US 2014/0114440 A1 · SUPERVISOR USER MANAGEMENT SYSTEM

Abstract

An approach for control of users relative to access to controllers of a site in a hierarchy of controllers and building equipment. When a user of a customer has established a read write connection to a site controller, the customer does not necessarily want any subsequent user to establish a read write connection to the site controller or another controller within the same site and also make changes, for example, to settings of building equipment. Thus, a subsequent user may be allowed a read only connection and just be able to view building equipment information. When the first user has disconnected either intentionally or by inactivity, the site controller may be cleared allowing a subsequent user to obtain a read write connection. If the first user is inactive but fails to disconnect from the controller, an auto log-off provision may disconnect the user after a specified period of inactivity.

Claims22

Dependent claims

A control and resolution system for building equipment, comprising:

a supervisor;
one or more of site controllers managed and/or communicated with by the supervisor;
one or more field controllers managed and/or communicated with by a site controller;
and
building equipment controlled by a field controller;
and
wherein:
if a user is to review information of building equipment, the user navigates the supervisor to establish a connection with a site controller cognizant of the building equipment;
if the user is to make changes relative to the information of the building equipment, the user obtains write permission for the connection with the site controller;
a user is a primary user if the user has write permission for the connection to the site controller;
and
virtually any user having a connection to the site controller without write permission is a secondary user.

9 more elements

A supervisor user management system comprising:

a supervisor;
one or more site controllers of a site subject to management by and/or communication with the supervisor;
one or more field controllers subject to management by and/or communication with a site controller of the one or more site controllers;
and
building equipment subject to observation and/or control by a field controller of the one or more field controllers;
and
wherein:
a user navigates the supervisor to connect to a site controller of the one or more site controllers to observe and/or control of building equipment;
and
a first user of one or more users connected to a site controller of the one or more site controllers has write permission relative to the site controller;
if a second user is connected to the site controller of the one or more site controllers, the second user has read only permission relative to the site controller;
and
at least one controller comprises a processor.

10 more elements

A method for managing user access to controllers for building control, comprising:

making a connection for a user to a site controller of one or more controllers of a site;
classifying the user as a primary or secondary user according to a read only or write connection to the site controller, respectively;
and
limiting to one a number of primary users connected to the one or more controllers of the site;
and
wherein the primary user can view site controller information about building control and make changes to the information.
