Abstract

The invention belongs to the technical field of car electric control, and particularly relates to an interface converting circuit based on an AMT system. The interface converting circuit based on the AMT system comprises a main control panel of the AMT system, a shell and a display system circuit board of an OLED display screen, a RS-232 interface, a converting circuit and an MICROUSB interface, wherein the RS-232 interface, the converting circuit and the MICROUSB interface are connected in sequence. The RS-232 interface is located on the main control panel of the AMT system, the MICROUSB interface is located on the shell of the OLED display screen, and the converting circuit is located on the display system circuit board. The interface converting circuit based on the AMT system integrates a circuit board used for converting the MICROUSB interface to the RS-232 interface into the display system circuit board of the AMT system, and does not need to particularly carry an interface converting wire. The MICROUSB interface is located on the position, very close to the MICROUSB interface commonly used by a computer, of the shell of the display screen, use is very convenient, and finding and using are easy.

Description

A kind of interface conversion circuit based on AMT system
Technical field
The invention belongs to automobile electrically-controlled technical field, be specifically related to a kind of interface conversion circuit based on AMT system.
Background technology
RS-232 interface is EIA EIA(Electronic Industry Association) a kind of serial physical interface standards of formulating.Existing notebook, little with RS-232 interface, but all with MICRO USB interface.The circuit board monitoring or installation with RS-232 interface are downloaded and generally all adopts interface conversion line in outside, cause so all needing at any time to carry a conversion line, very inconvenient.
Summary of the invention
The object of the invention is to overcome MICRO USB interface in prior art and turn the problem that RS-232 interface needs to carry interface conversion line.
For this reason, the invention provides a kind of interface conversion circuit based on AMT system, comprise the master control borad of AMT system and housing, the display system circuit board of OLED display screen, and connect RS-232 interface successively, change-over circuit, MICRO USB interface, described RS-232 interface is positioned at AMT system master control borad, MICRO USB interface is positioned on the housing of OLED display screen, and change-over circuit is positioned on display system circuit board.
Above-mentioned change-over circuit adopts FT232 chip.
Beneficial effect of the present invention: this interface conversion circuit based on AMT system provided by the invention, comprise the master control borad of AMT system and the housing of OLED display screen, display system circuit board, and connect RS-232 interface successively, change-over circuit, MICRO USB interface, described RS-232 interface is positioned at AMT system master control borad, MICRO USB interface is positioned on the housing of OLED display screen, change-over circuit is positioned on display system circuit board, should based on the interface conversion circuit of AMT system, the circuit board of MICRO USB interface conversion RS-232 interface is integrated into the display system circuit board of AMT system, do not need to carry interface conversion line especially again, adopt MICRO USB interface, can general this data line, do not need to prepare new data line again.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is interface conversion circuit schematic diagram.
Fig. 2 is interface conversion circuit and display system schematics.
Embodiment
Embodiment one:
A kind of interface conversion circuit based on AMT system as shown in Figure 1 and Figure 2, comprise the master control borad of AMT system and housing, the display system circuit board of OLED display screen, and connect RS-232 interface successively, change-over circuit, MICRO USB interface, it is characterized in that: described RS-232 interface is positioned at AMT system master control borad, MICRO USB interface is positioned on the housing of OLED display screen, and change-over circuit is positioned on display system circuit board.
Embodiment two:
Above-mentioned change-over circuit adopts FT232 chip, structure is simple, the probability that low price and this chip technology maturation are made mistakes is almost nil, and this chip occurs that when download program the probability crashing, cannot download is also very low, minimizing restarts, again the possibility downloaded, and the transfer rate that 3Mbps can be provided; Should based on the interface conversion circuit of AMT system, the circuit board of MICRO USB interface conversion RS-232 interface is integrated into AMT system and surveys display system circuit board, do not need to carry interface conversion line especially again, MICRO USB interface is positioned on the housing of display screen, the MICRO USB interface position commonly used with computing machine closely, very convenient like this use, is easy to find use.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
