[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0061] Figure 1 is a flow chart of a method for confirming the opening speed and monitoring position of a train control onboard device provided in an embodiment of the present invention, and Figure 2 is a schematic diagram of a train and point structure provided in an embodiment of the present invention. As shown in Figure 1, the method for confirming the opening speed and monitoring position of a train control onboard device in an embodiment of the present invention, specifically the method for confirming the opening speed and monitoring position of a train control onboard device based on ETCS, includes the following steps:
[0062] Step S101: Obtain the original opening speed V between the trip location and the monitoring location (SvL) r .
[0063] As shown in Figure 2, train 1 travels from left to right, following the arrow. When stopping at Clearance End 1, train 1's actual resting position is often still some distance away from Clearance End 1 due to factors such as speed measurement errors, distance measurement errors, and stopping accuracy. The European Train Control System (ETCS) incorporates an opening speed feature, which allows the train to pass Clearance End 1 at a lower speed (the opening speed) without exceeding Supervisory Position 4. ETCS calculates this opening speed based on Supervisory Position 4 and Clearance End 1.
[0064] Overrun Protection Position 2 is the position of Train 1 on the track when the overrun protection function is activated. The area where Train 1 travels with the overrun protection function activated is called the protection overlap. Supervision Position 4 marks the end of the protection overlap. If there is no danger point in the protection overlap, Supervision Position 4 is the location of the danger point.
[0065] The over-advance protection position 2 is the sum of the End of Movement Authority 1 (EOA) and the ranging error, that is, the over-advance protection position 2 is obtained by adding the EOA to the ranging error.
[0066] Specifically, step S1011: constructing an emergency brake intervention curve (EBI) and an emergency brake deceleration curve (EBD) between the over-advance protection position and the supervision position.
[0067] The track information between the over-advance protection position and the supervisory position is obtained, such as the track's slope, viscosity, and braking type (regenerative braking, eddy current braking, magnetic track braking, etc.); the emergency braking intervention curve and the emergency braking deceleration curve are calculated, taking the over-advance protection position as the starting position and the supervisory position as the ending position, with a speed of 0 km / h at the end. Taking the track information into consideration, the emergency braking intervention curve and the emergency braking deceleration curve are calculated. The establishment of the emergency braking intervention curve and the emergency braking deceleration curve can be done using existing technology. The method for constructing the curve is not the subject of this invention and is not described in detail here.
[0068] Step S1012: Obtain the first speed V corresponding to the over-advance protection position on the emergency braking intervention curve r1 .
[0069] In the above embodiment, the specific over-advance protection position has been obtained, and the corresponding first speed V can be obtained by simply searching in the emergency braking intervention curve. r1 .
[0070] Step S1013: Based on the first speed V r1 , determine the moving distance D1 within the traction delay T1 and the braking delay T2. This process can be expressed by formula (1). D1=(T1+T2)*V r1 (1)
[0071] Step S1014: Based on the trip location and the moving distance D1, determine the first position P2. This process can be expressed by formula (2). P2 = trip location + D1 (2)
[0072] Step S1015: Determine the second speed V corresponding to the first position P2 on the emergency braking deceleration curve r2 Using the emergency braking deceleration curve constructed in step S1011, the second speed V corresponding to the first position P2 is found in the corresponding middle curve. r2 .
[0073] When the first speed V r1 With the second speed V r2 When the deviation is less than the speed deviation threshold, the first speed V r1 Confirmed as the original opening speed Vr; or when the first speed V r1 When the deviation from the second speed is greater than or equal to the speed deviation threshold, the second speed V r2 Confirmed as the original opening velocity Vr.

Establishing the first common braking intervention curve can be done using existing technology; the method for constructing the curve is not covered by this invention and is not described in detail here.

In the first common braking intervention curve, the original opening speed V can be found through the horizontal and vertical coordinates in the curve graph. r The corresponding second position P3.
[0079] Step S1023: Construct a second custom braking intervention curve between the estimated front end of the train and the permitted end point. Track information between the estimated front end of the train and the permitted end point is obtained, such as track slope, viscosity, and braking type (regenerative braking, eddy current braking, magnetic rail braking, etc.). The second custom braking intervention curve is calculated, taking the estimated front end of the train as the starting position and the permitted end point as the ending position, with a speed of 0 km / h at the end, while also considering the track information. The second custom braking intervention curve can be established using existing technology. The method for constructing the curve is not covered by this invention and is not described in detail here.

[0082] Step S103: Obtain the minimum speed limit V in the first list between the original monitoring position P1 and the over-advance protection position in the speed limit list (MRSP). ri MRSP is the most stringent speed limit section on the train running line, which stipulates the speed that the train cannot exceed during operation. Traverse the speed limit list (MRSP) and find the minimum speed limit between the original monitoring position P1 and the over-advance protection position.

[0083] Step S104: Based on the original opening speed V r and the minimum speed limit V in the first list ri , determine the actual opening speed V and the actual monitoring position P.
[0084] Specifically, when the original opening speed V rLess than the minimum speed limit V in the first list ri When the original opening speed V r The actual opening speed V is confirmed, and the original monitoring position P1 is confirmed as the actual monitoring position P.
[0085] Or when the original opening speed V r Greater than or equal to the minimum speed limit V in the first list ri When the minimum speed limit V in the first list is ri Confirmed as the actual opening speed V, based on the minimum speed limit V in the first list ri Determine the actual monitoring position P.
[0086] The specific steps include:
[0087] Step S1041: Obtain a speed limit list (MRSP) between the third position P4 and the over-advancement protection position. A speed limit list includes the original monitoring position P1, the third position P4 and the over-advancement protection position.
[0088] Step S1042: Obtain the minimum speed limit V in the second list of the speed limit list mrsp The list position P5 corresponds to the minimum speed limit in the second list. Traverse the speed limit list (MRSP) and find the minimum speed limit. This minimum speed limit is called the minimum speed limit V in the second list. mrsp , and the minimum speed limit V in the second list mrsp It is possible to maintain a certain distance and take the list position P5 corresponding to the start of the minimum speed limit in the second list.

[0090] Or when the original opening speed V r Greater than or equal to the minimum speed limit V in the second list mrsp When the minimum speed limit V in the second list is mrsp Confirmed as the actual opening speed V, based on the minimum speed limit V in the second list mrsp Determine the actual monitoring position P.
[0091] In one embodiment, the minimum speed limit V in the second list is implemented by the following steps: mrsp Determine the actual monitoring position P. Specifically include:
