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] Such as figure 1 As shown, Embodiment 1 of the present disclosure provides a comprehensive protection system for an intermediate frequency furnace, 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 value. When the protection is triggered, it acquires and saves the waveforms of multiple cycles before and after the trigger protection time and the time of the fault trigger.
[0039] In this embodiment, the processor adopts the ARM single-chip microcomputer stm32f407, 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 into A / D data and converts them into digital signals for processing , exceeding the set threshold will t...

The invention provides an intermediate frequency furnace comprehensive protection system and method. The comprehensive protection system involves a processor, the processor is in communication connection with a controller of an intermediate frequency furnace control system, the processor judges whether protection is triggered or not after comparation between the received data of the controller with a preset threshold value, and when the protection is triggered, waveforms of multiple periods before and after the protection triggering moment and fault triggering time are obtained and stored. Thecomprehensive protection system is independent of an original control system to work, protection points are comprehensive, power supply can be cut off in time when a fault occurs and waveforms at themoment of the fault can be recorded, and fault reason analysis in a subsequent maintenance process is facilitated.
Description
technical field [0001] The present disclosure relates to the technical field of intermediate frequency induction smelting, in particular to an intermediate frequency furnace comprehensive protection system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The main protection points of the intermediate frequency furnace control system include signals such as coil current, coil voltage, capacitor voltage, inverter voltage, DC voltage, and DC current. At present, there are many kinds of control boards for intermediate frequency furnace smelting systems on the market, and the control methods are basically similar, but the protection points are quite different. [0004] The inventors of the present disclosure have found that some mainstream control boards currently only provide protection for a few limited signals such as coil curr...
