| Abstract: | In order to solve the deficiency about intelligent building monitoring system currently,according to the many advantages of CAN bus,the network of intelligent building monitoring system based on CAN-bus is proposed.Starting from the research of CAN2.0B bus specification,the hardware base about CAN bus specification is introduced and CAN-bus message format is analyzed.Through the distribution of packet identifier,the communication protocol for the system is designed and the software design process is given.The arbitration problem in communication process about intelligent building monitoring system is well solved. |
