Refuse vehicle dump verification system and apparatus
A method and device for positively identifying that a dump event of a refuse container has occurred into a refuse hopper of a refuse vehicle are provided. When used with route software, alerts may be generated if a specific refuse container is missed or if an unexpected dump event occurs during the route.
1. A dump verification system, comprising:
a lift supported by a chassis of a refuse vehicle, the lift configured to selectively engage a container and move through a dump cycle while engaged with the container;
a data bus supported by the chassis, the data bus configured to transmit data relating to the vehicle;
a plurality of sensors supported by the chassis, the plurality of sensors comprising:
a first sensor configured to scan at least a portion of the container during the dump cycle of the lift; and
a second sensor configured to detect an angular position of at least a portion of the lift during the dump cycle; and
one or more processors configured to receive input from the plurality of sensors, execute one or more algorithms based on at least a portion of the input and data transmitted across the data bus, and determine, based on the algorithms, that the dumping cycle was performed by the lift while the container was engaged by the lift.
2. The system of claim 1 , wherein the plurality of sensors further comprises a third sensor responsive to the presence of the container engaged by the lift.
3. The system of claim 2 ,
wherein the lift comprises a crossbar extending along a width of the vehicle and a bumper supported by the crossbar, and
wherein the third sensor comprises a housing coupled to the bumper and a piston, the piston configured to, when the container is engaged by the lift, move linearly relative to the housing in response to contact with the container.
4. The system of claim 3 ,
wherein the third sensor further comprises a guide rod configured to constrain the piston to linear movement,
wherein the piston is biased against a surface of the housing by a spring coaxially aligned with the guide rod.
5. The system of claim 3 ,
wherein the third sensor further comprises a proximity switch mounted within the housing to detect movement of the piston, and
wherein the housing of the third sensor is mounted directly to the bumper, and
wherein the crossbar comprises a fork axle.
6. The system of claim 1 , wherein the data bus comprises a J1939 bus.
7. The system of claim 1 , wherein the data transmitted across the data bus corresponds to a gear position of a vehicle transmission.
8. The system of claim 1 , further comprising a converter configured to facilitate transmission of data from the data bus to a processor of the one or more processors.
9. The system of claim 1 , wherein the first sensor comprises at least one of a camera or an RFID reader.
10. The system of claim 1 , wherein the one or more processors are further configured to receive a GPS location of the vehicle.
11. The system of claim 1 , wherein the second sensor comprises a first limit switch.
12. The system of claim 11 , wherein the second sensor comprises a second limit switch.
13. The system of claim 1 , wherein the second sensor is mounted on the lift.
14. The system of claim 1 , wherein at least one of the one or more processors is supported by the chassis of the vehicle.
15. A refuse vehicle, comprising:
a lift configured to selectively engage a container and move through a dump cycle while engaged with the container, the lift comprising a crossbar extending along a width of the vehicle and a bumper supported by the crossbar; and
a sensor comprising a housing coupled to the bumper and a piston, the piston configured to, when the container is engaged by the lift, move linearly relative to the housing in response to contact with the container; and
one or more processors configured to receive input from sensor, execute an algorithm based on the input, and determine, based on the algorithm, that the dumping cycle was performed by the lift while the container was engaged by the lift.
16. The vehicle of claim 15 , further comprising a second sensor configured to scan at least a portion of the container during the dump cycle of the lift, wherein the sensor is a first sensor.
17. The vehicle of claim 16 ,
wherein the first sensor further comprises a guide rod configured to constrain the piston to linear movement,
wherein the piston is biased against a surface of the housing by a spring coaxially aligned with the guide rod.
18. The vehicle of claim 16 ,
wherein the first sensor further comprises a proximity switch mounted within the housing to detect movement of the piston, and
wherein the housing of the first sensor is mounted directly to the bumper, and
wherein the crossbar comprises a fork axle.
19. A refuse vehicle, comprising:
a lift configured to selectively engage a container and move through a dump cycle while engaged with the container, the lift comprising a crossbar extending along a width of the vehicle and a bumper supported by the crossbar; and
a plurality of sensors comprising:
a first sensor comprising a housing coupled to the bumper and a piston, the piston configured to, when the container is engaged by the lift, move linearly relative to the housing in response to contact with the container; and
a second sensor configured to scan at least a portion of the container during the dump cycle of the lift; and
one or more processors configured to receive input from the plurality of sensors, execute an algorithm based on the input, and determine, based on the algorithm, that the dumping cycle was performed by the lift while the container was engaged by the lift.
20. The vehicle of claim 19 , wherein the second sensor comprises at least one of a camera or an RFID reader.
21. The vehicle of claim 19 , wherein the one or more processors are further configured to receive a GPS location of the vehicle.
