摘要:
A communication device is disclosed for communicating telemetry data relating to a fluid, which is passed through a group of concatenated containers such as pipes, tanks and the like in a process installation, to a data processing device. The communication device includes a measuring sensor which can be spatially separated from the data processing device, the measuring sensor having a transponder and a converter for converting a physical variable of the fluid into an electrical variable. The measuring sensor can communicate with a reading device assigned to the data processing device, the measuring sensor being concomitantly loosely guided in the fluid.
摘要:
A method and system by which certain radio transmitters are assigned to certain reception nodes for the purpose of transmitting metering data derived from a plurality of utility meters to a system management computer. The reception nodes are configured to receive and process data transmissions only from those transmitters with data paths assigned to particular reception nodes, and to ignore data transmissions from non-listed transmitters, thereby assuring that on a continuous basis, a majority of the transmitters will utilize only one data path. Lists may be formed for the transmitters and reception nodes in the system management computer and transmitted to the reception nodes. The status of data transmissions through the repeaters may also be uploaded to the system management computer for analysis of data update rates and data path redundancy.

Certain embodiments are directed at methods and systems for transmitting utility usage data using a public switched telephone network (“PSTN”). The methods and systems may include collecting utility usage data pertaining to a customer premises with a utility meter at the customer premises. The utility usage data may be transmitted automatically from the utility meter to an access point of a public broadband network. The utility usage data may be received at the access point. A digital subscriber line (“DSL”) modem in communication with the access point may modulate the utility usage data at the access point. The utility usage data may be transmitted securely through the public switched telephone network to an Internet point of presence. The utility usage data may be received at the Internet point of presence. The utility usage data may be transmitted from the Internet point of presence to a utility provider via the Internet.

Automatic meter reading system and devices providing for dual mode mesh network and non-mesh network endpoint communication. The system includes a plurality of endpoint devices communicatively coupled to at least one data collection device. At least one endpoint device is configurable to operate in a first mode or a second mode. At least one endpoint is adapted to independently determine whether to operate in the first mode or the second mode. In the first mode the endpoint operates according to a hub-and-spoke communication mode in which it communicates information intended for a data collection infrastructure device directly to at least one dedicated data collection infrastructure device. In the second mode the endpoint operates according to a mesh communications mode in which it communicates information intended for a data collection infrastructure device via a non-dedicated data collection infrastructure device. At least some of the endpoint devices are capable of switching between a mesh-network mode and a non-mesh network mode.
摘要:
A meter reading system of the present invention enables transmission of data between utility meter endpoints and readers. In a first embodiment, the endpoint provides a short message providing its identification to the reader and immediately enters a listen mode. If the reader hears the short message, it can immediately respond and request additional information from the endpoint. If the reader does not hear the short message or does not request additional information during the endpoints listening period, the endpoint enters a sleep mode until its next transmission time. In another embodiment, the endpoint transmits an SCM via AM communication to the reader. The reader can then request additional information and the endpoint can respond with the information via two-way FM communication. In another embodiment, the endpoint is capable of transmitting interval data to the reader via either AM or FM communication.
摘要:
The invention concerns a method of remote metering of energy consumed and/or inputted by a plurality of energy consuming and/or inputting units (4) of a power grid (5) as well as a device for remote metering. Each unit (4) comprises at least one meter (2) and/or a meter box (1) connected with one or more meters (2) and the meter boxes (1) and/or the meters (2) are connected with at least one backend platform (3) via a communication network. At least two of the group of meter boxes (1), meters (2) and backend platforms (3) communicate with each other by means of a generic bi-directional resource management protocol on top of an IP protocol stack via the communication network and thereby encode and decode data transferred via the resource management protocol according to a predefined extensible specification comprising a functional group for meter information and control.
摘要:
The present invention relates to a remote display module (RDM) for display a resource consumption value synchronized with a resource consumption value indicated by a meter metering resource consumption. The RDM is configured with one or more inputs that are electrically associated with the pulse output for a utility meter. The RDM tracks continuous values and associated customer-values. Customers-values may be reset by a customer allowing the customer to easily track resource consumption.
摘要:
A system and method for granting an association request from a mobile terminal, determining, during a predetermined time interval after granting the association request, if the mobile terminal has received traffic from a network and sent traffic to the network and sending a broadcast update packet to the network if it is determined that the mobile terminal has not both received traffic from and sent traffic to the network within the predetermined time interval.
摘要:
An electronic electric meter for use in a networked automatic meter reading environment. The meter includes a meter microcontroller, a measurement microcontroller, a communication microcontroller and spread spectrum processor, and a plurality of other communication interface modules for communicating commodity utilization and power quality data to a utility. The meter measures electricity usage and monitors power quality parameters for transmission to the utility over a spread spectrum local area network (LAN) to a remotely located gateway node. The gateway node transmits this data to the utility over a commercially available fixed wide area network (WAN). The meter also provides direct communication to the utility over a commercially available network interface that plugs into the meter's backplane or bus system, bypassing the local area network communication link and gateway node.
