| As an important part of the jointless track circuit,the compensation capacitor plays an important role in ensuring the transmission quality of the jointless track circuit signal.At present,the researches,on the reliability of jointless track circuit,take the relationship among the compensation capacitors as the series model,which ignores the reliability redundancy of compensation capacitors.Aiming at this problem,this paper puts forward a method for calculating the reliability of the jointless track circuit based on the reliability redundancy of compensating capacitors.The main research work of this paper is as follows:1.Based on transmission line theory,taking the uniform as a special case of non-uniform,this paper establishes a wider track circuit signal transmission model.2.A jointless track circuit reliability calculation method based on the reliability redundancy of compensation capacitors is presented in this paper.Through the modeling and simulating the short circuit current and receiver voltage,a boolean truth table between the compensation capacitors and track circuit is built.And then,Quine-McCluskey algorithm and binary decision tree method are used to calculate the reliability of jointless track circuit.3.An effect degree calculation method of compensation capacitor on track circuit is presented in this paper.The effects of compensation capacitors in different position on system reliability are analyzed.The influence law of how the system reliability is affected by compensation capacitors is summarized.4.Optimizing the configuration of compensation capacitors based on genetic algorithm is put forward in this paper.Taking the set of compensating capacitor spacing distances as the genetic individual,the average working hours before the track median life as fitness,through the simulation of individual selection,crossover and mutation genetic evolution,the configuration of the compensation capacitor,and analyzes the optimization results is optimized in this paper. |
