Abstract

A system is disclosed for monitoring waste collected by a service vehicle. The system may include a sensor configured to generate an acceleration signal indicative of an acceleration of the service vehicle, an output device, and a controller in communication with the sensor and the output device. The controller may be configured to receive the acceleration signal from the sensor after collection of the waste from a service stop. The controller may be further configured to determine an amount of the waste collected by the service vehicle from the service stop based on the acceleration signal, and to relay the amount of the waste to the output device.

Claims

1. A system for monitoring waste collected by a service vehicle, comprising:

a sensor configured to generate an acceleration signal indicative of an acceleration of a powertrain of the service vehicle;

an output device; and

a controller in communication with the sensor and the output device, the controller being configured to;

receive the acceleration signal from the sensor after collection of the waste from a service stop;

determine an amount of the waste collected by the service vehicle from the service stop based on the acceleration signal; and

relay the amount of the waste to the output device.

2. The system of claim 1, wherein the acceleration signal is associated with linear travel of the service vehicle from the service stop to a subsequent service stop.

3. The system of claim 1, wherein the acceleration signal is associated with rotation of a drivetrain component of the service vehicle during travel of the service vehicle from the service stop to a subsequent service stop.

4. The system of claim 1, wherein the acceleration signal is associated with at least one of roll, pitch, and yaw of a bed of the service vehicle during travel of the service vehicle from the service stop to a subsequent service stop.

5. The system of claim 1, further including a volume sensor configured to generate a volume signal indicative of a volume of the waste collected by the service vehicle from the service stop, wherein the controller is further configured to:

receive the volume signal from the volume sensor;

determine a type of the waste collected by the service vehicle from the service stop based on the amount of the waste and the volume of the waste; and

relay the type of the waste to the output device.

6. The system of claim 1, wherein the controller is configured to determine the amount of the waste collected only when the service vehicle is at the service stop.

7. The system of claim 6, further including a locating device configured to generate a location signal indicative of a location of the service vehicle, wherein the controller is configured to determine when the service vehicle is at a service stop based on the location signal.

8. The system of claim 6, further including a device configured to receive input from an operator indicative of a location of the service vehicle, wherein the controller is configured to determine when the service vehicle is at a service stop based on the input.

9. The system of claim 6, wherein the controller is further configured to:

link an identification of the service stop with the amount of the waste collected by the service vehicle from the service stop; and

relay the identification along with the amount of the waste to the output device.

10. The system of claim 1, wherein the controller is configured to cause the amount of the waste collected by the service vehicle to be relayed to the output device only when the amount of the waste exceeds a threshold amount.

11. The system of claim 1, wherein the sensor, the output device, and the controller are integrated into a mobile device.

12. A system for monitoring waste collected by a service vehicle, comprising:

a sensor configured to generate an acceleration signal indicative of an acceleration of a powertrain of the service vehicle during takeoff from a service stop;

a locating device configured to generate a location signal indicative of a location of the service vehicle;

an output device; and

a controller in communication with the sensor, the locating device, and the output device, the controller being configured to;

receive the acceleration signal from the sensor after collection of the waste from the service stop;

determine a weight of the waste collected by the service vehicle from the service stop based on the acceleration signal;

link an identification of the service stop with the weight of the waste collected by the service vehicle from the service stop; and

relay the weight of the waste and the identification of the service stop to the output device.

13. The system of claim 12, further including a volume sensor configured to generate a volume signal indicative of a volume of the waste collected by the service vehicle from the service stop, wherein the controller is further configured to:

receive the volume signal from the volume sensor;

determine a type of the waste collected by the service vehicle from the service stop based on the weight of the waste and the volume of the waste; and

relay the type of the waste to the output device.

14. The system of claim 12, wherein the controller is configured to determine the weight of the waste collected only when the locating device indicates that the service vehicle is at the service stop.

15. A method of monitoring waste collected by a service vehicle, comprising:

generating an acceleration signal indicative of an acceleration of a powertrain of the service vehicle after departure from a service stop;

determining an amount of the waste collected by the service vehicle from the service stop based on the acceleration signal; and

relaying the amount of the waste to an output device.

16. The method of claim 15, wherein the acceleration signal is associated with linear travel of the service vehicle from the service stop to a subsequent service stop.

17. The method of claim 15, wherein the acceleration signal is associated with rotation of a drivetrain component of the service vehicle during travel of the service vehicle from the service stop to a subsequent service stop.

18. The method of claim 15, wherein the acceleration signal is associated with at least one of roll, pitch, and yaw of a bed of the service vehicle during travel of the service vehicle from the service stop to a subsequent service stop.

19. The method of claim 15, further including:

generating a volume signal indicative of a volume of the waste collected by the service vehicle from the service stop;

determining a type of the waste collected by the service vehicle from the service stop based on the amount of the waste and the volume signal; and

relaying the type of the waste to the output device.

20. The method of claim 15, further including:

generating a location signal indicative of a location of the service vehicle;

determining the amount of the waste collected only when the service vehicle is at the service stop based on the location signal;

linking an identification of the service stop with the amount of the waste collected by the service vehicle from the service stop; and

relaying the identification along with the amount of the waste to the output device.
