Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not
For limiting the application.
In one embodiment, as shown in Figure 1, providing a kind of serial ports test method, comprising the following steps:
Step 102, the serial ports mark of serial ports to be tested is obtained, serial ports to be tested includes main serial ports and from serial ports.
Serial ports to be tested refers to that the serial ports for needing to carry out serial communication test, serial ports to be tested can be communication pipe to be tested
The RS485 interface of reason machine, such as multiple RS485 serial ports on a communication manager.Main serial ports refers to the conduct in serial communication
The serial ports of information sender refers to the serial ports in serial communication as receiving party from serial ports.The mark of serial ports is used for table
The mark of different serial ports is levied, specifically, the mark of serial ports can be serial port, such as COM1, COM2 etc..
Step 104, it controls main serial ports and sends default message, preset message and carry target serial ports mark.
Message is the data cell exchanged in network with transmission, i.e. the website data block disposably to be sent, message includes
Complete data information to be sent.Main serial ports active transmission under external trigger presets message, presets message and carries use
The customized data information in family, such as control serial ports COM1 send default message.Target serial ports mark refers to information sender (such as
Main serial ports) when sending message, the mark of the specified communication object carried in message.
Step 106, the feedback message and the corresponding feedback duration of feedback message that main serial ports receives are obtained, feedback message is
Default message is received from serial ports and is parsed, when target serial ports mark from the serial ports of serial ports mark with matching, by target serial ports mark
Know the message that the serial ports that change is main serial ports identifies.
Feedback message refers to from serial ports when receiving the default message that main serial ports is sent, and responds the report that default message generates
Text, feedback duration refer to the response time of default message.Main serial ports sends default message as information sender；Make from serial ports
For receiving party, default message is received, and default message is parsed, feedback message is generated and feeds back to main serial ports.Feedback
Duration, which refers to from serial ports, receives default message to this period for sending feedback message from serial ports.For example, main serial ports COM1 is sent
Message A receives message A, and response message A to from serial ports COM2, COM2, generates message B and feeds back to COM1, receives and report from COM2
This period that literary A to COM2 sends message B is to feed back duration.
Receive the message and parsing that main serial ports is sent from serial ports, the target serial ports mark that parsing is obtained with from serial ports itself
Serial ports mark be compared, when target serial ports identify with from the serial ports of serial ports mark match when, by target serial ports mark change
It is identified for the serial ports of main serial ports, generates feedback message and feed back to main serial ports, to ensure the accurate of serial communication.For example, main serial ports
COM1 sends message A, and the target serial ports carried in message A is identified as the serial ports mark of COM2.Distinguish from serial ports COM2 and COM3
Receive message A simultaneously parse, from the serial ports of serial ports COM2 mark with target serial ports mark match, from the serial ports of serial ports COM3 identify and
Target serial ports mark mismatches.Therefore, the serial ports mark for main serial ports COM1, hair are changed from serial ports COM2 by target serial ports mark
Send feedback message to main serial ports COM1.
Step 108, it is in pre- when the message content of feedback message is matched with the message content of default message and feeds back duration
If when duration range, obtaining the normal test result of serial communication to be tested.
The message content of server parsing feedback message will feed back the message content of message in the message content of default message
It is matched, is in preset duration model when the message content of feedback message matches with the message content of default message and feeds back duration
When enclosing, the normal test result of serial communication to be tested is obtained.For example, the message content of the default message prestored in server is
1001, server parsing feedback message, obtain feedback message message content be 1001, then feedback message message content with
Both message contents of default message match.Specifically, main serial ports COM1 sends message A extremely from serial ports COM2, the report of message A
Literary content is that 1001, COM2 receives message A, and response message A, generates message B and feeds back to COM1, analytic message B obtains message B
Message content be 1001, feedback message B message content match with the message content of default message A and feed back duration in advance
If when duration range, obtaining main serial ports COM1 and communicating normal test result from serial ports COM2.
Above-mentioned serial ports test method, the serial ports by obtaining serial ports to be tested identify, serial ports to be tested include main serial ports and
It from serial ports, controls main serial ports and sends default message, preset message and carry target serial ports mark.Default message is received from serial ports and is solved
Target serial ports mark is changed the serial ports mark for main serial ports when target serial ports mark from the serial ports of serial ports mark with matching by analysis
Know, generates feedback message and send.Main serial ports receives feedback message, obtains the feedback duration of feedback message, when the report of feedback message
When literary content matches with the message content of default message and feeds back duration and be in preset duration range, serial communication to be tested is obtained
Normal test result.Serial ports test result can be automatically derived in this way, it is not necessary that by serial communication assistant, artificial click is adjusted
The efficiency of serial ports test can be improved in examination.
In one embodiment, as shown in Fig. 2, obtaining main serial ports after controlling the main default message of serial ports transmission and receiving
Feedback message and the corresponding feedback duration of feedback message before further include: step 204, target serial ports is identified and from serial ports
Serial ports mark is matched；Step 206, when target serial ports is identified with matching from the serial ports of serial ports mark, control will from serial ports
The mark change of target serial ports is that the serial ports of main serial ports identifies, and generates feedback message.Target serial ports is identified and the serial ports from serial ports
After mark is matched further include: when target serial ports is identified with mismatch is identified from the serial ports of serial ports, control is lost from serial ports
Abandon default message.For example, main serial ports COM1 sends message A, the target serial ports carried in message A is identified as the serial ports mark of COM2
Know, the content of message A is 1001, receives message A respectively from serial ports COM2 and COM3 and parses, and is identified from the serial ports of serial ports COM2
It matches with target serial ports mark, is mismatched from the serial ports of serial ports COM3 mark and target serial ports mark.It therefore, will from serial ports COM2
The serial ports that the mark change of target serial ports is main serial ports COM1 identifies, and sends feedback message to main serial ports COM1, loses from serial ports COM3
Abandon message A.
In one embodiment, the feedback message that main serial ports receives is obtained, feedback message is that default report is received from serial ports
Text simultaneously parses, and when target serial ports mark from the serial ports of serial ports mark with matching, target serial ports mark is changed as main serial ports
The message that serial ports identifies, comprising: obtain the feedback message that main serial ports receives, feedback message is that default report is received from serial ports
Text simultaneously parses, when the message of target serial ports mark and the message content and default message that match and parse from the serial ports of serial ports mark
When content matching, target serial ports mark is changed into the message identified for the serial ports of main serial ports.For example, main serial ports COM1 is sent
The target serial ports carried in message A, message A is identified as the serial ports mark of COM2, and the content of message A is 1001, from serial ports COM2
It receives message A respectively with COM3 and parses, match from the serial ports of serial ports COM2 mark with target serial ports mark, solved from serial ports COM2
Analysing obtained message content is 1001, mismatches from the serial ports of serial ports COM3 mark and target serial ports mark, solves from serial ports COM3
Analysing obtained message content is 1000.The message content for matching and parsing is identified from the serial ports of serial ports COM2 mark with target serial ports
It matches with the message content of default message, therefore, changes from serial ports COM2 by target serial ports mark as the serial ports of main serial ports COM1
Mark sends feedback message to main serial ports COM1.
In one embodiment, as shown in figure 3, obtaining the corresponding feedback duration of feedback message, comprising: step 302, record
The sending time of default message and the receiving time for feeding back message；Step 304, it according to receiving time and sending time, obtains
Feed back the feedback duration of message.The sending time of default message is T1, and the receiving time for feeding back message is T2, by feeding back message
Receiving time and default message both sending times ask difference obtain feedback message feedback duration, that is, feed back message feedback
Shi Changwei T2-T1.
In one embodiment, as shown in figure 4, obtaining feedback message that main serial ports receives and feedback message is corresponding anti-
After feedback duration further include: step 405, when the message content of feedback message and the message content of default message mismatches or feedback
When duration exceeds preset duration range, the test result of serial communication exception to be tested is obtained.For example, what is prestored in server is pre-
If the message content of message is 1001, server parsing feedback message, the message content for obtaining feedback message is 1000, then instead
Both the message content of message and the message content of default message is presented to mismatch.Specifically, main serial ports COM1 send message A to from
The message content of serial ports COM2, message A are 1001, and the sending time for presetting message is T1.COM2 receives message A, and responds report
Literary A generates message B and feeds back to COM1, and the receiving time for feeding back message is T2.The message content that analytic message B obtains message B is
1000, the message content of the message content and default message A that feed back message B mismatches, and obtains main serial ports COM1 and from serial ports
The test result of COM2 communication abnormality.Or feedback duration is when being not at preset duration range, such as when feedback a length of (T2-T1)
It is not at preset duration range, obtains main serial ports COM1 and the test result from serial ports COM2 communication abnormality.
It in one embodiment, is at least two from the quantity of serial ports, as shown in figure 5, controlling main serial ports sends default report
Text presets message and carries target serial ports mark, comprising: step 502, controls main serial ports and sends default message, preset message and carry
Currently identified from the serial ports of serial ports；It controls after main serial ports sends default message further include: step 504, in default feedback duration
When the feedback message of default message inside has not been obtained, control main serial ports will currently from the serial ports of serial ports mark be changed to it is next from string
The serial ports mark of mouth, and send the message after change；It obtains feedback message that main serial ports receives and feedback message is corresponding anti-
Present duration, feedback message is to receive default message from serial ports and parse, when target serial ports identify with from the serial ports of serial ports mark
Target serial ports mark is changed the message identified for the serial ports of main serial ports, comprising: step 506, obtain main serial ports and connect by timing
The feedback message and the corresponding feedback duration of feedback message received, feedback message are that message and solution after change are received from serial ports
Target serial ports mark is changed the serial ports mark for main serial ports when target serial ports mark from the serial ports of serial ports mark with matching by analysis
Know obtained message.If main serial ports does not receive the message currently fed back from serial ports, main string in default feedback duration
Mouth sets next for target serial ports mark after default feedback duration and identifies from the serial ports of serial ports, and message is sent out
It goes, to realize main serial ports and each communication test between serial ports automatically.
In one embodiment, a kind of serial ports test method, the serial ports of communication manager is connected two-by-two, if serial ports number
Mesh is odd number, three therein can be connected, generate a message in the ascending mode of serial port, the of frame in message
One word is the serial port of current serial ports, after serial ports receives message, by the serial ports of transmission and can receive serial ports record
Get off, successively obtains the relationship between all serial ports.
After the relationship for obtaining all serial ports, will wherein serial port it is lesser be used as active transmission side (referred to as master),
Serial port is biggish to be used as recipient (referred to as slave, a master may correspond to multiple slave).Master is actively outside
Send the message of fixed frame length, the serial port (referred to as target serial port) that the first character section of message is the slave to be sent, report
Other data of literary frame are fixed.After slave receives message, to prevent multiple slave returned packet, only target strings simultaneously
When slogan is identical as the slave serial port and message is completely correct, first character section is changed to the serial port of master again by slave
It sends；When message is incorrect or target serial port is not this slave serial port, by packet loss.Master is received
After message, judge whether effectively, then the serial port that the first character section of message is set as next slave is sent into message.
If master does not receive the message that slave is sended in default time-out time, master is in default time-out time
Equally it sets target serial port to the serial port of next slave after terminating, sends simultaneously.
Setting about default time-out time, it is assumed that set T1 for the time-out time of master, for master with
For the one-to-one serial ports of slave for, slave equally can set T1 for time-out time.For there is the string of n salve
Mouth is right, it is assumed that a mater has corresponded to some slave, and message is sent to others in master by the slave in order to prevent
Time-out is mistakenly judged when salve, can set n*T1 for the time-out time of slave.
Above-mentioned serial ports test method is simple, it is only necessary to serial ports docking is got up, do not depend on any third party's tool or
Equipment can test serial ports, and it is also quite convenient to build test environment.What it is due to transmission is fixed message frame,
So the mistake of a byte can compare out, the problem of error can be very easily known.It can be according to the note of error
Record, by certain devices (such as display screen, Ethernet) of device, in real time shows the information of test, such tester
Member can hold the progress of test in real time.
It should be understood that although each step in the flow chart of Fig. 1-5 is successively shown according to the instruction of arrow,
These steps are not that the inevitable sequence according to arrow instruction successively executes.Unless expressly stating otherwise herein, these steps
Execution there is no stringent sequences to limit, these steps can execute in other order.Moreover, at least one in Fig. 1-5
Part steps may include that perhaps these sub-steps of multiple stages or stage are not necessarily in synchronization to multiple sub-steps
Completion is executed, but can be executed at different times, the execution sequence in these sub-steps or stage is also not necessarily successively
It carries out, but can be at least part of the sub-step or stage of other steps or other steps in turn or alternately
It executes.
