Abstract

A system comprises a plurality of sensors disposed at predetermined locations in a fluid distribution network and a server receiving sensor data from the sensors indicative of at least one predetermined characteristic of flow through the network, the server comparing the sensor data to stored data to determine an existence of a problem condition in the network and, when a problem condition is determined to exist, executing a predetermined response procedure.

Claims

1. A system, comprising:

a plurality of sensors disposed at predetermined locations in a fluid distribution network, wherein the sensors include at least one of Motes and Smartdust; and

a server receiving sensor data from the sensors indicative of at least one predetermined characteristic of flow through the network, the server comparing the sensor data to stored data to determine an existence of a problem condition in the network and, when the problem condition is determined to exist, executing a predetermined response procedure, the server including a display showing a map image of the fluid distribution network, wherein the server utilizes a layering function to project on the map image at least one of (i) a topography of land underlying the fluid distribution network, (ii) an infrastructure of the fluid distribution network, (iii) locations of the plurality of sensors and (iv) the sensor data generated by each of the plurality of sensors.

2. The system according to claim 1, wherein the network is one of a drinking water network, a sewage network, an oil network, a gas network and an irrigation network.

3. The system according to claim 1, wherein each sensor includes a sensing arrangement generating the sensor data and a communication arrangement communicating the sensor data over a communications network to one of at least one further sensor and the server.

4. The system according to claim 3, wherein the communications network is one of a wireless mesh network, a WLAN and a WWAN.

5. The system according to claim 1, wherein sensor data includes at least one of temperature, humidity, barometric pressure, ambient light, pressure, flow rate, conductivity, dissolved oxygen, hydrogen sulfide gas and contaminant level.

6. The system according to claim 1, wherein the sensors are grouped into subnets managed by a subnet head arrangement which communicates the sensor data from the sensors to the server.

7. The system according to claim 6, wherein the protocol is one of 802.11, GPRS and ZigBee.

8. The system according to claim 1, wherein the sensors communicate with the server according to a predetermined wireless communication protocol.

9. The system according to claim 1, wherein the server utilizes at least one of (i) a fluid distribution network modeling module generating the stored data, (ii) a controller module controlling operation of components of the fluid distribution network, (iii) a learning module using the sensor data to generate the response procedure and (iv) a customer meter module obtaining a reading from a meter at a customer location.

10. The system according to claim 9, wherein the components include at least one of a valve, a pump and a tank.

11. The system according to claim 1, wherein the response procedure includes at least one of (i) an alert message to a field personnel, (ii) a visual indicator on a display coupled to the server and (iii) generating a list of responsive actions.

12. A method, comprising:

receiving sensor data from a plurality of sensors disposed at predetermined locations in a fluid distribution network, the sensor data indicative of at least one predetermined characteristic of flow through the network, wherein the sensors include one of Motes and Smartdust;

comparing the sensor data to stored data to determine an existence of a problem condition in the network;

executing a predetermined response procedure when the problem condition is determined to exist;

displaying a map image of the fluid distribution network; and

utilizing a layering function to project on the map image at least one of (i) a topography of land underlying the fluid distribution network, (ii) an infrastructure of the fluid distribution network, (iii) locations of at least a portion of the plurality of sensors and (iv) the sensor data generated by each of the plurality of sensors.

13. The method according to claim 12, wherein the network is one of a drinking water network, a sewage network, an oil network, a gas network and an irrigation network.

14. The method according to claim 12, wherein sensor data includes at least one of temperature, humidity, barometric pressure, ambient light, pressure, flow rate, conductivity, dissolved oxygen, hydrogen sulfide gas and contaminant level.

15. The method according to claim 12, further comprising:

generating the stored data using a fluid distribution network modeling module.

16. The method according to claim 12, further comprising:

controlling operation of components of the fluid distribution network as a function of the response procedure.

17. The method according to claim 12, wherein the components include at least one of valves, pumps and tanks.

18. The method according to claim 12, wherein the response procedure includes at least one of (i) an alert message to a field personnel, (ii) a visual indicator on a display and (iii) generating a list of responsive action.
