Developing The Data Acquisition System Of Sideslip Testing Stands Using Selsyn

This article introduces the reforming project of the system particularly. It gives us particular treatise on this three aspects, which is from the whole system construction,displacement sensor which can adjust angles itself and its peripheral circuit and software programme designing of this data collecting system. Constitution of the whole system inside highlights the rebuilding and choosing the model of equipments of topological construction of the network; The self-adjusting angles machine will be discussed particularly as the center part of reconstructed equipments contained in the system hardware and highlights the designing reconstruction of its peripheral circuit; The reforming of designing of its software programme is critical part of the system reconstrution, it must be assorted with hardware equipments rebuilding of system and upgrading of the long-distance server database system, furthermore ,the circumstance of operating system which the applying programme in will upgraded from DOS to Windows, so the programme design will change completely. The collectivity design of the software programme and all kinds of critical technics in this article are principle analyzed deeply and the depiction of the procedure of designing particularly.This sideslip detecting system is a complicated and automatic detection system. According to the applied environment of the system, the scale of application and the characteristic of business enterprise and synthesized considering from the network safety, easy maintenance and being able to expand etc, we choosed thousand trillion ether net as backbone of network(can realize to match with the framework net currently) and set up each applied son net with the fast ether net; Choose Windows 2000 to be the main server operating system so that can form a single area model Windows network; The medium and high merchandise is priority when choosing a type of PC products and the tower type of server is priority when choosing a type of server. On the design of system, I keep on the choice of the data processing equipment , network adaptor ----Network card,the media of data transferring,the equipments of network connecting,server,A/D data collection card and its definition ,the strip-code gun and the operating system. The key examination equipments of this system is a slippery detection plank, but its core parts ----the detection equipments displacement sensor is a displacement sensor which can adjust angles itself. The self-adjusting angles machine is used to detect the slippery displacement in the equipment of slippery detection in slippery unit. This self-adjusting angles machine used in this system is three graphs moment type of machine. This three graphs moment type of self-adjusting angles machine is always used in situation which the power is rather powerful, so called electricity stalk system. The moment type of self-adjusting angles machine is an open-ring system, being fitted for the control system which requires low angle-transferring precision, and it requires light weight,small cubage,high precision and long life. The programme design of this system is the important part of this system. Include the work procedure, function demarcation of the system and the key technique of the designs, and how to test the software function experimentally at last. The main function of the system programme is to process the data come from the slippery detection console, then show at the native terminal display, providing the examination worker at slippery unit to look over, and transmit the processed data to database on long-distance server in main controlling room and estimated, authorized,printed and so on by the detecting system programme on the server finally.
