The apparatus for detecting automatic closing function having a switching part(15), an analog-digital converter(20), an interface part(60), an establishing part(40), a display part(50), a modem part(70) and a microcomputer(30) is disclosed. The switching part(15) is connected to a track circuit to check it. The analog-digital converter(20) the transmission/receipt voltage inputted through said switching part(15) into the digital signal. The interface part(60) is connected to the A.B.S relay to check the state of it. The establishing part(40) establish the information and the basic voltage about corresponding A.B.S and track circuit. The display part(50) displays the transmission/receipt voltage of corresponding track circuit. The modem part(70) transmits said transmission/receipt voltage and the state data of the relay to the S.E.B and the analysis device. The microcomputer(30) controls said modem(70) is disclosed. Thereby, it is possible to reduce manhour costs comparing to manual type and perform accurate inspection & safe driving. |
