Meter-based automatic metering implementation method for steel coil scale

Abstract

The invention discloses a meter-based automatic metering implementation method for a steel coil scale. A stepping beam for transporting a steel coil and the steel coil scale mounted on the stepping beam are included, a positioning device is arranged on the stepping beam, the stepping beam and the steel coil scale are electrically connected to a PLC, the PLC is connected to a weighing meter by a wire, the meter is wirelessly connected to a metering computer and a weighing system, and the stepping beam and the steel coil scale are connected to a production computer and a production system by a wire or wirelessly. A complete steel coil scale metering system designed by the method realizes the automatic metering of a steel coil and the automatic matching, storage and sharing of information; with technical means adopted by the method, the functions of steel coil metering and the complete information transmission of the steel coil are automatically completed without manual participation, avoiding information transmission errors during steel coil metering, caused by manual operation errors or delay; and the PLC and the metering computer cannot communicate directly, thereby completely avoiding virus transmission and network attacks between a production network and a metering network.

Description

technical field [0001] The invention relates to the technical field of steel coil weighing, in particular to a method for realizing automatic measurement of a steel coil scale based on an instrument. Background technique [0002] The steel coil scale is a common measurement equipment used for online measurement of steel coils transported by walking beams. It is installed in a straight section of the walking beams of the transportation line. The coil stops running and is statically weighed. After the weighing is completed, the steel coil continues to be transported by the walking beam to the next process. Due to the difference in the number and weight of the steel coil, it is necessary to accurately distinguish each steel coil, determine the blank number, weight and weighing time of the steel coil, and transmit it to other information systems as a whole for the management of steel coil measurement information with statistical analysis. The following three technical schemes ...

Problems solved by technology

The above methods need to be equipped with a large number of measurers for on-site operation, which is prone to problems such as input errors or inaccurate data confirmation.

At the same time, Plan 2 and Plan 3 need to solve the communication case between the production network and the metering network, and increase additional investment such as firewalls. At the same time, network security cannot be fully guaranteed, and the production automation system is subject to network security threats such as virus attacks.
