Abstract

A fire apparatus includes an engine, a water tank configured to store water, an agent tank configured to store a fire suppressing agent, a fuel tank configured to store a fuel used to power the engine, and a processing circuit. The processing circuit is configured to monitor the fluid level data indicating at least one of a water level within the water tank, a fire suppressing agent level within the agent tank, and a fuel level within the fuel tank; monitor fault data indicating any active faults of the fire apparatus; monitor maintenance data indicating whether maintenance is due; monitor exercise data indicating an elapsed time since the fire apparatus was last exercised; determine a readiness score based on the fluid level data, fault data, maintenance data, and exercise data; and at least one of transmit the readiness score to (i) a display device and (ii) a remote server.

Claims

1. A fire apparatus, comprising:

an engine;

a water tank configured to store water;

an agent tank configured to store a fire suppressing agent;

a fuel tank configured to store a fuel used to power the engine; and

a processing circuit configured to;

monitor fluid level data indicating at least one of a water level within the water tank, a fire suppressing agent level within the agent tank, and a fuel level within the fuel tank;

monitor fault data indicating any active faults with components of the fire apparatus;

monitor maintenance data indicating whether maintenance is due or overdue;

monitor exercise data indicating an elapsed time since the fire apparatus was last exercised;

identify one or more primary factors, one or more primary reducers, and one or more secondary reducers from the fluid level data, the fault data, the maintenance data, and the exercise data, wherein the one or more primary factors include at least one of (i) the water level within the water tank and (ii) the fire suppressing agent level within the agent tank, wherein the one or more primary reducers include at least one of (i) the fuel level within the fuel tank and (ii) active serious faults, and wherein the one or more secondary reducers include at least one of (i) a diesel exhaust fluid level within a diesel exhaust fluid reservoir, (ii) active moderate faults, (iii) the maintenance being due or overdue, and (iv) the elapsed time since the fire apparatus was last exercised;

determine a primary factor value associated with the one or more primary factors, a primary reducer value associated with the one or more primary reducers, and a secondary reducer value associated with the one or more secondary reducers; and

determine a readiness score for the fire apparatus by subtracting the primary reducer value and the secondary reducer value from the primary factor value; and

at least one of transmit the readiness score to (i) a display device configured to display a readiness graphical user interface including the readiness score to an operator of the fire apparatus and (ii) a remote server.

2. The fire apparatus of claim 1, wherein the processing circuit is configured to select the lower of a value associated the water level and a value associated with the fire suppressing agent level as the primary factor value.

3. The fire apparatus of claim 1, wherein the processing circuit is configured to determine the primary reducer value based on (i) an amount of the fuel tank that is empty and (ii) a predetermined value for each of the active serious faults.

4. The fire apparatus of claim 1, further comprising the diesel exhaust fluid reservoir configured to store a diesel exhaust fluid, wherein the fluid level data further indicates the diesel exhaust fluid level within the diesel exhaust fluid reservoir.

5. The fire apparatus of claim 1, wherein the processing circuit is configured to determine the secondary reducer value based on at least one of (i) a proportion of an amount of the diesel exhaust fluid reservoir that is empty, (ii) a predetermined value for each of the active moderate faults, (iii) a predetermined value for the maintenance being due or overdue, and (iv) a value for the elapsed time since the fire apparatus was last exercised as a function of time.

6. The fire apparatus of claim 1, wherein the readiness graphical user interface includes a readiness factor section that lists a plurality of readiness factors having an associated status or value, wherein the processing circuit is configured to display each readiness factor in one of various colors based on the associated status or value of each readiness factor relative to one or more threshold statuses or values.

7. The fire apparatus of claim 1, wherein the display device includes at least one of a vehicle mounted display and a portable user device.

8. The fire apparatus of claim 1, wherein the remote server is configured to receive the readiness score from a plurality of fire apparatuses of a fleet and provide a comprehensive readiness report for the fleet.

9. The fire apparatus of claim 1, wherein the processing circuit is configured to classify each active fault as either a serious fault or a moderate fault.

10. A method for evaluating a readiness of a fire apparatus to respond to an incident, comprising:

monitoring, by a processing circuit received from a sensor, fluid level data indicating at least one of (i) a water level within a water tank of a fire apparatus, (ii) a fire suppressing agent level within an agent tank of the fire apparatus, (iii) a fuel level within a fuel tank of the fire apparatus, and (iv) a diesel exhaust fluid level within a diesel exhaust fluid reservoir of the fire apparatus;

monitoring, by the processing circuit, fault data indicating any active faults with components of the fire apparatus;

monitoring, by the processing circuit, maintenance data indicating whether maintenance is due or overdue;

monitoring, by the processing circuit, exercise data indicating an elapsed time since the fire apparatus was last exercised;

identifying, by the processing circuit, one or more primary factors, one or more primary reducers, and one or more secondary reducers from the fluid level data, the fault data, the maintenance data, and the exercise data, wherein the one or more primary factors include at least one of (i) the water level within the water tank and (ii) the fire suppressing agent level within the agent tank, wherein the one or more primary reducers include at least one of (i) the fuel level within the fuel tank and (ii) the active faults that are classified as serious, and wherein the one or more secondary reducers include at least one of (i) a diesel exhaust fluid level within a diesel exhaust fluid reservoir, (ii) the active faults that are classified as moderate, (iii) the maintenance being due or overdue, and (iv) the elapsed time since the fire apparatus was last exercised;

determining, by the processing circuit, a primary factor value associated with the one or more primary factors, a primary reducer value associated with the one or more primary reducers, and a secondary reducer value associated with the one or more secondary reducers;

determining, by the processing circuit, a readiness score for the fire apparatus by subtracting the primary reducer value and the secondary reducer value from the primary factor value; and

transmitting, by the processing circuit, the readiness score to at least one of (i) a display device of the fire apparatus configured to display a readiness graphical user interface including the readiness score to an operator of the fire apparatus and (ii) a remote server to be included in a comprehensive readiness report for a fleet of fire apparatuses.

11. The method of claim 10, wherein determining the primary factor value includes selecting, by the processing circuit, the lower of a value associated with the water level and a value associated with the fire suppressing agent level as the primary factor value.

12. The method of claim 10, wherein determining the primary reducer value is based on (i) an amount of the fuel tank that is empty and (ii) a predetermined value for any of the active faults that are classified as serious.
