Abstract

A controller in a building management system (BMS) includes an integrated wireless network processor chip. The integrated wireless network processor chip includes a wireless radio, a processor, and memory. The wireless radio is configured to exchange data communications with one or more BMS devices controlled by the controller. Both the processor and memory are in communication with the wireless radio and located on the same chip as the wireless radio. The memory includes communication stacks configured to facilitate communications using a building automation and control network communications protocol and a Wi-Fi communications protocol. The integrated wireless network processor chip receives data from the BMS devices via the wireless radio, formats the data using the processor, stores the data in the memory, and sends the data via the wireless radio without requiring any additional processing or communications components outside the integrated wireless network processor chip.

First claim

What is claimed is:

1. A temperature controller in a building management system (BMS), the temperature controller comprising:
an integrated wireless network processor chip comprising:
a wireless radio configured to communicate with one or more BMS devices;
a processor in communication with the wireless radio and located on a same chip as the wireless radio; and
memory in communication with the wireless radio and located on the same chip as the wireless radio, the memory comprising communication stacks configured to facilitate communication using a building automation and control network communications protocol and a Wi-Fi communications protocol, wherein the integrated wireless network processor chip provides the communication with the one or more BMS devices with a user device configured to access and control one or more of the BMS devices using an application installed on the user device configured to provide a user interface for reading and writing to the one or more BMS devices via the temperature controller;

wherein the integrated wireless network processor chip is configured to receive data from the one or more BMS devices via the wireless radio, format the data from the one or more BMS devices using the processor, and send the data from the one or more BMS devices via the wireless radio to the user device using the Wi-Fi communications protocol; and
wherein the integrated wireless network processor chip is configured to receive data from the user device via the wireless radio, format the data from the user device using the processor, and send the data from the user device via the wireless radio to the one or more BMS devices using the building automation and control network communications protocol.

2. The temperature controller of claim 1 , wherein the wireless radio is an 802.11 b/g/n Wi-Fi radio.

3. The temperature controller of claim 1 , wherein the communication stacks are configured to facilitate communications using a JavaScript Object Notation communications protocol.

4. The temperature controller of claim 1 , wherein the memory comprises a web server configured to generate a web page and serve the web page to the user device via the wireless radio.

5. The temperature controller of claim 4 , wherein the web page comprises at least one of the data from the one or more BMS devices, configuration information for the temperature controller, and commissioning information for the temperature controller.

6. The temperature controller of claim 1 , wherein the memory comprises control logic configured to use the data from the one or more BMS devices to generate a control output that is communicated to the BMS devices via the wireless radio.

7. The temperature controller of claim 1 , wherein the memory comprises a cryptography engine configured to encrypt or decrypt data communicated via the wireless radio.

8. The temperature controller of claim 1 , wherein the integrated wireless network processor chip is configured to receive data from another integrated wireless network processor chip in another temperature controller and relay the data from another integrated wireless network processor chip to a router out of range of the other temperature controller.

9. The temperature controller of claim 1 , wherein the processor is configured to receive internet protocol address using the Wi-Fi communications protocol from the user device.

10. The temperature controller of claim 1 , further comprising a web server configured to generate a web page and serve the web page to the user device via the wireless radio.

11. The temperature controller of claim 1 , wherein the one or more BMS devices comprise a roof top unit or air handling unit.

12. The temperature controller of claim 1 , wherein the one or more BMS devices comprise a roof top unit or air handling and the temperature controller further comprises a web server configured to generate a web page and serve the web page to the user device via the wireless radio, and the wherein the web page comprises data from the roof top unit or air handling unit.

13. The temperature controller of claim 1 , wherein the one or more BMS devices comprise a roof top unit or air handling and the temperature controller further comprises a web server configured to generate a web page and serve the web page to the user device via the wireless radio, and the wherein the web page comprises data comprising configuration information for the temperature controller and commissioning information for the temperature controller.

14. The temperature controller of claim 1 , further comprising a wired temperature input.

15. The temperature controller of claim 1 , wherein the temperature controller is configured to display a humidity parameter.

16. The temperature controller of claim 1 , wherein the processor is configured to broadcast a unique device identification for the temperature controller.

17. The temperature controller of claim 1 , wherein the temperature controller is configured to provide a fan parameter.

18. The temperature controller of claim 1 , wherein the user device is configured to graphically display the one or more BMS devices.

19. The temperature controller of claim 18 , wherein the user device provides an engineering screen.

20. The temperature controller of claim 1 , wherein the user device provides an engineering screen.

21. The temperature controller of claim 1 , wherein the temperature controller is configured to provide a fan speed parameter.
