[0011]

FIG. 1 is a block diagram showing a map information input device according to the present invention. Hereinafter, a description will be given of an example in which the map information input device is used in a logistics business for delivering goods to a designated destination and is applied to a device for inputting the destination. This device is roughly composed of a central control unit 1 provided at a distribution center, which is a distribution base, and a terminal 2 provided on a moving vehicle for delivery. The positions of the central control unit 1 and the terminal 2 are detected by satellite positions. It can be obtained by means 3.

The satellite position detecting means 3 is a GPS satellite 3
GPS receivers 3b and 3c that can check the latitude and longitude by receiving radio waves from a (GPS; Global Positioning System)
Consists of The GPS satellites 3a are provided at a plurality of locations in the sky as shown in the figure, and the GPS receiving means 3b and 3c can obtain the position based on the reception time difference between the plurality of radio waves.

The central control section 1 has a delivery information section 5a for storing delivery information to a destination, a map information section 5b for storing map information, and a control means 12 for performing data processing described later. The delivery information section 5a stores input information N for each destination as shown in FIG. 2 as delivery information of the destination. The input information N is a code number for each destination,
The information includes a name, an address, a delivery item, a quantity, and the like, and is information transmitted from a newly generated delivery destination.

The destination information W corresponding to the input information N of the delivery information section 5a is stored in the map information section 5b as shown in FIG.
Is stored. Current position conversion means 1 via communication means 10
1 converts the input latitude and longitude information of the terminal 2 into an XY coordinate axis format on a map. This current position is used as destination information W as described later.

The control means 12 reads the input information N of the destination from the delivery information section 5a, and reads the current position conversion means 1
When the destination information W of the terminal 2 is inputted from 1, the destination information W is stored again in the map information section 5 b by the position setting means 13. Here, in the destination information W, the destination corresponding to the destination is stored in the XY coordinate format. However, at the stage where only the input information N of the destination is input from the input unit 20, the destination information W is blank. is there.

The mobile terminal position correcting means 14 corrects the latitude and longitude output errors of the satellite position detecting means 3. The latitude and longitude of the central control unit 1 obtained by the GPS receiving unit 3b provided in the central control unit 1 are likely to have errors with respect to the latitude and longitude on an actual map. Therefore, the latitude and longitude of the central control unit 1 previously measured on the map are set in the mobile terminal position correcting unit 14, and the set values and the GPS receiving unit 3b of the central control unit 1 are obtained. The difference between the obtained latitude and longitude is obtained, and the position error of the central control unit 1 is corrected. This calculation is performed every predetermined time, that is, GPS
This is performed every time the latitude and longitude are obtained by the receiving means 3b, and the difference between the latitude and longitude is individually calculated and constantly updated.

This difference is used to correct the position of the terminal 2 when a specific request for the terminal 2 described later is made. That is, the mobile terminal position correcting means 14 corrects the position error of the terminal 2 based on the following formula: mobile station current position = mobile station GPS latitude / longitude- (fixed station map latitude / longitude-fixed station GPS latitude / longitude). Although the latitude and longitude are described in one equation in the above equation, the latitude and longitude are actually calculated separately. The fixed station corresponds to the central control unit 1, and the map latitude and longitude are true fixed values indicating the latitude and longitude actually measured on the map,
The GPS latitude / longitude is a fluctuation value including a position error indicating the latitude and longitude received by the GPS receiving units 3b and 3c.

The central control unit 1 includes a display output unit 1.
5 are provided to output delivery information and map information. The display output means 15 comprises an image display such as a CRT or a printer.

The terminal 2 is connected to the central control unit 1 via a wireless communication unit 25 between the communication units 30 and 10. When the input key 31 of the terminal 2 is pressed, this terminal 2
Sends a request to the current position conversion means 11 to generate a current position (destination information W). The input key 31 transmits input information N such as a destination code. At the same time, the GP of terminal 2
The latitude and longitude of the terminal 2 are transmitted by the S receiving means 3c.

The wireless communication between the terminal 2 and the central control unit 1 can be configured so that data can be transmitted and received between them. In this case, the display output means 32 is also provided on the terminal 2 side, and the central control unit The delivery information and the map information can be transmitted from one side, and the information can be displayed and output by the display output means 32.
The terminal 2 has a terminal control means 33 for controlling the terminal 2.
Is provided.

Next, input of a destination according to the above configuration will be described. As an example of this input, it is assumed that input information N of a plurality of destinations is input to the central control unit 1 in advance, and the terminal 2 sequentially moves along a predetermined delivery route connecting the plurality of destinations. Shall go. And
In the central control unit 1, the difference between the latitude and longitude on the map and the latitude and longitude obtained by the GPS receiving means 3b is set in the mobile terminal position correction means 14 (calculation setting in parentheses in the above formula).

When the terminal 2 moves, the GPS receiving means 3c mounted on the terminal 2 obtains the latitude and longitude of the terminal 2. Then, when the terminal 2 is moved to the destination, the input key 31 is pressed (at this time, a code number corresponding to the corresponding destination may be input).
, The latitude and longitude are transmitted via the wireless communication unit 25, and the current position (XY coordinates) is created by the current position conversion unit 11.

At this time, the mobile terminal position correcting means 14 obtains the difference from the above equation, and corrects the position error of the terminal 2 included in the GPS device. Here, the central control unit 1
On the side, the position error of the central control unit 1 is corrected every predetermined time, and as a result, the current position of the mobile station (the position of the terminal 2) is corrected every predetermined time as shown in the above equation, and the accuracy is improved. You can do it. This is based on the fact that the position error generated by the central control unit 1 and the position error generated by the terminal 2 are substantially equal as viewed from the GPS satellite 3a. The control means 12 reads out the input information N of the destination corresponding to the code number. Thereafter, the control unit 12 re-stores the destination information W characterized in the XY coordinate axis format in the blank destination information W portion corresponding to the input information N.

Thus, the destination information W for the input information N
Can be stored in pairs, and thereafter, in the central control unit 1,
Just enter the code number or name of the destination,
The location of the destination can be searched on a map.

Next, an example of outputting map information by the display output means 15 of the central control unit 1 at the time of map search will be described. The contents of this map search are basically the same as the contents described in the specification of the map search device filed earlier. That is, as shown in FIG. 3, a basic diagram 50 formed of a flexible transparent film having a horizontal width L1 and a vertical width L2 for each predetermined area.
Prepare On the basic diagram 50, map information S1 such as roads, lane markings, town names, and target names in the area are displayed as lines, frames, and characters at a predetermined scale ratio. The basic diagram 50 uses, for example, an atlas printed on a transparent film by OHP or the like.

Then, as shown in FIG.
From the page printer or roll printer as No. 5, the output figure 60 is mainly printed on recording paper such as paper.
The output diagram 60 has the same horizontal width L1 and vertical width L2 as the basic diagram 50.
Having. On this output diagram 60, the location information S2, which is the content of the destination information W corresponding to the input information N, is output at the same scale ratio as that of the basic diagram 50, and the destinations A, B,
The position information S2 is printed and displayed at the location C. Also, at each of the destinations A, B, C,..., A code number of the input information N or information S3 indicating a delivery order is printed. Then, as shown in FIG. 5, by overlaying the basic diagram 50 on the output diagram 60, the destination A,
The positions of B, C,... Can be known on the map.

Here, the destination information W stored in the map information section 5b stores the position of the destination as a character in the XY coordinate format, and stores all the information described in the atlas (for example, Since the data is not stored in the form of an image, no burden is imposed on the CPU constituting the control means 12, and the processing speed can be increased. At the same time, the memory capacity of the map information section 5b can be reduced.

As a modification, the location information S2 of the destination can also be obtained by using an atlas or the like as the basic diagram 50 and overlaying a transparent output diagram 60 thereon. Further, in addition to using the above-described printer as the display output unit 15, a configuration in which an image is displayed on a CRT may be adopted. In this case, the basic diagram 50 and the output diagram 60 may be configured to display an image on the CRT. .

Next, a modification of the above embodiment will be described. The terminal 2 in the above embodiment has been described as a configuration for issuing a request for the current position generation to the central control unit 1 via the satellite position detecting means 3 every time the input key 31 is pressed.
May be provided with a distance measuring means 35 and a time measuring means 36 shown in FIG. The distance measuring means 35
It measures the moving distance of the vehicle on which the terminal 2 is mounted, and electrically measures the distance from the number of rotations of the wheels of the vehicle.

Therefore, when the vehicle is delivering along a predetermined delivery route and the input key 31 is pressed when the vehicle reaches a certain destination, the distance measuring means 35
Measures the distance moved since the last time the input key 31 was pressed. At the same time, the timing means 36 measures the travel time spent on the travel distance. Therefore, by traveling around a plurality of destinations, the travel distance and travel time from the previous destination are measured each time the destination is reached.

Each time the input key 31 is pressed from the terminal control means 33, the moving distance and the moving time are stored in the wireless communication means 2.
5 is transmitted to the central control unit 1 side. Therefore, the central control unit 1 can obtain the distance and time between each destination as well as the location of the destination. Note that the moving distance and the moving time may be stored in the memory 37 of the terminal 2 and may be directly connected to the central control unit 1 and transferred later.

The moving distance and moving time between each destination in the delivery route are determined by the dynamic type physical distribution automatic navigation device 40 connected to the central control unit 1 side.
(Application by the same applicant as the present application; Japanese Patent Application No. Hei 5-13484)
No. 3) or a dynamic automatic dispatching system (Japanese Patent Application No. Hei 5)
-134842). That is, the apparatus minimizes a delivery route that connects a plurality of destinations where a plurality of destinations can be considered by changing the route, using the input travel distance and travel time as parameters. In the apparatus, each destination is a node, and the destinations are linear links. The shortest delivery route is simulated by reconnecting the nodes.

[0033]

According to the present invention, the input of the position into the map information of the destination is performed by the terminal moving to each destination, and the destination information obtained by detecting the position of the terminal by the position detecting means is obtained. Is stored in the map information section so as to be paired with the input information, so that the position of the newly generated destination on the map can be input easily and easily. Therefore, even when there are many destinations to be input, this input operation can be performed quickly and efficiently by the terminal sequentially moving to each destination. Also,
After inputting the destination information, the position of the corresponding destination on the map can be obtained at the same time simply by inputting the input information such as the destination name to the device.

In the input operation and the subsequent search operation, the destination information is processed in the form of a character in the form of XY coordinate axes. As a result, the calculation load is reduced and the calculation speed can be increased. Also, when the difference between the position error detected by the satellite position detecting means and the true position on the map for the fixed central control unit is stored, the position of the moving terminal is obtained by the satellite position detecting means. By adopting a configuration in which correction is performed using this difference, it is possible to accurately obtain the position of a moving terminal without error even when using a GPS whose terminal position detection accuracy is low. Furthermore, if the terminal is configured to measure the moving distance and the moving time together with the request for generating the position each time the input key is pressed when the terminal is moved, in addition to the position of the destination on the map, the distance between the destinations Since the distance and time can be obtained at the same time, when creating a delivery route for sequentially delivering destinations after inputting the map information, the delivery time and the like are created by referring to the measured travel distance and travel time. Will be able to do it.
