Abstract

A controller may obtain, from one or more first devices of a first machine, first information regarding a load associated with a first portion of an object. The first portion, of the object, may be carried by an implement of the first machine and a second portion, of the object, may be carried by an implement of a second machine. The controller may obtain, from one or more second devices of the first machine, second information regarding an orientation of the first machine. The controller may determine, based on the first information and a threshold derived based on the second information, that a load drop condition is satisfied; perform a first action associated with dropping the load; and transmit, to the second machine, information regarding the first action to cause the second machine to perform a second action.

Claims (83)

1. A method performed by a controller of a first machine, the method comprising:

obtaining, from one or more first devices of the first machine, first information regarding a load associated with a first portion of an object,

the first machine being a first pipelayer,

the first portion, of the object, being carried by an implement of the first machine and a second portion, of the object, being carried by an implement of a second machine, and

the second machine being a second pipelayer;

obtaining, from one or more second devices of the first machine, second information regarding the first machine;

determining, based on the first information and the second information, that a load drop condition will be satisfied if one or more remedial actions are not taken; and

causing, based on determining that the load drop condition will be satisfied if the one or more remedial actions are not taken, the second machine to adjust an operation of the second machine to prevent the load drop condition from being satisfied.

2. The method of claim 1 ,

wherein the load is a first load;

wherein the method further comprises:

automatically dropping the first load based on the load drop condition being satisfied; and

transmitting, to the second machine, information regarding dropping the first load to cause the second machine to automatically drop a second load associated with the second portion of the object based on the first load being dropped.

3. The method of claim 1 , further comprising:

providing an alert indicating that a first operator of the first machine is to drop the load based on the load drop condition being satisfied; and

transmitting, to the second machine, information regarding the alert to cause the second machine to provide a notification that the alert has been provided.

4. The method of claim 1 , further comprising:

providing, after the load drop condition is satisfied, information to a device of an individual associated with at least one of the first machine or the second machine.

5. The method of claim 1 , further comprising:

obtaining third information regarding one or more operator controls of the first machine;

deriving a threshold based on the third information; and

determining that the load drop condition is satisfied based on the threshold.

6. The method of claim 1 , further comprising:

determining whether at least one of:

a pitch rate satisfies a pitch rate threshold, or

a roll rate satisfies a roll rate threshold; and

determining whether the load drop condition is satisfied based determining whether at least one of the pitch rate satisfies the pitch rate threshold or the roll rate satisfies the roll rate threshold.

7. A machine, comprising:

one or more memories; and

one or more processors configured to:

obtain:

first information, from one or more first devices of the machine, regarding a load associated with a portion of an object,

the portion of the object being carried by an implement of the machine;

second information, from one or more second devices of the machine, regarding an orientation of the machine;

determine, based on the first information and a threshold derived based on the second information, that a load drop condition is satisfied; and

perform an action associated with dropping the load based on determining that the load drop condition is satisfied,

wherein, prior to determining that the load drop condition is satisfied, the one or more processors are configured to:

determine that the load drop condition will be satisfied if remedial actions are not taken; and

perform a different action based on determining that the load drop condition will be satisfied if remedial actions are not taken.

8. The machine of claim 7 , wherein, when performing the action, the one or more processors are configured to:

provide an alert indicating that the load is to be dropped within a threshold amount of time.

9. The machine of claim 7 , wherein, when performing the different action, the one or more processors are configured to:

cause the machine to perform the remedial actions to prevent the load drop condition from being satisfied.

10. The machine of claim 7 , wherein the machine is a first machine,

wherein a first portion, of the object, is carried by an implement of the first machine and a second portion, of the object, is carried by an implement of a second machine,

wherein the action is a first action, and

wherein the one or more processors are further configured to:

transmit, to the second machine, information regarding the first action to cause the second machine to perform a second action based on the information regarding the first action.

11. The machine of claim 10 , wherein, when transmitting the information regarding the first action, the one or more processors are configured to:

transmit, to the second machine, the information regarding the first action to cause the second machine to at least one of:

provide, to a device associated with an operator of the second machine, information indicating that an operator of the first machine has been notified to drop the load,

adjust an operation of the second machine in anticipation of the load being dropped by the first machine, or

automatically drop a load associated with the second portion, of the object, being carried by the implement of the second machine.

12. The machine of claim 7 , wherein, when performing the action, the one or more processors are configured to:

provide an alert indicating that an operator of the machine is to drop the load based on the load drop condition being satisfied, and

automatically drop the load when the load is not dropped within a threshold amount from providing the alert.

13. The machine of claim 7 ,

wherein, when determining that the load drop condition will be satisfied if remedial actions are not taken, the one or more processors are configured to:

determine, based on the first information or the second information, that the load drop condition will be satisfied if remedial actions are not taken; and

wherein, when performing the different action, the one or more processors are configured to:

provide, for display, information identifying the remedial actions and information indicating that the load drop condition will be satisfied if the remedial actions are not taken.

14. A system, comprising:

one or more devices of a first machine; and

a controller, of the first machine, configured to:

receive first information transmitted by a second machine,

the first information being transmitted by the second machine based on detecting that a load drop condition will be satisfied if remedial actions are not taken;

adjust, based on the first information, an operation of the first machine to prevent the load drop condition from being satisfied;

receive second information transmitted by the second machine,

the second information being transmitted by the second machine based on detecting that a drop of a first load, being carried by an implement of the second machine, is occurring or is imminent; and

perform an action relating to a second load, being carried by an implement of the first machine, based on receiving the second information,

the first load and the second load including one or more pipeline segments, and

the action being performed based on receiving the second information from the second machine.

15. The system of claim 14 , wherein, when performing the action, the controller is configured to:

provide an alert indicating that the drop of the first load is occurring or is imminent.

16. The system of claim 14 , wherein, when performing the action, the controller is configured to:

cause the second load to be dropped.

17. The system of claim 14 , wherein, when performing the action, the controller is configured to:

drop the second load based on receiving the second information.

18. The system of claim 14 , wherein, when performing the action, the controller is configured to:

provide an alert indicating that an operator, of the first machine, is to drop the second load, and

automatically drop the second load when the second load is not dropped within a threshold amount from providing the alert.

19. The system of claim 14 , wherein the first information is transmitted prior to the drop of the first load being detected as occurring or imminent.

20. The system of claim 14 , wherein the load drop condition is satisfied when the drop of the first load is occurring or is imminent.
