Description
Technical Field
The invention belongs to the technical field of accuracy and synchronous control of leveling line weighing data transmission in the metallurgical industry, and particularly relates to a method for increasing signal locking and unlocking control functions for leveling line weighing data transmission, reducing influence of signal interference on data transmission and ensuring error-free transmission of leveling line weighing data.
Background
The leveling and coiling line used at present is integrated with the current advanced network technology, a second-Level machine (Level 2) is adopted for controlling, communication is established with a first-Level machine (Level 1) through an Ethernet network, and the functions of rolling plan programming, roll data input and display downloading, weighing machine data acquisition, jet printing data downloading, steel coil online tracking and the like are realized. The application of the advanced technologies improves the automation degree of the equipment and greatly improves the production efficiency.
The steel coil weighing machine is generally electromechanical integrated equipment, is arranged on the Nth tracking position of a stepping beam at the outlet side of a leveling coil dividing line (N is more than or equal to 3, the size of N depends on the size of a data buffer area capable of storing steel coil data in a secondary machine (Level 2) and correspondingly determines the mounting position of a weighing position photoelectric detector), is provided with a special control panel and realizes real-time communication with a PLC (programmable logic controller) through a special network. The working principle is that when weighing, the weighing machine can set and transmit parameters of finished products such as the number of a steel coil, the outer diameter of the steel coil, the production date and time and the like, and the parameters are transmitted by a secondary machine (Level 2) in an automatic state.
There are several very important conditions for the transmission of data:
1. and when the coiling drum expands and contracts once, the steel coil data waiting for weighing is stored in the data buffer. The data to be transmitted for N coils of steel can be stored.
2. The photodetector at the first tracking position of the outgoing side walking beam has a light blocking signal.
3. And the photodetector of the Nth tracking position of the outgoing side walking beam has a light blocking signal.
When the three conditions are met, the steel coil data are transmitted into the weighing machine. In a production field, because a standard weight steel coil needs to be hung on the Nth tracking position (namely, the mounting position of the weighing machine) regularly in a shift to carry out calibration operation of the weighing machine, if the steel coil exists on the first tracking position, the corresponding photoelectric detector sends out a light blocking signal, and the photoelectric detector of the Nth tracking position undergoes a change process from light blocking to light blocking, so that the transmission condition is met, and the error transmission of the steel coil data is caused, namely, the data of the standard weight steel coil is mistakenly transmitted as the steel coil data on the (N-1) th tracking position, and the continuous error transmission of the subsequent data is caused.
Therefore, the problem to be solved by those skilled in the art is urgently needed to develop a method for reducing the influence of signal interference on data transmission and ensuring error-free transmission of the weighing data of the flat wire.
Disclosure of Invention
In order to solve the problems, the invention discloses a method for increasing the functions of signal locking and unlocking control on the transmission of the leveling wire weighing data, reducing the influence of signal interference on the data transmission and ensuring the error-free transmission of the leveling wire weighing data.
In order to achieve the purpose, the invention provides the following technical scheme:
a leveling weighing data transmission control method comprises the following specific steps:
(1) install two additional buttons of taking the lamp on the master control platform, do respectively: weighing photodetector LOCK button LOCK1 and weighing
Unlocking a button UNLOCK2 by the photoelectric detector, inputting a button signal into a PLC of the main console, and modifying the program of the PLC of the main console;
(2) pressing down a LOCK button LOCK1 of the weighing photoelectric detector to block the signal of the weighing photoelectric detector;
(3) carrying out calibration operation of a weighing machine by using a standard weight steel coil;
(4) after the calibration operation is completed and the standard volume of the nth tracking bit is removed, the weighing photodetector UNLOCK button UNLOCK2 is pressed to UNLOCK the signal lock.
When the method provided by the invention is used, the previous weighing photoelectric signal is locked, and then the standard weight steel coil is used for carrying out calibration operation of the weighing machine; when the calibration operation of the weighing machine is completed, the weighing photoelectric signal is unlocked after the steel coil with the standard weight is lifted away, so that the data of the steel coil on the (N-1) th tracking position is correctly downloaded to the Nth tracking position.
Preferably, the time delay filtering treatment is required when the PLC of the master console is modified in the step (1), and the setting is carried out according to the production rhythm
Delay time 1 second to 2 seconds.
The invention also needs to modify the main control console PLC for time delay filtering processing, can prevent the weighing photoelectric detector from sending error signals when an operator or a maintenance person passes through the walking beam, and improves the reliability of the signals.
Compared with the existing data transmission method, the invention has the beneficial effects that: (1) the method is simple, effective and easy to operate; (2) the influence of signal interference on data transmission is reduced; (3) the signal transmission reliability is high.
