Abstract

The invention discloses a vehicle-mounted comprehensive development platform based on FlexRay. The vehicle-mounted comprehensive development platform based on the FlexRay comprises a power input circuit, a global positioning system (GPS), a general packet radio service (GPRS) wireless data transmission circuit, a digital signal processor (DSP) central controller and a field programmable gate array (FPGA) circuit. The power input circuit is connected with the DSP central controller and the FPGA circuit. The GPS and the GPRS wireless data transmission circuit are connected with the DSP central controller. The DSP central controller is connected with a Nor Flash storage, a serial port communication interface, a controller area network (CAN) communication interface, a FlexRay communication interface, a universal serial bus (USB) communication interface and an external interruption input interface. The DSP central controller is connected with the FPGA circuit. The FPGA circuit is connected with an H bridge output interface, an analog quantity input circuit, a frequency collection circuit, a digital quantity input circuit and a pulse-width modulation (PWM)/digital quantity output circuit. The vehicle-mounted comprehensive development platform based on the FlexRay has the advantages of being simple in structure, low in cost, safe and reliable.

Description

technical field [0001] The invention relates to a vehicle-mounted comprehensive development platform, in particular to a FlexRay-based vehicle-mounted comprehensive development platform. Background technique [0002] The Flexray bus is a bus protocol based on the requirements of the new generation of wire control technology (X-by-Wire). It is a time-triggered bus, but it also supports an event-triggered bus; it has a dual-channel redundant structure; The hardware self-synchronization mechanism meets the needs of real-time systems; the bus utilization rate is high, and 254 bytes of data can be transmitted in one frame; the transmission speed is as high as 20Mbps. [0003] The emergence of the Flexray bus has effectively broken through the limitations of the CAN network and is the development trend of the bus in the future. [0004] With the advancement of science and the development of society, the functions required for civil engineering machinery vehicles or military armor...
