Problems solved by technology
[0004] The inventors of the present disclosure found that currently some mainstream control boards only provide protection for a limited number of signals such as coil current and DC voltage, and cannot provide comprehensive protection for the inverter system, resulting in an increase in the failure rate; most of the current protection methods use the original Some control systems collect data and trigger protection actions, which cannot realize the fault protection of their own control systems, and when the control system itself fails, it is often impossible to collect and process the fault waveform in time, which is not conducive to subsequent maintenance and processing

Embodiment 1
[0037] like figure 1 As shown, Embodiment 1 of the present disclosure provides an intermediate frequency furnace comprehensive protection system, including a processor, and the processor is connected in communication with the controller of the intermediate frequency furnace control system;
[0038] The processor judges whether to trigger the protection according to the received data of the controller and the preset threshold, and when the protection is triggered, obtains and saves the waveforms of multiple cycles before and after the triggering of the protection and the time when the fault is triggered.
[0039] In this embodiment, the processor adopts an ARM single-chip microcomputer stm32f407, and takes the ARM single-chip microcomputer stm32f407 as the core, and converts the analog signals such as coil current, capacitor voltage, and inverter voltage collected externally to A / D data and converts them into digital signals for processing. , and the protection is triggered whe...

The present disclosure provides an intermediate frequency furnace comprehensive protection system and method, the system includes a processor, and the processor is connected in communication with a controller of an intermediate frequency furnace control system; the processor is based on received data from the controller and preset threshold values After comparison, it is judged whether the protection is triggered, and when the protection is triggered, the waveforms of multiple cycles before and after the protection trigger time and the time of fault triggering are obtained and saved; the present disclosure works independently of the original control system, and the protection points are comprehensive, and can be timely in the event of a fault Cut off the power supply and record the waveform at the moment of the fault, which is conducive to the analysis of the fault cause in the subsequent maintenance process.
Description
technical field [0001] The present disclosure relates to the technical field of intermediate frequency induction melting, in particular to a comprehensive protection system and method for an intermediate frequency furnace. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The main protection points of the intermediate frequency furnace control system include coil current, coil voltage, capacitor voltage, inverter voltage, DC voltage, DC current and other signals. At present, there are many kinds of control boards for intermediate frequency furnace smelting system on the market, and the control methods are basically similar, but the protection points are very different. [0004] The inventor of the present disclosure has found that some mainstream control boards are only protected by a limited number of signals such as coil current and DC voltage, and ...
