As shown in FIGS. 3 and 4, the diving waterproof housing 100 may include an opening and closing member 110, an input member 120, and a shielding member 130.

The diving waterproof housing 100 can be opened and closed through the opening and closing member 110, and according to one embodiment, it is composed of a hinge and can be opened and closed by rotating about the longitudinal direction of the opening and closing member 110.

The diving waterproof housing 100 includes a plurality of input members 120 on one side, and in a state in which the mobile terminal 200 and the outside are shielded underwater, the mobile terminal 200 is connected to the mobile terminal 200 through the input member 120.

The external bulkhead is made of a hard material with little change in volume, and the airbag is connected to the inside of one side of the waterproof diving housing 100 and can be contracted and expanded according to external pressure.

As the water depth changes, the airbag contracts and expands in response to the external pressure of the waterproof diving housing (100), and is connected to the inside of one side of the waterproof diving housing (100), so the air present in the airbag is stored in the waterproof diving housing (100). It is possible to move between the interior of (100) and the airbag.

Specifically, when moving from shallow water to deep water, the external pressure becomes relatively high, so the air in the elastic airbag is automatically transferred to the inside of the waterproof diving housing 100 by the external pressure of the waterproof diving housing 100. can be brought in.

Through this, even if the external pressure of the diving waterproof housing 100 changes, the internal pressure of the diving waterproof housing 100 is almost the same as the external pressure due to the deformation of the airbag attached to the diving waterproof housing 100. can be maintained, improving waterproofing performance.

In addition, the waterproof diving housing 100 may include a valve (not shown) that can be selectively adjusted by introducing air into the interior of the waterproof diving housing 100 through an airbag.

Additionally, storage 220 may include a network attached storage device accessed through a network.

The sensor unit 230 detects the measured internal pressure of the diving waterproof housing (1).

Here, the sensor unit 230 may be a pressure sensor capable of detecting internal pressure, and the internal pressure represents water pressure.

The sensor unit 230 may be included and implemented inside the mobile terminal 200, or may be provided attached to the outside of the mobile terminal 200.

The sensor unit 230 may transmit the sensed internal pressure to the control unit 240 through the communication unit 210.

The control unit 240 determines the final water depth at which the diving waterproof housing 100 is located based on the sensed internal pressure.

In one embodiment of the present invention, the final depth of water is determined based on the measured internal pressure of the waterproof housing 100 for diving that does not include an airbag.

In an embodiment in which an airbag is not included, as shown in FIG. 6, the control unit 240 matches the sensed measured internal pressure with a standard internal pressure of one of the pre-stored standard internal pressure data, and stores the pre-stored standard internal pressure. The standard water depth corresponding to one standard internal pressure matched among the water depth data can be determined as the final water depth.

Here, the standard internal pressure data and standard water depth data are composed of a plurality of internal pressure values and a plurality of standard water depth values, and can be prepared with data actually measured underwater, and the standard internal pressure data is so that it corresponds to each standard water depth. It can be saved.

In the present invention, the standard water depth according to the standard internal pressure is visualized as a graph for easy understanding, but the data can be processed and stored using a look-up table, etc.

For example, if the detected measured internal pressure is 2 bar, the control unit 240 matches the measured internal pressure with the standard internal pressure of one of the pre-stored standard internal pressure data, and matches the standard internal pressure of one of the pre-stored standard internal pressure data. By extracting the standard water depth corresponding to 20m, the standard water depth can be determined as the final water depth.

In another embodiment in which an airbag is not included, as shown in FIG. 6, the control unit 240 calculates the slope of the sensed measured internal pressure according to a preset cycle and determines the final water depth based on the slope of the sensed measured internal pressure. can be decided.

The control unit 240 matches the slope of the measured internal pressure with the slope of the standard internal pressure of one of the previously stored standard internal pressure slope data, and sets the standard water depth corresponding to the slope of the matched standard internal pressure among the standard water depth data. It can be determined by the final water depth.

Here, the standard internal pressure slope data and standard water depth data may be stored based on data actually measured underwater, and the standard internal pressure slope data may be stored in advance to correspond to each standard water depth.

In addition, in another embodiment of the present invention, the final depth of water can be determined based on the internal pressure of the waterproof housing 100 for diving including an airbag.

In one embodiment when an airbag is included, as shown in FIG. 7, the control unit 240 matches the sensed measured internal pressure with a standard internal pressure for an airbag of one of the standard internal pressure data for an airbag stored in advance, The final water depth can be determined based on the standard water depth for the airbag corresponding to the standard internal pressure for one airbag matched among the standard water depth data for the pre-stored airbag.

Here, the control unit 240 can set the reference standard water depth.

The control unit 240 may determine whether the extracted standard water depth for the airbag exceeds the reference standard water depth.

For example, as shown in FIG. 7, the standard standard water depth can be set to 18 m, and if the extracted standard water depth for the airbag is less than the standard standard water depth, the control unit 240 can determine the extracted standard water depth for the airbag as the final water depth.

If the extracted standard water depth for the airbag exceeds the standard standard water depth, the control unit 240 calculates the slope of the measured internal pressure detected according to a preset cycle, and changes the slope of the measured internal pressure to the slope of the pre-stored standard internal pressure for the airbag. It matches the slope of the standard internal pressure for an airbag among the data, and the standard water depth for the airbag corresponding to the slope of the standard internal pressure for the matched airbag among the standard water depth data for the airbag can be determined as the final water depth.

In another embodiment where an airbag is included, the control unit 240 determines whether the sensed measured internal pressure exceeds a preset threshold.

Here, the threshold value can be set by considering the section where the standard internal pressure rapidly increases due to the airbag.

If the measured internal pressure is below the threshold, the measured internal pressure is matched with the standard internal pressure for one airbag among the standard internal pressure data for airbags stored in advance, and the standard internal pressure for one airbag matched among the standard internal pressure data for airbags is matched. The standard water depth for airbags can be determined as the final water depth.

When the sensed internal pressure exceeds the threshold, the control unit 240 matches the slope of the measured internal pressure detected at a preset cycle with the slope of the standard internal pressure for one airbag among the slope data of the standard internal pressure for an airbag stored in advance. , the standard water depth for an airbag corresponding to the slope of the standard internal pressure for one airbag matched among the standard water depth data for airbags can be determined as the final water depth.

In this way, the waterproof device for diving (1) measures only the internal pressure of the waterproof housing for diving (100) using the pressure sensor built into the mobile terminal (200) without a separate external pressure sensor and determines the current position in the water. The final water depth can be determined.

Additionally, the control unit 240 performs verification of the final water depth determined.

In one embodiment, the control unit 240 extracts a standard external pressure corresponding to a standard water depth extracted from pre-stored standard external pressure data, and the difference between the measured internal pressure and the standard external pressure is the difference between the standard internal pressure and the standard external pressure. It can be verified by comparing .

Here, the standard internal pressure represents the standard internal pressure matched to the measured internal pressure.

As shown in FIG. 8, the control unit 240 extracts the standard external pressure corresponding to the standard water depth from the pre-stored standard external pressure data, and the difference between the measured internal pressure and the standard external pressure is included in the preset reference pressure difference range. It can be verified by determining whether it is possible.

Here, the reference pressure difference range may be predetermined based on the difference between the standard internal pressure and the standard external pressure.

In another embodiment, the control unit 240 may determine and verify whether the slope of the measured internal pressure deviates from a preset critical range.

Here, the critical range can be set in advance based on the slope of the standard internal pressure.

If the slope of the measured internal pressure is outside the critical range, the control unit 240 may recognize it as a measurement error and remeasure the internal pressure of the waterproof diving housing 100 to determine the final depth.

In this way, even when the mobile terminal 200 verifies the final depth using the waterproof housing 100 for diving including an airbag, as shown in FIG. 7, the control unit 240 stores the standard external pressure data stored in advance. The standard external pressure corresponding to the standard water depth for the airbag extracted from the airbag can be extracted, and the difference between the measured internal pressure and the standard external pressure can be verified by comparing the difference between the standard internal pressure and the standard external pressure.

Additionally, the control unit 240 may determine and verify whether the slope of the measured internal pressure deviates from a preset critical range.

The control unit 240 may transmit the determined final water depth to the I/O module 250 through the communication unit 210.

The control unit 240 functions as a central processing unit, and the type of central processing unit may be a microprocessor. A microprocessor is equipped with an arithmetic logic operator, a register, a program counter, an instruction decoder, a control circuit, etc. on at least one silicon chip. It is a processing device.

Additionally, the microprocessor may include a graphics processor (Graphic Processing Unit, GPU) for graphic processing of images or videos. A microprocessor can be implemented in the form of a SoC (System On Chip) that includes a core and GPU. Microprocessors may include single core, dual core, triple core, quad core, and multiple cores.

Additionally, the control unit 240 may include a graphic processing board including GPU, RAM, or ROM on a separate circuit board electrically connected to the microprocessor.

As shown in FIG. 9, the I/O module 250 displays the determined final water depth information.

The I/O module 250 may display the determined final water depth as the current water depth.

As shown in FIG. 10, the I/O module 250 may display a rest notification when the final determined water depth reaches a preset reference water depth.

Here, the preset standard water depth may be 5m, 10m, 15m, 20m, 25m, 30m, 35m, etc.

The I/O module 250 displays an error notification and a depth remeasurement notification when the difference between the measured internal pressure and the standard external pressure is outside the preset reference pressure difference range or when the slope of the detected internal pressure is outside the critical range. You can do it.

As shown in FIG. 11, the I/O module 250 may provide a depth measurement error notification and simultaneously display a remeasurement progress notification.

The I/O module 330 is implemented as a screen to check final water depth information, notifications, etc., and may include a touch screen, a graphic module, a contact module, and a motion module.

Additionally, the point of contact between the touch screen and the user may correspond to the width (digit) of one or more of the user's fingers.

The touch screen may use LED (Light Emitting Diode) technology, LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology. In addition, various display technologies can be used as examples of technologies used in touch screens.

The touchscreen uses multiple touch sensing technologies such as capacitive, resistive, infrared, and surface acoustic technology, as well as a proximity sensor array to determine the point of contact with the touchscreen. Different elements can be used to detect contact and movement or interruption.

Additionally, the user may contact the touch screen using an appropriate object or attachment, such as a stylus or finger.
