摘要
在开发电动钻机柴油发电机组数字式控制器过程中,需要实现其与电动钻机控制系统之间的通信功能。基于现场总线器件,设计一种能够实现Profibus-DP与CAN总线协议转换功能的通信单元,该单元由Profibus-DP从站接口电路和CAN节点电路组成,应用双口RAM器件实现两者之间的数据交换。该方案完善了电动钻机控制系统的总线控制方式,有利于提高产品的数字化程度。
During the development of electric drill digital diesel generater sets contruller,it needs to realize the communication function between the digital diesel generater sets controller and electric drill control system.This paper designs a communication module to achieve the protocol conversion function between the Profibus-DP and CAN bus,which is based on field bus chip.The module is composed of Profibus-DP slave station interface circuit and CAN node circuit,using doubleport RAM chip to achieve data exchange.The design improves the bus control mode of the electric drill control system and promotes the digitization degree of the product.
