また表２は判定状態フラグの内容を示しており、ビットｂ０は各運行地点に割り当てられた格納場所のデータが有効か否かを示すフラグ、ビットｂ１は当該運行地点を中心とする所定範囲内に車輌が到着したか否かの判定を行うか否かを示すフラグ、ビットｂ２は当該運行地点を中心とする所定範囲内から車輌が離脱下か否かの判定を行うか否かを示すフラグである。
【００２８】
【表２】

【００２９】
このように、各運行地点の位置データに対応して判定状態フラグを設けており、判定状態フラグのビットｂ０，ｂ１，ｂ２のデータを書き換えることによって、各運行地点の位置データを到着又は離脱の判定用に使用するか否かを切り替えることができる。車輌の運行経路は毎回決まっておらず、１回運行する毎に運行中に通る運行地点が変わるため、到着又は離脱の判定に用いる運行地点の位置データをその都度設定する必要があるが、本実施形態では端末装置Ａに予め複数の運行地点の位置データを登録しており、運行時に管理センタＢから各位置データに対応して設けた判定状態フラグのビットｂ０，ｂ１，ｂ２を書き換えることで、到着又は離脱の判定に用いる運行地点の位置データを選択しているので、その都度位置データを設定する必要がなく、送信データのデータ量を少なくできる。
【００３０】
また、上述した記憶装置１９には、運行地点の位置データ以外にも端末装置Ａの動作を設定するための複数のパラメータが、各パラメータに割り当てられた格納場所（アドレス）にそれぞれ記憶されている。複数のパラメータは、表３および表４に示すように１４個のパラメータ群に分けられ、各パラメータ群に対して１番〜１４番の登録番号が設定されている。

【００３３】
ここで、運行地点の設定と同様、管理センタＢから各車輌の端末装置Ａに対して各パラメータのデータを無線伝送路を通して伝送しており、端末装置Ａが管理センタＢから受信した各パラメータのデータを記憶装置１９に記憶させることで、現地に行くことなく各パラメータのデータを登録することができる。パラメータの設定時には、管理コンピュータ３０が、無線制御部３２及び無線装置３１からなる第２の通信手段を通じて、１乃至複数のパラメータのデータの前に、伝送するパラメータに割り当てられた登録番号を指定するための２バイトの登録番号指定情報Ｄ２１，Ｄ２２を付加した送信データを端末装置Ａへ送信させている。
【００３４】
図８及び図９（ａ）に示すように、登録番号指定情報Ｄ２１，Ｄ２２はそれぞれ８ビットのデータからなり、登録番号指定情報Ｄ２１の左側のビットを最下位ビット、登録番号指定情報Ｄ２２の右側のビットを最上位ビットとし、最下位ビットから順番に１番から１４番までの登録番号を示している。そして、登録番号指定情報Ｄ２１，Ｄ２２の各ビットが１の場合はその登録番号に対応するパラメータのデータが付加されていることを示し、０の場合はパラメータのデータが付加されていないことを示している。例えば図９（ｂ）に示す例では登録番号指定情報Ｄ２１の１番目および５番目のビット、登録番号指定情報Ｄ２２の４番目（登録番号指定情報Ｄ２１の１番目のビットから数えて１２番目）のビットが１となっているので、登録番号指定情報Ｄ２１，Ｄ２２の後に続けて、登録番号が１而して、端末装置Ａのマイコン１０には、無線制御部２１及び無線装置２０を通じて登録番号指定情報Ｄ２１，Ｄ２２とパラメータのデータとが入力されるから、マイコン１０では登録番号指定情報Ｄ２１，Ｄ２２の各ビットから伝送されたパラメータの登録番号を読み取り、記憶装置１９の対応する格納場所に各パラメータのデータを書き込むことができる。
【００３５】
このように、本実施形態では管理センタＢから端末装置Ａにパラメータのデータを伝送する際に、伝送するパラメータに割り当てられた登録番号を指定する登録指定情報を同時に送信しているので、登録指定情報の示す格納場所に伝送されたパラメータのデータを書き込むことができ、したがって設定作業を行いたいパラメータのみを伝送すればよく、全てのパラメータのデータを送信する必要がないから伝送するデータ量を少なくでき、通信コストを低減することができる。
【００３６】
なお、端末装置Ａの記憶装置１９や管理コンピュータ３０の記憶装置（図示せず）には、それぞれ、伝送するデータを圧縮用のテーブルにしたがって圧縮し、そのデータ量を小さくする圧縮プログラムや、圧縮した状態で伝送されたデータを展開（解凍）して元のデータサイズに復元する解凍プログラムが組み込まれており、端末装置Ａと管理コンピュータ３０との間で運行地点の位置データやパラメータを送信する際にはデータを圧縮した状態で送信しているので、データ量を少なくして通信コストを低減することができる。なお、圧縮プログラムや解凍プログラムには周知の汎用プログラムを使用すればよい。

しかも、種別コードデータを全指定コード、個別指定コード、又は範囲指定コードに設定することで、全ての運行地点のポイント番号を一度に指定したり、各運行地点のポイント番号を個別に指定したり、連続するポイント番号を範囲で指定することができるという効果がある。

The terminal device receives the transmission data transmitted from the management center, and writes the parameter data corresponding to the storage location indicated by the registration number designated by the registration number designation information. When transmitting parameter data to the device, the registration specification information that specifies the registration number assigned to the parameter to be transmitted is the same. Since the parameter data transmitted to the storage location indicated by the registration designation information can be written, only the parameter to be set needs to be transmitted, and it is not necessary to transmit all the parameter data. The amount of data to be transmitted can be reduced and the communication cost can be reduced.
[0009]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
The vehicle operation management system of the present embodiment is configured as shown in FIG. 1, and the terminal device A mounted on the vehicle receives a radio wave emitted from a GPS satellite by the GPS antenna 11, and then serves as a positioning means. The current position information is converted by the GPS engine 12 and is taken into a microcomputer (hereinafter abbreviated as a microcomputer) 10. The microcomputer 10 also captures vehicle state information from various sensors 13 provided for monitoring the vehicle state (for example, vehicle speed and door open / closed state) via the sensor interface (sensor I / F) 14. In response to a request from the management computer 30, information is transmitted to the management center B side through the wireless transmission path by the first communication means including the wireless control unit 21 and the wireless device 20. Here, a program (application program) for defining the processing contents of the terminal device A and various parameters are stored in the storage device 19 as storage means. Further, the terminal device A has a memory card interface (abbreviated as a memory card I / F) 16 for connecting an IC card 15 as a memory card, and an external interface for connecting a personal digital assistant (PDA) 17 ( (Abbreviated as external I / F) 18 is provided.
[0011]
On the other hand, on the management center B side, information can be exchanged between the management computer 30 and the terminal device A through the wireless device 31 and the wireless control unit 32, and the above request command is transmitted to the terminal device A. Or the current position information and vehicle status information from the terminal device A can be received. The management computer 30 is realized by a personal computer equipped with appropriate software, and the management computer 30 constitutes management means.
[0012]
By the way, in the storage device 19 of the terminal device A, position data (longitude and latitude data) of a plurality of (for example, 50) operation points of the vehicle can be registered, and the operation points registered in the storage device 19 can be registered. Of these, the microcomputer 10 is a means for determining whether or not the vehicle has reached the operating point based on the position data of one or more operating points that pass during the current operation and the current position of the vehicle determined by the GPS engine 12. Can be determined. In addition, the point number which shows the storage place in the memory | storage device 19 is allocated to the position data of each operation point, and the position data of the operation point corresponding to the storage place which the point number shows are stored.
[0013]
Here, in this embodiment, the location data of the operating point is transmitted from the management center B to the terminal device A of each vehicle through the wireless transmission path, and the position of each operating point received by the terminal device A from the management center B. By storing the data in the storage device 19, it is possible to register the position data of each operation point without going to the site, and the usability of the vehicle operation management device is improved.
[0014]
Below, the procedure which sets the position data of an operation point with respect to the terminal device A from the management center B is demonstrated. At the time of setting the position data, the management computer 30 transmits the position data of one or more operation points and the points assigned to the one or more operation points through the second communication means including the wireless control unit 32 and the wireless device 31. Transmission data including point designation information for designating a number is transmitted to the terminal device A. At this time, the transmission data transmitted from the management center B through the wireless control unit 21 and the wireless device 20 is input to the microcomputer 10 of the terminal device A, and the microcomputer 10 as the writing means is designated by the point designation information in the transmission data. The location data of each operation point is written in the storage location of the storage device 19.
[0015]
Thus, in this embodiment, when transmitting the location data of the operating point from the management center B to the terminal device A, the point specifying information assigned to the operating point to be transmitted is simultaneously transmitted. It is possible to write the position data transmitted to the indicated storage location, and therefore, it is only necessary to transmit the operating point where the setting work is to be performed, and it is not necessary to transmit the data of all the operating points, so the amount of data transmitted can be reduced Communication costs can be reduced.
[0016]
By the way, the above-described point designation information is configured by adding an 8-bit processing code CD in front of number data representing the point number itself in binary. As shown in FIG. 2A, the processing code CD includes number information data CD1 indicating the number of number data added after the processing code CD as upper 4 bits and type code data CD2 indicating a method of designating a point number. The lower 4 bits are used. 2 to 9, the left side of each bit string is shown as the lower bit and the right side as the upper bit.
[0017]
In the point designation information shown in FIG. 2 (b), the type code data CD2 is set to 0 (0000). In this case, the first to 50th bits each have 50 operation points instead of the number data. Since the point number is designated by adding 7-byte point data D1 to D7 corresponding to the point number, the number information data CD1 becomes 0 (0000). Then, after this point designation information, transmission data to which position data of each operation point is added in order is transmitted from the management center B. The numbers in parentheses indicate each data in binary, with the left bit being the lower bit and the right bit being the upper bit.
[0018]
Each bit of the point data D1 to D7 indicates the point number Nos. 1 to 50 in order from the lower bit (the left bit in the figure), and the first bit of the first point data D1 (this bit is the least significant bit) Corresponds to the first point number, and the fourth bit of the third point data D3 (the 20th bit counted from the least significant bit) corresponds to the 20th point number. The sixth bit of D4 (the 30th bit counted from the least significant bit) corresponds to the 30th point number. When each bit is 1, it indicates that position data of the operating point corresponding to the point number is added, and when it is 0, it indicates that no position data is added. In this embodiment, the case where the number of operation points is 50 is described as an example, so the third bit to the eighth bit of the point data D7 (the 51st bit to the 56th bit counted from the least significant bit) Up to this is an undefined area.
[0019]
As described above, when the type code data CD2 is “0”, the point number to be transmitted is directly specified by the 7-byte point data D1 to D7 following the processing code CD, and therefore specified by the point data D1 to D7. It is possible to transmit and register only the position data of the operation point corresponding to the point number, and to transmit only the position data to be registered, so that the amount of transmission data can be reduced and the communication cost can be reduced.
[0020]
By the way, as a method for designating the point number, in addition to the method for designating the point number using the 7-byte point data D1 to D7 as described above, individual designation for individually designating the point number, from what number to what number There are methods such as range designation that designates consecutive point numbers up to, all designation that designates all point numbers, etc., and individual designation when type code data CD2 is “1”, and designation when “2” The range designation is “3”, indicating all designations.
[0021]
Here, a procedure for designating a point number by each designation method will be described. First, a procedure for designating a point number by an individual designation method will be described with reference to FIGS. In the case of individual designation, the type code data CD2 of the processing code CD is set to 1 (1000), and number information data CD1 indicating the number of number data is added to the type code data CD2. In the example shown in FIG. 3, the number information data CD1 is 1 (1000) because the number data D11 (01001000) representing the binary number of the 50th point number itself is added after the processing code CD. The code CD is (10001000). In the example shown in FIG. 4, since the number data D12 to D14 indicating the 50th, 1st and 15th point numbers are added after the processing code CD, the number information data CD1 is 3 ( As a result, the processing code CD is (10001100). As described above, when the type code data CD2 is “1” (individual designation), the number data is added by the number of point numbers to be transmitted after the processing code CD. For example, since the data amount of the point designation information is within 7 bytes, the data capacity of the point designation information can be reduced as compared with the case where the type code data CD2 is set to “0”.
[0022]
Next, a procedure for designating the point number by the range designation method will be described with reference to FIGS. When the range is designated, the type code data CD2 of the processing code CD is set to 2 (0100), and the number information data CD1 indicating the number of number data is added to the type code data CD2.
[0023]
FIG. 5 shows point designation information when a range of point numbers from 35 to 50 is designated. Two pieces of number data D15 representing the point numbers 35 and 50 themselves in binary numbers after the processing code CD. Since D16 is added, in this case, the data is 3 bytes. In the case of range designation, since a set of number data indicating the range is counted as one, the number information data CD1 is 1 (1000), and as a result, the processing code CD is (01001000). In addition, the example shown in FIG. 6 shows point designation information when the range of point numbers from 35 to 50 and point numbers from 3 to 10 are collectively designated, and 35 after the processing code CD. Since number data D17 to D20 each representing the point number of No. 50, No. 3, No. 3 and No. 10 in binary numbers are added, the point designation information is 5-byte data. In this case, since the number information data CD1 is 2 (0100), the processing code CD is (01000100). Therefore, when the type code data CD2 is “2” (range specification), a plurality of pairs of point numbers specifying the range are added after the processing code CD. Since the data amount of information is within 7 bytes, the data capacity of the point designation information can be reduced as compared with the case where the type code data CD2 is set to “0”.
[0024]
Finally, a procedure for designating a point number by the whole designation method will be described with reference to FIG. In the case of all designation, the type code data CD2 of the processing code CD is 3 (1100), and since all point numbers are designated, no number data is added after the processing code CD, so the number information data CD1 is 0 (0000). ), The processing code CD is (11000000).
[0025]
By the way, as shown in Table 1, the position data of each operating point stored in the storage device 19 is the sum of the 2-byte data of the determination status flag, the 4-byte data indicating the latitude, and the 4-byte data indicating the longitude. It consists of 10 bytes of data.
[0026]
[Table 1]

[0027]
Table 2 shows the contents of the determination state flag, bit b0 is a flag indicating whether or not the data of the storage location assigned to each operation point is valid, and bit b1 is within a predetermined range centering on the operation point. A flag indicating whether or not the vehicle has arrived at a bit, bit b2 is a flag indicating whether or not to determine whether or not the vehicle is leaving within a predetermined range centered on the operating point It is.
[0028]
[Table 2]

[0029]
Thus, the determination state flag is provided corresponding to the position data of each operation point, and the position data of each operation point is arrived or departed by rewriting the data of bits b0, b1, b2 of the determination state flag. It is possible to switch whether or not to use for determination. The operation route of the vehicle is not decided every time, and the operation point that passes during operation changes every time it is operated. In the embodiment, position data of a plurality of operation points is registered in the terminal device A in advance, and the bits b0, b1, b2 of the determination state flag provided corresponding to each position data from the management center B during operation are rewritten. Since the position data of the operation point used for the determination of arrival or departure is selected, it is not necessary to set the position data each time, and the data amount of the transmission data can be reduced.
[0030]
In addition, the storage device 19 described above stores a plurality of parameters for setting the operation of the terminal device A in addition to the location data of the operating point, in the storage locations (addresses) assigned to the respective parameters. . The plurality of parameters are divided into 14 parameter groups as shown in Tables 3 and 4, and registration numbers 1 to 14 are set for each parameter group.
[0031]
[Table 3]

[0032]
[Table 4]

[0033]
Here, similarly to the setting of the operating point, data of each parameter is transmitted from the management center B to the terminal device A of each vehicle through the wireless transmission path, and each parameter received by the terminal device A from the management center B is transmitted. By storing the data in the storage device 19, the data of each parameter can be registered without going to the site. At the time of parameter setting, the management computer 30 designates a registration number assigned to the parameter to be transmitted before the data of one or more parameters through the second communication means including the wireless control unit 32 and the wireless device 31. The transmission data to which the 2-byte registration number designation information D21, D22 is added is transmitted to the terminal device A.
[0034]
As shown in FIGS. 8 and 9A, the registration number designation information D21 and D22 are each composed of 8-bit data. The left bit of the registration number designation information D21 is the least significant bit, and the right side of the registration number designation information D22. Are the most significant bits, and the registration numbers from 1 to 14 are shown in order from the least significant bit.
