Abstract

PURPOSE:To confirm the direction and distance of a starting point by directly connecting an azimuth detection sensor to a calculation mechanism and connecting a pedometer and an inclination correction sensor thereto through or not through a converter and performing operation by the calculation mechanism. CONSTITUTION:An azimuth detection sensor 1 is constituted by combining two earth magnetism sensors to detect the direction on a horizontal surface and informs the same to a calculation mechanism 2 having a microcomputer built therein. A pedometer 3 counts the number of steps and a converter (to which one step of an indivisual is inputted) 4 coverts the counted value to a distance to inform said distance to the calculation mechanism 2. An inclination correcting sensor 5 detects a plane step due to the inclination of a road to inform the same to the converter 4 and corrects the distance due to the information of the counter 3 to inform said distance to the calculation mechanism 2. The calculation mechanism 2 calculates an azimuth and a direct distance on the basis of these input data to display the azimuth and direct distance at each time on a display means 6. A switch is separately provided so as to display both values at a desired time. The converter 4 may be omitted to calculate the data to be obtained by the respective sensors by the calculation mechanism 2.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a remote location confirmation device for confirming the direction and distance of a starting point.

(Prior Art) Conventionally, a pedometer has been used as a measuring device for determining how far a person has walked from a starting point. Cars also use odometer needles. To check the direction, there is a magnetic compass needle.

(Problem to be solved by the invention) Conventionally used pedometers can check how many steps have been taken from the starting point, but in mountainous areas and other places with steep elevations, there is a difference in stride length, making it difficult to measure the distance. The error is large, and
It is not possible to check the direction and distance from the starting point on roads other than straight roads.

Also, with a magnetic direction indicator, you can tell the direction from your current location, but you cannot confirm which direction your departure point is.

This invention is useful when you get lost due to a forest fire, mountain climbing, hiking, orienteering, etc., or when an elderly person gets lost, so that you can confirm the direction and distance of your starting point. The purpose is to

(Means for solving the problem) The direction detection sensor is connected directly, the step counter and the tilt correction sensor are connected to a computer mechanism with or without a converter, and the direction and straight line distance from the starting point calculated by the computer mechanism are calculated. and connect them to a power source.

(Example) Embodiments of the invention will be described with reference to the drawings.

The direction detection sensor 1 detects the direction on the horizontal plane by combining two geomagnetic sensors, and continuously notifies the calculation mechanism 2 having a built-in microcomputer.

The direction detection sensor 1 is not limited to a geomagnetic sensor, and other known sensors that exhibit the above functions can be used.

A step counter 3 counts the number of steps, converts it into a distance using a converter 4, and reports the result to a calculation mechanism 2.

The inclination correction sensor 5 detects the plane step length due to the inclination of the road, and reports it to the converter 4, corrects the distance reported by the step counter 3, and reports it to the calculation mechanism 2.

The converter 4 may be omitted, and the step count counter 3 and the tilt correction sensor 5 directly report to the calculation mechanism 2, and the calculation mechanism 2 may perform the calculation.

The calculation mechanism 2 inputs data from the orientation sensor 1, step counter 3, and tilt correction sensor 5, calculates the orientation and direct distance, and displays the orientation and linear distance on a display means 6 such as a liquid crystal display board. This display may always display the current data, or a switch may be provided separately so that only the display means 6 can be displayed at a desired time.

The converter 4 allows the stride length of each individual to be input. If the converter 4 is omitted, the stride length is input to the calculation mechanism 2.

- Each means is wired to a power source such as a battery (omitted in the drawing), so that when the power is turned off, the data input from each means to the calculation mechanism 2 is cleared to zero.

(Functions and Effects) The direction detection sensor l detects the direction from the starting point and reports it to the calculation mechanism 2, the step counter 3 counts the number of steps, and the inclination correction sensor 5 detects the inclination of the road and converts it.
a4 or directly to the calculation mechanism 2, and the calculation mechanism 2 constantly corrects the direction, calculates the plane straight line distance, and reports it to the display means 6.0 The display means 6 displays the current direction and straight line distance. Display.

By making this remote location confirmation device small and carrying it with you, if you get lost deep in the mountains, you can easily check in which direction and how far away you are from your starting point, making it easy to return to your starting point. It will be more effective if you carry a map with you.Also, if an elderly person carries a map, if they get lost or fall down on the way, a police officer or a passerby can see the sign and help them find their home. You can know the direction and distance of

Note that it would be convenient if this device was equipped with a transmitting mechanism so that it could send notifications to a television set in the home or the like.
