Distributed Data Sample System.
There exist 4 parts, which are HMI(Humain Machine Interface) in PC, Gateway, Node, and PSD(Position Sensitive Detector) Sensor, in the system. the network topology is star network.
Each Node in the network communicate with the HMI by Gatway. Each node is linked with Gateway by CAN bus and the interface is RS232 between gateway and the PC HMI .
PC HMI collect data from all nodes by gateway, PSD sensor is connected to each node through a PSD signal transform board.
