Fig. 1 is a kind of flow chart for operation control method for train that the embodiment of the present invention one provides, as shown in figure 1, the party
Method includes：
Step 101, receive the first operation information that front train is sent.
Each step can be performed by current train in the present embodiment.Wherein, current train is following closely of orbiting
Train after the train of front.
In the present embodiment, the first operation information includes first position, First Speed and the first acceleration.Front train can be real
When gather the first operation information of itself, therefore first position for the first operation information of collection when front train real time position,
The real-time speed of front train when First Speed is gathers the first operation information, when the first acceleration is gathers the first operation information
The real time acceleration of front train.
Step 102, the second operation information according to the first operation information and current train, generation current train arrange with front
Time interval between car.
In this step, the second operation information of current train can be gathered in real time, the second operation information includes the second place, the
Two speed and the second acceleration.Currently can train can gather the second operation information of itself in real time, therefore the second place is collection
The real time position of current train during the second operation information, the real-time speed of current train when second speed is gathers the second operation information
Degree, the real time acceleration of current train when the second acceleration is gathers the second operation information.
Step 102 specifically may include：
Step 1021, the distance between current train and front train generated according to first position and the second place.
The distance between current train and front train are between current train and front train along the distance of track.Specifically
Ground, the distance between first position and the second place can be calculated according to the train operation trajectory diagram prestored, this first
It is the distance between current train and front train to put the distance between second place.
Step 1022, according to the first acceleration, the second acceleration, First Speed, second speed and distance, calculate the time
Interval.
Step 1022 specifically may include：
Step 1022a, formula (a is passed through2-a1)T2/2+(V2-V1) T=S calculates time result, wherein, a2 be second plus
Speed, a1 are the first acceleration, and T is time result, V2For second speed, V1For First Speed, S is distance.
Because above-mentioned formula is quadratic equation with one unknown, therefore time result can be calculated by solving the quadratic equation with one unknown
T.Following several situations be present in the time result T solved：The time result is two and two time results are all higher than 0,
Either the time result is that one more than 0 in two and two time results and another is less than 0 or time knot
Fruit is two and two time results are respectively less than 0, or the time result is without solution.
Step 1022b, time interval is drawn according to time result.
Specifically, if the time result is two and two time results are all higher than 0, chosen from two time results
Minimum value, the minimum value selected are time interval；If or the time result is one in two and two time results
More than 0 and another is less than 0, and the time result more than 0 is chosen from two time results, and what is selected is more than for 0 time
As a result it is time interval；If or the time result is two and two time results are respectively less than 0, and time interval is defined as
∞；If or the time result is without solution, and time interval is defined as into ∞.
Step 103, judge whether time interval is less than the first safe time interval pre-set, if so, then performing step
Rapid 104；If it is not, then continue executing with step 101.
If judge that time interval is less than the first safe time interval, show between current train and front train when
Between be spaced smaller, in than relatively hazardous state, but now need not also carry out brake hard, therefore perform step 104.
If judge that time interval is more than or equal to the first safe time interval, show current train and front train it

Degree of deceleration represented by information is bigger；Conversely, time interval is bigger, the degree of deceleration represented by deceleration is smaller.It is preferred that
Ground, mapping table can be pre-set, the mapping table includes the corresponding relation of time interval and deceleration, then step
In, deceleration corresponding with time interval can be inquired from mapping table.The driver of current train receives deceleration
After information, can perform with deceleration represented by degree it is corresponding deceleration.If the driver of current train before to train not
Moderating process is performed, then train is slowed down according to deceleration after receiving deceleration；If the driver of current train
Deceleration-operation is being performed to train before, then further train is being subtracted according to deceleration after receiving deceleration
Speed.In other words, no matter whether the driver of current train performs deceleration-operation before deceleration is received, and is receiving
After deceleration, it is required to slow down to train according to deceleration.If for example, degree of deceleration represented by deceleration
Small, then the driver of current train can carry out the small deceleration of degree of deceleration；If the degree of deceleration represented by deceleration is big, when
The driver of preceding train can carry out the big deceleration of degree of deceleration.So that the type of deceleration is sound as an example, if deceleration institute
The degree of deceleration of expression is small, then the sound corresponding to deceleration is small；If the degree of deceleration represented by deceleration is big, slow down
Sound corresponding to information is big.
Step 105, judge whether time interval is less than the second safe time interval pre-set, if so, then performing step
Rapid 106；If it is not, then continue executing with step 101.
If judge that time interval is less than the second safe time interval, show before current train and front train when
Between be spaced very small, in extremely dangerous state, must now carry out brake hard, therefore perform step 106.
If judge that time interval is more than the second safe time interval, show between current train and front train when
Between be spaced larger, the state in safety, and because the driver of current train at step 104 has carried out over-subtraction to train
Speed processing, brake hard can need not be now carried out, therefore perform step 101.
In the present embodiment, the second safe time interval is less than the first safe time interval.
Step 106, braking information is sent, train is braked according to braking information for the driver of current train.
Preferably, the type of the deceleration can be one or its any group in sound, bright light, image and video
Close.
