Crystallizer vibration control device based on CAN bus

Abstract

The invention discloses a crystallizer vibration control device based on a CAN bus. The crystallizer vibration control device is a crystallizer hydraulic vibration control device which is low in cost and is provided with a field bus interface, is used for constructing a multi-strand casting machine vibration control system based on a CAN field bus and is of great significance for improving the present situation of mostly introducing hydraulic vibration control devices used by domestic iron and steel enterprises from abroad, reducing continuous casting automation cost and improving continuous casting automation level. An STM32 single-chip microcomputer servers as a controller, and system costs are greatly reduced. SSI signals can be adopted in the aspect of vibration displacement detection, high-speed synchronous sampling of vibration displacement signals can be achieved, and vibration displacement detection accuracy can be improved simultaneously; in the aspect of communication, the crystallizer vibration control device is in communication with an upper computer through the CAN bus, and functions of real-time modification and monitoring of vibration waveform parameters can be achieved.

Description

technical field [0001] The invention relates to a crystallizer vibration control device based on a CAN bus, in particular to crystallizer vibration control and belongs to the field of continuous steel casting. Background technique [0002] At present, the hydraulic vibration control devices used by domestic iron and steel enterprises have the following defects: [0003] 1) Most of the vibration controllers with relatively complete functions are imported from abroad, and the cost is very high; [0004] 2) Some low-cost crystallizer vibration controller field-level equipment only has the function of signal acquisition and execution of control commands. The control algorithm is completed by the upper computer, and the function of the lower computer is only to collect and execute the commands of the upper computer. Communication in the bus Inability to complete work tasks in the event of failure; [0005] 3) Many current low-cost controllers have deficiencies in the modificati...
