Abstract

PURPOSE:To indicate a piece of information on safety after the end of dive by measuring a rest time on the water surface and indicating a flight impossible mark till a specific time passes or a dive impossible flag when the specific time reaches. CONSTITUTION:A CPU 23a judges it is a rest time on the water surface when the data of a water depth value from a pressure sensor 21 are phi and operates a rest time measuring counter B 25 to output its data thereto. A prescribed time previously written in a ROM 23b is compared with rest time data to output an ON/OFF signal of a flag to an LCD 26 depending on whether the rest time is within the prescribed time. Further, the rest time is subtracted from the prescribed time and the result is output to the LCD 26. Next, a flight time is output to a RAM 23c by outputting the ON/OFF signal of an outside input switch 27 to the CPU 23a. The prescribed time is subtracted from the flight time and a dive impossible flag is indicated in the LCD 26 when the remainder time is prior to a present time.

Description

[Detailed description of the invention]

[Industrial application field] The present invention relates to a diver's watch.

[Conventional technology 1] In addition to measuring water depth, conventional diver's watches measure the maximum depth, which is the value of the deepest dive, the diving time, or a depth alarm that warns with an audible sound when a certain diving time is exceeded. There is a growing demand for depth gauges that have the necessary functions for safe diving, such as a diving time alarm that warns when diving. [Issues that the invention aims to solve However, with such conventional diver's watches, although caution is taken regarding safety during each dive, safety after the end of the dive is not considered. It is said that you should not fly on a plane for 12 hours after diving.
If you are not careful, you may accidentally board a plane.Also, even if you are careful not to board a plane for 12 hours after diving, you may board a plane because you did not pay attention to the flight time during the dive. One issue was that there were times when it became impossible to do so. The present invention was made in view of these problems, and its purpose is to measure the resting time, which is the time spent resting on the water surface after the end of a dive, and to prevent flights from taking place until 12 hours have elapsed. The objective is to provide a diver's watch that takes safety into consideration after diving by displaying a flag or a flag indicating the time until flight is possible, and a no-dive flag 12 hours before the flight time. . [Means for Solving the Problems] In order to solve the above problems, the diver's watch of the present invention, as shown in the functional block diagram 6 of FIG. a diving surfacing signal means 11 for measuring the diving time according to the diving surfacing signal; , a rest time measuring means 13 for measuring the time spent resting on the water surface, and a control means 12 for outputting a signal for operating the diving surfacing signal means and the resting time measuring means according to the diving surfacing signal. , a storage means 18 for setting and storing a time using the external input means; and a detection means for detecting whether the measured rest time data is within a specified time using the rest time measuring means;
a detection means 14 for detecting the time up to a specified time; a comparison means 19 for comparing the time stored in the storage means with the current time; and a display for displaying the result of the detection means signal and the result of the comparison means. means 16. [Example] Therefore, details of the diver's watch of the present invention will be described below based on an illustrated example. FIG. 2 shows an embodiment of the diver's watch of the present invention. In the figure, numerals 21 and 22 are diving surfacing signal means, and numeral 21 is a diaphragm type semiconductor pressure sensor, which responds to the depth of the water. Outputs the signal. 2.2 is A/
The D converter is controlled by the CPU 23a, which will be described later, at a predetermined period to A/D convert the output signal of the pressure sensor 21 into a digital water depth value.
Output to U23a. 23 is a micro combination, which is a control (distribution means. CPU 23a, ROM 23b, R
It is composed of AM23c. ROM23b contains C
Program data for controlling the PU 23a is written, and the CPU 23a controls the A/
By controlling the D converter 22, data is output to the LCD 26 as necessary while taking in digital water depth values and exchanging data with the RAM 23c. If the water depth value data is not φ, the CPU 23a determines that
It is determined that the diver is diving, and the counter A24 for measuring the diving time is activated.

data is output to the CPU 23a. Further, if the water depth value data is φ, the CPU 23a determines that the fish is resting on the water surface, operates the counter of the rest time measuring counter B25, and outputs the data of the counter B25 to the CPU 23a. The CPU 23a compares the specified time written in advance in the ROM 23b with the rest time data from the counter B25, detects whether the rest time is within the specified time, and turns the ON/OFF signal of the flag on the LC based on the detection result.
Output to D26. Further, the CPU 23a subtracts the rest time from the specified time and outputs the result to the LCD 26. Reference numeral 27 in the figure is an external input switch, which sets the flight time by outputting an ON/OFF signal of the external input switch to the CPU 23a, and transmits the set time to the RA.
Output to M23c. From the set flight time, the ROM23b
The specified time written in is subtracted by the CPU 23a,
If the subtracted time is before the current time, a diving prohibition flag is displayed on the LCD 26. FIG. 3 is a flowchart showing how the diver's watch of the present invention is operated. The explanation will be based on the flowchart. First, input and output signals to import necessary information from the A/D (Step 1), input digital water depth value data from the A/D (Step 2), and convert the input digital data into water depth values. (Step 3). Based on the data converted to the water depth value, it is determined whether or not the user is diving (Step 4), the diving time is counted from IU ice water (Step 5), and the water depth and diving time are displayed (Step 6). If you are not diving, count your rest time in step 7.
), Compare the rest time with the specified time (Step 8), If the rest time is greater, display the no-flight mark (Step 9); If the rest time is smaller, display the N9 flight mark (Step 10), The rest time is subtracted from the AU fixed time (Step 11), and the time until the specified time is displayed (Step 12). Next, subtract the specified time from the flight time (step 1.3), determine whether the current time is after the subtracted time (step 14), and if it is after, it is determined that diving is not possible, and tide water is not allowed. A flag is displayed (step 15). [Effects of the Invention] As explained above, according to the present invention,
It is said that you are not allowed to board a plane for 12 hours after the rootstock is removed, but if you do not take any precautions after diving, you may accidentally board the plane, whereas the rest time on the water surface is 0 hours. 1
fll11. ．． ．． Until 12 hours have elapsed, by displaying a mark indicating that you cannot fly or displaying the time until you can fly, you may accidentally inadvertently display a mark that indicates that you cannot fly until 12 hours have elapsed.
You can prevent yourself from getting on an airplane, and you can safely scuba dive. You can also set the flight time in advance.
12 hours before the flight time, by displaying the no-dive flag 1. For example, if you have just skiuba-dived without worrying about the flight time, when it is time to board the plane, the no-flight flag will be displayed. This will prevent you from being unable to board a plane due to the display remaining on the screen, allowing you to dive more systematically, which will have a great effect on the commercialization of diver's watches. .
