Integrated design of monitoring and controlling system for airfield lighting based on local network

The airfield lighting monitoring and controlling system is developed in order to eliminate the deficiency of manually monitoring and controlling the airfield lighting, to improve the efficiency, the reliability and the rapidity of the system, and to realize nationalization and modernization of the airfield systems. Various technologies of hardware, software and network are used in ths system to realize sending and receiving in the network of the system in real time, to achieve the monitoring and control the airfield light and the status of the failure and the fire alarm timely, to backup the data and operational commands using the SQL server 7.0 database. A self checking technique is also utilized to fulfill the requirement of reliability and maintenances. In software design, three programs are developed for the lighting control, electric power monitoring, diesel engine monitoring and controlling separately. The three programs are running independently in same time. The paper also presents the composition method of the system, gives the design scheme of the software, hardware and man machine interface and some solutions of actual problems in the development and application from the programming experience by the authors.
