Research of Intelligent On-Line Detection Equipment for Arresting Wires

The Arresting wires are the key assembly of aircraft landing system on the carrier, the most of all the current detection systems have not the ability of ration detection, and the precision of the system are low. For these deficiency, an on-line detection system for arresting wires was designed, the on-line automatic monitor algorithm, local fault (LF) algorithm were studied. The system detecting destructive by the on-scene detection mode, fast transferring the detection data to the distant PC by industry Ethernet, analyzing and processing the data by software in PC; the experiment shows that the system designed having the ability to ration assessment of LF, detection speed being fast, detection precision being high, and compliance to operational condition.

The Application Design of the Heating Boiler System

This paper introduces the design of a heating boiler control system based on PLC and IFIX. In this system, combining Premium PLC with IFIX4.5, industry Ethernet TCP/IP protocol communication is adopted to constructer the monitoring system of heating boiler though PLC and PC. Unity4.0 is used to design the ladder diagrams for the coal burning boiler to automatically realize burning process control and hearth pressure adjustment. IFIX4.5 is adopted to develop supervision control programs, which have perfect function, handy operation, fine visualization and strong man-machine interface.

Design of Ethernet-Based Constant Pressure Water Supply and Remote Monitoring System

To realize the constant pressure water supply, a frequency converter is used to control the periodic duty of three pumps in this paper. Then, the communication between host computer and field control equipment is studied and realized by using industry Ethernet Graphical control interface, and remote monitoring is realized.
