上述したシステムでは、移動体がトンネルや山間など、電波が届き難く無線通信が不可能な場所に移動した場合には、その間に取得された情報が車載器に蓄積され、当該移動体が無線通信可能な場所に移動したときにまとめて監視装置に送信される。 In the system described above, when a moving body moves to a place where radio waves are difficult to reach and wireless communication is not possible, such as a tunnel or a mountain, the information acquired during that time is accumulated in the on-board unit, and the moving body performs wireless communication. When it moves to a possible place, it is collectively sent to the monitoring device.

しかし、移動体が無線通信不可能な場所にある時間が長くなると、まとめて送信する情報が多量になり、送信時間が長くかかる。そのため、重要度の高い情報が監視装置で取得されるまでに時間がかかり、遠隔監視の精度が低下するという問題があった。 However, if the moving body stays in a place where wireless communication is not possible for a long time, a large amount of information to be collectively transmitted becomes large, and the transmission time becomes long. Therefore, there is a problem that it takes time for the monitoring device to acquire highly important information and the accuracy of remote monitoring is lowered.

The monitoring data is sequentially transmitted to the remote monitoring server, and when wireless communication with the remote monitoring server is impossible, the monitoring data generated by the monitoring data generation unit is adjusted according to the importance of the monitoring data. When it is detected that wireless communication with the remote monitoring server has changed from an impossible state to a possible state, the data having a high weighting value is prioritized and stored in the monitoring data storage unit. The monitoring data processing unit transmits the monitoring data stored in the monitoring data storage unit to the remote monitoring server.

また、本開示の移動体管理システムは、移動体に搭載された移動体管理装置と、前記移動体に無線接続され、前記移動体から遠隔地に設置された遠隔監視サーバとを備え、前記移動体管理装置は、所定時間間隔で前記移動体の監視データを生成する監視データ生成部と、前記監視データ生成部で生成された監視データを蓄積可能な監視データ蓄積部と、前記遠隔監視サーバとの無線通信が可能な状態のときには、前記監視データ生成部で生成された監視データを逐次前記遠隔監視サーバに送信し、前記遠隔監視サーバとの無線通信が不可能な状態のときには、前記監視データ生成部で生成された監視データに、当該監視データの重要度に応じた重み付けを行って前記監視データ蓄積部に蓄積させ、前記遠隔監視サーバとの無線通信が不可能な状態から可能な状態に移行したことを検知すると、前記重み付けの値が高いデータを優先して、前記監視データ蓄積部に蓄積された監視データを前記遠隔監視サーバに送信する監視データ処理部とを有することを特徴とする。 Further, the mobile body management system of the present disclosure includes a mobile body management device mounted on the mobile body and a remote monitoring server wirelessly connected to the mobile body and installed at a remote location from the mobile body. The body management device includes a monitoring data generation unit that generates monitoring data of the moving object at predetermined time intervals, a monitoring data storage unit that can store the monitoring data generated by the monitoring data generation unit, and the remote monitoring server. When wireless communication is possible, the monitoring data generated by the monitoring data generation unit is sequentially transmitted to the remote monitoring server, and when wireless communication with the remote monitoring server is not possible, the monitoring data The monitoring data generated by the generation unit is weighted according to the importance of the monitoring data and stored in the monitoring data storage unit, so that wireless communication with the remote monitoring server is possible from the impossible state.

When this is not possible, the generated monitoring data is weighted according to the importance of the monitoring data and stored in the monitoring data storage unit, and wireless communication with the remote monitoring server is not possible. When it is detected that the state has shifted to a possible state, the data having a high weighting value is prioritized, and the monitoring data accumulated in the monitoring data storage unit is transmitted to the remote monitoring server.

〈一実施形態による移動体管理システムの構成〉
以下に、一実施形態としての移動体管理システムの構成について、図１を参照して説明する。本実施形態による移動体管理システム１は、電車等の移動体１０に搭載された移動体管理装置としての車載器２０と、車載器２０に無線基地局３０およびネットワーク４０を介して無線接続された遠隔監視サーバ５０とを備える。 <Structure of mobile body management system according to one embodiment>

It is provided with a remote monitoring server 50.

移動体１０には、当該移動体１０内の機器、例えば燃料ポンプやエンジン等に関する複数の機器制御装置（第１機器制御装置１１−１、第２機器制御装置１１−２）と、無線基地局３０およびネットワーク４０を介して遠隔監視サーバ５０と無線通信を行う無線アンテナ１２と、これらの機器制御装置１１−１、１１−２および無線アンテナ１２に接続された車載器２０とが設置されている。図１においては、移動体１０に設置された第１機器制御装置１１−１および第２機器制御装置１１−２の２つの機器制御装置が車載器２０に接続された場合を示しているが、当該移動体１０内の機器に関するさらに多くの制御装置に接続されていてもよい。 The mobile body 10 includes a plurality of device control devices (first device control device 11-1, second device control device 11-2) related to devices in the mobile body 10, such as a fuel pump and an engine, and a radio base station. A wireless antenna 12 that wirelessly communicates with the remote monitoring server 50 via the 30 and the network 40, and an in-vehicle device 20 connected to these device control devices 11-1 and 11-2 and the wireless antenna 12 are installed. .. FIG. 1 shows a case where two device control devices of the first device control device 11-1 and the second device control device 11-2 installed on the moving body 10 are connected to the vehicle-mounted device 20. It may be connected to more control devices related to the device in the moving body 10.

車載器２０は、データ入力部２１と、監視データ生成部２２と、監視データ蓄積部２３と、通信制御部２４と、監視データ処理部２５とを有する。 The on-board unit 20 includes a data input unit 21, a monitoring data generation unit 22, a monitoring data storage unit 23, a communication control unit 24, and a monitoring data processing unit 25.

データ入力部２１は、第１機器制御装置１１−１および第２機器制御装置１１−２から、該当する機器の動作状況データを取得して車載器２０に入力する。監視データ生成部２２は、データ入力部２１から入力された動作状況データを加工して、当該移動体１０の動作を監視するための監視データを生成する。監視データ蓄積部２３は、監視データ生成部２２で生成された監視データを蓄積可能なメモリである。通信制御部２４は、無線基地局３０およびネットワーク４０を介して遠隔監視サーバ５０との無線通信を行う。 The data input unit 21 acquires the operation status data of the corresponding device from the first device control device 11-1 and the second device control device 11-2 and inputs the data to the vehicle-mounted device 20. The monitoring data generation unit 22 processes the operation status data input from the data input unit 21 to generate monitoring data for monitoring the operation of the moving body 10. The monitoring data storage unit 23 is a memory capable of storing the monitoring data generated by the monitoring data generation unit 22. The communication control unit 24 performs wireless communication with the remote monitoring server 50 via the wireless base station 30 and the network 40.

監視データ処理部２５は、通信制御部２４による遠隔監視サーバ５０との無線通信が可能な状態のときには、監視データ生成部２２で生成された監視データを通信制御部２４により遠隔監視サーバ５０に逐次送信させる。また、通信制御部２４による遠隔監視サーバ５０との無線通信が不可能な状態のときには、監視データ生成部２２で生成された監視データに、当該監視データの重要度に応じた重み付けを行って監視データ蓄積部２３に蓄積させる。また、遠隔監視サーバ５０との無線通信が不可能な状態から可能な状態に移行したことを検知すると、重み付けの値が高いデータを優先して、監視データ蓄積部２３に蓄積された監視データを通信制御部２４により遠隔監視サーバ５０に送信させる。 When the monitoring data processing unit 25 is in a state where wireless communication with the remote monitoring server 50 by the communication control unit 24 is possible, the monitoring data generated by the monitoring data generation unit 22 is sequentially transmitted to the remote monitoring server 50 by the communication control unit 24. Send it. When wireless communication with the remote monitoring server 50 by the communication control unit 24 is not possible, the monitoring data generated by the monitoring data generation unit 22 is weighted according to the importance of the monitoring data for monitoring. It is stored in the data storage unit 23. Further, when it is detected that the wireless communication with the remote monitoring server 50 has changed from the impossible state to the possible state, the data having a high weighting value is prioritized and the monitoring data stored in the monitoring data storage unit 23 is stored. The communication control unit 24 causes the remote monitoring server 50 to transmit data.

遠隔監視サーバ５０は、移動体１０を含む複数の移動体の車載器にネットワーク４０を介して接続され、これらの移動体から送信された監視データを取得して監視処理を行う。 The remote monitoring server 50 is connected to in-vehicle devices of a plurality of mobile bodies including the mobile body 10 via the network 40, acquires monitoring data transmitted from these mobile bodies, and performs monitoring processing.

〈一実施形態による移動体管理システムの動作〉
次に、本実施形態による移動体管理システム１の動作について、図２のフローチャートを参照して説明する。図２は、移動体管理システム１の稼動中に、監視対象の移動体１０の車載器２０で実行される処理を示す。 <Operation of mobile body management system according to one embodiment>
Next, the operation of the mobile body management system 1 according to the present embodiment will be described with reference to the flowchart of FIG. FIG. 2 shows a process executed by the vehicle-mounted device 20 of the mobile body 10 to be monitored while the mobile body management system 1 is in operation.

本実施形態において、移動体１０の移動動作中、第１機器制御装置１１−１および第２機器制御装置１１−２では、それぞれ該当する機器の動作状況データが所定時間間隔で取得され、車載器２０に送出される。車載器２０では、第１機器制御装置１１−１および第２機器制御装置１１−２から送出された動作状況データがデータ入力部２１から車載器２０に入力される。 In the present embodiment, during the moving operation of the moving body 10, the first device control device 11-1 and the second device control device 11-2 acquire the operation status data of the corresponding devices at predetermined time intervals, respectively, and the vehicle-mounted device. It is sent to 20. In the vehicle-mounted device 20, the operation status data transmitted from the first device control device 11-1 and the second device control device 11-2 is input to the vehicle-mounted device 20 from the data input unit 21.

車載器２０では、通信制御部２４により無線アンテナ１２を介して遠隔監視サーバ５０との無線通信が可能な状態であるときに（Ｓ１の「YES」）、データ入力部２１から動作状況データが入力されると（Ｓ２の「YES」）、監視データ生成部２２において当該動作状況データが加工され、当該移動体１０の動作を監視するための監視データが生成される（Ｓ３）。生成された監視データは、監視データ処理部２５により、通信制御部２４から無線アンテナ１２を介して遠隔監視サーバ５０に送信される（Ｓ４）。ステップＳ２〜Ｓ４の処理は、通信制御部２４により遠隔監視サーバ５０との無線通信が可能な状態である間、繰り返し実行される。 In the vehicle-mounted device 20, when the communication control unit 24 is in a state where wireless communication with the remote monitoring server 50 is possible via the wireless antenna 12 (“YES” in S1), the operation status data is input from the data input unit 21. When this is done (“YES” in S2), the operation status data is processed by the monitoring data generation unit 22, and monitoring data for monitoring the operation of the moving body 10 is generated (S3). The generated monitoring data is transmitted from the communication control unit 24 to the remote monitoring server 50 via the wireless antenna 12 by the monitoring data processing unit 25 (S4). The processes of steps S2 to S4 are repeatedly executed while the communication control unit 24 is in a state where wireless communication with the remote monitoring server 50 is possible.

そして、移動体１０がトンネル等の無線電波が届かない場所に移動し、遠隔監視サーバ５０との無線通信が不可能な状態になると（Ｓ１の「NO」）、再度無線通信が可能な状態になるまでの間（Ｓ５の「NO」）、監視データ処理に２５により、入力された動作状況データに基づいて生成された監視データについて（Ｓ６の「YES」、Ｓ７）、当該監視データの重要度が算出される（Ｓ８）。そして、算出された重要度に応じて重み付けされた監視データが監視データ蓄積部２３に蓄積される（Ｓ９）。 Then, when the mobile body 10 moves to a place such as a tunnel where wireless radio waves do not reach and wireless communication with the remote monitoring server 50 becomes impossible (“NO” in S1), wireless communication is possible again. Until then (“NO” in S5), the importance of the monitoring data generated based on the operation status data input by 25 in the monitoring data processing (“YES” in S6, S7). Is calculated (S8). Then, the monitoring data weighted according to the calculated importance is accumulated in the monitoring data storage unit 23 (S9).

監視データの重要度は、該当する監視データが当該移動体１０内における異常発生前後の所定時間内に取得されたデータ、または、所定時間内における変化率が所定値を超えたタイミング前後の所定時間内に取得されたデータに対し、高い値で算出される。ここで、異常発生の有無は、例えば、異常状態を検知すると鳴動するアラームの発報に基づいて判断される。 The importance of the monitoring data is the data acquired within the predetermined time before and after the occurrence of the abnormality in the moving body 10, or the predetermined time before and after the timing when the rate of change in the predetermined time exceeds the predetermined value. It is calculated with a higher value than the data acquired in. Here, the presence or absence of an abnormality is determined based on, for example, the issuance of an alarm that sounds when an abnormal state is detected.

また、移動体１０の監視データに関し、所定時間内における変化率が所定値を超えたときの一例を、図３（ａ）〜（ｃ）を参照して説明する。図３（ａ）は所定時間ごとの移動体１０の位置情報（監視データ）に基づいて取得された速度データ（一次微分データ）の経時的変化を示し、図３（ｂ）は当該速度データから生成された加速度データ（二次微分データ）の経時的変化を示し、図３（ｃ）は当該加速度データから生成された加速度の変化率データの経時的変化を示す。 Further, with respect to the monitoring data of the moving body 10, an example when the rate of change within a predetermined time exceeds a predetermined value will be described with reference to FIGS. 3A to 3C. FIG. 3A shows a change over time in the speed data (first-order differential data) acquired based on the position information (monitoring data) of the moving body 10 at predetermined time intervals, and FIG. 3B shows the speed data from the speed data. The time-dependent change of the generated acceleration data (secondary differential data) is shown, and FIG. 3C shows the time-dependent change of the acceleration change rate data generated from the acceleration data.

図３（ａ）〜（ｃ）は、車載器２０と遠隔監視サーバ５０とが無線通信可能な状態で、時刻ｔ0から車載器２０から遠隔監視サーバ５０に監視データの送信が開始され、時刻ｔ1に無線通信が不可能な状態になって監視データの蓄積が開始され、時刻ｔ5に無線通信が可能な状態になり監視データの送信が再開された場合のデータの変化を示している。 3 (a) to 3 (c) show that the on-board unit 20 and the remote monitoring server 50 can wirelessly communicate with each other, and the on-board unit 20 starts transmitting monitoring data from the on-board unit 20 to the remote monitoring server 50 at time t1. It shows the change in the data when the wireless communication becomes impossible and the accumulation of the monitoring data is started, the wireless communication becomes possible at time t5, and the transmission of the monitoring data is restarted.

ここで、時刻ｔ1からｔ5の間の時刻ｔ3に一時的に移動体１０の速度が急激に低下すると、加速度も急激に低下し、加速度の変化率が上昇する。上昇した加速度の変化率が所定値ｘを超えると、この時刻ｔ3を含む前後の時間帯である時刻ｔ2〜ｔ4内に取得された監視データに対し、他の時間帯（ｔ1〜ｔ2およびｔ4〜ｔ5）の監視データよりも高い値の重み付けが行われる。 Here, if the speed of the moving body 10 temporarily decreases sharply at time t3 between times t1 and t5, the acceleration also sharply decreases and the rate of change of acceleration increases. When the rate of change of the increased acceleration exceeds the predetermined value x, the monitoring data acquired within the time zones t2 to t4, which is the time zone before and after the time t3, is compared with other time zones (t1 to t2 and t4 to t4 to). Weighting of a value higher than the monitoring data of t5) is performed.

ここで、監視データ処理部２５は、変化率が所定値を超えたタイミングを、該当する監視データと、予め保持された正常時の複数データの分布群の重心との距離の指標値、例えばマハラノビス距離に基づいて認識するようにしてもよい。このような指標値を用いることにより、簡易に高い精度で、監視の重要度が高いタイミングを認識することができる。ステップＳ５〜Ｓ９の処理は、通信制御部２４により遠隔監視サーバ５０との無線通信が不可能な状態である間、繰り返し実行される。 Here, the monitoring data processing unit 25 sets the timing at which the rate of change exceeds a predetermined value as an index value of the distance between the corresponding monitoring data and the center of gravity of the distribution group of the plurality of data in the normal state held in advance, for example, Mahalanobis. It may be recognized based on the distance. By using such an index value, it is possible to easily recognize the timing of high importance of monitoring with high accuracy. The processes of steps S5 to S9 are repeatedly executed while the communication control unit 24 is in a state where wireless communication with the remote monitoring server 50 is impossible.

そして、移動体１０が無線電波が届く場所に移動し、通信制御部２４による遠隔監視サーバ５０との無線通信が可能な状態になると（Ｓ５の「YES」）、監視データ処理部２５により、監視データ蓄積部２３に蓄積されたデータがあるか否かが確認される。ここで、蓄積されたデータがあると判断されると（Ｓ１０の「YES」）、重み付けの値が高いデータおよび、重み付けの値が高いデータ以外で、取得された日時が所定のタイミングよりも古いデータが重要度が高いデータとして優先されて、蓄積された監視データが通信制御部から遠隔監視サーバ５０に送信される（Ｓ１１）。 Then, when the mobile body 10 moves to a place where the radio wave can reach and wireless communication with the remote monitoring server 50 by the communication control unit 24 becomes possible (“YES” in S5), the monitoring data processing unit 25 monitors. It is confirmed whether or not there is data stored in the data storage unit 23. Here, when it is determined that there is accumulated data (“YES” in S10), the acquired date and time is older than the predetermined timing except for the data having a high weighting value and the data having a high weighting value. The data is prioritized as the data of high importance, and the accumulated monitoring data is transmitted from the communication control unit to the remote monitoring server 50 (S11).

遠隔監視サーバ５０では、移動体１０の車載器２０を含む複数の移動体の車載器から送信された監視データが取得され、監視処理が行われる。 The remote monitoring server 50 acquires monitoring data transmitted from a plurality of vehicle-mounted devices of the mobile body including the vehicle-mounted device 20 of the mobile body 10, and performs monitoring processing.

以上の実施形態によれば、移動体が無線通信不可能な場所から無線通信可能な場所に移動した際に、当該移動体から遠隔地にある監視装置に対し、速やかに重要度の高い情報を無線送信することができる。 According to the above embodiment, when the mobile body moves from a place where wireless communication is not possible to a place where wireless communication is possible, information of high importance is promptly transmitted to the monitoring device located at a remote place from the moving body. It can be transmitted wirelessly.

上述した実施形態においては、移動体１０の車載器２０と遠隔監視サーバ５０との無線通信が不可能な状態である間、監視データが生成される都度、当該監視データについて重要度が算出され、該当する重み付けが行われて蓄積される場合について説明した。しかしこの処理には限定されず、生成された監視データを順次監視データ蓄積部２３に蓄積しておき、所定時間ごとに、蓄積された複数の監視データそれぞれに対する重要度を算出して重み付けを行うようにしてもよい。 In the above-described embodiment, the importance of the monitoring data is calculated each time the monitoring data is generated while the wireless communication between the vehicle-mounted device 20 of the mobile body 10 and the remote monitoring server 50 is impossible. The case where the corresponding weighting is performed and accumulated has been described. However, the processing is not limited to this, and the generated monitoring data is sequentially accumulated in the monitoring data storage unit 23, and the importance of each of the accumulated monitoring data is calculated and weighted at predetermined time intervals. You may do so.
