Filed:

Dec 5, 2011

Appl. No.:

13/310825

Inventors:

Dong Wei - Edison NJ, US
Livio Dalloro - Princeton NJ, US
Yan Lu - West Windsor NJ, US

Assignee:

Siemens Corporation - Iselin NJ

International Classification:

H04L 29/06
G08B 21/00

US Classification:

713152

Abstract:

Embodiments provide an application layer security proxy that protects substation automation systems. The application layer security proxy inspects a received, inbound data packet at the application layer, and either drops the data packet, forwards the data packet, or processes the data packet rather than dropping it in order to maintain the communications network connection, the later two according to a predefined role-based access control policy. The application layer security proxy calculates a round trip time for each reply to a received, inbound data packet and observes the bandwidth usage from the amount of bytes transmitted. Round trip time and bandwidth usage are used to detect abnormal communication traffic.

International Classification:

G05B 13/02

US Classification:

700286

Abstract:

A system for collaborative energy management and control in a building, including an energy management controller, one or more occupant HMIs that supports two-way communication between building occupants and a facility manager, and between building occupants and the energy management controller, and a facility manager HMI that supports two-way communication between the facility manager and the building occupants, and between the facility manager and the energy management controller, in which the occupant HMI allows building occupants to provide temperature preferences to the facility manager and the energy management controller, and the facility manager HMI allows the facility manager to configure an energy policy for the building as a set of rules and to view occupants' aggregated temperature preferences, and the energy management controller determines an optimum temperature range that resolves conflicting occupant temperature preferences and occupant temperature preferences that conflict with the facility manager's energy policy for the building.

International Classification:

G05B 19/418

Abstract:

A method for energy demand management in a production flow line having a plurality of stations. The method includes calculating a slack time for the production flow line or a selected station and determining an option of operation mode flexibility. In addition the method includes performing a feasibility analysis of the option and providing a solution based on an elasticity measure. The method is supported by a mean value analysis technique and discrete event simulation. The method provides an automated energy auditing and analysis tool in a production system.
