As the core equipment of decentralized autonomous Centralized Traffic Control (CTC), the decentralized autonomous computer automatically generates instructions according to the train operation plan, and sends them to the computer block interlocking system, which realizes the monitoring and control of railway station signal equipment and so on. Whether the basic data is correct or not directly affects the transportation efficiency and even endangers the driving safety. Taking the interlocking queue mapping table and interlocking route table of decentralized autonomous computer as examples, this paper develops the automatic test management system, sets up the data test environment, and realizes automatic data test. The system improves the data testing efficiency and the accuracy of the data, reduces the testing personnel’s work intensity, and provides effective technical support for the implementation of CTC system engineering.
