Abstract

PROBLEM TO BE SOLVED: To enable a direction indicator to be portable outdoors, to facilitate the operation, and to indicate the direction of the destination and the distance. SOLUTION: A direction indicator 1 is constituted of an antenna 2, a destination display unit 5 for indicating the latitude and the longitude of the destination, a switch for switching the latitude and the longitude, an advancing/ retreating switch 7 for advancing or retreating the latitude and the longitude, a distance display unit 6 for displaying the distance to the destination, and a direction display unit 8 for displaying the direction to the destination by an arrow 9, and an outside connection part 3 through which the position of the destination is to be input from the outside. The direction indicator receives the electric wave from an artificial satellite, amplifies it, converts it into a digital signal, and calculates the present position. Next, it discriminates whether the first set destination is remain set also in the present. When the destination is changed, the destination is changed to the now set destination, and the direction and the distance in relation to the destination are calculated and displayed.

Description

Detailed Description of the Invention

[0001]

[Industrial applications]

[0002] The present invention relates to industrial activities, for example, which require constant knowledge of the direction and distance to a destination during outdoor activities.

[Prior art]

Conventionally, the method of knowing one's current location outdoors is as follows.
A method was used to estimate the direction to the destination and the distance to the destination from nearby landmarks using a magnet and a map.

However, this method cannot be applied to a strange land. Although there are control systems for navigation and systems using gyros, they are expensive and require large-scale equipment.

Further, there is an automobile navigation system using artificial satellites, but the device is large and expensive, and is not suitable for portable use.

[0006]

[Problems to be Solved by the Invention]

[0007] Conventionally, the car navigation system has a drawback that it is not suitable for the purpose of being easily carried outdoors because it is a device for fixing inside the car by using the power supply of the car. Another drawback is that the system is expensive because it is equipped with electronic maps.

The present invention was devised under the circumstances described above, and it is an object of the present invention to provide a device which can be carried outdoors, is extremely easy to operate, and always indicates the direction of a destination. It is an issue.

[0009]

[Means for Solving the Problems]

To achieve the above object, the present invention provides
The following technical measures are taken. In other words, without using conventional hardware, only a simple input of the destination, a display mechanism that always indicates the direction, and a mechanism that always displays the distance to the destination are miniaturized and portable. And means for doing so.

[0011]

[Action]

The direction indicator receives radio waves from an artificial satellite and amplifies them. Since the signal of the radio wave is an analog signal,
Convert to digital signal. The current position of the turn signal is calculated from the digital signal.

Next, it is identified whether or not the initially set destination is still set at the same time.
If the destination has been changed, change to the newly set destination.

The direction indicating device calculates the direction and the distance to the destination with respect to the preset destination or the newly set destination. Display the last calculated direction and distance.

[0015]

【Example】

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of the device of the present invention. The direction indicator 1 includes an antenna 2, a destination display section 5 for displaying the latitude and longitude of a destination, a switch 4 for separating the latitude and longitude, and a step / back switch 7 for stepping or retracting the latitude and longitude. A distance display unit 6 for displaying the distance to the destination, a direction display unit 8 for displaying the direction to the destination with an arrow 9, and an external connection unit 3 for inputting the position of the destination from the outside. Has been done.

Next, the operation of the apparatus of the present invention will be described with reference to the flowchart.

FIG. 3 is a functional flowchart showing the processing steps of the turn signal indicating device according to the embodiment of the present invention.

The direction indicator is a GPS (Groval Posotio).
A radio wave is received from an artificial satellite such as the ning system) and amplified (step 101). Since the radio wave signal is an analog signal, it is converted to a digital signal (step 10).
2). The current position of the turn signal is calculated from the digital signal (step 103).

Next, it is identified whether or not the initially set destination is still set at the same time (step 104). If the destination has been changed, the destination is changed to the newly set destination (step 105).

The direction indicator calculates the direction and distance to the destination with respect to the preset destination or the newly set destination (step 106).
Display the last calculated direction and distance (step 10)
7).

When the above operation is completed, step 101
Repeat the bounce operation.

[0023]

【The invention's effect】

According to the present invention, by carrying the turn indicator, it is possible to accurately know the preset direction of the destination and the distance to the destination. Further, the direction indicator according to the present invention can be miniaturized by using semiconductor technology, and can be incorporated in a watch or the like to realize a low-priced portable direction indicator function, which can prevent accidents, seek lost children, and dementia Many applications such as confirmation of whereabouts of old people and recreation such as stamp rally are possible, which has the effect of being useful to society.
