ミキサ車管理システム、ミキサ車管理サーバ、ミキサ車及びミキサ車管理方法Mixer vehicle management system, mixer vehicle management server, mixer vehicle and mixer vehicle management method
　本発明は、ミキサ車の部品の交換時期を管理可能なミキサ車管理システム、ミキサ車管理サーバ、ミキサ車及びミキサ車管理方法に関する。 The present invention relates to a mixer vehicle management system, a mixer vehicle management server, a mixer vehicle, and a mixer vehicle management method capable of managing the replacement time of parts of the mixer vehicle.
　従来から、モルタルやレディミクストコンクリート等（以下、「生コン」という。）を搭載可能なミキサドラムを備えるミキサ車が、例えば土木・建築の工事現場において用いられている。 Conventionally, mixer trucks equipped with a mixer drum on which mortar, ready-mixed concrete, etc. (hereinafter referred to as “raw concrete”) can be mounted have been used, for example, in civil engineering and construction sites.
　当該ミキサ車は、エンジンから回転動力を取り出し、それを流体圧（油圧）ポンプへ伝達し、流体圧（油圧）ポンプから吐出される圧流体（圧油）を流体圧（油圧）モータへ供給してこれを回転駆動させ、その回転によりミキサドラムを回転駆動させることで、ミキサドラムに搭載された生コンを常時攪拌しながら上記工事現場へ輸送する。（例えば、特許文献１参照）。 The mixer truck extracts rotational power from the engine, transmits it to a fluid pressure (hydraulic pressure) pump, and supplies pressure fluid (pressure oil) discharged from the fluid pressure (hydraulic pressure) pump to a fluid pressure (hydraulic pressure) motor. This is rotated, and the mixer drum is driven to rotate by that rotation, so that the raw concrete mounted on the mixer drum is transported to the construction site while being constantly stirred. (For example, refer to Patent Document 1).

　当然ながら、上記ミキサ車が有する上記ミキサドラム、流体圧ポンプ、流体圧モータといった部品には、それぞれ交換時期または寿命が存在する。しかし、現場の作業者やミキサ車の所有者等がそれら部品の交換時期等をそもそも把握していることは少ないため、当該交換時期を適切に判断することは困難であり、また交換時期に関する知識を有していたとしても、それを管理するのは非常に面倒である。したがって交換時期の把握は、メンテナンス業者による人手を介した確認作業に頼らざるを得ない。 Of course, parts such as the mixer drum, fluid pressure pump, and fluid pressure motor of the mixer vehicle have a replacement time or a lifetime. However, it is difficult for workers in the field and mixer truck owners to grasp the replacement timing of these parts in the first place, so it is difficult to properly determine the replacement timing. Even if you have it, it is very cumbersome to manage it. Therefore, the grasp of the replacement time must be relied upon by a manual confirmation operation by a maintenance company.
　それら部品の中でも流体圧ポンプは常にエンジンの駆動と連動して回転しており、特に負荷の掛かる部品であるということができ、その交換時期や寿命は適切に把握される必要がある。 Among these parts, the fluid pressure pump always rotates in conjunction with the engine drive, and it can be said that it is a particularly heavy part, and its replacement time and life need to be properly grasped.
　以上のような事情に鑑み、本発明の目的は、ミキサ車の流体圧ポンプの交換時期を、人手を介さずに適切に検知することが可能なミキサ車管理システム、ミキサ車管理サーバ、ミキサ車及びミキサ車管理方法を提供することにある。 In view of the circumstances as described above, an object of the present invention is to provide a mixer vehicle management system, a mixer vehicle management server, and a mixer vehicle that can appropriately detect the replacement timing of the fluid pressure pump of the mixer vehicle without human intervention. And providing a mixer vehicle management method.
　上記目的を達成するため、本発明の一形態に係るミキサ車管理システムは、ミキサ車と管理サーバとを有する。
　上記ミキサ車は、ミキサドラムと、流体圧ポンプと、ミキサ車通信部と、ミキサ車制御部とを有する。上記流体圧ポンプは、駆動時に作動流体の吐出圧によって上記ミキサドラムを回転させることが可能である。上記ミキサ車通信部は、上記管理サーバと通信可能である。上記ミキサ車制御部は、上記流体圧ポンプにおいて所定値以上の上記吐出圧が発生している負荷時間を取得して負荷時間情報を生成可能であり、上記生成された負荷時間情報を上記管理サーバへ送信するように上記ミキサ車通信部を制御可能である。
　上記管理サーバは、サーバ通信部と、記憶部と、サーバ制御部とを有する。上記サーバ通信部は、上記ミキサ車と通信可能である。上記記憶部は、上記負荷時間に関する閾値を示す閾値情報を記憶可能である。上記サーバ制御部は、上記送信された負荷時間情報を受信するように上記サーバ通信部を制御可能であり、上記受信された負荷時間情報によって示される負荷時間の積算時間が上記閾値以上であるか否かを判断し、上記積算時間が上記閾値以上であると判断した場合に、上記流体圧ポンプの交換時期を示す交換時期情報を生成可能である。 In order to achieve the above object, a mixer truck management system according to an aspect of the present invention includes a mixer truck and a management server.
The mixer vehicle includes a mixer drum, a fluid pressure pump, a mixer vehicle communication unit, and a mixer vehicle control unit. The fluid pressure pump can rotate the mixer drum by the discharge pressure of the working fluid during driving. The mixer vehicle communication unit can communicate with the management server. The mixer truck control unit can generate load time information by acquiring a load time during which the discharge pressure of a predetermined value or more is generated in the fluid pressure pump, and the generated load time information is stored in the management server. The mixer vehicle communication section can be controlled to transmit to
The management server includes a server communication unit, a storage unit, and a server control unit. The server communication unit can communicate with the mixer vehicle. The said memory | storage part can memorize | store the threshold value information which shows the threshold value regarding the said load time. Whether the server control unit can control the server communication unit to receive the transmitted load time information, and whether the accumulated time of the load time indicated by the received load time information is equal to or greater than the threshold value. When it is determined whether or not the accumulated time is equal to or greater than the threshold value, replacement time information indicating the replacement time of the fluid pressure pump can be generated.
　これによりミキサ車管理システムは、ミキサ車の流体圧ポンプの交換時期を、人手を介さずに適切に検知することができる。 This makes it possible for the mixer truck management system to properly detect the replacement time of the fluid pressure pump of the mixer truck without human intervention.
　上記サーバ通信部は、上記ミキサ車の所有者が有する所有者サーバと通信可能であってもよい。この場合上記サーバ制御部は、上記生成された交換時期情報を基に、上記所有者サーバへ、上記交換時期を報知する報知情報を送信するように上記サーバ通信部を制御してもよい。 The server communication unit may be able to communicate with an owner server owned by the owner of the mixer vehicle. In this case, the server control unit may control the server communication unit so as to transmit notification information for notifying the replacement time to the owner server based on the generated replacement time information.
　これによりミキサ車管理システムは、流体圧ポンプの交換時期をミキサ車の所有者に報知し、適宜交換用の流体圧ポンプの購入等の措置を講じさせることができる。ここで所有者には、ミキサ車のレンタル会社も含まれる。 This allows the mixer truck management system to notify the owner of the mixer truck of the replacement timing of the fluid pressure pump and to take measures such as purchasing a replacement fluid pressure pump as appropriate. Here, the owner includes a rental company for a mixer truck.
　上記記憶部は、上記閾値として、第１閾値と、当該第１閾値よりも大きい第２閾値とを示す情報を記憶してもよい。この場合上記サーバ制御部は、上記積算時間が上記第１閾値以上上記第２閾値未満であると判断した場合に上記交換時期情報を生成し、上記積算時間が上記第２閾値以上であると判断した場合に、上記流体圧ポンプの寿命時期を示す寿命時期情報を生成してもよい。 The storage unit may store information indicating a first threshold and a second threshold larger than the first threshold as the threshold. In this case, the server control unit generates the replacement time information when it is determined that the accumulated time is not less than the first threshold value and less than the second threshold value, and is determined that the accumulated time is not less than the second threshold value. In this case, life time information indicating the life time of the fluid pressure pump may be generated.
　これによりミキサ車管理システムは、流体圧ポンプの交換時期のみならず寿命時期も人手を介さずに適切に検知することができる。 This enables the mixer truck management system to properly detect not only the replacement time of the fluid pressure pump but also the life time without human intervention.
　上記サーバ通信部は、上記ミキサ車の所有者が有する所有者サーバと通信可能であってもよい。この場合上記サーバ制御部は、上記生成された交換時期情報を基に、上記所有者サーバへ、上記交換時期を報知する第１の報知情報を送信し、上記生成された寿命時期情報を基に、上記所有者サーバへ、上記寿命時期を報知する第２の報知情報を送信するように上記サーバ通信部を制御してもよい。 The server communication unit may be able to communicate with an owner server owned by the owner of the mixer vehicle. In this case, the server control unit transmits first notification information for notifying the replacement time to the owner server based on the generated replacement time information, and based on the generated life time information. The server communication unit may be controlled to transmit second notification information for notifying the lifetime to the owner server.
　これによりミキサ車管理システムは、流体圧ポンプの交換時期をミキサ車の所有者に報知することで適宜交換用の流体圧ポンプの購入等の措置を講じさせることができ、またさらに寿命時期も報知することで、ミキサ車の使用を停止させる等の措置を講じさせることができる。 As a result, the mixer truck management system can inform the owner of the mixer truck of the replacement timing of the fluid pressure pump so that it can take measures such as purchasing a replacement fluid pressure pump as appropriate, and also notify the end of life. By doing so, it is possible to take measures such as stopping the use of the mixer truck.
　上記ミキサ車は、音声出力部を有してもよい。この場合上記サーバ制御部は、上記生成された交換時期情報を基に、上記ミキサ車へ、上記交換時期を報知する第１の報知情報を送信し、上記生成された寿命時期情報を基に、上記ミキサ車へ、上記寿命時期を報知する第２の報知情報を送信するように上記サーバ通信部を制御してもよい。この場合上記ミキサ車制御部は、上記送信された第１の報知情報または第２の報知情報を受信するように上記ミキサ車通信部を制御し、上記第１の報知情報が受信された場合に、第１の音量の第１の報知音を出力するように上記音声出力部を制御し、上記第２の報知情報が受信された場合に、上記第１の音量よりも大きい第２の音量の第２の報知音を出力するように上記音声出力部を制御してもよい。 The mixer vehicle may have an audio output unit. In this case, the server control unit transmits first notification information for notifying the replacement time to the mixer vehicle based on the generated replacement time information, and based on the generated life time information. You may control the said server communication part so that the 2nd alerting | reporting information which alert | reports the said lifetime is transmitted to the said mixer vehicle. In this case, the mixer vehicle control unit controls the mixer vehicle communication unit to receive the transmitted first notification information or second notification information, and when the first notification information is received. The sound output unit is controlled to output the first notification sound having the first volume, and when the second notification information is received, a second volume larger than the first volume is received. The voice output unit may be controlled so as to output the second notification sound.
　これによりミキサ車管理システムは、ミキサ車を運転中の運転者に、運転を停止させることなく、流体圧ポンプの交換時期及び寿命時期をそれぞれ区別して把握させることができる。 This allows the mixer vehicle management system to distinguish and grasp the replacement time and the life time of the fluid pressure pump, without stopping the operation of the mixer vehicle.
　上記ミキサ車は、当該ミキサ車の位置情報を取得する位置情報取得部を有してもよい。この場合上記ミキサ車制御部は、上記取得された位置情報を上記管理サーバへ送信するように上記通信部を制御してもよい。一方上記記憶部は、平均気温の異なる複数の位置情報にそれぞれ対応する複数の異なる閾値を示す閾値情報を記憶してもよい。この場合上記サーバ制御部は、上記送信された位置情報を受信するように上記サーバ通信部を制御し、上記積算時間が上記位置情報に対応する閾値以上であると判断した場合に、上記交換時期情報を生成してもよい。 The mixer vehicle may include a position information acquisition unit that acquires position information of the mixer vehicle. In this case, the mixer vehicle control unit may control the communication unit to transmit the acquired position information to the management server. On the other hand, the storage unit may store threshold information indicating a plurality of different threshold values respectively corresponding to a plurality of pieces of position information having different average temperatures. In this case, the server control unit controls the server communication unit to receive the transmitted position information, and determines that the replacement time is determined when it is determined that the accumulated time is equal to or greater than a threshold corresponding to the position information. Information may be generated.
　これによりミキサ車管理システムは、流体圧ポンプの作動流体の粘性が気温によって異なることで負荷に違いが生じる結果、交換時期にも違いが生じることを考慮して、流体圧ポンプが駆動しているときの位置（気温）に応じて高精度に交換時期を検知することができる。 As a result, in the mixer truck management system, the fluid pressure pump is driven in consideration of the difference in load as a result of the difference in load caused by the viscosity of the working fluid of the fluid pressure pump depending on the temperature. The replacement time can be detected with high accuracy in accordance with the position (temperature) at the time.
　本発明の他の形態に係るミキサ車管理サーバは、通信部と、記憶部と、制御部とを有する。上記通信部は、駆動時に作動流体の吐出圧によってミキサドラムを回転させることが可能な流体圧ポンプを有するミキサ車と通信可能である。上記記憶部は、上記流体圧ポンプにおいて所定値以上の上記吐出圧が発生している負荷時間に関する閾値を示す閾値情報を記憶可能である。上記制御部は、上記ミキサ車との通信により、上記負荷時間を示す負荷時間情報を取得し、上記受信された負荷時間情報によって示される負荷時間の積算時間が上記閾値以上であるか否かを判断し、上記積算時間が上記閾値以上であると判断した場合に、上記流体圧ポンプの交換時期を示す交換時期情報を生成可能である。 A mixer vehicle management server according to another embodiment of the present invention includes a communication unit, a storage unit, and a control unit. The communication unit can communicate with a mixer vehicle having a fluid pressure pump capable of rotating the mixer drum by the discharge pressure of the working fluid during driving. The said memory | storage part can memorize | store the threshold value information which shows the threshold value regarding the load time when the said discharge pressure more than predetermined value has generate | occur | produced in the said fluid pressure pump. The control unit acquires load time information indicating the load time through communication with the mixer vehicle, and determines whether or not an accumulated time of the load time indicated by the received load time information is equal to or greater than the threshold value. When it is determined that the accumulated time is greater than or equal to the threshold value, replacement time information indicating the replacement time of the fluid pressure pump can be generated.
　本発明のまた別の形態に係るミキサ車は、ミキサドラムと、流体圧ポンプと、通信部と、制御部とを有する。上記流体圧ポンプは、駆動時に作動流体の吐出圧によって上記ミキサドラムを回転させることが可能である。上記通信部は、管理サーバと通信可能である。上記制御部は、上記流体圧ポンプにおいて所定値以上の上記吐出圧が発生している負荷時間を取得して負荷時間情報を生成し、上記生成された負荷時間情報を上記管理サーバへ送信するよう上記通信部を制御可能である。 A mixer vehicle according to still another embodiment of the present invention includes a mixer drum, a fluid pressure pump, a communication unit, and a control unit. The fluid pressure pump can rotate the mixer drum by the discharge pressure of the working fluid during driving. The communication unit can communicate with the management server. The control unit acquires a load time during which the discharge pressure equal to or higher than a predetermined value is generated in the fluid pressure pump, generates load time information, and transmits the generated load time information to the management server. The communication unit can be controlled.
　本発明のさらに別の形態に係るミキサ車管理方法は、

［システムの概要］
　図１は、本発明の一実施形態に係るミキサ車管理システムの概要を示す図である。 [System Overview]
FIG. 1 is a diagram showing an overview of a mixer vehicle management system according to an embodiment of the present invention.
　同図に示すように、本システムは、ミキサ車１００と、管理サーバ２００と、ユーザサーバ３００と、レンタル会社サーバ４００とを有する。 As shown in the figure, the present system includes a mixer truck 100, a management server 200, a user server 300, and a rental company server 400.
　ミキサ車１００は、モルタルやレディミクストコンクリート等（以下、「生コン」という。）を搭載してそれを土木や建築の工事現場へ輸送する車両であり、例えば
無線基地局（図示せず）及びインターネット５０を介して管理サーバ２００と通信可能とされている。 The mixer truck 100 is a vehicle that carries mortar, ready-mixed concrete, etc. (hereinafter referred to as “raw concrete”) and transports it to a construction site for civil engineering or construction. 50, communication with the management server 200 is possible.

［ミキサ車の構成］
　図２は、上記ミキサ車１００の平面図であり、図３は、上記ミキサ車１００のハードウェア構成を示すブロック図である。両図を用いてミキサ車１００の全体構成について説明する。 [Configuration of mixer truck]
FIG. 2 is a plan view of the mixer truck 100, and FIG. 3 is a block diagram showing a hardware configuration of the mixer truck 100. The overall configuration of the mixer truck 100 will be described with reference to both drawings.
　図２に示すように、ミキサドラム２内に生コンを搭載して運搬する車両である。ミキサ車１００は、運転室１１と、架台１と、架台１に搭載されて生コンを搭載可能なミキサドラム２と、ミキサドラム２を回転駆動する駆動装置４と、ミキサ車１００の各ブロックを制御するコントローラ１０とを有する。 As shown in FIG. 2, the vehicle is a vehicle that is loaded with a live concrete in the mixer drum 2. The mixer vehicle 100 includes an operator cab 11, a gantry 1, a mixer drum 2 mounted on the gantry 1 and capable of mounting a raw control unit, a driving device 4 that rotationally drives the mixer drum 2, and a controller that controls each block of the mixer vehicle 100 10 and.
　生コンは、生コン業者のプラントにおいてセメント，骨材，水，などの材料から生成され、ミキサ車１００のミキサドラム２内に投入されてミキサドラム２の回転駆動により撹拌される。 The ready-mixed concrete is generated from materials such as cement, aggregate, water, etc. in the ready-mixed company's plant, is put into the mixer drum 2 of the mixer truck 100, and is agitated by the rotational drive of the mixer drum 2.
　ミキサドラム２は、架台１に回転可能に搭載される有底円筒形の容器である。ミキサドラム２は、回転軸が車両の前後方向を向くように搭載される。ミキサドラム２は、車両の後部に向かって徐々に高くなるように、前後に傾斜して搭載される。 The mixer drum 2 is a bottomed cylindrical container that is rotatably mounted on the gantry 1. The mixer drum 2 is mounted such that the rotating shaft faces the front-rear direction of the vehicle. The mixer drum 2 is mounted so as to be inclined forward and backward so as to gradually increase toward the rear of the vehicle.
　ミキサドラム２の後端には開口部が形成され、開口部から生コンの投入と排出とが可能である。ミキサドラム２は、ミキサ車１００に搭載された走行用のエンジン３を動力源として回転駆動される。 An opening is formed at the rear end of the mixer drum 2, and raw food can be charged and discharged from the opening. The mixer drum 2 is rotationally driven using a traveling engine 3 mounted on the mixer vehicle 100 as a power source.
　駆動装置４は、エンジン３の回転によって駆動され、作動流体の流体圧によってミキサドラム２を回転駆動する。エンジン３におけるクランクシャフトの回転運動は、エンジン３から動力を常時取り出すための動力取り出し機構９（ＰＴＯ：Power Take-Off）と、動力取り出し機構９と駆動装置４とを連結するドライブシャフト８とによって駆動装置４に伝達される。 The driving device 4 is driven by the rotation of the engine 3 and rotationally drives the mixer drum 2 by the fluid pressure of the working fluid. The rotational movement of the crankshaft in the engine 3 is caused by a power take-out mechanism 9 (PTO: Power-Take-Off) for constantly taking power from the engine 3 and a drive shaft 8 connecting the power take-out mechanism 9 and the drive device 4. It is transmitted to the driving device 4.
　図３に示すように、動力取り出し機構９には、その回転数を検出し、検出した回転数に応じた回転数信号をコントローラ１０に送信する回転センサ９ａが設けられる。回転センサ９ａは、ドライブシャフト８の回転数を検出するように設けられてもよい。 As shown in FIG. 3, the power take-out mechanism 9 is provided with a rotation sensor 9a that detects the rotation speed and transmits a rotation speed signal corresponding to the detected rotation speed to the controller 10. The rotation sensor 9a may be provided so as to detect the rotational speed of the drive shaft 8.
　駆動装置４では、作動流体として作動油が用いられる。作動油ではなく、他の非圧縮性流体が作動流体として用いられてもよい。図２に示すように、駆動装置４は、エンジン３によって駆動されて作動流体を吐出する流体圧ポンプとしての油圧ポンプ５と、油圧ポンプ５によって駆動されてミキサドラム２を回転駆動する流体圧モータとしての油圧モータ６とを有する。駆動装置４は、ミキサドラム２を正逆転及び増減速させることが可能である。 In the driving device 4, hydraulic oil is used as the working fluid. Instead of hydraulic oil, other incompressible fluids may be used as the hydraulic fluid. As shown in FIG. 2, the driving device 4 is a hydraulic pump 5 as a fluid pressure pump that is driven by the engine 3 to discharge the working fluid, and a fluid pressure motor that is driven by the hydraulic pump 5 to rotationally drive the mixer drum 2. The hydraulic motor 6 is provided. The drive device 4 can forward / reverse and increase / decrease the mixer drum 2.
　油圧ポンプ５は、動力取り出し機構９を介してエンジン３から常時取り出される動力によって回転駆動される。そのため、油圧ポンプ５の回転数は、車両の走行状態に伴うエンジン３の回転数の変化に、大きく影響を受ける。そこで、ミキサ車１００は、エンジン３の回転速度に応じてミキサドラム２が目標回転状態となるように、コントローラ１０によって油圧ポンプ５と油圧モータ６との動作を制御している。 The hydraulic pump 5 is rotationally driven by the power that is always taken out from the engine 3 through the power take-out mechanism 9. Therefore, the rotational speed of the hydraulic pump 5 is greatly affected by a change in the rotational speed of the engine 3 accompanying the traveling state of the vehicle. Therefore, the mixer vehicle 100 controls the operation of the hydraulic pump 5 and the hydraulic motor 6 by the controller 10 so that the mixer drum 2 is in the target rotation state according to the rotational speed of the engine 3.
　油圧ポンプ５は、例えば容量が可変な斜板型アキシャルピストンポンプである。油圧ポンプ５は、コントローラ１０からの指令信号を受信してポンプの傾転角を正転方向又は逆転方向に切り換える。油圧ポンプ５は、その傾転角を調整するための電磁弁を有する。この電磁弁が切り換えられることによって、油圧ポンプ５の吐出方向と吐出容量が調整される。 The hydraulic pump 5 is, for example, a swash plate type axial piston pump having a variable capacity. The hydraulic pump 5 receives the command signal from the controller 10 and switches the tilt angle of the pump to the forward rotation direction or the reverse rotation direction. The hydraulic pump 5 has a solenoid valve for adjusting the tilt angle. By switching the solenoid valve, the discharge direction and discharge capacity of the hydraulic pump 5 are adjusted.
　油圧ポンプ５から吐出された作動油は油圧モータ６に供給され、これにより油圧モータ６が回転する。油圧モータ６には、減速機７を介してミキサドラム２が連結される。これにより、ミキサドラム２が、油圧モータ６の回転に伴って回転する。 The hydraulic oil discharged from the hydraulic pump 5 is supplied to the hydraulic motor 6, and the hydraulic motor 6 rotates thereby. The mixer drum 2 is connected to the hydraulic motor 6 via a speed reducer 7. As a result, the mixer drum 2 rotates as the hydraulic motor 6 rotates.
　油圧ポンプ５によってミキサドラム２が正転運転されるときには、ミキサドラム２内の生コンが攪拌される。一方、油圧ポンプ５によってミキサドラム２が逆転運転されるときには、ミキサドラム２内の生コンが後端の開口部から外部へと排出される。 When the mixer drum 2 is rotated in the forward direction by the hydraulic pump 5, the raw steam in the mixer drum 2 is agitated. On the other hand, when the mixer drum 2 is operated in reverse by the hydraulic pump 5, the raw control in the mixer drum 2 is discharged from the opening at the rear end to the outside.
　油圧ポンプ５から吐出される作動油の油圧は、ミキサドラム２内に搭載される生コンの搭載量とスランプ（生コンの流動性を示す数値）とに応じて変化する。油圧ポンプ５には、吐出される作動油の圧力を検出する圧力検出器としての圧力センサ５ａ（図３参照）が設けられる。 The hydraulic pressure of the hydraulic oil discharged from the hydraulic pump 5 varies depending on the amount of raw control mounted in the mixer drum 2 and the slump (a numerical value indicating the fluidity of the raw control). The hydraulic pump 5 is provided with a pressure sensor 5a (see FIG. 3) as a pressure detector that detects the pressure of discharged hydraulic oil.
　図３に示すように、圧力センサ５ａは、検出した作動油の圧力に応じて、コントローラ１０に負荷圧力信号を送信する。圧力センサ５ａが油圧ポンプ５に設けられずに、油圧モータ６に設けられ、油圧モータ６における作動油の圧力が検出されてもよい。 As shown in FIG. 3, the pressure sensor 5a transmits a load pressure signal to the controller 10 in accordance with the detected pressure of the hydraulic oil. The pressure sensor 5a may be provided in the hydraulic motor 6 without being provided in the hydraulic pump 5, and the pressure of the hydraulic oil in the hydraulic motor 6 may be detected.
　油圧モータ６は、例えば容量が可変な斜板型アキシャルピストンモータである。油圧モータ６は、油圧ポンプ５から吐出された作動油の供給を受けて回転駆動される。油圧モータ６は、コントローラ１０からの指令信号を受信してモータの傾転角を調整する電磁弁を備える。この電磁弁が切り換えられることによって、油圧モータ６の容量が、高速回転用の小容量と通常回転用の大容量との二段階に切り換えられる。 The hydraulic motor 6 is, for example, a swash plate type axial piston motor having a variable capacity. The hydraulic motor 6 is rotationally driven in response to the supply of hydraulic oil discharged from the hydraulic pump 5. The hydraulic motor 6 includes an electromagnetic valve that receives a command signal from the controller 10 and adjusts the tilt angle of the motor. By switching this electromagnetic valve, the capacity of the hydraulic motor 6 is switched in two stages, a small capacity for high speed rotation and a large capacity for normal rotation.

The load time information generation unit 111 acquires load time during which the discharge pressure of a predetermined value or more is generated when the hydraulic pump is driven, and generates load time information.
　具体的には、負荷時間情報生成部１１１は、上記圧力センサ５ａから受信される負荷圧力信号が所定値以上の吐出圧を示している場合、タイマを起動し、上記負荷圧力信号で示される吐出圧が所定値を下回るまで、負荷時間をカウントする。そして負荷時間情報生成部１１１は、当該カウントされた負荷時間を示す負荷時間情報を生成して、例えば上記ＥＥＰＲＯＭ１２０に記憶する。 Specifically, when the load pressure signal received from the pressure sensor 5a indicates a discharge pressure equal to or higher than a predetermined value, the load time information generation unit 111 starts a timer and discharges indicated by the load pressure signal. The load time is counted until the pressure falls below a predetermined value.

［管理サーバのハードウェア構成］
　図４は、上記管理サーバ２００のハードウェア構成を示したブロック図である。 [Hardware configuration of Management Server]
FIG. 4 is a block diagram showing a hardware configuration of the management server 200.

　タイマ２６０は、管理サーバ２００の各種動作の開始及び終了等に用いられるほか、上記ミキサ車１００の負荷時間情報生成部１１１の処理を管理サーバ２００が代替して実行する場合にも用いられる。 The timer 260 is used not only for starting and ending various operations of the management server 200, but also when the management server 200 executes the processing of the load time information generation unit 111 of the mixer vehicle 100 instead.
　すなわち、管理サーバ２００が、ミキサ車１００から油圧ポンプ５における上記負荷圧力信号が所定値以上の吐出圧を示している旨の通知を受信した場合、ＣＰＵ２１０は、タイマ２６０を起動し、上記負荷圧力信号で示される吐出圧が所定値を下回るまで負荷時間をカウントし、当該カウントされた負荷時間を示す負荷時間情報を生成して、上記記憶部２５０に記憶してもよい。 That is, when the management server 200 receives a notification from the mixer vehicle 100 that the load pressure signal in the hydraulic pump 5 indicates a discharge pressure equal to or higher than a predetermined value, the CPU 210 activates the timer 260 to start the load pressure The load time may be counted until the discharge pressure indicated by the signal falls below a predetermined value, and load time information indicating the counted load time may be generated and stored in the storage unit 250.
　ＣＰＵ２１０は、負荷時間判定部２１１及び報知情報生成部２１２を有する。 The CPU 210 includes a load time determination unit 211 and a notification information generation unit 212.

　同図に示すように、ミキサ車１００のＣＰＵ１１０（負荷時間情報生成部１１１）は、上記イグニッション電源がＯＮになったか否かを判断する（ステップ５１）。 As shown in the figure, the CPU 110 (load time information generation unit 111) of the mixer vehicle 100 determines whether or not the ignition power source is turned on (step 51).
　イグニッション電源がＯＮになったと判断した場合（Ｙｅｓ）、ＣＰＵ１１０は、油圧ポンプ５の吐出圧が発生している負荷時間を検知する（ステップ５２）。 When it is determined that the ignition power source is turned on (Yes), the CPU 110 detects the load time during which the discharge pressure of the hydraulic pump 5 is generated (step 52).
　すなわち、ＣＰＵ１１０は、上記圧力センサ５ａから受信される負荷圧力信号が所定値以上の吐出圧を示している場合、タイマを起動し、上記負荷圧力信号で示される吐出圧が所定値を下回るまで、負荷時間をカウントする。 That is, when the load pressure signal received from the pressure sensor 5a indicates a discharge pressure greater than or equal to a predetermined value, the CPU 110 activates a timer until the discharge pressure indicated by the load pressure signal falls below a predetermined value. Count load time.
　そしてＣＰＵ１１０は、当該カウントされた負荷時間を示す負荷時間情報を生成して、例えば上記ＥＥＰＲＯＭ１２０に記憶する（ステップ５３）。 And CPU110 produces | generates the load time information which shows the said counted load time, for example, memorize | stores it in the said EEPROM120 (step 53).
　ＣＰＵ１１０は、以上の処理を、イグニッション電源がＯＦＦになるまで繰り返す（ステップ５４）。 The CPU 110 repeats the above processing until the ignition power is turned off (step 54).

　続いてＣＰＵ１１０は、当該読み出された負荷時間情報を、通信部２１により、例えば基地局を介して、管理サーバ２００へ送信する（ステップ６３）。 Subsequently, the CPU 110 transmits the read load time information to the management server 200 by the communication unit 21 via, for example, a base station (step 63).
　そしてＣＰＵ１１０はタイマをリセットし、次回の設定時刻が到来すると、上記ステップ６２以降の処理を繰り返す。 Then, the CPU 110 resets the timer, and when the next set time comes, repeats the processing from step 62 onward.

　同図に示すように、管理サーバ２００のＣＰＵ２１０は、ミキサ車１００から負荷時間情報を受信したか否かを判断する（ステップ７１）。 As shown in the figure, the CPU 210 of the management server 200 determines whether or not the load time information is received from the mixer vehicle 100 (step 71).
　負荷時間情報を受信したと判断した場合（Ｙｅｓ）、ＣＰＵ２１０（負荷時間判定部２１１）は、当該負荷時間情報を記憶する（ステップ７２）。それよりも前に負荷時間情報が記憶されている場合、ＣＰＵ２１０は、それら負荷時間情報で示される負荷時間を積算する。 When it is determined that the load time information has been received (Yes), the CPU 210 (load time determination unit 211) stores the load time information (step 72). If the load time information is stored before that, the CPU 210 integrates the load time indicated by the load time information.
　続いてＣＰＵ２１０は、上記負荷時間の積算時間が上記第１閾値以上であるか否かを判断する（ステップ７３）。 Subsequently, the CPU 210 determines whether or not the accumulated time of the load time is equal to or greater than the first threshold value (step 73).
　上記積算時間が第１閾値以上であると判断した場合（Ｙｅｓ）、ＣＰＵ２１０は、当該積算時間が第２閾値以上であるか否かを判断する（ステップ７４）。 If it is determined that the integration time is equal to or greater than the first threshold (Yes), the CPU 210 determines whether or not the integration time is equal to or greater than the second threshold (step 74).
　上記積算時間が第２閾値未満であると判断した場合（Ｎｏ）、ＣＰＵ２１０は、油圧ポンプの交換時期を示す交換時期情報を生成する（ステップ７５）。 If it is determined that the accumulated time is less than the second threshold (No), the CPU 210 generates replacement time information indicating the replacement time of the hydraulic pump (step 75).
　そしてＣＰＵ２１０（報知情報生成部２１２）は、上記交換時期情報を基に、交換時期を報知するための交換時期報知情報を生成し、それを通信部２４０によりミキサ車１００、ユーザサーバ３００、またはレンタル会社サーバ４００へ送信する（ステップ７６）。 Then, the CPU 210 (notification information generation unit 212) generates replacement time notification information for notifying the replacement time based on the replacement time information, and the communication unit 240 generates the replacement time notification information from the mixer vehicle 100, the user server 300, or the rental. It transmits to the company server 400 (step 76).
　一方、上記ステップ７４において上記積算時間が第２閾値以上であると判断した場合（Ｙｅｓ）、ＣＰＵ２１０は、油圧ポンプの寿命時期を示す寿命時期情報を生成する（ステップ７７）。 On the other hand, when it is determined in step 74 that the accumulated time is equal to or greater than the second threshold (Yes), the CPU 210 generates life time information indicating the life time of the hydraulic pump (step 77).
　そしてＣＰＵ２１０（報知情報生成部２１２）は、上記寿命時期情報を基に、寿命時期を報知するための寿命時期報知情報を生成し、それを通信部２４０によりミキサ車１００、ユーザサーバ３００、またはレンタル会社サーバ４００へ送信する（ステップ７８）。 Then, the CPU 210 (notification information generation unit 212) generates life time notification information for notifying the life time based on the life time information, and uses the communication unit 240 to generate the life time notification information. It transmits to the company server 400 (step 78).
（ミキサ車の報知処理）
　図８は、上記ミキサ車１００による報知処理の流れを示すフローチャートである。 (Mixer truck notification process)
FIG. 8 is a flowchart showing a flow of notification processing by the mixer vehicle 100.
　同図に示すように、ミキサ車１００のＣＰＵ１１０は、管理サーバ２００から報知情報を受信したか否かを判断する（ステップ８１）。 As shown in the figure, the CPU 110 of the mixer truck 100 determines whether or not notification information has been received from the management server 200 (step 81).
　報知情報を受信したと判断した場合（Ｙｅｓ）、ＣＰＵ１１０は、当該報知情報が寿命時期報知情報か否かを判断する（ステップ８２）。 If it is determined that the notification information has been received (Yes), the CPU 110 determines whether or not the notification information is lifetime period notification information (step 82).
　上記報知情報が寿命時期報知情報であると判断した場合（Ｙｅｓ）、ＣＰＵ１１０は、上記スピーカ２３から大音量のアラームを出力させると共に、上記ＬＣＤ２２を所定の色で点滅させる（ステップ８４）。 When it is determined that the notification information is life time notification information (Yes), the CPU 110 outputs a loud alarm from the speaker 23 and blinks the LCD 22 in a predetermined color (step 84).
　一方、上記報知情報が交換時期報知情報であると判断した場合（Ｎｏ）、ＣＰＵ１１０は、上記スピーカ２３から通常音量（上記大音量よりも小さい音量）のアラームを出力させると共に、上記ＬＣＤ２２を上記所定の色で点灯させる（ステップ８３）。この場合の色は、上記ステップ８４の場合とは異なる色であってもよい。 On the other hand, when it is determined that the notification information is replacement time notification information (No), the CPU 110 outputs an alarm of a normal volume (a volume lower than the high volume) from the speaker 23 and also causes the LCD 22 to output the predetermined information. The color is turned on (step 83). The color in this case may be a color different from that in step 84 above.
　上記スピーカ２３からのアラーム出力とＬＣＤ２２の点灯または点滅は、両方ではなくいずれか一方が実行されてもよい。 Either one of alarm output from the speaker 23 and lighting or blinking of the LCD 22 may be executed instead of both.
　このような報知処理により、ミキサ車１００を運転中の運転者は、報知情報が受信されたのが運転中であっても、運転を停止させることなく、油圧ポンプ５の交換時期及び寿命時期をそれぞれ区別して把握し、それ相応の措置を講ずることができる。 By such notification processing, the driver operating the mixer vehicle 100 can set the replacement time and the life time of the hydraulic pump 5 without stopping the operation even if the notification information is received. Each can be distinguished and can take appropriate measures.
　同図の処理はミキサ車１００が管理サーバ２００から報知情報を受信した場合の処理であるが、ユーザサーバ３００またはレンタル会社サーバ４００が報知情報を受信した場合には、例えば異なる音量によるアラーム出力や異なる表示形態による報知情報のポップアップ通知等が実行されてもよい。 The process in the figure is a process when the mixer vehicle 100 receives the notification information from the management server 200. However, when the user server 300 or the rental company server 400 receives the notification information, for example, an alarm output with a different volume or Notification information pop-up notifications or the like in different display forms may be executed.
　これによりミキサ車１００のユーザまたはレンタル会社は、使用中のミキサ車１００の油圧ポンプ５の交換時期及び寿命時期を区別して把握することができ、交換時期報知情報を基に新たな油圧ポンプ５を注文したり、寿命時期報知情報を基に新たな油圧ポンプ５の注文と共にミキサ車１００の運転を中止したりすることができる。 As a result, the user or the rental company of the mixer truck 100 can distinguish and grasp the replacement time and the life time of the hydraulic pump 5 of the mixer truck 100 in use, and the new hydraulic pump 5 can be installed based on the replacement time notification information. It is possible to place an order or to stop the operation of the mixer truck 100 together with a new hydraulic pump 5 order based on the life time notification information.
　以上説明したように、本実施形態によれば、ミキサ車管理システムは、ミキサ車１００の油圧ポンプ５の交換時期を、人手を介さずに適切に検知することができ、それを報知することができる。 As described above, according to the present embodiment, the mixer truck management system can appropriately detect and notify the replacement timing of the hydraulic pump 5 of the mixer truck 100 without human intervention. it can.
［変形例］
　本技術は上述の実施形態にのみ限定されるものではなく、本技術の要旨を逸脱しない範囲内において種々変更され得る。 [Modification]
The present technology is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present technology.
　上述の実施形態においては、管理サーバ２００は、閾値情報として第１の閾値と第２の閾値とを用いていた。ところで、油圧ポンプ５の作動油の粘性は、気温によって異なり、気温が低いほど粘性が高くなる。そして、当該粘性の違いによって、油圧ポンプ５に掛かる負荷にも違いが生じる結果、交換時期及び寿命時期にも違いが生じる。 In the above-described embodiment, the management server 200 uses the first threshold value and the second threshold value as threshold information. By the way, the viscosity of the hydraulic oil of the hydraulic pump 5 varies depending on the temperature. The lower the temperature, the higher the viscosity. As a result of the difference in viscosity, the load applied to the hydraulic pump 5 also varies, resulting in a difference in replacement time and life time.
　そこで管理サーバ２００は、ミキサ車１００の稼動時の気温によって上記第１閾値及び第２閾値を可変してもよい。すなわち、ミキサ車１００が例えばＧＰＳ（Global Positioning System）装置等によりミキサ車１００の位置情報を取得し、それを管理サーバ２００へ送信し、一方管理サーバ２００は、平均気温の異なる複数の位置情報にそれぞれ対応する複数の異なる第１閾値及び第２閾値を記憶しておき、上記負荷時間の積算時間が上記ミキサ車１００から受信した位置情報に対応する第１閾値以上または第２閾値以上であると判断した場合に、上記交換時期情報または寿命時期情報を生成してもよい。 Therefore, the management server 200 may vary the first threshold value and the second threshold value depending on the temperature during operation of the mixer vehicle 100. That is, the mixer vehicle 100 acquires the position information of the mixer vehicle 100 by, for example, a GPS (Global Positioning System) device or the like, and transmits it to the management server 200. A plurality of different first threshold values and second threshold values corresponding to each other are stored, and the accumulated time of the load time is equal to or greater than the first threshold value or equal to or greater than the second threshold value corresponding to the position information received from the mixer vehicle 100. When it is determined, the replacement time information or the life time information may be generated.
　これによりミキサ車管理システムは、油圧ポンプが駆動しているときの位置（気温）に応じて高精度に交換時期を検知することができる。 This allows the mixer truck management system to detect the replacement time with high accuracy according to the position (temperature) when the hydraulic pump is driven.
　またこの場合、ミキサ車１００は、温度計を搭載している場合には、位置情報ではなく当該温度計が示す気温情報を管理サーバ２００へ送信し、管理サーバ２００は、当該気温情報に基づいて対応する第１閾値及び第２閾値を選択してもよい。 Further, in this case, when the mixer vehicle 100 is equipped with a thermometer, the temperature information indicated by the thermometer is transmitted to the management server 200 instead of the position information, and the management server 200 is based on the temperature information. Corresponding first and second threshold values may be selected.
　上述の実施形態においては、管理サーバ２００は、報知情報をミキサ車１００へ送信し、ミキサ車１００は、寿命時期報知情報を受信した場合、大音量のアラームを出力しＬＣＤ２２を点滅させた。この報知情報に加えて、または代えて、管理サーバ２００は、ミキサ車１００の機能の少なくとも一部を制限する機能制限信号をミキサ車１００へ送信してもよい。 In the above-described embodiment, the management server 200 transmits the notification information to the mixer vehicle 100. When the mixer vehicle 100 receives the life time notification information, the management vehicle 200 outputs a loud alarm and blinks the LCD 22. In addition to or instead of the notification information, the management server 200 may transmit a function restriction signal that restricts at least a part of the function of the mixer truck 100 to the mixer truck 100.
　例えば、油圧ポンプ５の寿命が到来している場合には、それを搭載したミキサ車１００もそれ以上運転させないのが好ましいが、ミキサドラム２に生コンが残留したままミキサ車１００の運転（すなわちミキサドラム２の回転）が停止してしまうと、生コンは固まってしまい無駄になってしまう。そこで、管理サーバ２００は、寿命時期情報が生成された場合には、ミキサドラム２への生コンのそれ以上の投入は規制するが排出は許可する投入制限信号をミキサ車１００へ送信し、ミキサ車１００はそれに基づき排出処理のみを実行してもよい。すなわち、この場合、排出モードから投入モードへの切替が禁止されることになる。 For example, when the life of the hydraulic pump 5 has come to an end, it is preferable not to further operate the mixer truck 100 on which the hydraulic pump 5 is mounted. If rotation stops, the ready-mixed food becomes solid and is wasted. Therefore, when the life time information is generated, the management server 200 transmits to the mixer vehicle 100 an input restriction signal that restricts the input of the live concrete to the mixer drum 2 but permits the discharge, to the mixer vehicle 100. May execute only the discharge processing based on the above. That is, in this case, switching from the discharge mode to the charging mode is prohibited.
　また、上記管理サーバ２００が上記制限信号を送信するのではなく、ミキサ車１００が、上記寿命時期報知信号の受信に基づいて、上記報知処理を実行すると共に、上記投入モードを自ら規制してもよい。 Further, the management server 200 does not transmit the limit signal, but the mixer vehicle 100 executes the notification process based on the reception of the life time notification signal and restricts the input mode by itself. Good.
　上述の実施形態では、ミキサ車１００の負荷時間情報生成部１１１が、上記圧力センサ５ａから受信される負荷圧力信号が所定値以上の吐出圧を示している場合に負荷時間情報を生成して管理サーバ２００へ送信していた。しかし、ミキサ車１００は、単に圧力センサ５ａの検知した吐出圧値を管理サーバ２００へ送信し、その圧力が所定値以上であるか否かの判断及び上記負荷時間情報の生成は、管理サーバ２００が実行してもよい。 In the above-described embodiment, the load time information generation unit 111 of the mixer vehicle 100 generates and manages load time information when the load pressure signal received from the pressure sensor 5a indicates a discharge pressure equal to or higher than a predetermined value. It was transmitted to the server 200. However, the mixer vehicle 100 simply transmits the discharge pressure value detected by the pressure sensor 5a to the management server 200, and determines whether the pressure is equal to or higher than a predetermined value and generates the load time information. May be executed.
