    摘要: A system and method for facilitating smart power meter monitoring are provided. The system for facilitating smart power meter monitoring includes a standards-based frame detector, a CDR, at least one 8b/10 encoder/decoder and data links to receive input signals and transmit output signals. The system provides for the conversion of incoming SerDes signals, like those that may be transmitted from an optical module, into UART signals that can be communicated to the smart power meter directly through a UART port of the meter. The method includes receiving SerDes signals from an optical module and converting the signals to UART signals. The UART signals are converted to comply with industry standard protocols for communication with the smart power meter. The UART signals are then transmitted to the smart power meter through the meter's UART port.

    摘要: A single fiber passive optical network architecture provides utility metering and control functions for residential and commercial customers. A module provides customer termination of the network, the module either replacing or retrofitting to an existing electrical power wall box. This allows the module to not only support communications functions but to use such functions to remote monitor commodity utilities used by the customer.

    摘要: A fiber optic sensor includes a sensor element responsive to a property or condition of a material, such a resistivity, capacitance, inductance, frequency, etc., for providing an output voltage signal that is dependent upon the property or condition of the material. The sensor further includes an optical-to-electrical conversion element, such as a photo detector or a solar cell, that converts an optical signal (photo detector driving optical signal) carried by an optical fiber into an electrical signal. The electrical signal is applied to the sensor element, and in response, the sensor element provides the output electrical signal. The output electrical signal is applied to a measurement device, such as a piezoelectric element, having at least one dimension that varies with changes in the output electrical signal. An optical strain sensor, such as a Bragg grating or Fabry Perot interferometer, is mounted to the measurement device such that changes in the dimension of the measurement device causes changes in the strain of the optical strain sensor. These changes in strain are detected and related to the property or condition of the material. The fiber optic sensor is particularly useful as a resistivity sensor for measuring the resistivity of a fluid. For example, the resistivity of a fluid mixture of oil and water can be measured for determining the relative water and oil content in the fluid mixture. In this configuration, the sensor element includes a pair of spaced apart conductive elements. The output electrical power from the photo detector is applied to the conductive elements and the fluid is passed between the conductive elements. The output voltage from the conductive elements varies in relation to the resistivity of the fluid sample between the conductive elements.

    摘要: The invention provides a monitor for monitoring the condition of fibre optic communication cables. The system employs one or more of the optical fibres of a cable to monitor the cable structure for damage or kinks. By using two separate laser sources and simultaneously monitoring the optical losses at two distinct and separate wavelengths, the loss signature of the monitored fibre is determined, analyzed and related to the mechanical condition of the cable structure. To monitor splice points for moisture, a special optical splice sensor unit detects any penetration of water into the splice and transmits a coded alarm signal over the monitored fibre to the optical receiver. Every splice location is assigned a unique sensor code. The optical splice sensor is driven by moisture detection cell, which forms a single cell water activated battery. Water entering the monitored splice closure wets the tape, which activates the cell. The cell generates sufficient voltage and current to power timing, code generation and modulator circuits in the sensor unit for an extended period of time. The activated circuit drives a modulator which modulates the light travelling down the fibre. The modulated light is monitored at the equipment office and the address of the alarming sensor decoded.

    摘要: A method of transmitting at least two measured values by means of light pulses which are passed by an optical transmitter through an optical transmission path to an optical receiver and whose relative separation in time is proportional to the measured value. The energy consumption for the optical transmission of the measured values is reduced by transmitting needle pulses cyclically, one after another in the same order of succession, in that per measured value an optical measuring pulse is transmitted, whose separation in time from the optical measuring pulse associated with a preceding measured value is proportional the magnitude of the measured value, and in that for each group of measured values an optical identification pulse is transmitted, whose distance in time from a preceding measuring pulse is smaller than the smallest possible distance in time between two successive optical measuring pulses.

    摘要: An improved field instrumentation system employing optical multiplex transmission in which data from a plurality of field devices, including both sensors and controllers, are transmitted through an optical distributor, such as a star coupler, to a master processor at a control panel location as well as to other field devices. The optical distributor branches and couples in a ratio of N:N, the data which are transmitted bidirectionally through the various optical transmission paths connected to the field devices to form the basis of a control loop located in the field. A submaster processor, located in the field and coupled to the optical distributor, is automatically substituted for the master processor in the event that the master processor is disabled. The overall reliability of this system is thereby markedly improved.

    摘要: The industrial installation comprises an active zone (III) with which there are associated means for measurement and for command and a control position (I) separated from the active zone. Means for measurement, for control and for command (15) located in the active zone are supplied with luminous radiations, from the control position, through an optical fibre (8) joining the active zone to the control position. Radiation having a broad spectral band is emitted in the fiber (8) from the control position (I) and then divided in order to obtain unitary radiations for supplying each of the means (15). The invention applies to nuclear reactors.

    摘要: A system for the remote reading of a gas meter includes an interface unit within a domestic residence but situated such that an input/output terminal for the interface unit is accessable from the exterior of the residence, and a hand-held meter reading unit for connection to the terminal in order to read and record the value of the gas consumption indicated by the meter. The meter reading unit has two LED sources, whose outputs are combined a Y-coupler, for passage into the interface unit when an optical fibre is connected thereto. At a multiplexer, the combined beam is dispersed according to wavelength and separately passes along a fibre array to respective roller digits of the tumbler for reflection or not according to the displayed reading. Reflected light passes back through the system, is divided at a Y-coupler and passes to a de-multiplexer such that the light returning in respect of the roller digits can be measured and displayed at a light detector and liquid crystal display.
