Description

TECHNICAL FIELD

[0001] The present application relates to the field of computer peripheral interface testing, in particular to a computer peripheral interface testing device. BACKGROUND

[0002] The computer peripheral interface is a bridge for data exchange and communication between the computer and external devices. The peripheral interface is a logic circuit for connecting the CPU, memory and peripheral devices of the computer, or two peripheral devices, or two machines through the system bus. It is a relay station for information exchange between the CPU and the outside world. The basic functions of the peripheral interface are: 1. Selecting peripheral devices for information transmission operation; 2. Exchanging information between the selected peripheral device and the host computer, ensuring that the peripheral device sends or receives information in the form required by the computer system characteristics; The interface is composed of interface circuit, connection cable and interface software. The peripheral interface plays a bridge role between the microcomputer and the peripheral device, and has the following functions:

[0003] 1. Addressing function: selecting one of the multiple I / O interfaces;

[0004] 2. Data storage and buffering function;

[0005] 3. Data conversion function;

[0006] 4. Contact function;

[0007] 5. Interrupt management or DMA management function;

[0008] 6. Command control.

[0009] Among them, the Universal Serial Bus (USB) interface is a new peripheral device interface introduced in recent years. It is a high-speed communication interface, and its performance is better than the standard serial interface and parallel interface used by the system.

[0010] When detecting the USB interface, multiple plugging and unplugging are required in a short time, which will cause the temperature of the USB interface to rise. Under the action of thermal expansion and contraction, the USB interface will deform slightly, affecting the plugging and unplugging detection results. When connecting the newer USB connector and interface, the USB connector and interface are not worn, and the friction is larger when plugging and unplugging. When detecting the interface connection, it is more laborious to plug and unplug. Correspondingly, when connecting the older USB connector and interface, the USB connector and interface are severely worn, and the friction is smaller when plugging and unplugging. When detecting the interface connection, it is easy to connect unstably, and the USB connector falls off.
