Modular-embedded lithium-battery-pole-piece rolling mill controller based on electrical isolation idea

Abstract

The invention discloses a modular-embedded lithium-battery-pole-piece rolling mill controller based on the electrical isolation idea. The controller comprises a control main board, and the control main board is connected with information interaction equipment through a wiring terminal; the control main board is in bidirectional communication with monitoring equipment; the control main board comprises a main control chip, a power-interface protection circuit, a main power source, an isolation power source, a communication module, a TVS self-recovery overload protection circuit, a CAN bus module, an off-chip power-down-data protection module and a measurement-and-control-signal isolation module; the main control chip is in bidirectional communication with the communication module, the off-chip power-down-data protection module, the CAN bus module and the measurement-and-control-signal isolation module through I / O pins; the main power source is in unilateral connection with the main control chip, the isolation power source and the measurement-and-control-signal isolation module. By means of the modular-embedded lithium-battery-pole-piece rolling mill controller, impacts of lightning strokes and surges to the controller can be resisted, electric equipment can be prevented from being burned out during overloading, data loss caused by sudden power losing can be prevented, and the controller can be matched with a hydraulic servo system.

Description

technical field [0001] The invention relates to a modular embedded lithium battery pole piece rolling mill controller based on the concept of electrical isolation, which is mainly used in the control system of lithium battery pole piece rolling mill equipment. Background technique [0002] Lithium batteries have the characteristics of high energy, no pollution, non-flammable and recyclable, and play an important role in national energy strategy and people's daily life. At present, the lithium battery pole piece rolling mill equipment has realized automatic high-speed production, but the embedded system controller is still immature and needs to be continuously improved.
