FIELD: transport. SUBSTANCE: invention relates to railway ACS and telemetry systems and is intended for determination of train movement parameters. The method consists in fixing the moment of head end of a train entering portion of line being monitored and determination of ordinate of head end, speed of movement and acceleration. Additionally, ordinate, speed and acceleration of tail end of a train is continuously monitored. The ordinates are determined by measuring formed in the process of current flowing over rail line and train wheel pairs and characterised by τ3 value "lag" of trailing edge of exponential pulse fed to rail line at the middle of monitored portion. Exponential pulse is fed as I = f(e1) function limited by amplitude Imax and building-up time τi. Then train speed and acceleration are determined from ordinates. EFFECT: expanded operating performances. 2 dwg
The invention relates to railway automatics and telemechanics and is intended to define the parameters of movement of the train. The known method of control of a rail line, implemented in tone track circuits (SEC)at which the signal current flowing from the generator, spreads over a rail line in both directions to limit the receivers of two adjacent shopping center and nourishes them. In the SEC used amplitude-modulated signal, providing reliable protection travel receivers from the effects of harmonic and impulse noise traction power and other sources (Wewinwabe, Vasakronan, Eaacatalog and other Distillation system automation. M.: Transport, 2005, 79-92). The disadvantages of the method are the lack of information on the ordinate of the head and tail of the train, the speed of the train and its acceleration. There is a method of determining motion parameters of the train, namely, that capture the moment of the beginning of the entrance (entry) of a train in the detection zone of a fixed length, determine the speed of the train movement and change of speed (acceleration) [RF patent №2049693, IPC B61L 25/06. The method for determining motion parameters of the train. Authors: Kruchinin VP, Baranov I. bull. No. 34, 1995]. The disadvantages of this method are the lack of continuous monitoring of the ordinate of the head and tail of the train, the velocity and acceleration of the train The technical result is the extension of functionality through continuous control of the ordinate of the head and tail of the train, the speed of the train and its acceleration, as well as increasing the accuracy of determining the parameters of motion of the train (speed and acceleration) due to the definition of the ordinate by "tightening" of the trailing edge of exponential pulse. This technical result is achieved in that in the method for determining motion parameters of the train, namely, that capture the moment of the beginning of the entry of the head of a train on a controlled site, determine the ordinate of the head, speed and acceleration, in addition to continuously control the ordinate, the speed and acceleration of the tail of the train, and the ordinate is determined by "tightening" of the trailing edge of exponential pulse, and then the ordinates determine the velocity and acceleration of the train. The rail line is considered as electrically long line with distributed parameters. When joining the head of the train at the input end of the controllable site two parallel rails snap front wheel pairs of trains. In the mid-controlled area in the rail line serves exponential pulses as a function I=f(et), limited by the amplitude of the Imaxand duration of the rise front of τand. In the process PR is takane DC on a rail line and wheelset train is "tightening" of the trailing edge of the pulse, characterized by the value of τC. Continuous monitoring of the ordinate of the head and tail of the train and its speed and acceleration can improve the precision of the movement of the train and its location on the controlled area. The emergence of a "tightening" of the trailing edge and his character is explained by the influence on the passage of the exponential pulse ratio of wave propagation:
where R0, L0, G0C0active resistance [Ohm/m] inductance [GN/m] rail line, the conductivity of the leakage through the ballast [Cm/m], line capacitance [f/m], respectively, related to the unit length of the line. The main influence on the "tightness" of the trailing edge has an inductance L0under the condition of equality of the output resistance of the source exponential pulse wave resistance is considered long line. Figure 1 presents a graph of the current pulse generator output time figure 2 - graph of the current pulse at the input of the receiver from time to time, depending on the ordinate of the train. The method is implemented as follows. A train approaching the source of the exponential pulse (figure 1), reduces the inductance of a rail line between the first shunt and the source, which leads to proportional humanistically "tightening" of the trailing edge τ Cpulse (figure 2). Measuring the duration of the "tightening" of the trailing edge of the pulse determines the ordinate of the head of the train. Pulses in the rail line continuously with periodicity T and each of them is fixed ordinate the head of the train x1xi+1, xi+2,..... On the difference between the measured value of y is determined by the speed of the train:
Speed two piece rail line is determined by the acceleration:
Determination of velocity and acceleration is more accurate due to more accurate determination of the ordinates of the train by "tightening" of the trailing edge of exponential pulse. When the identity sent in the rail line exponential pulse adopted the conclusion that the inductance is equal to zero and the head of the train is on the ordinate of the source pulse. As the pulse propagates in both sides of a rail line from the power supply is turned on, the control of the ordinate of the tail of the train, and the speed of the train and the acceleration is carried out according to the above principle, in the process of removing trains from the source of pulses. The proposed method, by increasing the echnosti define the movement of the train and its location, will improve safety on the controlled area and to reduce the interval between consecutive trains. The method for determining motion parameters of the train, namely, that capture the moment of the beginning of the entry of the head of a train on a controlled site, determine the ordinate of the head, speed and acceleration, characterized in that it further continuously monitor the ordinate, the speed and acceleration of the tail of the train, and the ordinate trains determined by measuring educated in the process of current flow on a rail line and wheelset trains and characterized by the value of τC"tightening" of the trailing edge is fed into the middle of the controlled area in the rail line exponential pulse as a function I=f(et), limited by the amplitude of the Imaxand duration of the rise front of τandthen the ordinates determine the velocity and acceleration of the train.
