Abstract
The utility model relates to a vehicle-mounted USB (Universal Serial Bus) communication gateway based on a CAN (Controller Area Network) bus. The vehicle-mounted USB communication gateway comprises a core processor, a CAN controller and a CAN transceiver, wherein the core processor is provided with an SPI (Serial Peripheral Interface), a USB interface, a diode indicator light and a power input port, and connected with the CAN controller through the SPI, the CAN controller is connected with the CAN transceiver, the CAN transceiver is connected with the CAN bus, and the core processor is connected with a USB device through the USB interface. The vehicle-mounted USB communication gateway has the beneficial effects of simple structure, compact layout, small volume, good compatibility, support for hot plugging, higher data transmission speed and stable data transmission.
Description
Technical field
The utility model relates to a kind of vehicle-mounted usb communication gateway based on the CAN bus.
Background technology
At present, the USB transmission technology the use on the vehicle basically also only local on vehicular amusement apparatus, such as the transmission of video display multimedia file.Aspect vehicle control information is transmitted, the transmission platform that also is based on common serial ports that extensively adopts.And serial ports ubiquity poor compatibility, volume are large and do not support the shortcomings such as hot-swappable, and be not ideal enough aspect the efficient of using and convenience.Therefore, should further improve prior art.
The utility model content
The purpose of this utility model provides a kind of vehicle-mounted usb communication gateway based on the CAN bus, to overcome the deficiency of the above-mentioned aspect of existing product.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of vehicle-mounted usb communication gateway based on the CAN bus, comprise core processor, CAN controller and CAN transceiver, described core processor is provided with SPI interface, USB interface, diode indicator light and power supply input port, core processor is connected with the CAN controller by the SPI interface, the CAN controller is connected with the CAN transceiver, the CAN transceiver is connected with the CAN bus, and described core processor is connected with USB device by USB interface.
Preferably, core processor is the CYUSB3014 chip; The CAN controller is the Mcp2515 chip; The CAN transceiver is the TJA1050 chip.
The beneficial effects of the utility model are: simple in structure, compact in design, volume be little, compatible good, support hot plug, has higher data transmission bauds and transfer of data stable.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the described a kind of vehicle-mounted usb communication gateway structured flowchart based on the CAN bus of the utility model embodiment.
Among the figure:
1, core processor; 2, SPI interface; 3, CAN controller; 4, CAN transceiver; 5, CAN bus; 6, power supply input port; 7, diode indicator light; 8, USB interface.
Embodiment
As shown in Figure 1, the described a kind of vehicle-mounted usb communication gateway based on the CAN bus of the utility model embodiment, comprise core processor 1, CAN controller 3 and CAN transceiver 4, described core processor 1 is provided with SPI interface 2, USB interface 8, diode indicator light 7 and power supply input port 6, core processor 1 is connected with CAN controller 3 by SPI interface 2, CAN controller 3 is connected with CAN transceiver 4, CAN transceiver 4 is connected with CAN bus 5, and described core processor 1 is connected with USB device by USB interface 8.
During native system work, TJA1050 can become the CAN data bit flow to all Data Analysis in CAN bus 5 physical channels, and real-time Transmission is to the Mcp2515 chip, the Mcp2515 chip then resolves to CAN Frame (being data link layer packets) to bit stream, and pass through 2 relevant CAN data frame transfer of SPI interface to the CYUSB3014 chip, the CYUSB3014 chip is analyzed the CAN Frame according to the CAN agreement, and convert the usb data bag that meets USB 3.0 agreements to, outwards export the CAN packet by integrated USB3.0 interface at last.
When USB device was connected by USB interface 8 with the utility model, the diode indicator light 7 on the core processor 1 can be indicated the connection status of USB interface 8.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
