图4为本申请实施例提供的服务器的一种结构示意性框图。
具体实施方式
下面将结合本说明书实施例中的附图,对本说明书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说明书一部分实施例,而不是全部的实施例。基于本说明书中的实施例,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,都属于本说明书保护的范围。
附图中所示的流程图仅是示例说明,不是必须包括所有的内容和操作/步骤,也不是必须按所描述的顺序执行。例如,有的操作/步骤还可以分解、组合或部分合并,因此实际执行的顺序有可能根据实际情况改变。
下面结合附图,对本说明书的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
本申请实施例中的设备控制方法,可以应用于如图1所示的应用场景。在该场景中,远程管理平台10可以连接多个设备20,其中,各个设备20支持的通信协议不尽相同,即各个设备20支持的协议类型不尽相同,例如,有些设备20支持MQTT协议,而有些设备20支持TR069协议,还有一些设备20支持OMADM(Open Mobile Alliance Device Management,开放行动联盟设备管理)协议等。
在一些实施方式中,远程管理平台10可以部署于服务器,管理者可以通过浏览器或内嵌有浏览器内核的应用等方式访问远程管理平台10,进而实现对设备20的远程操作,例如,管理者可以通过计算机终端上的浏览器访问远程管理平台10,进而在浏览器上远程操作设备20。其中,管理者在访问远程管理平台10时,可以通过登陆账号的方式以确定管理者的管理权限。在一些实施方式中,设备20可以是具有网络访问能力的有线设备、无线设备等,例如设备20可以是智能水表、智能电表等。
在一实施例中,提供了一种设备控制方法,如图2所示,该方法可以应用于部署在服务器上的远程管理平台,该方法包括但不限于步骤S210至S220。
步骤S210,当接收到用于控制目标设备的控制指令,根据目标设备的设备标识以及控制指令,确定对应目标设备的目标协议模型。
步骤S220,将目标协议模型中对应该控制指令的第一控制参数下发给目标设备,使目标设备执行对应控制指令的操作。
其中,远程管理平台接收到控制指令可以是接收到由设备或终端向远程管理平台发送的控制指令。在一些实施方式中,远程管理平台接收到控制指令可以包括但不限于如下方式:
(1)远程管理平台接收到由终端发送的控制指令,例如,当管理者需要智能水表上报用水量,管理者可以通过终端访问远程管理平台并向平台下发对应智能水表的控制指令,如此远程管理平台即可接收到控制指令。
(2)远程管理平台接收到由第一设备发送的控制指令,例如,第一设备为电流传感器,用于检测第二设备的工作电流,基于此,当电流传感器检测到第二设备的工作电流发生异常时,电流传感器向远程管理平台发送关闭第二设备的控制指令,如此远程管理平台即可接收到控制指令。
设备标识指的是可以代表目标设备的信息,简单理解就是设备标识为目标设备的身份 信息,例如设备标识可以包括IMEI(International Mobile Equipment Identity,国际移动设备识别码)、SN码(Serial Number、产品序列号)、IP地址等等。
需要说明的是,在服务器上可以预先建立多个协议模型,每个协议模型均根据一种通信协议预先建立,即一个协议模型对应一种通信协议。另外,每个协议模型中均记录有控制参数,且一个协议模型中记录的控制参数对应一种控制指令,例如第一协议模型中记录的控制参数对应控制指令“监控数据流量”,而第二协议模型中记录的控制参数对应控制指令“打开WiFi开关”。在一些实施方式中,控制参数可以是一个或多个协议节点,也可以是一个或多个协议参数。可以理解,目标协议模型为根据目标设备所支持的通信协议而预先建立的模型,且目标协议模型中的第一控制参数对应步骤S210中所述的控制指令。
基于此,当远程管理平台接收到控制指令时,可以根据目标设备的设备标识以及控制指令,确定对应目标设备的目标协议模型,可以理解,目标协议模型对应的通信协议即为目标设备所支持的通信协议。在确定目标协议模型之后,由于目标协议模型中的第一控制参数对应远程管理平台接收到的控制指令,因此将目标协议模型中的第一控制参数下发给目标设备,目标设备在接收到第一控制参数后即可执行对应该控制指令的操作。
示例性的,服务器上已预先建立有两个协议模型,其中,第一协议模型对应MQTT协议,且第一协议模型中的第一控制参数包括一个或多个协议参数,例如,第一协议模型中包括:[{"gpsTime":1590374995000,"latitude":23.456789,"longitude":12.345678}],则第一协议模型中记录有三个协议参数,分别为gpsTime(代表gps时间)、latitude(代表经度)和longitude(代表纬度);第二协议模型对应TR181(Technical Report-181)协议,则第二协议模型中的第一控制参数包括一个或多个协议节点,例如,第二协议模型中包括:Device.WiFi.Radio.2.Enable,则第二协议模型中记录有Device、WiFi、Radio、2、Enable这些协议节点,另外,第二协议模型中的第一控制参数对应控制指令“打开WiFi开关”。基于此,当远程管理平台接收到用于控制目标设备的控制指令“打开WiFi开关”,可以根据SN码以及控制指令“打开WiFi开关”,确定目标协议模型为第二协议模型,从而将第二协议模型中对应该控制指令的第一控制参数下发给目标设备,以打开目标设备的WiFi开关。
在一实施例中,步骤S210包括但不限于步骤S211至S212。
步骤S211,根据目标设备的设备标识及预设的映射关系表,确定目标设备支持的通信协议。
步骤S212,根据目标设备支持的通信协议及控制指令,确定目标协议模型。
由前述可知服务器上可以预先建立有多个协议模型且每个协议模型对应一种通信协议,另外,每个协议模型都是根据被控设备建立的且被控设备通常支持一种通信协议,因此,在建立协议模型时,可以将一个或多个被控设备的设备标识与其支持的通信协议记录在映射关系表中。基于此,可以根据目标设备的设备标识,在映射关系表中找到该设备支持的通信协议,进而可以根据协议类型与控制指令确定目标协议模型。
在一实施例中,步骤S212包括但不限于步骤S213至S214。
步骤S213,根据目标设备支持的通信协议,在预设的多个协议模型中筛选出一个或多个相对应的协议模型。
步骤S214,根据控制指令,在一个或多个协议模型中确定对应该控制指令的协议模型 作为目标协议模型。
对于不同种类的设备,这些设备支持的通信协议可能是同一种通信协议,但是这些设备可能由于自身的硬件配置而具备不同的功能,例如,设备A、设备B与设备C支持的都是TR181协议,而设备A具备的功能为锁网功能,设备B具备的功能为设备绑定功能,设备C具备的功能为数据流量监控功能。基于此,根据设备A建立的协议模型A、根据设备B建立的协议模型B以及根据设备C建立的协议模型C,这三个协议模型虽然都对应同一种通信协议,比如都对应TR181协议,但是这三个协议模型中记录的控制参数是不一样的,比如协议模型A中记录的一个或多个控制参数是关于锁网的,协议模型B中记录的一个或多个控制参数是关于设备绑定的,协议模型C中记录的一个或多个控制参数是关于数据流量监控的,可以理解,每一协议模型均对应一种通信协议且对应一种控制指令。
基于此,可以先根据目标设备支持的通信协议筛选出一个或多个协议模型,这些协议模型都对应该类型的通信协议,接着根据控制指令在这些协议模型中确定对应该控制指令的协议模型作为目标协议模型,例如,该控制指令为打开WiFi开关,则根据这个控制指令即可确定目标协议模型,且目标协议模型中的第一控制参数对应于打开WiFi开关的控制指令。
示例性的,服务器上已预先建立有对应目标设备的目标协议模型,目标协议模型可以对应TR181协议,并且,在建立目标协议模型时已将目标设备的设备标识与目标设备支持的通信协议记录在映射关系表中。基于此,远程管理平台在接收到用于控制目标设备的控制指令时,可以根据目标设备的设备标识(比如SN码)在映射关系表中确定该目标设备所支持的通信协议为TR181协议,进而在服务器上找到一个或多个对应TR181协议的协议模型,接着根据这个控制指令在这些协议模型中确定目标协议模型,例如该控制指令为打开WiFi开关,则确定出的目标协议模型中的第一控制参数对应打开WiFi开关这个控制指令。
在一实施例中,如图3所示,在步骤S210之前,该方法包括但不限于步骤S110至S140。
步骤S110,接收目标设备上报的设备信息,并提取出该设备信息中预设的第二控制参数。
步骤S120,根据第二控制参数确定是否存在目标协议模型。
步骤S130,当确定不存在目标协议模型,向目标设备下发全参采集指令,以使目标设备上报预设的第三控制参数。
步骤S140,根据第三控制参数,建立目标协议模型。
在确定对应目标设备的目标协议模型之前,可以先确定是否存在目标协议模型,若存在则可以执行步骤S210,若不存在则需建立对应目标设备的目标协议模型。基于此,可以接收目标设备上报的设备信息,由于设备信息为目标设备根据目标设备支持的通信协议而生成的上报信息,即设备信息包括了对应该通信协议的第二控制参数,例如包括了通信协议规定的一些必要的协议节点或协议参数,因此可以在该设备信息中提取出第二控制参数,从而根据第二控制参数确定是否存在目标协议模型。
在一些实施方式中,步骤S120包括但不限于步骤S121。
步骤S121,将第二控制参数与预设的各个协议模型中记录的控制参数进行匹配,以确定是否存在目标协议模型。
由于各个协议模型中均记录有控制参数,因此可以将第二控制参数与预先建立的各个协议模型进行匹配,即将第二控制参数与协议模型中记录的控制参数进行匹配,例如判断协议模型中记录的控制参数是否包括了第二控制参数,若包括则表示能够匹配,即存在目标协议模型,否则不存在目标协议模型。
因此由前述可知,当确定不存在目标协议模型时,需要建立目标协议模型。基于此,由于设备信息中的第二控制参数可以包括部分协议节点或部分协议参数,比如主要包括通信协议规定的一些必要的协议节点或协议参数,因此可以向目标设备下发全参采集指令,以使目标设备上报预设的第三控制参数,在一些实施方式中,第三控制参数包括了全部协议节点或全部协议参数,比如包括了必要的协议节点或协议参数以及其他的协议节点或协议参数,可以理解,第三控制参数包括了第二控制参数。如此,可以根据第三控制参数建立目标协议模型,在一些实施方式中,可以将第三控制参数进行处理并记录到新建的协议模型中,以得到对应目标设备的协议模型。
在一实施例中,如图3所示,在步骤S120之后,该方法包括但不限于步骤S150。
步骤S150,当确定存在目标协议模型,根据第二控制参数更新目标协议模型。
当确定存在目标协议模型时,说明已经为目标设备建立了对应的协议模型,不必再建立目标协议模型。在一些实施方式中,可以根据第二控制参数更新目标协议模型,例如可以将第二控制参数中一个或多个协议节点或协议参数去替换目标协议模型中相同的协议节点或协议参数,和/或,将目标协议模型中一些不属于该模型的协议节点或协议参数删除。
综上可以理解,对于支持不同通信协议的设备,可以在服务器上建立相对应的协议模型,如此,在远程管理平台接收到用于控制目标设备的控制指令时,可以根据设备标识与控制指令确定目标协议模型,进而将目标协议模型中对应该控制指令的第一控制参数下发给目标设备,以使目标设备执行相应的操作,实现远程管理。例如,对于支持不同通信协议的设备A、设备B与设备C,可以在服务器上预先建立相对应的协议模型A、协议模型B与协议模型C,如此当远程管理平台接收到用于控制设备A的控制指令时,可以确定出协议模型A,进而将协议模型A中对应该控制指令的第一控制参数下发给设备A,以使设备A执行相应的操作,设备B与设备C也类似,此处不再赘述。本申请实施例一个远程管理平台即可管理支持不同通信协议的设备,因此不需要构建多个远程管理平台,极具便利性且降低了管理者的运维成本;此外,当管理者增设了新的设备,在服务器上建立对应的协议模型即可实现对该设备的远程管理,因此提高了管理者的用户体验。
