Systems and methods for remote utility metering and meter monitoring
View Patent ↗A remote water meter monitoring system is provided. A mesh network-type transceiver unit is coupled to a water meter housing having a water counting mechanism inside to transmit water consumption information as well as other sensor information, such as backflow detection, water pressure, and water metrics (e.g., residual chlorine and temperature) to a central server system via a bridge device and a corresponding mesh network. Mechanical energy from the water flowing through the water meter housing is converted to electrical energy via an energy conversion unit. An electrically powered shut off valve is remote addressable via the transceiver unit.
1. A remote water meter monitoring system comprising:
a water meter body coupling a water supply source to a water customer;
a flow meter contained within the water body that is configured to measure a flow rate of water through the water meter;
a power supply system disposed within the water meter body, the power supply system including at least one battery and a power generator, wherein the power generator is powered by a flow of water through the water meter body;
a controller disposed within the water meter body and communicatively coupled to the water meter body and power supply system; and
at least one antenna connected to the controller; and
wherein the controller is coupled to the flow meter and configured to calculate water consumption based on signals received from the flow meter; and
wherein the controller is configured to perform steps comprising:
awaking from a sleep state;
checking battery charge levels and adjusting a charging cycle in response to available power;
preparing a data packet for transmitting water consumption data to a collector;
listening for a communication from a collector;
transmitting the prepared data packet; and
returning to a sleep state.
2. The system of claim 1 , the communication in the form of a routing beacon.
3. The system of claim 1 , the controller is configured to perform further steps comprising resetting a timer subsequent to sending the data packet.
4. The system of claim 1 , the flow meter contained within the water meter body configured to measure a bidirectional flow rate of water through the water meter.
5. The system of claim 1 , wherein the controller is a microcontroller within a wireless mote.
6. The system according to claim 1 , wherein the controller and antenna are configured to transmit and receive information from and send information to the system.
7. The system according to claim 1 , wherein the controller and antenna are configured to send water usage information wirelessly to a bridge device.
8. The system according to claim 7 , wherein sending water usage information comprises sending information either directly or through one or more other water meter monitoring systems.
9. The system according to claim 7 , wherein the system is configured to receive at least one command from the wireless bridge device.
10. The system according to claim 9 , wherein the at least one command is a command selected from the group consisting of a meter reading transmission request, a status request, and a water shutoff request.
11. The system according to claim 1 , wherein the water meter body further comprises a shut off valve.
12. The system according to claim 11 , wherein the shut off valve may be remotely activated by a wireless signal received by the system.
13. The system according to claim 11 , wherein the flow sensor is adapted to detect reverse water flow and to cause the shut off valve to trigger when reverse water flow exceeds a predetermined volume.
14. The system according to claim 1 , wherein the water meter further comprises at least one water quality sensor.
15. The system according to claim 1 , wherein the controller is configured to send periodic water usage information wirelessly to the water customer.
16. The system according to claim 1 , wherein the system is remotely addressable via a communications network with a network content browser.
