1344584 IX. Description of the Invention: [Technical Field] The present invention relates to a test method and system, and more particularly to a measurement method and system for replacing manual input. [Prior Art]

In the testing of many computer equipment, it is necessary to quickly, immediately, continuously and accurately capture and measure many related parameters and instant messages, and it is necessary to complete complicated data processing work. Most of these tests are currently done by manual or manual testing. In other words, a large amount of human resources is required for equipment testing. Especially in the testing of new products, a lot of basic parameter testing is needed, which greatly reduces the efficiency of the work. The first picture A is a typical traditional test environment consisting of a test platform 13 spot measuring instrument 14. The test platform 13 is connected to the wheel-in device 12, and the operating platform can be used for the operation of the platform. According to the operation, the operator judges the test wire. For the setting list, it is often possible to receive 13 ^=. Broken_in·(10) Round or multiple data. Hi life is in the process of testing, if the manual or manual test operation is very frequent 0608D-A41551tw-100225·Full version f 5 1344584 Traditional 'usually must have someone The equipment and equipment should be called, and the operation of gambling would form a situation of "people and other equipment," and wasted human resources. However, if the test personnel are required to participate in the testing process of some test items,

As technology advances, some automated test systems are increasingly being used in the above test procedures. As shown in Fig. B, special hardware and software (3) can be added to the test platform 13, and the platform 13 can obtain the measured signal or the amount from the measuring device 14 by the quick connection of the adapters 15 The measuring device 14 measures the data according to the measurement signal. Traditional automated test systems require certain special resident programs (software 133) to be run on test platform 13 combined with special measurement hardware to simulate a realistic operating environment. For example, 'programming the loser who needs the operation of person 1 to

High, and the lack of quality of the operators often leads to "equipment, etc., the problem, reducing the utilization of the commission. Performing software operations to perform; however, some test signals need to be tested during the test" Additional hardware devices will be required to process these tested signals and feed back to the test platform. Therefore, in addition to testing the device under test 131, the test platform 13 needs to receive measurement data and perform test software operations, any of which can be performed. Errors can affect the measurement results, and it is difficult to detect unexpected errors during the test. In summary, the environment simulated by such automatic measurement systems is not the actual real environment. In addition, such automatic measurement systems There are also many restrictions, such as transmission 0608D-A41551 tw· 100225-full version f 6

The system test method can't restart the test platform with the resident program, and then restart the test and level σ. Therefore, manual intervention is inevitable. In the case of manual intervention, the moon-shaped platform will require additional mechanisms to notify the operator to enable the operator to process in time to reduce the situation of “machines, etc.. The platform may also be in the process of testing. In the event of a crash, it is not easy to let the test platform in the state of the machine perform the notification to the operator. Because the test platform is down, all calculations will stop, and the operator will be notified further. Regarding the issue, I would like to make other improvements that require manual intervention to try to avoid "people and other equipment, or "equipment, etc., the 2 shape and the other - aspects" related improvements should also try not to change the test platform. Under the premise of the development of 'cutting down _ flattening needle level or canned platform such work time and cost. [Summary of the content], Xin in the above-mentioned financial scene, in order to meet the needs of certain interests in the industry, this The invention provides an automatic test method and system that can be used to solve the above-mentioned problems of the conventional automatic test method and system. - The purpose is to reduce the participation of human I, the automatic test method and the line improvement of the present invention (4) manual manual quantity and preparation (such as an oscilloscope) 2.
