Interlocking system is the key equipment of railway signaling. New-type all-electronic execution unit (AEEU) for computer interlocking system is introduced. As an example of AEEU, characters and fail-safety of DC switches execution module is discussed in detail. Then some advantages of AEEU are emphasized such as reliable, a little space equipment, powerful function, building a network conveniently, easy to maintain, automatic protection while short circuit happened and so on. At the end part of paper, applic…
