A formal model of a human metrologist is given. The optimal duration of inter-verifi cation period and average number of object’s repairs for one year are determined. With the help of real model, the average age of human-operator, in terms of maximum availability coeffi cient, with and without prophylactic periods is determined. In the formal and real models of man-operator the distribution of human life time is determined by the extreme in statistics Weibull distribution law. From the formal point of view “chaos environment” is characterized by a probability distribution function, opposite to the distribution function of “concentration environment” by P. Levy. A quantitative relationship between the stages is defi ned and a formal way of realizing this relationship is proposed.

The structure of train traffic control processes is presented with the example of the State Unitary Enterprise “Moscow Metro” and the main tasks that need to be solved to achieve high levels of automation of train traffic control in subways are described. A functional structure of a complex of metro train traffic control systems is presented, covering the levels of organization and planning of train traffic, operational traffic control and direct executive systems. The relationship between objects of automation and remote control of train movement, devices of the operational level and systems of organization and planning of movement are shown. The necessity of re-equipping the metro with means of ensuring transport safety and linking them with traffic control systems such as: means of informing passengers, providing the possibility of promptly informing passengers both during normal operation of the transport system and in case of emergency situations, means of communication “passenger – control center (situation center)” is shown. The latter ensures interaction between passengers and operational personnel of the subway, and if necessary, video surveillance equipment that provides enhanced remote control of the current situation in the interior of rolling stock cars and on platforms. The use of complex systems for controlling the movement of trains in subways increases the efficiency of their use by increasing the throughput and carrying capacity, accurate fulfillment of the traffic schedule and the possibility of its rapid recovery in case of failures. At the same time, traffic safety increases by reducing the likelihood of dangerous train convergence , and also the energy consumption for train traction is reduced due to the choice of energy-optimal train control modes and the optimal distribution of travel time along the line by the criterion of minimum energy consumption for the duration of travel along the tracks","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"270 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134236182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vulnerability of modern microproces- sor control systems and ensuring the safety of train traffic to electromagnetic impulses of deliberate influence is shown. The features of safety-critical microprocessor systems of railway automatics are highlighted, which determine the difference between the problem of ensuring the stability of these systems from the same problem with respect to information systems. Electrostatic discharge has the widest frequency spectrum. They act on the same apertures in the housings of technical means of microprocessor systems of railway automation, as the impulses of delib- erate action. When an electromagnetic wave of an intentional impulse is incident, the aperture releases this impulse and transmits it to the inside of the case. Therefore, an intentional impulse emitted into the housing and an electrostatic discharge impulse can be compared in shape and amplitude using the spectral-energy equivalence condition. The calculation of the energy and the active frequency band of the pulses most often used as deliberate pulses is considered. It is demonstrated that the calculation of the active frequency band in engineering practice is carried out by constructing an integral curve of the energy distribution in the spectrum. A technique has been developed for the indirect assessment of the impact of an electromagnetic pulse of deliberate action according to the calculated prediction of resistance to electrostatic discharges. An analogue of the equation of power suppression of radio-electronic means is demonstrated in the article allowing finding the parameters of an electromagnetic pulses generator which creates pulses dangerous for microprocessor systems of railway automation. An expression is also given for the intensity of interference, which characterizes the contribution of deliberate electromagnetic pulses to the electromagnetic environment at the location of the microprocessor equipment of railway au- tomation.","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123569049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If we consider a section of a railway as a complex dynamic system, then with a relatively small weight of fixed assets of technical means intended for interval regulation of train traffic, failures in them signifi- cantly affect the system output. On the railways of Russia, the systems of interval regulation are mainly used with the use of track circuits and the division of hauls into block. Such systems are widely used on the world’s railways. There- fore, the problem of quantifying losses in train movement from failures of electric interlocking devices while through-working and from failures of automatic blocking devices is relevant. The amount of loss depends on the intensity of failures of technical means and the time to restore their operability, on the intensity of train traffic, the length of block sections, the ratio of freight and pas- senger trains on the section, the speed of their movement according to the schedule and the degree of speed reduction due to failures of the considered technical means Both freight and passenger trains move along sections of the Russian railways, the speeds of which can differ significantly, which also significantly affects the traffic loss from such failures. When calculating, one has to use data on block crossing capacity and the capability of accelerating trains. The calculation results provide the possibility of an objective choice of the type of systems under consideration and the requirements for them in a new design or during their reconstruction on railway sections, as well as the possibility of correct distribution of costs to increase the reliability of the oper- ated systems.","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131934980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work of the support service for users of the automated control system of transport enterprises is presented as a queuing system. The possibility of using various methods to solve the problem is analyzed. A description of the work of the support service, methods of forming its departments are given. The incidents she deals with are classified. An algorithm for the formation of support service departments has been developed. It is proposed to solve this problem using a genetic algorithm. The algorithm and the concepts that characterize it are adapted to achieve the goal stated in the article. Crossover variants are presented that can be used by the genetic algorithm to solve various classes of problems. With the help of the developed software, modeling of the organization of the work of the support service was carried out using the algorithm for the distribution of employees. A comparative analysis of the results of modeling the work of departments with various methods of their formation, including those obtained using a genetic algorithm, has been carried out. The analysis showed the effectiveness of the use of the genetic algorithm when planning the work of the relevant departments. The possibility of adapting the developed algorithm for planning the work of personnel involved in the technical maintenance of the infrastructure of urban rail transport systems has been demonstrated.
