ORDNANCE FIRING SYSTEM

摘要

An ordnance system of the present invention may include or feature any one or more of: a control unit, one or more effectors (detonators, initiators, shaped charges and the like), and a two-,three- or four-wire communication bus between the control unit and the effectors; and addressable system in which all the effectors can be connected to the same communication bus and the control unit can issue coded signals on the bus addressed to a specific effector; inductive coupling between the effectors and the communication bus; and a multi-voltage level communication system in which communication signals are carried at a first voltage and arming signals are provided at a second, higher voltage. Other features may include two-way communication between effectors and the control unit and the de-centralization of firing control so that the control unit does not have exclusive control over whether the effectors function. As a result, the individual effects possess decision-making ability and, for purposes of the invention, may be referred to as "intelligent" effectors. To participate in the decision-making process, effects of this invention may be equipped with sensors or other diagnostic circuitry whose condition is checked for satisfactory output before functioning is permitted to occur.
