Abstract
The utility model discloses an embedded video monitoring device, which comprises an ARM singlechip, a logic control circuit, an image data buffer, a monitoring camera and an I2C bus. The ARM singlechip is connected with the monitoring camera through the I2C bus and carries out initial setup for the monitoring camera to enable the monitoring camera to enter the normal working state. Image data output by the monitoring camera are stored in the image data buffer under the control of the logic control circuit. After a complete image of one frame is stored, the ARM singlechip closes an image output channel in the monitoring camera, and then the image data in the image data buffer are read in sequentially. The embedded video monitoring device adopts the I2C bus to connect the ARM singlechip and the monitoring camera, so that faster initial setup for the monitoring camera is enabled; and the single image data buffer is employed to store images picked up by the monitoring camera, so that access speed is faster.
Description
Technical field
The utility model relates to technical field of video monitoring, is specifically related to a kind of Embedded network video surveillance device.
Background technology
Video, image are the descriptions vivid, lively to objective things, are information representation forms directly perceived and concrete, are most important information carriers.Particularly in the information-intensive society of today, along with the fast development of network, communication and microelectric technique and the raising of people's living standard, the video monitoring characteristics such as directly perceived, convenient and content is rich with it are one of application technology focuses of paying close attention to of people always.It enriches because of directly perceived, convenient, the information content and is widely used.At present supervisory control system mainly is divided into the analog local signal supervisory control system and based on the digital monitor system of PC card, these two kinds of systems expose and need to repeat wiring in actual applications, and transmission range is short, and power consumption is high, needs the people on duty, the open shortcoming such as relatively poor of software.
The utility model content
For above-mentioned prior art, the technical problems to be solved in the utility model is: need to repeat wiring, collection, access speed slow.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of embedded video monitoring system device is provided, it is characterized in that, comprise ARM single-chip microcomputer, logic control circuit, image data buffer, monitoring camera and I
2The C bus, described ARM single-chip microcomputer passes through I
2The C bus is connected to monitoring camera, and monitoring camera is carried out the initialization setting, makes monitoring camera enter normal operating state, and the view data of monitoring camera output deposits in described image data buffer under the control of described logic control circuit; After the complete image of a frame deposited in, the ARM single-chip microcomputer cut out the image output channel in monitoring camera, then view data in image data buffer is read in order.
Described ARM single-chip microcomputer is 32 digit RISC micro controllers.
Described ARM single-chip microcomputer is connected with a network interface.
Compared with prior art, the utlity model has following beneficial effect:
One, adopt the I2C bus to connect ARM single-chip microcomputer and monitoring camera, initial setting up monitoring camera faster.
Two, the image storage that utilizes independent image data buffer that monitoring camera is taken, access speed is faster like this.
Three, by network interface can be on internet transmit image data, basically be not subjected to distance limit, need not rewiring; Be subject in addition other software and hardware impact in general-purpose computing system unlike the plug-in card system, and be convenient to install, safeguard.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
A kind of embedded video monitoring system device comprises ARM single-chip microcomputer, logic control circuit, image data buffer, monitoring camera and I
2The C bus, described ARM single-chip microcomputer passes through I
2The C bus is connected to monitoring camera, and monitoring camera is carried out the initialization setting, makes monitoring camera enter normal operating state, and the view data of monitoring camera output deposits in described image data buffer under the control of described logic control circuit; After the complete image of a frame deposited in, the ARM single-chip microcomputer cut out the image output channel in monitoring camera, then view data in image data buffer is read in order.Described ARM single-chip microcomputer is 32 digit RISC micro controllers.Described ARM single-chip microcomputer is connected with a network interface.
By network interface can be on internet transmit image data, basically be not subjected to distance limit, need not rewiring; Be subject in addition other software and hardware impact in general-purpose computing system unlike the plug-in card system, and be convenient to install, safeguard.The utility model from camera collection to Image Data Compression after, pack by network protocol stack and sends to network, the user can watch from client the image of this equipment collection in any place by the internet.
