Description

DESCRIPTION APPROACH DETECTION AND A KIND OF WARNING FOR RAILWAY VEHICLES Technical Area Meet; the variable distance between the vehicle and the vehicles around it instantly. by detecting that a vehicle is approaching below the specified distance, which can control Approach detection for railway vehicles that warn the user visually or audibly and the warning system.

State of the Art Railway transportation is the movement of transportation vehicles called trains on two steel rails. It is the name given to the system that provides transportation opportunity. According to other modes of transportation It offers a safer and faster transportation opportunity. Because in any density It is called fast because there is no waiting situation. Security Although it is considered safer than road transportation in terms of road transport, increasing passenger and freight traffic Along with it, the need to increase the security level of transportation has emerged.

Collision avoidance systems and approach detection in sea, air and road vehicles anti-collision systems, which are also mentioned in railway vehicles, such as systems and approach detection systems are increasing day by day. Trustworthy Such practices are now becoming more important in order to ensure transportation. has started.

For this reason, today, by working on various technologies, different security systems are being developed. In these systems, ultrasonic sensors, optical sensors, laser sensors, GPS and GPRS modules, radar systems, wireless communication infrastructures etc. technologies are used.

Railways in passenger and freight transport in the world compared to other transportation methods has become more preferred and this situation is increasing day by day. Most of this easy access to the transport vehicle, end user and business In terms of low cost, on time transportation and security come.

In the state of the art; With the expansion of railway transportation, road, passenger and it has created the need for many R&D studies in terms of vehicle safety.

Especially European countries have given importance to the issue of security and this issue has ERTMS (European Railway Train Management System) has gone to standardization. This is the number of railway vehicles that will work on European railways. required to comply with the standards. An infrastructure conforming to this standard and Developing suitable systems for it is very costly.

However, with each passing day, both in Europe and in many countries of the world. railways are made suitable for the mentioned infrastructure.

If an example of the current technique is given; available in Turkey 9000km conventional railway line and 900km high-speed train railway line There is railway signaling in approximately 3000 km. with signaling 900km high-speed train line of the approximately 3000km long railway line ERTMS It is level 1. The remaining signalized railway lines signaling is at Level 0.

Starting from the example above, we started to work on the Turkish railways infrastructure. "An automatic train" with application number TR2004l02864 developed in accordance with There is the invention titled "stop system". The summary of this patent is as follows: "Invention place a locomotive magnet that switches the magnets and the ATS control Unit. It is an ATS control system, the feature of which represents the position information along the same line but ground magnets belonging to at least two different ground magnet groups with different properties contain at least two locomotive magnets that can switch and the mentioned ATS control The position of the unit along the same line from at least two of the mentioned locomotive magnets. at least two signals representing, but different, position information along a single line. characterized by its assessment as In the patent application resulting in the above document, ATS (Automatic Train This system, called the Stopping) system, has a signaling infrastructure. in railways, according to the scenarios determined by the railways automatically stop the train when necessary in case of signal violation. It is a system that provides. For this system to work properly railways must have a suitable infrastructure.

Another system related to railways is patent number TR2007I05031. Patent titled "Train Control System" registered with the application application / document. The summary of this application is as follows: “The invention especially, in the mechanic; road, traffic situation, location of locomotive and train, according to road and traffic situation exceeding the permissible speed, which gives information about the speed to be made and the actual speed automatic slowing of the train in case of emergency or other danger situations or by various sensors from the train and the locomotive, which The collected data, location and speed information can be added to the GPS system and the system. It confirms with units such as RF-lD, Doppler radar, and informs the center at the same time. record this data to the recording device included in it for later analysis. It relates to a train control system (TDS) that ensures ” The above patent application has been made for the system; road, traffic situation, The location of the locomotive and the train, the speed and speed to be made according to the road and traffic situation. which gives the actual speed information, in case the permissible speed is exceeded or in case of different dangers. from the train, which allows the train to be automatically slowed or stopped in case of and the data collected from the locomotive via various sensors, location and speed GPS system and units such as RF-LD, doppler radar that can be added to the system confirming it with the center and reporting this data to the center at the same time, a train that allows it to be recorded on the recorder for later analysis control system. The most important feature of this system is that the railways are required to work. It does not need signaling infrastructure or ERTMS system.

In the above-mentioned systems, passenger and freight trains operating on the railways It is used in towing locomotives. These systems have a front and a back. they may not know that there is another rail vehicle. signaling only a second railway vehicle to the same railway block at the same time due to its infrastructure. entry is prohibited. However, ATS / TDS systems or signaling infrastructure two railroad tracks at the same time to the same block, either in a controlled manner they are far from detecting the other railway vehicle on the line in case the vehicle enters.

This process is completely manual by the machinist/operator and road controllers. is carried out.

However, the situation mentioned above for "Railroad Road Vehicles" is slightly different.

Railway Road Vehicles; road maintenance/repair and construction works on railways together with the accident-breaking team when an accident occurred on the railways. who removes the railway vehicle from the road, then does the maintenance and repair of the road They are tools used for the purpose of putting them into use.

For this reason, even if the maintenance and repaired lines are signaled, they are on the same line. working on condition that more than one railway vehicle maintain a certain distance should be able to.

Therefore, more than one road maintenance vehicle at the same time at very close distances to each other. can take place in the same block and even should be able to.

In the current art, railway road vehicles are completely machinist/operator and road controllers. are guided manually. Entirely left to human initiative Due to this situation, sometimes major damaged collisions may occur.

In the present art, also, while the vehicles on the railway are in motion, The distance is mostly tried to be maintained by the users' own skills.

This distance is fog, torrential rain, etc. when the visibility is low, In curves where the distance is limited, at tunnel entrances and exits may decrease and reach a level that may cause collision. For these reasons Because of this, accidents with high costs are also experienced every year.

In addition, vehicle-vehicle communication (V2V) for collision avoidance in the literature Significant research has been carried out in recent years. This technology in the future vehicle collisions, side beam control, intersection crossings, etc. important contributions to is also expected.

Standards have been established with many researches on this subject, but they are not accepted commercially. products that have been seen have not yet been put on the market. For some level crossings, highway It is known in the art that different patents exist for tools. other some train-train using Ultra Wideband (UWB) and WIMAX communication. The communication system is envisaged as anti-collision. On some other systems radar, laser, camera, etc. A sensor-based collision precaution has been developed.

Computer vision technology has great potential for modeling the environment Although the weather conditions and the lighting in the environment are likely to change, It is not preferred in such vital systems as it is a problem.

Another known problem in the state of the art is the high computational cost.

With the above explanation, long range radar (Long Range radar) working with 77 GHZ Radar) and laser scaners (Laser Scanners) can measure up to 300 m computer vision, providing the same performance in most situations as its They are powerful alternative solutions against technology. Unlike radars, lasers scanners flexibility to work with the same device over short and long distances can show. With radar, the distance is dependent on the operating frequency. your radars The biggest disadvantage is that he has limited lateral vision (with an angle of 15 degrees). covers) is the problem with the measurement area. But in fog, rain and heavy snow conditions, radars do not have a detection problem. However, weather conditions laser browsers cause reflection, scattering, weakening of the signal and false echoes. can happen. Today, when we look at many wheeled vehicle manufacturers, these It puts it in its vehicles as an active safety system.

On the other hand, important research on long-range radar sensors In the 2000s, long-distance radars were used for driving support in vehicles with rubber wheels. started to be used commercially as part of the system. Railway When looking at the tools of the different researches are still continuing.

In addition, a train collision avoidance system developed for commercial purposes in the current art example is; Andreas Lehner, Fabian de Ponte Müller, Thomas Strang and Cristina Rico "Reliable Vehicle-Autarchic Collision Detection For Rail Bound" by Garcia It is an academic publication published with the title "Transportation". Here is the link for this publication It is as follows: http: l/elib.dlr.de/60056/1/ITSOQfinaIvSpdf The main purpose of this system is to next to the current position of the trains and the railway line they are on, from the train By establishing instant communication with the train, additional information such as the size and length of the trains around to publish information.

Moreover; htto://www.railiournal.com/index.phD/sicinallind/domesticallv-developed-tcas- TCAS mentioned in the shows-potentialhtml link or “Train Collision” in its open form "Collision Avoidance System For Rail Line" registered in the States The system named Vehicles is known to exist. defined in these systems. TCAS, radio communications with railway signal data, GPS and radio frequencies based on a combination of identification devices. These systems are available can be given as an example of the products produced in this field in the art.

As mentioned above, there are different communication and communication options for various platforms. positioning systems are used. Radar systems in sea and airways, railway signaling on railways, GPS and GPRS modules, wireless communication systems, radar and optical sensors in road vehicles, v2v communication etc. is used.

However, these products are only used in passenger and freight transportation. It is produced in accordance with trains / locomotives. Our invention is about railway road vehicles. and the life and death of the personnel in charge of road construction/maintenance/repair works in the railway. It is a system designed and produced to ensure the safety of goods. In this aspect, other completely separated from the systems.

In addition, we meet at the beginning of the important features that distinguish our invention from other systems. Independent of infrastructure and ERTMS and similar Signaling systems it can work. In other words, there is no need for any infrastructure for the invention to work.

When there is a signaling infrastructure, it can work in harmony with this infrastructure, but It can also perform its duty without signaling. Other systems are efficient and railway signaling infrastructure is needed for safe operation. they hear.

As a result, due to the above-mentioned negativities and existing solutions approach detection and warning for rolling stock system is necessary.

Railway road vehicles, while reaching the point where the road works are carried out or road construction They follow each other at certain distance intervals during their work. this follow up within the capabilities of the engineers and by means of radio communications. is being done. In adverse weather conditions, sharp curves, tunnels, etc. at points visibility is reduced and the distance between railway road vehicles is colliding. reaches a dangerous level. In past years this There are accidents due to reasons. As a result of the accidents railway road vehicles, railway lines and railway infrastructures are damaged.

In addition to material damage, loss of life can also be experienced. Our invention It does not need the high infrastructure costs required to operate, the locomotive tracking modules, odometers, wireless communication and radar systems. benefits. Current existing systems Safety of Railway Road Vehicles is not sufficient for Our invention differs from the current state of the art. It has been specially designed and developed for railway road vehicles.

Today, in our invention developed for railway vehicles, high level found in adaptive cruise control systems It has the same structure as the control algorithm.

In the Adaptive Cruise Control (ACC - Adaptive Cruise Control) system, the aim is to It is to perform speed control without exceeding the safety distance determined with the vehicle. ACC While the vehicle with the system is in motion, the information received from the radar sensor is processed and control is performed. If the radar cannot detect any vehicle, in this design, the vehicle performs the course at the desired speed. Radar detects any vehicle in front of the vehicle If it does, the system calculates the speed using the data from the peripherals, and The distance information is processed and the vehicle speed with the ACC system is adjusted according to the vehicle in front. the engine and brake of the railway vehicle, the commands and data necessary to adjust to their systems. High level control under the conditions found in this system It sends the acceleration information that the vehicle should apply to the low level control. received acceleration information is performed in the low-level controller.

Our invention, which we developed for the railway road maintenance vehicle, is separated from the ACC system. point is low level control. Low level control in the developed design does not exist. Acceleration, the output of the high-level control, as described above The brake information to be applied to the vehicle is converted into warning levels by taking the information of the vehicle. The brake information to be applied is visualized in the user interface interface of the mechanic.
