ATM simulation system is carried out in-depth researched,combining with theactual usage of the real-life ATM, stable performance of the simulation system isdesigned. The simulation system is mainly to solve ATM shortage of resources in thestudy of the process of the ATM technology or hardware failures which are difficult tosimulate, this simulation system is important for improving the efficiency and qualityof ATM.The following aspects of the content are described. First, the development andapplication of domestic and foreign ATM technology and analysis of the ATM marketare researched, by comparison of the development of domestic and foreign ATM,getting ATM market in China is uneven distribution, as well as ATM in the country hassignificant development space.Secondly, the basic mechanical structure of the ATM is introduced, ATM ’s thebasic integral modules are Ministry of pick-up,recognition unit, transmission andcassette, the cassette is divided into circulation think only a box, recycling bins andwaste cassette,and study introducedfunction and role of each module.CDS and environment of simulation system software architecture are In-depthstudied, and the function of each module and function description was studied. CDS ofthe simulation module runs under the two systems, Linux and Windows systems,respectively, under Linux system mainly completes the simulation part, under theWindows system mainly completes display section and use cases. CDS simulationsystem includes the module as a Windows service module, CAN adapter module, CANdrive module, CAN simulation module, CAN command module and CAN commandparsing module, which CAN command by simulation module CAN preprocessingmodule, CAN command processing module, CAN command distribution andprocessing module, analysis module, state change transmission module, file read submodules, and introduces the input part of the case. This paper In-depth studies CAN driving module of the simulation principle, thenmainly arguments tha the pipeline communication simulations CAN buscommunication, CAN bus communication principle, pipes, communication and how touse the pipeline communication simulation CAN communication were studied, finally,the system has been tested, After the test, verify that the system is safe and reliable, thesystem implements the functional requirements and achieves the design goal.
