Description

Diving watch with diving warning function

The present invention relates to a computer watch, especially to a computer watch with diving warning function.

Leisure diving refers to diving activities for entertainment and leisure purposes. The maximum diving depth is usually not more than 30 meters underwater. Before diving, the diving plan must be set according to the decompression theory. This is because various tissues in the body will absorb and emit nitrogen in a predictable manner. Generally, the nitrogen content of each tissue in the human body is 0. When the environmental pressure increases, all tissues in the body will begin to absorb nitrogen. Since the human body does not consume nitrogen, when the diver starts to rise, the nitrogen absorbed in the body will come from each tissue. It drains to the blood and flows to the lungs, and leaves the body in every expiratory cycle.

Theoretically, as long as the nitrogen content in the tissue does not exceed the no-decompression limit, divers can return to the surface with a safe ascent rate without getting decompression sickness, commonly known as diving sickness. However, as the depth of the dive is deeper and the time is longer, the nitrogen content in the tissue may exceed the no-decompression limit. At this time, the diver has no way to return directly to the water surface with a safe ascent rate, but must be in the process of ascent. Especially after staying at a certain depth under the water surface for a period of time, the nitrogen content in the tissue gradually decreases with the exhalation cycle to below the no-decompression limit before returning to the water surface, otherwise you will get decompression sickness, and This process of staying under the water is called decompression stay.

Since the definition of leisure diving does not allow decompression stops, the itinerary of the leisure diving plan must be calculated throughout the diving plan, and the nitrogen content in the body tissue will not exceed the no-decompression limit. Although the general amateur divers will be guided by the dive guide during the leisure dive, it is inevitable that divers and divers will be interested in different water objects at different depths, or the diver and team will be separated. At this time, in order to Do follow the diving plan to perform diving tasks, an auxiliary device that can remind the no-decompression limit time is needed.

In view of this, the main purpose of the present invention is to provide an auxiliary device that can remind the decompression limit time.

In order to achieve the above object, the present invention provides a diving watch with a diving warning function, which includes a watch case, a display, a depth gauge, a timer and a processor. The display, depth gauge, timer and processor are all Set in the watch case, the depth gauge is used to sense the diving depth, the timer is used to sense the diving time, the processor is electrically connected to the display, the depth gauge and the timer, and the processor is used to measure the diving depth according to the diving time and the depth gauge Obtain the remaining no-decompression limit time at the depth of the diving watch, and the display is used to display the no-decompression limit time. In this way, divers can clearly know how long they can stay underwater without decompression stops, so as to maintain the safety of diving activities and follow the itinerary of the leisure diving plan for leisure diving.

Please refer to FIGS. 1 to 4, which is one of the embodiments of the new diving watch. The diving watch includes a watch case 10, a display 20, a depth gauge 30, a timer 40, a process 50, a first charging interface 60, a charging clip 70, and a battery 80 for supplying power.

The display 20 is provided on the watch case 10 and can display one or more user interfaces and display diving information required for diving.

The depth gauge 30 is provided on the watch case 10 and used to sense the diving depth. In this embodiment, the depth gauge 30 is a temperature-compensated pressure sensor, that is to say, the sensor can measure the diving temperature and pressure at the same time, and Correct the pressure compensation according to the measured temperature to convert the diving depth. For sensing, a part of the depth gauge 30 is exposed from the outer surface of the watch case 10.

The timer 40 is set in the watch case 10 and is used to sense the diving time and as a timing standard for other timing-related functions. For example, the timer can be a quartz oscillator.

The processor 50 is set in the watch case 10 and electrically connected to the display 20, the depth gauge 30 and the timer 40, and the processor is used to obtain a depth under the diving watch according to the diving time and the diving depth sensed by the depth gauge The remaining no-decompression limit time. In a possible implementation manner, the aforementioned decompression-free limit time calculation model adopts 16 tissue chamber compartment models developed by Bühlmann, and the half-time tissue table adopts the Bühlmann ZH-L16C standard to perform calculation according to the decompression algorithm. After the processor 50 obtains the no-decompression limit time, the display 20 can display the no-decompression limit time, and can provide a warning when necessary.

On the other hand, in order to charge the diving watch, the back of the watch case 10 further has a first charging interface 60, and the charging clip 70 has a pair of jaws 71, 72 and a second charging interface 73, the second charging interface 73 It is provided on the side (ie, the inner side) of one of the jaws 71 facing the other jaw 72. During charging, the pair of jaws 71, 72 clamps the watch case 10 so that the second charging interface 73 located inside the jaw 71 and the The first charging interface 60 on the back of the watch case 10 contacts and forms an electrical connection. The charging clip 70 may be additionally connected with a power cord to connect to an external power source, so as to charge the battery 80 in the watch case 10.

The following describes how to use the diving watch according to one embodiment of the present invention through several user interfaces presented on the display 20.

Please refer to Fig. 5, the picture shows a user interface of water surface preview, which can provide various diving parameters and information before diving for divers' reference; 1008 mBAR is the ambient atmospheric pressure at the current location; SF% It is a conservative degree that can be set by the user, for example, it can be divided into normal (NORM), conservative (CONS) and less conservative (AGGR); PPO2 is the limit value of oxygen partial pressure, which is allowed by the user. Value, for example, can be set between 1.2-1.6; O2% is the oxygen concentration of the gas used, which is a value set by the user, for example, it can be set between 21%-56%; MOD is the maximum allowable depth, is The processor calculates the maximum depth allowed for the user to dive according to the set PPO2 and O2%; TIME indicates the dive time.

Please refer to Figure 6, the one shown is one of the user interfaces during diving. The user interface can automatically jump out after the user dives a predetermined depth (for example, 1.5-3 meters), which can provide dive time. The various diving parameters and information for the diver's reference; of which, 018.6m is the current depth; NDL is the remaining no-decompression limit time at that depth. When the remaining time is less than three minutes, it is displayed in seconds and the remaining time exceeds three In minutes, it is displayed in minutes; PO2 is the oxygen partial pressure of the gas used at the current depth; ︽ represents the ascent rate; TIME is the diving time; TEMP is the current water temperature.

Please refer to Figure 7. When the dive time exceeds the no-decompression limit time, the display will automatically jump out of the user interface shown in this figure; at this time, NDL shows that the dive activity exceeds the no-decompression limit time exceeded time, the exceeded time is insufficient At three minutes, it is displayed in seconds, and when the time exceeds three minutes, it is displayed in minutes; CEILING is the limit depth that the diver can directly reach after exceeding the no-decompression limit time.

Please refer to Figure 8. When the dive time exceeds the no-decompression limit time and the diver reaches the limitable depth, the display will automatically jump out of the user interface shown in this figure; at this time, STOP indicates that the diver reaches the limitable depth Time, it should stay at this limit depth of residence time.

Please refer to Figure 9, when the diver reaches the limit of ascending depth and the stop time is zero, it indicates that the stop is completed, then the display automatically jumps out of the user interface shown in this figure, where CLEAR indicates that the diver has completed the stop of the limit depth .

With the above design, divers can clearly know how long they can stay underwater without decompression stops during the diving process, so as to maintain the safety of diving activities and follow the itinerary of the leisure diving plan for leisure diving . In addition, even if the diving activity exceeds the no-decompression limit time, the diving watch of this embodiment may further provide information such as the diver's ascent limit depth and the stop time to stay at the limit depth, and prompts when the diver completes the decompression stop to ensure The safety of diving activities avoids or at least greatly reduces the problem of divers getting decompression sickness.
