Description

The device relates to railway transport, and in particular to automation and telemechanics devices, providing control and diagnostics of the state of technical equipment on sorting slides.

Known Control and Diagnostic Complex (CDC), which is a subsystem of the KGM-PC (A.N.Shabelnikov, I.G. Sapkov, Control and Diagnostic Complex of an automated sorting slide. - "Automation, Communications, Informatics", 2002, No. 4, p. 8-12). The control and diagnostic complex displays the process flow, displays the diagnostic results of floor-mounted devices connected to the KGM PC based on the logical analysis of their operation, displays the protocol of the dissolution progress of the trains and the actions of operational personnel.

The disadvantage of this KDK is the lack of control of electrical parameters in the power supply circuits, voltages and signal currents of signaling and control devices of signaling systems, which does not allow for maintenance and fixing the precautionary state of signaling devices.

The well-known ADK-signaling system complex (A.N. Belyakov, S.P. Komarov Diagnostic and monitoring system for signaling and signaling devices. - “Automation, communication, computer science”, 2003, No. 12, p. 28-30). It carries out monitoring, state analysis, pre-failure diagnostics of signaling devices, short-term archiving of information, automation of maintenance, troubleshooting of devices through decentralized remote sensing modules.

The disadvantage of ADK-signaling is that it is focused only on monitoring the signals of devices located at a considerable distance from the central communication unit and the industrial computer of the information and computer complex (IVK) using information serial communication channels of the remote signal pick-up modules (LSS) with the central unit communication (CBS). This limits the speed of the ADK-signaling system (no more than 20 times per second) and does not allow oscilloscopy of signals and the taking of exact diagrams of rapidly changing signals (up to 3125 times per second), which is necessary for the timely detection of hidden malfunctions and the precautionary diagnosis of signaling devices of stations and sorting stations hills (SG). In addition, ADK-STsB does not provide measurement of insulation resistance and identification of faulty power supply circuits. And the lack of a database server does not allow the accumulation and long-term storage of diagnostic information, which does not allow a statistical analysis of the operation of controlled devices.

The closest is the device “Control and diagnostic complex of station devices of automatic automatic centralization” (patent No. 56308, B61L 17/00), in which the electrical circuits of the monitored devices are connected by a signal cable directly to the industrial computer of the IVK, which makes it possible to record signals with high frequency, limited only by the capabilities of the ADC devices, the insulation resistance control module allows you to determine the failure of the power supply circuit, and the database server provides information on the performance of controlled devices for a long period of time (up to several years).

The disadvantage of this device is that it is designed to analyze the information collected on the basis of the events and does not include a module for detecting dangerous equipment failures in real time, and also does not have the means of prompt notification of operational personnel about detected failures, for example, a sorting operator slides, which would be able to intervene in time in the operation of the automated system and prevent emergency situations.

The essence of the utility model lies in the fact that the control and diagnostic complex of station devices for automatic automatic centralization contains modules for inputting analog and discrete signals from monitored devices, an insulation resistance control module, remote workstations and Ethernet gateway connected via a local area network, a database server , a controller for collecting information on the basis of an industrial computer and an automated workstation of an electrician on duty A module for monitoring the status and detection of equipment malfunctions is connected with the information collection controller and the automated sorting process control system and designed to collect information about malfunctions in the operation of controlled devices in real time and a collective display panel made with the possibility of visual, voice and sound alerts a malfunction of the controlled devices, and the local area network gateway and remote automated locations are connected with a corporate data network of Russian Railways, providing the display of diagnostic and statistical information on the operation of equipment in technical monitoring and top-level diagnostic systems.

The technical result is the timely diagnosis and notification of operational and dispatching personnel of the sorting hill about identified equipment failures to prevent emergency situations during the dissolution of trains and during shunting shifts.

The technical result is achieved by the fact that the proposed device incorporates a module for monitoring the status and detection of equipment malfunctions, which, during processing of messages about the state of equipment received from the information collection controller and automated sorting process control systems, detects dangerous device failures and reports them to real-time to the operational dispatch personnel of the SG in various duplicating ways: sound alarms, voice messages reporting and displaying on the hump panel for collective use, located at the control post of the SG, on the basis of which the necessary actions are taken to prevent emergency situations in accordance with the operating instructions.

Structurally, the device is made in the form of blocks located in the IVK at the EC station, a collective ledge located in the duty room on the hill in a place that is visually accessible to all hill operators, and remote AWPs, including remote administrator’s AWP, dispatcher’s AWP distances and others may be located at appropriate workplaces.

Figure 1 presents the structural diagram of the Control and diagnostic complex of station devices of automatic automatic centralization (KDK SU GAC).

The proposed device contains input modules for discrete signals 1, input modules for analog signals 2, a module for measuring insulation resistance 3, the inputs of which are connected by a signal cable 4 to controlled devices 5, and the outputs are connected to a data acquisition controller based on an industrial computer 6, the output of which is via a local area network Ethernet is connected to the database server 7, which is connected via a local area network to the automated sorting process control system 9, the automated workstation of the standby electric Chanika 8 and a local area network gateway 12 connected via a corporate data network of Russian Railways 13 to remote workstations 14 and top-level technical diagnostics and monitoring systems, a status monitoring and fault detection module 10, the input of which is connected to ACS SS 9 , the other input is connected to the output of the KSI 6 module, and the outputs are connected to the AWS SHN SG 8 and GTKP 11 located in the duty room on the hill.

The device operates as follows.

After turning on the power, the industrial computer of the information collection controller 6 loads the operating system from the flash-disk and automatically starts the technological program. After that, the complex is ready for work.

Discrete signals of controlled devices are transmitted through modules 1 to the information collection controller 6, in which the actuation is fixed and the actuators are diagnosed.

The signals of the monitored devices 5 come through a signal cable 4 to the controller of the collection of information 6.

The levels of analog signals are fed through modules 2 to the information collection controller 6, which measures voltages and currents, monitors signal values, analyzes the status of devices, fixes failures and failures, and performs precautionary diagnostics. If necessary, an electrician with AWP 8 has the ability to display waveforms of signals from several devices technologically connected with each other on the AWP screen to more accurately determine the nature of the malfunction. KDK SU GAC displays waveforms, performing 1600 measurements per second for each of the monitored channels. If necessary, visual control of very transient signals is carried out 3125 measurements per second for each of the monitored channels.

In the process of the complex’s operation, measurement, mathematical and logical processing of signals, monitoring and analysis of the state and signal levels, mapping of the status of monitored devices to the automated mechanic 8 on the automated workplace of the electromechanics, the formation of personnel alert signals when fixing the pre-failure condition and device failure are performed. The module for monitoring the status and detection of equipment malfunctions 10, processes messages on the state of equipment received from the information collection controller 6 and the automated sorting process control system 9, detects dangerous device failures and reports them in real time to the operational dispatch personnel of the sorting hill by displaying on collective hiding panel 11, located at the control post of the SG, sound alarms and voice messages, based on Otori operators take the necessary action to prevent emergency situations in accordance with the instructions for use.

The insulation resistance control module 3 provides measurement of insulation resistance and identification of faulty power supply circuits. By commands from the information collection controller 6, module 3 connects to the measuring channel of the information collection controller 6 alternately the electrical circuits of all monitored power sources. The information collection controller 6 measures the leakage current and analyzes its magnitude. In emergency cases, the information collection controller 6 fixes the circuits with faulty isolation and notifies personnel through AWP 8, AWP 14 and GTKP 11. Measurement results are displayed in AWP 8 and 14 when the corresponding program menu is called up.

The database server allows the accumulation and long-term storage of all diagnostic information, followed by viewing and analyzing the operation of all monitored devices using AW workstation.

All diagnostic information both in real time from the information collection controller 6, and over a long period of time from the database server 7 can be transferred to one or several DK SHN workstations connected to the corporate data network of Russian Railways 13 to ensure the possibility of information transfer in the automated control system of the central locking system (ACS Ш), operating at the level of the country's railways, while the LAN gateway 12 performs the functions of information protection of the local computer network of the KDK SU GAC.
