Description
Technical field
The present invention relates to electronic communication field more particularly to a kind of embedded intelligence serial ports detection methods.
Background technology
When software is required for serial communication before being operated to computer serial port or built-in terminal serial ports in conventional method,
Operating personnel are first wanted to find the serial ports for belonging to the built-in terminal in computer equipment manager, in the process computer itself
Serial interface is had, other serial communication equipment is also had and is inserted into computer, operator cannot quickly and accurately find out embedding
Serial ports corresponding to embedded system；After being correctly found embedded affiliated serial ports, corresponding equipment of serial number, then logical software are recorded
The interface that interface provides, opens the serial ports manually, finally realizes sending and receiving by serial data, searches and open serial ports
It is relatively loaded down with trivial details, and user must also have certain Computer Basic Knowledge to open equipment manager, to allow user
It is operated when using embedded system relatively difficult.The invention also further solves serial ports after opening, by open
Serial ports is realized in communication process can grasp serial ports working condition in real time, abnormal to simple serial ports to be repaired by software,
Success repair after can normal use serial ports is carried out to user and abnormal information alert occurs if serial ports cannot be repaired successfully.
To solve the above-mentioned problems, the present invention proposes a kind of embedded intelligence serial ports detection method.
Invention content
To solve the above-mentioned problems, the present invention proposes a kind of embedded intelligence serial ports detection method.
Specifically, a kind of embedded intelligence serial ports detection method, comprises the steps of：
S1 detects identical with target serial ports type serial ports, and counts and preservation can use serial ports list；
S2 opens the serial ports not detected in an available serial ports list and is sent to Handshake Protocol；Whether judge serial ports
There is return information；There is no return information then to turn S4；
S3, judges whether return information meets protocol specification；Meet, turns S5；
S4 closes current serial ports；Judge to have detected whether serial ports quantity is more than the serial ports number counted；It is no, then turn S2；It is then to turn
S8；
S5, serial ports are opened successfully, are started to communicate, are turned S6；
Whether S6, it is normal to monitor the serial communication, and serial ports normally then turns S7, abnormal then current serial ports is closed and restarted beat again
It opens, opens and successfully turn S5, opening unsuccessfully turns S8；
S7, communicates normal termination, and return communication completes information；Process terminates；
S8, abnormal ending return to error message；Process terminates.
Preferably, Handshake Protocol is sent described in S2 and judges to be additionally provided with waiting between whether serial ports has return information
Time judges by accident for preventing.
Preferably, the protocol specification described in S3 is the protocol specification of user's selection or the agreement that system automatically selects
Specification.
Preferably, S1 is gone to after opening failure described in S6, restarts serial ports detection.
Preferably, further include prompt message and help information in the error message returned in the S8；The prompt message
Failure information or serial ports exception information are opened including serial ports.
Preferably, S5 serial ports is normally opened and is started in communication process, and system can be with secondary communication protocol handshaking party
Formula communicated in serial ports monitoring state, serial ports normally then turns S7, abnormal then current serial ports is closed and restarted beat again
It opens, opens and successfully turn S5, opening unsuccessfully turns S8.
The beneficial effects of the present invention are：The present invention can automatically open the affiliated serial ports of built-in terminal, exclude computer
In other available and non-targeted built-in terminal serial ports, do not need user go manually open computer in equipment manager look into
It sees serial ports numbering equipment, finds out available serial ports number in current computer automatically by software, and do not verified.It simplifies
User's operation improves user to system usage experience.
Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control illustrates this hair
Bright specific implementation mode.
A kind of embedded intelligence serial ports detection method, comprises the steps of：
S1 detects identical with target serial ports type serial ports, and counts and preservation can use serial ports list；Herein for serial ports type
Judgement, either the hardware equipment information based on serial ports, can also be the identification information provided based on drive software；
S2 opens the serial ports not detected in an available serial ports list and is sent to Handshake Protocol；Whether judge serial ports
There is return information；It prevents from judging by accident, can suitably increase certain stand-by period herein.There is no return information then to turn S4；
S3, judges whether return information meets protocol specification；Meet, turns S5；Protocol specification herein can be user's selection
Protocol specification or system automatically select and matched protocol specification.
S4 closes current serial ports；Judge to have detected whether serial ports quantity is more than the serial ports number counted；It is no, then turn S2；It is,
Then turn S8；
S5, serial ports are opened successfully, are started to communicate, are turned S6；
Whether S6, it is normal to monitor the serial communication, and serial ports normally then turns S7, abnormal then current serial ports is closed and restarted beat again
It opens, opens and successfully turn S5, opening unsuccessfully turns S8；As a preferred option, S1 can be gone to after opening failure, restarts serial ports
Detection；But the cycle-index at this should be given and limit, and to avoid repetitive cycling, cause the stand-by period long.
S7, communicates normal termination, and return communication completes information；Process terminates；
S8, abnormal ending return to error message；Process terminates.
Preferably, further include prompt message and help information in the error message returned in the S8；The prompt message
Failure information or serial ports exception information are opened including serial ports.Such as：Prompt user checks whether that the serial ports is normally inserted into
Arrive computer etc..
As preferred embodiment, the opening side of serial communication the status monitoring step and S1-S5 of wherein step S6-S8
Formula phase is independent, i.e. step S6-S8 can be applied to the serial ports that monitoring has already turned on and communicates, but the unfolding mode of its serial ports is not necessarily
For the unfolding mode of S1-S5.
It should be noted that for each embodiment of the method above-mentioned, for simple description, therefore it is all expressed as to a system
The combination of actions of row, but those skilled in the art should understand that, the application is not limited by the described action sequence, because
For according to the application, certain some step can be performed in other orders or simultaneously.Secondly, those skilled in the art also should
Know, embodiment described in this description belongs to preferred embodiment, involved action and unit not necessarily this Shen
It please be necessary.
In the above-described embodiments, it all emphasizes particularly on different fields to the description of each embodiment, is not described in some embodiment
Part, may refer to the associated description of other embodiment.
One of ordinary skill in the art will appreciate that realizing all or part of flow in above-described embodiment method, being can be with
Relevant hardware is instructed to complete by computer program, the program can be stored in computer read/write memory medium
In, the program is when being executed, it may include such as the flow of the embodiment of above-mentioned each method.Wherein, the storage medium can be magnetic
