Abstract
The invention discloses a kind of self-defined reallocating method of serial port and device, the re-matching device includes serial equipment allocation unit, serial equipment access control unit, serial equipment address resolution unit.The serial bus of serial equipment is accessed re-match device first by the method, device is distinguish multiple serial equipments distribution address of access, send serial equipment address lookup data, it re-matches device and cuts off serial equipment regular path, the corresponding serial equipment of parsing inquiry Address Recognition, and its address is returned to by the serial ports, computer is according to the serial port of return address, the correspondence of serial port and serial equipment is established, modification serial port is self-defined, restores serial equipment regular path.The present invention can recognize that identical serial equipment, and establish the correspondence of serial port and equipment, and change the serial port of all serial equipments automatically, solves computer operating system and is difficult to serial port and the correspondence of equipment this technical problem.
Description
Technical field
The invention belongs to serial communication field, it is related to a kind of self-defined reallocating method of serial port and device.
Background technology
The serial port of serial equipment would generally become with the port of connection equipment and the variation of computer operating system
Change, meanwhile, for multiple identical serial equipments, computer operating system is difficult to the correspondence of serial port and equipment,
These are uncertain so that the application for serial ports needs to change therewith, brings greater inconvenience to application.
Invention content
In view of this, a kind of self-defined reallocating method of serial port of present invention offer and device, to solve current serial equipment
Applying upper inconvenience.
The invention is realized by the following technical scheme：
A kind of self-defined re-matching device of serial port, including：
Serial equipment allocation unit distributes different addresses for multiple serial equipments to access；
Serial equipment address resolution unit, for the address lookup data that analytical Calculation machine is sent, according to serial equipment
The corresponding serial equipment of Address Recognition of location allocation unit distribution, and the address date of the serial equipment is sent back into computer；
Serial equipment access control unit, for controlling cutting for serial equipment normal communication state and address lookup state
It changes.
A kind of self-defined reallocating method of serial port, includes the following steps：
Step 1：The serial bus of serial equipment accesses serial equipment allocation unit, serial equipment allocation unit
Different addresses is distributed to multiple serial equipments of access；
Step 2：Computer sends serial equipment address lookup data to serial equipment address resolution unit；
Step 3：Serial equipment access control unit cuts off serial equipment regular path；
Step 4：Serial equipment address resolution unit parses address lookup data, identifies corresponding serial equipment, and pass through
The serial ports returns to its address；
Step 5：Computer establishes the correspondence of serial port and serial equipment according to the serial port of return address；
Step 6：It is self-defined serial port that computer changes serial port according to correspondence；
Step 7：Serial equipment access control unit restores serial equipment regular path.
Further, when multiple serial equipments access, step 1-7 is repeated, multiple serial ports are changed using batch processing.
Advantageous effect of the present invention：
The present invention can recognize that identical serial equipment, and establish the correspondence of serial port and equipment, and change all strings
The serial port of jaws equipment, solves that computer operating system is difficult to serial port and the correspondence of equipment this technology is asked
Topic.
Specific implementation mode
The present invention is described in detail below.
A kind of self-defined re-matching device of serial port of the present invention, including：
Allocation unit：Each equipment is given to distribute address first, this is the basis of all operations.
Computer sends address lookup data.This data contains the address information of equipment.
Access control unit：Serial equipment has 2 working conditions, and one is used for normal communication, and one is used for address lookup.
When computer sends address lookup data, which can place a device in inquiry state.
Address resolution unit：When equipment is in inquiry state, resolution unit parses address information, by the ground of corresponding equipment
Location data send back computer by the equipment.
Include 2 identical serial equipment A, B in the present embodiment.A, the serial ports of B in a computer be respectively COM12,
COM15.A/B and COM12/COM15 correspondences are unknown.The equipment is as the self-defined re-matching dress of serial port provided by the present invention
Set and method implement object.
Implementation is as follows：
Step 1：The serial bus access of serial equipment A, B re-match device, and address is respectively 0A, 0B；
Step 2：Computer sends the address lookup data A5A5 01 of serial equipment A by control interface to re-matching device
0A.Wherein 01 indicates that this group of data are querying command, and 0A indicates the serial equipment that inquiry address is 0A.
Step 3：It re-matches device and cuts off serial equipment A, B regular path；
Step 4：Re-match 01 0A of device parsing data A5A5, and by the serial ports of device A to computer transmission data 0A；
Step 5：Computer inquires the data that COM12 and COM15 are received respectively, receives then being established with A equipment pair for 0A
It should be related to.If COM12 receives 0A, then A equipment corresponds to COM12；
Step 6：The step of repeating front, establishes B device and the correspondence of COM15；
Step 7：Using the corresponding serial ports of batch processing modification A and B.If COM12 is changed to COM7, COM15 is changed to COM8.It repaiies
Change rear A and correspond to COM7, B corresponds to COM8.
Step 8：Re-match the regular path that device restores serial equipment A, B.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification made, equivalent replacement, improvement etc. should be included in the present invention's
Within protection domain.
