The well-known "Microprocessor-based centralization and automatic locking system for railway transport" (utility model patent No. 107753, B61L 27/04, B61L 19/04 priority 23.03.2011, publ. 27.08.2011). It contains a central processor, including microprocessors, communication devices with an object (USO), including interface modules for collecting information (MCI) on the status of objects of control of a railway station and adjacent hauls, interface modules for transmitting critical commands (IOC), which are connected to actuators for electrical centralization and auto-blocking (EC and AB), characterized in that the central processor contains three microprocessors that are inter-channel interconnected and each of them is connected to two microprocessors, while on the one hand the automated workstation of the station duty officer (AWP DSP) is connected to the processor, and on the other, three-channel USO devices connected to the executive devices of the electronic and battery modules via a relay-contact interface (RCI) containing relay of monitoring objects and control relays, while the three-channel USO devices contain peripheral microprocessors (interconnected inter-channelly - each microprocessor is connected to two neighboring ones), MCI modules connected to normally closed and by RCM contacts, RCI and IOC modules, and the power input of the IOC module of each drip is connected to the power output of the controlled power source (IP) of its channel, and the control outputs of the IOC module are connected to the inputs of its own and neighboring channels, the input of switching on the IP is connected to the " Launch ".

However, this system:

- has a relatively low level of fault tolerance due to the fact that when a single USO system fails, the system does not fulfill all the functions assigned to it (OOF does not have the possibility of redundancy, but it has a sufficiently large redundancy);

- it has the practical complexity of monitoring and managing facilities at large stations due to the fact that with a large number of facilities the number of simultaneously executed interdependencies and communication messages becomes such that it is almost impossible to implement them using processor and trunk means for an acceptable system response time that is acceptable for electrical centralization;

- has decentralized means of recording and archiving personnel actions and system reactions to the workstations themselves, which means that, with certain malfunctions of individual workstations, access violations or erroneous actions of the staff and system will be hidden or unnoticed when viewing archive data from other workstations;

- has a limited structure of information interaction with UVK, that is, it does not provide for the placement of additional workstations, remote workstations, the division of stations into control zones, the enlargement of stations into dispatch control areas, the differentiation of rights to manage individual sections or objects, therefore, there is insufficient configuration flexibility to requirements customer;

- has a redundant construction structure for industrial vehicles, therefore, has insufficient configuration flexibility to customer requirements.

Also known is the "Microprocessor centralization system with route dependencies MPC-M3-F" (patent for utility model RU

No. 79083, B61L 25/04, priority August 22, 2008, published December 20, 2008).

The microprocessor centralization system is characterized by the fact that the control computing computer is based on a control computer that provides the main functions of centralization for the control and management of arrows, traffic lights and other objects of railway automation and telemechanics in compliance with the safety requirements for train traffic in accordance with the principles adopted in existing EC devices . The microprocessor centralization system is characterized in that the SIMIS-ECC is the base control computer. The microprocessor centralization system is characterized in that the control computing computer consists of three identical processor devices and has a structure of two out of three. The microprocessor centralization system is characterized by the fact that its work is carried out in real time.

This system:

- also has a relatively low level of fault tolerance due to the fact that when a single USO device fails, the system does not fulfill all the functions assigned to it (OOF does not have the possibility of redundancy, but it has a sufficiently large redundancy);

- has decentralized means of recording and archiving personnel actions and system reactions to the workstations themselves, which means that, with certain malfunctions of individual workstations, access violations or erroneous actions of the staff and system will be hidden or unnoticed when viewing archive data from other workstations;

- has a limited structure of information interaction between AWP and UVK, that is, it does not provide for the placement of additional AWPs, remote AWPs, dividing stations into control zones, enlarging stations into dispatch control areas, therefore, has insufficient configuration flexibility to customer requirements;

- has a redundant construction structure for industrial vehicles, therefore, has insufficient configuration flexibility to customer requirements.

The closest in technical essence and the achieved effect to the claimed utility model is “Microprocessor centralization of the arrows and signals of the MPTC” (patent for invention RU No. 102579, B61L 25/04, priority 05/14/2010, published 03/10/2011), selected for the prototype, and which is an object-oriented programmable device with a variable composition of functional blocks necessary to create the required configurations of input-output channels, specific functions and tasks of railway automation and telemechanics with the aim of organizing and the transportation process, characterized in that its hardware is implemented in the form of a three-level hierarchical structure: information support, logical support and direct control, while the first level of information support contains an automated workstation for the station duty officer, which provides the status of monitoring and control objects, as well as the formation of tasks for the control of arrows, closure and opening of routes, the third level contains a relay contact nye devices that provide instruction execution control computer system for the direct management of outdoor equipment and monitoring its condition, wherein the control computer system is based on SIMATIC programmable logic controller with variable composition of functions that implement algorithms for functions and railway automation and remote control tasks. Microprocessor centralization of arrows and signals may contain equipment and software that allows it to be coordinated with any type of switch electric drives and traffic lights. Microprocessor centralization of arrows and signals can allow integrating any axis counting systems, moving tunnel and other alarms, voice warning systems, hitchhikers, control and dimensional devices, interval control systems, supervisory control systems. Microprocessor centralization of arrows and signals implements the functions of service and self-diagnosis

However, this system:

- has a relatively low level of safety due to the fact that the SIMATIC family of programmable logic controllers used in the system in a single-channel version do not provide the SIL3 safety level in railway systems according to the international standard EN 50126, which is insufficient for microprocessor-based centralization systems for industrial railway transport and to the need for redundancy and redundancy of equipment.

- has decentralized means of recording and archiving personnel actions and system reactions to the workstations themselves, which means that with certain malfunctions of individual workstations, access violations or erroneous actions of the staff and system will be hidden or not noticed when viewing these archives from other workstations;

- has a limited structure of information interaction between AWP and UVK, that is, it does not provide for the placement of additional AWPs, remote AWPs, dividing stations into control zones, enlarging stations into dispatch control areas, therefore, has insufficient configuration flexibility to customer requirements.

The task to which the claimed utility model is directed is to provide flexibility and efficiency in using the microprocessor-based centralization system for arrows and signals by increasing the completeness of self-testing of equipment and ensuring a variety of methods for its application depending on customer requirements.

Solving this problem, microprocessor centralization of arrows and signals was created, which controls and monitors the status of outdoor devices (electric drives, traffic lights, crossings, rolling stock status monitoring, etc.), integrates the main types of automatic and semi-automatic blocking, dispatch centralization, diagnoses elements microprocessor devices, measures and diagnoses the basic parameters of guard and floor devices.

The technical result obtained by using the utility model is to provide the required level of safety and reliability when creating various systems of microprocessor centralization of arrows and signals with an optimal ratio of reliability and cost indicators, that is, to provide flexibility and efficient use of the system. The proposed model of a safe reconfigurable microprocessor centralization system provides control and management - objects of electric centralization (EC) and automatic blocking (AB) at all types of stations from small to large, with any type of traction with adjacent stages and is designed for all categories of customers involved in rail transportation , both for industrial enterprises, and for the main railway transport).

The indicated technical results are achieved in that the microprocessor centralization of the arrows and signals is a three-level hierarchical system with a variable composition of functional blocks for solving problems of railway automation and telemechanics, where the upper level includes at least one automated workstation of the station duty officer and / or dispatcher, if necessary, workstations of an electrician, telecommunication cabinet ШТК, medium level, includes at least one in the control centralization controller UCC, including at least one centralization controller KC, safe interface devices USO, the lower level includes, if necessary, a backup control panel, interface relay circuits, outdoor equipment, power supply system, characterized in that in order to ensure the flexibility and efficiency of the system, the centralization controller of the control center is designed with an increased depth of testing and self-testing of hardware and software, has self-locking devices when the improvement of dangerous situations and provides the solution of functional tasks in real time with a minimum cycle of operation for any system configuration, which allows the system to perform the basic functions in real time with a level of safety in a single-channel operation mode acceptable for use in non-general-purpose railway transport systems ,, and the control centralization controller of the UCC allows you to provide a level of security through reconfiguration of the structure single-channel d, two-channel and two-channel with a backup kit for use on all types of stations with adjacent stages.

The increased depth of testing and self-testing of the hardware and software facilities of the control center is selected based on the analysis of single and multiple failures of all controller nodes during all types of operations and is achieved using well-known methods:

- isolation of computing devices of all nodes and modules from each other to minimize the degree of influence of potential failures for common reasons through the use of independent power sources and specialized hardware and software;

- self-testing of computing devices of all nodes and modules with the goal of identifying all types of potential failures through the use of specialized hardware and software tools that carry out self-tests of all operations for the interaction of these computing devices, including the operations of wrapping and converting information, coding and acknowledging operations, generation and control test messages and signals, feedback control from control circuits, dynamic conversion of passive bus bits, etc .;

- comprehensive fault tolerance used for self-testing of specific nodes, such as, for example, non-volatile real-time readout devices made on fundamentally different hardware technologies and software algorithms;

- reactive fault tolerance used to introduce protective states of all modules in diagnosing potentially dangerous failures.

- own fault tolerance used in terminal units and self-blocking devices based on USO, responsible for safety and maintaining a protective state, up to and including irreversible de-energization of control channels or computing channels as a whole without human intervention.

- combining the above methods, if necessary. The UCC centralization control controller consists of one KC centralization controller and has a single-channel structure, or the UCC centralization control controller consists of two identical KC centralization controllers and has a two of two structure with cross-comparison of information between the KC after its input, processing and before its output, as well as with hardware comparison of discrete control outputs with the help of safe devices for interfacing with UOF objects, or control centralization controllers of the UCC can have a reserve and exactly the same UCC, forming a single-channel structure with a reserve, or a duplicated structure with a reserve, for servicing large stations can 1, are connected to a logical cascade of five UCC organized by the control program of the first UCC, while the centralization controllers of the CC of a single-channel structure can be grouped in pairs for placement in the same closet of the UKC.

The essence of the utility model is illustrated by drawings. Figure 1 presents the structural diagram of the MPC-I:

- 1.1.1-1.1.n - the automated workplace of the station duty officer or dispatcher (AWP DSP);

- 1.2.k - automated workplace of the electrician of the signaling system (AWS SHN);

- 2 - telecommunication cabinet (ШТК);

- 3 - centralization control controller (UCC);

- 3.1.1-3.1.m - centralization controller (CC);

- 3.2 - safe interface devices (USO);

- 4 - interface relay circuits;

- 5 - outdoor equipment;

- 6 - backup control panel (Remote control board RU);

- 7 - guaranteed power supply system (SGP)

Figure 2 presents the functional diagram of the microprocessor centralization of arrows and signals. Figure 3-5 presents a functional diagram of various options for using the system.

The system provides for the use of standard outdoor equipment (rail chain equipment, axle counters, traffic lights, electric drives, shunting columns, control panels for technical inspection points, etc.), which are serialized by industrial plants as centralization objects.

To organize the interaction of the system’s components with each other and with external systems, physically separated local area networks (LANs) are organized, the central link of which is the ShTK telecommunication cabinet.

Microprocessor centralization of arrows and signals provides the implementation of the whole range of tasks of electrical centralization of arrows and traffic lights for the organization of operational work of the station. The solution of the complex of tasks is performed continuously and cyclically in the UKTs and ShTK, continuously and sporadically (as the operators influence) in the AWP DSP and AWP SH. The reaction time of the system to any external (from the upper level) impact is 1-2 seconds. The reaction time of the system to any impact from the objects of control (lower level) is 0.1-0.2 seconds.

Microprocessor centralization of arrows and signals is a complex of programs and devices that are composable (designed) into a single system when equipping each particular station and providing installation, closure, opening of routes at the station and the fulfillment of the required interdependencies to ensure the safe movement of trains.

For the normal functioning of the system, power supply devices with control of feeder switching and built-in uninterruptible power supply (UPS) are required to protect against failures and loss of information when exposed to interference from the power supply, as well as when switching power feeders and emergency power outages.

Floor objects are controlled through safe USOs, which are part of the control centralization controller of the UKZ, using interface relays. Direct control of objects and control of their condition is carried out by interface relay circuits, or other elements with similar characteristics.

The hardware and software implementation of microprocessor centralization of arrows and signals provides for the possibility of information linking with other railway automation and telemechanics systems - ZhAT (dispatch centralization - DC, dispatch control - DC, automated process control systems - ACS TP, automated transportation management systems - ACS OP ) At the same time, information for other systems is concentrated by the upper level of microprocessor centralization of arrows and signals, and communication is carried out through the STC using communication modules, in accordance with the general standards and recommendations of the relevant organizations as part of technical solutions for linking with these systems.

For information transfer, modern digital information transfer means integrated into the STC are used with the RS-232C, RS-422, RS-485, Ethernet 10Base-T / 100Base-TX (IEEE 802.3) interfaces, which have the ability to work with physical cable and overhead circuits, and also with digital channels of fiber optic lines. The information transfer rate is determined by the organization method and type of communication channel.

To create combined posts, remote workplaces, dispatch areas, etc. the local area network of the LAN is used, organized by means of the ShTK and, if necessary, channel-forming equipment. LAN provides guaranteed delivery of transmitted information to the right place and for a given time. Local area networks of the LAN use noise-protected coding and special procedures to protect information during transmission. To limit access to the system in the STC, gateways and LAN partitioning as intended are used.

Hardware architecture

Microprocessor centralization of arrows and signals, as a complex of hardware and software (see Fig. 3-basic version of the system), is built according to a multi-level scheme:

Upper level

It includes:

- automated workplaces of the duty officer at the AWP DSP station;

- an automated workplace of an electrician of the signaling and signaling system of the automated workplace SHN;

- telecommunication cabinet ШТК, concentrating in itself:

- redundant top-level software operation control servers, as well as data logging and backup;

- Means of a redundant local area network of information transfer between the components of the system;

- means of organizing and backing up the transfer of information between the system and other levels of the automated dispatch control system for train traffic and monitoring the health of technical equipment (SDUM);

- means of exchanging information between the system equipment and the upper control levels (information gateways and filters), limiting unauthorized access to the system.

- network printing devices;

- cable and optical LAN networks.

Intermediate level (implementation level of logical dependencies)

This includes the control centralization controller of the UKZ with system-wide and technological application software for this station, which implements the functions of the central dependencies and locks of the electric drives in accordance with the requirements for automation equipment and telemechanics on the railway transport.

The UCC includes:

- two centralization controllers (CC), forming two computing channels, with installed functional modules in them:

- module of the central processor of the MPP;

- digital input modules MF-01;

- output modules relay MF-02;

- digital output modules MF-03;

- input modules analog (combined) MF-14;

- MPI serial interface module;

- power supply stabilized BPS;

- connection modules of the corresponding types (MP MCP, MP-3, MP MPI, MP BPS)

- blocks of BUSO interface devices with modules of devices for interface with USO-BR-03 devices installed in them;

- a control cabinet (ШУ КЦ) with communication and electrical equipment (terminal blocks, automatic machines, etc.), as well as a construct for mounting, protection and grounding of the above devices.

The system design is made in accordance with the Euromehannka standard (IEC 60297-3-101). This standard is the most widely used for industrial automation systems. When designing systems in accordance with this standard, the maximum number of modules (slots) installed in one rack (frame of the centralization controller of the CC) is 21. Accordingly, taking into account the service modules constantly installed in the controller, the maximum number of general-purpose input / output modules installed per highway, does not exceed 17.

The system provides control and management of a large number of objects in comparison with the prototype. So one centralization control controller, made according to the two-channel scheme, provides the connection capacity of up to 544 I / O channels, which corresponds to the capacity of the I / O channels required to control the station up to approximately 30-35 centralized switches. One centralization control controller, made according to a single-channel scheme or according to a single-channel scheme with 100% redundancy, provides the I / O channel connection capacity required to control the station about twice as much.

Lower level:

It includes:

- direct control remote control, installed if necessary, to implement the "Standby control" mode in case of failures of the automated workplace of the chipboard or the centralization control controller;

- interface relay circuits and other fast equipment of automation and telemechanics;

- input-communication equipment for connecting equipment to communication lines, signaling cables and power sources;

- guaranteed power supply system.

Software architecture

In the software for microprocessor centralization of arrows and signals, two levels can be distinguished.

Computing complex VK (upper level)

It is a set of software systems and components used to organize human-machine, machine-machine interfaces and build distributed control and monitoring systems of any complexity.

For the normal operation of all components of the system, the multifunctional redundant local computer network of the system is organized by the hardware and software of the telecommunication cabinet ШТК. Different LAN levels perform physical separation of functionally different groups of devices from each other (UKZ from AWP and external systems, and vice versa). Interaction of all types of groups among themselves is carried out only by means of gateways and specialized components of the computing complex, regulated by the project and with strictly specified protocols.

All operations performed by users of automated workstations or external systems are pre-tested in the subsystem of identification and authentication of VC users for legality of the rights to manage and control this user with this object.

All commands specified by users of automated workstations, or by external systems, come through the STC to the control program, which decides on the possibility of their execution. In the opposite direction, to the upper level, information on the status of floor objects and routes (indication) is cyclically received, which is concentrated in the STC and distributed to all clients when it is changed.

In addition, the VK additionally provides for the recording and archiving of information about events related to the movement of trains and shunting, recording the actions of the station duty officer.

Management program (intermediate level)

The control program is designed to ensure the implementation of the whole range of tasks of electrical centralization of arrows and traffic lights for organizing the operational operation of the station:

- Installation of elementary, composite and variant routes for train and shunting movements;

- automatic opening of sections of routes with logical control of the train following the route with protection against short-term loss of the shunt ability of rail chains;

- cancellation of unused routes with a choice of time delay depending on the type of route and the state of the approaching area;

- artificial opening of sections of routes;

- selection of a signal indication of a traffic light that encloses a route depending on the established route and indications of a forward traffic light;

- management of traffic lights;

- turn off the permissive indication of traffic lights without canceling routes;

- setting routes without opening traffic lights;

- installation of routes without opening traffic lights with the removal of part of the security conditions (with masking the false occupancy of the rail chain);

- coding of routes and pick-up routes at the station;

- opening of the unused part of the shunting routes during corner races;

- filing notices for crossings within the station and in areas approaching the station;

- the implementation of an individual time delay for the opening of each traffic light that encloses the crossing;

- individual translation of arrows;

- individual closure of the arrows;

- individual translation of arrows in auxiliary mode;

- automatic return of witters arrows in a protective position;

- automatic transfer of arrows to the guard position when setting a guarded route;

- automatic shutdown of switch motors during long-term work on friction;

- single or double attempts to translate the navigation arrows when setting the route;

- turn off the arrows and isolated sections from centralization while maintaining the use of signals;

- fencing of the receiving and departure tracks;

- transfer of individual station switches to local government;

- management of warning systems;

- management of arrow cleaning devices.

The control program is performed with continuous verification of the correct functioning of all the hardware and software tools involved in these processes.

Reserved UKZ

The redundant UCC (see Fig. 4) is used to increase the reliability (availability coefficient) of microprocessor centralization of arrows and signals.

When using a redundant UCC, a backup control panel is not provided.

To build a redundant UCC, a structural type of redundancy was used, in which an additional element, a redundant UCC set, was introduced into the system structure. The method of structural redundancy is applied - a single general reservation with 100% replacement of the control computer complex. The reserve set of UCC is normally in a ready, but unloaded reserve, while the parallel development of control decisions is not made.

Thus, the redundant UCC consists of two elements: the main set of the UCC and the reserve set of the UCC. The division into the main and reserve sets of UKZ in the system is conditional.

The main and reserve sets of the UCC are completely similar to the UCC, made according to the same design and project documentation, and having the same version of the system and adaptation software.

In relation to the control objects, as well as to the formation of the indication and perception of the commands of the computer complex, each of the UCC sets can be in one of three interaction modes: active, passive, or off.

The main UCC in the system is the kit that is currently operating in active mode, the backup UCC is the kit that is currently operating in passive mode.

The transfer of each set of UCC from passive mode to active and vice versa is carried out by the control program using the hardware (relay) circuit for switching sets of UCC. Scheme (fixes its position, excludes arbitrary deactivation of sets or switching between sets for any single faults within a given circuit. The active or passive interaction mode of a set of UCC is determined by the position of the devices of the set switching circuit.

Controls the switching between sets of UKC station duty officer (DSP). The need to switch to a backup set of UCC is determined by indicating the status of the main UCC on the monitors AWP chipboard.

Cascaded UKZ

The cascaded UCC (see Fig. 5) is used for equipment with microprocessor-based centralization of the switches and signals of large stations, when the capacities of the input / output subsystem of the base UCC are insufficient and the zonal principle of division of the station is not suitable for its operation technology.

When using a cascaded UCC, the system can function in standard operating modes provided by applicable technical solutions for a base or redundant UCC. For the base control center, this is “Main Management” or “Standby Management” (if, according to the project, there is a standby control panel); for redundant UCC - only “Main Management”.

To build a cascaded UCC, a method of expanding the input / output subsystem due to similar control computing systems was used, in which the logical structure of the "middle" level of the system is divided into elements - the central UCC and the cascaded UCC.

The central and cascaded UCC are similar to the UCC, made according to the same design documentation, and having the same version of the system and adaptation software. The UCC are distinguished by external connections and their own parts of the adaptation software of the station in accordance with the design data.

The technological logic of the station is concentrated only in the central UCC, the cascaded UCC do not perform technological operations, but operate under the control of identical hardware and software security systems of the UCC. Cascaded UCCs cyclically transfer all technological information from their own I / O subsystems, as well as information about the health of hardware and software to the central UCC, where management decisions are made based on complete information. The decisions of the central UCC together with the signs of the current operating modes are also cyclically sent back to convert the solutions by the output subsystems of the corresponding UCC into physical effects on the interface relays. Information is sent directly, each operating cycle of the control program using specialized built-in serial interfaces MPI.

In the case of the redundant version of the UCC, two identical cascades from the UCC are used. Inside each of the cascades, the controllers interact as described earlier, and between the cascades the controllers do not make any interactions (i.e., are autonomous), except for the interactions necessary to determine the activation modes between the central UCC according to the corresponding technical solutions for redundancy.

In microprocessor centralization of switches and signals for large stations, controllers are separately combined into logical cascades with odd (KTs1, KTs3, ...) and even (KTs2, KTs4, ...) numbers of all UKTs. The centralization controllers are combined using serial interfaces of MPI connected to parallel buses from shielded pair twisted cables or fiber optic cables (depending on the applied versions of MPI).

The maximum number of cascaded UCCs is determined by the permissible time for updating information within the operating cycle of the control program, the allowed time for the exchange of information, the amount of information transmitted and the time of interaction with each of the cascaded controllers. The maximum number of cascaded UCCs, according to calculations and tests, can be no more than four UCCs (not counting the central one).

Thus, the maximum capacity of the cascaded I / O subsystem I / O subsystem can be no more than 2720 discrete I / O channels, which in average system design indicators covers a station with a configuration of approximately 150 centralized switches.

This means that a cascaded system of microprocessor centralization of arrows and signals provides control and management of a multiple number of objects compared to the prototype and thereby achieves the specified technical indicators.

UKC for industrial enterprises

Microprocessor centralization of arrows and signals for an industrial station (see Fig. 6) may contain a variable number of centralization controllers CC (but not less than one), which is determined by the project depending on the required number of input / output channels and redundancy requirements of the controllers. Centralization controllers installed to increase the capacity of input / output channels are logically combined in cascades in accordance with the relevant technical requirements (principles) of the base system, but are grouped two in each of the UCC. Centralization controllers installed for backup purposes are logically paired.

The first UCC for each station is equipped with the MPTs-I Server and a set of network equipment for organizing a LAN.

AWP DSP is installed with the number of monitors defined by the project in the following possible options:

- redundant option "with a table" (default);

- non-reserved option “with a table” (upon special request);

- not supplied (for zones with remote control and no need for temporary local control).

AWP SHN is installed with the number of monitors defined by the project in the following possible options:

- household option "no table" (default);

- portable version (upon special request);

- industrial version “with a table” (upon special request);

- not supplied (for zones with remote control and no need for local maintenance).

Thus, a useful model - microprocessor-based centralization of arrows and signals integrated by MPC-I - allows you to provide the required level of safety and reliability when creating any required systems for monitoring and controlling the movement of trains with the optimal ratio of reliability and cost indicators for monitoring and controlling EC and AB objects for use at all types of stations (from small to large, with any type of traction) with adjacent stages for all categories of customers involved in rail transportation to for industrial enterprises, and for the main railway transport).
