DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to the drawings. The navigation device of this embodiment is a device that reads map information and peripheral information from a storage medium having a small storage capacity.
[0009]
FIG. 1 is a block diagram showing a configuration of a main part of the embodiment. (1) is a control circuit which controls each part based on the program written in ROM (2). (3) is a RAM which stores information necessary for the operation of the control circuit (1). (4) is a GPS (Global Positioning System) positioning means that receives radio waves from GPS satellites, measures the current position, and outputs the measurement data to the control circuit (1). (5) is a DVD playback apparatus, which reads map information from a DVD in which map information of a plurality of scales is written. (6) is a transmission / reception circuit for transmitting / receiving data to / from the station. (7) is an input unit operated by the user. (8) is a liquid crystal display unit that displays map information, peripheral information, and the current position based on the control of the control circuit (1).
[0010]
With the above configuration, the navigation device downloads service information, advertisements, and other information from the station via the transmission / reception circuit (6) and stores them in the RAM (3). Each guide has search data illustrated in FIG. 2 in addition to the guide data. The guidance data is name, position, and content data (for example, a menu for a restaurant and a gasoline price for a gas station).
[0011]
The search data illustrated in FIG. 2 will be described. There are many guides for service information, advertisements, etc., and receiving all of them is an obstacle in terms of communication time, communication cost, display capability, and search. Therefore, according to the present invention, before downloading the content data, only the content data that meets the conditions set by the user is received. An example of setting conditions for this is the table of FIG.
[0012]
As the type condition A of group A, No. 0 is “None”, No. 1 is “Sports”, No. 2 is “Leisure”, No. 3 is “Sale”, No. 4 is “Pachinko”, No. 5 is “Event” is there. As B group type condition B, No. 0 is “None”, No. 1 is “Market”, No. 2 is “Gas station”, No. 3 is “Tourist”, and No. 4 is “Dining place”. As the position condition of the C group, No. 0 is “None”, No. 1 is “Prefecture”, No. 2 is “Current Area”, and No. 3 is “Destination Area”. As the date and time conditions for the D group, No. 0 is “none”, No. 1 is “valid time”, No. 2 is “effective date”, and No. 3 is “invalid day of the week”.
[0013]
In all groups, the user can select a plurality from among the first and subsequent users. If none of them are selected, the number 0 “None” is automatically selected, and all the contents data of the group are downloaded. The logical relationship of the groups A to B is (group A or group B) and group C and group D.
[0014]
Before downloading the content data from the song, the search data to be received is, for example, as shown in FIG. 2, the information name is Kappo XX, the type condition B is the restaurant, and the position is 135 degrees 12 seconds east 35 degrees 24 seconds north latitude When the opening hours are from 11:00 to 20:00 and the holiday is Wednesday, the search data is “N; Kappo XX / B4 / C; 13512,03524 / D1; 1100,2000 / D3; 3”. In this way, a semicolon “;” is inserted between the item number of each condition and necessary data, and a slash “/” is inserted between each item.
[0015]
Next, the operation of the present invention will be described. FIG. 3 is a flowchart showing the operation of the control circuit (1), and FIG. 4 is a flowchart showing the detailed operation of step S7 in FIG. When the operation of the setting condition shown in FIG. 2 is performed by the input unit (7), the control circuit (1) stores the operated condition in the RAM (3) (S1, S2).
[0016]
When receiving the reception instruction (Y in S3), the control circuit (1) receives the search data from the station (S4). Here, various cases correspond to the reception instruction. For example, when receiving is started when the input unit (7) is operated (for example, when preparing for departure), every time a predetermined distance is moved or when a predetermined time elapses, an activation signal from the station (for example, An advertisement notification signal transmitted from a station when approaching a restaurant or combination is considered.
[0017]
Based on the received one or more guidance search data, one that matches the classification condition A or the classification condition B is selected (S5). Thereby, the guidance is narrowed down to the set type. Next, the one that matches the position condition is selected (S6). As a result, the guidance is narrowed down to the set position (area). Next, the one that matches the date and time condition is selected (S7).
[0018]
The detailed operation of step S7 will be described with reference to FIG. If guidance to be processed remains after narrowing down to step S6 (S11), the control circuit (1) selects the first guidance as a processing target (S12). The arrival date and time of the selected guide is predicted and calculated (S13). Prediction calculation is calculated by simulating the shortest distance from the current position to the guidance position. The simulated driving is calculated in consideration of the road type, the number of lanes, the number of right and left turns, the number of traffic lights / railway breakers, road traffic information, and the like.
[0019]
If the arrival date and time when the date and time setting conditions are predicted is not in time, the guidance is excluded from the selection of content data download (S15). If there is room (in the case of reaching 30 minutes before) (Y in S16), the process proceeds to step S18. When there is no room (N in S16), the control circuit (1) attaches a flag with a timer to the guidance. When there is a flag with a timer, the remaining time is displayed when displaying the guidance. For example, the time until the bank closes is displayed. A process of selecting those that meet the date and time conditions is performed for all the guides (S18, S19, S13).
[0020]
Returning to FIG. 3, after the processing of step S7, that is, only the guidance data of guidance narrowed down by the conditions set by the user is downloaded and stored in the RAM (3) (S8). The guidance data stored in the RAM (3) is displayed as necessary (for example, during travel, when setting a route, when searching for services and advertisements). In addition, the remaining time is displayed for the guidance with a timer.
[0021]
【The invention's effect】
With the widespread use of navigation devices, mobile phone devices equipped with GPS, PDAs, etc., demand for service information by communication increases, and advertisements increase. From such a large amount of guidance, the guidance desired by the user can be easily narrowed down, which is effective in terms of communication time, communication cost, display size, and search.
