Beschreibung
Zusammenfassung:	The invention discloses a memory type hazardous gas alarm control system. Through introducing a remote monitoring center and a superior valve control device to the memory type hazardous gas alarm control system, the defect that a leakage risk at the rear end of a pipeline valve is prevented by only closing an indoor pipeline valve in the prior art is overcome, and for the leakage at the front end of the pipeline valve, an outdoor pipeline valve is closed only if the concentration of the hazardous gas monitored by the remote monitoring center is up to a preset threshold value, thus, the leakage risk at the front end of the pipeline valve is thoroughly avoided, and the personal and property loss is reduced as much as possible.
