Peripheral device detecting system and its method

Abstract

A detection system of peripheral device is prepared for arranging M numbers of the second lead wires on connection port as each second lead wire being separately corresponded to one of the first lead wires of cable, forming M numbers of the second load wires by grounded second detection load wires, generating voltage signal by responding the first detection lead wire with the second one, using delay circuit to receive voltage signal and outputting delayed voltage signal to electronic unit being used to start up detection on peripheral device.

Description

technical field [0001] The present invention relates to a peripheral device detection system and method thereof, and in particular to a peripheral device detection system and method thereof which allow the electronic device to normally detect the peripheral device each time the peripheral device is connected to the docking station of the electronic device. Background technique [0002] Please refer to FIG. 1A . FIG. 1A is an appearance view of a docking station 1 and a notebook computer (Notebook) 2 in the prior art. For now, although the notebook computer 2 has the convenience of being portable, its function is not as good as that of a desktop computer (Desktop). Therefore, an expansion base (Docking station) 1 has been developed to provide a rich peripheral connection port (Port) of the notebook computer 2, so as to install other peripheral devices (Peripheral devices), such as a printer (Printer), a scanner ( Scanner) and so on. [0003] Please refer to FIG. 1B . FIG. 1...

Problems solved by technology

[0004] However, when the 19th pin of the printer cable and the 19th pin P of the printer connection port 10 19 When in contact, the other leads of the printer cable may not be in full contact with the other leads of the printing connection port 10, so that the printer cannot be detected by the notebook computer 2, resulting in an identification error
