Description

  The present invention relates to an electronic timepiece and a program.

  Conventionally, there is an altimeter that displays the altitude (altitude) of the current location (see, for example, Patent Documents 1 and 2), and when a user climbs a mountain, based on the altitude displayed on the altimeter, “What percentage of achievement rate” relative to the altitude was simply calculated in my head by “altitude at the current location ÷ elevation at the summit = achievement rate”. In addition, there is a watch that confirms a passing point using position information such as GPS (Global Positioning System) (see, for example, Patent Document 3).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an external configuration of an electronic timepiece 100 according to the present embodiment. The electronic timepiece 100 is an electronic timepiece with an altitude measurement function. As shown in the figure, the electronic timepiece 100 includes a plurality (six in this embodiment) of key input means 104A to 104F and a display unit 105.

  Key input means 104A to 104F (operation units) accept operation inputs. Note that the operation unit that receives an operation input may be composed of a plurality of key input means 104 or a single key input means 104. The display unit 105 is a liquid crystal display, a segment display, or the like, and displays information.

  FIG. 2 is a block diagram illustrating a configuration of the electronic timepiece 100 according to the present embodiment. In the illustrated example, the electronic timepiece 100 includes a CPU (Central Processing Unit) 101 (display control unit, acquisition unit), an oscillation circuit 102, a frequency dividing circuit 103, a key input unit 104, a display unit 105, a battery, 106, an atmospheric pressure measurement unit 107, an altitude measurement unit 108, a RAM (Random Access Memory, random access memory) 110 (storage unit), and a ROM (Read Only Memory, read only memory) 111.

  The CPU 101 controls each unit included in the electronic timepiece 100. Further, the CPU 101 compares the altitude measured by the altitude measuring unit 108 with the altitude information stored in the RAM 110, and acquires current position information regarding the current position. The current position information is the climbing achievement rate. This achievement rate is a value based on the distance from the start point to the current position and the distance from the start point to the goal point. The CPU 101 displays the acquired current position information on the display unit 105.

  In addition, the CPU 101 measures the current time based on the measurement signal input from the frequency dividing circuit 103 and displays it on the display unit 105. In addition, the CPU 101 displays the altitude input from the altitude measuring unit 108 on the display unit 105.

  The oscillation circuit 102 generates an oscillation signal having a predetermined frequency (for example, 32768 Hz) and outputs the oscillation signal to the frequency dividing circuit 103. The frequency dividing circuit 103 divides the frequency of the oscillation signal input from the oscillation circuit 102 to generate a measurement signal serving as a measurement reference, and outputs the generated measurement signal to the CPU 101. Key input means 104 (104A-F) accepts an operation input. The battery 106 supplies power for operation to each unit included in the electronic timepiece 100.

  The atmospheric pressure measurement unit 107 is, for example, an atmospheric pressure sensor, measures atmospheric pressure, and outputs the measured atmospheric pressure to the altitude measurement unit 108. The altitude measurement unit 108 measures the altitude based on the atmospheric pressure input from the atmospheric pressure measurement unit 107 and outputs the measured altitude to the CPU 101. The atmospheric pressure measurement unit 107 and the altitude measurement unit 108 constitute an altimeter that measures altitude.

  The RAM 110 stores data used by each unit of the electronic timepiece 100. For example, the RAM 110 stores an altitude table indicating altitude information regarding altitude at each of a plurality of registered points on the mountain climbing route. The ROM 111 stores an operation program executed by the CPU 101 in advance. This operation program is read when the CPU 101 is activated.

  Next, the altitude table stored in the RAM 110 will be described. FIG. 3 is a schematic diagram illustrating an example of the mountain climbing route R registered in the altitude table stored in the RAM 110 according to the present embodiment. The altitude table stores altitude information of each of the plurality of milestones (1) to (6) on the mountain climbing route R in order from the start point to the goal point. A milestone is a registration point, for example, an inflection point of a gradient. In this example, the altitude table is (1) A terminal, (2) B campground, (3) C hut, (4) D villa, (5) E point, (6) Mt. Store altitude information. (1) Terminal A is the starting point, and (6) Mt. F is the goal point. Moreover, each point of (2)-(5) is an inflection point of the gradient in the mountain climbing route R.

  FIG. 4 is a schematic diagram illustrating a data configuration and a data example of the altitude table stored in the RAM 110 according to the present embodiment. As shown in the drawing, the altitude table has items of milestone, altitude, achievement rate (1), distance, achievement rate (2), and average slope.

  A milestone is a registration point on a mountain climbing route. The altitude is the altitude (in meters) of the milestone. Achievement rate (1) is the altitude conversion achievement rate (unit: percent), calculated by the formula "(milestone elevation-starting point elevation) / (goal point elevation-starting point elevation)" Value.

  The distance is the distance (in kilometers) from the starting point to the milestone. The achievement rate (2) is the distance conversion achievement rate (unit: percent), which is a value calculated by the formula “(distance from start point to milestone) / (distance from start point to goal point)”. is there. The average slope is an average value of the slope from the previous milestone to the current milestone.

  In the example shown in this figure, (1) the elevation of terminal A is 2450 m, the achievement rate (1) is 0%, the distance is 0 km, the achievement rate (2) is 0%, and the average slope Is-. (2) The altitude of the B campsite is 2260m, the achievement rate (1) is -35%, the distance is 2.0km, the achievement rate (2) is 30%, and the average slope is -5 degrees. (3) The altitude of the C hut is 2760 m, the achievement rate (1) is 56%, the distance is 3.5 km, the achievement rate (2) is 50%, and the average slope is 18 Degree. (4) The elevation of D Zhuang is 2475m, the achievement rate (1) is 5%, the distance is 5.4km, the achievement rate (2) is 75%, and the average slope is -8. Degree. In addition, (5) the elevation of the E point is 2813 m, the achievement rate (1) is 66%, the distance is 6.5 km, the achievement rate (2) is 90%, and the average slope is 17 degrees. It is. (6) The altitude of Mount F is 2999 m, the achievement rate (1) is 100%, the distance is 7.1 km, the achievement rate (2) is 100%, and the average slope is 17 degrees. It is.

  As described above, in an uneven mountain climbing route rich in ups and downs, a phenomenon occurs in which the achievement rate (1) in terms of elevation increases or decreases. On the other hand, the achievement rate (2) in terms of distance increases even with a rough mountain climbing route rich in undulations according to the distance traveled.

  Next, a method in which the CPU 101 displays the achievement rate on the display unit 105 will be described. First, the CPU 101 acquires the measured altitude measured by the altitude measuring unit 108. Subsequently, the CPU 101 compares the acquired measured altitude with the altitude of each milestone stored in the altitude table, and determines the milestone that has passed. Specifically, the CPU 101 first compares the measured altitude and the altitude in order from the start point, and determines that the milestone has been passed if the difference between the measured altitude and the altitude is equal to or less than a predetermined value. Thereafter, the CPU 101 compares the measured altitude with the altitude of the next milestone after the passed milestone to determine whether or not the next milestone has been passed. In this manner, the CPU 101 determines whether or not each milestone has been passed by sequentially comparing the altitude of the milestones stored in the altitude table with the measured altitude.

  When determining that the milestone has passed, the CPU 101 reads out the achievement rate (2) corresponding to the passed milestone from the altitude table. And CPU101 displays the read achievement rate (2) on the display part 105 as a climbing achievement rate (achievement rate with respect to a climbing plan).

  Thus, in this embodiment, since the electronic timepiece 100 displays the distance conversion achievement rate (2), the electronic timepiece 100 displays the achievement rate with higher accuracy than the altitude conversion achievement rate (1) in the prior art. can do. In addition, the electronic timepiece 100 determines the current position (passed milestone) based on the altitude measured by the altitude measuring unit 108 and the altitude table and determines the achievement rate, so that new position information is acquired. It is not necessary to mount the sensor.

  Next, an achievement rate display process in which the electronic timepiece 100 according to the present embodiment displays an achievement rate will be described. FIG. 5 is a flowchart showing a processing procedure of the achievement rate display process executed by the electronic timepiece 100 according to the present embodiment. When the key input means 104 receives an operation input indicating the start of mountain climbing, the electronic timepiece 100 repeatedly executes the achievement rate display process shown in the drawing.

(Step S101) The CPU 101 acquires the measured altitude measured by the altitude measuring unit 108. Thereafter, the process proceeds to step S102.
(Step S102) The CPU 101 compares the acquired measured altitude with the altitude of the earliest milestone among the unpassed milestones. Thereafter, the process proceeds to step S103.

  (Step S103) The CPU 101 determines the milestone that has passed. Specifically, when the difference between the measured altitude compared in step S102 and the altitude of the milestone is equal to or less than a predetermined value, the CPU 101 determines that the milestone has been passed. On the other hand, if the difference between the measured altitude and the altitude of the milestone is greater than a predetermined value, the CPU 101 determines that the milestone has not been passed. Thereafter, the process proceeds to step S104.

(Step S104) The CPU 101 determines the achievement rate of mountain climbing. Specifically, the CPU 101 reads out the achievement rate (2) corresponding to the last passed milestone from the altitude table, and sets the read achievement rate (2) as the climbing achievement rate. Thereafter, the process proceeds to step S105.
(Step S <b> 105) The CPU 101 displays the climbing achievement rate determined in step S <b> 104 on the display unit 105. Thereafter, the process ends.

  As described above, in the present embodiment, the CPU 101 determines the milestone that has passed by comparing the altitude of each milestone stored in advance in the altitude table with the measured altitude. Then, the CPU 101 reads the distance conversion achievement rate (2) corresponding to the passed milestone from the altitude table, and displays the read achievement rate (2) on the display unit 105. That is, since the electronic timepiece 100 displays not the altitude conversion achievement rate but the distance conversion achievement rate, it avoids “a phenomenon in which the climbing achievement rate rises or falls” that occurs on an uneven mountain climbing route that is undulating. be able to. Therefore, the electronic timepiece 100 can display an accurate climbing achievement rate even on a rough mountain climbing route. Furthermore, the electronic timepiece 100 can grasp an accurate climbing achievement rate only by using an altimeter without using a position information sensor such as GPS. Therefore, an electronic timepiece 100 equipped with an altimeter that is small, lightweight, and power-saving can be realized without mounting a position information sensor.

  Note that all or some of the functions of each unit included in the electronic timepiece 100 in the embodiment described above are recorded on a computer-readable recording medium and a program for realizing these functions. You may implement | achieve by making a computer system read a program and executing it. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program that holds a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
