[0007]

Embodiments of the present invention will be described below with reference to the drawings. A: Configuration of Embodiment A-1: Overall Configuration FIG. 1 is a diagram showing an overall configuration of a mobile body repair system to which a mobile body repair method according to an embodiment of the present invention is applied. For this reason, only one vehicle 1 is illustrated as a vehicle for which a failure is to be detected. In the figure, 2 is a mobile communication network, 3 is a location service center connected to the mobile communication network 2, and each vehicle communicates with the location service center 3 via the mobile communication network 2. Reference numeral 4 denotes a repair service center connected to the location service center 3, which provides a repair service for a corresponding vehicle based on information supplied from the location service center 3.

In the vehicle 1, reference numeral 11 denotes a failure detection device incorporated in the vehicle 1, which detects the behavior, temperature, etc. of each part of the vehicle 1. If the detection result is abnormal, the abnormal location and the degree of abnormality ( (For example, temperature).
Reference numeral 12 denotes a PDA (Personal Digital Assistant) mounted on the vehicle 1;
Reference numeral 3 denotes a mobile device corresponding to the mobile communication network 2, and a PDA 12
Controls the failure detection device 11 and the mobile device 13 and is activated when any event occurs during the suspension.

Here, the configuration of the PDA 12 is shown in FIG.
As shown in this figure, the PDA 12 includes a GPS receiver 121 for receiving signals from satellites, a display panel 122 such as a liquid crystal panel, an instruction input device 123 such as a touch panel, and
PU (Central Processing Unit), ROM (Read Only Memory),
The control unit 124 includes a RAM (Random Access Memory) and various I / O interfaces. The control unit 124 executes the program stored in the ROM
Is executed in response to an event, so that G inside the PDA 12 is
The PS receiver 121 and the display panel 122, the external failure detection device 11 and the mobile device 13 are controlled to perform a failure detection process described later.

Referring again to FIG. 1, the location service center 3
Includes a GPS receiver 31 having the same configuration as that of the GPS receiver 121, responds to an incoming call request from the mobile communication network 2, receives information from the vehicle supplied via the mobile communication network 2, and receives a signal from the GPS receiver 31. And the information based on the connection state with the vehicle side to the repair service center 4 and
The information from the repair service center 4 is transferred to the vehicle.

A-2: Processing Performed by Control Unit 124 Next, the failure detection processing performed by the control unit 124 of the PDA 12 will be described with reference to FIG. FIG. 3 shows processing when an alarm signal is output from the failure detection device 11 (abnormal processing).
Is a flowchart showing the flow of the process.
The DA 12 is shifted from the suspend state to the operating state, and first, a call instruction and a connection destination telephone number stored at a predetermined address in the RAM are supplied to the mobile device 13 (step SA).
1). As a result, the mobile device 13 makes a call using the connection destination telephone number, and establishes a line with the location service center 3.

[0014] Further, following step SA1 (or in parallel with step SA1), the control unit 124 controls the GPS.
The position information output from the receiver 121 is received (step SA2), and transmitted from the mobile device 13 to the position service center 3 together with the identification information of the vehicle 1 and an alarm signal (step SA3). In the present embodiment, the vehicle 1
Although the identification number of the vehicle 1 can be arbitrarily set by the driver of the vehicle 1, it is needless to say that the identification number needs to be set so as not to be duplicated. Further, if the identification number of the mobile device 13 is used as the identification number of the vehicle 1, the information transmitted from the mobile device 13 to the location service center 3 in step SA2 may be only the location information of the vehicle 1 and the alarm signal. . Then, the control unit 124 controls the position service center 3
Receiving the waiting time transmitted from the
2 to the driver (step SA4), and the mobile device 1
3 to disconnect the line (step SA5).

A-3: Processing Performed by Location Service Center 3 at the Time of Incoming Call The location service center 3 performs the processing shown in FIG. 4 when an incoming call is received from the mobile communication network 2. That is, at the time of an incoming call, the location service center 3 determines whether or not the calling number included in the incoming call request from the mobile communication network 2 is the number of the mobile device owned by the location service contractor (step SB).
1) If the result of this determination is "NO", the call is rejected and the process is terminated (step SB2). Conversely, if the result of the determination is "YES", incoming calls are permitted (step S).
B3). As a result, a line is established with the mobile device 13. The telephone number of the location service contractor is registered in the location service center 3 at the time of contract.

Next, when the identification information, the position information, and the alarm signal are transmitted from the mobile device 13 via the line,
These are received (step SB4), and the position information and G
The position of the vehicle 1 is specified based on the received signal of the PS receiver 31 (step SB5). That is, in the present embodiment, the position of the vehicle is specified by a known method using two GPS receivers in order to increase the accuracy. Of course, when sufficient accuracy can be obtained only by the GPS receiver 121 on the vehicle 1 side, the GPS receiver 31 on the position service center 3 side may be omitted. Further, the position is not determined on the vehicle 1 side but is determined on the position service center 3 by the vehicle 1 (that is, the PDA 1).
In order to reduce the burden on 2), if the vehicle 1 has sufficient arithmetic processing capability, the vehicle 1 may obtain a position and transmit this to the position service center 3. . Next, the location service center 3 transmits the location specified in step SB5, the identification information, the alarm signal, and the calling number to the repair service center 4 (step SB5).
6) In response, the waiting time supplied from the repair service center 4 is transferred to the vehicle 1 (step SB).
7).

A-4: Processing Performed by the Repair Service Center 4 When the repair service center 4 is supplied with information from the location service center 3, first, as shown in FIG. The position and the alarm signal of No. 1 are stored in association with the identification number and the reception time (step SC1), and the contents of the alarm signal (the abnormal part and the abnormal degree) are associated with the abnormal part and the abnormal degree and the repair member. By referring to the database (repair member correspondence database), a list of repair members for coping with the failure represented by the alarm signal is presented to the monitor together with the identification number, the position, and the content of the alarm signal (step SC2). Further, the repair service center 4 refers to the repair member database (repair member inventory database) stored in the facility and allocates the repair member specified in step SD2 (step SC3). And
The waiting time input by the monitor is transmitted to the vehicle 1 via the position service center 3 (step SC4).

B: Operation of Embodiment Next, the operation of the embodiment having the above-described configuration will be described. However, it is assumed that the driver of the vehicle 1 has concluded a contract for using the position service center 3 in advance. When the driver of the vehicle 1 mounts the mobile device 13 at a predetermined position in the vehicle 1, the mobile object repair system becomes operable.
In this situation, if the failure detection device 11 does not detect any abnormality, no alarm signal is output, and therefore, the PD
A12 and the mobile device 13 remain in the suspended state. Conversely, if any part of the vehicle 1 fails and the failure detection device 11 detects an abnormality in the vehicle 1, an alarm signal is output from the failure detection device 11. This allows PDA
12 is activated, the position information obtained by the GPS receiver 121, the identification information of the vehicle 1, and the above-mentioned alarm signal
3 is transmitted to the location service center 3, and the location of the vehicle 1, identification information, and an alarm signal are supplied to the repair service center 4.

At the repair service center 4, repair members required for repair are presented to the supervisor based on the contents of the alarm signal, and the position of the vehicle 1 is presented. Thus, the monitor notifies the worker of the position of the vehicle 1 and instructs the operator to prepare necessary repair members. further,
The monitor calculates the required time to arrive at the site (that is, the waiting time) based on the presented repair members and the position of the vehicle 1 and inputs the calculated time to the repair service center 4. This waiting time is transferred to the vehicle 1 and notified to the driver of the vehicle 1. In the repair service center 4, the database of the repair members stored in the facility is automatically updated by the above allocation.

C: Supplement In the above-described embodiment, the PDA 12 disconnects the line after receiving the waiting time. However, the line is connected until the worker arrives, and the position information and the alarm signal are transmitted to a predetermined location. You may make it transmit repeatedly at time intervals. At this time, if the position information and the alarm signal are transferred from the repair service center 4 to the vehicle used by the worker, the worker can go to the site while checking the latest information.

If the telephone number of the mobile unit 13 is transferred from the location service center 3 to the repair service center 4, the supervisor or the worker of the repair service center 4 can operate the vehicle 1 as necessary. You can make a voice call with a person. Further, a database may be provided in the repair service center 4 which stores the current position of each worker and the repaired members being carried, and the repair may be efficiently performed with reference to this database. in this case,
The time required for the work of each worker may be a time predicted in advance or a time based on a report from a worker at the site. With this configuration, even when a repair member that is out of stock in the facility is requested, there is a high possibility that it is not necessary to take out a tow truck.

Further, in the repair member correspondence database, a member which cannot be completely repaired but is effective as a substitute member is also registered so as to avoid a prolonged waiting time due to lack of stock of repair members and dispatch of a tow truck as much as possible. You may. Further, the vehicle 1 detects failure sign information indicating a failure sign of the vehicle and transmits the same. The sign database indicating the correspondence between the failure sign information and the repaired member is provided in the repair service center 4. It may be used to prepare for a failure in the near future. In particular, if the time until the failure can be determined to some extent accurately, not only the repair member is allocated in advance, but also the failure will occur based on the change in the position of the vehicle 1 and the time until the failure. It is also possible to find a point and arrange a worker with sufficient repair members near the point.
Of course, the vehicle 1 may be inspected before failure.

Needless to say, the mobile unit 13 may be irremovably attached to the vehicle 1 or a PDA.
12 may be detachably attached to the vehicle 1. If the mobile communication network 2 is a CDMA mobile communication network, the position of the mobile device 13 in the mobile communication network 2 can be specified with sufficiently high accuracy. Therefore, in this case, the GPS receiver need not be used. Further, in the present invention, the object of the repair is a moving object, and it is needless to say that the object is not limited to the vehicle.

[0022]

As described above, according to the present invention,
At a remote location, the position of a moving object that has failed (or has a sign of failure) and the repair members required for repair can be quickly and accurately grasped.
