摘要
介绍电液式阀门的工作原理以及在船舶实际使用中存在的问题,设计了基于CAN总线技术的阀门控制器。该阀门控制器采用P87C552单片机,通过SJA1000实现CAN总线的功能。它接受上位机的控制信号,控制执行机构中电机正反转,实现对电液式阀门的开启与关闭控制,同时实时采集电机的电流信号和阀门的位置信号。所有的信息均通过CAN总线反馈给上位机。基于CAN总线技术的智能电液阀门控制系统与传统的电液阀门控制系统相比,可以避免阀门的布线问题。
The principle of electro-hydraulic valve was analyzed, and the problems in practical use in ships were presented. A new control system of electro-hydraulic valve based on CAN bus was introduced. The valve controller was designed based on CAN bus. MCU of Philips 87C552 and SJA1000 were used to achieve signal communication. The valve controller received the control signals from host computer to control positive and negative rotation of the motor in the executive body and the startup and shutdown of valve could be realized. Sim^taneously, the current signal of the motor and position signal of the valve were collected . All of the signals were fed back to host computer by CAN bus. Compared with the traditional electro-hydraulic valve control system, this new control system can avoid wiring.
