Systems and methods for voice control of BMS devices

1. A portable gateway device for use with a Building Management System (BMS), the portable gateway device comprising:

a Wi-Fi module configured to enable communication with a user device via Wi-Fi, the portable gateway device configured to receive a voice command spoken by a user of the user device, wherein the user device translates the voice command into JSON data and provides the JSON data to the Wi-Fi module;

a serial communications interface configured to enable communication with a bus, the bus connected to a BMS device; and

a data conversion module configured to translate the JSON data received from the user device into a control action associated with the BMS device;

wherein the portable gateway device is configured to provide the control action to the BMS device via the serial communications interface, the control action affecting a state or condition of the BMS device.

2. The portable gateway device of claim 1 , wherein the BMS device is a sensor, a controller, an actuator, a chiller, a boiler, a pump, a fan, an air handling unit (AHU), a variable air volume unit (VAV), a damper, or an alarm.

3. The portable gateway device of claim 1 , wherein the bus is a Building Automation and Control network (BACnet) Master-Slave Token-Passing (MS/TP) bus.

4. The portable gateway device of claim 1 , wherein the control action is a temperature setpoint, a speed setpoint, a pressure setpoint, a mode, an on/off command, or a time period.

5. The portable gateway device of claim 1 , further configured to receive the voice command from the user device in JSON format.

6. The portable gateway device of claim 1 , further comprising an Ethernet port configured to enable connection to a remote bus, the remote bus connected to one or more additional BMS devices.

7. The portable gateway device of claim 1 , wherein:

the BMS device is a data object; and

the control action comprises adjusting one or more properties of the data object.

8. A system comprising:

a BMS device connected to a serial communications bus;

an application installed on a user device, the application configured to:

receive a voice command from a user of the user device via a microphone of the user device; and

translate the voice command into JSON data; and

a portable gateway device configured to:

receive the JSON data from the user device via a Wi-Fi connection;

translate the JSON data into a control action associated with the BMS device; and

provide the control action to the BMS device via the serial communications bus, the control action affecting a state or condition of the BMS device.

9. The system of claim 8 , wherein the BMS device is a sensor, a controller, an actuator, a chiller, a boiler, a pump, a fan, an air handling unit (AHU), a variable air volume unit (VAV), a damper, or an alarm.

10. The system of claim 8 , wherein the serial communications bus is a Building Automation and Control network (BACnet) Master-Slave Token-Passing (MS/TP) bus.

11. The system of claim 8 , wherein the control action is a temperature setpoint, a speed setpoint, a pressure setpoint, a mode, an on/off command, or a time period.

12. The system of claim 8 , wherein the application is further configured to provide a response to the user based on the voice command.

13. The system of claim 8 , wherein the application is further configured to initiate a biometric login process when the user access the application.

14. The system of claim 8 , wherein the application is further configured to convert the voice command into a text string.

15. The system of claim 8 , wherein the JSON data includes an object or an array.

16. A method for controlling a Building Management System (BMS) device, the method comprising:

receiving, by a portable gateway device, JSON data from a user device via a Wi-Fi connection, the user device configured to translate a voice command from the user device into the JSON data;

translating, by the portable gateway device, the voice command as JSON data into a control action associated with the BMS device;

establishing, by the portable gateway device, a connection to the BMS device via a serial communications bus; and

providing, by the portable gateway device, the control action to the BMS device via the serial communications bus, the control action affecting a state or condition of the BMS device.

17. The method of claim 16 , wherein the BMS device is a sensor, a controller, an actuator, a chiller, a boiler, a pump, a fan, an air handling unit (AHU), a variable air volume unit (VAV), a damper, or an alarm.

18. The method of claim 16 , wherein the control action is a temperature setpoint, a speed setpoint, a pressure setpoint, a mode, an on/off command, or a time period.

19. The method of claim 16 , wherein receiving the voice command from the user device comprises receiving a JSON data object or a JSON data array.

20. The method of claim 16 , wherein establishing a connection to the BMS device via the serial communications bus comprises:

connecting to the serial communications bus directly via a serial interface of the portable gateway device; or

connecting to the serial communications bus remotely via an Ethernet interface of the portable gateway device.

21. The method of claim 16 , further comprising providing information about the BMS device to the user by transmitting the information about the BMS device from the portable gateway device to the user device.
