摘　　要：本文设计的气动发动机电控系统实现了对电磁驱动气门的有效电子控制,同时利用CAN总线建立了网络通讯平台,为系统扩展提供了便利。采用了汽车市场上广泛应用的MC9S12DP256作为ECU的核心,利用其集成的MSCAN模块通过CAN总线建立了和PC机实时快速的通讯,实现了数据的双向传输。This paper puts forward a control system for the air-powered engine, which realizes the effective control in electromechanical valve actuation. The created network communication platform, based on CAN field bus, provides the convenience for system extensions. MC9S12DP256, which is widely applied in automobile industry, is used for the core part of the ECU. By using its compositive module of MSCAN, the real-time fast communication based on CAN field bus between the PC and the ECU has been created to complete the bidirectional transmission of data.
