Research Of The VHF OTE Equipment Room Card Replacement Application

East Regional Air Traffic Control Centre guard the East China provinces and one city airspace traffic safety. While the quality of very high frequency signal directly affects the efficiency of control and flight flow grasp. Because OTE VHF equipment is in a period of renewal, it is a seamless connection between the old and new versions of particular importance. In order to solve the different versions of equipment room card Compatibility. and also to save the cost and increase economic benefits. This paper presents a method to upgrade and adjust the filter system architecture type, testing and test proved the correctness and feasibility of the idea.This paper first introduces the concepts and VHF communications equipment performance DTR100and D100. Then through comparison between analysis of DTR100and D100, and test interoperability its various card module, to determine the two version of the device compatibility. Two versions of the device by the appearance observation and distinction, to determine the difference between them; through the two different versions of the device analysis of the compatibility and performance of the board compared to determine if the conversion can be done. The replacement module which can’t operate normally, this article through the software configuration and upgrading test, so that it can successfully realize the module compatibility While partial performance does not meet the aviation VHF industry standard module, it will resolve the problem through the adjustment of the system components.Results show that:the software upgrade and change the components of the system, all modules of DTR100can work in normal operation in D100, in the conservation of unit costs at the same time, can also provide more safety control work of the command.
