BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile management system, which is suitable for use in, for example, a taxi operation management system.

[0003]

2. Description of the Related Art Currently, a wireless management system is mainly used in the taxi industry. This system completes vehicle allocation to the mobile station (taxi) that responds to the vehicle allocation notification broadcast from the center station. However, with this system, the location of the mobile station could not be ascertained by the center station, and the vehicle dispatch could not be completed unless there was a response from the mobile station.

[0004]

Therefore, the operation of a system in which the mobile station side is equipped with a position information transmission function and the center station side can grasp the position of the vehicle is attempted. However, in the case of this system, it was still insufficient to accurately grasp the vehicle position because the crew had to input the positional information.

The present invention has been made in consideration of the above points, and an object thereof is to propose a mobile body management system capable of effectively utilizing a limited number of vehicles and personnel.

[0006]

In order to solve such a problem, according to the present invention, a map is divided into a plurality of small areas by a grid having one side at a predetermined distance and the mobile station (4) side A moving body management system (1) is provided by a database means (2D1) that manages automatically transmitted position information for each small area and a database updating means (2D1) that sequentially updates the data of the database means (2D1). ) Build.

Further, in the present invention, the map is divided into a plurality of small areas by a grid having one side at a predetermined distance interval,
Database means (2D1) for managing the position information automatically transmitted from the mobile station (4) side for each small area;
The mobile body management device is configured by the database updating means (2D1) that sequentially updates the database means (2D1) and the display means that displays the management information corresponding to the plurality of small areas in a matrix on the screen.

Further, in the present invention, a mobile management system is constructed by connecting the mobile management system (2A) to a plurality of base stations (3) via a network in a one-to-many form.

Further, in the present invention, a GPS receiver (4A) for detecting the position of the mobile station and a display means (4B1).
And operating state detection for detecting operating states of operation means (4B2) to (4B18) for switching display contents displayed on the screen of the display means (4B1), a wireless device (4F), and a mobile station (4). The means (4H) and the control unit (4D1) constitute a mobile terminal device.

[0010]

The position information automatically transmitted from the mobile station (4) side is managed by a small area on the map divided by a grid with one side at a predetermined distance interval, and this data is further stored. By sequentially updating, it is possible to realize a mobile management system in which the latest position of the mobile station (4) can be easily managed.

The management information displayed in a matrix on the screen of the display means corresponds to a small area formed by dividing the map by a grid having one side at a predetermined distance interval. It is possible to make it easier for anyone to grasp the positional relationship of the mobile station on the plane, as compared with the case of managing the mobile station by using the above method.

Further, by connecting the mobile unit management device (2A) to a plurality of base stations (3) via a network in a one-to-many form, one unit can manage a wide area. An efficient management system can be realized as compared with the case of connecting in a one-to-one form.

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

[1] First Embodiment (1) Taxi AVM (Automatic Vehicle Monitorin)
g) System Figure 1 shows the schematic configuration of the system. The taxi AVM system 1 is composed of three stations, a center station 2, a base station 3 and a mobile station 4. In this system, the position of the mobile station 4 is set to G
The method of obtaining by the GPS radio wave received from the PS satellite 5 is adopted. As a result, accurate and high-resolution position information can be obtained without manual input by the crew. Further, in this system, an error within 5 [m] is realized by receiving GPS radio waves from eight GPS satellites 5.

The center station 2 receives the thus-positioned position information via the base station 3 so that each mobile station 4 can receive the position information.
It is designed to centrally manage the precise position of the.
Incidentally, the center station 2 collects various kinds of information in addition to the position information from the mobile station by using both the arbitrary call and the polling. Detailed functions of the center station 2 will be described in the next section.

(2) Center Station (2-1) System Configuration As shown in FIG. 2, the center station 2 is provided with a plurality of dispatch terminals 2A for managing the mobile station 4 via the base station 3. There is. The plurality of vehicle allocation 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 a database such as customer information and vehicle information (including position information) can be shared between the terminals.

As a result, the database 2D1 can be dispensed with for each dispatch terminal 2A, and the installation space can be reduced. Further, by this, the operator can access the plurality of base stations 3 with one vehicle allocation terminal and can issue a vehicle allocation instruction to the mobile station 4 moving in the area managed by each base station 3.
Thus, even when the vehicle dispatching commands concentrate on the mobile stations 4 in the area that the specific base station 3 is in charge of depending on the day of the week or the time of day, a large number of operators can share the vehicle dispatching instructions.

(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 with one side having a predetermined distance interval (for example, 100 [m]), and manages the mobile station 4 using this as a unit. Ie database 2D
Reference numeral 1 manages, for each small area, the vehicle body number, the number of mobile stations 4, the operating status, etc. (FIGS. 3 and 4) of the mobile station 4 moving within the area.
By the way, this small area is set independently of business areas and administrative units. By thus limiting the management area to a relatively small area, it is possible to easily specify an empty vehicle that is moving near a point designated by the customer.

The data contents of the database 2D1 are successively updated by the position data and operation data transmitted from the mobile station 4. Among them, the update timing of the position data is in principle 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 uses this to update the data content of the database 2D1.

However, when the road is near the boundary line of the small area, the mobile station 4 frequently moves in and out of the two areas, so that hysteresis can be set so that the data can be updated only when the mobile station 4 enters a predetermined distance or more from the boundary line. It is designed to be provided. However, since the data cannot be updated for the mobile station 4 that has been stopped for a long time only with these, the position data can be fetched at an instruction from the center station 2 (base station 3) at regular intervals.

On the other hand, the data content of the database 2D1 is also changed when the operating state is changed, such as when waiting at a specific waiting place (taxi stand). However, the waiting at the specific waiting place is adapted to accept the change to the waiting state only when the position of the mobile station 4 is within a predetermined range (for example, 100 [m]) from the specific waiting place. As a result, the management data is adapted to the actual situation.

In addition to these, 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 in which the mobile station 4 is located. As a result, when transmitting vehicle allocation information or the like to a specific mobile station 4 located in a certain small area, a function of transmitting vehicle allocation information only to the optimum base station 3 can be realized. Furthermore, the database 2D1 also stores, as management data, the place names on the map and the correspondence between the target object and the small areas. This allows the operator to specify a small area only by inputting a place name or a target object designated by the customer. This means that the mobile station 4 that meets the customer's requirements can be searched immediately.

By the way, a learning function is added to this function. This learning function corresponds to a residential map, etc., and enables the most efficient arrangement corresponding to the actual topography (roads and rivers). For example, even if the mobile station 4 is in the area corresponding to the point designated by the customer, if it is difficult to access the designated point due to conditions such as one-way traffic, the surrounding area is dispatched to the moving mobile station 4. It is reasonable to issue an order. Such a vehicle allocation example is stored in the database 2D1 so that the efficiency at the time of vehicle allocation can be improved.

Incidentally, the center station 2 is provided with an automatic vehicle dispatching function using this function. That is, the area to which the point designated by the customer belongs and the position of the mobile station are matched, and a dispatch instruction is transmitted to the mobile station 4 that has been matched. At this time, if the vehicle allocation is not completed within the predetermined time, the matching range is expanded. That is, the small area adjacent to the first area is expanded to the matching range.

(2-1-2) Display Screen Next, a display example displayed on each display of the vehicle dispatch terminal 2A is shown in FIGS. The feature of this display method is the adoption of the window display function. In the past, since the display was divided into multiple displays, it was necessary to have a large space per terminal, and it was necessary to move the line of sight each time information was confirmed. By adopting this method, information on the space can be grasped. About is also made easy.

In the case of this example, the mesh display screen W1, the reservation / reception screen W2, the empty car screen W3, the vehicle allocation record screen W4, the all vehicle display screen, the display of the vehicle traveling direction, etc. can be confirmed on one screen on the same screen. Has been done. Of these, the mesh display screen W1 is a screen for displaying management data regarding small areas obtained by dividing the map into a matrix. The maximum district division number of the small area displayed on this screen can be arbitrarily set within the business area. In addition, it is possible to display a grid on the map on this screen, so that you can check the state of the terrain that cannot be grasped only by text display. For this reason, there is also an enlarged display function for topography.

The display contents of the small areas constituting the mesh display screen W1 are the area name "Shinagawa north", and the "vehicle number" of the mobile station 4 which has entered the area first and is empty.
Also, the "number of vehicles" that are moving in the area while being vacant is prepared. The area displayed on the mesh display screen W1 can be switched by operating the page switching button of the mesh.

Detailed information of the mobile station 4 regarding each of these areas can be obtained in addition to the empty vehicle information screen W3 and the vehicle allocation recording window W4.
It is displayed on the dispatch allocation screen W5 and the specific waiting place display screen W6. Incidentally, these display screens are switched in response to a small area being selected by clicking the mouse. First, on the empty vehicle information screen W3, in addition to the vehicle number, the operating status, the traveling direction, and the number of dispatches are displayed.

Further, the vehicle allocation record window W4 is adapted to display the progress status of the vehicle allocation. Further, the vehicle allocation hold screen W5 displays the customer name for which the vehicle allocation has not been completed, the district name, and the reception time so that the operator can confirm the customer who has been waiting for a long time. By the way, for customers who have not been assigned a car for a certain period of time, the display color is reversed or a window is opened to call attention.

Further, the specific waiting place display screen W6 displays the specific waiting places (taxi stand, etc.) in the small area, the number of the vehicles lined up at the beginning, and the number of waiting vehicles. By the way, the waiting place can be set freely. Further, a history list W7 of the entire reception, dispatch information, etc. is displayed on the display screen of the display. Also, a plurality of special keys K1, K2, ...
Is provided. Here, the emergency call key K1 blinks at the time of an emergency call from a mobile unit, and is assigned a function of being connected to the radio by clicking.

Further, the fixed sentence sending key K2 is a key for the function of sending a message to a specific moving body. The voice key K3 is a key for realizing a voice call to a mobile body. Furthermore, 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. In addition, vehicle management, vehicle suspension, vehicle registration, printing, daily / monthly report printing functions are also provided. A map switching key K5 is a mesh / map switching key.

Finally, the reservation / acceptance screen W2 will be described. An example of the reception screen is shown in FIG. 5, and an example of the reservation screen is shown in FIG. In this field, if the customer name is registered when the customer's name is input, the boarding place and 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, if the customer name is not registered and the operator inputs a search for the town name, the destination, etc., the display method of the corresponding small area is changed.
That is, the color density and brightness are changed.

(2-2) Operation Procedure Next, the operation by the operator during vehicle allocation will be described. Here, FIG. 7 shows a schematic flow. Figure 8 shows the detailed flow
It is as follows. First, the operator receives a telephone call from the customer and confirms whether it is a reservation or immediate delivery (steps SP1 and SP2). If the vehicle is dispatched, the process proceeds to the customer search process (step SP3). At this time, the last 6 digits of the telephone number are searched. However, the name and address are also acceptable. If the customer information is already registered, the operator selects from the corresponding list. On the other hand, if it is not registered, it is confirmed by telephone and registered in the customer data.

Next, move to designation of district (step SP
4). In the case of a new customer, the cursor is moved to a small area corresponding to the corresponding area and the operation key of the mouse is clicked to select the area. The selected area is automatically registered in the customer database, and the area can be automatically specified the next time the customer is called. If there are no empty cars in the area,
Select from the regions with the highest number of empty cars among the eight regions diagonally above, below, to the left, right, and diagonally. In this case, make sure that the customer can be reached within 10 minutes. If there is no applicable vehicle in these 8 areas, the dispatch will be suspended. In addition, specific waiting areas are subject to the districts that include them.

When the designation of the area is completed, the next step is to call the car (step SP5). At this time, the corresponding vehicles in the designated area are displayed in the oldest order of the updated data (the order of entering the area first), and the mobile station 4 having the oldest data is automatically called. Incidentally, the mobile station 4 in the specific waiting place is also a target of the corresponding vehicle. When the corresponding vehicle is determined, the guidance sentence is transmitted (step SP6). At this time, the guidance sentence is transmitted as voice or data. That is, character data is transmitted by voice in the case of a new customer, and character data is transmitted in the case of a registered customer who has the same guidance text. By the way, a voice mail function is provided for sending this guidance sentence. When a customer requests a vehicle dispatch, this function selects the relevant area, but if there is no vacant vehicle in that area, a guidance text (voice) is recorded, and when the vacant vehicle enters the customer's dispatch area, it is automatically To send a guidance message to the empty car.

After that, the process proceeds to step SP7. If the mobile station 4 returns an acknowledgment (timeout is 5 seconds × 2), the customer is notified. If there is no response to this, the process moves to calling the next candidate mobile station 4. At this time, the vehicle allocation record (vehicle allocation number, time, customer name, telephone number) is automatically registered. When a response from the mobile station 4 is obtained, the process proceeds to step SP8 to notify the customer of the vehicle number and the estimated arrival time 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 GPS radio waves with a GPS antenna 4A integrated with a receiver.
The position information thus positioned is processed by the display-type controller 4B and sent to the modem / converter 4D which plays a central role in this system. Incidentally, the display type operation device 4B is provided with a card slot.
The information peculiar to the vehicle can be easily updated only by attaching / detaching the C card 4C to / from the card slot.

By the way, in addition to the vehicle specific information, the IC card 4C displays the guidance text received from the center station 2 on the screen if the moving speed of the mobile station 4 is below a certain speed and there is no response instruction from the crew. A program for controlling the display-type operating device 4B so that it cannot be displayed is written.

A speaker 4E and a wireless device 4F are connected to the modem / converter 4D in addition to the display type operation device 4B. As a result, it is possible to reproduce the voice captured via the antenna 4G via the speaker 4E, or to capture various instructions into the display-type controller 4B and display them on the display 4B1. Incidentally, the voice captured from the microphone 4I is transmitted from the antenna 4G via the radio 4F.

A charge meter 4H is also connected to the modem / converter 4D. This allows the modem / converter 4D to capture the operating state (FIG. 3) of the mobile station (taxi) 4 and, at the same time, to transmit the position information obtained from the GPS antenna 4A to the base station 3 from the antenna 4G. Has been done.

(3-2) Configuration of Modem / Converter 4D Next, the internal configuration of the modem / converter 4D is shown in FIG. The modem / converter 4D is mainly composed of the CPU 4D1. Here, a display type operation device 4B, a speaker 4E, a wireless device 4F, and a charge meter 4 which are externally connected to the modem / converter 4D.
H is directly or indirectly connected to the CPU 4D1.
The modem / converter 4D controls data transmission / reception with the base station 3 centering on the CPU 4D1.

As a structure peculiar to this modem / converter 4D, there is a memory 4D31 and a recording IC 4D32 provided in the demodulator 4D3. By using this recording IC 4D32, the vehicle 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 member of the mobile station 4 can confirm the content of the vehicle dispatch instruction as many times as necessary. Has been done. Therefore, it can be expected that more reliable vehicle allocation can be realized.

The modem / converter 4D has a voice digital control function. As a result, only the specific vehicle designated on the side of the center station 2
You can listen to the voice from.
This function can also enhance the confidentiality of customer information when dispatching a vehicle. In addition to the one-to-one call, the mobile station 4 and the center station 2 can switch between a call to a recruiting group (by sales office) and a broadcast (all vehicles). . Incidentally, all the switching can be arbitrarily performed on the side of the center station 2.

(3-3) Structure of 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 sequentially described. The call button 4B2 is a mobile station (taxi) 4
When an emergency such as an accident occurs, the button is provided for notifying the center station 2 of this in the highest priority. When this button is operated, transmission is continued regardless of the communication status of other taxis. This function can be canceled only from the center station 2. At this time, the crime prevention light does not blink. Furthermore, in order to prevent erroneous operation, a confirmation operation is added to the operation of this button.

Next, the area button 4B3 is a button provided for sequentially switching the business areas, and by operating this button, the specific waiting place displayed on the screen is switched. The charter button 4B4 is a button to be pressed when operating as a charter vehicle. Therefore, when canceling, the cancel button 4B17 may be pressed. The forwarding button 4B5 is a button to be pressed when taking a break. Similarly, when canceling, the cancel button 4B17 may be pressed.

The empty forecast button 4B is a button to be pushed when an empty vehicle is scheduled. Cancel button 4B17 to cancel
Press. The send button 4B7 is pressed to send a fixed message to the center station 2. When this key is pressed, a fixed message (FIG. 12) is displayed in a menu, and when the cursor is selected and the OK button 4B11 is pressed, transmission is started.

The receive button 4B8 is pressed to simultaneously display the two latest received messages. However, while running, no reception message is displayed even if this button 4B8 is pressed. An example of the reception message displayed at this time is shown in FIG. For this reason, when the “forgotten property inquiry” of “9” is received, “forget” is displayed on the screen. When the OK button 4B11 is pressed here, the contents shown in FIG. 14 are displayed for the first time.

Similarly, when "13""TrafficEnforcement" is received, "Communication" is displayed on the screen. When the OK button 4B11 is pressed here, the contents are displayed. When "14""Underconstruction" is received, "OK" is displayed on the screen. When the OK button 4B11 is pressed here, the contents are displayed. In addition to this, when an emergency message is received from the center station 2, an emergency contact screen as shown in FIG. 15 is displayed. To cancel these displays, the cancel button 4B17 may be pressed. 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, the contents of the guidance sentence are not displayed even if the button is pressed while running. When the user wants to delete the data, the cancel button 4B17 is pressed. In addition, charge meter 4H
The guidance sentence disappears even if you press the wage, surcharge, or payment. In addition, it disappears when a new guidance sentence is received. The OK button 4B11 is a button to be pressed when a vehicle dispatch request or a vehicle dispatch cancellation request is accepted.

The standby button 4B10 notifies the center station 2 of the current position or the specific standby location selected by the direction button ("←", "→", "↑", "↓") 4B18. The cancel button 4B17 is pressed to cancel a specific waiting place, forwarding, empty vehicle schedule, or reservation. It is also a button that is pressed to erase 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 Places In this example, a maximum of 36 specific standby places will be described for each business area. Day Play 4B1
Displays 12 specific waiting places of 3 columns x 4 rows at a time among the 36 specific waiting places allocated to the 6 columns x 6 rows square. A display example is shown in FIG. Incidentally, the name of the specific waiting place is represented by a maximum of 4 characters. In addition, the number of empty cars at each waiting place is displayed at the bottom of the table. By confirming this number, the crew can also move to a specific vacant waiting place.

Now, regarding the display screen of the display 4B1, the luminance (color) of the specific standby place closest to the latest position among the 12 specific standby places is displayed in reverse. This allows the crew to easily identify the closest specific waiting location at present. Further, when the specific waiting place closest to the latest position is out of the display area, the display area is automatically switched. By the way, it does not scroll. Incidentally, in addition to the automatic switching mode, a manual switching mode is prepared for switching the display area. In this case, the area button 4B3 may be pressed as described in the previous section, and at this time, the display area can be switched clockwise as shown in FIG.

(3-4-2) Specific Standby Place Setting Next, the setting of the specific wait place will be described. Normally, the nearest specific waiting place is highlighted. If the setting key is pressed here, the specific waiting place is registered in the center station 2. GP
If you want to set any specific waiting place, such as when you are in a place where S radio waves cannot be received, select it with the direction buttons (“←”, “→”, “↑”, “↓”) 4B18 and set it. be able to.

[0056] The cell (marker) highlighted here
Is located at the end of the currently displayed area, and when the direction button 4B18 is further pressed, the display area is automatically switched to the adjacent area. However, it does not scroll. However, if the setting key is not pressed even if the marker is moved, the marker is automatically returned to the nearest specific waiting place after 1 minute.

However, in this setting, the GPS radio wave is received, and the distance between the latest position and the nearest specific waiting place is 5
It cannot be set unless it is within the range of 00m. Further, the display can be canceled by pressing the cancel button 4B17 while the specific waiting place display is being performed.

(3-4-3) Vehicle dispatch instruction display and guidance text display When the mobile station 4 receives a vehicle dispatch instruction from the center station 2, an alarm sound is emitted to notify the crew member of the receipt of the vehicle dispatch instruction and the vehicle dispatch message is displayed. It is designed to be displayed above. If the vehicle is stopped, click OK button 4B here.
When 11 is pressed, the guidance sentence is displayed and the dispatch is completed.
On the other hand, when the user is traveling, even if the OK button 4B11 is pressed, the guidance sentence is not displayed in order to ensure safety in traveling. 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, the guidance sentence is displayed at that point. Also, when the vehicle is in a running state again, the guidance sentence is erased. By the way, the guidance sentence is designed to disappear when "fare", "extra", "payment" or "cancel" is pressed.

By the way, the judgment as to whether or not the vehicle is running is made based on whether or not the GPS speed is 10 km / hour or more. That is, it is determined that the vehicle is running when the speed is 10 km / h or more and is stopped when the speed is less than 10 km / h. However, if GPS radio waves cannot be received and it is impossible to determine whether or not the vehicle is running, it is considered that the vehicle is stopped and displayed. The above is the operation when the vehicle dispatch message is accepted, but even if the vehicle dispatch message is displayed, the OK button 4B is displayed.
If 11 is not pressed, the dispatch will be canceled in 10 seconds,
"The dispatch has been canceled." Is displayed on the display.

This display, that is, "the dispatch has been canceled." Disappears in 5 seconds. Also, when the cancel button or the OK button is pressed, it is also erased. Incidentally, the maximum length of the customer name displayed as shown in FIG. 18 is 26 full-width characters (13 characters × 2 lines), and the maximum length of the guide text is 65 full-width characters (13 characters × 5 lines). The state transition is shown in FIG.

(3-4-4) Display of current date and time and operating status of mobile station The contents to be displayed are "month", "day", "day of week", "hour",
Let's say "minutes". The time is set automatically by receiving GPS radio waves. It is possible to synchronize the built-in clocks of all mobile stations 4 by using GPS radio waves. The operating status of the mobile station 4 is always displayed. The contents are "standby", "forwarding", "kuyo" or "charter", and the display is "waiting", "times",
"Forecast" and "rent".

(4) Communication Protocol (4-1) Outline of Protocol In this system, there are three communication protocol layers as shown in FIG. That is, three layers are a physical layer (physical communication protocol), a link layer (protocol between units), and an application layer (protocol between applications). Originally OSI (Open System Interc
Onnection) is usually specified independently, but it is simplified to 3 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 assumed to be TTL-level asynchronous and full-duplex communication. It also controls transmission by CTS / RTS. In the physical layer “2”, FM narrow modulation wireless communication and baseband wired communication are performed in series. The wireless part is half-duplex, and the wired part is full-duplex. The physical layer "3" is assumed to be RS-232C level asynchronous and full-duplex communication.

On the other hand, the link layer "1" and the link layer "2"
Has an error detection function with a checksum and a retransmission function. The link layer "3" adds error correction and retransmission functions by BCH to HDLC.

(4-2) Link Protocol (4-2-1) AVM-Selector The features of this link protocol are that the communication capacity is minimized and the wireless error rate is taken into consideration. Can be corrected, in the case of a multi-bit error, the packet can be retransmitted, and the collision of a plurality of packets can be determined. Link packet tofu (M)
21 (based on DLC) is shown in FIG.

(4-3) Application Protocol (4-3-1) Calling Conditions from Mobile Station Finally, the calling conditions from the mobile station will be summarized and explained including the above items. The call origination timing common to all mobile stations 4 is when it crosses a grid boundary (mesh). This includes when you leave the area. However, it is possible to limit to only empty cars by setting the call condition from the center station 2. It is also possible to limit to only a specific mobile station 4.

Incidentally, the mesh interval can be changed from the center station 2. If you frequently cross the mesh,
A hysteresis width can be provided to reduce outgoing calls.
At this time, the mobile station 4 transmits the sub-mesh number and the approach direction to the mesh to the center station 2. However, if a transmission wait occurs due to busyton, the position at the time when transmission becomes possible shall be transmitted.

In addition to this, the following ten cases can be considered. When the state of the moving body changes (standby, empty car,
Real car). AC to command from center station 2
When K is returned (dispatch instruction, transmission of OK button to cancel dispatch, etc.). When the emergency message switch is pressed. When the emergency message button is pressed. Mobile station 4
When there is no call for a certain time (for example, 1 hour).

When the function of the mobile station 4 fails. When reporting the results of self-diagnosis. When requesting installation (including when repairs are completed). When sending fixed messages (forgotten items, no customers, accidents, etc.). When sending the packet resend count. Incidentally, 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.

(4-3-2) Contents of Transmission from Center Station Similarly, contents of transmission transmitted from the center station 2 to the mobile station 4 will be summarized and described including the above matters. First, dispatch request and cancellation of dispatch. Emergency call message transmission, free message transmission, fixed message transmission (forgotten items, accident, crackdown, etc.)
Etc. message. Set operating conditions and time. Self-diagnosis request and location transmission request. Cancel an emergency call. Installation completion notification. ACK for mobile station data (call suppression and cancellation requests are sent simultaneously). The number of vacant cars in a specific waiting area. These are road vectors and destination positions. Incidentally, 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.

(4-3-3) Operating conditions that can be remotely set from the center station First, the transmission conditions of the position (all vehicles, empty vehicles (empty forecast), specific ID,
It is possible to remotely control a specific group ID, area, and prohibition of all vehicles. Also, the mesh interval (2km, 1km ...) Can be changed. In addition, the regular transmission time and the effective range of the specific waiting place can be freely set. Furthermore, 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 individual ID of the mobile unit and the code of the group ID can be set. In addition, the range of the mesh (business area) and the name and position of a specific waiting place can be set remotely, and the contents of the fixed message can also be set. In this way, it is devised so that various conditions can be set as necessary.

[2] Second Embodiment In the first embodiment, the system in which the operator of the center station accepts the dispatch of vehicles and issues an instruction to each mobile station has been described. Of the telephone network control unit and the push-phone dial signal (hereinafter referred to as DTMF (Dual Tone Modulati)
It is also possible to construct a system in which a vehicle dispatching command is automatically issued to a mobile station if a customer or the like inputs a vehicle dispatching command by telephone from the outside.

Here, it is assumed that the same elements as those in the first embodiment are used among the elements constituting the system except the center station 12 shown in FIG. A new configuration of the center station 12 is a telephone network control device 2J provided between the private branch exchange 2H and the server 2D. The telephone network control device 2J realizes an interface between the customer who has issued the vehicle allocation request and the server 2D.

Next, the internal structure of the telephone network controller 2J is shown in FIG.
5 shows. The telephone network controller 2J is a network control unit (NC
U) Telephone line 2I (or private branch exchange 2 via 2J1)
H). The network control unit 2J1 gives the received DTMF sound to the DTMF detector 2J2,
The necessary message encoded by the encoder 2J3 is transmitted to the telephone line 2I.

The digital data converted by the DTMF detector 2J2 is taken into the CPU 2J4. CP
U2J4 is the telephone network control device 2 based on the captured information.
Manage J as a whole. The CPU 2J4 sends and receives necessary information to and from the server 2D based on the fetched data. For example, the customer number entered by the user and the inquiry result are CP
It is transmitted and received between U2J4 and the server 2D. If the inquiry result is correct, the vacant vehicle number and expected arrival time of the vehicle are sent and received. At this time, the serial interface 2J5 is used for transmitting and receiving data.

By the way, the response to the correctness of the number input by the user and the message regarding the vehicle allocation information (the empty vehicle number for which the vehicle allocation instruction is issued and the expected arrival time) are registered in the incoming / guidance message memory 2J6, and the response to the user is given. When it becomes necessary, a command signal is output from the CPU 2J4 to the incoming call / guidance message memory 2J6. Incoming call / guidance message memory 2J6
The data output from the encoder is encoded via the encoder 2J3 and output to the network control unit 2J1.

In the above configuration, the telephone network control device 2J
A description will be given of an automatic vehicle allocation processing procedure capable of realizing the unmanned operation of the center station 2 with a focus on the processing of. 25 to 27 show a series of processing procedures by the telephone network control device 2J. When the customer dials a telephone number prepared for automatic dispatch, the customer's telephone is connected to the telephone network control unit 2J via the private branch exchange 2H of the center station 2. Telephone network control unit 2J
Uses the DTMF detector 2J2 to decode the DTMF sound captured via the network control unit 2J1, and the CPU 2J4
Give to.

When the CPU 2J4 confirms the call of the customer in step SP1, the CPU 2J4 moves to step SP2 and instructs the call reception / guidance message memory 2J6 to send the response message. At this time, the CPU 2J4 sends an announcement such as "This is a XX taxi dispatch center. Please press your registration number and press # at the end." To the customer terminal connected through the telephone line 2I. At the same time, the CPU 2J4 waits for the customer to input the registration number via the telephone line 2I.

When the completion of the input is determined, the processing of the CPU 2J4 shifts from step SP3 to the processing of step SP4 to determine whether or not there is an input error. Incidentally, the input error here is a difference in the number of digits of the input registration number or an input error of a specific character (for example, * is input instead of #).
If there is an input error, the CPU 2J4 obtains a positive result, moves to the processing of step SP5, and instructs the incoming call / guidance message memory 2J6 to send a response message. At this time, the CPU 2J4 sends an announcement such as "There is an error in input. Please input again and press #" to the customer side terminal connected via the telephone line 2I. Incidentally, after this, the processing procedure of the CPU 2J4 returns to step SP3.

On the other hand, if there is no input error, C
The processing of PU2J4 is performed from step SP4 to step SP6.
Then, the process moves to the confirmation message sending process. At this time, an announcement such as, for example, "Your registration number is 12345, please press # if you are okay, please press * if you made a mistake" is sent to the terminal on the customer side via the telephone line 2I.

Subsequently, the CPU 2J4 proceeds to step SP7 and proceeds to the processing for determining whether or not # has been pressed (that is, whether it is a correct number). If a negative result is obtained here, the CPU 2J4 moves to step SP8 and moves to a message sending process prompting re-input of the registration number. At this time, an announcement such as "Please re-enter and press #" is played to the customer terminal via the telephone line 2I.
After that, the processing procedure of the CPU 2J4 returns to step SP3.

On the other hand, if a positive result is obtained at step SP7, the CPU 2J4 proceeds to step SP9. At this time, the CPU 2J4 connects to the server 2D through the serial interface 2J5 and searches the database to search for the customer with the input registration number. When the search is completed, the process proceeds to step SP10. CPU2
J4 shifts to the determination process of whether or not the corresponding number is found,
When a negative result is obtained, an announcement of, for example, "The customer with the number 12345 is not applicable" is sent to the terminal on the customer side via the telephone line 2I, and the re-input confirmation mode of step SP11 is entered. The processing in this mode will be described later.

On the other hand, if a positive result is obtained at step SP10, the CPU 2J4 proceeds to the processing at step SP12 and confirms the corresponding information by sounding. For example, "○○
It is like that. Press # if you like, or * if you made a mistake. , And move to step SP13. In step SP13, it is determined whether or not # is pressed. If a negative result is obtained, step SP1
Move to 4 and move to re-input confirmation mode.

On the other hand, when a positive result is obtained in step SP13, the CPU 2J4 moves to step SP15 and accesses the database 2D1 via the serial interface 2J5 and the server 2D to search for an empty car closest to the customer position. When the search is completed, the vehicle number of the vacant vehicle and the predicted arrival time are obtained, and this is transferred to the response message transmission processing at step SP17. At this time, an announcement such as "Car 678 will be coming in 5 minutes. Thank you for using." Will be played on the customer terminal. Then, in step SP18, the connection of the telephone line is cut off, and a series of processing procedures are completed.

Incidentally, the process of the re-input confirmation mode described above is shown in FIG.
It is as follows. When the processing is started from step SP21, the process moves to step SP22 and a response message is output. As this message, for example, "Are you sure you want to input again? If you want to input again, please press #, and if you want to cancel, please press *". CPU2
After sending this announcement to the customer side, J4 waits for the customer's decision. After this, the CPU2J4 makes a step S
Moving to P23, it is determined whether or not # is pressed. If a positive result is obtained here, the process returns to step SP3. On the other hand, if a negative result is obtained, the process moves to step SP24 to play a response message. Here, for example, "Thank you for using." Is flown, and the processing is terminated by disconnecting the telephone line at the next step SP25.

As described above, the center station 12 is provided with the automatic start-type telephone network control unit 2J1 and the DTMF detector 2J2 which is a recognition unit for the push-phone dial tone transmitted from the push-phone telephone in the terminal of the center station. The number of personnel on the center station side can be reduced by automatically issuing a vehicle dispatch command to the mobile station if a customer or the like inputs a vehicle dispatch instruction by telephone from the outside. Moreover, since the line occupation time and the processing time can be significantly reduced as compared with the case where the vehicle dispatch is accepted via the operator, the vehicle dispatch efficiency can be improved.

[3] Third Embodiment Finally, an example of a vehicle allocation system in which the radio occupancy time is shortened and the system capacity is improved will be described. Therefore, in the embodiment, not the voice but the text data is used for the communication from the base station 3 (center station 2) to the mobile station 4. This shortens the line occupation time. Then, the mobile station 4 side is provided with conversion means for converting the received text data into voice.

FIG. 29 shows an example of the interface unit. The modem / converter 14D of FIG. 29 is one of the modifications of the modem / converter 4 shown in FIG. First, the schematic configuration of the modem / converter 14D will be described. The signal received by the radio 4F is demodulated via the modem 14D2 and then fetched by the CPU 14D1. Also radio 4
In addition to this, the signal received by F is input to the collision prevention signal detector 14D3 and the speaker control signal detector 14D4. The CPU 14D1 controls the switch SW2 according to whether the received signal is addressed to itself or not, and controls the switch SW1 based on whether the received signal is an analog voice signal or text data.

At this time, when the data received via the radio 4F is addressed to itself and is an analog voice signal, the voice received by the radio 4F is the switch SW1 whose terminal is switched to the black circle side and It is output to the speaker 4I via the switch SW2 and the amplifier 14D6. on the other hand,
When the data received via the wireless device 4F is text data addressed automatically, the terminal of the switch SW1 is switched to the white circle side, and after being taken into the CPU 14D1 via the modulator 14D2, the Japanese language processor 14D7, rule. The analog voice signal converted into the analog waveform via the voice synthesizer 14D9 is output to the speaker 4I via the switch SW2 and the amplifier 14D6.

Here, the Japanese language processor 14D7 operates to refer to the dictionary memory 14D8, convert the text data fetched from the CPU 14D1 into a phonetic symbol string, and give it to the regular speech synthesizer 14D9. The regular speech synthesizer 14D9 operates to convert the captured phonetic symbol string into an analog speech waveform by using the phoneme waveform data memory 14D10. The various instruction statements transmitted in the form of text data by these processing circuits are notified to the managing officer as voice. Incidentally, the content of the text data is also displayed as characters on the display type operation device 4B.

The modem / converter 14D is provided with an amplifier 14D11, a speaker control signal generator 14D12, an adder 14D13, and a switch 14D14 for communication from the mobile station 4 to the base station 3 (center station 2). Cage,
The voice of the mobile station 4 can be transmitted to the center station by using these circuits. Modem with the above configuration /
If the converter 14D is used to send and receive necessary information in the form of text data, the communication time can be shortened and the line capacity can be improved.

In this example, the case where the communication text from the center station to the mobile station side is transmitted as text data has been described, but the present invention is not limited to this, and the text is also used for communication from the mobile station side to the center station side. The use of data can further improve the line capacity.

[4] Other Embodiments In the above-mentioned embodiments, the taxi management system using the taxi as the mobile station 4 has been described, but the present invention is not limited to this, and the transportation management system is intended for pickup and delivery trucks. Can also be applied to. Further, the present invention is not limited to this, and may be used as a staffing management system.

Furthermore, the following communication method may be adopted as the communication method of this mobile unit management system without being limited to the above embodiment. For example, when controlling the transmission timing of each mobile station based on a synchronization signal transmitted from a base station (center station), synchronization is performed based on a GPS synchronization signal received by a GPS receiver mounted on the mobile station. The timing may be interpolated.

By doing so, the synchronization timings of all mobile stations can be made substantially coincident. Furthermore, if this function is used, the following control is also possible. That is, it is also possible to divide a plurality of mobile stations into groups and manage the period during which each group can communicate with the base station.
By doing so, the probability of simultaneous calls 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 having the same radio frequency as that of the data communication, a specific tone or control code is transmitted from the center station, and the mobile station receiving the tone transmits a specific tone or control code. It is also possible to stop the call and not disturb the voice call.

As a method of transmitting voice and data in parallel, the input voice information is digitized and temporarily held, so that communication control information such as ACK for the vehicle is sent in advance. It is also conceivable to play back and send the sound after that.
