Description

Station entering and exiting control method and control system of garment production hanging equipment Technical Field The invention relates to a control method of a clothing production line, in particular to a station entering and exiting control method of clothing production hanging equipment and a control system adopting the control method. Background In recent years, the appearance of the garment production hanging assembly line thoroughly changes the traditional production mode, realizes the automatic control of the processing process, improves the production efficiency and facilitates the production management. The garment production hanging assembly line mainly comprises a closed main rail, a plurality of work stations are arranged below the main rail, work station branch rails capable of being communicated with the main rail are arranged above each work station, an inbound execution mechanism is arranged at the inbound end of each work station branch rail, the inbound execution mechanism can communicate the inbound end of each work station branch rail with the main rail, an outbound execution mechanism is arranged at the outbound end of each work station branch rail, the outbound execution mechanism can communicate the outbound end of each work station branch rail with the main rail, a plurality of push rods and clothes hangers are arranged on the main rail, and the push rods push the clothes hangers on the main rail to operate according to a specified direction under the driving of the driving mechanism. An inbound card reader is arranged on the main track in front of the inbound executing mechanism, and an outbound card reader is arranged on the workstation branch track of the outbound executing mechanism. The garment production hanging assembly line is further provided with a control center, the clothes hangers and the push rods are intelligent clothes hangers with electronic tags, and the control center reads internal information of the electronic tags on the intelligent clothes hangers through an inbound card reader and an outbound card reader to control executing actions of the inbound executing mechanism and the outbound executing mechanism. The traditional push rod positioning method needs to calculate the initial position of the whole track push rod and the offset in the motion process by means of sensor equipment such as photoelectric sensors, encoders and the like, and is high in cost and complex in calculation. The invention discloses a method for controlling the outbound of a hanging assembly line, which is disclosed in China patent with an authorized bulletin number of CN 110442101B (patent number ZL 201910724135.5), and comprises the steps of sending a signal that a clothes hanger needs to be outbound to a control center when an outbound card reader reads clothes hanger information, judging whether a push rod passing through the inbound card reader is empty or not by the control center, controlling an outbound execution mechanism to drive the clothes hanger to go out through the control information or controlling the clothes hanger to move on a main track through a communication data controller if the push rod passes through the inbound card reader, and otherwise, not going out, and stopping operation of the outbound execution mechanism after the clothes hanger is out. The method for judging whether the push rod passing through the inbound card reader is empty or not comprises the specific steps that the inbound card reader reads the push rod number passing through the inbound card reader and uploads the push rod number to a host computer of a control center, the host computer of the control center checks whether the push rod number is associated with a clothes hanger number or not, if not, the push rod is empty, if yes, the host computer of the control center judges whether the clothes hanger associated with the push rod is inbound or not, and if so, the push rod is also empty. In the above control method, there are two drawbacks: 1. The inbound card reader, the outbound card reader, the inbound executing mechanism and the outbound executing mechanism are all in communication connection with a host computer of the control center, and when the communication links are arranged, the communication link mostly adopts an RS485 communication technology or adopts a communication mode of a CAN bus and an upper computer. The communication mode has the defects of lower communication distance, communication speed and bandwidth, can not meet the communication requirements of long-distance and big data, can not realize the transmission of big files such as video, and can easily generate larger time delay in uploading and downloading communication information, particularly when any card reader fails, the control of a push rod and a clothes hanger in the whole assembly line is disordered; 2. The main circuit of the control center inquires whether the push rod number is associated with the clothes ha
