[0003]

2. Description of the Related Art At present, a management system by radio is mainly operated in the taxi industry. This system completes dispatch to a mobile station (taxi) responding to a dispatch notification broadcast from the center station. However, in this system, the location of the mobile station cannot be ascertained by the center station, and the dispatch cannot be completed without a response from the mobile station, so that the dispatch efficiency cannot be reduced.

[0004]

In view of the above, a system for transmitting a position information to a mobile station has been provided, and a system capable of grasping the position of a vehicle at a center station has been operated. However, this system is still insufficient for accurately grasping the vehicle position because the crew has to input the position information.

In addition, when considering the current system from the user's side, there is a problem that the queue is likely to be long due to the limited number of taxi stands. In particular, in bad weather (rain, snow, etc.), in this case, the user has to wait a long time outdoors, which is not a convenient system for the user.

The present invention has been made in view of the above points, and realizes a moving object management system that can effectively utilize limited vehicles and personnel and that is convenient for users. It is intended to propose a management station device and a mobile station terminal device that can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

(1) Taxi AVM (Automatic Vehicl)
e Monitoring) System FIG. 1 shows a schematic configuration of the system. The taxi AVM system 1 is composed of a center station 2 and a base station 3, and a mobile station 4 and a calling station (a vending machine 6 and a POS terminal 7A of a store 7 in the figure) which form a network through these. Have been. In this system, the position of the mobile station 4 is
The method is obtained by a GPS radio wave received from the S satellite 5. As a result, accurate and high-resolution position information can be obtained irrespective of manual input by the crew. In this system, an error of 5 m or less is realized by receiving GPS radio waves from eight GPS satellites 5.

The center station 2 receives the position information thus positioned via the base station 3 so that each mobile station 4
The exact location has been centralized. The center station 2 collects not only the location information of the mobile station 4 but also various other information by using both an arbitrary call and polling.

The center station 2 has a vending machine 6 and P
A dispatch request is received from the OS terminal 7A via a wireless network or a telephone network, and a dispatch instruction is issued to the mobile station 4 running near the installation position of each of these calling stations. The vending machine 6 and the POS terminal 7A used in this system
There is a push button for calling a taxi, a communication unit,
A display, a ticketing printer, and the like are provided. Details will be described in the following sections.

(2) Center Station (2-1) System Configuration As shown in FIG. 2, the center station 2 is provided with a plurality of dispatching terminals 2A for managing the mobile station 4 via the base station 3. I have. The plurality of dispatching terminals 2A are connected to each other via a local area network 2B. A communication server 2C and a database server 2D are connected to the local area network 2B, so that databases such as customer information and vehicle information (including position information) can be shared between the terminals.

As a result, the database 2D1 does not have to be provided for each dispatching terminal 2A, and the installation space can be reduced. In addition, the operator can access a plurality of base stations 3 with one dispatching terminal, and can issue dispatch instructions to the mobile station 4 moving in the area managed by each base station 3.
Thus, even when dispatch instructions are concentrated on the mobile station 4 in the area in which the specific base station 3 is in charge according to the day of the week or time zone, dispatch instructions can be shared by a large number of operators.

(2-1-1) Database Next, the structure of the database 2D1 will be described. The database 2D1 divides the map into small areas by a grid having one side separated by a predetermined distance (for example, 100 [m]), and manages the mobile station 4 in units of small areas. That is, database 2D
Numeral 1 manages the body number, the number, the operation status, and the like (FIGS. 3 and 4) of the mobile station 4 moving in the area for each small area.
Incidentally, this small area is set irrespective of the business area or administrative unit. By limiting the management area to a relatively small area in this way, an empty car moving near a point designated by a customer can be easily specified, and dispatch can be performed promptly.

The data contents of the database 2D1 are sequentially updated with position data and operation data transmitted from the mobile station 4. The update timing of the position data is basically when the mobile station 4 crosses the boundary of the small area. At this time, since the position data is transmitted from the mobile station 4, the center station 2 updates the data content of the database 2D1 using this.

However, when the road is located near the boundary of the small area, the mobile station 4 frequently enters and exits the two areas. Therefore, the hysteresis is provided so that the data can be updated only when the mobile station 4 has entered a predetermined distance or more from the boundary. It is made to provide. However, with these alone, the data cannot be updated for the mobile station 4 that has been stopped for a long time, so that the position data can be taken in at regular intervals by an instruction from the center station 2 (base station 3).

On the other hand, the data content of the database 2D1 is also changed when there is a change in the operating state, such as when waiting at a specific waiting place (a taxi stand) or the like. However, in the standby at the specific standby location, a change to the standby state is accepted only when the position of the mobile station 4 is within a predetermined range (for example, 100 [m]) from the specific standby location. This allows the management data to be in line with the actual situation.

The database 2D1 also manages the correspondence between the base station 3 used for data transmission to the mobile station 4 and the small area where the mobile station 4 is located. This makes it possible to realize a function of transmitting vehicle allocation information only to the optimal base station 3 when transmitting vehicle allocation information or the like to a specific mobile station 4 located in a certain small area. . Further, the database 2D1 also stores, as management data, the correspondence between the place names on the map and the landmarks and the small areas. As a result, a small area can be specified simply by inputting a place name or a target specified by a customer by an operator. This means that the mobile station 4 that meets the customer's condition can be searched immediately.

Incidentally, a learning function is added to this function. This learning function corresponds to a house map or the like, and enables to realize the most efficient arrangement corresponding to the actual terrain (road or river). For example, even if the mobile station 4 is located in the area corresponding to the point specified by the customer, if it is difficult to access the specified point due to conditions such as one-way traffic, the surrounding area is allocated to the moving mobile station 4. It is reasonable to issue a command. The database 2D1 stores such dispatching examples so that dispatching efficiency can be improved.

The center station 2 is provided with an automatic dispatch function using this function. That is, matching is performed between the area to which the point designated by the customer belongs and the position of the mobile station, and a dispatch instruction is transmitted to the mobile station 4 that has achieved the matching. At this time, if the dispatch is not completed within a predetermined time, the matching range is extended. That is, the small area adjacent to the first area is extended to the matching range.

(2-1-2) Display Screen Next, a display example displayed on each display of the dispatching terminal 2A is shown in FIGS. The feature of this display method is the adoption of a window display function. In the past, the display was divided into multiple displays, so a large space per terminal was necessary, and it was necessary to move the line of sight every time the information was confirmed. It has also been made easier.

In the case of this example, a mesh display screen W1, a reservation / acceptance screen W2, an empty vehicle screen W3, a vehicle allocation record screen W4, an all-vehicle display screen, a display of a vehicle traveling direction, etc. can be confirmed on one screen on the same screen. Has been made. Among them, the mesh display screen W1 is a screen for displaying management data relating to small areas obtained by dividing a map into a matrix. The maximum area division number of the small area displayed on this screen can be arbitrarily set within the business area. This screen can also display a grid superimposed on the map, allowing the user to check the terrain that cannot be grasped only by character display. By the way, a terrain enlarged display function is also provided.

The display contents of each small area constituting the mesh display screen W1 include the area name "Shinagawa Kita" and the "vehicle number" of the empty mobile station 4 that first entered the area.
In addition, the “number of vehicles” that are moving in the area while the vehicle is empty are prepared. The area displayed on the mesh display screen W1 can be switched by operating the mesh page switching button.

Detailed information of the mobile station 4 regarding each of these areas includes an empty vehicle information screen W3, a vehicle allocation record window W4,
It is displayed on the dispatch reservation screen W5 and the specific waiting place display screen W6. Incidentally, these display screens are switched in response to selection of a small area by a mouse click operation or the like. First, on the empty vehicle information screen W3, in addition to the vehicle number, the operating status, the traveling direction, and the number of allocated vehicles are displayed.

The vehicle allocation record window W4 displays the progress of vehicle allocation. Furthermore, in addition to the name of the customer who has not completed dispatch, the district name and the reception time are displayed on the dispatch reservation screen W5, so that the operator can confirm the customer who has been waiting for a long time. For a customer who has not been assigned for a certain period of time, the display color is inverted or a window is opened to call attention.

On the specific waiting place display screen W6, a specific waiting place (a taxi stand or the like) in the small area, the number of the vehicle arranged at the head and the number of waiting vehicles are displayed. Incidentally, the waiting place can be freely set. In addition, a history list W7 of the whole reception, dispatch information, and the like is displayed on the display screen of the display. A plurality of special keys K1, K2,.
Is provided. Here, the emergency call key K1 blinks at the time of an emergency call from the mobile body, and a function to be connected to the radio by clicking is assigned.

The fixed sentence sending key K2 is a key for transmitting a message to a specific moving body. The voice key K3 is a key for realizing a voice call to a mobile object. In addition, registration of customer information in the system key K4,
In addition to deletion, it is used for administrator settings such as administrator registration, master deletion, copying, and password setting. Also provided are vehicle management, suspension, vehicle registration, printing, and daily / monthly printing functions. The map switching key K5 is a key for switching between mesh and map.

Finally, the reservation / acceptance screen W2 will be described. FIG. 5 shows an example of the reception screen, and FIG. 6 shows an example of the reservation screen. In this field, if the customer name is registered at the time when the customer name is input, the boarding location and the guidance text are automatically displayed on the screen. If the contents are correct, the display of the corresponding small area is changed. On the other hand, when the customer name is not registered, when a search is instructed for a town name, a destination, or the like input by the operator, the display method of the corresponding small area is changed.
That is, the color density and luminance are changed.

(2-2) Operation Procedure Next, the operation at the time of dispatch by the operator will be described. Here, FIG. 7 shows a schematic flow. Figure 8 shows the detailed flow
It is as follows. First, upon receiving a telephone call from the customer, the operator checks whether the vehicle is reserved or dispatched immediately (step SP1, step SP2). In the case of vehicle allocation, the process proceeds to a search process for a customer (step SP3). At this time, the search is performed using the last six digits of the telephone number. However, a name or address may be used. Here, when the customer information has been registered, the operator selects from the corresponding list. On the other hand, if not registered, it is confirmed by telephone and registered in customer data.

Next, move on to the designation of the district (step SP
4). In the case of a new customer, an area is selected by moving a cursor to a small area corresponding to the corresponding area and clicking an operation key of a mouse. The selected district is automatically registered in the customer database, and the next time the customer is called, the district can be automatically designated. If there are no vacancies in the area,
Select from among the eight vacant, vertical, horizontal, and diagonal areas in the area where there are many empty vehicles. In this case, it is confirmed whether the customer can be reached within 10 minutes. If there is no corresponding car in these 8 areas, the dispatch is suspended. In addition, the specific waiting place is subject to the area including the waiting place.

When the designation of the district is completed, the process proceeds to the calling of the corresponding car (step SP5). At this time, the corresponding vehicles in the designated area are displayed in the order of the oldest updated data (the order in which they first entered the area), and the mobile station 4 with the oldest data is automatically called. Incidentally, the mobile station 4 at the specific waiting place is also a target of the corresponding vehicle.

When the corresponding car is determined, the procedure proceeds to transmission of a guidance sentence (step SP6). At this time, the guidance sentence is transmitted as voice or data. That is, if you are a new customer,
If the registered customer is the same as the guidance text, character data is transmitted. Incidentally, a voice mail function is provided for transmitting the guidance text. This function is used to select a relevant area when a customer requests a dispatch, but if there is no vacancy in that area, record the guidance text (voice) and automatically enter it when the vacant vehicle enters the customer's dispatch area. To send a guidance text to the empty vehicle.

After this, the operation moves to step SP7. Here, when the mobile station 4 returns an acknowledgment (timeout is 5 seconds × 2), the customer is notified. On the other hand, if there is no response, the process moves to the next candidate mobile station 4. At this time, the vehicle allocation record (vehicle allocation number, time, customer name, telephone number) is automatically registered. Then, when a response from the mobile station 4 is obtained, the process proceeds to step SP8, where the vehicle number and the estimated arrival time are notified to the customer to complete a series of vehicle allocation procedures.

(3) Mobile Station (3-1) System Configuration Next, the system configuration of the mobile station 4 will be described with reference to FIG. In this system, the position of the vehicle is measured by receiving a GPS radio wave by a GPS antenna 4A integrated with a receiver.
The measured position information is processed by the display-type operation device 4B and sent to the modem / converter 4D which plays a central role in this system. The display type operation device 4B is provided with a card slot.
Information unique to the vehicle can be easily updated simply by attaching and detaching the C card 4C to and from the card slot.

In the IC card 4C, in addition to the vehicle-specific information, the guidance sentence received from the center station 2 is displayed on the screen if the moving speed of the mobile station 4 is lower than a certain speed and there is no response instruction from the crew. A program for controlling the display-type operation device 4B so as not to be displayed is written.

A speaker 4E and a radio 4F are connected to the modem / converter 4D in addition to the display-type operation device 4B. As a result, audio captured through the antenna 4G can be reproduced through the speaker 4E, and various instructions can be captured in the display-type operation device 4B and displayed on the display 4B1. Incidentally, the voice fetched from the microphone 4I is transmitted from the antenna 4G via the radio 4F.

In addition, a toll meter 4H is connected to the modem / converter 4D. As a result, the modem / converter 4D can capture the operating state (FIG. 3) of the mobile station (taxi) 4 and simultaneously transmit the position information obtained from the GPS antenna 4A to the base station 3 from the antenna 4G. It has been done.

(3-2) Configuration of Modem / Converter 4D Next, FIG. 10 shows the internal configuration of the modem / converter 4D. The modem / converter 4D is configured around a CPU 4D1. Here, a display type operation device 4B, a speaker 4E, a radio 4F, and a charge meter 4 externally connected to the modem / converter 4D.
H is directly or indirectly connected to the CPU 4D1.
The modem / converter 4D controls transmission and reception of data to and from the base station 3 around the CPU 4D1.

Now, as a configuration specific to the modem / converter 4D, there are a memory 4D31 provided in the demodulator 4D3 and a recording IC 4D32. With the recording IC 4D32, the dispatch instruction given by voice from the base station 3 (center station 2) can be digitally recorded in the memory 4D31, so that the crew of the mobile station 4 can check the contents of the dispatch instruction any number of times. Has been made. With this, it is expected that more reliable vehicle allocation can be realized.

The modem / converter 4D has an audio digital control function. As a result, only the specific vehicle specified by the center station 2 is
It is made possible to hear the voice from.
This function can also enhance the confidentiality of the customer information at the time of dispatch instruction. In addition, the call between the mobile station 4 and the center station 2 can be switched between a call with an adopting group (by business office), a broadcast (all vehicles), and the like, in addition to such a one-to-one call. . Incidentally, the switching can be arbitrarily performed on the center station 2 side.

(3-3) Configuration of the display-type operation device 4B Finally, the information display function and operation buttons of the display-type operation device 4B will be described with reference to FIG. First, the functions assigned to the operation buttons 4B2 to 4B18 will be described in order. Call button 4B2 is mobile station (taxi) 4
This button is provided to notify the center station 2 with the highest priority when an emergency such as an accident occurs. When this button is operated, transmission is continued regardless of the communication state of another taxi. Incidentally, this function can be canceled only from the center station 2. At this time, the security light is not blinking. In order to further prevent erroneous operation, a confirmation operation is inserted in the operation of this button.

Next, the area button 4B3 is a button provided for sequentially switching the business areas. By operating this button, the specific standby place displayed on the screen is switched. The charter button 4B4 is a button to be pressed when operating as a charter car. For canceling, the cancel button 4B17 may be pressed. The forwarding button 4B5 is a button pressed when taking a break. In the case of canceling, the cancel button 4B17 may be pressed.

The empty reservation button 4B is a button to be pressed when an empty vehicle is scheduled. Cancel button 4B17 to cancel

The receive button 4B8 is pressed to display the two latest received messages simultaneously. However, even if this button 4B8 is pressed during traveling, the received message is not displayed. FIG. 13 shows an example of the received message displayed at this time. Incidentally, when the "forgotten item inquiry" of "9" is received, "forget" is displayed on the screen. Here, when the OK button 4B11 is pressed, the contents shown in FIG. 14 are displayed for the first time.

Similarly, when "13""traffic under control" is received, "interchange" is displayed on the screen. Here, when the OK button 4B11 is pressed, the contents are displayed. In addition, when "under construction" of "14" is received, "OK" is displayed on the screen. Here, when the OK button 4B11 is pressed, the contents are displayed. In addition, when an emergency message is received from the center station 2, an emergency contact screen as shown in FIG. 15 is displayed. In order to delete these displays, the user only needs to press the cancel button 4B17. If this button 4B17 is pressed, the display automatically disappears after a certain period of time.

The guidance text button 4B9 is a button to be pressed when displaying the latest guidance text. However, even if the button is pressed during traveling, the contents of the guidance text are not displayed. If the user wants to delete the image, he presses the cancel button 4B17. Also charge meter 4H
Guidance sentence disappears even if you press the wage, surcharge and payment. In addition, it disappears when a new guidance sentence is received. The OK button 4B11 is a button to be pressed when responding to a dispatch request or a dispatch cancellation request.

The standby button 4B10 notifies the center station 2 of a specific standby place selected by the current position or direction button (“←”, “→”, “↑”, “↓”) 4B18. The cancel button 4B17 is pressed to cancel a specific standby place, forwarding, vacant schedule, or charter. Also, this button is pressed to delete the displayed message. The play button 4B12 is a button to be pressed when playing the latest recorded message.

(3-4) Display Screen Next, the display screen displayed on the display 4B1 of the display-type operation device 4B will be described.

(3-4-1) Display of Specific Standby Location In this example, the description will be made assuming that the maximum number of specific standby locations is 36 for each business area. Display 4B1
Displays, at a time, 12 specific standby locations of 3 columns × 4 rows on the screen out of 36 specific standby locations allocated on the 6 columns × 6 rows. FIG. 16 shows a display example. Incidentally, the name of the specific standby place is represented by a maximum of four characters. In addition, the number of vacant vehicles in each standby place is displayed below the square. By checking this number, the crew can also move to a relatively vacant specific waiting place.

Now, regarding the display screen of the display 4B1, the brightness (color) of the specific standby place closest to the latest position among the twelve specific standby places is reversely displayed. This allows the crew to easily identify the nearest specific waiting place. Further, when the specific standby place closest to the latest position deviates from the display area, the display area is automatically switched. No scrolling. Incidentally, in order to switch the display area, a manual switching mode is prepared in addition to the automatic switching mode. In this case, the area button 4B3 may be pressed as described in the previous section. At this time, the display area can be switched clockwise as shown in FIG.

(3-4-2) Specific Standby Location Setting Next, the setting of the specific standby location will be described. Normally, the closest specific waiting place is highlighted. If the setting key is pressed here, the specific standby place is registered in the center station 2. GP
If you want to set an arbitrary specific standby place, for example, when you are in a place where S radio waves cannot be received, select and set the direction button (“←”, “→”, “↑”, “↓”) 4B18. be able to.

The squares (markers) highlighted here
Is located at the end of the currently displayed area, and when the direction button 4B18 is further pressed, the display area automatically switches to the next area. However, it does not scroll. However, if the setting key is not depressed even if the marker is moved, it automatically returns to the nearest specific standby place after one minute.

However, this setting indicates that the distance between the latest position and the nearest specific standby location is 5 when GPS radio waves are being received.
The setting cannot be made unless it is within the range not exceeding 00 m. If the cancel button 4B17 is pressed while the specific standby place is displayed, the display can be canceled.

(3-4-3) Display of dispatch instruction and display of guidance message When the mobile station 4 receives the dispatch instruction from the center station 2, the mobile station 4 sounds an alarm sound to inform the crew of the reception of the dispatch instruction and displays the dispatch message. It has been made to display on the top. OK button 4B when stopped
When "11" is pressed, a guidance text is displayed, and the dispatch is completed.
On the other hand, when the vehicle is running, even if the OK button 4B11 is pressed, the guidance text is not displayed in order to secure the safety in running. In this case, an alarm sound indicating that the vehicle is running is sounded. However, the dispatch is completed at this point. When the vehicle stops, a guidance text is displayed at that time. When the vehicle is running again, the guidance text is erased. By the way, the guidance sentence disappears when "wage running", "surcharge", "payment" or "cancel" is pressed.

The determination as to whether or not the vehicle is running is made based on whether or not the GPS speed is 10 km / h or more. That is, when the speed is 10 km / h or more, the vehicle is traveling, and when the speed is less than 10 km / h, the vehicle is stopped. However, when it is impossible to receive the GPS radio wave and it is impossible to determine whether or not the vehicle is running, it is assumed that the vehicle is stopped and the display is performed. The above is the operation in the case of accepting the dispatch message, but the OK button 4B is displayed even if the dispatch message is displayed.
If 11 is not pressed, dispatch is canceled in 10 seconds,
"The dispatch has been canceled." Is displayed on the display.

This display, that is, "allocation is canceled" disappears in 5 seconds. In addition, when the cancel button or the OK button is pressed, it is also erased. Note that the maximum length of the customer name displayed as shown in FIG. 18 is 26 double-byte characters (13 characters × 2 lines), and the maximum length of the guidance sentence is 65 double-byte characters (13 characters × 5 lines). In addition, a guidance text including a landmark (Murayama Station, Hinodecho intersection, Seven-Eleven), a direction (right turn), or a distance (200 m) as shown in FIG. 18 is displayed, and the crew follows the guidance text. If you drive, you can easily reach the customer's boarding place. FIG. 19 shows the state transition.

(3-4-4) Display of present date and time and display of operating state of mobile station The contents to be displayed are “month”, “day”, “day of the week”, “hour”,
"Minute". The time is automatically set by receiving GPS radio waves. By using the GPS radio waves, it is possible to synchronize the internal clocks of all the mobile stations 4. The operating state of the mobile station 4 is always displayed. The content is "standby", "forwarding", "empty reservation" or "chartered", and the display is "wait", "times",
“Pre” and “Rent”.

(4) Calling station (4-1) Configuration of vending machine with dispatch request function Next, a number of vending machines are installed throughout the town as calling stations for realizing shortage of taxi stands and reduction of waiting time. FIG. 20 shows a system configuration using. When a taxi dispatch request button (here, a taxi button 6B) is pressed in a state where coins 6A (for example, 100 yen) or bills are inserted, the vending machine 6 constituting this system makes a telephone line or wireless connection to the center station 2. And a vehicle allocation request signal is output. The detailed configuration of the vending machine 6 will be described.

The vending machine 6 recognizes the insertion of the coin 6A by the coin discriminator 6C, and when the coin 6A is inserted, gives the coin insertion signal S1 to the processing device 6D and waits for an input from the operation button. Has been made. Incidentally, the coin discriminator 6C is configured to refund the inserted coin 6A and bills to the user when the return lever 6E1 is operated. The processing unit 6D is connected to the taxi button 6B in addition to the normal product selection button. When the taxi button 6B is pressed, the center station 2 is connected via the modem 6E and a network control unit (NCU: Network Control Unit) 6F. Is transmitted to the vehicle.

At this time, a serial number or the like assigned in advance to the vending machine 6 is transmitted as the dispatch request signal S2. Incidentally, position information (including a place name and an address) paired with the serial number is stored in the center station 2 side. Therefore, when the dispatch request signal S2 is received, the center station 2 identifies the point on the map of the vending machine 6 to which the dispatch request has been issued, and based on this point, the vending machine 6 to which the dispatch request has been issued. Can be automatically searched for on the database 2D1.

The vending machine 6 to which the dispatch request has been transmitted.
If an empty vehicle traveling closest to is identified,
A dispatch instruction is sent from the center station 2 to the mobile station 4. When a response to the dispatch instruction is obtained from the mobile station 4, the center station 2 sends a dispatch completion signal S3 to the vending machine 6, and receives the signal by the processing device 6D of the vending machine 6. . At this time, the processing device 6D outputs the vehicle allocation completion signal S3
The taxi company name, vehicle number, waiting time (estimated) and the like given by the taxi are displayed on the display 6G to inform the user of the dispatch situation.

In addition, the processing unit 6D gives the company name and the vehicle number of the taxi for which the dispatch has been completed to the paper feeder 6H, and the information is sent to the ticket 6 by the printer 6I.
It is printed on J and output. By issuing such a ticket 6J, even if there are a plurality of users who have issued a dispatch instruction through the same vending machine 6, the dispatcher can reliably use the dispatcher.

(4-1-1) Processing Procedure Next, a taxi dispatch procedure using the vending machine 6 and a processing procedure at that time will be described with reference to FIG. Usually, if you want to buy tobacco or drinking water sold by the vending machine 6,
The user presses a product selection button after inserting a predetermined amount of money. However, when issuing a dispatch instruction to a taxi, a predetermined amount of money (in this case, 100 yen), then step SP
Press the taxi button 6B as shown at 53. Then, the processing device 6D detects this, and outputs a dispatch request to the center station 2 (step SP54).

The center station 2 having received the dispatch request automatically specifies the position of the vending machine 6 to which the dispatch request signal S2 has been output from the dispatch request signal S2. Subsequently, the center station 2 reads information such as the company name, the body number, and the operating status of the taxi (that is, the mobile station 4) that moves in the small area where the vending machine 6 that has issued the dispatch request is installed, for a predetermined time. Then, the process proceeds to an automatic detection operation of whether or not there is an empty vehicle that can arrive within (in this example, 10 minutes) (step SP55).

If a positive result is obtained (ie, if there is an empty vehicle that can arrive within 10 minutes), the center station 2 issues a dispatch instruction to the corresponding vehicle, and
Information such as the company name, vehicle number, and expected waiting time of the taxi dispatched to the vending machine 6 is transmitted as a dispatch completion signal S3. This information is displayed on the display 6G as shown in step SP56, and is notified to the user. Thereafter, the process proceeds to step SP57, and a ticket 6J on which the company name and the vehicle number of the taxi for which dispatch has been completed is printed is issued from the printer 6I (step SP57 to step SP59).

On the other hand, if a negative result is obtained in step SP55 (that is, if there is no vacant vehicle that can be reached within 10 minutes), the processing of the center station 2 shifts to step SP60, and the automatic dispatch request is issued. The search range is expanded to a plurality of areas including the vicinity of the small area where the vending machine 6 is installed, and although it takes a little time to arrive, a taxi running closest is searched. Then, the distance is measured on the basis of the obtained positional relationship, and the estimated dispatch time required for the corresponding taxi to reach the vending machine 6 is obtained and sent to the vending machine 6.

The vending machine 6 displays the information received from the center station 2 such as the company name, the vehicle number, and the estimated waiting time on the screen of the display 6G, and displays a predetermined message ("about XX minutes"). Press the taxi button 6B again. If cancel, press the return lever 6E1. ") (Step SP61 and Step SP62). In this way, the user has the final right to determine the dispatch instruction when the waiting time is long.

In this state, if a positive result is obtained in step SP63 (that is, if the taxi button 6B is pressed), the process proceeds to step SP57, where the company name and vehicle number of the taxi for which the dispatch is determined are printed on the ticket 6J and the ticket is issued. Is done. Incidentally, a predetermined amount of money is printed on the ticket 6J issued at this time in addition to the above-mentioned vehicle information, so that the ticket 6J can be used as a cash voucher when the user gets on a taxi. In this way, no refund will be given when the dispatch is completed, and it will be possible to use it as part of the fare that can be used when boarding.

On the other hand, if a negative result is obtained in step SP63 (that is, if the taxi button 6B is not pressed), the process proceeds to step SP64 to return the coin return lever 6E.
Becomes ready to be operated, and the return lever 6
The money inserted earlier at the stage when E is pressed is refunded (step SP64 to step SP66).

The user can easily instruct taxi dispatch by these series of operations. In addition, since a large number of vending machines 6 are installed not only in a city area but also in a residential area or on a main road, a taxi can be reliably used even in a suburb where there are few taxi stands. This saves you from having to search for a vacant taxi on the street that you may never know. Also, as described above, the center station 2 constituting this system has a database of vehicle information updated in real time, and instructions such as taxi instructions are registered and recorded in advance. This allows automatic dispatching without passing through an operator in the center station, so not only does the burden on the system operator increase, but also a further reduction in the vacancy rate can be expected.

(4-2) POS (Poin) with dispatch request function
t Of Sales) Terminal Configuration In the previous section, the case where a function of outputting a dispatch request to the center station 2 that manages a taxi was added to the vending machine 6 was described, but in this section, a convenience store, a store, etc. A system in which a taxi is dispatched to an installed POS register will be described. Today, convenience stores are widely scattered in commercial and residential areas. In addition, since business hours are often long, it is considered to be a convenient place for users even when calling a taxi late at night or when the weather is bad. Also, considering that there is a chance to have the customer purchase the product during the waiting time, the system is convenient for the store 7 having the POS register 7A. An example of a system configuration for realizing these is shown below.

(4-2-1) Configuration Example 1 First, parts corresponding to those in FIG.
Shows a first configuration example. FIG. 2 shows the POS register 7A.
In addition to the circuit block shown in FIG. 2, a circuit block and the like used for a cash accounting function and the like, which are original functions, are built in, but are omitted here. As can be seen from the figure, the internal structure is almost the same as the circuit block mounted on the vending machine 6, and the dispatch to a taxi can be realized by the same processing procedure. Further, in this example, since the POS register 7A of the store 7 and the center station 2 are connected via a telephone line, the configuration is such that the subscriber telephone 7B is connected via the network control device 6F.

(4-2-2) Structural Example 2 In the preceding section, a case was described in which the POS register 7A has a built-in function block for dispatching. However, as shown in FIG. It can also be applied to Here, the device shown in FIG. Incidentally, the POS register 7A and the in-store dispatch terminal 8 are connected through a serial line. For this reason, the in-store dispatch terminal 8 is a serial interface 8A.
It is configured to send and receive data through. With this configuration, retrofitting and the like can be performed, and convenience for the store can be improved.

(4-2-3) Configuration Example 3 Next, a third configuration example will be described with reference to FIG. This example uses a plurality of POS registers 7 via a store controller 7D.
2A is an example of a system configuration in which a modem / network control device 7C is shared by A. Of course, it is assumed that the POS register 7A contains various circuit blocks necessary for outputting a dispatch request to a taxi. However, in this case, the display unit provided for displaying the amount of money and the like in the POS register 7A from the beginning is also used as the display 6G, and the printing function prepared for printing the receipt is printed on the ticket 6J. Shall be shared. With this configuration, a system configuration with a simple circuit configuration and high line use efficiency can be realized.

(5) Communication Protocol (5-1) Outline of Protocol Lastly, a communication protocol used in operating this system will be described. In this system, there are three communication protocol layers as shown in FIG. That is, there are a physical layer (physical communication protocol), a link layer (protocol between units), and an application layer (protocol between applications). Originally OSI
Normally, the seven layers of (Open System Interconnection) are independently defined, but are simplified to three layers in consideration of communication capacity and processing load.

The applicable range of each unit and protocol is as follows. First, the physical layer "1" is TTL-level asynchronous, full-duplex communication. Further, transmission control by CTS / RTS is performed. In the physical layer “2”, wireless communication of FM narrow modulation and wired communication of baseband are performed in series. The wireless part is half-duplex, and the wired part is full-duplex. The physical layer “3” is asynchronous, full-duplex communication at the RS-232C level.

On the other hand, link layer “1” and link layer “2”
Has an error detection function to which a checksum is added and a retransmission function. The link layer “3” adds an error correction and retransmission function using BCH to HDLC.

(5-2) Link Protocol (5-2-1) AVM-Selector The features of this link protocol are to minimize the communication capacity, to take into account the radio error rate, and to reduce the number of bit errors by using only received packets. In the case of multi-bit errors, retransmission of packets, and determination of collision of a plurality of packets. Link Packet Format (H
DLC) is shown in FIG.

(5-3) Application Protocol (5-3-1) Calling Conditions from Mobile Station Lastly, the calling conditions from the mobile station will be summarized and described including the above items. The calling timing common to all the mobile stations 4 is when the mobile station 4 crosses a grid boundary (mesh). This includes when you leave the area. However, it is possible to limit to only empty vehicles by setting the calling conditions from the center station 2. In addition, it can be limited to only a specific mobile station 4.

The interval between meshes can be changed from the center station 2. If you frequently cross the mesh,
A call can be reduced by providing a hysteresis width.
At this time, the mobile station 4 transmits the sub-mesh number and the direction of entry to the mesh to the center station 2. However, when the transmission waits due to busyton, the position at the time when transmission becomes possible shall be transmitted.

In addition, the following ten cases can be considered. When the state of the moving object changes (standby, empty,
Real car). AC for command from center station 2
When returning K (transmission of a dispatch instruction, transmission of an acknowledge button for cancellation of dispatch, etc.). When the emergency message switch is pressed. When the emergency message button is pressed. Mobile station 4
Has not been called for a certain period of time (for example, one hour).

When a failure occurs in the function of the mobile station 4. When reporting the results of self-diagnosis. At the time of installation request (including when repair is completed). When sending fixed messages (lost items, missing customers, accidents, etc.). When transmitting the number of packet retransmissions. The format and contents of the application packet used for transmission from the mobile station 4 to the center station 2 are as shown in FIG.

(5-3-2) Contents of Transmission from Center Station The contents of transmission transmitted from the center station 2 to the mobile station 4 will also be summarized, including the above items. First, dispatch request and dispatch cancellation. Emergency message transmission, free message transmission, fixed message transmission (lost items, accidents, crackdown, etc.)
Etc. message. Setting of operating conditions and time setting. Self-diagnosis request and position transmission request. Cancel emergency calls. Installation completion notification. ACK for mobile station data (sending call suppression and release requests simultaneously). The number of empty vehicles at the specific standby location. It is a road vector or a destination position. The format and contents of the application packet used for transmission from the center station 2 to the mobile station 4 are as shown in FIG.

(5-3-3) Operation Conditions That Can Be Remotely Set from the Center Station First, the transmission conditions of the position (all vehicles, empty vehicle (empty), specific ID,
(Specific group ID, area, all cars prohibited) can be controlled remotely. The mesh interval (2 km, 1 km,...) Can also be changed. In addition, the regular transmission time and the effective range of the specific standby place can be freely set. Further, the hysteresis width of the mesh, the transmission time slot length, the number of slots, and the slot number assigned to each mobile unit can be set. Also, the codes of the individual ID and the group ID of the moving object can be set. In addition, the range of the message (business area) and the name and position of the specific standby place can be remotely set, and the contents of the fixed message can also be set. Thus, various conditions are devised so that they can be set as needed.

(6) Other Embodiments In the above-described embodiment, the taxi management system using the taxi as the mobile station 4 has been described. However, the present invention is not limited to this, and the transportation management system for the collection and delivery truck is used. It can also be applied to The invention is not limited to this, and may be used as a staffing management system. Further, the present invention can be applied to a demand bus system that changes a route according to a demand of a user.

Further, in the above embodiment, a serial number or the like is assigned to the vending machine 6 in advance and registered, and when the taxi button 6B is pressed, the registered serial number is transmitted to the center station 2. However, the present invention is not limited to this, and the vending machine 6
Is assigned to each vending machine because the installation location may be moved.
A PS receiver may be mounted, and the position information received by the GPS receiver may be transmitted to the center station 2. By doing so, it is possible to save the trouble of updating the registered contents every time the installation location of the vending machine 6 is changed, which is convenient in operating the system.

In the above-described embodiment, the system in which the operator of the center station 2 accepts the dispatch and issues an instruction to each mobile station 4 has been described. However, the present invention is not limited to this. An incoming call type telephone network control device and a device for recognizing a DTMF sound by pressing a push button of the telephone are provided, and a dispatch instruction can be automatically issued to the mobile station when a customer or the like inputs a dispatch instruction by telephone from outside. It can be applied to such a system.

Further, the present invention is not limited to the above-described embodiment, and the following communication system may be adopted as the communication system of the mobile management system. For example, when controlling the transmission timing of each mobile station 4 based on a synchronization signal transmitted from a base station (center station), based on a GPS synchronization signal received by a GPS receiver mounted on the mobile station 4. Alternatively, the synchronization timing may be interpolated.

In this way, the synchronization timings of all the mobile stations 4 can be made substantially coincident. Further, if this function is used, the following control becomes possible. That is, a plurality of mobile stations 4 may be divided into groups, and a period during which communication with the base station 3 is possible may be managed for each group. By doing so, the probability of simultaneous calling can be reduced.

If this function is used, other methods can be considered. That is, when a voice call is made directly and in real time using a communication means of the same radio frequency as the data communication, a specific tone or control code is transmitted from the center station 2 and the mobile station 4 which receives this is transmitted. Can be stopped so as not to disturb the voice call.

As a method of transmitting voice and data in a coexistent manner, input voice information is digitized and temporarily held, whereby communication control information such as ACK for the vehicle is transmitted in advance. After that, the sound may be reproduced and transmitted.
