Abstract

A powerful direct digital control (DDC) and integration control platform that is scalable and easy to use and meet building owners and contractors' desires for a highly secure and robust technical solution. One may combine heating, ventilation and air conditioning (HVAC) DDC control with the embedded workstation platform, and DDC controllers with embedded workstation platform software design. An embedded workstation platform event-driven approach (such as a Windows operating system (OS) or Unix OS environment) is not necessarily easily suited to real-time common in HVAC DDC control. The present system may solve an issue of combining high-power event needs for HVAC DDC Controls.

Claims (66)

1. A method for constructing a secure control system, comprising:

connecting an off-premise internet cloud and tool subsystem across an internet boundary with an on-premise networking infrastructure and control subsystem via one or more secure connections;

connecting the on-premise networking infrastructure and control subsystem with an internet protocol controller subsystem via one or more secure connections, wherein the internet protocol controller subsystem includes:

a first board controlled by a first operating system, the first board including:

a multi port switch having a speed of one or more gigabits per second (Gbps);

a web server;

a first encrypted file system;

a first serial communication manager;

a second board controlled by a second operating system, wherein the second operating system includes a Real Time Operating System (RTOS), the second board including:

a second encrypted file system;

a second serial communication manager, wherein the second serial communication manager is in communication with the first serial communication manager of the first board via a communication channel having a speed of one or more gigabits per second (Gbps);

one or more I/O ports; and

one or more input/output (IO) drivers operatively connected to the second encrypted file system for communicating with one or more external devices via the one or more I/O ports.

2. The method of claim 1 , wherein:

the communication channel between the first serial communication manager module and the second serial communication manager is encrypted; and

the web server is operatively connected to:

a remote communication virtual private network (VPN) connector of the first board; and

the first serial communication manager module of the first board.

3. The method of claim 2 , wherein the remote communication VPN connector is operatively connected to;

the multi port switch; and

a firmware (FW) update service.

4. The method of claim 1 , wherein the switch is a four port switch.

5. The method of claim 1 , wherein the multi port switch is operatively connected via one or more secure connections to a Java™ application control engine (JACE) module of the on-premise networking infrastructure and control subsystem.

6. The method of claim 5 , wherein:

the first board of the internet protocol controller subsystem is operatively connected to a firewall or security or VPN or open module of the on-premise networking infrastructure and control subsystem; and

the firewall or security or VPN or open module of the on-premise networking infrastructure and control subsystem is operatively connected via one or more secure connections to the off-premise internet cloud and tool subsystem across the internet boundary.

7. A control system comprising:

an off-premise internet cloud and tool subsystem, wherein the off-premise internet cloud and the tool subsystem comprises:

a Niagara™ license server connected to a Niagara workbench;

a web browser interface connected to a firewall or security or virtual private network (VPN) or open module;

a remote HVAC user mechanism for operating the web browser interface or the Niagara workbench;

an on-premise networking infrastructure and control subsystem that is operatively coupled to the off-premise internet cloud and tool subsystem via a first secure connection across an internet boundary;

an internet protocol controller subsystem operatively coupled to the on-premise networking infrastructure and control subsystem, wherein the internet protocol controller subsystem includes:

a first card controlled by a first operating system, the first card including:

a multi port switch having a speed of one or more gigabits per second (Gbps);

a web server;

a first encrypted file system;

a first serial communication manager;

a second card controlled by a second operating system, wherein the second operating system includes a Real Time Operating System (RTOS), the second card including:

a second encrypted file system;

a second serial communication manager, wherein the second serial communication manager is in communication with the first serial communication manager of the first card via a communication channel:

one or more I/O ports; and

one or more input/output (IO) drivers operatively connected to the second encrypted file system for communicating with one or more external devices via the one or more I/O ports.

8. The system of claim 7 , wherein the one or more external devices includes a heating, ventilation, and air conditioning (HVAC) device.

9. The system of claim 7 , wherein the one or more external devices includes a local IO device communication subsystem.

10. The system of claim 7 , wherein the one or more external devices includes one or more of an expansion IO device and a physical IO device.

11. The system of claim 7 , wherein the on-premise networking infrastructure and control subsystem comprises:

a firewall or security or VPN or open module having a secure connection to a Niagara workbench; and

a wireless encrypted router connected to the firewall or security or VPN or open module and connected to a wireless encrypted dongle, and a BACnet internet protocol (IP) controller connected to the firewall or security or VPN or open module.

12. The system of claim 7 , wherein the internal protocol controller subsystem comprises:

a remote communication VPN connector to support the first secure connection.

13. An internet protocol controller subsystem comprising:

a first board controlled by a first operating system, the first board including:

a multi port switch having a speed of one or more gigabits per second (Gbps);

a web server;

a first encrypted file system;

a first serial communication manager;

a second board controlled by a second operating system, wherein the second operating system includes a Real Time Operating System (RTOS), the second board including:

a second encrypted file system;

a second serial communication manager, wherein the second serial communication manager is in communication with the first serial communication manager of the first board via a communication channel having a speed of one or more gigabits per second (Gbps);

one or more I/O ports; and

one or more input/output (IO) drivers operatively connected to the second encrypted file system for communicating with one or more external devices via the one or more I/O ports.

14. The internet protocol controller subsystem of claim 13 , wherein the web server is operatively connected to a remote communication virtual private network (VPN) connector and to the first serial communication manager, and wherein the first serial communication manager is operatively connected to the first encrypted file system and has a secure connection to the second serial communication manager.

15. The internet protocol controller subsystem of claim 14 , wherein the remote communication VPN connector is operatively connected to the multi-port switch.

16. The internet protocol controller subsystem of claim 13 , wherein the multi-port switch is a four port switch.

17. The internet protocol controller subsystem of claim 13 , wherein the one or more external devices comprise a remote heating, ventilation and air conditioning (HVAC) device.
