Description

Technical Field

[0001] The invention relates to a train signal control system, and in particular to an automatic calculation method, device and medium for the distance between a warning beacon and a restart beacon. Background Art

[0002] At present, in most subway signal systems, the point backup mode is used as a downgraded operation mode. When the continuous ATP function fails or there is a special need, the signal system will start the point backup mode to organize train operation. In the point backup mode, the on-board system controls the train operation through the trackside variable information received from the active beacon, so active beacons need to be arranged on the line. The distance between the warning beacon and the restart beacon in the active beacon needs to meet the minimum value in the real-time time parameter. If the distance between the two is too small, it means that the warning beacon is arranged too close, and the train cannot know the status of the trackside equipment such as the front signal and turnout in advance, causing the train to slow down in advance and eventually stop in front of the restart beacon, which seriously affects the operation efficiency of the train in the point backup mode. Therefore, in the system design verification stage, it is necessary to calculate the distance between the warning beacon and the restart beacon, and check that the distance between the warning beacon and the restart beacon is greater than or equal to the minimum value in the real-time time parameter.

[0003] The traditional method of calculating the distance between the advance beacon and the reopen beacon is to find the advance beacon and the reopen beacon corresponding to the signal in the backup mode variable table IBBM according to the signal machine name on the signal plan, then return to the signal plan to obtain the equipment kilometer mark corresponding to the advance beacon and the reopen beacon, and manually calculate the absolute value of the equipment kilometer mark between the advance beacon and the reopen beacon corresponding to each signal machine one by one to obtain the distance. This method requires switching back and forth between the signal plan and the backup mode variable table, which is easy to find the wrong equipment and cause distance calculation errors; and it is completely dependent on manual labor, which is time-consuming and inefficient. Summary of the invention

[0038] Step 2: Filter out the KP values ​​of all signal machines and active beacons from the equipment KP extraction table, and fill them into the DN\UP sheet of the equipment KP extraction table. Then filter out all signal machines from the DN\UP sheet and fill them into column A of the newly created Excel 1.

[0039] Step 3, based on all the signals in column A in the newly created Excel 1, search and determine in the backup mode variable table IBBM whether the signal has an associated active beacon (both the warning beacon and the restart beacon are active beacons). If not, the active beacon output in Excel 1 is empty; if yes, fill the relevant content found in the backup mode variable table IBBM into the active beacon in Excel 1;

[0040] Step 4, create Excel 2, write all the signals that can find relevant active beacons in Excel 1 into the signal column in Excel 2. Calculate the distance from each active beacon to the signal of each signal in Excel 1, and determine whether it is the minimum value. If so, this active beacon is a restart beacon, and write it into the restart beacon column in Excel 2; if not, sort from small to large according to the calculated distance, and fill the warning beacon and KP value into the warning beacon 1, KP1, warning beacon 2, KP2, warning beacon, KP3, warning beacon 4, KP4 in Excel 2 in sequence;
