Abstract

PROBLEM TO BE SOLVED: To provide information processing equipment for divers that can record and regenerate diving information in a form corresponding to actual circumstances by judging completion of diving appropriately. SOLUTION: When a diver dives again in a deeper position than the diving completion judgment water depth value 83 before the lapse of diving completion judgment time 84 after rising into a shallower position than the diving completion judgment water depth value 83, it is so judged that one-time diving is continuous. When the diving completion judgment time 84 has elapsed after the diver rises into the shallower position than the diving completion judgment water depth value, it is so judged that the diving is completed, and diving information until the diver finally rises into the shallower position than the diving completion judgment water depth value 83 is recorded as log data of one-time diving. Diving information is regenerated on the basis of this log data.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for divers, also called a dive computer. More specifically, the present invention relates to a technique for recording diving information in such an information processing apparatus.

[0002]

2. Description of the Related Art For a method of calculating decompression conditions after diving performed in a diver's information processing apparatus called a dive computer, see "DIVE COMPUTERS A CONSUMER'S GUIDE TO HISTORY," written by KEN LOYST et al.
THEORY & PERFORMANCE ') Watersport Publishing Inc.
(1991). For literature on the theory, see AA Buhlmann's "Decompression-Deco
mpression Sickness ", Springer, Berlin (1984). Both of these documents suggest that inert gas such as nitrogen in the inhaled air dissolved into the body by diving may become a bubble in the body and cause decompression sickness. Here, from the perspective of more reliably preventing decompression sickness, AA Buhlmann's "Decompression-Decompression
Sickness ", Springer, Berlin (1984), pp.14, is also being studied.

[0003]

(Equation 1)

In this equation, PIig is the partial pressure of the inert gas in the respiratory gas, and k is a constant determined by the half-saturation time.

According to this equation, Pigt (t ₀ ) <P
In the case of Iig, the internal inert gas partial pressure Pigt (t _E ) increases, that is, absorbs the inert gas,
When (t ₀ )> PIig, the inert gas partial pressure Pi in the body
gt (t _E ) will decrease, i.e. exhaust the inert gas.

[0006] That is, the absorption / discharge of the inert gas into the body is determined by the relationship between the partial pressure of the inert gas in the body and the inert gas of the respiratory gas, irrespective of ascent or descent. Therefore, in the information processing apparatus for divers, by grasping the amount of inert gas accumulated in the body from the magnitude relationship, the time required for the amount of inert gas in the body to return to the normal state after the end of diving (inactive gas in the body) Judging from the amount of inert gas accumulated in the body or the current amount of inert gas accumulated in the body, the time during which non-decompression diving can be performed at a certain water depth (non-decompression diving possible time) is obtained, and the diver is notified of this. Can dive under conditions that do not cause decompression sickness.

Also, in the information processing apparatus for divers, it is convenient to be able to reproduce the dive information such as the dive time and the maximum depth of the dive performed this time later, so that the dive information is stored in RAM or the like for each dive. It is configured so that it can be recorded as log data. However, it is inconvenient to use a method in which the diver performs a switch operation every time the diving is completed and diving information is recorded as log data. Therefore, in the conventional information processing apparatus for divers, as shown in FIG. 9 (A), a water depth value for diving end determination is set in advance, and at the time T21 when the surface ascends to a position shallower than the water depth value for diving end determination. Is automatically determined as the end of the dive, and diving information until the end of the dive is automatically recorded as log data for one dive.

[0008]

However, such a configuration as the conventional information processing apparatus for divers, in which the point at which the surface ascends to a position shallower than the water depth value for diving end determination is determined to be the end of diving, is not convenient. There is a problem. That is, in an actual diving, as shown in FIG. 9B, after ascending at a time T22 to a position shallower than the diving end determination water depth, at a time T23,
There are many cases of diving to a position deeper than the dive end determination water depth value.
I thought that it was one dive, but when I played the diving information (log data), the diving information was divided as if I had dived until time T22 and two dives from time T23 to time T24 Played and inconvenient. Further, since the log data that can be recorded in the divers information processing device is generally limited to several times as the number of dives, as in the conventional case, the log data rises to a position shallower than the diving end determination water depth value. There is also the inconvenience that if you treat it as a single dive, you will soon run out of memory.

[0009] In view of the above problems, an object of the present invention is to provide:
An object of the present invention is to provide a diver's information processing apparatus capable of recording and reproducing diving information in a form suitable for actual situations by appropriately determining the end of diving.

[0010]

In order to solve the above problems, according to the present invention, a display section for displaying various information, a water depth measuring means for measuring a water depth, a time measuring means for measuring a lapse of time, and In addition to displaying diving information such as water depth on the display unit, the diving information was recorded in the temporary recording unit, and was recorded in the temporary recording unit every time it was determined that one dive was completed. A divers information processing apparatus having a control unit for recording diving information as log data for diving information reproduction in a log data recording unit, wherein the control unit performs the measurement by the water depth measuring unit and the measurement by the timing unit. Based on the result, after the diver descends to a position deeper than the water depth for dive start determination, when the diver ascends to a position shallower than the water depth for dive end determination, Before elapse again, when diving to a position deeper than the diving end determination water depth value, it is determined that one dive is continuing, and the surface remains at a position shallower than the diving end determination water depth value. It is determined that the dive has ended when the dive end determination time has elapsed, and from the time of diving to a position deeper than the diving end determination depth for the first time in this dive, to a position shallower than the diving end determination depth. The dive information recorded in the temporary recording unit up to the time of the last ascent is recorded as log data for one dive in the log data recording unit.

According to the present invention, the dive end is determined to be a time when the user ascends to a position shallower than the water depth value for judging the end of the dive and when a predetermined time (time for judging the end of the dive) elapses while remaining at such shallow position. Therefore, even if the user descends to a deep position after ascending to a position shallower than the diving end determination water depth value, it is treated as one dive, so that it is not mistakenly treated as a plurality of dives. Therefore, the diving information can be recorded and reproduced in a form suitable for the actual situation, for example, the diving information is not recorded and reproduced in pieces. Further, even when log data can be recorded only for a maximum of 10 dives, for example, memory over does not occur unnecessarily. Furthermore, even if it is possible to record log data only for a maximum of 10 dives, for example, and if it is configured to automatically delete older data when diving more, important log data is inadvertently updated. , Will not be deleted. In addition, since diving information is recorded as log data only for diving where the diver descends to a position deeper than the water depth for diving start determination, it is possible to prevent diving information from being recorded for shallow diving such as diving Can be. Furthermore, not the dive information until the dive end determination time elapses, but the dive information up to the last descent at a position shallower than the dive end determination water depth value is recorded as log data. Useless data is not recorded until the usage time elapses.

[0012] In the present invention, the control means may control the display unit during the dive from when the diver floats to a position shallower than the diving end determination water depth to when the dive end determination time elapses. It is preferable that diving information having the same content as the displayed diving information is continuously displayed on the display unit. This is because during one dive, the diver may rise to a position shallower than the water depth value for diving end determination and then dive deeper again.

[0013] In the present invention, the control means may store the diver in the temporary recording section from when the diver ascends to a position shallower than the diving end determination water depth until the dive end determination time elapses. It is preferable that the dive information is displayed on the display unit. That is, it is convenient if the current dive information can be reproduced and displayed without waiting for the dive information to be determined as log data.

[0014] In the present invention, the control means may be configured to control the time from when the first dive is performed to a position deeper than the diving end determination depth in the current dive to when the dive finally ascends to a position shallower than the diving end determination depth. It is preferable that the dive information recorded in the temporary recording section is recorded as log data in the log data recording section only when the time exceeds the diving determination time. With this configuration, it is possible to prevent a short-time diving such as diving from being recorded, so that memory can be saved.

In the present invention, the water depth for judging the start of diving and the water depth for judging the end of diving may be set to different water depths. The diving start determination depth and the diving end determination depth are set to the same depth from the viewpoint of matching the determination when the dive is started and the reference when initially determining that the dive has started. Is preferred.

In the present invention, furthermore, the ascent rate measuring means for measuring the ascent rate during the ascent based on the measurement result of the water depth measuring means and the measurement result of the timing means, When the current ascent speed is higher than the ascent speed upper limit value by comparing the set ascent speed upper limit value, the ascent speed violation warning means for warning that the ascent rate violation is provided, and the control means is provided. It is preferable that the log data recording unit also records whether or not there has been a rising speed violation during the current dive every time the dive is completed.

In this case, the control means informs the log data recording unit that the ascent of the ascent rate has been violated only when the ascent rate violation warning is issued a plurality of times continuously during the current dive. It is preferable that the information is recorded as log data. This is because, in the case where the rising speed is measured to be higher due to the movement of the arm by the diver and the rising speed is violated, it is not desired to record the rising speed violation as log data.

In the present invention, the control means is configured to display the lapse of time while the dive is paused on the display unit based on the measurement result of the time counting means, and to control the time until boarding an airplane. It is preferable to be configured to help ensure a sufficient time, such as 24 hours, and even 48 hours.

[0019]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[Overall Configuration] FIGS. 1A and 1B are plan views showing a device main body and a part of an arm band of a diver's information processing apparatus according to the present embodiment, respectively. It is a side view at the time of seeing. FIG. 2 is a block diagram thereof.

In FIG. 1, a diver's information processing apparatus 1 of the present embodiment is also called a dive computer, and measures the amount of nitrogen accumulated in the body during diving (partial nitrogen pressure in the body). Based on the results, the display indicates the rest time to be taken on land after diving. In this information processing apparatus 1 for divers, arm bands 3 and 4 are connected to a 6 o'clock side and a 12 o'clock side of a wristwatch, respectively, with respect to a rectangular apparatus main body 2.
4, it can be worn on the wrist and used like a wristwatch. The apparatus main body 2 has an upper case 21 and a lower case 22 which are fixed in a completely watertight state by screws or the like, and a substrate (not shown) on which various electronic components and the like are mounted is housed inside. ing. The power supply of the entire apparatus is a button-type battery (not shown) built in the apparatus main body 2.

A display unit 10 using a liquid crystal display panel 11 is formed on the upper surface side of the apparatus main body 2, and switches A and B composed of two push buttons are formed on the wristwatch at 6 o'clock. I have. Therefore, the switch operation is easy even during diving. The switches A and B are operation units 5 for selecting and switching each mode performed in the diver's information processing apparatus 1 as described later. A water entry monitoring switch 30 (moisture detection sensor) for monitoring whether or not diving has started is configured on the 9 o'clock side of the wristwatch on the upper surface side of the apparatus main body 2. The water entry monitoring switch 30 is provided on the upper surface of the apparatus main body.
It is determined that water has entered when the electrodes 31 and 32 conduct with seawater or the like and the resistance between the electrodes 31 and 32 decreases. However, the water entry monitoring switch 30 is used only to detect that water has been entered and to shift to a diving mode, which will be described later, and does not detect that one tying has been started. That is, the arm on which the information processing apparatus 1 for divers is mounted may be merely immersed in seawater, and in such a case, it should not be treated as having started diving. Therefore, in the information processing apparatus 1 for divers of the present embodiment, the water depth (water pressure) is more than a certain level by the pressure sensor built in the apparatus main body, for example, in this embodiment, the water depth is more than 1.5 m (water depth value for diving start determination). It is assumed that the dive has started when

As shown in FIG. 2, the diver's information processing apparatus 1 of the present embodiment includes a liquid crystal display panel 11 for displaying various kinds of information to notify the user, and a liquid crystal driver 12 for driving the same. A display unit 10 and a control unit 50 (control means) that performs processing in each mode and causes the liquid crystal display panel 11 to perform display according to each mode are configured. For the control unit 50, a switch A,
B, an output from the water input monitoring switch 30, and the like are input.

The diver's information processing apparatus 1 displays the normal time and measures the dive time.
, A clock output from the oscillation circuit 31 is input via the frequency dividing circuit 32, and the time counter 33 constitutes a time measuring means 68 in which time is measured in units of one second.

The diver's information processing apparatus 1 measures and displays the water depth, and also measures the amount of nitrogen gas (inert gas) accumulated in the body from the water depth (water pressure) and the dive time. , A pressure sensor 34 (semiconductor pressure sensor), an amplifier circuit 35 for an output signal of the pressure sensor 34, and an A / D which converts an analog signal output from the amplifier circuit 35 into a digital signal and outputs the digital signal to the control unit 50. A water depth measurement unit 61 including the conversion circuit 36 is configured. Further, the information processing device 1 for divers is provided with a sound notification device 37 and a vibration generating device 38, which can issue a warning to the diver with an alarm sound or vibration.

In this embodiment, the control unit 50 includes a CPU 51 for controlling the entire apparatus, a control circuit 52 for controlling the liquid crystal driver 12 and the time counter 33 under the control of the CPU 51, a ROM 53, and a RAM 54. Each mode, which is configured and executed by the CPU 51 based on a program stored in the ROM 53, realizes each mode described later. The RAM 54 is used as a memory for temporarily recording various data (diving information) obtained during diving and a memory for recording log data for reproducing diving information in a log mode described later.

[Explanation of Display Unit] Referring again to FIG. 1A, the display surface of the liquid crystal display panel 11 has eight display areas. Of these eight display areas, a first display area 111 located on the 12 o'clock side of the wristwatch is the largest of the display areas, and includes a diving mode, a surface mode (time mode) described later. ), The planning mode, and the log mode, the current water depth, the current month, the water depth rank, and the diving month (log number) are displayed. The second display area 112 located on the 3 o'clock side of the first display area 111 has a dive time, a current time, and a no decompression time in a diving mode, a surface mode (time mode), a planning mode, and a log mode, respectively. Dive time, dive start time (dive time)
Is displayed. The third display area 113 located on the 6 o'clock side of the first display area 111 includes a diving mode,
In the surface mode (time mode), planning mode, and log mode, the maximum water depth, body nitrogen discharge time, safety level, and maximum water depth (average water depth) are displayed. A fourth display area 114 located on the 3 o'clock side of the third display area 113 has a no-decompression diving time and a water surface stop in the diving mode, the surface mode (time mode), the planning mode, and the log mode, respectively. The time, temperature and diving end time (maximum water temperature at depth) are displayed. In the fifth display area 115 located on the 6 o'clock side of the third display area 113, the power supply exhaustion warning 104 and the high rank 103 are displayed. In the sixth display area 116 located at the 6 o'clock side of the liquid crystal display panel 11, the amount of nitrogen stored in the body is graphically displayed. Further, a seventh display area 117 located on the 3 o'clock side of the sixth display area 116.
There is an area that indicates whether nitrogen (inert gas) tends to be absorbed or discharged when the decompression diving condition is reached in the diving mode, and one of the ascent speed violation warnings that the ascent speed is too high Area to display "SLOW" as a warning, and "DE" as a warning that the decompression diving has been reached during the dive
The area | region which displays "CO" is comprised.

As described above, on the display surface of the liquid crystal display panel 11, the area for displaying the current water depth (the first display area 111) in the diving mode is the largest, so that the diver can use important data. It is easy to see the display of the current water depth. Moreover, since the display surface of the liquid crystal display panel 11 is recessed from the upper surface of the upper case 21, even if there is a step due to the upper case 21 around the display surface of the liquid crystal display panel 11, the current water depth in the diving mode is not affected. Since the display area (first display area 111) is arranged on the 12 o'clock side, the display of the current water depth is not hidden by the step. Therefore, also from this point, in the information processing apparatus 1 of the present embodiment, it is easy to visually recognize the display of the current water depth, which is important data.

[Structure of Safety Information Deriving Means] FIG. 3 shows the calculation of the amount of nitrogen stored in the body (the amount of inert gas stored in the body) in the diver's information processing apparatus 1 according to the present embodiment. It is a functional block diagram of safety information deriving means which derives safety information such as time and no-decompression diving time.

In FIG. 3, the information processing device 1 for divers absorbs nitrogen contained in the intake air into the body, and
A safety information deriving means 60 that simulates the state of excretion and calculates the amount of nitrogen in the body (partial nitrogen pressure in the body) is configured. The safety information deriving means 60 determines the amount of nitrogen at a certain water depth based on the amount of nitrogen in the body. Time for no-decompression diving (no-decompression diving time) and how long the excess nitrogen dissolved in the body during previous dives is released above the water surface (internal body nitrogen removal time / inert gas in the body) (Discharge time) is derived as safety information for a diver to safely dive. The calculation of the amount of nitrogen in the body described below is merely an example, and various methods can be used. Therefore, an example thereof will be briefly described here.

The safety information deriving means 60 first uses a pressure sensor 34, an amplification circuit 35, and an A / D conversion circuit 36 shown in FIG. 61, the CPU 51 shown in FIG.
ROM 53, RAM 54, a respiratory nitrogen partial pressure calculating means 62 realized as a function, a respiratory nitrogen partial pressure storing means 63 using the RAM 54 shown in FIG. 2, a CPU shown in FIG.
51, a ROM 53 and a RAM 54 for calculating the partial pressure of nitrogen in the body realized as functions of the RAM 54, a means for storing a partial pressure of nitrogen in the body 65 using the RAM 54 shown in FIG. 2, and a clocking means using the time counter 33 shown in FIG. 68, comparing means 6 implemented as functions of the CPU 51, the ROM 53, and the RAM 54 shown in FIG. 2 and comparing data stored in the respiratory nitrogen partial pressure storing means 63 and the internal nitrogen partial pressure storing means 65.
6, CPU 51, ROM 53, RAM 54 shown in FIG.
The half-saturation time selecting means 67 realized as the function of (1) is constituted.

Of these components, the respiratory nitrogen partial pressure calculating means 62, the internal nitrogen partial pressure calculating means 64, and the comparing means 6
6. The half-saturation time selecting means 67 is the CPU 51, R
Although it can be realized as software by the OM 53 and the RAM 54, it can also be realized by only a logic circuit which is hardware, or a combination of a logic circuit and a processing circuit including a CPU and software.

In this configuration example, the water depth measuring means 61 measures and outputs a water pressure P (t) corresponding to time t.

The respiratory nitrogen partial pressure calculating means 62 calculates and outputs the respiratory nitrogen partial pressure PIN ₂ (t) based on the water pressure P (t) output from the water depth measuring means 61. The respiratory nitrogen partial pressure PIN ₂ (t) can be calculated by the following equation PIN ₂ (t) = 0.79 × P [bar] from the water pressure P (t) during diving.

The respiratory nitrogen partial pressure storage means 63 stores the P calculated by the respiratory nitrogen partial pressure calculating means 62 as
The value of IN ₂ (t) is stored.

The internal nitrogen partial pressure calculating means 64 calculates the internal nitrogen partial pressure PGT for each tissue having different nitrogen absorption / extraction rates.
Calculate (t). Taking one tissue as an example, the internal nitrogen partial pressure PGT (t _E ) absorbed / exhausted from dive time t = t ₀ to t _E is the internal nitrogen partial pressure PGT at t _{0.
(T 0)} and the dive time _{t E,} is calculated from the half-saturation time _{T H.}

[0037] In the half-saturation time _{T H} referred herein, as shown in FIG. 4, tissue nitrogen partial pressure PGT _{(t E)} is under the water pressure from _{t 0} o'clock tissue nitrogen partial pressure PGT _{(t 0)} In the process of reaching the respiratory nitrogen partial pressure PIIG, the internal nitrogen partial pressure P
This corresponds to a time (half time) required to reach an intermediate pressure value between GT (t ₀ ) and the respiratory nitrogen partial pressure PIIG.

Then, as shown in FIG.
It is stored in the internal body nitrogen partial pressure storage means 65 as PGT (t _E ). The calculation formula for that is as follows.

[0039]

(Equation 2)

Here, k is a constant obtained experimentally.

Next, the comparison means 66 compares PIN ₂ (t), which is the result of the respiratory nitrogen partial pressure storage means 63, with PGT (t), which is the result of the internal nitrogen partial pressure means 5, and as a result, by the half-saturation time selecting means 67, and variable half saturation time T _H as used tissue nitrogen partial pressure calculation unit 64.

For example, the respiratory nitrogen partial pressure PIN ₂ (t ₀ ) at the time t = t ₀ , the internal nitrogen partial pressure PGT (t ₀ )
Are stored in the respiratory nitrogen partial pressure storage means 63 and the internal nitrogen partial pressure storage means 65, respectively.
6 compares this PIN ₂ (t ₀ ) with PGT (t ₀ ).

The internal nitrogen partial pressure calculating means 64 is controlled by the half-saturation time selecting means 67 as follows.
= Tissue nitrogen partial pressure PGT at the time of _{t E (t E)} is calculated.

[0044]

(Equation 3)

[0045]

(Equation 4)

In the above two equations, k is a constant, T _H2 <T _H1
Is calculated.

It should be noted that PGT (t ₀ ) = PIN ₂ (t
₀ ), the half-saturation time _TH = ( _TH2 + _TH1 )
It is preferable to calculate as / 2. Further, these times (measurement for t ₀ and t _E ) are managed by the timer means 68 of FIG.

Here, PGT (t ₀ )> PIN
_{When 2} (t ₀ ), nitrogen is excreted from the body, and when PGT (t ₀ ) <PIN ₂ (t ₀ ), nitrogen is absorbed into the body. Changing the half-saturation time at these times means that when nitrogen is discharged, the half-saturation time is long and it takes time to discharge, and conversely, when nitrogen is absorbed, the half-saturation time is It is short and the time required for absorption is short compared to the time required for discharge. In this way, the simulation of the amount of nitrogen in the body can be performed more strictly. Therefore, if an allowable value of the internal nitrogen partial pressure is set, the time required to reach this allowable value at a certain water depth (water pressure) (no decompression diving time / safety information) and the internal nitrogen partial pressure on the water surface The time until the value decreases to the equilibrium value (internal nitrogen excretion time / safety information) can be determined with high accuracy. In this manner, the diver's information processing apparatus 1 of the present embodiment includes the dive available time deriving means 92 and the in vivo nitrogen exhausting time deriving means 91 which derive the non-decompression diving available time and the internal nitrogen exhausting time as diver safety information. Have been.

[Configuration for Determining Start / End of Diving] The diver's information processing apparatus 1 measures the depth of water, the temperature of water, the measurement of diving time, the amount of nitrogen accumulated in the body during diving. Measurement of the accumulation amount, measurement of the diver's flying speed, and the like are performed, and display and warning are performed based on the measurement results. At the end of the dive, diving information such as these measurement results and the presence or absence of a warning is recorded as log data, and is reproduced in a log mode described later. The recording operation of the diving information is performed by the time measuring means 68 and the water depth measuring means 6 shown in FIG.
1. This is performed by using a part of the functions of the water entry monitoring switch 30 and the control unit 50 (the functions of the CPU 51, the ROM 53, the RAM 54, etc.).

That is, as shown in FIG. 5, in the information processing apparatus 1 for divers, the water depth measuring means 61 shown in FIG.
Both the output of the time keeping means 68 and the output of the water entry monitoring switch 30 are input to the control unit 50. The control unit 50 includes a diving start / end determining means 81 and a diving information recording means 85 using the RAM 54 as a memory. It is configured.
These configurations will be described in detail below with reference to FIG.

The dive start / end determining means 81 determines whether the dive is started at time T1.
1. Water entry monitoring switch 3 indicates that the diver has entered the water
After 0 is detected, it is determined that the dive has started when the dive is deeper than the 1.5 m water depth value set as the dive start determination water depth value 82 at time T12.
As a result, measurement of the diving time is started. The dive time, average water depth, dive start time,
Diving information such as the amount of nitrogen in the body during diving, maximum water depth, dive time, water temperature at maximum water depth, diving date and time, and altitude rank are updated by the diving information recording means 85 during diving as necessary. While being recorded, it is recorded in a temporary recording area 86 (temporary recording unit) configured in the RAM 54.

After the dive is started, the dive start / end determination means 81 determines the time T13 based on the measurement result of the water depth measurement means 61 and the measurement result of the time measurement means 68.
Is set as a water depth value 83 for diving end determination in
Even if a diver rises to a position shallower than the water depth of 5m,
If 10 minutes set as the diving end determination time 84 has not elapsed, it is not determined that one dive has ended. For this reason, the dive start / end determination means 81
Means that even if the diver ascends at a position shallower than the water depth of 1.5 m (water depth value for diving end determination 82) at time T13, 1
Before 0 minutes (dive end determination time 84) elapses,
When diving to a position deeper than the water depth value of 1.5 m (water depth value for dive termination determination 82) at time T14, it is determined that one dive is continuing.

That is, the dive start / end determination means 81
Means that at time T15, the diver floats at a position shallower than the water depth value of 1.5 m (water depth value 83 for diving end determination), and
It is determined that the diving has ended only when 10 minutes (the dive end determination time 84) has elapsed at time T16. Then, the dive information recording unit 85 starts the dive end determination water depth value 8 at the time of the first dive (time T12) at a position deeper than the dive start determination water depth value 82 in this dive.
The dive information recorded in the temporary recording unit 86 up to the time of the last ascent to a position shallower than 3 (time T15) is determined as log data for one dive, and is stored in the log data recording area 87 configured in the RAM 54. Record with a log number. Therefore, the log data recording area 87
If the log data recorded in the dive is used, the dive from time T12 (diving start time) to time T15 (diving end time) is regarded as one dive even in the diving shown in FIG. Can be displayed and reproduced on the liquid crystal display panel 11 of the display unit 10 later.

Here, while diving, the liquid crystal display panel 11 displays diving information required for diving, such as the current water depth, diving time, maximum water depth, no-decompression diving time, nitrogen graph in the body, and altitude rank. In this embodiment,
The diver floats at a position shallower than a water depth value of 1.5 m (water depth value 83 for judging the end of diving), and the liquid crystal display panel 11 keeps the diver up to 10 minutes (time 84 for judging the dive end). Diving information continues to be displayed. As described above, even if the diver ascends to a position shallower than the water depth value of 1.5 m (water depth value for diving end determination 82) at time T13, before 10 minutes (time 84 for diving end determination) elapses. This is because, at the time T14, when diving to a position deeper than the water depth value of 1.5 m (water depth value 82 for judging completion of diving), it is regarded that one dive is continued. Furthermore, a water depth value of 1.5 m (water depth value 83 for diving end determination)
The diver floats at a position shallower than the diver, and after 10 minutes (time 84 for determining the end of diving) has elapsed, the liquid crystal display panel is maintained until the diver rises above the water surface and the electrodes 31, 32 return to the insulated state. At 11, the above information is continuously displayed. That is, after the water entry monitoring switch 30 detects that the electrodes 31 and 32 conduct when the diver enters the water, the diver rises above the water surface and the electrodes 31 and 32 of the water entry monitoring switch 30 return to the insulated state. Until then, the same information is continuously displayed on the liquid crystal display panel 11 as the diving mode.

In the present embodiment, 10 minutes (time 84 for diving end determination) at time T16 after the diver finally ascended to a position shallower than 1.5 m (water depth value 83 for diving end determination) at time T15. Until the elapse, the diving information recorded in the temporary recording section 86 can be displayed on the liquid crystal display panel 11 of the display section 10 by operating a predetermined switch. Therefore, even before the dive information is determined as log data in the current dive, the dive information of the current dive can be reproduced and displayed, which is convenient.

As described above, according to the diver's information processing apparatus 1 of the present embodiment, even if the user descends to a deep position after ascending to a shallow position, it is treated as one dive and erroneously treated as a plurality of dives. Will not be heard. Therefore, the diving information can be recorded and reproduced in a form suitable for the actual situation, such that the diving information is not recorded and reproduced in pieces. Moreover, it is possible to prevent unnecessary diving information such as diving from being recorded in the log data recording area 87.

Here, since log data can be recorded in the log data recording area 87 only for a maximum of, for example, 10 dives, when diving is performed further, the oldest data is automatically deleted in descending order. Even with such a configuration, in the present embodiment, even if the user descends to a deep position after ascending to a shallow position, it is treated as only one dive, so important log data is inadvertently updated and deleted. Never.

The diving start / end determining means 81 determines that the diver has entered the water at time T11 by using the electrodes 31, 3
After the water entry monitoring switch 30 detects that the electric current 2 is conducted, the dive is deeper than the 1.5 m water depth value (dive start determination water depth value 82) at time T12, and then at time T15, the 1.5 m water depth value (dive). If the time until the last ascent to a position shallower than the end determination water depth 83) is within 3 minutes which is preset as the dive determination time 88, that is, the diving has not been performed for 3 minutes or more. In such a case, it is assumed that the dive is of the order of a dive, and the dive information of the diving performed this time is not recorded in the log data recording area 87 as log data. For this reason, unnecessary diving information is not recorded in the log data recording area 87, so that log data can be recorded in the log data recording area 87 only for a maximum of 10 dives. Even when the log data is automatically deleted, important log data is not inadvertently updated or deleted.

[Floating Speed Monitoring Function] The diver's information processing device 1 is configured to monitor the diver's rising speed during a diving mode described later.
The following configuration is realized by using the functions of the U51, the ROM 53, the RAM 54, and the like.

That is, as shown in FIG. 5, in the diver's information processing apparatus 1, the levitation speed measurement for measuring the levitation speed at the time of surfacing based on the measurement result of the above-mentioned clocking means 68 and the measurement result of the water depth measurement means 61. The means 75 compares the measurement result of the ascent rate measuring means 75 with a preset ascent rate upper limit value 76, and if the current ascent rate is higher than the ascent rate upper limit value 76, issues a warning that the ascent rate is violated. And a flying speed violation warning means 77 to be performed. The ascent rate measuring means 75 includes the CPU 51 and the ROM 5 shown in FIG.
3. While being realized as an arithmetic function of the RAM 54, the rising speed violation warning means 77 is provided by the CPU 51, R shown in FIG.
OM 53, RAM 54, sound generator 37, vibration generator 3
8. It is realized as a function such as display on the liquid crystal display panel 11.

In this embodiment, the rising speed violation warning means 7
7 compares the current ascent rate with the current ascent rate for each of the water depth ranges stored in the ROM 53 as the ascent rate value 76, and determines whether the current ascent rate corresponds to the current ascent rate. When the speed is faster than 76, the display on the liquid crystal display panel 11 and the generation of an alarm sound from the alarm device 37 are performed.
Further, a warning of the rising speed violation is issued by a method such as transmission of vibration from the vibration generator 38 to the diver, and the warning of the rising speed violation is stopped when the rising speed returns to the state lower than the rising speed upper limit value 76. In the present embodiment, the following values are used as the above-mentioned ascending speed upper limit value 76 for each water depth range. Current measured water depth value Ascending speed upper limit value less than 1.8 m No warning 1.8 m to 5.9 m 8 m / min (approx. 8 m / 6 sec) 6.0 m to 17.9 m 12 m / min (about 1.2 m / 6 sec) 18.0 m or more 16 m / min (about 1.6 m / 6 sec) is set. That is, where the water depth is deep,
This is because even if the ascent is performed at the same ascent speed, the water pressure ratio before and after ascent per unit time is small, so that even if a relatively high ascent speed is allowed, decompression sickness can be sufficiently prevented. On the other hand, in a place where the water depth is shallow, the water pressure ratio before and after the ascent per unit time is large even when ascending at the same ascent speed, so that only a relatively small ascent speed is allowed.

In this embodiment, a depth value per 6 seconds is stored in the ROM 53 as the upper limit value of the rising speed. this is,
As shown in FIG. 7, the measurement of the water depth is performed every second, but in order to prevent the movement of the arm wearing the information processing device 1 for divers from affecting the ascent speed, the ascent speed measurement is performed for six seconds. The difference between the current water depth measurement value and the previous water depth measurement value six seconds ago is calculated, and the difference is regarded as the floating speed, and the above floating speed upper limit value (m / 6 seconds) Is compared with

In the information processing apparatus 1 for divers of the present embodiment, diving information (various data such as diving date, diving time, maximum depth) is stored and held in the log data recording area 87 of the RAM 54. Diving information recording means 85
The dive information recording unit 85 also records in the log data recording area 87 as log data whether or not a warning has been issued from the ascent speed violation warning unit 77. Accordingly, whether or not the ascent of the ascent speed has occurred during the current dive is reproduced and displayed on the liquid crystal display panel 11 later. However, the diving information recording means 85 determines that a rising speed violation has occurred only when a warning is issued two or more times continuously during one dive.
Record in 7. Therefore, in a case where the ascent speed is erroneously measured high due to the movement of the arm of the diver, the fact that the ascent of the ascent is violated is not recorded as log data.

In the information processing apparatus 1 for divers of the present embodiment, it is assumed that the diving is performed for the first time when the state where the water depth is deeper than 1.5 m continues for 3 minutes or more.
When the surface rises to a position where the water depth is shallower than 1.5 m, the water depth is regarded as 0 m, and the indication is 0 m.
Therefore, if the rising speed violation warning means 77 issues a rising speed violation warning even in such a shallow place as in a deep place, the arm moves several centimeters where the water depth is slightly deeper than 1.5 m, and the water depth becomes lower. If it is considered to be 0m, even slightly shallower than 1.5m,
An ascent rate warning will be issued. as a result,
Divers question the reliability of ascent speed warnings. However, in this embodiment, the current water depth is a predetermined value (1.5
If it is shallower than m), no warning of the violation of the ascent speed is issued regardless of the ascent speed. Therefore, since the above-mentioned unnatural warning is not issued, the confidence in the warning can be increased. That is, as shown in FIG. 7, for example, the previously measured water depth during the ascent is 1.8 m, and ascended from this position as indicated by the solid line L11, the current water depth measured after 6 seconds elapses is 1.5 m. If it is shallower than the (dive end determination water depth value), no warning that the ascent of the ascent is violated is issued.

[Measurement function of water surface pause time]
During diving, excessive nitrogen accumulates in the diver's body, so rapid ascent causes nitrogen in the body to form bubbles and causes decompression sickness. Similarly, after diving, if you board an airplane and move to a high place with excess nitrogen accumulated in your body, the air pressure will drop sharply. May cause.
Therefore, after the dive ends, the airplane should be boarded after 24 hours, preferably 48 hours. Therefore, as shown in FIG. 5, in the diver's information processing apparatus 1 of the present embodiment, the elapsed time from the end of the dive is determined based on the measurement result of the water depth measurement unit 61 and the measurement result of the timer unit 68. Water surface stop time measuring means 89 for measuring time is constituted. That is, the water surface stop time measuring means 89 sets the elapsed time from when the diving start / end determining means 81 determines that the dive has ended based on the measurement result of the water depth measuring means 61 and the measurement result of the timer means 68 as the water surface stop time. measure.

Therefore, after the dive is completed, if the water surface pause time obtained by the water surface pause time measuring means 89 is displayed on the liquid crystal display panel 11, a sufficient pause time is provided to the diver to discharge excess nitrogen from the body. After that, you can be warned to board the plane.

[Explanation of Each Mode] The diver's information processing apparatus 1 configured as described above has the following modes (time mode ST1, surface mode ST2, planning mode ST3, setting mode ST) described below with reference to FIG.
4, used in diving mode ST5, log mode ST6).

(Time Mode ST1) Time Mode ST1
Is a function to be carried on land when no switch operation is performed and nitrogen in the body is in an equilibrium state. The liquid crystal display panel 11 has a current date 100, a current time 101, and an altitude rank 103 (see FIG. 1). ./No mark is displayed when the altitude rank is rank 0.). The altitude rank 103 automatically measures the altitude of the current location and displays the altitude at three ranks. The display of the current time 101 is indicated by the blinking of the colon and the current time 1
01 is notified. For example, in the state shown in FIG. 8, it is displayed that it is 10:06 on December 5 at present.

Also, the air pressure changes when going up and down high and low places above sea level, so that nitrogen dissolves into the body and nitrogen is discharged regardless of the presence or absence of diving in the past. Therefore, in the diver's information processing apparatus 1 of the present embodiment, even in the time mode ST1, when such an altitude change occurs, the decompression calculation is automatically started, and the display changes. That is, although not shown, the time after the altitude changes, the time until the body nitrogen reaches an equilibrium state, and the amount of nitrogen discharged or dissolved from the present time to the equilibrium state are displayed.

In the time mode ST1, when the switch A is pressed, the mode shifts directly to the planning mode ST3, and when the switch B is pressed, the mode shifts directly to the log mode ST6. When the switch B is pressed for 5 seconds while the switch A is pressed after the switch A is pressed, the mode shifts to the setting mode ST4.

During this time mode ST1, FIGS.
When it is detected that water has entered through the water entry monitoring switch 30 shown in (1), a function check is automatically performed. If it is confirmed that the sensors and the like are normal, the operation automatically shifts to the diving mode ST5. At this time, if there is an abnormality in the sensor or the like, the sound notification device 3 shown in FIG.
Notify by alarm sound from 7.

(Surface Mode ST2) The diving information processing apparatus 1 automatically shifts to the surface mode ST2 when the conducting water entry monitoring switch 30 becomes insulated after the end of the dive. The surface mode ST2 is a function for carrying on the land until 48 hours have passed since the last dive. In the surface mode ST2, in addition to the data (current month and day 100, current time 101, altitude rank) displayed in the time mode ST1, an indication of a change in the amount of nitrogen in the body after the end of the dive is displayed. That is, the time until the excess nitrogen dissolved in the body is exhausted and the state of equilibrium is reached is displayed as the body nitrogen exhausting time 201. This body nitrogen excretion time 201
Counts down the time to equilibrium.
After the internal nitrogen excretion time 201 becomes 0 hour and 00 minutes, there is no display. Further, the elapsed time after diving is displayed as the water surface pause time 202, and the water surface pause time 202
In the diving mode ST5, the time at which the surface finally rises to a position where the water depth is shallower than 1.5 m is started as the end of the diving, and the time is counted up to 48 hours, and then no display is made. Accordingly, the information processing apparatus 1 for divers enters the surface mode ST2 on land until the end of 48 hours after the end of the diving, and thereafter the time mode ST1. In the state shown in FIG. 8, it is displayed that the current time is 11:58 on December 5, and that 1 hour and 13 minutes have passed since the end of the dive. In addition, it is displayed that the amount of nitrogen dissolved in the body by the diving performed so far corresponds to four nitrogen graphs 203 in the body, and the time from this state until excess nitrogen in the body is exhausted to reach an equilibrium state. It is displayed that (body nitrogen excretion time 201) is, for example, 10 hours and 55 minutes.

In the surface mode ST2, pressing the switch A directly shifts to the planning mode ST3, and pressing the switch B shifts directly to the log mode ST6. When the switch B is pressed for 5 seconds while the switch A is pressed after the switch A is pressed, the setting mode S
Move to T4.

During the surface mode ST2, when it is detected that water has entered through the water entry monitoring switch 30, a function check is automatically performed. If it is confirmed that the sensors and the like are normal, the diving mode ST5 is automatically set. Move to At this time, when there is an abnormality in the sensor or the like, the fact is notified by an alarm sound from the sound notification device 37 or the like.

(Setting Mode ST4) Setting Mode ST4
Is a function for setting ON / OFF of a warning alarm and setting of a safety level in addition to the setting of the date 100 and the current time 101. In this setting mode ST4,
The current month and day 100, year 106, current time 101, safety level (not shown), alarm ON / OFF (not shown), and altitude rank are displayed. Of these items, the safety level is usually And a level for performing a decompression calculation on the premise of moving to a place at an altitude rank one rank higher after diving. The ON / OFF of the alarm is a setting for setting whether or not to sound various warning alarms from the alarm device 37. If the alarm is set to OFF, the alarm does not sound. Therefore, in a device such as the diver's information processing device 1 in which running out of battery is particularly fatal, the power consumed for an alarm can be reduced, which is convenient.

In this setting mode ST4, every time the switch A is pressed, the setting items are switched in the order of hour, second, minute, year, month, day, safety level, alarm ON / OFF, and the display of the corresponding portion blinks. I do. At this time, when the switch B is pressed, the numerical value or character of the setting item changes, and when the switch B is continuously pressed, the numerical value or character changes quickly. Alarm ON / O
When the switch A is pressed while the FF is blinking, the mode returns to the surface mode ST2 or the time mode ST1. If neither of the switches A and B is pressed for one to two minutes, the surface mode ST2 or the time mode ST
Return to 1 automatically.

During the setting mode ST4, a function check is automatically performed also when it is detected that water has entered through the water entry monitoring switch 30, and if it is confirmed that the sensors and the like are normal, the operation proceeds to the diving mode ST5. Migrate automatically. At this time, when there is an abnormality in the sensor or the like, the fact is notified by an alarm sound from the sound notification device 37 or the like.

(Planning mode ST3) The planning mode ST3 is a mode for inputting the maximum water depth and dive time guide for the next dive. In this mode, the water depth rank 301, the non-decompression diving time 30
2. Safety level, altitude rank, water downtime 20
2. The body nitrogen graph 203 is displayed. Water depth rank 3
The display of the rank 01 is sequentially changed from a low rank to a high rank, and the non-decompression diving time 302 at each water depth rank 301 is displayed. For example, the water depth rank 301 is 9m, 12m, 15m, 18m, 21
m, 24m, 27m, 30m, 33m, 36m, 39
m, 42 m, 45 m, and 48 m in this order every 5 seconds. At this time, if the mode has shifted from the time mode ST1 to the planning mode ST3, the plan is an initial diving without excessive nitrogen accumulation in the body due to past diving.
When the in-vivo nitrogen graph 203 is 0 and the water depth is 15 m, the no-decompression diving time 302 is displayed as 66 minutes. Therefore, it can be seen that non-decompression diving is possible at a depth of 12 m or more and 15 m or less and less than 66 minutes. On the other hand, if the mode has shifted from the surface mode ST2 to the planning mode ST3, since the plan is a repetitive diving having excessive nitrogen accumulation in the body due to past diving, the in-vivo nitrogen graph 203 is equivalent to four, and Maximum water depth is 15m
In this case, the non-decompression diving time 302 is displayed as 49 minutes. Therefore, it can be understood that non-decompression diving is possible at a depth of 12 m or more and 15 m or less and less than 49 minutes.

In the planning mode ST3, if the switch A is kept pressed for 2 seconds or more before the water depth rank 301 is displayed as 48 m, the mode directly shifts to the surface mode ST2. After the depth rank 301 is displayed as 48 m, the mode automatically shifts to the time mode ST1 or the surface mode ST2. Further, when there is no switch operation for a predetermined period, the mode automatically shifts to the surface mode ST2 or the time mode ST1, so that it is convenient because there is no need to perform the switch operation each time. On the other hand, when the switch B is pressed, the mode directly shifts to the log mode ST6.

During the planning mode ST3,
When it is detected that water has entered through the water entry monitoring switch 30, a function check is automatically performed, and if it can be confirmed that the sensors and the like are normal, the diving mode ST5
Automatically transition to. At this time, when there is an abnormality in the sensor or the like, the fact is notified by an alarm sound from the sound notification device 37 or the like.

(Diving Mode ST5) The diving mode ST5 is a mode at the time of diving. In the non-decompression diving mode ST51, the current water depth 501, diving time 502,
This function displays information necessary for diving, such as the maximum water depth 503, the no-decompression diving time 302, the in-vivo nitrogen graph 203, and the altitude rank. For example, in the state shown in FIG. 8, it is displayed that 12 minutes have elapsed since the start of the diving, the water depth is 16.8 m, and at this water depth, non-decompression diving can be continued for another 42 minutes. .
In addition, it is displayed that the maximum water depth up to the present is 20.0 m.
Indicates that the level is a level in which four marks are lit.

Here, for the purpose of notifying the diver that the mode has shifted to the diving mode ST5, the display of the current water depth 501 may be blinked. With this configuration,
Since the fact that the processing in the diving mode ST5 is being performed can be visually recognized on the display on the liquid crystal display panel 11, the diver does not need to worry about whether or not the diving mode ST5 is functioning normally, which is convenient. .

In the diving mode ST5, as described above, a rapid ascent causes a decompression sickness, as described above, so that the current ascent speed is obtained every 6 seconds and the current ascent speed and the current water depth are determined. The ascent rate is compared with the corresponding ascent rate, and if the ascent rate obtained this time is faster than the ascent rate, an alarm sound (floating speed violation warning) is emitted from the sounding device 37 at a frequency of 4 kHz for 3 seconds. LCD panel 1 so as to reduce the floating speed
At 1, the display of "SLOW" and the display of the current water depth are alternately blinked at a cycle of 1 Hz, and a rising speed violation warning is issued. When the ascent speed is reduced to a normal level, the ascent speed warning is stopped.

In the diving mode ST5, when the switch A is pressed, the current time 101 and the current water temperature 504 are displayed in the current time display mode ST52 only while the switch A is kept pressed. In the state shown in FIG. 8, it is displayed that the current time is 10:18 and the water temperature is 23 ° C. Thus, the diving mode ST5
When there is a switch operation to that effect, the current time 101 and the current water temperature are displayed only for a predetermined period,
Even if only the data necessary for diving is always displayed on the small display surface (non-decompression diving mode ST51), the current time 101 can be displayed as needed (current time display mode ST52). It is convenient. Moreover, even in the diving mode ST5, the switch operation is used for switching the display, so that information desired by the diver can be displayed at an appropriate timing.

During the dive mode ST5, when the water surface rises to a position shallower than 1.5 m, the diving is regarded as being completed, and when the conducting water entry monitoring switch 30 becomes insulated. The mode automatically shifts to the surface mode ST2. During this time, the diving information recording means 78 shown in FIG. 3 treats the dive information from the time when the water depth becomes 1.5 m or less to the last time when the water depth becomes 1.5 m or less as one dive (the date of the dive). Various data such as dive time and maximum water depth) are stored and retained in the dive information recording means 78 (RAM 54). At the same time, if the ascent rate warning is given twice or more consecutively during the current dive, that fact is also recorded as diving information.

The information processing apparatus 1 for divers of the present embodiment
Although the configuration is based on non-decompression diving, if a decompression diving condition occurs, the diver is notified with an alarm sound to that effect, and the mode is switched to the following decompression diving display mode ST53. That is, in the decompression diving display mode ST53, the current water depth 501, the dive time 502, the body nitrogen graph 203, the altitude rank, the decompression stop depth 505, the decompression stop time 506, and the total ascent time 50
7 is displayed. In the state shown in FIG.
It is displayed that four minutes have passed and the water depth is 29.5 m. In addition, since the amount of nitrogen in the body exceeds the maximum allowable value and is dangerous, the water depth is 3m while keeping the safe ascent speed.
Is displayed, and an instruction to stop decompression for 1 minute is displayed. Further, an instruction is displayed that a safe ascent speed should take at least 5 minutes to reach the water surface. Further, the fact that the amount of nitrogen in the body is currently increasing is displayed by an upward arrow 508. Then, the diver floats after stopping the decompression based on the above display contents. During the decompression, the downward arrow 509 indicates that the amount of nitrogen in the body is on the decrease.

(Log mode ST6) When the switch B is pressed in the time mode ST1 or the surface mode ST2, the mode directly shifts to the log mode ST6. Log mode S
At T6, as described above, the diving information recording means 85 stores in the log data recording area 87 various diving information when diving for more than 3 minutes or more than 1.5 m in the diving mode ST5. It is a function to display and play things. Such diving data is sequentially stored as log data for each dive, and up to 10 log data are stored and retained, and when diving more, older data is deleted in order from the oldest, and the latest 10 dive data are always stored. Dives are remembered.

In the log mode ST6, the log data is displayed on two screens switched every four seconds. First
In the screen ST61, the dive date 601 and the average water depth 50
9. The dive start time 603, the dive end time 604, the altitude rank, and the in-vivo nitrogen graph 203 when the dive ends are displayed. On the second screen ST62, a log number 605, which is a dive number on that day, a maximum water depth 608, a dive time 606, a water temperature 607 at the maximum water depth, an altitude rank,
A graph 203 of the in-vivo nitrogen when the diving is completed is displayed. For example, in the state shown in FIG. 8, when the altitude rank is 0, the second dive on December 5 is dive 1
After starting at 0:07, it ends at 10:45,
It is displayed that the dive was for 38 minutes. In the diving at this time, the average water depth was 14.6 m, the maximum water depth was 26.0 m, and the water temperature at the maximum water depth was 23 ° C. After the dive was completed, the nitrogen in the in-vivo nitrogen graph 203 dissolved into the body for four times. Is displayed. As described above, in the log mode ST6, various information is displayed while automatically switching between the two screens, so that a large amount of information can be displayed even if the display surface is small.

In the log mode ST6, if the speed violation warning is given twice or more during the diving displayed this time, the fact is notified, for example, by the liquid crystal display panel 11.
In the seventh display area 117, “SLOW” is displayed.

In the log mode ST6, each time the switch B is pressed, the data is switched from new data to old data, and after the oldest data is displayed, the mode shifts to the time mode ST1 or the surface mode ST2. If the switch B is kept pressed for 2 seconds or more during the operation, the mode shifts to the time mode ST1 or the surface mode ST2. Furthermore, even when neither of the switches A and B is pressed for 1 to 2 minutes, the mode automatically returns to the surface mode ST2 or the time mode ST1, so that it is convenient because there is no need to perform the switch operation each time. On the other hand, when the switch A is pressed, the process directly shifts to the planning mode ST3. As described above, in the present embodiment, direct switching between any of the planning mode ST3, the surface mode ST2, and the log mode ST6 is possible with a single switch operation. Therefore, since there is a high degree of freedom in the transition route to each mode, it is possible to directly transit between the planning mode ST3 and the log mode ST6 with a single operation, so that a dive plan can be made while referring to past diving records. It is convenient and does not take much time to stand.

When it is detected during the log mode ST6 that water has entered through the water entry monitoring switch 30, a function check is automatically performed. If it is confirmed that the sensors and the like are normal, the diving mode ST5 is automatically set. Transition. At this time, when there is an abnormality in the sensor or the like, the fact is notified by an alarm sound from the sound notification device 37 or the like. Thus, the planning mode ST3, the surface mode ST2 (time mode ST1), the log mode ST
6. Since it is possible to automatically shift to the diving mode ST5 from any of the setting modes ST4,
For example, it is convenient that diving can be started immediately after confirming a previous diving record in the log mode ST6 or after setting a diving plan in the planning mode ST3. In addition, since it is possible to shift to the diving mode ST5 from any mode, there is no failure to know for the first time after starting diving that the user has not been prepared to shift to the diving mode ST5 and has failed to shift to the diving mode ST5. Easy to use. In addition, when shifting to the diving mode ST5, a function check is performed in advance, and when an abnormality is detected in the function check, the shift to the diving mode ST5 is automatically stopped, and a notification to that effect is given. This is convenient because there is no failure to shift to the diving mode ST5 as it is, and an abnormality is immediately noticed. In addition, since the amount of inert gas accumulated in the body during diving is not impaired, it is safe from the viewpoint of preventing decompression sickness.

[0092]

As described above, in the information processing apparatus for divers according to the present invention, the diver floats at a position shallower than the preset water depth value for diving end determination and floats at such a shallow position. When the dive end time set in advance is elapsed, it is determined that the dive has ended, and the dive information is recorded and stored as log data for later reproduction. Therefore, according to the present invention, even if the user descends to the deep position after ascending to the shallow position, it is treated as one dive, and is not mistakenly treated as a plurality of dives. Therefore, the diving information can be recorded and reproduced in a form suitable for the actual situation, for example, the diving information is not recorded and reproduced in pieces. Further, even when log data can be recorded only for a maximum of 10 dives, for example, memory over does not occur unnecessarily. Furthermore, not the dive information until the dive end determination time elapses, but the dive information up to the last descent at a position shallower than the dive end determination water depth value is recorded as log data. Useless data is not recorded until the usage time elapses.
