Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a system for displaying various information necessary for the operation of a moving vehicle such as a car or a train on an image display device installed inside the vehicle. be.

[Conventional technology]

Navigation systems for determining the current location of aircraft and ships have been known for a long time.
No. 48008 discloses a device for recording a wake as a soft image. Recently, navigation systems have been developed for automobiles, and some of the systems have been put into practical use. These systems set the destination of the vehicle in advance, and display the current location of the vehicle along with driving information such as the distance and direction to the destination, which changes from time to time, as well as maps of the surrounding area, while the vehicle is in operation. It's meant to help you drive.

[Problem that the invention seeks to solve]

However, in conventional navigation systems for automobiles, operational information such as maps is retrieved from a storage medium in the vehicle, such as film or IC memory, and displayed, which has the inconvenience of not displaying information in real time. For example, if you try to store a map that cannot display road congestion, weather, etc., or can cover a wide area, the amount of storage media will be large and expensive. When there is a change in the operation information such as a map, each operator has to replace the changed information each time, which is troublesome.

The present invention aims to solve the above-mentioned inconveniences.
The purpose is to provide a method of displaying operation information that can display information in real time and that eliminates the need for operators of each transportation vehicle to worry about changes even if there is an alteration to a map or the like.

[Means for solving problems]

The means for solving the above problems are described in the first embodiment corresponding to the embodiment.
The procedure will be explained with reference to the figure.

A signal 3 requesting operation information is transmitted by a mobile transceiver 2 mounted on a moving object such as an automobile 1. When the transceiver 6 of the base station 5 receives the request signal 3, it transmits a signal 7 of operation information corresponding to the request. When the mobile transmitter/receiver at2 receives the operation information signal 7, the operation information signal 7 is stored in the memory 8. The current position signal 11 of the vehicle detected by the current position detection device 10 is also stored in the memory 8.

The contents stored in the memory 8 are then displayed on the image display device 12.

[Effect]

If the base station 5 inputs real-time operation information such as the latest updated maps and road congestion conditions, operators in the transmission territory of that base station can obtain that operation information at any time. . Then, the current position image of the moving vehicle will be displayed on the same screen as the real-time operation information image.

〔Example〕

FIG. 1 is an example of a block circuit for implementing the operation information display method to which the present invention is applied. As shown in the figure, a vehicle l, which is a moving body, has a mobile transmitting/receiving system 4I! 2, display memory 8, current position detection device lO1 image display device 12,
Transmitting/receiving antenna 13, map memory 15, first extractor 16. Range determiner 17, passing position memory 18, second extractor 19, destination memory 20, symbol generator 22. Distance calculator 23, character/character generator 24, and operation keys 251
・252 ・253 Keyboard 25 with Φ・misery
(See Figure 4) is installed. The base station 5 is provided with a transceiver 6, a transceiver antenna 27, a map memory 28, and an input device 29.

The current position detecting device IO is, as shown in FIG.
Global Positioning
stem ) It consists of a receiver 30 , a receiving antenna 31 , a magnetic compass 32 , an odometer 33 , an estimated position calculator 35 , and a data switch 36 .

The operation of the circuit will be explained below.

In the base station 5, a map of the necessary range is assigned a code to each leaf and is inputted into the map memory 28 from the input device M29 and stored therein.The contents of the map memory 28 are stored in the map memory 28 when the map is modified, etc. 29, subject to change at any time. In addition, accompanying real-time information such as road conditions and weather is attached to each map.On the car side, the operator or driver operates the key 251 on the keyboard 25 to input the equinox code for one or more maps. A command is given to the mobile transceiver 2. The mobile transceiver a2 transmits the request signal 3 through the antenna 13. The base station 5 receives this request signal 3 through the antenna 27 at a transmitter/receiver 4116.

The memory 28 is then searched and the map corresponding to the request signal 3 is retrieved together with the accompanying information.

The transceiver 6 then transmits an information signal 7 of the map and accompanying information through the antenna 27. On the vehicle l side, this information signal 7 is received by the transmitter/receiver 412 and stored in the map memory 15.
When the current position signal 11 (described later) is input, the map of the position where the car is traveling is stored in the map memory 1.
5, an amount corresponding to the display range of the display memory 8 is extracted, enlarged, and written into the display memory 8.

The current position detection device 10 measures and detects the current position of the automobile I and outputs a current position signal 11. As shown in Fig. 2, the GPS receiver 30 receives radio waves emitted from multiple satellites through the antenna 31 and outputs the current position signal 11. Considering that the GPS receiver 30 will not be able to receive enough radio waves for positioning, the system is designed to compensate for this.0 When the GPS receiver 30 can receive enough radio waves under normal conditions, the data switch 36 switches to the second Connected in the illustrated state, the current position signal 11 detected by the GPS receiver 30 is output. When the received radio waves become weak, the GPS receiver 30 issues an alarm signal 38, and the signal 36 changes the connection of the data switch 36 to the estimated position calculator 35 side. When the alarm signal 38 is input, the estimated position calculator 35 outputs the alarm signal 3.
The estimated position is calculated by adding the data of the magnetic compass 32 and the odometer 33 to the current position signal 11 just before 8 is output, and the current position signal 1t-z is output.This current position signal 11-2 is sent to the data switch. 36 to compensate for the current position signal 11 that cannot be output by the GPS receiver 30. Furthermore, GPS
The receiver 30 may not be provided, and the current position may be detected using only the magnetic compass 32 and the distance meter 33 from the time the automobile 1 starts traveling, and the current position signal may be output. The configuration for positioning and detecting the current position and the configuration for positioning and detecting the current position of the automobile 1 using the magnetic compass 32 and the distance meter 33 are well known, and detailed explanations thereof will be omitted.

In FIG. 1, the current position signal 11 output from the current position detection device 10 is first extracted from the passing positions stored in the passing position memory 18, which is stored as passing positions at appropriate position intervals. The second extractor 19 extracts the travel locus within the map display range set by the device 16 and writes it into the display memory 8.
52 to input the location of the destination. For example, the destination is encoded as latitude and longitude, or address/lot number.

The symbol generator 22, which can correspond to the code on the map, generates a symbol that indicates the destination read from the destination memory 20 within the map display range set by the first extractor 16. , the distance calculator 23 calculates the distance from the current position of the vehicle 1 to the destination based on the current position signal 11 and the destination. The result of the calculation is converted into characters by a character generator 24 and written into the display memory 8. When the current position signal 11 of the vehicle 1 is near the edge of the map, the range determiner 17 determines whether or not the next map (the map on the traveling side of the vehicle 1) exists in the map memory 15. If there is not one, the mobile transceiver 2 is instructed to find the necessary map.

The mobile transceiver 2 then sends the request signal 3 again.
In response to a request, the base station 5 issues an information signal 7 in the same manner as described above.

The four pieces of information written in the display memory 8 as described above, namely the map extracted by the first extractor 16 and the second extractor 1
The travel trajectory extracted in step 9, the destination symbol generated by the symbol generator 22, and the distance number generated by the character generator 24 are displayed on the image display device 12 in a superimposed manner. FIG. 3 shows a map displayed on the image display device 12 along with a road congestion situation 42 and a destination 4o.
The image display device 1 is an example of displaying the current position of a car, its travel trajectory 41, and the distance to the destination 43.
Various display devices such as a CRT display, a plasma display, an LED display, and a liquid crystal display can be used for the display 2. FIG. 4 shows an example in which a CRT display is mounted in an automobile 1 as the image display device 12. The operator can operate the keys 251, 252, and 253 as described above using the keyboard 25 shown in the figure.

Note that the embodiment shown in FIG. 1 can be implemented even if the map memory 15 and the first extractor 16 are omitted. In that case, an enlarged map is directly requested from the base station 5 by operating the operation key 251.

〔Effect of the invention〕

As explained above, according to the operation information display method of the present invention, each vehicle does not need to carry a large amount of maps on a storage medium as in the past. By simply inputting real-time operation information such as the latest modified maps and road congestion conditions into the base station, operators of each transportation company can obtain the latest operation information without having to modify the information. I can do it. The operating status of the operating vehicle will be displayed on the same screen as the real-time operating information image, making it extremely convenient.
