According to the nature and characteristics of high-rise building fire, this paper introduces the principle of fire detection by using scattered light photoelectric smoke detector in high-rise building, and discusses the working process of automatic control alarm.The smoke detection with delay working process is compared and analyzed Compared with the system without delay working process, the reliability of fire alarm is greatly enhanced.A computer system diagram of automatic alarm system is also developed. The research of fire detection and self-control in high-rise buildings discussed in this paper is of great significance to the fire control system with different building structures and different requirements Controlling alarm system has reference value and socio-economic significance.
