Abstract
The utility model discloses a kind of data communication apparatus, including main frame, data communication relay plate, feature board.Data communication apparatus provided by the utility model, it is connected by the encryption data between main frame and data communication relay plate, encryption data connection between data communication relay plate and feature board, by data communication relay plate, can effectively in computer and function on the contrary between safe transmission data.
Description
Technical field
It is specifically a kind of between main frame and feature board the utility model is related to a kind of data communication apparatus
Communication device.
Background technology
Communication between main frame and feature board, industrial generally use serial communication interface（RS232 standards or
RS485 standards）.In the case where feature board is more, main calculation machine host will not provide enough serial line interfaces.Main frame is logical
RS232 serial ports can be often provided, RS485 serial ports will not be provided.
In order to allow main frame there are enough serial communication interfaces, universal serial bus may be used at present
（USB）The method for being converted into serial line interface, the method that multi-serial-port card can also be used.Universal serial bus（USB）It is converted into
For the method for serial line interface, the disadvantage is that universal serial bus（USB）It is commercial communications interface, commercial Application, which is not achieved, in reliability needs
The stability wanted.The method of multi-serial-port card can occupy more space the disadvantage is that needing more serial line interface line, in addition,
There is also Compatibility of Operating System problem and the problems of multi-serial-port card and computer host interface compatibility for multi-serial-port card.
Invention content
The utility model aiming at the above shortcomings existing in the prior art, provides a kind of data communication apparatus.
The utility model is achieved through the following technical solutions.
A kind of data communication apparatus, which is characterized in that including main frame, data communication relay plate, multiple feature boards,
Wherein：
Main frame, it includes network interfaces；
Data communication relay plate, it includes network interfaces and multiple serial line interfaces；
Multiple feature boards, it includes serial line interface, sequence number that each feature board has oneself exclusive.
Further, the main frame network interface, the network interface with data communication relay plate are controlled by transmitting
Agreement processed（Transmission Control Protocol, abbreviation TCP）Connection.Connected communication, use are asymmetric herein
Algorithm carries out data encryption.
Further, the serial ports of the serial line interface of the data communication relay plate and feature board connects.It is connected herein
Communication carries out data encryption using symmetry algorithm.
The utility model discloses data communication apparatus, main frame and data communication relay plate pass through eight core cables
Connection, data communication relay plate are placed on multiple feature boards in a cabinet, it is possible to reduce the quantity of connecting line between plate.Institute is active
Data communication between energy node uses cipher mode, can prevent leakage of information.
Description of the drawings
Fig. 1 is the structure chart of the utility model, in figure：Machine host is calculated based on 1,2 be data communication relay plate, and 3 be multiple
Feature board, 11 be cable, and 12 be serial connection, and 101 be the public key and private key of main frame, and 102 be data communication relay plate
Public key and private key, 103 be the communication key of feature board, the communication key of each feature board is different, and 200 is feature boards
The female key of communication, respectively reads over the communication key of plate, is generated by communication mother key 200.
Specific implementation mode
It elaborates below to the embodiments of the present invention：The present embodiment before being with technical solutions of the utility model
It puts and is implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
Present embodiments provide a kind of data communication apparatus, which is characterized in that relay including main frame, data communication
Plate, multiple feature boards, wherein：
Main frame 1, it includes network interfaces；
Data communication relay plate 2, it includes network interface and multiple serial line interfaces, it is logical that serial line interface can be made in data
It reads on relay plate, to save the use of connecting line；
Multiple feature boards 3, it includes serial line interface, sequence number that each feature board has oneself exclusive.
Further, the main frame network interface, the network interface with data communication relay plate pass through cable 11
Connection, data transmission use transmission control protocol（Transmission Control Protocol, abbreviation TCP）.It connects herein
On communication, using asymmetric arithmetic carry out data encryption, use key 101 and 102 complete data encrypting and deciphering.
Further, the serial ports of the serial line interface of the data communication relay plate and feature board is complete by serial connection 12
At serial connection 12 can use serial port connecting wire, can also be directly connected to using connection terminal, if straight using connection terminal
It connects in succession, the use of communication cable can be saved.Connected communication herein carries out data encryption, key using symmetry algorithm
103 complete the data encrypting and deciphering of serial connection.
Further, the data communication relay plate reads over female key 200, is added by the sequence number to each feature board
It is close, generate the communication key 103 of each feature board.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
