JR Tokai released a new commuter train 315 series on December 3rd. In addition to its appearance and inside the car, there were also explanations on characteristics such as improving barrier -free equipment and cooling functions and strengthening in -car security. Introducing the 315 series along with photos taken in the public. [Photo] New vehicle 315 series, appearance and public publication (78 pieces in total) The new vehicle 315 series, "Because it is a vehicle used by many people every day, everyone feels kind and peace of mind. I want to provide a moving space that I can do. " The exterior is based on the concept of "advanced x accomplishment", with high -brightness LED sign lamps in a geometric front shape using a straight line, while feeling familiar with the color scheme in which the corporate color orange and white are harmonized. For design to do. The seats inside the car are all -long seats, and the interior is designed to gain a sense of openness due to the spread of the space based on the concept of "a gentle and secure comfortable moving space." The 315 series has already participated in three trains in about a month after the C1 formation participated in the Japanese vehicle (manufactured by Nippon Vehicle) at midnight on November 6th. In the press release, it was exhibited alongside the K51 formation of the 211 series 0s manufactured in the JNR era, using the 315 series C2 formation. The C2 train released this time is "Kuha 314-2", "Moha 315-504", "Moha 315-4", "Saha 315-502", "Saha 315-2", "Moha 315-503", "Moha 315" -3 "Kuha 315-2". According to the main specifications of the distributed pamphlet, the vehicle type / car type (abbreviated) / empty vehicle weight of the 315 series (8-car train) is "Kuha 314-0 / TC'1 / 34.5T" "Kuha 314-0 / 34.5T". Moha 315-500 / M2 / 34.9T "" Moha 315-0 / M1 / ​​37.0T "" Saha 315-500 / T2 / 31.0T "" Saha 315-0 / T1 / 30.4T "" Moha 315-500 / M2 / 34.9T, "Moha 315-0 / M1 / ​​37.0T", "Kuha 315-0 / TC1 / 33.9T". The capacity is 133 for 1 car, 154 for cars 2-7, and 139 for car 8. The body length is 20,100mm, the body width is 2,978mm, the roof height is 3,630mm, and the floor surface is 1,140mm. The maximum speed is 130km/h, a startup acceleration of 2.6km/h/s, a deceleration of 4.3km/h/s (maximum common use), 5.1km/h/s (emergency). The bogie is "Volstares trolley / dandem -type shaft box support method", the control method is "VVVF inverter control (with abnormal output improvement function)", and the brake method is "regenerative brake combined electric command type air brake". Equipped with "ATS-ST", "ATS-PT (with EB function)", "Digital train radio", "TE device", and "protective radio (with automatic call function)" as security devices. "LTE data communication between vehicles and grounds" was adopted. It was also introduced that this 315 series was the first vehicle created as the "N-Qualis" brand of the Japanese vehicle. Both inside and outside the vehicle, you can see the "N-Qualis" logo along with the manufacturer name (Japanese vehicle). "N-Qualis" is a next-generation platform that has evolved by polishing "Quality", "Lifelong", and "Safety". The structure is smooth by smoothing the surface and arranging structural members efficiently. The striped sticker has also been significantly reduced. In addition to the integrated press type, the number of important welded liners is reduced, and the NS bogie that realizes high driving stability and excellent riding comfort, as well as state monitoring technology that uses vehicle data to detect abnormalities early. Regarding the 315 bogie, there is also an explanation that the reliability has been increased by using a structure that integrates the twist and flattening, and the welding part of the bogie frame has been reduced by 60 % compared to the 313 series. rice field. In the 315 series, constant state monitoring is possible by introducing data communication devices between vehicles and ground. In all 315 series vehicles, the operation status of each device is converted into data and sent to the ground (such as depot) in real time. Perform automatically analysis on the server, and workers confirm the results. This can detect signs of abnormalities and prevent trains. By utilizing the data of the vehicle status for maintenance, the occurrence of vehicle problems can be suppressed. The main features of the in -car facilities include four things: enhancement of barrier -free equipment, improving sitting comfort, improving cooling function, and comfortable in -car space. As for barrier -free equipment, one wheelchair space is provided in all vehicles, and the space is cleared by displaying the wheelchair mark and stroller mark on the floor. The priority seats provided at the end of the vehicle are also color -coded with the general seats, improving visibility. Wheelchair -compatible toilets are installed in all trains (C2 trains published in the news are installed in the first car). In addition to reducing the steps between the vehicle and the platform, the indicator indicator on the vehicle on the door is a full -color LCD display corresponding to the color universal design, enabling visual display such as operation information and station information. In order to improve the cooling function, we introduced the first AI automatic learning and control optimization function in Japan. In the past, while automatically controlling the vehicle to the set temperature, if the environment changes (such as congestion, increased humidity, etc.) occur, and the temperature inside the vehicle increases, the conductor needs to be manually lowered the set temperature. was there. By using the cooling function as AI control, AI automatically learns various data (inside temperature, outside temperature, humidity, riding rate, etc.) at the time of manual correction of the set temperature, and creates an optimized cooling control parameter. Based on this, the air conditioning will be controlled in a detailed way to maintain a comfortable in -car environment. We are also working on improving safety, and we have installed three emergency calls per car, including emergency door cocks that have been installed from vehicles, and five in -car security cameras per car have been enhanced. 。 In the emergency call device, when the passenger presses the button in an emergency, the buzzer sounds and can talk directly with the crew. When the emergency call device is handled, it is automatically notified to the command center, and the image of the in -car security camera is transmitted to the driver's cab and the command center in real time, so it is confirmed early and promptly responded even in the event of an abnormality. You will be able to do it. We strive to reduce environmental impact, and reduce power consumption by adopting high -efficient SIC elements for power conversion devices. As a result of simulation between Nakatsugawa and Nagatsugawa and Nagoya and Tokaido Main Line Toyohashi -Ogaki (running at the maximum speed of 120 km/h), the power consumption of the 315 series was reduced by about 35%compared to the 211 series. After the summer of 2022, the first emergency driving power storage equipment for JR Tokai's conventional vehicles will be installed sequentially. Even during long -term power outages due to the occurrence of natural disasters, the driving system can be operated with a large lithium -ion battery, and even if there is no power supply from the overhead wire, it can travel to a safe place, and air conditioning equipment in the car. Is also possible. In the press release, Naoyuki Sugiyama, the director of the JR Tokai Railway Business Division, responded to the surroundings. In the greeting, the 315 series was "for the first time in about 22 years as a conventional train commuting train. The aim is to improve safety, stability and comfort, and reduce environmental impact. From the perspective of capturing the needs of the world, we think that we have been able to create vehicles that can be used safely and with peace of mind, taking into account the barrier -free facilities and security. " "I wanted to create a vehicle that can be used with peace of mind because it is a commuting -type vehicle that local customers are used every day. I want to use it for a long time, make it a familiar car. But there is, "he commented. In the Q & A session, there was also a question about the ride comfort of the 315 series, saying, "The bogies introduced today have been created from the perspective of improving safety and improving ride comfort, and new technology has been introduced. Sugiyama replied, "I think the ride has improved," "I think it was basically reduced and the riding comfort was solid," Sugiyama replied. The 315 series operation start date is March 5, 2022. It is introduced between Nakatsugawa and Nagoya on the Chuo Main Line, and in 2023 vehicles in the same section will be unified to the 315 series (excluding limited express trains). Along with this, the 211 series 0 series (8 cars in total), which was inherited from the National Railways, including the K51 formation used in the press release, will retire in mid -March 2022. After that, the 211 series, 213 series, and 311 series, which were introduced in the early days of JR Tokai, will be replaced with 315 series. In addition, between Nakatsugawa and Nagoya on the Chuo Main Line, in addition to the 211 series, the 313 series is also active. By unifying the vehicle to the 315 series, the 313 series is "I think it will be transferred to either, but the details are still adjusted" (Mr. Sugiyama). In addition, after the introduction of the 315 series, there were questions about the operation of the vehicle as the number of passengers decreased due to the corona evil, and the future installation of the vehicle between Nakatsugawa and Nagoya, but all were "future situations. While looking at, I would like to report when the timing can be announced. "
