5 results about "Test error rate" patented technology

The invention discloses an automatic test method and system for an analog machine, and the method comprises the steps: obtaining a test case selected by a user, and enabling the test case to be obtained by recording the operation of an operator when the operator carries out the manual test of the analog machine in advance; analyzing the selected test case to obtain a monitoring point location selected by an operator when the operator performs a manual test on the analog machine, input operation instructions and timestamps respectively corresponding to the operation instructions; acquiring corresponding monitoring information from the analog machine according to the monitoring point location, sending the operation instruction to the analog machine according to a timestamp corresponding to the operation instruction, and acquiring response information of the operation instruction from the analog machine; and generating a test result according to the monitoring information and the response information. By implementing the technical scheme of the invention, the manual repeated operation is reduced, the test error rate is reduced, and the test efficiency is improved.

The invention provides a submersible pump flow testing device, and particularly relates to the technical field of pump body testing, the submersible pump flow testing device comprises a testing box, a main controller is installed on the outer wall of one side of the testing box, a partition plate is arranged in the middle of the interior of the testing box, a submersible pump to be tested is placed in a water injection area, and a speed detection sensor is used for collecting liquid flow speed data in real time; according to the method, errors caused by a single detection means are effectively reduced, the overall test error rate can be controlled at a low level, the test result is closer to the real flow performance of the submersible pump, meanwhile, due to the visual test box, the liquid level rising situation can be visually seen by testers, and the test efficiency is improved. And the testing intuition is improved, and a surging water flow form is generated in the testing area, so that the liquid surging condition of the submersible pump in real scenes such as rivers and lakes is effectively simulated, and the testing result has higher practical reference value.

The application discloses a kind of TIS fast test methods for multi-probe OTA test system.It includes the following steps: in the process of testing the TIS of first antenna probe, the TIS value of each antenna probe is obtained;And as the estimated EIS value of each antenna probe in the TIS of second antenna probe, the estimated EIS value of first antenna issued by the instrument through antenna probe;According to the difference between the final EIS value of first antenna probe and EIS1, further compensation is obtained to obtain the estimated EIS value data closer to the real EIS, and the EIS of each antenna is obtained according to EIS2 test;According to the EIS of each antenna probe, spherical area integration and average are obtained to final TIS.The application tests the TIS value of first antenna probe first, estimates all antenna probes according to the difference between the estimated EIS value of first antenna probe and the EIS value of second antenna probe, reduces the number of test error rate, improves test efficiency, and improves the test speed of TIS in OTA test.

The invention discloses an efficient corn inbred line combining ability determination field trial design method, which comprises the following steps: S1, field layout design: adopting a chessboard type matrix layout, and planting test seeds and to-be-tested inbred lines in a vertical crossing manner; wherein the n backbone inbred lines serve as test seeds and are planted in rows in the east-west direction, and one test seed is planted in each row; the m to-be-tested excellent inbred lines are planted in a north-south row, and one to-be-tested inbred line is planted in each row; according to the method, the line-column coordinate marks are combined to replace a handwritten label, so that the risks of missing hanging and wrong hanging are eliminated, and the test error rate is reduced by more than or equal to 90%; a test seed and a to-be-tested line are planted adjacently, the pollination path is shortened by 60%-80%, and the single combination pollination time is shortened from 30-40 seconds of a traditional method to 10-15 seconds; after the process is simplified, one person can independently complete pollen collection, pollination and recording, and the labor cost is reduced by 50%; foreign pollen is effectively isolated through the protection line + bagging design, bagging and castration are conducted in time before the to-be-detected line spins and looses pollen, selfing is avoided, and the combining ability measuring accuracy is improved by 95% or above.
