检测主机板的检测装置及其检测方法 Detecting device and method for detecting motherboard

技术领域technical field

本发明涉及一种检测主机板的检测装置及其检测方法，特别涉及一种反复将主机板开/关机以检测主机板状态的检测装置及检测方法。The invention relates to a detection device and a detection method for detecting a main board, in particular to a detection device and a detection method for repeatedly turning on/off the main board to detect the state of the main board.

背景技术Background technique

主机板(Motherboard；Mainboard；Mobo；MLB；MB)，是构成复杂电子系统(例如电子计算器)中唯一或最主要的电路板，因此主机板是否能正确的运作是非常重要的。Motherboard (Motherboard; Mainboard; Mobo; MLB; MB) is the only or most important circuit board that constitutes a complex electronic system (such as an electronic calculator), so whether the motherboard can operate correctly is very important.

为了要确认主机板能够正常的运作，在主机板制作完成出厂前，必须要进行一连串的测试，其中有一项测试便是开关机的测试，用来测试主机板在开关机的过程遇到各种状况时是否能够继续正常运作，例如在开机完成之前便将电源关闭以测试主机板能否在下次启动时正常的开机，或连续不断的开关主机板以测试主机板在每次的开关时都能够正常的完成开关机等。In order to confirm the normal operation of the motherboard, a series of tests must be carried out before the motherboard is manufactured and shipped. One of the tests is the power-on and power-off test, which is used to test that the motherboard encounters various problems during the power-on and power-off process. Whether it can continue to operate normally, such as turning off the power before the boot is complete to test whether the main board can boot normally at the next boot, or continuously switching the main board to test whether the main board can be turned on and off every time Normal completion of the switch machine and so on.

在一般的情况下，开关主机板需要由人按下电源开关以产生开关机信号至主机板，使得主机板进行开关机，但是在测试时需要不断的产生开关机信号，所以不太可能由人不断的按下电源开关来进行测试，此外，由于目前对主机板测试的标准越来越高，且测试精准度要求也越来越高，因此现在有一种可以测试主机板开关机是否正常的测试机器，它是由一台计算机再加上一个测试模块组成，在测试模块与主机板连接之后，通过计算机中的软件控制来完成测试主机板开关机的工作。通过这样的测试机器可以解决需要不断的由人按下电源开关的无谓动作，但是，测试机器却有着体积庞大、携带不便、维护不易、成本高昂、耗电量高等问题，此外，测试机器也没有测试主机板是否正确的开始开机或是完成关机，这样对后续的关机或开机会出现误判的问题，因此，如何能够提供一种轻便而可以测试主机板开关机是否正常的测试机器，成为待解决的问题。In general, switching the motherboard needs to be pressed by a person to generate a power switch signal to the motherboard, so that the motherboard can be turned on and off. However, it is necessary to continuously generate the power on and off signal during the test, so it is unlikely to be performed by a human. Continuously press the power switch to test. In addition, because the current standard for motherboard testing is getting higher and higher, and the test accuracy requirements are getting higher and higher, so now there is a test that can test whether the motherboard is turned on or off normally. The machine is composed of a computer and a test module. After the test module is connected to the main board, the work of testing the power on and off of the main board is completed through the software control in the computer. Such a test machine can solve the needless action of constantly pressing the power switch by people. However, the test machine has problems such as bulky, inconvenient to carry, difficult to maintain, high cost, and high power consumption. In addition, the test machine has no To test whether the mainboard is started or finished shutting down correctly, there will be misjudgment of the subsequent shutting down or starting up. Therefore, how to provide a portable test machine that can test whether the mainboard is turned on or off is a waiting solved problem.

As shown in the figure, the detection device 100 of the present invention includes an input device 110, a processing circuit 120, and a display device 130, wherein the input device 110 is coupled to the processing circuit 120 and is responsible for providing the input of the number of detections, power-on time and power-off time; the processing circuit 120 is coupled with the input device 110 and the mainboard 200, and stores the output status of the basic input/output system (Basic Input/Output System; BIOS) on the mainboard after the Power On Self Test (POST) is completed. The value is a predetermined state value, responsible for sending the power-on signal to the main board 200 when the elapsed time matches the shutdown time after the main board 200 is shut down, and receiving the status signal from the main board 200, and responsible for the time when the main board 200 is turned on When the power-on time is met, judge the status signal; when the status signal does not match the preset status value, generate the first error signal; when the status signal matches the preset status value, send the shutdown signal to the motherboard 200 to shut down the motherboard, and judge the host When the voltage transmitted from the board 200 is not zero, generate a second error signal, and be responsible for sending the power-on signal to the motherboard 200 again after the power-off time expires when the number of times the power-on signal is transmitted is different from the detection number of times; the display device 130 , coupled with the processing circuit 120, responsible for displaying the first error signal and the second error signal.

接着以一个实施例来说明本发明的运作系统与方法，本实施例所提供的输入装置110以指拨开关为例，但本发明所提供的输入装置并不以指拨开关为限；本实施例所提供的显示装置130以七段显示器为例，但本发明所提供的显示装置并不以七段显示器为限，其它例如液晶显示器(LCD)等，所有公知可显示文字、数字的显示装置均可为本发明所使用。同时请参照图2A本发明所提供的反复开关以检测主机板的方法流程图。在使用本发明所提供的检测装置100前，检测装置需要先设定预定状态值(步骤301)，设定的方式例如由输入装置110输入至处理电路120中，或是直接将预定状态值存入处理电路120中等。接着要连接主机板200与本发明所提供的检测装置100(步骤310)，其中，主机板200上的基本输入/输出系统210需要与处理电路120连接，传送表示主机板200开机的状态的信号；处理电路120还与主机板200另外连接有三条信号线，第一信号线201传送开机信号与关机信号，第二信号线202传送开机才有的电压，第三信号线203则传送开/关机信号。Next, an embodiment is used to illustrate the operating system and method of the present invention. The input device 110 provided in this embodiment is an example of a dip switch, but the input device provided by the present invention is not limited to a dip switch; The display device 130 provided is an example with a seven-segment display, but the display device provided by the present invention is not limited to a seven-segment display, other such as a liquid crystal display (LCD), etc., all known display devices that can display characters and numbers can be used in the present invention. At the same time, please refer to FIG. 2A , the flow chart of the method for repeatedly switching on and off to detect the motherboard provided by the present invention. Before using the detection device 100 provided by the present invention, the detection device needs to set a predetermined state value (step 301). into the processing circuit 120 and so on. Then connect the mainboard 200 with the detection device 100 provided by the present invention (step 310), wherein the basic input/output system 210 on the mainboard 200 needs to be connected with the processing circuit 120, and transmit a signal representing the state of the mainboard 200 starting up The processing circuit 120 is also connected with the motherboard 200 with three signal lines, the first signal line 201 transmits the power-on signal and the power-off signal, the second signal line 202 transmits the voltage that is only available when the machine is turned on, and the third signal line 203 transmits the on/off signal Signal.

当主机板200与本发明所提供的检测装置100连接完成后，用户可以开始进行测试，首先要使用指拨开关依序输入开机时间、关机时间与检测次数(步骤320)，处理电路120会将接收到的信号依序视为开机时间、关机时间与检测次数，但本发明并不以此输入为限，例如可以使用额外的指拨开关设定要输入的数据为开机时间、关机时间与检测次数中的哪一种，处理电路120会依据设定将输入的信号读入对应的开机时间、关机时间或检测次数中。After the motherboard 200 is connected to the detection device 100 provided by the present invention, the user can start testing. First, use the dip switch to input the startup time, shutdown time and detection times in sequence (step 320), and the processing circuit 120 will receive The received signals are regarded as the power-on time, power-off time and detection times in sequence, but the present invention is not limited to this input, for example, an additional dip switch can be used to set the data to be input as power-on time, power-off time and detection times According to which one, the processing circuit 120 will read the input signal into the corresponding power-on time, power-off time or detection times according to the setting.

在开机时间、关机时间与检测次数输入完成之后，处理电路120会开始测试主机板(步骤330)，详细的测试过程将在之后说明，若在测试过程中发生错误(步骤340)，则处理电路120会停止测试，并把与发生的错误相对应的错误信号传送到七段显示器中显示给用户(步骤350)。After the input of the power-on time, the power-off time and the detection times are completed, the processing circuit 120 will start to test the motherboard (step 330). The detailed test process will be explained later. If an error occurs during the test (step 340), the processing circuit will 120 will stop the test, and send error signals corresponding to the errors to the seven-segment display for display to the user (step 350).

接着将详细说明处理电路测试主机板(步骤330)的过程，并请参考图2B，当处理电路120开始测试主机板时，处理电路120会通过第二信号线202的电压判断主机板200的状态，若此时第二信号线202的电压为零，则主机板200为关机状态，处理电路120会通过第三信号线203传送开机信号至主机板200，主机板200接收到开机信号之后便会进行开机的程序(步骤33 1)；若此时第二信号线202的电压不为零，则主机板200为开机状态，处理电路120会传送关机信号至主机板200，使得主机板200关机(步骤335)。Next, the process of the processing circuit testing the motherboard (step 330) will be described in detail, and please refer to FIG. If the voltage of the second signal line 202 is zero at this time, the main board 200 is in the shutdown state, and the processing circuit 120 will transmit a power-on signal to the main board 200 through the third signal line 203, and the main board 200 will turn on the power-on signal after receiving the power-on signal. Start the program (step 331); if the voltage of the second signal line 202 is not zero at this time, then the main board 200 is in the boot state, and the processing circuit 120 will send a shutdown signal to the main board 200, so that the main board 200 is shut down ( Step 335).

主机板200在进行开机程序的过程中，基本输入/输出系统210会先进行开机自我测试以测试主机板200上的各个周边是否正常，当基本输入/输出系统210开始测试一个周边之前，会通过第一信号线201传送代表此时将要进行何种周边的测试的状态信号至处理电路120，同时处理电路120会计算开机信号传送至主机板200的时间，当处理电路120计算的时间与步骤320所输入的开机时间相同时(步骤333)，处理电路120会将基本输入/输出系统210最后传送过来的信号的值与预定状态值进行比较(步骤334)，若基本输入/输出系统210传送过来的状态信号的值与预定状态值相同，则表示主机板200的开机过程一切正常，处理电路120会将累积检测次数加一，同时会通过第三信号线203传送关机信号至主机板200，并开始计算关机信号传送至主机板200的时间(步骤335)，使主机板200关机以完成当次的测试；若基本输入/输出系统210传送至处理电路120的状态信号的值与预定状态值不同，则处理电路120会产生如“开机失败”的第一错误信号(步骤339a)，并将第一错误信号传送至七段显示器显示(步骤340、步骤350)，同时结束测试。而为了让用户更清楚的得知主机板200在开机的过程的哪一个状态发生错误，因此处理电路120还可以将产生第一错误信号时接收到的状态信号传送至七段显示器显示。处理电路120在传送关机信号至主机板200后，主机板200会进行关机程序以关机(步骤335)，处理电路120会在主机板200关机之后检测主机板200的电压(步骤336)，若电压不为零，表示主机板200关机失败，也就是主机板200还是开机的状态，因此处理电路120会产生如“关机失败”的第二错误信号(步骤339b)，并传送第二错误信号至七段显示器显示(步骤350)，同时停止后续的测试；若电压为零，则表示主机板200成功的关机，处理电路120会判断累积检测次数是否与步骤320所输入的检测次数相同(步骤337)，若相同，则表示主机板200的测试完成，不需再进行测试；若不同，则表示主机板200的测试未完成，需要等待处理电路120计算的关机信号传送至主机板200的时间与步骤320所输入的关机时间相同时，再次通过第三信号线203传送开机信号至主机板200(步骤331)以进行下一次的测试，于是主机板200再次执行开机程序，处理电路120也再次重复步骤331至步骤337以进行测试主机板200是否可正常开关机。如此，本发明即可以提供一种测试主机板开关机是否正常的功能，解决现有技术所提到的问题。During the boot process of the motherboard 200, the BIOS 210 will first perform a boot self-test to test whether each peripheral on the motherboard 200 is normal. Before the BIOS 210 starts to test a peripheral, it will pass The first signal line 201 transmits a status signal representing what kind of peripheral test will be carried out to the processing circuit 120 at this time, and the processing circuit 120 will calculate the time when the power-on signal is transmitted to the motherboard 200, when the time calculated by the processing circuit 120 and step 320 When the input power-on time is the same (step 333), the processing circuit 120 will compare the value of the signal transmitted by the basic input/output system 210 with the predetermined state value (step 334), if the basic input/output system 210 transmits If the value of the status signal is the same as the predetermined status value, it means that the boot process of the motherboard 200 is normal, and the processing circuit 120 will add one to the accumulated detection times, and will transmit a shutdown signal to the motherboard 200 through the third signal line 203 at the same time, and Start counting the time when the shutdown signal is transmitted to the mainboard 200 (step 335), so that the mainboard 200 is shut down to complete the current test; , then the processing circuit 120 will generate a first error signal such as "failed to boot" (step 339a), and transmit the first error signal to the seven-segment display (step 340, step 350), and end the test at the same time. In order to let the user know more clearly which state of the mainboard 200 has an error during the booting process, the processing circuit 120 can also transmit the state signal received when the first error signal is generated to the seven-segment display for display. After the processing circuit 120 transmits the shutdown signal to the mainboard 200, the mainboard 200 will perform a shutdown procedure to shut down (step 335), and the processing circuit 120 will detect the voltage of the mainboard 200 after the mainboard 200 is shut down (step 336). If it is not zero, it means that the mainboard 200 has failed to shut down, that is, the mainboard 200 is still in the boot state, so the processing circuit 120 will generate a second error signal (step 339b) such as "failed to shut down", and send the second error signal to seven The segment display shows (step 350), and stops the subsequent test simultaneously; if the voltage is zero, it means that the motherboard 200 is successfully shut down, and the processing circuit 120 will judge whether the accumulated detection times are identical to the detection times input in step 320 (step 337) , if they are the same, it means that the test of the motherboard 200 is completed, and there is no need to test again; When the power-off time input by 320 is the same, the power-on signal is sent to the mainboard 200 again through the third signal line 203 (step 331) to carry out the next test, so the mainboard 200 executes the power-on procedure again, and the processing circuit 120 also repeats the steps again 331 to step 337 to test whether the motherboard 200 can be turned on and off normally. In this way, the present invention can provide a function of testing whether the power on and off of the motherboard is normal, and solve the problems mentioned in the prior art.

在上述的测试流程中，处理电路120在传送开机信号至主机板200(步骤331)后，还可以加上判断主机板200的电压(步骤332)的步骤，如此可以更快的得知主机板200可否进入开机程序，若电压值符合默认值，也就是主机板200传送至处理电路120的电压值与主机板200工作时的电压相同，则开始计算时间(步骤333)，若电压值不符合默认值，则代表主机板200无法正常的进入开机程序，因此处理电路120会产生如“无法正常开机”的第三错误信号(步骤339c)，并传送第三错误信号至七段显示器显示，同时停止后续的测试。In the above-mentioned test process, after the processing circuit 120 transmits the power-on signal to the motherboard 200 (step 331), it can also add a step of judging the voltage of the motherboard 200 (step 332), so that the motherboard can be known more quickly. 200 whether to enter the boot process, if the voltage value meets the default value, that is, the voltage value transmitted from the motherboard 200 to the processing circuit 120 is the same as the voltage when the motherboard 200 is working, then start counting time (step 333), if the voltage value does not meet The default value means that the motherboard 200 cannot normally enter the boot process, so the processing circuit 120 will generate a third error signal (step 339c) such as "cannot boot normally", and send the third error signal to the seven-segment display for display, and at the same time Stop subsequent tests.

此外，本发明的检测装置100还包含一个电源切换开关190，负责依据处理电路120传送的电源切换信号切换提供给主机板200的电源为直流电或交流电，使得主机板200使用电源切换开关190输出的直流电或交流电进行上述的开机过程。用户在输入开机时间、关机时间、检测次数等参数时(步骤320)，还可以输入一个电源切换时间，使得在测试主机板(步骤330)的过程中，若处理电路120计算的时间与电源切换时间相同时，处理电路120会传送电源切换信号至电源切换开关190，电源切换开关在接收到电源切换信号后，若当时是通过输出直流电提供主机板200的工作电源，则会停止输出直流电，并改以输出交流电，若当时输出交流电则改输出直流电，由此测试主机板在开机过程中切换工作电源的供应来源是否可以维持正常的运作。In addition, the detection device 100 of the present invention also includes a power switching switch 190, which is responsible for switching the power supplied to the motherboard 200 to DC or AC according to the power switching signal transmitted by the processing circuit 120, so that the motherboard 200 uses the power output from the power switching switch 190. Direct current or alternating current carries out above-mentioned start-up process. When the user inputs parameters such as power-on time, power-off time, and detection times (step 320), a power switch time can also be input, so that in the process of testing the motherboard (step 330), if the time calculated by the processing circuit 120 is not equal to the power switch When the time is the same, the processing circuit 120 will transmit the power switching signal to the power switching switch 190. After receiving the power switching signal, the power switching switch will stop outputting DC power if it is providing the working power of the motherboard 200 by outputting DC power at that time, and Change to output AC power, if it is outputting AC power at that time, change to output DC power, so as to test whether the motherboard can maintain normal operation when switching the source of the working power supply during the boot process.
