The Software Development Of Whole Arc Windscreen Molding Autocontrol System

Nowadays whole arc windscreen is widely used in modern operational aircraft's cockpit, it can make the pilot obtain well eyeshot, and the aircraft's performance is better than ever. As a high-tech product, whole arc windscreen's quality such as pellucidness and visual angular-deviation must be very well. The molding technology of whole arc windscreen is pivotal; the study of molding technology is a key research of avion.Presently, there are only a few developed countries have the ability of design and manufacture the whole arc windscreen, and the pivotal molding technology is strictly kept secret in these countries. Now, development of this windscreen in our country is incunabular, we get the material mostly by import, we have to develop the molding system equipment self-dependently. At first, reasonable processing method and technology must be determined. Secondly, the technology must be actualized effectively, thus autocontrol is required in the compacting process.Along with the development of microprocessor, computer and digital communication, computing control is applied to almost industry. Nonce as an all-purpose industrial control device among several kinds of computer, programmable controller (PLC) is convenient, well functional and advantageous, and it becomes a mainstay of current industrial automation. So, the realization of compacting process's automation by the use of PLC now becomes possible and promising.The project is set forth to design a suit of autocontrol system to automatize the...
