Interface detection method and device and storage medium

Abstract

The invention provides an interface detection method and device and a storage medium. The method comprises the steps of determining a detection current of a load device according to a to-be-detected interface; wherein the load device is connected with the interface to be tested; detecting the temperature of the load device to determine the real-time temperature of the load device; adjusting a control resistor according to the real-time temperature of the load device and the detection current so as to keep the detection current constant; the control resistor and the load device are connected into a detection circuit; under the condition that the detection current of the load device is kept constant, detecting the to-be-detected interface to determine a detection result corresponding to the to-be-detected interface; by applying the method provided by the embodiment of the invention, the change of the detection current caused by the resistance change of the load device due to the temperature change after the load device is loaded in the process of testing the interface is avoided, so that the test result can better reflect the real test requirement.

Description

technical field [0001] The present disclosure relates to the technical field of interface detection, and in particular, to an interface detection method, device and storage medium. Background technique [0002] With the advent of the modern information society, people's demand for computer products is increasing, and the application of various data transmission and exchange is becoming more and more extensive. Therefore, there are more and more interface devices used to transmit data. In production and life, it is necessary to test the interface to check whether the output of the interface meets the specification requirements under a certain detection current. Usually, a high-power resistor is connected outside the interface for pull-up test. When a certain detection current is performed During the test, select a resistor with corresponding resistance value to connect to the circuit, and measure whether the output voltage of the interface meets the specification requirements...

Problems solved by technology

[0002] With the advent of the modern information society, people's demand for computer products is increasing, and the application of data transmission and exchange is becoming more and more extensive. Therefore, there are more and more interface devices for data transmission. In production and daily life, it is necessary to test the interface to detect whether the output of the interface meets the specification requirements under a certain detection current. Usually, a high-power resistor is connected outside the interface to perform a load test. When a certain detection current During the test, select a resistor with a corresponding resistance value to connect to the circuit, and measure whether the output voltage of the interface meets the specification requirements. However, during the test process, the temperature will rise after the load is loaded, which will cause the detection current to become smaller, which makes the test The results cannot fully reflect the real test needs
