Branch Circuit Monitor

摘要

A branch circuit monitoring system (BCMS) for monitoring branch circuit currents in one or more electrical circuit panels is described. The system is comprised of a data center server, one or more panel processors, each with one or more collection devices, and one or more current sensors per collection device. The BCMS is designed to be installed entirely inside the panel without the need for a dedicated enclosure or power supply to facilitate ease of installation and low-cost. The BCMS also allows for future upgradability through standard software updates so that the system can be updated or patched easily. The BCMS data center server collects, aggregates, stores, and serves historical branch circuit current data from the panel processors to networked users via a web server to provide visualization of data such as tables, charts, and gauges. Finally, the BCMS interfaces to third-party software suites using industry-standard protocols such as Modbus® TCP and BACnet™ for integration with data center infrastructure management or building management system software.

1. A branch circuit monitoring system, comprising:
a first collection device configured to receive direct current (DC) signals indicative of a measured DC current value from a first plurality of current monitors and multiplex the DC signals from the first plurality of current monitors; a second collection device configured to receive DC signals indicative of a measured DC current value from a second plurality of current monitors and multiplex the DC signals from the second plurality of current monitors; a panel processor device in communication with the first and second collection devices configured to receive the DC signals from each of the first and second current monitors, the panel processor device configured to store in a local memory a plurality of data structures comprising the measured DC current data values.
