Construction and work.

The automated system of commercial inspection 3D control (ASKO 3D Control) is designed to detect commercial malfunctions in the process of train traffic that threaten the safety of traffic and the safety of transported goods by building a 3D model of the car, its intellectual processing, visual control, monitoring the compliance of the received parameters of the 3D car model with the given patterns dimensions, monitoring the compliance of the obtained parameters of the 3D car model with the given reference car models, identifying the displacements of car elements and a load, calculated relative to the level of the rail head, as well as identifying the displacement of the car elements and load calculated on the data obtained during the loading wagon and 3D models obtained during the inspection on the previous system ASKO 3D control from the trains. The system uses high-definition cameras and / or linear scanning cameras that form an image due to progressive scanning of the subject. Cameras (6 in total, but may be more) are located 2 each to the left and right of the rail track and 2 cameras are located above the rail track. For example, cameras can be installed on railway bridges, in railway tunnels, or on a supporting structure that includes two supports and a crossbar. On one of the side chambers are at a level of 0.5-1.5 m from the rail head, preferably from 0.5-1 m, it is also possible, option 0.55-0.95 m, option 0.6-0.9 m, option 0.65-0.85m from the rail head. These cameras have their own noise reduction system and ultra-high resolution (up to 16k). Data from the cameras is transmitted over the local area network to the inputs of the signal processing module. The output of this unit is connected to a network switch, from which the signal is fed to a PC. The operator in the process of passing the controlled composition receives a 3D model of the composition, where the faults are highlighted. The operator can mark a wagon with a visually noticed commercial malfunction for further processing and decision making. In video windows on AWP monitors, compensation is provided for geometric distortions of video images from linear scanning cameras. Information received by the system from its own technical subsystems of video recording and laser monitoring in real time is displayed on the operator’s monitor in the form of a multi-screen interface displaying video from television cameras, an interactive 3D model of the car and cargo with identified malfunctions for visual detection of commercial malfunctions, at the same time the operator receives the result automatic processing of information from controls in terms of detecting ha-violations by the software and hardware module cargo and rolling stock barrels, cargo displacement relative to the loading scheme, cargo displacement along the route relative to the wagon, detecting uneven loading, displacement of the center of gravity, remnants of previously transported goods, unrecorded or erroneous danger signs, mismatch of the wagon's inventory number declared in the train's full list, deviation the weight of the wagon and cargo relative to those declared in the carriage and other documents, breaks, cuts, distortions of the wagon body. Additionally, the system should provide receiving and issuing the resulting information to the operator about comparing the generated 3D model with the received models from the systems that carried out control earlier along the route of the wagon and the cargo, the predicted probability of a further change in the state of the cargo relative to the primary control result along the route. Also, the system should ensure the formation of relevant information, reports, telegrams, and the maintenance of necessary journals. Maintaining archives of video recordings and 3D models of inspected trains and wagons, creating databases of wagon and cargo conditions for the period of a single carriage and during the life cycle of a wagon. Transfer of information on the results of control to adjacent automated systems.

The system being created is both an independent system for recording information on the commercial inspection of wagons and goods, its intellectual processing and generation of reporting documents at one railway station, and a linear link in a network system consisting of several ASKO 3D Control systems on train routes, allowing analysis and intelligent processing of results obtained from similar systems throughout the train / wagon / cargo route.

ASKO 3D Control includes 6 high-resolution television cameras or linear scanning cameras (depending on the local operating conditions of the railway station) for visual monitoring of the condition of car roofs and walls, tank hatches, unloading and other devices located in the lower part of the car, 3- x or more single-beam or multi-beam laser scanners (depending on the local operating conditions of the railway station), providing control of loading dimensions and rolling stock, detecting uneven load, about statistics of previously transported goods, displacements of the cargo relative to the car and previous measurements, obtaining a measurement database for creating, visualizing and archiving a 3D model, as well as further intelligent processing, a system of strain gauge and optical sensors for counting and measuring the speed of cars in the control zone, lighting systems based on LED spotlights with a luminous flux, depending on the used high-resolution television cameras or linear scanning. Technical controls, car counts, and lighting controllers are integrated into a local network and after processing the generated signals in the processing and matching module, they transmit information to the Workstation AWP 3D Control through network switches. AWP 3D Control carries out software intellectual processing of the information received from its own technical means, compares the results of the control with the information about the controlled trains, wagons and cargo obtained from the results of previous inspections of the route and data received from adjacent systems from AWP FFP. Carries out visual display of inspection results on a monitor screen and archiving the results of monitoring of all subsystems. The resulting certificate is transmitted to the PKO automated workplace, in which additional intellectual processing of the results of the commercial inspection, the formation of accounting records, the necessary messages, reports and telegrams takes place. The inspection results are transferred to an external data network.

To accommodate the control equipment of the ASKO 3D Control, a typical supporting structure can be installed in the place where the information was taken (installed above one or several railway tracks, depending on the local conditions of the railway station and consists of metal or reinforced concrete supports on which a metal crossbar is placed).

To provide visual control of wagons and cargoes, six television cameras (TK (KLS) 1) - TK (KLS) 6) are located on the supporting structure. 2 chambers on each side located on the supports of the supporting structure and 2 chambers on the crossbar. The system uses high-definition cameras (resolution up to 4k), or linear scanning cameras that form an image due to line-by-line scanning of the subject. These cameras have their own noise reduction system and ultra-high resolution (up to 16k). Depending on the local conditions of the station, the prevalence of certain types of wagons and types of controlled cargo, the ASKO 3D Control system can be implemented in various configurations and include various layout options from standard high-resolution cameras and linear scanning cameras. Data from cameras is transmitted over the local area network to the inputs of the signal processing module (MOS). The output of this unit is connected to a network switch, from which the signal is fed to a PC ARM 3D Control.

At least 3 laser scanners, one on each support and one on the crossbar, are placed to ensure dimensional control and the formation of 3D models of controlled wagons and cargo on supports and a crossbar of a supporting structure. Depending on the local conditions of the station, the prevalence of certain types of wagons and types of controlled cargo, the ASKO 3D Control system can be implemented on single-beam scanners that scan space in a plane perpendicular to the movement of the car and measure in the polar coordinate system the distances and angles to various points of the controlled cars and cargo, or on multi-beam scanners that generate a beam of rays distributed over the surface of the control object. As a result of measurements with a multi-beam scanner, a three-dimensional cloud of points is obtained, which more accurately describe the surface of the car and cargo. Data from scanners (LAN 1, LAN 2 and LAN 3) is transmitted via a local area network to the inputs of the signal processing module (MOS). The output of this unit is connected to a network switch, from which the signal is fed to a PC ARM 3D Control.

At the installation site of television cameras and scanners (in one plane), a strain gauge wheel counting sensor (TDSK) is installed on the rail, and an optical speed measuring sensor (ODIS) is installed on the supporting structure. The signals from these sensors are transmitted through the local area network to the inputs of the signal processing module (MOS) and then through the network switch to the PC ARM 3D Control.

At the moment the train enters the working area of the system, from the first axis of the first carriage of the train, a strain gauge wheel counting sensor (TDSK) is triggered, the signal from which is fed to the input of the signal processing module (MOS), where an electrical impulse is generated about the beginning of the train, which is through a network switch (SK 1) starts recording the composition at the automated workstation AWP 3D Control. At the same time, video signals from television cameras (TK (KLS) 1) - TK (KLS) 6), scanners (LS 1, LS 2 and LS 3) and an optical speed measurement sensor (ODIS) are also transmitted via a local area network to the inputs of the signal processing module (MOS), where they are pre-processed and synchronized, then through a network switch (SC 1) they go to the automated workstation ARM 3D Control.

The controlled composition, when passing through the working area of the system, is visualized on a display tool - the AWP 3D Monitor, which displays information from the television cameras selected by the operator (TK (KLS) 1) - TK (KLS) 6) and scanners (LS 1, LS 2 and LS 3). The operator in the process of passing the controlled composition can mark the car with a commercial malfunction visually noticed on the display means for subsequent processing and decision making.

AWP 3D Control, implements visualization and processing, storage and archiving of information, using the strain gauge wheel counting sensor (TDSK) determines the beginning and end of the train, counts the cars, using the optical speed measurement sensor (ODIS) calculates the speed of the controlled train, reveals to predefined criteria for violation of the loading and rolling stock dimensions, compares the results of the control with the information about the controlled trains, wagons and goods, with the information obtained from the result Am of previous inspections of the route and data obtained from adjacent systems from the automated workplace of the FFP.

According to the results of the inspection, with the help of our own technical means of video recording and laser control, as well as processing by the operator AWP 3D Control, a certificate of detected commercial malfunctions is automatically generated. The generated certificate, through the network switch (SK 2), is automatically transmitted to the working automated workplace of the PKO. By means of AWP PKO, the formation of accounting records is carried out: certificates, reports, telegrams, and the maintenance of necessary journals.

A set of equipment for the warning subsystem is designed to remotely send warning signals to the area of the supporting structure of the system using an audible siren in order to prevent vandalism. The siren is located in the overall gate alignment.

System operation

The ASKO PV 3D Control system is based on a set of hardware and software tools for the automated workstations of a commercial inspection point, which includes AWP 3D Control with installed software and AWS PKO.

Digital signals from six cameras are transmitted via Ethernet to be displayed on the AWP 3D Control monitor screen.

When receiving information about the train’s approach to the control zone, the operator enters the number of the received train and the number of locomotives in it, as well as the order of their train from the keyboard of the AWP 3D Control PC: when following the locomotives, “0” is entered in the train tail and the number of locomotives is entered in the train head from one to four. The information entered by the operator is transmitted to the matching unit which loads the internal counter of the cars and begins the survey of laser scanners.

When the train crosses the installation site of the wheel sensor, electrical signals are generated, which are sent to the control and processing unit where the signal to start processing is generated and transmits it to the AWP 3D Control, while the process of recording information on the HDD of the AWP 3D Control system unit begins. The control and processing unit, analyzing the signals from the wheel sensor, maintains an ordinal count of passing train cars and calculates its speed.

Using optical sensors, a signal is generated about the detection of a train in the observation zone. In the case of a train stop (deceleration), the sensor continues to receive a signal about the presence of a car in the observation zone, and the process of recording information continues at a reduced speed. With the resumption of train movement, the count of cars will continue.

Laser scanners control the space in the alignment of the dimensional gates, forming a scanning plane perpendicular to the direction of train movement. As the composition passes through the scanning plane, an array of transverse profiles is formed, each of which is compared with templates for loading dimensions. The exit of the scanned profile beyond the template is fixed as oversized and displayed on the 3D model as shaded areas (red), as shown in FIG. 3.

In three video windows (or four, depending on the configuration), the video of the passing train coming from high-definition television cameras or linear scanning cameras (depending on the local operating conditions of the railway station) are displayed on the AWP 3D Control monitor screen, and the oversized zones display panel Information from laser scanners is displayed in the form of a contour of the current section of the car, on which the identified oversized items are displayed in red. Video windows provide compensation for geometric distortion of images from television cameras. The fact of oversize is accompanied by a sound signal and is recorded in the archive, located on the hard drive of the ARM 3D Control system unit with fixing the serial number of the car. If necessary, the operator can in the playback mode of information from the selected camera by pressing on the AWP 3D keyboard Control a certain key mark a frame with an image of a car with a noted malfunction.

After passing the train, the operator can view the recorded information. Playback of the image is possible with arbitrary speed in the forward and reverse directions. If a frame with a faulty car is detected, the operator switches on the STOP-FRAME mode and, if necessary, prints the generated image (hard copy) on a printer or saves data on an external medium. In the STOP-FRAME mode, the operator can scale arbitrary areas of the image. When viewing archived records, it is possible to form a three-dimensional model of the car, obtained as a result of splicing of transverse scanned car profiles.

When opening the hardware cabinet located on the supporting structure, a video clip is recorded from the camera that is programmed and in the viewing zone of which there is a cabinet. In this case, the operator is informed about this event by a sound signal and a message about opening the cabinet on the monitor screen.

Information exchange between AWP PKO and AWP 3D Control is carried out through a local area network based on a network switch. The sound signal is given by the siren in the alignment of the supporting structure of the controlled path by command of the operator. The lighting in the gate range can be switched on automatically or manually.

The lighting is automatically switched on in two versions: using a digital astronomical timer or upon arrival of a train in the dark. With the help of a digital astronomical timer, the illumination turns on with the onset of dark time of the day and turns off with the onset of daylight. If the inclusion of lighting upon arrival of a train is programmed, then it will turn on only in the dark and when the locomotive stops the alignment of the supporting structure, and the illumination turns off after the last train carriage. In the dark, when the train is in the range of the supporting structure or when the digital astronomical timer has worked, the operator does not have the option of forcibly turning off the lighting.

To exclude fogging of the optical windows of the containers of the cameras, the appearance of condensation in the equipment cabinet, as well as lowering the temperature in them below the permissible temperature, heating is turned on / off when the temperature inside / out of their enclosures is reduced using temperature sensors.

Information exchange between AWP 3D Control and AWP PKO is carried out via a local area network. In ARM 3D Control, AWS PKO sends messages about the train arrived, received from the full-scale sheet (serial and inventory numbers of cars). In ARM PKO from ARM 3D Control, messages are sent about the inspection of the arrived train and commercial defects found.

In case of coincidence of the data of the received message displayed in the windows indicating the serial and inventory numbers, and the video data of the AWP 3D Control software analyzed by the operator by means of visual control, the data received by technical means are transmitted through the local network to the AWP FEC, where reporting and accounting are generated documentation.

In case of mismatch between the inventory numbers received from the message and the inventory numbers of the wagons displayed in the video windows of the AWP 3D Control monitor and visually evaluated by the operator in the AWP 3D Control database, the corresponding wagons are marked by the operator for quick access to the image of a specific wagon and manual adjustment of the wagon's inventory number .

When the operator has access to marked wagons to manually adjust the wagon's inventory number, the validity of the entered information is checked.

AWP PKO provides automatic reception of data from AWP 3D Control, and on the basis of these data the operator generates an updated full-scale sheet (regarding the correspondence of the number of wagons and inventory numbers in the train) and transfers it to the station's data transmission network.

The use of the ASKO 3D Control system for the automatic detection of commercial railroad car malfunctions in trains improves safety on the railroads by increasing the level of fault monitoring and controlling the oversize of railroad cars or goods, which improves the quality of inspection and improves the predictability of train safety violations as well as create safe working conditions and improve the safety of workers.
