Description of the invention: [Technical field to which the invention pertains] The autumn-test method and money of the present invention, in particular, a measurement method and system for replacing manual input. [Prior Art] In many computer equipment tests, many relevant parameters and instantaneous messages need to be captured, measured, and measured quickly, instantaneously, continuously, and accurately, and most of them need to be completed by manual or manual testing, in other words. In terms of equipment testing, it takes a lot of manpower. Especially in the testing of new products, a lot of basic parameter testing is needed, which greatly reduces the efficiency of the work. Figure-A is a typical traditional test environment consisting of a test (four) 盥 measuring instrument. The test platform 13 is connected to the input device 12, and is available for the operator to enter the age-old resignation 13 to install (4) the device ΐ3ι, and to perform the duties according to the instructions of the operator. The test signal generated by the job _ is sent to the measuring device 14: The operator can judge the test result by looking at the measuring instrument. For the setup order - by the relay 131 _ test platform η, it may often be necessary to repeatedly type the non-off command and obtain the data one or more times through the above process. 200817859 In the process of testing, if the manual or manual retrieving operation is very frequent, it usually takes a person to wait for the device _ should, in order to carry out the next-stage operation, forming a situation of "human devices," and wasting human resources. Resources. However,: In the test process of some jobs, the operator is required to (4) participate in the high, and the operator's prime f is insufficient, and the record will cause the "equipment, etc." question = reduce the utilization of the device. With the advancement of technology, some self-test systems have been gradually applied to the above test flow. As shown in FIG. B, special hardware and software 133 can be added to the test platform 13, and the test platform 13 The measured signal can be obtained from the measuring device 14 by the connection of the adapters I5 or the measuring data generated by the measuring device μ according to the measured signal. The conventional automatic test system needs to run some special tests on the test platform 13. The resident program (software, 133) 'and combined with special measurement hardware, _ simulates the real operating environment. For example, the input that requires manual operation is programmed to perform software operations to perform; In the course of the test, there are still some measured signals that need to be measured. The hardware equipment required by the target is to distinguish the money measurement signal and give back to the service platform. The ship, Lin ^ 13 needs to be in addition to the equipment under test (3). The measurement of the data and the execution of the test software, any one of the links may affect the frequency result, and the unexpected error caused by the process of reversing. In summary, the environment simulated by such an automated system is not The actual real environment. 200817859 In addition, the automatic measurement of this ^ also has many limitations. For example, the traditional test method can not restart the test platform after the platform is turned over. Therefore, the human slave is not a slave. Can be avoided. In situations where manual intervention is required, the platform will need to add additional personnel - a mechanism to notify the operator 'to enable the operator to process in time to reduce the situation of "machines, etc." However, the test platform may also be in a state of crash during the test. Second, it is not easy for the platform in the down state to perform the action of the operator. Because the test platform is down, all operations will stop, let alone notify the operator. According to the above environment and the problems arising from it, it is obvious that other improvements that require manual intervention are needed to avoid "people and other equipment," or "equipment," and other related aspects of improvement should also be The need to change the premise of the test platform τ development, the time and cost of the work such as the thief's low-level job, the Wei __ test platform. [Invention], in view of the above-mentioned invention background, in order to meet certain industrial interests The present invention provides an automatic test method and a system for solving the above-mentioned conventional automatic test methods and systems that fail to achieve the standard. The present invention aims to reduce the degree of human participation, the automatic test of the present invention 200817859 Ι = Γ, good In the past, it was necessary to manually adjust the measuring equipment (such as an oscilloscope) to test the results of the traditional test method, the test steps were completely simplified, orderly, and have good repeatability. A pure external method is used to flatten any slanting interference to ensure the authenticity of the quantity and fruit. In addition, the present invention adopts computer communication. The wheeling/input interface used therefore controls the software on the computer according to different _ trials. The development system requires time and short, and has good upgradeability and expansion of most computer card electrical performance _ test. Accordingly, one embodiment of the present invention provides a keyboard/mouse simulation & 'can be used with a keyboard or a mouse' or both. And in the present invention, The analog device with the function of the keyboard/mouse simulator is used as the input device of the computer controlled test platform to test the device or software under test with the control gamma platform. Then the measurement platform or the device under test is measured by the measuring device. After the measurement, the measurement data is generated to the computer. The computer can adjust the measurement range according to the quantity of the material. [Embodiment] The invention is directed to an automatic test method and system.

In another preferred embodiment of the present embodiment, the analog device 22 is a keyboard and a mouse simulator, and the keyboard and the mouse simulator can be connected at the same time or partially connected to the input interface or the mouse input interface. 'According to the connected input interface to achieve all or part of the above functions of the keyboard simulator and the mouse simulator, that is, the keyboard and mouse simulator can simulate the keyboard or mouse signal according to the command signal. Figure 2B is a schematic diagram of a keyboard/mouse simulator as described above, including a command signal interface 221, a programmable microcontroller 223, a keyboard/mouse connection 200817859 port, a relay and sampler 227. The command signal interface 221 is configured to receive the command signal 212, and the received command signal 212 is translated into the input signal 222 via the programmable microcontroller and transmitted to the test platform 23. The sampler 227 can be used to receive and reflect the signals fed back by the test platform 23. For example, the test platform 23 can indicate whether the "Num Lock" (numeric key lock function key) on the keyboard is doped by the potential of the feedback signal. As described above, the analog device 22 can receive a command signal 212 from the control computer 21, translate the command signal 212 into an input signal 222, and output it to the input interface of the test platform 23. Accordingly, analog device 22 can have a translation component 221 that translates the command signal 212 described above into an input signal 222. Therefore, the translation component 221 can utilize hardware or software to achieve the above-described translation function. For example, the translation component 221 can utilize a look-up table circuit that outputs an input signal 222 in response to the command signal 212. For example, the translation component 221 can calculate a software. The software uses a lookup table to index the input signal 222 corresponding to the command signal 212. The software and the lookup table can be stored in a storage component. The storage element may be a random access memory, a read-only memory, a firmware, a flash memory, a disk (including a floppy disk or a hard disk), a compact disk or other related electronic storage medium. . In a preferred embodiment of the present embodiment, the above-mentioned table lookup circuit or look-up table may have a plurality of, that is, the translation component 221 has a plurality of look-up tables or look-up tables 11 200817859. The selection mode can be implemented by a switching circuit or command signal 212. For example, the switching circuit can be a multiplexer, and one of the meter reading circuits or the look-up table is selected by the multiplexer. The multiplexer can determine the look-up table or look-up table to be selected by a switch or command signal 212. The switch can be an electronic component of the translation component 221 and can be set by manually setting or commanding the signal 212. In addition, the command signal may include a lookup table code, and the translation component 221 translates the command signal 212 into the input signal 222 according to the lookup circuit or lookup table corresponding to the lookup table code. The command signal 212 described above may be a series of character or mouse command signals. Therefore, in the translation of the command signal and the input signal 222, an input signal can be mapped by a character or a mouse command signal, or can be translated into an input signal or a series of inputs by the series of characters or the mouse command number. Signals, the invention is not limited. Therefore, the input signal 222 received by the analog platform 22 by the analog device 22 is manually operated as a manual operation. The advantage is that the manual input process can be completely replaced by the control computer 21 controlling the analog device 22. In other words, according to the disclosure disclosed in the present specification, the test platform 23 completely avoids the time for the test platform to wait for manual input when performing boot (_), shutdown, system reset, input data, or other related operations. , in turn, can greatly increase work efficiency and avoid delays caused by manual input. The test platform 23 can be used to test a test target, which can be 12 200817859 A device under test 23 - the software to be tested 23 and the software to be tested 233, when received, the device 231, Tian Yicheng I When the software 233 or the device under test 231 and the soft device under test # > , 匕 3 ', and the mode 233 are displayed, the test software 23 23 performs an operation. In addition, the test platform 23 communicates with the device under test 231 by the test platform, system, and student. Furthermore, the software 233 can be a driver or application of the device under test 231. The connection between the device under test 23i and the test platform 23 may be contact or non-contact, that is, the device under test 231 may be connected to the interface provided by the test platform 23 (such as the output/input interface or any bus interface described above). Or communicate with the test platform 23 by wireless transmission. In other words, the condition of the equipment under test and the test platform 23 are noisy, and whether it is contact or non-contact, this is not limited. The bus interface described above may be a PCI bus, an EISA bus, an ISA bus, or a bus of other specifications. During the test, the measuring device 24 measures one or more of the tested signals 232 of the test platform 23 or the device under test 231. The measured signal 232 may be generated by the test platform 23 or may be generated by the device under test 231. Produced. In other words, the measurement device 24 can measure the measured signal from one or more lines of the test platform 23 or the device under test 231. Therefore, the measuring device 24 of the specific embodiment may have one or more, each measuring device 24 can simultaneously measure one or more measured signals 232, and the present invention does not limit the measured signal 232 and the measuring device 24 And the type and quantity of the signal 232 to be measured that can be measured by the single measuring device 24. 13 200817859 The measuring device 24 generates the measuring data 242 according to the measured signal 232, and transmits the measuring data 242 to the control computer 21, and the control computer 21 can issue the command signal 212 according to the measuring data 242 for the next stage of testing. Therefore, the measuring device 24 can measure the signal under test 232 with a probe (PR0BE), a measuring pin, and a non-contact type (such as infrared temperature measurement). Similarly, the connection between the measurement device 24 and the control computer 21 may also be a General Purpose Interface Bus (GPIB) 25^ interface. On the other hand, the connection mode/signal transmission mode of the automatic test system according to this embodiment can also be as shown in the second C diagram. The measuring device 24 can be connected to the control computer 21 through the analog device 22, that is, the above-mentioned universal interface bus 25, or the above-mentioned output input interface or bus interface interface is connected to the analog device 22, and the analog device is responsible for controlling the computer 21 and The communication between the devices is measured as shown in the second C. In addition, the test platform 23 can also communicate with the control computer 21 through the analog device 22, or feed back the measured signal 232 to the control computer 2, and the control computer 21 can also issue a command signal according to the measurement data 242. The measuring device 24 is adjusted based on the measurement data. For example, when the signal under test 232 exceeds the measurement range currently set by the measuring device 24, the control computer 21 can issue an adjustment signal 214 to adjust the setting of the measurement range. Accordingly, another embodiment of the present invention is an automated test method, 200817859 as shown in the third illustration. First, as shown in step 310, a command signal is sent by a computer to an analog device. Then, as shown in step 320, the analog device sends the two input signals to the test platform according to the foregoing command signal. Next, as shown in step 33, the test platform tests a device under test according to the input signal and generates a signal to be tested. Then, as shown in step 340, the measuring device generates the measurement data according to the measured signal and sends it to the computer. Finally, as shown in step 350, the computer analyzes the measurement data and performs the test of the next step. The specific information of the nose machine, the analog device, the test platform, the measuring device and the related signals such as the command signal, the input signal, the measured signal, and the measurement data are as in the previous embodiment. It is not described here with the second A picture or the second c picture. The computer of the second A picture, the second C picture and the third figure may have a software, and the computer performs testing according to the software. Therefore, during the operation of the software, calculating a command signal and adjusting the measurement device according to the software. The above-mentioned soft body spear is an automatic measuring method as shown in still another embodiment of the present invention. Please refer to the fourth figure. First, as shown in step 510, the measurement device and the test platform are initialized to enter the test flow (step 52 to step 6). Then, as shown in step 52, the computer sets the parameter of a digit/analog converter to the test platform through the analog device through the analog device. 'After a delay, as shown in step 53()), the computer then measures the device from the internal device. The voltage of the digital/analog converter is read (as shown in step 54 200817859) and the measurement data is stored (as shown in step 550). After that, increase the parameters of the digital/analog converter (as shown in step 56), and compare whether the measured data exceeds the __ of the measuring device (as in step 57, if the measuring device is not displayed) 'Computer needs & subtraction to measure the weight of the device (as shown in step 580), and wait for a delay time (such as step 5% factory), if there is more than the display of the measurement device Range, check if the maximum value of the measurement is reached (as indicated by Miscellaneous 600), and if the maximum value is manufactured, the test ends. If the maximum value has not been exceeded, repeat the process (steps 520 to 600). It can be known from the above process that the computer sequentially sends a plurality of command messages. After each command signal is sent, the measuring device generates a material corresponding to the command signal, and the computer sends the measurement data corresponding to the command signal. The next command signal. In addition, the computer sends the adjustment signal before the next command signal is sent. For example, the linearity of the analog output DAC of the computer display card is measured by the present invention. The measured physical quantity is the variation characteristic of the output voltage of the three color channels (R, G, b) dac with the input data. According to the above process, the measurement device and the test platform are first initialized, and then the test flow is entered. The ridge computer uses the command signal to set the parameters of a digital/analog converter to the test platform through the analog device. For example, the test process passes through 21G times, and each parameter is incremented by 増 , until the maximum value of the parameter value. The 200817859 test flow, the age/age transition (four) parameters are delayed by 2 seconds in the mosquito system, so that the DAe output voltage is stable 'and multiple sampling to remove the noise (noise) can also allow the computer to have enough time Read the output voltage of the dac from the measuring device 'and store it. 'In the test flow, the computer needs to check the measuring range of the measuring device. 'If the output voltage exceeds the measuring range, the computer needs to send the adjustment signal. Adjust the measuring range of the measuring device to meet the actual needs of the person. After adjusting the measuring device, 'additional delay time is needed to avoid measuring the device yet. The whole test process is carried out. The self-test method and the money improvement of the present invention are improved by (four) manual manual adjustment measuring equipment c such as an oscilloscope) and the traditional test method of the human reward test result, the full step of the job steps It is programmed and has good repeatability. As long as the person prepares the corresponding control program according to the requirements, the entire input process can be fully automated, and no one needs to intervene again, and the degree of labor is reduced. This is a self-contained gamma parameter and can be automatically timed. After the test time is over, it is enough to prevent the result of improper operation or to prevent the result of the test time from being overdue. People, 'only need to connect the analog device to the touch/transport surface of the original test platform, you can use the extra hardware' and do not need to make any modifications to the test bench. You can make full use of the existing equipment. Function to reduce the investment in equipment costs. The traditional self-test system needs to run some special routines on the test platform, which cannot fully simulate the most realistic operating environment. This system is a purely external method that does not introduce any external interference to the test platform to ensure the authenticity of the measurement results. For example, the conventional test method cannot restart the test platform after the test module is closed by the resident program, and the present invention can achieve the operation by the analog device. In addition, the present invention adopts a computer-wide output/input interface, so that the time required to develop the system is short, and has good upgradeability and expandability, and can be used as long as the money is tilted according to different _ silk changes (4). Tested for electrical performance of most computer cards. In the above, the above description _ (four) describes that the present invention may have many modifications and differences.
