A control method of a metallurgical
engineering instrument power
supply and distribution automatic design drawing
system belongs to the technical field of
engineering instrument control, and comprises the following steps: S1, reading the design input content of an engineer; s2, matching an expert
database according to the input; s3, reading the expert
database, and obtaining information of all instruments in the workshop; s4, calculating a rated current; s5, counting instruments in each power supply box according to the classification of the power supply boxes; s6, carrying out secondary distribution in the box, and carrying out classified statistics on instruments with different
voltage grades; s7, sorting instruments with the same
voltage class in the box according to power; s8, calculating the sum of the power of all instruments correspondingly supplied with power in the power supply box; s9, matching a
database, and calculating rated current of the main switch and each
branch switch in the box; and S10, naming and
pairing switch currents, and enabling the switch currents to correspond to respective instruments. According to the method, automatic drawing of the instrument power supply
system is achieved with the minimum
system input quantity to the maximum extent, the
design process is standardized, the design productivity is improved, and the
design error rate is reduced.
