Altitude information acquiring device and altitude information acquiring system
First Claim
1. An altitude information acquiring device comprising:
- a measuring unit which periodically measures atmospheric pressure;
a wireless communication unit which performs near field communication with an external device;
an altitude information acquiring unit which acquires altitude information from an external positioning device through the wireless communication unit;
an inversion detecting unit which detects a reversal of a changing direction, which is a direction in which the atmospheric pressure periodically measured by the measuring unit is changing;
an altitude calculating unit which converts atmospheric pressure values measured by the measuring unit into altitude values based on a predetermined table;
a communication control unit which sets a timing to acquire the altitude information through the wireless communication unit to a timing at which, after the reversal of the changing direction, an altitude change in the changing direction after the reversal is a preset altitude difference or more; and
an integrated altitude change acquiring unit which acquires a rise altitude integrated value obtained by integrating an amount of altitude change in a rising direction and a fall altitude integrated value obtained by integrating an amount of altitude change in a falling direction, based on the acquired altitude information.

Abstract
An altitude information acquiring device includes a measuring unit which measures atmospheric pressure; a wireless communication unit which performs near field communication with an external device; and an altitude information acquiring unit which acquires altitude information from an external positioning device through the wireless communication unit. An inversion detecting unit detects an inversion of a changing direction of the atmospheric pressure periodically measured by the measuring unit, and a communication control unit controls a timing to acquire the altitude information through the wireless communication unit at a set timing, based on the inversion detected by the inversion detecting unit. An integrated altitude change acquiring unit acquires a rise altitude integrated value obtained by integrating an amount of altitude change in a rising direction and a fall altitude integrated value obtained by integrating an amount of altitude change in a falling direction, based on the acquired altitude information.
