CAN Bus is some sort of a serial data communication protocol .In this thesis, we design to fulfill a simple and reliable, real-time, remote data transmission program based on the LPC2119 ARM processor with CAN controllers. Outdoor nodes use LPC2119 processor for the control of signal light and the collection of Filament voltage. The data processed conversion to specific agreements data frame through built-in CAN controllers and sent to the bus through 82C250. Data transmission interior to the Centralized management through the bus and display real-time. the management send text and voice alarm when Unusual .Centralized management can also made the information to the bus, to receive and deal after 82C250 processor ,So it can achieve remote control. This article introduces the basic tenets of the CAN bus and transfer agreement, the joint design .It also gives the design and implementation of specific hardware and software.
