Entering online monitoring frontend is as server-side or client.This interface, which belongs to inside improved monitor supervision platform, to be connect
Mouthful, it is defined as follows:
The online request of equipment (user name, password ..., device service provide mode)；
Wherein, it is 0 that device service, which provides mode parameter, indicates monitoring frontend as server-side；Device service provides
Mode parameter is 1, indicates monitoring frontend as client；
Fig. 9 is the work flow diagram of front monitoring front-end according to an embodiment of the present invention (PU is as server-side), as shown in figure 9,
Any commercial server-side PU has to support service agreement disclosed at least one.ONVIF front monitoring front-end is exactly such
The typical case of type.Below with this for example: ONVIF front monitoring front-end is server-side, externally provides disclosed WebService
Service.Its service agreement specification can refer to: http://www.onvif.org/onvif/ver10/device/wsdl.
Step S902: protocol adaptation module PA pre-sets the IP address and service of ONVIF front monitoring front-end to be accessed
Port, the information such as oneself interested front end event type.When PA module starts, UDP probe message is sent according to protocol specification,
And receive the response of PU.Then equipment management essential information is obtained to it again, for using when follow-up equipment management.Similarly, it obtains
Take media management essential information (such as: front monitoring front-end support media protocol, such as RTCP/RTSP/RTP), be used for subsequent matchmaker
Body uses when managing.Later, PA initiates the subscription request of oneself interested event type to ONVIF PU.It should be noted that
The agreement that PA module and front monitoring front-end use when communicating is control protocol disclosed in front monitoring front-end.
Step S904: protocol adaptation module is after getting front monitoring front-end necessary information.To the business of monitoring system platform

Mode parameter is provided according to the device service filled in the online request of equipment, it is found that the monitoring frontend is server-side, then starts
Heartbeat keep alive timer, and the streaming media server (SS) inside monitor supervision platform is notified actively to go to request to the virtual monitor front end
Video code flow.Request is sent to PA module by SS, carries SS in request and receives the address of the code stream, port, streaming media
Layer protocol (such as: TCP/UDP) and control layer protocol (such as: RTCP/RTSP/RTP) information.PA records the address above mentioned of SS, end
After the information such as mouth, the agreement supported, protocol conversion is carried out, construction obtains video code flow and requests.Wherein, the ground of media code stream is received
Location, port information extend this as the address of PA oneself, port.The selection of streaming media layer protocol and control layer protocol is dependent on step
(such as: transport layer TCP, control layer protocol are RTSP/ to the media protocol type that the ONVIF PU got in rapid 201 is supported
RTP), the front end ONVIF PU is then sent the request to.
Step S908: after front monitoring front-end receives the code stream request of protocol adaptation module, the PA in analysis request receives media
Address, the port of code stream, streaming media layer protocol and control layer protocol (such as: RTSP/RTP) information, and to the address of PA,
Port sends the code stream for meeting the requirement of this media protocol.After PA receives video code flow, the conversion of media code stream protocol is carried out, and adopt
The media protocol supported with SS is to SS receives the address of media code stream, port sends bit stream data.
The technology that this step uses is the prior art.After completing the step, the code stream of front monitoring front-end has just accessed monitoring
Platform can be carried out the business such as take pictures and record a video inside monitor supervision platform in this way.
Step S910:, can be to the " virtual of access platform according to business needs in monitor supervision platform operational process
Front monitoring front-end " carries out equipment control (such as: Yun Jing control, equipment are restarted).SCP is that control command is directly handed down to agreement to fit
With module PA, control signaling is converted into the agreement that front monitoring front-end is supported by PA.Similarly, it when PA receives response, is also assisted
View conversion, and notify SCP.
After step S912:ONVIF PU generates the event (such as: certain type of alarm) that PA sense is lifted, to subscribing to this thing
The PA initiated event of part type notifies, is converted to monitor supervision platform internal agreement by PA, and event is notified to carry out at business to SCP
Reason.
Heartbeat keep alive timer on step S914:SCP service server then, then initiates heartbeat keep-alive request to PA,
ONVIF PU is sent to by the heartbeat keep-alive request that PA is converted to ONVIF PU support, also carries out protocol conversion simultaneously when receiving response
Heartbeat keep-alive response is returned to SCP.
Through above step, if monitor supervision platform will support a kind of server-side PU of new type, it is only necessary to develop, portion
Affix one's name to corresponding protocol adaptation module.
