Abstract

(57) [Summary] [Purpose] When a target point is approached, by notifying the corresponding point on the map corresponding to the target point, the fact that the target point is approached is notified to call attention. [Structure] Low-power transmitters 2A, 2B, and 2C for transmitting identification signals unique to a target location are installed at target points A, B, and C, respectively. A receiver 3 that operates in the radio wave area is installed on the map 1. A memory circuit 4 for accommodating an identification signal to which a target existing in the map 1 belongs and a logic circuit 5 for collating the received identification signal with the stored identification signal are provided. When the identification signals match, the notification unit 6 displayed on the map 1 is set to the target points A, B,
They are provided at corresponding points 1A, 1B and 1C on the map corresponding to C, respectively.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for reporting a target point on a map corresponding to the target point when the target point is approached.

[0002]

[Prior art]

 There is no device that notifies the target point on the map corresponding to the target point when the target point is approached on the conventional map.

[0003]

[Problems to be solved by the device]

 Everyone is experiencing that it is hard to grasp a sense of distance when they go to a target point while looking at a map. In the conventional map, even if the target point is approached, no means for notifying that the target point is approached is taken.Therefore, when the target point cannot be reached while approaching the target point, or in the case of a car, etc., You may pass the target point without knowing it, and you may feel a great deal of fatigue because of wasted effort such as turning back.

In view of this, the present invention provides a map that can alert the user when he or she approaches a target point by notifying the corresponding point on the map that corresponds to the target point. It is intended to provide a corresponding point notification device.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention installs low-power transmitters that emit identification signals unique to the target location at the target points, respectively, and installs a receiver operating in the radio wave area on the map. A memory circuit that stores the identification signal to which the target existing on the map belongs, and a logic circuit that collates the received identification signal with the stored identification signal are provided, and the notification unit that displays on the map when the identification signal matches is the target point. It is characterized in that it is provided at each corresponding point on the map corresponding to.

[0006]

[Action]

 The operation of the present invention will be described. When the target point is approached, the receiver installed on the map receives the identification signal unique to the target point transmitted by the transmitter installed at the target point. Next, the logic circuit sequentially checks whether the received identification signal is the same as the identification signal of the memory circuit stored in the map, and when both identification signals match, the corresponding point on the map corresponding to the target point is identified. The notification part is displayed by blinking or the like.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the device of the present invention. In the figure, A, B, C ... are target points, 1 is a map, 1A is a target point on the map of the target point A, 1B is a target point on the map of the target point B, 1C is a target point C. It is the corresponding point on the map.

Reference numeral 2A is a transmitter installed at the target point A, 2B is a transmitter installed at the target point B, and 2C is a transmitter installed at the target point C. The transmitters 2A, 2B and 2C are both low power type. The transmitters 2A, 2B, 2C ... Emit identification signals unique to the target point.

Reference numeral 3 denotes a receiver installed on the map 1, which operates within the area of the radio wave transmitted by the transmitter. Reference numeral 4 is a memory circuit which communicates with the receiver 3 and stores an identification signal to which the target point existing on the map 1 belongs. 5 is a logic circuit which communicates with the receiver 3 and the memory circuit 4 and collates the received identification signal with the memory identification signal, and 6 when the received identification signal matches the identification signal of the memory circuit 4 stored in the map , A notification unit that displays the corresponding point on the map by blinking light or the like.

[0010]

[Effect of device]

 According to the present invention, when the target point is approached, the display appears on the corresponding point on the map, so that it can be recognized that the current target point is approached and the user can be alerted. By combining the display with sound, the notification function can be enhanced, and by changing the display according to the electric field strength, the degree of proximity to the target can be expressed. Further, in the present invention, since the target is classified by the identification signal, the radio wave need only have a single frequency, and since the identification signal is collated, highly accurate recognition is possible. Moreover, since the frequency is fixed, the production cost of the transmitter and the receiver can be reduced. Furthermore, if the identification signal is grouped and set according to the genre such as a coffee shop, a stop, a toilet, etc., the present invention can provide guidance by selecting the genre, which is very convenient and has high practical value.
