Security gateway carrier plate communication structure based on SOA concept

Abstract

A security gateway carrier plate communication structure based on the SOA concept comprises a gateway carrier plate fixed on a chassis and terminal elements dispersed at all positions of the chassis, the terminal elements are connected with an I / O adapter through cables, the I / O adapter is connected and communicated with the gateway carrier plate through communication cables, and meanwhile, wireless communication modules are arranged on the I / O adapter and the gateway carrier plate. Data in use are rechecked through wireless data while transmission is carried out through wired data and a gateway carrier plate, so that effectiveness and reliability of limited data transmission are checked, a wireless antenna is placed in an automobile cabin, a local wireless network is formed to detect data of a terminal element, and the detection efficiency is improved. In wireless data detection, only one communication chip needs to be used for data conversion in each communication mode through time domain control and distribution, pins occupying a gateway controller are reduced to the minimum through time-sharing connection of the gateway controller, wireless checking is increased, and meanwhile the requirement for hardware can be lowered to the maximum extent.

Description

technical field [0001] The invention relates to the field of intelligent vehicle communication, in particular to a safety gateway carrier board communication structure based on the SOA concept. Background technique [0002] With the development of society, technological progress and people's constant pursuit of green energy, traditional internal combustion locomotives are gradually replaced by new energy vehicles. , information station, local area network and wireless network, more and more new energy car companies are constantly pursuing high response, high power and high efficiency of drive motors, and at the same time integrated the cockpit domain, driving domain, Various intelligent controls such as the chassis domain and the power domain, and these controls depend on and distribute sensors, radars and other electronic components throughout the car body, and the communication modes used by the electronic components are different. The on-vehicle network needs to communic...

AI Technical Summary

Problems solved by technology

[0003] The existing vehicle-mounted gateway products are diverse, meeting the mutual communication between various communication protocols such as Ethernet, CAN, LIN, and TCP / IP. In terms of hardware structure, gateway carrier boards are usually used to lead to multiple I / O gateways. The I / O gateway is connected with various domain control modules, and the domain control modules distributed throughout the car body are connected with the gateway carrier board by using communication cables. Therefore, the intelligent vehicle platform is more inclined to an intelligent electronic product, while the vehicle's The attribute requires that the communication of the electronic product is completely reliable, and the vibration and long-term operation of the car body make the communication cable disconnected, and this risk leads to the downtime of the car body control platform, and the consequences are unpredictable. Therefore, in addition to the perfect Cable production and installation process also requires additional technical support
