Data Acquisition System Of Navigation Parameters For The Ship Model

The three waterway projects of Beijing-Hangzhou Grand Canal (Zhejiang Section) starting at the junction of Jiaxing and Jiangsu duck dam.Along the Beijing-Hangzhou Grand Canal is currently navigable south to tangqi, turned east to Bo Lu along the south junction of Yuhang, Tongxiang shed with the channel (ie, the second channel of the Beijing-Hangzhou Canal communication with Qiantang River).Passing through Hangzhou and Jiaxing borders State Road 320, Shanghai-Hangzhou Railway, Shanghai-Hangzhou Expressway, Hang Pu highway, Desheng Road and other places, and ultimately into the Qiantang River in Babao.Total length of 101.6 km.Remediation is completed, the Beijing-Hangzhou Grand Canal to reach the minimum level of three waterways,1,000-ton ship can reach Hangzhou, Zhejiang from Shandong Dongping Lake, the capacity will be increased about 40%.Data acquisition system of navigation parameters for the ship model is designed for the model test of sailing ship on single boat,towing vessels,pushers fleet in the a large majority model of export zones of BaBao. Purpose is to study to determine the routes and ship handling safety indicators when the ship through the channel (Qiantang River) exit door, Jiubao Bridge area. To help evaluate and optimize the navigation conditions improvement program for the safe navigation of the ship to provide technical parameters.Test system design of parameters of ships is researched in this paper. Deflection angle of the ship model is obtained by the test of electronic compass in this system. Then, times needed to sail responding to the deflection model are tested by subsystem control unit. After data are processed by MCU, it is transmitted to PC through wireless communication module combined with serial ports. The initial navigation path is drawn according to the speed, deflection angle and time responding to the deflection angle by PC. At Last, appropriate mathematic methods are adopted to improve the initial navigation path.This system is divided to two parts respectively named as PC control system and lower computer acquisition system. Parameters of ship model are collected by lower computer acquisition system and these data are transmitted to PC by wireless communication module. PC is the interface of control system designed by VC. Data transmitted by the lower computer are processed and saved to draw the orbit.
