1. A cyber-physical system, comprising:
a plurality of target controllers, each of which includes middleware operating based on a different operating system and is configured to control a different target, the target including at least one of a sensor and an actuator; a system monitor comprising integrated middleware configured to analyze and synthesize information collected by the middleware of the target controllers, the system monitor including
a sensor registration unit that performs registration of a new sensor or actuator,a sensor release unit that performs release of an existing sensor or actuator,a sensor data acquisition unit that acquires information generated according to operation of the existing sensor from one of the target controllers that comprises middleware corresponding to the existing sensor, anda service execution unit that analyzes sensor data, that selects one service among registered services based on an analysis result, that generates a control command for executing the selected service, and that transmits the control command to the middleware of one of the target controllers corresponding to the selected service; and a virtual machine monitor configured to
form a plurality of first virtual machines by virtualizing each of the plurality of target controllers,form a second virtual machine by virtualizing the system monitor, and perform information transmission between the target controllers operating on the basis of the first virtual machines and the system monitor operating on the basis of the second virtual machine. |
