- the forward route CS1 and the return route CS2 of the registered route CS are as described above. Since the outbound path CS1 is a path toward the loading position LP1, the dump truck 20 traveling on the outbound path CS1 normally does not load a load. Since the return path CS2 is a path from the loading position LP1 to the soil discharge position DP1, the dump truck 20 traveling on the return path CS2 normally loads a load. For this reason, the size of the load differs between the dump truck 20 traveling on the forward path CS1 and the dump truck 20 traveling on the return path CS2.
- the dump truck 20 can determine whether it is traveling on the forward path CS1 or traveling on the return path CS2 according to the loading amount.

It is determined that the passage position WPa of the registered route CS does not match. Since the latter is the dump truck 20 that is loaded with the load despite going to the loading position LP1, the latter is the dump truck 20 that travels backward on the forward path CS1 or travels on a path different from the registered path CS. This is because it can be determined.

- the route determination unit 12a sets the midpoint of the distance Lmin between the passage position WP and the position information PIj as the corrected passage position WPn.
- the path determination unit 12a rewrites the uncorrected passage position WP described in the path-specific WP database 14WP of the management-side storage device 13 to the corrected passage position WPn. By doing so, the route-specific WP database 14WP is updated.
- step S110 the route determination unit 12a, as a third condition, the matching rate between the position information PI of the actual travel route CSr and the passing position WP of the registered route CS is equal to or greater than a predetermined threshold MCc, and all In the specific section SC, it is determined whether or not the passing positions at both ends of the specific section SC match the position information PI of the actual travel route CSr.

- the coincidence rate is a ratio of the passing position WP of the registered route CS that coincides with a plurality of pieces of position information PI included in the actual travel route CSr.

By doing in this way, the route determination unit 12a can determine whether or not the actual travel route CSr and the registered route CS coincide with each other in consideration of actual travel variations and measurement position errors. .
- the predetermined threshold MCc is, for example, about 0.8 to 0.9, but is not limited to this.
- the predetermined threshold value MCc may be changed depending on the state (for example, whether it is raining or dry) or the shape (the magnitude of a curvature, a gradient, or the like) on which the dump truck 20 travels. Depending on the condition of the road surface, even when traveling on the same track, the dump truck 20 may partially bypass the track. By doing so, the route determination unit 12a considers the actual track. Thus, it can be determined that the third condition is satisfied.

- the determination of whether or not the specific section positions SPt1 and SPt2 match the position information PI of the actual travel route CSr is the same as the determination of whether or not the passing position WP and the position information PI match.
- the route determination unit 12a determines that the actual travel route CSr is the same as the registered route CS. In this case, the route determination unit 12a updates the route information, specifically, the route information of the registered route CS stored in the management-side storage device 13 in step S111. For example, the route determination unit 12a updates at least one of the number of times, the time, and the operation information that the dump truck 20 has traveled on the registered route CS determined to be the same. As the number of times, 1 is added to the current number of times. By doing in this way, the frequency

- the route determination unit 12a does not update the number of times and the time that the dump truck 20 has traveled on the registered route CS determined to be the same as the actual travel route CSr. In this way, the registered route CS is updated with the latest information.
- step S112 When the route information of the registered route CS is updated, in step S112, at least of the number of travels, the travel time, and the operation information for each link of the registered route CS determined to be the same as the actual travel route CSr in step S110.

In step S114, the route determination unit 12a registers the position information of the unmatched position as a new earth removal position DP or loading position LP. Next, new registration of at least one of the soil removal position DP and the loading position LP will be described together with a case where new registration is not performed.
- FIG. 12 and FIG. 13 are diagrams for explaining a case where a new soil removal position DP is not registered. If the determination in step S104 is affirmative (Yes), the soil removal position DP and the loading position LP as the representative positions of the soil disposal site DPA0 are not newly registered.
- the soil removal position DP0 (travel start position SP1) of the registered route CS has already been described and registered in the LP / DP database 14RD and the registered route database 14CS of the management-side storage device 13 shown in FIG.
- the actual travel route CSr is within the range SPC1 having a predetermined radius RD centered on the already registered soil removal position DP0 (representative position of the soil disposal site DPA0), that is, within the soil disposal site DPA0.
- DP0 representation position of the soil disposal site DPA0
- the travel start position SPr of the actual travel route CSr matches the already registered soil discharge position DP0. Therefore, the travel start position SPr of the actual travel route CSr is not registered in the LP / DP database 14RD as the new soil removal position DPn.
- the travel start position SPr of the actual travel route CSr is a position where the load is lowered within a range SPC1 having a predetermined radius RD centered on the soil removal position DP0 (representative position of the soil disposal site DPA0).
- the area specifying unit 12c of the management-side processing device 12 illustrated in FIG. 2 corrects the already-registered soil removal position DP0 using the travel start position SPr of the actual travel route CSr. For example, the region specifying unit 12c sets the midpoint of both to the corrected soil removal position DP0n (travel start position SP1n). The area specifying unit 12c rewrites the uncorrected soil removal position DP0 described in the LP / DP database 14RD of the management-side storage device 13 to the corrected DP0n. By doing so, the path-specific LP / DP database 14RD is updated. In addition, in the earth removal field DPA1 shown in FIG. 7, it processes similarly to the earth removal field DPA0.
- the already registered soil removal position DP0 is corrected by using the travel start position SPr of the actual travel route CSr, the number of the travel start positions SPr of the actual travel route CSr is accumulated.
- the error of the soil position DP0 can be reduced.
- the earth removal sites DPA0 and DPA1 tend to gradually expand by lowering the load. For this reason, by correcting the soil discharge position DP0 using the travel start position SPr of the actual travel route CSr (the soil discharge position DPr of the actual travel route CSr in the soil removal field DPA1 shown in FIG. 7),
- the soil position DP0n can be reflected in the route specification. Next, a case where the loading position LP1 is not newly registered will be described.
- FIGS. 14 and 15 are diagrams for explaining a case where the loading position LP is not newly registered.
- the loading position LP1 of the registered route CS is already described and registered in the LP / DP database 14RD and the registered route database 14CS of the management storage device 13 shown in FIG.
- the loading position LPr of the actual travel route CSr exists in the range of the predetermined radius RL around the loading position LP1 that has already been registered, that is, in the loading field LPA1. .
- the loading position LPr of the actual travel route CSr matches the registered loading position LP1. Therefore, the loading position LPr of the actual travel route CSr is not registered in the LP / DP database 14RD as a new loading position LPn.
- the region specifying unit 12c corrects the registered loading position LP1 using the loading position LPr of the actual travel route CSr.
- the area specifying unit 12c corrects the registered loading position LP1 by changing the loading position LP1 to the loading position LPr of the actual travel route CSr.
- the loading position after correction is LP1n.
- a predetermined range around the corrected loading position LP1n becomes a new loading place LPA1n.
- whether the actual driving route LPr is within the predetermined range around the corrected loading position LP1n is determined as to whether the actual driving path LPr exists.
- a match between the loading position LPr of the route CSr and the registered loading position LP1n is determined.
- the corrected loading that is, the current loading The position LP1n can be reflected in the route specification.
- the loading position LP1 When the loading place LPA1 always moves along the vein, the loading position LP1 is regarded as the same loading place within a certain range and within a predetermined moving distance. Thus, it is preferable that a new loading position is not registered. In the example shown in FIG. 14, if the corrected loading position LP1n is within a predetermined movement distance within a certain period, it is regarded as the same loading field before and after correction. The loading position LP1n is not newly registered. For example, when the loading position LP1 moves more than the predetermined moving distance from the position registered first, the entire traveling distance of the traveling route at this time is excessively longer than the traveling distance when first registered. As a result, it is difficult to consider the same traveling route.
- the loading position LP1n When the corrected loading position LP1n is within the range of the predetermined movement distance, the loading position LP1 is considered to be the same loading place before and after the correction, and therefore the loading position LP1 moves along the vein. However, it can be avoided that it is difficult to regard the same traveling route as the entire traveling distance becomes longer. Further, if the corrected loading position LP1n is within a predetermined period and within a predetermined movement distance, it is considered that the same loading place before and after the correction is the old position information after the fixed period. This is for avoiding the coincidence determination based on the loading position LP1n.
- FIG. 16 and FIG. 17 are diagrams for explaining a case where the earth removal position DP is newly registered.
- the travel start position of the actual travel route CSr outside the soil removal field DPA0 that is, the range SPC1 having a predetermined radius RD centered on the already registered soil discharge position DP0 (travel start position SP1).
- the route determination unit 12a determines that the travel start position SPr of the actual travel route CSr does not coincide with the already registered soil removal position DP0.
- the area specifying unit 12c registers the position information and the like of the travel start position SPr on the actual travel route CSr in the LP / DP database 14RD as a new soil removal position DPn.
- the newly registered new soil removal position DPn is also used in the determination in step S103. That is, the route determination unit 12a starts traveling based on whether or not the traveling start position SPr of the actual traveling route CSr exists within a predetermined range SPC1n (excavation field DPA0n) having a predetermined radius RD centered on the soil discharging position DPn. A match between the position SPr and the soil removal position DPn is determined. Next, a case where the loading position LP is newly registered will be described.
- FIGS. 18 and 19 are diagrams for explaining a case where the loading position LP is newly registered.
- the loading position LPr of the actual travel route CSr exists outside the range of the predetermined radius RL centered on the loading position LP1 already registered, that is, the loading field LPA1.
- the route determination unit 12a determines that the loading position LPr of the actual travel route CSr does not coincide with the registered loading position LP1.
- the area specifying unit 12c registers the position information and the like of the loading position LPr on the actual travel route CSr in the LP / DP database 14RD as a new loading position LPn.
- the newly registered loading position LPn is also used in the determination in step S103. That is, the route determination unit 12a determines whether the loading position LPr and the loading position depend on whether or not the loading position LPr of the actual travel route CSr exists within a predetermined range LPC1n having a predetermined radius RL centered on the loading position LPn. A match with LPn is determined.
- the loading position LP corresponding to the second position of the registered route CS and the discharging position DP corresponding to the first position and the third position of the registered route CS are the new loading position LPn or the discharging position DPn is LP /
- the number increases every time it is registered in the DP database 14RD.
- the information on the loading position LP and the soil discharging position DP becomes older as time passes.
- the route determination unit 12a uses the one in which the period after the loading position LP and the soil discharging position DP are registered in the LP / DP database 14RD is within a predetermined period, The determination in step S103 is performed.
- the route determination unit 12a matches the soil removal position DP and the like of the registered route CS with the soil removal position DPr and the like of the actual travel route CSr corresponding to the state of the mine that changes from moment to moment. Therefore, the accuracy of the determination is improved.
- the predetermined period is not particularly limited, and can be, for example, several days to several weeks. The predetermined period may be different between the loading position LP and the soil discharging position DP. In this case, it is preferable that the loading position LP is shorter than the soil discharging position DP for a predetermined period. This is because the loading position LP has a tendency to move along the deposit or according to the work form, so that the position change is faster than the soil discharging position DP.
- step S115 the route determination unit 12a determines whether or not the position information PI of the actual travel route CSr matches the passing position WP of the registered route CS in the WP database 14WP for each route of the management-side storage device 13. It is executed for the passing position WP that has been described and has already been registered.

図3は、ダンプトラック20の構成を示す図である。ダンプトラック20は、積荷を積載して走行し、所望の場所でその積荷を排出する。ダンプトラック20は、車両本体21と、ベッセル22と、車輪23と、サスペンションシリンダー24と、回転センサ25と、サスペンション圧力センサ(以下、適宜圧力センサという)26と、アンテナ28Aが接続された車載無線通信装置27と、GPS用アンテナ28Bが接続された位置情報検出装置(本実施形態ではGPS受信機)29と、車載情報収集装置30と、を有する。なお、ダンプトラック20は、上記構成以外にも一般的な運搬機が備えている各種の機構及び機能を備えている。なお、本実施形態では、リジッド式のダンプトラック20を例として説明するが、ダンプトラック20は、車体を前部と後部に分割しそれらを自由関節で結合したアーティキュレート式ダンプトラックであってもよい。
図4は、車載情報収集装置及びその周辺機器を示す機能ブロック図である。ダンプトラック20が有する車載情報収集装置30は、車載記憶装置31と、車載無線通信装置27と、位置情報検出装置29とが接続されている。車載情報収集装置30には、さらに、状態取得装置が接続されている。車載情報収集装置30は、例えば、CPU(Central Processing Unit)とメモリとを組み合わせたコンピュータである。
図6は、本実施形態に係る経路特定処理の手順の一例を示すフローチャートである。本実施形態に係る経路特定処理を実行するにあたり、ステップS101において、管理側処理装置12、より具体的には経路判定部12aは、管理側無線通信装置18、図4に示す車載無線通信装置27及び位置情報検出装置29を介して、経路特定の対象であるダンプトラック20が走行した実走行経路CSrの位置情報PIを取得する。例えば、管理側処理装置12は、それぞれのダンプトラック20が走行した実走行経路CSrを、車載情報収集装置30を介して取得して管理側記憶装置13に記憶させておく。
本実施形態の第1変形例に係る鉱山機械の管理方法の処理手順を説明する。第1変形例に係る鉱山機械の管理方法は、図1に示す管理システム1、例えば、図2に示す管理装置10が実現する。第1変形例に係る鉱山機械の管理方法は、候補の経路を抽出してから、候補の経路毎に通過位置WPの一致判定を実行した後、走行距離の判定を実行する。具体的には、図6に示すフローチャートにおいて、管理側処理装置12は、ステップS105及びステップS106の後、ステップS106において肯定(Yes)のとき、ステップS109及びステップS110を実行する。ステップS110において肯定(Yes)のとき、次に、管理側処理装置12は、ステップS107及びステップS108を実行し、ステップS108において肯定(Yes)のとき、ステップS111を実行する。
本実施形態の第2変形例に係る鉱山機械の管理方法の処理手順を説明する。第2変形例に係る鉱山機械の管理方法は、図1に示す管理システム1、例えば、図2に示す管理装置10が実現する。第2変形例に係る鉱山機械の管理方法は、まず、既存の通過位置WPに対して一致判定をしてから、積込位置LP及び排土位置DPの一致判定及び経路の候補を検索する。その後に、候補コースに対して経路毎の通過位置WPの一致判定を実行する。
