Mounted on the vehicle (taxi) is determined using GPS (Global Positioning System). Mobile station itself is detected and stored by the positioning system). Then, each mobile station 1a, 1b,... Returns position dynamics information to / from the base station 2 in a dedicated transmission slot assigned to each vehicle number based on a periodic polling signal from the base station 2. . The base station 2 polls all the mobile stations in order and grasps the position dynamic information of all the mobile stations 1a, 1b,. It should be noted that there is at least one base station 2 and is connected to a management center 4 using the AVM system 3. The management center 4 uses the location dynamic information of the mobile stations 1a, 1b,. Car search for optimal vehicle and dispatch taxi vehicle. On the other hand, for a staying mobile station that repeats waiting for a customer without traveling, the manager in charge of the management center 4 checks the position and dynamics of the mobile station on the terminal screen in the AVM system 3 and travels by voice. Warning.

  Also, in a corporate taxi company, the taxi crew has a fixed day break time, and when the crew member wants to take a break, he presses the break button provided on the mobile station terminal and sets the mobile station's dynamics as a break. I am going to take a break. For the management of such taxi crew break times, the manager in the management center 4 confirms and measures the location and dynamics of the mobile station on the terminal screen in the AVM system 3, and the break time is longer than the specified time. The station is notified by voice that the break has ended.

Further, as a known technique related to the present invention, in a wireless mobile communication system including a base station and a plurality of mobile stations, the plurality of mobile stations transmit position information acquired by GPS to the base station, and the base station is transmitted. A technique is known that monitors whether the location information of a mobile station stays at a place where waiting is prohibited, and gives a warning instruction to the corresponding mobile station when the predetermined time remains at the place where waiting is prohibited (For example, refer to Patent Document 1).

  In a conventional taxi dispatch system, the management center 4 uses a GPS system or polling data transmission technology to search for an optimal mobile station (vehicle) according to the customer's current location information, and also transmits the dispatch information in characters, etc. By doing so, the operation efficiency is improved, and customer service is improved by arriving at the customer earlier.

  On the other hand, in order to increase the operating revenue, it is necessary to acquire free customers by running not only wireless dispatch but also mobile stations. For this reason, the person in charge of the management center 4 confirms on the terminal screen of the AVM system 3 and notifies by voice so that the mobile station does not stay.

  However, in the conventional method in which the manager in charge confirms the staying mobile station on the terminal screen of the AVM system 3, there is a risk of human error such as omission of confirmation. There are cases where it is not possible.

  In addition, when managing the rest time of taxi crew in the management center 4, as in the case of managing the staying mobile station, the manager in charge of the management center 4 displays the mobile station on the terminal screen in the AVM system 3. The state is confirmed by visual observation, and the mobile station is notified by voice that the break time is over to the mobile station whose break time is longer than the specified time.

  However, in the method in which the manager in charge visually confirms the status of the mobile station on the terminal screen as described above, there was a human error such as forgetting to take a break for the taxi crew or omission of confirmation by the manager in the management center 4. In this case, there is a problem that labor management becomes impossible.

  The present invention has been made to solve the above-described problem, and can detect a stagnant mobile station and automatically notify a warning message, prevent occurrence of a human error, and reliably manage the mobile station. An object of the present invention is to provide a vehicle dispatch processing system that can perform the above.

  In addition, the present invention can automatically detect an excess of the break time on the management center side and notify a warning message when the crew of the mobile station continues to take a break beyond a certain time, thereby ensuring labor management of the crew. It is an object of the present invention to provide a vehicle dispatch processing system that can be used.

  A first invention is a mobile station that transmits a vehicle number and positional dynamic information of the host vehicle by a wireless device, and collects positional dynamic information from the mobile station via a base station by polling and moves vehicle allocation information to the mobile station. A dispatching processing system comprising a management center that transmits to a station and processes the dispatching, wherein the management center measures the residence duration of each mobile station from the location and dynamic information of each mobile station, A warning notification is made to a mobile station staying in excess of the distance, and a vehicle allocation target is selected based on the staying continuation time of each mobile station.

  According to a second aspect of the present invention, there is provided a mobile station for transmitting position dynamic information including a vehicle number of a host vehicle and a break start and release notification by a wireless device, and positional dynamic information from the mobile station by polling via a base station. A vehicle dispatch processing system configured to collect and transmit vehicle dispatch information to the mobile station and perform the vehicle dispatch process, the management center including a start of a break included in the location dynamic information of each mobile station and The break time of each mobile station is measured by the release notification, and a warning is notified to the mobile station that continues the break beyond a certain time.

  According to a third aspect of the present invention, in the dispatch processing system according to the second aspect of the invention, when the management center issues a warning notification to the mobile station that continues the break over a certain time, the warning is ignored and the break is continued. It is characterized in that the break state is forcibly released by performing a break release notification to the mobile station.

  According to the present invention, the management center manages position information and dynamic information transmitted from the mobile station in real time by the wireless communication system, performs automatic warning, and selects candidate vehicles, thereby causing human error and notification. It is possible to eliminate the delay.

  In addition, the management center manages the break time of the mobile station, warns the mobile station that has been taking a break for a certain period of time, and is forced to ignore the warning and continue the break.

FIG. 3 is a conceptual diagram in the case of automatically notifying a stay vehicle of a stay warning in the first embodiment.
In FIG. 3, 11, 12, and 13 are mobile stations that are currently traveling, and 14 is a mobile station that is staying. Each of the mobile stations 11 to 14 always transmits position dynamic information indicating the current position and dynamics to the management center 20 based on a periodic polling signal from the base station 21. The management center 20 includes a vehicle management information database 201, communicates with the mobile stations 11 to 14 via the base station 21 by the AVM system 202, collects position dynamic information of the mobile stations 11 to 14, Stored in the management information database 201.

  Next, the processing operation when the management center 20 specifies the mobile station 14 in the staying state and automatically notifies the staying warning will be described with reference to the flowcharts shown in FIGS.

  Each of the mobile stations 11 to 14 detects and stores the current position by the GPS satellite 26, and transmits position dynamic information A to the management center 20 according to a periodic polling signal from the base station 21, as shown in FIG. To do.

  When the management center 20 receives the position dynamic information A sent from each mobile station 11 to 14 (step A1), the management center 20 stores the received position dynamic information in the vehicle management information database 201 (step A2). And the staying state and staying continuation time of each mobile station 11-14 are measured by the said positional information and dynamic information (step A3), and it is judged whether it is staying (step A4). If it is not staying, the process returns to step A1, but if it is determined that it is staying, it is determined whether or not the staying duration exceeds a predetermined time (step A5). If it does not exceed the set time, the process directly returns to step A1.

  Here, for example, when the staying time of the mobile station 14 exceeds the set time, the management center 20 transmits a warning message (or alarm) B indicating that it is in a staying state to the mobile station 14 (step). A6). As shown in FIG. 2, the mobile station 14 receives the warning message sent from the management center 20 by the digital radio 42 and outputs it to the operation display 41. The operation indicator 41 displays a warning message on the display unit 411 by the information processing unit 413, and further notifies the crew member by a warning light, an alarm sound, or the like as necessary.

  The crew member of the mobile station 14 confirms that the staying continuation time has become longer than a predetermined time by the warning message, and runs the vehicle.

  Even if the management center 20 transmits a warning message to the mobile station in the staying state, the management center 20 may send the warning message again if the mobile station continues to stay.

  Further, the management center 20 searches for an optimal mobile station (vehicle) when a customer requests a vehicle allocation. At this time, the mobile station with a short residence duration is preferentially set as a vehicle allocation target.

  FIG. 5 is a conceptual diagram when the management center 20 selects a dispatch target in consideration of the residence duration of the mobile station.

  When the management center 20 receives the position dynamic information A sent from each of the mobile stations 11 to 14, the management center 20 checks the information in the vehicle management information database 201 by the AVM system 202 to grasp the mobile station that is staying, and The duration time is calculated and stored in the vehicle management information database 201.

Then, the management center 20 automatically selects the mobile station with the shortest residence time from the mobile stations 11 to 14 that satisfy certain conditions automatically by the AVM system 202 when the customer places an order for wireless dispatch. To do. Now, for example, as shown in FIG. 5, when a mobile station 11-14 meets a certain condition when an order for wireless dispatch is received from a customer,
Residence time of mobile station 11 is 40 minutes,
Residence time of mobile station 12 is 50 minutes,
Residence time of mobile station 13 is 80 minutes,
The residence time of the mobile station 14 is 120 minutes,
If so, the mobile stations 11 with the shortest residence continuation time are narrowed down, and the dispatch information C is transmitted from the management center 20 to the mobile stations 11.

  Among the mobile stations 11 to 14 that satisfy certain conditions as described above, the mobile station 11 with the shortest staying continuation time acquires the dispatch information C and heads for the customer.

  As shown in the first embodiment, the management center 20 manages the position dynamic information sent from the mobile stations 11 to 14 in real time by the AVM system 202, performs automatic warning, and selects candidate vehicles. Therefore, it is possible to eliminate human error and notification delay.

  In addition, if the staying duration is long, you cannot receive a wireless dispatch, so the vehicle will travel voluntarily to earn the revenue of the wireless dispatch, resulting in the acquisition of free customers and taxis Increase in company sales can be expected.

  In the above embodiment, a case has been described where a mobile station with a short stay duration is preferentially targeted for dispatch. It is also good.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the second embodiment, for example, a vehicle dispatch processing system in the case where a break time of a taxi crew member determined in advance in a corporate taxi company or the like is managed on the management center side is shown.

  The overall configuration of the dispatch processing system according to the second embodiment is the same as that shown in FIG. 1 of the first embodiment. As shown in FIG. 6, each mobile station 11 to 14 has a digital radio 42, a GPS receiver 44, a charge meter on the operation display 41 based on the AVM system, as shown in FIG. 2 of the first embodiment. The operation unit 412 of the operation display 41 includes a break button 31 and a break release button 32 in addition to “response”, “accept”, and the like as function keys. The break button 31 is pressed when taking a predetermined break time, and the break release button 32 is pressed when ending the break. The operation information of the break button 31 and the break release button 32 is transmitted to the management center 20 as dynamic information.

  FIG. 7 shows a conceptual diagram when the management center 20 manages the breaks of the mobile stations 11 to 14.

  In FIG. 7, reference numerals 11, 12, and 13 denote mobile stations that are currently running, and reference numeral 14 denotes a mobile station that is taking a break. Each of the mobile stations 11 to 14 always transmits the current position information and dynamic information A to the management center 20 with a periodic polling signal from the base station 21 as a base point. The management center 20 includes a vehicle management information database 201, communicates with each mobile station 11 to 14 via the base station 21 by the AVM system 202, and collects position dynamic information A of each mobile station 11 to 14. It stores in the vehicle management information database 201, and manages the mobile stations 11-14.

  Next, the processing operation when the management center 20 manages the breaks of the mobile stations 11 to 14 will be described with reference to FIGS. 6 and 7 and the flowchart shown in FIG.

  When a crew member of each mobile station 11-14 wants to take a break, as shown in FIG. 6, he presses the break button 31 provided on the operation unit 412 of the operation indicator 41 to make the break after the mobile station dynamics are taken as a break. enter. In this example, a case where a crew member of the mobile station 14 enters a break by pressing the break button 31 will be described. When the break button 31 is pressed, the mobile station 14 transmits the dynamic information indicating the break along with the position information from the digital wireless device 42 to the management center 20 side.

  When the management center 20 receives the position dynamic information from each of the mobile stations 11 to 14 (step B1), if the break information is sent as the dynamic information, the management center 20 refers to the vehicle management information database 201 and takes a break. It is determined whether or not to start (step B2), and if it is a break start, it is registered in the vehicle management information database 201 (step B3). In this example, since the break information is sent from the mobile station 14, the fact that the mobile station 14 has entered a break is registered in the vehicle management information database 201. Next, referring to the vehicle management information database 201, the cumulative time of the rest time of the mobile station 14 on that day is calculated (step B4), and it is determined whether or not a predetermined preset rest time has been exceeded (step B4). B5). If the total break time does not exceed the set break time, the process returns to step B1 to receive position dynamic information from each mobile station 11-14.

  When break information is received as dynamic information from the mobile station 14 by subsequent polling, it is determined whether or not a break is started in step B2. In this case, since the break is not started, the process proceeds to step B10 and the mobile station 14 is started. A determination is made whether is taking a break.

  If it is determined that the user is taking a break, the process proceeds to step B4 to calculate the total rest time of the mobile station 14 on that day, and determines whether the total rest time exceeds the set break time (step B5). ).

  When the total break time of the mobile station 14 does not exceed the set break time, as described above, the process returns to step B1 to receive the position dynamic information from each of the mobile stations 11-14.

  The crew member of the mobile station 14 presses the break release button 32 provided on the operation unit 412 of the operation display 41 when finishing the break after taking a predetermined break. When the break release button 32 is operated, break release information is sent from the mobile station 14 to the management center 20 as dynamic information.

  When receiving the break release information from the mobile station 14 at Step B1, the management center 20 proceeds to Step B11 through Steps B2 and B10 to determine whether or not the break is released. The dynamic information indicating that “the mobile station 14 is taking a break” is released (step B12), and the process returns to step B1. Further, when other dynamic information is sent from each of the mobile stations 11 to 14, it is determined in the determination process of Steps B2, B10, and B11 that it is neither a break start, a break, or a break release, In B13, processing according to the dynamic information is performed, and then the process returns to Step B1.

  If the mobile station 14 does not operate the break release button 32 within a predetermined break time, it is determined in step B5 that the total break time of the mobile station 14 exceeds the set break time, Proceed to step B6. In this step B6, it is determined whether or not a break time exceeded warning message (or alarm) has already been transmitted. If it has not been transmitted yet, a break time exceeded warning message B is transmitted as shown in FIG. 14 (step B7).

  The mobile station 14 that has received the warning presses the break release button 32 to end the break. However, if the mobile station 14 receives a warning that the break time has been exceeded but ignores the warning and continues the break, the management center 20 proceeds from step B6 to step B8 to determine whether the break excess time is a predetermined setting. It is determined whether or not the time has been exceeded. If the time exceeding the break or the predetermined set time is not exceeded, the process returns to step B1. However, if it is determined in step B8 that the break excess time or the predetermined set time has been exceeded, the management center 20 transmits a forced break release command D to the mobile station 14 as shown in FIG. 7 (step B9).

  When the mobile station 14 receives the break release command D from the management center 20, the mobile station 14 forcibly releases the break state by the information processing unit 413 of the operation indicator 41 so that the rest cannot be set thereafter. At this time, the information processing unit 413 informs the crew member that the break state has been forcibly released by displaying a warning message on the display unit 411 as necessary or generating an alarm sound.

  As described above, the break time of the mobile stations 11 to 14 is managed on the management center 20 side, a warning is given to a mobile station that has been taking a break over a certain period of time, and the mobile station that continues the break by ignoring the warning Therefore, it is possible to correctly perform labor management of the crew by forcibly canceling the break state so that the rest cannot be set thereafter.

  In the above embodiment, a case has been described in which each mobile station is provided with a GPS receiving unit 44 to receive radio waves from the GPS satellite 26 and acquire current position information. A car navigation device including a unit may be installed, and current position information acquired by the car navigation device may be used.

  Further, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
