合法后，回复终端注册成功的带着新的终端密钥；并且，在终端密钥的计算过程中，可以基于预设的对称加密算法(例如DES)或者预设的非对称加密算法(例如RSA或者DSA)进行计算，本示例对此不做特殊限定。
此处需要补充说明的是，通过利用两次秘钥验证，可以实现网关和显示终端的一一绑定，可以保证显示终端不会绑定到其他网关，而网关也只会过滤接收当前已经绑定的显示终端信息；同时，显示终端带着新的终端秘钥通过心跳定期上送显示终端的心跳信息，网关回复显示终端的心跳信息的确认信息，如果会议一体机下发给网关任务，那么网关在下次心跳后，回复显示终端有任务，显示终端准备接受任务，网关本地维护任务信息，并上报最终任务结果。通过该方法，可以在提高任务的完成效率的同时，降低网关的负担，并提高任务完成的成功率。
进一步的，参考图7所示，当所述待处理任务为OTA升级任务时，根据所述心跳信息的确认信息以及所述待处理任务生成目标任务，并将所述目标任务发送至所述显示终端，以使得所述显示终端对所述目标任务进行处理，可以包括以下步骤：
步骤S710，对所述OTA升级任务进行解析，得到所述OTA升级任务中包括OTA升级包的第一下载地址，并根据所述第一下载地址下载所述OTA升级包；
步骤S720，对所述OTA升级包的完整性以及安全性进行校验，并在确定所述OTA升级包完整且安全时，对所述OTA升级包进行解码；
具体的，对所述OTA升级包的完整性以及安全性进行校验，可以包括：首先，基于预设的信息摘要算法对所述OTA升级包的完整性进行校验；其次，在确定所述OTA 升级包为完整的数据包时，利用第一公钥对所述OTA升级包进行解密；最后，在确定解密结果为成功解密时，确定所述OTA升级包为安全的数据包。
步骤S730，对解码后的OTA升级包进行压缩，得到压缩数据包，并根据所述压缩数据包以及心跳信息的确认信息生成OTA升级任务；
步骤S740，将所述OTA升级任务包发送至所述显示终端，以使得所述显示终端根据所述OTA升级任务中的压缩数据包对所述显示终端中包括的程序进行更新。
以下，将对步骤S710-步骤S740进行解释以及说明。具体的，当网关接收到会议一体机中包括的客户端推送的OTA(Over-the-Air Technology，空中下载技术)升级任务的时候，任务信息中会携带任务的OTA升级包的第一下载地址以及大小等信息；在具体执行过程中，网关作为httpClient来连接会议一体机中的客户端，进而从客户端下载OTA升级包，然后根据接收到的OTA任务信息进行三个步骤的校验：首先，数据完整性校验，比如MD5算法校验，数据完整性校验是为了保证下载的数据格式以及大小正确；其次，为了网络传输的安全，进行数据安全性校验；具体的，由于OTA数据包进行了私有秘钥的加密，所以需要解密验证；如果解密成功，则证明OTA数据包安全，否则不安全；最后为，了更好的在网络传输OTA升级包，所以需要base64编解码，并对解码后的OTA升级包进行压缩，得到压缩数据包；最后，再将该压缩数据包发送至显示终端，进而使得显示终端根据该压缩数据包对程序进行更新。
其中，OTA任务信息具体可以如下所示：
Figure PCTCN2022114267-appb-000001
此处需要补充说明的是，通过上述所记载的方法进行更新，可以在确保程序的更新效率的基础上，确保系统的安全性以及程序更新的成功率。
最后，参考图8所示，当所述待处理任务为底图更新任务时，根据所述心跳信息的确认信息以及所述待处理任务生成目标任务，并将所述目标任务发送至所述显示终端，以使得所述显示终端对所述目标任务进行处理，可以包括以下步骤：
步骤S810，对所述底图更新任务进行解析，得到待更新底图的第二下载地址，并根据所述第二下载地址对所述待更新底图进行下载；
步骤S820，根据所述待更新底图以及所述心跳信息的确认信息以及所述待处理任务生成底图更新任务；
步骤S830，将所述底图更新任务发送至所述显示终端，以使得所述显示终端根据所述底图更新任务中包括的待更新底图对所述显示终端中的底图进行更新。
在图8所示出的方法中，由于可以直接通过网关对该网关下绑定的显示终端的底图更新任务进行分配，进而实现显示终端中的待更新底图的更新，进而可以在降低网关负担的情况下，提高底图更新的效率。
此处需要进一步补充说明的是，在图5-图8所示出的具体的任务处理过程中，由于会议一体机和网关采用静态IP以太网直连，利用Http协议进行交互；因此，对于网关的通用扩展设计上，网关既要可以和会议一体机中包括的客户端之间进行离线的数据传输，同时也要具备和云服务器之间的在线传输框架设计，而为了节约连接资源，网关和 会议一体机中包括的客户端都既是httpServer，同时又是httpClient，用完就断开连接，节约服务端连接资源。
更进一步的，当任务处理完成后，该任务处理方法还可以包括：首先，接收所述显示终端在对会议预约任务和/或显示终端注册任务和/或OTA升级任务和/或底图更新任务完成后，发送的任务反馈信息；其次，根据所述任务反馈信息以及所述会议预约任务的第一任务标识和/或显示终端注册任务第二任务标识和/或OTA升级任务的第三任务标识和/或底图更新任务的第四任务标识，生成任务反馈链表。其中，在任务反馈链表中，可以包括任务成功链表和任务失败链表，通过设置该链表，可以准确的对各任务的处理情况进行查看，并在查看到任务处理失败后，及时的根据失败原因进行对应的调整。
以下，结合图9对本公开示例实施例的任务处理方法进行进一步的解释以及说明。参考图9所示，该任务处理方法可以包括以下步骤：
步骤S901，会议一体机根据用户对显示界面上的各交互控件的选择操作生成任务请求，并将该任务请求发送至网关；
步骤S902，网关接收任务请求，对任务请求进行解析，得到任务请求中包括的待处理任务，以及与待处理任务对应的显示终端；
步骤S903，网关根据显示终端的终端标识判断显示终端是否存在于预设的白名单列表中；
步骤S904，网关在确定显示终端存在于白名单列表中时，获取显示终端上报的心跳信息；
步骤S905，网关根据心跳信息的确认信息以及待处理任务生成目标任务，并将目标任务发送至显示终端；
步骤S906，显示终端接收目标任务，并对目标任务进行处理。
本公开示例实施例所提供的任务处理方法，由于任务的生成以及分配都是通过网关进行实现，进而可以保证即使在网关和服务器断开连接的情况下，网关仍然可以管理显示终端的任务，进而提高了任务的处理效率以及任务处理的及时性。
