Abstract

A building control system is provided that receives information from devices of different subsystems. A trigger causes a zone controller to store the information in a database. The stored data is used to generate customized reports based on sequences or sets of related events. The information from multiple subsystems is consolidated, analyzed, and patterns of behavior are determined. The trigger also causes execution of control actions throughout the building spanning the multiple subsystems, devices, and areas based on the information. An access control subsystem and a non-access control subsystem of the building control system are linked using a common network such that a change in the state of an access control device can affect the state of a non-access control device and a change in the state of a non-access control device can affect the state of an access control device.

Claims

1. A building control system comprising:

a plurality of subsystems including an access control subsystem containing a plurality of access control devices and a non-access control subsystem containing a plurality of non-access control devices, at least some of the access control devices and non-access control devices distributed on a common communication network;

a plurality of zone controllers each having a central processing unit, a database, an embedded operating system, and a module assembly with a plurality of input/output (i/o) modules, each zone controller configurable via the common communication network, each zone controller operational as a local area controller; and

a network management system configured to manage the zone controllers and the subsystems via the common communication network.

2. The building control system of claim 1, wherein each zone controller is configured to receive information from devices of multiple subsystems using different protocols through the i/o modules.

3. The building control system of claim 1, wherein the non-access control subsystem comprises a security subsystem, a lighting subsystem, a HVAC (heating, ventilating, and air conditioning) subsystem, a fire protection subsystem, and a utility metering subsystem, the non-access control devices comprising:

HVAC equipment, fire protection equipment, intrusion control equipment, irrigation equipment, video surveillance equipment, audio intercommunication equipment, lighting equipment, utility metering and delivery equipment, or public address equipment.

4. The building control system of claim 1, wherein the access control subsystem comprises access control devices associated with different doors in different physical areas of a building, the building control system configured such that a state of an access control device associated with a first door is capable of affecting a state of an access control device associated with a second door, the state of the access control device associated with the first door is capable of affecting a state of a non-access control device associated with a physical area adjacent to the first door, and a state of a non-access control device associated with multiple physical areas is capable of affecting the state of the access control device associated with at least one of the first or second doors.

5. The building control system of claim 1, wherein each zone controller is configured to read in software objects sent via different protocols from third party devices and to process signals from sensors and actuators coupled with the i/o modules to affect measurement and control of a building environmental parameter including at least one of:

temperature, humidity, light level, air quality, energy usage rate, smoke level, or physical access

6. The building control system of claim 1, wherein the communication network comprises an Ethernet network and at least one of the zone controllers is configured to receive power via a Power Over Ethernet (PoE) connection.

7. The building control system of claim 1, wherein the network management system is configured to interact with a user using web-based tools.

8. The building control system of claim 1, wherein the database comprises stored data, the zone controller configured to use the stored data to generate customized reports based on sequences or sets of related events.

9. The building control system of claim 1, wherein in response to a triggering event the zone controller is configured to at least one of:

record a predetermined sequence of data or execute a control action sequence.

10.
