Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a life monitor system capable of monitoring the safety of an elderly person or a physically handicapped person living alone over a long distance.

[0002]

2. Description of the Related Art Conventionally, a living monitor system of this kind has been used to transmit information such as the operation of a predetermined electric appliance in the home, for example, the on / off operation of a hot water supply switch of an electric pot, to a dedicated signal transfer path or home. The information is transmitted to centralized management means located in the home using the internal power line, and the centralized management means records and manages operation information and the like. Then, at a predetermined time, the information recorded in the centralized management means becomes the destination data (telephone number) registered in the centralized management means in advance.
And send it along with information such as a code to identify the user to a monitor such as a personal computer installed in a clinic outside the home via a telephone line. It is possible to monitor the safety of disabled people. However, when information is transmitted from the central management means to the monitor means, if there is no operation information of the electric product, the transmission is not performed.

[0003]

However, the above-mentioned life monitoring system is not suitable for monitoring means outside the home.
It is impossible to determine whether there is no periodic transmission because there is no operation information of the electric product, or whether there is no periodic transmission because the electric product or the centralized management unit has failed for some reason.

[0004] Therefore, an object of the present invention is to provide a life monitoring system that can simplify transmission information and make it easier to more quickly determine the situation in a home to be monitored.

[0005]

In order to solve the above-mentioned problems, a life monitoring system according to the present invention records and manages information on electric appliances placed in a home by centralized management means.
In a life monitoring system for monitoring living conditions by transmitting the information to a monitoring means outside the home via a telephone line at a predetermined time, the centralized management means is provided with information recording means for the electric product, Detecting means for detecting information in the electric appliance information recording means at the time of transmitting information to the means, setting a transmission form to the monitor means based on a detection result of the detecting means, A number receiving means for receiving a caller telephone number notified from the exchange side of the telephone line is provided, and a storage means for storing a telephone number of a specific caller is provided. The telephone number received by the number receiving means and a storage means are provided. A specific caller is identified by comparing with the telephone number stored in the It is configured to determine the status of that home.

According to the life monitoring system, the central management means sets the transmission form to the monitoring means based on the detection result by the detecting means, while the monitoring means uses the telephone number by the number receiving means and the storing means. The system is configured so that the incoming call from the specific caller is identified by the telephone number notified when the incoming call is received from the line exchange side, and the status of the home to be monitored is determined by the incoming call form from the centralized management means. Information can be transmitted and received accurately according to the living situation at home.

In the life monitoring system, it is preferable that the form of transmission from the central management means is the number of call signals to the monitoring means. Here, the number of paging signals means the number of wavelengths in the waves of the paging signals. Also, this number means the number of wavelengths transmitted in one transmission operation from the transmitter side or the cumulative number of wavelengths transmitted within a predetermined time. In this case, the monitor means
It is preferable that the telephone line be automatically connected when the received caller telephone number matches the telephone number of the specific caller stored in the storage means and the number of call signals equal to or greater than a predetermined number is detected.

Alternatively, the transmission form from the centralized management means may be a transmission time of a call signal to the monitor means.

[0009] In this way, the necessary information to be transmitted to the monitor means can be quickly transmitted and received only by accessing the monitor means in a predetermined form via the telephone line.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a life monitoring system according to a first embodiment of the present invention. This life monitoring system includes an electric appliance 1 and a centralized management unit 2 installed in a home to be monitored, and a monitor unit 3 installed in a clinic outside the home. In the present embodiment, a home power line 4 is used as a signal transport path as a means for connecting the electric appliance 1 and the central management unit 2, and an exchange (not shown) is used as a means for connecting the central management unit 2 and the monitor unit 3. A wired telephone line 5, which is a normal public telephone line connected via the Internet, is used.

As shown in FIG. 2, the electric product 1 is a normal electric product comprising a load control circuit 7 and a display panel section 8 and a microcomputer 9 and a modulation / demodulation circuit 10 which also function as operation status detecting means. Is added. In the present embodiment, an electric pot 1A and a rice cooker 1B are illustrated as the electric products 1, but in addition to these, all electric products 1 used at home such as an air purifier, an air conditioner, and an electric vacuum cleaner can be used. Needless to say, it can be applied to.

The microcomputer 9 is provided with operation information by detecting that an operation switch provided on the display panel section 8 has been operated, and an electric appliance for every desired time such as every two hours by a built-in clock. 1 is transmitted to the modem circuit 10 as a predetermined signal wave. Also, it detects whether or not there is a reply from the central management unit 2 to the modulation / demodulation circuit 10, and retransmits the signal wave when the reply is not detected within a predetermined time by a built-in timer.

Here, as the operation switches for detecting the operation information, for example, in the case of the electric pot 1A, there are a boiling switch, a hot water supply switch, a heat insulation switch and the like. In the case of the rice cooker 1B, a rice cooker switch, a heat retention switch, a reservation switch, and the like can be given. Examples of the load components for detecting the operation information include light-emitting diodes that are turned on and blinking by operating the operation switch to turn them on, and load components such as an operating motor and a heater.

As shown in FIG. 3, the information signal of each of the electric appliances 1 is represented by 6 bits in a binary system. Among them, b6 indicates elapsed time information, and indicates 1 for periodic information every two hours and 0 for other operation information. b5
b3 indicates product information, and indicates 1 if applicable, and 0 if not applicable, depending on whether it corresponds to an electric pot, a rice cooker, or other. b2 indicates operation information, 1 when the load component is operating, and 0 when the load component is not operating.
Indicated by b1 indicates operation information, and indicates 1 when the operation switch is operated and 0 when the operation switch is not operated. For example,
When the hot water supply switch of the electric pot 1A is operated,
The operation information “000101” is sent to the central management unit 2. In addition, the information signal is, for example, amplification of transmission information.
Various modifications are possible.

The modulation / demodulation circuit 10 frequency-modulates the signal wave of the information signal input from the microcomputer 9 into a predetermined high-frequency current, and transmits the modulated wave to the domestic power line 4 via the transformer 11. Further, a modulated wave superimposed on the domestic power line 4 and conveyed is received via the transformer 11, demodulated into a predetermined signal wave, and output to the microcomputer 9.

As shown in FIG. 2, the centralized management unit 2

The microcomputer 14 of the present embodiment uses the built-in clock to control the electric product information recording unit 17 at predetermined time intervals.
Is analyzed to detect the presence / absence of operation information of the electric appliance 1 based on whether or not there is information in which 1 has been input to b1 of the information signal, and a transmission form to the monitor unit 3 based on the detection result. Set. Thereafter, the telephone line 5 is connected to the modem 18 via the switch 18a, and the telephone number of the monitor unit 3 registered in advance in the transmission information registration unit 16 in accordance with the set transmission mode is dialed. . The time at which the information is transmitted depends on the microcomputer 9 of the electrical product 1.
Similarly to the above, the time can be set at desired times such as every 6 hours, such as 6:00, 12:00, 18:00, and 24:00, or a plurality of set times.

In this embodiment, the monitor 3
As a form of transmission, when it is determined that there is no operation information in the detection of the operation information, if the number of call signals to the monitor unit 3 is transmitted once from the exchange side of the telephone line 5 after dialing, Try to close the line. on the other hand,
If it is determined that there is operation information, and the telephone line 5 is connected after dialing, the information recorded in the electrical product information recording unit 17 is transmitted. Here, the number of ringing signals means the number of wavelengths of waves in the ringing signal. One wavelength of the paging signal is detected by a time corresponding to a predetermined cycle or a wavelength in a wave of a response signal returned from the exchange.

The modulation / demodulation circuit 15 receives, via the transformer 20, a modulated wave from each of the electric appliances 1 superimposed on the domestic power line 4 and conveyed, similarly to the modulation / demodulation circuit 10 of the electric appliance 1. Then, the signal is demodulated into a predetermined signal wave and output to the microcomputer 14, and a return signal from the microcomputer 14 is modulated into a predetermined modulation wave.
0 and is superimposed on the domestic power line 4 and transmitted to the electric product 1.

The monitor section 3 is for centrally managing the operation information and operation information of the electric appliance 1 transmitted from each home to be monitored and for monitoring each home. As shown in FIG. Unit 22, number receiving unit 24, monitored home storage memory 25, information storage memory 26, microcomputer 2
As shown in FIG. 1, the telephone line 5 and a normal telephone 23 are branched and connected by the branch connection unit 22. A personal computer is applicable as the monitor unit 3. In this embodiment, a known caller notification system on the exchange side of the telephone line 5 is used.

The number receiving section 24 is a modem, which receives a caller telephone number notified from the exchange when a signal arrives, and outputs the number to the microcomputer 27.

The monitored home storage memory 25 stores names and telephone numbers of a plurality of monitored homes.
It is to be noted that the well-known telephone number registration method in the telephone 23 can be applied to this telephone number storing operation.

The information storage memory 26 is for individually recording information received from each of the monitored homes.

The microcomputer 27 stores the caller telephone number input from the number receiver 24 in the monitored home storage memory 25.
Is identified as matching with any one of the plurality of telephone numbers stored in. When the telephone number matches one of them and the number of call signals transmitted from the exchange side of the telephone line 5 is detected twice or more, the number receiving section 24
The telephone line 5 is automatically connected via a telephone, and the information of each home is received and stored in the information storage memory 26. If the number of the second call signal is not detected, the operation is performed in the home whose telephone number matches. It is determined that there is no information, and the result of the determination is stored in the information storage memory 26. If none of them match, the telephone line 5 is not automatically connected, so that the telephone 23 that has arrived at the same time as the monitor unit 3 via the branch connection unit 22 emits a ringing tone as usual. Since the comparison of the telephone numbers by the microcomputer 27 is performed in a short time, if the telephone numbers match and the connection is automatically established, the ringing tone of the telephone 23 is not transmitted.

Next, the operation of the microcomputer 9 of the electric appliance 1 in the life monitoring system will be described. For example, as shown in FIG. 5, the microcomputer 9 of the electric pot 1A first detects whether or not an operation switch such as the hot water supply switch has been operated in step S1, and if the operation has been detected, proceeds to step S2. The process proceeds to step S8 if not detected.

In step S2, 1 is set in the operation information b1.
And then, in step S3, other information b6-b
2 is set, and the process proceeds to step S4.

In step S4, the operation information set in step S3 is transmitted to the central management unit 2 via the domestic power line 4. The operation of the microcomputer 14 of the central management unit 2 will be described later in detail.

Next, in step S5, the timer is operated, and the flow advances to step S6. In this step S6, it is detected whether or not there is a reply from the central management unit 2 indicating that the transmitted information signal has been received, and if detected, the process returns. On the other hand, if no reply is detected, the process proceeds to step S7.

In step S7, it is detected whether or not the timer has expired. If the timer has counted up, the process returns to step S4 to retransmit the information signal to the central management unit 2. If the count has not been counted up, the process waits in step S6. The number of retransmissions can be set to a desired number.

If the operation of the operation switch is not detected in step S1, it is detected in step S8 whether or not the time for transmitting the operation information to the central management unit 2 has been reached. If the time has reached, the process proceeds to step S9, and if not, the process returns to step S1.

In step S9, 1 is set in the elapsed time information b6.
, And the process proceeds to step S10. This step S10
Then, for example, by detecting whether or not a load component such as a heater is operating, it is detected whether or not the electric appliance 1 is operating. If it is operating, the process proceeds to step S11, and the operation information b2 Is input to step S13, and the process proceeds to step S13. On the other hand, if no operation has been detected, step S1
In step S13, 0 is input to the operation information b2.
Proceed to.

In step S13, other information b5 to b
3, b1 is set, the process proceeds to step S4, and steps S4 to S7 are performed in the same manner as described above.

Next, the operation of the microcomputer 14 of the central management unit 2 will be described. The microcomputer 1 of the central management unit 2
4, first, as shown in FIG. 6, in step S20, it is detected whether an information signal has been received from the electric appliance 1,
If detected, the process proceeds to step S21. If not detected, the process proceeds to step S24.

In step S21, the received information signal is analyzed to determine what kind of information is transmitted from which electrical product 1, that is, which operation information or operation information is transmitted from which electrical product 1. After the information is recorded in the electric product information recording unit 17 in step S22, a reply signal to the electric product 1 is transmitted in step S23, and the process returns.

In step S24, it is determined by a built-in timer whether or not the time for transmitting information to the monitor 3 has come. If it is determined that the predetermined time has passed, the process proceeds to step S25, After performing the information transmission process, the process returns. On the other hand, if it is determined that the transmission time has not come, the process returns to step S20.

The information transmission process is as shown in FIG.
First, in step S25-1, the electrical product information recording unit 17
It is detected whether or not the operation information of the electric appliance 1 is included in the information recorded in the information signal based on whether b1 in the information signal is 1 or 0. S
The process proceeds to 25-2, and if there is no operation information, the process proceeds to step S25-7.

In step S25-2, all information recorded in the electrical product information recording unit 17 is set as an information signal to be transmitted, and in step S25-3, the monitor unit registered in the transmission information registration unit 16 is set. 3. Read the telephone number 3 and dial that number.

Then, in step S25-4, the process waits until the telephone line 5 is connected.
In step 25-5, the set information signal is transmitted. When the transmission of all information signals is completed, in step S25-6, the telephone line 5 is closed, and the process returns.

On the other hand, if there is no operation information in step S25-1, the telephone number of the monitor unit 3 registered in the transmission information registration unit 16 is read in step S25-7, and the number is dialed. I do.

Thereafter, at step S25-8, when it is detected that the number of call signals from the exchange side of the telephone line 5 to the monitor unit 3 is transmitted once (one wavelength), step S2-8 is performed.
Proceed to 5-6, close telephone line 5, and return.

Next, the operation of the monitor section 3 will be described. As shown in FIG. 8, the monitor unit 3 first controls the central management unit 2 via the telephone line 5 in step S30.
Or wait until a normal telephone signal arrives.

Next, when a signal is received in step S31, the telephone number of the caller notified from the exchange side of the telephone line 5 at the time of the incoming call is received via the number receiving unit 24.

Then, in step S32, the received number is compared with the number stored in the monitored home storage memory 25. If there is a matched number, the process proceeds to step S33, in which all numbers are not matched. In this case, the process skips steps S33 to S38 to be described later and returns without performing automatic connection.

In step S33, it is detected whether or not the number of wavelengths of the calling signal transmitted from the exchange side of the telephone line 5 is two or more. On the other hand, if the wavelength of the second call signal is not detected, that is, if the wavelength of the call signal is only one, the process proceeds to step S38.

In step S34, the telephone line 5 is automatically connected via the number receiving unit 24 which is a modem.
At step 35, the information signal that is subsequently input is received and analyzed, and when the analysis of all the information is completed, the process proceeds to step S36.
Then, the information is recorded in the information storage memory 26 corresponding to the monitored home determined by the comparison in step S32. Also, in step S37, the name of the monitored home determined by comparison in step S32 and the name in step S35 are compared.
The information analyzed in step is output to the monitor 28 and displayed,
To return.

On the other hand, if the wavelength of the calling signal is only one in step S33, it is determined in step S38 that there is no operation information of the electric appliance in the monitored home. Then, in the same manner as described above, in step S36, the result of the determination is recorded in the information storage memory 26 corresponding to the monitored home, and in step S37, the name of the monitored home determined by comparison in step S32 and the name in step S38 Is output to the monitor 28 for display.

Then, the monitoring person determines that something abnormal has occurred in the monitored home by viewing the determination result on the monitor 28, and makes a telephone call to the monitored home,
Confirmation of safety by direct visit.

In step S32, since the received telephone number does not match all the stored numbers,
When returning without automatic connection, the telephone 23 simultaneously receives a call via the branch connection unit 22, thereby transmitting a ringing sound as usual and notifying the observer that a normal telephone signal has been received.

Further, if none of the above-mentioned displays is output to the monitor 28 even when the operation status of the home to be monitored is periodically transmitted, the person to be monitored is:
It is determined that an abnormality has occurred in the monitor unit 3 for some reason such as a power failure, and the abnormality is resolved by making a telephone call or directly visiting the monitored home.

As described above, in the life monitoring system according to the first embodiment, the operation state and operation state of the electric appliances necessary for estimating the actual living state in the monitored home are reliably transmitted to the monitor unit 3. However, even if there is no operation information, the information is transmitted to the monitor unit 3. Therefore, if there is no regular transmission, the central management unit 2 can determine that transmission is not possible for some reason. That is, since it is easy to estimate and judge the living situation in the home, it is possible to improve the convenience of the person who monitors.

FIGS. 9 and 10 show a life monitoring system according to a second embodiment. In the second embodiment, the periodical transmission time (transmission time of a call signal) to the monitor unit 3 is changed based on the result detected by the central management unit 2, and only the detection result is transmitted to the monitor unit 3. I try to send. In the first embodiment, the abnormality of the central management unit 2 can be detected. However, in the second embodiment, the abnormality of the electric appliance 1 can be detected in addition to the abnormality of the central management unit 2. This is different from the first embodiment in the point.

That is, the microcomputer 14 of the central management unit 2 according to the second embodiment sets the reference time of the periodic transmission to the monitor unit 3 to T.
When it is determined that there is no operation information by the detection of the operation information, the electronic product information recording unit 17 determines that there is no operation information and no operation information. One minute later, if it is determined that “there is operation information”, the dial is dialed to the monitor unit 2 two minutes after the scheduled time T.
The transmission time is delayed by a built-in timer.

As in the first embodiment, the microcomputer 27 of the monitor unit 3 determines whether the caller telephone number input from the number receiving unit 24 is one of a plurality of telephone numbers stored in the monitored home storage memory 25. After identifying whether or not it matches, the time is read by a built-in clock. In the present embodiment, the monitored home storage memory 25 includes:
The time T at which the caller performs regular transmission is stored together with the caller's telephone number, and the transmission information from the centralized management unit 2 is determined based on an error from the time T, and the determination result is stored in an information storage memory. 26.

Next, the operation of the microcomputer 14 of the central management unit 2 according to the second embodiment will be described. The operation of the microcomputer 14 differs from that of the first embodiment only in the information transmission process of step S25 shown in FIG. More specifically, as shown in FIG. 9, this information transmission process first includes step S25'-
In step 1, it is detected whether or not the operation information and the operation information of the electric appliance 1 are recorded in the electric appliance information recording unit 17, and if there is any information, the process proceeds to step S25'-2. If there is no information of step S2, step S2
Proceed to 5'-5.

In step S25'-2, it is determined whether or not the detected information includes the operation information of the electric appliance 1 based on whether b1 in the information signal is 1 or 0. If it is determined that there is information, step S2
Proceed to 5'-3, set the delay timer to 2 minutes, and proceed to step S25'-6.

If it is determined in step S25'-2 that there is no operation information, step S25'-4.
To set the delay timer to 0 minutes, and then to step S25 '
Go to -6.

On the other hand, if it is determined in step S25'-1 that there is no operation information or motion information, step S25'-1 is executed.
In step 25'-5, the delay timer is set to one minute, and the flow advances to step S25'-6.

In step S25'-6, the process waits until the delay timer counts up. When the count is counted up, in step S25'-7, the telephone number of the monitor unit 3 registered in the transmission information registration unit 16 is read. After dialing the number, in step S25'-8, the telephone line 5 is closed and the routine returns.

Next, the operation of the monitor section 3 of the second embodiment will be described. As shown in FIG. 10, the monitor unit 3 first waits at step S40 until a signal of the central management unit 2 or a normal telephone is received via the telephone line 5.

Next, when a signal is received in step S41, the telephone number of the caller notified from the exchange side of the telephone line 5 at the time of the incoming call is received via the number receiving unit 24.

Then, in step S42, the received number is compared with the number stored in the monitored home storage memory 25. If there is a matched number, the process proceeds to step S43, where all numbers are not matched. In this case, the process returns from step S43 to step S49 to be described later.

In step S43, it is detected whether or not the arrival time is less than the time obtained by adding one minute to the time T, and the time T +
When it is determined that the operation time is less than one minute, the process proceeds to step S44, and it is determined that “there is no operation information”, that is, it is determined that the operation information of the electric appliance 1 is not recorded in the central management unit 2 of the monitored home. The process proceeds to step S48.

On the other hand, at step S43, the time T + 1
If it is determined that the time is equal to or longer than minutes, the process proceeds to step S45,
Further, it is detected whether or not the incoming time is less than the time obtained by adding the error 2 minutes to the on-time T, and if it is determined that the incoming time is less than the on-time T + 2 minutes, the process proceeds to step S46, and it is determined that “there is no transmission information”.
That is, it is determined that neither the operation information nor the operation information of the electric appliance 1 is recorded in the central management unit 2 of the monitored home, and the process proceeds to step S48.

In step S45, the time T + 2
If it is determined that the time is equal to or longer than minutes, the process proceeds to step S47,
It is determined that "there is operation information", that is, it is determined that the operation information of the electric appliance 1 is recorded in the centralized management unit 2 of the monitored home, and the process proceeds to step S48.

In step S48, step S4
The results of the determinations at steps S42, S46 and S47 are
After recording in the information storage memory 26 corresponding to the monitored home determined by the comparison in step S49, the name of the determined monitored home and the determination result are output to the monitor 28 in step S49.
To return.

When the person who watches the monitor 28 of the monitor unit 3 receives the call within 1 minute from the scheduled time T and sees the determination that there is no operation information, the household appliance to be monitored operates the electric appliance 1. If not, call or visit the home to deal with it. In addition, from time T
When it is determined that there is no transmission information due to an incoming call in less than a minute, it is determined that there is no information to be transmitted due to, for example, the power of the electric appliance 1 being turned off. The power supply of the product 1 is connected to an outlet, or if the electric product 1 is out of order, it is replaced. Furthermore, when it is determined that “operation information is present” by receiving an incoming call within three minutes from the scheduled time T, it is determined that there is no problem in the home to be monitored.

As described above, in the life monitoring system of the second embodiment, by changing the transmission time of the call signal to the monitor unit 3, the minimum necessary information can be monitored in the same manner as in the first embodiment. 3 can be sent quickly.

The life monitor system of the present invention
It is not limited to the above embodiment. For example, in the first embodiment, when the central management unit 2 determines that “operation information is present”, all information recorded in the electric appliance information recording unit 17 is transmitted. When it is determined, the number of call signals to the monitor unit 3 is once, when it is determined that there is no transmission information, the number of call signals is three, when it is determined that there is operation information, the number of call signals is five, and the number of call signals is five. Necessary information may be determined by the monitor unit 3 only by the number of items.

In this case, the telephone 23 that receives a call at the same time
Since the number of ringing tones corresponding to the number of ringing signals is emitted, there is a possibility that the receiver is erroneously picked up. Therefore, in the case of the above configuration, the central management unit 2 on the caller side sets the number of call signals to be transmitted in one access (transmission operation) as, for example, only once (one wavelength) and once the telephone line. Close 5,
While a configuration is made in which access is performed a required number of times within a predetermined time such as one minute, the monitor unit 3 on the receiver side determines how many times the number of call signals has been received from a specific sender within a predetermined time. It is preferable to accumulate and make a judgment based on the accumulated number. It should be noted that the number of call signals and transmission information corresponding to the number can be variously changed as desired.

In the second embodiment, when it is determined that “operation information is present”, all information recorded in the electrical product information recording unit 17 is transmitted similarly to the first embodiment. Is also good. Alternatively, the central control unit 2 is equipped with the same number receiving unit and storage memory as the monitor unit 3,
When an incoming call from the monitor unit 3 is detected, the telephone line 5 is automatically connected, and all information recorded in the electrical product information recording unit 17 can be transmitted.

Further, in the first embodiment, the number of call signals to the monitor unit 3 is changed, and in the second embodiment, the transmission time of the call signal to the monitor unit 3 is changed. More detailed situations can be transmitted to and received from the monitor unit 3 quickly.

[0073]

As is clear from the above description, in the life monitoring system of the present invention, the central management means sets the transmission form to the monitor means based on the detection result by the detection means, In the above, the number receiving means and the storage means identify the incoming call from the specific caller by the telephone number notified at the time of the incoming call from the exchange side of the telephone line, and monitor the incoming call from the central management means by the incoming call form from the central management means. Since the situation is determined, information can be transmitted and received accurately according to the living situation of the monitored home.

More specifically, if the number of call signals to the monitor means is changed or the time at which the call signal is sent to the monitor means is changed as the transmission form, the monitor means Since the information to be transmitted can be determined based on the incoming call form from the centralized management means, necessary information can be transmitted and received quickly.
