Embodiment Construction

[0025] According to attached figure 1 and 2 , in the clothing production line equipment control system, the computer directly monitors the main PLC, the main PLC is in the Modbus communication protocol slave station mode, correspondingly, the sub-PLC on the assembly line is in the Modbus communication protocol master station mode, and realizes the query to the main PLC. All processing stations on the assembly line are equipped with a set of equipment, and each set of equipment includes a sub-PLC, an Ethernet conversion module, a non-contact card reader, and a text operation terminal for operators to read information and perform related operations. Each PLC is equipped with an Ethernet conversion module. The total Ethernet conversion module connected to the main PLC realizes the connection conversion through the industrial switch and the Ethernet conversion module connected to each sub-PLC in the assembly line. When multiple sub-PLCs send requests to the main PLC at the same t...

Abstract

The invention discloses a method and a system for controlling garment production line equipment, wherein a sub-PLC, an Ethernet conversion module and a non-contact card reader are arranged on each processing station on a production line; a computer in a control unit directly monitors a main PLC which exchanges data with the Ethernet conversion modules in the processing stations through a main Ethernet conversion module; and an IC card is arranged on each garment hanger. When one garment hanger passes through the processing station on the production line, the non-contact card reader of the processing station reads information in the IC card and transmits the information to the sub-PLC in the processing station; the sub-PLC sends a request to the main PLC for the information in a communication mode; and the main PLC analyzes the received information and transmits a result to the corresponding sub-PLC and the computer, so that the processing position of the garment hanger is determined. The method and the system solve the problems that the communication speed between work stations and a master station during operation of the prior production line is slow, so that time-sequence competition is easy to generate and normal operation of the production line is unfavorable.

Description

technical field [0001] The invention relates to a device control method and system for a clothing production line. Background technique [0002] In the existing intelligent clothing production line equipment, the unique identifier of the hanger adopts a barcode or an ID card. Barcodes are easily contaminated or damaged in industrial sites, which causes errors in the collection of production line data. Although the ID card is also a kind of contactless card, its data cannot be changed by the user. After it is produced, it will be the only number in the world, which brings difficulties to the maintenance of the system. Workstation controller, the traditional production line is controlled by a microprocessor, that is, a single-chip microcomputer. The single-chip microcomputer is difficult to debug, inconvenient to maintain, and its stability is not as good as PLC. In the operation of the production line, the communication between the workstation and the master station is trad...
