　図２は、走行車システムの機能構成などを模式的に示すブロック図である。 FIG. 2 is a block diagram schematically showing the functional configuration of the traveling vehicle system.
　これらの図に示すように、走行車システム１００は、経路１１０に沿って走行する走行車１０１と、充電装置１０２と、中央制御装置１０３とを備えている。 As shown in these drawings, the traveling vehicle system 100 includes a traveling vehicle 101 that travels along a route 110, a charging device 102, and a central control device 103.
　経路１１０は、走行車１０１が走行する進路を決定するものである。具体的には経路１１０は、床面や天井などに敷設されるレールや、走行車１０１を誘導するために床面に断続的に設けられる磁石などによって決定される軌道である。また、走行車１０１がレーザー光線による三角測量や電波などの位置認識システムを備え自立的に走行する場合、経路１１０は、具体的なものでは無くプログラムなどによって仮想的に設けられるものとなる。なお、図１中では経路１１０を単純な形状として記載しているが、実際に経路１１０は、工場建屋や生産設備の配置などによって複雑な形状となる。また、分岐部を備えて他の経路と一部分を共有するような場合もある。 The route 110 determines a course along which the traveling vehicle 101 travels. Specifically, the route 110 is a track determined by a rail laid on the floor surface, ceiling, or the like, or a magnet provided intermittently on the floor surface to guide the traveling vehicle 101. Further, when the traveling vehicle 101 travels autonomously with a position recognition system such as triangulation using a laser beam or radio waves, the route 110 is virtually provided by a program or the like, not a specific one. In FIG. 1, the route 110 is described as a simple shape, but actually the route 110 has a complicated shape depending on the layout of a factory building or production equipment. In some cases, a branch portion is provided and a part of the route is shared with another route.
　走行車１０１は、蓄電装置１１１を備え、蓄電装置１１１に蓄えられた電力に基づき自走することができる車両である。本実施の形態の場合、走行車システム１００は、経路１１０に沿って複数箇所にステーション１０４を備えており、走行車１０１は、ステーション１０４から渡された荷物を他のステーション１０４まで搬送する搬送車である。また、走行車１０１は、蓄電装置１１１に蓄えられた電力に基づき稼働し、ステーション１０４との間で荷物を移載する移載装置（図示せず）を備えていてもよい。 The traveling vehicle 101 includes a power storage device 111 and is a vehicle capable of self-propelling based on electric power stored in the power storage device 111. In the case of the present embodiment, the traveling vehicle system 100 includes stations 104 at a plurality of locations along the route 110, and the traveling vehicle 101 transports a package delivered from the station 104 to another station 104. It is. In addition, the traveling vehicle 101 may be provided with a transfer device (not shown) that operates based on the electric power stored in the power storage device 111 and transfers loads to and from the station 104.
　また、走行車１０１は、蓄電装置１１１の蓄電状態に関する情報である蓄電情報を作成し、当該蓄電情報について中央制御装置１０３と通信を行う蓄電情報通知部１１２を備えている。 In addition, the traveling vehicle 101 includes a power storage information notification unit 112 that creates power storage information that is information related to the power storage state of the power storage device 111 and communicates with the central control device 103 regarding the power storage information.
　なお、走行車１０１は、経路１１０上のどの部分で停止、または、走行しているか、例えば、充電領域１２１（後述）やどのステーション１０４で停止しているかや、どのステーション１０４とどのステーション１０４との間を走行しているかを認識することができ、また、停止位置や走行位置を示す情報や荷物を保持しているか否かの情報を中央制御装置１０３に送信し、どのステーション１０４で荷物を受け取りどのステーション１０４で荷物を渡すかを示す搬送計画などを受信することができるものとなっている。 It should be noted that the traveling vehicle 101 is stopped or traveling on the route 110, for example, the charging area 121 (described later), which station 104 is stopped, which station 104 and which station 104 The information indicating the stop position and the traveling position and the information indicating whether or not the baggage is held are transmitted to the central controller 103, and at which station 104 the baggage is It is possible to receive a transportation plan or the like indicating which station 104 receives the package.
　蓄電情報通知部１１２は、例えば、蓄電装置１１１の蓄電状態を蓄電装置１１１の出力電圧により把握し、出力電圧が第一閾値以上の場合、蓄電状態が満状態であるとして満状態を示す蓄電情報を送信し、出力電圧が第一閾値よりも低い第二閾値以下の場合、蓄電状態が欠乏状態であるとして欠乏状態を示す蓄電情報を送信する処理部である。 For example, the power storage information notifying unit 112 grasps the power storage state of the power storage device 111 from the output voltage of the power storage device 111, and when the output voltage is equal to or higher than the first threshold, the power storage information indicating the full state as the power storage state is full. When the output voltage is equal to or lower than the second threshold value, which is lower than the first threshold value, the storage unit transmits the storage information indicating the shortage state as the shortage state.
　なお、図中において蓄電情報通知部１１２は、無線により通信するものとして描かれているが、有線により通信するものでもかまわない。また、蓄電情報通知部１１２は、閾値判断等をすることなく、蓄電装置１１１の蓄電状態そのものを示す情報（例えば出力電圧）を通信するものでもかまわない。 In addition, although the electrical storage information notification part 112 is drawn as what communicates by radio | wireless in the figure, you may communicate by a wire communication. Further, the power storage information notification unit 112 may communicate information (for example, output voltage) indicating the power storage state of the power storage device 111 without making a threshold determination or the like.
　蓄電装置１１１は、リチウムイオン電池やリチウムイオンキャパシタ等の二次電池や、これら二次電池を制御する回路や、充電装置１０２から供給される電力を受電する受電コア、供給された交流の電力を直流に変換する装置などを備えた装置である。 The power storage device 111 includes a secondary battery such as a lithium ion battery or a lithium ion capacitor, a circuit that controls the secondary battery, a power receiving core that receives power supplied from the charging device 102, and supplied AC power. It is a device provided with a device for converting to direct current.
　充電装置１０２は、走行車１０１に搭載された蓄電装置１１１に非接触で充電することができる装置であり、経路１１０の一部に沿って設けられる給電線１２２と給電線１２２に交流電流を供給する給電装置１２３とを備えている。本実施の形態の場合、給電線１２２としては、充電領域１２１において往道用の導線（例えばリッツ線）と復道用の導線とが平行になるように配置し、前記往道用の電線と前記復道用の電線との端部どうしを電気的に接続し、電流の導通経路として１本の導通経路をＵ字状に曲げた状態のものが用いられる。また、給電線１２２は、図３に示すように、充電領域１２１内に停車している複数台の走行車１０１の各蓄電装置１１１を一度に充電できる長さを備えている。 The charging device 102 is a device that can charge the power storage device 111 mounted on the traveling vehicle 101 in a non-contact manner, and supplies an alternating current to a power supply line 122 and a power supply line 122 provided along a part of the path 110. Power supply device 123. In the case of the present embodiment, as the power supply line 122, in the charging region 121, a forward lead wire (for example, a litz wire) and a return lead wire are arranged in parallel, The end of the return path wire is electrically connected to each other, and a current conduction path in which one conduction path is bent in a U shape is used. In addition, as shown in FIG. 3, the power supply line 122 has a length capable of charging each power storage device 111 of the plurality of traveling vehicles 101 stopped in the charging area 121 at a time.
　なお、充電装置１０２は、走行車システム１００が備える全ての走行車１０１に対して充電できるものが好ましい。この場合、一つの充電領域１２１に全ての走行車１０１を配置し、走行車１０１の列の長さと同等、または、ほぼ同等の長さの倍の長さの給電線１２２を充電装置１０２が備えてもよく、また、経路１１０に沿って複数の充電領域１２１が分散状態で配置され、それぞれの充電領域１２１に充電装置１０２を配置してもかまわない。 The charging device 102 is preferably one that can charge all the traveling vehicles 101 included in the traveling vehicle system 100. In this case, all the traveling vehicles 101 are arranged in one charging area 121, and the charging device 102 includes a power supply line 122 having a length equal to or almost double the length of the row of traveling vehicles 101. Alternatively, a plurality of charging areas 121 may be arranged in a distributed state along the path 110, and the charging device 102 may be arranged in each charging area 121.
　また、充電装置１０２は、充電領域１２１を通過する走行車１０１に搭載される蓄電装置１１１に対し充電することができるものとなっている。具体的に例えば、荷物を搭載した走行車１０１が通常走行する速度で充電領域１２１を通過する際に、少なくとも次の充電領域１２１（同じ充電領域１２１もあり得る）に到達するまでに走行車１０１に必要な電力（走行ばかりで無く、荷物を移載する電力も含む）を充電することができる長さの給電線１２２を充電装置１０２は備えている。 Moreover, the charging device 102 can charge the power storage device 111 mounted on the traveling vehicle 101 that passes through the charging area 121. Specifically, for example, when the traveling vehicle 101 loaded with luggage passes through the charging area 121 at a normal traveling speed, the traveling vehicle 101 reaches at least the next charging area 121 (the same charging area 121 may also be present). The charging device 102 is provided with a power supply line 122 having a length capable of charging the electric power necessary for the vehicle (including not only traveling but also electric power for transferring a load).
　中央制御装置１０３は、走行車システム１００の制御を司るコンピュータなどであって、充電指示部１３１と、省電力制御部１３２とを備えている。本実施の形態の場合、中央制御装置１０３はさらに、走行監視部１３３と通信部１３９とを備えている。具体的には、中央制御装置１０３は、中央演算装置と、メモリと、インターフェースとを備えたコンピュータに特定のプログラムを実行させることにより実現されている。 The central control device 103 is a computer or the like that controls the traveling vehicle system 100, and includes a charging instruction unit 131 and a power saving control unit 132. In the case of the present embodiment, the central controller 103 further includes a travel monitoring unit 133 and a communication unit 139. Specifically, the central controller 103 is realized by causing a computer having a central processing unit, a memory, and an interface to execute a specific program.
　なお、中央制御装置１０３が備える各処理部は、コンピュータにソフトウエアを実行させることにより実現されるものを例示することができるが、これに限定されるものではなく、一部にハードウエアを含むものや全部がハードウエアにより実現されるものでもかまわない。 In addition, although each process part with which the central control apparatus 103 is provided can illustrate what is implement | achieved by making a computer run software, it is not limited to this, A hardware is included in one part Things or everything can be realized by hardware.
　また、本実施の形態の場合、中央制御装置１０３として１台のコンピュータのように記載しているが、複数のコンピュータが役割を分担していてもかまわない。 In the present embodiment, the central controller 103 is described as a single computer, but a plurality of computers may share the role.
　充電指示部１３１は、走行車１０１に搭載される蓄電装置１１１を充電するために給電線１２２の存在する充電領域１２１に複数の走行車１０１を配置する処理部である。充電指示部１３１は、走行車システム１００が通常操業している際には動作することは無く、例えば、走行車システム１００の操業が中断する夜間の始めに動作する。また、例えば搬送要求が存在しないために一定期間に走行車１０１が走行しない旨の情報を操業計画情報などから入手した場合、充電指示部１３１が動作してもかまわない。 The charging instruction unit 131 is a processing unit that arranges the plurality of traveling vehicles 101 in the charging area 121 where the power supply line 122 exists in order to charge the power storage device 111 mounted on the traveling vehicle 101. The charging instruction unit 131 does not operate when the traveling vehicle system 100 is normally operating, and operates, for example, at the beginning of the night when the operation of the traveling vehicle system 100 is interrupted. Further, for example, when information indicating that the traveling vehicle 101 does not travel for a certain period of time because there is no transport request is obtained from the operation plan information, the charging instruction unit 131 may operate.
　具体的に例えば充電指示部１３１は、走行車１０１（例えば全ての走行車１０１）が一定の期間において荷物の移載や走行などを行わない場合に、図３に示す状態となるように、充電領域１２１に向かい、かつ、充電領域１２１内で待機する旨を示す情報を対象となる走行車１０１に対し送信する。なお、当該通信は、通信部１３９を介して各走行車１０１と通信する。 Specifically, for example, the charging instruction unit 131 performs charging so that the state shown in FIG. 3 is obtained when the traveling vehicle 101 (for example, all the traveling vehicles 101) does not transfer or travel a load during a certain period. Information indicating that the vehicle heads to the area 121 and stands by in the charging area 121 is transmitted to the target traveling vehicle 101. The communication communicates with each traveling vehicle 101 via the communication unit 139.
　省電力制御部１３２は、充電領域１２１で充電されている蓄電装置１１１の蓄電状態を監視し、充電領域１２１において充電状態となっている全ての走行車１０１の蓄電装置１１１の蓄電状態が満状態である場合に充電装置１０２を停止させ、充電領域１２１において充電状態となっている走行車１０１のいずれかの蓄電装置１１１の蓄電状態が欠乏状態である場合に充電装置１０２を稼働させる処理部である。 The power saving control unit 132 monitors the power storage state of the power storage device 111 that is charged in the charging area 121, and the power storage state of the power storage devices 111 of all the traveling vehicles 101 that are in the charging state in the charging area 121 is full. A processing unit that stops the charging device 102 when the power storage device is in the charging region 121 and operates the charging device 102 when the power storage device 111 of the traveling vehicle 101 that is in the charging state in the charging region 121 is in a deficient state. is there.
　具体的に例えば省電力制御部１３２は、充電領域１２１内で停止している各走行車１０１と通信部１３９を介して通信し、各走行車１０１の蓄電情報通知部１１２から送信される情報の全てが満状態を示している場合は、充電装置１０２を停止させる命令を充電装置１０２に送信し、各走行車１０１の蓄電情報通知部１１２から送信される情報のいずれかが欠乏状態を示している場合は、充電装置１０２を稼働させる命令を充電装置１０２に送信する。 Specifically, for example, the power saving control unit 132 communicates with each traveling vehicle 101 stopped in the charging area 121 via the communication unit 139, and transmits the information transmitted from the storage information notification unit 112 of each traveling vehicle 101. If all indicate a full state, a command to stop the charging device 102 is transmitted to the charging device 102, and any of the information transmitted from the storage information notification unit 112 of each traveling vehicle 101 indicates a deficiency state. If so, a command for operating the charging device 102 is transmitted to the charging device 102.
　なお、蓄電情報通知部１１２が蓄電装置１１１の出力電圧などを示す情報を送信する場合、省電力制御部１３２は、通信部１３９を介して受信した各走行車１０１の情報に基づき、蓄電装置１１１の出力電圧などの蓄電状態を示す情報が全ての走行車１０１について第一閾値以上の場合、蓄電状態が満状態であるとして充電装置１０２を停止させる命令を充電装置１０２に送信し、出力電圧などの蓄電状態を示す情報が第一閾値よりも低い第二閾値以下である走行車１０１がある場合、充電装置１０２を稼働させる命令を充電装置１０２に送信するものでもよい。 When the power storage information notification unit 112 transmits information indicating the output voltage of the power storage device 111, the power saving control unit 132 is based on the information on each traveling vehicle 101 received via the communication unit 139. If the information indicating the storage state, such as the output voltage, is equal to or greater than the first threshold for all the traveling vehicles 101, an instruction to stop the charging device 102 is transmitted to the charging device 102 because the storage state is full, and the output voltage, etc. When there is a traveling vehicle 101 whose information indicating the storage state of the vehicle is equal to or lower than the second threshold value which is lower than the first threshold value, a command for operating the charging device 102 may be transmitted to the charging device 102.
　走行監視部１３３は、経路１１０上の複数の走行車１０１の走行状態（例えば全台数の走行状態）を監視し、所定の期間内において走行車１０１が走行状態にない場合、充電領域１２１に対象となる複数の走行車１０１を配置するように充電指示部１３１に指示する処理部である。 The traveling monitoring unit 133 monitors the traveling state (for example, the traveling state of all the vehicles) of the plurality of traveling vehicles 101 on the route 110. If the traveling vehicle 101 is not in the traveling state within a predetermined period, the traveling monitoring unit 133 targets the charging area 121. It is a processing unit that instructs the charging instruction unit 131 to arrange a plurality of traveling vehicles 101.
　具体的に例えば、走行監視部１３３は、走行車システム１００の走行車１０１の走行状態をリアルタイムで監視し、全ての走行車１０１が所定の期間内において走行していない場合、さらに一定期間は走行車１０１が走行しないことを予測して、充電指示部１３１を動作させる情報を送信する。 Specifically, for example, the traveling monitoring unit 133 monitors the traveling state of the traveling vehicle 101 of the traveling vehicle system 100 in real time, and when all the traveling vehicles 101 are not traveling within a predetermined period, the traveling monitoring unit 133 further travels for a certain period. Information that causes the charging instruction unit 131 to operate is transmitted by predicting that the car 101 does not travel.
　次に、走行車システムの省電力方法について説明する。 Next, the power saving method of the traveling vehicle system will be described.
　図４は、走行車システムの省電力方法を示すフローチャートである。 FIG. 4 is a flowchart showing a power saving method of the traveling vehicle system.
　同図に示すように、中央制御装置１０３は、走行車システム１００において稼働している全ての走行車１０１が所定の期間走行するか否かを判断する（Ｓ１０１、走行監視ステップ）。 As shown in the figure, the central controller 103 determines whether or not all the traveling vehicles 101 operating in the traveling vehicle system 100 travel for a predetermined period (S101, travel monitoring step).
　具体的に例えば、走行車システム１００が設置されている工場において、２２時から翌朝の４時までは操業しないという場合などは、走行監視ステップでは、２２時になれば走行車１０１が所定の期間走行しないと判断する。また、走行監視ステップにおいては、操業計画などから走行車１０１が所定の期間走行するか否かを判断してもよく、走行監視部１３３からの情報に基づいてもかまわない。 Specifically, for example, in a factory where the traveling vehicle system 100 is installed, when the operation is not performed from 22:00 to 4:00 the next morning, the traveling vehicle 101 travels for a predetermined period at 22:00 in the traveling monitoring step. Judge not to. Further, in the travel monitoring step, it may be determined whether the traveling vehicle 101 travels for a predetermined period from an operation plan or the like, and may be based on information from the travel monitoring unit 133.
　次に、走行監視ステップにおいて全ての走行車１０１が所定の期間走行しないと判断されると（Ｓ１０１：Ｎ）、充電指示部１３１は、充電領域１２１に向かい、充電領域１２１内で停止させる命令を全走行車１０１に対し送信する（Ｓ１０２、充電指示ステップ）。 Next, when it is determined in the travel monitoring step that all the traveling vehicles 101 do not travel for a predetermined period (S101: N), the charging instruction unit 131 proceeds to the charging area 121 and issues a command to stop the charging area 121. It transmits with respect to all the traveling vehicles 101 (S102, charge instruction | indication step).
　以上により、走行車１０１は、図３に示すように充電領域１２１内に並んだ状態で停止する。 As described above, the traveling vehicle 101 stops in a state of being lined up in the charging area 121 as shown in FIG.
　ここで、走行車システム１００の通常操業時においては、走行車１０１は、充電領域１２１を通過することにより蓄電装置１１１が充電されるものとなっており、充電装置１０２は、稼働状態が維持されている。従って、充電指示ステップにより充電領域１２１に集まった停止状態の走行車１０１の蓄電装置１１１は、稼働状態の充電装置１０２により非接触で充電される（省エネ充電モード）。 Here, during normal operation of the traveling vehicle system 100, the traveling vehicle 101 is charged with the power storage device 111 by passing through the charging region 121, and the charging device 102 is maintained in an operating state. ing. Therefore, the power storage device 111 of the stopped traveling vehicle 101 gathered in the charging area 121 in the charging instruction step is charged in a non-contact manner by the operating charging device 102 (energy saving charging mode).
　次に、省電力制御部１３２は、充電領域１２１内で停止している走行車１０１と通信して、蓄電装置１１１の蓄電情報を監視し、対象の走行車１０１の全ての蓄電装置１１１が満状態か否かを判断する（Ｓ１０３、満状態判断ステップ）。 Next, the power saving control unit 132 communicates with the traveling vehicle 101 that is stopped in the charging area 121 to monitor the power storage information of the power storage device 111, and all the power storage devices 111 of the target traveling vehicle 101 are satisfied. It is determined whether or not it is in a state (S103, full state determination step).
　満場体判断ステップにおいて、対象の走行車１０１の全ての蓄電装置１１１が満状態であると判断されると（Ｓ１０３：Ｙ）、省電力制御部１３２は、充電装置１０２を停止させる（Ｓ１０４、充電装置停止ステップ）。 If it is determined in the full body determination step that all the power storage devices 111 of the target traveling vehicle 101 are full (S103: Y), the power saving control unit 132 stops the charging device 102 (S104, charging). Device stop step).
　以上によって、給電線１２２に電流が流れることにより給電線１２２が発熱することを回避することができ、発熱による電力の消費を抑制することができる。 As described above, it is possible to avoid heat generation of the power supply line 122 due to current flowing through the power supply line 122, and it is possible to suppress power consumption due to heat generation.
　次に、走行車１０１には、制御装置や通信装置などが搭載されており、走行車１０１が走行していない間でも制御装置や通信装置などにより蓄電装置１１１に蓄えられた電力は消費される。省電力制御部１３２は、充電装置１０２が停止状態であっても、走行車１０１と通信して、蓄電装置１１１の蓄電情報を監視し、対象となる走行車１０１の蓄電装置１１１のいずれかが欠乏状態であるか否かを判断する（Ｓ１０５、欠乏状態判断ステップ）。 Next, the traveling vehicle 101 is equipped with a control device, a communication device, and the like, and the electric power stored in the power storage device 111 by the control device, the communication device, etc. is consumed even when the traveling vehicle 101 is not traveling. . The power saving control unit 132 communicates with the traveling vehicle 101 even when the charging device 102 is in a stopped state, monitors the power storage information of the power storage device 111, and any of the power storage devices 111 of the target traveling vehicle 101 It is determined whether or not a deficiency state is present (S105, deficiency state determination step).
　欠乏状態判断ステップにおいて、対象の走行車１０１のいずれかの蓄電装置１１１が欠乏状態であると判断されると（Ｓ１０５：Ｙ）、省電力制御部１３２は、充電装置１０２の稼働を再開させる（Ｓ１０６、稼働ステップ）。 In the deficiency state determination step, when it is determined that any power storage device 111 of the target traveling vehicle 101 is in a deficiency state (S105: Y), the power saving control unit 132 restarts the operation of the charging device 102 ( S106, operation step).
　以上のフローは、走行車システム１００の通常操業が再開されるまでは繰り返し実施され、省エネモードが実現される。 The above flow is repeated until the normal operation of the traveling vehicle system 100 is resumed, and the energy saving mode is realized.
　以上の走行車システム１００、および、走行車システム１００の省電力方法によれば、走行車１０１への充電に一定期間寄与しない状態の充電装置１０２の稼働を停止して給電線１２２の発熱による電力の消費を回避しつつ、複数の走行車１０１の充電状態を監視し、一つでも蓄電装置１１１に欠乏状態が発生すると、充電装置１０２の稼働を再開して蓄電装置１１１に充電を行うことが可能となる。従って、走行車システム１００全体の省電力化を図りつつ、即座に走行車システム１００の操業を再開することが可能となる。 According to the traveling vehicle system 100 and the power saving method of the traveling vehicle system 100 described above, the operation of the charging device 102 that does not contribute to the charging of the traveling vehicle 101 for a certain period of time is stopped and the electric power generated by the heat generation of the power supply line 122 is stopped. The charging state of the plurality of traveling vehicles 101 is monitored while the power storage device 111 is in a deficient state, and the operation of the charging device 102 can be resumed to charge the power storage device 111 when one of the power storage devices 111 is deficient. It becomes possible. Therefore, it is possible to immediately resume the operation of the traveling vehicle system 100 while reducing the power consumption of the entire traveling vehicle system 100.
