Further, an operation unit 5 for selecting / switching various operation modes in the dive computer 4 is formed on the lower side of the apparatus main body 2, and the operation unit 5 has two push button type switches A and B. ing. A diving operation monitoring switch 30 using a continuity sensor used to determine whether or not diving has been started is configured on the left side of the apparatus main body 2 in the drawing. This diving operation monitoring switch 30 has electrodes 30A and 30B provided on the front side of the apparatus main body 2 in the drawing, and the resistance between the electrodes 30A and 30B is established between the electrodes 30A and 30B by seawater or the like. It is determined that the water has entered when the value becomes smaller. However, the diving operation monitoring switch 30 is only used for detecting that water has entered and for shifting the operation mode of the dive computer 4 to the diving mode, and detects that the diving has actually started. Is not used for That is, there are cases where the arm of the user wearing the dive computer 4 has just been immersed in seawater, and it is not preferable to determine that diving has started in such a state.

For this reason, in this dive computer, when the water pressure (water depth) exceeds a certain value by the pressure sensor built in the apparatus main body 4A, more specifically, when the water pressure becomes equal to or more than 1.5 [m] as the water depth. It is considered that the dive has been completed when the water pressure is less than 1.5 [m] at the water depth.
As shown in FIG. 3, the dive computer 4 is roughly classified into an operation unit 5 for performing various operations, a display unit 10 for displaying various information, a diving operation monitoring switch 30, an alarm sound from a buzzer, and the like. A sounding device 37 that performs notification to the user by vibration, a control unit 50 that controls the entire dive computer, a pressure measuring unit 61 that measures atmospheric pressure or water pressure, and a timekeeping unit that performs various timing processes 68, an acceleration measuring unit 70 that measures the acceleration of the wearing part of the dive computer 4, a temperature measuring unit 80 that measures the ambient temperature of the diver, and a communication device 90 that communicates with the outside.

The display unit 10 includes a liquid crystal display panel 11 for displaying various types of information and a liquid crystal driver 12 for driving the liquid crystal display panel 11.
The control unit 50 is connected to the switches A and B (= the operation unit 5), the diving operation monitoring switch 30, the sound reporting device 37, and the vibration generating device 38, and controls the entire device, and a CPU 51 under the control of the CPU 51. The control circuit 52 for controlling the liquid crystal driver 12 to cause the liquid crystal display panel 11 to perform display corresponding to each operation mode, or for performing processing in each operation mode in the time counter 33 described later, a control program, and A ROM 53 that stores control data and a RAM 54 that temporarily stores various data are provided.
The pressure measuring unit 61 needs to measure and display the water depth (water pressure) in the dive computer 4 and calculate the amount of inert gas (mainly nitrogen gas) accumulated in the user's body from the water depth and the diving time. Therefore, atmospheric pressure and water pressure are measured. The pressure measuring unit 61 controls the pressure sensor 34 constituted by a semiconductor pressure sensor, an amplification circuit 35 for amplifying the output signal of the pressure sensor 34, and analog / digital conversion of the output signal of the amplification circuit 35, and performs control. And an A / D conversion circuit 36 that outputs to the unit 50.

In the dive computer 4, the time measuring unit 68 outputs a clock signal having a predetermined frequency, and divides the clock signal from the oscillation circuit 31 in order to measure the normal time and monitor the dive time. And a time counter 33 that performs time-counting processing in units of one second based on the output signal of the frequency dividing circuit 32.
The acceleration measuring unit 70 detects an acceleration, an amplification circuit 72 for amplifying the output signal of the acceleration sensor 71, and analog / digital conversion of the output signal of the amplification circuit 72, and sends it to the control unit 50. And an A / D conversion circuit 73 for outputting.

FIG. 4 is a sensor structure schematic diagram of a differential capacitor type sensor used as the acceleration sensor 71. FIG. 5 is a partially enlarged view of the differential capacitor type sensor in a state where no acceleration is applied.
The acceleration sensor (differential capacitor type sensor) 71 is, for example, a biaxial acceleration sensor, and has a first sensitivity axis LX1 and a second sensitivity axis LX2.
In the acceleration sensor 71, each tether 132 having flexibility is supported by a pair of fixed shafts 131. The pair of tethers 132 support the beam 133 from both sides.
Each beam 133 is provided with an electrode 133A projecting laterally, and each beam 133 is fixed at a position having substantially the same distance from each fixed outer electrode 134A, 134B with respect to the pair of fixed outer electrodes 134A, 134B. It is held so as to face the outer electrode 134.
Thereby, the electrode 133A and the fixed outer electrodes 134A and 134B each function as a capacitor having substantially the same capacitance.
FIG. 6 is a partially enlarged view of the acceleration sensor in a state where acceleration is applied.

In the state shown in FIG. 5, when the acceleration sensor 71 is tilted, the tether 132 bends due to the gravitational acceleration, resulting in the state shown in FIG.
As a result, for example, as shown in FIG. 6, the distance G1 between the electrode 133A and the fixed outer electrode 134A is larger than the distance G2 between the electrode 133A and the fixed outer electrode 134B. That is, the capacitance of the capacitor formed by the electrode 133A and the fixed outer electrode 134B is larger.
Therefore, since the generation period of this capacity difference is proportional to the acceleration detection period, it is possible to detect the acceleration period.
In addition, since it is proportional to the magnitude of acceleration, that is, the tilted angle, it is possible to detect the magnitude of acceleration by measuring the capacity difference.

The temperature measurement unit 80 detects the temperature, an amplification circuit 82 for amplifying the output signal of the temperature sensor 81, and analog / digital conversion of the output signal of the amplification circuit 82. And an A / D conversion circuit 83 for outputting.
The communication device 90 is an ultrasonic transmission unit for notifying an external device such as a dive computer attached to another diver that an abnormal state has occurred in the diver wearing the dive computer 4. It has.

Next, the configuration of the display unit will be described in detail with reference to FIG.

In the present embodiment, an example in which the display surface 11A is circular has been described, but the display surface 11A is not limited to a circular shape, and may be another shape such as an elliptical shape, a track shape, or a polygonal shape.

In the diving mode, the surface mode (time display mode), the planning mode, and the log mode, the decompression-free dive time, the water surface rest time, The temperature and the dive end time (maximum depth water temperature) are displayed.

A display unit 103 is provided.

When the diving mode is in a reduced pressure diving state, nitrogen gas (inert gas) tends to be absorbed or discharged. An area indicating whether or not (up and down arrows are shown in the figure), an area displaying “SLOW” for instructing deceleration as one of the ascent warnings when the ascending speed is too high, and diving And an area for displaying “DECO” for warning that decompression diving must be performed.

Next, the operation of the embodiment will be described.
Prior to detailed description of the operation, the outline operation will be described.
In the present embodiment, if there is an output from the acceleration sensor, the frequency is confirmed, and processing is performed by dividing it into a relatively low frequency and a relatively high frequency.
That is, it is determined whether or not a panic state is present at a relatively low frequency, and whether or not a tremor associated with heat loss is occurring at a relatively high frequency.
When an acceleration with a relatively low frequency is detected, the magnitude of the acceleration is confirmed, and when detection of an acceleration with a certain level or more is repeated, it is determined that the state is a panic.
If acceleration at a relatively high frequency is detected, if this state continues for a certain time or more, it is determined that a tremor of heat loss has occurred.
Then, notification and warning processing are performed based on each determination.

This will be described in more detail below.
FIG. 7 is a processing flowchart of the embodiment.
First, the CPU 51 determines whether or not the dive mode is set (step S11).
If it is determined in step S11 that the dive mode is not set (step S11; No), a standby state is entered.
In the determination of step S11, when the dive mode is set, the CPU 51 detects when the acceleration component corresponding to the tremor at the time of heat loss is detected and the user who is the diver is in a panic state. A panic counter CNTp that counts when an acceleration component of the motion to be detected is detected is initialized (step S12).
That is,
CNTt = 0
CNTp = 0
And

Subsequently, the CPU 51 determines whether or not the output of the acceleration sensor has been detected (step S13).
If the output of the acceleration sensor is not detected in the determination in step S13, the CPU 51 shifts the process to step S12 again and enters a standby state.
If it is determined in step S13 that the output of the acceleration sensor is detected, the CPU 51 calculates a period T of the detected acceleration (step S14).
Subsequently, the CPU 51 determines whether or not the calculated period T satisfies the following equation (step S15).
2 [sec] ≧ T ≧ 0.5 [sec]

In the determination of step S15,
T> 2 [sec]
Or
0.5 [sec]> T
(Step S15; No), the CPU 51 determines that the calculated period T is
0.5 [sec]> T
It is determined whether or not (step S16).

In the determination of step S16, the calculated period T is
T> 2 [sec]
If it is determined that the detected acceleration is NO (step S16; No), it is determined that the detected acceleration is noise-like, and the CPU 51 proceeds to step S12 again, and thereafter performs the same processing.
In the determination of step S16, the calculated period T is
0.5 [sec]> T
If it is determined that the detected acceleration is (step S16; Yes), since the detected acceleration is likely to correspond to the tremor caused by the heat loss, the CPU 51 sets the value of the heat loss counter CNTt. Count up by one (step S17). That is,
CNTt = CNTt + 1
And

Next, the CPU 51 determines whether the value of the heat loss counter CNTt is greater than 20, that is,
CNTt> 20
It is discriminate | determined whether it is (step S18). This is because if the value of the heat loss counter CNTt is greater than 20, it is estimated that tremors due to heat loss have occurred.
In the determination of step S18,
CNTt> 20
If it is (step S18; Yes), the CPU 51 determines that it is in a heat loss state, performs a notification and a warning via the sound reporting device 37, the vibration generating device 38, and the display unit 10, and ends the process. (Step S19).

Specifically, the sound reporting device 37 notifies that an abnormality has occurred by using a buzzer sound or the like. In addition, the vibration generator 38 notifies that an abnormality has occurred by vibration. Furthermore, the display part 10 displays that it is in a heat loss state.
Furthermore, the communication device 90 notifies other divers (instructor, buddy, etc.) that the diver is in a heat loss state by ultrasonic communication. As a result, the sound reporting device 37 of the dive computer 4 of another diver notifies that an abnormality has occurred in the other diver by a buzzer sound or the like. Further, the vibration generating device 38 of the dive computer 4 of another diver notifies the fact that an abnormality has occurred in the other diver by vibration. Further, the display unit 10 of the dive computer 4 of another diver displays that the other diver is in a heat loss state. In this case, if identification data for identifying each dive computer is assigned in advance, and display data is associated with the identification data, a display (number, Name).

In the determination of step S15,
2 [sec] ≧ T ≧ 0.5 [sec]
When it is determined that it is (step S15; Yes), the CPU 51 determines whether or not the detected acceleration is 0.5 G or more (step S20).
If it is determined in step S20 that the detected acceleration is less than 0.5 G (step S20; No), the CPU 51 determines that the detected acceleration is associated with the movement of a normal diver. Then, the process shifts again to step S12, and the same process is performed thereafter.

When it is determined in step S20 that the detected acceleration is 0.5 G or more (step S20; Yes), the detected acceleration is highly likely that the diver who is the user is in a panic state. Therefore, the CPU 51 increments the value of the panic counter CNTp by 1 (step S21). That is,
CNTp = CNTp + 1
And
Next, the CPU 51 determines whether the value of the panic counter CNTp is greater than 10, that is,
CNTp> 10
It is discriminate | determined whether it is (step S22). This is because, when the value of panic CNTp is larger than 10, it is estimated that the diver is performing an action of flapping the arm due to the panic.

In the determination of step S22,
CNTp> 10
If it is (step S22; Yes), the CPU 51 determines that the diver is in a panic state, performs a notification and warning via the sound reporting device 37, the vibration generating device 38, and the display unit 10, and ends the process. (Step S19).
Specifically, the sound reporting device 37 notifies that an abnormality has occurred by using a buzzer sound or the like. In addition, the vibration generator 38 notifies that an abnormality has occurred by vibration. Further, the display unit 10 displays that the diver is in a panic state.

  Furthermore, the communication device 90 notifies other divers that the diver is in a panic state by ultrasonic communication. As a result, the sound reporting device 37 of the dive computer 4 of another diver notifies that an abnormality has occurred in the other diver by a buzzer sound or the like. Further, the vibration generating device 38 of the dive computer 4 of another diver notifies the fact that an abnormality has occurred in the other diver by vibration. Further, the display unit 10 of the dive computer 4 of another diver displays that the other diver is in a panic state. Even in this case, it is possible to perform display for specifying a diver on the display unit 10 of the dive computer 4 of another diver by the method described above.

As described above, according to the present embodiment, when a tremor due to heat loss occurs in a state in which the diver cannot perceive itself, or when the diver falls into a panic state, that fact is indicated. Alternatively, since other divers can be notified, it is possible to take immediate action.
In the above description, when the value of the heat loss counter CNTt is larger than a predetermined value (20 in the above description), it is determined that the heat loss state exists, and the sounding device 37, the vibration generating device 38, and the display unit are determined. 10 is configured to perform notification and warning, but when the value of the heat loss counter CNTt is larger than a predetermined value and the ambient temperature tends to decrease, it is determined to be in a heat loss state. Is also possible.

FIG. 8 is a processing flowchart of a modification of the embodiment.
FIG. 8 differs from FIG. 7 in that step 25 for determining the change tendency of the diver ambient temperature is provided between step S18 and step S19. Only the main operation will be described below.
In this modification, the CPU 51 determines whether the value of the heat loss counter CNTt is greater than 20, that is,
CNTt> 20
It is discriminate | determined whether it is (step S18).
In the determination of step S18,
CNTt> 20
If so (step S18; Yes), the CPU 51 determines whether or not the ambient temperature tends to decrease based on the output signal of the temperature sensor 80 (step S25).

If it is determined in step S25 that the ambient temperature does not tend to decrease, that is, if the ambient temperature tends to increase (step S25; No), there is a high possibility that the heat loss state will not be reached, and the process is terminated.
If the ambient temperature tends to decrease in the determination in step S25 (step S25; Yes), the CPU 51 determines that the heat loss state exists, and the sounding device 37, the vibration generator 38, and the display unit 10 are turned on. Notification and warning are made through the process, and the process is terminated (step S19).

  Even in this modification, when a tremor due to heat loss occurs in a state where the diver is not perceivable by the diver, or when the diver falls into a panic state, the fact is notified to the diver or other diver. It is possible to take action as soon as possible.

Further, in the above description, the case where the ecological information monitoring apparatus is configured as a dive computer has been described. However, when activities or work are performed in a low temperature environment, for example, climbing (especially winter mountain climbing), in a freezer Even if the person himself / herself is not aware of the tremor during work, the situation can be grasped while the heat loss state is light, and the necessary response can be taken early. Also, it is possible to notify other workers or the like of the heat loss state by communication using a communication device (in this case, communication using radio waves, light, etc.) and make it correspond.
In the above description, the detected acceleration period T is used in the processing in the CPU 51. However, it is also possible to perform the same processing using the frequency.

  In the above description, the case where the control program for controlling the dive computer is stored in the ROM in advance has been described. However, the control program is recorded in advance on recording media such as various magnetic disks, optical disks, and memory cards, It is also possible to read and install from these recording media. It is also possible to provide a communication interface and download the control program via a network such as the Internet or LAN, and install and execute the program. By configuring in this way, it becomes possible to configure a dive computer with higher functionality in terms of software and higher reliability.

In the above description, the case where the acceleration sensor is a biaxial differential capacitor type sensor has been described. However, other types of acceleration sensors may be used. For example, a plurality of uniaxial acceleration sensors may be provided, or a triaxial piezo acceleration sensor may be used. In other words, regardless of the type and number of acceleration sensors, any acceleration sensor can be applied as long as it can detect the acceleration associated with the user's tremor or panic movement. However, considering that the dive computer is a portable device, lower power consumption is more preferable.
In the above description, the acceleration sensor is built in the dive computer main body. However, the acceleration sensor may be provided outside the dive computer main body.
FIG. 9 is a diagram illustrating an external configuration of a dive computer according to a third modified example, together with an aspect of its use.

In the dive computer main body 4XA, the upper case and the lower case are fixed by a method such as screwing in a completely watertight state, and various electronic components (not shown) are incorporated. Further, the dive computer main body 4XA is provided with a display unit 4XG having a liquid crystal display panel.
Further, an acceleration detection signal is input from the acceleration sensor unit 4XE via the cable 14 to the connector portion 14XC provided on the outer peripheral portion in the 6 o'clock direction of the dive computer main body 4XA.
Since the operation is the same as that of the embodiment, the detailed description is omitted.
In the above description, when the CPU 51 determines the calculated period T, 2 [sec] and 0.5 [sec] are used as determination criteria. However, these are examples and can be set as appropriate. Is possible.
In the above description, the case where the ecological information monitoring apparatus is an arm-mounted type is described. However, the present invention is not limited to this, and clothing (diving suit) can be used as long as acceleration due to a heat loss state or a panic state can be detected.
