Description
Technical field
The utility model relates to a kind of signal converter, specifically a kind of USB/RS232/RJ45 signal converter based on C8051F340 chip.
Background technology
All need to use the conversion between convectional signals at domestic electronic, civil electronic, industrial electronic etc. numerous areas, but be all generally conversion each other between two.Such as: the conversion mutually between two between conversion mutually between two, usb signal and the RJ45 network interface signal between conversion, RJ45 network interface signal and RS232 rs 232 serial interface signal mutually between two between usb signal and RS232 rs 232 serial interface signal.Like this due to signal between two mutually conversion between independence, cause meeting the situation that scene needs multi-signal is changed simultaneously.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of USB/RS232/RJ45 signal converter based on C8051F340 chip, can realize the mutual conversion between any two kinds of signals in usb signal, RS232 rs 232 serial interface signal, three kinds of signals of RJ45 network interface signal, also can realize the conversion of bursting out in real time of all signals.
The utility model is realized with following technical scheme: a kind of USB/RS232/RJ45 signal converter based on C8051F340 chip, comprise the C8051F340 chip of self-carried USB protocol stack, the toggle switch being connected with C8051F340 chip, the USB interface being connected with C8051F340 chip, the Ethernet interface being connected with C8051F340 chip, the RS232 serial line interface being connected with C8051F340 chip, the power transfer module of the connection being connected with C8051F340 chip, power supply is walked around module to C8051F340 chip by power supply, Ethernet interface and the power supply of RS232 serial line interface, described toggle switch is for selecting the mutual conversion between two signals of usb signal, RS232 signal and RJ45 signal.
The beneficial effects of the utility model are: detecting the selection of stirring of toggle switch, judge between corresponding signal and realize mutually and changing, can realize the mutual conversion between any two kinds of signals in three kinds of signals of converter of usb signal, RS232 rs 232 serial interface signal, RJ45 network interface signal, also can realize the conversion of bursting out in real time of all signals.
