BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below based on the drawings. In the description, all the drawings described in the examples are drawn as schematic diagrams for explaining the present invention, and means and configurations that are inevitably and naturally provided are omitted. . Also, the dimensions and shape are not strict. Therefore, unless otherwise specified, the dimensions, materials, shapes, relative arrangements, etc. of the constituent elements are not intended to limit the technical scope of the invention.

In the present invention, the wheelchair is assumed to be a manual or electric wheelchair mainly for the elderly and the disabled, but not limited to the wheelchair defined under the Road Traffic Law, and can be used for watching, monitoring, nursing care or rehabilitation. It is also possible to apply it to senior cars used by users who need it, rowing and foot rowing wheelchairs for rehabilitation, electric carts, bicycles, tricycles, and the like.

FIG. 1 is an explanatory diagram showing an example of a communication network according to an embodiment of the invention. A user communication terminal (or terminal device) 1 on the wheelchair user's side and a supervisor communication terminal (or terminal device) 2 on the supervisor's side are connected to a cloud server 4 via a communication network 3 . This communication network 3 may be any wireless communication line such as a telephone line or an Internet communication line such as WiFi, but is an LPWA (Low Power Wide Area) network suitable for IoT (Internet of Things). It is desirable to use a communication method called LTE-M (Long Term Evolution for Machine-type Communication).

In the LTE-M communication system, the handover function does not interrupt communication even while moving, making it suitable for mobile communication. Therefore, it has advantages such as being sufficient with extremely small data communication capacity, being able to be designed with extremely low power consumption, and being able to update the firmware by communication (remote update). In addition, since it is configured to connect from the user terminal side to the cloud side only when necessary for IoT and intermittently every few minutes, it can be used at extremely low communication costs. Therefore, it is suitable as a terminal for wheelchair users of the present invention, and it is possible to configure a terminal device that is inexpensive, small, and can be used for a long time.

The user communication terminal device 1 is installed at a wheelchair position such as a handrail that is easy for a wheelchair user to operate. This user terminal device 1 can be easily attached and detached by a magnet or the like, and is constructed so that it can be detached and carried when the user leaves the wheelchair.

The user communication terminal device 1 has a transmission/reception section 5 and an output section 6 . The transmitting/receiving unit 5 is composed of a modulation/demodulation circuit (modem) adapted to the communication system, a communication antenna, etc. so as to communicate with the supervisor communication terminal device 2 and the cloud server 4 via the communication network means 3 . The output unit 6 outputs the received instructions and command signals as audio signals and optical signals, which are output and displayed by the speaker 7 or the lamp 8 .

The user communication terminal device 1 also includes a behavior detection sensor 9 . The behavior detection sensor 9 is composed of a position information GPS sensor, a gyro sensor, a compass sensor, an acceleration sensor, or an abnormality detection sensor that is a combination thereof. The GPS sensor acquires and transmits the location information of the wheelchair user. Also, the gyro sensor, compass sensor and/or acceleration sensor are used to detect the movement of the wheelchair or user, and act as an abnormality detection sensor for detecting accidents such as falls and collisions. When these action detection sensors 9 or some of these sensors are provided in the wheelchair body, the user terminal device 1 receives various sensor signals from these action detection sensors installed in the wheelchair body, An action detection signal may be transmitted.

Furthermore, this user terminal device 1 is provided with an emergency button 10, and in the event of an emergency or an emergency situation, the wheelchair user simply presses the emergency button to detect an abnormality as an abnormality detection sensor signal. It is configured to be able to transmit the situation. A safety confirmation button 11 is also provided for requesting safety confirmation from the supervisor side and for confirming that there is no abnormal situation on the user side.

On the other hand, the supervisor communication terminal device 2 on the supervisor side is mainly composed of an input section 12, a transmission/reception section 13, a display section 14, and the like. The supervisor is a caregiver, an attendant, a relative of the wheelchair user, or an administrator of a hospital or nursing care facility. , action conditions, life schedule, etc. are set, and instructions and orders are sent to the wheelchair user.

Behavioral standards for wheelchair users are basic restrictions on wheelchair use that take into account the characteristics of the user, such as the user's degree of recognition, level of care, degree of disability, rehabilitation status, and physical strength. and appropriateness of available wheelchairs (can use wheelchairs, cannot use wheelchairs, conditional use, manual or electric wheelchairs, need for constant companions, etc.), contact network for hospitals, fire departments, and relatives in the event of an emergency, wandering, or disappearance and so on. In addition, the action conditions are various conditions for using a wheelchair to act. These include rehabilitation items. A life schedule is a user's daily behavior pattern or a predetermined schedule, and includes, for example, meal times, drug intake times, rehabilitation times, and bedtimes.

The supervisor inputs, in advance, behavior standards, behavior conditions, life schedules, rehabilitation items, etc. that match the characteristics of the above-described user from the input unit 12 of the supervisor communication terminal device 2, and transmits the transmission unit 12 and the communication network 3. input to the action condition program 16 in the cloud server 4 via the This action condition program 16 transmits instructions and commands to the user terminal device 1 via the communication network 3 in accordance with the user's previously input and set use conditions regarding the use of a wheelchair. The wheelchair terminal device 1 has a GPS sensor and periodically transmits the position information of the wheelchair user. If the action condition is deviated from or is likely to be deviated, a preset caution signal (alert) or an action guideline (guide) by a voice signal is automatically issued, and the speaker 7 or the display means of the lamp 8 speaks It is programmed to be emitted as a signal or optical caution signal.

This behavioral condition program 16 is based on the characteristics of each wheelchair user, such as the degree of recognition, the degree of care, the degree of disability and rehabilitation. Conditions are set for individual behavior patterns, predetermined schedules, rehabilitation/health management items, etc., and monitoring and watching instructions are set and programmed in advance when the conditions are not met.

In setting the area range and travel route of such an action condition program, the condition is determined by determining the wheelchair accessible area and travel route on the map shown on the display 15 of the display unit 14 of the supervisor terminal device 2. It is used as an input and registered in the action condition program 16 on the cloud. On the wheelchair side, the GPS position information is acquired, and in setting the travel route, it is possible to configure so that travel navigation (action guideline) is transmitted to the wheelchair user by voice guidance.

In the action condition program 16, the GPS position information transmitted from the wheelchair user terminal device 1 is compared with the restriction conditions on the registered map, and if the user deviates or is likely to deviate from the area range or travel route, a warning is issued. Signals (alerts) and navigation guides (action guideline) such as destination guidance are transmitted to the user terminal device 1 and the supervisor terminal device 2 by a set program. This caution warning signal calls attention by flashing a lamp or the like together with an audio alert in the user terminal device 1 or the supervisor terminal device.

The means of transportation in the behavioral condition program 16 is conditional on buses, taxis, trains, etc. that are accessible by wheelchairs. In terms of weather conditions, it is possible to have a program that regularly notifies weather forecasts in conjunction with usage restrictions due to weather. In addition, the period of use and the time of use are set by setting a predetermined available date and time. Furthermore, as daily behavior patterns and schedules, the above-mentioned meal, medicine taking time, hospital visit schedule, etc. are set, and an alert signal or voice navigation guide is sent to return home or go to a predetermined place by a predetermined time. send. Such weather condition information and schedule information can be predicted in advance. It is configured to transmit a guide (action guideline).

This alert signal is a voice signal and a flashing light signal, and as the voice signal, a message is registered so that an instruction command signal is specifically voiced and output. For example, if it is out of the action range conditions, it will be "out of the area!" , "It's time to eat (medicine, rehabilitation, go home)!" It is desirable to be configured to provide navigation instructions such as directions and route changes. Various patterns of such voice alert signals are configured by combining various conceivable conditions in the action condition setting program.

In either case, when the wheelchair user deviates from the behavioral conditions or is likely to deviate from the behavioral conditions, the user terminal device 1 and the supervisor terminal device emit an alert signal to call attention to the user's attention, which is programmed in accordance with the respective conditions. 2. Upon receiving the alert signal, the user follows the instruction to change the travel route so as to meet the conditions, or to correct the route to a predetermined location. Furthermore, if the behavior condition is not met continuously, the alert signal is continuously transmitted to the user terminal device 1 until the condition is met. If the conditions are still not met after a lapse of time, an automatic program issues a voice signal to notify the emergency button 10 attached to the user terminal device 1.例文帳に追加When the emergency button is pressed, the monitor side recognizes the emergency alert signal displayed on the monitor terminal device 2, dispatches a rescuer according to the degree and characteristics of the user's disability, or dispatches a rescuer to a nearby police box or support center. Take steps to reach rescue from the center.

The action condition program 16 is set in advance to the extent that the action conditions by the wheelchair can be predicted according to the characteristics of the wheelchair user. Many of these behavioral conditions are set by the observer in consideration of the user's daily life routine, schedule, weather information and traffic information on the day of use, and are registered in the behavioral condition program 16 . Such an action condition program 16 lists conditions to be registered as a program table (monitoring chart). A wheelchair user can move freely without a supervisor's attendant within the set range of motion. In the present invention, even if the action conditions from the supervisor side are not met, the user is warned by issuing an alert signal or an action guideline using an audio signal or an optical signal, but direct guidance or movement of the wheelchair is forced. It is not intended to control

When moving in a wheelchair without an attendant, it is conceivable that various abnormal situations may occur even if the behavioral conditions are restricted. Therefore, in the user terminal device 1, a gyro sensor, a compass sensor and/or an acceleration sensor are provided as behavior detection sensors 9 for abnormality detection sensors. These various sensors work to detect accidents such as falls and collisions of wheelchairs and users. When an abnormality (accident) detection signal is sent from the action detection sensor 9, the action condition program 16 asks the user to press the safety confirmation button 11 by a voice signal to confirm whether or not there is an accident. However, the acquisition of the confirmation signal by the safety confirmation button 11 is confirmation of the user's consciousness recognition state, and regardless of the presence or absence of confirmation of pressing the safety confirmation button, the observer takes rescue measures. When the user presses the emergency button 10 or the safety confirmation button 11, and when the abnormality (accident) detection signal is transmitted by the abnormality detection sensor, the communication line is configured so that the signal is continuously transmitted by a constant connection instead of the usual intermittent communication. .

Furthermore, the present invention can be configured to include a health care program as the action condition program. This health management program sets rehabilitation and health management items for wheelchair users, and measures the amount of exercise associated with movement of the wheelchair. Such a function can be applied not only to the elderly and disabled people undergoing rehabilitation, but also to healthy people and athletes using the wheelchair rowing and leg rowing functions to manage their health and increase their physical strength. Using the GPS navigation data acquired by the behavior detection sensor 9 in the terminal device on the wheelchair side, the traveled distance is calculated, accumulated, and recorded, and compared with the characteristics of the wheelchair user acquired in advance, calorie calculation, muscle Health management data such as weight and fat mass estimation can be recorded in a health management program and used to improve health management and sports performance.

FIG. 2 is a flow chart showing the main flow regarding navigation of the wheelchair monitoring method according to the present invention. Grasping location information and performing navigation are the most important elements in wheelchair monitoring. On the monitor side, the wheelchair action conditions are set in consideration of the characteristics of the user based on the map displayed on the display 15 of the monitor communication terminal device 2 (step 1, hereinafter referred to as S1). are registered in advance in the action condition program 16 (S2). This action condition determines the range in which the user can move in the wheelchair based on the location, facility, etc., and is input and set in consideration of the user's characteristics (care level, recognition level, physical strength, etc.). Among the action conditions, the action area range condition can be set as a radius of several kilometers around the place of residence such as a house or facility, or set by entering an area or address. Navigation can also be performed by voice output to the side.

In this action condition setting step (S1), in addition to the action area range condition, transportation means, weather conditions, usage period, usage time, and life schedule are also set, registered in the action condition program 16 in the cloud server 4, Record (S2).

Positional information is periodically obtained from the wheelchair side by the GPS sensor provided in the user communication terminal device 1 (S3), and the positional information is transmitted from the terminal device 1 to the action condition program 16 in the cloud (S4). . In the action condition program 16, the position information of the wheelchair is constantly compared with the registered action conditions, and a pass/fail judgment is made as to whether or not the action conditions are met (S5). If the action condition is met in the acceptance/rejection determination step (S5), the monitoring is continued as it is. Also, if the action condition is not satisfied, an alert signal (first alert signal) is transmitted (S6).

The pass/fail determination of this action condition match is made in consideration of not only the action range based on the position information but also other registered action conditions. For example, as weather conditions, when bad weather is predicted, the action condition is rejected and an alert signal is transmitted. In addition, even when the conditions of the registered use time and life schedule are deviated, the behavioral conditions are restricted and a voice alert signal corresponding to the deviated conditions is transmitted. As described above, in addition to the content of the alert, the alert signal also includes instructions and instructions such as returning home and changing routes, etc., by means of voice signals. Also, even if the action range condition based on the position information is met, if the other conditions are not met, an alert signal is sent to the effect that the set condition is deviated each time (S6).

The transmitted first alert signal is received by the user communication terminal device 1 (S7), and similarly received by the supervisor communication terminal device 2 (S8). When the wheelchair user recognizes the alert signal and takes an action that matches the action condition according to the instruction or command, the position information obtained by correcting the regularly transmitted wheelchair position information is sent to the action condition program 16 in the cloud. (S9). The program 16 determines whether or not the action conditions are corrected and the conditions are met (S10). In the determination of the presence or absence of correction conditions (S10), if there is correction (Yes), it means that the behavior conditions are met, and monitoring and watching are continued.

If there is no correction (No) in the determination of the presence or absence of correction conditions despite the transmission of the first alert, it is still out of the action conditions. Then, the next alert signal (second alert signal) is continuously transmitted (S11). Like the first alert signal, this second alert signal is received by the user communication terminal device 1 (S12), and similarly received by the supervisor communication terminal device 2 (S14). When the wheelchair user recognizes the second alert signal and takes an action that matches the action condition according to the instructions and instructions, the corrected position information is transmitted (S13), and the action condition is met again within the program 16. (S15). If there is correction (Yes), it means that the action conditions are met, and monitoring and watching are continued as they are.

However, if the second alert is still not corrected (No), it is considered that there is a possibility of an emergency, so an emergency inquiry message registered in the action condition program 16 is issued (S16) and repeated. Continue to transmit the emergency signal by continuing the flashing of the light. This emergency confirmation message and emergency signal are received by the terminal device 1 on the user side (S17), and are simultaneously received by the communication terminal 2 of the supervisor (S18). The emergency inquiry message instructs to press the safety confirmation button 11 of the communication terminal 1, such as "If there is no problem, press the safety confirmation button!" or "If there is no problem, follow the driving route instructions!" .

The wheelchair user who receives such an emergency inquiry message presses the safety confirmation button 11 if there is no problem, and the action condition program confirms that there is no problem (S19). In response to this inquiry message request, the user presses the safety confirmation button 11, and if it is confirmed that there is no problem, monitoring and watching are continued again. Even if the safety confirmation button 11 is not pressed, it can be confirmed that there is no emergency when the wheelchair user changes the route according to a predetermined travel route or instructions. That's not what it means.

If the safety confirmation button 11 is not pressed and there is no reaction from the user, such as changing the route, the monitor side judges it as an abnormal situation, and considers the degree and characteristics of the user's disability and assigns a rescuer or an attendant. or take measures to go to rescue from a nearby police box or support center (S20).

These series of action condition programs are always in operation when the wheelchair is in use, start when the wheelchair is in operation, and end when the wheelchair is in use. This activity condition program is pre-programmed with weather information, time of use, and user's daily schedule, in addition to guidance on the range of activity and travel route for wheelchair users, and is used not only to limit activity conditions, but also , is used to transmit such information to the user communication terminal device 1 periodically.

In addition, the user communication terminal device 1 is equipped with a wheelchair abnormality detection sensor that is a gyro sensor, a compass sensor, an acceleration sensor, or a combination thereof, and these sensors detect collisions and falls of the wheelchair. . When the wheelchair collides or falls due to an accident or the like and the abnormality detection sensor is activated, an abnormality detection signal is immediately transmitted to the action condition program 16, an abnormality alert is notified to the supervisor communication terminal device 2, and the user communication terminal. A message such as "Press the safety confirmation button 11 if all is well!" is transmitted to the device 1. The monitor side judges the situation as abnormal, considers the degree and characteristics of the user's disability, dispatches a rescuer or an attendant, or takes measures to contact a nearby police box or support center.

In the present invention, the monitor mainly includes caregivers, attendants, relatives, and administrators of hospitals and nursing homes for wheelchair users. A watching community or the like may be provided with a supervisor terminal device and configured to watch over a wheelchair user as a community as a whole.

In the above-described embodiment, the monitoring system and monitoring method for the wheelchair user have been described mainly as software processing on the cloud side. They may be incorporated and executed, or they may be executed separately.

Various wheelchair behavior conditions transmitted from the behavior condition program 16 in the cloud server 4 in the present invention and responses transmitted from the terminal device 1 on the user side always require a two-way communication environment. Communication is possible by regular and intermittent communication, and the communication information is instructions, instruction information and voice information, and communication by communication lines such as LTE-M that reduces communication costs because of extremely small communication capacity. It can be configured with a small, lightweight communication terminal device using a network. Of course, since smartphones, which are the most versatile mobile communication terminals used in the market, are equipped with many functions of the present invention, a software program capable of communicating with the action condition program of the present invention is incorporated into the smartphone. It can also be used as a user communication terminal device.

In the present invention, wheelchair action conditions are set in advance according to the characteristics of the wheelchair user, and the user's action range, travel route, schedule, weather conditions, etc. are monitored, and when the action conditions are deviated from, an alert signal is sent. Occur. In addition, when an abnormal situation such as a collision or a fall occurs while the wheelchair is moving, the abnormal situation is automatically notified to the supervisor. Furthermore, if the wheelchair user experiences an abnormal situation, the operator is notified of the abnormal situation by pressing the emergency button. By applying such a monitoring system and monitoring method, it is possible to alert wheelchair users even if they are not always accompanied by an attendant or a nurse who is a monitor, thereby detecting and preventing accidents and detecting abnormal situations for users. It is possible to save labor and manpower for watchers because it is possible to prevent and prevent it. Furthermore, by incorporating a health management program, not only the elderly and disabled people undergoing rehabilitation, but also healthy people and athletes can effectively manage and monitor their health using wheelchairs.

As described above, by applying the present invention to the increasing use of wheelchairs, it is possible to automatically and periodically provide wheelchair users with guidance on their range of action and course of action, as well as various types of information, thereby reducing accidents caused by wheelchair users. It is possible to perform detection and prevention, and it is possible to save the labor and manpower of the watcher, and the industrial applicability is high.
