Abstract
A warning notification device includes a sensor, a notification unit, and a processor. The processor is configured to calculate a water depth from an output of the sensor every predetermined time and to calculate a surfacing amount from a change in the calculated water depth every predetermined time. When a long-term surfacing speed condition, which is to be determined on the basis of the surfacing amounts of a first number, is satisfied or when a short-term surfacing speed condition, which is to be determined on the basis of the recent surfacing amounts of a second number smaller than the first number, is satisfied, the processor enables the notification unit to issue a warning of a surfacing operation.
Claims20
A warning notification device comprising:
- a sensor;
- a notification unit;
- and
- a processor,
- wherein the processor is configured to calculate a water depth from an output of the sensor every predetermined time and to calculate a surfacing amount from a change in the calculated water depth every predetermined time, and
- wherein when a long-term surfacing speed condition, which is to be determined on the basis of the surfacing amounts of a first number, is satisfied or when a short-term surfacing speed condition, which is to be determined on the basis of the recent surfacing amounts of a second number smaller than the first number, is satisfied, the processor enables the notification unit to issue a warning of a surfacing operation.
A warning method of a warning notification device comprising a sensor and notification unit, the warning method comprising:
- calculating a water depth from an output of the sensor every predetermined time;
- calculating a surfacing amount from a change in the calculated water depth every predetermined time;
- and
- enabling the notification unit to issue a warning of a surfacing operation when a long-term surfacing speed condition, which is to be determined on the basis of the surfacing amounts of a first number, is satisfied or when a short-term surfacing speed condition, which is to be determined on the basis of the recent surfacing amounts of a second number smaller than the first number, is satisfied.
A non-transitory recording medium having a program recorded therein, which can be read by a processor of a warning notification device comprising a sensor, a notification unit and the processor, the recording medium having a program configured to enable the processor to execute:
- a command of calculating a water depth from an output of the sensor every predetermined time;
- a command of calculating a surfacing amount from a change in the calculated water depth every predetermined time;
- and
- a command of enabling the notification unit to issue a warning of a surfacing operation when a long-term surfacing speed condition, which is to be determined on the basis of the surfacing amounts of a first number, is satisfied or when a short-term surfacing speed condition, which is to be determined on the basis of the recent surfacing amounts of a second number smaller than the first number, is satisfied.
