Abstract

A drum control system includes one or more processing circuits having programed instructions to control a drum assembly to rotate a drum at a first, unmixed speed to mix drum contents received by the drum where the drum contents including ingredients of a concrete mixture, acquire drum contents data indicative of a property of the drum contents from a mixture sensor and monitor the property of the drum contents as the drum rotates, acquire a target property for the drum contents upon delivery, determine a second, mixed speed based at least partially on the target property, and control the drum assembly to rotate the drum at the second, mixed speed in response to determining that the property of the drum contents indicates that the ingredients have been sufficiently mixed.

First claim

The invention claimed is:

1. A drum control system comprising:
one or more processing circuits having programed instructions to:
control a drum assembly to rotate a drum at a first, unmixed speed to mix drum contents received by the drum, the drum contents including ingredients of a concrete mixture;
acquire drum contents data indicative of a property of the drum contents from a mixture sensor and monitor the property of the drum contents as the drum rotates;
acquire a target property for the drum contents upon delivery;
determine a second, mixed speed based at least partially on the target property; and
control the drum assembly to rotate the drum at the second, mixed speed in response to determining that the property of the drum contents indicates that the ingredients have been sufficiently mixed.

2. The drum control system of claim 1 , wherein the one or more processing circuits have programmed instructions to:
continue to monitor the property of the drum contents while being transported to a delivery destination; and
provide a command to the drum assembly to control operation of a component of the drum assembly to affect the property of the drum contents.

3. The drum control system of claim 2 , wherein the command includes at least one of (i) a first command to control the speed at which the drum assembly rotates the drum from the second, mixed speed to a third speed or (ii) a second command to control an amount of a fluid provided into the drum.

4. The drum control system of claim 3 , wherein the command includes the first command.

5. The drum control system of claim 3 , wherein the command includes the second command.

6. The drum control system of claim 3 , wherein the command includes the first command and the second command.

7. The drum control system of claim 1 , wherein the one or more processing circuits have programmed instructions to acquire the target property from a batching system.

8. The drum control system of claim 1 , further comprising an operator interface, wherein the one or more processing circuits have programmed instructions to acquire the target property from the operator interface.

9. The drum control system of claim 1 , wherein the one or more processing circuits have programmed instructions to:
acquire at least one of (i) environment data regarding environmental characteristics or (ii) GPS data including information regarding characteristics of a route between a current location of the drum contents and a delivery destination for the drum contents; and
determine the second, mixed speed based on (i) the property at the time of determining that the ingredients have been sufficiently mixed, (ii) the target property, and (iii) the at least one of the environment data or the GPS data in an attempt to arrive at the delivery destination with the drum contents having the target property.

10. The drum control system of claim 9 , wherein the one or more processing circuits have programmed instructions to:
acquire the environment data and the GPS data; and
determine the second, mixed speed based on the environment data and the GPS data.

11. A non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by one or more processors, cause the one or more processors to:
control a drum assembly to rotate a drum at a first, unmixed speed to mix drum contents received by the drum, the drum contents including ingredients of a concrete mixture;
acquire drum contents data indicative of a property of the drum contents from a mixture sensor and monitor the property of the drum contents as the drum rotates;
acquire a target property for the drum contents upon delivery;
determine a second, mixed speed based at least partially on the target property; and
control the drum assembly to rotate the drum at the second, mixed speed in response to determining that the property of the drum contents indicates that the ingredients have been sufficiently mixed.

12. The non-transitory computer-readable storage medium of claim 11 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to:
continue to monitor the property of the drum contents while being transported to a delivery destination; and
provide a command to the drum assembly to control operation of a component of the drum assembly to affect the property of the drum contents.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the command includes at least one of (i) a first command to control the speed at which the drum assembly rotates the drum from the second, mixed speed to a third speed or (ii) a second command to control an amount of a fluid provided into the drum.

14. The non-transitory computer-readable storage medium of claim 11 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to acquire the target property from a batching system.

15. The non-transitory computer-readable storage medium of claim 11 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to acquire the target property from an operator interface associated with the drum assembly.

16. A drum control system comprising:
one or more processing circuits having programed instructions to:
control a drum assembly to rotate a drum at a first, unmixed speed to mix drum contents received by the drum;
acquire a property of the drum contents as the drum rotates;
acquire a target property for the drum contents; and
control the drum assembly to rotate the drum at a second, mixed speed in response to determining that the property of the drum contents indicates that the drum contents have been sufficiently mixed, wherein the second, mixed speed is at least partially based on the target property.

17. The drum control system of claim 16 , wherein the second, mixed speed is selected in an attempt to deliver the drum contents with the target property to a delivery destination.

18. The drum control system of claim 16 , wherein the one or more processing circuits have programmed instructions to:
monitor the property of the drum contents while being transported to a delivery destination; and
provide a command to the drum assembly to control operation of a component of the drum assembly to affect the property of the drum contents.

19. The drum control system of claim 18 , wherein the command includes at least one of (i) a first command to control the speed at which the drum assembly rotates the drum from the second, mixed speed to a third speed or (ii) a second command to control an amount of a fluid provided into the drum.

20. The drum control system of claim 16 , wherein the one or more processing circuits have programmed instructions to:
acquire at least one of (i) environment data regarding environmental characteristics or (ii) GPS data including information regarding characteristics of a route between a current location of the drum contents and a delivery destination for the drum contents; and
determine the second, mixed speed based on (i) the property at the time of determining that the drum contents have been sufficiently mixed, (ii) the target property, and (iii) the at least one of the environment data or the GPS data in an attempt to arrive at the delivery destination with the drum contents having the target property.
