Description

本発明は、工事関連車両、特にダンプトラックやアジテータ車等の大型車両が安全に通行するための工事関連車両の安全支援システムに関する。   The present invention relates to a safety support system for a construction-related vehicle for allowing a construction-related vehicle, particularly a large vehicle such as a dump truck or an agitator vehicle, to pass safely.

従来、車両の通行に際しては、目的地点を入力することにより、目的地点までの最適な経路を検索し、その検索した経路に沿って案内するようにしたカーナビゲーションシステムが広く使用されている。   2. Description of the Related Art Conventionally, when a vehicle passes, a car navigation system that searches for an optimum route to a destination point by inputting the destination point and guides along the searched route is widely used.

この種のカーナビゲーションシステムには、車両の種別、車両サイズ又は車両重量等に基づいて大型車両が通行可能な経路をリアルタイムに探索し、その経路に沿って車両を案内するようにしたものも知られている（例えば、特許文献１を参照）。   This type of car navigation system is also known in which a route through which a large vehicle can pass is searched in real time based on the type of vehicle, vehicle size or vehicle weight, and the vehicle is guided along the route. (For example, see Patent Document 1).

一方、ダンプトラックやアジテータ車等の大型の工事関連車両においては、工事期間中にコンクリートプラント等の資材供給基地と施工現場との間を何度も往復する場合、その経路は自ずと限定されるため、事前に調査を行い、工事関連車両の大きさや特性を考慮した上で適切な経路を選定しておき、その選定された一定の経路を使用するのが一般的である。   On the other hand, in large construction-related vehicles such as dump trucks and agitator vehicles, the route is naturally limited when reciprocating between the material supply base such as a concrete plant and the construction site many times during the construction period. It is common to conduct a survey in advance, select an appropriate route in consideration of the size and characteristics of the construction-related vehicle, and use the selected fixed route.

また、工事関連車両の通行に際しては、選定された経路上の危険個所や学校等の施設の有無を事前の調査に基づいて把握しておき、運転者に注意喚起することが安全管理上重要である。   In addition, it is important for safety management to understand the presence or absence of dangerous places and facilities such as schools on the selected route based on prior surveys when passing construction-related vehicles. is there.

尚、従来では、選定された経路上に危険個所や学校等の施設が存在する場合、その周辺に至ると運転者に注意を促すようにした工事車両の安全システムも開発されている（例えば、特許文献２を参照）。   Conventionally, when a facility such as a dangerous place or a school exists on a selected route, a safety system for a construction vehicle has been developed so as to alert the driver when it reaches the vicinity (for example, (See Patent Document 2).

特開平１１ −００２５３５号公報Japanese Patent Laid-Open No. 11-002535 特開２０１２−０２６９１９号公報JP 2012-026919 A

しかしながら、上述の如き従来の安全支援システムでは、事前の経路検索において距離や時間及び料金に対して最適な経路を検索することは可能であるが、安全について最適な経路を検索できないという問題があった。   However, in the conventional safety support system as described above, it is possible to search for an optimum route for distance, time, and fee in advance route search, but there is a problem that an optimum route for safety cannot be searched. It was.

尚、従来の安全支援システムでは、選定した道路が使用できない事態を想定し、複数の通行経路を選定しておくことが望まれるが、この種の安全支援システムは、通行中に事故多発地点等の危険個所に近づいた際に初めて、その危険個所に関する注意喚起が音声等で発せられるものであり、事前の経路検索に危険個所が反映されないため、安全な最適な経路を選定できないという問題があった。   In addition, in the conventional safety support system, it is desirable to select a plurality of traffic routes assuming that the selected road cannot be used. For the first time when approaching a dangerous location, a warning is issued by voice, etc., and the risk location is not reflected in the prior route search, so there is a problem that it is not possible to select a safe and optimal route. It was.

また、従来の安全支援システムでは、学校等の要配慮施設が地図上に表示されるだけで、個別に特定しなければ通行時に注意喚起されることがなく、また、事前の経路検索にも反映されないという問題があった。   In addition, with the conventional safety support system, only the facilities that require consideration such as schools are displayed on the map, and if you do not specify them individually, you will not be alerted when passing, and will also be reflected in the route search in advance. There was a problem of not being.

更に、使用する通行経路は、事前調査に基づいて選定するため、最新の道路状況が反映されず、経路上に存在する注意喚起すべき個所が見落とされるおそれがあった。   Furthermore, since the traffic route to be used is selected based on a preliminary survey, the latest road conditions are not reflected, and there is a possibility that a location on the route that should be alerted may be overlooked.

一方、工事関連車両の使用経路は、自ずと限定されている場合があるにも関わらず、各車両にカーナビゲーションシステムを導入するとなると費用負担が大きいという問題があった。   On the other hand, there is a problem that the cost burden is large when a car navigation system is introduced to each vehicle, although the use route of the construction-related vehicle is naturally limited.

そこで、本発明は、このような従来の問題に鑑み、工事関連車両の通行に際し、最新の情報に基づいた安全な通行経路の提示並びに危険個所及び学校等の要配慮施設に関する注意喚起を事前に行える工事関連車両の安全支援システムの提供を目的としてなされたものである。   Therefore, in view of such conventional problems, the present invention presents in advance a safe passage route based on the latest information and alerts regarding dangerous places and important facilities such as schools, etc. when passing construction-related vehicles.

Various arithmetic processes based on the program stored in the computer can be performed.

即ち、この制御部１３は、経路検索手段、特定危険個所検出手段、要配慮区域検出手段及び事前確認画像生成手段を構成している。   That is, the control unit 13 constitutes a route search unit, a specific danger point detection unit, a sensitive area detection unit, and a prior confirmation image generation unit.

次に、この安全支援システム１０による具体的な支援手順について説明する。   Next, a specific support procedure by the safety support system 10 will be described.

先ず、工事の施工計画に基づいて使用する車種（大きさ及び種別）、出発地点Ａ及び目的地点Ｂをタッチパネルやキーボード等の操作手段１１によって入力する。   First, the vehicle type (size and type), the starting point A, and the destination point B to be used based on the construction plan are input by operating means 11 such as a touch panel or a keyboard.

制御部１３は、入力された車体の情報（以下、車体情報という）を読み出し、その車体情報と、出発地点Ａに近いノードから順次そのノードから分岐する各リンクの固有情報と車体情報とを比較し、各リンクより工事関連車両が通行可能なリンクを選択することにより、最適な経路２０を検索し（経路検索処理）、検索された経路２０を通行経路２０に設定するとともに記憶する。   The control unit 13 reads the input vehicle body information (hereinafter referred to as vehicle body information), and compares the vehicle body information with the vehicle body information and the specific information of each link that branches from the node in sequence from the node close to the departure point A. Then, by selecting a link through which the construction-related vehicle can pass from each link, the optimum route 20 is searched (route search processing), and the searched route 20 is set as the passing route 20 and stored.

次に、制御部１３は、データ記憶部１２に記憶された危険個所情報を読み出し、設定された経路２０上の座標が危険個所情報の座標と一致するかを判定し、経路２０上の位置座標と一致する危険個所を特定危険個所ｄ１〜ｄ５として検出し、その位置座標とともに記憶する（危険個所検出処理）。   Next, the control unit 13 reads out the dangerous location information stored in the data storage unit 12, determines whether the set coordinates on the route 20 coincide with the coordinates of the dangerous location information, and the position coordinates on the route 20. Are detected as specific dangerous locations d1 to d5 and stored together with their position coordinates (dangerous location detection processing).

更に、制御部１３は、データ記憶部１２に記憶された要配慮施設情報を読み出し、その各要配慮施設ｓ１の座標を中心とした一定範囲内に経路２０上の座標が含まれるかを判定し、座標が当該一定範囲内に含まれる経路上の区域を要配慮区域３ａ〜３ｂとして検出し、その要配慮区域３ａ〜３ｂに含まれる位置座標とともに記憶する（要配慮施設検出処理）。   Further, the control unit 13 reads out the facility information that is required to be stored in the data storage unit 12, and determines whether the coordinates on the route 20 are included in a certain range centered on the coordinates of the facility s1 that are required. The areas on the route whose coordinates are included in the certain range are detected as the consideration areas 3a to 3b, and stored together with the position coordinates included in the consideration areas 3a to 3b (consideration facility detection process).

そして、制御部１３は、検出された特定危険個所ｄ１〜ｄ５及び要配慮区域３ａ〜３ｂに対しその道順に即して固有の符号（本実施例では番号）を付与する。   And the control part 13 assign | provides a specific code | symbol (a number in a present Example) according to the route with respect to the detected specific danger locations d1-d5 and the consideration required areas 3a-3b.

次に、制御部１３は、経路２０、特定危険個所ｄ１〜ｄ５及び要配慮区域３ａ〜３ｂを表示した地図画像データを生成するとともに、検知された全ての特定危険個所ｄ１〜ｄ５及び要配慮区域３ａ〜３ｂの固有情報を一覧化した一覧表画像データを生成する。   Next, the control unit 13 generates map image data displaying the route 20, the specific danger locations d1 to d5 and the areas to be considered 3a to 3b, and all the detected specific danger locations d1 to d5 and the areas to be considered are required. List image data that lists the unique information of 3a to 3b is generated.

更に、制御部１３は、地図画像データと一覧表画像データとを合成した事前確認画像データを生成し（画像生成処理）、その画像信号を表示手段１４に出力し、例えば、図２に示すように、表示画面範囲の上半部に地図画像２１が配置され、下半部に一覧表２２が配置された事前確認画像２３を表示手段１４に表示させる。   Further, the control unit 13 generates prior confirmation image data obtained by combining the map image data and the list image data (image generation processing), and outputs the image signal to the display unit 14, for example, as shown in FIG. In addition, the display unit 14 displays a prior confirmation image 23 in which the map image 21 is arranged in the upper half of the display screen range and the list 22 is arranged in the lower half.

また、制御部１３は、必要に応じて又は選択により事前確認画像２３をプリンターより紙媒体に印刷する。   Further, the control unit 13 prints the preconfirmation image 23 on a paper medium from the printer as necessary or by selection.

そして、運転者は、通行業務開始前に出力された事前確認画像２３を視認することによって、通行中に注意すべき危険個所ｄ１〜ｄ５及び要配慮区域３ａ〜３ｂを地図と文字の両方で事前に確認し、把握することができる。   Then, the driver visually recognizes the prior confirmation image 23 output before the start of the traffic operation, so that the dangerous locations d1 to d5 and the areas to be considered 3a to 3b to be noted during the traffic in advance on both the map and the characters. You can check and grasp.

次に、必要に応じて、タブレットＰＣ等の携帯端末を工事関連車両に搭載し、通行を開始する。   Next, if necessary, a portable terminal such as a tablet PC is mounted on the construction-related vehicle, and traffic is started.

その際、携帯端末にＧＮＳＳ等の位置検知手段３０を備えていれば、随時検知した工事関連車両の位置情報を制御部１３に出力し、制御部１３は、その位置情報を基に地図画像２１上に工事関連車両の現在位置を表示させる。   At that time, if the mobile terminal is provided with position detection means 30 such as GNSS, the position information of the construction-related vehicle detected at any time is output to the control unit 13, and the control unit 13 maps the map image 21 based on the position information. The current position of the construction-related vehicle is displayed on the top.

よって、運転者は、地図画像２１上の工事関連車両の位置をリアルタイムに表示画像上で確認することができる。   Therefore, the driver can confirm the position of the construction-related vehicle on the map image 21 on the display image in real time.

また、制御部１３は、工事関連車両の現在位置座標が特定危険個所ｄ１〜ｄ５の座標及び要配慮区域３ａ〜３ｂから一定範囲内に位置するかを判定し、一定範囲に含まれると判定された場合には、スピーカ又は警告灯等の通知手段３１を作動させ、運転者に対し特定危険個所の直前又は要配慮区域に進入する直前に注意を促す。   In addition, the control unit 13 determines whether the current position coordinates of the construction-related vehicle are located within a certain range from the coordinates of the specific danger locations d1 to d5 and the areas to be considered 3a to 3b, and is determined to be included in the certain range. In such a case, the notification means 31 such as a speaker or a warning light is operated to alert the driver immediately before the specific danger point or just before entering the area requiring consideration.

更に、制御部１３は、工事関連車両の現在位置座標が要配慮区域３ａ〜３ｂから一定範囲内に位置するかを判定し、要配慮区域から離脱したと判断された場合には、要配慮区域３ａ〜３ｂを出た直後に通知手段３１を作動させ、運転者に通知するようにしてもよい。   Further, the control unit 13 determines whether or not the current position coordinates of the construction-related vehicle are within a certain range from the areas to be considered 3a to 3b. Immediately after exiting 3a to 3b, the notification means 31 may be operated to notify the driver.

尚、上述の実施例では、要配慮施設として学校（幼稚園、保育園、小中学校、高等学校）を例に挙げたが、要配慮施設はこれだけに限定されず、例えば、病院、養護老人ホーム、児童公園等を含めてもよい。   In the above-described embodiments, schools (kindergarten, nursery school, elementary and junior high school, high school) have been taken as examples of facilities requiring consideration. However, facilities requiring consideration are not limited to these, for example, hospitals, nursing homes, children You may include parks.

また、事前確認画像２３の態様は、上述の実施例に限定されず、経路２０、特定危険個所ｄ１〜ｄ５及び要配慮区域３ａ〜３ｂの全てが地図画像２１と一覧表とに網羅されていればよい。   Further, the aspect of the prior confirmation image 23 is not limited to the above-described embodiment, and the route 20, the specific danger locations d1 to d5, and the areas to be considered 3a to 3b are all covered by the map image 21 and the list. That's fine.

また、上述の実施例では、主にタブレットＰＣ等の携帯端末により構成された例について説明したが、この安全支援システムの態様は、これに限定されず、例えば、パソコン等からなるシステム親機と、システム本体とインターネット回線や無線回線を介して接続されたシステム子機とをもって構成してもよい。   Further, in the above-described embodiment, an example mainly configured by a portable terminal such as a tablet PC has been described.
