The application provides a kind of LTP pressure test monitoring early warning test method, belong to operating system test verification field, the application can guarantee that pressure test reaches standard value and is full load stable operation in time monitoring by monitoring early warning mechanism and pressurization, reaches final test purpose;Through the monitoring early warning mechanism, the running situation of pressure test is monitored in time, the scene of excessively high CPU utilization is monitored in time and early warning information is thrown, the time of abnormal scene occurrence and CPU utilization abnormal value are recorded, so as to notify tester in time for timely analysis, positioning problem in the abnormal CPU utilization of later period.

The utility model discloses a kind of safety valve individual test equipment, belong to safety valve detection technical field, including setting oil tank, test pump and safety valve to be measured, the oil outlet of oil tank is connected by first pipeline with the import of test pump intercommunication, the outlet of test pump is connected by second pipeline with the import of three-way pipe fitting;The first outlet of three-way pipe fitting is connected by third pipeline with the import of safety valve to be measured intercommunication, the outlet of safety valve to be measured is connected by fourth pipeline with the oil return flange of oil tank intercommunication, forms test loop;The second outlet of three-way pipe fitting is connected by fifth pipeline with the oil return port of oil tank intercommunication, forms oil return empty path;Switching valve assembly for oil return empty path and test loop switching is provided on three-way pipe fitting.The utility model has realized the operability of safety valve individual test, with the advantage that flexibility is high, meet the test demand of DV and DS series structure safety valve.

The utility model relates to the technical field of automation equipment, and discloses a chip sorting machine, which is characterized in that a first photoelectric sensing module is additionally arranged and is designed to directly face a placement position, so that the placement state of a chip can be monitored, that is, when no chip is detected on the placement position or the chip is obliquely placed, a sensing signal is sent out; therefore, corresponding correction measures can be taken in time. The design ensures the accuracy and reliability of the test process, effectively avoids test failure, blanking failure or chip damage caused by chip omission or improper placement, and is beneficial to smooth proceeding of the test process and stable improvement of product quality.

The application relates to a customized commodity return data construction method and device, equipment and medium, relates to the technical field of computer data processing, and can be applied to the fields of finance and medicine, and comprises the following steps: extracting structured commodity information of commodity table data uploaded by a user based on a customized commodity information table template, creating a customized commodity according to the commodity information, executing automatic shelving or unshelving operations of the customized commodity, and setting corresponding commodity inventories; reading commodity information of the imported customized commodity, assembling the commodity information into specific request parameters, and sending the request parameters to corresponding internal and external systems to complete automatic return of the commodity information. According to the application, the manual chain operation is reduced, the overall time is shortened, the work efficiency is improved, the probability of problems such as data entry errors and configuration omissions is reduced, a large amount of time consumed by repeated problem checking is avoided, and the overall work efficiency is further improved.

A vertical hybrid probe card alignment deviation calculation method and system, the calculation method is characterized in that a coordinate system is established with the probe width direction as X, the thickness direction as Y and the axial length direction as Z;The method comprises the following steps: S1, establishing a projection alignment geometry model of the probe in the XOZ plane and the YOZ plane;S2, based on the geometric relationship, the inclination angle θ of the probe in the corresponding plane is calculated according to formula (1):S3, the inclination angle θ calculated in step S2 is substituted into formula (2), and the offset ΔS of the center of the probe end face relative to the center of the corresponding lower guide plate hole is calculated.

The application provides a test method and device. The method comprises: obtaining a contract file; parsing the contract file to determine a dynamic calculation expression contained in a field value for representing a test interface and a field value for representing a test parameter in the contract file; executing the dynamic calculation expression to determine the test parameter and the test interface; and testing the test interface based on the test parameter to obtain a test result, so as to realize dynamic testing on the test interface.
