Description

Technical Field

[0001] This invention relates to a device and method for monitoring and correcting the decompression process of divers during diving. Background Technology

[0002] During a dive, divers are affected by underwater environmental factors, especially hydrostatic pressure and low water temperature. They must use diving equipment and breathe compressed air to maintain a balance between their physiological state and environmental conditions. An imbalance can lead to illness and injury, collectively known as "diving sickness." Among these, decompression sickness has the greatest impact on a diver's health and safety. This occurs when a diver ascends (decompresses) to the surface after a certain depth and time, due to excessive speed or amplitude of ascent. It can potentially leave permanent health problems. Most diving sicknesses are caused by failure to comply with decompression regulations, lack of technical proficiency, or insufficient diving knowledge.

[0003] Based on practical experience and considering my country's specific circumstances, the Ministry of Transport system and naval diving medicine professionals and divers have developed decompression tables (12-60m) suitable for the physical condition of Chinese divers and the characteristics of Chinese sea areas. Table 1 shows the decompression tables for conventional air diving at depths of 12-24m. The time to ascend to the first stop is listed in the table, and the time to ascend to the next stop is set to 1 minute. From the table, we can calculate that, for a dive depth of 24m and an underwater working time of 45 minutes, the decompression time from 24m to the first stop at 6m is 3 minutes, followed by a 6-minute stay at the first stop (total decompression time = 3 + 6 = 9 minutes). The subsequent ascent to the 3m stop is 1 minute, followed by a 20-minute stay at the 3m stop, and finally a 1-minute ascent to the surface. The total decompression time is 3 + 6 + 1 + 20 + 1 = 31 minutes, consistent with the times in the decompression table.

[0004] The selection of a decompression plan is based on the provisions of GB 12521 and GB 26132. Before the end of underwater work, the diving supervisor or relevant technical personnel shall correctly select a decompression plan according to the diver's maximum underwater working depth, underwater working time, and individual factors, referring to the diving decompression table. The underwater decompression process is the process of decompression for the diver in the water, which is divided into ascent, pause, re-ascent, re-pause, until returning to the surface, at which point decompression ends. During the decompression process, in order to gradually expel supersaturated nitrogen from the body, the diver must stay at a specified depth for a certain period of time; the specified pause depth is called a pause station.

[0005] Table 1 Decompression Table for Conventional Air Diving (12-24m)

[0006]

[0007] Currently, decompression plans for divers are mainly formulated manually. After the dive is completed, the dive supervisor needs to time the dive while calling the diver via underwater telephone to obtain the maximum depth, and then formulate a decompression plan based on the decompression table. The current method of formulating decompression plans has the following problems: (1) The dive supervisor needs to check the dwell time of each station and level by referring to the decompression table, which requires high skill from the dive supervisor and requires a large amount of special training to be competent. If the dive supervisor's technical level is not high enough, it is easy to cause decompression sickness risk to the diver. (2) When the water is deep, the light is insufficient, or the water is turbid, the diver's underwater vision is poor and the depth gauge is not clear, which makes it easy to misjudge their own depth position. In addition, the dive supervisor on the surface cannot know the diver's depth position in real time. When calling the diver via underwater telephone to inquire about the depth position, it will interfere with the diver's work. (3) The time that the diver spends waiting for the decompression plan to be formulated increases the total underwater dwell time, which is a waste of time and inefficient. In addition, the probability of human error in emergency operations will also increase. (4) Surface diving supervisors cannot obtain the ascent time and dwell time of each diver at each stop, cannot effectively determine whether the diver is operating in accordance with the established decompression plan, and cannot make timely corrections when deviations occur, which poses potential safety hazards to the diver. Summary of the Invention

[0008] The first objective of this invention is to address the shortcomings of existing technologies by providing a device for monitoring and correcting the decompression process of divers, which automatically monitors the diver's diving and decompression process, formulates and corrects decompression plans, and guides the diver to complete the decompression process through voice broadcast.

[0009] Therefore, the above-mentioned objective of the present invention is achieved through the following technical solution:

[0010] A device for monitoring and correcting a diver's decompression process, characterized in that: the device includes a diving helmet, which is equipped with a depth sensor, a voice announcer, a camera, and a lighting lamp;

[0011] The water depth sensor is connected to the signal processing display via a first signal cable, and the voice broadcaster is connected to the signal processing display via a second signal cable.

[0012] The processing display is integrated with a processor, a timer, and a display via a power signal cable;

[0013] The processor identifies and retrieves the decompression table to formulate a decompression plan based on the diver's maximum water depth H and underwater working time T. The processor's strategy for retrieving the decompression table is as follows: (1) Since the decompression gradient diving depth column L1 in the diving decompression table is a multiple of 3, H is entered in the processor, K = H / 3 is calculated, the smallest integer K′ greater than K is returned, and P = 3 * K′ is calculated; (2) Since the time period of the underwater working time column L2 at each diving depth in the decompression table is not regular, the underwater working time at each diving depth is divided into intervals according to the time period. If the underwater working time T falls within a certain interval, the maximum value T′ of this interval is returned; (3) A decompression plan is formulated according to the row of the diving depth P and the underwater working time T′ in the decompression table.

[0014] The target ascent rate curve and the dwell time at each station in the decompression scheme are plotted continuously as solid lines on the real-time water depth monitoring graph on the display.

[0015] While adopting the above technical solutions, the present invention may also adopt or combine the following technical solutions:

[0016] As a preferred embodiment of the present invention: the first signal cable is used to transmit the data from the depth sensor to the processor in real time.

[0017] As a preferred embodiment of the present invention: the second signal cable is used to transmit the water depth data monitored by the processor to the voice broadcaster via an acoustic signal.

[0018] As a preferred embodiment of the present invention, the processor is provided with buttons for starting diving, starting decompression, and ending decompression.

[0019] As a preferred embodiment of the present invention: when the processor triggers the start diving button, the timer starts counting; when the decompression end button is triggered, the timer stops counting.

[0020] As a preferred embodiment of the present invention, the data processed by the processor and the time of the timer can be displayed on the display.

[0021] As a preferred technical solution of the present invention: the display interface shows the maximum diving depth, underwater working time, diving status and real-time water depth monitoring graph.

[0022] Another objective of this invention is to provide a method for monitoring and correcting the decompression process during diving.

[0023] Therefore, the above-mentioned objective of the present invention is achieved through the following technical solution:

[0024] A method for monitoring and correcting the decompression process of a diver, the method being based on the aforementioned device for monitoring and correcting the decompression process of a diver, and comprising the following steps:

[0025] S1. Decompression Table Data Entry: Based on the standard air diving decompression table, the data in the decompression table is entered into the processor. The processor can store the data in tabular format and can search by identifying two conditions: diving depth and underwater working time. The selected row is used as the basis for formulating a decompression plan.

[0026] S2. Diving Status Setting: Sets the criteria for determining the diving status on the display, based on the water depth h in one second. t Follow the water depth of the previous second h t-1 Comparing, △h=h t -h t-1 If Δh > 5cm, the diving status is displayed as descending; if Δh < -5cm, the diving status is displayed as ascending; if -5cm ≤ Δh ≤ 5cm, the diving status is displayed as stationary.

[0027] S3. Voice broadcast time setting: Set the interval time △t for the voice broadcaster to broadcast the water depth. The voice broadcaster will broadcast the real-time water depth h monitored by the processor.

[0028] S4. Start diving. The diver enters the water. The surface operator clicks the start diving button on the processor. The real-time water depth monitoring graph on the monitor displays the real-time water depth of the diver and automatically plots the water depth change curve. The diving status on the monitor displays the diving status.

[0029] S5. Decompression begins. The diver has completed their underwater work. The surface operator clicks the start decompression button on the processor. The processor records the maximum depth H of the diver, and the timer records the time T from the start of the dive to the completion of the dive, which is displayed on the monitor. The voice announcer announces the maximum depth H to the diver and prompts them to begin decompression and ascend one station.

[0030] S6. Formulate a decompression plan. Based on the diver's maximum water depth H and underwater working time T, the processor identifies and retrieves the decompression table to formulate a decompression plan. The processor's strategy for retrieving the decompression table is as follows: (1) Since the decompression gradient diving depth column L1 in the diving decompression table is a multiple of 3, H is entered in the processor, K = H / 3 is calculated, the smallest integer K′ greater than K is returned, and P = 3 * K′ is calculated; (2) Since the time interval of the underwater working time column L2 at each diving depth in the decompression table is not very regular, the underwater working time at each diving depth is divided into intervals according to the time interval. If the underwater working time T falls within a certain interval, the maximum value T′ of this interval is returned; (3) Formulate a decompression plan according to the row where the diving depth P and underwater working time T′ are located in the decompression table. The target ascent rate curve and the dwell time at each station in the decompression plan are continuously drawn on the real-time water depth monitoring graph on the display by solid lines.

[0031] S7. Voice prompts for decompression: Follow the voice prompts to decompress and ascend one station. The diving status on the display will show ascent. When the diver reaches the target depth, the voice prompt will emit a "beep beep beep" sound for 5 seconds to remind the diver, and the diving status on the display will show as stationary.

[0032] S8. Real-time recording of the diver's decompression process: The diver's ascent depth is recorded in real time using a depth sensor, and the actual ascent curve is continuously drawn as a dashed line on the real-time depth monitoring graph on the display.

[0033] S9. Adjust decompression time for each station. Based on the ascent speed of different divers, the processor adjusts the decompression time. Total decompression time for each station = ascent time for each station + dwell time for each station. If the diver's ascent speed is greater than the target ascent speed, the ascent time is shortened. The time saved by shortening the ascent is added to the dwell time to ensure the minimum requirement for total decompression time for each station. If the diver's ascent speed is less than the target ascent speed, the ascent time for this station is increased. The dwell time for this station is calculated from the time after reaching this station to ensure the minimum requirement for dwell time for each station. The target curve for the total decompression time for each station in subsequent stations is shifted accordingly.

[0034] S10. After the current station stay time meets the decompression time requirement, proceed to the next station according to the decompression prompt from the voice broadcast, and repeat steps S7-S9.

[0035] S11. After the diver ascends to the final decompression station, they surface. The surface operator clicks the decompression end button on the processor, and the real-time water depth monitoring graph on the display automatically generates and displays the diving process and the corrected decompression process. The data recorded by the processor can be saved and exported.

[0036] This invention provides a device and method for monitoring and correcting decompression during diving, which, compared with the prior art, has the following advantages:

[0037] Beneficial effects:

[0038] (1) This invention uses a voice broadcaster to broadcast the diver’s water depth and position in real time and give instructions, so that the diver can know his position and next operation in a timely manner, which solves the problem of not being able to see the diving watch in a blurry underwater environment. In addition, the continuous voice broadcast helps to refresh the diver and increase the diver’s sense of security.

[0039] (2) The present invention can automatically monitor the diver’s diving depth changes and record the maximum depth. The processor can automatically formulate a target decompression plan based on the water depth and underwater working time, and guide and prompt the diver to perform ascent decompression, thus solving the problem of heavy reliance on diving supervision.

[0040] (3) The present invention can monitor the ascent speed and dwell time of divers during decompression in real time, accurately determine whether the total dwell time requirement for each decompression station is met, and adjust the decompression plan in real time according to the decompression ascent speed habits of different divers during the decompression process, so as to avoid decompression sickness caused by insufficient decompression time and effectively ensure the safety of divers.

[0041] (4) The present invention can observe the diver's diving process and water depth in real time on the display and draw curves, improve the visualization effect, and help to judge the diver's diving and decompression status. Attached Figure Description

[0043] Figure 2 The flowchart illustrates the diver's decompression monitoring and correction method provided by this invention.

[0044] Figure 3 This is a real-time water depth monitoring diagram with corrections for the diving decompression process monitoring in Example 1.

[0045] Figure 4 This is a real-time water depth monitoring diagram with corrections for the diving decompression process monitoring in Example 2. Detailed Implementation

[0046] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1As shown, the diver's decompression monitoring and correction device includes a diving helmet 110, a depth sensor 111, a voice announcer 112, and a processing display 130. A light 113 and a camera 114 are installed on the top of the diving helmet 110. The depth sensor 111 is fixed to the top of the diving helmet 110 with screws. The voice announcer 112 is installed on both sides of the diving helmet 110 with screws. The depth sensor 111 and the voice announcer 112 are connected to the processing display 130 through a first signal cable 121 and a second signal cable 122, respectively. The processing display 130 is integrated by a processor 131, a timer 132, and a display 133 through a power signal cable 134.

[0048] The first signal cable can transmit the data from the depth sensor to the processor in real time.

[0049] The second signal cable can transmit the water depth data monitored by the processor to the voice broadcaster via acoustic signals.

[0050] The processor has buttons for starting diving, starting decompression, and ending decompression.

[0051] When the processor triggers the start diving button, the timer starts counting down; when the decompression end button is triggered, the timer stops counting down.

[0052] The data processed by the processor and the timer's output can be displayed on the screen.

[0053] The display screen shows the maximum diving depth, underwater working time, diving status, and real-time water depth monitoring graph.

[0054] like Figures 2-4 As shown, the method for monitoring and correcting decompression during diving includes the following steps:

[0055] 1) Decompression table data entry: Based on the standard air diving decompression table, the data in the decompression table is entered into the processor. The processor can store the data in tabular format and can search by identifying two conditions: diving depth and underwater working time. The selected row is used as the basis for formulating a decompression plan.

[0056] 2) Diving Status Settings: Set the criteria for determining the diving status on the display, based on the water depth h calculated in one second. t Follow the water depth of the previous second h t-1 Comparing, △h=h t -h t-1 If Δh > 5cm, the diving status is displayed as descending; if Δh < -5cm, the diving status is displayed as ascending; if -5cm ≤ Δh ≤ 5cm, the diving status is displayed as stationary.

[0057] 3) Voice broadcast time setting: Set the interval time △t = 30s for the voice broadcaster to broadcast the water depth. The voice broadcaster will broadcast the real-time water depth h monitored by the processor.

[0058] 4) Start diving. The diver enters the water, and the surface operator clicks the start diving button on the processor. The real-time water depth monitoring graph on the monitor displays the real-time water depth of the diver and automatically plots the water depth change curve. The diving status on the monitor displays the diving status.

[0059] 5) Start decompression. Once the diver has completed their underwater work, the surface operator clicks the start decompression button on the processor. The processor records the maximum depth H of the diver, and the timer records the time T from the start of the dive to the completion of the dive, which is displayed on the monitor. The voice announcer announces the maximum depth H to the diver and prompts them to begin the ascent to the next station.

[0060] 6) Formulate a decompression plan. Based on the diver's maximum water depth H and underwater working time T, the processor identifies and retrieves the decompression table to formulate a decompression plan. The principle of the processor retrieving the decompression table is as follows: (1) Since the decompression gradient diving depth column L1 in the diving decompression table is a multiple of 3, H is set in the processor, K = H / 3 is calculated, the smallest integer K′ greater than K is returned, and P = 3 * K′ is calculated; (2) Since the time period of the underwater working time column L2 at each diving depth in the decompression table is not regular, the underwater working time at each diving depth is divided into intervals according to the time period. If the underwater working time T falls within a certain interval, the maximum integer T′ of this interval is returned; (3) Formulate a decompression plan according to the row where the diving depth P and underwater working time T′ are located in the decompression table.

[0061] Example 1

[0062] The diver's maximum water depth H = 21m, and the underwater working time T = 36min. Then K = H / 3 = 21 / 3 = 7. Return the smallest integer greater than 7, K′ = 8, P = 3 * K′ = 3 * 8 = 24m. Since T = 36min falls in the interval [35, 45), then T′ = 45min. Therefore, the decompression plan is formulated according to the row of the decompression table where the water depth gradient is 24m and the underwater working time is 45min.

[0063] Example 2

[0064] The diver's maximum water depth H = 22m, and the underwater working time T = 35min. Then K = 22 / 3 = 7.33. Return the smallest integer greater than K, K′ = 8. P = 3 * K′ = 3 * 8 = 24m. Since T = 35min falls in [35, 45), then T′ = 45min. Therefore, formulate a decompression plan according to the row of the decompression table where the water depth gradient is 24m and the underwater working time is 45min.

[0065] The target ascent rate curve and the dwell time at each station in the decompression scheme are plotted continuously as solid lines on the real-time water depth monitoring graph on the display.

[0066] 7) Voice prompts for decompression: Follow the voice prompts to decompress and ascend one station. The diving status on the display will show ascent. When the diver reaches the target depth, the voice prompt will emit a "beep beep beep" sound for 5 seconds to remind the diver, and the diving status on the display will show as stationary.

[0067] 8) Record the diver's decompression process in real time. The diver's ascent depth is recorded in real time by a depth sensor. The actual ascent curve is continuously drawn as a dashed line on the real-time depth monitoring graph on the display.

[0068] 9) Adjust decompression time for each station: Based on the ascent rate of different divers, the decompression time is adjusted by the processor. The total decompression time for each station = ascent time + dwell time. For a diving depth of 24m and an underwater working time of 45 minutes, the decompression plan requires the diver to ascend from 24m to the first stop at 6m depth in 3 minutes. The diver then spends 6 minutes at the first stop at 6m depth, for a total decompression time of 3 + 6 = 9 minutes. The diver then ascends to the 3m stop at 3m depth in 1 minute, spends 20 minutes at the stop at 3m depth, and then ascends to the surface in 1 minute. The total decompression time = 3 + 6 + 1 + 20 + 1 = 31 minutes, which matches the time in the decompression schedule.

[0069] In Example 1, the diver's actual ascent time from a depth of 21m to a depth of 6m at the first decompression stop is 1 minute. Arriving at the first decompression stop 2 minutes early, this 2 minutes is added to the decompression time at the first stop, making the total decompression time at the first stop 2 + 6 = 8 minutes. This ensures the minimum requirement of a total decompression time of 1 + 8 = 9 minutes at the current decompression stop. The diver then ascends to a depth of 3m, with an ascent time of 1 minute. After a 20-minute stay at the 3m decompression stop, the diver emerges from the water with an ascent time of 1 minute. The total decompression time = 1 + 8 + 1 + 20 + 1 = 31 minutes, which is not less than the total decompression time in the decompression table.

[0070] In Example 2, the diver's actual ascent time from a depth of 22m to a depth of 6m at the first decompression stop is 5 minutes. Arriving at the first decompression stop 2 minutes late, the time after this 2-minute delay is counted as the decompression time at that stop. Therefore, the diver remains at the first decompression stop at 6m for 6 minutes, making the total decompression time at the first decompression stop 3 + 2 + 6 = 11 minutes, ensuring the minimum required decompression time of 6 minutes at the current stop. The diver then ascends to a decompression stop at 3m for 1 minute, spends 20 minutes at the 3m stop, and then ascends again for 1 minute. The total decompression time is 3 + 2 + 6 + 1 + 20 + 1 = 33 minutes, which is not less than the total decompression time in the decompression table.

[0071] The target decompression scheme curve is represented by a solid line in the real-time water depth monitoring graph on the display, while the actual decompression process curve is represented by a dashed line in the real-time water depth monitoring graph on the display.

[0072] 10) After the current station stay time meets the decompression time requirement, move up to the next station according to the decompression prompt from the voice broadcast, and repeat steps S7-S9.

[0073] 11) After the diver ascends to the final decompression station, the diver surfaces, and the surface operator clicks the decompression end button on the processor. The real-time water depth monitoring graph on the monitor is automatically generated and displayed, showing the diving process and the corrected decompression process. The data recorded by the processor can be saved and exported.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
