摘　　要：为了解决当前电动执行器的现场总线接口标准单一,兼容性差的问题,研究集成多种现场总线的方法,实现异构网络的通信互连.选择在电动执行器中集成PROFIBUS-DP和CAN总线,并在此硬件基础上,研究兼容数据网关功能的方案,使电动执行器不仅能在这两种总线网络中应用,而且可以解决CAN总线网络与PROFIBUS总线的连接,最后通过与和利时的控制系统联机,测试了现场总线接口的功能,验证了方案的可行性.In order to solve single interface and poor compatibility of field bus of the electric actuator at present, the paper studies the method of integrating a variety of field bus to achieve the communication of heterogeneous networks. The paper chooses to combine PROFIBUS - DP with CAN in the electric actuator, and studies the functions of compatible data gateway based on the hardware, which make the electric actuator not only be used in the two kinds of field bus but also solve the problem of combining CAN with PROFIBUS. Finally, by connecting with the control system made in HOLLIAS Company, the functions of field bus communication are tested, and the feasibility of the design is verified.
