Full-digital heating control system for six-surface top press

Abstract

The invention provides a full-digital heating control system for a six-surface top press. The full-digital heating control system includes an upper computer visual monitoring system, a PLC monitoringsystem, a power controller and a high-power heating transformer. The upper computer visual monitoring system exchanges data with the PLC monitoring system through 232 serial communication. The PLC monitoring system is connected with the power controller, the power controller controls heating voltage of a synthetic block through the high-power heating transformer, a heating power signal in the synthetic block is sent to the upper computer visual monitoring system through a collecting device and a power sensor, and the power controller takes a control logic circuit module as the center. The full-digital heating control system further comprises a current detection circuit module, a control input circuit module, a synchronous detection circuit module, an overheat detection circuit module, a trigger circuit module, and an alarm output circuit module. The power controller is internally provided with an overheat detection circuit protection module, and interrupt protection and control are performed. At the same time, a hardware design is optimized to a great extent, and the cost and maintenance difficulties are reduced.

Description

technical field [0001] The invention belongs to a novel heating control system of a six-sided top press, and in particular relates to the field of full-digital heating control of a six-sided top press. Background technique [0002] At present, the heating control system of the mainstream six-sided top press is composed of scattered electrical devices, "control command signaling system", "phase-shift trigger heating control circuit board", "power transformer", "feedback transformer", "big Power thyristor module", "metal heat sink", "cooling fan", "high-power heating transformer". Heating control circuit boards are purchased outsourced, and those with self-processing capabilities generally need to design PCB printed circuit boards by themselves. After external processing, the market purchases electronic components for manual soldering, which is laborious and laborious, causing environmental pollution and harm to the human body; In addition, other components also need to be cu...

Problems solved by technology

Heating control circuit boards are purchased outsourced, and those with self-processing capabilities generally need to design PCB printed circuit boards by themselves. After external processing, the market purchases electronic components for manual soldering, which is laborious and laborious, causing environmental pollution and harm to the human body; In addition, the rest of the components also need to be customized by the market, with low efficiency, high additional cost, no automatic protection function, and the protection function needs to be used in conjunction with program software, it is difficult to find faults, and it is easily interfered by external high-frequency signals, etc.
