Figure 1 is a schematic diagram of the test system of the present invention. As shown in the figure, the test system 100 includes a test platform 102, a test object 104, and peripheral devices 110, 112, and 114. The DUT 104 is coupled to the test platform 102 and has input/output ports 106 and 108. The invention does not limit the types of the input/output ports 106 and 108. In a possible embodiment, the input/output ports 106 and 108 are the same type of input/output ports, such as USB ports. In another embodiment, the type of the input/output port 106 is different from the type of the input/output port 108. For example, the input/output port 106 is a USB port, and the input/output port 108 is a shadow Like input ports, such as Video Graphics Array (VGA) port, DisplayPort (DP), High Definition Multimedia Interface (HDMI) or Digital Visual Interface (DVI) port . In other embodiments, the DUT 104 has fewer or more input/output ports. In addition, the present invention does not limit the type of the object 104 to be tested. In a possible embodiment, the test object 104 is a motherboard.

The peripheral devices 110, 112 and 114 are coupled to the test platform 102. The present invention does not limit the types of peripheral devices 110, 112, and 114. In one possible embodiment, the peripheral devices 110, 112, and 114 are all USB peripheral devices. The present invention does not limit the number of peripheral devices of the test system 100. In other embodiments, the test system 100 has fewer or more peripheral devices. For example, at least one of the peripheral devices 110, 112, and 114 may be a dongle, a flash disk, an gaming keyboard, an gaming mouse, a hard disk, and a Optical disc drive, a USB 2.0 hub, a USB 3.0 hub, a wireless camera lens, a wired camera lens, a network card (LAN card), a scanner (scanner), a stereo, a speaker, a blue Bud device, a galvanometer or a charger.

The test platform 102 is used to test the compatibility between the interface of the DUT 104 and different peripheral devices. In this embodiment, the test platform 102 is coupled between the object under test 104 and the peripheral devices 110, 112, and 114, and according to the control signal SC, connects one of the input/output ports 106 and 108 to the peripheral devices 110, 112 And 114 are electrically connected together. In one possible embodiment, the test platform 102 electrically connects the input/output ports 106 to the edge devices 110, 112, and 114 in sequence, and then connects the input/output ports 108 to the edge devices 110, 112, and 114 in sequence.

In other embodiments, the test system 100 further includes a control machine 116. Whenever the test platform 102 is electrically connected to a specific input/output port and a specific peripheral device, the object under test 104 communicates with the specific peripheral device through the specific input/output port to generate a communication result. In a possible embodiment, when the object 104 to be tested performs different actions according to different peripheral devices. For example, when the peripheral device is a charger, the DUT 104 charges a battery. In this example, the DUT 104 uses the charging current as a communication result. In other embodiments, the peripheral device is a speaker. When the speaker plays music, the DUT 104 may use a microphone to pick up the played audio file, and convert the audio file into text for recognition. In this example, the test object 104 uses the recognition result as a communication result.

The control machine 116 generates different test results according to the different communication results generated by the test object 104. According to the test results, the tester can know whether the DUT 104 is compatible with different peripheral devices. For example, suppose that the peripheral device 110 is a storage device (such as a flash drive), the peripheral device 112 is a gaming keyboard, and the peripheral device 114 is a camera lens. When the test platform 102 is electrically connected to the input/output port 106 and the peripheral device 110 according to the control signal SC, the DUT 104 may write a specific data to the peripheral device 110, and then read the data of a specific address, using To generate a first read data. In this example, the test object 104 uses the first read data as a communication result CR1. The control machine 116 compares the specific data with the first read data according to the communication result CR1 to generate a first test result. When the test platform 102 is electrically connected to the input/output port 106 and the peripheral device 112 according to the control signal SC, the DUT 104 may read the vendor identification number (VID) and the product identification code ( product identification number; PID), used to generate a first detection result. In this example, The test object 104 uses the first detection result as a communication result CR2. The control machine 116 uses the communication result CR2 as a second test result. When the test platform 102 is electrically connected to the input/output port 106 and the peripheral device 114 according to the control signal SC, the test object 104 may activate the peripheral device 114 for shooting operations. At this time, the peripheral device 114 may take a recognition picture and provide a first output image to the object 104 under test. In this example, the test object 104 uses the first output image as a communication result CR3. The control machine 116 receives the communication result CR3 to determine whether the first output image has a specific number, and generates a third test result according to the determination result. In a possible embodiment, the control machine 116 uploads the first to third test results to a web server. In this example, the tester can know whether the DUT 104 can normally control the peripheral devices 110, 112, and 114 through the input/output port 106 according to the first to third test results recorded by the web server.

In other embodiments, when the test platform 102 is electrically connected to the input/output port 108 and the peripheral device 110 according to the control signal SC, the DUT 104 may write specific data to the peripheral device 110 again, and then read a specific The data of the address is used to generate the second read data. In this example, the test object 104 uses the second read data as a communication result CR4. The control machine 116 receives the communication result CR4 to determine whether the second read data is equal to the specific data, and generates a fourth test result. When the test platform 102 is electrically connected to the input/output port 108 and the peripheral device 112 according to the control signal SC, the DUT 104 reads the vendor identification code (VID) and product identification code (PID) of the peripheral device 112 for A second test result is generated. In this example, the test object 104 uses the second detection result as a communication result CR5. The control machine 116 uses the communication result CR5 as a fifth test result. When the test platform 102 is electrically connected to the input/output port 106 and the peripheral device 114 according to the control signal SC, the test object 104 may activate the peripheral device 114 for shooting operations. at this time, The peripheral device 114 may take an identification picture and provide a second output image to the object 104 under test. In this example, the test object 104 uses the second output image as a communication result CR6. The control machine 116 receives the communication result CR6 to determine whether the second output image has a specific number, and generates a sixth test result according to the determination result. The control machine 116 uploads the fourth to sixth test results to the web server. According to the fourth to sixth test results, the user can know whether the DUT 104 can normally control the peripheral devices 110, 112, and 114 through the input/output port 108.

The present invention does not limit the structure of the control machine 116. As long as the circuit structure of CR1 to CR6 can receive the communication results of the DUT 104, it can be used as the control machine 116. In other embodiments, the control signal SC is generated by the control machine 116. In this example, the control machine 116 includes a display panel 118, a host 120, a mouse 122, and a keyboard 124.

In this embodiment, the display panel 118 is used to present a picture. This screen has many options for users to choose. In this example, the user can click on the options presented on the display panel 118 through the mouse 122 and/or the keyboard 124. The host 120 then generates a control signal SC according to the option selected by the user. The test platform 102 is electrically connected to one of the input/output ports 106 and 108 and one of the peripheral devices 110, 112, and 114 according to the control signal SC. For example, when the user wants to detect whether the test object 104 can communicate with the peripheral device 110 through the input/output port 106, the user clicks on the option presented on the display panel 118 to command the test platform 102 to electrically connect The input/output port 106 and the peripheral device 110.

In other embodiments, the display panel 118 displays the communication results CR1 to CR6 between the object 104 and the peripheral devices. The user knows whether the object under test 104 is operating normally according to the information presented on the display panel 118. The invention does not limit the type of the display panel 118. In a possible embodiment, the display panel 118 is a touch panel. In this example, the user can directly click on the options presented on the display panel 118 with a finger. In other embodiments, the user may use other input interfaces (such as a stylus) to click on the options presented on the display panel 118.

The opening 222 is used to expose the transmission port 214.

Figure 5B is a side view of the adapter of the present invention. Since the adapters 216 and 218 have the same structure, only the adapter 216 is shown in FIG. 5B. As shown in the figure, the adapter 216 includes members 511, 512, 514, a positioning member 516 and an elastic member 518. The transmission port 210 is exposed from the lower surface of the member 511. The upper surface of the member 511 contacts the member 512. In this example, a through hole 520 penetrates through the members 511 and 512. An opening of the through hole 520 serves as an opening 220 for exposing the transmission port 210. The member 514 has a groove 522. In this example, the connecting wire 212 enters the groove 522 from the side surface of the member 514, is exposed from the lower surface of the member 514, and extends into the through hole 520.

When the four positioning posts of the robotic arm are inserted into the positioning holes 524, 526, 530 At 532, it means that the robot arm has aligned the adapter 216. Therefore, the robot arm grabs the adapter 216.

The fixing holes 528 and 534 are used to fix the positioning plate 516A. When two screws (not shown) are respectively screwed into the fixing holes 528 and 534, the positioning plate 516A can be fixed on the member 514.

In some embodiments, the member 514 further includes grooves 536 and 538. In this example, the jaws of the robotic arm are snapped into the grooves 536 and 538 to grab the adapter 216. In other embodiments, when the robot arm is magnetically sucking the adapter 216, the grooves 536 and 538 can be omitted.

In a possible embodiment, the clamping jaws 610 and 612 are detachable. The tester can install different clamping jaws in the robotic arm 208 according to different adapters. In this embodiment, the positioning posts 602, 604, 606, and 608 constitute a positioning member.

Figure 7 is the main interface of the test software of the present invention. When the user starts the test software, the display panel (such as 118 in FIG. 1) displays a screen 700. The screen 700 has many Options for users to choose. In this example, the host 120 sets corresponding parameters in a test program according to the options selected by the user, and executes the test program.

Please match with Figure 1. When the user clicks on the options 702 and 706, it means that the user wants to test whether the DUT 104 can communicate with the peripheral device 110 through the input/output port 106 normally. Therefore, the host 120 instructs the test platform 102 to electrically connect the input/output port 106 and the peripheral device 110 through the control signal SC. At this time, the object under test 104 acts according to the information provided by the peripheral device 110. In a possible embodiment, the host 120 monitors the action of the object under test 104 to generate a test result and present the test result in the window 716.

In other embodiments, when the user clicks on the options 702, 708, and 710, it means that the user wants to test whether the DUT 104 can normally communicate with the peripheral devices 112 and 114 through the input/output port 106. Therefore, the host 120 instructs the test platform 102 to first electrically connect the input/output port 106 and the peripheral device 112, and monitor the action of the DUT 104 to generate a first test result, and present the first test result in the window 716 . Then, the host 120 instructs the test platform 102 to electrically connect the input/output port 106 and the peripheral device 114. At this time, the host 120 monitors the action of the object under test 104 again to generate a second test result, and present the second test result in the window 716. In other embodiments, the host 120 uploads each test result to the web server. Therefore, the tester does not have to stay by the object to be tested all the time, and can remotely monitor the test results in real time and improve work efficiency.

In one possible embodiment, when the test platform 102 fails to electrically connect to the input/output port 106, the window 716 displays a failure message. In this example, the tester presses option 712 to suspend the operation of the test platform 102. When the tester removes the fault, he then clicks option 714 to instruct the test platform 102 to continue its action.

In other embodiments, the user controls the robot arm in the test platform 102 through the options 718, 720, 722, and 724 to troubleshoot the test platform 102. For example, when an alignment error occurs in the robot arm of the test platform 102, the robot arm may not be able to align the adaptor, and therefore cannot move the adaptor. In this example, the user clicks option 718. Therefore, the host 120 executes an initialization program to command the robot arm to return to an initial position. In some embodiments, when the user clicks the option 720, the host 120 commands the robotic arm to stop. When the user clicks the option 722, the host 120 commands the mechanical arm to pause. When the user clicks the option 724, the host 120 commands the mechanical arm to resume movement.

Figure 8 is a schematic diagram of the host control method of the present invention. Please cooperate with Figure 2 of this case. First, the control circuit 200 of the host 120 sets the parameters m and n to be equal to 1 (step S801). Next, the control circuit 200 commands the robotic arm 208 to move the transmission port 210 according to the parameter m (step S802). In this embodiment, since the parameter m=1, the control circuit 200 requests the robotic arm 208 to insert the transmission port 210 into the connection terminal CT13 of the test port TP1.

Next, the control circuit 200 determines whether the transmission port 210 is inserted into the connection terminal CT13 (step S803). In a possible embodiment, the control circuit 200 determines whether the transmission port 210 is inserted into the connection terminal CT13 according to the level of a first specific pin of the connection terminal CT13. For example, when the level of the first specific pin of the connection terminal CT13 is not equal to a first preset value, it means that the transmission port 210 is not inserted into the connection terminal CT13. Therefore, the control circuit 200 instructs the robot arm 208 to suspend the operation (step S804).

When the level of the first specific pin of the connection terminal CT13 is equal to the first preset value, it means that the transmission port 210 is inserted into the connection terminal CT13. Therefore, the control circuit 200 commands the robotic arm 208 to move the transmission port 214 according to the parameter n (step S805). In this embodiment, due to the The number n=1, so the control circuit 200 commands the robotic arm 208 to insert the transmission port 214 into the connection terminal CT15 of the peripheral port PP1.

Next, the control circuit 200 determines whether the transmission port 214 is inserted into the connection terminal CT15 (step S806). In a possible embodiment, the control circuit 200 determines whether the transmission port 214 is inserted into the connection terminal CT15 according to the level of a second specific pin of the connection terminal CT13. For example, when the second specific pin of the connection terminal CT13 is not equal to a second preset value, it means that the transmission port 214 is not inserted into the connection terminal CT15. Therefore, the control circuit 200 suspends the operation of the robot arm 208 (step S807).

When the second specific pin of the connection terminal CT13 is equal to the second preset value, it means that the transmission port 214 is inserted into the connection terminal CT15. Therefore, the control circuit 200 monitors the action of the test object 104 to generate a first test result (step S808). Next, the control circuit 200 determines whether the parameter n reaches a first critical value (step S809). In a possible embodiment, the first threshold is related to the number of peripheral devices. In this embodiment, since the test platform 102 is coupled to three peripheral devices, the first threshold value is 3. In other embodiments, if the test system platform 102 is coupled to seventeen peripheral devices, the first threshold value is 17.

Since the parameter n=1 does not reach the first critical value (such as 3), the control circuit 200 sets the parameter n=2 (step S810), and returns to step S805, again according to the parameter n, commands the robotic arm 208 to move the transmission port 214 . In this example, since the parameter n=2, the robot arm 208 inserts the transmission port 214 into the connection terminal CT16. Next, the control circuit 200 determines whether the transmission port 214 is inserted into the connection terminal CT16 (step S806). When the transmission port 214 is not inserted into the connection terminal CT16, the control circuit 200 suspends the test operation (step S807).

When the transmission port 214 is inserted into the connection terminal CT16, the control circuit 200 monitors the action of the DUT 104 to generate a second test result (step S808). Next, control The circuit 200 determines whether the parameter n reaches the first critical value (step S809). At this time, since the parameter n=2 does not reach the first critical value (such as 3), the control circuit 200 sets the parameter n=3 (step S810), and returns to step S805 to instruct the robotic arm 208 to insert the transmission port 214 into the connection Terminal CT17. The control circuit 200 determines whether the transmission port 214 is inserted into the connection terminal CT17 (step S806). When the transmission port 214 is not inserted into the connection terminal CT17, the control circuit 200 suspends the test operation (step S807).

When the transmission port 214 is inserted into the connection terminal CT17, the control circuit 200 monitors the action of the DUT 104 to generate a third test result (step S808). Next, the control circuit 200 determines whether the parameter n reaches the first critical value (step S809). At this time, since the parameter n=3 and the first critical value has been reached, the control circuit 200 determines whether the parameter m has reached a second critical value (step S811). In this embodiment, the second threshold is related to the number of input/output ports to be tested by the DUT 104. Since the DUT 104 has two rounds of input/output ports, the second threshold value is 2. In this example, since the parameter m=1 and the second critical value is not reached, the control circuit 200 sets the parameter m=2 and sets the parameter n=1, and then returns to step S802.

Since the parameter m=2, the control circuit 200 commands the robotic arm 208 to move the transmission port 210 to insert the transmission port 210 into the connection terminal CT14 (step S802). The control circuit 200 determines whether the transmission port 210 is inserted into the connection terminal CT14 (step S803). When the transmission port 210 is not inserted into the connection terminal CT14, the control circuit 200 suspends the test operation (step S804).

When the transmission port 210 is inserted into the connection terminal CT14, the control circuit 200 instructs the robotic arm 208 to move the transmission port 214 according to the parameter n. At this time, since the parameter n=1, the robot arm 208 inserts the transmission port 214 into the connection terminal CT15. Next, the control circuit 200 determines the transmission Whether the input port 214 is inserted into the connection terminal CT15 (step S806). When the transmission port 214 is not inserted into the connection terminal CT15, the control circuit 200 suspends the test operation (step S807).

When the transmission port 214 is inserted into the connection terminal CT15, the control circuit 200 monitors the action of the DUT 104 to generate a fourth test result (step S808). Next, the control circuit 200 determines whether the parameter n reaches the first critical value (step S809). At this time, since the parameter n=1, the first critical value (for example, 3) is not reached, the control circuit 200 sets the parameter n=2 (step S810), and returns to step S805 to instruct the robotic arm 208 to insert the transmission port 214 into the connection Terminal CT16. The control circuit 200 determines whether the transmission port 214 is inserted into the connection terminal CT16 (step S806). When the transmission port 214 is not inserted into the connection terminal CT16, the control circuit 200 suspends the test operation (step S807).

When the transmission port 214 is inserted into the connection terminal CT16, the control circuit 200 monitors the action of the DUT 104 to generate a fifth test result (step S808). Next, the control circuit 200 determines whether the parameter n reaches the first critical value (step S809). At this time, since the parameter n=2 does not reach the first critical value (such as 3), the control circuit 200 sets the parameter n=3 (step S810), and returns to step S805 to instruct the robotic arm 208 to insert the transmission port 214 into the connection Terminal CT17. The control circuit 200 determines whether the transmission port 214 is inserted into the connection terminal CT17 (step S806). When the transmission port 214 is not inserted into the connection terminal CT17, the control circuit 200 suspends the test operation (step S807).

When the transmission port 214 is inserted into the connection terminal CT17, the control circuit 200 monitors the action of the DUT 104 to generate a sixth test result (step S808). Next, the control circuit 200 determines whether the parameter n reaches the first critical value (step S809). At this time, since the parameter n=3 has reached the first critical value, the control circuit 200 determines whether the parameter m reaches a second critical value. Value (step S811). At this time, since the parameter m=2 has reached the second critical value, the control circuit 200 ends the test procedure (step S813).

In other embodiments, the control circuit 200 uploads the first to sixth test results to the web server. The tester can monitor the movement of the object under test 104 in real time without having to be on site all the time. In some embodiments, when a tester opens a test application and clicks the "test result query" option, the tester can connect to the web server to query the test results of all DUTs. In this example, the web server will display the specific error content to assist the tester in the analysis.

In this embodiment, step S801 is to set the parameters m and n to a value of 1, but it is not used to limit the present invention. In other embodiments, the control circuit 200 sets the parameters m and n according to the selected option on the screen 700 in FIG. 7. For example, when the user clicks the option 702, the control circuit 200 sets the parameter m=1. At this time, the control circuit 200 may set the second threshold value to be 1. When the user clicks the option 704, the control circuit 200 sets the parameter m=2. In this example, the control circuit 200 may set the second threshold to be a value of 2. In some examples, when the user selects the options 702 and 704, the control circuit 200 sets the parameter m=1, and sets the second threshold to the value 2.

In addition, when the user clicks the option 706, the control circuit 200 sets the parameter n=1. In this example, the control circuit 200 may set the first threshold value to be 1. When the user clicks the option 708, the control circuit 200 sets the parameter n=2. In this example, the control circuit 200 may set the first threshold to be a value of 2. When the user clicks the option 710, the control circuit 200 sets the parameter n=3. In this example, the control circuit 200 may set the first threshold The value is 3. In other embodiments, when the user clicks on the options 706, 708, and 710, the control circuit 200 sets the parameter n=1, and sets the first threshold to the value 3.

In a possible embodiment, step S801 further initializes the robotic arm 208 to command the robotic arm 208 to return to an initial position. In another possible embodiment, step S801 reads the information of the test object 104, such as the BIOS version and model of the test object 104. In other embodiments, step S801 records the test time.
