The utility model can connect soon and be fixed in indoor dangerous matter sources easily, by detecting distance values between dangerous matter sources and children in real time and comparing with the security value (s) of setting, thus determine that whether children are near dangerous matter sources, and the sound that gives the alarm children are less than safe distance near dangerous matter sources distance time, note to remind adult.The utility model also adopts timing to patrol and examine design, after alarm sends alarm sound signal, if without the reset button that personnel push for emergency on device to scene, alarm sends alarm sound by continuing, and confirms with this children whether having been found that and be in dangerous situation that are grown up.
Accompanying drawing explanation
Fig. 1 is the main TV structure figure of the utility model children dangerous matter sources isolation alarm.
Fig. 2 is the fundamental diagram of the utility model children dangerous matter sources isolation alarm.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, a kind of children's dangerous matter sources isolation alarm, comprise sucker fixed mount 1, distance perspective answers testing circuit plate 2, described distance perspective is answered on testing circuit plate 2 and is welded with near-infrared LED driving group 3, signal threshold values threshold compataror 4, logical gate 5, master controller 6, timing routing inspection circuit 7 and battery 8, described near-infrared LED driving group 3 is integrated with and drives infrared transmission module 9 and drive infrared receiving module 10, described near-infrared LED driving group 3 is connected on described signal threshold values threshold compataror 4, described signal threshold values threshold compataror 4 is connected on described logical gate 5, described logical gate 5 is connected on described master controller 6, described master controller 6 is connected respectively on described timing routing inspection circuit 7 and battery 8.
Described near-infrared LED driving group 3 launches high power red external signal by driving infrared transmission module 9, and by driving infrared receiving module 10 to receive the infrared signal reflected from children's torso, then the infrared signal of reception be converted into voltage signal and be transferred to signal threshold values threshold compataror 4, the threshold threshold voltage that described signal threshold values threshold compataror 4 is fixed by setting, and by and input voltage signal compare, thus determine whether the voltage signal inputted has exceeded the fixed threshold threshold voltage of setting, determine whether the distance of children and dangerous matter sources is less than safe distance with this.The switching value numerical value reverse transfer that described signal threshold values threshold compataror 4 exports by described logical gate 5 is on the interrupting input interface of described master controller 6, when described master controller 6 receives logic low, represent that children and dangerous matter sources distance are less than safe distance, now master controller 6 starts alerting signal.
