[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention measures a water pressure using a pressure sensor, obtains a water depth value from the result, and displays the depth value. The present invention relates to an information processing device for divers having a relative depth from the water depth value to the water depth value measured this time and a function of measuring / displaying in the device.

[0002]

2. Description of the Related Art A conventional information processing apparatus for divers, which is also called a dive computer equipped with a pressure sensor,
In diving mode (underwater), information required to ensure the safety of the diver with a certain algorithm, such as the current depth value and the time and safety until the excess inactive gas accumulated in the body is discharged The floating speed is calculated and displayed on a display unit such as a liquid crystal display panel.

In addition, an electronic timepiece equipped with a pressure sensor has not only a function of measuring an altitude value or a water depth value converted from a pressure value, but also a function of displaying water temperature, temperature, etc. converted from a temperature sensor. . However, although the current depth value and the dive time up to the present were displayed, the depth difference (relative depth) from the water depth point to another point in a certain time zone and the time required for that were not displayed. The user had to calculate whether he was diving at such a speed (pace allocation).

If calculation is not performed, rapid diving or deep diving for a long time leads to decompression diving, nitrogen poisoning and oxygen poisoning. When rapid ascending, decompression sickness is more likely to occur. Decompression sickness is mainly caused by the growth of bubbles in the tissues and blood of the body. The pressure increases as the diver dive. As the pressure increases, the diver will inhale higher pressure air. Breathing pressurized air will increase the amount of gas that dissolves in tissues and blood. As the surface floats, the pressure decreases, and the pressure of the gas dissolved in the body becomes higher than the pressure around it. In this case, the gas is in a supersaturated state and bubbles are formed to cause decompression sickness, which causes a safety problem.

[0005]

Therefore, the present invention has a function of measuring, calculating, and displaying the relative depth and the time required, without having to deal with the above-mentioned problems, so that the information for divers can be safely obtained. It is intended to provide a processing device.

[0006]

In order to solve such a problem, an information processing apparatus for divers according to the present invention has a timekeeping unit for measuring elapsed diving time and a water depth measuring unit for detecting a water depth value. A water depth value is detected by a water depth measurement unit corresponding to a predetermined diving time elapsed, a diving information storage unit that stores the water depth value and the diving elapsed time calculated by the water depth measurement unit, and a past water depth value. Depth difference calculation unit that calculates the relative depth difference from the current water depth value, relative depth difference storage unit that stores the relative depth difference, and the relative depth difference obtained from the relative depth difference calculation unit and whether or not the user floated or dived. A display, a time required for the movement, a display unit for displaying a water depth value at the start of measurement and a water depth value at the end of measurement of the water depth measurement unit relating to the relative depth difference calculation this time. .

Therefore, it becomes possible to grasp how much the water depth has changed with respect to the elapsed time of diving, and it is possible to prevent decompression sickness. In addition, the depth difference display displayed on the display unit is indicated by numbers and graphs, and the dive time and the fixed interval time for calculating the depth difference are also displayed, so that the pace of the user (diver etc.) You can easily grasp the speed because you can see whether you are floating or diving in the distribution.

The information processing apparatus for divers according to the present invention is characterized in that it has a function of displaying the graph so that the scale per unit can be enlarged or reduced. It is preferable that the scale per unit can be scaled up and down with respect to water depth and dive elapsed time.

According to the present invention, since the water depth change can be displayed on the entire display screen, it is possible to recognize important information at the time of performing a dangerous act that is judged to be related to decompression sickness, and to perform subsequent diving. Can be used as a reference.

Further, when the switch is turned on, the pressure sensor 4 which operates operates to read the ambient pressure and convert it into a voltage.

Next, this is processed by an analog / digital converter (hereinafter referred to as A / D converter) 5. A / D
The converter 5 converts the voltage signal into a digital signal, which the microprocessor (CPU) 1 reads. The microprocessor (CPU) 1 performs necessary mathematical or logical operations through a program based on the information processed by the digital signal.

ROM (Read Only Memory) 6 is a permanent memory that contains all programs. It is the ROM 6 that tells the microprocessor which of the programs to execute. The ROM 6 contains all constants such as the body compartment, half time, and maximum nitrogen partial pressure at which bubbles cannot be generated even when returning straight to the water surface, which is used to plan a no-decompression state.

A RAM (read / write memory) 7 has a storage function, and stores diving data and calculation results.

The timekeeping unit 3 for measuring the dive time measures the elapsed dive time for obtaining necessary data such as determining the calculated speed of the dive computer and storing and displaying the rest time and the dive time.

The detailed internal structure is shown in FIG.

In FIG. 2, the divers information processing apparatus has a display unit 2 for displaying each function, and a control / arithmetic unit 9 for performing processing in each mode and displaying according to the information.
And are configured. The display unit 2 includes a liquid crystal display panel 16 that displays information in each mode by liquid crystal, and a liquid crystal driver 15 that drives the liquid crystal display panel 16. Since the information processing device for divers displays the time and measures the diving time, the clock output from the oscillation circuit 20 is input to the control / arithmetic unit 9 through the frequency dividing circuit 19 and the time The counter 18 constitutes the time counting unit 3 that measures time in units of 1 second.

The information processing device for divers measures and displays the water depth value, and also measures the amount of nitrogen gas (inert gas) accumulated in the body from the water depth value and the dive time. The unit 10 includes an amplifier circuit 21 that amplifies the output signal of the pressure sensor 4 that detects water pressure, and an A / D converter 5 that converts an analog signal output from the amplifier circuit 21 into a digital signal and outputs the digital signal to the control unit. Composed. Further, the information processing device for divers has a notification device 13
The alarm unit 8 such as the vibration generator 14 and the vibration generator 14 is configured to generate an alarm sound, vibration, E
It is possible to transmit the information to the user (diver etc.) by blinking L or the liquid crystal display device.

In the present embodiment, the control / arithmetic unit 9 includes a CPU 1 that controls the entire apparatus and a control circuit 17 that controls the liquid crystal driver 15 and the time counter 18 under the control of the CPU 1, and the ROM 6 Each mode is realized by each process performed by the CPU 1 based on the program stored in the.

[Floating speed monitoring function] The information processing device for divers is configured to monitor the flying speed of the diver during the diving mode.
It is realized as the following configuration by utilizing the functions of M6, RAM7 and the like.

As shown in FIG. 3, in the divers information processing apparatus, the levitation speed measuring unit 22 for measuring the levitation speed during levitation based on the measurement result of the time measuring unit 3 and the measurement result of the water depth measuring means 10, and the levitation speed. The flying speed violation determination unit 24 that compares the measurement result of the measuring unit 22 with a preset flying speed reference 23 and issues a flying speed violation warning when the current flying speed is faster than the flying speed reference 23. It is configured. The levitation speed measurement unit 22 is the CPU shown in FIG.
1, ROM 6, RAM 7, notification device 13, vibration generation device 14, display unit 2 and the like.

In the embodiment of the present invention, the levitation speed violation determination unit 24 compares the levitation speed reference 23 for each water depth range stored in the ROM 6 as the levitation speed reference 23 with the current levitation speed, If the current ascent rate is faster than the ascent rate reference 23 corresponding to the current water depth, a method of displaying, generating an alarm sound from the alarm device 13, transmitting vibration from the vibration generator 14 to the diver, blinking the display, etc. The warning about the violation of the ascending speed is issued, and the warning about the violation of the ascending speed is stopped when the ascending speed returns to a state slower than the ascending speed reference 23. In the present embodiment, the following values are shown for each range of water depth as the above-mentioned levitation speed reference 23: Water depth range Floating speed standard value Less than 1.8 m No warning 1.8 m to 5.9 m 8 m / min (about 0.8 m / 6 seconds 6.0m-17.9m 12m / min (about 1.2m / 6sec) 18.0m or more 16m / min (about 1.6m / 6sec), that is, the same at deep water This is because even if you ascend at a ascent rate, the water pressure ratio before and after ascent per unit time is small, so even if you allow a relatively large ascent rate, you can sufficiently prevent decompression sickness. However, since the water pressure ratio before and after ascent per unit time is large even when ascending at the same ascent rate, only a relatively small ascent rate is allowed.

In the embodiment of the present invention, the flying speed reference 23
The water depth value per 6 seconds is stored in the ROM 6 because the water depth is measured every 1 second, but in order to prevent the movement of the arm equipped with the information processing device for divers from affecting the ascending speed. Since the levitation speed measurement is performed every 6 seconds, the difference between the current water depth measurement value and the previous water depth measurement value 6 seconds before is calculated, and this difference is calculated based on the levitation speed reference (m / 6
Second) 23.

Further, as shown in FIG. 3, in the divers information processing device, the water depth value measured by the water depth measuring unit 10 is 1.5 m from the time of diving deeper than 1.5 m (water depth value for judging diving start). The diving result (diving date and time, dive number, dive time, maximum water depth, water temperature data at maximum water depth) is stored in RAM 7 as one dive operation until it becomes shallower than (water depth value for judging the end of dive). The dive result storage unit 25 to be held is configured, and this dive result storage unit 25 is also shown in FIG.
It is realized as the functions of the CPU 1, ROM 6, and RAM 7 shown in FIG. Here, the dive result storage unit 25 indicates that there is a violation of the ascending speed when the ascending speed violation determining unit 24 issues a plurality of consecutive warnings in one dive, for example, two or more consecutive warnings. Is configured to be stored as a diving result.

The diving result storage unit 25 is a water depth measuring unit 1.
Based on the measurement result of the time measuring means 3 from the time when the water depth value measured by 0 is deeper than 1.5 m (water depth value for judging dive start) until it becomes shallower than 1.5 m (water depth value for dive end judgment). If the dive time is less than 3 minutes, the dive during this time is not treated as one dive,
Do not record the diving results during that time. This is because important diving results will be deleted if a short dive such as a dive is remembered.

As described above, in the information processing apparatus for divers according to the embodiment of the present invention, when the water depth is deeper than 1.5 m
The water depth is 1. When ascending to a position shallower than 5m, the water depth is considered to be 0m and the display is 0.
m. Therefore, when the ascending speed violation determining unit 24 issues a ascending speed violation warning even in such a shallow place as in a deep place, there is an arm movement of several cm at a place where the depth of water is slightly deeper than 1.5 m. If is considered to be 0 m, even if it is shallower than 1.5 m, the ascending speed violation warning will be issued even though the ascending speed is being maintained. As a result, divers question the reliability of ascent speed warnings. However, in the present embodiment, the current water depth is a predetermined value (usually set to 1.5 m or less, which is the water depth at which water walking is possible,
At a shallower depth (less than 1.5 m), the flying speed violation warning is not issued regardless of the flying speed. Therefore,
Since the above-mentioned unnatural warning is not issued, it is possible to enhance the reliability of this warning.

[Internal Nitrogen Calculation Method] FIG. 4 is a functional block diagram for explaining an example of the configuration for calculating the internal nitrogen partial pressure (hereinafter referred to as the internal nitrogen amount) in the diver's information processing apparatus of this embodiment. is there. The calculation of the amount of nitrogen in the body shown here is merely an example, and various methods can be used. Therefore, a configuration therefor will be briefly described here.

As shown in FIG. 4, in the information processing apparatus for divers of this embodiment, in order to calculate the amount of nitrogen in the body as the partial pressure, the pressure sensor 4, the amplifier circuit 21, A shown in FIG.
Water depth measuring unit 10 using the D / D converter 5, a respiratory air nitrogen partial pressure measuring unit 31 realized as a function of the CPU 1, the ROM 6 and the RAM 7 shown in FIG. 2, and the body nitrogen content using the RAM 7 shown in FIG. The pressure storage unit 36, the clock unit 3 using the clock counter 18 shown in FIG. 2, and the CPU shown in FIG.
1. Comparing unit 33, which is realized as a function of ROM 6 and RAM 7, and compares the data stored in respiratory air nitrogen partial pressure storage unit 32 and internal nitrogen partial pressure storage unit 36, CPU 1 shown in FIG. 2, ROM 6, A half-saturation time selection unit 34 realized as a function of the RAM 7 is configured. Of these components, the respiratory air nitrogen partial pressure measurement unit 31, the internal nitrogen partial pressure calculation unit 35, the comparison unit 33, and the half-saturation time selection unit 34 are realized as software by the CPU 1, the ROM 6, and the RAM 7 of FIG. It is possible, but it is also possible to realize it by only a logic circuit which is hardware, or by combining a logic circuit and a processing circuit including a CPU and software.

In this configuration example, the water depth measuring unit 10 measures and outputs the water pressure P (t) corresponding to the time t.

The respiratory air nitrogen partial pressure measuring unit 31 calculates and outputs the respiratory air nitrogen partial pressure PIN ₂ (t) based on the water pressure P (t) output from the water depth measuring unit 10. The respiratory air nitrogen partial pressure PIN ₂ (t) can be calculated from the water pressure P (t) in the dive by the following equation PIN ₂ (t) = 0.79 × P [bar].

The respiratory air nitrogen partial pressure storage unit 32 stores the PIN calculated by the respiratory air nitrogen partial pressure measurement unit 31 as the above equation.
₂ Store the value of (t).

The internal nitrogen partial pressure calculator 35 absorbs nitrogen /
Nitrogen partial pressure PGT (t) in each tissue with different excretion rate
To calculate. Taking one organization as an example, the dive time t = t
Tissue nitrogen partial pressure PGT to absorb / discharged from ₀ to t _E (t
_E) includes, and the dive time t _E t ₀ o'clock tissue nitrogen partial pressure PGT (t _0), is calculated from the half-saturation time T _H. Then, the result is stored in the internal nitrogen partial pressure storage unit 36 as PGT (t _E ). The calculation formula for that is as follows. PGT (t _E ) = PGT (t ₀ ) + {PIN ₂ (t ₀ ) −P
GT (t ₀ )} × {1-exp (−k (t _E −t ₀ ) /
_TH )} Here, k is a constant that is experimentally obtained.

Next, the comparison unit compares PIN ₂ (t), which is the result of the respiratory air nitrogen partial pressure storage unit 32, with PGT (t), which is the result of the internal nitrogen partial pressure storage unit, and as a result, The saturation time selection unit 34 makes the half saturation time T _H used in the internal nitrogen partial pressure calculation unit 35 variable. For example, t =
t ₀ o'clock in the breathing gas nitrogen partial pressure PIN ₂ (t _0), the body nitrogen partial pressure PGT (t _0), respectively breathing gas nitrogen partial pressure storage unit 32
And the internal nitrogen partial pressure storage unit 36,
The comparison unit 33 compares this PIN ₂ (t ₀ ) with PGT (t ₀ ).

The internal nitrogen partial pressure calculating unit 35 is controlled by the half-saturation time selecting unit 34 as follows, and t = t.
_The nitrogen partial pressure PGT (t _E ) in the body at the time of _E is calculated. When PGT (t ₀ )> PIN ₂ (t ₀ ), PGT (t _E ) = PGT (t ₀ ) + {PIN ₂ (t ₀ ) −P
GT (t ₀ )} × {1-exp (−k (t _E −t ₀ ) / T
_H1 )} PGT (t ₀ ) <PIN ₂ (t ₀ ), PGT (t _E ) = PGT (t ₀ ) + {PIN ₂ (t ₀ ) −P
GT (t ₀ )} × {1-exp (−k (t _E −t ₀ ) / T
_H2 )} Here, in the above two expressions, k is a constant, and T _H2 <T _H1 is calculated.

When PGT (t ₀ ) = PIN ₂ (t ₀ ), the half-saturation time TH is preferably calculated as TH = (TH ₂ + TH ₁ ) / 2. In addition, these times (measurement for t ₀ and t _E ) are managed by the timer unit in FIG.

Here, PGT (t ₀ )> PIN ₂ (t ₀ ).
Is the case where nitrogen is excreted from the body, and PGT
When (t ₀ ) <PIN ₂ (t ₀ ), nitrogen is absorbed into the body. Changing the half-saturation time at these times means that if nitrogen is discharged, the half-saturation time is long and it takes time to discharge it. Conversely, if nitrogen is absorbed, half-saturation time is changed. Is short, and the time required for absorption is shorter than the time required for discharge. In this way, it is possible to set the upper limit of the amount of nitrogen in the body from the body nitrogen partial pressure discharge time deriving unit 37 after the decompression available time or the water surface has risen from the current amount of nitrogen in the body. The time required for the amount of nitrogen to return to the normal state can be calculated. Therefore, the safety of diving can be enhanced by notifying the user of such information.

[Diving Mode] FIGS. 5 to 8 show a mode configuration diagram and its display example in the diving state in the information processing apparatus for divers of this embodiment. Diving (when the diving operation monitoring switch 12 is ON), dive time measurement, water depth measurement, ascent speed warning processing, dive mode processing M3 such as calculation of non-decompression dive time and relative depth is performed at any time, and normal display As shown in FIG. 6 as the processing, from the current water depth, the deepest water depth (maximum water depth) during diving, the diving time, and the calculated available body nitrogen amount shown in FIG. Required non-decompression dive time (ND

The display E3 of this embodiment indicates that the current water depth is 15.8 m and the current time is 14:30:58.

By continuing to press the switch S3 from the switch input judging process M4, the mode is changed and the display is switched. As a display D4, the relative depth for each measurement interval, the relative depth measurement interval time, and the water depth value at the start / end are shown. Example E4
Dives to a relative depth of 2.0 m, and the water depth value at the start of measurement is 1
The water depth is 3.5 m, the water depth at the end of the measurement is 15.5 m, and the measurement interval time is 6 seconds. The relative depth is constantly measured during diving at certain fixed intervals or at set intervals, and the switch display can be easily switched when the user wants to see it.

The water depth at that time is stored in the dive at regular intervals. The horizontal axis is a bar graph G1 (hereinafter referred to as a dive pattern) showing the relationship between the dive time when memory is stored and the vertical axis is the water depth value at that time so that the diving situation can be seen at a glance.
It is displayed on the display unit 2 as shown in (a), (b) and FIGS. 8 (c), (d). By doing this, the diving situation up to the local point during diving and the water depth value at the time of diving at the time of measurement can be known, and the diving pattern at the time of the last diving can be compared to determine what kind of diving pattern is safe. You can grasp the tendency.

Further, in the display of the line graph G2, since it is a line connecting the previous water depth value and the current water depth value at each measurement interval, if there is a change in depth, the relative depth can be known from the inclination. .

The graph displayed on the display unit 2 also has a function of changing the scale of the water depth per unit of the graph and the diving time according to the water depth value for each measurement. Examples are shown in FIGS. 7 (a) and 7 (b) and FIGS. 8 (c) and 8 (d). The horizontal axis G4 shows the diving time (minutes), and the vertical axis G3 shows the water depth (m).

The scale per unit of the water depth value (m) and the diving time (minute), which are the vertical axis G3 and the horizontal axis G4, can be enlarged or reduced. In this embodiment, the scale of the depth value (m) on the vertical axis G3 is 2 m per unit, and the scale of the diving time (min) on the horizontal axis G4 is 1 minute, as shown in FIG. 8C. By enlarging and reducing the scale as shown in (d) of 8, the scale per unit of the vertical axis G3 is 1 m and the scale per unit of the horizontal axis G4 is 2 minutes. In this way, the display scrolls to make the graph easier to see, and the data until the end of the dive can be graphed. Further, by enlarging and reducing the scale per unit on the display unit 2 of the liquid crystal, there is an effect that the diving situation can be displayed on one screen. In the case of a floating warning, when the water depth value for each measurement time is graphed, the place where the floating warning is performed is notified by blinking etc., so that the battery consumption is less than the notification method that notifies by sound of an alarm or lighting such as EL Is advantageous.
As described above, the diving pattern is graphed together with the diving time, and a safe diving pattern is also displayed as a future predicted diving from the current water depth point.
