Embodiment
Below in conjunction with accompanying drawing, the technical characteristic above-mentioned and other to the present invention and advantage are clearly and completely described,
Obviously, described embodiment is only the section Example of the present invention, rather than whole embodiments.
Referring to Fig. 1, the multi-channel serial port method of testing that the embodiment of the present invention one provides, comprises the following steps：
S100, the serial ports type information for obtaining each serial ports to be tested, analyze and process to serial ports type information, obtain
Baud rate information, the communications protocol matched according to baud rate information selection with baud rate information；
S200, according to communications protocol selection it is default test instruct；
S300, instruction will be tested according to preset strategy to serial ports to be tested progress serial ports test；
S400, the test information for recording serial ports test result.
It should be noted that distinct device has polytype serial ports, and different types of serial ports needs are same
The communications protocol of baud rate could match docking；For example the serial ports of weak current equipment is broadly divided into three types：RS232 serial ports,
RS422 serial ports, RS485 serial ports.When serial ports to be tested is RS232 serial ports, its baud rate is 9600；So select baud rate for
9600 communications protocol matches with RS232 serial ports.
And default test instruction is mainly used in carrying out serial ports to be tested the tool of various tests for all kinds of characteristic informations
Body instructs, for example judges whether to receive and interrupt without response, if so, reception failure is then prompted, if it is not, then further determining whether to send out
Raw data overload mistake, if so, then misregistration daily record, if it is not, then judging whether to occur without bit-errors are stopped, if so, then remembering
Error log is recorded, if it is not, then judge whether to occur to receive First Input First Output mistake, if so, misregistration daily record, if it is not, then
Judge whether that verification bit-errors occur, if so, then misregistration daily record, if it is not, then terminating.
Preset strategy is the computer configured by tester according to testing requirement and different serial ports control chips
Serial ports Test Strategy, for carrying out testing classification to the serial ports of computer, including Basic function testing, pressure test, data connect
The statistics of receipts, data transmission, packet loss, packet loss etc..The preset strategy can utilize network socket interfaces.The preset strategy
Stored with document form.The file of the preset strategy has set data format.Preset strategy is that test instruction is carried out necessarily
Classification integrates, and selects corresponding preset strategy to be tested according to corresponding test instruction according to the test of different serial ports.In basis
After the default test instruction of communications protocol selection after adjustment, test can also be instructed and carry out validity test.Ensure and survey
Examination is smoothed out.
Multi-channel serial port method of testing provided by the invention, by being carried out to each serial ports type information of acquisition at analysis
Reason, the communications protocol of matching is selected according to analysis processing result；According to the default test instruction of communications protocol selection；Again will test
Instruction carries out serial ports test according to preset strategy to serial ports to be tested；And record the test information of serial ports test result.The present invention
It is simple and convenient, it not only can voluntarily select the communications protocol of matching to carry out serial ports test to the communication equipment with serial ports, and
The data that multi-channel serial port is received and sent can be tested simultaneously, data transmit-receive efficiency high, occupation mode extremely convenient use, improved
Testing efficiency, reduce tester's work load.
Further, step S300 comprises the following steps；
S310, validity test is carried out to preset strategy, serial ports to be tested is selected according to test result, while send feature
Information, characteristic information comprise at least timestamp information, attribute byte information and serial ports attribute information；
S320, according to timestamp information, attribute byte information and serial ports attribute information carry out diagnostic test, tested
Information；
Whether S330, the serial ports to be tested according to corresponding to test information judgement is each are normal.
Carry out validity test to preset strategy, including test preset strategy file it is whether complete, whether with serial ports phase
With etc..If preset strategy file is complete, match with serial ports, then preset strategy is effective, then carries out serial ports according to the preset strategy
Test；In other embodiment, tester voluntarily can also be configured to preset strategy, change the strategy of test at any time.
Diagnostic test is carried out according to timestamp information, attribute byte information and serial ports attribute information and obtains testing information
When can monitor the data that multi-channel serial port is received and sent at the same time, accurate each serial ports to be tested corresponds to data on timing node
Sending and receiving state, improve the accuracy of test, avoid the mistake caused by network fluctuation.It is and whether normal to serial ports to be tested
Judgement can be carried out by test information between serial ports and serial ports or by the test information of current serial ports with
Judgement is compared in historical test data.
After preset strategy is by validity test, full dose test can be carried out to all serial ports to be tested；Certainly
It can also first select the serial ports to be tested of a part to be tested, finally complete all serial ports to be tested and tested, specifically
Step is；Selection is polled to serial ports to be tested according to test result；At least two serial ports to be tested of selection every time, until complete
Selected into all serial ports to be tested.In the present embodiment, two or more any numbers serial ports to be tested can be selected
Carry out.
Further, the multi-channel serial port method of testing that the embodiment of the present invention one provides is further comprising the steps of；
After obtaining testing information, test information is counted and stored, test information includes the transmission word of data
At least one of packet loss of section, the reception byte of data, the packet loss byte of data and data.
It is to be adjusted according to demand to test information, such as, it is only necessary to can test serial ports be communicated, then test letter
Breath need to only include the reception byte of data.The stability of test serial ports is needed for another example, then test information just includes data
Send byte, the reception byte of data, the packet loss byte of data and the packet loss of data.The test information of statistics storage not only may be used
Seen with being directly displayed to tester, help tester to be quickly found out failure cause；Failure can also be established on this basis
Statistical description, tester carries out test and provides foundation for after, accelerates testing efficiency.
Further, the multi-channel serial port method of testing that the embodiment of the present invention one provides is further comprising the steps of；
