strong test. That is, to test the ability of the software system to operate normally under abnormal conditions. Strongness has two meanings: fault tolerance;Recovery ability.
Transmitter: The function is to detect process parameters and transmit the measured values in the form of specific signals for display and adjustment.
Composition 1) Measuring instrument: any device used to obtain measurement results.
1. System testing: mainly including functional testing, interface testing, reliability testing, usability testing and performance testing. Functional testing is mainly aimed at testing, including functional usability and functional realization. Regression test: refers to the test activity carried out in the software maintenance stage to detect errors introduced by code modification.
2. System testing can be divided according to different test requirements and test methods.For different test types, including functional test, performance test, security test, compatibility test, installation test, configuration test, etc. Each type of system test has its own specific test objectives and test methods.
3. Strength test, strength test checks the resistance of the program to abnormal situations. Intensity testing always forces the system to run under abnormal resource allocation.
4. The basic content of network system testing mainly includes the following aspects: Functional testing: Verifying whether the functions of the network system meet the expected requirements, including data transmission, protocol interaction, security and other functions.
1. It is mainly composed of four links: controller, controlled object, actuator and transmitter. Controller: The wiring of the main circuit or control circuit and the resistance value in the circuit can be changed in a predetermined order to control the start-up, speed regulation, braking and reverse master command device of the motor.
2. Composition 1) Measuring instrument: any device used to obtain measurement results.
3. Functional test. That is, to test whether the function of the software system is correct, which is based on requirements documents, such as the Product Requirements Specification. Since correctness is the most important quality factor of software, functional testing is indispensable. Strongness test. That is, to test the ability of the software system to operate normally under abnormal conditions.
4. The basic components of general computer measurement systems include sensors, signal conditioners, computers and application software.Since the computer can only process digital signals, the A/D conversion device has become an indispensable link in the computer test system.
The quasi-optical system: The main function of the quasi-optical system is to convert the incident non-parallel light into parallel light and project it onto the dispersion prism.
The photoelectric detection system receives the light radiation of the measured object, converts the received light radiation into electrical signals through the photoelectric detection device, and then extracts useful information through the electrical signal conditioning circuit such as amplification and filtering. After digital-to-analog conversion, it is input into the computer for processing, and finally displays and outputs the required detection physics. Quantity and other parameters.
Quality inspection: photoelectricitySensors can detect the size, shape, surface characteristics and other physical properties of various materials and products, including size sorting, channel width detection, object classification, etc. Especially for small parts or parts with special shapes, it is very effective to use photoelectric sensors for accurate measurement.
Optical detectors can be divided into various types according to their materials and structures, including photodiodes, photomultipliers, photovoltaic cells, phototransistors, PIN photodiodes, etc. Among them, photodiode is the most commonly used one. Its structure is similar to that of ordinary diodes and is composed of p-n structure.
1. The system is mainly composed of three parts: test vehicles, road simulation equipment and data acquisition and analysis system.Test vehicle: Test vehicle refers to the car to be tested, which is usually equipped with sensors, measuring devices and other equipment to record various data during the operation of the car.
2. Road simulation system: hydraulic or electric system is used to generate vibrations of vehicle movement to simulate different road conditions. For example: braking, acceleration, sharp turns, undulating sections, etc.
3. Control system: The control system is the main part of the chassis power tester, including electronic controllers, computers, sensors and data acquisition systems. These components work together to measure the performance of the vehicle under different loads, including engine power, torque and tire rolling resistance.
4. Composition 1) Measuring instrument: any device used to obtain measurement results.
5. After multiplication or synthesis, input into the test bench control system, you can obtain any reinforcement multiple or any different road surface synthesis to carry out accelerated simulation tests.
