终端控制方法及装置Terminal control method and device 技术领域Technical field
本发明涉及通信技术领域，尤其涉及一种终端控制方法及装置。The present invention relates to the field of communications technologies, and in particular, to a terminal control method and apparatus.
背景技术Background technique
RTSP(Real Time Streaming Protocol，实时流媒体协议)，是由Real network和Netscape共同提出的如何有效地在IP网络上传输流媒体数据的应用层协议。RTSP提供一种可扩展的框架，使RTSP服务端能够提供可控制的，按需传输实时数据，比如音频和视频文件。例如，在视频监控领域中，摄像头作为RTSP服务端，监控终端作为RTSP客户端，通常采用RTSP作为实时监控数据的传输控制协议，摄像头能够向监控终端提供诸如暂停、快进以及快退等媒体流控制。RTSP (Real Time Streaming Protocol) is an application layer protocol proposed by Real Network and Netscape to effectively transmit streaming media data over an IP network. RTSP provides an extensible framework that enables RTSP servers to provide controlled, on-demand real-time data, such as audio and video files. For example, in the field of video surveillance, the camera acts as an RTSP server, and the monitoring terminal acts as an RTSP client. RTSP is usually used as a transmission control protocol for real-time monitoring data. The camera can provide media streams such as pause, fast forward, and fast rewind to the monitoring terminal. control.
然而，在采用RTSP作为实时监控数据的传输控制协议之外，若RTSP客户端需要对RTSP服务端进行除媒体流控制之外的其它控制，如调整摄像头的监控区域，则需要RTSP客户端和RTSP服务端建立控制指令专用的控制信道，甚至需要额外的专用服务器负责控制命令的转发，需要消耗较多的网络资源。However, in addition to the RTSP as the transmission control protocol for real-time monitoring data, if the RTSP client needs to perform other control than the media stream control on the RTSP server, such as adjusting the surveillance area of the camera, the RTSP client and RTSP are required. The server establishes a control channel dedicated to the control command, and even needs an additional dedicated server to control the forwarding of the command, which requires more network resources to be consumed.

需要说明的是，本实施例的主旨在于利用已经建立的RTSP连接，使得RTSP客户端能够直接向RTSP服务端发送控制请求，从而无需建立新的专用连接发送控制请求，也不需要借助额外的专用服务器转发控制请求，以降低实现媒体流之外的其他控制所造成网络消耗，并提升控制效率。It should be noted that the main purpose of this embodiment is to utilize the established RTSP connection, so that the RTSP client can directly send a control request to the RTSP server, so that it is not necessary to establish a new dedicated connection to send a control request, and no additional dedicated The server forwards the control request to reduce network consumption caused by other controls other than the media stream, and improve control efficiency.
参照图2，RTSP服务端和RTSP客户端位于NAT设备之后，通过NAT设备接入公网，云服务器部署在公网，便于RTSP客户端和RTSP服务端建立连接。以下以RTSP客户端和RTSP服务端均为一台进行说明，本领域技术人员可以理解的是，在具体实施时，可按实际需要设置多台RTSP客户端以及多台RTSP服务端。Referring to FIG. 2, the RTSP server and the RTSP client are located behind the NAT device, and are connected to the public network through the NAT device. The cloud server is deployed on the public network, facilitating the connection between the RTSP client and the RTSP server. The following is an explanation of both the RTSP client and the RTSP server. Those skilled in the art can understand that, in the specific implementation, multiple RTSP clients and multiple RTSP servers can be set according to actual needs.
本实施例中，当存在控制需求时，用户可基于RTSP客户端触发可控设备获取请求发送至公网的云服务器；云服务器在接收到RTSP客户端发送的可控设备获取请求时，由于RTSP客户端和RTSP服务端处于同一个NAT设备之后，直接将RTSP服务端的私网地址返回至RTSP客户端；RTSP客户端在接收到云服务器返回的RTSP服务端的私网地址之后，基于接收的私网地址向RTSP服务端发送OPTION请求，以开启RTSP连接的建立流程。In this embodiment, when there is a control requirement, the user may trigger the controllable device acquisition request to be sent to the cloud server of the public network based on the RTSP client; when the cloud server receives the controllable device acquisition request sent by the RTSP client, due to the RTSP After the client and the RTSP server are in the same NAT device, the private network address of the RTSP server is directly returned to the RTSP client. After receiving the private network address of the RTSP server returned by the cloud server, the RTSP client is based on the received private network. The address sends an OPTION request to the RTSP server to open the RTSP connection establishment process.
为实现基于RTSP连接进行除媒体流控制之外的其它控制，在本实施例中，在RTSP服务端预设有自定义的设备控制方法，以RTSP服务端为配备有电控云台的摄像头为例，该设备控制方法可以包括该电控云台支持的动作，如向左/右/上/下转动、水平巡航以及垂直巡航等，基于不同的动作分别设置对应的控制参数，如控制参数LEFT对应向左转动，控制参数HNAVIGATE对应水平巡航等，具体可按需设置。In order to implement other control than the media stream control based on the RTSP connection, in the embodiment, a custom device control method is pre-configured on the RTSP server, and the RTSP server is equipped with an electronically controlled camera. For example, the device control method may include actions supported by the electronically controlled pan/tilt, such as left/right/up/down rotation, horizontal cruise, and vertical cruise, etc., respectively, corresponding control parameters are set based on different actions, such as control parameter LEFT Corresponding to the left rotation, the control parameter HNAVIGATE corresponds to horizontal cruise, etc., which can be set as needed.
RTSP服务端在接收到RTSP客户端发送的OPTION请求时，向RTSP客户端返回OPTION响应，其中，RTSP服务端向RTSP客户端返回的OPTION响应包括预设的设备控制方法，以及支持的其它所有方法。例如，RTSP客户端向RTSP服务端发送的OPTION请求如下所示：The RTSP server returns an OPTION response to the RTSP client when receiving the OPTION request sent by the RTSP client, wherein the OPTION response returned by the RTSP server to the RTSP client includes a preset device control method, and all other supported methods. . For example, the OPTION request sent by the RTSP client to the RTSP server is as follows:
OPTIONS rtsp://192.168.1.3:5000/***RTSP/1.0 OPTIONS rtsp://192.168.1.3:5000/***RTSP/1.0
CSeq:1CSeq: 1
RTSP服务端向RTSP客户端返回的OPTION响应如下所示：The OPTION response returned by the RTSP server to the RTSP client is as follows:
RTSP/1.0 200 OKRTSP/1.0 200 OK
CSeq:1CSeq: 1
Public:OPTIONS，DESCRIBE，SETUP，PLAY，PTZ，TEARDOWNPublic:OPTIONS,DESCRIBE,SETUP,PLAY,PTZ,TEARDOWN
其中，PTZ(Pan/Tilt/Zoom，云台控制)为预设的设备控制方法。Among them, PTZ (Pan/Tilt/Zoom, PTZ control) is a preset device control method.
本实施例中，RTSP客户端在接收到RTSP服务端返回的OPTION响应时，依次向RTSP服务端发送DESCRIBE、SETUP以及PLAY等请求，RTSP服务端则依次响应DESCRIBE、SETUP以及PLAY等请求，建立RTSP连接。In this embodiment, when receiving the OPTION response returned by the RTSP server, the RTSP client sequentially sends requests such as DESCRIBE, SETUP, and PLAY to the RTSP server, and the RTSP server sequentially responds to requests such as DESCRIBE, SETUP, and PLAY to establish an RTSP. connection.
其中，RTSP客户端发送的DESCRIBE请求用于得到会话描述信息，SETUP请求用于提醒RTSP服务端建立会话并确定传输模式，PLAY请求用于向RTSP服务端发起播放请求。The DESCRIBE request sent by the RTSP client is used to obtain the session description information, the SETUP request is used to remind the RTSP server to establish a session and determine the transmission mode, and the PLAY request is used to initiate a play request to the RTSP server.
此外，需要说明的是，在RTSP客户端提供有设备控制界面，该设备控制界面提供有多个控件，与RTSP服务端支持的动作一一对应，用户通过该设备控制界面的控件即可触发用于请求RTSP服务端执行相应动作的设备控制请求。In addition, it should be noted that the RTSP client is provided with a device control interface, and the device control interface provides multiple controls, which are in one-to-one correspondence with the actions supported by the RTSP server, and the user can trigger the control through the device control interface. A device control request that requests the RTSP server to perform the corresponding action.
步骤S20，所述RTSP服务端通过建立的所述RTSP连接接收所述RTSP客户端基于接收的所述设备控制方法发送的设备控制请求，其中，所述设备控制请求包括除媒体流控制之外的其它控制请求；Step S20, the RTSP server receives, by using the established RTSP connection, a device control request sent by the RTSP client based on the received device control method, where the device control request includes: Other control requests;
步骤S30，所述RTSP服务端基于所述设备控制方法提取接收的所述设备控制请求所携带的控制参数，并执行所述控制参数对应的动作。Step S30: The RTSP server extracts the control parameter carried by the received device control request according to the device control method, and performs an action corresponding to the control parameter.
本实施例中，在RTSP客户端和RTSP服务端建立RTSP连接之后，用户可基于RTSP客户端提供的设备控制界面随时向RTSP服务端发送设备控制请求，所述RTSP服务端在接收到RTSP客户端发送的设备控制请求时，基于所述设备控制方法提取接收的所述设备控制请求所携带的控制参数，并执行所述控制参数对应的动作。例如，用户通过RTSP客户端向摄像头 (RTSP服务端)发送控制摄像头向左转动的设备控制请求，如下所示：In this embodiment, after the RTSP connection is established between the RTSP client and the RTSP server, the user can send a device control request to the RTSP server at any time based on the device control interface provided by the RTSP client, and the RTSP server receives the RTSP client. When the device control request is sent, the control parameter carried by the received device control request is extracted based on the device control method, and the action corresponding to the control parameter is executed. For example, the user goes to the camera through the RTSP client. (RTSP server) sends a device control request that controls the camera to rotate to the left as follows:
PTZ LEFTPTZ LEFT
RTSP/1.0RTSP/1.0
CSeq:7CSeq: 7
摄像头在接收到RTSP客户端发送的设备控制请求之后，提取该设备控制请求携带的控制参数，即“LEFT”，从而识别出该设备控制请求为“向左转动”的请求，并响应该设备控制请求，控制云台向左转动。同时，RTSP服务端返回该设备控制请求的响应，如下所示：After receiving the device control request sent by the RTSP client, the camera extracts the control parameter carried by the device control request, that is, “LEFT”, thereby identifying that the device control request is a “turn to the left” request, and responding to the device Control the request and control the pan/tilt to rotate to the left. At the same time, the RTSP server returns the response of the device control request as follows:
RTSP/1.0 200 OKRTSP/1.0 200 OK
CSeq:7CSeq: 7
进一步的，在本实施例中，当用户不存在继续控制RTSP服务端的需求时，可基于RTSP客户端向所述RTSP服务端发送TEARDOWN请求，以断开RTSP客户端与RTSP服务端之间的RTSP连接，该TEARDOWN请求如下所示：Further, in this embodiment, when the user does not have the requirement to continue to control the RTSP server, the RTSP client may send a TEARDOWN request to the RTSP server to disconnect the RTSP between the RTSP client and the RTSP server. Connection, the TEARDOWN request is as follows:
TEARDOWN rtsp://192.168.1.3:5000/***RTSP/1.0TEARDOWN rtsp://192.168.1.3:5000/***RTSP/1.0

本领域技术人员应当理解的是，RTSP客户端除了基于建立的RTSP连接向RTSP服务端发送设备控制请求之外，还可以向RTSP服务端发送流媒体控制请求，用于对RTSP服务端进行正常的媒体流控制。It should be understood by those skilled in the art that the RTSP client can send a media control request to the RTSP server in addition to sending a device control request to the RTSP server based on the established RTSP connection, for performing normal operation on the RTSP server. Media flow control.
本实施例提出的终端控制方法，在RTSP客户端和RTSP服务端建立RTSP的连接过程中，由RTSP服务端向RTSP客户端返回包括预设的设备控制方法的OPTION响应。在建立RTSP连接后，若RTSP客户端存在对RTSP服务端进行除媒体流控制之外的其它控制需求，可按照所述设备控制方法规定的格式基于建立的RTSP连接返回设备控制请求，供RTSP服务端基于所述设备控制方法提取接收的所述设备控制请求所携带的控制参数，并执行所述控制参数对应的动作。相较于现有技术，本发明在需要对RTSP服务端进行除媒体流控制之外的其它控制时，可直接利用已经建立的RTSP连接进行设备控制请求的传输，而无需建立新的专用连接发送设备控制请求，也不需要借助额外的专用服务器转发设备控制请求，能够达到降低网络消耗的目的。In the terminal control method provided in this embodiment, in the process of establishing an RTSP connection between the RTSP client and the RTSP server, the RTSP server returns an OPTION response including a preset device control method to the RTSP client. After the RTSP connection is established, if the RTSP client has other control requirements other than the media stream control for the RTSP server, the device control request may be returned based on the established RTSP connection according to the format specified by the device control method, for the RTSP service. The terminal extracts the control parameter carried by the received device control request according to the device control method, and performs an action corresponding to the control parameter. Compared with the prior art, the present invention can directly use the established RTSP connection to perform device control request transmission without requiring a new dedicated connection to be sent when the RTSP server needs to perform other control than the media stream control. The device control request does not need to use an additional dedicated server to forward device control requests, which can reduce network consumption.
进一步的，基于第一实施例，提出本发明终端控制方法的第二实施例，参照图3，在本实施例中，步骤S10之前，还包括：Further, based on the first embodiment, a second embodiment of the terminal control method of the present invention is proposed. Referring to FIG. 3, in the embodiment, before step S10, the method further includes:
步骤S40，在接收到RTSP客户端发送的OPTION请求时，所述RTSP服务端提取并基于所述OPTION请求携带的鉴权信息对所述RTSP客户端进行鉴权操作；Step S40: Upon receiving the OPTION request sent by the RTSP client, the RTSP server extracts and performs an authentication operation on the RTSP client based on the authentication information carried by the OPTION request.
在鉴权通过时，执行步骤S10。When the authentication is passed, step S10 is performed.
需要说明的是，本实施例与第一实施例的区别在于，为避免任何RTSP客户端连接RTSP服务端均可对RTSP服务端进行除媒体流控制之外的其它控制，本实施例还需要对RTSP客户端进行鉴权操作，并仅对鉴权通过的RTSP客户端提供除媒体流控制之外的其它控制服务。It should be noted that the difference between this embodiment and the first embodiment is that in order to prevent any RTSP client from connecting to the RTSP server, the RTSP server can perform other control than the media stream control. The RTSP client performs the authentication operation and provides only the control services other than the media stream control for the RTSP client through which the authentication is passed.
在本实施例中，RTSP服务端在接收到RTSP客户端发送的OPTION请求 时，首先提取并基于所述OPTION请求携带的鉴权信息对所述RTSP客户端进行鉴权操作，具体的，用户基于RTSP客户端在RTSP服务端预先注册有用户名以及密码，在建立RTSP连接时，RTSP客户端发送的OPTION请求中将携带有用户预先注册的用户名以及密码作为鉴权信息；相应的，RTSP服务端在接收到RTSP客户端发送的OPTION请求时，将提取接收的OPTION请求携带的用户名及密码(鉴权信息)，并判断该用户名及密码是否为预先注册的用户名及密码，是则鉴权通过，否则鉴权失败，需要说明的是，RTSP协议中的鉴权通常发生在DESCRIBE请求阶段，本发明实施例对此不作限定。In this embodiment, the RTSP server receives the OPTION request sent by the RTSP client. Initially, the RTSP client is first authenticated and authenticated based on the authentication information carried by the OPTION request. Specifically, the user pre-registers the user name and password on the RTSP server based on the RTSP client, and establishes an RTSP connection. The OPTION request sent by the RTSP client will carry the user name and password pre-registered by the user as the authentication information; correspondingly, the RTSP server will extract the received OPTION request when receiving the OPTION request sent by the RTSP client. Carrying the user name and password (authentication information), and judging whether the user name and password are pre-registered user names and passwords, then the authentication is passed, otherwise the authentication fails. It should be noted that the RTSP protocol The rights usually occur in the DESCRIBE request phase, which is not limited by the embodiment of the present invention.
进一步的，本实施例中，步骤S40之后，还包括：Further, in this embodiment, after step S40, the method further includes:
