Detailed ways

As shown in FIG. 1 , it is an operating environment diagram of a preferred embodiment of the computer mainboard power-on/off test system of the present invention. The computer motherboard switch test system 10 runs on a kind of electronic hardware with data processing capability and capable of running software, such as a microcontroller (Micro Controlling Unit, MCU). In this embodiment, the single-chip microcomputer 1 is taken as an example for illustration, and the single-chip microcomputer 1 is respectively connected with the main board 4 , the computer power supply 5 , the input device 2 and the display device 3 . The computer mainboard switch test system 10 is used to test whether the mainboard 4 is on or off by detecting the system voltage on the computer power supply 5 according to the test parameters set by the input device 2, and output the test results to the display device 3. The display device 3 includes an indicator light, an alarm and a nixie tube (not shown in FIG. 1 ). Described indicator lamp is used for sending the prompt message of test success when mainboard 4 tests pass, and described alarm is used for sending the alarm message of test failure when mainboard 4 tests fail, and described nixie tube is used for displaying the current test times of mainboard 4. The indicator light may be a light emitting diode (Light Emitting Diode, LED), and the digital tube may be a seven-segment LED digital tube.

The mainboard 4 is connected with a computer power supply 5 and is powered by the computer power supply 5 . If it is necessary to test the switching performance of the mainboard 4 into the operating system, the mainboard 4 is connected with the hard disk (not shown in Fig. 1). The mainboard switch test system 10 of the computer controls its switch machine by sending on/off signal to mainboard 4, and this on/off signal is the control signal of the power switch of mainboard 4, i.e. Power Button control signal. The computer power supply 5 can provide multiple different system voltages for the motherboard 4, such as 5V_SYS, 3V_SYS, 12V_SYS. The computer mainboard switch test system 10 can judge whether the switch of the mainboard 4 is normal by detecting the level of these system voltages. In this embodiment, the switch of the mainboard 4 is tested by detecting 5V_SYS. When the mainboard 4 is turned on normally, the 5V_SYS on the computer power supply 5 is a relatively high level of about 5V, and when the mainboard 4 is normally shut down, the 5V_SYS on the computer power supply 5 is a relatively low level lower than 2V. The single chip microcomputer 1 can detect whether 5V_SYS is a relatively high level or a relatively low level. Mainboard 4 detects 5V_SYS after booting, if no relatively high level is detected, it indicates that booting fails (i.e. shutdown is abnormal); mainboard 4 detects 5V_SYS after shutting down, if no relatively low level is detected, then it indicates shutdown failure.

As shown in FIG. 2 , it is a functional block diagram of a preferred embodiment of the computer mainboard power-on/off test system 10 of the present invention.

The computer motherboard switch test system 10 includes: an initialization module 100, a setting module 101, a power-on test module 102, a power-off test module 103, a power-off verification module 104, a recording module 105, a display module 106 and a judgment module 107.

The initialization module 100 is used for initializing the single-chip microcomputer 1. The initialization setting of the single-chip microcomputer 1 includes register setting, timer setting, interrupt setting and the like.

The setting module 101 is used for setting test parameters, which are input by the user through the input device 2 . The test parameters include test times, startup delay and shutdown delay. The power-on delay refers to the time interval from sending the power-on signal to sending the power-off signal, and the power-off delay refers to the time interval from sending the power-off signal to sending the power-on signal. In this embodiment, both the power-on signal and the power-off signal are control signals of the power switch of the motherboard 4, and are instantaneous signals. If it is not necessary to test the power-on/off performance of the mainboard 4 entering the operating system, a relatively small start-up delay and shutdown delay can be set, such as both being set to 6 seconds; if it is necessary to test the power-on/off performance of the mainboard 4 entering the operating system, set Relatively large power-on delay and power-off delay, for example, both are set to 50 seconds. The user sets the test parameters through the input device 2 (such as a keyboard or keys). For example, set the number of tests to 1000 by pressing the button, and both the power-on delay and the power-off delay are 6 seconds.

The power-on test module 102 is used to send a power-on signal to the mainboard 4, and performs timing according to the power-on delay set by the setting module 101, detects the system voltage when the power-on delay arrives, and judges whether the system voltage is a relatively high level, thereby Determine whether the mainboard 4 is powered on normally. When the mainboard 4 is turned on normally, the detected system voltage is at a relatively high level.

The shutdown test module 103 is used to send a shutdown signal to the motherboard 4 when the mainboard 4 is turned on normally, and to perform timing according to the shutdown delay set by the setting module 101, detect the system voltage when the shutdown delay arrives, and judge whether the shutdown system voltage is is a relatively low level, thereby judging whether the mainboard 4 is shut down normally. When the motherboard 4 is shut down normally, the detected system voltage is relatively low level.

The shutdown verification module 104 is used to verify whether the shutdown failure is caused by an accident, so as to eliminate the wrong test result caused by entering the operating system. Assuming that the boot delay is set to 50 seconds, and the computer enters the operating system after booting for 48 seconds, then the boot test module 102 sends a shutdown signal through 50 seconds after sending the boot signal, and now the mainboard 4 is entering the operating system. The mainboard 4 can shield the shutdown signal (the shielding time is about 10 seconds) when entering the operating system, and the mainboard 4 cannot respond to the shutdown signal and cause the shutdown to be abnormal. In order to avoid this situation, the shutdown verification is performed after the shutdown failure is tested, and the shutdown signal is sent again after a delay for a period of time (such as 10 seconds) and the system voltage is detected. If the system voltage is not relatively low, it is determined that the verification has not passed. If the system voltage is at a relatively low level, it is determined that the verification is passed. Shutdown verification can also repeat several times to send shutdown signal and detect system voltage.

The recording module 105 is used for recording test results. During a test of the mainboard 4, if the power-on is normal and the power-off is normal (normal power-off includes passing the power-off verification), the test is passed. In this embodiment, the recording module 105 records the current number of tests and the number of passed tests (abbreviated as the number of passes). For each test, the current number of tests is increased by 1, and each time a test is passed, the number of passes is increased by 1. If one fails, the number of passes recorded at the end of the test is 0. If each test is passed within the set number of tests, the number of passes recorded at the end of the test is equal to the set number of tests. The recording module 105 may also choose to record the number of failed tests.

The display module 106 is used to control the digital tube of the display device 3 to display the current number of tests at the end of each test, to control the indicator light of the display device 3 to send a prompt message that the test is passed when the entire test is passed, and to control the display device 3 when the test fails. The annunciator sends out the alarm message of test failure. If each test is passed within the set number of tests, the entire test is passed. If the power-on fails or the power-off verification fails, the test fails. It can be indicated that the entire test is passed by controlling the indicator light of the display device 3 to continuously light up or flash.

The judging module 107 is used for judging whether to continue the test. In this embodiment, if the current number of tests is greater than the number of passes or the current number of tests reaches the set number of tests, the determination module 107 determines to end the test. If the current number of tests is greater than the number of passes, it indicates that the startup failed or failed the shutdown verification. You can also choose to end the test only when the current number of tests reaches the set number of tests.

As shown in FIG. 3 , it is a flow chart of a preferred embodiment of the test method for switching on and off the mainboard of the computer according to the present invention.

In step S200, the initialization module 100 performs initialization settings on the single-chip microcomputer 1. The initialization settings of the single-chip microcomputer 1 include register settings, timer settings, interrupt settings, and the like.

In step S201, the setting module 101 sets test parameters. The test parameters are input by the user through the input device 2, such as the number of tests, start-up delay, and shutdown delay. The test parameters can be set according to the actual needs of the user. If it is not necessary to test the power-on/off performance of the mainboard 4 entering the operating system, a relatively small start-up delay and shutdown delay can be set, such as both being set to 6 seconds; if it is necessary to test the power-on/off performance of the mainboard 4 entering the operating system, set Relatively large power-on delay and power-off delay, for example, both are set to 50 seconds.

Step S202 , the power-on test module 102 sends a power-on signal to the main board 4 , and the power-on signal is a control signal of a power switch of the main board 4 .

In step S203, the power-on test module 102 starts timing according to the set power-on delay.

In step S204, when the preset power-on delay is reached, the power-on test module 102 detects the system voltage. The system voltage detected in this embodiment is 5V_SYS of the computer power supply 5 .

In step S205, the power-on test module 102 judges whether the system voltage is at a relatively high level, if not, the current test fails, and the process goes to step S211.

Step S206 , if it is detected that the system voltage is at a relatively high level, it means that the mainboard 4 is powered on normally during the test. At this time, the shutdown test module 103 sends a shutdown signal to the mainboard 4 . The shutdown signal is a control signal of a power switch.

In step S207, the shutdown test module 103 starts timing according to the preset shutdown delay.

Step S208 , when the timer reaches the preset shutdown delay, the shutdown test module 103 detects the system voltage, which is 5V_SYS of the computer power supply 5 .

In step S209, the shutdown test module 103 judges whether the system voltage is at a relatively low level. If it is detected that the system voltage is at a relatively low level, it means that the mainboard 4 is normally shut down during the test, and the current test is passed. Go to step S211.

In step S210, if the system voltage detected by the shutdown test module 103 is not at a relatively low level, which indicates that the shutdown fails, then a shutdown verification is performed to eliminate erroneous test results caused by entering the operating system. The steps of the shutdown verification are as follows: the shutdown verification module 104 sends a shutdown signal after a delay of 10 seconds, and detects the system voltage after a preset shutdown delay. If it is detected that the system voltage is at a relatively low level, the verification is passed; if it is detected that the system voltage is not at a relatively low level, the verification is not passed; if the verification is passed, the current test is passed.

In step S211, the recording module 105 records the current number of tests and the number of passes. If step S209 detects that the system voltage is at a relatively low level or step S210 passes the shutdown verification, the test is passed, and the number of passes is increased by 1. The current number of tests is incremented by 1 for each test.

Step S212, the display module 106 controls the digital tube of the display device 3 to display the current number of tests of the main board 4; if the current number of tests is greater than the number of passes, the display module 106 controls the alarm of the display device 3 to send an alarm message; For a certain number of tests, the display module 106 controls the indicator light of the display device 3 to keep on to indicate that the entire test is passed.

Step S213 , the determination module 107 determines whether to continue the test according to the test result obtained by the recording module 105 and the number of tests set by the setting module 101 . If the current number of tests is greater than the number of passes or the current number of tests reaches the set number of tests, the determination module 107 determines to end the test, otherwise, go to step S202 for the next test.

In the process of this preferred embodiment, once the startup fails or fails to pass the shutdown verification, an alarm message is sent and the test ends. This process can shorten the test time and quickly find the switch failure. Other testing processes can also be adopted, such as recording the number of failures after each startup failure or shutdown failure, and then continuing to the next test until the set number of tests is reached.

The above-mentioned embodiment adopts the order of power-on test first and then power-off test according to the general sequence of mainboard power-on and power-off testing. If the order of power-off test and then power-off test is adopted, it does not deviate from the spirit and scope of the present invention.
