Problems solved by technology

At the production site, since the shift needs to regularly hoist steel coils of standard weight at the Nth tracking position (that is, the installation position of the weighing machine) for weighing machine calibration, if there is a steel coil at the first tracking position at this time, the corresponding The photodetector of the Nth tracking bit sends out a light-blocking signal, and the photodetector of the Nth tracking bit has gone through a change process from non-blocking to light-blocking, so that the transmission conditions are met, thus causing the wrong transmission of the steel coil data, that is Mistakenly downloaded the standard weight steel coil data as the steel coil data on the (N-1)th tracking bit, which caused continuous error transmission of subsequent data

Embodiment Construction

[0023] The technical solutions provided by the present invention will be described in detail below with reference to specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0024] The present invention provides a leveling weighing data transmission control method, the specific steps are:

[0025] (1) Install two illuminated buttons on the main console, namely: weighing photoelectric detector lock button LOCK1 and weighing

[0026] The photoelectric detector unlocks the button UNLOCK2, inputs the button signal to the main console PLC, and modifies the main console PLC program; when modifying, it also needs to perform delay and delay filtering processing, and set the delay from 1 second to 2 seconds according to the production rhythm. second;

[0027] (2) Press the locking button LOCK1 of the weighing photoelectric detector to block the signal o...

Abstract

The invention provides a transmission control method of leveling line weighing data. The method includes the steps of adding a weighing photoelectric detector lock button LOCK1 and a weighing photoelectric detector unlock button UNLOCK2 to a master console; entering a button signal into the master console PLC, and modifying a program of the master console PLC; pressing the weighing photoelectric detector lock button LOCK1 to lock signals of a weighing photoelectric detector; calibrating a weigher via a standard weight coil; after calibration is complete and the standard coil at an N-th tracking position, namely a weighing position, is removed, pressing the weighing photoelectric detector unlock button UNLOCK2 to unlock the signals. The method is simple and effective and easy to operate, the influence of signal interference upon data transmission is lowered, and signal transmission is highly reliable.

Description

technical field [0001] The invention belongs to the technical field of accuracy and synchronous control of leveling line weighing data transmission in the metallurgical industry, and specifically relates to a method of adding signal locking and unlocking control functions to leveling line weighing data transmission, and at the same time reducing the impact of signal interference on data transmission to ensure leveling A method for error-free transmission of on-line weighing data. Background technique [0002] The currently used leveling and coiling line incorporates the current relatively advanced network technology, adopts the control of the secondary machine (Level 2), establishes communication with the primary machine (Level 1) through the Ethernet network, and realizes rolling plan preparation, roll data input and display Downloading, weighing machine data collection, printing data downloading and steel coil online tracking and other functions. The application of th...
