Abstract

An apparatus and method for monitoring the productivity of a portable machine are provided. The method includes receiving motion data for at least one component of the portable machine from a multi-axis accelerometer, receiving position data for the at least one component from a process parameter sensor communicatively coupled to the at least one component, and determining, based on the received motion data and the received position data that the at least one component is oriented in a predetermined position for productive operation. The method also includes determining an area of productive operation using at least one physical dimension of the at least one component and the received motion data when the at least one component is oriented in the predetermined position for productive operation and incrementing a total area counter based on the determination.

First claim

The invention claimed is:

1. A method of monitoring productivity of a vacuum cleaning system that includes a wand assembly and a mechanical portion including a fan coupled to a motor, the method comprising:
receiving first motion data for a cleaning head of the wand assembly from a multi-axis accelerometer coupled to the wand assembly;
comparing the received cleaning head motion data to a predetermined motion threshold indicating a proper operating technique of the vacuum cleaning system;
receiving position orientation data for the cleaning head from a process parameter sensor coupled to the cleaning head;
receiving pressure data from a pressure sensor;
receiving flow data from a flow sensor;
determining, based on the received cleaning head motion data and the received cleaning head position orientation data that the cleaning head is oriented in a predetermined position for productive operation of the vacuum cleaning system;
indicating, to an operator of the vacuum cleaning system, when the cleaning head is not oriented in a predetermined position for productive operation of the vacuum cleaning system or when accelerations of the cleaning head are outside an acceleration range that indicate proper operation of the wand assembly for optimum efficiency and productivity;
receiving second motion data for the cleaning head that indicates the cleaning head is oriented in the predetermined position or that accelerations of the cleaning head are within the acceleration range that indicates proper operation;
determining a total floor area of productive operation of the vacuum cleaning system using at least one physical dimension of the cleaning head and the received cleaning head motion data when the cleaning head is oriented in the predetermined position for productive operation
at least one of scheduling maintenance on the vacuum cleaning system and replacing consumables associated with the vacuum cleaning system based on the total floor area of productive operation; and
incrementing a total floor area counter based on the determination.

2. The method of claim 1 , wherein receiving pressure data from a pressure sensor comprises receiving pressure data from the pressure sensor configured to indicate a distance of the cleaning head to a surface.

3. The method of claim 1 , wherein receiving flow data from a flow sensor comprises receiving flow data from the flow sensor configured to indicate a distance of the cleaning head to a surface.

4. The method of claim 1 , further comprising:
receiving position data in a building for the vacuum cleaning system;
determining a relative position of the cleaning head with respect to the vacuum cleaning system; and
determining a position in the building of the cleaning head using the received position data in the building for the vacuum cleaning system and the determined relative position of the cleaning head with respect to the vacuum cleaning system.

5. The method of claim 1 , further comprising transmitting an indication of the total floor area counter wirelessly to a central server.

6. The method of claim 1 , further comprising transmitting an indication of the total floor area counter wirelessly to a supervisory computer device.

7. The method of claim 1 , wherein determining a total floor area of productive operation using at least one physical dimension of the cleaning head comprises determining a total floor area of productive operation using at least a width of the cleaning head in a direction perpendicular to a direction of motion of the cleaning head.

8. A portable cleaning machine comprising:
a mechanical portion including a fan coupled to a motor and configured to generate a cleaning force;
a cleaning head comprising a first physical dimension and coupled in flow communication to said mechanical portion;
a multi-axis accelerometer positioned on said cleaning head, said multi-axis accelerometer configured to generate motion data of the cleaning head; and
a machine controller configured to:
receive motion data for said cleaning head from said multi-axis accelerometer;
compare the received motion data to a predetermined motion threshold indicating a proper operating technique of said cleaning head;
receive position orientation data for said cleaning head from a process parameter sensor coupled to said cleaning head;
receive pressure data from a pressure sensor;
receive flow data from a flow sensor;
determine, based on the received motion data and the received position orientation data that said cleaning head is oriented in a predetermined position for productive operation;
indicate to an operator of the vacuum cleaning system when the cleaning head is not oriented in a predetermined position for productive operation of the vacuum cleaning system or when accelerations of the cleaning head are outside an acceleration range that indicate proper operation of the wand assembly for optimum efficiency and productivity;
receive second motion data for the cleaning head that indicates the cleaning head is oriented in the predetermined position or that accelerations of the cleaning head are within the acceleration range that indicates proper operation;
determine a total floor area of productive operation of the vacuum cleaning system using at least one physical dimension of said cleaning head and the received motion data when said cleaning head is oriented in the predetermined position for productive operation;
at least one of schedule maintenance on the vacuum cleaning system and replace consumables associated with the vacuum cleaning system based on the total floor area of productive operation; and
increment a total floor area counter based on the determination.

9. The portable cleaning machine of claim 8 , further comprising a mechanical portion position receiver configured to determine a location within predetermined boundaries of said mechanical portion.

10. The portable cleaning machine of claim 8 , further comprising a motion and sensor processor configured to determine a location of said cleaning head within a set of predetermined boundaries.

11. The portable cleaning machine of claim 10 , wherein said motion and sensor processor is configured to map an area covered by said cleaning head based on the total floor area counter and the location of said cleaning head within a set of predetermined boundaries.

12. The portable cleaning machine of claim 8 , further comprising a motion and sensor processor configured to:
receive motion data from said multi-axis accelerometer; and
determine that the received motion data is within a threshold range of predetermined motion data.

13. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to:
receive motion data for a cleaning head of a vacuum cleaning system from a multi-axis accelerometer mounted on the cleaning head;
receive position data for said cleaning head from a process parameter sensor coupled to said cleaning head;
receive pressure data from a pressure sensor;
receive flow data from a flow sensor;
determine, based on the received motion data and the received position data that said cleaning head is oriented in a predetermined position orientation for productive operation;
compare the received motion data to a predetermined motion threshold indicating a proper operating technique of said cleaning head wherein the proper operating technique includes the received motion data being within a predetermined acceleration threshold range and said cleaning head bein
