when the requirement of the nuisance alarm duration ratio of the alarm system is given, when the nuisance alarm duration ratio does not exceed f, the minimum alarm dead zone value meeting the requirement is calculated and is the optimal value.
7. The safety protection based networking sharing system for large laboratory instruments and equipment as claimed in claim 1, wherein the cloud sharing platform is connected to the internet.
8. The safety protection-based networked sharing system for large laboratory instruments and equipment as claimed in claim 1, wherein the operation end is internally provided with an inquiry module for inquiring the use condition of the instruments and a reservation module for reserving the use time periods of the instruments.
9. The networked sharing system for laboratory large scale instruments and devices based on safety protection as claimed in claim 2, wherein said appointment task assignment module is used for assigning appointment information to a locking module for locking instruments, the reminding module is used for reminding an appointment person, and the timing module is used for recording appointment time.
