power contacts under numeric key 2 key in mobile phone A 5, so, under numeric key 2 key now in mobile phone A 5, two power contacts can be communicated with, be equivalent to people with numeric key 25 second on hand over hand machine A5, because mobile phone A 5 has signal-key dialing function, at this moment, owner is stored in advance in the required telephone number of numeric key 2 in mobile phone A 5 and will dials away, owner's phone is at one's side put through, such owner will recognize combustible gas leakage situation in the very first time, to take next step measure, Chip Microcomputer A 4 from its 17 pin export 5 second low level, after 30 seconds, Chip Microcomputer A 4 from its 16 pin export 1 second low level, the low level exported enters relay K 5 negative power supply input end, so, relay K 5 obtains two normally opened contact end of electric adhesive and closes, due to, two normally opened contact ends of relay K 5 are connected by wire with two power contacts under the switch switch G key in mobile phone A 5, so, under switch switch G key now in mobile phone A 5, two power contacts can be communicated with, be equivalent to people and counted for 1 second with the switch switch G on hand over hand machine A5, so mobile phone A 5 stops dialing, Chip Microcomputer A 4 from its 16 pin export 1 second low level, after interval 1 second, 19 pin of Chip Microcomputer A 4 can export again 5 second low level, after 30 seconds, 18 pin of Chip Microcomputer A 4 can export again 1 second low level, after 1 second, Chip Microcomputer A 4 again from 17 pin export 5 second low level, after 30 seconds, Chip Microcomputer A 4 again from its 16 pin export 1 second low level, constantly circulate with this, in 20 minutes, mobile phone A 5 constantly will circulate and dial two telephone numbers that owner presets, owner's phone is at one's side put through, such owner will recognize combustible gas leakage situation the very first time, to take next step measure, prevent from causing larger accident.
