参阅图1,本申请实施例的系统框架包括:
调用设备101至102,服务设备103至104。
调用设备101至102可以通过连接通道和服务设备103至104间进行信息传输,连接通道可以为数据通道或命令通道,数据通道为调用设备101至102和服务设备103至104之间进行信息传输的双向通道,命令通道为调用设备101至102向服务设备103至104进行信息传输的单向通道。

本实施例仅以两个调用设备,和两个服务设备为例进行说明,可以理解的是,本申请实施例中,调用设备和服务设备的个数不做限定。
请参阅图2,本实施例中,调用设备和服务设备均可支持HiStreaming协议(HiStreaming protocol,HISTM),具体的,调用设备和服务设备支持的协议可以包括受限应用协议(constrained application protocol,COAP),简单服务发现协议(simple service discovery protocol,SSDP)等,调用设备和服务设备可以基于这些共同支持的协议进行相应的信息传输。
调用设备对服务设备的功能的调用可以是设备级别的调用,例如,一个调用设备可以同时调用多个服务设备的功能,一个服务设备也可以同时被多个调用设备进行功能调用。
需要说明的是,调用设备对服务设备的功能的调用也可以是业务级别的调用,调用设 备上可以运行有一种或多种业务,多种业务可以同时调用服务设备的一种功能,一种业务也可以同时调用服务设备的多种功能。
本实施例中,调用设备和服务设备之间的信息传输可以包含不同的流程,下面分别进行介绍:
一、功能调用流程:
请参阅图3,本实施例中,调用设备可以通过连接通道调用服务设备所能提供的AI功能,下面进行详细说明:
301、HISTM Server设备向HISTM Client设备发送设备信息;
本实施例中,以HISTM Server设备作为服务设备为例进行说明,以HISTM Client设备作为调用设备为例进行说明。
可以理解的是,在实际应用中,调用设备和服务设备还可以是其他类型的设备,例如调用设备可以为电视、机顶盒、扫地机器人或智能音响等,服务设备可以为摄像设备、智能门铃或家庭智能计算中心等,具体此处不做限定。
HISTM Server设备上线后,向HISTM(具体可以为SSDP)中注册设备信息,注册完成后,HISTM(具体可以为SSDP)将设备信息组播到所在网络,则在网络中的HISTM Client设备可以获取到设备信息,并感知到HISTM Server设备上线。
需要说明的是,HISTM Server设备可以是直接通过HISTM在网络内组播自身的设备信息,也可以是通过HISTM将自身的设备信息注册到网络中的某一服务器,再由该服务器在网络内组播该设备信息,具体此处不做限定。
本实施例中,HISTM Server设备的设备信息可以包括设备名、网际协议(internet protocol,IP)地址信息和接入的端口号(Port)等用以识别该HISTM Server设备的信息。
当有多个HISTM Server设备上线时,各HISTM Server设备均会按照上述流程发送设备信息。
302、HISTM Client设备将获取到的设备信息保存至SSDP设备列表;
当HISTM Client设备感知到HISTM Server设备上线时,可以将获取到的该HISTM Server设备的设备信息保存至本地存储的设备列表中。
303、HISTM Client设备获取HISTM Server设备的能力信息;
当HISTM Client设备收到多个HISTM Server设备的设备信息之后,HISTM Client设备可以通过COAP轮询本地存储的设备列表中各HISTM Server设备的能力信息。
在一种可选的情况中,在HISTM Client设备获取HISTM Server设备的能力信息之前,HISTM Client设备先确定要搜索的HISTM Server设备的设备名,然后确定设备列表中设备名符合需求的所有HISTM Server设备,进一步的,HISTM Client设备通过COAP轮询该设备名符合需求的所有HISTM Server设备,并获取这些设备名符合需求的HISTM Server设备的能力信息。
例如HISTM Client设备确定要搜索的HISTM Server设备的设备名为包含CameraVideo的名称,则HISTM Client设备可以从设备列表中选择出设备名包含CameraVideo的HISTM Server设备,例如可以是CameraVideo0、CameraVideo3等。
选择出设备名符合需求的所有HISTM Server设备之后,HISTM Client设备再通过COAP轮询选择出的HISTM Server设备,并获取它们的能力信息。
在一种可选的情况中,当HISTM Client设备收到具有希望调用的AI功能的一个HISTM Server设备的能力信息之后,HISTM Client设备停止获取其他HISTM Server设备的能力信息;在另一种可能的情况中,HISTM Client设备获取所有具有希望调用的AI功能的HISTM Server设备的能力信息,并根据预设规则选择能力更佳的HISTM Server设备。
具体的,HISTM Client设备可以通过COAP向HISTM Server设备发送第一命令CMD1,该CMD1包括HISTM Server设备的设备名、IP地址、端口号和信息获取命令,该信息获取命令用于指示获取HISTM Server设备的能力信息。
实际应用中,该CMD1的具体形式可以如下所示:
Send:coap://192.168.1.155:50614/CameraVideo0?ServiceInfo(value=Hi_STM_Test:11)
其中,192.168.1.155是某HISTM Server设备的IP地址,50614是该HISTM Server设备的端口号,CameraVideo0是该HISTM Server设备的设备名,ServiceInfo是信息获取命令,Hi_STM_Test:11是命令参数以及长度。
304、HISTM Server设备向HISTM Client设备回复能力信息;
HISTM Server设备收到CMD1之后,获取自身的能力信息,并通过第一回复报文Reply1将能力信息反馈给HISTM Client设备。
本实施例中,该Reply1报文格式可以如下所示:
“DevServiceType”:“Server设备名”,
“ServiceNum”:当前设备支持的可调用能力数量,
“能力1信息”:{“Name”:“能力名1”,“transport”:传输方式,“output-len-bytes”:输出数据长度},
“能力2信息”:{“Name”:“能力名2”,“transport”:传输方式,“output-len-bytes”:输出数据长度},
…
“能力N信息”:{“Name”:“能力名N”,“transport”:传输方式,“output-len-bytes”:输出数据长度}
其中,可调用能力数量用以表示HISTM Server设备所能支持的能力的数量。
能力名用以表示HISTM Server设备支持的AI功能的名称,例如人脸识别或骨骼检测等。
传输方式用以表示该Reply1报文通过何种传输方式发送,或者HISTM Client设备可以通过何种传输方式来调用该能力,或者用来表示该能力被调用后,HISTM Server设备通过何种传输方式来回传结果数据,具体使用哪种情况取决于实际应用环境的需求,此处不做限定。
输出数据长度用以表示该能力被调用后,HISTM Server设备回传的结果数据的长度。
本实施例中,上述能力信息可以通过一种轻量级的数据交换格式,如基于c语言的(c java script object notation,CJSON),进行存储,可以理解的是,也可以以其他的格式存储,具体此处不做限定。
305、HISTM Client设备根据能力信息确定符合要求的第一HISTM Server设备;
HISTM Client设备接收到各HISTM Client设备发送的Reply1报文后,可以根据Reply1报文中的能力信息确定出符合要求的第一HISTM Server设备,该第一HISTM Server设备的能力信息中包括目标AI功能,该目标AI功能为HISTM Client设备希望远程调用的AI功能。
需要说明的是,如果HISTM Client设备根据当前获取到的Reply1报文中的能力信息没有找到符合要求的HISTM Server设备,则HISTM Client设备会继续等待下一个HISTM Server设备。
306、HISTM Client设备向第一HISTM Server设备发送连接建立请求;
HISTM Client设备确定第一HISTM Server设备后,可以通过COAP向第一HISTM Server设备发送第二命令CMD2以请求建立连接。
该CMD2包括第一HISTM Server设备的设备名、IP地址、端口号、连接建立命令和负载变量,其中,负载变量包括数据通道类型,第一HISTM Server设备的IP地址和数据通道端口。
实际应用中,该CMD2的具体形式可以如下所示:
Send:coap://192.168.1.155:50614/CameraVideo0?.sys.mediaservice.setup(value={“p”:2,“ep”:{“addr”:“192.168.1.155”,“port”:6666}})
其中,192.168.1.155是第一HISTM Server设备的IP地址,50614是第一HISTM Server设备的端口号,应当理解,HISTM Client设备通过该端口号指示的端口向第一HISTM Server设备发送命令,例如上述连接建立请求等,CameraVideo0是第一HISTM Server设备的设备名,连接建立命令为sys.mediaservice.setup,数据通道类型为p,数据通道的端口为6666。
需要说明的是,该数据通道的端口一般为HISTM Client设备向第一HISTM Server设备发送数据的端口,而第一HISTM Server设备向HISTM Client设备发送数据的端口可以根据负载变量中包括的端口确认,如当HISTM Client设备向第一HISTM Server设备发送数据的端口为6666时,可以配置第一HISTM Server设备向HISTM Client设备发送数据的端口为6666加1,即6667,可以理解的是,上述仅为一种确定端口的方式,实际应用中还可以有其他方式,具体此处不做限定。
307、第一HISTM Server设备创建数据通道;
第一HISTM Server设备接收到HISTM Client设备发送的CMD2之后,会向HISTM Client设备发送第二回复报文Reply2,并创建接收数据通道和发送数据通道。
其中,发送数据通道用于向HISTM Client设备回传结果数据,接收数据通道用于从HISTM Client设备接收数据,如固件升级数据等。
数据通道建立后,HISTM Client设备和第一HISTM Server设备实现双向数据互通。
需要说明的是,第一HISTM Server设备可以根据实际需求选择建立接收数据通道和发送数据通道,如果不需要进行固件升级等操作或者AI功能待处理的源数据均来自于第一HISTM Server设备的本端等无需接收外来数据的场景,则可以不建立接收数据通道,具体此处不做限定。
308、HISTM Client设备向第一HISTM Server设备发送调用指令;
本实施例中,HISTM Client设备可以通过COAP向第一HISTM Server设备发送第三命令CMD3,以请求调用第一HISTM Server设备的目标AI功能。
该CMD3可以包括调用者ID、能力调用命令、调用信息报文,其中,调用信息报文包括被调用的能力名、数据源和传输方式。
按照数据源的不同,该CMD3可以有多种不同的形式:
1、数据源为第一HISTM Server设备:
本实施例中,数据源可以为第一HISTM Server设备,即表示第一HISTM Server设备的AI功能待处理的数据来自于第一HISTM Server设备本端,或者说AI功能使用第一HISTM Server设备中的数据进行处理,例如基于第一HISTM Server设备中的AI摄像机采集的视频流信息。
此时,该CMD3的具体形式可以如下所示:
Send:coap://192.168.1.155:50614/CameraVideo0?command(value={“ClientID”:1,“cmd”:“subscribe”,“subscribe”:{调用信息报文}})
其中,调用信息报文的具体形式可以如下所示:
{“Service”:“能力名”,“DataSource”:0,“TrasType”:2}
其中,192.168.1.155是第一HISTM Server设备的IP地址,50614是第一HISTM Server设备的端口号,CameraVideo0是第一HISTM Server设备的设备名,ClientID是调用者标识,“cmd”:“subscribe”,“subscribe”是能力调用命令。
需要说明的是,ClientID可以有多种表现形式,如果是设备级别的调用,ClientID可以是HISTM Client设备的标识,如果是业务级别的调用,ClientID可以是HISTM Client设备的某个业务的标识,具体此处不做限定。
“Service”是被调用的能力名,该能力名必须与第一HISTM Server设备提供的能力名一致。
“DataSource”是数据源,本实施例中,数据源为第一HISTM Server设备。
“TrasType”是传输方式,用以表示该调用信息报文通过何种传输方式发送,或者用来表示该能力被调用后,第一HISTM Server设备通过何种传输方式来回传结果数据,具体使用哪种情况取决于实际应用环境的需求,此处不做限定。
2、数据源为HISTM Client设备:
本实施例中,数据源可以为HISTM Client设备,即表示第一HISTM Server设备使用HISTM Client设备传送的数据进行处理。
此时,该CMD3的具体形式可以如下所示:
Send:coap://192.168.1.155:50614/CameraVideo0?command(value={“ClientID”:1, “cmd”:“subscribe”,“subscribe”:{调用信息报文}})
其中,调用信息报文的具体形式可以如下所示:
{“Service”:“能力名”,“DataSource”:1,“TrasType”:2}
此时CMD3中的各参数与前述描述的内容基本类似,类似的部分不再赘述,区别主要在于“DataSource”,本实施例中,数据源为HISTM Client设备。
需要说明的是,“DataSource”的具体取值在实际应用中不做限定,只要能够区分不同的数据源既可。
309、第一HISTM Server设备根据调用指令进行处理;
第一HISTM Server设备接收到调用指令后,可以根据调用指令进行相应的处理,例如运行目标AI功能。
需要说明的是,如果CMD3中指示数据源为第一HISTM Server设备,则第一HISTM Server设备使用本地的数据进行处理。
如果CMD3中指示数据源为HISTM Client设备,则第一HISTM Server设备首先需要通过已建立的接收数据通道从HISTM Client设备接收待处理的数据,当收到HISTM Client设备发送的数据发送完成命令时,则第一HISTM Server设备可以使用已经接收到的待处理的数据进行处理。
310、第一HISTM Server设备向HISTM Client设备发送结果数据。
第一HISTM Server设备根据调用指令进行相应的处理后,可以向HISTM Client设备发送结果数据,该结果数据包括第一HISTM Server设备根据CMD3运行目标AI功能后生成的数据。
本实施例中,结果数据的具体形式可以如图4所示。
其中,结果数据可分为报文头和负载数据两部分。

需要说明的是,上述实施例均是以SSDP和COAP为例进行说明的,由于SSDP和COAP都属于轻量级互联协议,所以可以在资源受限的物联网设备中运行,从而提升了本申请实施例的适应范围。
可以理解的是,本申请实施例并不一定需要使用SSDP和COAP,也可以使用HISTM中的其他协议实现,具体此处不做限定。
本申请实施例中,HISTM Client设备和HISTM Server设备既可以是同一个平台的设备(例如都属于Android平台或Linux平台),也可以是跨平台的设备(例如其中之一是Android平台,另一个是Linux平台),下面对跨平台的情况进行介绍:
请参阅图8,整体互联设备分为HISTM Client设备(Android device)和HISTM Server设备(Linux device)。
此互联架构可用于Android TV设备或机顶盒设备远程调用AI Camera的AI能力(人脸检测、人脸识别等),实现AI业务拓展的产品形态。
在该互联架构中,HISTM Client设备可以分为三层:应用程序(application,APP)层、HISTM服务层(HISTM Service层)、HISTM协议层。各个APP为独立的进程,HISTM Service和HISTM协议属于同一进程。APP进程通过Android C/S Binder与HISTM Service进程通信,实现对底层HISTM协议的调用。HISTM Service层属于中间层,向协议层传递上层APP的调用信息,它支持多实例访问,每一个APP进程在HISTM Service内部都有唯一的HISTM Server对应。
最底层为HISTM协议层,它包含了COAP、SSDP等协议,同时支持多实例调用,可支撑多个HISTM Server同时调用。
在该互联架构中,HISTM Server设备可以分为两层:APP层和HISTM协议层。APP层和HISTM协议属于同一进程。
APP运行后,读取本地存储的能力信息配置文件,并将能力信息注册到HISTM协议中,等待HISTM Client设备的能力调用。
基于上面的架构,下面对跨平台下HISTM Client设备和HISTM Server设备之间的数据交互过程进行描述:
以HISTM Client设备的AI人脸检测APP1、骨骼识别APP2为例,系统启动后,HISTMService在后台运行,APP1和APP2通过HISTM JNI、Binder模块查询HISTM协议层的SSDP设备列表,然后通过命令通道轮询各个HISTM Server设备支持的设备能力。
HISTM Server设备收到查询信息后,将本端的能力信息返回给HISTM Client设备HISTM协议层,然后通过Binder Notify机制将能力信息传回APP。
如果HISTM Server设备传回的能力信息中包括“人脸检测”、“骨骼识别”能力,APP1、APP2分别向HISTM Server设备发送远程能力调用命令,调用人脸检测能力和骨骼识别能力。
HISTM Server设备收到能力调用命令后,根据能力名,开启能力信息中对应能力的处理,并将结果数据通过数据通道发送回HISTM Client设备。
HISTM Client设备收到数据后,通过共享内存将数据回传给APP层,APP将实际的数据用于具体业务,完成整个流程。
本实施例中的信息传输方法在跨平台的场景下也能实现HISTM Client设备调用HISTMServer设备的能力,所以提升了适应范围。
需要说明的是,HISTM除了能够应用于上述场景之外,还可以广泛应用于智慧家庭领域,下面对HISTM在智慧家庭领域的应用进行介绍:
请参阅图9,普通扫地机器人(HISTM Client设备)通过WiFi与家庭智能计算中心(HISTM Server设备)建立网络连接。
普通扫地机器人的HISTM模块运行后,远程调用家庭智能计算中心的扫地路线计算能力,将实时获取的扫地路线信息回传给扫地控制应用,实现对扫地路线的智能控制。
