Systems and methods utilizing a wireless mesh network
In some examples, a wireless controller is utilized within a wireless mesh network. The wireless controller includes a control module configured to manage at least one energy device via a pneumatic pressure line based on one or more parts of an energy profile; and a network interface module configured to transmit energy data to a management server and receive the one or more parts of the energy profile from the management server.
1. A wireless controller, comprising:
a control module configured to manage at least one HVAC device controlled by a pneumatic pressure line via active room temperature feedback, and active pressure feedback from a piezoresistive sensor measuring pressure in the pneumatic pressure line, and command signals to a piezoelectric valve controlling the pneumatic pressure line based on one or more parts of an energy profile, the piezoelectric valve comprising a piezo bleed valve configured to decrease pressure in the pneumatic pressure line and a piezo feed valve configured to increase pressure in the pneumatic pressure line; and
a network interface module configured to wirelessly transmit energy data to a management server and receive the one or more parts of the energy profile from the management server.
2. The wireless controller of claim 1 , wherein the piezoelectric valve is configured to modify the pressure in the pneumatic pressure line proportionally to offset a difference in a measured temperature from a set-point according to the energy profile.
3. The wireless controller of claim 1 , wherein the at least one energy device comprises a heating, ventilation, and air conditioning (HVAC) unit.
4. The wireless controller of claim 1 , further comprising a pressure controller configured to modify a pressure in the pneumatic pressure line based on pressure feedback information, a thermal load in one or more controlled zones, one or more parts of the energy profile, or any combinations thereof.
5. The wireless controller of claim 1 , further comprising a pressure controller configured to modify a pressure in the pneumatic pressure line proportionally to offset the difference in a measured temperature from a set-point temperature.
6. The wireless controller of claim 5 , wherein the modification of the pressure in the pneumatic pressure line is an increase or decrease in the pressure in the pneumatic pressure line.
7. The wireless controller of claim 5 , wherein the modification of the pressure in the pneumatic pressure line is an increase or decrease in the pressure directly proportionally to a positive or negative difference in the measured temperature from the set-point temperature.
8. The wireless controller of claim 1 further comprising:
a pressure controller configured to determine a temperature difference between a measured temperature and a set-point temperature; and
the controller further configured to adjust a branch line pressure based on a gain value, where the gain value is a ratio between a pressure change in the branch line and the temperature difference.
9. The wireless controller of claim 1 further comprising a pressure controller configured to modify a set point pressure of a pneumatic pressure line, wherein the set point pressure is a pressure that a branch line pressure is regulated at when a measured temperature agrees with a set point temperature.
10. The wireless controller of claim 1 , further comprising the network interface module further configured to route and/or forward communication via a wireless mesh network.
11. The wireless controller of claim 1 , further comprising the network interface module further configured to receive a configuration command, the configuration command comprises a modification to acting direction, a throttling range, set point pressure, gain, and dead band for one or more of the at least one energy device.
12. The wireless controller of claim 1 , further comprising the control module further configured to replace an existing pneumatic thermostat.
13. The wireless controller of claim 1 , wherein the piezoelectric valve requires no calibration over the operational life of the pressure controller.
14. The wireless controller of claim 1 , wherein the network interface module is further configured to route and/or forward communication via a wireless mesh network.
15. The wireless controller of claim 14 , wherein the control module is configured to forward high and low duty cycle commands through the network interface module via the wireless mesh network.
16. The wireless controller of claim 1 , wherein the network interface module is further configured to receive a configuration command, the configuration command comprises a modification to acting direction, a throttling range, set point pressure, gain, and dead band for one or more of the at least HVAC device.
17. The wireless controller of claim 1 , wherein the control module is configured to de-activate the wireless controller to enter a low power mode.
