摘要:
Disclosed is a power metering system, a method and a system for monitoring power consumed by loads by using the power metering system. The system for monitoring power consumed by loads includes an external power supply source (110), a renewable energy source, a distribution board (120), one or more power metering systems, and a monitoring server (10).
摘要:
The load power monitoring system according to an embodiment of the present disclosure includes a distribution board to distribute a electric power applied from a external electric power supply source (110) or a first renewable energy source (140) to an electric device, at least one power metering device to sense electric energy of at least one of the electric power supply source (110) and the first renewable energy source (140), a second power metering device to sense electric energy distributed to the electric device (130), a third power metering device to sense electric energy generated from a second renewable energy source (150), and a monitoring server (10) to collect electric energy data sensed at each of the power metering devices and monitor the load power based on the collected electric energy data
摘要:
A metering device (11) is configured to collect meter reading data and transmit the meter reading data to a remote system (13) through a wireless communication network (12). Further, the metering device (11) is configured to adjust a start timing of predetermined communication based on predetermined information that is received before starting the predetermined communication after restoration of power supply to the metering device (11). As a result, for example, it is possible to adjust a communication start timing of the metering device according to the situation of the occurrence of a power supply interruption or the situation at the time of a power supply restoration.
摘要:
Systems and methods for distributing a firmware upgrade within a mesh network are provided. In one implementation, a firmware upgrade distributing system comprises a utility provider, which is configured to provide utility services to a plurality of customers, a plurality of meters, and a plurality of nodes. Each meter is configured to measure utility usage data of a respective customer. The nodes are configured to transmit the utility usage data from the plurality of meters to the utility provider. When at least one of the meters is scheduled to receive a firmware upgrade, the utility provider is configured to forward the firmware upgrade to at least one of the plurality of nodes. The at least one node is configured to receive and store the firmware upgrade and, after storing the firmware upgrade, is further configured to forward the firmware upgrade to at least one of the plurality of meters.
摘要:
A redundant sensor (10) includes at least two sensing elements (6). The redundant sensor includes methods and apparatus for time-stamping and combining data from the sensing elements (6). A method of use and additional embodiments are disclosed.
