Abstract

The invention discloses a data conversion experimental platform. A core data conversion module is used for conversing controller area network (CAN) bus data and universal serial bus (USB) bus data, a liquid crystal display (LCD) expansion interface module is used for being connected with a LCD displayer, a joint test action group (JTAG) debugging interface module conduct online configuration and debugging the core data conversion module, a USB data interface module transforms USB serial format data into a parallel data format and transforms the parallel data format which is output by the core data conversion module into the USB serial data format, an actuator sensor configuration interface module configurates the core data conversion module and stores configuration information, a microprogrammed control unit (MCU) expansion interface module expands functions of the core data conversion module, and a recommended standard (RS)-232 interface module is a data transmission interface which supports RS-232 communication protocols. The data conversion experimental platform conducts mutual conversion of the USB data and the CAN bus data, conducts online configuration of CAN bus parameters, and detects CAN bus system transmission data timely.

Description

technical field [0001] The invention belongs to the technical fields of industrial control and automobile electronics, and in particular relates to a data conversion experiment platform. Background technique [0002] CAN bus was originally used for internal communication of automobiles. Due to its high performance, high reliability and unique design, it is no longer limited to the field of automobiles. It has been widely used in automation fields from high-speed networks to low-cost multi-tasking networks. Become one of the most promising fieldbus. [0003] The transmission distance of the CAN bus can reach 1 km, and the maximum transmission speed can reach 1 Mbps. When the CAN bus network is connected to the computer, if the RS232 interface is used, the advantage of the fast speed of CAN is limited. To make full use of the performance of the CAN network, the CAN / PCI board can be used, but the cost of the board is high and the development cycle is long. With the developmen...
