摘要
介绍了CAN总线技术在高校实验室分布式火灾报警控制系统中的应用,设计以单片机AT89C51、CAN控制器、收发器为一个子站,由多个智能火灾报警器通过CAN总线组成的一个控制局域网,火灾报警由自动报警与智能报警结合,单片机、PC机与GPRS分别组成上下位机通信和远程通信.基于CAN总线的火灾报警系统克服了“主从式”通讯中所有信息必须通过主机进行交换的缺点,在通信能力、可靠性、实时性等方面有着极大的优势.
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.
