Abstract <br><br>computer interlocking system is to ensure driving safety signal infrastructure necessary to ensure reliable operation, and in line with "fail --- safe" principle. Basic functions interlock, complete train route established, lock, unlock, switch control, signal control, supervise and complete the track circuit signal the device status, to achieve special interlock function rail system, to ensure correct and train route train operation safety. <br>      The course of the selected station is design - a virtual station, designed to interlock content table, a table which is an expression of the interlocking relationship between all stations throughout the switch, and the signal route, which displays route switch, and the signal the basic contents of the interlock between the track sections. Table to interlock as the main route, the route point by point for an arrangement of the button is pressed, the protection signal into the passage and the display name, the route and required to check the number and location turnout locked, the route check rail circuit section name, and discharged into the passage and the apparent fill hostile signal.

Summary<br><br>Computer interlocking system is a signal base equipment to ensure the safety of driving, it must ensure reliable operation and comply with the principle of "failure --- safety". Realize the basic function of interlocking, complete the train entry, lock, unlock, fork control, signal machine control, complete the supervision of the track circuit and signal equipment status, realize the special interlocking function of the railway system, and ensure the correct train entry and the safety of train operation.<br>      This course is designed to be a station- to-propose a station, and the design content is a interlocking table, which is a table that expresses the full interlocking relationship between the entire station fork, the inlet and the signal machine, which shows the contents of the basic interlocking between the inbound fork, signal, and the track segment. Interlocking table to enter the main body, article by article to arrange the route to press the button, protection of the signal machine name and display, the entry requirements to check and lock the fork number and position, the entry road should be checked the name of the track circuit segment, and the row into the enemy signal filled out clearly.

abstract<br>Computer interlocking system is the basic signal equipment to ensure the traffic safety. It must be reliable and conform to the principle of "fault safety". Realize the basic functions of interlocking, complete the establishment, locking, unlocking, turnout control and annunciator control of train route, complete the supervision of track circuit and signal equipment status, realize the special interlocking functions of railway system, and ensure the correctness of train route and the safety of train operation.<br>In this course, the selected station is designed as a virtual station, and the design content is interlocking table, which is a table to express all interlocking relations among turnouts, routes and annunciators in the whole station, and it displays basic interlocking contents among route turnouts, signals and track sections. The interlocking table takes the route as the main body, and writes the buttons to be pressed to arrange the route, the name and display of the annunciator to protect the route, the turnout number and position to be checked and locked as required by the route, the track circuit section name to be checked by the route, and the conflicting signals with the route clearly.<br>
