In the present embodiment, the hardware configuration of flush type WEB server mainly is made up of cpu chip, MPEG-4 audio/video coding chip, Flash chip, sdram memory, Ethernet interface and big capacity hard disk.Wherein CPU adopts the PowerPC series embedded communication processor MPC8250 of MOTOROLA company.MPEG-4 audio/video coding chip is accomplished compression of video data and the coding to sending from camera.According to the network bandwidth, topological structure and to the requirement of picture quality, native system is selected the layering scalable coding scheme based on the MPEG-4 standard for use.Video data after the compression can be stored in the big capacity hard disk as required, perhaps carries out Network Transmission through Ethernet.In order to realize the video storage function, need to adopt jumbo hard disk.
The software design of flush type WEB server is one of key of native system realization with realization, comprises embedded OS and application software two large divisions.
Embedded OS is to support embedded system applied operating system software, is the special purpose operating system that outstanding feature is arranged at aspects such as system real time, hardware dependency and software solid states.Native system adopts flush type LINUX operating system, and it is on the basis of LINUX operating system being carried out miniaturization cutting and real time implementation according to system's needs, to realize.Use the advantage of LINUX to be: the source code of its operating system is open, can customize as required; System kernel is little, thereby low relatively to the requirement of hardware; Support the multitask multi-process, good real-time performance can be provided.
The application software architecture of server mainly is made up of several piths such as WEB server, cgi script, video dispatching and transport module, storage administration and scheduler module, video camera control modules.
The WEB server carries out information interaction through http protocol and monitoring client browser software, and interface and the video data browser interface and the video camera control interface of other application program modules is provided.In addition, it also will be controlled the access rights of monitoring client, filters the request and the control information of monitoring client, handles the synchronous and issue of priority of the request and the control of a plurality of monitoring clients.Native system has adopted CGI to realize dynamic WEB technology, and CGI has stipulated the interface protocol standard of other executable programs of WEB server calls (cgi script).The WEB server is realized mutual with browser through calling cgi script, and just cgi script is accepted the information that browser sends to the WEB server, handle, with response results again loopback give WEB server and browser.Cgi script can be write with any programming language in principle, but has characteristics such as execution speed is fast, fail safe height with the cgi script of C language.
Video dispatching and transport module are that monitoring client provides required real-time video information, are most important modules in the server application software.This module connects according to the Network Transmission of being taked and control protocol and monitoring client, monitors the request of monitoring client; Take corresponding scheduling strategy to create video flowing according to different COSs again simultaneously, with video data packets, packing, send to monitoring client then, and carry out mistake processing and congested control according to the network state information of router and monitoring client feedback.
The UDP network communication protocol is generally adopted in the transmission of video data; And the IP load mode that adopts UDP has three kinds of program request, broadcasting and multicasts; Wherein multicast is that server only sends a packet to the particular user group; Each user in the group can share this packet, and the outer user of group can't receive.Native system adopts IP multicast mode, adopt the advantage of multicasting technology have following some: the video data that can let server bear a large amount of clients is broadcast requirement; Because the packet number of copies is few with the transmission destination address, has significantly reduced the data total amount of transmission through network, thereby has guaranteed higher service quality; Reduce the bandwidth occupancy of transmission of streams of video data, alleviated load of server.
The network transmission protocol that native system adopts is used the RTP/UDP/IP model.Real-time Transport Protocol is a kind of agreement that provides end-to-end real-time media transmission to serve, and is made up of realtime transmission protocol RTP and two parts of RTCP Real-time Transport Control Protocol RTCP.RTP is used for the transmission of real time video data, and RTCP then is used for monitoring the transmission of real time video data.Real-time and QoS that the mode of RTP/UDP/IP has been taken into account video transmission guarantee.To the uncertainty of transmission network situation, can also take certain congested control and error control strategy simultaneously.
The major function of memory management module is that the video information behind compression and the coding is stored to zone specific in the disk according to certain strategy; And video file information stored in the embedded database; For retrieval and playback; Respond the request of video dispatching and transport module simultaneously, according to certain disk scheduling policy and priority orders from disk reading video data to core buffer.For storage administration, native system adopts isometric packet memory strategy, is about to video information and is divided into the plurality of data unit according to sequential relationship, and these data cells are called grouping, with each packet memory in a fixed-size memory cell.
The video camera control module mainly realizes the control to video camera.At monitoring client; The user sends the video camera control command through browser to the WEB server; This control command is after the WEB server is accepted and handled; Send to the video camera control module through cgi script again, be converted into the hardware operation instruction of accordingly video camera being controlled then, thereby realize Long-distance Control the camera pan-tilt camera lens.
