Description

Technical field to which the utility model belongs

The invention relates to automation and telemechanics devices on railway transport, systems for organizing and controlling the movement of trains at railway stations, to recovery systems for operational (short-term) restoration of interrupted traffic when committing terrorist acts, enemy exposure, earthquakes, explosions, fires, floods, and other cataclysms ( emergency situations - emergency).

State of the art

Currently, for the rapid deployment of operational control of electrical interlocking devices (EC) of a station in cases of damage to posts and EC devices in the event of an emergency, mobile EC complexes are used in transportable modules:

Known mobile complex "Inventory control post MK ETs-IN" [1, 2], which is a universal mobile autonomous complex post EC based on modules "North". It consists of a station attendant module (DSP), a relay module and a diesel generator module (DGA). The module also includes two relay cabinets (SHRU-M).

The EC-9 was chosen as the EC with the use of the modernized BMRTs-BN blocks. Basic MK ETs-IN allows maximum control of twelve turnouts on four receiving-departure tracks. This mobile complex can be adapted in a short time (no more than 8 hours) without modification for the track development of any station with operating floor EC equipment and ferrying devices for organizing the movement of trains.

The chipboard module contains: a workstation with a control panel, technological and operational communication devices, a resting place, a refrigerator, a dry closet, a battery cabinet, power racks (supply panels), a switchboard and a cabinet for intermodular connections.

The advantages of the MK ETs-IN inventory control station are:

1. EC used in MK EC-IN is widespread on the road network, simple and reliable in operation;

2. Deployment of the complex takes no more than 8 hours;

The disadvantages are:

1. The operation of the complex is possible only with the operability of the existing floor-standing devices for regulating the movement of trains and the cable network, however, in the event of an emergency there is a high probability of their destruction, and the lack of forces and means for their restoration will not allow them to return to a working state;

2. The lack of systems for diagnosing the technical condition of devices will not allow monitoring the safety of train traffic;

3. BMRTs-BN is very cumbersome and this requires a large space of premises for the placement of relay interlocking equipment.

Known mobile complex EC-MPK-M [3]. It is a complex of microprocessor-based equipment that ensures the performance of the functions of an automated workstation for EAF (AWP EAF), EC and interfacing with floor objects (arrows, signals, devices for monitoring the vacancy of rail sections, etc.), interval control systems, crossing automation, as well as teleinformation exchange with higher-level systems. The mobile station ETs-MPK-M, mounted in block-containers, consists of a hardware module, a technological module and a module of an autonomous diesel power plant. Due to the implementation of a number of functions by means of computer technology, a reduction in the area of service and technical premises is achieved in comparison with a relay-type EC.

The EC-MPK-M system consists of the following functional subsystems: control and monitoring of signaling, centralization and blocking (SCB) means, which should ensure the performance of traditional EC functions; interactive, which ensures the interaction of the operating personnel of the EC with all subsystems; regulatory reference, which must contain all the necessary data for the effective operation of the system; diagnostics of the technical condition of devices; logging, which should provide a "black box" function; auxiliary, including devices for ensuring the operation of the station.

ETs-MPK-M is built according to a three-level structure, where the upper level of the devices represents the EAF workstation, which also implements the functions of the electromechanical workstation. The second level includes a set of technical means of command and control. The third level includes the executive circuits of relay interlocking, while the performance of functions ensuring traffic safety is assigned to the minimum number of relays of the I class of reliability.

The advantages of EC-MPK-M are:

1. Technological control system with functional subsystems including control of signaling devices;

2. More compact equipment, takes up less space.

The disadvantages are the lack of forces and means to restore the floor-standing devices for regulating the movement of trains and the cable network, since the operation of the complex is possible only with the operability of the existing floor-standing devices for controlling the movement of trains and the cable network, and in the event of an emergency there is a high probability of their destruction.

Also known is the invention "Mobile complex of a microprocessor control system for arrows and traffic lights of a railway section" (MK MPTs) [4]. The invention relates to a mobile complex of a microprocessor-based automated control system for railway switches and traffic lights and can be used to quickly restore train traffic on railway sections in conditions of damage to a centralization post or during restoration work [5]. The specified technical result is achieved due to the fact that the MC MPC includes: two interconnected control computers for centralization, installed on the serviced section of the railway, one database server connected with control computers for centralization, and a second automated workstation for centralization; a set of equipment for indicating the state of the equipment of the section and controlling the section of the railway with arrows and traffic lights; a power supply device associated with control computers and configured to communicate with turnout drives, traffic lights and a contact interface relay.

The advantage is the ability to use a contactless interface to control train control devices, however, only for a limited number of devices.

The disadvantages include the operation of the complex only when the operating floor devices for regulating the movement of trains and the cable network are operable, and the lack of forces and means to restore these devices.

The closest technical solution to the claimed invention can be attributed to the Modular workshop for an electromechanical signaling system (MPM-SHM) [6, 7], intended for use as a mobile modular building for maintenance and repair of signaling devices. MPM-SHM, consisting of a workshop, a storeroom and a vestibule, provides safe and comfortable working conditions for workers in the automation and telemechanics farm in any area. By installing the module in close proximity to the work site, operating costs are reduced.

The module is equipped with the following systems: lighting, heating, supply and exhaust ventilation, security and fire alarm systems, power supply of the module from a single-phase 220 V mains with a frequency of 50 Hz. To increase vandal resistance, the cable entry is made from the bottom. The frame is welded from bent metal profiles, the entrance door is metal, insulated, with a reinforced lock.

However, with the prompt (short-term) restoration of train traffic control, it has a number of significant disadvantages:

1. There is no equipment for the implementation of a mobile EC post;

2. Restoration of floor devices is possible with the supply of materials, structures and equipment, i.e. in the presence of emergency recovery means or the use of devices from low-activity lines;

3. This workshop module allows only minor repairs and there are no technical means for the production of destroyed items at the work site.

The common disadvantage of the above complexes is:

1. Use of cable networks. If the stations are destroyed, they will most likely be destroyed, and the installation of temporary lines will take time and resources;

2. Small coverage of outdoor devices control;

3. Limited use of outdoor devices.

Disclosure of invention

The objective of the claimed invention of a modular recovery point for signaling, centralization and blocking (MVP-SZB) is to increase the efficiency of repair and restoration work to restore the regulation of train traffic at the railway station, including floor-standing signaling devices and their control over the radio channel during periods when from - due to external influences, cable networks are destroyed or rendered inoperable.

The result of the use of MVP-SZB is the possibility of a phased increase in the throughput and processing capacity of the railway station. Initially, the opening of the through movement of trains at the railway station is ensured with the possibility of further restoration of floor-standing devices for regulating the movement of trains and their control.

Under MVP-SCB we mean a complex of technical devices, including:

post MVP-STsB with a storage area and a set of mobile additive manufacturing (Fig. 1, pos. 9-12, 17), equipment for connecting to the EC post and power supply unit (Fig. 1, pos. 1), control and transmission equipment (Fig. 1 pos. 8), communication modules (Fig. 2 pos. 21 and 22), an automated workstation (Fig. 1 pos. 7), memory unit (Fig. 2 pos. 26), a system of technical diagnostics and monitoring (Fig. 2 pos. 25);

stand-by power source autonomous DGA with an uninterruptible power supply unit (Fig. 2, pos. 14 and 15);

an executive module (IM) (Fig. 1, pos. 13);

station floor restoration kit (Fig. 1, pos. 27-31).

The technical result is achieved by connecting the MVP-STsB with a cable set (Fig. 1, pos. 1) to the existing EC post or to the above recovery complexes of the EC mobile posts [1-5], the presence of an autonomous backup power supply (Fig. 1, pos. 14-15 ), equipment for interfacing the EC post devices with the station floor equipment via a radio channel (Fig. 2), a system for technical diagnostics and monitoring of signaling devices (Fig. 2, pos. 25), a station floor restoration kit (Fig. 1, pos. 27-31 ), located in the storage area, as well as the use of a set of mobile additive manufacturing, with the help of which it is possible to repair existing floor equipment and create a new one to replace the broken one. In essence, MVP-STsB does not replace the above systems for restoring the regulation of train traffic, but supplements them.

MVP-STsB is placed in a container body of variable volume (Fig. 1). This ensures the possibility of transporting it by all types of transport, rapid deployment on the ground, comfortable working conditions for personnel.

The main power supply of the MVP-STSB post is carried out from the power supply installation of the EC post, backup from the DGA (Fig. 1, pos. 15) and an uninterruptible power supply, the floor devices are powered by the DGA (Fig. 2, pos. 14).

When exposed to emergency situations, the EC of the station may be exposed to dangerous effects and become inoperative. With a large scale of destruction, and especially destruction of the cable network, a decision can be made to deploy the MVP-signaling system. Since the cable network is not functioning, the commands transmitted by the EAF go through a temporarily laid cable from the EC post to the input-distribution cabinet (Fig. 1, pos. 2) of the MVP-STsB post and then through the control and transmission equipment (AUiP) through closed radio channel to floor-standing devices using a remote antenna (Fig. 1, pos. 32). If a digital signal is supplied, then it is transmitted to AUiP without conversion (Fig. 1, pos. 8), if the signal is analog, there is an analog-to-digital conversion of signals in the interface cabinet (Fig. 1, pos. 3). After that, the data is transferred to the AUiP, which:

configures the parameters of message transmission using built-in algorithms, depending on the signal quality;

coordinates the interaction of the elements of the recovery point;

provides reception / transmission of data from the MVP-STsB post to / from the executive (s) modules (s).

The workstation has a service PC (Fig. 1, pos. 7) with a built-in automated information system to support decision-making when restoring signaling devices after an emergency. With the help of the AWP, the operator has the ability to monitor the operation of the entire MVP-STSB, make settings, establish connections for new devices or perform the necessary calculations. The automated information system for decision support during the restoration of signaling devices includes programs for personal computers, databases [8-11].

AUiP (Fig. 1, pos. 8) is a rack on which a processor unit (Fig. 2, pos. 23), a memory unit (Fig. 2, pos. 26), a technical diagnostics system unit (Fig. 2, pos. 25) and a communication module (Fig. 2, pos. 22). The operation of the processor module (Fig. 2, pos. 23) is carried out using three processors according to the principle of security "2 out of 3", in which the operation of the computer is carried out when at least 2 two processors are in good working order. Otherwise, AUiP ceases to carry out its work and go into a safe state.

The memory unit (Fig. 2, item 26) is responsible for storing information about the transmitted messages, the applied transmission parameters and the algorithms of the communication module (Fig. 2, item 22). Consists of two components - operational (RAM) and read-only (ROM) storage devices. The ROM, being a non-volatile part, is responsible for storing data processing algorithms, settings for the elements of the transmission / reception circuit, transmitted messages, and operation logs of the MVP-STSB. The information storage period is configured separately depending on the operating conditions. RAM stores data required for the current operation of the module.

The use of the system of technical diagnostics and monitoring in centralization allows implementing additional functions. Namely:

automatic logging of the operation of the system and devices, operator commands;

provision of regulatory information and technical characteristics of the railway station;

measuring the voltage of power feeders at the railway station;

measurement of switch current, parameters of track circuits;

storage, viewing, statistical processing of failures in the EC system;

analysis of the parameters of the EC system to identify pre-failure conditions.

Information is displayed on the operator's workstation upon request; it is also possible to select separate information zones of the operator's workstation for specific data, for example, displaying the switch current.

The implementation of the extended functionality is based on the use of specialized software that serves to record the operation of devices, interface with information systems and process other incoming information.

The exchange of information between elements is based on standard protocols used in computing systems and local networks.

Data storage is organized as follows: the state of the train situation, a text protocol of the monitoring results and EAF actions are archived during the operation of the system. This data is not available for correction and is stored for one month; if necessary, the information can be transferred to an external medium.

A distinctive feature of the described solution is the possibility of its implementation both as part of the EC equipment and as a separate physical module. This allows, if necessary, to expand the functionality of the module by replacing it with new versions, both in software and hardware upgrades.

The communication module (MC) MVP-STsB (Fig. 2, pos. 21 and 22) is responsible for the formation of the communication channel from the reverse side. Setting up MS MVP-SZB for functioning in the required quality can be done in advance or directly at the work site using a PC. To prevent the influence of third parties on the work of the MVP-signaling system, the transmitted data is encrypted.

Executive modules (IM) (Fig. 1, pos. 13) are designed to receive commands from AUiP (Fig. 2, pos. 8) through the radio path and transmit control actions to control objects, as well as to transmit diagnostic information from control objects to the post MVP-STsB (Fig. 2). IM are installed near outdoor devices (equipment). A cable is used to connect to outdoor devices. The location is chosen in such a way as to cover as much equipment as possible and to minimize the use of cable. IM power supply (Fig. 1, pos. 13) is produced from the power supply of floor devices or an additional DGA (Fig. 1, pos. 14) installed directly at the module. The total number of IMs (Fig. 1, pos. 13) required for the organization of communication within the railway station depends on the structure of the construction and the number of control objects.

The IM includes:

1. Communication module of the executive module (MC IM) (Fig. 2, pos. 21);

2. Controller (Fig. 2, pos. 20);

3. Connection board (Fig. 2, pos. 19);

4. DGA (if necessary) (Fig. 1, pos. 14).

The work of the MS IM (Fig. 2, pos. 21) is cyclical. In each loop, it produces:

transfer of diagnostic information to AUiP;

checking the connection between the central post and control objects;

testing of internal resources of radio transmitters (mutual data exchange between them).

When transmitting orders, the control messages are generated by AUiP and transmitted to the MSP-STSB (Fig. 1, pos. 22), which processes the transmitted signal for transmission to the IM (Fig. 1, pos. 13). MS MI (Fig. 2, pos. 21), having received the signal, processes it to eliminate interference and transmits the message to the MI controller (Fig. 2, pos. 20), where it is decrypted (processed).

When transmitting diagnostic information from the MI (Fig. 1, pos. 13) to the AUiP (Fig. 1, pos. 8), the message is generated by the MI controller (Fig. 1, pos. 20) and transmitted to the MS (Fig. 2, pos. 21) for processing and subsequent dispatch to AUiP MVP-STsB (Fig. 1, pos. 8).

A storage area has been organized to accommodate ready-made station floor recovery kits at the MVP-STsB post. In which is located:

1. Switch electric drives (Fig. 1, pos. 27);

2. Axle counters (Fig. 1, pos. 28);

3. Mast traffic lights (Fig. 1, pos. 29);

4. Dwarf traffic lights (Fig. 1, pos. 30);

5. Relay cabinets (Fig. 1, pos. 31).

When restoring a station, to quickly organize the regulation of train traffic, it is advisable to use the existing station floor restoration kit and the surviving floor devices (equipment), as well as the equipment that needs minor repairs, since dismantling the old one and installing the new one will take more time and resources. Therefore, MVP-SCB is equipped with a set of mobile additive manufacturing, which includes an AWP (Fig. 1, pos. 7), a 3D scanner (Fig. 1, pos. 5), a 3D printer (Fig. 1, pos. 10, Fig. 1, pos. 11), a place for the final processing of products (workbench and racks with tools) (Fig. 1, pos. 9, Fig. 1, pos. 12). The order of work is as follows:

the damaged device is inspected, the amount of work and the necessary elements are determined;

in the database of 3D models, a search is made for the necessary devices and their parts, and if they are not in the database, a 3D scan of the object is performed, a 3D model is created and sent to print;

product processing (grinding, removal of auxiliary elements, etc.);

mounting on a recoverable device.

A significant difference is the use of these devices and equipment in a single complex. In the patent and technical literature, such a set of technical solutions has not been found.

Thus, the declared mobile recovery point for signaling, centralization and blocking ensures prompt short-term restoration of train traffic at the destroyed railway station for the period of restoration of floor signaling devices and cable network. This is achieved by the absence of a large volume of earthworks, the rejection of the use of cable networks, the use of additive technologies for the rapid restoration of floor devices using a radio communication system, which increases the efficiency of organizing the regulation of train traffic at the railway station.
