Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same functions and contents will be described using the same reference numerals.

FIG. 1 shows an embodiment of the overall configuration of a rescuer system for a swimmer in a swimming pool according to the present invention. In FIG. 1, 1 is a network server, 1A is a communication line, 10 is a group of receiving and transmitting devices (same as a wristwatch), 30 is a buoy group, 20 is a GPS satellite, 2 is a CPU (central processing unit), 3 is a ROM, 4 is a main memory, 5 is a storage device, 7 is a display device, 8 is an input device, and 9 is a terminal device group. The swimmer inputs in a format that sequentially answers the questions in the question format displayed on the display screen (monitor) of the terminal device group 9 installed at the entrance of the swimming pool. The input method can correspond to Korean, English, Chinese, etc. using a key word, a mouse, a display screen touch panel, or the like, so that the language can be selected and input in the language specified by the user. Connection to the server 1 is established by a communication network line (not shown) such as an intranet, the Internet, or an extranet, and can be connected to a mobile phone, a PHS (Personal Handyphone System), or a PDA (mobile terminal, mobile computer). ing. By entering and accessing from a mobile phone or PDA, it is possible to know the congestion situation at the time of entrance, and to avoid part of the procedure on site. The personal data of each swimmer input from the terminal device group 9 (personal computer including a desktop PC or notebook PC) connected to the server 1 via the network at the time of admission includes an identification code (ID) as personal data. 1 is recorded and saved in one recording device 5. In addition, each swimmer measures oxygen saturation, heart rate, height, and weight when entering, and these are also recorded and stored in the storage device 5 as personal data. After completing the input of personal data, each swimmer is provided with a receiving / transmitting device 10 and wear 11 from the swimming pool. And guidance is received about the operation method of the transmission / reception apparatus 10, the wearing method of the wear | wear 11, and those usage methods. The explanation can also be received by a video monitor installed around the entrance or the display device of the terminal device 9. These explanations include precautions such as how to use the swimming pool and manners when swimming.

Next, the server 1 can be connected to a receiving / transmitting device 10 supplied to each swimmer via a communication line 1A with a mobile phone, a PHS, etc., and a GPS satellite (global positioning system) disposed at a predetermined location of the swimming pool. It is also possible to connect to a plurality of buoy groups 30 whose positions are confirmed by radio wave reception with 20. That is, the transmitting / receiving device 10 and the buoy group 30 each have a built-in modulation and demodulation modem (not shown), and transmit / receive data to / from the server 1 according to the present invention via a normal telephone line using a mobile phone or PHS. . The receiving / transmitting device 10 and the buoy incorporate a power supply unit (not shown) for operating them.

Each swimmer carries a diver-type wristwatch 10 that has been waterproofed, and the display unit 10a of the wristwatch 10 displays the normal time, oxygen saturation, heart rate, and depth. The display can be switched from the display switch 10a to the mode switch 10e, but the display mode can be switched automatically at a predetermined time interval. The oxygen saturation is sequentially updated and displayed on the display unit 10a together with the measured values of heart rate and depth. For example, when the value of oxygen saturation of 100% is changed to 96% as a result of the next measurement, the changed value is sequentially updated and displayed on the display unit. On the other hand, in the case of the depth measurement value, when 0.3 meter is changed to 1.5 meters, the depth value is updated and displayed on the display unit 10a.
In this case, when the oxygen saturation and the other modes are changed at the same time, the mode changed at the same time in a blinking manner is displayed, and the swimmer can view the swimming situation as appropriate. These measurement results are sequentially transmitted to the server 1 as data, and the server 1 sequentially records and saves the data in the storage device 5.

Data transmitted from the receiving / transmitting device 10 carried by the swimmer and a signal from the receiving / transmitting device 10 to the buoy 30 are transmitted to the server 1 from the buoy 30 via the communication line 1A. The server 1 identifies the receiving / transmitting device 10 registered in the server 1 in advance as to whether the received data is a signal from the receiving / transmitting device 10 carried by the swimmer or the data transmitted from the buoy 30. The code and the identification code of the buoy 30 registered in the same manner are used. The exchange of signals between the receiving / transmitting device 10 and the buoy 30 is performed underwater because it is underwater. Signals between the buoy 30 and the server 1 can also be transmitted via a telephone line such as a mobile phone or PHS.

Hereinafter, examples of each configuration of the embodiment of the present invention will be described.
FIG. 2 is an embodiment diagram showing a configuration of the transmission / reception device 10 carried by each swimmer. In FIG. 2, 10a is a display unit, 10b is an oxygen saturation sensor, 10c is a heart rate sensor, 10d is a depth sensor, 10e is an ultrasonic transmission device, 10f is a GPS device, 10g is a timekeeping device, and 10h is a switch. Each measurement data in the transmitter 10 is sequentially transmitted to the server 1 via the communication line 1A.

In the case where the transmitter / receiver main body 10 is an embodiment of the shape of an external wristwatch, the oxygen saturation sensor 10b is measured in close contact with the artery inside the wrist. If the heart rate can be measured simultaneously when measuring oxygen saturation, the heart rate sensor 10c need not be provided separately, but can be provided separately from the oxygen saturation sensor 10b.

Signals are transmitted to the ultrasonic transmission device 10e from two routes: a signal transmitted directly from the server 1 and a signal transmitted from the server 1 via the buoy 30. The ultrasonic transmission device 10e is driven by a signal based on an abnormality determination in which an abnormal signal arrives first among two routes. It is also driven by a swimmer's switch operation. Ultrasound is transmitted by these driving. The abnormal signal of the server 1 can be transmitted by changing the frequency of the signal. The data when the swimmer dives in the water is transmitted to the buoy 30 by ultrasonic waves transmitted from the ultrasonic transmitter 10 e and transmitted to the server 1 through the buoy 30.

The time counting device 10g has a normal clock function, and the time is also read by ultrasonic waves transmitted from the ultrasonic transmitter 10e. Time data, oxygen saturation data, and heart rate data are sequentially transmitted to the server 1.

The switch 10h drives the ultrasonic transmission device 10e. In order to prevent erroneous operation, the ultrasonic transmitter is set to be driven only when the switch is kept pressed for a certain time, for example, 2 seconds or more.

FIG. 3A is a block diagram illustrating an embodiment of the configuration of the buoy 30 disposed at a predetermined position in the swimming pool. Each buoy 30 acquires an identification code, performs position confirmation by receiving GPS radio waves from a GPS satellite, and confirms the position together with the identification code of each buoy 30 with a server via a communication line. Moreover, the buoy 30 receives the ultrasonic wave which the ultrasonic transmitter 10e of the receiving / transmitting apparatus 10 which a swimmer carries is transmitted. The identification code of the transmission / reception device 10 carried by the swimmer and the values measured by the oxygen saturation sensor 10b, the heart rate sensor 10c, and the depth sensor 10d built in the transmission / reception device are read by ultrasonic waves. These signals are transmitted to the server 1 together with the identification code of the buoy 30. FIG. 3B is a diagram illustrating a state where an area where the ultrasonic waves of the buoy 30 reach and an area where the ultrasonic waves of the other buoy 30 reach overlap (overlap). There is a limit to the area (zone) where the ultrasonic waves received and transmitted by each swimmer's receiving and transmitting device 10 and the ultrasonic waves received and transmitted by each buoy 30 reach. Therefore, when the area where the ultrasonic waves of one buoy 30 reaches and the area where the ultrasonic waves of other buoys 30 are overlapped (overlap), the server 1 has the swimmer corresponding to those overlapping areas. A signal is transmitted from each overlapping buoy 30. On the other hand, when a swimmer is not submerged in the server 1, a signal is also transmitted from the transmitting / receiving device 10. In such a case, the server 1 sequentially receives them as data, and saves and records them in the storage device 5 as data.

FIG. 4 is a block diagram showing an embodiment of the configuration of the wear 11 lent together with the receiving / transmitting device 10 from the swimming pool. The wear 11 registers its identification code in the server 1 and is recorded and stored in the server 1 corresponding to the identification code of the transmitting / receiving device 10. The wear 11 includes an ultrasonic receiver 11a, an air cylinder plug 11b, and an air cylinder 11c.
The wear 11 expands when the air in the air cylinder is filled into the wear 11. The air is filled into the wear 11 by the swimmer pulling the air cylinder plug 11b with the string 11d, or by automatically receiving the ultrasonic wave transmitted from the transmission / reception device. Can be opened manually. When the inside of the wear 11 is filled with air and inflated, the wear 11 becomes a floating bag, and the swimmer can quickly rise to the surface of the water. In addition, the swimmer's wear 11 is filled with an amount of air that can reliably rise to the water surface by calculating the expansion volume based on the height and weight. For safety reasons, buoyancy is 7.5 kg or more (for children under 40 kg body weight, buoyancy is 5 kg or more, for children under 15 kg body weight, buoyancy is 4.0 kg or more). Fill the air volume with reference to "Article 53". The buoyancy of the present invention is generally from 8.0 kilograms to 10 kilograms. In addition, a beginner of swimming can transmit an ultrasonic wave by operating a switch to open the plug 11b of the air cylinder, or pull the string 11d of the wear 11 to open the plug 11b of the air cylinder.

FIG. 5 is an example of a determination table recorded and stored in advance in the storage device 5 of the server 1. The table is composed of codes, judgment items, and abnormal values, and the codes and abnormal values are defined to constitute a data group. The normal value of oxygen saturation is set to 96% or more. When it was less than 95%, respiratory failure was suspected, and when it was less than 90%, oxygen was inhaled.
Code Judgment item Abnormal value 001 Oxygen saturation 95% or less 002 Heart rate 85 or more 003 Depth over 10M 004 Scheduled end time Over 60 minutes If any one of the judgment items exceeds or exceeds the abnormal value, It is supposed to be abnormal. These values are not based on those who have developed cardiopulmonary function, such as special trainees, but for the sake of safety, normal people were used as reference values. In the case of training for swimming athletes, the level of abnormal values can be set high because swimmers who have developed cardiopulmonary function are targeted. The definition and contents of the table can be changed, for example, set to a low value corresponding to the target person or natural conditions. For example, depending on natural conditions such as water temperature, water flow, and wind speed, it is possible to set the value of oxygen saturation to 95% or less to 95% or less. In accordance with this, the abnormal values of other judgment items can be changed.

FIG. 6 is text data showing an embodiment in which each swimmer's receiving / transmitting device 10 is directly and sequentially transmitted to the server 1. In the server 1, the data transmitted from each swimmer's receiving / transmitting device 10 is converted into text data, the text data is further converted into spreadsheet data, and the converted data and the abnormal values are converted into spreadsheet data. The comparison table value is compared and the data determined to be abnormal is displayed on the display device 7 of the server 1 together with the display device 7 of the server 1 in a characteristic display different from other data. As a characteristic display example, the entire or part of the corresponding data line is colored in red, or the corresponding data line is displayed in a blinking manner, so that the monitor can immediately observe the occurrence of the abnormal value. Furthermore, it is also possible to blink a special sound or a display device in the terminal device 9 as a signal of occurrence of an abnormal situation.
1 M0100005 001 0980 002 075 003 090-0140 004 01 005 200408825112510

In this embodiment, “1” in the data is the serial row number, M0100005 is the identification code, “001” is the oxygen saturation code, “0980” is the oxygen saturation value, and “002” is the heart rate. Code “075” is heart rate, “003” is blood pressure code, “090-140” value, “004” is depth code, “01” is depth (unit meter) value, “005” is year and month The code of “day, hour, minute, second” “20040825112510” indicates time, and indicates August 25, 2004, 11:25:10.

In the embodiment of the abnormal value determination table shown in FIG. 5, the server 1 compares the code with the abnormal value, and the swimmer with the identification code “M0100005” has the oxygen saturation value of 98%. Judge that there is no situation. On the other hand, the server had a “W0300101” swimmer with an oxygen saturation value of 95% and a heart rate of 85, and the results of comparing and calculating the codes and values in the decision table were the same. Even in the case of such the same value, the server 1 determines that it is abnormal. Then, an abnormality signal is transmitted to the swimmer with the corresponding identification code “W0300101” to notify the abnormality. When there is no response from the swimmer with the identification code “W0300101”, an abnormal signal is transmitted and an ultrasonic wave is transmitted from the swimmer's receiving / transmitting device 10.

Similarly to the case of the embodiment shown in FIG. 5, the data transmitted / received to the server 1 from each buoy 30 is transmitted sequentially from the receiving / transmitting device 10 by ultrasonic waves to the server 1. Is processed as data transmitted to the server 1. That is, the transmitted data is converted into text data, and the text data is further converted into spreadsheet data. Then, the data converted into the spreadsheet data is compared with the value of the abnormal value determination table, and the data determined to be abnormal is displayed on the display device of the network-connected terminal device 9 together with the display device 6 of the server 1. Is displayed by a characteristic display such as blinking display or colored display.

Hereinafter, the configuration of the server 1 and an example of the operation flow of the embodiment of the present invention will be described. In FIG. 7, reference numeral 1 denotes a server, which is a general-purpose desktop or notebook type personal computer. Therefore, the server 1 has a configuration of a known personal computer such as a central processing unit CPU2, a ROM 3, a main memory 4, a VRAM (video ram) 5, a display device 6, an input device 7 such as a keyboard and a mouse. Further, a storage device such as a hard disk or a rewritable DVD can be added to the outside. The CPU 2 is connected to the bus, and each device device in the server 1 is controlled by the CPU 2. The ROM 3 records a system control program, and the external memory and the storage device 5 (including a computer-readable portable medium memory, semiconductor memory, hard disk, etc.) record a processing program or application program. The program according to the present invention is recorded in the recording device 5 readable by the server 1 and can be provided by transmission / reception using various communication networks via a communication line. The CPU 2 executes processing such as character output and spreadsheet processing based on a system control program recorded in the ROM 3 or processing stored in an external memory or an application program. The main memory 4 temporarily stores data for the work of the CPU 2 and functions for data processing. In this way, the CPU 2 controls the processing of the ROM 3, the main memory 4, the VRAM 5, the display device 6, and the input device 7.

The features of the embodiments and examples of the present invention are listed below.

FIG. 8 shows an example of personal data of each swimmer recorded in the storage device 5 of the server. In this embodiment, as the user information, each swimmer registers in advance a user name, oxygen saturation value, heart rate, swimming start time, swimming end scheduled time, age, identification code, and the like in the server. The swimmer inputs in a form that sequentially answers the items in the question format displayed on the display screen of the terminal device 9 installed at the entrance of the swimming pool. It can also be entered from a telephone line such as a mobile phone or PDA. The individual data of each swimmer input at the time of entry is recorded and stored in the recording device 5 of the server 1. As the data to be stored, an identification code, name, sex, age and address are input, and the oxygen saturation, heart rate, height and weight measured at the time of admission are stored as a record. As other personal data, preferential discount privilege data based on the number of uses is also recorded. As a privilege example, a 10% discount privilege is set for a user three times, and the service can be tabulated such as the advantage of a 10% reduction from the total amount and a separate prize can be acquired at the time of payment.

The wear size identifies the amount of air that fills the cylinder in S, M, and L sizes. The amount of air to be filled in the cylinder is set regardless of gender, but the wear has a variation in appearance design depending on the age of gender so that the swimmer can choose the wear according to their preference. In addition, various shapes such as a vest type, a neck type, a jumper type, and a pouch type can be prepared.

FIG. 9A is an operation flow example when the server 1 finds an abnormality in the signal of the swimmer. S1 is a swimmer identification code confirmation processing step. S2 is a step of collating the received identification code of the swimmer with the identification code of the swimmer registered in the server. Here, if the identification code does not match, the server ends the swimmer's data processing.
S3 is an abnormal value confirmation processing step of comparing and calculating data transmitted from each swimmer during swimming in the swimming pool and the value of the data group of the determination table. Here, when the result that there is no abnormality is obtained, the data processing of the swimmer is ended. On the other hand, if it is determined that there is an abnormal value, the process proceeds to the next S4.
S4 is a step of determining whether or not there is an abnormality in data in which the value of the data transmitted from the swimmer is the same as or exceeds the value of the data group in the determination table. If there is no abnormality, the process is terminated. If there is an abnormality, the next step S5 and S6 is a rescue operation command and the highlighted display is moved to the rescue operation command processing step. In step S5, as a result of comparing and calculating the oxygen saturation value, the heart rate, the depth, and the scheduled end time in step 4, it is determined that there is an abnormality when even one data is equal to or exceeds the value in the abnormal value determination table, The result is displayed by emphasizing the abnormal value data on the display device 7 of the server 1 and the display device of the terminal device 9 provided in the emergency center. This is a step of transmitting the alarm sound registered in. On the other hand, if it is determined that there is no abnormality, the process is terminated.
S6 is a step of transmitting an abnormal signal to the corresponding swimmer of the identification code determined to be abnormal in step 4. Step 6 is processed at the same time as the rescue dispatch command processing in step 5, and transmits a signal to the swimmer's receiving / transmitting device 10. At the same time, this abnormal signal is transmitted to the swimmer's receiving / transmitting device 10 via the buoy 30.
S7 is a step of confirming whether or not there is a response from the swimmer who has transmitted the abnormal signal. This step loops until there is a response from the swimmer and repeats the process. When it is determined that there is no response, an instruction to transmit an ultrasonic wave provided in the receiving / transmitting device 10 is given. On the other hand, if there is a response, the process ends.
Step S8 is a step of turning on the ultrasonic wave transmission drive switch 10g from the server 1 to the swimmer receiving / transmitting device 10. The ultrasonic receiving device 10e of the receiving / transmitting device 10 is driven to transmit ultrasonic waves when switched on. Here, it is a process when it is determined that there is no response in the abnormal signal transmission process of step 6, and is a step of instructing ultrasonic transmission provided in the receiving / transmitting apparatus 10. If there is no response to the abnormal signal in step 6, the air cylinder plug 11b is opened by ultrasonic transmission of the swimmer's receiving / transmitting device 10, but the air cylinder plug 11b is opened. Make sure you did. If there is no response to confirming the opening of the air cylinder stopper 11b, it is considered that the air cylinder stopper 11b has not been opened, and the processing is repeated until there is a response.

FIG. 9B is an operation flow example of the swimmer receiving / transmitting device 20 when the server 1 finds an abnormality in the signal of the swimmer.
S <b> 9 is an ultrasonic wave transmission processing step toward the wear 11 by the abnormal signal transmission from the server 1. The air cylinder plug 11b provided in the wear 11 is to be opened by this ultrasonic transmission. Next, S10 is a step of confirming that the air cylinder stopper 11b is opened as a result of transmitting ultrasonic waves from the transmitting / receiving device 10. When the air cylinder plug 11b is opened, the signal transmitted from the wear 11 is confirmed by the ultrasonic wave of the transmitting / receiving device 20. S11 is a step of transmitting the result confirmed in step 10 to the server 11.

FIG. 9C is an example of a normal operation flow of the transmitting / receiving device 10. In this flow, statuses such as oxygen saturation, heart rate, and time of each swimmer are sequentially transmitted to the server 1 via the transmitting / receiving device 10 and the buoy 30. Until the abnormal signal shown in the flowchart of FIG. 9B is received, the status is transmitted through normal processing.

FIG. 9D is a flow example when the wear 11 receives an ultrasonic wave from the transmission / reception device 10. S12 is a step of opening the plug 11b of the air cylinder. As a result, the air cylinder plug 11b is opened, the air is filled in the wear 11, and the wear 11 expands.
S13 is a step of confirming that the air cylinder plug 11b is opened by light emission when the air cylinder plug 11b is opened and light is emitted. The light emission line is confirmed by the ultrasonic wave of the transmission / reception device 10, and the result of the confirmation is received by the server 1. Until the result can be confirmed, the server 1 considers that the plug has not been opened, as shown in Step 8, and loops until the confirmation response is received.

FIG. 10 is an embodiment showing the structure of a wristwatch and wear carried by each swimmer. The identification code of the wear 11 worn by each swimmer is recorded and stored in the server 1 in correspondence with the identification code of the transmission / reception device 5.

Since ultrasonic waves can be transmitted and received even in water, the air cylinder plug 11b is opened by the ultrasonic wave reception 11a. Due to the opening of the air cylinder stopper 11b, the inside of the wear 11 is filled with air instantaneously, and the wear 11 is instantly inflated to become a floating bag. On the other hand, the swimmer can also open the air cylinder plug 11b by pulling it with the string 11d. On the other hand, the air cylinder plug 11b can be automatically opened when the swimmer turns on the switch 20e of the transmission / reception device 20 and the ultrasonic reception device 11a of the wear 11 receives the ultrasonic wave. It has become. The wear 11 has a structure that instantly expands to become a floating bag.

The abnormal signal from the server 1 is received, the air cylinder plug 11b of the wear 11 is opened, the air is instantaneously filled into the wear, and the swimmer can quickly rise to the water surface. Further, a suction mouthpiece (not shown) can be installed at one end of the wear 11. The wear 11 may be provided with an air tank separately from the buoyancy air tank so that air can be sucked through the mouthpiece. Thereby, it is possible to avoid the lack of oxygen until the rescuer arrives.

The amount of air in the air cylinder 11c provided in the wear 11 sets buoyancy according to height and weight. Wear filled with the amount measured by data entry at the time of admission. The height and weight values are calculated not from the report data from the swimmer but from the measurement data at the time of entry. In the personal data file, the amount of air filled in the air cylinder is also recorded and registered. It is also possible to fill the air cylinder 11c more than a certain standard. The wear 11 has a mass of about 300 to 500 grams and a buoyancy of 8.0 to 10 kilograms.

Even if the equipment for swimming is rented to a specially designated swimmer in advance and they register directly to the server 1 from the outside such as the Internet or a mobile phone (PHS), the transmission and reception are also made. The server 1 can confirm the user's identification code and the current position by the GPS signal receiving device of the device 10.

As the user information, each swimmer registers in advance the user name, oxygen saturation value, heart rate, swimming start time, swimming end scheduled time, age, identification code, etc. in the server 1. The data transmitted from the buoy group 30 and the text data are further converted into spreadsheet data. And the data converted into the spreadsheet data, the value of the abnormal value determination table, and the user name, oxygen saturation value, heart rate, swimming start time, scheduled swimming end time, age, identification code registered in the server in advance And so on.

In the present embodiment, the determination abnormality reference value of the server 1 is that the values of the determination table and the oxygen saturation value and the heart rate that each swimmer has previously registered in the server 1 are the same or not exceeding, It can be determined to be normal, that is, no abnormality. Moreover, it is also possible to determine that there is no abnormality, that is, no abnormality even when one of the values is exceeded. It is also possible to determine that the oxygen saturation value registered in advance is abnormal only when both of the values in the abnormal value determination table are exceeded. Thereby, physical strength differences such as individual cardiopulmonary ability can be reflected in the data of the rescue system according to the present invention.

Next, the operation of this embodiment will be described. Since the individual data of each swimmer entered at the time of admission is recorded and stored in the personal data recording device 5 of the server 1, the stored data includes an identification code, a name, and the like. , Sex, age, and address, which are called from the central processing unit CPU 2 shown in FIG. 7 to the main memory 4 together with the sequential data from each swimmer and the determination table, and process the data of the three parties. The calculation result is displayed on the display device 6 via a VRAM (video ram) 5 and is displayed on the display device of each terminal device 9 by the network.
