| Abstract: | Fire alarm system is gradually developing with the network and intelligence.Introduced a fire alarm system with many point measurement.The digital temperature sensor is a detector.Single-chip microcomputer AT89C51 is the core of data processing.PC is the monitoring and control system as the upper level.9 bytes data that is read from scratchpad memory of temperature sensor was illustrated in details.The data format and data processing of temperature were described.In order to realize the temperature measurement,the program procedure was expounded.Fire alarm system connection figure and temperature display on the LCD were given out.The fire alarm system has good expansibility and network is easily constructed. |
