Computer monitoring system control method for electric melting furnace

Abstract

The invention discloses a computer monitoring system control method of an electric melting furnace in the field of computer monitoring technology. The specific steps of the computer monitoring system control method of the electric melting furnace are as follows: S1: start the monitoring system: input in the host computer according to the actual production on site Initial process parameters, start the computer monitoring system of the fused magnesium furnace, the initial process parameters include the particle size of raw materials, the length of smelting time, which equipment to produce, the size of the voltage and the size of the smelting current; S2: data sampling: programmable The controller performs A / D conversion on the current sampling data from the current transformer, simultaneously samples the output data of each button and the control motor, and transmits the sampled data to the host computer through the network through the communication module; S3: storage comparison : The configuration software of the upper computer writes the current sampling data transmitted by the lower computer, the data of each button and the output data of the control motor into the database, and uses this to make the trend diagram of the current value in the actual production on site and the actual production process on site screen.

Description

technical field [0001] The invention relates to the technical field of computer monitoring, in particular to a control method for a computer monitoring system of an electric melting furnace. Background technique [0002] The magnesium melting furnace uses a programmable controller as the main control unit, and a non-contact switch as the actuator to realize multi-faceted and reliable automatic control. The automatic control device of the fused magnesium furnace includes: a host computer, a printer, a programmable logic controller PLC, an operating table, a current sampling and channel switching part, and an actuator. The device has remote monitoring, start / stop furnace control, manual / automatic conversion, current setting value setting, real-time current value histogram and digital display, power statistics of each furnace, timing, automatic exhaust, fault self-diagnosis, etc. Features. The on-site operation is stable and reliable, the response speed is fast, the life is l...

Problems solved by technology

With the development of computer technology, the operator cannot understand the production status in the fused magnesium furnace, the process cannot automatically find the optimal smelting current value, the historical status is unknown, the entire production process cannot be tracked, the self-diagnosis of equipment failure is not good, and manual production The labor intensity is high. Therefore, we propose a computer monitoring system control method for electric furnaces to solve the above problems.
