Abstract

A carriage system including a carriage having a target; a winch; a position sensor configured to sense a position of the target; and a controller. The winch includes a cable, a motor, and a motor sensor. The cable couples the carriage to the winch. The motor sensor senses a motor characteristic. The controller is configured to receive the motor characteristic and the position of the target, calculate a characteristic of the system, and output the characteristic.

Claims (39)

1. A carriage system comprising:

a carriage including a target;

a winch including

a cable coupling the carriage to the winch,

a motor, and

a motor sensor configured to sense a motor characteristic;

a position sensor configured to sense a position of the target; and

a controller having a memory and a processor, the controller configured to

receive the motor characteristic and the position of the target,

calculate a characteristic of the system, and

output the characteristic.

2. The carriage system of claim 1 , wherein the motor sensor is at least one selected from the group consisting of a magnetic sensor, a current sensor, and an optical sensor.

3. The carriage system of claim 1 , wherein the position sensor is an ultrasonic sensor.

4. The carriage system of claim 1 , wherein the motor characteristic includes at least one selected from the group consisting of a rotational speed and a rotational direction.

5. The carriage system of claim 1 , wherein the position is a distance between the target and the position sensor.

6. The carriage system of claim 1 , wherein the characteristic is output to at least one selected from the group consisting of a user-interface and a network.

7. The carriage system of claim 1 , wherein the characteristic is a velocity of the carriage.

8. The carriage system of claim 1 , wherein the controller further determines if the cable is broken based on a rotational direction of the motor and a direction of movement of the carriage being opposite.

9. The carriage system of claim 1 , wherein the controller is further configured to determine if an issue is present and shut down the carriage system if an issue is present.

10. The carriage system of claim 1 , further comprising

a conveyor belt; and

a conveyor take-up for collecting excess conveyor belt.

11. The carriage system of claim 10 , wherein the characteristic is a capacity of the conveyor take-up.

12. The carriage system of claim 10 , wherein the characteristic is a length of the conveyor belt in the conveyor take-up.

13. The carriage system of claim 10 , wherein the controller further determines if the conveyor belt is broken based on a rotational direction of the motor and a direction of movement of the conveyor carriage being equal.

14. The carriage system of claim 1 , wherein the carriage further includes a base rotatably supporting a conveyor belt.

15. A method of monitoring a carriage system including a carriage configured to move along the track between the proximal end and the distal end, a winch having a cable coupled to the carriage, a motor, and a position sensor, the method comprising:

receiving a position of the carriage;

receiving a rotational speed and a rotational direction of the motor;

calculating a characteristic of the carriage system, the characteristic based on

the position of the carriage,

the rotational speed of the motor, and

the rotational direction of the motor; and

outputting the characteristic of the carriage system.

16. The method of claim 15 , wherein the characteristic is a velocity of the carriage.

17. The method of claim 15 , further comprising determining if the cable is broken based on the rotational direction of the motor and a direction of movement of the carriage being opposite.

18. The method of claim 15 , wherein the characteristic is a length of a conveyor belt in a conveyor take-up.

19. The method of claim 15 , wherein the characteristic is a distance the carriage will travel before a conveyor take-up is full.

20. The method of claim 15 , further comprising determining if a conveyor belt is broken based on the rotational direction of the motor and a direction of movement of the carriage being equal.
