Embedded Bus Body Control Network

Presently, since the quickly development of the City time-Bus, the control network system of Bus-body is becoming the focus of automobile electronics. With the rapidly development of embedded software & hardware technology, the concept of the Bus-body control network system is born based on combination with embedded control technology and the CAN-LIN network technology. This paper mainly discusses the Software & Hardware Design of Enbedded Bus-body Control Netwrok System based on LPC2292 microprocessor.Firstly, the paper introduced the condition of the research background and related technologies. The traditional technology of automobile electronics can't meet the requirement of customers, the large-scale application of the Bus-body control system with CAN-LIN network would be the milestone of automobile electronics area.Secondly, the paper described the process of system structure and software & hardware frame design. The system made the LPC2292 as the main microprocessor and used the distributed modules design procedures.Thirdly, the paper expatiated on system software & hardware design in details, the modules were named by functions, such as bridge module, front compartment control module, global control module, bus meter module, manager module, switch module. The paper explained the hardware design of these modules in details, and then illuminated the software design, including device drivers programming design, modules' applications programming design, system setup and analysis programming design.At last, according to the result of the system, the paper summarized the functions and the characteristics of the system, and expected for the system future application and develop direction.
