Description

The present invention relates to watching a person who lives alone regardless of age or health condition.

Conventionally, a monitoring system for living alone using a human sensor or a monitoring camera is known.

Japanese Patent No. 5108161

However, there are many things that give a sense of being monitored to the person being watched over.

This is because human sensors such as passive infrared detectors and surveillance cameras are designed to monitor abnormalities while detecting the movement of the person being watched over, so it is necessary to always install it in a location that is visible to the person being watched over. is there.

In addition, in a single life watching system using a surveillance camera, there is a problem that the watching target person's video can be forcibly watched, and the privacy of the watching target person is infringed.

In order to solve the above-mentioned problems, a radio transmitter and receiver are installed in a room where the person spends the most time in the watched person's residence and is not visible to the watched person. Radio wave is transmitted at the frequency of, and the received signal strength of the radio wave transmitted from the radio wave transmitter is acquired by the radio wave receiver in units of 0.1 second or less. The acquired received signal strength, the acquisition time, and the unique ID assigned to the radio receiver are transmitted to the server device.
Every time the person being watched moves in the room, the received signal intensity at the installed radio receiver changes, so the activity of the person being watched is recorded quantitatively while watching the change.

The server device arranges the received signal strength stored for each person to be watched on the time axis in real time, totals the received signal strength at a predetermined time and time interval, and compares it with the same past time determined in advance. Then, determine whether it is abnormal.

When the server device compares received signal strengths and detects anomalies, as additional information, the area where the watching target person lives and the other watching target person living in the same area or the other watching target person defined in advance The received signal strength is compared to determine whether it is abnormal.

When the server device compares the received signal strength and detects an abnormality, it takes into account the weather information (sunshine hours, precipitation), outdoor temperature and outdoor humidity information of the area where the person to be watched lives as additional information. Determine if it is abnormal.

As a result of the comparison, if the server device regards it as abnormal, the server device notifies the e-mail address, social network service, and the like registered in advance for the watch-related parties.

According to the present invention, it is possible to monitor without being given a sense of being monitored to the person being watched over, and the accuracy of the notification at the time of abnormality is improved, so that the person being watched over and the person concerned with the watch receiving the notice (watching) It is an object of the present invention to provide a monitoring system that is open to unnecessary safety confirmation due to misinformation.

The present invention relates to an abnormality detection of a watching safety confirmation system for watching without giving a sense of being monitored to a watching target person. In other words, as a human activity, the radio wave receiver acquires the received signal strength of radio waves emitted from radio wave transmitters that are installed in the room and are not visible to the target person, and aggregates them at predetermined times and time intervals. It is a monitoring system that detects an abnormality early while reducing false alarms by comparing and further adding abnormality determination additional information.

Hereinafter, as a specific form for implementing this algorithm, an example will be described with reference to the drawings. FIG. 1 shows a monitoring system for living alone. The watching system includes the server device 10, the radio wave transmitter 20 and the radio wave receiver 40 installed in the watching target person's house, and the smartphone 30 owned by the watching related person (the related person who should watch the watching target person, the abnormality notification delivery destination). Are connected by an external communication line network such as the Internet line.

The server device 10 accepts information transmitted from the radio receiver 40 of the person being watched over via an external communication line network such as the Internet line. The received information is recorded in the database in the server device 10. In addition, the server device 10 has a web function, and can disclose information stored in the database of the person to be watched to an overseeing person via an external communication line network such as the Internet line.

The radio wave transmitter 20 and the radio wave receiver 40 are installed in the watched person's residence in a place where the person who watches the watched person cannot see the longest time. The radio wave receiver 40 has a function of connecting to an external communication line network such as an Internet line, and can receive information directly to the server device 10 when receiving the received signal strength from the radio wave transmitter 20. It is.

In order for a watch-related person (a person who should watch over the person being watched over) to use the watch system, the smartphone 30 is necessary to receive a notification when an abnormality is detected.

Next, the flow of the monitoring service using the monitoring system will be described.

The application for the use of the monitoring service is a person concerned with watching (a person who should watch over the person being watched over). The watching-related person registers the watching target person's home address and the abnormality notification delivery destination in advance in a database in the server device 10 via an external communication line network such as the Internet line at the time of the watching service contract.

The radio receiver 40 is given a unique ID that cannot be changed throughout the lifetime, and after being installed in the monitoring target person's house, the radio receiver sensor unique ID and an abnormality notification contact address of the watching party are stored in the database in the server device 10. With a string.

The abnormality notification delivery destination refers to an email address, a social network service, or the like to be notified when the server device 10 determines that an abnormality has occurred by adding information transmitted from the radio wave receiver 40 and abnormality determination additional information. .

Based on the unique ID of the radio wave receiver 40 determined to be abnormal, the server device 10 searches the database for an abnormality notification contact and notifies the contact. The above is the flow of the monitoring service using the monitoring system.

A flow in which the server apparatus 10 in the embodiment of the present invention monitors an abnormality is described in the flowchart of FIG.

After confirming the received signal strength acquired from the radio receiver 20, the radio receiver 40 transmits the acquired time and the unique ID of the radio receiver to the server device 10. (Step 510)

The server device 10 is in a state of always waiting for data reception from the radio wave receiver 40. When data is received (Yes in step 520), the data value is stored in the database in the server device 10. (Step 530)

After saving in the database in the server device 10, the weather (sunshine hours, precipitation), temperature, and humidity information for the current time in the same area based on the monitored person's home address information registered in advance by the watchers when the watch service is contracted Is obtained from the information providing service 50 such as weather / temperature / humidity, and is also stored in the database in the server device 10. (Step 540)

Next, the server device 10 checks with a built-in clock in the server device 10 whether or not the time interval is set in advance for each person to be watched in advance. If it is not time (step 550, No), the process returns to the determination state of whether or not data has been received from the radio receiver 40 (step 520), and if data is not transmitted from the radio receiver 40 (step 520, No). ) Check the built-in clock again in the loop state.

If the internal clock of the server device has a predetermined time interval and time (step 550, Yes), the process proceeds to a comparison process that takes into account additional information, and if even one of the comparison results is determined to be abnormal (step 560, Yes), the weighting of the additional information is adjusted to determine the abnormality flag value. (Step 570)

It is determined whether or not the abnormality flag value exceeds a predetermined threshold value for each watching user. If it exceeds (Yes in step 550), the abnormality is monitored and registered in the abnormality notification contact information of the related person. Contact your email address and social network service. If the value is below the threshold value, the process returns to the determination state as to whether data has been received from the radio wave receiver 40. (Step 520)

If an abnormality is reported, then the time interval to be compared is shortened or the next confirmation time is confirmed. In some cases, the threshold value of the abnormality flag is corrected. (Step 590) The above is the flow in which the server apparatus 10 monitors abnormality.

The flow in which the server apparatus 10 according to an embodiment of the present invention determines abnormality by adding additional information is described in the flowchart of FIG.

As the first comparison process, the received signal strength of the radio wave receiver 40 stored in the database in the server device 10 is set to the unique ID of the radio wave receiver 40 linked to the person to be watched, the past time determined in advance, Extracted at a time interval, and compared with that of the current time, if it is less or equal, or greater than a predetermined value, it is regarded as abnormal (step 610, Yes), and an abnormal flag is added. (Step 660) On the other hand, other than the above, the process proceeds to the next comparison process. (Step 610, No)

As the next comparison process, weather information (sunshine hours, precipitation) stored in the database in the server device 10 is extracted at a predetermined past time and time interval, and is smaller than that of the current time, or If equal and greater than a predetermined value, it is regarded as abnormal (Yes in step 620), and an abnormal flag is added. (Step 670) On the other hand, other than the above, the process proceeds to the next comparison process. (Step 620, No)

As the next comparison process, the temperature information stored in the database in the server device 10 is extracted at a predetermined past time and time interval, and compared with that of the current time, it is determined in advance that it is smaller or equal. If it is larger than the above value, it is regarded as abnormal (step 630, Yes), and an abnormal flag is added. (Step 680) On the other hand, other than the above, the process proceeds to the next comparison process. (Step 630, No)

As the next comparison process, the humidity information stored in the database in the server device 10 is extracted at a predetermined past time and time interval, and compared with that of the current time, the humidity information stored in the database is determined in advance. If the value is larger than the above value, it is regarded as abnormal (step 640, Yes), and an abnormal flag is added. (Step 690) On the other hand, other than the above, the process proceeds to the next comparison process. (Step 640, No)

As a final comparison process, the received signal strength of the radio receiver 40 stored in the database in the server device 10 is watched and the unique ID of the radio receiver 40 linked to the target person and the past time and time set in advance. Extracted at intervals, and similarly, compared with that of a plurality of other predetermined watching subjects, if it is less or equal, and more than a predetermined value, it is regarded as abnormal (step 650, Yes) Add the abnormal flag. (Step 700) On the other hand, other than the above, the comparison process is terminated. (Step 710) The above is a flow in which the server device 10 determines abnormality by taking into account additional information.

As described above, the monitoring system for living alone according to the present invention increases the accuracy of the notification at the time of abnormality without giving the monitoring target a sense of being monitored, and the monitoring target person and the monitoring related person who receives the notification (watching the monitoring target person). Should be released from useless safety confirmation due to misinformation, and is useful for enabling effective monitoring from remote locations. The possibility is high.
