Abstract:
In a weapons system in which a round having a case is fired from a gun, the round including a fuze processor, the round further including a firing circuit having a resistor and also having two contacts in the case of the round, the gun having two contacts which contact the two contacts of the round when the round is in the gun and ready to fire, the gun being fired by applying a voltage in excess of a certain threshold to the contacts of the round via the contacts of the gun, the weapons system including a fire control system outside the gun:a data exchange system for exchanging data between the fuze processor and the fire control system, comprising:(a) an electrical connection, within the round, between the contacts of the round and the fuze processor, the resistor being thereby connected in parallel with the fuze processor; and(b) a data exchange link, between the fire control system and the contacts of the gun, for applying, to the contacts of the gun, electrical signals representative of data transferred from the fire control system to the fuze processor and for receiving, from the contacts of the gun, electrical signals representative of data transferred from the fuze processor to the fire control system.
