Hefei Metro launched a signal intelligent operation and maintenance system

Rail Transit Exhibition News The first phase of Hefei Rail Transit Line 7, which has attracted much attention, has made new progress! At present, the dynamic commissioning of the entire train has been successfully completed, and the signaling system "safety work certificate" has been obtained, and it is sprinting at full speed towards the goal of opening the initial operation.

In the early stage, we introduced you to a lot of black technology about Line 7, and today we will introduce you to a new member - "Smart Health Butler".

The real identity of this "housekeeper" is the signal intelligent operation and maintenance system, which has been deployed on the whole line and is waiting for the opening of "work" with Line 7. For Line 7, a fully automated operation line with the highest level of automation, long-term stable operation is a real test, and this "housekeeper" was born for this.

What practical effect will it bring after it goes live?

The first is that there is no need for manual 24-hour inspection. In the past, equipment that required maintenance personnel to take turns on duty and conduct regular inspections is now automatically monitored by the system, which greatly saves labor costs.

More importantly, security has been greatly improved. This housekeeper is equivalent to installing a 24-hour monitoring probe on each key equipment, and if the equipment is slightly "wrong", the system can capture and issue an alarm as soon as possible. It can not only "see", but also "understand" - through artificial intelligence analysis data, predict equipment health trends in advance, and eliminate hidden dangers in the bud.

To give a simple analogy: on existing lines, signal equipment maintenance relies more on manual regular inspections; The new housekeeper of Line 7 has changed the maintenance mode from "passive maintenance" to "active prevention". For us ordinary citizens, this means that in the future, taking Line 7, the train operation will be more reliable and stable. At present, the first phase of Hefei Rail Line 7 is in full swing to promote various work. It is expected to open for operation this year.

At present, the first phase of Hefei Rail Line 7 is in full swing to promote various work. It is expected to open for operation this year.
