Description

The invention relates to railway transport, and in particular to systems of automation and telemechanics, electrical centralization systems, specifically to microcontroller and microprocessor control equipment sets on passenger cars of locomotive traction and can be used to automatically control the equipment of such a car to improve traffic safety and to increase the comfort of stay passengers in the car and when boarding.

"There is a known method of automatic control of wagon equipment during the route (the controller of the automatic control and diagnostics system of the KU SAUD" Express "for the electrical equipment of passenger cars E-12AK. Operation manual E-12.12.07.33.000-00RE), which makes the wagon being a part of a running train from the departure station to the destination station, the closest to the claimed one is the control method, which is used by modern sets of electrical equipment (Control Controller automatic control and diagnostic systems of KU SAUD "Express" for the electric equipment of passenger cars E-12AK. Operation manual E-12.12.07.33.000-00RE) built on microprocessor and microcontroller units (E-12 AK SPC "Express", EPV- 110 ZAO ElSiEl, EV44 LLC LATVO, EVA PO LLC Krosna Elektra, EVP-110 LLC Promtekhmontazh). The automatic way to control the equipment of the car during the route (flight) describes the algorithms for the operation of the equipment aimed at maintaining comfortable conditions for passengers riding without tracking changes in external parameters of the car guide and manual (optional) on or off the equipment.

However, in addition to the time en route (flight), the life cycle of a car is described by several other modes - time when boarding passengers at the initial station, time when disembarking passengers at the final station, time of interruption in the train between two flights, time of long sediment on the tracks. In these modes of the car’s life cycle, it is impossible to use the automatic control method along the route (flight) due to the use of other management priorities and goals in the method. So, when disembarking passengers, the minimum conditions for acceptable climatic parameters, the maximum illumination of passenger compartments and the minimum power consumption for all equipment should be provided. If the train is shut down with the priority of power conservation, sufficient lighting and operation of the water supply system must be provided for cleaning and technical work on preparing the car for the flight. If the train is stopped in the presence of a power source, the maximum permissible way of controlling the air conditioning system with the temperature output to the required value, etc. must be provided. However, in addition to priorities, the conductors of passenger cars according to the instructions must monitor the external climatic parameters to prevent freezing of equipment located outside the car or in unheated vestibules, for the presence of resources, the absence of which can lead to damage or malfunction of the equipment. As a result, in modern sets of electrical equipment in these modes, manual control is used with tracking of all climatic and resource parameters by the wagon conductor.

The technical result consists in creating a method for automatically controlling the equipment of a passenger car at all stages of its life cycle with expanding the functionality of a set of electrical equipment for a passenger car and using the nominal mode of operation of the equipment throughout the life cycle, and not only during the automatic mode of operation during a train.

The technical result is achieved by the fact that the proposed method for automatically controlling the carriage equipment is based on dividing the carriage life cycle (for which there is guaranteed voltage on the carriage) into several modes for which clear priorities can be identified: flight (travel time), landing at the initial station , disembarkation at the terminal station, interruption in train composition between flights, prolonged sludge on tracks. For each of these stages, an algorithm is described for the functioning of the car’s equipment, depending on its priorities, as well as an algorithm for connecting and disconnecting equipment to ensure the necessary sanitary and epidemiological indicators and algorithms for maintaining the working condition of the equipment.

The automatic way to control the car’s equipment over the life cycle compared to the control method used along the route will reduce the time spent by the conductor to maintain the nominal operating conditions of the equipment for each of the modes, reduce the complexity of work and increase the average life of the equipment in view of supporting the nominal modes of its operation .

The technical result of the application of an automatic way to control the equipment of a car at all stages of its life cycle is to expand the functionality of the set of electrical equipment for a passenger car and use the nominal mode of operation of the equipment throughout the life cycle, and not only during the automatic mode of operation during the train.

The invention is as follows.

The method of automatic control over the life cycle is based on switching between life cycle modes at the command of the explorer. It is understood that a specific automatic control mode can be set for each subsystem of the car individually (water supply system, toilet system, lighting and life support systems, heating and air conditioning systems, etc.), or for all subsystems of the car. In Fig. 1, the conductor for Subsystem 1 selected mode A, Subsystem 2 - mode B, Subsystem 3 - mode A. For the task of a single mode, the concept of general mode is introduced to all subsystems of the car. In the task of the general mode of the car, each of the subsystems is transferred to this mode of the life cycle. In Fig. 2, the conductor set the general mode to A, Subsystem 1, Subsystem 2, ... Subsystem N switched automatically to mode A. In addition to the life cycle modes, the manual mode also stands out for “point”, specific switching consumers on and off in case of a malfunction parts of the equipment of the subsystem or lack of resources, in view of which automatic operation cannot be carried out. When equating the general mode or the mode of any subsystem, the manual mode is allowed to turn on and off each wagon consumer individually, regardless of the equipment operation parameters and life cycle priorities.

The proposed automatic control method is implemented in the form of software for microcontroller and microprocessor units, which make up the car’s electrical equipment.
