In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be understood that the structures, ratios, sizes, and the like shown in the drawings are only used for matching the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the practical limit conditions of the present application, so that the modifications of the structures, the changes of the ratio relationships, or the adjustment of the sizes, do not have the technical essence, and the modifications, the changes of the ratio relationships, or the adjustment of the sizes, are all within the scope of the technical contents disclosed in the present application without affecting the efficacy and the achievable purpose of the present application.
Embodiments of the present invention are written in a progressive manner.
The embodiment discloses a method for testing USB expansion equipment, which comprises the following steps:
s1, reading preset data on storage equipment;
s2, sending preset data to receiving equipment through N expansion interfaces of the USB expansion equipment;
s3, acquiring N copy data received by the receiving equipment;
s4, carrying out consistency verification on the N copied data;
s5, if the N copied data are consistent, outputting test information;
s6, if the copied data are different, outputting early warning information;
s7, restarting the USB expansion equipment;
and circulating the steps according to preset times.
The method for testing the USB expansion device provided in this embodiment stores preset data in a storage device in advance, sends the preset data to a receiving device through the USB expansion device to be tested, then performs consistency verification on the copied data received by each expansion interface, outputs corresponding information according to a verification result, restarts the interface, and performs a cycle test for a preset number of times. Whether the data copy of the USB expansion equipment is correct and effective is judged automatically, and the method is simple and effective.
Preferably, before reading the preset data on the storage device, the method further comprises:
s10, initializing USB expansion equipment;
and S11, connecting the storage equipment with the receiving equipment through the USB expansion equipment.
Before the preset data is read, in order to avoid the influence of some unknown factors of the USB expansion equipment, the USB expansion equipment is initialized, the influence of the unknown factors on the test is clear, and then the USB expansion equipment is used for directly connecting the storage equipment with the receiving equipment, so that the reliability of the test is guaranteed.
Preferably, in the mth cycle, reading the preset data on the storage device specifically includes:
and reading the M +1 th preset data on the storage device as the current preset data.
When the Mth cycle returns to the initial step, the M +1 th preset data is read, namely the preset data is replaced, so that the meaningless operation of the subsequent step caused by the error of the previous preset data can be avoided.
Preferably, the outputting of the early warning information specifically includes:
if one of the copied data is different from the other more than two copied data, recording one internal detection early warning, and carrying out probability statistics according to the internal detection early warning to obtain a probability statistical result;
and if the probability statistical result is greater than the probability statistical preset value, outputting early warning information.
For the situation that the copy data of one time are different due to external factors and the USB expansion device normally operates the next time, early warning operation does not need to be executed due to occasional changes, so that the copy data of one time are different and recorded as internal detection early warning, probability statistics is carried out according to the frequency of the internal detection early warning, and when the probability statistics result reaches a certain critical value, the situation that the internal detection early warning is not caused by the accidental external factors but the USB expansion device has problems is shown.
It can be understood that there are many statistical ways similar to the above, and the probability of sending out the internal detection early warning can be counted to judge whether the probability exceeds a certain preset value: whether the number of times of sending the internal detection early warning in the preset time exceeds a certain preset value can be judged: whether a preset number of internal detection early warnings are continuously received or not can be judged, and the specific implementation mode is not limited in a relevant mode, so long as false alarms caused by one-sidedness of a single early warning mode can be avoided.
Preferably, after the outputting the warning information, the method further includes:
recording an expansion interface corresponding to the copy data with the difference as a priority interface;
the consistency verification of the N pieces of copy data is specifically to compare the consistency of the copy data corresponding to the priority interface with the copy data of other expansion interfaces;
if the two are consistent, consistency comparison is continuously carried out on other copied data;
if the two are different, alarm information is output and the test is finished.
And when the consistency is verified, the priority interface is used as a first compared object to be compared with other expansion interfaces to compare the consistency of the copied data, and if the consistency is consistent, the other interfaces are continuously compared. Therefore, the suspicious interface can be tested again quickly in a targeted manner, and the processing time required by subsequent cycle test is reduced.
Preferably, the reading of the M +1 th preset data on the storage device is specifically as follows:
judging the type of the M-th cycle output information;
if the output information is the test information, reading the M +1 th preset data on the storage equipment as the current preset data;
and if the output information is early warning information, reading Mth preset data on the storage device as the current preset data.
Namely, if the last test result is normal, the last preset data is still adopted as the preset data of this time, and if the last test result is early warning, the next preset data is adopted as the preset data of this time, so that detection misjudgment caused by data errors can be avoided.
