| The paper studies several key technologies about detection and control data management system at first, and on the basis of it, the computer detection and control system of navigation station is designed and developed where is Xi'an Xian-Yang international airport. This made theory applying practice successfully and the navigation station without people comes true. During studying key technologies of detection and data management system, the characters are analyzed which belong to both data type and data management of detection and control system, at the end the approach of detection and control database management system is designed. The paper discusses the techniques about not only the file structure and the record operation of database and data consistency maintenance, but also the implement of distributing disposal function which is both client and server. In the design and development of computer detection and control system of airport navigation station, the techniques of facing object and distributing database are mainly adopted. The whole detection and control software is divided into seven function modules. They are system structure module, running state of system module, setting state of system module, detection and control module, output the result of detection and control module, system exit module and system help module. They complete the display and disposal functions of detection and control data commonly. The collection and transportation of data are completed by the detection and control computer (hypogynous computer) at the navigation station. In this system, the paper discusses mainly the collection and distribution of data, conversion ways of engineering unit, display and storage of real time data and load balance technology. Finally, the whole system debugging indicates that the applying technologies are satisfied with the require of engineering and have certain advances, and a new way is provided for the management of airport modernization. |
