[0002] At present, in the development and use of dynamic coil ring lines, for ring line control technology, the absolute encoding system is not used but the incremental encoding system is used based on cost considerations. When using the relative encoder system, the equipment needs to return to zero at the beginning of power-on, but the actual equipment site cannot detect the position of each mover in advance, which will directly affect the return to zero operation of each mover.

[0003] At present, the operation of initializing and returning to zero for each mover requires manual intervention. Once the loop line is long and there are many movers, it is difficult to quickly return to zero in actual equipment, which affects the efficiency of returning to zero and the production of the equipment.

[0011] Wherein, after the step of moving the movers in the left-right direction to read the barcode values ​​of all movers, the method further includes:

[0012] If the barcode value of the actuator is not read, it is determined that the initialization has failed.

[0013] Wherein, the method further comprises:

[0015] Wherein, the barcode is a one-dimensional barcode strip, and the step of performing a zero return operation on each mover through a host computer program includes:

[0016] In the process of returning each mover to zero, a program for reading, analyzing, and processing the one-dimensional code of each mover is added to automatically obtain the initialization track of each mover and the sequence of each mover.

[0017] Wherein, the step of reading the barcode value of the barcode of each mover at power-on also includes:

[0018] When powered on, the subroutine associated with the one-dimensional barcode strip is called to periodically poll the drive status;

[0019] Send a barcode query command and read the barcode value of each mover's barcode through a one-dimensional code reader.

[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0032] Reference Figure 1 The present invention proposes a method for confirming the initial position of a mover of a moving coil direct drive loop line. The present invention is applied to the control technology of a direct drive loop line, such as Figure 2 As shown, a wireless communication board and a barcode reader are installed on each mover, and each mover communicates with an industrial control host computer through the wireless communication board. The method includes the following steps:

[0033] Step S1, when power is turned on and initialized, the barcode value of each mover is read, and the barcode is pre-laid in the moving direction of the mover;

[0034] Step S2, upload the barcode value of the position of the mover to the host computer through the customized wireless communication board of the mover, and the host computer program automatically determines the track where the mover is located and the sequence of each mover according to the preset range of the barcode value of each track.

[0035] Wherein, the step of reading the barcode value of the barcode of each mover when power is turned on includes:

[0036] Determine whether the barcode values ​​of all movers are read;

[0037] If not, move the mover in the left and right directions to read the barcode values ​​of all movers.

[0038] Wherein, after the step of moving the movers in the left-right direction to read the barcode values ​​of all movers, the method further includes:

[0039] If the barcode value of the actuator is not read, it is determined that the initialization has failed.

[0040] Wherein, the method further comprises:

[0041] Each mover is reset to zero through the host computer program.

[0042] Wherein, the barcode is a one-dimensional barcode strip, and the step of performing a zero return operation on each mover through a host computer program includes:

[0043] In the process of returning each mover to zero, a program for reading, analyzing, and processing the one-dimensional code of each mover is added to automatically obtain the initialization track of each mover and the sequence of each mover.

[0044] Wherein, the step of reading the barcode value of the barcode of each mover at power-on also includes:

[0045] When powered on, the subroutine associated with the one-dimensional barcode strip is called to periodically poll the drive status;

[0046] Send a barcode query command and read the barcode value of each mover's barcode through a one-dimensional code reader.

[0047] Among them, a one-dimensional code reader program is set on the wireless communication board of each mover, and the one-dimensional code value is attached to the feedback code of the mover query command according to the agreed rules, and the one-dimensional code strip laid on the track is read by the one-dimensional code reader program.

[0048] Wherein, before the step of reading the barcode value of the barcode of each mover, the step further includes:

[0049] Control the ferry boat to enable and return the ferry boat to zero;

[0050] Control the mover to enable.

[0051] The present invention uses barcode reading technology, installs a barcode reader on each mover, and automatically reads the barcode value of each mover (the barcode is pre-laid in the moving direction of the mover) at the beginning of power-on, and uploads the barcode value of the mover's position to the host computer through a customized mover communication board. The host computer program automatically determines the track where the mover is located and the sequence of each mover according to the preset range of the barcode value of each track. No manual intervention by the operator is required, and the zero return action can be quickly realized, thereby improving the zero return efficiency.

[0052] More specifically, in the present invention, the barcode is a one-dimensional code strip, and the one-dimensional code reader can be a 1600-point image sensor with a recognition accuracy of ≥5mil. It can decode conventional one-dimensional codes of various specifications and has a small size. After secondary development (the communication board adds a one-dimensional code reader program to control it), the one-dimensional code strip laid on the track can be read at any time.

[0053] The one-dimensional code tape for track laying is pre-printed on label paper or laser engraved on metal plate, and the one-dimensional code contents of 1000, 1001, and 1002 are printed vertically (perpendicular to the movement direction of the mover) in sequence. The one-dimensional code value range corresponding to each guide rail is set on the industrial computer user software (for example: 1500~2400 is the one-dimensional code value range of the upper track).

[0054] like Figure 2 As shown, each mover contains a wireless communication board and a barcode reader, and the wireless communication board serves as a wireless communication main module to communicate with the industrial computer. The tracks where the movers are located include: an upper track, a lower track, a left track, and a right track. The barcode labels are printed continuously, and the barcode value is a 4-bit value. The label value range of the left track can be 1000-1500, the label value range of the upper track can be 1501-3500, the label value range of the right track can be 3501-4000, and the label value range of the lower track can be 4001-6000.

[0055] In order to better read the barcode value of the barcode on the mover, a one-dimensional code reading program is added to the communication board of each mover, and the one-dimensional code value is attached to the feedback code of the mover query command according to the agreed rules.

[0056] On the industrial computer side, when the equipment is powered on, the host computer program adds a program for reading, analyzing, and processing the one-dimensional code of each mover to the process of returning each mover to zero through the upper computer program, so that the initialization track of each mover and the sequence of each mover can be automatically obtained without manual intervention by the operator.

[0057] The present invention also proposes a system for confirming the initial position of a mover of a moving coil direct-drive loop. The system includes a memory and a processor. A computer program is stored in the memory. When the computer program is executed by the processor, the method for confirming the initial position of a mover of a moving coil direct-drive loop as described above is implemented.

[0058] The present invention further provides a computer storage medium having a computer program stored thereon. When the computer program is executed by a processor, the method for confirming the initial position of a mover of a moving coil direct-drive loop as described above is implemented.

[0059] The present invention proposes a method, system and medium for confirming the initial position of a moving coil direct drive loop. When the power is turned on and initialized, the barcode value of the barcode of each moving element is read, and the barcode is pre-laid in the moving direction of the moving element; the barcode value of the moving element's position is uploaded to the host computer through the customized wireless communication board of the moving element, and the host computer program automatically determines the track where the moving element is located and the sequence of each moving element according to the preset range of the barcode value of each track. Thus, by using the barcode reading technology, a barcode reader is installed on each moving element, and at the beginning of power-on, the barcode value of each moving element is automatically read (the barcode is pre-laid in the moving direction of the moving element), and the barcode value of the moving element's position is uploaded to the host computer through the customized moving element communication board. The host computer program automatically determines the track where the moving element is located and the sequence of each moving element according to the preset range of the barcode value of each track. No manual intervention by the operator is required, and the zero return action can be quickly realized, thereby improving the zero return efficiency.
