Abstract:
1. A power ring device in a military vehicle for supplying electrical power to electrical consuming devices of the vehicle, the power ring device comprising: (a) a ring conductor; (b) a plurality of controllers operating as control and switching devices, wherein each controller is connected to the ring conductor and each controller includes a first control unit; (c) a plurality of paired pick ups disposed on the ring conductor, wherein each pair of pick ups connects either an electrical consumer device or an electrical power supply to the ring conductor and to one of the plurality of controllers, wherein a first pair of pick ups of a first controller is connected to a first power supply; and (d) a plurality of current sensor signal lines connecting each control unit of the plurality of controllers so as to form a data connection between the controllers that supervise and control transmission of electrical power along the ring conductor; wherein each controller further comprises: i. a right side and a left side, and each controller includes a right sided switch element and a left sided switch element connected to the control unit and the ring conductor; and ii. a right sided current sensor and a left sided current sensor connected to the ring conductor, to the first control unit, and to the plurality of current sensor signal lines so that a first current value measured by the left sided current sensor of the first controller is transmitted as data to the first control unit of a second controller, wherein each controller includes one pair of pick ups forming a connection to the ring conductor and to a component selected from the group consisting of an electrical consumer, a power supply, and the first power supply, so that the right sided switch element is connected to the ring conductor to the right of the connection, and the left sided switch element is connected to the ring conductor to the left of the connection, and wherein the right sided switch element is connected to the ring conductor between the right sided current sensor and the one pair of pick ups, and the left sided switch element is connected to the ring conductor between the left sided current sensor and the one pair of pick ups.
