An already operated flame-detected control system based on telecommunication and self-learning is introduced. Combined with such technologies as computer

communication

automatic control

information processing etc. in this system

the original numerous signal lines are simplified to merely two communication lines

and the self-learning and the remote programming and monitoring functions are added. With the flame-detected control system

the distributed control system (DCS) is optimized

and the data veracity and the reliability of whole system are also improved

thus the maintenance of field detectors becomes easier and simpler.
