Description
Technical field
The present invention relates to track traffic Servomechanism field, more particularly to a kind of automatic traveling crane test device is certainly
The dynamic field processed with man-machine interactive operation.
Background technology
Automatic traveling crane test is the operation visual plant of rail transit train, carries out automatic row according to artificial mode in the past
Car, track traffic route table generally require before runtime and are detected and updated by train control center in real time, lead to and then basis
This algorithm, makes test correctly be performed.Automatic traveling crane test is to ensure that train traffic safety, improves train conevying efficiency
Safety control system.How to ensure that reliability and safety are the premises for realizing control train Security Target.So we will
Automatic traveling crane test system is designed in terms of hardware and software two, and has been carried out experimental verification, realized system
High reliability and high security, meet the general requirement of one safety of automatic traveling crane test system failure.
According to problem above, compared to conventional traditional approach, automatic traveling crane test is more succinct and accurate, peace for the present invention
Full property is higher, starts and response time is almost nil, therefore, the present invention has more advantages in terms of automatic traveling crane.
The content of the invention
The technical problem to be solved in the present invention is：By more algorithm automatic traveling cranes test in problem, i.e., before not
Train stressing conditions, tractive force of train, train resistance, braking force of train go to produce automatic marching song line as research emphasis and are not inconsistent
Close the problem of actual rule.For solving the above problems, the present invention provides technical scheme below：A kind of automatic traveling crane test device,
It is characterized in that：
Including the range unit that tests the speed, COM1, compare harvester, path generator of driving a vehicle, minimum range intelligent decision
Device；The range unit that tests the speed calculates the present speed of train in real time and compares its permissible velocity with train under the current model
Compared with, automatic traveling crane test device control under, calculate permissible velocity in real time according to some conditions, when train speed be close to allow speed
When spending, compare harvester device and be compared；If after the time of the first sets itself, train speed is fast still above allowing
If degree, then driving path generator needs to produce road speed curve within the time of the second sets itself, that is, controls
The acceleration of train deceleration processed, minimum range intelligent decision device start minimum emergency stopping distance according to train control center, in speed
More than during permissible velocity but during deceleration automatic traveling crane test device formation speed-acceleration-when m- distance matrix,
And interaction figure is generated two-by-two, and emergency braking condition is kept until speed is reduced to less than permission according to the prediction of matrix and interaction figure
Till speed.
Description of the drawings
Fig. 1 is the system assumption diagram of the present invention；
Specific embodiment
In order that the technical problem to be solved, technical scheme and beneficial effect become more apparent, below tie
Drawings and Examples are closed, the present invention will be described in detail.It should be noted that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention, can realizes that the product of said function belongs to equivalent and improvement, include
Within protection scope of the present invention.Concrete grammar is as follows：
The present speed of train is calculated in real time and its permissible velocity with train under the current model is compared. certainly
Under dynamic driving test device control, permissible velocity is calculated in real time according to some conditions. when train speed is close to permissible velocity, from
Dynamic driving test device sends hypervelocity alarm；If after the time of sets itself, train speed is still above permissible velocity
Words, then automatic traveling crane test device needs to start brake hard within the time of sets itself. exceed permissible velocity in speed
When but during deceleration automatic traveling crane test device must keep emergency braking condition until speed reduce to less than allow speed
The advantage of the device till degree in the intelligence computation track traffic route table of present invention design mainly has：Runed and prominent according to actual
The different route tables of hair-like state generation, and the state generation redundancy route table and train of the state according to train and various equipment
Scope, so as to the reliability for improving driving includes the range unit that tests the speed, COM1 compares harvester, path generator of driving a vehicle,
Minimum range intelligent decision device；
The range unit that tests the speed in actual operation can calculate in real time the present speed of train and by its with train current
Permissible velocity under pattern is compared, and under automatic traveling crane test device control, is such as arranged according to some specified conditions
Calculating permissible velocity in real time, when train speed is close to permissible velocity, driver compares collection under certain pattern at control center
Device device is compared；If after the time of sets itself, under such as semi-artificial mode situation, train speed is still above fair
Perhaps if speed, then the driving path generator needs to produce road speed curve within the time of sets itself, also
It is the acceleration for controlling train deceleration, minimum range intelligent decision device starts minimum emergency stopping distance according to train control center, this
When to consider whether train control center will capture control, and the automatic row when speed exceedes permissible velocity but during deceleration
Car test device formation speed-acceleration-when m- distance matrix, and generate interaction figure two-by-two, according to matrix and interaction figure
Prediction keeps emergency braking condition till speed is reduced to less than permissible velocity.
The advantage of the automatic traveling crane test device of present invention design mainly has：Generated not according to actual operation and bursty state
Same matrix and interaction figure, and the state of the state according to train and various equipment produces the span of control of matrix and interaction figure,
So as to improve the reliability of driving.
