Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of receiving front-end network digital video of realizing is provided, is put into the network monitoring video display devices that shows and control headend equipment on the display screen after it is decompressed by the control method that is similar to the traditional analog supervisory keyboard.
The utility model solves its technical problem and takes following technical scheme to realize:
This network monitoring video display devices, constitute by the control circuit in equipment and the equipment, control circuit comprises mixed-media network modules mixed-media, central processing module, display screen, three-dimensional rocker and function button, it is characterized in that: central processing module is connected mixed-media network modules mixed-media by address wire with data wire, this central processing module is by the display screen on the DIGITAL rgb interface connection device panel, and the GPIO of center processor module is by three-dimensional rocker and function button on the MCU7 module connection device panel.
And, between central processing module and mixed-media network modules mixed-media, also be connected with one needed reading and writing of mixed-media network modules mixed-media and chip selection signal control transformation logic module are provided.
And described mixed-media network modules mixed-media adopts the DM9000 chip, and central processing module adopts the EM8511 chip, and display screen adopts the very color LCDs of TFT of 320 * 240 resolution, and described control transformation logic module is the EPM3032 chip.
Advantage of the present utility model and beneficial effect are:
1. Jian Kong the scope and the degree of freedom are greatly improved, because computer network has spreaded all over all over the world at present, which can be connected to INTERNET easily at, and our equipment integrated Network Transmission, video-see and cradle head control function and profile lightly be easy to carry, can carry any old place insertion netting twine and just monitor and control, really realize " which is gone to can both be seen ".
2. cost is low, and is easy to operate.Adopt this equipment, the computer that has saved rear end in the network digital supervisory control system, make equipment cost and maintenance cost all reduce significantly, and this equipment and traditional supervisory keyboard are closely similar, identical on using method, use the people of traditional supervisory control system to need not extra training and be familiar with just can skillfully using native system.
3. the fail safe of network monitoring has obtained very big assurance.Owing to broken away from traditional computer monitoring mode, adopt embedded system, the system that makes is not easy to be subjected to computer virus infection and the hacker invades, the fail safe that has improved system greatly
