This invention discloses a sample loading fixture for stress testing, relating to the field of stress testing technology. The invention includes a base plate with several support components mounted on its bottom surface. A slide rail mechanism is fixed to the top of the base plate, and a support assembly and a testing assembly are connected to the top of the slide rail mechanism. The support assembly and the testing assembly are interconnected. A positioning seat is mounted at one end of the top surface of the base plate. A positioning component is provided on one side of the support assembly, and a pressure plate mechanism is provided on the other side. An adjustment mechanism is provided between the testing assembly and the base plate. A position counting component is provided on one side of the slide rail mechanism. This invention, through a stepped planning of the distance the support assembly is pulled, and by comparing the tensile force display of the force gauge and the tensile stress reading of the stress sensor, forms multiple regular test control groups. Coupled with a high-precision testing environment, this enables comprehensive measurement of tensile stress data and completes a comprehensive and accurate recording of the tensile strength of the substrate glass.

This application discloses a data processing method, which includes: performing a stress test on a first application based on a first request volume to obtain a first test result, wherein the first request volume is the concurrent request volume in each time unit of the stress test; determining a first increment based on the first test result; and performing a stress test on the first application based on a second request volume to obtain a second test result, wherein the second request volume is the sum of the first request volume and the first increment. In this way, by determining the concurrent request volume for the next stress test based on the test result of the previous stress test, the problem of inaccurate judgment of the stress test inflection point caused by excessive pressure increase can be effectively avoided, while also solving the problem of excessively long measurement time caused by insufficient pressure increase, thereby improving the efficiency of stress testing.

The application belongs to the technical field of OBU automatic distribution, and relates to an OBU automatic distribution and recovery method, system and equipment, which comprises the following steps: a user initiates a claim or return order containing an OBU type through an ETC applet, and synchronizes to an ETC self-service distribution platform. The platform pre-processes according to the order type: when a claim order, based on the spatial topology perception of the OBU automatic distribution equipment, searches for the storage unit mapped with the OBU type and locks it; when a return order, verifies the warranty information. After user authentication, the platform issues an instruction: claim to open the locked unit to distribute the OBU; return to open the recovery port, and perform multispectral imaging and radio frequency stress testing on the recovered OBU, combine the anti-disassembly switch state to output a state authentication code, and open the mapped unit to replace after verification. The equipment returns the execution result, and the platform updates the order, inventory and life cycle archives. The application realizes the integration of OBU self-service distribution and warranty replacement, and improves the operation efficiency and equipment safety.

The application discloses a pressure decay test method and system based on gas elastic compensation, and relates to the field of sealing pressure test. The method comprises the following steps: connecting a to-be-tested sealed container to a test cavity provided with a gas elastic compensation module, applying a preset pressure test signal first, collecting pressure response and volume change data to identify elastic characteristic parameters of the container; then inflating the test cavity and the container to a target test pressure and entering constant pressure detection, adjusting the compensation amount in real time through pressure feedback control to maintain constant pressure and record the total compensation flow; calculating the theoretical elastic compensation flow based on the elastic characteristic parameters and the real-time pressure, and deducting the total compensation flow to obtain the net compensation flow, thereby determining the leakage rate and comparing it with the integrity standard to realize sealing judgment. Thus, the decoupling of leakage and elastic deformation effect can be realized under the condition of complex elastic structure and small head space, and the detection accuracy and consistency are improved.
