Description
Technical field
The utility model relates to a kind of converter tilting control device, belongs to converter control technical field.
Background technology
In the converter tilting system of steelworks, the control of converter inclining angle is by master controller, and production link fascinates and carries out manual operation by range estimation.Above-mentioned command signal is passed to PLC, by PLC, give to control that motor accelerates and deceleration reaches converter inclining proper angle and locates, and blows or taps, slags tap, the technological operation such as filler, thermometric, sampling.Because master controller make-position inaccurate caused rifle difficulty under oxygen rifle, cannot blow; When operation is fascinated in range estimation, because environment is severe, flue dust large, range estimation is forbidden easily to cause the steel that inclines, the serious accidents such as slag of inclining.
Utility model content
The purpose of this utility model is to provide a kind of converter tilting control device, to can be controlled for converter inclining, to reduce the harm causing in converter inclining process, convenient production control.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of converter tilting control device, comprise single-chip microcomputer 89C51, on single-chip microcomputer 89C51, be connected with signal input preposing signal process circuit, outputting circuit for relay, analogue quantity output circuit, watchdog reset circuit, serial interface circuit, keyboard input circuit, numerical value display circuit, duty display circuit and oscillatory circuit; On serial interface circuit, be connected with special aobvious device; On analogue quantity output circuit, be connected with host computer; On single-chip microcomputer 89C51, be connected with the photoelectric encoder being arranged on converter device.
Further, photoelectric encoder is arranged on coming out of the stove on axle of converter.
Further, single-chip microcomputer 89C51 is arranged in converter operation room.
Further, special aobvious device is LED display, is provided with two, is arranged on respectively converter operation room and converter on-the-spot.
It is input pickup that this utility model device adopts photoelectric encoder, by signal input preposing signal process circuit, outputting circuit for relay, analogue quantity output circuit, watchdog reset circuit, serial interface circuit, keyboard input circuit, numerical value display circuit, duty display circuit and special aobvious installation composition.According to the actual conditions of converter system, a photoelectric encoder has been installed on converter shaft, in converter operation room, single chip computer device is installed.Single-chip microcomputer is got the pulse signal that photoelectric encoder transmits and is converted to the real-time angle of digital quantity signal output display.Some switching value output is established at important converter inclination angle again, for controlling and reporting to the police.Single-chip microcomputer is that 4-20mA electric current or 0-10V voltage signal are exported to host computer by digital quantity signal by D/A circuit conversion simultaneously, or digital quantity signal is passed to host computer by serial communication port (RS-485 or RS-232).Host computer can be made real-time turning angle curve map with the real-time change of record analysis converter inclining angle according to the angle signal transmitting.For making operator can see clearly that real-time angle has respectively added a spy aobvious (LED) device after pulpit and stove.Operator shows shown real-time angle by spy can better control fascinating of converter angle, thereby has greatly reduced the accident occurring in converter inclining process.Once and have an accident, the real-time turning angle curve map that host computer is done can be used to the reason that analysis accident produces, and understands fully accident responsibility.
The beneficial effect of this utility model is: the utility model device has and shows real-time angle, analog output, relay output, digital output serial communication, the special function such as show, and effectively converter inclining has been carried out to monitoring and protection.This utility model device can be optimized the production operation time, realizes turning angle protection and monitoring, has improved production efficiency, has reduced failure rate.
