有人有关于The development of CAN bus的英文文章么?中文的也可以 求5000+字数以上的

Answer 1

Abstract—A special Controller Area Network (CAN) bus
application layer protocol is designed for the high reliable and
high real-time control network of the beam control system.In
this paper,messages on the network are classified and the
identifier coding,data coding,network management
mechanism and physical interface are defined.Then network
load analysis for the real-time control network is introduced.
At last a test platform based on CAN bus for the beam control
system is built to validate the design.Experiment results
indicate that the developed CAN control network for the beam
control system is very reliable and has good real-time
performance and low network load rate.

I.INTRODUCTION
The beam control system can control antenna beam to
desired spatial orientation.Due to the ability of antenna
beam's rapid scanning,the beam control system needs a
high reliable and high real-time control network
[1]
.CAN
bus is a serial communications protocol which efficiently
supports distributed real-time control with a very high level
of reliability.So CAN bus can meet control requirements of
the beam control system.But CAN protocol only comprise
physical layer and data link layer,not application layer
[2-4]
.
Therefore,the application layer protocol can be self-defined,or a standard protocol of international organization such as
CANOpen or SAE J1939 is chosen for the specific system.
The two standard protocols don’t fit for the high reliable
and high real-time control network because of their
complex structures.A simple and practical CAN
application layer protocol which can meet control
requirements of the beam control system is designed,based
on the study of CAN 2.0B standard and the reference of
CANOpen specifications
[4-5]
.
II.ARCHITECTURE OF CAN CONTROL
NETWORK
The CAN control network of the beam control system,
illustrated in figure 1,comprises a master computer and a
number of slaves.The master computer,an industrial PC,is
connected into the CAN control network via a PCI to CAN
adapter.The slave which is a DSP2812 system has a CAN
bus interface.A slave can control a number of antenna
elements.
The master (short for master computer) receives control commands or control parameters via human machine
interface,and then packages and sends a broadcast message
to all the salves.The master also needs to send a point to
point configuration parameters message to the slave.In
addition,the master has other functions such as the network
management,fault diagnosis and information display.
