DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a passenger guidance system according to the present embodiment.

A plurality of passenger guide systems 10 are provided along a track 12 and a plurality of train control sections for sequentially relaying and transmitting position information of a train 16 to a train control main unit (ZC) 14. Device (WRS) 18 and multiple WRSs
A passenger guidance device 20b that intercepts the position information transmitted between the two and provides a passenger guide based on the intercepted position information;
Is provided.

On the train 16, an on-board radio device (VRS)
The VRS 22 wirelessly transmits the train information to the WRS 18 at a predetermined transmission timing. The train information includes various information such as train attribute information (for example, train number, train type, destination, next stop station code, and the like). These VRS22 and WRS18
Are synchronized with each other, and share the transmission timing of the train information from the train 16. Since the train information transmitted from the VRS 22 is received at each WRS 18 with a delay corresponding to the distance from the transmission timing to the WRS 18, the difference between the reception timings of a plurality (at least two) of the WRSs 18 and the From each position of the plurality of WRSs 18 having a difference in reception timing, the orbit 12
The position of the train 16 can be detected as the position of the VRS 22 above. Each train 16 is equipped with an on-board controller 23, which controls the operation of the train 16 and
The control of the RS 22 is performed. The VRS 22 acquires train information from a storage unit (not shown) and transmits the train information.

[0013] To each ZC 14, information (hereinafter, referred to as transmission information) including information indicating each delay time as position information and train information (hereinafter, referred to as transmission information) is transmitted from each WRS 18 by radio (for example, by microwave). The transmission information is ZC14
Is transmitted from the WRS 18 on the far side to the WRS 18 on the near side. Each WRS 18 superimposes the information received from the VRS 22 on the transmission information received from the distant WRS 18 and transmits the information to the WRS 18 near the ZC 14. That is, the transmission information is transmitted by sequentially relaying a plurality of WRSs 18 provided along the track 12. In addition, a communication channel (for example, a frequency or a code) is set for each WRS 18, and mutual interference of transmission information from a plurality of WRSs 18 is prevented. Also, each WRS 18 is a ZC
The transmission information is transmitted with the transmission power at which the transmission information reaches at least two WRSs 18 on the 14 side. As a result, even if the adjacent WRS 18 becomes unable to relay due to a failure or the like, the WR one bit ahead of the failed WRS 18
Transmission and reception of transmission information can be performed via S18.

The ZC 14 is provided for each predetermined jurisdiction section and collects transmission information from a plurality of WRSs 18 in the jurisdiction section. Based on the aggregated transmission information, ZC 14
The position and attribute of the train 16 within the jurisdiction section are detected. Then, the ZC 14 generates control information (for example, speed regulation information or signal control information) for the train 16 based on the on-rail status of the plurality of trains 16 in the jurisdiction section and the speed regulation in the jurisdiction section. ZC 14 transmits this control information to train 16 via WRS 18.

A passenger guide device 20a is provided adjacent to the ZC 14. The passenger guidance device 20a is configured to transmit the passenger guidance information at the station 24a based on the transmission information (for example, information for indicating the approach of the train, information for indicating the estimated arrival time of the train, information for indicating the position of the train, or Information indicating the delay status of the train).
At the station 24a, the passenger guidance based on the passenger guidance information is performed, for example, as voice output and / or display output.

The ZC 14 is located at, for example, the station 24
a, there is a station 24b without the ZC 14 in the same jurisdiction in the system configuration of FIG. This station 2
In order to perform the passenger guidance in 4b, the passenger guidance system 10 according to the present embodiment is provided with a passenger guidance device 20b. The passenger guidance device 20b intercepts transmission information transmitted to the ZC 14 by being sequentially relayed in the WRS 18. The passenger guidance device 20b generates passenger guidance information based on the intercepted transmission information, similarly to the passenger guidance device 20a. At the station 24b, passenger guidance is performed based on this passenger guidance information.

The passenger guidance in each of the passenger guidance devices 20 (20a, 20b) corresponds to a WRS in a predetermined section (hereinafter referred to as an information acquisition section) ZI (ZIa, ZIb) in a jurisdiction section.
18 based on the transmission information. That is, the passenger guidance device 20 extracts the information of the WRS 18 in the information acquisition section ZI from the transmission information, and generates passenger guidance information based on the extracted transmission information. In order to extract information, the passenger guidance devices 20 are each provided with a storage device (not shown ZC1).
4, a storage device or a DB 28), and stores in the storage device identification information for identifying the WRS 18 in the information acquisition section ZI (for example, the ID of the WRS 18 or information indicating the communication channel of the WRS 18). I do.
The passenger guide device 20 refers to the identification information and extracts transmission information from the WRS 18 in the information acquisition section ZI from the transmission information. More specifically, for example, the passenger guidance device 20
b is the ID of the WRS 18 included in the intercepted transmission information and the WRS in the information acquisition section ZI registered in the DB 28 in advance.
18 (registered ID), and from the transmission information,
The transmission information corresponding to the registration ID is extracted. Alternatively, the passenger guidance device 20b may extract transmission information transmitted on a communication channel (for example, a frequency or a code) for transmitting information from the WRS 18 in the information acquisition section ZI registered in the DB 28 in advance. In this case, the passenger guidance device 20b may switch the communication channel itself of the transmission information to be received, for example, by switching the reception characteristics of the reception antenna (for example, by switching the reception frequency band [communication channel]), or Transmission information of a registered communication channel may be selectively extracted from transmission information intercepted including signals of a plurality of communication channels.

In the passenger guidance system 10 according to the present embodiment, the WRS (18a, 18b) located closer to the ZC 14 than the passenger guidance device 20b moves in the direction of the passenger guidance device 20b (ie, farther from the ZC 14). The transmission information can also be transmitted. Because of this, these WR
S (18a, 18b) includes transmission antennas (26a, 26b) pointing in the direction where the passenger guidance device 20b is located. These transmitting antennas (26a, 26b)
Since it is necessary to transmit transmission information for controlling the train to the C14 side as well, at least the direction of the WRS 18 adjacent to the side closer to the ZC14 and the passenger guidance device 20
It is configured as an antenna having directivity in the direction of b. The transmission information is a WRS located on the far side from ZC14.
Since the information is transmitted to the WRS 18b located closer to the passenger guidance device 20b, the passenger guidance device 20b can easily transmit information in this direction (that is, transmission information from the WRS 18 located farther from the passenger guidance device 20b as viewed from the ZC 14). Can be intercepted. Further, by providing the above configuration, the WR on the side near ZC14 with respect to the passenger guide device 20b.
It is possible to acquire the transmission information from S (18a, 18b), whereby it is possible to set the information acquisition section ZI on both the upside and the downside of the station 24b regardless of the positional relationship with the ZC14. Therefore, it is possible to provide passenger guidance information for both ascending and descending trains more easily and more accurately.

The position information in the present embodiment is transmitted, for example, as information indicating each delay time. For this reason,
ZC14 (passenger information device 20a) and passenger information device 2
Correlation data indicating the correlation between the delay time and the distance is stored in a storage device provided at 0b (for example, a storage device not shown provided inside the ZC 14 or the DB 28). FIG. 2 shows an example of the correlation data. According to the correlation data, it is possible to determine which subsection (hereinafter, referred to as a segment, sg in FIGS. 1 and 2) the train 16 is based on the delay time. The storage device stores, as correlation data, a delay time range (for example, a minimum value and a maximum value of delay time) for each segment for each driving direction (up / down) and WRS attribute information (for example, WRS number). By referring to the correlation data, the passenger guide device 20 can determine the segment on which the train is located. For example, WR for an up train
Delay time = 20 (nanosecond; n) as position information of S1
s), delay time = 45 as position information of WRS2
When (nanoseconds; ns) is obtained, the segment (sg) m-1 can be selected as a segment satisfying these conditions.
