【Abstract】 The several key problems about CBTC simulation implementation on the sand table are proposed,at the same time,the problems such as the detection of signal equipment,train location and wireless communication are researched,and the solution projects are proposed in this article. In research of these questions,reasonable methods are presented,and circuits are designed by comparing the several techniques,besides,the corresponding experiments are carried out.The final solution project is applied on the actual simulation sand table. The correctness of the project is verified by combining the CBTC simulation software operated the upper computer and through running a longer time. These solutions of key problems can make CBTC function simulate accurately implementation on the sand table,at the same time,it also provides some services for the teaching and training.更多还原
