摘要：
A method for controlling a target switch assembly in a chain of switch assemblies includes distributing the chain of switch assemblies in a wellbore; placing a controller at a head of the wellbore; making a first decision, at the controller, to actuate a corresponding detonator of the target switch assembly; transmitting, from the controller to the target switch assembly, a fire command to activate the corresponding detonator; and making a second decision, locally, at the target switch assembly, to activate the detonator, after the fire command from the controller is received.
