Abstract
A downhole system including a gun string configured to be deployed into a wellbore, the gun string including plural gun assemblies. A detonator block attached to a given gun assembly of the plural gun assemblies. The detonator block includes a switch assembly. The switch assembly includes a communication unit (CU) configured to receive, from an external controller, a fire command to activate a detonator associated with the detonator block, a measuring unit configured to measure a parameter (V) at the switch assembly, and a computing core (CC) configured to locally make a decision whether to activate or not the detonator, after the fire command is received from the external controller, based on whether a voltage measured by the measuring unit at the switch assembly is larger or not than a threshold voltage.
