Description

本発明は、ワイヤーハーネス経路設計方法に関する。 The present invention relates to a wire harness route designing method.

近年、ワイヤーハーネスの経路の設計を容易にするためのハーネス配線経路算出方法が提案されている（例えば、特許文献１参照）。 In recent years, a harness wiring route calculation method for facilitating the design of a route of a wire harness has been proposed (for example, refer to Patent Document 1).

このハーネス配線経路算出方法は、装置の３次元モデルとハーネス条件を基に設定したハーネス配線経路探索空間を分割して複数の格子点を算出し、配線経路始点を起点に設定した配線経路禁止領域以外の格子点の中から経路終点の方向に一番近い格子点を順次抽出し、抽出した格子点より算出する曲率半径がハーネス最小曲率半径より大きい場合、前記抽出した格子点を配線経路格子点として順次選択するものである。 This harness wiring route calculation method divides a harness wiring route search space set based on a three-dimensional model of a device and a harness condition to calculate a plurality of grid points, and sets a wiring route start point as a starting point of a wiring route prohibited area. If the radius of curvature calculated from the extracted grid points is larger than the harness minimum curvature radius, the extracted grid points are the wiring path grid points. Are sequentially selected.

しかし、従来のハーネス配線経路算出方法は、適用する装置を３次元モデル化したハーネス配線経路探索空間全体に対して複数の格子点を算出し、これらの格子点を基に配線経路を算出しているため、複雑な演算を必要し、鉄道車両のように大きな構造体には適さない。 However, in the conventional harness wiring route calculation method, a plurality of grid points are calculated for the entire harness wiring route search space in which a device to be applied is three-dimensionally modeled, and a wiring route is calculated based on these grid points. Therefore, it requires complicated calculations and is not suitable for large structures such as railway cars.

また、鉄道車両のように大きな構造体の場合、ワイヤーハーネスの経路を設計するのに２次元の図面上で主要なワイヤーハーネスの経路設計を行い、さらに現車にワイヤーハーネスを直接合わせて最適な経路となるように試行錯誤を重ねてワイヤーハーネスの経路を決定するため、ワイヤーハーネスの経路の設計に長期間を要していた。 In the case of a large structure such as a railroad car, the main wire harness route is designed on a two-dimensional drawing to design the route of the wire harness, and the wire harness is directly fitted to the actual vehicle to optimize the design. It takes a long time to design the route of the wire harness because the route of the wire harness is determined through trial and error so that the route becomes the route.

そこで、本発明の目的は、ワイヤーハーネスの経路の設計を現車にワイヤーハーネスを直接合わせて最適な経路を調整する作業を必要とせずに短期間に行うことができるワイヤーハーネス経路設計方法を提供することにある。 Therefore, an object of the present invention is to provide a wire harness route designing method capable of designing a route of a wire harness in a short period of time without requiring work for directly adjusting a wire harness to a current vehicle to adjust an optimal route.

（実施の形態の動作）
次に、本実施の形態の動作の一例を図２〜図６を参照して説明する。(Operation of the embodiment)
Next, an example of the operation of this embodiment will be described with reference to FIGS.

（１）３次元ＣＡＤデータ及びハーネス情報の受付
受付手段２０は、例えば入力部４のディスクドライブから、鉄道車両について筐体、筐体の内部構造、及び複数の配線部材の形状情報と位置情報を含む３次元ＣＡＤデータ３１、及び経路ごとに定められた複数のワイヤ−ハーネスを構成する電線の種類及び接続先を含むハーネス情報３２を受け付ける。受付手段２０は、受け付けた３次元ＣＡＤデータ３１及びハーネス情報３２を記憶部３に記憶する。(1) Reception of three-dimensional CAD data and harness information The reception means 20 receives, for example, the disk drive of the input unit 4 from the disk drive of the input unit 4 for the railcar, the housing, the internal structure of the housing, and the shape information and position information of a plurality of wiring members. The three-dimensional CAD data 31 including the data and the harness information 32 including the types and connection destinations of the electric wires forming the plurality of wire-harnesses defined for each route are received. The reception unit 20 stores the received three-dimensional CAD data 31 and harness information 32 in the storage unit 3.

（２）３次元仮想空間の表示
表示手段２１は、筐体、筐体の内部構造、及び複数の配線部材１１（図３参照）を３次元ＣＡＤデータ３１に基づいて３次元仮想空間１０（図２参照）に配置し、それを表示部５の画面に表示する。(2) Display of three-dimensional virtual space The display means 21 displays the three-dimensional virtual space 10 (see FIG. 3) on the housing, the internal structure of the housing, and the plurality of wiring members 11 (see FIG. 3) based on the three-dimensional CAD data 31. 2), and displays it on the screen of the display unit 5.

（３）仮想経路空間の形成
仮想経路空間形成手段２２は、３次元仮想空間１０に複数の経路に沿って表示された複数の配線部材１１の近傍を通るようにハーネス情報３２に基づいて仮想経路空間１０（図２参照）を形成する。なお、この処理は、ハーネス情報３２に基づいて設計者が行ってもよい。(3) Formation of Virtual Route Space The virtual route space forming means 22 passes through the vicinity of the plurality of wiring members 11 displayed along the plurality of routes in the three-dimensional virtual space 10 based on the harness information 32. A space 10 (see FIG. 2) is formed. The designer may perform this process based on the harness information 32.

図２は、仮想経路空間形成手段２２が形成した仮想経路空間の一例を示す斜視図である。なお、図２では、配線部材の図示を省略している。図３は、図２のＡ部拡大図である。図４Ａは、図３のＢ−Ｂ線断面図、図４Ｂは、複数のワイヤーハーネスを布線するのに必要な断面積を説明するための断面図である。 FIG. 2 is a perspective view showing an example of the virtual route space formed by the virtual route space forming means 22. Note that the wiring member is not shown in FIG. 2. FIG. 3 is an enlarged view of part A of FIG. FIG. 4A is a cross-sectional view taken along the line BB of FIG. 3, and FIG. 4B is a cross-sectional view for explaining a cross-sectional area required for wiring a plurality of wire harnesses.

仮想経路空間形成手段２２は、図２、図３及び図４Ａに示すように、配線部材１１の近傍に例えば断面矩形状の仮想経路空間１２を形成する。具体的には、仮想経路空間形成手段２２は、図４Ｂに示すように、当該仮想経路空間１２の断面積Ｓａが当該複数のワイヤーハーネス１３０全体を結束部材１３２で緩く束ねたときに当該複数のワイヤーハーネスを布線するのに必要な断面積Ｓｂ以上（Ｓａ≧Ｓｂ）となるように仮想経路空間１２を形成する。なお、この処理は設計者が行ってもよい。 As shown in FIGS. 2, 3, and 4A, the virtual path space forming means 22 forms the virtual path space 12 having a rectangular cross section, for example, in the vicinity of the wiring member 11. Specifically, as shown in FIG. 4B, the virtual route space forming unit 22 has a plurality of cross-sectional areas Sa of the virtual route space 12 when the entire plurality of wire harnesses 130 are loosely bound by the binding member 132. The virtual route space 12 is formed so as to have a cross-sectional area Sb or more (Sa≧Sb) required for wiring the wire harness. The designer may perform this process.

配線部材１１は、帯板状の鋼板の長手方向の両端部を仮想経路空間１２と反対側に曲げて形成されている。配線部材１１の長手方向は仮想経路空間１２の長手方向に一致させた方が好ましいが、必ずしも一致させなくてもよい。 The wiring member 11 is formed by bending both ends of a strip-shaped steel plate in the longitudinal direction to the side opposite to the virtual path space 12. It is preferable that the longitudinal direction of the wiring member 11 coincides with the longitudinal direction of the virtual path space 12, but it does not always have to coincide.

FIG. 5 is a diagram showing an example of a virtual ring arranged on a virtual cross section of the virtual route space 12. FIG. 6 is a perspective view for explaining the work of wiring the wire harness between two virtual cross sections.

判定手段２３は、設計者の入力部４の操作により、複数の経路のうち選択された１つの経路に対応する複数のワイヤーハーネスの最適なハーネス経路を、設計者の入力部４の操作により、当該仮想経路空間に対して探索することで、当該複数のワイヤーハーネスを当該仮想経路空間に布線することが可能かどうかを判定する。 The determining unit 23 determines the optimum harness route of the plurality of wire harnesses corresponding to the selected one route among the plurality of routes by the operation of the input unit 4 by the designer. By searching the virtual route space, it is determined whether the plurality of wire harnesses can be wired in the virtual route space.

判定手段２３は、設計者の入力部４の操作により、当該複数のワイヤーハーネスを電線の種類ごとにワイヤーハーネス１３０、１３１（図６参照）に分け、図５に示すように、当該仮想経路空間１２の仮想断面１２０ａ、１２０ｂ上にワイヤーハーネス１３０、１３１に対応する大きさの仮想リング１２１を配置し、図６に示すように、仮想リング１２１にワイヤーハーネス１３０、１３１を布線することで、当該複数のワイヤーハーネスを当該仮想経路空間に布線することが可能かどうかを判定する。 The determination unit 23 divides the plurality of wire harnesses into wire harnesses 130 and 131 (see FIG. 6) for each type of electric wire by the operation of the input unit 4 by the designer, and as shown in FIG. By arranging a virtual ring 121 having a size corresponding to the wire harnesses 130 and 131 on the virtual cross sections 120a and 120b of 12 and laying the wire harnesses 130 and 131 on the virtual ring 121, as shown in FIG. It is determined whether the plurality of wire harnesses can be wired in the virtual route space.

具体的には、設計者は、図６に示すように、２つの仮想断面１２０ａ、１２０ｂ上に形成された仮想リング１２１を選択することで、仮想リング１２１の中心の位置情報、すなわちハーネス通過点が設定されたことになる。次に、設計者は、選択した仮想リング１２１に対応するワイヤーハーネス１３０、１３１の図示を指示すると、２つの仮想断面１２０ａ、１２０ｂ間に対応するワイヤーハーネス１３０、１３１が表示される。そして設計者は、ワイヤーハーネス１３０、１３１を布線して問題がないかどうかを確認する。確認する方法としては、例えば、ＡＣ用のワイヤーハーネス１３０、１３１とシールド用のワイヤーハーネス１３０、１３１を所定の距離離すことができるかを確認する。 Specifically, the designer selects the virtual ring 121 formed on the two virtual cross sections 120a and 120b, as shown in FIG. 6, to thereby obtain the position information of the center of the virtual ring 121, that is, the harness passage point. Has been set. Next, when the designer instructs the wire harnesses 130 and 131 corresponding to the selected virtual ring 121 to be illustrated, the wire harnesses 130 and 131 corresponding to the two virtual cross sections 120a and 120b are displayed. Then, the designer arranges the wire harnesses 130 and 131 and confirms whether there is any problem. As a confirmation method, for example, it is confirmed whether the AC wire harnesses 130 and 131 and the shield wire harnesses 130 and 131 can be separated by a predetermined distance.

（５）上記（４）の判定結果が否定的の場合
上記（４）の判定で当該複数のワイヤーハーネスを当該仮想経路空間に布線することが可能でないと判定したとき、例えば、次の３つのいずれかの修正処理を行う。
（ｉ）ハーネス経路を変更する。
（ii）当該仮想経路空間の断面を拡大する。
なお、上記以外に他の修正処理を行ってもよい。(5) When the determination result of (4) is negative When it is determined in the determination of (4) that the plurality of wire harnesses cannot be wired in the virtual route space, for example, the following 3 Do any one of the corrections.
(I) Change the harness route.
(Ii) Enlarge the cross section of the virtual path space.
In addition to the above, other correction processing may be performed.

その後は、上記（４）、（５）を繰り返してワイヤーハーネスの経路を設計する。設計が終わると、制御部２は、仮想経路空間情報３３及びワイヤーハーネス経路情報３４を更新する。仮想経路空間情報３３及びワイヤーハーネス経路情報３４は、例えば、ワイヤーハーネスの配線作業の際に携帯端末装置に表示して配線作業のガイドに利用される。 After that, the above (4) and (5) are repeated to design the route of the wire harness. When the design is finished, the control unit 2 updates the virtual route space information 33 and the wire harness route information 34. The virtual route space information 33 and the wire harness route information 34 are displayed on the mobile terminal device during the wiring work of the wire harness and used as a guide for the wiring work, for example.

（実施の形態の作用、効果）
本実施の形態によれば、以下の作用、効果を奏する。
（ａ）仮想経路空間１２の断面積Ｓａが対応する複数のワイヤーハーネス１３０を通すのに必要な断面積Ｓｂ以上となるように仮想経路空間１２を形成し、この仮想経路空間１２を基準に最適なハーネス経路の探索を行っているので、ワイヤーハーネスの経路の設計を短期間に行うことができる。例えば、従来５日を要していたものが２日に短縮されている。
（ｂ）新型車両のように現車が存在しない場合でも、３次元空間上でワイヤーハーネスの経路のシミュレーションを行えるので、ワイヤーハーネス経路の設計が可能になる。
（ｃ）自動車と比べて鉄道車両は、多くが床下配線のため、現車合わせによる加工作業が多いが、本実施の形態によれば、現車合わせによる加工作業を少なくすることができ、ワイヤーハーネスの設計が極めて容易になる。(Operation and effect of the embodiment)
According to this embodiment, the following actions and effects are exhibited.
(A) The virtual path space 12 is formed so that the cross-sectional area Sa of the virtual path space 12 is equal to or larger than the cross-sectional area Sb required to pass the corresponding plurality of wire harnesses 130, and the virtual path space 12 is optimal with reference to this virtual path space 12. Since it is searching for various harness routes, it is possible to design the route of the wire harness in a short time. For example, what used to take 5 days has been shortened to 2 days.
(B) Even when there is no current vehicle such as a new model vehicle, the route of the wire harness can be simulated in the three-dimensional space, so that the route of the wire harness can be designed.
(C) Compared to automobiles, many railroad cars are underfloor wiring, and therefore, there are many processing works by matching the current car. However, according to the present embodiment, the working works by matching the current car can be reduced, and the wirework can be reduced. The harness design becomes extremely easy.
