(4) Method of calculating various theoretical values Next, a method of calculating various theoretical values regarding diving will be briefly described. First, a method of calculating the partial pressure of the inert gas in the body will be described. For the calculation method of the partial pressure of the inert gas in the body performed in the present embodiment, for example, KEN LOYST et a
l.'s "DIVE COMPUTERS A CONSUMER'S GUIDE TO HISTO
RY, THEORY & PERFORMANCE '' Watersport Publishing In
c. (1991) and AA Buhlmann's "Decompression-Decomp
ression Sickness "(especially page 14), Springer, Berli
n (1984). The method of calculating the partial pressure of the inert gas in the body shown here is merely an example, and various methods other than this can be used.

First, based on the water depth d (t) corresponding to the time t, the partial pressure of the inert gas in the gas breathed by the user (hereinafter, referred to as breathed air) (hereinafter, the breathed air inert gas content). The pressure PIN2 (t) is calculated by the following equation. PIN2 (t) = (10 + d (t)) × (1-FO2) [msw] ... “FO2” in the equation is a numerical value indicating the ratio of oxygen in the respiratory air, and is hereinafter referred to as the oxygen ratio. In the present embodiment, the gas other than oxygen is regarded as an inert gas such as nitrogen or helium, and thus "1-FO2" is a numerical value indicating the proportion of the inert gas in the respiratory air. The unit "msw" of the inert gas partial pressure is the atmospheric pressure at an altitude of 0 m of 10 "msw". Therefore, if the altitude of the dive area is 0 m, the formula can be used as it is, for example, an altitude of 800 m or 1
In diving at a height of 600 m, the value of “10” in the formula is smaller.

It is generally known that nitrogen and oxygen are formed in the air in a volume ratio of about 0.79: 0.21. Therefore, when the tank is filled with air and used, FO2 becomes 0.21. Also,
So-called Nitrox is a gas in which the oxygen ratio is larger than that of air, and generally nitrogen and oxygen are approximately 0.
The volume ratio is 68: 0.32 or 0.64: 0.36. The so-called Trimix is a gas in which helium is mixed in addition to nitrogen and oxygen, and for example, nitrogen: oxygen: helium = 0.34: 0.16: 0.
The volume ratio is 50.

When the respiratory-air inert gas partial pressure PIN2 (t) is calculated as described above, then, the in-vivo inert gas content is different for each body tissue having different absorption / exhaust rates of the inert gas. The pressure is calculated. Here, muscle, fat, brain,
The partial pressure of inert gas in the body is calculated by classifying into nine tissues such as nerves and bones. For example, taking a certain tissue as an example, the partial pressure PGT (t) of the inactive gas absorbed / exhausted by the dive time 0 to t is calculated as the partial pressure PGT of the inactive gas at the start of calculation (t = 0). (0) is calculated by the following equation. PGT (t) = PGT (0) + {PIN2 (0) -PGT (0)} * {1-exp (-Kt / HT)} ... Here, K is a constant obtained experimentally. Also, H
T is the time until the inert gas melts into each tissue and reaches half of the saturated state (hereinafter referred to as half-saturation time),
This is a different value for each organization. This half saturation time HT
Becomes variable depending on the magnitude of PGT (0) and PIN2 (0). This depends on the magnitude of PGT (0) and PIN2 (0), and it is determined whether the inert gas tends to be discharged or absorbed, but the half-saturation time is required for the discharge and absorption of the inert gas. Because they are different.

The half-saturation time HT also differs depending on the type of inert gas (for example, nitrogen or helium). Regarding the above-mentioned Trimix, the inert gas partial pressure PG in the body
When obtaining T (t), first, the partial pressure of nitrogen in the body (hereinafter,
Determine the partial pressure of nitrogen in the body and the partial pressure of helium (hereinafter, the partial pressure of helium in the body). Then, the partial pressures of nitrogen in the body and the partial pressure of helium in the body are added to calculate the final partial pressure of the inert gas in the body. When two or more kinds of inert gas are mixed in the breathing air as described above, first, the calculation is performed by paying attention to each inert gas, and then the calculation results are summed to obtain a numerical value for the entire inert gas. To calculate. The same idea applies to the following description.

Next, the non-decompressible dive time (Non Decompr
The method of calculating the ession limit (hereinafter referred to as NDL) will be described. The non-decompressible dive time is calculated by obtaining the time t when PGT (t) calculated in the formula becomes Ptol indicating the allowable supersaturated inert gas amount of each tissue. This Ptol has a different value depending on the altitude of the diving area. Because the higher the altitude of the diving area, the smaller the atmospheric pressure, the larger the volume of the inert gas accumulated in the body, and the more likely it is to bubble (that is, the more likely it is to become decompressive). This is because it must be set to a small value. In the present embodiment, the altitude of the diving area is roughly divided into four ranks, and Ptol is predetermined for each altitude rank. Specifically, altitude 0m (altitude rank 0), 800m (altitude rank 1), 1600m (altitude rank 2), 2400m
The altitude rank is defined as (altitude rank 3). Now, in the equation, if PGT (t) = Ptol, then t = −HT × (ln (1-f)) / K. However, f = (Ptol-PGT (0)) / (PIN2 (0)-
PGT (0)). With this formula, all non-decompression diving possible times in each tissue are calculated, and the smallest value among them is the no-decompression diving possible time to be obtained.

Next, a method for calculating the in-body inert gas discharge time until the in-body inert gas is discharged after the surface of the water is floated will be described. To calculate the inactive gas discharge time in the body, the above-mentioned PGT (t) = PGT (0) + {PIN2 (0) -PGT (0)} x {1-exp (-Kt / HT)} ... In, the time t at which PGT (t) = 0 is obtained. However, in the exponential function like the above equation, PGT (t) = 0 is not satisfied unless the time t becomes infinite. Therefore, for convenience, the following formula is used to expel the inert gas discharge time tZ in the body Is calculated. tZ = -HTxln (1-f) / K ... However, it is f = (Pde-PIN2) / (7.9-PIN2). Here, HT is the above-mentioned half-saturation time, and P
de is an inert gas partial pressure regarded as residual inert gas discharge for each tissue, and these are all known values. In addition,
The inert gas partial pressure on the water surface (that is, in the atmosphere) is 10 ×
It is set to 0.70 = 7.9 (msw). Also, PIN
2 is the partial pressure of the inert gas in each tissue at the end of the dive. The tZ is calculated for each tissue by the above formula, and the largest value among them is the inert gas discharge time in the body. The above is the calculation method of various theoretical values.

B: Operation Next, the operation of the embodiment having the above configuration will be described. FIG. 5 is a flowchart showing the flow of processing of the CPU 101 of the PC 100. In FIG. 5, when the user operates the operation unit 105 to instruct activation of the diving program 106 a, the CPU 101
A GUI (not shown) is displayed on the display unit 104 by reading the diving program 106a from the hard disk device 106 (step S1).

The GUI is provided with input fields for inputting various scheduled diving data, and the user inputs data indicating the contents of the scheduled diving in these input fields. Here, altitude rank “0”, FO2 “21” (here, oxygen ratio 0.21 is multiplied by 100 and expressed as “21”) is input as the dive schedule data, and further specific diving As a pattern, it moves to a depth of 40 m by 1 minute after the start of dive, stays at a depth of 40 m until 8 minutes after the start of dive, moves to a depth of 20 m by 9 minutes after the start of dive, and reaches a depth of 20 minutes until 26 minutes after the start of dive.
It stays at m, moves to a depth of 10 m by 27 minutes after the start of diving, stays at a depth of 5 m until 41 minutes after the start of diving, and starts to float to the water surface at the time of 41 minutes, and at 42 minutes after the start of diving. It is assumed that the data that will surface is entered.
When the CPU 101 detects that these dive schedule data are input (step S2), the input data is stored (step S3).

Next, the CPU 101 initializes the values of the dive time t and the water depth d (t) to "0" (step S4),
The processing shifts to the following. In the following calculation, the sampling period is 1 minute.

First, the CPU 101 starts the dive (t =
The inert gas partial pressure PGT (0) of 0) is calculated by the above-mentioned formula (step S5). Next, the CPU 101
Increments the dive time t by 1 (minute) (step S6), and calculates the water depth d (t) 1 minute after the start of the dive (step S7). This water depth d (t) is the time t in the diving pattern previously input by the user.
It is determined by referring to the water depth corresponding to.

Next, the CPU 101 calculates the calculated d (t).
Substituting PIN2 (t) into the formula, the amount of inert gas PGT (t) in the body 1 minute after the start of diving
Is calculated (step S8). Next, the CPU 101
It is determined whether or not the calculation has been performed until the end of the dive (step S9).

If the calculation has not been completed until the end time (step S9; No), the PGT (t) calculated in step S8 is set as PGT (0) (step S1).
0), the process returns to step S6 again, and this time, calculation is performed 2 minutes after the start of diving. That is, the CPU 101 determines from the start of diving to the end of diving (in this case, 9
Until the time (minutes have elapsed), the processes of steps S6 to S10 are repeatedly executed until all the calculations for every one minute of the sampling cycle are performed.

When all the calculations up to the end of the dive are completed (step S9; Yes), the CPU 101 displays the calculation result on the display unit 104 (step S1).
1).

FIG. 6 is a diagram showing an example of the GUI displayed at this time. In FIG. 6, the diving pattern input by the user is displayed in a line graph format in the diving pattern display area F1. The vertical axis of this line graph is the water depth,
The horizontal axis shows the dive time. The intersection P of the thick chain lines L1 and L2 can be freely moved on the line graph by the user operating the operation unit 105. One point on the line graph indicated by the intersection P indicates the "current time", and various information at this time is displayed in the display areas F2 and F3. Current nitrogen amount display area F
In FIG. 2, the allowable inert gas partial pressure Ptol in each tissue is used as the denominator, and the numerical value in which the in-vivo inert gas partial pressure PGT in each tissue at the present time is used as the numerator is displayed in a bar graph in percentage format. Here, nine bar graphs corresponding to nine tissues such as muscle, fat, brain, nerve, and bone are displayed. In the dive data display area F3, in addition to the current dive time, water depth and non-decompression dive time (NDL), decompression stop water depth in the case of decompression diving, decompression stop time and total ascent time, the internal nitrogen graph and body The oxygen graph is displayed.
In addition, the internal nitrogen graph and the internal oxygen graph show the approximate level of nitrogen or oxygen absorbed at the present time when the internal permissible nitrogen partial pressure and the internal permissible oxygen partial pressure are set to "9", respectively. It is a numerical value indicating that. In FIG. 6, at the present time indicated by the intersection P of the thick chain lines L1 and L2, the diving time is “26 minutes” and the water depth is “20.
0 m ”, NDL“ 1 minute ”, internal nitrogen graph“ 7 ”, and internal oxygen graph“ 1 ”.

Next, the CPU 101 stores the maximum water depth (40 m in this case) in the dive pattern and the dive time (41 minutes in this case) until the start of ascent as notification data in the hard disk device 106 (step S12).

After that, the CPU 101 waits for an input operation by the user, and when some operation is performed (step S13; Yes), the CPU 101 performs a process corresponding to the operation.
For example, when the user performs an operation for instructing data transfer, the CPU 101 stores the diving schedule data input in step S2, the data indicating the result of the simulation performed in steps S5 to S9, and the data stored in step S11. The notification data is transmitted to the dive computer 1 via the communication unit 62 (step S1).
4). On the other hand, the dive computer 1 stores the above-mentioned transmitted data in the RAM 54. On the other hand, when the operation to terminate the program is performed in step S13, the CPU 101 terminates the software (step S15).

Next, referring to the flow shown in FIG.
The flow of processing when the CPU 51 of the dive computer 1 notifies that the maximum water depth has been reached will be described. If the pressure sensor 34 described above determines that the diving has started when the water pressure (water depth) becomes equal to or greater than 1.5 [m] at the water depth, the flow shown in FIG. 7 is started.

The CPU 51 repeatedly takes in the water pressure detected by the pressure sensor 34 at a predetermined sampling cycle, and the taken water pressure is equal to or more than the water pressure corresponding to the maximum water depth (here, 40 m) stored as notification data in the RAM 54. It is determined whether or not (step S21).

Here, when the CPU 51 determines that the taken water pressure is equal to or higher than the water pressure corresponding to the maximum water depth (step S21; Yes), it notifies the user that the maximum water depth has been reached (step S22). Specifically, the CPU
51 outputs an alarm sound having a frequency of 8 Hz for 5 seconds from the alarm device 37 and controls the liquid crystal driver 12 to blink the current water depth displayed on the liquid crystal panel 11. FIG. 8 shows the liquid crystal panel 11 of the dive computer 1 at this time.
It is the figure which illustrated the information displayed on. In Figure 8, dive time "1 minute", current water depth "40.0m", ND
L is "8 minutes", and further, the numerical value of "40.0" indicating the water depth blinks. The user can know that he / she has reached the planned maximum water depth by such alarm sound and blinking of the water depth display.

Next, referring to the flow shown in FIG.
The flow of processing when the CPU 51 of the dive computer 1 reports the dive time until the start of ascent will be described. When the pressure sensor 34 described above determines that the diving has started when the water pressure (water depth) becomes equal to or greater than 1.5 [m] at the water depth, the flow shown in FIG. 9 is started.

The CPU 51 monitors the dive time measured by the timer 68, and the dive time is stored in the RAM 5
It is determined whether or not the dive time (41 minutes in this case) before the start of ascent stored in 4 as the notification data is longer than that (step S31).

Here, when the CPU 51 determines that the measured dive time is longer than or equal to the dive time until the start of the ascent (step S31; Yes), it informs the user that the ascent should be started (step S32). Specifically, the CPU
51 outputs an alarm sound having a frequency of 8 Hz from the alarm device 37 for 5 seconds and controls the liquid crystal driver 12 to blink the dive time displayed on the liquid crystal panel 11. FIG. 10 shows the liquid crystal panel 1 of the dive computer 1 at this time.
It is the figure which illustrated the information displayed on 1. In FIG. 10, the dive time is “41 minutes”, the current water depth is “10.0 m”,
NDL is “80 minutes”, and further, “4” indicates the dive time.
It shows that the numerical value of "1" blinks. The user can recognize that the user has reached the scheduled start-up time by the alarm sound and the blinking display of the dive time.

According to the above-described embodiment, the user does not need to perform various setting operations in advance in order to notify various information during diving, which is very convenient.

C: Modified Example (1) Kind of Notification Data In the above embodiment, the maximum water depth and the dive time until the start of ascent are reported, but the notification target is not limited to these. For example, when the partial pressure of the inert gas in the body becomes larger than a predetermined threshold value, the fact may be notified. That is, the dive computer 1
It is possible to calculate the partial pressure of the inert gas inside the body that actually accumulates in the user's body during a dive, so when this partial pressure of the inert gas falls below the threshold value, some warning display will blink. While outputting the alarm sound.

Further, when the non-decompressible dive time becomes smaller than a predetermined threshold value (for example, 3 minutes), the fact may be notified. That is, the dive computer 1 calculates the internal inert gas partial pressure actually accumulated in the user's body during the dive, and further calculates the non-decompressible dive time based on the internal inert gas partial pressure. Therefore, when the non-decompression dive time becomes equal to or less than the threshold value, an alarm sound may be output while blinking the numerical value. Note that the number of thresholds is not limited to one, and a plurality of thresholds may be set and a notification to that effect may be given each time each threshold is reached.

When diving such as exchanging with a tank having a different mixing ratio during diving, the fact may be notified when the tank should be exchanged or the water depth is reached. For example, when diving as shown in FIG. 6, a tank filled with Trimix is used at a dive time of 0 to 10 minutes, and after a dive time of 10 minutes (equivalent to reaching a water depth of 20 m in FIG. 6). It is assumed that the tank is replaced with a tank filled with Nitrox, and further, the tank is replaced with a tank filled with air after a dive time of 26 minutes (equivalent to reaching a water depth of 10 m in FIG. 6). In this case, the dive computer 1 has a dive time of 10
When minutes pass or when the water depth reaches 20 m, an alarm sound is output while blinking a warning that the tank filled with nitrox should be replaced. Also, the dive computer 1 outputs an alarm sound while blinking a warning that a tank filled with air should be replaced when the dive time of 26 minutes elapses or when the water depth reaches 10 m.

(2) Case where a plurality of dives are continuously performed In the embodiment, it is assumed that the diving is performed only once.
Of course, it does not matter even if a plurality of dives are continuously performed. When performing such a plurality of dives, it is necessary to carry out the calculation in consideration of the inert gas accumulated in the body due to the previously performed diving.
Since such a calculation method is a well-known matter, its explanation is omitted.

(3) Program Embodiment The embodiment has been premised on that the diving program 106a for performing the various operations described above is stored in the hard disk device 106 of the PC 100. However, not limited to this, the diving program 106a
May be stored in the dive computer 1 and the dive computer 1 may be used to perform a dive simulation.

Also, this diving program 106
The program a can be provided by being recorded in a recording medium such as a magnetic recording medium, an optical recording medium, or a ROM that can be read by the CPU of the PC 100 or the dive computer 1. It is also possible to download such a program to the PC 100 or the dive computer 1 via a network such as the Internet.
