Abstract

A fire-fighting vehicle includes a boom assembly movably coupled to a chassis, a penetrating nozzle coupled to the boom assembly, an actuator that moves the penetrating nozzle relative to the chassis, and a controller operatively coupled to a sensor. The penetrating nozzle includes a piercing tip and an outlet configured to be selectively fluidly coupled to a supply of fire suppressant. The piercing tip is repositionable between a first position spaced from a surface of an object and a second position within an interior cavity of the object. The outlet supplies fire suppressant into the interior cavity when the piercing tip is in the second position. The sensor provides data relating to at least one of a position and an orientation of the piercing tip relative to the surface. The controller determines an angular orientation of the piercing tip relative to the surface based on the data.

First claim

What is claimed is:

1. A fire-fighting vehicle, comprising:
a chassis;
a boom assembly movably coupled to the chassis;
a penetrating nozzle coupled to the boom assembly, the penetrating nozzle including:
a piercing tip extending along a longitudinal axis and configured to be selectively repositioned between a first position that is spaced from a surface of an object having an interior cavity and a second position that is within the interior cavity of the object; and
an outlet configured to be selectively fluidly coupled to a supply of fire suppressant, wherein the outlet is positioned to supply fire suppressant into the interior cavity when the piercing tip is in the second position;

an actuator configured to rotate the penetrating nozzle relative to the chassis;
a range sensor configured to provide range data relating to a distance between the piercing tip and the surface; and
a controller comprising a processing circuit configured to receive the range data, wherein the controller is configured to engage the actuator such that the penetrating nozzle sweeps through an angular range at least one of automatically and in response to a user request, wherein the controller is configured to store the range data corresponding to various angular positions of the penetrating nozzle as the actuator rotates the penetrating nozzle, and wherein the controller is configured to determine an angular orientation of the piercing tip relative to the surface using the stored range data; and
wherein the controller is configured to determine a target range of angular orientations for the penetrating nozzle relative to the surface, wherein the controller is configured to determine the target range of angular orientations based on an evaluation of orientations that have elevated likelihoods of successfully penetrating the surface, wherein the target range of angular orientations includes an angular orientation in which the distance between the piercing tip and the surface is smallest.

2. The fire-fighting vehicle of claim 1 , further comprising an angle sensor, wherein the longitudinal axis of the penetrating nozzle defines a first axis, wherein the boom assembly includes a first section coupled to the chassis, a second section slidably coupled to the first section and coupled to the penetrating nozzle, and a second actuator, wherein the second actuator is configured to extend and retract the second section relative to the first section along a second axis, wherein the angle sensor is operatively coupled to the controller and configured to provide angle data relating to an angle between the first axis and the second axis, and wherein the controller is configured to determine at least one of an absolute and a relative amount of force applied by the piercing tip based on the angle data.

3. The fire-fighting vehicle of claim 1 , further comprising a user interface and an angle sensor, wherein the user interface and the angle sensor are both operatively coupled to the controller, wherein the angle sensor is configured to provide angle data relating to an angular orientation of the longitudinal axis relative to at least a portion of the boom assembly, and wherein the controller is configured to provide, for representation on the user interface, a graphical display showing at least one of a position and an orientation of the piercing tip relative to the surface and relative to the boom assembly.

4. The fire-fighting vehicle of claim 3 , wherein the graphical display further comprises information including at least one of (a) a current distance between the piercing tip and the surface and (b) a current angle between the longitudinal axis of the penetrating nozzle and a horizontal plane.

5. The fire-fighting vehicle of claim 3 , wherein the controller is configured to determine whether the penetrating nozzle has penetrated a threshold distance into the object, and wherein the threshold distance is based on an insertion depth that facilitates fire suppressant introduction, through the outlet, into the interior cavity.

6. A fire-fighting vehicle, comprising:
a chassis;
a boom assembly movably coupled to the chassis;
a penetrating nozzle coupled to the boom assembly, the penetrating nozzle including:
a piercing tip extending along a longitudinal axis and configured to be selectively repositioned between a first position that is spaced from a surface of an object having an interior cavity and a second position that is within the interior cavity of the object; and
an outlet configured to be selectively fluidly coupled to a supply of fire suppressant, wherein the outlet is positioned to supply fire suppressant into the interior cavity when the piercing tip is in the second position;

an actuator configured to rotate the penetrating nozzle relative to the chassis;
a range sensor configured to provide range data relating to a distance between the piercing tip and the surface;
a controller comprising a processing circuit configured to receive the range data;
a user interface operatively coupled to the controller; and
an angle sensor operatively coupled to the controller and configured to provide angle data relating to an angular orientation of the longitudinal axis relative to at least a portion of the boom assembly,
wherein the controller is configured to engage the actuator such that the penetrating nozzle sweeps through an angular range at least one of automatically and in response to a user request, wherein the controller is configured to store the range data corresponding to various angular positions of the penetrating nozzle as the actuator rotates the penetrating nozzle, and wherein the controller is configured to determine an angular orientation of the piercing tip relative to the surface using the stored range data; and
wherein the controller is configured to provide, for representation on the user interface, a graphical display showing at least one of a position and an orientation of the piercing tip relative to the surface and relative to the boom assembly, wherein the controller is configured to determine whether the penetrating nozzle has penetrated a threshold distance into the object, and wherein the threshold distance is based on an insertion depth that facilitates fire suppressant introduction, through the outlet, into the interior cavity.

7. The fire-fighting vehicle of claim 6 , wherein the controller is configured to determine a target range of angular orientations for the penetrating nozzle relative to the surface, wherein the controller is configured to determine the target range of angular orientations based on an evaluation of orientations that have elevated likelihoods of successfully penetrating the surface, wherein the target range of angular orientations includes an angular orientation in which the distance between the piercing tip and the surface is smallest.

8. The fire-fighting vehicle of claim 7 , wherein the longitudinal axis of the penetrating nozzle defines a first axis, wherein the boom assembly includes a first section coupled to the chassis, a second section slidably coupled to the first section and coupled to the penetrating nozzle, and a second actuator, wherein the second actuator is configured to extend and retract the second section relative to the first section along a second axis, wherein the angle data relates to an angle between the first axis and the second axis, and wherein the controller is configured to determine at least one of an absolute and a relative amount of force applied by the piercing tip based on the angle data.

9. The fire-fighting vehicle of claim 6 , wherein the graphical display further comprises information including at least one of (a) a current distance between the piercing tip and the surface and (
