摘　　要：设计了一种适用于海上分布式多通道地震勘探仪器的实时控制系统。为了既保证系统控制的实时响应和执行能力,又保证其具备较强的灵活性,该实时系统被设计成一种分布式、层次化、异构的树状结构,控制命令的具体执行全部由硬件逻辑完成,通过优化设计的硬件逻辑状态机保证了系统响应的强实时性;设计了一种同步控制方法和严格的时序关系,保证了各分布式执行器命令执行的一致性;控制命令的分发和协议控制由软件系统完成,提高了控制响应的灵活性。室内和海上二维和三维地震采集试验证明了本文设计思路的正确性和设计方法的可行性,对其他相关控制系统设计具有一定的参考价值。A real-time control system, which is suitable for offshore distributed seismic-prospecting equip- ment with multi-channels, was designed. In order to guarantee real-time response, command execution and high flexibility, this real-time control system was designed as distributed, hierarchical and isomeric tree architecture. Command execution is performed in FPGA combined with sophisticated state machine to guarantee strict real-time performance; A synchronous control method with precise timing sequence is de- signed to guarantee the command execution synchronization; Command sending and protocol control are realized by software so as to guarantee flexibility. The validity of design thoughts and feasibility of design methods in this paper are verified by both laboratory and field 2D/3D situ-tests, and are believed to have reference value for other control system design.
