Application of Real-Time Object-Oriented Modeling Technique for Real-Time Computer Control

摘要

This paper considers the design technique of the real-time control algorithm to implement the electronic interlocking system, which is the most important station control system in railway signal field. The proposed technique consists of the structure design and the detail design, which are based on the Real-time Object-Oriented Modeling (ROOM). The structure is designed by a modeling using the heuristic searching technique that catch and make out the specific requested condition. The detail design can be implemented if it may get the satisfied values through the repetitive modeling after comparing and examining the data obtained from the structure design for the more reliable and accurate system to be implemented. The technique proposed in this paper is implemented with C++ language that is easy to be transferred and compatible with the existing interfaces and the operating system is also designed and simulated by the VRTX that is a real-time operating system. This proposed technique is applied to the typical station model to prove the validity through verifying the performance of the modeling station.
