Abstract
The utility model relates to a video monitoring system based on an FPGA. At present, the monitoring is mainly based on the PCs, and only the simple monitoring and recording functions are realized. The PCs need to be equipped with the large-capacity hard disks to store data, and the retention time of the general monitoring video is short. The video monitoring system based on the FPGA is composed of a wireless network camera (1), an infrared network camera (2), a network semi-dome camera (3) and a network high-speed intelligent dome camera (4), and is characterized in that the network semi-dome camera and the network high-speed intelligent dome camera are connected with a decoder (5) separately, the decoder, the wireless network camera and the infrared network camera are connected with an image acquisition device (6) separately, and the image acquisition device is connected with an image processing device (7); the image processing device is connected with a video matrix distributor (8), and the video matrix distributor is connected with a monitoring terminal device (9). The video monitoring system based on the FPGA of the utility model is used for the video monitoring.
Description
technical field:
the utility model relates to a kind of video monitoring system based on FPGA.
background technology:
along with the raising of people's living standard and the reinforcement of security precautions, video monitoring system is widely used in recent years.Yet current monitoring is main mainly with PC, just plays simple monitoring, writing function.Surveillance center need to have staff on duty, and monitors that for a long time screen easily produces visual fatigue.And PC need to be equipped with jumbo hard disk and carry out save data, general monitor video retention time is short, can only retain the time about one month, and what have is even shorter.
summary of the invention:
the purpose of this utility model is to provide a kind of video monitoring system based on FPGA.
above-mentioned object realizes by following technical scheme:
a kind of video monitoring system based on FPGA, its composition comprises: wireless network camera, infrared network video camera, network dome type camera, network high-speed Intelligent ball camera equipped, described network dome type camera, described network high-speed Intelligent ball camera equipped is connected with decoder respectively, described decoder, described wireless network camera, described infrared network video camera is connected with image collecting device respectively, described image collecting device is connected with image processing apparatus, described image processing apparatus is connected with video matrix distributor, described video matrix distributor is connected with monitor terminal device.
the described video monitoring system based on FPGA, described image processing apparatus comprises housing, described enclosure interior has field programmable gate array element, described field programmable gate array element is connected with central processing unit, described central processing unit is connected with data storage, program storage, ATA hard disk, warning device, ethernet interface circuit, display circuit, power circuit, and described display circuit is connected with the display screen being arranged on described housing.
beneficial effect:
central processing unit of the present utility model is to adopt dedicated multimedia chip TMS320DM642(to be called for short DM642), for receiving, processing Audio and Video data, expanding of system function is very convenient.In addition, the EMAC mouth that DM642 carries and the ATA mouth of expanding out from EMTF mouth, also for the mass data producing after finishing dealing with provides memory channel.
after the utility model powers on or resets, from program storage loading procedure, complete the work such as configuration to the initialization of chip and peripheral hardware, just start afterwards to carry out IMAQ.From camera collection to analog video signal be converted to digital video signal through Video Decoder, send into the video channel (VP port) of DM642.When detecting someone and enter monitor area, start recording function, DM642 is the digital video signal receiving and digital audio and video signals mpeg 4 standard compression coding, with the form of file, stores local ATA hard disk into, and confession is called in the future.Gather facial image simultaneously and carry out identification, if any extremely starting alert program.
the function of field programmable gate array element FPGA is mainly to realize the logic control of system and the sequencing control of memory.For realizing Real-time Collection and the processing of image, need the conversion of video and the processing concurrent working of image.Utilize field programmable gate array element FPGA internal resource to build high speed dual port RAM, Frame is processed and hocketed, thereby realize data acquisition, carry out with processing simultaneously.Field programmable gate array element FPGA adopts EP1C3T144, and its reading speed reaches 200MHz, is enough to meet the requirement of data processing.FPGA configuration has adopted specialized configuration chip EPCS1.
