The encapsulation technology of CPS node sensor based on UM-BUS

Uniform Model Bus (UM-BUS) is a dynamically reconfigurable high-speed BUS with address reading and writing access to the internal functional units of Cyber-Physical System (CPS) nodes. It can connect multiple CPS nodes and realize resource scheduling and method implementation by master node. There are many types and forms of sensor function methods in CPS node. In order to eliminate the operation difference of method call and make the operation equipment more convenient for users, this paper designed the packaging scheme of sensor method. It uses UM-BUS to implement layer upon layer calls between methods and can operate sensor devices without knowing the internal mechanism of CPS nodes. The simulation platform was built under Linux system for testing, and the experimental results show that the scheme can complete the optimization and encapsulation of functional methods.
