Abstract
The invention discloses a kind of data safeties based on screen character identification to obtain system, including data display screen, camera, Data Encrypting Transmission System, image procossing and character identification system, camera and Data Encrypting Transmission System, Data Encrypting Transmission System is connect with image procossing and character identification system, camera photographed data shows content transmission on screen to data encryption and Transmission system, data encryption and Transmission system are encrypted transferring content and are transmitted to image procossing and character identification system carries out Image Acquisition and character recognition, the present invention does not carry out physical connection with providing the computer systems and networks of data, computer system and network to providing data is avoided to generate security implication, also save the cost of mass data transmission.
Description
Technical field
The present invention relates to data transfer of computer security technology area more particularly to a kind of numbers based on screen character identification
System is obtained according to safety.
Background technology
With the continuous development of industrial automation technology, scattered control system is applied in electric system more and more widely
（DCS）, Distributed Control System is based on microprocessor, is disperseed using control function, display operation is concentrated, taken into account point and oneself
The blind controller system of new generation for the design principle controlled and synthesized and coordinated, and be read out to Operation of Electric Systems real time data
When, DCS system network there are more insecurity, insecurity have physical layer insecurity and network layer not
Safety factor, the insecurity of physical layer refer mainly to the variation of network physical characteristic and surrounding enviroment, caused by circuit and
The network equipment it is unavailable, and cause the unavailable of network system, the safety of physical layer is the premise of whole network system safety
Condition in network layer insecurity, has what is be ravesdropping between the superior and the subordinate's network data transmission circuit and LAN at the same level
It threatens, and there is also attack inside LAN, in addition, also management level insecurity, network be unable to do without the management of people,
Network security policy needs people to go to realize, in the entire network, people plays an important role.
In terms of the long-range reading analysis to Operation of Electric Systems real time data, to ensure the peace of Operation of Electric Systems system
Entirely, not allowing arbitrarily to access extraneous device, and establish dedicated transmission line, cost is higher, follow-up to promote cost higher, because
This, it is necessary to propose that a kind of data safety identified based on screen character obtains system, to reach safe and simple acquisition data
Purpose.
Invention content
Present invention solves the technical problem that：A kind of data safety identified based on screen character is provided and obtains system, with solution
Certainly when reading power equipment running state in real time, there is more insecurity in DCS system network.
Technical scheme of the present invention：
A kind of data safety based on screen character identification obtains system, including data display screen, camera, Data Encryption Transmission system
System, image procossing and character identification system, the camera are connect with Data Encrypting Transmission System, the Data Encryption Transmission
System is connect with image procossing and character identification system.
Stent is further included, described stent one end is fixed on four angles of data display screen, and the stent is another
One end is connect far from data display screen and with camera.
The camera lens face data display screen.
The Data Encrypting Transmission System connects with the connection mode of image procossing and character identification system for network communication
It connects.
The image procossing and character identification system include system host and image display panel, the system host with
Image display panel connects.
The content that the data display screen is shown is the digital table with vertical and horizontal straight line.
The data column distribution sequence of the digital table is by background computer unified definition.
Beneficial effects of the present invention：A kind of data safety identified based on screen character is provided and obtains system, including data
Display screen, camera, Data Encrypting Transmission System, image procossing and character identification system, camera photographed data show on screen
Content transmission is encrypted transferring content to data encryption and Transmission system, data encryption and Transmission system and is transmitted to image
Processing and character identification system carry out Image Acquisition and character recognition, the not computer systems and networks with offer data of the invention
Physical connection is carried out, computer system and network to providing data is avoided to generate security implication, also saves mass data biography
Defeated cost.
