Abstract
The present invention belongs to the field of railway system and railway track structure and relates to a railway curve segment superelevation of outer rail intelligent system. The intelligent system real-timely adjusts the superelevation of outer rail to fit the need of superelevation of outer rail of trains at different speeds. The intelligent system comprises a speed detecting device, a central processing system, a superelevation of outer rail adjusting device and a monitoring device. The principle is as follows: the speed detecting device is arranged in a straight line segment before the railway enters the curve segment, which detects the speed of the train which is about to travel into the curve segment and sends the speed to the central processing system. The central processing system works out a needed value of the superelevation of outer rail according to the speed and sends an order to the superelevation of outer rail adjusting device which is arranged on the curve segment. The superelevation of outer rail adjusting device completes the adjustment of superelevation of outer rail according to the order and before the train travels into the curve segment. When the train travels through, the monitoring device real timely monitors traveling state of the train and sends information to the central processing system. The central processing system judges whether the value of the superelevation satisfies the need of train traveling according to the information and when necessary the central processing system sends the order to adjust the superelevation.
Description
Technical field
The invention belongs to the railway system (B61B1/00), railway track structure (E01B2/00) field, particularly the railway curve section is regulated the intelligence system of superelevation of outer rail.
Background technology
On railway curve, outer side track need be provided with the effect of superelevation with equilibrium centrifugation power.The size and the road speed of centnifugal force are proportional, and with the radius of curve relation of being inversely proportional to.In theory, should corresponding superelevation be set according to different lines vehicle speed and radius of curve.In the present railway system, in fact usually the average velociity with the various trains that move on the circuit serves as according to the superelevation value is set.Therefore, high speed train the superelevation phenomenon occurs owing during by curve, and there was superelevation in the low speed train during by curve, the railway of passenger-cargo conllinear, and this problem is particularly outstanding.Cross superelevation, owe superelevation and all influence the stationarity of train operation, passenger's comfort level, even influence traffic safety.
Summary of the invention
By being installed in the intelligence system of railway curve section, adjust the superelevation of outer rail value in real time, with the train that adapts to friction speed needs, guarantee train safe, smooth running to superelevation of outer rail.
This intelligence system comprises: speed detector (A), central processing system (B), superelevation of outer rail control apparatus (C), control monitor unit (D).
Principle of work: installation rate detecting device on the linear portion before circuit enters curve, detect the train speed that is about to the entrance curve section, and velocity information be transferred to central processing system.Central processing system calculates the size of required superelevation of outer rail value according to train running speed, and sends regulating command to the superelevation of outer rail control apparatus that is positioned on the segment of curve.The superelevation of outer rail control apparatus was finished superelevation and is regulated according to instruction before train entrance curve section.When train moved on curve, control monitor unit was monitored in real time to its running state, and will send out central processing system for information about same.Central processing system is passed judgment on the superelevation adjustment in view of the above and whether is satisfied the train operation requirement, in case of necessity, sends and revises the superelevation instruction.
Description of drawings
Fig. 1 is a scheme drawing of the present invention.
The specific embodiment
Superelevation of outer rail intelligence system each several part position and requirement be set:
1. speed detector A
At distance point of tangent to spiral (ZH) L place (straight sides), installation rate detecting device.Require this device can accurately detect the train speed of entrance curve section soon.Here L is an early warning distance, is after the adjustment of track superelevation value is finished, the assurance of train safe entrance curve section.Early warning distance L can estimate by following formula:
L＝V
max·Δt
V
Max---the maximum speed per hour of train driving, generally can be by existing train maximum speed of this circuit or planning maximum speed value.
Δ t---control apparatus is adjusted V
MaxThe time length of required superelevation of outer rail.
2. central processing system B
In the segment of curve appropriate positions near central processing system is installed.Central processing system is the embedded integrated chip with program curing in fact just.
Central processing system should be according to train speed size calculated curve superelevation of outer rail value; And send the superelevation regulating command for the superelevation of outer rail control apparatus; Train is analyzed by the speed of curve, judged the running state of train.
The computing formula of superelevation value:
Speed (Km/h) when V---train passes through curve.
R---radius of curve (m).
3. superelevation of outer rail control apparatus C
To the scope between point of spiral to tangent (HZ), outer rail is arranged to the adjustable rail structure of tread absolute altitude at point of tangent to spiral (ZH), can in time adjusts its tread absolute altitude according to the instruction of central processing system.
4. control monitor unit D
To the appropriate location between point of spiral to tangent (HZ), some control monitor units are installed at point of tangent to spiral (ZH).The actual speed of train by curve, train operation stationarity etc. are monitored in real time, and give central processing system this message feedback.
