Description

Technical Field

[0001] The invention belongs to the technical field of material transportation, and in particular relates to a material tracking system and method for a suspended transportation device. Background Art

[0002] The existing collection of materials is done through collection and transfer, coiling on the core rack, vertical transportation and cooling of the materials, and then inspection, trimming, sampling, bundling, weighing, unloading and other processes are completed in sequence on the PF chain, and finally the finished materials are taken away by a forklift. In the process of collecting finished materials, it is often necessary to record the relevant information of the materials. Due to the fast pace of material production, there are often several packages of materials to be transported waiting at the same time in the collection and transportation area, so the relevant information recorded on the materials is very easy to be blurred or even confused, resulting in errors in material carding and classification storage.

The system includes a C-type hook data acquisition unit, a PF line PLC data acquisition unit, a production data query unit, a data server, and a client program in a host computer; the C-type hook data acquisition unit, the PF line PLC data acquisition unit, and the production data query unit are connected to the data server, and the client is connected to the data server; each unit transmits data through a network connection. This invention cannot track different materials, and the polling data acquisition method is relatively complicated.

[0004] The Chinese patent with publication number CN108062080A discloses a process control system for a steel coil rewinding production line. The system includes a barcode scanner, a server and a client computer. The materials on the production line are attached with barcode information to prove their identity. The barcode is attached to the surface of the materials on the production line. The barcode information of the materials is read by the barcode scanner during the steel coil rewinding production line. The barcode scanner is set on the production line and connected to the application module set in the server and sends the scanned information to the application module. The application module connects to the server and sends the read and tracked material information to the server for storage. The server is connected to the client computer for communication. The invention uses the barcode attached to the surface of the material to save the identity information of the material, which is easily affected by the external environment, resulting in damage or unreadable barcodes.
