In particular, the communication unit 600 preferably includes a Bluetooth module, which is a short-range wireless communication, and is provided to transmit and receive data through a Bluetooth communication method with a smartphone of a user.

As shown in FIG. 4, the user can create a desired sentence while being paired with the diver pad and Bluetooth. Then, a sentence created by the user is transmitted to the diver pad as shown in FIG. 5, and can be registered in the numbered list as shown in FIG.

In this way, the data transmitted by the user using the external terminal is stored in the automatic display storage 700. When the user inputs a number or selects a sentence, the display unit displays the stored contents.

When the user starts diving, the water depth is measured by the water depth sensor as shown in FIGS. 7 and 8, and the timer is activated, and the diving time is recorded. At the same time, the temperature is measured by the temperature sensor and displayed on the display unit. Further, in the control unit, the descent and the ascend are determined in accordance with the variation of the depth of water, and the descending speed and the ascending speed are calculated and displayed on the display unit, respectively.

On the other hand, referring to FIG. 9, the display mode can be converted into the direction mode, and when the mode is the direction mode, the moving picture of the north, south, east, and west is displayed on the middle screen. In other words, 0 degrees in the north, 90 degrees in the east, 180 degrees in the south, and 270 degrees in the west are displayed, and 0 to 359 degrees are displayed according to the user's progress direction.

The direction of the user's progress and the direction of the destination can be displayed in different colors. For example, in FIG. 9, the user's progress direction is displayed in red, and the destination is displayed in blue. In FIG. 9, it can be seen that the user is proceeding to the north and the destination is the northeast direction. The destination can be a number from 0 to 359 degrees.

On the other hand, referring to FIG. 10, the display depth and corresponding characters can be stored in the automatic display storage unit. When the display depth and corresponding characters are stored, the depth sensor measures the depth of the water in the actual diving, and if the measured depth data is measured to match the display depth, the control unit displays the corresponding character on the display unit. Accordingly, the user can automatically display a character to be displayed in accordance with the diving process without operating the diver pad. However, the indication of the dive process can be used to prepare for diving time and diving process by analyzing the statistical information stored in the diver pad.

The automatic display storage unit stores contents to be divided into education, emotion, and emergency mode, and the control unit displays contents on the display unit in different modes for each mode.

Specifically, in the education mode, the contents to be taken by the divers are stored according to the depth of the water, and the contents of education are stored according to the descent and the ascension. When diving in the training mode, the control unit displays the corresponding training contents through the display unit according to the depth data by the depth sensor.

Also, in the emotion mode, the contents created and stored by the user are displayed, and the user can display the created contents one after another by pressing the up / down button or the next button.

The emergency mode is switched to the emergency mode when the control unit determines that the emergency situation is present, and displays the alarm signal through the display unit.

The emergency situation is set in advance so as to be judged as an emergency situation when a threshold value is reached using an acceleration sensor, a timer, or the like. That is, when the acceleration by the acceleration sensor exceeds the critical acceleration, the control unit activates the timer. If the critical acceleration exceeds the predetermined time (for example, 3 seconds), the control unit judges the emergency situation. In addition, the control unit displays the button alarm through the display unit for every button alarm cycle (for example, five minutes), and judges the emergency situation when there is no button operation for a preset threshold time after the button alarm is displayed.

It is preferable that the button alarm cycle is changed according to the depth of water, and the button alarm cycle is shortened as the water depth is deepened.

After completing the diving, the number of dives is increased by one in the diver pad and stored in the storage unit. In the present embodiment, when the number of diving is five or less, the diver's authority is stored as "trainee" and the limit diving depth is set to 18m.

When the user starts to dive, the contents of the diver pad are displayed on the display unit according to the order of the stored curriculum. At this time, the controller checks whether there is a violation in the stored regulation, and if there is a violation, displays the corresponding content on the display unit. In other words, if the previous diving information is read and the previous diving is performed 18 hours before, and the rest time is required for 24 hours, the control unit checks the diving time, subtracts the immediately preceding dive time from the prescribed break time, I will.

Also, if the diver dives in excess of 18m in a state where the diver's authority is stored as " trainer ", the controller emits a red LED light and displays a warning message if it is determined that the depth is exceeded by the depth sensor. On the other hand, if it is determined that the depth is not exceeded, the control unit emits green LED light to indicate that it is in a normal state.

Meanwhile, the control unit changes the diver authority according to the number of dives of the user, and the limit diving depth is newly set for each changed diver authority.

Diving training is divided into deep dive specialty training, technical training, and midnight diving training. These courses are stored in the dive information for a specific dive.

If the diving depth is less than 40m, the control unit emits a green LED light to indicate that it is in a normal state. However, if it is determined that the diving depth by the depth sensor exceeds 40m It emits a red LED light and displays a warning message.

Also, if the dive time is less than 18 o'clock and less than 9 o'clock the next morning, if the dive operator is not in the middle of the night dive training, the control unit emits a red LED light and displays a warning message.

The diver pads use a depth sensor to guide the user to stay in the diving area for a certain period of time when the user reaches the target depth according to the diving plan. For example, if the target depth is 50m, the range of diving can be set to 45m ~ 55m. If the target depth is reached, the control unit activates the timer to measure the target depth diving time. In addition, if the maximum depth of water reaches 55m and the minimum depth of water reaches 45m within the target depth diving time, the control unit displays a warning message on the display unit.

When the target depth diving time is reached by the timer, the control unit displays the rising guidance on the display unit. At this time, the control unit measures the ascending speed, and displays a warning message on the display unit when the ascending speed is higher than the reference speed. For example, the reference speed may be set to 18 m / min, and if the rising speed is greater than the reference speed, the control unit displays a warning message on the display unit.

The control unit detects the depth of the water in the ascending stop section, displays the rising stop message on the display unit, activates the timer, measures the rising stop time do. The rising stop time is also set in advance, and when the rising stop time is reached, the controller displays a rising message on the display unit.

On the other hand, in the rising stop section, the mixing ratio of the air tank corresponding to the water depth is determined, and the controller guides the mixing ratio of oxygen and nitrogen in the air tank corresponding to the water depth to be changed.

In this way, the user is guided by the diver pad to prevent safety accidents such as nitrogen poisoning, and has the advantage of being able to perform safe diving activities.

After diving, all the diving information is stored in a database as shown in FIG. 11, and the diving information can be transmitted to an external terminal or server such as a smart phone.

On the other hand, the statistical analysis unit 900 analyzes and evaluates the user's diving information after finishing the predetermined training period. The statistical analysis unit may be embedded as a software module.

12 and 13, the statistical analysis unit evaluates whether each item is performed or not by using the diving information during the education period of the user, and scored. For example, statistically analyze the dive information during two months of training, extract the four occurrences of the rising warning, and generate and store the corresponding score.

At this time, items to be evaluated by the statistical analysis section include the maximum depth, the diving range, the rising warning, the break time, the diving time, the target depth diving time, Here, the dive time means the time from the beginning of diving to the time of going up to the surface of the water.

The statistical analysis unit compares each item with a reference value and evaluates the violation status and the degree of violation. That is, the reference value is determined for each item, and the difference between the data and the reference value for each item is calculated, and the score is calculated based on the difference between the item data and the reference value.

Specifically, referring to the diving information in FIG. 12, the maximum depth reference value is 55 m in the maximum depth item, so that the reference value difference is calculated as shown in FIG. 13, and the statistical analysis unit determines that the reference value difference is negative. Also, in case of non-violation, the score is stored as the maximum score of 10 points, and in case of violation, the score of the maximum score and the difference of the reference value is stored.

In this way, scores are stored for each number of dives, and when the course is over, the arithmetic average score of each number of times is calculated as the item score of that item. That is, in this embodiment, the maximum depth item score is calculated and stored as 9.1.

In the case of the diving range item, the reference value is set to 45m to 55m, the number of times when the range is out of range can be counted as the violation, and the score can be calculated based on the number of violations, the range outside, and the time outside.

Other items can be scored in a similar way.

On the other hand, in the statistical analysis section, if the number of violations is more than the number of violations for each item, the score is not calculated and it is judged to be eliminated. The number of violations of the standard can be set for each item. For example, the number of violations can be set to 3 times for the maximum depth, and the number of violations to the standard for the diving range can be set to 5 times.

When the score of each item is calculated, the statistical analysis unit adds the score of each item as shown in FIG. 14, and if the score exceeds the passing score, the score is passed. Here, if accepted, they can move on to the next curriculum, and if they are rejected, they can repeat the same curriculum.

As described above, according to the present invention, not only the diving information of the user is displayed but also the information that can objectively determine how much the user accomplished the diving by summing up the respective data is provided, This is big.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, and variations and modifications may be made without departing from the scope of the invention. It will be understood that the present invention can be changed.
