2. Description of the Related Art Conventionally, the problems to be solved by the invention
In the case of courier delivery, the driver of the delivery truck (the courier) generally delivered the map while looking for the delivery destination with one hand. However, in this case, if the place name or the like is not known, it is difficult to find the place of the delivery destination or it takes time to search. It is also possible to find out the optimal / shortest delivery route in advance and enter it on the map so as not to do so, but finding the optimal / shortest delivery route itself requires abundant experience. .

Further, despite such efforts before delivery, mistakes such as delivery omission or forgetting to deliver may occur, and in such a case, the user may go twice in the same direction, resulting in very poor delivery efficiency. In addition, wasteful exhaust gas is emitted, which also contributes to pollution. The causes of these are that the conventional home delivery system itself depends in large part on the experience of the home delivery worker. Therefore, it takes time for a newcomer to become a full-fledged person.

Therefore, the present invention has been made in view of the above problems, and even a inexperienced courier can set a delivery route in the same manner as an experienced worker, and misses delivery or forgets to deliver. It is an object of the present invention to provide a home delivery navigation system that can be effectively prevented.

[0005]

The home delivery navigation system of the present invention, which has been made to achieve the above object, stores information about delivery and stores the delivery stored in response to an inquiry signal from an interrogator. A home delivery navigation system using an electronic tag equipped with a response circuit for transmitting information, wherein when the delivery information is stored in the electronic tag, the location information of the delivery destination is set in the latitude and longitude corresponding to the positioning information used for radio navigation. The vehicle used for home delivery along with input
The present position of the own vehicle is detected by the radio navigation, and a navigation means capable of displaying the present position on a map displayed on a display device inside the vehicle is provided, and is read from the electronic tag and input to the navigation means. Among the delivery information, at least the location information of the delivery destination can be displayed on the map displayed on the display device.

As a method of reading the delivery information from the electronic tag and inputting it to the navigation means, for example,
A method of individually reading and inputting with an interrogator when loading luggage with electronic tag attached, or storing delivery information collected collectively at the time of sorting of luggage in an IC card, CDROM, etc., and using it A method of inputting into the navigation means of the vehicle can be considered.

Further, the navigation means selects one of the delivery destination position information displayed on the map which is the closest to the current position of the own vehicle, and the other delivery position information of the closest delivery destination is selected. It may be configured to be displayed so as to be distinguishable from the position information. Furthermore, the navigation means is configured to be able to arbitrarily select and instruct the next delivery destination among the position information of the delivery destination displayed on the map, and the electronic tag is attached. When the parcel is unloaded from the delivery vehicle, if the delivery information read from the attached electronic tag corresponds to the position information designated as the selection, the position information designated as the selection on the map is displayed. It may be configured such that it is displayed or erased so as to be distinguishable from other position information, and on the other hand, if it does not correspond to the position information selected and instructed, a warning is issued.

[0008]

According to the home delivery navigation system of the present invention having the above configuration, at least the delivery destination among the delivery information read from the electronic tag along with the current position of the vehicle is displayed on the map displayed on the display device of the navigation means. The location information of is displayed. Since the delivery destination can be successively shown to the worker in this manner, for example, even an inexperienced courier worker can gain experience by looking at the own vehicle position and the delivery destination position on the map. The delivery route can be set as much as that of workers, and it is possible to effectively prevent missed deliveries and missed deliveries.

Further, among the position information of the delivery destination displayed on the map, if the position information closest to the current position of the own vehicle is displayed so as to be distinguishable from other position information, the delivery is performed accordingly. You can do more effective delivery just by going. Furthermore, when the package is unloaded from the delivery vehicle, if the delivery information read from the affixed electronic tag corresponds to the position information selected, the position information selected on the map If it is displayed or erased so that it is indistinguishable from the location information on the other hand, and if it does not correspond to it, a warning is issued so that if the wrong package is unloaded, it can be found immediately and the position related to the delivered package The information and the positional information of the packages to be delivered are not confused, and it is more effective in preventing mistakes in delivery and forgetting to deliver.

The GPS receiver 17 receives a signal radio wave transmitted from a GPS transmitter (not shown) mounted on the GPS satellite 80.
It has an antenna 19.

These sensors 11, 13, 15, 17
Since each has an error of a different property, it is configured to be used while being interpolated by a plurality of sensors. Depending on the accuracy, it may be configured by a part of the above, and further, a rotation sensor for steering, a wheel sensor for each rolling wheel, etc. may be used.

The map data input device 2 is a device for inputting so-called map matching data for improving the accuracy of position detection, and various data including map data and route guidance. As a medium, CDR is
The OM is generally used, but other media such as a memory card may be used.

The display 7 is the driver's seat 10 of the delivery vehicle 100.
The position detector 1 is installed on the display 7.
It is possible to display the position information of the vehicle input from the vehicle and the navigation map NM input from the map data input device 2 in an overlapping manner (see FIG. 1B). The navigation device 60 also has a so-called route guidance function of displaying a representative route from the current position to the destination when the destination is input by the operation switch 3. As the operation switch 3, for example, a touch switch integrated with the display 7 or a mechanical switch is used, and is used for various inputs.

On the other hand, the interrogator 70 is attached to the door 103 of the freight compartment 101 of the delivery vehicle 100 in this embodiment, and an interrogation signal is sent to the courier slip 21 as an electronic tag attached to the luggage 25. Is emitted and the delivery information stored therein is transmitted.

First, the courier slip 21 will be described.
This courier slip 21 is, as shown in FIG.
A plurality of slip pieces 22 such as a delivery slip and a copy of the delivery destination are united by binding them at their ends, and a handwritten entry field is attached to the slip piece 22 attached to the parcel 25 (FIG. 1A). Two
3 and a response circuit 24 are formed.

The handwritten entry field 23 is a portion in which, in addition to the information such as the delivery destination and the shipping origin, the sorting code indicating the arrival at the store, the fee, etc. are entered by handwriting. The response circuit 24 is composed of an antenna 30 for exchanging data, an IC 31 for controlling the circuit and storing delivery data, and a battery 32 for supplying electric power to the IC 31. Sorting code indicating the delivery area is 25
It is input at the time of the agency.

Next, the electrical structure of the response circuit 4 is shown in FIG.
It will be described based on. As shown in FIG. 4, the response circuit 24
The IC 31 provided in the device includes a modulator 44, a demodulator 45,
Level comparator 46, CPU 47, clock generator 48,
A memory 49 is built in. The level comparator 46 includes an operational amplifier 46a, compares the voltage of the output signal of the demodulator 45 with a reference voltage, and connects the battery 32 to the CPU 47 and the clock generator 48 if the voltage of the output signal is higher than the reference voltage. Have. The memory 49 stores the received data in addition to the program executed by the CPU 47.

The response circuit 24 operates as follows. The demodulator 45 extracts the interrogation signal from the radio wave received by the antenna 30. The interrogation signal is the level comparator 46 and the CPU
It is output to both 47. The level comparator 46 compares the voltage level of the output signal of the demodulator 45 with the reference voltage. When the voltage of the output signal of the demodulator 45 is higher than the reference voltage, the battery 32 is connected to the CPU 47 and the clock generator 48.
, The CPU 47 and the clock generator 48 are activated. When activated, the CPU 47 executes the program stored in the memory 49 based on the clock.

If the received data output from the demodulator 45 is data such as a destination, the received data is stored in the memory 4
9 is stored. On the other hand, if the received data is a request command for data such as a destination, the CPU 47 executes a program stored in advance in the memory 49, reads the data stored in the memory 49, and outputs a signal corresponding to the data to the modulator 44.
Output to. The diode 44a of this modulator 44 is C
The conduction / non-conduction changes depending on the signal output from the PU 47. Therefore, by changing the impedance in this way, the interrogator 70 used at the time of sorting which will be described later.
(Fig. 3) Modulates radio waves from the antenna 30
Send more.

Next, the interrogator 70 which radiates a radio wave toward the response circuit 24 and takes out delivery data will be described. As shown in FIG. 5, the interrogator 70 includes a carrier oscillation circuit 51 that creates a carrier wave of a transmission wave, a modulator 52 that superimposes information on the carrier wave, a circulator 53 that separates a transmission wave and a reception wave, and a radio wave. The transmission / reception antenna 54 is an entrance / exit, a demodulator 55 that extracts information from a received wave, and a signal processing unit 56 that controls the modulator 52 and the demodulator 55 to process information. The signal processing unit 56 includes a CPU 57 that performs information processing and communication with the outside, and a CPU 57.
It comprises a clock generator 58 for supplying an operating clock. The interrogator 70 is connected to the navigation device 60.

Next, the operation of the interrogator 70 having the above-mentioned circuit configuration will be described. The transmission wave from the interrogator 70 is generated by modulating the carrier wave generated by the carrier oscillation circuit 51 by the modulator 52. That is, the data transmitted from the signal processing unit 56 to the modulator 52 is superimposed on the transmission wave.

The transmitted wave thus created is sent to the circulator 53, from which it is sent to the transmitting / receiving antenna 54 and radiated into the air. Then, if a response signal is returned from the response circuit 24 of the courier slip 21, it is received by the transmitting / receiving antenna 54. The received wave is sent to the demodulator 55 via the circulator 53, where the information contained in the received wave is extracted and sent to the signal processing unit 56 for processing.

The signal processing unit 56 receives the control signal and various information input from the external interface 61, sends the transmission data to the modulator 52, and further demodulator 55.
From the response circuit 24 and outputs it to the external interface 61. These data are input to the CPU 5 of the navigation device 60.

Next, the procedure of home delivery work using this system and the flow of information accompanying it will be described with reference to FIG. First, a voucher (not shown) at a home delivery agent
Is used to enter delivery position information (for example, address) in the courier slip 21 in correspondence with the GPS information in latitude and longitude. Also, other data such as sorting information and ID information is input at the same time. Then, the courier slip 21 in which the data is input is attached to the luggage 25.

The parcels 25 to which the parcel delivery slip 21 is attached are collected at the distribution center and are automatically sorted by a sorter (not shown) based on the sorting information in the parcel delivery slip 21. Next, when the luggage 25 is loaded into the delivery vehicle 100, the interrogator 70 installed on the door 103 of the cargo room 101.
Then, the delivery position information and other information (for example, ID information) are read from the home delivery slip 21 attached to the parcel 25. The read information is displayed on the navigation map NM on the display 7 of the driver's seat 105 as the delivery position instruction mark M1 of the loaded luggage 25. On this navigation map NM, it is transmitted from the GPS satellite 80,
GP received by the GPS antenna 19 of the delivery vehicle 100
The current position of home delivery vehicle 100, which is measured based on the S signal or the like, is displayed as current position display mark M2.

After the parcel 25 that has been read is loaded on the delivery vehicle 100, the delivery 25 proceeds to the delivery. The driver (delivery worker) heads to the destination while looking at the navigation map NM on the display 7. At this time, based on the current position of the delivery vehicle 100 and the delivery position information regarding many packages 25 input to the navigation device 60, the delivery position instruction mark M1 closest to the current position is distinguished from the other delivery position instruction marks M1. It is more effective to display with a mark. As a method of distinguishing, for example, the color or shape of the mark may be changed (see FIG. 1B) or may be blinked.

Further, by operating the operation switch 3 of the navigation device 60, the contents (delivery destination name etc.) of the package 25 corresponding to the above-mentioned distinguished home delivery position instruction mark M1 are displayed on the display device 7. Good. In addition, considering that the delivery efficiency is not necessarily good if only the items closest to each other in terms of distance are delivered in order,
When designating the delivery position instruction mark M1 indicating the contents of
The designated candidate marks may be moved in order by a predetermined operation with the operation switch 3.

When reaching the destination, the luggage 25 is delivered to the home delivery vehicle 1.
It is taken off from 00. At this time, the door 1 of the cargo room 101 again
The interrogator 70 installed in 03 reads the delivery position information and ID information from the home delivery slip 21 attached to the parcel 25, and sends the information to the navigation device 60.

In the navigation device 60, if the read delivery information corresponds to the home-delivery position instruction mark M1 selected and instructed, the home-delivery position instruction mark M1 selected and instructed on the navigation map NM is delivered. It is displayed so as to be distinguishable from the other home delivery position instruction marks M1 or erased so that it can be seen that it has been completed. The state in which the home delivery position instruction mark M1 is selected and instructed here means that, for example, if the contents of the package 25 corresponding to the home delivery position instruction mark M1 are indicated on the display 7, the selection instruction is automatically made. It can be considered to be in a state.

On the other hand, if the read delivery information does not correspond to the home delivery position instructing mark M1 selected and instructed, a warning is issued by an alarm (not shown). By doing this, it is possible to find the wrong package 25 immediately when it is unloaded, and the delivery position instruction mark M1 for the delivered package 25 and the delivery position instruction mark M1 of the package 25 to be delivered are confused. Instead, it is more effective in preventing missed deliveries and missed deliveries.

It is to be noted that when, who, where, and which parcel 25 is unloaded is stored in an IC card or the like and is downloaded to the host computer in the distribution center when returning to the distribution center, if necessary at a later date, You can easily trace a specific baggage.

The above is the work procedure and the flow of information, but in order to make it easier to understand, the flow chart shown in FIG. When the power is turned on and the operation is started (step 100), the GPS signal is received (step 11).
0), the navigation map NM indicating the current position is displayed on the display 7 (step 120). And luggage 2
When the delivery position information and ID information read by the interrogator 70 when loading 5 are input (step 13
0), based on that information, navigation map NM
A delivery position instruction mark M1 corresponding to the loaded luggage 25 is displayed on the top (step 140). This step 1
The processes of 30 and 140 are performed until all the loads 25 are loaded.

After the loading of the parcels 25 is completed, when a switch or the like (not shown) for instructing the end of loading is operated to determine that the loading is completed (step 150), the delivery position instruction mark M1 closest to the current position is changed to another delivery position. It is displayed so that it can be distinguished from the instruction mark M1,
The contents of the package 25 (delivery destination name, package information, etc.) corresponding to the home delivery position instruction mark M1 are shown on the display 7 (step 160). Since it has already been described that the designation of the home delivery position instruction mark M1 indicating the contents of the luggage 25 can be arbitrarily changed by the operation of the operation switch 3, it is omitted here.

At the destination, the luggage 25 is delivered to the home delivery vehicle 10.
When the delivery position information and the ID information read by the interrogator 70 are input when being unloaded from 0 (step 170), does the read information correspond to the home delivery position instruction mark M1 that is selected and instructed? It is determined whether or not (step 180). If it corresponds (step 180: YE
S) The home delivery position instruction mark M1 selected and instructed is erased from the navigation map NM and stored in the IC card (step 190). Instead of deleting, it may be displayed so as to be distinguishable from the other home delivery position instruction marks M1 as described above.

On the other hand, if the read information does not correspond to the home-delivery position instruction mark M1 selected and instructed (step 180: NO), a warning is issued by an alarm (step 200). When the worker notices and inputs the correct information from the courier slip 21 of the parcel 25,
The process returns to step 180 and a YES determination is made.

After performing the processing of steps 170 to 200 on all the loads 25, if a switch (not shown) for instructing the end of loading / unloading is operated and it is determined that the loading / unloading is completed (step 210: YES), A display indicating that the home delivery has been completed is displayed on the display 7 (step 220).

As described above, according to the home delivery navigation system of this embodiment, on the navigation map NM displayed on the display 7 of the navigation device 60,
At least the position information of the delivery destination is displayed among the delivery information read from the home delivery slip 21 together with the current position of the own vehicle. Since the delivery destination can be successively indicated to the worker in this manner, even a inexperienced courier worker can find the vehicle position (current position display mark M2) and delivery destination position on the navigation map NM. By looking at the (home delivery position instruction mark M1) and delivering by being guided by it, it is possible to effectively prevent omission or forgotten delivery.

When the parcel 25 is unloaded from the delivery vehicle 100, if the read delivery information corresponds to the position information selected and designated, the navigation map NM.
Since the position information designated and selected above is erased, and a warning is issued if it does not correspond, it is possible to immediately find the wrong package 25 when it is unloaded, and the delivered package 25 The position information regarding the information about the package and the position information about the package to be delivered will not be confused, and it is more effective to prevent delivery mistakes and forgetting delivery.

Next, another embodiment will be described. In the above-described embodiment, the delivery information is input to the navigation device 60 by individually reading with the interrogator 70 when loading the parcel 25 into the delivery vehicle 100, but when the parcel 25 is sorted by destination at the delivery center. Alternatively, the shipping information collectively collected when the luggage 25 to be loaded in a certain delivery vehicle 100 is stocked may be stored in an IC card or a magnetic floppy disk and input to the navigation device 60 by using it. .

In this case, when loading the delivery vehicle 100, it is not necessary to read the documents one by one, and it is sufficient to simply load the luggage 25, so that the burden on the loading operator is reduced. In the above embodiment, only the delivery information is input to the navigation device 60, and the navigation map NM
The data related to the data used in the device itself are used, but the delivery information is combined with the navigation map NM and stored in advance in an information medium such as a CD, and the map data input device 2 of the navigation device 60 is used. You may make it input more.

In this case, it is sufficient to simply load the luggage 25 at the time of loading the delivery vehicle 100.
The burden on the loading operator is reduced, and the configuration on the navigation device 60 side can be simplified and the cost can be reduced. For example,
If the navigation device 60 itself has data on the navigation map NM, it may be necessary to have all the navigation maps NM in a region (for example, the whole country) where there is a possibility of delivery. This is because, if there is, it may be combined with the navigation map NM for only the delivery area in advance, and the data amount can be relatively small.

[0044]

As described above, according to the home delivery navigation system of the present invention, the delivery information read from the electronic tag along with the current position of the vehicle is displayed on the map displayed on the display unit of the navigation means. At least the location information of the delivery destination is displayed, so even an inexperienced courier worker can set the delivery route like an experienced operator by looking at the own vehicle position and the delivery destination position on the map. As a result, it is possible to effectively prevent missed deliveries and missed deliveries.
