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 field of industrial control and automotive electronics, and particularly relates to a data conversion experiment platform. Background technique [0002] CAN bus was originally used for automotive internal communication. Due to its high performance, high reliability and unique design, it is no longer limited to the automotive field. It is widely used in the field of automation from high-speed networks to low-cost multi-task networks. Become one of the most promising fieldbuses. [0003] The CAN bus has a transmission distance of up to 1 km, and the maximum transmission speed can reach 1Mbps. When the CAN bus network is connected to the computer, if the RS232 interface is used, the advantage of CAN speed is limited. To give full play to the performance of the CAN network, CAN / PCI boards can be used, but the boards are expensive and have a long development cycle. With the development of the USB bus, the bus has gradually ...
