A high-power intermediate frequency induction furnace data acquisition and monitoring device

Abstract

A data acquisition and monitoring device for a high-power intermediate frequency induction furnace includes a data acquisition board and an upper computer monitoring system. The data acquisition board includes a three-phase electrical parameter acquisition module, a microprocessor, an electric energy metering chip, a temperature and pressure acquisition module, a serial communication module, a pulse width modulation expansion module, an input and output module, and a relay output module. The three-phase electrical parameter acquisition module, the electric energy metering chip, and the microprocessor are connected in sequence, the temperature and pressure acquisition module, the pulse width modulation expansion module, the serial port communication module, and the input and output modules are all connected to the microprocessor, and the relay output module is connected to the input and output module connected. The host computer monitoring system communicates with the data acquisition board through the serial port, receives, displays and stores the data collected by the data acquisition board, and sends instructions to realize the control function. The invention can complete the data collection on the production site and the safety monitoring of the equipment state, and improve the reliability and automation level of the intermediate frequency induction furnace.

Description

technical field [0001] The invention relates to a monitoring technology for casting equipment, in particular to a data acquisition and monitoring device for a high-power intermediate frequency induction furnace.
