Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for canceling malfunction of an information processing device for diving, which is also called a dive computer.

[0002]

2. Description of the Related Art Information equipment having water depth measurement and timekeeping functions is used during diving. In recent years, based on these measured values, changes in water pressure during diving and changes in atmospheric pressure when moving to high altitudes are measured into the body. Simulates the absorption / emission amount of the inert gas (nitrogen) by calculation, and displays the information for the diver to avoid decompression sickness and safely dive,
An information processing device for diving called a so-called dive computer is becoming popular with divers.

Conventionally, as proposed in Japanese Unexamined Patent Publication No. 8-327355, an information device having a water depth measuring function measures the atmospheric pressure at every predetermined time, and the water detection switch composed of two electrodes enters water. Continuity detection allows immediate diving from any display mode,
That is, the mode is changed to the diving mode, and the water depth measurement is started with the atmospheric pressure value at a predetermined time set to 0 meter. Further, if the water detection switch is continuously turned off after detecting the entry of water and after detecting the predetermined water depth or more, the water depth display is canceled and the time is displayed. Further, it has been proposed that the input state of the water sensing switch is checked by the switch-on count circuit after detecting the entering water and after detecting the predetermined water depth or more, and if it is off, it does not shift to the water depth mode and keeps the time display.

[0004]

However, even after detecting a predetermined water depth value or more after the start of diving, the air bubbles of the breathing air exhaled by the diver or the insulation of the surface of the conduction switch terminal for detecting water entry are detected. The insulation of the water detection switch may be temporarily detected due to film formation, and in such a case, there is a problem that the diving information is not displayed even in water. This is a fatal problem because it is an information device for divers to carry out safe diving management.

[0005] Further, there is a case where the device body is treated with a wet one in the atmosphere, or the water detection switch portion is contacted with a part of the body, so that the conduction is detected. When a change in atmospheric pressure occurs due to a decrease in altitude after a dive mode transition due to such an erroneous operation while moving to a high place such as inside, an erroneous operation of measuring and displaying the pressure difference as the water depth may occur.
At this time, simply canceling the dive mode and returning to the original display state before moving to a high place is
All emission calculations have been cleared to the initial state, the effects of changes in atmospheric pressure due to high altitude on the body have not been added, and continuous measurement, which is an advantage of mobile devices, and calculation of the amount of inert gas in the body based on the measurement results. There is a problem that is not continued.

Therefore, in the present invention, when the diving display state is displayed while moving to a high place, it is determined that the user is moving to a high place based on the detection state of the water detection switch, the pressure change amount and the elapsed time of those states, and the dive mode is set. Even after canceling and returning from the malfunction state to the display state in the atmosphere, by continuously performing and displaying the absorption / exhaustion simulation of the inert gas in the body, the diver can safely dive. The purpose is to provide accurate and reliable information.

[0007]

An information processing device for diving according to the present invention comprises a water depth measuring means for measuring water depth, a time measuring means for measuring elapsed time, and a display section for displaying various information such as water depth and time. External input means for detecting water entry by conduction of two electrodes to start / end water depth measurement (detection of start / end of diving), detection result of the external input means, and measurement by the water depth measurement means When the obtained water depth value is deeper than the preset water depth value for diving determination, the diving determination means for determining that the diver is in diving, and absorption by the body by the elapsed time in water by the timekeeping means
In an information processing apparatus for diving having safety information derivation means for calculating the amount of inert gas discharged, water depth measurement is started by the external input means in atmospheric pressure, and it is determined that the dive is underwater. After that, it is provided with a releasing means for releasing a false recognition state determined to be a dive.

In the present invention, when the operation of the water depth measurement is started by the conduction of the water incoming monitoring switch in the atmosphere, and the movement from the place where the pressure (atmospheric pressure) is low to the place where the pressure is high is performed, for example, In the misidentified state where it is judged as a dive when moving from a high place to a low place, measure the insulation time of the conduction state of the water incoming monitoring switch, and be in the diving state because it has been insulated for more than a predetermined time Is determined, the diving state is canceled, and the state is changed to a state in which the adaptation status of the inert gas in the body after the altitude change in the atmosphere is displayed. Therefore, for example, even if the water pressure value inside the airplane changes and the display continues to display the diving status when the water contact switch is touched by a wet finger while the airplane is on board, the diving status is automatically displayed after a predetermined time. You can check the information in the atmosphere to cancel the, and after that, the diver is ready to use it for diving when he wants to use it, increasing the reliability of the information. Further, even if the diver himself is unconscious and does not recognize the transition to the diving state in the atmosphere, the cancellation is automatically performed, so that the diver's hand is not bothered.

Further, the information processing apparatus for diving according to the present invention measures the atmospheric pressure value at predetermined time intervals while not diving, and measures the atmospheric pressure at the present time by the atmospheric pressure measuring means, and determines it in advance. Advanced rank determination means for determining which of the altitude ranks belong to, advanced rank storage means for storing the determination result by the advanced rank determination means, previous advanced rank stored by the advanced rank storage means and this time It has an altitude rank comparing means for comparing with an altitude rank, and when releasing the diving state by the releasing means, determines the current altitude rank based on the atmospheric pressure measuring means and the altitude rank determining means,
The altitude rank comparison means compares the previous altitude rank before the transition to the diving state and the current altitude rank, and considers that the altitude rank has been changed, and calculates the amount of inert gas (nitrogen) absorption / exhaust in the body. It is characterized in that it is configured to continue and transit to an information display state when the altitude rank is changed.

That is, since the information processing device for diving is a device for simulating the amount of inert gas in the body of the diver at any time, even if it is malfunctioning, the atmospheric pressure value is measured even after the release, and based on the result, By continuing the absorption / emission calculation of the amount of active gas (nitrogen), the accuracy is further improved and the reliability of information display is improved.

Further, in the present invention, in addition to the external input means, a plurality of operating portions are provided, and when a specific input is made from the operating portions, the diving state is released. I am trying. When the diver recognizes the false recognition state, the display mode can be intentionally returned to the state in the atmosphere. Further, when the pressure value is changed in the inspection in the manufacturing process, it may be erroneously recognized, and it is possible to arbitrarily return to the normal state, which is efficient.

Further, the present invention is characterized in that when the diving state is released, a means for notifying the fact by at least visual, auditory or tactile sense is provided. As a result, it is assumed that the altitude rank has been changed, the calculation of the amount of inert gas (nitrogen) absorption / exhaustion in the body is continued, and the diver is notified of the transition to the information display state when the altitude rank was changed. To do.

Further, according to the present invention, when the malfunction is canceled by the canceling means, the diving information recording means does not record. Even if the conditions for recording diving information in the false recognition in the atmosphere are met, it is possible to prevent erroneous recording by not recording the diving information and distinguishing it from the original diving in water. it can.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode of the present invention will be described below with reference to the drawings.

[Overall Structure] FIGS. 1A and 1B are a plan view showing a device body and a part of an arm band of the information processing device for diving of this embodiment, respectively, and the device body from 6 o'clock. It is a side view when seeing. FIG. 2 is a block diagram thereof.

In FIG. 1, the information processing apparatus 1 for diving of this embodiment is also called a so-called dive computer, and measures the amount of nitrogen accumulated in the body during diving (nitrogen partial pressure in the body), and measures this. Based on the results, the rest time to be taken on land after diving is displayed. In this information processing apparatus 1 for diving, arm bands 3 and 4 are connected to a rectangular device body 2 at a 6 o'clock side and a 12 o'clock side of a wristwatch, respectively.
4 allows it to be worn on a wrist and used like a wristwatch. In the device body 2, the upper case 21 and the lower case 22 are fixed in a completely watertight state by a method such as screwing, and a board (not shown) on which various electronic parts and the like are mounted is housed inside. There is. The power source of the entire apparatus is a button type battery (not shown) built in the apparatus body 2.

A display section 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. There is. Therefore, the switch operation is easy even during diving. The switches A and B are an operation unit 5 for selecting and switching each mode performed by the diving 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 formed on the upper surface side of the apparatus body 2 at the 9 o'clock side of the wristwatch. This water entering monitoring switch 30 is provided with two electrodes 31, 32 exposed on the upper surface of the main body of the apparatus, and these electrodes 31, 32 are conducted by seawater or the like, and the resistance value between the electrodes 31, 32 is reduced. Sometimes it is judged that the water has entered. However, this water entering monitoring switch 30 detects that water has entered,
It is used to shift to a diving mode, which will be described later, and does not detect the start of one tie. That is, the arm on which the information processing device for diving 1 is attached may simply be immersed in seawater, and in such a case, it should not be treated as having started diving. Therefore, in the diving information processing apparatus 1 of the present embodiment, the water depth (water pressure) is not less than a certain value by the pressure sensor built in the device body, for example, in the present embodiment, the water depth is 1.
It is considered that the dive started when it became deeper than 5 m (water depth value for judging the start of diving).

As shown in FIG. 2, the diving information processing apparatus 1 of this 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 liquid crystal display panel 11. 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, the switch A,
B, the output from the water input monitoring switch 30 and the like are input.

Since the information processing apparatus 1 for diving displays the normal time and measures the dive time, the clock output from the oscillation circuit 31 is input to the control unit 50 via the frequency dividing circuit 32. Further, the time counter 33 constitutes a time measuring means 68 for measuring time in units of 1 second.

Further, the diving information processing apparatus 1 measures and displays the water depth during diving, and measures the amount of nitrogen gas (inert gas) accumulated in the body from the water depth (water pressure) and the diving time. The pressure sensor 34
(Semiconductor pressure sensor), an amplification circuit 35 for the output signal of the pressure sensor 34, and an A / D conversion circuit 36 for converting an analog signal output from the amplification circuit 35 into a digital signal and outputting the digital signal to the control unit 50. The water depth measuring means 61 is configured. Here, the pressure sensor 34 is
It may be a combination of water depth measurement and atmospheric pressure measurement,
It may be a separate body. If both the water depth measurement and the atmospheric pressure measurement are used, the portable size can be reduced, and the difference between the reference values of the pressure values at the water depth of 0 m and the altitude of 0 m can be easily adjusted. In addition, the pressure sensor 34 configured in the present embodiment is configured to be capable of both water depth measurement and atmospheric pressure measurement, and the surface monitoring mode ST2 and the planning mode S, which will be described later, in which the water monitoring switch 30 is insulated.
In the atmospheric mode of T3 and log mode ST4,
The atmospheric pressure measuring unit 69 regularly measures the atmospheric pressure at predetermined time intervals, and the altitude rank determining unit 95 determines which altitude rank is classified in advance.

Further, since the information processing apparatus for diving of the present embodiment can cope with a sudden change in atmospheric pressure due to movement to a high place and the absorption / exhaustion of inert gas (nitrogen gas) into the body due to a change in altitude, After the altitude rank determination, when there is a change compared with the altitude rank measured last time by the altitude rank comparison means 96, the calculation of absorption / exhaust of the amount of nitrogen in the body is started, and the elapsed time after the altitude rank change and the inert gas adaptation It is configured to transit to the surface mode ST2 that displays time.

Further, in this embodiment, a sounding device 37 and a vibration generating device 38 are configured, and the sounding device 37 can audibly give a warning and the vibration generating device 38 can give a tactile warning. is there. If the amount of nitrogen that dissolves in the body increases, nitrogen may have an anesthetic effect, so the diver may become unconscious while he is not aware of it. It will be possible. Especially for a body whose situation determination and danger recognition are dull, the vibration generator 38 can issue a warning to the diver as a stronger stimulus than other warning functions.

In this embodiment, the control unit 50 includes a CPU 51 that controls the entire apparatus, a control circuit 52 that controls 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 will be described later, is realized by each process performed by the CPU 51 based on the program configured and stored in the ROM 53. The RAM 54 is used as a memory for temporarily recording various data (diving information) obtained during diving, a memory for recording log data for reproducing diving information in a log mode described later, and the like.

[Description of Display Unit] Referring again to FIG. 1A, the display surface of the liquid crystal display panel 11 has eight display regions. Of these eight display areas, the first display area 111 located on the twelve o'clock side of the wristwatch is the largest of the respective display areas, and there are a dive mode and a surface mode (time mode) which will be described later. ), The current water depth, the current month, the water depth rank, and the diving month (log number) are displayed in the planning mode and the log mode, respectively. The second display area 112, which is located at 3 o'clock from the first display area 111, has a dive time, a current time, and no decompression time in the diving mode, the surface mode (time mode), the planning mode, and the log mode, respectively. Available dive time, dive start time (dive time)
Is displayed. In the third display area 113 located at the 6 o'clock side of the first display area 111, the diving mode,
In surface mode (time mode), planning mode, and log mode, the maximum water depth, nitrogen discharge time in the body, safety level, and maximum water depth (average water depth) are displayed. The fourth display area 114, which is located at 3 o'clock from the third display area 113, has a non-decompressible dive time and a water surface pause in the diving mode, the surface mode (time mode), the planning mode, and the log mode, respectively. The time, temperature, and end time of diving (water temperature at maximum water depth) are displayed. In the fifth display area 115, which is located on the 6 o'clock side of the third display area 113, the power capacity shortage warning 104 and the high altitude rank 103 are displayed. In the sixth display area 116 located on the most 6 o'clock side of the liquid crystal display panel 11, the internal nitrogen accumulation amount is displayed in a graph. Also, a seventh display area 117 located on the 3 o'clock side of the sixth display area 116.
Is an area that indicates whether nitrogen (inert gas) tends to be absorbed or discharged when a decompression dive is made in diving mode, and one of the ascent rate violation warnings that the ascent rate is too high. Area for displaying "SLOW" and "DE" as a warning that decompression diving has been reached during diving.
An area for displaying "CO" is configured.

As described above, since the area for displaying the current water depth (first display area 111) is secured at the maximum on the display surface of the liquid crystal display panel 11, the diver is the important data. It is easy to see the current depth display. 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 around the display surface of the liquid crystal display panel 11 due to the upper case 21, it is displayed in the diving mode. Since the display area of the current water depth (first display area 111) is arranged on the side of 12:00, 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 Derivation Means] FIG. 3 shows the calculation of the body nitrogen accumulation amount (body inert gas accumulation amount) in the diving information processing apparatus 1 of the present embodiment, and the body nitrogen excretion based on the result. It is a functional block diagram of safety information derivation means for deriving safety information such as time and non-decompression diving available time.

In FIG. 3, the information processing device 1 for diving absorbs nitrogen contained in the intake air into the body, and
A safety information deriving unit 60 for simulating the discharged state and calculating the internal nitrogen amount (internal nitrogen partial pressure) is configured, and the safety information deriving unit 60 is based on the internal nitrogen amount at a certain water depth. How many hours you can dive without decompression (possible dive time without decompression), and how much time the nitrogen that has excessively dissolved in your body due to the previous diving is discharged on the water surface (nitrogen excretion time in the body / inactivity in the body) The gas discharge time) is derived as safety information for the 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.

In the safety information deriving means 60, first, in order to calculate the nitrogen accumulation amount in the body as a partial pressure, a water depth measuring means using the pressure sensor 34, the amplification circuit 35 and the A / D conversion circuit 36 shown in FIG. 61, CPU 51, R shown in FIG.

1. Internal nitrogen partial pressure calculation means 64 realized as the functions of ROM 53 and RAM 54, internal nitrogen partial pressure storage means 65 using the RAM 54 shown in FIG. 2, and clocking means using the time counter 33 shown in FIG. 68, C shown in FIG.
A comparison unit 6 which is realized as a function of the PU 51, the ROM 53, and the RAM 54, and which compares the data stored in the respiratory air nitrogen partial pressure storage unit 63 and the internal nitrogen partial pressure storage unit 65.
6, CPU51, ROM53, RAM54 which is shown in Figure 2
The half-saturation time selecting means 67 is realized as the function of.

Of these components, respiratory air nitrogen partial pressure calculation means 62, internal nitrogen partial pressure calculation means 64, comparison means 6
6. The half-saturation time selecting means 67 is the CPU 51, R of FIG.
It can be realized as software by the OM 53 and the RAM 54, but 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 the water pressure P (t) corresponding to the time t.

The respiratory air nitrogen partial pressure calculating means 62 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 means 61. The respiratory air 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) in the dive.

The respiratory air nitrogen partial pressure storage means 63 stores the P calculated by the respiratory air nitrogen partial pressure calculation means 62 according to the above equation.
The value of IN ₂ (t) is stored.

The in-vivo nitrogen partial pressure calculating means 64 calculates the in-vivo nitrogen partial pressure PGT for each tissue having different absorption / exhaust rates of nitrogen.
Calculate (t). Taking one tissue as an example, the tissue nitrogen partial pressure PGT absorbing / discharged from dive time t = _{t 0} to _{t E (t E)} is, _{t 0} o'clock tissue nitrogen partial pressure PGT (t
₀ ), dive time t _E , and half saturation time T _H.

[0034] 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)} Respiratory air nitrogen partial pressure PG in the process of reaching the partial pressure PG in the body
It corresponds to the time (half time) until the intermediate pressure value between T (t ₀ ) and the respiratory gas nitrogen partial pressure PIIG is reached.

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

[0036]

[Equation 1] Here, k is a constant that is experimentally obtained.

Next, the comparing means 66 causes the respiratory nitrogen content to be reduced.
PIN as a result of the pressure storage means 63 _Two (T) and internal nitration
PGT (t) as a result of the elementary pressure means 5 is compared and
As a result, the partial pressure of nitrogen in the body is selected by the half-saturation time selecting means 67.
Half saturation time T used in the calculation means 64_H Is variable
It

For example, when t = t ₀ , respiratory air nitrogen partial pressure PIN ₂ (t ₀ ) and internal nitrogen partial pressure PGT (t ₀ )
Is stored in the respiratory air nitrogen partial pressure storage means 63 and the in-vivo nitrogen partial pressure storage means 65, respectively, the comparison means 6
6 compares this PIN ₂ (t ₀ ) with PGT (t ₀ ).

Then, the internal nitrogen partial pressure calculating means 64 is controlled by the half-saturation time selecting means 67 as follows, and t
The nitrogen partial pressure PGT (t _E ) in the body at = t _E is calculated.

[0040]

[Equation 2]

[Equation 3] In the above two equations, k is a constant and T _H2 <T _H1 is calculated.

Note that PGT (t ₀ ) = PIN ₂ (t ₀
), Half saturation time T _H = (T _H2 + T _H1 ) /
It is preferably calculated as 2. In addition, these times (measurement about t ₀ and t _E ) are the time measuring means 6 of FIG.
Managed by 8.

Here, PGT (t ₀ )> PIN ₂ (t
₀ ) is the case where nitrogen is excreted from the body, and when PGT (t ₀ ) <PIN ₂ (t ₀ ),
This is the case when nitrogen is absorbed into the body. Changing the half-saturation time at these times means that the half-saturation time is long when nitrogen is discharged, and it takes time to discharge the nitrogen. Conversely, the half-saturation time is changed when nitrogen is absorbed. It is short and the time taken for absorption is short compared to the time taken for discharge. By doing so, the simulation of the amount of nitrogen in the body can be performed more strictly. Therefore, if you set an allowable value for the internal nitrogen partial pressure, the time required to reach this allowable value at a certain water depth (water pressure) (no decompression dive time / safety information) and the internal nitrogen partial pressure on the water surface The time (nitrogen excretion time in the body / safety information) until the value decreases to the equilibrium value can be accurately obtained. In this way, the diving information processing apparatus 1 of the present embodiment is configured with the diving possible time deriving means 92 and the body nitrogen discharging time deriving means 91 for deriving the non-decompression diving possible time and the nitrogen discharging time in the body as safety information of the diver. Has been done.

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

That is, as shown in FIG. 5, in the diving information processing apparatus 1, the water depth measuring means 61 shown in FIG.
The outputs of the timekeeping means 68 and the water entry monitoring switch 30 are both input to the control section 50, and the control section 50 includes a dive start / end determination means 81 and a dive information recording means 85 that uses 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 determination means 81 is set at time T1.
Incoming water switch 3 indicating that the diver has entered the water
After 0 is detected, it is determined that the dive is started when the dive depth is deeper than the water depth value of 1.5 m set as the dive start determination water depth value 82 at time T12.
As a result, measurement of dive time is started. Diving time measured in this way, average water depth, dive start time,
Diving information such as the amount of body nitrogen in the dive, the maximum water depth, the dive time, the water temperature at the maximum water depth, the dive date and time, and the altitude rank is updated in the dive information recording means 85 during the dive as necessary. Meanwhile, the data is recorded in the temporary recording area 86 (temporary recording unit) configured in the RAM 54.

After the dive is started, the dive start / end determining means 81 determines time T13 based on the measurement result of the water depth measuring means 61 and the measurement result of the time measuring means 68.
Is set as the depth value 83 for judging the end of diving.
Even if the diver floats at a position shallower than the water depth of 5 m,
If the 10 minutes set as the dive end determination time 84 has not elapsed, it is not determined that one dive has ended. Therefore, the dive start / end determination means 81
Is 1 even if the diver floats at a position shallower than the water depth value of 1.5 m (water depth value 82 for judging the end of diving) at time T13.
Before 0 minutes (diving end judgment time 84) has elapsed,
At time T14, it is determined that one dive is continuing when the player dives to a position deeper than the water depth value of 1.5 m (water depth value 82 for judging the end of diving).

That is, the dive start / end determination means 81
At time T15, the diver floats at a position shallower than the water depth value of 1.5 m (water depth value 83 for determining the end of diving), and
It is judged that the diving is completed for the first time when 10 minutes (time for diving completion determination 84) has elapsed at time T16. Then, the dive information recording means 85 starts the dive end determination water depth value 8 from the time (time T12) when the dive is first deeper than the dive start determination water depth value 82.
The dive information recorded in the temporary recording unit 86 up to the time of the last ascending to a position shallower than 3 (time T15) is determined as the log data for one dive, and is recorded 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 is used, the diving from time T12 (diving start time) to time T15 (diving end time) is regarded as one dive, even if the dive is as shown in FIG. The dive information can be displayed and reproduced later on the liquid crystal display panel 11 of the display unit 10.

Here, while diving, the liquid crystal display panel 11 displays diving information necessary for diving, such as the current water depth, dive time, maximum water depth, non-decompressible dive time, internal nitrogen graph, and altitude rank. In this form,
The diver floats at a position shallower than the water depth value of 1.5 m (dive end determination water depth 83), and 10 minutes (dive end determination time 84) after that, the liquid crystal display panel 11 displays The dive information of continues to be displayed. As described above, at time T13, even if the diver floats at a position shallower than the water depth value of 1.5 m (dive end value 82 for dive end determination), before 10 minutes (time 84 for dive end determination) elapses. This is because, once again, at time T14, when diving to a position deeper than the water depth value of 1.5 m (dive end value 82 for diving end determination), it is considered that one dive is continuing. Furthermore, a water depth value of 1.5 m (water depth value 83 for judging the end of diving)
Even after the diver has floated to a shallower position and 10 minutes (diving end determination time 84) has elapsed from that time until the diver rises above the water surface and the electrodes 31 and 32 return to the insulating state, the liquid crystal display panel At 11 the above information continues to be displayed. That is, the electrodes 31 and 32 conduct when the diver enters the water and the water entering monitoring switch 30 detects the diver, and then the diver rises above the water surface and the electrodes 31 and 32 of the water entering monitoring switch 30 return to the insulated state. Until then, the same information as the dive mode is continuously displayed on the liquid crystal display panel 11.

Further, in the present embodiment, at time T15, the diver lasts a position shallower than 1.5 m (dive end determination water depth value 83) at a position shallower than the last position, and at time T16, 10 minutes (dive end determination time 84) is reached. Until the time elapses, the diving information recorded in the temporary recording unit 86 can be displayed on the liquid crystal display panel 11 of the display unit 10 by operating a predetermined switch. Therefore, even before the dive information of this dive is confirmed as log data, the dive information of this dive can be reproduced and displayed, which is convenient.

As described above, according to the information processing apparatus for diving 1 of the present embodiment, even if the user ascends to a shallow position and then dives again to a deep position, it is treated as one dive and is mistakenly treated as a plurality of dives. I will never be told. 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 bare dive from being recorded in the log data recording area 87.

Here, since the log data can be recorded in the log data recording area 87 only for a maximum of 10 times of diving, for example, when diving more than that, old data is automatically deleted in order. Even with such a configuration, in the present embodiment, even if the user ascends to a shallow position and then dives again to a deep position, it is treated as one dive, so important log data is updated and deleted carelessly. Never.

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

[Functional structure for canceling diving state at the time of malfunction] The overall structure has been described above.
Then, the atmospheric pressure measuring unit 69 periodically measures the atmospheric pressure, and the altitude rank determining unit 95 determines which altitude rank is classified in advance, and the altitude rank comparing unit 96.
As a result, after the last atmospheric pressure measurement, the altitude rank storage means 97 compares with the previous altitude rank stored in the RAM 54, and when there is a change, the calculation of absorption / exhaust of the amount of nitrogen in the body is started, and the rest after the dive is finished. It is configured to transit to the surface mode ST2 for displaying in time.

A prominent example of such a change in atmospheric pressure is, for example, a change in altitude during boarding of an airplane. Here, the state of sudden pressure change due to boarding an airplane,
The configuration for canceling the malfunction in the present invention will be described in detail with reference to FIGS.

At time T21, the atmospheric pressure measuring means 69 measures the atmospheric pressure and stores it in the RAM 54 as the altitude rank by the altitude rank storage means 97. At time T22, conduction is detected by contact of the water monitoring switch 30 with a wet finger or the like, and the water depth measuring means 61 starts water depth measurement. After that, for example, when the pressure drops by 1500 m or more, the atmospheric pressure value becomes high. The difference is equivalent to 1.5 m in terms of water pressure, and is 1.5 m at time T23 by the dive start / end determination means 81.
It is determined to be diving by comparison with (diving start determination water depth value 72). The insulation of the water entry monitoring switch 30 is detected at time T24, but after time T23, it is determined that the dive is in progress, so the dive mode ST5 is continued and the water depth measurement means 61 is also performing water depth measurement.

Further, at time T24, the water incoming monitoring switch 30
When the electric conduction state of is detected as insulation, the releasing means 93 causes the water surface rest time measuring means 83 to start timekeeping with the water insulation pause time as the water surface rest time. The release means 93 compares the water surface rest time with the release determination time 94 (10 minutes) every predetermined time, and if more than that time has elapsed, it is determined that the dive mode ST5 is a malfunction during diving. The display content is judged and transits to the surface mode ST2 and displayed on the display panel. That is, the releasing means 93 is the water intrusion monitoring switch 3
Even after the continuity detection of 0 is detected, even if the dive start / end determination means 81 determines that the dive is in progress, the time during which the water entry monitoring switch 30 continues to detect insulation at time T25 is 10 of the release determination time 94. When more than a minute has passed, the water depth measurement and the dive time measurement are stopped, and the display changes to the surface mode 2.

Further, the sounding device 3 informs that the malfunction is released.
The diver is notified by the alarm from 7 and the vibration in the vibration generator 38. Further, the display unit 10 may be informed by causing the light emitting body to emit light. That is, the diver is surely notified that the misidentified state has been definitely released and the information displayed on the display panel 11 has been updated. With these operations, when the diver notices after getting off the airplane, the display does not remain in the diving state and the information in the atmosphere can not be confirmed, and the change in the pressure applied to the body is displayed on the display unit, and This is convenient because it is possible to display information until the active gas reaches an equilibrium state.

In this embodiment, the release determination time 94 is set to 10 minutes like the dive end determination time 85, and the control unit 50
Although the ROM 53 and the CPU 51 are improved in efficiency, the time until the release operation is further set to, for example, the dive determination time 8
A shorter time counter may be applied, such as using a shorter time such as 8.

In the information processing apparatus 1 for diving of the present embodiment, the button switch A, which is a specific operation different from selecting each mode of the operation unit 5 formed in the apparatus body after time T23, The diving state can be released by simultaneously pressing the button switches B and continuing the simultaneous pressing state for a predetermined time or longer. As a result, the diver can confirm the malfunction state, and if he / she wants to cancel the condition immediately, it can be canceled by performing a specific operation, which is convenient. Furthermore, in the manufacturing process, for example, when performing a quality inspection in an environment where the atmospheric pressure is reduced by an atmospheric pressure adjusting device or the like, a malfunctioning diving state may occur, and at that time, the diving state may be released by a specific operation. Since it is configured, it is practical because it must be efficiently flowed to the next step. The environment in which the atmospheric pressure is lowered refers to a state lower than the standard atmospheric pressure value at a position at an altitude of 0 meters above sea level, for example, an atmospheric pressure value in an altitude area (up to about 2000 meters) where humans normally live.

Further, in the present embodiment, the canceling means 93 determines that it is malfunctioning, and at time T25 when transitioning to the surface mode ST2, which is the display in the atmosphere, the atmospheric pressure measuring means 69 measures the atmospheric pressure to determine the altitude rank. Means 9
Altitude rank determined by 5, and altitude rank comparison means 9
6, the previous altitude rank measured and determined at the previous time T21 is compared, and it is determined that there is a change to a lower altitude rank. As a result, it is determined that the altitude has changed, and the surface mode ST2 is transitioned to a state in which the in-body inert gas absorption / exhaust calculation is being performed instead of the simple time display state.

That is, the display information of the display panel 11 which is malfunctioning is displayed in water, but the environmental pressure at that time is always measured, and the absorption / exhaust calculation of the inert gas in the body is continued with the result. In order to display the surface mode ST2, which indicates that the amount of inert gas in the body has been changed and continues even after the malfunction is released,
It is possible to provide information by more closely simulating the actual state of the body. The safety of the subsequent diving can be further enhanced, and the reliability of the display information when returning to the normal state can be improved.

[Floating speed monitoring function] The diving information processing apparatus 1 is configured to monitor the flying speed of the diver during the diving mode described later.
It is realized as the following configuration by utilizing the functions of U51, ROM53, RAM54 and the like.

That is, as shown in FIG. 5, in the diving information processing apparatus 1, the levitation speed measurement for measuring the levitation speed at the time of levitation based on the measurement result of the timing means 68 and the measurement result of the water depth measurement means 61. The means 75 and the measurement result of the levitation speed measuring means 75 are compared with a preset levitation speed upper limit value 76. If the current levitation speed is faster than the levitation speed upper limit value 76, a warning that the levitation speed is violated is issued. Ascending speed violation warning means 77 is configured. The floating speed measuring means 75 is the CPU 51 and the ROM 5 shown in FIG.
3, the floating speed violation warning means 77 is realized by the arithmetic function of the RAM 54, and the CPU 51, R shown in FIG.
OM53, RAM54, sounding device 37, vibration generator 3
8. It is realized as a function such as display on the liquid crystal display panel 11.

In this embodiment, ascending speed violation warning means 7
Reference numeral 7 compares the levitation speed upper limit value for each water depth range stored in the ROM 53 as the levitation speed upper limit value 76 with the current levitation speed, and the current levitation speed corresponds to the current water depth. If it is faster than 76, the display on the liquid crystal display panel 11, the alarm sound from the alarm device 37,
Furthermore, a warning of a floating speed violation is issued by a method of transmitting vibration from the vibration generator 38 to the diver, and when the floating speed returns to a state slower than the floating speed upper limit value 76, the warning of a floating speed violation is stopped. In this embodiment, the following values are shown in each water depth range as the floating speed upper limit value 76. This time's water depth measured value The floating speed upper limit value is less than 1.8 m No warning 1.8 m to 5.9 m 8 m / min (about 0.8 m / 6 seconds) 6.0 m-17.9 m 12 m / min (about 1.2 m / 6
Second) 18.0 m or more 16 m / min (about 1.6 m / 6 sec) is set. That is, in deep water,
This is because the water pressure ratio before and after ascending per unit time is small even when ascending at the same ascending speed, so that decompression sickness can be sufficiently prevented even if a relatively large ascending speed is allowed. On the other hand, when the water depth is shallow, the water pressure ratio before and after levitation per unit time is large even if the levitation speed is the same, so that only a relatively low levitation speed is allowed.

In this embodiment, the water depth value per 6 seconds is stored in the ROM 53 as the upper limit value of the floating speed. this is,
As shown in FIG. 7, the water depth is measured every 1 second, but in order to prevent the movement of the arm wearing the diving information processing apparatus 1 from affecting the ascent rate, the ascent rate is 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 regarded as the floating speed, and the above floating speed upper limit value (m / 6 seconds) Because it compares with.

Further, the diving information processing apparatus 1 of the present embodiment stores and holds diving information (various data such as diving date, diving time, maximum water depth) in the log data recording area 87 of the RAM 54. Diving information recording means 85
The diving information recording means 85 also records in the log data recording area 87 as log data whether or not a warning has been issued by the ascending speed violation warning means 77. Therefore, whether or not the ascending speed is violated during the current diving is also reproduced and displayed on the liquid crystal display panel 11 later. However, the diving information recording means 85 records the log data recording area 8 as the log data when the ascending speed is violated only when the warning is issued twice or more continuously during one diving.
Record at 7. Therefore, when the levitation speed is erroneously measured high due to the movement of the diver's arm, the fact that the levitation speed is violated is not recorded as log data.

Further, since the information processing apparatus 1 for diving of the present embodiment treats it as the first time diving is performed when the water depth is deeper than 1.5 m for 3 minutes or more.
When the water depth rises to a position shallower than 1.5 m, the water depth is considered to be 0 m, and the display is 0 m.
Therefore, when the ascending speed violation warning means 77 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 where the depth of water is slightly deeper than 1.5 m. Even if it is shallower than 1.5m and is considered to be 0m, even though it keeps the ascent speed,
The ascending speed violation warning will be issued. as a result,
Divers question the reliability of ascending speed warnings. However, in this embodiment, the current water depth is a predetermined value (1.5
When shallower than m), regardless of the ascent speed, the ascent speed warning is not issued. Therefore, since the above-mentioned unnatural warning is not issued, the reliability of this warning can be enhanced. That is, as shown in FIG. 7, for example, the water depth measured last time during ascent is 1.8 m, and as shown by the solid line L11 from this position, the current water depth measured after 6 seconds is 1.5 m. If it is shallower than (the depth value for judging the end of diving), the warning that the ascending speed is violated is not issued.

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

Therefore, after the end of the dive, 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 taken for the diver and excess nitrogen is discharged from the body. After being told, you can warn you to board the plane.

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

(Time mode ST1) Time mode ST1
Is a function to carry on land without switch operation and when the nitrogen in the body is in equilibrium. The liquid crystal display panel 11 shows the current date 100, the current time 101, and the altitude rank 103 (see FIG. 1). If the altitude rank is rank 0, the mark is not displayed.) Is displayed. The altitude rank 103 automatically measures the altitude of the current location and displays it in three ranks. At the current time 101, the display of the current time 1
Notify that it is 01. For example, in the state shown in FIG. 8, it is displayed that it is now 10:06 on December 5th.

Further, since the atmospheric pressure changes when the user goes up and down at a high altitude and a low altitude, the dissolution of nitrogen into the body and the discharge of nitrogen occur regardless of the past diving. Therefore, in the information processing apparatus 1 for diving of the present embodiment, even in the time mode ST1, when such an altitude change occurs, decompression calculation is automatically started and the display is changed. That is, although not shown, the time after the altitude changes, the time until the internal nitrogen reaches an equilibrium state, and the amount of nitrogen that is discharged or dissolved from the present to the equilibrium state are displayed.

In this time mode ST1, when switch A is pressed, the mode directly shifts to planning mode ST3, and when switch B is pressed, the mode directly shifts to log mode ST6. After pressing the switch A, if the switch B is pressed for 5 seconds while the switch A is being pressed, the mode shifts to the setting mode ST4.

During this time mode ST1, FIG.
When it is detected that the water has entered through the water entering monitoring switch 30 shown in (4), the function is automatically checked, and if it is confirmed that the sensor and the like are normal, the mode automatically shifts to the diving mode ST5. At this time, when there is an abnormality in the sensor or the like, the alarm device 3 shown in FIG.
The alarm sound from 7 is used for notification.

During this time mode ST1, (during the surface mode ST2), the diving information processing apparatus 1 automatically moves to the surface mode ST2 when the water entry monitoring switch 30 that has been conducting is in an insulated state after the end of the dive. Move to. The surface mode ST2 is a function to be carried on land until 48 hours have passed since the last diving. In this surface mode ST2, the data displayed in the time mode ST1 (current date 10
(0, current time 101, altitude rank), and a guideline for changes in the amount of nitrogen in the body after the end of the dive are displayed. That is, the time until the excess nitrogen dissolved in the body is discharged and the equilibrium state is reached is 20 hours for discharging nitrogen in the body.
Displayed as 1. This body nitrogen discharge time 201 is
Count down the time to reach equilibrium. Nothing is displayed after the internal nitrogen discharge time 201 reaches 0 hour 00 minutes. In addition, the elapsed time after diving is the surface dwell time 2
This water surface rest time 202 is displayed as 02, and the time is started as the end of the dive when the last surface of the water is shallower than 1.5 m in the diving mode ST5. Becomes Therefore, in the information processing apparatus 1 for diving, the surface mode ST2 is set on land until 48 hours have elapsed after the end of diving, and the time mode ST1 is set thereafter. In the state shown in FIG. 8, it is displayed that the current time is 11:58 on December 5, and 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 diving performed so far corresponds to four nitrogen in the body nitrogen graph 203, and the time from this state until the excess nitrogen in the body is discharged to reach the equilibrium state (Body nitrogen discharge time 20
1) is displayed as, for example, 10 hours and 55 minutes.

In this surface mode ST2, when switch A is pressed, the mode directly shifts to planning mode ST3, and when switch B is pressed, the mode directly shifts to log mode ST6. After pressing switch A, if switch B is pressed for 5 seconds with switch A pressed, the setting mode S
Move to T4.

During the surface mode ST2, when it is detected that water has entered through the water entering monitor switch 30, a function check is automatically performed, and if it is confirmed that the sensor is normal, the diving mode is automatically changed to ST5. 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 alarm device 37.

(Setting mode ST4) Setting mode ST4
Is a function for performing ON / OFF setting of a warning alarm and setting of a safety level in addition to the setting of month / day 100 and current time 101. In this setting mode ST4,
Current month 100, year 106, current time 101, safety level (not shown), alarm ON / OFF (not shown), and altitude rank are displayed. Among these items, the safety level is usually It is possible to set two levels, that is, a level for performing decompression calculation of 1 and a level for performing decompression calculation premised on moving to a place of an altitude rank one rank higher after diving. The alarm ON / OFF is a setting for setting whether or not various warning alarms are sounded from the alarm device 37. If the alarm is set OFF, the alarms do not sound. Therefore, in a device such as the diving information processing device 1 in which dead batteries are particularly fatal, the power consumed for the alarm can be reduced, which is convenient.

In this setting mode ST4, each time the switch A is pressed, the setting item switches in the order of hour, second, minute, year, month, day, safety level, alarm ON / OFF, and the display of the corresponding portion blinks. To do. At this time, if switch B is pressed, the numerical value or character of the setting item changes, and if the switch is kept pressed, the numerical value or character changes rapidly. Alarm ON / O
When switch A is pressed while FF is blinking, the surface mode ST2 or time mode ST1 is returned to. If neither switch A or B is pressed for 1 to 2 minutes, surface mode ST2 or time mode ST
Automatically returns to 1.

During this setting mode ST4, even when it is detected that water has entered through the water entering monitoring switch 30, a function check is automatically performed, and if it is confirmed that the sensors are normal, the diving mode ST5 is entered. 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 alarm device 37.

(Planning Mode ST3) The planning mode ST3 is a mode for inputting the maximum water depth of the next dive and the standard of the dive time. In this mode, depth of water 301, no decompression diving time 30
2, safety level, altitude rank, water surface down time 20
2. The internal nitrogen graph 203 is displayed. Water depth rank 3
The display of the rank of 01 changes from the low rank to the high rank in order, and the non-decompression diving possible time 302 at each water depth rank 301 is displayed. For example, water depth rank 301 is 9m, 12m, 15m, 18m, 21
m, 24m, 27m, 30m, 33m, 36m, 39
It changes every 5 seconds in the order of m, 42m, 45m, 48m. At this time, if the time mode ST1 shifts to the planning mode ST3, it is the first diving plan in which there is no excessive nitrogen accumulation in the body due to past diving.
When the body nitrogen graph 203 is 0 and the water depth is 15 m, the non-decompression dive time 302 is displayed as 66 minutes. Therefore, it can be seen that no-decompression diving is possible for less than 66 minutes at a water depth of 12 m or more and 15 m or less. On the other hand, if the transition from the surface mode ST2 to the planning mode ST3 is made, it is a plan of repeated diving in which excess nitrogen is accumulated in the body due to past diving. Maximum water depth is 15m
In this case, the non-decompression dive time 302 is displayed as 49 minutes. Therefore, it can be seen that no-decompression diving is possible for less than 49 minutes at a water depth of 12 m or more and 15 m or less.

In the planning mode ST3, if the switch A is kept pressed for 2 seconds or more until the water depth rank 301 is displayed as 48 m, the surface mode ST2 is directly entered. Further, after the water depth rank 301 is displayed as 48 m, the time mode ST1 or the surface mode ST2 is automatically entered. Further, when there is no switch operation for a predetermined period, the surface mode ST2 or the time mode ST1 is automatically entered, which is convenient because it is not necessary to perform the switch operation each time. On the other hand, when the switch B is pressed, the log mode ST6 is directly entered.

During the planning mode ST3,
When it is detected that water has entered through the water input monitor switch 30, a function check is automatically performed, and if it is confirmed that the sensor is normal, the diving mode ST5
Automatically transitions 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 alarm device 37.

(Diving mode ST5) The diving mode ST5 is a mode for diving. In the no-decompression diving mode ST51, the current depth 501, diving time 502,
This is a function for displaying information necessary for diving, such as maximum water depth 503, non-decompression dive time 302, in-vivo nitrogen graph 203, and altitude rank. For example, in the state shown in FIG. 8, 12 minutes have passed since the dive was started, the water depth is 16.8 m, and it is displayed that the user can continue non-decompression diving for another 42 minutes at this water depth. .
In addition, it is displayed that the maximum water depth to date is 20.0 m, and the current amount of internal nitrogen is the internal nitrogen graph 203.
A message indicating that the four marks are lit is displayed.

Here, for the purpose of informing the diver of the transition to the diving mode ST5, the display of the current water depth 501 or the like 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 have to worry about whether or not the diving mode ST5 is functioning normally, which is convenient. .

In the diving mode ST5, as described above as the function of monitoring the ascending speed, rapid ascending causes decompression sickness. Therefore, the current ascending speed is obtained every 6 seconds, and the ascending speed and the current water depth are calculated. When the ascent velocity obtained this time is faster than the ascent velocity allowable value, the alarm device 37 issues an alarm sound (ascent velocity violation warning) at a frequency of 4 kHz for 3 seconds. , Liquid crystal display panel 1 so as to slow down the floating speed
In 1, the display of "SLOW" and the display of the current water depth are alternately blinked at a cycle of 1 Hz to give a floating speed violation warning. Then, when the ascending speed drops to a normal level, the ascending speed violation 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 as the current time display mode ST52 only while the switch A is continuously pressed. In the state shown in FIG. 8, it is displayed that the time is now 10:18 and the water temperature is 23 ° C. In this way, 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 it is configured to always display only the data necessary for diving on a small display surface (no-decompression diving mode ST51), the current time 101 and the like can be displayed as needed (current time display mode ST52), It is convenient. Moreover, since the switch operation is used to switch the display even in the diving mode ST5 as described above, the information that the diver wants to know can be displayed at an appropriate timing.

During the diving mode ST5, when the water depth rises to a depth of less than 1.5 m, it is treated as if the diving has been completed, and when the water entering monitoring switch 30 which has been conducted is in the insulated state. The mode automatically shifts to the surface mode ST2. During this time, the dive information recording means 78 shown in FIG. 3 defines the dive information (diving date) as one dive from when the water depth becomes 1.5 m or more to when it finally becomes shallower than 1.5 m. , Various data such as diving time and maximum water depth) are stored and held in the diving information recording means 78 (RAM 54). At the same time, when the above-mentioned ascending speed violation warning is continuously issued twice or more during the current diving, the fact is also recorded as diving information.

The information processing apparatus for diving 1 of this embodiment is
Although it is constructed on the premise of no-decompression diving, if a decompression diving situation 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 diving time 502, the internal 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. 8, 2 from the start of diving
After 4 minutes, it is displayed that the water depth is 29.5 m. Also, since the amount of nitrogen in the body exceeds the maximum allowable value and is dangerous, the water depth is 3 m while maintaining a safe ascent speed.
You will be ascended to where, and an instruction will be displayed to stop the decompression for 1 minute. In addition, an instruction to take a minimum of 5 minutes to reach the surface of the water as a safe ascent rate is displayed. Furthermore, an upward arrow 508 indicates that the amount of nitrogen in the body is currently increasing. Therefore, the diver floats after stopping the decompression based on the above display contents, but while the decompression is being performed, the downward arrow 509 indicates that the amount of nitrogen in the body tends to 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 has stored in the log data recording area 87 various kinds of diving information when diving deeper than the depth of 1.5 m for 3 minutes or more 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 a maximum of 10 log data is stored and retained. When diving more than that, old data is deleted in order, and the latest 10 data are always recorded. Is remembered.

In this log mode ST6, the log data is displayed on two screens that switch every 4 seconds. First
Screen ST61, diving date 601, average water depth 50
9, the dive start time 603, the dive end time 604, the altitude rank, and the body nitrogen graph 203 when the dive is finished are displayed. On the second screen ST62, the log number 605, which is the diving number on that day, the maximum water depth 608, the diving time 606, the water temperature 607 at the maximum water depth, the altitude rank,
The in-vivo nitrogen graph 203 at the end of the dive is displayed. For example, in the state shown in FIG. 8, when the altitude rank is 0, the second dive on December 5 has a dive of 1
It started at 0:07 and ended 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 completion of the diving, the nitrogen graph 203 in the body dissolved four nitrogen in the body. The message 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, when the speed violation warning is issued twice or more during the diving currently displayed, the fact is notified, for example, by the liquid crystal display panel 11
“SLOW” is displayed in the seventh display area 117 of.

In the log mode ST6, each time the switch B is pressed, the new data is switched to the old data, and after the oldest data is displayed, the time mode ST1 or the surface mode ST2 is entered. Even if the switch B is kept pressed for 2 seconds or more during the process, the mode is shifted to the time mode ST1 or the surface mode ST2. Further, even when neither of the switches A and B is pressed for 1 to 2 minutes, the surface mode ST2 or the time mode ST1 is automatically returned, which is convenient because it is not necessary to perform the switch operation each time. On the other hand, when the switch A is pressed, the mode directly shifts to the planning mode ST3. As described above, in the present embodiment, it is possible to directly switch between any of the planning mode ST3, the surface mode ST2, and the log mode ST6 by one switch operation. Therefore, since there is a high degree of freedom in the route of transition to each mode, it is possible to directly transition between the planning mode ST3 and the log mode ST6 with a single operation. It is convenient and easy to set up.

In addition, during the log mode ST6, when it is detected that water has entered through the water entry monitor switch 30, a function check is automatically performed, and if it is confirmed that the sensor is normal, the dive mode is automatically changed to ST5. Shift to the target. At this time, when there is an abnormality in the sensor or the like, the fact is notified by an alarm sound from the alarm device 37.

In this way, the planning mode ST3,
Since it is possible to automatically shift to the diving mode ST5 from any of the surface mode ST2 (time mode ST1), the log mode ST6, and the setting mode ST4, for example, after confirming past diving records in the log mode ST6. , Or planning mode ST
After setting the diving plan in 3, you can start diving immediately and it is convenient. In addition, when it is detected that water has entered through the water monitoring switch 30 even in any mode, the diving mode ST is automatically set.
Since it is possible to shift to 5, it is not necessary to manually switch to the diving mode. In other words, when there is no preparation for shifting to the diving mode ST5, there is no failure to know that the failure to shift to the diving mode ST5 is made only after the dive is started.
Easy to use. Moreover, a function check is performed in advance when shifting to the diving mode ST5, and when an abnormality is detected in the function check, the diving mode ST5
Since the shift to 5 is automatically stopped and the fact is notified, there is no failure to shift to the diving mode ST5 while there is an abnormality, and the abnormality is immediately noticed, which is convenient. Further, it is safe from the viewpoint of preventing decompression sickness because it does not fail to monitor the amount of inert gas accumulated in the body during diving.

[0096]

As described above, in the information processing apparatus for diving according to the present invention, even if the diver enters the diving mode when he or she is not intending to move during high altitude, the water detection switch is insulated. Since the diving state is released and the state transits to the state in the atmosphere when the state time has passed the preset release determination time, it is not necessary to return to the 0 m depth measurement point. Furthermore, even if there is a change in pressure due to the movement of the wearer, the calculation of absorption / exhaust of the amount of nitrogen in the body is regularly performed using the measured values without interruption, and continues even if the display mode changes. Since it can be simulated more strictly, safety and reliability can be improved.

Therefore, according to the present invention, after it is accidentally changed to the diving state in the atmosphere, it is not continuously treated as the diving state, and the state automatically shifts to the information providing state in the atmosphere. Information can be provided in a conforming manner, and it has the effect of further improving reliability. In addition, the diver (user) does not need any troublesome operation for releasing. Furthermore, the release determination means is RO
Since it is executed by the program stored in M53, it does not rely on the control by the conventional electronic circuit, so that the mounting area of the circuit board can be reduced, which contributes to downsizing and thinning of the device.
