detection circuit

Abstract

The invention provides a detection circuit. The detection circuit comprises a first backboard, a mainboard and a processor. The first backboard is used for enabling a plurality of hard disks to be inserted in the first backboard in a pluggable manner, wherein each hard disk provides an input signal. The mainboard is electrically connected to the first backboard. The mainboard is used for generating a group of judgment signals according to the input signals and a plurality of reference voltages. The processor is electrically connected with the mainboard, and looks for a preset information table according to the group of judgment signals to judge a hard disk type corresponding to one of the hard disks.

Description

technical field [0001] The invention relates to a detection circuit, in particular to a detection circuit for a hard disk type. . Background technique [0002] With the advent of scientific and technological life, computers have already become an indispensable tool in life, and at the same time, the market has higher and higher requirements for computer equipment. A very important item in computer equipment is the server system. Generally speaking, in order to meet market demands, the server system usually must have powerful data processing capability and large storage capacity. In order to meet market demands, it is usually necessary to install multiple hard disks in the server. However, these hard disks may be of different types. Therefore, when multiple hard disks of different types are mixed and matched, it becomes a great challenge and test to distinguish the hard disk type corresponding to each hard disk. Contents of the invention [0003] The detection circuit ...
