Brief description of the drawings
Fig. 1 is the schematic flow sheet that the row inspection storehouse security protection distance that the embodiment of the present invention 1 is provided sets processing method；
Fig. 2 is row inspection storehouse track schematic diagram provided in an embodiment of the present invention；
Fig. 3 is the structural representation that the row inspection storehouse security protection distance that the embodiment of the present invention 2 is provided sets processing unit.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the invention is described in further detail.Hereinafter implement
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 storehouse security protection distance and sets processing method, including：
S11, when train row inspection storehouse track on run when, in real time obtain train the speed of service and traction acceleration.
In this step, it is necessary to explanation, has very a plurality of tracks in row inspection storehouse.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 brakes performance detection when, train 2 can to the left be run first, the train security protection distance can meet train tight
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 storehouse track
During operation, train control system can in real time obtain the speed of service and traction acceleration of train.
S12, judge the speed of service whether more than 5km/h or described tractions acceleration whether more than 0.6m/s2。
In this step, it is necessary to explanation, when train the speed of service or traction acceleration respectively more than 5km/h,
0.6m/s2When, train needs brake hard.Therefore need the current speed of service of real-time judge train and traction acceleration and 5km/h,
0.6m/s2Size compare.
If S13, it is any be judged as YES, brake hard is carried out to train.
In this step, it is necessary to explanation, super more than 5km/h or described tractions acceleration when the speed of service is met
Cross 0.6m/s2When, train control system carries out brake hard to train.
The process of train brake hard can be divided into three phases：
(1) first stage, train continues to accelerate.System has vehicle-mounted reaction and the time of traction cut-out to prolong before brake hard
Late.
(2) second stage, traction cut-out, train is set up in equivalent time in brake hard and continues to slide.
(3) phase III, brake hard is implemented.
S14, the brake hard information for obtaining train.
In this step, it is necessary to illustrate, the brake hard information includes the worst gradient, gyrating mass coefficient, leads
Draw cut-out time delay, brake hard and set up equivalent time and brake hard acceleration.
S15, according to the speed of service, traction acceleration, brake hard information and default train braking distance controlling mould
Type obtains security protection distance and exports.
In this step, it is necessary to illustrate, 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, t0It is traction cut-out time delay, t1For equivalent time is set up in brake hard, a is maximum traction acceleration, ajFor tight
Anxious braking acceleration, a1It is the acceleration of brake hard first stage, a2It is the acceleration of brake hard second stage, a3For 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 can obtain：L=11.59m.
Train security protection distance in the storehouse of row inspection at present on every track is 18m.It is resulting in the embodiment of the present invention
Train security protection distance is less than 12m.
Due to there is a plurality of tracks (can reach 10-20 bars) in row inspection storehouse, a plurality of tracks will certainly make the storehouse in row inspection storehouse wide
Length is very big.Therefore, the length in vehicle base row inspection storehouse is just only reduced from the length for reducing train security protection distance, is subtracted
The larger construction cost in few row inspection storehouse.
A kind of row inspection storehouse security protection distance that the embodiment of the present invention 1 is provided sets processing method, by when train is in row
When being run on inspection storehouse track, the speed of service and traction acceleration of train are obtained in real time, when the speed of service is more than 5km/h or traction
Acceleration is more than 0.6m/s2When brake hard is carried out to train, so as to the train security protection more existing distance of distance for making to obtain
It is short, can to a greater extent reduce the construction cost in row inspection storehouse.
Fig. 3 shows that the embodiment of the present invention 2 provides a kind of row based on the above method and examines storehouse security protection at setting
