Abstract
The utility model discloses a computer serial port control system, which comprises a main data transmitter, wherein the main data transmitter is provided with a data interface communicating with a computer. The computer serial port control system is also provided with a backup data interface and an auxiliary data transmitter, wherein the auxiliary data transmitter is provided with a data interface communicating with the computer; in addition, a backup data interface is arranged; a relay is embedded into the computer. The defect that the operation efficiency is extremely low is effectively avoided.
Description
Technical field
The utility model belongs to field of computer technology, is specifically related to a kind of serial ports of computers control system.
Background technology
In current serial ports transmission data, in general be divided into semi-duplex serial port and asynchronous transmission serial ports, and these two kinds of serial ports are widely used in same computer now, and semi-duplex serial port and asynchronous transmission serial ports operate while often needing difference in operation, and present technology is first to allow processor power down, then activate the operation of one of a shielding, the efficiency of operation is extremely low like this.
Summary of the invention
The utility model provides a kind of serial ports of computers control system, comprise master data transmitter, described master data transmitter is installed with the data-interface that same computing machine is conducted, also be provided with in addition Backup Data interface, also be provided with in addition secondary data link, secondary data link is installed with the data-interface that same computing machine is conducted, and is also provided with in addition Backup Data interface, also embeds and has relay in addition in computing machine.The efficiency of effectively having avoided strengthening operation is extremely low defect.
For achieving the above object, the technical solution of the utility model is:
A kind of serial ports of computers control system, comprise master data transmitter 1, described master data transmitter 1 is installed with the data-interface 3 that same computing machine 2 is conducted, also be provided with in addition Backup Data interface 4, also be provided with in addition secondary data link 5, secondary data link 5 is installed with the data-interface 6 that same computing machine 2 is conducted, and is also provided with in addition Backup Data interface 7, also embeds and has relay 8 in addition in computing machine 2.
The utility model compared with prior art, by described master data transmitter 1, the data-interface 3 that same computing machine 2 is conducted is installed, also be provided with in addition Backup Data interface 4, also be provided with in addition secondary data link 5, secondary data link 5 is installed with the data-interface 6 that same computing machine 2 is conducted, also be provided with in addition Backup Data interface 7, in computing machine 2, also embed and have relay 8 in addition, just can only need to just can realize at the situation lower-pilot relay of not power down of processor like this change of communication mode by the direct-cut operation of relay 8.
Accompanying drawing explanation
Fig. 1 is the structural representation of serial ports of computers control system of the present utility model.
