Abstract
The present utility model discloses an embedded network video monitoring device. The device comprises an ARM one-chip microcomputer, an image acquisition module and a logic control circuit, the ARM one-chip microcomputer is used for realizing initial setting of a working register of an image sensor of the image acquisition module through an I2C bus and enabling the image sensor to enter into a normal working state, image data output by the image sensor is stored into a static RAM image data buffer under the control of the logic control circuit; and after one frame of complete image is stored, the ARM one-chip microcomputer is used for closing an image output channel of the image sensor, and reading the image data of the static RAM image data buffer according to a sequence. Through adopting the device, image data can be transmitted on the internet without distance restriction and rewiring; data transmission will not be influenced by other software and hardware of a general-purpose computer system, and the device is convenient to install and maintain; and users can watch images collected by the equipment from a client through the internet at any places.
Description
Technical field
The utility model relates to networking technology area, is specifically related to a kind of embedded type network video supervising 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 carrier.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, 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 repeat wiring in practical application, 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
To above-mentioned prior art, the technical problem that the utility model will solve is: need repeat wiring, transmission range is short, power consumption is high, software is open relatively poor, and needs the people on duty, use cost is too high.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of embedded type network video supervising device is provided, it is characterized in that, comprise ARM single-chip microcomputer, image capture module, logic control circuit, said ARM single-chip microcomputer passes through I
2The C bus is carried out the initialization setting to the work register of the imageing sensor in the image capture module; Make imageing sensor get into normal operating state; The view data of imageing sensor output deposits the static RAM (SRAM) image data buffer under the control of said logic control circuit; After treating that the complete image of a frame deposits in, the image output channel in the ARM single-chip microcomputer closing image transducer is read in view data in the static RAM (SRAM) image data buffer more in proper order.
Said ARM single-chip microcomputer is 32 digit RISC micro controllers based on the Ethernet application system.
Said image memory module adopts the address signal of two counters as the RAM single-chip microcomputer, divides collection and reads the clock signal of the IO pulse signal of sharp PCLK of two kinds of occasions or ARM as counter.
Compared with prior art, the utlity model has following beneficial effect:
One, can be on internet transmit image data, do not receive distance limit basically, need not rewiring; Be subject to other software and hardware influence in the general-purpose computing system unlike plug-in card system that kind in addition, and be convenient to install, safeguard;
Two, this equipment from camera collection to Image Data Compression after, send to network through the network protocol stack packing, the image that the user can watch this equipment to gather from client through the internet in any place.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further to describe below.
A kind of embedded type network video supervising device is characterized in that, comprises ARM single-chip microcomputer, image capture module, logic control circuit, and said ARM single-chip microcomputer passes through I
2The C bus is carried out the initialization setting to the work register of the imageing sensor in the image capture module; Make imageing sensor get into normal operating state; The view data of imageing sensor output deposits the static RAM (SRAM) image data buffer under the control of said logic control circuit; After treating that the complete image of a frame deposits in, the image output channel in the ARM single-chip microcomputer closing image transducer is read in view data in the static RAM (SRAM) image data buffer more in proper order.Said ARM single-chip microcomputer is 32 digit RISC micro controllers based on the Ethernet application system.The output interface of view data and control signal links to each other with the bottom circuit board through the mode of slot.Said image memory module adopts the address signal of two counters as the RAM single-chip microcomputer, divides collection and reads the clock signal of the IO pulse signal of sharp PCLK of two kinds of occasions or ARM as counter.Can be on internet transmit image data, do not receive distance limit basically, need not rewiring; Be subject to other software and hardware influence in the general-purpose computing system unlike plug-in card system that kind in addition, and be convenient to install, safeguard.This equipment from camera collection to Image Data Compression after, send to network through the network protocol stack packing, the image that the user can watch this equipment to gather from client through the internet in any place.
