Tunnel Lighting Intelligent Control System Based on Ambient Light Ratio

Based on the research problems of modern tunnel lighting control technology, a tunnel lighting intelligent control system based on ambient luminosity ratio is designed, which is characterized by “car close lights bright, car passing lights dark”, intelligent analysis of system failures, etc. The core technology is LED Tunnel light group brightness automatic adjustment, python data analysis, etc. The design of the core control unit of the system is based on the STC89C52 chip, which uses the numpy module in python to matrix the data in the database through the information collected by the sensor (the light intensity inside and outside the tunnel, the traffic condition of the vehicle in the tunnel, and the working condition of the tunnel lighting equipment, etc.) Level storage and use principal component analysis and other algorithms to perform a large number of calculations and processing on the obtained data. The controller generates a corresponding PWM signal to control the brightness of the LED tunnel light group to solve the problem of excessive lighting or insufficient brightness; through other controls The components exchange information, and the downstream controller performs calculation and processing according to the control instructions sent by the previous stage and the real-time signals detected by the sensors to realize the selective brightness and automatic brightness adjustment of the tunnel section lighting, and finally achieve intelligent control, energy saving and emission reduction the goal of. In addition, we use the seaborn library and matplotlib library in python to visually display the obtained tunnel lighting equipment working condition data, and send the results to the relevant road management department. This will play an important role in greatly improving the efficiency of activities such as equipment maintenance, collecting equipment work information, and optimizing the work structure of road management. To a certain extent, it is conducive to the implementation of specific work of relevant departments.

Automatic Voice-Based Recognition For Automotive Headlights Beam Control

Driving comfort plays an important role in modern automotive technologies. One of the ways of comforting the driver is the voice-based recognition to control car headlights. The driver uttered a ‘specific word’ that is taken as an input to the proposed voice-based recognition system. The proposed mechanism then determines if the signal was either ‘high beam’ or ‘low beam’ to control the car headlights. To activate the headlight’s beam, this voice recognised signal is sent to a processing board. Mel Frequency Cepstral Coefficient (MFCC) is used in the recognition mechanism to extract the uttered word before being fed into Artificial Neural Networks (ANN) and Support Vector Machines (SVM) as a classification engine. The proposed automatic voice-based recognition was evaluated via experimental work. The results show that the proposed automatic voice-based recognition for headlights activation control involving MFCC feature works effectively in which SVM gives slightly better performance accuracy when compared to ANN. In addition to a lesser training time, the resulting accuracy using SVM in the training and testing phase is 93.595% and 91.74% respectively. Meanwhile, ANN has an accuracy of 89.39% and 88.16% in the training and testing respectively.

Root Cause Analysis and Mitigation of White Patch Formation in Automotive Headlamp

Root cause analysis of the white patch formation on the headlamp lens of a particular automobile model was carried out. SEM, FTIR, and XPS techniques were used to analyze the white patch region. Headspace GCMS and TGA were used to analyze the volatiles and curing characteristics, respectively. The white patch region shows the presence of foreign deposits and chemical attacks in the form of undulation and holes on the polycarbonate lens surface. The holes due to the chemical attack on PC lens attributes to the degradation of the polycarbonate surface. GCMS analysis reveals the release of volatiles from the reflector materials and TGA reaffirmed the releases of it from base coating applied on the reflector. These volatiles permanently settle on the inner surface of the lens and attack leading to the hazy appearance/white patch formation. A minimal volatile release could be seen in all IR-UV curable base-coated reflectors. The volatiles generation in higher quantity and their deposition on the lens in the studied headlamp is a result of higher lamp temperature and insufficient breathing. Release of volatiles can be mitigated by adopting the thermal curing of the reflector and the deposition of such volatiles on different internal parts can be minimized by selecting an appropriate breathing mechanism to facilitate proper air circulation for a given lamp design and resultant temperature.

WITHDRAWN: Design and development of multi controlled smart bike

In the Morden world the bikes are the most commonly used vehicle for the transportation. But the actual fact is there is no safety precautions in the bike. This shows the bike riding is not safety for the users like accident prevention and theft prevention. The accident prevention makes loss of conscious and sometimes it leads to death. Sometimes the rider forgets to wear the helmet, which is unsafety while traveling. Sometimes the parked bikes are missed from the place or sometimes the fuel was theft. There is no safety for the fuel level in the bikes. When there is a heavy rain the side stand of the bike will goes inside and the bike felt down which makes the damage to the bike and the leaking of the fuel. At the traffic the movement of the bike is very low that makes some crash between the bike. Some people are forgetting to turn of the head light which leads to the loss of vision for the others. During summer the atmospheric heat is very high at that time the petrol which is easily evaporated is stored as the vapour in the tank and at some pressure it makes a blast of the petrol tank, which is highly dangerous to the bike riders. This make bike travelling is very dangerous to us. This project had done with the some of the safety methods like Bike and fuel theft control, forward distance measurement for the prevention of the accident, speed control alert system, and the smart helmet for the user safety. This makes the bike riding is safety for the riders and prevent the theft which makes the bike as smart bike.

Design of ECU for Automatic Headlight Beam Control during City Driving

Automating the task of high beam switching will significantly reduce glare from oncoming vehicles and thus improving night time driving safety. To avoid temporary blindness and glare from oncoming vehicles, automatic high beam controller is developed by using an RF transmitter and receiver to control the high beam of the vehicle to low beam automatically while entering cities. This can be achieved by fixing RF transmitter at starting points of cities. Once a vehicle enters the city, the light beam control ECU in the vehicles receives signal from RF transmitter and the light beam of headlight of the vehicle is automatically switched to a low beam. Once the vehicle leaves the city by crossing RF transmitter the user input is enabled by ECU and the driver can change the beam either high or low manually according to his need. The circuit has been designed and simulated in the Proteus software and accurate switching of the high beam is achieved. This proposed system shows better performance, which will result in safe and glare-free driving at night times.

Модель системи управління пішохідним потоком міста

This article proposes a &nbsp;model of an intelligent pedestrian flow control system capable of operating in two special modes, the first of which is automatic, the second automated, taking into account the current intensities of pedestrian and car flows, is proposed. It is better to use the control system without human intervention for high-intensity sections of the road, for example, in large cities or during rush hour - during the peak load on the city's transport system. The second mode is for low-intensity sections of the road or for a certain period of time, for example, at night, when the intensity of traffic flows is low. Switching modes is realized by using a special function that will determine the mode of traffic lights depending on the intensity of pedestrian and traffic flows. The intensity in turn depends on the current time. The relationship between these two parameters is determined empirically. The mode of automatic or "rigid" regulation determines the duration of the phases of pedestrian and car traffic lights depending on the intensity of traffic flows, and the mode of automated control "on call" calculates the duration of the delay between two calls of the phase of pedestrian signaling. Also, both modes calculate the number of pedestrians and vehicles entering the system, taking into account the number of road users who left the system. The developed model will allow to refine the existing control system of switching of traffic light modes and allows to minimize accumulation of people and transport in regulated pedestrian crossings, without interfering with needs of the existing automobile or pedestrian streams.

Analysis of Failure of Body Control Module Under Various Impact and Vibration Loading

The Body Control Module regulates the operation and coordination between the different parts of the car also by using signals of some sort. The various electronic parts of the vehicle are actually controlled by a Body Control Module – from the car light to the simple door locks; each part has a module that controls it. In today’s automotive setups, these modules are operating under a single assembly – they are now controlled by the Body Control Module. It may seem like the module performs a very complex function. Hence this Body Control Module has been protected from the damage during handling and vehicle running condition. This Body Control Module is subjected to various loading conditions such as vibration loading, Impact loading, mechanical shock. One of the case studies is doing to modify the existing Body Control Module. These modifications are carried out by using Computer Aided Engineering approach and verified by the experimental results. The software being used for the simulation is ANSYS and Ls-DYNA/explicit method.

To Determine the Morphological Changes in Red Blood Cells During Storage in Blood Banks

Background: During storage of blood, the red blood cells undergo shape changes which cause fragility and endothelial interaction leading to deterioration the quality of blood in blood banks.Objectives: The aim of this study is to determine the morphological changes in red blood cells during storage in blood banks. Material and Methods: In this experimental study, a total 20 healthy volunteers between 17 to 40 years blood donors-Blood bags were taken, ten from each center i.e. MMCTH blood bank Mardan and KTH blood bank Peshawar. The specimen analysis was done at IBMS (Institute of Basic Medical Sciences) of KMU (Khyber Medical University) Peshawar. The exclusion criteria were People with anemia, hepatitis B &amp;C, HIV and syphilis. The duration of this study was six months. The inform consent was taken from each donor. The total blood 250 ml from vein in cubital fossa from each blood donor was collected in 250ml pediatric blood bag with CPDA-1 solution. Blood bags were put up in the blood bank at +2 to +6 °C and stored till 20 days. Blood specimen of about 5cc were collected in 5cc syringe from each blood bag on 0, 5th,10th ,15th and 20th day for following parameters and thin film red blood cell was prepared for examination by light microscope. Morphological changes in RBCs examined via light microscope as well as grading the RBCs status in the peripheral blood film, the occurrence of distorted RBC simply in random fields; such as +1(scored 1 to 5 altered RBC present in each field), +2 (an average of 6 to 15 altered RBC in each field), +3(16 to 25 altered RBC in each field) and +4(more than 25 altered RBC present in each field). The multi head light microscope NIKON eclipse 50 was used for examination of peripheral blood slide and we took images of randomly selected field. The image J software was used for slide examination.Results: The morphological analysis of red blood cells, count of 200 cells in each blood slide in randomly selected fields are: On day 0 the majority of cells were normally shaped (97.95±1.297 (mean±SD).With increasing storage time, the percentage of morphologically abnormal red cells rose sharply. Mean percentage of abnormal cells on day 5, 10, 15 and 20 was 28.80±10.00, 51.73±12.47, 64.78±14.66 and 68.10±7.92 respectively. This increase in percentage of abnormally shaped cells was significant as determined by one way ANOVA (p =0.001). There was a big difference of percentage of abnormal RBCs on day 0 and in = 5 to= 10 days and in = 15 to = 20 days of blood storage. The mean values of day 0 of abnormal cells was 2.05±1.297 (Mean ± Std. Deviation), abnormal cells in= 5 to= 10 days was 40.26± 16.101 (Mean ± Std. Deviation) and on day = 15 and in = 20 day was 66.44± 11.75. The mean difference from day 0 to day 20 was 63.93±10.45 (Mean ± Std. Deviation).The one way ANOVA was significant, P= 0.001.Conclusion: This study confirms the hematological and morphological changes, when blood stored at 2 °C to 6 °C for up to 21 days. The significant morphological changes were observed on 5th day of blood storage. These findings suggested that approximately a week old stored blood is as good as the fresh blood; however, significant morphological and biochemical changes begin to appear after the first week of storage and these changes aggravate with time. Hence in order to achieve best possible transfusion outcomes, stored blood up to one week can be utilized.

Research of fatal car-to-pedestrian precrash scenarios for the testing of the active safety system in China

Road safety remains a challenge with numerous Vulnerable Road Users (VRUs) suffering from injuries and death every year. Pedestrian protection using active safety systems, such as Automated Emergency Braking (AEB), is an effective measure to combat the situation. Furthermore, the perception of precrash scenarios plays an important role in active safety research. It is essential to understand and define precrash scenarios. This study aimed to apply the obtained typical car-to-pedestrian precrash scenarios from Chinese severely injured pedestrian traffic accidents to develop and test active safety systems. The National Automobile Accident In-Depth Investigation System (NAIS) recorded 467 cases from 2011 to 2018 in China, and 12 items were selected from the NAIS database as description variables for the precrash scenario. The items were divided into four categories: car, pedestrian, road, and environment. Group decision theory was applied to evaluate the importance of each variable in its category. A total of 34 basic scenarios were defined and obtained according to the extracted significant variables. These basic scenarios represented diverse fatal scenarios in China which are crucial for autonomous driving. The frequency distribution of the scenarios demonstrated that the top five scenarios covered 85.3 % of the total. Five scenarios were identified to have the common characteristic of cars going straight. Additionally, 13 detailed scenarios were obtained from the five basic scenarios by using cluster and frequency analyses. In contrast to the New Car Assessment Program (NCAP) test scenarios, weather and lighting conditions were considered in these 13 scenarios, and the driving speed before the crash were mostly distributed in the range of 40–80 km/h (20–60 km/h in the NCAP). Meanwhile, both walking and running were commonly recorded for pedestrians to cross the street from the nearside, compared with records of walking only to cross from the nearside in the NCAP. These results contribute to a reference for test scenarios of pedestrian AEB or Forward Collision Warning (FCW) in China.

Fermi-LAT Observations of V549 Vel 2017: A Subluminous Gamma-Ray Nova?

Abstract We report on the Fermi Large Area Telescope detection (with ≈5.7σ significance) as well as the multiwavelength analysis of the 2017 nova eruption V549 Vel. Unlike the recent shock-powered novae ASASSN-16ma and V906 Car, the optical and γ-ray light curves of V549 Vel show no correlation, likely implying relatively weak shocks in the eruption. Gaia detected a candidate progenitor of V549 Vel and found a parallax measurement of ϖ = 1.91 ± 0.39 mas, equivalent to a mode distance of d ≈ 560 pc (90% credible interval of 380–1050 pc). The progenitor was also observed by the 2MASS and WISE surveys. When adopting the Gaia distance, the spectral energy distribution of the progenitor is close to that of a G-type star. The Swift X-Ray Telescope detected the supersoft X-ray emission of the nova (kT = 30–40 keV) since day 236, and the inferred blackbody size is comparable to that of other novae assuming d ≈ 560 pc (i.e., R bb ∼ 5 × 108 cm). However, there is also an unknown astrometric excess noise of ϵ i = 3.2 mas found in the Gaia data, and the inferred distance becomes controversial. If the Gaia distance is accurate, the γ-ray luminosity of V549 Vel will be as low as L γ ∼ 4 × 1033 erg s−1, making it the least luminous γ-ray nova known so far. This may imply that the shock properties responsible for the γ-ray emission in V549 Vel are different from those of the more luminous events. If the nova is located farther away, it is likely a symbiotic system with a giant companion as the observed progenitor.

Melanostigma bellingshauseni sp. n. (Zoarcidae): a New Pelagic Eelpout from Large Depths in the Central Part of the Kerguelen Plateau (Southern Ocean)

A new species Melanostigma bellingshauseni sp. n. is described from large depths (1000−1010 m) in the central part of the Kerguelen plateau (the Indian Ocean sector of the Southern Ocean) The new species differs from the other species of the genus in total light coloration of body and head (light snout, jaws, nostril tubes, light brown oral cavity including respiratory membranes), an original combination of some meristic characters of the axial skeleton, fins, and the structure of the lateral line canals on the head. It has been hypothesized that species of the genus Melanostigma are not pelagic but predominantly benthic animals dwelling in excavated burrows that are used both as sites to ambush and for shelter from predators. Morphological adaptations for such lifestyle are discussed.

Development of a high resolution scanning RGB laser headlamp

Abstract Recent rapid progress in automotive lighting technology led to the emergence of headlamps featuring a large variety of light distributions that are highly adapted to provide best possible road illumination in particular traffic situations. Visual assistance systems which highlight relevant objects or project symbols to communicate with other traffic participants, further improve road safety. Implementing all these functions within a single headlamp usually requires the use of several additional modules with high and low resolution. This multitude of modules impacts the installation space, styling and cost of automotive headlamps. This paper presents a high-resolution red-green-blue (RGB) laser headlamp module which provides a good illumination of the road and can also be used for external communication purposes. A specially developed laser scanning unit, based on a bi-axial resonant micro-electro-mechanical systems (MEMS) scanner and a high-power RGB laser, serves as the technical basis. Three module concepts are designed using light simulation, constructed as computer-aided design (CAD) models and integrated into a serial headlamp package. The concepts are based on design, simulation and measurement data of the scanning unit.

A Study of High-Efficiency Laser Headlight Design Using Gradient-Index Lens and Liquid Lens

In the field of vehicle lighting, due to the diode laser, its small size and high energy conversion efficiency, it can be effectively used as the headlight source of high beam. In recent years, it was adopted by European advanced car manufacturers as a new generation of automotive headlight lighting products. The current mature technology on the market is to extend the laser beam by means of reflection and to use a single high-power laser as the light source to meet the needs of surface lighting. In this research, we propose a new integrated optical design for an automotive headlight system with the rod lens, gradient-index lens (GRIN lens) and freeform lens to expand the laser beam. With regard to the diffusion of the beam by reflection and refraction, the liquid lens is used as a switch for the high beam and low beam lights to meet the needs of vehicle lighting functions and to use low-power diode lasers to synthesize the array light source. Compared with the 24-W LED headlight module available in the current market, the energy saved by this proposed optical design can increase efficiency by an average of 33%. The maximum illuminance is 56.6 lux in the high-beam mode, which is 18% higher than the standard value. Let the laser light meet the lighting requirements of regulatory standard values even beyond.
