Fiber Bragg Grating (FBG) Sensors for Railways

Fiber optic solutions for monitoring systems in the railway industryFiber Bragg grating sensors characteristicsFiber Bragg grating sensors in field projects

Fiber Bragg grating (FBG) sensors have already been applied in various applications and still arouse great production interest. They are commonly used in structural health monitoring for aerospace, civil engineering, oil & gas, etc.

As for the railway industry, fiber optic technology has made a substantial contribution to its development. It is anticipated that within a few years the number of goods that will be transported by railways will be increased, as well as the number of passengers. This, in turn, will lead to the growth of the axle load and trains' faster speeds operating.

That's why there is a great need for a full understanding of the rails' structural and operating conditions as well as for providing safe and reliable operating conditions. So modern innovative technologies are required. Fiber optic solutions for monitoring systems in the railway industry

In railways, common monitoring systems use strain gauge sensors. The sensors constantly measure resistance caused by the stress transmitted by the rail when the train runs through it. This fiber optic technology is already prominent due to its effectiveness. However, it still has several shortcomings. For example, it is expensive, huge and has difficulties in usage, in comparison with modern FBG sensors. Moreover, the most important disadvantage is that they can be affected by electromagnetic interference. FBG sensors are immune to the external interference such as electromagnetic interference, lightning and many other external disturbances.

Because of this, fiber Bragg grating sensors are getting more and more applications in high-speed railway networks. Applications are train weight estimation, measurement of train speed for real time, wheel imbalance detection, etc. It is clear from experiments that FBG sensors are more appropriate as railway monitoring systems compared to electrical ones. Fiber Bragg grating sensors characteristics

FBG sensors provide many crucial features for unique operational conditions in railways. In comparison with usual electrical sensors, fiber Bragg grating sensors have EMI/RFI immunity, multiplexing capability and can offer interrogation for long distances. In FBGs the data is wavelength-encoded, which makes the signals less susceptible to intensity fluctuations. Moreover, the fiber optic cable can be interrogated from either end, offering redundancy to FBG sensing networks. Plus, FBGs have a self-calibration capability. The strain and temperature measured findings is an absolute parameter. So there is no dependency on the measurement value and losses between the interrogation unit and the FBGs. To fabricate FBG sensors, FBGs are packaged and transformed into different types of transducers. That makes it possible to install them on the rail track fasteners, clips, bogie, train body, chassis, and axle boxes of a train to provide ongoing inspection for health checking.

In addition to that, FBG sensors can be interrogated at very high-speeds.

Providing reliable operational conditions, fiber optic designs can measure a wide range of other parameters such as inclination and acceleration through the modulation of light in reaction to the environment. Therefore, one FBG interrogator can work with a lot of FBG sensors to measure many options at the same time at different locations over the vast territory. The sensing signals can be read at distances more than 100 km away.

These features are especially useful for the railway industry because they allow simplifying the installations a lot and reducing costs. Fiber Bragg grating sensors in field projects

Over the past few years, specialists have safely held a number of field trial railway projects involving FBG sensors. For example, in 2007, about fifty FBG-based vibration sensors were installed along the East Rail Link that connects Hong Kong and Mainland China. Then fiber optic solutions were applied in metro lines of Hong Kong, part of the Beijing-Shanghai High-speed Rail Link, and in Delhi Airport Metro Express Line.

In Hong Kong this fiber optic technology was applied on a passenger rail system as a structural health monitoring system. The FBG sensors were attached to the bottom of the carriages. The goal was temperature and strain measurement. The fiber optic system supplied all the necessary data including rail tracks' and carriages' deformation. The acquired information helped to assess the rates of the corrosion and bearing wear.

According to the results, due to FBG sensors, costs of maintenance were greatly reduced. Moreover, it helped to avoid or prevent problems at early stages due to the early detection of excessive vibrations. All these works showed that FBG sensors are superior in comparison with conventional sensors in many essential aspects.

Nowadays, fiber optic solutions are regarded as one the most cost-effective technology that helps in monitoring the condition and structural health of the carriages, tracks, and under frame equipment in railway systems. There are still some parameters that need to be improved, like the lack of proprietary and custom specifications. However, in the future major railway operators can apply modern FBG sensors, gaining more field experience.

Get Information About Optic Circulators

Fiber Circulator is used to minimize the dispersion of light within a fiber optic system. Fiber optic circulators, when used with a dispersion compensating module (DCM), may send light across the system while using half the fiber to produce the necessary compensatory effect.

Applications

Optical circulators enable bidirectional ports, allowing an optical signal to be transmitted and received using a single fiber. Fiber optic circulators are utilized in a variety of applications, including dense wavelength division multiplexing (DWDM) networks, polarization mode dispersion, chromatic dispersion correction, optical add-drop modules, optical amplifiers, and fiber optic sensors.

Division Multiplexing (DWDM) Networks

Fibre Circulators in DWDM networks provide 50 dB isolation between forward and backward propagating signals.  Fiber optic circulators also have a cross-talk level of greater than 60 decibels.

Optical Add-drop Multiplexing (OADM)

Optical add-drop modules function as main filters. Optical couplers can produce this behavior by utilizing a Fiber Bragg Grating (FBG). The full bandwidth signal enters the coupler and is routed to the next port, where the FBG is inserted. The FBG reflects the required signal to the coupler, while the dropped channels depart via the port. PMD may be corrected using optical couplers, which rotate the optical signal's electric and magnetic fields.

Polarization mode dispersion (PMD)

Some fiber optic systems exhibit polarization mode dispersion (PMD), which is a natural feature of all optical media.  PMD is created by a discrepancy in light propagation velocities between the transmission medium's orthogonal main polarization states.  If the optical pulse contains both polarisation components, the individual polarisation components in fibre optic circulators will travel at different speeds and arrive at various times, causing the received optical signal to be distorted.

PMD may be corrected using optical couplers, which rotate the optical signal's electric and magnetic fields.

Chromatographic Dispersion Compensation

Optical Circulator uses a chipped Fiber Bragg Grating to adjust for chromatic dispersion. FBGs are wavelength-dependent reflectors. A portion of optical fiber is treated or doped with a substance that affects the fiber's refractive index, resulting in wavelength-dependent reflections. Chipped Fiber Bragg Gratings have numerous gratings displaced across fiber and can compensate for chromatic dispersion.

Discussion of Fiber Bragg Grating Technology Applicability on Diagnostic Field Testing of Steel Girder Bridges

Abstract

The application of Fiber Bragg Grating (FBG) technology for purposes of diagnostic field testing on steel girder bridges is discussed in this paper based on the authors experience in field tests of highway bridges. The primary benefit of the FBG technology is the ability to have many sensors (strain gages) multiplexed in a single fiber optic line. In practice, the FBG system is problematic for field conditions of a typical highway bridge. In field tests, measured FBG data showed that the strain histories obtained for a load immediately above the girder of interest were accurate, but the accuracy of the strain histories decreases for adjacent girders as the transverse distance from the load increased. Moreover, protective measures are necessary for FBG systems to be utilized in highway bridge field testing.

Textile Technological Advances

Textile improvements have been achieved in a variety of disciplines. Synthetic fabrics, sensors and actuators, spinning jennies, digital printing, and changing the essence of clothes are among them.

Synthetic textiles are garments produced from synthetic fibers. They are utilized in a variety of applications, including clothes, footwear, home furnishings, and medical devices.

Synthetic textiles are a less expensive alternative to natural fibers. They also dry faster and are more resistant to perspiration. Furthermore, they are stain and wrinkle-resistant. They also retain their form better after repeated washing.

Chemical methods are used to create synthetic fibers. Their outstanding features are one of the primary reasons for their widespread usage in a variety of sectors. Polypropylene (PP), polyurethane, nylon, and polyamides are the most common synthetic fibers.

Because of its high thermal resistance and inexpensive cost, polypropylene is commonly employed in automotive applications. Polyester is yet another common synthetic material. It's found in carpets, upholstery textiles, and side panels.

James Hargreaves designed the spinning jenny machine in 1764. It was a precursor to the power loom. This device enabled the spinning of numerous threads at the same time, resulting in increased thread output and, consequently, textiles.

The spinning jenny was one of the most important inventions in the textile industry during the Industrial Revolution. It aided in increasing productivity in the textile industry, which aided in the sector's expansion.

The spinning jenny was a device invented in the 17th century for spinning numerous threads at the same time. However, James Hargreaves patented the apparatus in the mid-1760s.

Nonetheless, it was a significant advance over previous technologies and a giant stride forward in textile production. The jenny was a primary, low-cost, hand-operated device.

Textile digital printing innovations are reshaping the garment business. With a slew of new technologies on the horizon, the industry is expected to expand significantly in the following years.

In addition to lowering production costs and downtime, digital printing has various advantages over traditional methods. For example, technology is environmentally beneficial. It also provides color and design versatility.

Smaller fashion houses are also using technology to manufacture their own items. Some businesses have even created their own "micro-factories" to produce printed textiles. This allows them to provide on-demand clothing creation, decreasing the environmental effect of transportation.

Another benefit of the new technology is the ability to print on different textiles. Traditional techniques need unique inks and treatments for each cloth type.

Sensors and actuators of various sorts are increasingly being integrated into textiles. Physical and chemical inputs are collected and converted into electrical signals by these devices. Sensors can also be used to capture and monitor health information. Traditional textile production methods may be used to create electronic textiles. These technologies' benefits include lightweight, breathability, and washability.

Small photodetectors are used in optical textile sensors to monitor the amplitude of light. They can also sense changes in temperature. The diameters of small glass optical fibers are in the micron range. The first fiber Bragg grating (FBG) sensors were created in 1978.

Resistive pressure sensors, on the other hand, link electric resistance and pressure. Wires, flexible transistors, and metals are among the architectures accessible. Textile capacitors can be constructed from conductive plates separated by dielectrics. They can be made by sewing, weaving, or painting using conductive inks.

The fashion business has experienced tremendous growth in the number of clothes manufactured each year during the last 15 years. This clothing is becoming increasingly popular across the world.

Clothing is an essential component of our culture in both established and emerging nations. It is utilized to provide comfort and security, as well as to shape our identities. However, the sector faces substantial social and environmental issues and must adapt in order to reach its full potential.

The fashion business is dependent on nonrenewable resources such as petroleum-based polyester, cotton, and nylon. Using these materials can result in massive amounts of waste and greenhouse gas emissions. Furthermore, chemicals and dangerous substances are frequently used in the clothes manufacturing process.

The UNEP has published a roadmap for a more sustainable fashion industry. It addresses the need for a new textile economy based on circularity principles, as well as recommendations for decreasing consumer impacts and making the entire textile value chain more sustainable.

#BINARY EDITOR INNOVATE WIDEBAND FREE#

Many methods have been proposed to improve the coupling efficiency of the grating coupler, and blazed grating coupler is widely studied. In recent years, SOI fiber-to-chip grating couplers have been widely reported. The coupling efficiency of a conventional fiber-to-chip grating coupler, however, is at a maximum of 40% to 60% for a standard SOI with an incident angle of 0°.

#BINARY EDITOR INNOVATE WIDEBAND FREE#

Grating couplers are widely used to couple light between nanophotonic waveguides and free space optical components. The proposed AWG demodulation integration microsystem. In this work, the InP-based C-band LED and SOI waveguide are bonded by benzocyclobutene (BCB) using heterogeneous integration. Light source is very important for the integrated microsystem, and silicon-on-insulator- (SOI-) LEDs are difficult to achieve under the current process. The proposed AWG demodulation integrated microsystem is shown in Figure 1. The current work aims to study the integration of AWG demodulation system to achieve an AWG demodulation integrated microsystem.

Fiber Optic Sensing for the Steam Assisted Gravity Drainage

Fiber optic sensing technology has proved to be an effective method in well and reservoir management. Fiber optic sensors constantly track temperature changes along the wells at specified intervals and collect all the data.

This technique is also compliant with the other technologies such as Steam Assisted Gravity Drainage (SAGD).

What is Steam Assisted Gravity Drainage?

Steam Assisted Gravity Drainage (or SAGD) is an enhanced oil recovery drilling technique that helps in extracting heavy crude oil or bitumen from oil sands deposits. Mostly, the accustomed approaches in such cases are economically inefficient. Specialists may use it in particular cases when the production is difficult. With the help of the fiber optic technology this approach becomes more cost-effective.

How does Steam Assisted Gravity Drainage work?

In short, the SAGD system's principle is heating the heavy oil or bitumen by the steam for further extraction. For that two horizontal wells are drilled at an angle of 90 degrees to a vertical bore well. In the wells, there are two pipes, one above the other for around 4-5 meters.

At the very beginning, the cold heavy oil is essentially immobile because of the high viscosity, and it needs to be warmed up to extract it. To do so, the steam is applied. It travels through the upper well into the reservoir and expends the heat in all directions of the formation, making a steam chamber. The heat warms the bitumen and reduces its viscosity. Then the bitumen flows downward into the production well and is pumped to the surface. Both processes are going at the same time.

Current Applications of the Steam Assisted Gravity Drainage

Due to the growing level of oil consumption, the level of its development needs to be increased. Not the last role is played by the SAGD and fiber optic systems such as fiber optic sensors and fiber Bragg gratings.

Like any exploration, heavy oil production needs accurate analysis and planning, especially if there are other factors that make the production difficult. Such  aspects as great depth, high temperature conditions, etc. are essential. All of these issues need to be considered. The low mobility and high viscosity make the oil producing complicated and lead to low recovery indexes. However, due to the SAGD and fiber optic technology, there is an opportunity to maximize the recovery indexes.

For SAGD technology, FBG sensors are usually applied in wells to track the steam as it moves along the wellbore. Due to the fiber optic sensors, there is an opportunity to see the data in real time. According to the achieved data, the velocity of the steam can be identified. Besides, temperature sensors can also define the speed of the heating. The accurate settings of the temperature, pressure and steam-injection rates can lead to the operational savings. All the information can be used to plan the further work of the production operations.

Fiber Optic Sensors in Downhole Monitoring

Fiber optic sensors have proved to be effective for various parameters' monitoring in downhole applications. Most of all, distributed temperature sensing (DTS) is applied for these purposes. Distributed sensing has demonstrated good results. It has high recommendations in the oil industry. DTS can monitor well temperature all over the fiber optic cable.

Due to the modernly developed fiber optic designs and improvement of fiber optic sensing technology, a range of issues related to downhole production have been solved. However, the harsh environmental conditions in the downhole can still bring some problems to the fiber optic sensors.

The sensors still need to cope with hydrogen in the severe environmental conditions. It has a great impact on the optical fibers. Firstly, it can cause pressure and temperature errors. The appearing errors are connected to the hydrogen diffusion into the microstructure and to the changes of the refractive index when hydrogen penetrates into micro holes and fiberglass. So the hydrogen leads to the additional Bragg wavelength shift.

With this in mind, specialists are constantly developing fiber optic monitoring systems based on fiber Bragg grating technology.

Advantages and disadvantages of the SAGD

SAGD has played a crucial role in the rapid development of the oil resources. However, as everything, this method has some pros and cons that should be taken into account.

Most Common Disadvantages for SAGD technology

Firstly, as any other technology, SAGD has its restrictions. It is not well-suited for every production area with heavy oil. It has several aspects to be fulfilled, like homogeneous and relatively thick reservoirs.

Secondly, high water and fuel consumption. To work effectively, SAGD needs a large amount of water and natural gas. Both of them are used in the process of steam production. That's why the energy consumption is high but worth it. When all these conditions are satisfied, SAGD technology can be used. Moreover, the specialists advise using deep water sources that are not appropriate for consumption or agricultural uses. In fact, the majority of deployments’ developers follow this recommendation for environmental protection.

Thirdly, some think that SAGD technology is an expensive tool for oil production. However, specialists consider this technology as a superior alternative to reduce the high expenses and at the same time increase productivity. The reason for the cost reduction is that less horizontal wells are required to be drilled.

Fourthly, concerns about an environmental effect of the steam assisted gravity drainage (SAGD) are still a topic of discussion. However, according to the statistics, over the last 20 years the environmental analysis is getting better. It is obvious that the production of the crude bitumen and oil cause environmental consequences, but due to the development of modern cleaner extraction technologies, the situation is improving.

The Main Advantages of the SAGD technology

The main benefit of the whole SAGD technology is the improved steam-oil ratio and high ultimate recovery. Besides, the DTS systems help in optimization of the oil and bitumen production.

The other SAGD advantage is the constant evolution. Every next project makes a great contribution and brings new ideas and experiences. Meanwhile, the diversity of newly developed methods leads to new approaches to different types of oil fields.

So there are other modified types of SAGD technique:

Shaft and Tunnel Access (SATAC);

Single Well SAGD (SW-SAGD);

Multi-drain SAGD;

Fast-SAGD;

Enhanced Steam Assisted Gravity Drainage (ESAGD).

The SAGD was firstly implemented in Canada, where there are the largest reservoirs of crude bitumen. This allowed to advance the recovery factors in excess of 50%.

SAGD (steam assisted gravity drainage) well temperature monitoring provide:

Temperature profile control of injection and production wells;

Determination of inflow (injection) intervals of the fluid;

Determination of the fluid level in the well and perforation intervals;

Identification of issues in the well.

Plus, as any fiber optic technology, distributed temperature sensing for SAGD offers:

Maximum protection of the cable against chemical and physical effects;

Longer service life;

Convenience and speed of the installation;

Operations in the well without the extraction of the cable sensor.

The SAGD wells have implemented all the advantages of fiber optic sensing. FBG sensors offer real-time, precise temperature measurements along the fiber optic cable in the wellbore. Fiber optic solutions allowed us to monitor the objects that were unapproachable before. For example, fiber optic sensors with extended temperature range were applied in the oil wells for temperature control during oil production using SAGD technology.Steam assisted gravity drainage is commonly believed to be applied for complex deployments. It aims to make the process simpler. And the fiber optic technology is good at helping it. However, the specialists should discuss and decide how fiber optic technology can fit into the development at the planning stage. Fiber optic solutions may simplify the production process.
