Abstract: A communication system uses controllers for bi-directional protocol conversion. There is a plurality of remote signal inputs comprised of supervisory control and data acquisition (SCADA) signals, and/or remote terminal unit (RTU) signals, and/or instrumentation monitoring signals, and/or instrumentation control signals having different protocols. The signals are either in synchronous and asynchronous data formats and include voice inputs. Multiplexing such signal inputs into a composite signal is effected for transmission over electronic and physical communication media using X.25 or higher protocol, at an aggregate transmission data rate of 9.6 Kbps or faster. One or more controller can be configured as the master of remote units. Such units can perform remote signal input emulation; master/remote apparatus emulation, permits user-defined signal port control access; and provides operational diagnostics of the units and their associated communication link.

Abstract: A satellite communication system between a hub terminal and remote terminals simultaneously uses two or more satellites for communication. Rapid signal acquisition for mobile terminals is achieved by incorporation of a Global Positioning System receiver to establish initial frequency and time references. High resolution time distribution is provided by use of spread spectrum coded signals. A combined Time Division Multiple Access/Code Multiplex architecture receives simultaneous signals of widely varying signal strengths. Rapid and numerous changes to the polling sequence is possible. The hub terminal incorporates two high directivity antennas each illuminating a separate geostationary satellite transponder with a spread spectrum coded signal, each orthogonal to the other. The remote terminals employ an antenna of sufficiently small aperture to enable simultaneous reception of both orthogonal transponder signals. Each remote terminal transmits one signal that illuminates both satellite transponders and is received separately by each hub terminal antenna. All transmissions are synchronized to a precision time frame and are spread spectrum encoded. Multiple remote terminals may transmit simultaneously using orthogonal codes. Block addressing reduces the data bandwidth of the hub terminal. The network architecture allows numerous blocks to be established, each block containing any number of remote terminals and each remote terminal may be assigned to be a member numerous blocks. A single command issued by the hub terminal to a particular block, thereby addresses the multiple remote terminals which are members of that block. In order to demodulate the data received from multiple remote terminals, the hub terminal generates a numerical database that fully represents the composite received signal. Iterative digital signal processing is performed in real-time to establish the code phase of each remote terminal. Initial processing of the database demodulates only strong signals. In an iterative manner, the successfully demodulated signals are subtracted from the database and processing is reperformed to extract the weaker signals.

Abstract: An electrical power monitoring and control system including individual sensor modules for mounting directly upon energized electrical power conductors and systems employing such modules, with principal emphasis upon the provision of both data transmitting and receiving means in each sensor module and at an associated ground station. The modules sense the instantaneous values of all parameters necessary to perform complete metering functions and, in one embodiment, are synchronized by a signal transmitted from the ground station and received by all modules so that the values are measured simultaneously on all conductors at a substation. The signals are transmitted by the modules in a time-synchronized manner and are in a condition for use directly by the ground station microprocessor. In another embodiment, data transmissions by a plurality of modules is synchronized to avoid data collisions by self-contained means within each module, requiring no synchronizing signal from the ground station. The modules preferably include a reliable battery back-up system, requiring essentially no removal and/or replacement of batteries for recharging, for providing power to the module electronics when there is little or no current flowing through the associated conductor.

Abstract: A monitoring system using a unique remotely piloted drone with dual counter rotating propellers and carrying electric field sensing, thermal infra-red imaging, video imaging, acoustic and corona discharge sensing equipment. The compact remotely piloted drone flies along a power corridor and is maintained at a fixed distance from an outer phase conductor using on board electric field detection circuitry, video/infra-red imagery and an RF/laser altimeter.The counter rotating, twin-turbo driven configuration for the propellers mounted on coaxial vertical shafts provides a highly stable platform, unlike conventional manned helicopters presently used for routine right-of-way patrols. Dual, counter-rotating saucer-shaped auxiliary propellers provide a degree of stability far superior to a conventional helicopter, particularly in gusty winds. On board sensors and video cameras would permit electric utilities an economic approach to right-of-way monitoring, inspection of frayed conductors or deteriorated splices through infra-red sensing, detection of cracked insulators through acoustic/corona sensors, monitoring of critical, thermally limiting spans and other monitoring functions.
