And achieve a kind of high performance embedded microprocessor based on ARM kernel and embedded reality
Time operating system；On the basis of image scene is monitored, embedded in graphics front-end and process
Function, the visual range monitored is realized moving object detection, and image scene is passed through
The mode of wired (Ethernet) or wireless (GPRS) sends to remote monitoring center；These are two years old
Plant transmission channel and be respectively adopted embedded Web Server technology and GPRS technology, remotely
Transmission is played make up mutually, transmission means acts on flexibly.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions:
It comprises the following steps:
1, image acquisition and the preprocessing function of system mainly completes original image and compression figure
The collection of picture, unpack, combine, subpackage and encapsulation etc., if photographic head is with The Cloud Terrace, the most right
The Cloud Terrace is controlled；
2, the motion detection function of system mainly realizes moving object detection and dynamic background updates,
And relevant alert message is issued Web server or report user；
3, the embedded web server of system mainly completes the sound of the connection request to client
Should, and by the image scene after compression be organized into webpage for information about and send, in order to use
Family browses；
4, the ethernet feature of system completes the foundation of wireline transmission channel, in order to user passes through
Network access system；
5, the GPRS function of system completes the foundation of wireless transmission channel, it is achieved long distance wireless number
According to transmission, with wire transmission based on Ethernet constitute two kinds convenient, flexible, make up mutually
Transmission means.
The operation principle of the present invention: system controls the image of digital camera floor, and adopts
Collection is converted into the original image after a given data form by photographic head.Then, ARM system is to former
Beginning view data carries out the moving object detection computing of adaptive background, i.e. occurs when front-end image
During the dangerous change being previously set, produce intrusion alarm；And carry out beating to raw image data
Bag transmission.The WebServer being simultaneously based on ARM is in the state of intercepting, and one has client link
Request, WebServer organization Web pages by photo site and sends to client for information about, and
Client is used to pull the image that technology upgrades in time in the page, in order to user monitors the feelings at scene
Condition.During system start-up, GPRS module sets up GPRS link automatically, for data transparent transmission.
If any invasion, then enable GPRS function and invasion picture or alarm signal sent to Surveillance center,
So that monitoring personnel make respective handling according to these field conditions.
Beneficial effects of the present invention: it with the technology of remote image monitoring system field present stage is
Reference, has designed and Implemented a kind of high performance embedded microprocessor based on ARM kernel
And embedded real-time operating system；On the basis of image scene is monitored, embedded in figure
As the function of front-end processing, the visual range monitored is realized moving object detection, and will be existing
Field picture sends to remotely monitoring by the way of wired (Ethernet) or wireless (GPRS)
Center；Both transmission channels have been respectively adopted embedded Web Server technology and GPRS
Technology, play in remote transmission make up mutually, transmission means acts on flexibly.
Detailed description of the invention:
This detailed description of the invention is by the following technical solutions: it comprises the following steps:
1, image acquisition and the preprocessing function of system mainly completes original image and compression figure
The collection of picture, unpack, combine, subpackage and encapsulation etc., if photographic head is with The Cloud Terrace, the most right
The Cloud Terrace is controlled；
2, the motion detection function of system mainly realizes moving object detection and dynamic background updates,

Picture, and gather and be converted into the original image after a given data form by photographic head.Then, ARM
System carries out the moving object detection computing of adaptive background to raw image data, i.e. works as front end
When the dangerous change being previously set occurs in image, produce intrusion alarm；And to original image number
According to carrying out packing transmission.The WebServer being simultaneously based on ARM is in the state of intercepting, and one has visitor
Family end linking request, WebServer organization Web pages is by photo site and sends for information about to visitor
Family end, and use client to pull the image that technology upgrades in time in the page, in order to user monitors
On-the-spot situation.During system start-up, GPRS module sets up GPRS link automatically, for data
Transparent transmission.If any invasion, then enabling GPRS function will invasion picture or alarm signal transmission
To Surveillance center, in order to monitoring personnel make respective handling according to these field conditions.
The function that this detailed description of the invention can realize is as follows:
A, the view data of two kinds of forms of camera collection can be controlled, usually bitmap (BMP)
Image and jpeg image.Reason for this is that the moving object detection for adaptive background
The image of computing must be BMP image, and the view data after compression is difficult to this algorithm competent；
And unpressed BMP image data amount is unsuitable for the most greatly the remote transmission of embedded system；As
BMP compression of images is become jpeg image by this ARM system, then needs to take substantial amounts of hardware money
The operation time of source and processor, seriously add the burden of ARM system, affect system
Normal function, therefore gives photographic head by compression of images work and completes；
B, the moving object detection that adaptive background can be realized and intrusion alarm function.As intelligence
The embedded image monitoring system of energyization, having fault-tolerant adaptive control function in systems is must
Right, it is one of the feature of this monitoring system；
C, WebServer based on embedded system can be realized build.Based on embedded operation
System μ C/OS-II and ICP/IP protocol stack frame go out network communication platform；
D, the dynamic image on-the-spot with webpage mode transmitting, monitoring can be realized and can upgrade in time.
This contributes to long-distance user only need to open IE browser, just on any PC connecting net
The field condition that can monitor；
E, can realize transmitting intruding image or alarm signal in GPRS mode.This needs design
GPRS data transport module, completes to set up GPRS link, transmit image and safeguard GPRS
The function of link；
F, the encapsulation of the BMP to view data, packing etc. can be realized process, different to adapt to
Functional requirement.
This detailed description of the invention with the technology of remote image monitoring system field present stage as reference,
A kind of high performance embedded microprocessor based on ARM kernel and embedding are designed and Implemented
Formula real time operating system；On the basis of image scene is monitored, embedded in graphics front-end
The function processed, realizes moving object detection to the visual range monitored, and by image scene
Send to remote monitoring center by the way of wired (Ethernet) or wireless (GPRS)；
Both transmission channels have been respectively adopted embedded Web Server technology and GPRS technology,
Remote transmission plays make up mutually, transmission means acts on flexibly.
The ultimate principle of the present invention and principal character and the present invention have more than been shown and described
Advantage.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments,
The principle that the present invention is simply described described in above-described embodiment and description, without departing from this
On the premise of bright spirit and scope, the present invention also has various changes and modifications, these change and
