Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a life monitoring system that can monitor the safety of elderly people who are living alone or physically disabled persons over a long distance.
[0002]
[Prior art]
  Conventionally, this type of life monitoring system uses information on operation of a predetermined electric appliance in the home, for example, on / off operation of a hot water supply switch of an electric kettle, using a dedicated signal carrying path or a domestic power line. Then, the information is transmitted to the centralized management means arranged in the home, and the operation information and the like are recorded and managed by the centralized management means. Then, when the information recorded in the centralized management means reaches a predetermined time, the destination data (telephone number) registered in advance in the centralized management means is dialed and information such as a code for identifying the user is telephoned. The information is sent to a monitor such as a personal computer installed in a clinic outside the home via a line, so that the safety of elderly people who are living alone or disabled persons can be monitored according to the usage status of electrical products. However, when information is transmitted from the centralized management unit to the monitoring unit, if there is no operation information of the electric product, the transmission is not performed.
[0003]
[Problems to be solved by the invention]
  However, in the life monitoring system, there is no periodic transmission on the monitor means side outside the home because there is no operation information of the electrical product, or there is no periodic transmission because the electrical product or the centralized management means has failed for some reason. I can't judge.
[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 quickly determine the situation in the home to be monitored.
[0005]
[Means for Solving the Problems]
  In order to solve the above-described problems, the life monitoring system of the present invention records and manages information on electrical appliances arranged in the home by centralized management means, and the information is transmitted to the monitoring means outside the home via a telephone line at a predetermined time. In the life monitoring system for monitoring the living situation by transmitting, the central management means is provided with the information recording means of the electric product, and the information in the electric product information recording means is detected when information is transmitted to the monitoring means Detecting means for setting the transmission form to the monitoring means based on the detection result of the detecting means.SendThe monitoring means is provided with a number receiving means for receiving a caller telephone number notified from the exchange side of the telephone line when an incoming call is received, and a storage means for storing a telephone number of a specific caller is provided, and the number receiving means A specific caller is identified by comparing the received telephone number with the telephone number stored in the storage means, and the situation of the home to be monitored is determined by the incoming call form from the centralized management means.The transmission form from the centralized management means is set as the calling signal transmission time to the monitoring means, and the periodic transmission time is changed based on the detection result of the detection means.It is configured.
[0006]
  According to the life monitoring system, on the central management means side, the transmission mode to the monitoring means is set based on the detection result by the detection means, while on the monitoring means side, the telephone line switch is provided by the number receiving means and the storage means. Since the incoming call from a specific caller is identified by the telephone number notified at the time of incoming call from the side, and the situation of the home to be monitored is determined by the incoming call form from the centralized management means, the life of the home to be monitored Information can be transmitted and received accurately according to the situation.In addition, since the transmission form from the centralized management means is the call signal transmission time to the monitoring means, the necessary information to be transmitted to the monitoring means can be quickly obtained simply by accessing the monitoring means via a telephone line. You can send and receive.
[0007]
  In the life monitoring system, the transmission form from the centralized management meansAsThe number of call signals to the monitoring meansFurther changeIs preferable.
Here, the number of calling signals means the number of wavelengths in the wave of the calling signal. Further, this number means the number of wavelengths transmitted by one transmission operation from the sender side or the cumulative number of wavelengths transmitted within a predetermined time.
  In this case, the monitor means automatically connects the telephone line 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 more than a predetermined number is detected. It is preferable.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
  FIG. 1 illustrates the present invention.Reference examplesShows the life monitor system. This life monitoring system includes an electrical product 1 and a central management unit 2 installed in a home to be monitored, and a monitor unit 3 installed in a clinic outside the home.This reference exampleThen, as a means for connecting the electrical product 1 and the centralized management unit 2, the domestic power line 4 is used as a signal transport path, and as a means for connecting the centralized management unit 2 and the monitor unit 3, an exchange not shown is used. A wired telephone line 5 which is a normal public telephone line connected is used.
[0009]
  As shown in FIG. 2, the electrical product 1 includes a microcomputer 9 and a modulation / demodulation circuit 10 that also serve as an operation status detection unit, in addition to a normal electrical product including a load control circuit 7 and a display panel unit 8. It is a thing. In addition,This reference exampleThen, although the electric pot 1A and the rice cooker 1B are illustrated as the electric product 1, it cannot be overemphasized that it is applicable to all the electric products 1 used in homes, such as an air cleaner, an air-conditioner, and a vacuum cleaner. Yes.
[0010]
  The microcomputer 9 detects the operation information of the operation switch disposed on the display panel unit 8 and the operation of the electrical product 1 at a desired time such as every two hours by a built-in clock. Information is transmitted to the modulation / demodulation circuit 10 as a predetermined signal wave. Further, it is detected whether or not a reply is sent from the centralized management unit 2 to the modulation / demodulation circuit 10, and when a reply is not detected within a predetermined time by a built-in timer, a signal wave is retransmitted.
[0011]
  Here, as the operation switch 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 retention switch, and the like. In the case of the rice cooker 1B, a rice cooking switch, a heat retention switch, a reservation switch, etc. are mentioned. Examples of load components for detecting operation information include light-emitting diodes that are turned on and blinking by operating the operation switch to turn on, and load components such as an operating motor and a heater.
[0012]
  As shown in FIG. 3, the information signal of each electrical product 1 is expressed in binary, 6 bits. Of these, b6 indicates elapsed time information, and 1 indicates periodic information every 2 hours, and 0 indicates other operation information. b5 to b3 indicate product information, and 1 indicates a case corresponding to the electric pot, rice cooker, or other, and 0 indicates a case where it does not correspond. b2 indicates operation information, and 1 indicates that the load component is operating, and 0 indicates that it is not operating. b1 indicates operation information, which is 1 when the operation switch is operated and 0 when it is not operated. For example, when the hot water supply switch of the electric pot 1A is operated, operation information “000101” is sent to the centralized management unit 2. The information signal can be variously modified such as amplification of transmission information.
[0013]
  The modulation / demodulation circuit 10 frequency-modulates the signal wave of the information signal input from the microcomputer 9 to a predetermined high-frequency current, and transmits the modulated wave to the domestic power line 4 via the transformer 11. In addition, a modulated wave conveyed while being superimposed on the domestic power line 4 is received via the transformer 11, demodulated into a predetermined signal wave, and output to the microcomputer 9.
[0014]
  As shown in FIG. 2, the central management unit 2 includes a microcomputer 14, a modulation / demodulation circuit 15, a transmission information registration unit 16, an electrical product information recording unit 17, a modem 18, the central management unit 2 side, and a telephone. And a switching device 18a for switching the connection to the 21 side.
[0015]
  The microcomputer 14 analyzes the information signal of each electrical product 1 received via the modulation / demodulation circuit 15 and determines which electrical product 1 has been operated in ○ hour × minute or which electrical product 1 in ○ hour × minute. Is recorded in the electrical product information recording unit 17.
[0016]
  This reference exampleThe microcomputer 14 analyzes the recorded information of the electrical product information recording unit 17 at predetermined time intervals using a built-in clock, and determines whether there is information in which 1 is input in b1 of the information signal. Is detected, and the transmission mode to the monitor unit 3 is set based on the detection result. 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 is dialed according to the set transmission mode. . The time for transmitting the information is the same as the microcomputer 9 of the electrical product 1, such as every 6 hours such as 6 o'clock, 12 o'clock, 18 o'clock and 24 o'clock, or a plurality of set times. Can be set to
[0017]
  Also,This reference exampleThen, as a transmission form to the monitor unit 3, when it is determined that there is no operation information by detecting the operation information, the number of calling signals from the exchange side of the telephone line 5 to the monitor unit 3 after dialing The line is closed once is sent. On the other hand, when it is determined that there is operation information, when the telephone line 5 is connected after dialing, the information recorded in the electrical product information recording unit 17 is subsequently transmitted.
  Here, the number of ringing signals means the number of wave wavelengths in the ringing signal. One wavelength of the calling signal is detected by a time corresponding to a predetermined period or a wavelength in a wave of a response signal returned from the exchange side.
[0018]
  Similar to the modulation / demodulation circuit 10 of the electrical product 1, the modulation / demodulation circuit 15 receives a modulated wave from each electrical product 1 superimposed and carried on the domestic power line 4 via the transformer 20, The signal is demodulated and output to the microcomputer 14, the return signal from the microcomputer 14 is modulated into a predetermined modulated wave, and the modulated wave is superimposed on the domestic power line 4 via the transformer 20. This is transmitted to the electrical product 1.
[0019]
  The monitor unit 3 is for centrally managing the operation information and operation information of the electrical product 1 transmitted from each home to be monitored and monitoring each home. As shown in FIG. , A number receiving unit 24, a monitoring home storage memory 25, an information storage memory 26, and a microcomputer 27. As shown in FIG. 1, the telephone line 5 and a normal telephone set 23 are connected by the branch connection unit 22. Branch connection. A personal computer is applicable as the monitor unit 3. In addition,This reference exampleThen, a known caller notification system on the exchange side of the telephone line 5 is used.
[0020]
  The number receiving unit 24 is a modem, which receives a caller telephone number notified from the exchange side when a signal is received, and outputs the number to the microcomputer 27.
[0021]
  The monitoring home storage memory 25 stores names and telephone numbers in a plurality of monitoring homes. Note that the telephone number registration method in the well-known telephone 23 can be applied to the telephone number storing operation.
[0022]
  The information storage memory 26 individually records information received from each monitoring home.
[0023]
  The microcomputer 27 identifies whether or not the caller telephone number input from the number receiving unit 24 matches any one of a plurality of telephone numbers stored in the monitored home storage memory 25. When the telephone number matches any one and the number of call signals sent from the exchange side of the telephone line 5 is detected twice or more, the telephone line 5 is automatically connected via the number receiving unit 24, and When the information is received and stored in the information storage memory 26 while the number of second call signals is not detected, it is determined that there is no operation information in the home whose telephone number matches, and the determination result is stored in the information storage memory. 26. If they do not coincide with each other, the telephone line 5 is not automatically connected, so that the telephone 23 that has received the call at the same time as the monitor unit 3 via the branch connection unit 22 transmits a ringing tone as usual. Since the comparison of the telephone numbers by the microcomputer 27 is processed in a short time, the ringing sound of the telephone set 23 is not transmitted when the telephone numbers match and are automatically connected.
[0024]
  Next, the operation of the microcomputer 9 of the electric product 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 is operated in step S1, and if the operation is detected, step S2 If not detected, the process proceeds to step S8.
[0025]
  In step S2, 1 is input to the operation information b1, and then in step S3, other information b6 to b2 is set, and the process proceeds to step S4.
[0026]
  In step S4, the operation information set in step S3 is transmitted to the centralized management unit 2 via the domestic power line 4. The operation of the microcomputer 14 of the central management unit 2 will be described in detail later.
[0027]
  Next, in step S5, the timer is operated, and the process proceeds to step S6. In this step S6, it is detected whether or not there has been a reply from the centralized management unit 2 indicating that the transmitted information signal has been received. On the other hand, if no reply is detected, the process proceeds to step S7.
[0028]
  In step S7, it is detected whether or not the timer has timed up. If the timer has been counted up, the process returns to step S4 to retransmit the information signal to the centralized management unit 2. If the count is not up, the process waits in step S6. Note that the number of retransmissions can be set to a desired number.
[0029]
  If no operation switch operation is detected in step S1, it is detected in step S8 whether or not it is time to transmit operation information to the centralized management unit 2, and the predetermined time has elapsed. If this is the case, the process proceeds to step S9.
[0030]
  In step S9, 1 is input to the elapsed time information b6, and the process proceeds to step S10. In this step S10, for example, it is detected whether or not the electrical product 1 is operating by detecting whether or not a load component such as a heater is operating. If it is operating, the process proceeds to step S11. Enter 1 in the operation information b2, and proceed to Step S13. On the other hand, if no operation is detected, the process proceeds to step S12, 0 is input to the operation information b2, and the process proceeds to step S13.
[0031]
  In step S13, other information b5 to b3 and b1 are set, the process proceeds to step S4, and steps S4 to S7 are performed in the same manner as described above.
[0032]
  Next, the operation of the microcomputer 14 of the centralized management unit 2 will be described.
  First, as shown in FIG. 6, the microcomputer 14 of the centralized management unit 2 detects whether or not an information signal is received from the electrical product 1 in step S20, and if detected, proceeds to step S21. If not detected, the process proceeds to step S24.
[0033]
  In step S21, the received information signal is analyzed, and what information is transmitted from which electrical product 1, that is, from which electrical product 1, which operation information or operation information is transmitted. After the information is recorded in the electrical product information recording unit 17 in step S22, a reply signal for the electrical product 1 is transmitted in step S23, and the process returns.
[0034]
  In step S24, it is determined whether it is time to transmit information to the monitor unit 3 by the built-in timer. If it is determined that the predetermined time has been reached, the process proceeds to step S25, and information transmission processing to the monitor unit 3 is performed. Return after performing.
  On the other hand, if it is determined that it is not the transmission time, the process returns to step S20.
[0035]
  As shown in FIG. 7, in the information transmission process, first, in step S25-1, whether or not there is operation information of the electrical product 1 in the information recorded in the electrical product information recording unit 17 is determined as information. If it is detected whether b1 in the signal is 1 or 0 and there is operation information, the process proceeds to step S25-2. If there is no operation information, the process proceeds to step S25-7.
[0036]
  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 then the telephone of the monitor unit 3 registered in the transmission information registration unit 16 in step S25-3. Read a number and dial the number.
[0037]
  In step S25-4, the process waits until the telephone line 5 is connected. When the telephone line 5 is connected, in step S25-5, the set information signal is transmitted. When transmission of all the information signals is completed, step S25 is performed. At -6, the telephone line 5 is closed and then the process returns.
[0038]
  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 and dialed in step S25-7.
[0039]
  Thereafter, in step S25-8, when it is detected that the number of calling signals from the exchange side of the telephone line 5 to the monitor unit 3 is transmitted once (one wavelength), the process proceeds to step S25-6 and the telephone line 5 is connected. Return after closing.
[0040]
  Next, the operation of the monitor unit 3 will be described.
  As shown in FIG. 8, the monitor unit 3 first waits until the centralized management unit 2 or a normal telephone signal is received via the telephone line 5 in step S30.
[0041]
  In step S31, when a signal is received, the telephone number of the caller notified from the exchange side of the telephone line 5 is received via the number receiving unit 24 when the call is received.
[0042]
  In step S32, the received number is compared with the number stored in the monitored home storage memory 25. If there is a matching number, the process proceeds to step S33. If all the numbers do not match, Then, step S33 to step S38 described later are skipped, and the process returns without performing automatic connection.
[0043]
  In step S33, it is detected whether or not the number of wavelengths of the paging signal transmitted from the exchange side of the telephone line 5 is two times or more. When the wavelength of the paging signal is detected twice or more, the process proceeds to step S34. When the wavelength of the second call signal is not detected, that is, when the wavelength of the call signal is only once, the process proceeds to step S38.
[0044]
  In step S34, the telephone line 5 is automatically connected via the number receiving unit 24, which is a modem. In step S35, subsequently received information signals are received and analyzed, and when analysis of all information is completed, In step S36, the information is recorded in the information storage memory 26 corresponding to the monitored household determined by the comparison in step S32. In step S37, the name in the monitoring home determined in comparison in step S32 and the information analyzed in step S35 are output and displayed on the monitor 28, and the process returns.
[0045]
  On the other hand, if the wavelength of the calling signal is only once in step S33, it is determined in step S38 that there is no operation information on the electrical product in the home to be monitored. In the same manner as described above, in step S36, the determination result is recorded in the information storage memory 26 corresponding to the monitored home. In step S37, the name in the monitored home determined by comparison in step S32 and the step S38 are recorded. The information determined in (1) is output to the monitor 28 and displayed.
[0046]
  Then, the monitoring person views the determination result on the monitor 28 to determine that something abnormal has occurred in the monitored household, and confirms the safety by calling or directly visiting the monitored household. I do.
[0047]
  In step S32, since the received telephone number does not match all the stored numbers, when the telephone 23 returns simultaneously without automatic connection, the telephone 23 receives the call via the branch connection unit 22 at the same time. A ringing tone is emitted to inform the supervisor that a normal telephone signal has been received.
[0048]
  Furthermore, if any of the above-described displays are not output to the monitor 28 even when the operation status of the home to be monitored is a periodical transmission time, the person who is monitoring is in a certain state such as a power failure. For this reason, it is determined that an abnormality has occurred in the monitor unit 3, and the abnormality is resolved by making a telephone call or directly visiting the home to be monitored.
[0049]
  in this way,Reference exampleIn this life monitoring system, the operation status and operation status of the electrical product necessary for estimating the actual living status in the home to be monitored are reliably transmitted to the monitor unit 3, and even if there is no operation information, the information is stored. Since the data is transmitted to the monitor unit 3, if there is no regular transmission, the centralized management unit 2 can determine that transmission cannot be performed for some reason. That is, since it becomes easy to estimate and judge the living situation in the home, it is possible to improve the convenience of the person who monitors.
[0050]
  9 and 10 areAccording to the embodiment of the present inventionThe life monitor system is shown.This embodimentThen, based on the result detected by the centralized management unit 2, the periodic transmission time (call signal transmission time) to the monitor unit 3 is changed, and only the detection result is transmitted to the monitor unit 3. Yes. Also,Reference exampleNow, it is possible to detect abnormalities in the centralized management unit 2,This embodimentThen, in addition to the abnormality of the centralized management unit 2, the abnormality of the electrical product 1 can be detected.It is different.
[0051]
  That is,This embodimentThe microcomputer 14 of the centralized management unit 2 sets the reference time for periodic transmission to the monitor unit 3 to T, and when it is determined that “no operation information” is detected by the detection of the operation information, When it is determined that “there is no operation information and no operation information for the electrical product 1”, the monitor unit 3 is dialed one minute after the scheduled time T, and when it is determined that “there is operation information”, the monitor unit 3 is dialed two minutes after the scheduled time T. The transmission time is delayed by a built-in timer.
[0052]
  The microcomputer 27 of the monitor unit 3Reference exampleIn the same manner as described above, after identifying whether the caller telephone number input from the number receiving unit 24 matches any of the plurality of telephone numbers stored in the monitored home storage memory 25, the built-in clock The time is read with. Further, in the present embodiment, the monitoring home storage memory 25 stores a time T at which periodic transmission is performed from the caller together with the caller telephone number, and the centralized management unit 2 is based on an error from this time T. Transmission information is determined, and the determination result is stored in the information storage memory 26.
[0053]
  next,This embodimentThe operation of the microcomputer 14 of the central management unit 2 will be described.
  The operation of the microcomputer 14 is only the information transmission process of step S25 shown in FIG.Reference exampleIs different. Specifically, as shown in FIG. 9, in the information transmission process, first, in step S25′-1, whether or not operation information and operation information of the electrical product 1 are recorded in the electrical product information recording unit 17 is determined. If there is any information, the process proceeds to step S25′-2, and if there is no information, the process proceeds to step S25′-5.
[0054]
  In step S25′-2, whether the operation information of the electrical product 1 is included in the detected information is detected based on whether b1 in the information signal is 1 or 0, and there is operation information. If it is determined, the process proceeds to step S25′-3, the delay timer is set to 2 minutes, and the process proceeds to step S25′-6.
[0055]
  If it is determined in step S25'-2 that there is no operation information, the process proceeds to step S25'-4, the delay timer is set to 0 minutes, and the process proceeds to step S25'-6.
[0056]
  On the other hand, if it is determined in step S25'-1 that there is neither operation information nor operation information, in step S25'-5, the delay timer is set to 1 minute, and the process proceeds to step S25'-6.
[0057]
  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, and the number is read. After dialing, in step S25'-8, the telephone line 5 is closed and the process returns.
[0058]
  next,This embodimentThe operation of the monitor unit 3 will be described.
  As shown in FIG. 10, the monitor unit 3 first waits until an incoming signal of the centralized management unit 2 or a normal telephone is received via the telephone line 5 in step S40.
[0059]
  In step S41, when a signal is received, the telephone number of the caller notified from the exchange side of the telephone line 5 is received via the number receiving unit 24 when the call is received.
[0060]
  In step S42, the received number is compared with the number stored in the monitoring home storage memory 25. If there is a matching number, the process proceeds to step S43. If all the numbers do not match, Then, the process returns from step S43 to step S49 which will be described later.
[0061]
  In step S43, it is detected whether or not the incoming time is less than the time obtained by adding an error of 1 minute to the scheduled time T. If it is determined that the incoming time is less than the scheduled time T + 1 minutes, the process proceeds to step S44, where “no operation information” is determined. Then, it is determined that the operation information of the electric product 1 is not recorded in the centralized management unit 2 of the home to be monitored, and the process proceeds to step S48.
[0062]
  On the other hand, if it is determined in step S43 that the time is not less than the scheduled time T + 1 minutes, the process proceeds to step S45, and it is further detected whether the incoming time is less than the time obtained by adding the error 2 minutes to the scheduled time T, and less than the scheduled time T + 2 minutes. If it is determined, the process proceeds to step S46, where “no transmission information” is determined, that is, neither the operation information nor the operation information of the electrical product 1 is recorded in the centralized management unit 2 of the home to be monitored. Judge and proceed to step S48.
[0063]
  If it is determined in step S45 that the time is equal to or more than the scheduled time T + 2 minutes, the process proceeds to step S47, where “operation information is present” is determined. Is recorded, and the process proceeds to step S48.
[0064]
  In step S48, the determination results in steps S44, S46, and S47 are recorded in the information storage memory 26 corresponding to the monitored home determined in the comparison in step S42, and then in step S49, the name of the monitored home determined. The determination result is output to the monitor 28 and the process returns.
[0065]
  And if the person who watches the monitor 28 of the monitor unit 3 arrives within 1 minute from the scheduled time T and sees the judgment of “no operation information”, the electrical appliance 1 is not operated in the home to be monitored. Determine and deal with the home by phone or visit. In addition, when it is judged that there is no transmission information by receiving an incoming call in less than 2 minutes from the scheduled time T, it is determined that there is no information to be transmitted due to, for example, the power supply of the electrical product 1 being disconnected. Call or visit to connect the power source of the electrical product 1 to an outlet, or take measures such as replacing the electrical product 1 if it is broken. Further, when it is judged that there is “operation information” by receiving a call within 3 minutes from the scheduled time T, it is determined that there is no problem in the home to be monitored.
[0066]
  in this way,This embodimentIn the life monitor system of the above, by changing the call signal transmission time to the monitor unit 3,Reference exampleSimilarly to the above, the minimum necessary information can be quickly transmitted to the monitor unit 3.
[0067]
  The life monitoring system of the present invention is not limited to the above embodiment.
  For example, theReference exampleThen, when the central management unit 2 determines that “operation information is present”, all information recorded in the electrical product information recording unit 17 is transmitted. If the number of ringing signals is one time, “no transmission information” is determined, the number of ringing signals is three. If it is determined that “operation information is present”, the number of ringing signals is five. May be determined by the monitor unit 3.
[0068]
  In this case, since the telephones 23 that receive the call at the same time emit the ringing tone corresponding to the number of the ringing signals, there is a possibility of picking up the receiver by mistake. Therefore, in the case of the above configuration, in the centralized management unit 2 on the caller side, the number of call signals to be transmitted in one access (transmission operation) is, for example, only once (one wavelength), and the telephone line is temporarily set. 5 is closed and access is made as many times as necessary within a predetermined time such as 1 minute. On the other hand, the monitoring unit 3 on the receiver side sets the number of call signals from a specific caller within a predetermined time. It is preferable that a configuration is made so as to determine whether or not a call has arrived and to determine based on the cumulative number. The number of call signals and the transmission information corresponding to the number can be changed as desired.
[0069]
  Also,This embodimentThen, when it is determined that “operation information is present”,Reference exampleSimilarly, all the information recorded in the electrical product information recording unit 17 may be transmitted. Alternatively, the central management unit 2 is equipped with a number receiving unit and a storage memory similar to those of the monitor unit 3. When an incoming call from the monitor unit 3 is detected, the telephone line 5 is automatically connected to the electronic product information recording unit 17. It is also possible to transmit all the information recorded in.
[0070]
  In addition,Reference exampleThen, the number of call signals to the monitor unit 3,This embodimentIn this case, the call signal transmission time to the monitor unit 3 is changed. However, if these are combined, a more detailed situation can be quickly transmitted to and received from the monitor unit 3.
[0071]
