The most key concept of the invention is as follows: the code scanning time performance is measured in a mode that a testing machine is connected and interacted with code scanning equipment to be tested, more than 1000 times of cycle testing are set, and random sleep time is added at each cycle interval, so that the minimum value of a test result is infinitely close to a true value.
Referring to fig. 1, a method for testing code scanning time of a code scanning device includes the following steps:
s1: entering a continuous code scanning mode by code scanning equipment to be detected; when the machine to be tested enters a continuous code scanning mode, the image collecting and decoding process is automatically and circularly acquired;
s2: the test machine displays the two-dimensional code image;

s6: when the test machine receives feedback information sent by the code scanning equipment to be tested, the test machine records a time point as a time point 2;
s7: the testing machine clears the displayed two-dimensional code image;
s8: the testing machine sleeps for 0-T milliseconds; the value range of the T is between 10 and 200;
s9: loop S2-S8; the number of the circulation is more than 1000;
s10: recording time point 2-time point 1 values in each cycle; the minimum value obtained is the measured code scanning time.
The test principle of the method for testing the performance of the code scanning device is described as follows: the tester is equipment with a display function, an operating system and an external interface, and comprises ARM, DSP, PC, a mobile phone, common PDA equipment and the like; fixing the tester at a position, and communicating by using an RS232 interface through a USB data line;
firstly, a to-be-detected code scanning device is set to be in a continuous code scanning mode, in the state, the to-be-detected code scanning device automatically and circularly acquires and decodes images, the to-be-detected code scanning device and a testing machine are fixed on a frame, and a camera of the to-be-detected code scanning device aligns with a display screen of the testing machine; when the test is started, the display screen of the test machine refreshes and displays the two-dimensional code image, the time point after the display is finished is recorded as a time point 1 which is equivalent to the time when the code scanning equipment to be tested starts to scan the code, and the code scanning equipment to be tested collects and decodes the two-dimensional code image displayed by the test machine; when the code scanning equipment to be tested finishes decoding the two-dimensional code image displayed by the testing machine, the code scanning equipment to be tested sends feedback information to the testing machine; when the test machine receives feedback information sent by the code scanning equipment to be tested, the test machine records a time point as a time point 2; the time equivalent to the time point 2-the time point 1 is the code scanning time of the code scanning equipment to be detected; the time point generally has errors, because the optimal situation is that when the tester records the time point 1, the code scanning equipment to be tested just enters the acquisition state of successfully decoding the image, but because the code scanning process time is very short, the ideal situation is difficult to realize; when a testing machine starts to display a two-dimensional code image, the running time point of a program of code scanning equipment to be tested may be the starting point of the acquisition state of an image which just enters a non-successfully-decodable state (the image in a data buffer area is a non-two-dimensional code image source), the time point of time point 1 may be the state of any one moment in any period in the cyclic code scanning process of the code scanning equipment to be tested, and the time point of time point 1 may also be the processing decoding state of the image which is not successfully decodable, so that under the general condition, the time from time point 2 to time point 1 is longer than the actual code scanning time of the code scanning equipment to be tested;
because the code scanning time of the code scanning equipment is very short, the time point of refreshing the two-dimensional code by the testing machine cannot accurately correspond to the acquisition state of the image which can be successfully decoded, only through continuous and repeated simulation approximation, the minimum measurement time is continuously calculated along with the increase of the simulation running times, namely the optimum approaching code scanning time, and the confidence coefficient that the obtained minimum measurement time is the reliable code scanning time of the code scanning equipment is higher along with the increase of the simulation running times;
therefore, after the test machine receives the signal after the scanning is successful, the displayed two-dimensional code image can be cleared, after the short-time random dormancy is carried out for 0-T milliseconds, the screen refreshes and displays a new two-dimensional code image, and the code scanning test process is continuously and repeatedly circulated; the random dormancy 0-T milliseconds are set according to the time period of the code scanning equipment to be tested, T is generally 10-200 ms, the value of T is the code scanning period of the code scanning equipment to be tested, in the actual test environment, in the face of common code scanning equipment in the market, the current code scanning performance is generally close, the fluctuation of the main comparison time range is in the level of dozens of milliseconds, therefore, generally T is in the value range, and the code scanning performance test of most of the code scanning equipment can be ensured by taking 5ms as the adjustment step length; because the T values of different to-be-detected code scanning devices are possibly different (for example, the HONEYWELL MS9540 laser bar code scanning gun T is about 14MS, the Motorola symbol ls2208ap bar code scanner T is about 32MS for the 10MS New continent NLS-HR1030 bar code scanning gun T, and the Motorola Clarigo C11 one-dimensional scanning gun T is about 100 MS), the value of the T is required to be adjusted according to the actual situation, so that the situation that a tester is periodically started to display a two-dimensional code, and the to-be-detected code scanning devices repeatedly display the same value in the follow-up process after the code scanning time is firstly measured by the to-be-detected code scanning devices is avoided; after the random dormancy, the host computer can be ensured to start displaying the two-dimensional code, and the code scanning equipment program to be tested is in a random state.
The cycle times are generally more than 1000-10000 times, enough times are the minimum value which is guaranteed to continuously approach the code scanning time of measurement, and after the enough times are simulated and run, more times are only slightly improved without necessity, so the times are generally more than 1000 times.
According to the law of large numbers, the minimum value of the obtained time point 2-time point 1 values is continuously close to the true value of the code scanning time through multiple times of cyclic measurement, and therefore the relatively accurate code scanning time is measured.
In the method for testing the performance of the scanning equipment, the time is automatically measured in a circulating manner, and the scanning equipment is randomly dormant for a period of time before a tester refreshes and displays a two-dimensional code, so that the code scanning starting time point of each circulating measurement corresponds to the random state of the scanning equipment to be tested, therefore, the result of each measurement is ensured to be different, and the measured minimum value approaches to the true value of the code scanning time infinitely along with the increase of the measurement times; because the whole circulation automatic measurement process does not need manual participation, the automation of measurement is realized; compared with the traditional timing method by auxiliary equipment such as a timing watch and the like, the timing result is more accurate; compared with the method for testing the code scanning time based on respective platform programs, the code scanning device to be tested does not need to be additionally provided with a test function on the code scanning program, so that the method is not influenced by the platform performance and the program resource distribution condition, is convenient to operate, and is small in implementation workload.
In the method for testing performance of code scanning device, after S7, the method further includes:
the screen clearing state of the tester is kept for 1-3 seconds.
The screen of the testing machine is cleared for 1-3 seconds, so that the slave machine can only successfully decode one frame of image frame containing the two-dimensional code at most in one code scanning period, and the code scanning time performance of the code scanning equipment is measured and counted more reliably; the screen clearing time is 1 second, so that the code scanning equipment to be tested can effectively acquire two-dimensional codes in an image acquisition state, and the condition that a plurality of two-dimensional code image data which can be successfully decoded exist in a buffer area of the code scanning equipment to be tested is avoided, so that the condition that a host continuously receives a plurality of same signals due to the fact that the decoding time of misdetection is 0 due to the fact that the signals which are successfully decoded are immediately received once the test machine is started is avoided.
In the method for testing the performance of the code scanning equipment, the screen clearing state of the testing machine is kept for 1 second.
