DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication device.

[0002]

2. Description of the Related Art With the development of medical treatment, it has become possible to treat various illnesses which have been regarded as fatal in the past, and the people tend to have a longer life. With the increase of old people, so-called,
The problem of the elderly with dementia has been highlighted as a social problem. The problem is that the elderly have uncontrollable unconscious behavior due to their mental weakness while having enough physical strength to walk around. At home, the elderly sleep outside the house during the night when the family sleeps, causing damage such as traffic accidents, and in the facilities of elderly people, there are cases where they are sneaked into dangerous facilities such as boiler rooms and injured. is there. The trouble is that the old man may be playing in a hide-and-seek game and hide behind the scenes, and searching for a demented old man, who can be called the hide-and-seek old man, can be an unexpected difficulty. Conventionally, as a means of monitoring such a wandering old man or a hide-and-seek old man, only a bell was attached to the body of the old man. For this reason, emphasis was placed on measures to restrict behavior. The mainstream restrictions were to lock the room or tie the old man's body to furniture with a string.

[0003] When a demented elderly person is considered as one moving object, it is conceivable to apply a navigation system using GPS to confirm the current position of the moving object and to monitor the movement trajectory. It seems that the purpose is fulfilled by installing both a GPS-based position recognition device and a communication device for communicating the position information to the monitoring station to the elderly, but the device is turned off or the radio wave from the satellite It is difficult to capture if you go out of reach. It is also powerless if the device is removed by the elderly or by others. Although a navigation system using a PHS can be applied to this purpose, it has a similar problem.

[0004]

Restricting the behavior of the elderly with dementia by the above means puts a great mental burden on the person and the people around him. Restrictions on keys and cords seem hesitantly brutal as humane, so hesitate and win. It is often not good for elderly people with dementia who actually take actions that cannot be controlled only at a certain moment to continue to be subjected to humiliating restrictions during most of the time when they are acting with normal judgment.
On the other hand, there is also an example in which the door was locked and the person fell out of the window on the second floor to get out of the window. The surveillance by the bells is very narrow, and the elderly cannot help themselves if they are devised or removed so that they do not emit sound.

SUMMARY OF THE INVENTION A mobile communication device according to the present invention has a function of periodically confirming that the mobile communication device is fixed to a mobile object in a mobile communication device having a position recognition function. That the mobile communication device has a function of periodically confirming that the mobile communication device has a fixed position. In addition to the fact that the aircraft is fixed to the mobile unit, when the mobile unit behaves under specific conditions, the surrounding fixed communication station automatically displays a warning, or has a position recognition function In the mobile communication device, in addition to the fact that the mobile communication device is fixed to the mobile object, the PHS power is supplied by a directional antenna attached to a specific part of the mobile object in a specific direction. Characterized by receiving a.

[0006]

The mobile communication device according to the present invention is equipped with a position recognition device using a radio wave for a PHS telephone or a position recognition device such as a GPS, so that the position information of the mobile body itself is obtained and the position information is obtained. In addition to the system in which the PHS function itself or other communication means is used to contact a supervisor or to automatically take a coping action when certain conditions are met, the mobile communication device By regularly monitoring that the moving object is fixed to the moving object, the present embodiment has an effect of definitely grasping the current position of the moving object.
As the fixing confirmation means, when using an acceleration sensor, the moving body is fixed to the moving body by periodically checking whether the vibration pattern is unique to a specific object such as a person or a wheelchair. Recognize. When the mobile station performs an action under a specific condition and the surrounding fixed communication station automatically displays a warning, the condition is stored in the fixed station in advance and the condition is met. , Characters are displayed on the display screen of the fixed station, or a warning is issued with a siren or flashlight. When a PHS radio wave is received by a directional antenna attached to a specific part in a specific direction, the recognition of the fixed communication device that is communicating the PHS radio wave and the communication device that is used for the mobile object. Obtaining both information about the direction can improve the accuracy of position recognition of the moving object. For example, even if a fixed communication station exists in a direction in which the directional antenna does not face, communication with the directional antenna cannot be performed. In that situation, the directional antenna is facing without recognizing the fixed station. Recognize distant fixed stations. The farther the received radio wave becomes, the more it is recognized that it is far from the weakness. Since the moving body faces various directions, the fixed stations that can be detected by the directional antenna change one after another, and distance information from various fixed stations can be obtained. Thus, the location of the moving object can be accurately recognized.

FIG. 1 shows an embodiment corresponding to claim 1 of the present invention. It is an example of a mobile communication device 1 having a position recognition function for monitoring a wandering elderly person. It is a method of fixing it to a person's arm. FIG. 1 illustrates a form in which the flashlight 3 and the speaker 4 are provided. The end provided with the push button is furthest from each other. The mobile communication device has an antenna 5 for recognizing a position by communicating radio waves of a PHS (personal telephone). This antenna uses an omnidirectional detection type. ID at position shown
Display 6 is made. This ID display uses a liquid crystal display and displays the ID number as needed. As an example of the ID number, a member number of the elderly person is used in a facility for the elderly, and in the case of an elderly person who is being cared for at home, it is a telephone number of a family member who is caring. The ID display is displayed as needed. For example, when the old man wanders out of the house while wearing the mobile communication device, the ID display unit performs the ID display while flashing brightly. At this time, a message such as "Please contact XX (the telephone number is as follows)" may be added, etc. This mobile communication device is rounded in the form of FIG.

Here, an actual use form of the mobile communication device of FIG. 1 will be described. In a nursing home, the mobile communication device is mounted in a specific room such as a staff room.
This room is a room where the staff stays for 24 hours, and it is very unlikely that a wandering elderly person will enter without knowing it. In this room, the mobile communication device 1 is wound around the arm of the old man. Then, the switch is operated by finally pressing the push button 2. This mobile communication device does not include a switch for stopping the operation. The power consumption is kept low so that the battery operates for about one month. Then, in order to replace the battery, the wound communication device must be removed from the arm. This communicator is set so that it cannot be removed from the place other than the staff room unless 10 minutes have passed since the push button was pressed. This push button also functions as a telephone call switch from the mobile communication device, and when the push button is pressed, the current position information recognized by this mobile communication device is automatically transmitted to the observer and then The surrounding scenery and sound are also set to be sent continuously. The scenery and sound are acquired by a small CCD camera or microphone provided. Illustrations of these small CCD camera and microphone are omitted. A fisheye lens is attached to the small CCD camera, and a wide range of scenery can be obtained as image data. When the push button is pressed, the observer first determines whether the transmitted position information, scenery, or sound is normal. If an old man who is supposed to be in a facility is on a general street, it is an abnormal situation, and a person will be dispatched immediately to rescue the old man. At the same time, it flashes a flashlight to alert the people around the old man, and from the speaker, "I am leaving the staff to protect this old man, so please guide me to a safe place and protect it." The message of the content is sent. The scenery and voice are also important for detecting an abnormal situation. Since many wandering elderly people are hit by cars, it is especially important to pay attention to whether or not the noise of cars is nearby. It is very important to alert the driver by flashing the flashlight when the car is noisy. When the push button is pressed, the old man is trying to remove the mobile communication device.
If the watcher determines that it is important to take measures to prevent the removal even after the elapse of the minute, the permission to remove the connection is revoked using the call function. This command is set so as to be given priority over the push button command. The determination as to whether or not the room is inside the staff room is made using a position recognition system using PHS radio waves provided by the user.

The mobile communication device shown in FIG. 1 periodically sends the current position information to the monitor at intervals of 5 minutes. The observer checks the trajectory with a personal computer, and if a dangerous state or a dangerous state is likely to occur, dispatch the staff quickly and guide the elderly to a safe place by telephone function from the speaker. .

The second aspect of the present invention will be described with reference to FIG. FIG. 2 shows an example of nursing a wandering elderly person at home. An old man 8 with the mobile communication device 1 attached to his arm is about to go out of the house. Inside this house, a fixed communication station 9 having a weak output and a communication effective radius of 5 meters is mounted near the ceiling within 3 meters from the entrance. A sensor mat 10 is laid at the entrance. In this sensor mat, a pressure sensor is embedded, and when a person rides on the pressure sensor, the presence of a person can be detected by weight. When the sensor mat detects the weight, a monitoring monitor (not shown) composed of a personal computer is activated and automatically communicates with the mobile communication device to detect its location. GPS may be used to confirm the position, but the location may be detected from the intensity of radio waves from each fixed station of the PHS. In the case of FIG. 2, the position is detected from the intensity of the PHS radio wave. And in this home, door 1
The fixed communication station 9 having the low output described above is installed in order to improve the detection position accuracy near the position 2. When the position of the mobile communication device (that is, the elderly) is automatically checked from a personal computer based on the detection of the weight of a person by the sensor mat, the fixed communication station 9 and the mobile communication device 1 communicate (communication radio waves 11 are used). It is presumed that the elderly are trying to get out of the entrance door. In this case, it is set to report to the family member or to the security company that has contracted or the neighborhood.

If the weight is not detected by the sensor mat, the personal computer communicates with the mobile communication device to check the location of the mobile communication device every minute. If the position is not within the preset position range, the same notification is made as an emergency. The mobile communication device is provided with an acceleration sensor, and continuously monitors the degree of vibration of the mobile communication device and accumulates it in a memory. By analyzing the record of the vibration, it is determined whether the mobile communication device is properly attached to the arm. A person's arm moves unconsciously considerably. If it has not moved for a minute, it is presumed that it has been removed from the old man's arm and placed somewhere on the desk. In this case, an emergency situation is dealt with at the time of the regular monitoring (every minute). At the time of removal by bathing or the like, by inputting a password stored by a family member, it is possible to temporarily change settings so that even if removed for 20 minutes, it is not regarded as an abnormal situation. By adopting such a mechanism, the mobile communication device is apparently free to be removed, and has an effect of reducing the mental pressure of the old man wearing it.

The mobile communication device may be provided with a health management sensor such as a pulse meter, a sphygmomanometer, and a thermometer in addition to the acceleration sensor. This record is organized and recorded on the personal computer, and when the value exceeds a preset standard value, it is handled as an emergency.

FIG. 3 shows a second embodiment of the present invention. The mobile communication device 1 'is wrapped around the waist. This communication device is also provided with an acceleration sensor. When the communication device is attached to the elderly person 8, it is expected that a certain level of vibration is expected. Is done. It has a thin and stuffy structure so that it can be worn even during sleep so that there is little discomfort when wearing it. Specifically, the side that is surrounded by the curved surface and that contacts the body is provided with minute unevenness so that it does not adhere. This mobile communication device has a function of determining the current position from the type of PHS radio wave (specifying a fixed communication station) and its strength. The calculation function is provided in the communication device itself. In calculating the position, the number of steps counted by the acceleration sensor is also referred to. The walking distance is estimated by inputting personal data such as the stride of the elderly person in advance. Based on the vibration mode detected by the acceleration sensor, it can be determined whether walking is normal or slow. At the time of going to bed, a state such as turning over can be estimated. It also has the function of judging the lightness of sleep of the elderly from the movement of the body at bedtime and narrowing the interval of regular monitoring when the sleep becomes lighter. The old man gets up from a sleeping position in order to wander, so monitoring so that this moment is not missed can prevent danger in advance. By monitoring this moment,
For example, it is possible to cope with a case where an old man is going to the bathroom with normal consciousness. At that time, the lamps in the corridors and toilets are set to be turned on automatically. By analyzing the vibration detected by the acceleration sensor, for example, it can be estimated that the old man is on a train. If a vibration peculiar to the train is detected, it is determined that the moving ability is very high, and the program of the personal computer is set so that the monitoring is performed frequently and the response in the traveling direction is prepared.

FIG. 4 shows an embodiment corresponding to claim 3 of the present invention. An elderly person 8 wearing a mobile communication device is drawn out of the house 13 due to wandering habit and heads for a road with heavy traffic. A fixed communication station 9 'capable of communicating with this mobile communication device is installed on a telephone pole at the position of an alley 14 shown in the figure. When it is detected that the old man 8 has left his home, he or she is alerted to the car 15 running on the road by means such as flashing of a flash light or a red light. As an example of a means by which the fixed communication station detects the wandering elderly, a very weak radio wave is constantly transmitted from the mobile communication device worn by the elderly, and then the user goes outdoors and views the fixed communication station from the fixed communication station. It is set in advance that the radio wave arrives at the station when the user goes to a place where there is no obstruction and the radio wave reaches the station so as to operate the flashlight or the like.

A mobile communication device according to a fourth aspect of the present invention will be described with reference to FIGS. FIG. 5 schematically depicts a PHS fixed communication network. Radio range 1 from each fixed station of fixed communication station network 16 of a certain operating company
7 and the radio wave reach area 17 of the fixed communication network 16 'of another operating company are drawn with different hatchings. When the old man 8 is wandering around the city 18, the mobile communication device 1 "(FIG. 6) worn by the old man can communicate with the fixed stations of both the operating companies.

The old man depicted in FIG. 5 is wearing the mobile communication device 1 "shown in FIG. 6. A torso belt 19 for wrapping around the waist and a metal fitting for fixing it. It is provided with a buckle 20 and a directional antenna 21 is mounted so that its directivity is directed outwardly.The detection range 22 is the direction shown in the figure.The detection distance is 100 meters in a viewable environment. The mobile communication device 1 "is mounted so as to face the back of an old man. That is, the detection range is in the direction of the back of the elderly person when standing.
This mobile object detector has a function of receiving radio waves of both operating companies in FIG. Since there is directivity, even if it is a nearby fixed communication station, it will not communicate if it is outside its detection range (for example, on the ventral side). When an old man changes direction, the fixed communication station with which he or she communicates changes frequently. Since this communication is used to confirm the position of the user, the communication is completed in about one second. From the viewpoint of the movement of the elderly person, it is possible to communicate with one fixed communication station from the start to the end of communication. In this way, the position confirmation accuracy is improved by communicating with a plurality of fixed communication stations and recognizing the radio wave intensity while being at one position.

[0017]

According to the mobile communication device of the present invention, even if it is attempted to remove it by the person who wears it, it can be prevented or it can be detected from a remote place. The accuracy of position detection, which is a problem when utilizing a local wireless network prepared for communication such as PHS, is also improved. If the mobile communication device is provided with health management sensors, health management can also be performed. Equipped with a sensor for when the diaper gets wet enables efficient management on the welfare side. In the present specification, wandering elderly people have been mainly described. However, the present invention is not limited to this example, and can be used for helping a child to attend a cram school (electronic guardman). There is a danger of being kidnapped on the way home from cram school and home on a dark night road. To prevent kidnapping, you must return home through a defined safe route, but many children do not follow the defined return route. In order to make such a child follow a safe return route, a private school lends the mobile communication device of the present invention to a student of the private school and wears the mobile communication device to return home. The behavior is then monitored both at the cram school and at the child's home. The surveillance puts emotional pressure on your child to follow your return home route, and even if there is a sweet temptation of the kidnapper, you can interrupt the conversation with the mobile phone's built-in call feature. You can block it with a flashlight or a siren. It is very difficult to remove the mobile communication device or stop its function, which is a deterrent to crime. It is also effective when managing the behavior of visitors and internal staff at research institutions that value confidentiality. The accessible area should be different for each individual, which is effective for managing the range of activity at the individual level. It is also effective for entrance and exit management at dangerous facilities. For example, if an accident occurs at the facility and a worker who has been left behind must be rescued, the place where the worker is left can be reached without waste. It is also possible to obtain information such as injuries by the communication function of the mobile communication device, or to infer the situation of the worker from the vibration mode when an acceleration sensor is provided. Given life first, it is a very difficult decision to put rescue stakes at risk to rescue victims who are already dead. The auxiliary data is used to determine whether to proceed to rescue at that moment or to prioritize work such as fire suppression or the like to improve the environment even slightly before proceeding to rescue. This communication device is effective even if a healthy person wears it in daily life. The effect of protecting themselves from crime can be expected as in the case of returning home from the cram school. It is also effective that a hotel lends the communication device of the present invention to a guest as a business to which the communication device is applied. Some hotels located in the downtown area are dangerous when entering around the hotel. If a guest is equipped with a communicator of the present invention that is programmed to warn him of entering this area, the guest does not have to uselessly enter that area. It is a feature of the present invention that if it is known that the person wearing the mobile communication device cannot remove or stop the operation without permission, he / she wears it only by wearing it. It is much safer than a person who doesn't have it. You can also expect an evidential function to objectively prove your own actions. For example,
If you become a party to a traffic accident, you can prove your own behavior pattern immediately before the accident. It is important as evidence that it is impossible for a person wearing a mobile communication device to remove or stop operation without permission. It is possible to apply such as discounting automobile insurance premiums on the assumption that the user wears the mobile communication device. If the user wears the mobile communication device of the present invention, he or she will naturally take careful actions, and the accident rate is expected to decrease. The mobile communication device may be lent to a subscriber by an organization such as an insurance company.
