Beschreibung
Zusammenfassung:	The invention relates to the technical field of gas leakage control, and particularly discloses a safety control system and method for gas leakage based on monitoring and analysis of the use condition of an indoor gas appliance. The method comprises the following steps: firstly, setting a pressure measuring point at a gas inlet of a gas appliance to obtain gas pressure, and calculating the gas transmission quantity in unit time by combining the diameter of a gas pipeline; secondly, the effective transmission area of a gas outlet of the gas appliance is obtained according to the current opening degree of a valve body of the gas appliance, and then the gas amount consumed by the gas appliance is calculated; and finally, the consumption of each gas appliance is accumulated to obtain a total consumption estimated value, and the total consumption estimated value is compared with the total consumption detected by the gas meter to judge whether leakage exists or not. According to the invention, the gas use state can
