Description

The present invention relates to a support system for drying work in which the seaweed net is floated from the surface of the sea to the air and dried in the prop-type seaweed cultivation.

Generally, when cultivating seaweed, if the seaweed net is soaked in seawater for a long time after seeding, germs and diatoms in the seawater will adhere and the seaweed buds, which still have weak antibacterial activity, will die. Therefore, in order to kill the germs and diatoms and make them less susceptible to illness, it is necessary to dry the seaweed net almost twice a day.

Here, "drying" is the so-called sun-drying (drying) of seaweed nets floating from the seabed to the air using the ebb and flow of the tide. It is done by raising and lowering the height position to be attached to the middle of the pillars erected from the seabed, but the low tide time is different every day, so the drying time of the seaweed net is also different every day, so the same moderate dry state is always stable. Getting good is a daunting task.

Even if the seaweed buds are more resistant to drying than other seaweeds, they are marine organisms, so if they are too dry, they will be injured, their growth will slow down, and they will turn reddish and of quality. This is because it causes a decline.

Therefore, the seaweed farmer predicts the timing of drying out and the required fixed time based on the astronomical tide level (normal tide level) and his own experience and knowledge, and as shown in FIG. 11, the mounting height of the seaweed net to the above columns. It is customary to position the tide (OO), but if the experience is poor, abnormal tide levels (such as meandering of the Kuroshio channel) or other climate changes occur, the actual (abnormal) tide level (abnormal) tide level ( There is a great difference between the astronomical tide level (see the dotted line in the figure) and the astronomical tide level (see the dotted line in the figure). You can't get the condition.

In this regard, Patent Document 1 describes an ideal seaweed net management system on a desk. That is, this seaweed net management system is "according to the acquisition means for acquiring the peripheral information of the seawater in which the seaweed net for cultivating seaweed is immersed, the analysis means for analyzing the peripheral information, and the analysis result. The seaweed net is provided with a lifting means for pulling the seaweed net from the seawater. "

Japanese Patent No. 6560834

However, since the peripheral information acquisition device (20) provided in the seaweed net management system of Patent Document 1 is composed of various sensors and is installed in a buoy floating on the sea, the sensor lenses are regularly cleaned. Troublesome maintenance is required, and if the time and labor are saved, highly accurate detection data cannot be acquired and the reliability of the management system is reduced.

In addition, the acquired information on the surrounding area of seawater does not include changes in the tide level or the drying time, and the state of the seawater is analyzed from the acquired surrounding information to determine whether or not the time is set in advance. In addition to the acquisition module (14), the analysis module (15) and the judgment module (16) are required as the seaweed management device (10) for the judgment, and the seaweed management program (100) is also complicated. do.

Furthermore, since a drone equipped with a camera is adopted as the seaweed state acquisition device (40), it is liable to be subject to operational restrictions such as being unable to fly due to strong winds.

Above all, the seaweed net device (30), which is a means for pulling up the seaweed net (33), includes a drive unit (32) installed on a pair of columns (31), and is operated by a control motor of the drive unit (32). Since the seaweed net (33) is automatically and mechanically lifted or lowered, the mechanism required for each of the seaweed nets (33) is too complicated and large, and one farmer manages it. It is not realistic because the initial cost and operating cost of the seaweed net are extremely high due to the fact that there are multiple seaweed nets. Since it is necessary to install the drive unit (32) in seawater exposed to salt damage, it is considered that it will not spread easily.

An object of the present invention is to solve such problems, and in order to achieve the object, in claim 1, a seaweed net attached by a hanging rope is placed in the middle of a support column erected on the seabed. It is a worker's drying work support system that floats from the air to the air.

An observation device that acquires seawater information in the environment where the above seaweed net is immersed,

A web server that receives the wireless transmission of the above seawater information acquired from the observation device, and

It consists of a user communication terminal connected to the web server via the Internet.

The observation device is equipped with a float switch that switches on / off output signals based on the mounting height of the seaweed net by moving along the pillars of the seaweed net in response to changes in the tide level.

The on-signal or off-signal output when the float switch is in a dry state where the seaweed net has emerged from the sea surface due to a drop in the tide level is used as the seawater information and wirelessly transmitted from the observation device to the web server.

By accessing the web server from the user communication terminal and referring to the fixed time from the beginning to the end when the seaweed net, which is the seawater information stored in the web server, is in a dry state, the support is It is characterized by setting or adjusting the mounting height of the seaweed net.

Further, claim 2 is a drying work support system for a worker who floats a seaweed net attached by a hanging rope from the surface of the sea to the air in the middle of a pillar erected on the seabed.

An observation device that acquires seawater information in the environment where the above seaweed net is immersed,

A web server that receives the wireless transmission of the above seawater information acquired from the observation device, and

It consists of a user communication terminal connected to the web server via the Internet.

The above observation device is equipped with a water pressure sensor that measures changes in tide level over time.

The water pressure sensor measures the height difference of the tide level and the time when the seaweed net emerges from the sea surface due to the decrease in the tide level, and the measured value of the water pressure sensor is used as the seawater information for observation. While wirelessly transmitting from the device to the above web server,

Access the web server from the user communication terminal and refer to the seawater information stored in the web server, that is, the height difference of the tide level and the fixed time from the beginning to the end when the seaweed net is in a dry state. This is characterized by setting or adjusting the mounting height of the seaweed net with respect to the support column.

The third aspect of the present invention is characterized in that the observation device includes not only a float switch or a water pressure sensor for acquiring seawater information of the seaweed net, but also a network camera for acquiring the state information of the seaweed in the seaweed net.

Further, claim 4 is characterized in that the observation device is detachably attached and fixed to a position higher than the attachment position of the seaweed net on the support of the seaweed net via a fastening band, a fastening rope, or other fasteners. And.

According to the above configuration of claim 1, it is possible to prevent the occurrence of the conventional situation where the drying time of the seaweed net is exhausted as described with reference to FIG. 11 at the beginning, and for that purpose, the seawater information of the seaweed net is acquired. As an observation device, it uses a float switch that switches the on / off output signal based on the mounting height of the seaweed net by moving along the pillars of the seaweed net in response to changes in the tide level. It can be provided as an inexpensive dry-out work support system that is easy to spread, and does not require a huge cost like the seaweed net management system described in Patent Document 1 at the beginning.

In other words, as a seaweed farmer, based on the astronomical tide level and one's own experience, the timing of drying out the seaweed net and the required fixed time are predicted, and the seaweed net is attached to the predicted height position of the support. The actual tide level change may be observed by the above observation device, and then the on-signal or off-signal output when the float switch becomes a dry state where the seaweed net has emerged from the sea surface due to the decrease in tide level is output to the seawater. Information will be transmitted wirelessly from the observation device to a web server such as the Nori Nori Culture Support Center, and will be stored and stored in that web server.

Therefore, the user communication terminal of the seaweed farmer accesses the web server to browse and refer to the stored seaweed net, which is the stored seawater information, for a certain period of time from the beginning to the end of the dried seaweed net.

And, the actual observation data by the float switch of the above observation device is the result that there is an excess or deficiency in the dry state and the dry state at the predicted height of the seaweed net, for example, as that of the previous day (24 hours). In that case, on the day of the event, the above predicted height will be used as the revised height, and the height of the nori net attached to the support will be adjusted (reset) to a higher or lower position so that the necessary and sufficient drying time and dry condition can be secured. ).

As a result, it is possible to secure almost the same required drying time every day without being adversely affected by the abnormal tide level, and it is possible to always obtain a constant and appropriate dry state. The probability of matching with the height (hit rate) also increases.

On the other hand, according to the configuration of claim 2, the observation device is provided with a water pressure sensor in place of the float switch, and the water pressure sensor is in a dry state in which a seaweed net has emerged from the sea surface due to a decrease in the tide level, like the float switch. Not only can you know the time when it became, but also the height difference of the tide level is measured and the measured value is acquired as visible observation data. In adjusting (changing) the mounting height from the predicted height to the revised height, there is also the effect of making the work easier and more accurate.

In any case, it is possible to prevent the so-called deviation of the prediction decision by the aquaculture company as much as possible regarding the mounting height of the seaweed net to the support, and the same drying time can be obtained each time. Not only the raising and lowering adjustment work, but also the work of washing off dirt and diatoms adhering to the seaweed net, the work of applying acid treatment to the seaweed net, the work of checking the growth state of the seaweed, etc. are planned during the drying time. You can do it well.

Further, if the configuration of claim 3 is adopted, the growth state of the seaweed in the seaweed net is determined and confirmed by viewing the image taken by the network camera as the state information of the seaweed from the user communication terminal. It can be useful for that.

Further, if the configuration of claim 4 is adopted, since the observation device is detachably attached and fixed to the support of the seaweed net, there is an effect that maintenance, inspection and replacement thereof can be conveniently performed.

It is an explanatory graph which shows the relational situation that the drying time of a seaweed net is lost due to an abnormal tide level.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a seaweed net drying work support system according to the first embodiment, and FIG. 2 is an operation sequence diagram of the drying work support system.

As shown in FIG. 1, the above-mentioned seaweed net drying work support system uses an observation device (A) for acquiring seawater information of the environment in which the seaweed net (N) is immersed, the observation device (A), and a mobile line. It is composed of a web server (management server) (W) for wireless communication and a user communication terminal (U) connected to the web server (W) via a communication network (Internet). Support the drying work of the seaweed net (N) to be performed.

As is clear from FIGS. 3, 4 and 5, which show the schematic stretched state of the seaweed net (N), the seaweed net (N) is placed in the middle of the support column (11) erected from the seabed of the seaweed cultivation site where the water depth is shallow. It is attached by a hanging rope (12) of a certain length. Since the tip of the hanging rope (12) that is integrally projected from the peripheral portion of the seaweed net (N) is fastened to the support (11), the fastening portion is raised and lowered to the support (11). The mounting height of the seaweed net (N) will be set or adjusted.

Each of the columns (11) is made of a fiber reinforced plastic (FRP) rod having a constant thickness (for example, diameter: about 50 mm), and many of them are in an upright state in which they are scattered and distributed at required intervals.

Then, as shown in FIG. 4, the observation device (A) for acquiring the seawater information of the seaweed net (N) is the seaweed net (N) in any one of the columns (11) in which a large number of the columns (11) are distributed. ) Is installed at a position higher than the mounting position, preferably at a height that does not sink into seawater even at high tide.

As is clear from FIGS. 1 and 4, the observation device (A) moves (elevates) according to the height change of the tide level, so that the on / off output signal is output based on the mounting height of the seaweed net (N). A floating float switch (level switch) (S) that switches, a network camera (13) that captures the state of seaweed (not shown) in the seaweed net (N) and acquires the state information (image), and its float switch. The on / off output signal of (S) is used as the seawater information of the seaweed net (N), the image taken by the network camera (13) is used as the state information of the seaweed, and any of the information is wirelessly transmitted to the web server (W). It includes a communication unit (14), a control unit (electronic circuit board) (15) that controls the communication unit (14), a float switch (S), and a network camera (13).

The float switch (S) controlled by the control unit (15) of the observation device (A) acquires the seawater information of the seaweed net (N), and the network camera (13) also acquires the state information of the seaweed. In order to continuously or preferably reduce power consumption, such information is automatically and intermittently transmitted from the communication unit (14) to the web server (W) at regular intervals (for example, about 30 minutes or 1 hour). It has become

(16) is a control box incorporating the control unit (15) and a battery (not shown) for the power source thereof. Needless to say, it is waterproof and rust-proof, and a cloth band or rope is attached to the support column (11). It is attached and fixed by a fastener (17) such as.

Further, (18) is a mounting base for the network camera (13), which is also attached and fixed to the support column (11) by a fastener (19) such as a separate band or rope. Reference numeral (20) is a solar panel for charging the battery with natural (solar) energy, which is also attached and fixed to the support column (11) via a fastener (21) such as a band or a rope.

In that case, the control box (16), the network camera (13), and the solar panel (20) are all independently and independently attached to the support column (11), so that they can be maintained and inspected. Convenient for replacement.

Further, as shown in FIG. 5, the float switch (S) is composed of a reed switch (23) built in the stem (22) and a float (25) having a magnet (24) built-in. The float (25) moves (elevates) in the vertical direction according to the change in the tide level, and the reed switch (23) switches the on / off output signal by the magnet (24).

That is, when the seaweed net (N) attached in the middle of the support column (11) sinks from the sea surface due to the rise in the tide level and becomes immersed, the float switch (S) outputs an on signal. For example, the float switch (S) also outputs an off signal when the seaweed net (N) has risen from the sea surface due to a drop in the tide level. When the seaweed net (N) is in a dry state, the float switch (S) descends along the stem (22) by its own weight and is received by the lower limit stopper (26) of the stem (22).

Reference numeral (27) is a mounting bracket for suspending the float switch (S), which has an angle shape, and a fastening nut (28) has an upper end screw shaft portion (22a) of a stem (22) attached to a horizontal plate piece (27x) thereof. The vertical plate piece (27y) of the bracket (27) is also attached and fixed to the support (11) of the seaweed net (N) by a fastener (29) such as a fastener or a fastening string. Has been done. (30) is an O-ring for watertightness, (31) is a lead wire of the reed switch (23), and it is electrically connected to the control unit (15) in the control box (16). Needless to say.

The web server (management server) (W) that wirelessly communicates with the observation device (A) at the seaweed cultivation site is installed in the seaweed cultivation support center or the department in charge of the local government, and is shown in the block diagram of FIG. In addition to being equipped with a CPU, RAM, ROM, etc. as such a control unit (32), a communication unit (33) that receives the seawater information and the state information of seaweed from the observation device (A), and a communication unit (33) that stores these information. -It also has a storage unit (34) for storage.

Further, the user communication terminal (U) used by the seaweed farmer is a device that can communicate with the web server (W) via a mobile device such as a personal computer, a tablet terminal, a smartphone, or another communication network (Internet). Sufficiently, the control unit (35) such as the CPU, RAM, and ROM as shown in FIG. 1, the communication unit (36) connected to the web server (W) via the communication network (Internet), and the observation device (the above observation device). Display unit (observation data output unit) (37) such as seawater information of the seaweed net (N) acquired by the float switch (S) of A) and state information (image) of seaweed also acquired by the network camera (13). ) And.

In using the seaweed net (N) drying work support system according to the first embodiment, the seaweed farmer drys the seaweed net (N) based on the astronomical tide level and his / her own experience and knowledge. Predicting the timing and the required fixed time, the mounting height of the seaweed net (N) with respect to the support (11) is positioned as the predicted height (OO) shown by the thin solid line in FIG. 6, and the support (11) is positioned. ), The actual tide level change is observed by the above observation device (A) at the farming site. We make empirical observations to confirm the hit / miss of the prediction decision.

That is, the float switch (S) of the observation device (A) is either an on / off signal (for example, an on signal) when the seaweed net (N) is submerged from the sea surface due to a rise in the tide level. Is output, and when the seaweed net (N) rises from the sea surface due to a drop in the tide level, the other remaining signal (for example, an off signal) is output, and the float switch (S) is used for one day (S). The output signal that switches four times in 24 hours) serves as seawater information that forms the environment of the seaweed net (N), and as shown in the operation sequence diagram of FIG. 2, the communication unit (14) of the observation device (A) supports seaweed cultivation. It is wirelessly transmitted to a web server (W) such as a center, and is stored and stored in the storage unit (34) of the web server (W).

Therefore, as a seaweed farmer, the seaweed information (W) stored in the web server (W) is accessed from the user communication terminal (U) such as a personal computer or various mobile terminals owned by the seaweed farmer. The seaweed net (N), which is the signal output display of the float switch), browses and refers to a certain period of time from the beginning to the end of the dry state.

Then, the actual observation data by the float switch (S) of the observation device (A) is that of the previous day (24 hours), and the drying time at the predicted height (OO) of the seaweed net (N) is the same as that of the previous day (24 hours). If it is found that the result is still short (less) and insufficient drying, the mounting height of the seaweed net (N) is set as the revised height (HH) shown by the thick solid line in Fig. 6 on the day of the support (11). ), By attaching (changing) the seaweed net (N) to a position higher than the predicted height (OO) to some extent, the drying time of the seaweed net (N) is lengthened. Secure (many) and reset to obtain the necessary and sufficient dry condition.

In that case, since the output of the float switch (S) is a binary on / off signal, it is not a sine wave in FIG. 6 but a square wave graph shown by a chain line, and it is assumed that the height difference of the tide level is unknown. However, as a result of knowing the fixed elapsed time from the start time to the end time of the drying time, the fixed time required for drying the seaweed net (N) is adjusted to be longer (more) or shorter (less) based on this observation data. It is easy to do.

Further, regarding the mounting height of the seaweed net (N) to the support column (11), in FIG. 6, the height is set or adjusted from the low predicted height (OO) on the previous day to the high revised height (HH) on the day. The case was explained, but conversely, at the predicted height (OO), the drying time of the seaweed net (N) is long (many), and as a result of being too dry, the high predicted height (OO) is low. When setting or adjusting to the revised height (HH), the seaweed net (N) should be attached and adjusted to a lower position lower than the predicted height (OO) of the support (11) ( (If you change it)

If it is found that the dry time and dry condition can be obtained as predicted in the predicted height (OO) on the previous day, the predicted height (OO) is used as it is and the revised height (H-) is obtained. As H), the drying work and net washing work (washing off dirt and diatoms adhering to the seaweed net) on the day can be performed as it is without changing the mounting height of the seaweed net (N) to the support column (11). Just go.

Further, in the first embodiment, since the tip end portion of the hanging rope (12) integrally protruding from the peripheral portion of the seaweed net (N) is directly fastened to the support column (11), the support column (11) The mounting height of the seaweed net (N) is adjusted (replaced) from the low predicted height (OO) in FIG. 6 to the high revised height (HH), or conversely, the high predicted height. As a work of adjusting (changing) from (OO) to a lower revised height (HH), the fastening portion of the suspension rope (12) to the support column (11) is raised and lowered. You may adopt the structure which shows the modification embodiment of FIG. 7 corresponding to 5.

That is, as is clear from FIG. 7, the tip of the suspension rope (12) is not directly fastened to the support (11), but moves (elevates) along the support (11) to the floating ring (38). , So to speak, indirectly attached, the floating ring (38) is fastened to the support (11) in a suspended state by a special attachment rope (39), and the attachment rope (39) to the support (11) is attached. The mounting height of the seaweed net (N) to the column (11) can be adjusted by raising or lowering the fastening portion or adjusting the working length (suspended length of the floating ring) of the mounting rope (39). Can be adjusted.

When the configuration shown in FIG. 7 is adopted, the mounting bracket (27) for suspending the float switch (S) is attached to the floating ring (38) by a fixing bolt (40) and a fastening nut (41) thereof. , The float (25) of the float switch (S) may be kept in a state where it can move according to the change of the tide level like the floating ring (38). Since the other configurations in the modified embodiment of FIG. 7 are substantially the same as those of the first embodiment of FIG.
Only the same reference numerals as those in FIG. 5 are entered in FIG. 7, and the detailed description thereof will be omitted.

Next, FIGS. 8 to 10 show the second embodiment of the present invention corresponding to FIGS. 1, 2 and 6, and the observation is performed in the seaweed net (N) drying work support system according to the second embodiment. The device (A) includes a water pressure sensor (42) that replaces the float switch (S) of the first embodiment.

As shown in FIG. 4, the water pressure sensor (42) is electrically connected and wired to the control unit (15) in the control box (16) of the observation device (A), and sinks from the sea surface. In water, measure the change in tide level over time. As shown in FIG. 10, the water pressure sensor (42) measures the height difference of the tide level and the drying time of the seaweed net (N) rising from the sea surface due to the decrease of the tide level, and the water pressure sensor (42) measures the water pressure sensor (42). The value is the seawater information of the seaweed net (N).

Therefore, even when using the drying work support system according to the second embodiment, as a seaweed farmer, the timing and necessity of drying out the seaweed net (N) are still necessary based on the astronomical tide level and one's own experience. Predicting a certain period of time, the mounting height of the seaweed net (N) with respect to the support (11) is positioned at the predicted height (OO) shown by the thin solid line in FIG. 10, and the support is mounted in the middle of the support (11). In this state, the actual tide level change is observed by the above observation device (A) at the aquaculture site.

As shown in FIG. 10, the water pressure sensor (42) of the observation device (A) measures the height difference of the tide level and the drying time of the seaweed net (N) rising from the sea surface due to the decrease of the tide level. As shown in the operation sequence diagram of FIG. 9, the measured value of the water pressure sensor (42) (the numerical value of the tide level is an average value) is the seawater information of the seaweed net (N), as shown in the operation sequence diagram of FIG. It is wirelessly transmitted from 14) to a web server (W) such as a seaweed cultivation support center, and is stored and stored in the storage unit (34) of the web server (W).

Therefore, the seaweed farmer accesses the web server (W) from his / her own user communication terminal (U), and the seawater information (water pressure sensor) stored in the storage unit (34) of the web server (W). The height difference of the tide level, which is the measured value of), and the fixed time from the beginning to the end of the dried seaweed net (N) are browsed and referred to.

Then, the actual observation data by the water pressure sensor (42) of the observation device (A) is that of the previous day (24 hours), and the drying time at the predicted height (OO) of the seaweed net (N) is the same as that of the previous day (24 hours). If it is found that the seaweed net (N) is still short (less) and insufficiently dried, the mounting height of the seaweed net (N) is set as the revised height (HH) shown by the thick solid line in FIG. ), By attaching (changing) the seaweed net (N) to a position higher than the predicted height (OO) to some extent, the drying time of the seaweed net (N) is lengthened. Secure (many) and reset to obtain the necessary and sufficient dry condition.

In that case, the water pressure sensor (42) not only knows the fixed elapsed time from the time when the drying time of the seaweed net (N) starts to the time when it ends, like the float switch (S) of the first embodiment. Since the height difference of the tide level is also found as visible observation data such as the sinusoidal waveform and measured values illustrated in FIG. 10, it is revised from the predicted height (OO) of the seaweed net (N) based on this observation data. It is possible to clearly determine the degree of raising to the height (HH) and the drying time that can be secured depending on the degree, and it becomes easier to concretely adjust the drying time.

Since the other configurations in the second embodiment of FIGS. 8 to 10 and their usage are substantially the same as those of the first embodiment of FIGS. 1 to 6 and the modified embodiment of FIG. 7, FIGS. 8 to 8 to 10. Only the same reference numerals as those in FIGS. 1 to 7 are entered in No. 10, and the detailed explanation thereof will be omitted.

In any of the first and second embodiments, the float switch (S) or the water pressure sensor (42) of the observation device (A) causes the seaweed net (N) to rise from the sea surface and become dry. This is acquired as seawater information of the seaweed net (N) and wirelessly transmitted from the observation device (A) to the web server (W), but by the network camera (13) of the observation device (A). Even if the photographed image of the seaweed is wirelessly transmitted to the web server (W) as the state information of the seaweed in the above seaweed net (N) and the state information is viewed, it is useful for confirming the healthy growth state of the seaweed. good.

Further, as the seawater information of the seaweed net (N), not only the change in the tide level but also the water temperature detected by the water temperature sensor and the atmospheric illuminance acquired by the atmospheric illuminance sensor can be added. When the water temperature sensor rises from the sea surface in summer, the temperature detected by the water temperature sensor rises sharply, and when the water pressure sensor also rises from the sea water surface, the detected water pressure disappears. By assuming that (N) has risen from the sea surface and is in a dry state, the water temperature sensor or water pressure sensor may be adopted as an on / off switch instead of the float switch (S) of the first embodiment. It doesn't matter.
