Preferred embodiment one
This preferred embodiment provides a kind of front monitoring front-end cut-in method, the supervisory control system realized by this method, can realize different manufacturers video monitoring front-end access use, front monitoring front-end is had to good compatibility, and do not need to transform monitor supervision platform when supporting a kind of front monitoring front-end of newtype, thus larger reduction development cost.
In this preferred embodiment, the interface between video monitoring platform and front end watch-dog mainly comprises: equipment control, media management, incident management.
Wherein, equipment control refers to: front monitoring front-end is reached the standard grade or is rolled off the production line to the monitor supervision platform access; Monitor supervision platform is sent out control command and is carried out some actions (such as: Yun Jing controls, equipment is restarted etc.) to front monitoring front-end by it.
Media management refers to: the stream of video data of front monitoring front-end camera is routed to the streaming media server of monitor supervision platform (SS).Thereby can on the SS of platform, commence business (such as: take pictures, record a video).
Incident management refers to: front monitoring front-end to monitor supervision platform report some events (such as: alarm), platform need to be processed interested event according to self.
In the present embodiment, from the service of video monitoring front-end supplies a pattern, it can be divided into to two classes: as the front monitoring front-end of service end, as the front monitoring front-end of client.
After referring to this device power operation as the front monitoring front-end of service end, provide a kind of disclosed service (for example WebService), the role of video monitoring system is similar to client.Need to initiatively find front monitoring front-end, active obtaining facility information, the access of active request media by monitor supervision platform.The front monitoring front-end of this type starts application in recent years.A kind ofly as: ONVIF agreement is by many well-known manufacturers, combine and promote the international agreement of formulating.
Most of traditional front monitoring front-ends, as client, after this kind equipment powers on and moves, initiatively send the requests such as registration is reached the standard grade, media access, require to be linked into video monitoring platform.
The method of this preferred embodiment comprises following two aspects:
(1) improve existing supervisory control system function, line interface on expanding monitoring equipment, the parameter of existing upper line interface generally comprises: the authentication informations such as user name, password.On this basis, expand 1 parameter, indicating and will accessing the monitoring frontend of reaching the standard grade is as service end or client.
(2) for the monitoring frontend as service end, initiatively initiate the media access request by monitor supervision platform, initiatively the front end video code flow is linked into to the media server of monitor supervision platform inside.Simultaneously, by monitor supervision platform, initiatively initiate heartbeat keep-alive request, replied by front monitoring front-end.
For the monitoring frontend as client, initiatively initiate the media access request by front monitoring front-end, monitor supervision platform returns to the media access address to it, and then front monitoring front-end initiatively uploads to video code flow the media server of monitor supervision platform inside.Simultaneously, by front monitoring front-end, initiatively initiate heartbeat keep-alive request, monitor supervision platform is replied do heartbeat.
Preferably, for the front monitoring front-end of each type access monitor supervision platform, increase an independently protocol adaptation module, do translation conversion between the control protocol of supporting at monitor supervision platform internal control agreement and front monitoring front-end.Like this, monitor supervision platform, after carrying out the 1st step improvement, just need not be transformed monitor supervision platform for a kind of new monitoring frontend access again, only revises the protocol adaptation module for this type monitoring frontend.For monitor supervision platform, regard the protocol adaptation module of platform outside and front monitoring front-end as an integral body, i.e. " virtual monitor front end " in logic.
Preferred embodiment two
This preferred embodiment provides a kind of front monitoring front-end cut-in method, below in conjunction with Fig. 1 and Fig. 9, is elaborated.
As shown in Figure 1, be published traditional video surveillance system schematic.In such video monitoring system, front monitoring front-end initiatively requires to be linked into monitor supervision platform as client.Wherein, the target access server address of front monitoring front-end module in can the configuration monitoring platform just initiates to register to this address, the request of reaching the standard grade after powering on.Afterwards, on continuing, the video code flow that the active request media server provides by reference, and code stream is uploaded to monitor supervision platform.
In this preferred embodiment, improved line interface on the equipment of existing video monitoring platform.Usually, on existing equipment, the parameter of line interface generally comprises: the authentication informations such as user name, password.On this basis, expand 1 parameter, indicating and will accessing the monitoring frontend of reaching the standard grade is as service end or client.This interface belongs to the monitor supervision platform internal interface after improvement, is defined as follows:
The equipment request of reaching the standard grade (user name, password ..., device service supplies a pattern);
Wherein, the device service parameter that supplies a pattern is 0, means that monitoring frontend is as service end; The device service parameter that supplies a pattern is 1, means that monitoring frontend is as client;
Fig. 9 is the workflow diagram of the front monitoring front-end (PU is as service end) according to the embodiment of the present invention, and as shown in Figure 9, the service end PU of any commercialization must support at least one disclosed service agreement.The ONVIF front monitoring front-end is exactly the typical case of this type.Below take this for example explanation: the ONVIF front monitoring front-end is service end, and disclosed WebService service externally is provided.Its service agreement standard can reference: http://www.onvif.org/onvif/ver10/device/wsdl.
Step S902: protocol adaptation module PA pre-sets IP address and the serve port of ONVIF front monitoring front-end to be accessed, the information such as own interested front end event type.When the PA module starts, send the UDP probe message according to protocol specification, and receive replying of PU.And then obtain the equipment control essential information to it, while managing for follow-up equipment, use.In like manner, obtain the essential information (for example: the media protocol that front monitoring front-end is supported, as RTCP/RTSP/RTP) of media management, use while manage for subsequent media.Afterwards, PA initiates the subscribe request of own interested event type to ONVIF PU.The agreement of using while it should be noted that PA module and front monitoring front-end communication is the disclosed control protocol of front monitoring front-end.
Step S904: the protocol adaptation module is after getting the front monitoring front-end necessary information.Service server (SCP) the initiating equipment request of reaching the standard grade to monitoring system platform.Wherein, the device service parameter that supplies a pattern extends this as 0, means to have the application of the front monitoring front-end as a service end connecting system.For monitoring system platform, it is used as one " virtual monitor front end " to protocol adaptation module and front monitoring front-end and treats, and only with the PA module, carries out communication, by PA and ONVIF PU, carries out communication.
Step S906: after the monitor supervision platform service server SCP after improvement receives that equipment is reached the standard grade and asked and authenticate and pass through.According to the parameter that supplies a pattern of the device service of filling in the equipment request of reaching the standard grade; find that this monitoring frontend is service end; start heartbeat keep-alive timer, and the streaming media server (SS) of notice monitor supervision platform inside initiatively goes for and asks video code flow to this virtual monitor front end.Request sends to the PA module by SS, carries address, port that SS receives this code stream in the middle of request, the information such as streaming media layer protocol (as: TCP/UDP) and key-course agreement (as: RTCP/RTSP/RTP).PA carries out protocol conversion after recording the information such as agreement of address above mentioned, port, support of SS, and structure obtains the video code flow request.Wherein, the address of receiving media code stream, port information extend this as address, the port of PA oneself.The media protocol type (as: transport layer is TCP, and the key-course agreement is RTSP/RTP) that the ONVIF PU that the selective dependency of streaming media layer protocol and key-course agreement gets in step 201 supports, then send the request to ONVIF PU front end.
Step S908: after front monitoring front-end is received the code stream request of protocol adaptation module, address, the port of the PA receiving media code stream in analysis request, the information such as streaming media layer protocol and key-course agreement (as: RTSP/RTP), and send to address, the port of PA the code stream that meets this media protocol requirement.After PA receives video code flow, carry out the conversion of media code stream protocol, and the media protocol that adopts SS to support is to address, the port transmission bit stream data of SS receiving media code stream.
The technology that this step adopts is prior art.After completing this step, the code stream of front monitoring front-end has just accessed monitor supervision platform, just can be taken pictures and the business such as video recording monitor supervision platform is inner like this.
Step S910: in the monitor supervision platform running, according to service needed, can carry out to " the virtual monitor front end " of access platform equipment control (as: Yun Jing controls, equipment is restarted etc.).SCP directly is handed down to control command protocol adaptation module PA, by PA, control signal is converted to the agreement that front monitoring front-end is supported.In like manner, PA receives while replying, and also carries out protocol conversion, and notice is to SCP.
The event that step S912:ONVIF PU generation PA sense is lifted (such as: the alarm of certain type), the PA initiated event notice to subscribing to this event type, be converted to the monitor supervision platform internal agreement by PA, and event notice carried out to Business Processing to SCP.
Heartbeat keep-alive timer on step S914:SCP service server then; to PA, initiate heartbeat keep-alive request; the heartbeat keep-alive request that is converted to ONVIF PU support by PA sends to ONVIF PU, while receiving response, also carries out protocol conversion and returns to the heartbeat keep-alive to SCP and reply.
By top step, monitor supervision platform is if while supporting a kind of service end PU of newtype, only need exploitation, dispose corresponding protocol adaptation module and get final product.
