Description

Technical Field

[0001] The present invention relates to a static resistance testing device and a testing method, and in particular to a multi-compatible static resistance automatic testing device and a testing method. Background Art

[0002] Static resistance is the ratio of the voltage across a component (such as a resistor, conductor, or semiconductor) to the current flowing through it under DC or constant voltage / current conditions. This applies to situations where voltage and current do not change over time. For ohmic components (such as ordinary resistors), static resistance is a constant, independent of voltage / current. For nonlinear components like diodes and thermistors, static resistance varies with changes in voltage or current. Static resistance has a wide range of applications in practical circuits and electronic engineering, primarily in areas such as DC circuit analysis and design, component testing and troubleshooting, and power supply and load matching. It is a fundamental tool for circuit design, troubleshooting, and component selection.

[0003] Traditional static resistance test systems use fixed equipment and methods, do not specify the accuracy of static resistance, and are used to test a specific product. They have the disadvantages of single test equipment, poor flexibility, and low reliability. Summary of the Invention

[0004] The purpose of the present invention is to design a multi-compatible static resistor automatic testing device and testing method. By utilizing the compatibility characteristics of the equipment, not only can the equipment resources be effectively utilized, but also the requirements of multi-channel testing and test index reliability can be met. At the same time, the equipment testing cost can be effectively reduced, and the labor cost can also be effectively reduced.

[0005] The technical solution of the present invention is: A multi-compatible static resistance automatic test device, consisting of a test control platform, a static resistance measuring device and a matrix switch; The test control platform centrally manages configuration parameters and various instruments and equipment, and outputs result data and reports; One end of the static resistance measuring device is connected to the matrix switch, and the other end is connected to the test point of the product to be tested. It can be selectively replaced according to different index requirements and connected to the host computer through serial communication (such as Visa, network port, etc.); The matrix switch performs channel switching. The number of matrix switches can be increased as needed. The test points of the product to be tested are connected to the static resistance measurement device, and connected to the host computer through serial communication (such as Visa, network port, etc.); Furthermore, the static resistance measuring device is a multimeter or other equipment capable of collecting static resistance; Furthermore, the test control platform is a host computer, which is mainly composed of a parameter configuration module, an instrument and equipment control module and a data storage module.

[0006] The present invention adopts a multi-compatible static resistor automatic testing device and testing method, which utilizes the compatibility characteristics of equipment, can not only effectively utilize equipment resources, but also meet the requirements of multi-channel testing and test index reliability, and can effectively reduce equipment testing costs and labor costs.
