Description

  The present invention relates to a wearable device worn by a user.

  As one of wearable devices worn by users, there has been proposed a vital sensor device that can report the occurrence of an abnormality even if the subject (user) loses consciousness (see, for example, Patent Document 1). In this patent document 1, “the vital sensor device 1 takes in a signal from the vital sensor 3 and determines whether or not there is a physical abnormality. If the occurrence of a physical abnormality is detected, the buzzer 4 generates an alarm sound. Next, if the stop button 5 is not pressed within a predetermined time after instructing the generation of the alarm sound, the current position information is acquired from the GPS module 7. The current position information and the user ID are included. An emergency signal is generated and an emergency signal is transmitted to the center, where an emergency notification device analyzes the emergency signal to obtain a user ID and current position information, and uses the user ID to convert the personal information database 14 to the user ID. The corresponding personal information is searched and read out, and the personal information and the current position information are displayed on the display device 16. "

Japanese Patent Laid-Open No. 2002-269662

The conventional technology is based on the premise that the vital sensor device and the center can communicate with each other. However, in the case of a mountain disaster or a natural disaster, the vital sensor device and the center are not necessarily communicable.
As the vital sensor device becomes smaller and lighter, it becomes more difficult to communicate in a steep mountain or the like, and there is a problem of battery life. In the case of a natural disaster, the base station itself may be damaged and communication may be interrupted. Further, considering cost reduction, battery life, and reduction in size and weight, it can be assumed that the vital sensor device does not have the communication function itself.

A terminal may be used. In addition, these mobile or fixed communication terminals may be base stations that form part of a wireless communication network. For example, mobile base stations are formed as airships or drones, used in disaster areas during disasters, etc., used to restore mobile communication networks, and can be used to construct short-range communication areas such as wireless LANs as appropriate It is. The fixed base station is installed on each floor of a building, for example, and a short-range communication area such as a wireless LAN can be appropriately constructed.

The control unit 11 uses the sensor unit 12 to detect the movement of the user 7 (acceleration, angular velocity, traveling direction (azimuth), altitude change (pressure change), etc.) and vital information itself (heart rate, blood pressure, brain wave, etc.). Thus, the activity amount and physical abnormality of the user 7 are detected. Note that a physical abnormality is determined as a physical abnormality when, for example, at least one of heart rate, blood pressure, and electroencephalogram satisfies a predetermined abnormality condition. The temperature sensor may be used to detect the body temperature of the user 7 or may be used to detect the ambient temperature. Known methods can be widely applied to detect this amount of activity and physical abnormality.

The communication unit 22 performs communication according to a standard such as a predetermined wireless communication network under the control of the control unit 21. As a result, the gateway device 3 uses various services (telephones, emergency early warning of disaster occurrence from mobile phone companies, etc.) using the wireless communication network, and various services from the communication network 4 via the wireless communication network. Can be used.
In addition, the communication unit 22 relays communication between the wearable device 2 and the communication network 4 under the control of the control unit 21. Thus, the wearable device 2 can access the communication network 4 and receive various data from various servers connected to the communication network 4.

The input unit 23 is a device for inputting an instruction of the user 7 and inputs the instruction of the user 7 via an operation switch (not shown) and a touch panel provided on the display unit 26.

In the present embodiment, a case where GPS is used is exemplified, but a position acquisition method other than GPS may be used.

FIG. 3 is a diagram illustrating the operation of the monitoring system 1.
The wearable device 2 periodically acquires the vital information of the user 7 by the sensor unit 12 under the control of the control unit 11, and determines whether there is a physical abnormality based on the vital information (step S1B). When it is determined that there is no physical abnormality (step S1B; NO), the wearable device 2 transmits vital information to the gateway device 3 through the short-range communication unit 15 under the control of the control unit 11 (step S2B). The gateway device 3 transmits vital information to the health management server 5 through the short-range communication unit 15 under the control of the control unit 21 (step S3B).
When receiving the vital information, the health management server 5 accumulates and manages the vital information for each user (step S4B).

If it is determined in step S1B that the body is abnormal (step S1B; YES), the wearable device 2 can communicate with the gateway device 3 by the short-range communication unit 15 under the control of the control unit 11. Is determined (step S5B). When communication is possible (step S5B; YES), under the control of the control unit 11, the short-range communication unit 15 notifies the wearable device 2 of the physical abnormality of the user 7, and the current position of the wearable device 2 is determined. The indicated position information and vital information are transmitted (step S6B).
The position information transmitted in step S6B is information obtained by converting the position information made up of the latitude and longitude acquired by the position acquisition unit 18 into UTM grid coordinates.
The conversion to the UTM grid coordinates is performed by the control unit 11 based on the coordinate conversion DB 14A (see FIG. 2). That is, the control unit 11 functions as a physical information determination unit that determines whether or not the user 7 is physically abnormal, and also functions as a positional information use unit that obtains UTM grid coordinates using positional information including latitude and longitude. .

Subsequently, under the control of the control unit 21, the gateway device 3 transmits an emergency call for notifying the physical abnormality of the user 7 through the communication unit 22 to the window server 6 (step S7B). When sending this emergency call, the UTM grid coordinates and vital information sent from the wearable device 2 are also sent to the window server 6.
Upon receiving this emergency call, the window server 6 responds to the physically abnormal person (user 7) (corresponding to emergency lifesaving) (step S8B). As a result, emergency life support can be automatically performed, and quick response becomes possible.
Moreover, the gateway apparatus 3 transmits the vital information at the time of a physical abnormality with the communication part 22 with respect to the health management server 5 under control of the control part 21 (step S9B). Thereby, on the health management server 5 side, vital information when the user 7 is physically abnormal is also accumulated and managed.

The UTM grid coordinates described above will be described.
The UTM grid is a grid map coordinate system defined by international standards, and is internationally called MGRS (Military Grid Reference System), a method for specifying a position on the earth, and position information expressed by this method. It is a form. The use of the UTM grid has an advantage that the position can be specified with a simple expression as compared with coordinates expressed by latitude and longitude, as will be described later.
FIG. 4 is a diagram showing an example of a UTM grid map. FIG. 5 is a diagram for explaining UTM grid coordinates, FIG. 5 (A) shows the relationship between UTN grid coordinates and latitude / longitude, and FIG. 5 (B) shows the structure of UTN grid coordinates. FIG.
The UTM grid map is a map obtained by dividing a map created by the universal horizontal Mercator projection in the north-south direction and the east-west direction in units of a predetermined length. The UTM grid map has grids (ruled lines) extending in the north-south direction and the east-west direction at predetermined intervals, and specifies an area (range) divided by the grid by coordinates. These coordinates are called UTM grid coordinates.
A typical UTM grid has the largest division of the target area (which may be the whole earth) divided by 100 km square, and this divided 100 km square is separated by any one of 100 m, 10 m, and 1 m. Separate by grid. The UTM grid coordinates have a hierarchical structure in which a 5-digit area code assigned to the largest section and a code having a predetermined number of digits that specify the position in this section are combined.

  The 5-digit area code that identifies the 100 km square is, for example, “53SME” illustrated in FIG. “53” included in this area code is a coordinate body number indicating a position in the east-west direction. The area code “S” is obtained by dividing the latitude direction (north-south direction) every 8 degrees and assigning one alphabetic character. The area code “ME” is a code indicating a UTM 100 km square area code specifying 100 km square. The coordinate body number in the east-west direction corresponds to the range of longitude (132-138 ° east longitude in the example in the figure), and the code indicating the position in the north-south direction is the latitude direction every predetermined length (8 ° in the example in the figure). Corresponds to the range when separated. The area code can be omitted. For example, when a position is expressed in UTM grid coordinates for the entire country of Japan, an area code is required because the target range is significantly larger than the maximum division of 100 km square. On the other hand, when specifying the position within the range of 100 km square, the area code can be omitted because every position has the same 5-digit area code.

A quadrangular area divided by a grid of 100 m, 10 m, or 1 m is specified by an n-digit number indicating the position in the north-south direction (n is an integer) and an n-digit number indicating the position in the east-west direction. . This 2n-digit number may be referred to as MGRS coordinates. For example, the UTM grid coordinate of the region including the position indicated by the arrow in FIG. 4 is “886-355”. In the example of FIG. 5A, the coordinates “34 ° 22′2.6 ″ north latitude and 133 ° 55′43.4 ″ east longitude” expressed in latitude and longitude are expressed as “53SME 015-034” in UTM grid coordinates. Is done.
When the grid interval is 100 m, the UTM grid coordinates are represented by a 6-digit number with n = 3. When the grid interval is 10 m, the UTM grid coordinates are represented by an 8-digit number of n = 4, and the UTM grid coordinates when the grid interval is 1 m are represented by a 10-digit number of n = 5. .

  Thus, the UTM grid coordinates represent an area including a specific position (point), and the accuracy is determined by the grid interval (100 m, 10 m, or 1 m). When the number of digits of the UTM grid coordinates is 6 digits such as “015-034”, an area of 100 m square can be specified, in other words, the accuracy is 100 m. When the coordinates are 8 digits (4 digits + 4 digits), the accuracy indicates a 10 m range, and when the coordinates are 10 digits (5 digits + 5 digits), the accuracy indicates a 1 m range. If the number of digits of coordinates is increased, the position can be specified with high accuracy, and the number of digits of coordinates can be reduced when high accuracy is not required.

When the current location is expressed in latitude / longitude, for example, in the case of 5 digits, the integer part requires 3 digits, so the number of digits after the decimal point is 2 digits. Since 1 degree of latitude and longitude is about 111 km (40000 km / 360 degrees), the precision is about 1.11 km with two digits after the decimal point. Using up to 4 digits after the decimal point (ie 7 digits in total) gives an accuracy of about 11 m.
In other words, when specifying a location by latitude and longitude, it becomes a character string of 7 to 7 digits, and if a person communicates verbally, there is a risk of causing a transmission error.
For the reasons described above, it is extremely effective to use grid coordinates. In particular, in UTM coordinate values, the combination of 4 digits-4 digits makes the latitude and longitude the same precision as 7 digits-7 digits.

  The UTM grid coordinates have the advantage that the amount of information is small and the expression is simple compared to the case where the position is expressed by latitude and longitude. In the example of FIGS. 5A and 5B, the area code “53SME” can be omitted and the coordinates can be expressed as “015-034”, but the position can be specified with an accuracy of 100 m by this 6-digit number. . Since the coordinate structure is simple, it is particularly excellent in accuracy and convenience when transmitting from person to person, and is useful when, for example, the position is transmitted by telephone or wireless. If a UTM grid map and UTM grid coordinates are used, even a person who does not know a place name or address notation (for example, a lot number) can easily identify and grasp the position. Place names and address notations are difficult for people outside the region in areas with difficult-to-read place names or complex administrative divisions. For this reason, it is preferable to use a method that does not rely on a place name or address when a person engaged in rescue activities or the like in a disaster area represents a specific position in the disaster area when a disaster occurs. In particular, in the case of a wide-area disaster or emergency lifesaving in which support dispatch occurs from within or outside the prefecture, a method that does not use a place name or address is suitable. UTM grid coordinates can be expressed as a very effective tool for transmitting the position because the position can be expressed with a few digits.

As shown in FIG. 3, in this monitoring system 1, since the position of the user 7 is transmitted to the window server 6 in UTM grid coordinates (see step S7B), even if the user 7 is in a mountainous area having no place name or lot number, the user 7 position can be conveyed accurately.
By the way, the notification to the window server 6 in step S7B is based on the premise that the wearable device 2 can communicate with the window server 6 via the gateway device 3, and is always communicable in the case of a mountain disaster or a natural disaster. Is not limited.
Therefore, in the present embodiment, when the wearable device 2 determines that there is a physical abnormality, the control unit 11 of the wearable device 2 maintains (controls) the display unit 16 in at least a display state that notifies the current position.

More specifically, as shown in FIG. 3, in the monitoring system 1, when it is determined that communication is impossible in the process of step S <b> 5 </ b> B, the wearable device 2 performs the current position notification process under the control of the control unit 11. (Step S10B). The inability to communicate is not limited to inability to communicate between the wearable device 2 and the gateway device 3. Even if communication between wearable device 2 and gateway device 3 is possible, if communication between gateway device 3 and health management server 5 or window server 6 is not possible, it is determined in step S5B that communication is impossible. May be.
FIG. 6 is a flowchart showing the current position notification process.
The control unit 11 of the wearable device 2 first controls the display unit 16 to display the UTM grid coordinates indicating the position of the user 7, vital information, and wearer information stored in the storage unit 14. The display unit 16 is intermittently driven (step S21B). Thereby, even if the user 7 is in a low consciousness level, it can be communicated to others by the UTM grid coordinates indicating the current position of the user 7. Therefore, when the other person moves to a place where the telephone is located and makes a telephone call to the emergency medical service, it is easy to accurately convey the position of the user 7 with the physical anomaly using the UTM grid coordinates. In addition, since vital information is displayed, the other person can easily grasp the physical condition of the user 7. Further, since the wearer information is also displayed, the user 7 can be easily identified.

In addition, since the display unit 16 is intermittently driven (for example, repeatedly displayed and turned off at intervals of 1 second), power consumption is reduced, and blinking display makes it easier to draw the attention of others. At this time, the power consumption may be further reduced by extending the position information acquisition interval by the position acquisition unit 18.
Here, regarding the display of the UTM grid coordinates, vital information, and wearer information, since the display area of the display unit 16 is relatively small, the display is switched and displayed in a predetermined order rather than the method of displaying simultaneously. However, not only the switching display but various displays may be applied.

When the control unit 11 continues to periodically acquire the position information by the position acquisition unit 18 and obtains UTM grid coordinates corresponding to the latest position information, the control unit 11 displays the UTM grid coordinates on the display unit 16 (step S22B). Therefore, even if the position of the user 7 moves due to sliding down after the user 7 falls during the mountain movement, the accurate position of the user 7 can be notified.
Moreover, the control part 11 judges whether position information cannot be acquired (step S23B). When the position information can be acquired (step S23B; NO), the control unit 11 monitors whether or not the acquired position information does not change for a predetermined period (step S24B).

If the state where the position information does not change continues (step S24B; NO), the control unit 11 proceeds to the process of step S21B at a predetermined interrupt cycle. Thereby, the display state which displayed the UTM grid coordinate, vital information, and wearer information is continued.
On the other hand, when the state where the position information does not change continues (step S24B; YES), the control unit 11 stops the acquisition of the position information (step S25B). In other words, when it can be determined that the position of the user 7 is not moving, the state shifts to a power saving state in which the power consumption is reduced by the amount to stop the acquisition of the position information, and the driving time of the wearable device 2, that is, the display time of various information Extend.

Further, when the position information cannot be acquired by the determination in step S23B (step S23B; YES), the control unit 11 continues to display the position information (UTM grid coordinates) acquired last and is not the latest position information. Is displayed on the display unit 16 (step S26B).
In this case, the control unit 11 monitors whether or not the position information cannot be acquired for a predetermined period (step S27B). If the position information cannot be acquired (step S27B; NO), the control unit 11 performs a predetermined process. The process proceeds to step S21B in the interrupt cycle. On the other hand, when the state which cannot be acquired continues (step S27B; YES), it transfers to the process of step S25B. Thereby, when the position cannot be acquired in a building or the like, the acquisition of the position information is stopped, and the driving time of the wearable device 2, that is, the display time of various information is extended by shifting to the power saving state.
In addition, when it transfers to the power saving state of step S25B, the state may be continued, or when a predetermined time elapses, the power saving state may be canceled and the process may proceed to step S21B. Further, the power saving state may be canceled when a predetermined operation for canceling the power saving state is performed on the wearable device 2. The above is the current position notification process.

In the above notification process, the control unit 11 causes the voice output unit 17 to read out the UTM grid coordinates by voice synthesis, or to give voice notification such as vital information or wearer information. Anyway. In addition, the control unit 11 receives an input of a print instruction from the user 7 or another person, and when the print instruction is input, print data for printing the display image is transferred to the printing apparatus 9 (see FIG. 2) existing in the communication range. It may be wirelessly transmitted and printed on a print medium.
In FIG. 3, the case where the current position notification process (step S10B) is performed when it is determined in step S1B that the body is abnormal and it is determined in step S5B that communication is not possible has been described. . For example, when it is determined in step S1B that there is a physical abnormality, the current position notification process in step S10B may always be performed.

As described above, the monitoring system 1 of the present embodiment allows the window server 6 from the wearable device 2 via the gateway device 3 when a physical abnormality of the user 7 who is a wearer of the wearable device 2 is detected. In addition to notifying the physical abnormality, the location information of the user 7 is notified. As a result, in an environment where communication is possible, it is possible to promptly notify the user 7 of a physical abnormality, position information, and the like, and it is possible for the user 7 to respond quickly to a lifesaving emergency.
In addition, since the location information is notified in UTM grid coordinates, which is a grid map coordinate system defined by international standards, even if the location is difficult to identify by location name or lot number (for example, mountainous areas or wilderness) It becomes easy to convey the current position of 7.

In addition, when the user 7 determines that the user 7 has a physical abnormality, the control unit 11 of the wearable device 2 controls the display unit 16 to a display state in which at least the current position is notified. It becomes easy to accurately convey the current position of the user 7 to others. In addition, the other person in this case can consider the person who accompanies the user 7, or the companion of the user 7.
In the present embodiment, the wearable device 2 alone converts the position information composed of the latitude and longitude acquired by the position acquisition unit 18 into UTM grid coordinates, so it does not depend on other devices such as the gateway device 3. UTM grid coordinates can be displayed. Accordingly, it can be used in an environment without a communication environment.

  Moreover, since the control part 11 of the wearable apparatus 2 displays the UTM grid coordinate which is the information which shows the user 7's present position, and the vital information of the user 7, when the user 7 judges that it is a physical abnormality, It becomes easy to accurately convey the current position and vital information to others. In this case, since the control unit 11 switches between the UTM grid coordinates and the UTM grid coordinates, each information can be displayed in a large size even if the display screen is small.

Moreover, since the control part 11 displays the wearer information which specifies the user 7 further, when the user 7 judges that it is a physical abnormality, it becomes easy to specify the user 7 easily.
Moreover, since the control part 11 drives the display part 16 intermittently, while reducing power consumption and extending drive time, it becomes easy to attract others' attention by blinking display.

In addition, when the user 7 determines that the user 7 has a physical abnormality, the control unit 11 of the wearable device 2 continues to acquire the current position and notifies the latest current position. Therefore, the user 7 moves by sliding down after the user 7 falls. Even in this case, the accurate position of the user 7 can be notified.
In addition, when the acquired current position does not change over a predetermined period, the control unit 11 of the wearable device 2 stops acquiring the current position. Therefore, when the user 7 does not move, the power consumption is reduced and the information display time is reduced. Can be extended.

Further, when the current position cannot be acquired, the control unit 11 of the wearable device 2 displays the last acquired current position and displays that it is not the latest acquired current position. As a result, it is possible to notify others whether the current position is the latest. In addition, when the current position cannot be acquired for a predetermined period, the control unit 11 stops acquiring the current position. Therefore, when the position cannot be acquired in a building or the like, wasteful power consumption is suppressed and various information is displayed. You can extend the time.
Moreover, in this embodiment, since the wearable apparatus 2 is provided with the electric power generation part 19 which produces | generates operating electric power, it can be used for a long period of time also in the condition without power supply environments, such as a mountainous area.

  The above-described embodiment shows a preferred embodiment of the present invention, does not limit the present invention, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the case where the position information detected by the wearable device 2 is converted into UTM grid coordinates and displayed is described, but the present invention is not limited to this. For example, the wearable device 2 may acquire the position information detected by the gateway device 3, and the acquired position information may be converted into a UTM grid and displayed on the wearable device 2. However, in this case, it is necessary that the wearable device 2 and the gateway device 3 can communicate with each other.

Moreover, although the above-mentioned embodiment demonstrated the case where the user 7 was a physical abnormality, the wearable apparatus 2 displayed vital information, the UTM grid coordinate which shows a present position, and wearer information, it is not restricted to this. If at least information indicating the current position is displayed, it becomes easier to convey the current position of the person having the physical abnormality to the other person.
Moreover, although the case where the wearable apparatus 2 was equipped with the communication function which transmits vital information and a present position was demonstrated, it is not restricted to this. For example, when the wearable device 2 has a communication function for transmitting vital information or at least one of the current position, and the control unit 11 cannot communicate with the communication function, the display unit 16 displays at least the current position. It is only necessary to control it. Thereby, even when communication is impossible, it becomes easy to accurately convey the current position of the wearer who has become physically abnormal to the other person.
Further, the gateway device 3 may also display at least one of vital information, UTM grid coordinates indicating the current position, and wearer information. In this case, the information to be displayed may be transmitted from the wearable device 2 to the gateway device 3.

  In the above-described embodiment, the case where the present invention is applied to the monitoring system 1 using the wearable device 2 has been described. However, the present invention describes that the wearable device 2 has at least the current position when the user 7 has a physical abnormality. As long as it is controllable to the display state for notifying, it can be changed appropriately. For example, although the case where the service providing server including the health management server 5 and the window server 6 is provided has been described, the service providing server can be appropriately changed.

  Further, the wearable device 2 may be configured as the wearable device 2 that does not have a communication function by omitting the short-range communication unit 15 and the like. As described above, the wearable device 2 can acquire vital information, current position, UTM grid coordinates, and wearer information only by this device 2. Therefore, even if there is no communication function, when the user 7 has a physical abnormality, it is possible to display the UTM grid coordinates indicating the current position. Thereby, it becomes easy to convey to others the present position of the user 7 who became a body abnormality with a simple structure.
