Abstract
Abstract The present invention provides a device for distributing electric energy between a current source and several groups of electric current consumers or peripherals P 1 , P 2 . . . P n which is more particularly intended to be placed on board a motorized land, air or sea vehicle and comprises at least a first conductor for conveying the electric energy supplying the current consumers, at least a second conductor for conveying electric control signals and/or receiving information about the state of the current consumers, and at least one central control unit U 1 comprising means for transmitting, receiving, storing and processing coded information for controlling the start up or shut down of the current consumers. In this device, each group of current consumers or peripherals comprise the same microprocessor or programmed means, with the same program and an address recognition circuit associated with this microprogrammed means allowing this latter to recognize itself.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
A device for distributing electrical energy, particularly in vehicles, from a current source to a multiplicity of peripherals electrically connected to said source, said device comprising: a central control unit provided with means for transmitting, receiving, storing and processing coded information for controlling the startup and shutdown of current controllers of said peripherals; a coded information bus connected to said central control unit; and a peripheral circuit for each of said peripherals, each of said peripheral circuits including microprogrammed means programmed with subprograms for each of said peripherals and identical to those of the other microprogrammed means of the other peripheral circuits at respective addresses so that each of the microprogrammed means have identical sets of said subprograms for each of said peripherals, and with an address recognition circuit responsive to coded information received from said bus for identifying the coded information for each particular peripheral circuit and then addressing a specific one of said subprograms to be carried out at the particular peripheral circuit for controlling the operation of a respective current controller.
Claim 2
Independent Claim
174 words
A device for distributing electrical energy, particularly in vehicles, from a current source to a multiplicity of peripherals electrically connected to said source, said device comprising: a central control unit provided with means for transmitting, receiving, storing and processing coded information for controlling the startup and shutdown of current controllers of said peripherals; a coded information bus connected to said central control unit; and a peripheral circuit for each of said peripherals, each of said peripheral circuits including microprogrammed means programmed with subprograms for each of said peripherals and identical to those of the other microprogrammed means of the other peripheral circuits at respective addresses so that each of the microprogrammed means have identical sets of said subprograms for each of said peripherals, and with an address recognition circuit responsive to coded information received from said bus for identifying the coded information for each particular peripheral circuit and then addressing a specific one of said subprograms to be carried out at the particular peripheral circuit for controlling the operation of a respective current controller.
Claim 3
Independent Claim
195 words
A device for distributing electrical energy, particularly in vehicles, from a current source to a plurality of peripherals electrically connected to said source, said device comprising: a central control unit provided with means for transmitting, receiving, storing and processing coded information for controlling the startup and shutdown of current controllers of said peripherals; a coded information bus connected to said central control unit; and a peripheral circuit for each of said peripherals, each of said peripheral circuits including microprogrammed means programmed with subprograms for each of said peripherals and identical to those of the other microprogrammed means of the other peripheral circuits at respective addresses, and with an address recognition circuit responsive to coded information received from said bus for identifying the coded information for each particular peripheral circuit and then addressing a specific one of said subprograms to be carried out at the particular peripheral circuit for controlling the operation of a respective current controller, the address recognition circuits comprising a control flip flop, a wired binary combination and a channel switch which is controlled by the flip flop for transmitting to the microprogrammed means a binary code given by the wired binary combination.
