| Abstract: | This paper presents the application of the technology of CAN bus in the distributed fire alarm control system used in the college laboratory. The system uses a single chip microcomputer AT89C51, a CAN controller and a transceiver as a client. A controlled LAN consists of several intelligent fire alarms by CAN bus. Fire alarms integrate with automatic alarm and intelligent alarm. MCS and PC build respectively with GPRS the communication between upper computers and down computers and the telecommunications. The fire alarm system based on the CAN bus overcomes the disadvantage of the active and subordinate communication, in which all the information should be changed via the host. It has many advantages, such as, high reliability and real time in communication. |
