具体实施方式
为了使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
另外，本公开实施例中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以下，对本公开实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)服务器(server)，是提供计算服务的设备，具有处理能力强、稳定性、可靠性、安全性、可扩展性、以及可管理性好等特点。服务器主要包括处理器、硬盘、内存、系统总线等。服务器作为网络的节点，可以存储和处理网络上的数据和信息。根据服务器提供的服务类型不同，可以将其划分为文件服务器、数据库服务器、应用程序服务器或网络(web)服务器等，或根据服务器的用途不同，可以将其划分为国内服务器、云服务器或免备案服务器等。
本公开实施例所涉及的服务器，可以包括APP对应的服务器，可以理解为，该APP的功能通过该服务器来支撑。
(2)客户端(client)，是与服务器相对应，为客户提供本地服务的程序或设备。客户端可以只在本地运行，或者也可以通过网络与服务器配合运行。客户端可以是终端设备本身，终端设备例如为手机、个人计算机(personal computer，PC)、平板电脑或智能手表等；或者，客户端也可以是安装在终端设备上的第三方应用，例如，APP或小程序等；或者，客户端也可以是终端设 备可以访问的网页等。
请参考图1，为本公开实施例的一种应用场景的示意图。图1包括服务器、客户端和第一设备。其中，服务器和客户端之间可以通信，第一设备和服务器之间可以通信，而第一设备和客户端需要通过服务器来实现通信，相当于，第一设备和客户端之间传输的消息，需要通过服务器来转发。
图1中以两个客户端为例，分别为客户端1和客户端2。在实际应用中，客户端的数量不限于此。当然在实际应用中，被控设备的数量也不限于只有第一设备，可能还有多个设备。第一设备例如为家电设备，例如电视机、电冰箱、空调或电饭煲等。或者，被控设备也不限于只有家电设备，其他的一些设备也能够通过客户端进行控制，例如工业设备或其他类型的设备等。
另外，在被控设备有多个时，所使用的客户端可能是同一个，例如有些客户端可以实现对多种设备的控制，或者，也可能不同的设备对应不同的客户端。具体的不做限制。
下面结合说明书附图对本公开实施例作进一步详细描述。
本公开实施例提供一种控制设备的方法，请参考图2，为该方法的流程。
S21、客户端向服务器发送控制信息，服务器接收来自客户端的控制信息。
用户如果需要控制第一设备，可以通过客户端进行操作。例如，用户位于一个房间，需要对另一个房间内的设备进行控制，则可以采用本公开实施例的控制方式，例如，用户在卧室时，需要提前打开客厅的空调，则用户可以通过客户端控制客厅的空调开启，使得用户无需走到另一个房间才能进行控制；或者，用户不在家中，但需要对家中的家电设备进行控制，例如用户在到家前，需要烧水壶提前烧好水，则用户可以在到家前通过客户端控制烧水壶开启烧水功能，或者通过客户端预约烧水壶的开启时间；或者，用户不在办公室，但需要对办公室中的设备进行控制，例如用户在到达公司之前，通过客户端打开办公室的窗帘，等等。如上的这些场景，用户都可以使用本公开实施例所提供的方法来对相应的设备进行控制。
以客户端是安装在用户手机中的APP为例，介绍用户对第一设备进行控制的过程。例如，用户调用手机中的该APP，手机的显示屏可以显示该APP的界面。用户在该APP的界面中点击相应的功能按键(可能是软件按键或硬件按键)，则该APP可以生成对应的控制信息，该控制信息就可以用于控制第一设备执行第一操作。
例如，用户要控制的第一设备是空调，用户在APP中选择的功能是“开启”功能，则用户点击该功能对应的功能按键后，该APP可以生成用于控制空调执行开启操作的控制信息。再例如，用户要控制的第一设备是洗衣机，用户在APP中选择的功能是“快速洗涤”功能，则用户点击该功能对应的功能按键后，该APP可以生成用于控制洗衣机进入快速洗涤模式的操作的控制信息。
在生成控制信息后，客户端可以将控制信息发送给服务器，则服务器就可以接收来自客户端的该控制信息。
S22、服务器确定第一设备是否处于被控制状态。如果第一设备处于被控制状态，执行S23，或者，如果第一设备未处于被控制状态，执行S24。
服务器接收来自客户端的控制信息之后，根据控制信息可以确定需要被控制的第一设备，从而确定第一设备是否处于被控制状态。例如，控制信息可以携带第一设备的标识，服务器根据第一设备的标识就可以确定第一设备。第一设备的标识例如包括第一设备的身份号(ID)、第一设备的名称或第一设备的编号中的一种或多种。例如，第一设备的标识包括第一设备的ID，或者，第一设备的标识包括第一设备的名称和第一设备的编号，或者，第一设备的标识包括第一设备的ID、第一设备的名称和第一设备的编号，等等。
例如，当一个设备首次成功连接客户端后，用户可以通过客户端为该设备设置名称，或者，当一个设备首次成功连接服务器后，服务器可以为该设备分配ID或编号。设备连接客户端的方式可以是有线或者无线的方式，无线方式例如包括无线局域网或蓝牙等方式。以客户端是安装在用户手机中的APP为 例，例如用户家中新添置了一台空调，该空调通电后，通过连接家中的无线局域网与该APP进行连接，用户即可通过APP查看或控制该空调。
服务器要确定第一设备是否处于被控制状态，可能有不同的确定方式。下面进行介绍。
1、服务器确定第一设备是否处于被控制状态的第一种方式。
如果有客户端向服务器发送用于控制第一设备的控制信息，例如为控制信息1，且服务器将控制信息1转发给了第一设备，则服务器可以记录该事件。如果后续第一设备执行该控制信息1所指示的操作完毕，则第一设备可以向服务器发送消息，该消息用于指示第一设备已受控完毕，或指示第一设备未处于被控制状态，或指示第一设备已对来自客户端的控制信息1响应完毕。服务器接收该消息后，就可以确定第一设备不再处于被控制状态，其他客户端可以对第一设备进行控制。则服务器可以删除所记录的事件。
或者，第一设备可能未向服务器发送消息，如果在服务器将控制信息1发送给第一设备后的第一时长到达时，服务器仍未接收来自第一设备的消息，则服务器也可以确定第一设备已受控完毕，也就是确定第一设备不再处于被控制状态。则服务器也可以删除所记录的事件。
而在第一设备未向服务器发送消息之前，或者在第一时长未到达之前，服务器都确定第一设备处于被控制状态，可以继续维持所记录的事件。
则服务器通过查询第一设备是否对应有所记录的事件，就可以确定第一设备是否处于被控制状态。
2、服务器确定第一设备是否处于被控制状态的第二种方式。
如果有客户端向服务器发送用于控制第一设备的控制信息，例如为控制信息1，且服务器将控制信息1转发给了第一设备，则服务器可以为第一设备添加互斥锁，例如，服务器可以为本地存储的第一设备的标识添加互斥锁。互斥锁可以有两种状态，“上锁(lock)”和“解锁(unlock)”。例如，为第一设备的标识添加互斥锁，可以理解为，将第一设备的标识对应的互斥锁的状态设置 为“上锁”。互斥锁是一种避免同时访问共享资源的方式。在本公开实施例中，服务器通过添加互斥锁，可以避免多个客户端同时控制同一个设备。
如果后续第一设备执行该控制信息1所指示的操作完毕，则第一设备可以向服务器发送消息，该消息用于指示第一设备已受控完毕，或指示第一设备未处于被控制状态，或指示第一设备已对来自客户端的控制信息1响应完毕。服务器接收该消息后，就可以确定第一设备不再处于被控制状态，其他客户端可以对第一设备进行控制。则服务器可以为第一设备的标识解除互斥锁。例如，为第一设备的标识解除互斥锁，可以理解为，将第一设备的标识对应的互斥锁的状态设置为“解锁”。
或者，第一设备可能未向服务器发送消息，如果在服务器将控制信息1发送给第一设备后的第一时长到达时，服务器仍未接收来自第一设备的消息，则服务器也可以确定第一设备已受控完毕，也就是确定第一设备不再处于被控制状态。则服务器也可以为第一设备的标识解除互斥锁。
以第一设备是电视机，客户端是APP为例，介绍服务器通过第二种方式确定第一设备是否处于被控制状态的过程。例如，用户对该APP进行操作，点击了该APP提供的用于开启电视机的按键，则该APP生成对应的控制信息a，该APP将控制信息a发送给服务器，控制信息a用于令电视机执行开启电视机的操作。该APP向服务器发送控制信息a，控制信息a携带要控制的电视机的ID。服务器接收来自APP的控制信息a，并根据控制信息a中的电视机的ID，确定APP需要控制的电视机。服务器检查该电视机的标识对应的互斥锁的状态，如果互斥锁的当前状态是“上锁”，则APP无权对该电视机进行控制，如果互斥锁的当前状态是“解锁”，则服务器将控制信息a转发给该电视机，则服务器为该电视机添加互斥锁，即，服务器将该电视机的标识对应的互斥锁的状态设置为“上锁”。如果该电视机执行完毕开启电视机的操作，则该电视机向服务器发送消息，该消息指示该电视机已受控完毕，或指示该电视机未处于被控制状态，或指示该电视机已对来自APP的控制信息a响应完毕。服务器 接收到该消息后，就可以确定该电视机不再处于被控制状态，其他客户端可以对该电视机进行控制。则服务器为该电视机解除互斥锁，即，该电视机对应的互斥锁的状态设置为“解锁”。
或者，该电视机未向服务器发送消息，例如第一时长为100秒。则，如果在服务器将控制信息a发送给电视机后的100秒到达时，服务器仍未接收来自该电视机的消息，则服务器确定该电视机已受控完毕，或该电视机不再处于被控制状态。则服务器为该电视机解除互斥锁，即，该电视机对应的互斥锁的状态设置为“解锁”。
而在第一设备未向服务器发送消息之前，或者在第一时长未到达之前，第一设备的标识对应的互斥锁的状态都是“上锁”，表明第一设备处于被控制状态。
则服务器通过查询第一设备的标识对应的互斥锁的状态就可以确定第一设备是否处于被控制状态。
3、服务器确定第一设备是否处于被控制状态的第三种方式。
如果有客户端向服务器发送用于控制第一设备的控制信息，例如为控制信息1，且服务器将控制信息1转发给了第一设备，则服务器可以开启定时器，该定时器的定时时长例如为第一时长。该定时器的定时时长可以由服务器设置，或者由用户通过客户端设置，或者也可以通过协议或行业标准规定。
在该定时器超时之前，如果第一设备执行该控制信息1所指示的操作完毕，则第一设备可以向服务器发送消息，该消息用于指示第一设备已受控完毕，或指示第一设备未处于被控制状态，或指示第一设备已对来自客户端的控制信息1响应完毕。服务器接收该消息后，就可以确定第一设备不再处于被控制状态，其他客户端可以对第一设备进行控制。在这种情况下，服务器可以关闭该定时器。
或者，如果在该定时器超时时，服务器仍未接收来自第一设备的消息，则服务器也可以确定第一设备已受控完毕，也就是确定第一设备不再处于被控制 状态。
而在第一设备未向服务器发送消息之前，或者在该定时器超时之前，该定时器是处于运行状态，服务器都确定第一设备处于被控制状态。
则服务器通过查询该定时器是否处于运行状态，就可以确定第一设备是否处于被控制状态。
如上的三种确定方式，都是由服务器自行确定即可，无需询问第一设备，可以减轻第一设备的负担，也减少设备之间的信息交互，节省信令开销。
4、服务器确定第一设备是否处于被控制状态的第四种方式。
服务器可以向第一设备询问第一设备是否处于被控制状态。例如，有客户端向服务器发送了用于控制第一设备的控制信息，则服务器可以向第一设备发送消息，例如称为第一消息，第一消息用于查询第一设备是否处于被控制状态。
第一设备接收第一消息后可以向服务器发送第二消息，第二消息用于指示第一设备处于被控制状态或未处于被控制状态。则服务器根据第二消息就可以确定第一设备是否处于被控制状态。
这种确定方式较为简单，服务器无需维护过多的状态，只需直接向第一设备查询即可。
服务器可以通过如上的任意一种方式来确定第一设备是否处于被控制状态。或者，关于服务器确定第一设备是否处于被控制状态，还可能有其它的确定方式，本公开实施例不做限制。
S23、当第一设备未处于被控制状态时，服务器将控制信息转发给第一设备，第一设备接收来自服务器的控制信息。
如果在S22中服务器确定第一设备未处于被控制状态，则服务器可以将所述的控制信息转发给第一设备，第一设备可以根据该控制信息执行第一操作。
例如，用户要控制的第一设备是空调，客户端是安装在用户手机中的APP。用户在APP中选择的功能是空调的“开启”功能，用户点击该功能对应的功能按键后，APP向服务器发送控制空调执行开启操作的控制信息b，控制信息 b携带要控制的空调的编号(例如为空调的序列号)。服务器根据控制信息b中的空调的编号，确定用户需要控制的空调。例如服务器采用如前所述的第二种方式来确定空调是否处于被控制状态，服务器确定该空调的标识对应的互斥锁的状态为“解锁”，也就是说，该空调未处于被控制状态，则服务器将控制信息b转发给该空调。该空调接收来自服务器的控制信息b后，可以根据控制信息b，执行开启该空调的操作。而服务器在将控制信息b转发给该空调时，会将该空调的标识对应的互斥锁的状态设置为“上锁”。
一般来说，第一设备执行一个控制信息结束后，会向服务器发送信息，以指示第一设备已执行控制信息完毕，或者指示第一设备未处于被控制状态。因此，服务器将控制信息转发给第一设备后，可以等待接收来自第一设备的信息，从而可以根据所接收的信息确定第一设备已受控完毕，也就是确定第一设备不再处于被控制状态。如果服务器在第一时长结束前接收了来自第一设备的信息，就可以确定第一设备不再处于被控制状态，其他客户端可以对第一设备进行控制。例如服务器采用的是如上所述的第二种方式确定第一设备是否处于被控制状态，则服务器可以将该空调的标识对应的互斥锁的状态设置为“解锁”。
或者，服务器等待了第一时长，在第一时长的结束时刻到达时仍然未接收来自第一设备的指示信息，则服务器也可以确定第一设备已受控完毕，也就是确定第一设备不再处于被控制状态。例如服务器采用的是如上所述的第二种方式确定第一设备是否处于被控制状态，则服务器可以将该空调的标识对应的互斥锁的状态设置为“解锁”。
S24、当第一设备处于被控制状态时，服务器向客户端发送第一指示信息。
如果在S22中服务器确定第一设备处于被控制状态，则第一设备不能再接受其他客户端的控制。因此，服务器不将控制信息发送给第一设备，这样可以保证第一设备在受控时不再接受其他客户端的控制，避免第一设备出现误响应或故障等。
而服务器不向第一设备发送该控制信息，也就表明不能对所述的客户端发 送的控制信息进行响应。作为对该客户端的回复，服务器可以向该客户端发送第一指示信息，第一指示信息可以指示第一设备处于被控制状态，或指示当前无法控制第一设备，或指示第一设备正在被其他客户端所控制。该客户端接收第一指示信息后，就可以确定当前无法控制第一设备。
之后，第一设备被控制完毕后，可能向服务器发送第二指示信息，即表示第一设备不再处于被控制状态，其他客户端可以对第一设备进行控制。则服务器可以再向客户端发送第三指示信息，即，指示第一设备已对来自其他客户端的控制信息响应完毕，或指示第一设备未处于被控制状态。
或者，可能服务器等待第一时长后，即第一时长的结束时刻到达时，仍未收到来自第一设备的第二指示信息，则服务器确定第一设备被控制完毕。服务器可以再向客户端发送第三指示信息，即，指示第一设备已对来自其他客户端的控制信息响应完毕，或指示第一设备未处于所述被控制状态。
例如，用户要控制的第一设备是空调，客户端是安装在用户手机中的APP。用户在APP中选择的功能是空调的“关闭”功能。用户点击该功能对应的功能按键后，APP生成用于控制空调关闭的控制信息c，APP将向服务器发送控制信息c，控制信息c携带要控制的空调的ID。服务器根据控制信息c中的空调的ID，确定用户需要控制空调。例如服务器采用如前所述的第二种方式来确定空调是否处于被控制状态，服务器确定该空调的标识对应的互斥锁的状态为“上锁”，也就是说，该空调可能正在执行来自某个客户端的“上下扫风”操作的控制信息d，不能再接受其他客户端的控制。此时，服务器不会向该空调转发控制信息c，而是向APP发送空调处于被控制状态的指示信息，或当前无法控制空调的指示信息。
当空调执行完成控制信息d之后，空调向服务器发送控制指令d执行完毕的信息，即，表示空调不再处于被控制状态，其他客户端可以对空调进行控制。则服务器向APP发送空调已对来自其他客户端的控制信息响应完毕的信息，也就是空调未处于被控制状态的信息。服务器可以将该空调的标识对应的互斥 锁的状态设置为“解锁”。
或者，服务器设置为等待100秒，如果在100秒内，服务器未收到来自空调的控制指令d执行完毕的信息，则在100秒结束时刻，服务器确定空调已受控完毕，也就是确定空调未处于被控制状态。则服务器向APP发送空调已对来自其他客户端的控制信息响应完毕的信息，也就是空调未处于被控制状态的信息。服务器可以将该空调的标识对应的互斥锁的状态设置为“解锁”。
此时，APP接收来自服务器的空调未处于被控制状态的信息，由使用APP的用户决定是否再向空调发送控制指令c。如果用户通过APP再一次选择了空调的“关闭”功能，用户点击该功能对应的功能按键后，APP向服务器发送控制信息c。服务器根据控制信息c中的空调的ID，确定用户需要控制的空调。例如，服务器确定该空调的标识对应的互斥锁的状态为“解锁”，也就是说，空调未处于被控制状态，则服务器将控制信息c转发给该空调。空调接收来自服务器的控制信息c后，可以根据控制信息c，执行开启该空调的操作。而服务器在将控制信息c转发给该空调时，会将该空调的标识对应的互斥锁的状态设置为“上锁”。如果用户不再通过APP控制该空调，则APP接收来自服务器的空调未处于被控制状态的信息后，不做进一步响应。
在本公开实施例中，在客户端要对第一设备进行控制时，如果服务器确定第一设备未处于被控制状态，则服务器可以将控制信息转发给第一设备，以使得客户端完成对第一设备的控制。例如，服务器确定第一设备处于被控制状态，则服务器可以不向第一设备转发控制信息，相当于，如果第一设备正在被其他客户端所控制，则该客户端就无法控制第一设备。通过这种方式，尽量避免一个设备同时被多个客户端控制的情况出现，避免了冲突，可以确保设备的实际工作状态和客户端所知晓的该设备的工作状态一致，也可以减少设备出现无法响应或故障等事件的概率。
基于同一发明构思，本公开实施例提供一种服务器，该服务器能够实现前述的控制设备的方法对应的功能。该服务器可以是硬件结构、软件模块、或硬 件结构加软件模块。该服务器可以由芯片系统实现，芯片系统可以由芯片构成，也可以包含芯片和其他分立器件。请继续参考图3，该服务器包括发送模块301、接收模块302和处理模块303。其中：
