Real-time solution for Cyber data acquisition simulation system in petroleum industry

In order to reserve the valuable software and hardware fruits of the Cyber data acquisition system, the method of software simulation was adopted to build a simulation system on a modern high performance hardware platform. Petroleum industry's Cyber data acquisition simulation system was modeled by taking individual real devices as fundamental items and it shaped an architecture which contained a instruction-set simulator as a core, a communication bus simulation module as a bridge that connected each device simulation module. In order to meet the deadline of simulation system, its real-time performance was analyzed at length according to the average performance requirement and the worst performance requirement, and several performance parameters were extracted, then a real-time solution which based on a real-time operating system RTLinux was provided to solve the real-time communication problem between the simulation system and the real data acquisition devices.
