Description
Technical field
This utility model belongs to signal transmission technology field, particularly relates to a kind of serial communication long haul optical transmission set.
Background technology
UART protocol is applied widely, is PC and very many application apparatus, automatic controlling device, communication equipment
General-purpose interface, in a lot of application scenarios, current serial communication UART communication transmission media generally uses 485 buses or leads to
Crossing the transmission of RS232 switching levels, usual ultimate range is less than 200m, and more than 200m, transmission has a large amount of error code, for mine
Control equipment, for marine charting equipment, it is impossible to realizes long-distance transmissions requirement.
Utility model content
This utility model is for above technical problem, it is provided that a kind of serial communication long haul optical transmission set, uses UART
Protocol conversion is optical transmission medium, and transmission range can be made to be promoted to 1km-10KM, and capacity is big, long transmission distance.
The technical solution adopted in the utility model is as follows, and a kind of serial communication long haul optical transmission set, including multiple
UART interface, PLD and optical module, described UART interface is bi-directionally connected with PLD, described compiles
Journey logical device is bi-directionally connected with optical module, and described optical module connects transmitting terminal and receiving terminal, described PLD
For becoming proprietary protocol layer to send to optical module with for multichannel UART signal multichannel UART data receiver Polymeric encapsulation
Resolving to single channel UART signal and be distributed to the UART interface of correspondence, described optical module has optical electrical translation function.
Preferably, described programmable logic device is CPLD or FPGA.
This utility model multichannel UART interface is converted into Large Copacity signal by protocol encapsulation, is passed at a distance by optical module
Defeated, solve (mine controls equipment, marine charting equipment), the restriction that UART transmission range is short under special scenes.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings, this utility model is introduced in detail, it will be appreciated that simply introduce this reality below
By novel detailed description of the invention, and do not lie in restriction protection domain of the present utility model.
As it is shown in figure 1, a kind of serial communication long haul optical transmission set, including multiple UART interface, programmable logic device
Part and optical module, described UART interface is bi-directionally connected with PLD, and described PLD is double with optical module
To connection, described optical module connects transmitting terminal and receiving terminal.
During use, at sending ending equipment, multichannel UART interface is connected to PLD, such as CPLD, FPGA, many
Road UART data receiver Polymeric encapsulation become proprietary protocol floor (frame head+data+verification data), the data cube computation after encapsulation extremely
Optical module, completes electro-optic conversion by optical module, sends the corresponding receiving end device to more than 1km, and opposite end optical module receives
After data, optical module resolves to the signal of telecommunication by opto-electronic conversion, and the signal of telecommunication uses CPLD or FPGA to receive the signal of telecommunication, finds frame
Head, and resolve data, resolve to single channel UART signal, and be distributed to corresponding UART receiving terminal, thus complete UART signal
Long-distance transmissions.
Using aggregate frame technology can conveniently configure UART interface number, UART interface can design multiple and not mutual shadow
Ring.
Embodiment of the present utility model simply introduces its detailed description of the invention, does not lies in and limits its protection domain.The industry
Technical staff under the inspiration of the present embodiment, may be made that some is revised, therefore all done according to this utility model the scope of the claims
Equivalence change or modification, belong in this utility model scope of the patent claims.
