摘要： It is proposed a method for monitoring an electrical power supply line comprised in a seismic cable and extending along the seismic cable. The seismic cable includes: a plurality of seismic sensors arranged along the seismic cable, a plurality of controllers arranged along the seismic cable, and an optical transmission line extending along the seismic cable for carrying data signals from or towards the controllers. The electrical power supply line supplies at least one pair of master and slave controllers. The master controller of a given pair of master and slave controllers performs a step of monitoring a portion of the electrical power supply line between the master and slave controllers, by using an optical loop established on a portion of the optical transmission line between the master and slave controllers, and starting from the master controller and passing through the slave controller.

The light beam is directed along one axis of the fiber. An anisotropic electrooptic material is placed in the zone for receiving the beam from optical fiber and for sending the beam into the fiber. The device further includes an arrangement for analyzing the intensity of the linear wave and a mechanism for determining the variations in the orientation of the linear wave output by phase-shifting means. A quarter-wave plate is inserted between the optical fiber and the crystal, wherein the plate has its axes oriented at substantially 45° to the axes of the optical fiber.

摘要： The present invention is to provide a voltage detector having a common communication line for reducing a manufacturing cost. A low voltage line CPU transmits a detection instruction including an assignment of one address among a plurality of blocks. The detection instruction is branched by a transmitting bus line for concurrently transmitting to a plurality of voltage detector units. When one of the voltage detector units receives the detection instruction with the address being same as a self-address thereof, the voltage detector unit detects output voltages of unit cells and transmits the detected result to the low voltage line CPU. When the received address is not the self-address, the voltage detector unit does not transmit the detected result.
