Description

  The present invention relates to a railway vehicle broadcasting service providing system that performs broadcasting and content distribution in a railway vehicle as a high-speed moving body.

  In recent years, with the increase in service channels, etc., terrestrial analog broadcasting is shifting to terrestrial digital broadcasting. Conventionally, multi-channel broadcasting services using Ku waves targeting indoor fixed stations are also being implemented for satellite waves.

  Satellite broadcasting is intended for broadcasting services to remote islands and mountainous areas that affect radio wave relaying, provision of multipurpose broadcasting, and the like. Currently, BS (Broadcasting Satellite) broadcasting and CS (Communication Satellite) broadcasting are in practical use.

  As such a satellite broadcasting system, there is a system shown in Patent Document 1 that can be applied to a moving body or the like, or a system shown in Patent Document 2 that can correspond to existing media as well as broadcasting.

  On the other hand, in both the BS and CS systems described above, the Ku wave is used as the carrier wave distributed from the geostationary satellite. Therefore, a parabolic antenna is used for reception due to the nature of the radio wave, and the antenna is always a geostationary satellite for reception. It was installed in the direction.

  For this reason, in the realization of broadcasting services to mobiles using geostationary satellites, it is necessary to accurately point the mobile station's antenna at all times, so that the attitude control is complicated. And the cost was high.

  In addition, in Ku waves, the carrier power is limited by the amount of the high frequency, and the power is lower than that of other carrier pairs. Therefore, it is necessary to use a parabolic antenna with a high gain as the antenna on the mobile station side. Therefore, the antenna becomes large and is not suitable for application to a mobile station.

  Furthermore, in order to receive broadcasts on a mobile object such as a rail vehicle using terrestrial waves, it is necessary to continue to receive radio waves across many reception areas. Therefore, it is necessary to automatically switch the receiver, and therefore receiving equipment such as tuner equipment becomes large.

  Also, when receiving broadcast waves using ground waves with a moving body such as a railroad vehicle, if the moving body moves away from the broadcasting base station or key station, the reception intensity of the radio wave will naturally decrease, so a stable service is always provided. It was difficult. Also, these reception conditions change from moment to moment.

  Furthermore, when receiving broadcast waves using ground waves with a moving body such as a railway vehicle, radio waves do not always propagate through flat spaces, but areas that interfere with radio wave propagation such as mountains, buildings, and tunnels There are cases where it is difficult to receive radio waves because it cannot be avoided.

  In addition, data communication between the ground and the vehicle in railroad vehicles is difficult to download large amounts of data while moving, so download it by a base transmission system at a specific stop position such as a station premises or a maintenance base, Real-time image broadcasting has been difficult to distribute because data storage type services are at the center.

  From the above, it has been difficult for mobile objects such as railway vehicles to broadcast images that are useful for quick response such as news, market conditions, and wide-area temporary information.

On the other hand, since the body of a railway vehicle has a metal structure, in order to directly receive broadcast waves from the outside, in the carrier wave VHF band currently used for terrestrial waves, the opening of a window or the like is related to the wavelength. Even if there was a part, the environment of wave guide to the vehicle was not stable and it was difficult to receive directly.

  As described above, the conventional satellite broadcasting system uses a Ku wave of several tens of GHz, and because of the nature of the radio wave, there is a straight line (directivity). In this case, the antenna direction is always directed to the geostationary satellite. It was necessary to keep.

  Also in this radio wave carrier output, in order to reduce the influence of electromagnetic waves on the human body and the environment due to radiation at high frequencies, the output is limited, and the receiving antenna used for this also has a diameter of about 30 cm to obtain a reception gain It had to be configured using a parabolic antenna.

  An object of the present invention is to provide a railway vehicle broadcasting service providing system capable of easily and inexpensively realizing broadcasting and communication in a high-speed moving body such as a railway vehicle.

  In order to solve the above-mentioned problems, the present invention provides a system for providing a broadcasting service by a railway vehicle. The receiving means is arranged in the railway vehicle and receives a broadcast signal. The receiving means is arranged in the railway vehicle, A cable that transmits the received broadcast signal within the train composition, a control device that is disposed in each vehicle of the rail vehicle, and that decodes the broadcast signal into a digital image, and is disposed in each vehicle of the rail vehicle. And a display for receiving and displaying a digital image by the control device.

  In the present invention, a broadcast signal including video and audio information possessed by the master station is sent from the ground station to a geostationary satellite, for example, via a Ku-band uplink transmission path, and then sent to the geostationary satellite. Transmitted to the service area via the S-band downstream transmission path, taken into the railway vehicle by the receiving means arranged in the railway vehicle, transmitted in the train train formation by cable, and broadcast by the control device The signal is decoded into a digital image and provided to the passenger on a display.

  According to the present invention, broadcast distribution that can contribute to improvement of services, such as real-time information can be obtained instead of data storage type broadcast, content, and data distribution by data download from a conventional base station for users of railway vehicles. Accordingly, it is possible to provide a railway vehicle broadcasting service providing system that can easily and inexpensively realize broadcasting and communication in a high-speed moving body such as a railway vehicle.

  FIG. 1 shows a railway vehicle broadcasting service providing system according to a first embodiment of the present invention. In a satellite broadcasting system including a ground station facility, a geostationary satellite, and a mobile station facility, a high-speed moving body that is a mobile station facility is shown. In the railway vehicle, the S band digital satellite broadcasting service is provided to the passenger.

  As shown in FIG. 1, in this embodiment, it consists of a ground station 10 such as a broadcasting station as a ground station facility, a geostationary satellite 20, and a railway vehicle 30-1 as a mobile station facility.

  The ground station 10 sends video and audio information to the geostationary satellite 20 via the Ku band uplink transmission path.

  The geostationary satellite 20 is transmitted to the service area via the S-band downlink transmission path. The geostationary satellite 20 is demodulated and amplified by a signal processing device provided in the satellite body, and then converted into an S band in real time and radiated, so that a mobile station such as the railway vehicle 30-1 of the present embodiment is constantly being used. A transmission signal from the geostationary satellite 20 can be received. Usually, this transmission signal is multiplexed, and a mobile station such as the railway vehicle 30-1 of this embodiment can arbitrarily select and receive a plurality of audio and video programs.

  The geostationary satellite 20 is equipped with a large-diameter antenna for transmitting with sufficient electric field strength in the service area. Since this transmitting antenna covers a wide area, an independent beam is formed for each area range. Then transport. By using a geostationary satellite equipped with these functions, a small-sized antenna can be used without having a large parabolic antenna of several tens of centimeters in the direction of the geostationary orbit of the satellite as in a broadcasting system using a conventional satellite. Can be sufficiently received, and the railway vehicle 30-1 of the present embodiment also includes the receiving device 31 using the small antenna 31A.

  As described above, the railway vehicle 30-1 includes the receiving device 31 having the small antenna 31A that can receive the downward S wave from the geostationary satellite 20, and the broadcast signal received by the receiving device 31 of the railway vehicle 30-1. An RF cable 32 that is routed in the train, a control device 33 that is arranged in each vehicle and decodes a broadcast signal from the RF cable 32 into a digital image, and a digital image that is arranged in, for example, the upper part of the door of each vehicle by the control device 33 And a display 34A for displaying and a public display 34 having a controller 34B for controlling the display on the display 34A.

  In the present invention, the video and audio information held by the master station is sent from the ground station to a geostationary satellite via, for example, a Ku-band uplink transmission path, sent to the geostationary satellite, and then transmitted from the geostationary satellite to the geostationary satellite, for example, S band. Sent to the service area via the road. In this service area, in addition to a conventional fixed station, a mobile station that travels at a high speed such as a railway vehicle as in the present embodiment can receive the broadcast service on the railway vehicle.

  A geostationary satellite is demodulated and amplified by a signal processing device provided in the satellite body, and then converted and radiated in real time to, for example, an S band (2.6 GHz, etc.), so that a mobile station such as a railway vehicle constantly It becomes possible to receive a transmission signal from a satellite.

  Usually, this transmission signal is multiplexed, and a mobile station such as a railway vehicle can arbitrarily select and receive a plurality of audio and video programs.

  The geostationary satellite used for this is equipped with a large-diameter antenna in order to transmit with sufficient electric field strength in the service area. Further, since this transmitting antenna covers a wide area, an independent beam is formed and conveyed for each area range.

  By using a geostationary satellite having these functions, it is possible to reduce the size of a large parabolic antenna of several tens of centimeters, such as a broadcasting system using a conventional satellite, without always facing the geostationary orbit of the satellite. It is possible to sufficiently receive with the antenna.

  In the present invention, since a geostationary satellite is used, the service area is wider than that of a ground station. By using the S wave as the downlink carrier wave from the geostationary satellite to the ground, it is possible to use the indirect wave as well as the direct wave. As a result, due to this multipath propagation, as a characteristic that does not exist in conventional terrestrial carrier waves, there is a characteristic that the radio wave reaches the deep part while reflecting and entering from a few openings such as windows in the building environment. It can be built into a small receiver with a relatively small antenna.

  Further, since the reception sensitivity is a frequency lower than that of the Ku wave, for example, the 2 GHz band, the carrier output to the ground has a relatively sufficient margin, so that reception stability can be obtained. By using these, live video and audio can be easily applied to a moving body such as a railway vehicle.
