Power monitoring system with proxy server for processing and transforming messages and context-specific caching

摘要

An electrical power monitoring system includes a proxy server between (1) monitoring devices coupled to an electrical power distribution system for sensing and storing data representing operating characteristics of the power distribution system, and (2) at least one client device coupled to the monitoring devices for requesting data from the monitoring device and processing, storing and presenting data received from the monitoring devices. A communications network is coupled to the monitoring and client devices, and proxy server is coupled to the communications network for processing and transforming messages and context-specific caching. The proxy server receives messages from the client device as a virtual device, processes the messages, and alters the messages before communicating the messages to the monitoring devices to which the messages are directed, or defers communication of at least portions of the messages to the actual monitoring devices to which the requests are directed until a later time.

主权项

1. An electrical power monitoring system for monitoring an electrical power distribution system, comprising:
at least one monitoring device adapted to be coupled to said electrical power distribution system for sensing and storing data representing operating characteristics of said electrical power distribution system, at least one client device coupled to said at least one monitoring device for requesting data from said at least one monitoring device and processing, storing and presenting data received from said at least one monitoring device, a communications network coupled to said monitoring and client devices, and a proxy server coupled to said communications network for receiving client messages from said at least one client device as a virtual device that is a continuously updating, virtual model of the measurement and configuration data state of said at least one monitoring device, the proxy server
processing said client messages,determining, for each of the processed client messages, whether to apply said client message to said virtual device and whether to forward said client message to said at least one monitoring device, anddepending on predetermined proxy rules, either (a) applying said client message to said virtual device and providing a response back to said at least one client device, or (b) forwarding said client message to said at least one monitoring device and providing a response back to said at least one client device.
