消防工程是指一些重要建筑和设施中的自动报警、灭火、防火系统的设计、安装、调试和维修。消防工程系统包括火灾探测报警装置、灭火装置、防火装置等。火灾探测报警装置有感温、感烟、感光式探测器、复合式探测器、可燃气体探测器和其它型式的探测器。灭火装置有水、卤代烷、二氧化碳、泡沫、干粉等分别组成的系统。防火装置有防火门、防火卷帘、排烟管道、排烟阀、排烟口等。此外,还有紧急情况下的安全疏散梯等。设计人员运用系统论、控制论和消防工程理论,根据保护对象的防火要求,对该系统所用的仪 Fire engineering refers to some important buildings and facilities in the automatic alarm, fire extinguishing, fire protection system design, installation, commissioning and maintenance. Fire engineering systems include fire detection and alarm devices, fire extinguishing devices, fire protection devices. Fire detection and alarm device with temperature, smoke, photosensitive detectors, composite detectors, combustible gas detectors and other types of detectors. Fire extinguishing devices have water, alkyl halides, carbon dioxide, foam, dry powder, respectively, composed of the system. Fire safety devices have fire doors, fire shutter, exhaust pipe, exhaust valve, exhaust port and so on. In addition, there are emergency evacuation stairs. Designers use system theory, cybernetics and fire engineering theory, according to the fire protection requirements of the object, the system used by the instrument
