6. The automatic alarm device for household gas leakage according to claim 5, characterized in that: further comprising:
the life time calculation module (25) is provided with a first distress time threshold value of the life safety state of the standing personnel in advance and a second distress time threshold value of the life danger state of the standing personnel in advance, and is coupled with the information feedback module and used for calculating the time of the property personnel moving to the owner address with the fuel gas leakage when the property personnel receives the notification from the static human body alarm unit (16) after the information feedback module feeds back the notification to the property personnel;
and the notification conversion module (26) is coupled with the time calculation unit, and when the time calculated by the time calculation unit reaches a first distress time threshold value and the position of the property personnel does not coincide with the owner address with gas leakage, other residual property personnel mobile phone numbers in the working state are selected by the property personnel working state mobile phone number database (17) to carry out voice notification of indoor gas dangerous leakage and person standing, and the voice notification is carried out on a second distress time threshold value and the information that the current standing personnel misses the first distress time threshold value.
7. The automatic alarm device for household gas leakage according to claim 6, characterized in that: further comprising:
the property personnel speed calculation module (27) is coupled to the notification conversion module (26) and calculates the movement speed of the notified other remaining property personnel in the working state to the owner address of the gas leakage in real time according to the distance positioning unit (23) and the life time calculation module (25);
the preparation time calculation module (28) is coupled to the property personnel speed calculation module (27) and calculates the time for other remaining property personnel in the working state to reach the owner address of the gas leakage in real time according to the movement speed of the other remaining property personnel in the working state and the positioning distance of the distance positioning unit (23);
and the outdoor alarm module (29) is coupled with the preparation time calculation module (28) and starts an outdoor high-decibel alarm of the gas leakage owner address when the time that other remaining property personnel in the working state reach the gas leakage owner address is less than a second distress time threshold value.
