The passenger guide device is connected to the passenger guide terminal via LAN. The passenger guide device is connected to a noise measurement device for detecting a noise level around the place where the device is installed in order to adjust the voice output level of the announcement based on the initial value and the noise level of the voice output level set by the passenger guide terminal.

Description

本発明は、駅構内のホームあるいはコンコースに設置される旅客案内システム及び旅客案内システムによる旅客案内方法に関するものである。   The present invention relates to a passenger guidance system installed on a platform or a concourse in a station, and a passenger guidance method using the passenger guidance system.

従来の旅客案内システムでは、駅の案内放送を出力する際、その案内放送の音声出力レベルは、列車到着前後の案内種別、列車在線中の列車騒音、乗客の増加に起因する駅構内の騒音の大きさに関係なく、予め定めた一定の値に予め設定されたレベルで出力を行っていた。
しかし、従来システムでは次のような問題点がある。
すなわち、列車到着時の案内放送においては、列車の到着時の進入騒音により案内放送が聞きづらくなる。
この改善策として、列車到着時の案内放送を基準として出力レベルを設定することが考えられる。これにより、列車到着時には案内放送が聞きやすくなる利点があるが、列車到着前の案内放送において、列車到着時と同じ音声出力レベルで案内放送を行った場合、音声出力レベルが過大となりホーム乗客に不快感を与える問題が発生する。
また、ホーム乗客に不快感を与えるのを避けるため、音声出力レベルを制限すると、朝ラッシュや夕ラッシュ時等には、乗降にかかわりなく多数の乗客がホームに押し寄せるため、乗客の話し声などが起因となる騒音が発生し、案内放送が聞きづらくなるという問題が生じる。 In the conventional passenger guidance system, when the station guidance broadcast is output, the voice output level of the guidance broadcast is the guidance type before and after the arrival of the train, the train noise on the train line, the noise in the station premises due to the increase in passengers. Regardless of the size, output is performed at a preset level at a predetermined constant value.
However, the conventional system has the following problems.
That is, in the guidance broadcast when the train arrives, it becomes difficult to hear the guidance broadcast due to the approach noise when the train arrives.
As an improvement measure, it is conceivable to set the output level based on the guidance broadcast when the train arrives. As a result, there is an advantage that the guidance broadcast is easy to hear when the train arrives. An unpleasant problem occurs.
In addition, if the audio output level is restricted to avoid discomfort to the home passengers, many passengers will come to the home during morning rush or evening rush, regardless of getting on and off. This causes a problem that it becomes difficult to listen to the guidance broadcast.

この観点から、案内放送の出力レベルを時間帯で管理することも考えられ、例えば、朝夕のラッシュ時間帯を設定し、その時間帯に音声出力レベルを自動的に通常時より数dB上げることにより、ラッシュ時に騒音が増大した場合にも案内放送が聞きやすくなる。
しかし、朝・夕ラッシュ時間帯に乗客が増加することはあくまで予測であり、実際にはラッシュ時間帯でも、発着する列車、特定の時間帯によっては閑散となる場合があり、このようなときには、騒音がさほど高くないにもかかわらず、音声出力のみが高くなるため、ホーム乗客に不快感を与える問題が発生する。また、朝夕のラッシュ時以外にも乗客が増加する場合もあるため、突発的な騒音に対応した案内放送ができない。 From this point of view, it is also conceivable to manage the output level of the guidance broadcast in time zones, for example, by setting a morning and evening rush time zone, and automatically raising the audio output level by several dB from the normal time in that time zone Even when noise increases during rush hours, it is easier to listen to the guidance broadcast.
However, the increase in passengers during the morning and evening rush hours is just a prediction, and even in the rush hours, it may be quiet depending on the trains that arrive and depart, depending on the specific time zone. Even though the noise is not so high, only the sound output becomes high, which causes a problem of discomforting home passengers. In addition, since the number of passengers may increase other than during the morning and evening rush hours, it is not possible to broadcast information in response to sudden noise.

これらの問題を解決するため、駅員等の操作者が列車到着時あるいは乗降する乗客の多少に応じて、その都度案内放送の出力レベルを手動で調整することも考えられるが、ホーム数が多い駅では操作者の負担が非常に高くなり、また、最適な調整には熟練を要する。   In order to solve these problems, it is conceivable that operators such as station staff adjust the output level of the guidance broadcasting manually each time the train arrives or gets off and on the train. Then, the burden on the operator becomes very high, and skill is required for optimal adjustment.

従来の旅客案内システムとして、次のような先行技術が挙げられる。   The following prior art can be cited as a conventional passenger guidance system.

そこで、上記の問題点を解決するため、本発明では、旅客案内装置が設置されたコンコースやホームの騒音レベルに応じて、自動的に最適な音声出力レベルを設定することにより、例えば列車到着時あるいはラッシュ時にも、駅構内の乗客に音声案内を確実に伝達可能とするとともに、騒音レベルが低いときにも駅構内の乗客に不快感を与えないようにすることを目的とする。   Therefore, in order to solve the above problems, the present invention automatically sets an optimal voice output level according to the noise level of the concourse or home where the passenger guidance device is installed, for example, arrival of a train It is an object of the present invention to make it possible to reliably transmit voice guidance to passengers in a station even during times or rush hours, and to avoid discomfort to passengers in a station even when the noise level is low.

図１は本発明を実現するシステム構成のブロック図である。
旅客案内端末３は、中央の列車集中管理システム等から通信ケーブルを介して受信した、駅に発着する列車の運行情報に基づいて、ＬＡＮ経由で駅構内のコンコースあるいはホームに設置された旅客案内装置６の案内画像表示データや音声案内等の制御情報を個別に送信するとともに、これらの情報の詳細設定などを行うための端末であり、旅客案内端末３はデスクトップ型またはノート型パソコン（ＰＣ）などの汎用装置が使用できる。駅員等の操作者は、案内放送の出力レベルをキーボード、マウス等の入力装置４により入力し、設定値入出力部１１が出力する設定値をモニタ５で確認しながら、ＬＡＮ経由で、各旅客案内装置６の設置箇所に応じて音声出力レベルの初期値を調整する。 FIG. 1 is a block diagram of a system configuration for realizing the present invention.
Passenger guide terminal 3 is a passenger guide installed on a concourse or platform in a station premises via a LAN based on train operation information received from a central train central management system or the like via a communication cable. The terminal 6 is a terminal for individually transmitting control information such as guidance image display data and voice guidance of the apparatus 6 and for performing detailed setting of the information. The passenger guidance terminal 3 is a desktop type or notebook type personal computer (PC). General-purpose devices such as can be used. An operator such as a station staff inputs the output level of the guidance broadcast through the input device 4 such as a keyboard and a mouse, and confirms the set value output from the set value input / output unit 11 on the monitor 5 while checking each passenger via the LAN. The initial value of the audio output level is adjusted according to the installation location of the guidance device 6.

各旅客案内装置６は、各線の発着情報、遅延情報などを表示するディスプレイ（図示せず）と、これらを音声で案内するスピーカ、音声増幅器（アンプ）などからなる放送設備７とからなり、コンコースあるいはホームの所定箇所に測定する箇所に設置されたマイク等の集音装置１と、集音装置１の出力に基づいて騒音レベルを測定する騒音測定装置２が接続されている。
なお、集音装置１は、音声出力を行うホームあるいはホームの騒音レベルを広範囲にかつ正確に集音できるよう、騒音が常時発生する場所を避けて設置することが望ましい。 Each passenger guidance device 6 includes a display (not shown) for displaying arrival / departure information and delay information of each line, and a broadcasting facility 7 including a speaker, an audio amplifier (amplifier) and the like for guiding these by voice. A sound collecting device 1 such as a microphone installed at a place to be measured at a predetermined place on the course or home, and a noise measuring device 2 for measuring a noise level based on the output of the sound collecting device 1 are connected.
It is desirable that the sound collecting device 1 be installed avoiding a place where noise is always generated so that sound can be collected over a wide range and accurately in the home noise level.

旅客案内装置６は、騒音測定装置２から受信する騒音の測定値と、旅客案内端末３からＬＡＮ経由で受信した案内放送の音声出力レベルの初期値と、騒音の大きさに対応した案内放送の出力レベル設定値から、案内放送の出力レベルを決定し、放送設備７からこの出力レベルでの音声案内を行う。   The passenger guidance device 6 receives the noise measurement value received from the noise measurement device 2, the initial value of the voice output level of the guidance broadcast received from the passenger guidance terminal 3 via the LAN, and the guidance broadcast corresponding to the noise level. The output level of the guidance broadcast is determined from the output level setting value, and the voice guidance is performed at this output level from the broadcast facility 7.

図２は、図１に示した旅客案内端末３のブロック図を示している。
旅客案内端末３では、入力装置４より入力した各コンコースあるいはホームに応じた音声出力レベルの初期値を、設定値入出力部１１によりモニタ５に表示するとともに、入力された初期値は、設定値解析部１２により妥当性のチェックが行われた後、データ送信部１３の処理を起動し、ＬＡＮ経由でデータを旅客案内装置６に送信する。
なお、このデータ送信は、操作者が入力装置４により出力レベル設定値を送信するための入力を行う度に、データ送信部１３により旅客案内装置６に送信される。 FIG. 2 shows a block diagram of the passenger guidance terminal 3 shown in FIG.

旅客案内装置６は騒音測定装置２から送信される、コンコースあるいはホームにおける騒音の測定値を、騒音測定値受信部２３により受信し、出力レベル決定部２４に送信する。旅客案内装置６から案内放送の出力要求をする際に、出力レベル決定部２４にて、騒音の測定値と出力レベル設定ファイル２２に格納した案内放送の出力レベル設定値から、案内放送の出力レベルを決定する。また音源部２５に出力文章情報と共に出力レベル情報を送信する。
音源部２５は、出力文章情報を基に音声合成を行い、出力レベル決定部２４から送信された出力レベル情報を加味し音声出力データし、放送設備７に送信する。 The passenger guidance device 6 receives the measured value of the concourse or home noise transmitted from the noise measuring device 2 by the noise measured value receiving unit 23 and transmits it to the output level determining unit 24. When the output of the guidance broadcast is requested from the passenger guidance device 6, the output level determination unit 24 determines the output level of the guidance broadcast from the measured value of noise and the output level setting value of the guidance broadcast stored in the output level setting file 22. To decide. The output level information is transmitted to the sound source unit 25 together with the output text information.
The sound source unit 25 performs speech synthesis based on the output text information, takes the output level information transmitted from the output level determination unit 24 into audio output data, and transmits the audio output data to the broadcast facility 7.

なお、この実施例では、旅客案内装置６内の出力レベル決定部２４により、客案内端末３から送信される音声出力レベルの初期値と、騒音測定値受信部２３により受信した騒音の測定値に基づいて最終的な音声出力レベルを決定したが、騒音測定値受信部２３により受信した騒音の測定値をＬＡＮ経由で旅客端末３に送信し、設定値入出力部１１で、音声出力レベルの初期値と、騒音測定値受信部２３により受信した騒音の測定値に基づいて最終的な音声出力レベルを決定してもよい。
さらに、騒音測定値受信部２３により受信した騒音の測定値を時間毎に記憶し、音声出力レベルの初期値を長期的な時定数で学習するようにしてもよい。 In this embodiment, the output level determination unit 24 in the passenger guidance device 6 converts the initial value of the voice output level transmitted from the passenger guidance terminal 3 and the noise measurement value received by the noise measurement value reception unit 23. The final sound output level is determined based on the noise measurement value received by the noise measurement value receiving unit 23 and transmitted to the passenger terminal 3 via the LAN, and the set value input / output unit 11 sets the initial sound output level. The final sound output level may be determined based on the value and the noise measurement value received by the noise measurement value receiving unit 23.
Further, the noise measurement value received by the noise measurement value receiving unit 23 may be stored for each time, and the initial value of the audio output level may be learned with a long-term time constant.

以上説明したように、本発明によれば、旅客案内装置が設置されたコンコースやホームの騒音レベルに応じて、案内放送の音声出力レベルを自動的に最適な値に調整することができるので、駅業務の負担を増大することなく、サービスの向上を図ることができるとともに、駅構内の安全性を高めることができる。   As described above, according to the present invention, the audio output level of the guidance broadcast can be automatically adjusted to an optimum value according to the noise level of the concourse or home where the passenger guidance device is installed.
