Wiring judgement control machine for wiring simulation system for verification on power transformer

Abstract

The invention discloses a wiring judgement control machine for a wiring simulation system for verification on a power transformer. The wiring judgement control machine is composed of a drive output module, an acquisition input module, a polarity and signal discrimination module, an RS232 transceiver, an MCU (microprogrammed control unit) module, a power supply unit, etc; the MCU module is in one-way connection with the drive output module, the acquisition input module, and the polarity and signal discrimination module, and is in two-way connection with the RS232 transceiver; and the whole controller adopts a digital integrated circuit, and is used for rapidly judging the wiring relationships of 48 connecting wires under the management of embedded software, and uploading the result to an upper PC (personal computer) continuously and in real time, so as to perform further processing such as a judgement about right or wrong. Via the wiring judgement control machine disclosed by the invention, an effective solution is provided for a wiring judgement for the conductor terminal of each simulator in the wiring simulation system for verification on the power transformer.

Description

[0001] technical field [0002] The invention relates to a simulation system for verification and connection of power transformers, in particular to a connection judgment control machine for the verification and connection simulation system of power transformers. Background technique [0003] The training and assessment of domestic transformer testing personnel has been in the state of manual teaching, demonstration operation, and manual assessment. In order to change this backward situation, in recent years, a power transformer verification wiring simulation system has been developed in China. Chinese patent CN 101950011 A discloses a power transformer verification wiring simulation system, which realizes computerization. In this power transformer verification wiring simulation system, it is necessary to automatically judge the on-off right-wrong relationship of the analog wiring. automatic judgment. At present, the control machine used is to use relays and some relativel...

AI Technical Summary

Problems solved by technology

At present, the control machines used all use relays and some relatively simple electronic circuits to realize judgment, so there are problems such as slow working speed, inability to collect results in real time, inconvenient expansion, inconvenient software management, and short service life.
