By this means, on-site image acquisition and remote image wireless transmission are realized, the problems that live environmental reforms are difficult, wireless costs are high and the conditions are harsh are overcome, and the image acquisition wireless transmission system has the characteristics of low cost, small size, convenient layout, stable operation, and the like.

Description

IMAQ wireless transmitting system

Technical field

The utility model relates to IMAQ field, particularly relates to a kind of IMAQ wireless transmitting system.

Background technology

Along with developing rapidly of network and the communication technology, remote supervision system has very important meaning in industrial control field.At industrial control field, because the region of needs monitoring is wide, the object of monitoring is of a great variety, need to spend a large amount of man power and materials, moreover, in the local image data of many inclement conditions or the difficult stop arriving or can not be permanent of people, be very inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of IMAQ wireless transmitting system, and the guarded region that is intended to solve industrial control field is wide, monitored object kind is many, spend the problem that people under a large amount of manpower and materials and mal-condition are difficult for image data.

For solving the problems of the technologies described above, as an aspect of the present utility model, provide a kind of IMAQ wireless transmitting system, comprising: camera, for gathering image; Godson 1B chip, is connected with camera; Wireless transmitter module, is connected with Godson 1B chip, for Godson 1B chip image after treatment is sent; Public network server, with wireless transmitter module wireless connections.

Further, frame buffer, camera is connected with Godson 1B chip by frame buffer.

Further, IMAQ wireless transmitting system also comprises: NAND gate, the first input end of NAND gate is connected with the line synchronizing signal end of camera, the second input of NAND gate is write enable signal end with the frame buffer of Godson 1B chip and is connected, and the output of NAND gate is connected with the Enable Pin of writing of frame buffer.

Further, IMAQ wireless transmitting system also comprises serial ports conversion chip, and the serial ports of Godson 1B chip is connected with camera by serial ports conversion chip.

Further, IMAQ wireless transmitting system also comprises active crystal oscillator, is connected with frame buffer 3.

Further, wireless transmitter module is GPRS module.

When work, Godson 1B chip receives the image arriving from camera collection, and the image that it is received processes (for example, compression packing etc.), then image after treatment is transmitted to public network server by wireless transmitter module.Like this, just can be by wireless mode, realize collection and the remote image wireless transmission of image scene, overcome site environment transformation difficulty, wiring cost is high, the problems such as inclement condition, have the features such as cost is low, volume is little, laying is convenient, stable.

Embodiment

Below embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of IMAQ wireless transmitting system, comprising: camera 1, for gathering image; Godson 1B chip 2, is connected with camera 1; Wireless transmitter module 4, is connected with Godson 1B chip 2, for Godson 1B chip 2 images after treatment are sent; Public network server 7, with wireless transmitter module 4 wireless connections.Preferably, wireless transmitter module 4 is GPRS module.

When work, Godson 1B chip 2 receives the image collecting from camera 1, and the image that it is received processes (for example, compression packing etc.), then image after treatment is transmitted to public network server 7 by wireless transmitter module 4.Like this, just can be by wireless mode, realize collection and the remote image wireless transmission of image scene, overcome site environment transformation difficulty, wiring cost is high, the problems such as inclement condition, have the features such as cost is low, volume is little, laying is convenient, stable.

Preferably, frame buffer 3, camera 1 is connected with Godson 1B chip 2 by frame buffer 3.Preferably, frame buffer 3 can be AL422B etc.Solve message transmission rate inconsistence problems between Godson 1B chip 2 and camera 1 by frame buffer 3, between the two, added frame buffer 3, after the image buffer storage that camera 1 can be gathered, given again Godson 1B chip 2.

Preferably, IMAQ wireless transmitting system also comprises: NAND gate 5, the first input end of NAND gate 5 is connected with the line synchronizing signal end HREF of camera 1, the second input of NAND gate 5 is write enable signal end FIFO_WEN with the frame buffer of Godson 1B chip 2 and is connected, and the output of NAND gate 5 is connected with the Enable Pin/WE that writes of frame buffer 3.Preferably, NAND gate 5 can be 74HC00 etc.Can just produce and meet the sequential of writing that frame buffer 3 requires by NAND gate 5, thereby the image that camera 1 is exported automatically deposits frame buffer 3 in.
