Fig. 3 is the structural schematic diagram for the row inspection library security protection distance setting processing unit that the embodiment of the present invention 2 provides.
Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
Fig. 1 shows that the embodiment of the present invention 1 provides a kind of row inspection library security protection distance setting processing method, including：
S11, when train row inspection library track on run when, in real time obtain train the speed of service and traction acceleration.
In this step, it should be noted that there are very a plurality of tracks in row examine library.As shown in Fig. 2, each track
On can place two trains, the spacing distance L between train 1 and train 2 be train security protection distance.Train is being drawn
And braking system performance detection when, train 2 can be run to the left first, which can meet train tight
It will not bump against with train 1 after anxious braking.
In embodiments of the present invention, more rational security protection distance need to be obtained.Therefore, in train on row inspection library track
When operation, train control system can obtain the speed of service and traction acceleration of train in real time.
S12, judge the speed of service whether more than 5km/h or described traction acceleration whether more than 0.6m/s2。
In this step, it should be noted that when train the speed of service or traction acceleration respectively more than 5km/h,
0.6m/s2When, train needs emergency braking.Therefore the speed of service that needs real-time judge train current and traction acceleration and 5km/h,
0.6m/s2Size compare.
If S13, it is any be judged as YES, to train carry out emergency braking.
In this step, it should be noted that when meeting the speed of service be more than that 5km/h or described traction acceleration is super
Cross 0.6m/s2When, train control system carries out emergency braking to train.
The process of train emergency braking can be divided into three phases：
(1) first stage, train continue to accelerate.System has vehicle-mounted reaction and the time of traction cut-out to prolong before emergency braking
Late.
(2) second stage, traction cut-out, train, which is established in emergency braking in equivalent time, to be continued to slide.
(3) phase III implements emergency braking.
S14, the emergency braking information for obtaining train.
In this step, it should be noted that the emergency braking information includes the worst gradient, gyrating mass coefficient, leads
Draw cut-out delay, equivalent time and emergency braking acceleration are established in emergency braking.
S15, according to the speed of service, traction acceleration, emergency braking information and default train braking distance controlling mould
Type obtains security protection distance and exports.
In this step, it should be noted that the train braking distance controlling model includes：
Wherein, α, β are intermediate variable, and L is security protection distance, and v is maximum operational speed, and p is the worst gradient, and γ is rotation
Pignus pignoris coefficient of discharge, t0For traction cut-out delay, t1Equivalent time is established for emergency braking, a is maximum traction acceleration, ajIt is tight
Anxious braking acceleration, a1For the acceleration of emergency braking first stage, a2For the acceleration of emergency braking second stage, a3It is tight
The acceleration of anxious braking phase III.
Value in upper table is brought into the formula of above-mentioned train braking distance controlling model and be can be obtained：L=11.59m.
Train security protection distance in the library of row inspection at present on every track is 18m.It is obtained in the embodiment of the present invention
Train security protection distance is less than 12m.
Since row are examined in library there are a plurality of tracks (can reach 10-20 items), a plurality of tracks will certainly make the library in row inspection library wide
Length is very big.Therefore, only from the length for reducing train security protection distance, the length in vehicle base row inspection library is just reduced, is subtracted
The larger construction cost in few row inspection library.
