A communications processing section in a managing device transmits a request for a transmission of generated power quantity information via the Internet to an electric power generator to be managed. A database manager in the managing device stores the generated power quantity information transmitted back from the electric power generator into a database. A timing controller in the managing device controls so that the number of electric power generators to which a transmission request is being transmitted does not exceed a predetermined value.

The present invention comprises systems and methods related to monitoring of energy usage on a power line. In a preferred embodiment, this system comprises (a) an electronic microprocessor-controlled digital electricity metering device coupled to the power line and comprising a non-volatile non-battery-powered data-storage device, wherein the metering device is capable of interval metering and of receiving a data request and transmitting data in response to the request over the power line; and (b) a data collector (preferably, a transponder) coupled to the metering device via the power line. The data collector is preferably capable of (i) receiving data from and transmitting data to the metering device over the power line, (ii) storing data received from the metering device over the power line, and (iii) receiving data from and transmitting data to a remotely located computer (preferably, a billing computer).
摘要:
A power lock device for safe power output/input is a control lock composed of coding devices, decoding devices and electromagnetic switches. The coded signal will attach to the power transmitting line and keeps on transmitting. After discerning that the coded signal is correct, the decoding device turns on electromagnetic switches and conducts power to transmit. If the code is not correct, the decoding device uses the electromagnetic switches to cut off power and achieves the function of power control.

A unit is attached to a refrigeration appliance, such as a freezer, or refrigerator, to alert the user of a sensed condition within the appliance that food spoilage may occur. The unit can monitor temperature within the compartment and determine how long until food spoilage occurs. The unit also can alert a user, monitoring service, or call a repairperson. The unit may be retrofit into existing appliances.
摘要:
A method and apparatus for detecting signals transmitted via a power line to a node which have a source address portion equal to the predetermined address of an electrical metering device, but which were not transmitted by the metering device. Each electrical metering device of a power line communications system has a predetermined address and may monitor the source address portions of signals transmitted via the power lines. The electrical metering device thus detects or flags a power line signal if the source address portion of the transmitted signal matches the predetermined address of the electrical metering device. The electrical metering device may also count the signals having source address portions which match the predetermined address of the electrical metering device. Alternatively, the electrical metering device may transmit a predetermined message on the power lines if a signal is transmitted which has a source address portion which matches the predetermined address of the electrical metering device.

A network for providing sensing, communications and control is described. A plurality of intelligent cells each of which comprises an integrated circuit having a processor and input/output section are coupled to the network. Each of the programmable cells receives when manufactured a unique identification number (48 bits) which remains permanently within the cell. The cells can be coupled to different media such as power lines, twisted, pair, radio frequency, infrared ultrasonic, optical coaxial, etc., to form a network. The preferred embodiment of the cell includes a multiprocessor and multiple I/O subsections where any of the processors can communicate with any of the I/O subsections. This permits the continual execution of a program without potential interruptions caused by interfacing with the I/O section. The I/O section includes programmable A-to-D and programmable D-to-A converters as well as other circuits for other modes of operation.
摘要:
A data transmission system including a pair of parallel transmission lines, applies data signals to the transmission lines through a transformer and an associated impedance connected across the lines. The transformer is magnetically coupled to at least one of the lines to apply a signal current thereto. The signal current is transferred to the other line through the impedance. The impedance is tuned to the transmission frequency so that it has a very low value during data transmission.
