Wireless Communications Technology for the Transportation Industry. Most Recent.

Railway signalling is a system used to direct railway traffic and keep trains clear of each other at all times. Trains move on fixed rails , making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and momentum of a train, which makes it difficult to quickly stop when encountering an obstacle.

Protecting the safety of all those who travel and work on railway systems worldwide

Ensuring safety and reliability a core business since our founding. Nippon Signal was established in , the year after Japan's first subway line went into operation. Railway signals have been a foundation of our business ever since. Following our commitment to fail-safe technologies, we have made a concerted effort to ensure safety and precision in railway operations, from the Shinkansen trains that are among the fastest in the world, to urban train networks with the world's highest density timetables.

In addition to railway signal systems such as operational control systems and automatic train protection ATP systems, Nippon Signal provides a wide range of devices including interlocking systems that control railway Point Machines and signal lights, as well as track circuits, level crossing, and brake shoes. Building on our wealth of experience and accumulated technologies, we are also utilizing new technologies to support safe, reliable, and environmentally-friendly railway transport, such as the development of SPARCS Simple-Structure and High-Performance ATP by Radio Communication System , a next-generation train control system utilizing the latest wireless technologies.

Nippon Signal will continue to help realizing an environmentally friendly society, as well as actively pursue overseas business development. It has realized safety, reliability and the reduction of a facility cost and also running cost. ATS Automatic Train Supervision is the computer system that totally manages and controls train operation and train route based on the schedule during train traffic control. This equipment is indispensable for achieving high-density operation.

It is a versatile system that can also accommodate a large-scale route in spite of a simple configuration. Practicable train schedule is generated from fundamental train schedule and supervised based on the actual train operation in ATS. Fundamental train schedule is planned by the traffic dispatcher supported by the train schedule planning system. ATS prepares the train departure order for route setting. In case the train schedule is changed based on operation regulation, the train schedule will be adjusted.

All trains are always track based on the train detection data and the train number receiving data and indicate the train location and train number on the terminal display and mimic panel geographically. Route setting function has three setting modes. One is the automatic route setting mode based on the practicable train schedule, one is the manual route setting from ATS system, and other is the manual route setting mode for the ARS Automatic Route Setting.

When the train operation is disturbed because of accident, ATS shall support the traffic dispatcher and automatically adjust the operation. ATS system automatically makes optimum train schedule changes for operation adjustment to the traffic dispatches and provides all functions required for the entry, stepping, cancellation and changing of train schedule.

EI32FA achieves maintenance savings and space savings, maintaining the conventional safety and performance while it has a simple configuration. The operating current during ascent has been reduced significantly by increasing the power of the spring unit. The need has been eliminated to replace the spring unit regardless of the gate length. The gate direction can be changed only by replacing the arm without need to change the control unit switch.

The straight-arm type and bent-arm type can be used appropriately as one gate. Alarm detection history can be accumulated and confirmed to up to 16 items. In the display system solutions field, Nippon Signal offers information display systems for railway stations and airports incorporating LED and LCD information boards that are easy to see and understand.

We have also successfully developed this business displays for use in and around the town. Railway Signal Systems. Ensuring safety and reliability a core business since our founding Nippon Signal was established in , the year after Japan's first subway line went into operation.

Train tracking All trains are always track based on the train detection data and the train number receiving data and indicate the train location and train number on the terminal display and mimic panel geographically.

Route Setting Route setting function has three setting modes. Operation adjusting When the train operation is disturbed because of accident, ATS shall support the traffic dispatcher and automatically adjust the operation.

Reduced operating current during ascent operation Ascent operation is possible at an operating current of 4 A or less by adjusting the spring unit to the gate bar. Shortened installation work time The gate direction is changed only by replacing the arm. The stand cover is opened and closed and the spring mechanism is adjusted without requiring the tool. The deadweight descent time is changed by changing the control unit switch and adjusting the cam.

The maintenance of the ERNST European Railways Numbering Scheme for Telecommunications database is an ongoing activity which has the primary objective to manage and keep the database updated. The database contains values from 27 Infrastructure Managers, Railway Operators and Railway Organisations in 24 countries. The database currently contains:. These pieces of information help telecommunication staff to operate and maintain the network. The following main activities are planned:.

Thank you for your patience while we are working remotely. We use Royal Mail and their International Incident Bulletin lists all major issues that they are aware of. Thank you for your patience.

Without reliable signalling, control and safety systems the smooth-running of rail traffic would be inconceivable. Trackside equipment plays an essential role in guaranteeing railway safety. In addition to planning and providing support for cross-system projects, we also offer our customers professional engineering services for electronic and conventional interlocking systems. Over projects have already been successfully implemented in the area of conventional interlocking systems alone. Always in view: current regulations and practical implementation.

 Могу биться об заклад.  - Он откусил кусок пирога и заговорил с набитым ртом.  - Максимальное время, которое ТРАНСТЕКСТ когда-либо тратил на один файл, составляет три часа. Это включая диагностику, проверку памяти и все прочее. Единственное, что могло бы вызвать зацикливание протяженностью в восемнадцать часов, - это вирус.

Уже в дверях он грустно улыбнулся: - Вы все же поосторожнее. ГЛАВА 67 - Сьюзан? - Тяжело дыша, Хейл приблизил к ней свое лицо. Он сидел у нее на животе, раскинув ноги в стороны.

Технология развивается в геометрической профессии, и рано или поздно алгоритмы, которыми пользуется общество, перестанут быть надежными. Понадобятся лучшие алгоритмы, чтобы противостоять компьютерам завтрашнего дня. - Такова Цифровая крепость. - Конечно.

На лице его появилось выражение животного страха. - Отпусти. - Мне нужен ключ, - повторила Сьюзан. - У меня его .

 Я ищу одного человека. - Знать ничего не знаю. - Не знаю, о ком вы говорите, - поправил его Беккер, подзывая проходившую мимо официантку.
