Soft Count Down Time Generation and Dissemination System Over LabVIEW Environment

Count Down Time (CDT) and Accumulated Time of the Day (ATD) are essential parameters for any flight testing in a test range. Conventional CDT systems are hardware based and are bulky, costly and very difficult to reconfigure. Soft CDT system is an alternative system having all the functionalities of the existing CDT system. Ethernet based communication is used to overcome the inherent problems associated with the serial communication in the existing system. The system is designed over PC based platform in LabVIEW environment to provide simplified, reconfigurable and easy to handle CDT scheme. High speed video test results are carried out to verify the delay attributed to Ethernet communication in the proposed system.
