DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic water depth measurement portable device suitable for recording an activity of a diver during a dive operation.

[0002]

2. Description of the Related Art In recent years, with the development and spread of diving equipment, the diver population has rapidly increased, and not only professional divers,
Conventionally, people who have enjoyed skin diving without Aqualung have started scuba diving using Aqualung. This so-called amateur diver actually dives after learning correct usage of diving equipment, diving knowledge, precautions during diving, etc. at a driving school or the like.

However, since a diver does not have any means to verify how he / she actually dive and how he / she dive as planned, even a dangerous dive cannot be noticed. That is the reality.

[0004] Furthermore, professional divers cannot be said to be diving based on diving knowledge, and diving illness does not end every year. In addition, in the treatment of a person who suffers from sickness, there is a situation in which proper treatment cannot be carried out because the past of sick divers and accurate diving records at the time of sickness are not recorded.

In order to solve this problem, an electronic depth measurement portable device for automatically storing a dive depth corresponding to an elapsed dive time has been invented.

A conventional diving portable device is disclosed in
As shown in JP-A-101736, a water depth information generating means for sensing water depth and outputting water depth value information, a presetting means for setting and storing a water depth value, and a water depth value of the water depth information generating means being larger than the storage unit. An electronic timepiece with a depth gauge is provided with a comparison circuit for comparing the depth and issuing an alarm signal, and an alarm generating means, which alerts a diver to a dangerous depth by a buzzer sound when the preset depth is reached.

However, in an actual diving operation, the electronic timepiece with a depth gauge which merely informs a diver of a preset water depth as a danger depth is not safe and the diver cannot dive with peace of mind.

[0008]

In view of the above, from the viewpoint of safety, it is necessary to analyze and evaluate the dive depth corresponding to the elapsed dive time for the dive work performed by the diver to determine the necessity of treatment and the like. However, heretofore, there have been few portable devices provided with a diving recording function necessary for predicting or treating such diving diseases, which has been a serious problem for divers.

In view of the above, according to the present invention, an electronic water depth measurement system capable of recording a dive latency corresponding to a dive elapsed time when a diver performs a dive operation, and displaying or recalling the recorded content after the end of the dive operation. It is an object to provide a portable device.

[0010]

Next, the operation of the electronic water depth measurement portable device of the present invention based on the above configuration will be described.

First, when the diver presses the external setting means 2a when starting the dive, the switch control circuit 11 is activated and the control circuit 8 instructs the depth measurement by the dive depth sensor, and the dive depth sensor 6 and the depth measurement circuit 7 starts operation. At the same time, the control circuit 8 resets the time counting circuit 5 and issues a dive elapsed time counting start command to start the operation. Then, the measured dive depth information and the dive elapsed time information are taken into the control circuit 8 and displayed on the display device 3 through the display drive circuit 10 as shown in FIG.

In general, measurement sampling is measured every one or two seconds and the result is displayed.

Next, assuming that the dive is performed as shown in FIG. 2, the actually measured dive depth information and the dive elapsed time information are sequentially displayed by the operation described above. Here, the control circuit 8
Automatically takes in the information of the time counting circuit 5 and the water depth measuring circuit 7 every time the diving elapsed time has elapsed for 5 minutes, and stores it in the diving information storage circuit 9. 4a, 4b, 4c, shown in FIG.
Information on points 4d and 4e. When the dive ends, the diver presses the external setting means 2a. Then, the switch control circuit 11 operates to stop the operations of the diving depth sensor 6 and the water depth measuring circuit 7, and at the same time stops the operation of the time counting circuit 5 and stores the dive elapsed time at the end of diving in the diving information storage circuit 9. This is point 4f shown in FIG.

By the operation of the external setting means 2a, the external setting means 2b is released from the input prohibition state, and is set to the input enabled state.

In this state, when the external setting means 2b is depressed, the switch control circuit 11 operates to call the diving information from the diving information storage circuit 9 by the control circuit 8, and the display driving circuit 10
Through the display device 3. This display is the information of 4a shown in FIG. Next, from this state, the external setting means 2b
When the is pressed one after another, diving information is called one after another as shown in FIG.

As described above, the present invention sets the elapsed dive time every 5 minutes and stores the actually measured dive depth in the present embodiment. Alternatively, the actually measured diving depth may be stored every two minutes. Furthermore, the average dive time of the diver may be set every 5 minutes within 1 hour, and every 10 minutes after 1 hour, based on 1 hour. This may be determined based on the scale of the dive information storage circuit 9 and practical use, but in practice, 5 minutes is sufficient, and if a dive curve of 4 h is drawn as shown in FIG. Thus, the data for treatment of divers in the unlikely event will be satisfactory.

Each time the external setting means 2b is pressed once, the display is switched between 4a, 4b, 4c,..., And when the external setting means 2b is continuously pressed, the display is automatically switched to 4a, 4b, 4c.
The display may be switched as c ...

Further, the state of 4g shown in FIG. 2 is stored in a part of the dive information storage circuit 9 by the control circuit 8 with the actually measured dive depth and elapsed dive time taken for each measurement sampling, and stored.
When the next dive depth and dive elapsed time are taken in, the dive depth which is larger than the previous dive depth and the dive elapsed time at the time of the measurement are stored.

If this repetition is performed and the maximum dive depth and the dive elapsed time at that time are stored in the dive information storage circuit 9 and recalled, more accurate information close to the actual one can be obtained.

In the embodiment of the present invention, the stored diving information is called for display, but it may be connected to an external device and automatically printed out.
