Abstract

The present invention is equipment which completes image sampling as well as transmit color message using a W77E58 singlechip, composed mainly of image sampling module ZM460, central data processing control module, GPRS radio communication module GR47, power supply module. The equipment controls the image sampling module as well as samples locale image by the central data processing data control module, and stores the image data in a data memory; in addition, the central data processing control module dials through the GPRS network by GPRS radio communication module and transmits the image data stored in the memory to user mobile telephone with multimedia message. The present invention has the advantage of high integration, simple solution, low cost, stable usage as well as convenient maintenance, and can be used to locale image control and guard against theft for enterprise as well as institute.

Description

A kind of device that utilizes single-chip microcomputer to come images acquired and send multimedia message

Technical field

The present invention relates to a kind of device that utilizes single-chip microcomputer to come images acquired and send multimedia message, this device relates to image acquisition, compression, and transmission, and how to utilize GPRS network to send multimedia message.

Background technology

At present, utilize public network transmission data be the most general also be most economical means, along with of the seamless covering of mobile GPRS network in various places, utilize GPRS network to transmit the selection that data are everybody present the bests, for example multimedia message and note are exactly to utilize a kind of distinctive mode of GPRS network transmission data at present, intelligent computer burglar alarm and remote reviewing control system (patent No. CN200410079982.4) disclose a kind of burglar alarm and remote reviewing control device, and the main part of the information transmit-receive processing center of this device is a microcomputer, palmtop PC or smart mobile phone.This device is feasible from present technical seeing, also is scheme commonly used at present, and weak point is to have high input, and it is also unstable to do monitoring in 24 hours with PC, if it is higher to change the industrial computer expense into, is unfavorable for application.

Summary of the invention

The object of the present invention is to provide a kind of device that utilizes single-chip microcomputer to come images acquired and send multimedia message, adopt 8 cheap single-chip microcomputers to finish visual collection, transmit and utilize the GPRS wireless transport module to finish the transmission of multimedia message as the core microcontroller.

The object of the present invention is achieved like this: a kind of device that utilizes single-chip microcomputer to come images acquired and send multimedia message, be formed by connecting by image acquisition module, data processing and control module, wireless communication module and power supply, data processing and control module is connected and composed by the single-chip microcomputer and the data storage of the two serial ports of band, single-chip microcomputer is connected with the digital signal processor of image acquisition module by serial ports 1, and single-chip microcomputer is connected with wireless communication module by serial ports 0.

Because adopt said structure, the present invention has the following advantages:

1, highly integrated

This device adopts modularized design, and integrated level height, whole device be by the image acquisition module, data processing and control module, and wireless transport module and power module four parts constitute.

2, scheme is succinct

Owing to adopt modularized design, make whole proposal succinct, realize easily.

3, with low cost

Owing to adopt 8 single-chip microcomputers as core microprocessors, greatly reduce the cost of device, penetration and promotion is used easily.

4, use is stable, easy to maintenance

Because the chip used technical grade chip that all adopts of whole device makes that whole device is stable, because the height of equipment is integrated, it is easy to connect to make device install, and safeguards easy to use.
