The wharf sweeping testing device comprises a testing end, a display end, a driving mechanism and a controller.

Fig. 1 is a schematic connection diagram of a dock broom testing apparatus according to an embodiment of the present invention. Referring to fig. 1, the dock broom test apparatus 100 of this embodiment comprises a test end 110, a display end 120, a drive mechanism 130, and a controller 140. The testing end 110 is used for carrying a to-be-tested wharf; the display end 120 is used for generating and displaying a bar code; the driving mechanism 130 has a mold (not shown) for receiving the display end 120 or the testing end 110; the controller 140 is used for controlling the testing terminal 110, the display terminal 120 and the driving mechanism 130, wherein the controller 140 controls the parameters of the terminal-scanning test of the terminal-scanning to be tested through the testing terminal 110, and the controller 140 controls the movement of the driving mechanism 130 and the bar code to be generated and displayed by the display terminal 120 according to the test content.

In the embodiment shown in fig. 1, if the display terminal 120 is placed on the mold of the driving mechanism 130, the driving mechanism 130 can drive the display terminal 120 to move under the control of the controller 140, and at this time, the position of the testing terminal 110 is fixed; if the testing terminal 110 is placed on the mold of the driving mechanism 130, the driving mechanism 130 can drive the testing terminal 110 to move under the control of the controller 140, and at this time, the position of the display terminal 120 is fixed.

Referring to fig. 1, connection lines are used to show connection relationships of the respective elements, but the connection lines are not used to limit connection between the respective elements by a wired manner. The controller 140 is connected to the display terminal 120, the test terminal 110 and the driving mechanism 130.

In some embodiments, one or any of the controller 140, the test terminal 110, the display terminal 120, and the drive mechanism 130 are connected to the same wireless network. In the embodiment shown in fig. 1, the controller 140, the testing terminal 110, the display terminal 120 and the driving mechanism 130 are all connected to the same router 150, that is, the controller 140, the testing terminal 110, the display terminal 120 and the driving mechanism 130 are in the same wireless network. The driving mechanism 130 may receive an instruction from the controller 140 through the wireless network, so as to control the movement of the mold according to the instruction, and further drive the movement of the display end 120 or the testing end 110.

In some embodiments, the test content includes one or any combination of depth of field test, gray scale test, motion tolerance, fixed speed, color bar code, and dirty bar code, and the test required can be customized according to actual requirements. The barcode to be generated by the display 120 is different for different test contents, for example, the content and the size of the barcode (e.g., a 15mil QR code) may be different.

Illustratively, when the test content is a color barcode, the controller 140 controls the display terminal 120 to generate the color barcode. The method of how the display terminal 120 generates the color bar code is not limited by the present invention. A plurality of color barcodes for performing a color barcode test may be stored in the controller 140 in advance. When the color bar code test is carried out, a certain number of color bar codes can be selected to carry out the test in sequence according to a preset program. When the test content is a dirty barcode, the display terminal 120 generates the dirty barcode. In practical situations, the contaminated bar codes can be in various contaminated situations, for example, the positions, sizes, shapes, and the like of contaminated parts can be varied, and the controller 140 can preset various contaminated bar codes according to needs and sequentially display the needed contaminated bar codes according to programs.

Similarly, the driving mechanism 130 moves in different manners for different test contents. For example, when the test content is the depth of field test, the controller 140 controls the driving mechanism 130 to move according to the requirements of the depth of field test. For example, when the display end 120 is mounted on the mold of the driving mechanism 130, the display end 120 is first brought closer to the testing end 110 for close-range testing, the distance is gradually increased from an initial position, and the controller 140 controls the scanning head to be tested on the testing end 110 to perform one code scanning each time the position is changed, and records the code scanning result. In the moving process of the display end 120, the distance when the code scanning of the wharf to be detected succeeds for the first time is the close range, and when the distance is increased to a certain degree, the code scanning of the wharf to be detected fails, the distance is recorded as the long range. The depth of view test content is merely an example and is not intended to limit the specific content of the actual depth of view test.

In some embodiments, the controller 140 is further configured to send a first instruction to the driving mechanism 130, where the first instruction includes an instruction to control a movement trajectory and/or a movement speed of the driving mechanism 130. It will be appreciated that the first instruction is associated with test content. The movement trajectory is an arbitrary route in a three-dimensional space.

In some embodiments, the controller 140 is further configured to send a second instruction to the display end 120. The second instruction includes displaying one or any combination of the size, type, color, and grayscale of the barcode. It will be appreciated that the second instruction is associated with test content.

According to the embodiments, when the wharf broom to be tested is tested, the controller 140 sends a first instruction to the driving mechanism 130 to enable the driving mechanism 130 to move according to the test content, so that the test process has good controllability; the controller 140 sends a second instruction containing different contents to the display terminal 120 to change the contents of the bar code displayed by the display terminal 120, so that the bar code does not need to be replaced manually, and the testing efficiency is improved.

In some embodiments, the controller 140 is further configured to record the status of the barcode generated and displayed by the display terminal 120, where the status includes one or any combination of success in generating the barcode, failure in generating the barcode, and timeout in generating the barcode. When the test is performed, a specific barcode needs to be generated and displayed by the display end 120 according to the test content, however, in some cases, the barcode finally generated and displayed by the display end 120 may be different from the barcode scheduled to be displayed. Thus, these embodiments provide a verification function for displayed barcodes. According to the state of the recorded bar code, the success, failure or overtime of the bar code generation can be determined. Therefore, when the bar code generation fails, the fault can be timely eliminated, and the long-time stop of the code scanning test caused by the failure of the bar code generation is avoided.

In some embodiments, the display terminal 120 returns the result of generating the barcode according to the first instruction to the controller 140, so that the controller 140 obtains the result of generating the barcode, thereby calculating the status of the barcode.

The present invention does not limit the type of the barcode displayed on the display terminal 120, and the barcode may include a one-dimensional barcode, a two-dimensional barcode, a multi-dimensional barcode, and the like. In particular, for example, the following types of barcodes: CODE25_ INTERLEAVED, CODE39, CODE25_ INDUSTRY, CODE39_ EXTENDED, CODE93, CODE 128, EAN, UPC _ A, UPC _ E, QR, PDF417, DATAMATRIX, AZT EC, CHANNEL _ CODE, CODBAR, CODE25_ INDUSTRY, CODE25_ INTERL EAVED, CODE _11, CODE25_ MATRIX, CODE25_ IATA, CODE25_ DATALO GIITC, ITF14, CODE39, CODE39_ EXTENDED, CODE93, DOD _ LOGMRS, CODE _128, NVE18, EAN, MSI _ PLSEY, TELECHEN _ NUMERIC, TELEPEN _ NUMERIC C, UPC _ 5_ E, CODABLOCK _ E, CODABLOCK, CODE E, CODABLOCK, PDF417, POSE 417, POST _ ADD _ DB, POSI _ ADD _ DSD _ PLEAD, POSI _ PLEAD, AZT _ ADC, POSS _ ADD _ ADC, POSS _ ADC _ E, CODABLOCK _ ADC, POSS _ ADC _ E, CODABLOCK _ ADC _ 685 _ E, CODABLOCK _ SER _ E, CODABLOCK, CODE _ SER _ S _ SER _ SERC _ S _ CON _ 4, CODE _ CON _ S _ 4, POSS _ CON _ 4, CODE _ CON _ 4, CODE _ CON _ 4, CODE _ CON _ 4, CODE _ COND _ CON _ 4, CODE _ COND _ CON _ COND _ CON _ 4, COND _ CON _ 4, CON _ 4, COND _ CON _ COND _ 4, CODE _ CON _ COND _, CODE _128_ HIBC, DATAMATRIX _ HIBC, PDF417_ MICRO _ HIBC, QR _ HIBC, PHARMA _ tworrac K, PZN, USPS _ IMPB.

In some embodiments, the controller 140 includes a computer (PC), tablet, or like terminal.

In some embodiments, the controller 140 is further configured to send a third instruction to the testing end 110, where the third instruction includes the dock-sweeping test parameter and the test result parameter. The wharf scanning test parameters comprise a switching command and a code scanning frequency of the wharf to be tested, and the test result parameters comprise timeout time. The controller 140 sends a third command to control the opening and closing of the wharf sweeping head without human intervention. The frequency of the code sweep and the timeout may also be varied by the controller 140. For example, the code-sweeping frequency may be set to 20 milliseconds by the controller 140, i.e., once every 20 ms; the timeout time is set to 2 seconds, namely, if the code scanning result is not generated after 2 seconds of code scanning, the code scanning times out.

In some embodiments, the controller 140 is further configured to determine a test result of the current code scanning test according to the test result parameter, where the test result includes one or any combination of test success, test failure, and timeout failure. For example, the controller 140 sets the timeout time to 2 seconds, and when the code scanning time of the test terminal 110 exceeds 2 seconds, the code scanning result cannot be obtained, the controller 140 determines that the code scanning test result is code scanning timeout; if the correct code scanning result is obtained, the controller 140 determines that the code scanning test is successful, and then moves the driving mechanism 130 to perform the next test. If the code scanning fails, the code scanning is carried out again until the failure times reach the preset number or the code scanning is overtime. For the above test results, the controller 140 may store the test results in a digital format, such as xls, txt format, to facilitate the sharing, backup and transfer of the subsequent test results. Meanwhile, the step of manually recording the test result is omitted, and the test efficiency is improved.

Fig. 2 is a schematic structural framework diagram of the dock broom testing apparatus according to an embodiment of the present invention. Referring to fig. 1 and 2, in the embodiment shown in fig. 2, the testing end 110 of the testing apparatus 100 is embodied as a code scanning testing end 210, the display end 110 is embodied as a code display end 220, the driving mechanism 130 is embodied as a robot arm 230, and the controller 140 corresponds to the controller 240 in fig. 2. Since FIG. 2 is an embodiment of the embodiment shown in FIG. 1, like elements may be referred to by different numbers, such as controller 140 and controller 240, referring to controller 140 of the frame-based testing device 100 and controller 240 of the embodied testing device 200, respectively, which belong to different designations of like elements.

Referring to fig. 2, in the test apparatus 200, a scan head to be tested is mounted on a scan test terminal 210. The code scanning test end 210 can be used for carrying various types of code scanning heads and has wide universality. The barcode is generated and displayed at the barcode display end 220.

In some embodiments, the display end includes a display screen. In the embodiment shown in fig. 2, the barcode display 120 may be various types of displays, such as a liquid crystal display, an ink display, an LED display, etc.

A mold for receiving the barcode display end 220 is provided on the robot arm 230. When testing, the bar code display end 220 is placed on the mold of the robot arm 230, so that the robot arm 230 can drive the bar code display end 220 to move.

As shown in FIG. 2, in this embodiment, the code scanner 210, the code display 220, the robotic arm 230, and the controller 240 are all disposed on a table 250. The working platform 250 may be a table top with a certain height from the ground, or may be the ground. In other embodiments of the present invention, the above-mentioned devices may be placed according to actual test requirements, and are not limited to the situation in this embodiment.

Referring to fig. 3, four execution bodies in the embodiment shown in fig. 2 are included in the timing diagram: a bar code display end 220, a controller 240, a code scanning test end 210, and a robotic arm 230. And the long bar below each execution main body represents a time progress bar from top to bottom, and the end points of the aligned progress bars represent that the task nodes execute actions at the same time.

Referring to fig. 3, for example, when the controller 240 is a PC, the PC end is directly connected to the robot arm 230 through a development manual of the robot arm 230 in an IP address manner, and sends a first instruction to the robot arm 230 through the link manner, the PC end is connected to the barcode scanning test end 210 and the barcode display end 220 in a Socket communication manner, and sends a second instruction and a third instruction to the barcode display end 220 and the barcode scanning test end 210 respectively through the Socket communication manner, the barcode display end 220 returns the state of the generated barcode to the controller 240, and the barcode scanning test end 210 returns the test result parameters to the controller 240. The controller 240 determines the test result of the current code scanning test according to the test result parameters, and if the test result is successful, the mechanical arm 230 is moved to perform the next code scanning test; if the test fails, the code is scanned again until the test is successful or the time is out.

For example, in the close-range test, the result of code scanning failure is obtained from the closest point, and the test is continued until the code scanning is successful. In the long-range test, the code scanning test result is always successful at the beginning, and the code scanning fails when the farthest point is reached, so that the judgment is needed again.

In some embodiments, each instruction may include a corresponding command sequence number, and each returned result, such as the status of the barcode and the test results, may also include a corresponding sequence number to facilitate execution of the program.

In some embodiments, the maximum transmission value of Socket communication data may be referred to according to the length of the character string of the displayed barcode and the length of the returned test result. For example, the present embodiment sets the maximum transmission value of Socket communication data to 4 Kb.

In some other embodiments of the present invention, the controller 240 may also be connected to the robot arm 230 via serial port or bluetooth to send the first command to the robot arm 230.

The above description is not intended to limit the connection manner between the test terminal, the display terminal, the driving mechanism, and the controller, and the specific connection manner may be various.

The testing device of the utility model combines the controller, the testing end, the display end and the driving mechanism into a unified automatic testing device, and sends instructions to the testing end, the display end and the driving mechanism through the controller to carry out various tests, thereby being capable of automatically completing the test of the wharf sweeping and improving the testing efficiency. And the test result is exported in a digital format, so that the test result is convenient to share, backup and transmit.

In the embodiment shown in fig. 2, the position of the code scanning testing end 210 can be fixed, and the robot arm 230 only drives the code display end 220 to move to test the code scanning head to be tested. In other embodiments of the utility model, the display end is fixed and the test end is driven by the driving mechanism for testing.

Thus, the robot 430 moves the code scanning test terminal 420 according to the first command sent by the controller 440, and the moving manner is related to the test contents. It is understood that, for the same test content, the first instructions sent by the controller in the embodiments shown in fig. 2 and fig. 4 may be the same or different, and need to be determined according to the specific test content. For example, in the depth of field test, in the embodiment shown in fig. 2, the robot arm 230 drives the barcode display end 240 to approach the barcode scanning test end 210 first, and then gradually move away from the barcode scanning test end; in the embodiment shown in FIG. 4, the robot 430 drives the code scan testing end 410 to approach the code scan testing end 410 first and then to move away from the code scan testing end gradually, in this example, the moving manner of the robot may be the same, and the first command is the same.
