Description
Technical field
The utility model relates to electronic technology field, and a kind of monitoring system device of the wired and wireless transmission based on digital processing unit is provided.
Background technology
Along with the development of science and technology and the raising of progress and people's material and cultural life, the degree of safety of people's living environment has had Secretary, thereby all kinds of security devices arise at the historic moment, and at home and abroad on market, the video acquisition device of most video monitoring safety-protection systems mainly contains two kinds at present:
The first adopts special image decoding chip automatically to complete the collection of image, and the time that processor is taken is few.But shortcoming is its grey scale accuracy to be restricted in the special image acquisition chip, and the video signal video adaptability that generally can only gather standard is bad, generally adopts the CPLD(CPLD) to control, integrated level is low, and circuit is complicated, and cost is high.
The second adopts screen special external high-speed A/D converter, and decoding is completed by logical device, and the interface of processor requirement and outside AD converter is also stored data.Shortcoming is need to carry out precision to clock signal to control, and processing capability in real time is poor.Circuit is complicated, and cost is high.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides that a kind of circuit is simple, with low cost, the monitoring system device of a kind of wired and wireless transmission based on digital processing unit that can carry out processing in real time.
The utility model is for achieving the above object by the following technical solutions:
a kind of monitoring system device of the wired and wireless transmission based on digital processing unit, it is characterized in that: comprise the camera that is linked in sequence, A/D video input chip, the DSP control chip, D/A video pio chip, the one GPRS module, also comprise the 2nd GPRS module, the monitoring display terminal, the CAN bus control unit, the CAN bus, described the 2nd GPRS module connects the monitoring display terminal, the one GPRS module and the 2nd GPRS module are carried out data interaction by GPRS network, described CAN bus control unit connects DPS control chip and monitoring CAN bus, the CAN bus connects the monitoring display terminal, described dsp chip is connected with jtag interface, data storage and FLASH memory.
The utlity model has following beneficial effect:
One, the utility model circuit is simple, and is with low cost, can process in real time, and the analog signal of output can be directly for the simulation demonstration.
Two, the utility model adopts wired and wireless 2 kinds of video signal transmission modes, makes the convenient applicable and various environment of whole system.
