The detection personnel perform the automatic detection method for the device under test 20 by the aforementioned automatic detection system 10, which includes two embodiments, which will be separately described below.

In the first method embodiment, please refer to FIG. 5, and please refer to FIG. 1 to FIG. 4 simultaneously. When the detecting person performs the automatic detecting method of the present invention, first, the automatic detecting system 10 is provided (S101); The inspector electrically connects the device under test 20 to the circuit board 101 of the automated detection system 10 (S105), for example, inserts the graphics card to be tested into the PCI connection interface of the circuit board; and then performs detection by the processing unit 102 of the circuit board 101. The software executes the test program through the detection software device 20 (S110); then, the processing unit 102 executes a test item to be tested (S115), or executes a plurality of different test items in a predetermined order, and the processing unit The control unit 103 transmits the status signal to the control unit 103 of the automated detection system 10, wherein the processing unit 102 can continuously transmit the status signal to the control unit 103; or transmits the status signal to the control unit 103 every predetermined time period for The control unit 103 is enabled to receive a message that the test program is normally performed. After that, the control unit 103 determines whether to reset the automatic detection system 10 according to whether the status signal is received or not. The determination mechanism includes three implementation manners, which are respectively described below.

In the first embodiment, please refer to FIG. 5, wherein, if the device under test 20 passes the specific test item of the test program, the processing unit 102 correspondingly transmits the status signal to the control unit 103 (S120), and the control unit 103 receives The status signal indicates that the processing unit 102 is in a normal operating state, so the control unit 103 does not act according to the status signal (S125); the detection software of the processing unit 102 is based on the next test item of the execution of the test program (S130); 20 The specific test item that fails the test procedure causes the processing unit 102 to crash and cannot transmit the status signal to the control unit 103, so that the control unit 103 does not receive the status signal transmitted by the processing unit 102 (S135), in this embodiment. The control unit 103 determines that the current test item causes the automatic detection system 10 to be down (S140). At this time, the control unit 103 sends a reset signal to the reset pin 104 through the signal line 105, and the reset pin 104 corresponds to The reset signal restarts the automated detection system 10 (S145) to resume the test process by the recovery processing unit 102 executing the detection software.

The judgment mechanism of the second embodiment is substantially similar to the first embodiment, except that the judgment mechanism of the second embodiment is judged by the timing module 107. Please refer to FIG. 6 and refer to the same. 5, first, the tester sets the unit time (S201), for example, 10 seconds, with the timing module 107 of the automated detection system 10 before performing the test, and the unit time may be equal to or longer than the time at which the processing unit transmits the status signal. At the same time, the control unit 103 starts the timing module 107 after receiving the status signal of the processing unit 102 for the first time (S205), and the determining mechanism of the control unit 103 according to the embodiment is based on whether the control unit 103 is in the unit time. Receiving the status signal to determine whether to reset the automatic detection system 10, wherein if the control unit 103 receives the status signal within the unit time, indicating that the test program of the processing unit 102 is normally executed, the control unit 103 resets the timing module 107 (S215) The control unit 103 does not actuate the automatic detection system 10 according to the status signal (S125), so that the detection software of the processing unit 102 executes the next test item as described above (S130); if the control unit 103 does not receive the unit time To the status signal, the control unit 103 determines that the automatic detection system 10 is down (S140), and transmits a reset signal to the reset pin 104 to restart the automatic detection system 10 by the reset pin 104 (S145). The test processing is performed by the recovery processing unit 102 executing the detection software.

The judgment mechanism of the third embodiment is substantially similar to the second embodiment, except that the judgment mechanism of the third embodiment is not only matched with the timing module 107, but also increases the number of times of disconnection, please refer to 7 and referring to FIG. 5, first, the tester sets the unit time and the predetermined number of times (S301), for example, 10 seconds and 5 times, by the timing module 107 of the automatic detection system 10 before performing the test, and the control unit 103 is also the same. When the status signal of the processing unit 102 is received for the first time, the timing module 107 is started (S205). The determination mechanism of the control unit 103 in this embodiment is substantially similar to that of the second embodiment, and the difference is that if the control unit 103 in single The status signal is not received within the bit time, and the control unit 103 calculates a number of times of disconnection (S320); that is, if the status signal is not received every unit time, the number of times of the disconnection is calculated once, and the calculation is performed by the number of times of accumulation or deduction. Determining whether the automatic detection system 10 is down, therefore, the control unit 103 further determines whether the number of times of disconnection is equal to a predetermined number of times (S325), to determine whether the automatic detection system 10 is down or not, and if the number of times of the automatic detection system 10 is not equal to the predetermined number of times, the control unit continues to receive The status signal (S310); if the number of times of the disconnection is equal to the predetermined number of times, the control unit 103 determines that the automatic detection system 10 is down (S140), and generates a reset signal corresponding to the reset pin 104, so that the reset pin 104 corresponds to the weight. The signal number restarts the automated detection system 10 (S145), and the recovery processing unit 102 executes the detection software to continue the test procedure.

The manner in which the second and third embodiments are calculated by the timing module 107 to calculate the unit time and the predetermined number of times helps to increase the fault tolerance of the control unit 102 to determine whether the automatic detection system 10 is down, in units of 10 seconds and a predetermined number of times. For comparison, the control unit 102 of the first embodiment does not receive the status signal, that is, determines the crash and restarts the system; the second embodiment determines that the status signal is not received after more than 10 seconds. Downtime and restart the system; in the third embodiment, the system is judged and restarted only when the status signal is not received within 10 seconds, that is, compared with the first embodiment, The second and third embodiments each have a fault tolerance of 10 seconds or 50 seconds, respectively, to prevent the processing unit 102 of the automated detection system 10 from being misjudged due to slow processing, thereby increasing the accuracy of the overall test procedure.

It should be noted that, in this embodiment, the control unit 103 determines that the processing unit 102 is down according to any one of the first three implementation manners, and restarts the automatic detection system 10 to restore the test program, and then detects the software. In the test program, it is first determined which test items have passed the test, and the test items that caused the crash are skipped before the next test item is executed (S15), that is, in the embodiment, the detection software of the processing unit 102 does not Re-execute the test project that caused the previous crash, and skip the test project and execute the next test project, which will help increase the efficiency of the overall test.

As described above, after each test item and the judgment mechanism in the test procedure as described above, the test software determines whether the test program is completed (S155), and if it is judged that the test program has not been completed, the test software corresponding execution is performed. Test item (S115); if it is judged that the test program has been completed, the processing unit 102 converts the test result of each test item in the test program into one test The test unit 102 transmits the test information to the output module 106 of the automatic detection system 10 (S160); the output module 106 presents the test result of the software test device 20 according to the test information (S165), and the test information is presented. The method of recording has been explained in the previous paragraph, and the inventors will not repeat them here.

Through the automatic detection method of the embodiment, the automatic detection system 10 can be The test items of the test program are automatically executed for the device under test 20, and when the test items are not passed, the automatic detection system 10 is reset via the control unit 102 to continue the test process, so the tester does not need to monitor the overall test. The process does not rely on the tester to eliminate the test interruption caused by the crash, thereby greatly increasing the efficiency of the test and reducing the labor cost.

The steps of the second method embodiment are substantially similar to the first method embodiment, and The three determination implementations of the control unit 103 of the first embodiment can also be applied to the second method embodiment, except that the difference is that, referring to FIG. 8, the control unit 103 issues a reset signal and restarts the automatic detection system. (S445), after the recovery processing unit 102 executes the detection software to continue the test procedure, in the embodiment, the detection soft system executes the same test item again in the test program (S450), that is, the detection software re-targets the device to be tested. 20 Executing the test item that caused the previous crash, if the device under test 20 passes the detection item, the processing unit 102 correspondingly transmits the status signal to the control unit 103 (S420), and executes the next test item (S430); If the secondary device under test 20 still fails to pass the detection item, the control unit 103 does not receive the status signal (S455), and the control unit 103 correspondingly issues the reset signal again to restart the automatic detection system 10 (S460), and In this test procedure, the test software skips the test item that led to the base, and executes the next test item (S465) to complete the overall test process.

Therefore, the automated detection method of the second method embodiment is directed to causing a crash The test items are repeatedly tested to avoid misjudgment caused by system delays, thereby improving the accuracy of the test.

The detection software executed by the processing unit in the above automated detection system, this The invention can adopt corresponding testing procedures for various products to automatically test different items of the product, so it is not necessary to rely on the testing personnel to manually operate each test item in each testing program, thereby greatly improving the efficiency of the testing process, and at the same time, The program and each test item have been previously input into the test program of the test software, even though the tester does not have relevant professional knowledge, the present invention The automated inspection system is still able to automate the complete testing process to confirm that the product is defective, which also helps to reduce the personnel cost of quality control.

In addition, it is judged by the control unit whether to reset according to whether the status signal is received or not. The automatic detection system, when the automatic detection system of the invention is down because the product to be tested fails to pass the test item, the control unit can restart the automatic detection system to resume the processing unit to execute the detection software to continue the test procedure, so the inspection personnel do not need to go through the whole process. The monitoring test program is not used to manually eliminate the downtime problem. Compared with the conventional detection system and method, the present invention effectively reduces the burden on the inspector and greatly improves the efficiency of the overall testing process to improve the shipping speed of the product.

Moreover, the control unit of the present invention can be matched with the timing and counting of the timing module. Secondly, corresponding to the judgment mechanism derived from three different implementation modes, and the detection software in the two method embodiments, after repeating the system for testing, the same item is repeatedly tested, or the test item causing the crash is skipped. Different test policy choices, in order to increase the test efficiency according to the manufacturer's needs, or increase the system's fault tolerance, to further improve the accuracy of the test.

In addition, with the output module of the present invention, the inspector can set up according to the demand That is, the test result of the device to be tested is grasped to correspondingly judge whether the device to be tested is normal or defective, and the test result of each pen can be further recorded for subsequent inquiry or review by other departments.
