Abstract

A device for transferring adverse event information from a plurality of remote hydrants to a municipal monitoring server comprises detecting an adverse event in a hydrant that relates to an adverse hydrant condition; transferring data representative of the adverse condition to a host server by routing the data along a predefined hopping path; and transferring the data from the host monitor to the municipal monitoring server. A system for detecting adverse events at a hydrant and event information to a municipal monitoring sever is also disclosed.

Claims

1. A device for detecting adverse events in a fire hydrant, the device comprising:

a housing configured for mating attachment to an exterior of the fire hydrant, the fire hydrant having a standpipe portion with a standpipe aperture therein, the housing having a surface in register with the standpipe portion of the fire hydrant, the surface having a housing aperture therein, the housing aperture aligned with the standpipe aperture;

a controller located within the housing;

a transceiver operably interconnected with the controller, the transceiver adapted to wirelessly transmit data collected by the device to a remote data collection center; and

a plurality of sensors operably interconnected to the controller and positioned with respect to the fire hydrant, the plurality of sensors each configured to detect at least one of a parameter of the fire hydrant or an operational characteristic of the fire hydrant, the plurality of sensors comprising

a water presence sensor and

a tampering sensor.

2. The device of claim 1 wherein the water presence sensor has a probe configured to extend through the aperture in the housing surface and into the interior of the fire hydrant when the housing is mounted to the exterior of the fire hydrant.

3. The device of claim 2 herein the water presence probe has a pair of electrically isolated terminals thereon, which are electrically interconnected when the probe is immersed in a sufficient volume of water.

4. The device of claim 1 wherein the tampering sensor comprises an accelerometer located within the housing, which is configured to generate a signal representative of at least one of movement or vibration of the housing.

5. The device of claim 1 wherein the cap removal sensor comprises a probe adapted to be located between a cap of the fire hydrant and the base therefor, wherein the cap removal sensor is configured to generate a signal representative of the removal of the cap from the base.

6. The device of claim 1 wherein the fire hydrant is dry barrel fire hydrant.

7. The device of claim 1 wherein the transceiver is configured to wirelessly transmit data using a cellular protocol.

8. The device of claim 1 wherein the device comprises a battery sensor.

9. The device of claim 8 wherein the battery sensor detects a battery level and is configured to generate a signal representative of the battery level.

10. The device of claim 1 wherein the transceiver is configured to wirelessly transmit data using a radio frequency network.

11. The device of claim 1, further including a magnetically activated detector to activate the device from a sleep mode to an active mode to enable at least one of additional programming, initiate a water flow test or sense a condition indicative of undesirable tampering.

12. The device of claim 1, wherein the cap sensor comprises a magnetic switch.

13. The device of claim 1 wherein the transceiver has an antenna.

14. The device of claim 13 wherein the antenna is mounted to an exterior surface of the housing and is operably interconnected to the transceiver.

15. The device of claim 1 wherein the plurality of sensors further comprises a cap removal sensor.
