Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 2, the double mode change-over switch QH falling in state aware circuit can switch back and forth between indoor mode and door T2 and outdoor pattern and door T3, when end user is when indoor, manual switchover QH switch is to indoor mode and door T2, when outdoor, manual switchover QH switch is to outdoor pattern and door T3, and state aware circuit difference output signal Y1 and Y2 when indoor and outdoors pattern fall.

As shown in Figure 1, indoor warning system and outdoor warning system share the state aware circuit of falling, and the output signal Y1 of state aware circuit and Y2 are connected respectively to indoor warning system and outdoor warning system.Indoor warning system comprises wireless launcher, wireless receiver, calling electronic switch, calling system and loudspeaker; Outdoor warning system comprises loudspeaker alarm module, audio alert module, telephone number display module, GPS locating module and GSM short message communication module, the built-in contact phone number of GSM short message communication module, the position signalling of GPS locating module output can be sent to contact person by note, make rescue personnel know rescue place, the very first time is carried out Quick rescue.

As shown in Figure 3, the wireless launcher in indoor warning system adopts the circuit being comprised of infrared emission chip PT2262 and electronic switch CD4066, and when Y1 is level "0", electronic switch CD4066 is in closure state, and radiating circuit transmits.
