Detailed description of the invention
A kind of quick judgement serial ports of the present invention is connective and stability method is described in detail below below.
A kind of quick judgement serial ports is connective and the method for stability, the connection between general simple Serial Port Line, can fast and effeciently judge connectedness and the stability of serial ports cable, the scene of solving cannot judge Serial Port Line whether can thorny problem. In ease for use, software and notebook computer can realize connectedness and the stability test of Serial Port Line very easily to utilize one. Automatic continuous for the pseudo noise code of standard, either directly through rule, is sent to opposite end by Serial Port Line, and the counting and formula by science calculates, and evaluates and tests out the extent of stability of Serial Port Line by the method; Including conventional operating system, multiple different types of Serial Port Line equipment, ComMaster software;
Operating system end installs serial port drive, RS232 serial ports is connected to computer end, the connectedness of serial ports can be carried out basic test by the basic parameter having configured serial ports, serial ports two ends are connected two different computers, respectively as flow receiving terminal and originating end, checked the quality of Serial Port Transmission by the standard pseudo noise code automatically sent, Serial Port Transmission quality also can be showed by the bit error rate very intuitively.
Conventional operating system is general windows operating system, Linux system, windows operating system include windowsXP, win7, win8, windowsserver2003,2008; Linux system includes RedHat, Centos, Ubuntu.
Some different types of Serial Port Line equipment such as USB turn Serial Port Line, RJ45 RS 232, it is possible to support that major part RS232 Serial Port Line carries out connectedness and stability test under different application scene.
ComMaster software kit is containing AccessPort, serial ports stability test, and AccessPort can be monopolized serial ports and send/receive data, debugs the signal procedure of known various serial ports parameter; Serial ports test module can pass through to send/and serial equipment/circuit carries out error code testing, and directly calculates the bit error rate by reception standard pseudo noise code.
In order to ensure the stability in test serial ports process, this method also sets the mechanism of a kind of unidirectional use serial ports, if namely serial ports is just at transmitting data stream, the work now performing AccessPort or serial ports stability test again is to be allowed for, and also ensure that the accuracy of test result from the side.
In order to ensure readability and the intuitive of transmitting terminal and receiving terminal delivery flow rate size in Serial Port Line test process, this method is outside the dynamic real-time graph of generation shows, figure shows transmitting-receiving flow per second, and is capable of automatically generating the function of test result.
In order to the steadiness of Serial Port Line can be seen more intuitively, according to the sole criterion bit error rate (bit error rate=(n1-n2)/n1*100%) weighing Serial Port Line stability. The bit error rate (BER:biterror) is to weigh the index of data radio station data data at the appointed time transmission accuracy. The bit error rate of usual data radio station should BER��10E-6. One of performance indications of digital data transmission. Representing the probability that code element is erroneously received, the code element number that goes wrong in namely received code element accounts for the ratio transmitting total code element number. The bit error rate is used to weigh the frequency that error code occurs.
In order to test the stability of Serial Port Line more accurately, process provides the 2^15-1 of standard, 2^11-1,2^9-1 pseudo noise code and the artificial code of 16bit, error code can also be inserted by automatic/hand simultaneously, be used for testing the detection accuracy of Serial Port Line verification strategy after running into error code or inspection software.
