       FIG.  15    is a plan view illustrating a module unit of the water walking stage system according to the present disclosure. 
       FIG.  16    is a control block diagram of the water walking stage system according to the present disclosure, and  FIG.  17    is a control flowchart of the water walking stage system according to the present disclosure. The figures illustrate the operation related configuration of the water walking stage system. 
     As shown in  FIGS.  1  to  17   , a water walking stage system A according to the present disclosure includes opposite side floating bodies  10  and  10 ′ configured to float on a water surface  2 , a walking stage  20  connected under the opposite side floating bodies  10  and  10 ′ to form a footrest, and rails  30  and  30 ′ arranged to connect both sides of the walking stage  20  to the opposite side floating bodies  10  and  10 ′. 
     Therefore, the water walking stage system A may be installed partially submerged in the water near the sea beach, riverside or lakeside. In addition, when an anchor is provided, the system can be installed away from the shore, and can be installed even in a calm lake. Accordingly, the walking stage  20  is supported by the floating bodies  10  and  10 ′ floating on the water surface and is thus positioned so as to be submerged under the water surface. 
     In addition, the water walking stage system A including the walking stage  20 , the floating bodies  10  and  10 ′, and the rails  30  and  30 ′ is at least several meters on each side, and therefor can be installed as a compact facility on the riverside or lakeside. In addition, when the length of the system on each side is several tens of meters, the system may be installed on one side of a large lake, a large river, or the like, or may be installed on the shore of a small beach. Furthermore, when the system comes in a large size as to have a side length ranging from 100 m to several hundred meters, it may be installed on the shore of a large beach. 
     In particular, when the system comes in a large size and is installed on a large beach or the like, the walking stage  20 , the floating bodies  10  and  10 ′ and the rails  30  and  30 ′ may be formed of a stronger material so as to better withstand the waves and support wheelchairs, electric wheelchairs, or carts as well as users. Also, a monitoring system may be configured and coastal facilities such as anchors may be installed for safety. Of course, for the safety of users, life-saving facilities and lifeguards may be deployed in various places, and a structure for providing safety related information may be installed as well. 
     Accordingly, the walking stage  20  is arranged to be submerged below the water surface at a depth of about 1 m. Any submerge depth is acceptable as long as the depth allows an adult to walk safely. In addition, when the system is designed for children, it may be installed at a shallower depth than a system for adults, and therefore the depth may be within about 50 cm. 
     The walking stage  20  may be formed in the shape of a fine net mesh or a rod-shaped assembly in which circular, oval or rectangular rods with a small gap are connected in a parallel. The walking stage  20  may allow water to freely pass through the gaps therein, and may thus be maintained in a stable shape. 
     In addition, the walking stage  20  may be formed as a plate body on the floor. When formed as a plate body in this way, the walking stage  20  submerged in water may allow users to easily walk on the upper surface thereof. Furthermore, a wheelchair, an electric wheelchair, or a cart may move on the plate-shaped walking stage  20 . In this case, the wheelchairs, electric wheelchairs, carts, or the like are preferably configured to have corrosion resistance to seawater or moisture. Therefore, each plate body of the plate-shaped walking stage  20  will have a length of about 1 to 5 m and a width of about 20 cm to several meters on both sides. While the walking stage is illustrated as having a rectangular shape, embodiments are not limited thereto. It is natural that the stage can be configured in more diverse ways due to the variety of materials while being formed to have other lengths, widths, thicknesses, and structurally stable shapes. Also, regarding the shape, the stage may be formed not only in a rectangular shape but also in various other shapes, such as an arc shape, an elliptical arc shape, a triangular shape, a polygonal shape, and a shape that can be associated with various characters according to the installation stability and material. 
     In some cases, as shown in  FIG.  15   , the opposite side floating bodies  10  and  10 ′, the walking stage  20 , and the rails  30  and  30 ′ may be integrated into one module unit M according to an assembly structure. In this case, the water walking stage system A may be configured in various shapes as described above, using the module units of various structures ((a), (b), (c), and (d)). 
     In this regard, the opposite side floating bodies  10  and  10 ′, the walking stage, and the rails may constitute one integrated module structure, and two or more module structures may be coupled to each other by a coupling structure to complete one system. 
     The coupling structure for coupling the above-mentioned two or more module structures to each other may be one or more coupling structures selected from a group consisting of a coupling structure including a electromagnet, a coupling structure including a clasp and a ring, a coupling structure including a protrusion and a groove, and a coupling structure including a snap button. The coupling structure for the module structures may be applied in a complex way to more stably maintain the coupling. 
     In some cases, the coupling structure according to the present embodiment may operate to decouple the module structures when an emergency occurs. 
     When the walking stage  20  is formed in the shape of a plate body, it may be formed as a single-layer plate body as shown in  FIGS.  7  and  8   , or may be formed in a plurality of layers as shown in  FIG.  6   . When the stage is formed in a single layer, individual plate bodies may be fixedly installed on multiple columns  31  of the rails  30  and  30 ′, and may be connected to each other by connecting means such as a rope or a wire. When the stage is formed in a plurality of layers, the plate body of an upper layer and the plate body of a lower layer may be arranged to be misaligned with each other and fixed to the individual columns  31 . The plate bodies are misaligned such that the opposite side edges are fixed to the individual columns. The walking stage  20  may be formed as plate bodies according to various other embodiments, and is not limited by the above examples. 
     In addition, the floating bodies  10  and  10 ′ of the water walking stage system A according to the present disclosure may be formed of a foamed resin material or a buoyancy member having a hollow portion to contain a gas, as shown in  FIGS.  2  to  8   . 
     Therefore, the walking stage  20  and the rails  30  are maintained at a certain depth in the water by the buoyancy of the opposite side floating bodies  10  and  10 ′ so as not to sink in the water. 
     Accordingly, when the floating bodies  10  and  10 ′ includes a hollow portion to contain gas and a case, a moisture sensor w to detect moisture may be provided inside thereof. The moisture sensor w is configured to detect moisture when the case is damaged or cracked by an external force, and moisture infiltrates into the hollow portion. To configure the moisture sensor w, a general moisture sensor may be employed. That is, infiltration of moisture may be detected based on the electrical current and optical characteristics measured by the moisture sensor w in the event of absence of moisture and in the event of presence of moisture. 
     The floating bodies  10  and  10 ′ may be arranged to surround the entire water walking stage system A according to the present disclosure as shown in the figures and stably connected to prevent the structure of the entire water walking stage system A from being deformed. 
     To this end, a safe connector  13  is provided as an inner material inside the floating bodies  10  and  10 ′. The safe connector  13  may be configured as a reinforcing bar, a metal bar, an alloy bar, or the like. Alternatively, it may be configured as a wire in the form of a twisted pair made by twisting multiple metal wires. The safe connector  13  may be configured with multiple wires. In addition, as in  FIG.  2   , the safe connector  13  may be fixed to a fixing rod  4  installed on the ground  3 . Therefore, the water walking stage system A of the present disclosure fixed to the fixing rod  4  in addition to the anchor may remain stable even in the event of waves, high tide, low tide, and the like. 
     Also, as shown in  FIGS.  2  and  4   , the cross-section of the floating body  10  and  10 ′ may be formed in a circular shape, a rectangular shape, an oval shape, or a polygonal shape of a uniform thickness over the entire length of the safe connector  13 . Also, as shown in  FIG.  3   , the floating bodies may be formed by connecting multiple individual bodies formed to surround the safe connector  13  by forming small-sized outer bodies. In particular, when the floating bodies include multiple individual bodies surrounding the safe connector  13 , they may be configured to be easily separated from and coupled to each other. Thus, the walking stage  20  and the rails  30  and  30 ′ as well as the floating bodies  10  and  10 ′ are configured to be detachable, the water walking stage system A according to the present disclosure may be installed on the water surface when it is needed, and may be disassembled and stored when it is not in use. Thereby, convenience in use may be ensured. 
     Furthermore, when the water walking stage system A is formed in a rectangular shape, a triangular shape, or a polygonal shape as a whole as shown in  FIG.  3   , the floating bodies  10  and  10 ′, the walking stage  20 , and the rails  30  and  30 ′ may be configured as individual members. In this case, the system may be assembled to install the individual members, and may be disassembled to store and move the individual members. Thereby, convenience in use may be provided. 
     In addition, as shown in  FIGS.  5 ,  7  and  8   , the floating bodies  10  and  10 ′ may include handle parts  12  and  12 ′ on one side. Accordingly, the user may easily walk in water, holding the handle parts  12  and  12 ′. Thus, the user&#39;s head, upper body, arms, and the like are positioned above the water surface  2 , and the lower body, legs, and the like are positioned in water. Accordingly, the users may be allowed to walk on the walking stage  20  positioned in water, while holding the handle parts  12  and  12 ′ on the water surface. 
     In addition, the rails  30  and  30 ′ on the opposite sides may be formed of a mesh body or a porous plate body. The mesh body or porous body may be configured to allow water to easily flow therethrough by waves, high tides, low tides, or river flows. 
     The rails  30  and  30 ′ are provided with multiple columns  31 . The walking stage  20  is supported on the opposite side floating bodies  10  and  10 ′ by the multiple columns  31 . In addition, by connecting an offshore installation such as an anchor to the floating bodies  10  and  10 ′ by the columns  31  of the rail  30  and  30 ′, the entire structure of the water walking stage system A is stably maintained by the fixing force according to the connection. 
     When the water walking stage system A becomes heavy due to the loads of the floating bodies  10  and  10 ′, the walking stage  20  and the rails  30  and  30 ′, buoyant members may be added and installed at corresponding places. The buoyant members may be formed by a foam member such as polystyrene, or may be formed as a kind of tube in which air or other gases may be contained. 
     Furthermore, in the water walking stage system A according to the present disclosure, a safety zone  15  for safety personnel may be installed at multiple places as shown in  FIG.  4   . The safety zone  15  may be fixed to the floating bodies  10  and  10 ′, and may be configured as a foam member or a tube. 
     The water walking stage system A according to the present disclosure configured as described above may be formed in various shapes as shown in  FIGS.  9  to  14   . 
     That is, as shown in  FIGS.  9  to  11   , the system may be formed in a polygonal shape such as a rectangle, a semi-elliptical shape, and a semi-circular shape. Alternatively, the system may be formed in a closed polygonal shape such as a closed rectangle, a closed elliptical shape, or a closed circular shape, as in  FIGS.  12  to  14   . In this way, the system may be performed in various shapes. 
     Accordingly, when the system is formed in a shape open to one side as shown in  FIGS.  9  to  11   , an entrance through which a user can enter and exit may be formed on the open side of the system. When the system is formed in a closed shape as shown in  FIGS.  12  to  14   , an entrance  16  may be formed on one side. 
     The water walking stage system A according to the present disclosure may be fixedly installed on the shore, riverside, or the like. In this case, the entrance is configured to be in contact with the ground  3 , and the other parts are disposed on the water surface or in water. As described above, when the user walks along the walking stage  20  while holding the handle parts  12  and  12 ′, the user&#39;s body is gradually submerged in the water. 
     In addition, once users complete boarding the water walking stage system A, the system may be safely lifted and moved and fixed at a location several meters, tens of meters, or hundreds of meters away from the shore, such that the users can enjoy underwater activities at sea. 
     To this end, a connection part (not shown) for lifting may be installed on one side of the water walking stage system A. A propulsion part  22  may be installed on the opposite sides of the system as shown in  FIG.  12    and may be operated by a main controller  40  formed on one side. 
     In addition, the water walking stage system A according to the present disclosure configured as described above may be provided with a level area  25  formed inside thereof, as shown in  FIGS.  4  and  5   . In the level area  25 , the user may be allowed to swim and play in water. 
     Also, the level area  25  is provided with a level plate  254  at the bottom thereof. Thus, even when the water walking stage system A according to the present disclosure is installed in a deep place where it is difficult for the user to safely swim, the user can swim safely in water about the level plate  254 . The level area  25  may include a first level area  251  for adults where the depth is about 1 m, and a second level area  252  for children where the depth is about 50 cm. 
     In addition, a buoyant member  253  may be further configured on one side of the level plate  254  in order to support the load of many users. The buoyant member  253  may be formed of a foam material, and may be formed in the form of a tube containing gas. Furthermore, in response to a change in the total load according to a change in the number of users, gas may be supplied to or removed from a buoyant member containing the gas at a corresponding place among the buoyant members  253  supporting the level plate  254  or the buoyant members supporting the walking stage  20  under the control of the main controller  40 , such that the depth of the walking stage  20  and the level plate  254  remains constant. To this end, an air supply pump, an air compression tank, an air supply pipe, and a sensor may be further provided. 
     In some cases, as shown in  FIGS.  6  to  8   , the rails  30  and  30 ′ may include a variable structure whose length is changed in the vertical direction to change the depth at which the walking stage  20  under the rails is submerged in water. 
     Specifically, as shown in  FIG.  6   , the rail  30 ,  30 ′ constituting one module unit may include a first connector  30   s,  a second connector  30   e,  and an additional connector  30   i.    
     The first connector  30   s  according to this embodiment is an element to connect one side of the walking stage  20  to one side of the floating body, and has a variable structure capable of changing the connection length. 
     The second connector  30   e  is an element to connect the opposite side of the walking stage  20  to the opposite side of the floating body, and has a variable structure capable of changing the connection length. 
     The additional connector  30   i  is disposed between the first connector and the second connector. The additional connector connects the walking stage  20  to the floating bodies  10  and  10 ′, and has a variable structure capable of changing the connection length. 
     By changing the connection lengths of the first connector  30   s,  the second connector  30   e,  and the additional connector  30   i  of the rails  30  and  30 ′ configured as above, one module unit and an adjacent module unit may implement a horizontally leveled walking stage, an inclined walking stage, or a walking stage having a curved surface. 
     By using this function, the structure may be appropriately changed for children, the elderly and the disabled, and various structures may be configured in a complex manner and used for leisure. 
     The above-mentioned main controller  40  may be provided for a safe state and emergency operation of the water walking stage system A according to the present disclosure. 
     As shown in  FIG.  15   , the main controller  40  may include a safety check signal processing block  42 , an emergency notification signal processing block  43 , an input/output signal processing block  44 , and a main control unit  41  to control the members of the water walking stage system A. 
     That is, a structural safety detection member  50  may be installed on any one or more of the floating bodies  10  and  10 ′, the rails  30  and  30 ′, or the walking stage  20  to detect damages to the floating bodies  10  and  10 ′, the rails  30  and  30 ′, or the walking stage  20 . The main controller  40  may be connected to the structural safety detection member  50  to determine the state of the floating bodies  10  and  10 ′, the rails  30  and  30 ′, or the walking stage  20  and perform an operation. 
     The structural safety detection member  50  may include a safety loop line  51  formed as a continuous line along the floating bodies  10  and  10 ′, the rails  30  and  30 ′, and the walking stage  20  in a shape to be continuously enclosed. 
     The safety loop line  51  may be configured as a loop sensor to enable ultrasonic transmission/reception or transmission/reception of optical signals. The transmission/reception by the loop sensor may be configured by the transmission/reception scheme for a general loop sensor. That is, when signal transmitters (not shown) on opposite sides of the safety loop line  51  each transmit a signal, and the signal is normally received by the counterparts, the line is in a normal state without damage. However, the outgoing signal is not received on the opposite side, the state is abnormal, and the main controller  40  determines the state as an abnormal state. In this case, the signal transmitters on the opposite sides receive the signal transmitted by themselves again. Then, the position of the cut part is determined by analyzing the received ultrasonic or optical signal. 
     In addition, point sensors d may be connected to the safety loop line  51  at intervals of tens of centimeters, several meters or several tens of meters. Therefore, when the outgoing signal is not received on the opposite side, the cut position is determined by detecting the point sensor d and identifying the position of the point sensor d detected on both sides. 
     Furthermore, the structural safety detection member  50  may include a moisture detection sensor w configured in the hollow portion of the floating bodies  10  and  10 ′ as shown in  FIG.  8   . The point sensor d and the safety loop line  51  may be configured to determine whether the floating bodies  10  and  10 ′, the walking stage  20  or the rails  30  and  30 ′ are damaged. In addition, the moisture sensor w determines whether there is moisture infiltrating into the floating bodies  10  and  10 ′ when the floating bodies  10  and  10 ′ is cracked or broken and the outer bodies of the floating bodies are damaged. The moisture sensor is configured to pre-determine whether the floating bodies  10  and  10 ′ are damaged while the safe connector  13 , which firmly connects the entire structures, is not damaged. 
     In some cases, the safety connector  13  may be connected to the fixing rod by a variable wire that has a variable length or is separable. 
     In addition, an emergency button s for notifying an emergency signal may be installed at multiple places such as the handle parts  12  and  12 ′, the floating bodies  10  and  10 ′, or the safety zone  15  and the level area  25 . Therefore, in the event of an emergency in which a person needs an urgent medical care, an accident occurs in water, or damage to the water walking stage system A is found while users are walking on the walking stage  20  or swimming and playing in the water in the level area  25 , users can report the emergency situation by pressing the emergency button s. 
     As such, the structural safety detection member  50  such as the safety loop line  51 , the point sensor d, the moisture detection sensor w, or the emergency button s may be configured on a single line, on may be individually configured on multiple lines. It may be separately installed on the opposite side floating bodies  10  and  10 ′, or may be installed on individual lines on the opposite sides of the walking stage  20 . In addition, each member may be configured on an individual line. 
     A signal from the structural safety detection member  50  is transmitted via the safety check signal processing block  42  of the main controller  40 . Accordingly, the main controller  40  may determine whether the emergency state is present by determining the signal transmitted from the safety check signal processing block  42 , which is connected to the structural safety detection member  50  to receive a detection signal. 
     Accordingly, in the case of a normal signal, the controller waits for the next signal. However, when damage to the floating bodies  10  and  10 ′, the walking stage  20 , or the rails  30  and  30 ′is detected, and thus it is determined that the state is emergency, an emergency signal is transmitted to the emergency lighting  52  or the speaker  53  through the emergency notification signal processing block  43 . 
     In addition, the input/output signal processing block  44  for processing the input/output signal transmits the emergency signal for an emergency state to an external organization connected by an input/output terminal  441 . The external organization may include a management office that manages coastal facilities, and a rescue team, the police station, a hospital, and a fire station that prepare for a water play-related accident in the water walking stage system A and on the shore. 
     The water walking stage system A according to the present disclosure configured as described above may be controlled according to the following steps. 
     1) First, a system operation preparation step S 01  is performed. In the step, a water walking stage system including the floating bodies  10  and  10 ′, the walking stage  20 , and the rails  30  and  30 ′ is installed in water, and the structural safety detection member  50  is installed on one side of the water walking stage system and connected to the main controller  40  to prepare the system operation. The water walking stage system A may optionally include the level area  25 , the safety zone  15 , the emergency lighting  52 , the speaker  53 , the propulsion part  22 , and an air supply device. Also, it may include a search light block  45  configured to operate the search light  54  for illuminating a night facility. 
     In the system operation preparation step S 01 , initial values for the normal state of the individual sensors connected to the floating bodies  10  and  10 ′, the walking stage  20 , the rails  30  and  30 ′, and other installed members are received as input and stored in a memory unit  401 . Based on this initial setting data, it is determined whether there is an emergency. That is, for the safety loop line  51  of the structural safety detection member  50 , whether the signals transmitted from the signal transmitters on the opposite sides are normally received by the counterparts is related to the initial setting state. Also, for the point sensor d, whether response signals are normally received from the individual sensors is related to the initial setting state. Also, for the moisture sensor w, a value measured in the absence of moisture is the initial setting data, or a measured value according to moisture is related to the initial setting data. In this regard, in the case of the sea, the measured value is based on seawater. In the case of fresh water such as a river or lake, the measured value for the water in the corresponding region is the initial setting data. 
     Furthermore, in the case of the emergency button s, an emergency signal is received by a pressing operation, and accordingly an initial set value is et by a non-pressed state. The other members are also installed and the states thereof before use are set as initial values. These initial setting data are stored in the memory unit  401 . 
     2) Thus, the water walking stage system A is operated, and a sensor signal reception step S 02  of receiving a signal transmitted from the structural safety detection member  50  via the safety check signal processing block  42  is performed. 
     3) Then, a sensor signal determination step S 03  of determining whether the signal transmitted from the structural safety detection member  50  is a normal signal by determining the signal received from the safety check signal processing block  42  is performed. Thereby, it is determined whether the water walking stage system A operates normally. 
     4) Then, when the signal determined by the sensor signal determination step S 03  is determined to be an emergency signal, an emergency signal transmission step S 04  of transmitting the emergency signal to the emergency notification signal processing block  43  to notify an emergency through the emergency lighting  52  and the speaker  53  is performed. Therefore, users can safely prepare for the emergency through the emergency lighting  52  and the speaker  53 , and rescue workers may appropriately cope with the emergency. 
     Furthermore, in this emergency state, an emergency signal is transmitted to an external organization such as a police station, a fire station, and a hospital, and a facility management office that are connected to the input/output terminal  441  under control of the main controller  40  to appropriately cope with the emergency.
