The method also comprises the following steps that C, a PC machine sends a command in an appointed directory to the vehicle-mounted equipment, and the vehicle-mounted equipment receives and executes the command; D, the PC machine sends a command for operating a testing script in the appointed directory to the vehicle-mounted equipment, and the vehicle-mounted equipment receives and executes the command; and E, the PC machine reads information acquired in the step D line by line, compares error information, and if a situation that a copyfile and a testfile are inconsistent in size or content, the type and time of errors are stored. According to the invention, the copying speed and copying satisfaction situation of the vehicle-mounted equipment at different copying intensities are synthetically considered, so that the reliability of copying operations of the vehicle-mounted USB equipment at different copying intensities can be reflected, and therefore, the error rate is reduced, the reliability of test results is improved, the type of errors can be accurately defined, and then the time for solving problems is shortened.
Description
Technical field
The present invention be more particularly directed to a kind of vehicle-mounted USB device performance test methods.
Background technology
Often adopt USB device as data transmission interface in field of track traffic mobile unit, for guaranteeing that it can meet the requirement of complicated severe on-board running environment, USB device must can steady operation, all kinds of problems of the influential system job stability such as do not occur USB device nonrecognition, data download complete, USB device copy procedure fault, therefore, need to carry out fully and test for a long time the reliability of its work before USB device comes into operation.
Existing vehicle-mounted USB device performance test methods can only carry out basic functional test to USB device, only whether test USB device can identify USB flash disk, namely test USB device whether can power on, load, and whether the performance reliability index can not testing USB device meets the demands.Performance reliability index weighs the major criterion that can USB device meet the severe industry park plan environment of locomotive, comprise copying speed, copy meets and copies intensity, file read-write speed when wherein copying speed refers to copy, copy to meet and refer to that the size of copied files and content are consistent with test file, copy intensity refers to the number of times of copy function.
Summary of the invention
When using existing vehicle-mounted USB device performance test methods to test vehicle-mounted USB device, whether the performance reliability index can not testing USB device meets the demands, and simultaneously test result may exist and is difficult to Wrong localization reason.The object of the invention is to, for above-mentioned the deficiencies in the prior art, provide a kind of vehicle-mounted USB device performance test methods improved.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of vehicle-mounted USB device performance test methods, comprises step:
A. PC send to USB device to power on instruction to mobile unit, mobile unit receives instruction and also performs, and execution result is fed back to PC by mobile unit simultaneously; If power on unsuccessfully, the instruction that PC sends to USB device to power on again is to mobile unit, and mobile unit again receives instruction and performs, and execution result is fed back to PC by mobile unit again simultaneously; If reach the number of times upper limit that powers on of setting, USB device can not successfully power on, and stops powering on to USB device and reporting an error;
The instruction that B.PC machine sends to USB device to load is to mobile unit, and mobile unit receives instruction and performs, and execution result is fed back to PC by mobile unit simultaneously; If load unsuccessfully, the instruction that PC sends to USB device to load again is to mobile unit, and mobile unit again receives instruction and performs, and execution result is fed back to PC by mobile unit again simultaneously; If reach the loading number of times upper limit of setting, USB device can not successfully load, and stops loading to USB device and reporting an error;
Also comprise step:
The transmission of C.PC machine enters the instruction of assigned catalogue to mobile unit, and mobile unit receives instruction and also performs;
D.PC machine sends the instruction of the test script under operation assigned catalogue to mobile unit, and mobile unit receives instruction and also performs; Described test script is used for arranging number of copy operations, arrange initial time that the size of test file and content, reading copy at every turn and the mistiming that end time, calculating copy at every turn, the content of the size reading copied files, contrast copied files and test file; In the process of mobile unit testing results script, if USB device occurs reading or writing protection, then report an error;
The information that E.PC machine collects in read step D line by line, carries out the comparison of error message simultaneously, if there is the size of copied files and test file or content inconsistent, storage errors type and makeing mistakes the time.
Further, when carrying out the comparison of error message in step e, if copied files is with the in the same size of test file and content is consistent, PC calculates, stores and export copying speed information.
Because USB device carries out high strength, repeatedly copy function for a long time, therefore error message and copying speed information can reflect the performance of vehicle-mounted USB device on the whole.
Further, in step D while testing results script, PC sends and checks that the instruction of mobile unit CPU usage and/or memory usage is to mobile unit, and mobile unit receives instruction and performs, and execution result is fed back to PC by mobile unit simultaneously; PC reads line by line, store and export the total CPU usage of the mobile unit that collects and/or memory usage information, screens simultaneously and exports CPU usage and/or the memory usage information of vehicle-mounted USB device performance test.
When utilizing existing vehicle-mounted USB device performance test methods to test, owing to not considering mobile unit CPU usage and memory usage, for because of CPU usage or the too high and situation of the USB flash disk cisco unity malfunction caused of memory usage, may take for is that the performance of vehicle-mounted USB device own can not meet the demands, thus causes test result inaccurate.
Consider total CPU usage of output and/or memory usage information, the CPU usage of vehicle-mounted USB device performance test and/or memory usage information, can analyze further and judge whether the performance of vehicle-mounted USB device own meets the demands, whether vehicle-mounted USB device performance is caused to reduce because mobile unit whole system load is excessive, thus reduce positioning problems error rate, improve the reliability of test result.
Further, also comprise statistics in step e and to make mistakes number of times, number of times of makeing mistakes obtains error rate divided by number of copy operations.
Error rate can reflect the reliability of vehicle-mounted USB device copy work under different copy intensity.
Further, also step is comprised:
F.PC machine sends the instruction of load-off of USB apparatus to mobile unit, and mobile unit receives instruction and performs;
G.PC machine sends to the instruction of USB device power-off to mobile unit, and mobile unit receives instruction and performs, and execution result is fed back to PC by mobile unit simultaneously; If power-off failure, PC sends to the instruction of USB device power-off to mobile unit again, and mobile unit again receives instruction and performs, and execution result is fed back to PC by mobile unit again simultaneously; If reach the power-off number of times upper limit of setting, USB device can not successful power-off, stops to USB device power-off and reports an error.
Compare with prior art, the present invention considers the copying speed of vehicle-mounted USB device under different copy intensity according to performance reliability index comprehensive and copy meets situation, the reliability of vehicle-mounted USB device copy work under different copy intensity can be reflected, by reading mobile unit CPU usage and memory usage, reduce error rate, improve the reliability of test result, simultaneously can accurate Wrong localization type, developer can be suited the remedy to the case, shorten the time of dealing with problems.
