Design and Implementation of Mobile Terminal Supervisory System Based on Networked Control Systems

The networked control system includes controllers, actuators and sensors, information is exchanged among every part via the network. To solve the problem that the information monitoring must depend on PC, a mobile terminal supervisory system based on Networked Control systems is introduced in this paper. It is a real-time platform to monitor the realistic performance of the networked control systems. The system adopts a more universal hardware platform: mobile phone, which is compact, low-cost and resourceful. In this paper, client/server architecture of this system is described. The stability and richly functional controls are integrated into the system, which meet the requirement of customize supervisory interface and improve the reliability of systems. The system also supports tuning parameters online to achieve consecutive observation through the duplex channel based on TCP/IP protocol. In this paper we illustrate the overall framework and details and its potential applications. Finally, for the air-hearing simulation system, the networked control based experiment demonstrate the feasibility and practicability of the designed system.
