Adaptive motion control for carriage printer
View Patent ↗A method of adaptively controlling motion of a carriage in a carriage printer within a user's environment, the method includes controlling a motor to move a carriage of a carriage printer within a user's environment according to a first motor control profile; acquiring data relative to a motion of the carriage printer as the carriage is moved according to the first motor control profile; analyzing the acquired data relative to the motion of the carriage printer corresponding to the carriage being moved according to the first motor control profile; and controlling the motor to move the carriage of the carriage printer according to a second motor control profile.
1. A method of adaptively controlling motion of a carriage disposed within a housing in a carriage printer, the method comprising:
controlling a motor to move the carriage back and forth along a carriage guide rail disposed within the housing of a carriage printer according to a first motor control profile;
acquiring data relative to a motion of the carriage printer as the carriage is moved according to the first motor control profile;
analyzing the acquired data relative to the motion of the carriage printer corresponding to the carriage being moved according to the first motor control profile; and
controlling the motor to move the carriage of the carriage printer according to a second motor control profile, which minimizes an amount of motion of the carriage printer caused by the carriage moving back and forth along the carriage guide rail.
2. The method according to claim 1 , wherein the second motor control profile results in a reduced amount of motion of the carriage printer compared with an amount of motion of the carriage printer resulting from the first motor control profile.
3. The method according to claim 1 further comprising:
acquiring data relative to a motion of the carriage printer as the carriage is moved according to the second motor control profile;
analyzing the acquired data relative to the motion of the carriage printer corresponding to the carriage being moved according to the second motor control profile; and
when the motion of the carriage printer is determined to still be excessive, controlling the motor to move the carriage according to a third motor control profile, which further minimizes an amount of motion of the carriage printer caused by the carriage moving back and forth along the carriage guide rail.
4. The method according to claim 1 further comprising attaching a motion detector to the carriage printer to acquire data corresponding to motion of the carriage printer.
5. The method according to claim 4 , wherein attaching the motion detector to the carriage printer further includes attaching an accelerometer to the carriage printer.
6. The method according to claim 4 , wherein attaching the motion detector to the carriage printer further includes attaching an optical sensor to the carriage printer.
7. The method according to claim 4 , wherein attaching the motion detector to the carriage printer further includes detachably attaching the motion detector to the carriage printer.
8. The method according to claim 7 , wherein detachably attaching the motion detector to the carriage printer further includes temporarily mounting a mobile communication device on a housing of the carriage printer.
9. The method according to claim 8 , wherein acquiring data relative to the motion of the carriage printer further includes transmission of data from the mobile communication device.
10. The method according to claim 9 , wherein analyzing the acquired data further includes transmission of data from the mobile communication device to a remote server and using the server to analyze the acquired data.
11. The method according to claim 1 further comprising providing motor control profile selection guidance for selecting the second motor control profile based on the analyzed data relative to the motion of the carriage printer corresponding to the carriage being moved according to the first motor control profile.
12. The method according to claim 11 , wherein the motor control profile selection guidance includes a table.
13. The method according to claim 1 , wherein analyzing the acquired data includes performing a fast Fourier transform of the acquired data to provide a vibration frequency spectrum.
14. The method according to claim 1 further comprising suppressing a resonant vibration of a coupled system that includes the carriage printer and the user's support unit for the carriage printer.
15. The method according to claim 1 , wherein a travel time of the carriage corresponding to the second motor control profile is substantially the same as a travel time of the carriage corresponding to the first motor control profile.
16. The method according to claim 1 , wherein controlling the motor to move the carriage according to the first motor control profile includes:
accelerating the carriage to move in a first direction; and
decelerating the carriage to a stop.
17. The method according to claim 16 , wherein controlling the motor to move the carriage according to the first motor control profile further includes:
accelerating the carriage to move in a second direction that is opposite the first direction; and
decelerating the carriage to a stop, thereby completing a carriage motion cycle.
18. The method according to claim 17 , wherein controlling the motor to move the carriage according to the first motor control profile further includes accelerating and decelerating the carriage for a plurality of carriage motion cycles.
19. The method according to claim 1 further comprising sensing an amount of ink.
20. The method according to claim 1 further comprising displaying a message to the user regarding a support unit for the carriage printer.
