Abstract

An object of the present invention is to improve processing using a detection result of an atmospheric pressure sensor. In one aspect, a portable device includes an atmospheric pressure sensor that measures a value of atmospheric pressure, a touch screen, and a controller that estimates that the device itself has been immersed in water when the atmospheric pressure value satisfies a condition. Based on the detection result of the touch screen, the controller estimates whether the own device immersed in the water has come out of the water. Since the portable device uses the touch screen only when estimating whether or not the device has come out of the water, it is possible to determine whether or not the device has landed and whether or not the device has been watered while suppressing power consumption.

As shown in FIG. 2, the value of the atmospheric pressure measured by the atmospheric pressure sensor 17 shows a rapid increase of 10 hectopascals or more in about several seconds when the aircraft is immersed in water. For example, the controller 10 can determine whether the own device has been immersed in water by predefining a change in air pressure (inclination) per unit time when the own device is immersed in water. That is, the controller 10 can estimate that the own device has landed by comparing the change in the atmospheric pressure defined in advance with the change in the atmospheric pressure calculated from the value of the atmospheric pressure measured by the atmospheric pressure sensor 17.

On the other hand, as shown in FIG. 4, when the aircraft is out of the water, that is, when the aircraft is in the air after being removed, the change in the capacitance measured by the touch screen 2B is a certain negative value. The distribution becomes uniform in the vicinity. As shown in FIG. 5, when the touch screen 2 </ b> B is touched with a finger, the capacitance measured by the touch screen 2 </ b> B does not have a uniform distribution, unlike the examples shown in FIGS. 3 and 4.

  The flow of processing executed by the smartphone 1 according to the embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating a process flow of the smartphone according to the embodiment. The process shown in FIG. 6 is realized by the controller 10 executing the control program 9A stored in the storage 9. The process illustrated in FIG. 6 is repeatedly executed while the smartphone 1 is activated unless an operation for ending the process illustrated in FIG. 6 is performed.

  As shown in FIG. 6, the controller 10 acquires the measurement result of the atmospheric pressure sensor 17 (step S101).

  The controller 10 determines whether the own device has been immersed in water based on the measurement result of the atmospheric pressure sensor 17 (step S102). If the result of determination is that the controller 10 is not immersed in water (No at Step S102), the controller 10 returns to the processing procedure at Step S101.

  On the other hand, when the controller 10 is immersed in water as a result of the determination (step S102, Yes), the controller 10 activates the touch screen 2B (step S103).

  The controller 10 acquires the detection result of the touch screen 2B (step S104).

  Based on the detection result of the touch screen, the controller 10 determines whether the own device has come out of the water (step S105).

  If the result of determination is that the own device is not out of the water (No at Step S105), the controller 10 returns to the processing procedure at Step S104.

  On the other hand, the controller 10 determines whether a process is complete | finished when the own machine comes out of water as a result of determination (step S105, Yes) (step S106). For example, the controller 10 determines the end of the process shown in FIG. 6 when a situation in which it is unlikely that the device will land, such as when charging is started via the connector 14, is detected.

  When the controller 10 does not end the process as a result of the determination (No at Step S106), the controller 10 returns to the process procedure at Step S101.

  As a result of the determination, when the process is to be ended (step S106, Yes), the controller 10 ends the activation of the touch screen 2B (step S107) and ends the process shown in FIG.

  In the process shown in FIG. 6, the determination in step S105 may be repeatedly executed by the controller 10 at a predetermined timing, for example.

  In the above embodiment, when it is determined that the smartphone 1 has been immersed in water based on the change in atmospheric pressure, the smartphone 1 activates the touch screen 2B, and based on the change in capacitance measured by the touch screen 2B, Estimate whether the aircraft immersed in the water came out of the water. According to the embodiment, the touch screen 2 </ b> B is used after it is determined that the device has been immersed in water based on the change in atmospheric pressure. The smartphone 1 can determine the presence / absence of water landing of its own device and the presence / absence of water separation of its own device while suppressing power consumption.

  As described in the above embodiment, the smartphone 1 estimates the landing of its own device based on the change in atmospheric pressure, and estimates the water separation of its own device based on the change in capacitance. In consideration of further reducing power consumption, the smartphone 1 does not use the touch screen 2B with relatively high power consumption, but based on only the measurement result of the atmospheric pressure sensor 17 with relatively low power consumption. You may perform the process which estimates both the presence or absence of water landing and the presence or absence of water separation of an own machine. However, the smartphone 1 according to the embodiment does not execute the process of estimating the water separation of the own device based on the measurement result of the atmospheric pressure sensor 17, that is, the change in atmospheric pressure. The reason will be described below. 7 and 8 are schematic views of a partial cross section of the smartphone. FIG. 9 is a diagram illustrating another example of a change in atmospheric pressure measured by the atmospheric pressure sensor.

As shown in FIG. 7, the smartphone 1 includes a housing 100. The casing 100 is provided with a vent hole 20 at a position facing the atmospheric pressure sensor 17. On the outer surface of the vent hole 20, a vent valve made up of the sheet 30 and the cloth water retaining sheet 40 is installed. When the smartphone 1 is immersed in water, as shown in FIG. 8, a water droplet may be formed outside the ventilation valve or a water film may be formed due to the water retention function of the water retention sheet 40. There is a case where the ventilation of the ventilation hole 20 becomes insufficient, and the atmospheric pressure sensor 17 becomes unable to perform accurate measurement of atmospheric pressure. For example, as shown in FIG. 9, when the smartphone 1 is repeatedly landed and taken off, the difference between the pressure value when the smartphone 1 landed and the pressure value when the smartphone 1 was landed is It is clear from the fact that it gradually becomes smaller. For this reason, when the landing and the water separation of the smartphone 1 are repeated, it is difficult for the controller 10 to estimate the water separation of the own device based on the atmospheric pressure change. In the above embodiment, the smartphone 1 determines the water separation of the own device based on the change in the capacitance measured by the touch screen 2B, thereby determining the presence or absence of the water separation of the own device based on the atmospheric pressure change. The above-mentioned problem caused by the problem is solved. The vent hole 20 is an example of a hole. The water retaining sheet 40 is an example of a cloth member.

  In said embodiment, the smart phone 1 estimates the presence or absence of the water landing of an own machine based on an atmospheric pressure change, and estimates the presence or absence of water separation of an own machine based on the change of an electrostatic capacitance. As shown in FIG. 9, when the landing and water separation of the smartphone 1 are repeated in a short time, water drops or the like may be formed on the outside of the vent valve 20. Therefore, it is difficult to estimate not only the water separation of the own aircraft but also the water landing of the own aircraft after the second time. In the following embodiments, the smartphone 1 performs the first water landing estimation based on a change in atmospheric pressure measured by the atmospheric pressure sensor 17, and the second and subsequent water landing estimations are measured by the touch screen 2B. An example that is implemented based on the change in capacitance will be described. Thereby, the smart phone 1 can determine more accurately the presence / absence of water landing of its own device and the presence / absence of water separation of its own device.

  A certain smartphone 1 is different from the smartphone 1 according to the above embodiment in the points described below.

  The control program 9A estimates whether or not the device that has been immersed in water comes out of the water based on the detection result of the touch screen 2B, and then determines whether or not the device has been immersed in water again based on the detection result of the touch screen 2B.

That is, the controller 10 estimates the first landing of its own device based on the atmospheric pressure change measured by the atmospheric pressure sensor 17. Subsequently, the controller 10 estimates the water separation of the own device based on the change in capacitance measured by the touch screen 2B, and then measures the second and subsequent water landings and water separation of the own device using the touch screen 2B. An estimation based on the change in capacitance is performed.

  When the controller 10 performs the process of estimating the landing and water separation of the own device based on the detection result of the touch screen 2B, the controller 10 performs the process of estimating based on the detection point of the touch screen 2B and the output value at the detection point. To do. When the controller 10 performs a process of estimating water landing and water separation of the own device based on the detection result of the touch screen 2B, the controller 10 may periodically execute the process at a predetermined timing.

  The controller 10 acquires the detection result of the touch screen 2B (step S204).

  Based on the detection result of the touch screen 2B, the controller 10 determines whether the own device has come out of the water (step S205).

  As a result of the determination, the controller 10 returns to the processing procedure of step S204 when the own device is not out of the water (No in step S205).

  On the other hand, when the controller 10 has come out of the water as a result of the determination (step S205, Yes), the controller 10 determines whether to end the process (step S206). For example, the controller 10 determines the end of the process shown in FIG. 10 when a situation in which it is unlikely that the device will land, such as when charging is started via the connector 14, is detected.

  As a result of the determination, if the process is to be ended (step S206, Yes), the controller 10 ends the activation of the touch screen 2B (step S207) and ends the process shown in FIG.

  On the other hand, if the result of determination is that the process is not terminated (No at Step S206), the controller 10 acquires the detection result of the touch screen 2B (Step S208).

  Based on the detection result of the touch screen 2B, the controller 10 determines whether the own device has been immersed in water (step S209).

  If the result of determination is that the controller 10 is not immersed in water (No at step S209), the controller 10 returns to the processing procedure at step S208.

  On the other hand, if the controller 10 is immersed in water as a result of the determination (step S209, Yes), the controller 10 returns to the processing procedure of step S204.
