Hereinafter, the operation of the terminal device 24 will be described.
FIG. 4 is a diagram showing an example of a timing table in which notification timings of measurement values are determined. The timing table is a table in which the notification frequency of the measurement value is defined with respect to the usage period of the gas device 30, and is stored in advance in the storage unit 241 of the terminal device 24. Here, the usage period of the gas device 30 may be the net time (cumulative time) when the gas device 30 was actually used, or even the elapsed time since the gas device 30 was first used Good. In the example of the timing table shown in FIG. 4, when the usage period of the gas device 30 is 0 years or more and less than 6 years, the notification frequency is once a year and the usage period is 6 years or more and less than 10 years. If the notification frequency is once every six months and the usage period is 10 years or more, it is defined that the notification frequency is once a month.

  The control unit 240 of the terminal device 24 refers to the timing table stored in the storage unit 241, and sets the notification timing of the measurement value to the center side.

  In this embodiment, although the configuration for setting the notification timing of the measurement value by the timing table will be described, the control unit 240 sets the notification timing using a function having the use period as the input value and the notification timing as the output value. Of course, the configuration may be

  FIG. 5 is a flow chart for explaining the procedure of processing executed by the terminal device 24 according to the first embodiment. The control unit 240 of the terminal device 24 refers to the timing table stored in the storage unit 241 and sets the next notification timing (step S101). For example, when the current usage period of the gas device 30 is five years, the notification frequency is determined to be once a year in the timing table shown in FIG. The timing which added the period of 1 year to the last notice timing with reference to the information concerning the last notice timing memorized is set up as the next notice timing.

  Next, the control unit 240 determines whether the present corresponds to the notification timing (step S102). In the case where the net time (cumulative time) in which the gas device 30 is actually used is used as the use time of the gas device 30, the control unit 240 may, for example, input a measurement value indicating that the gas device 30 is operating It is possible to determine whether or not the present corresponds to the notification timing by clocking the time input from the unit 243 using the built-in counter as the net time when the gas device 30 is used. Moreover, when using the elapsed time after the gas apparatus 30 was first used as use time of the gas apparatus 30, whether the control part 240 corresponds now to notification timing based on the date information output from a built-in clock? Decide whether or not.

  When it is determined that the present does not correspond to the notification timing (S102: NO), the control unit 240 stands by until the notification timing.

  When it is determined that the present corresponds to the notification timing (S102: YES), the control unit 240 sends the latest measurement value input from the sensor input unit 243 to the wireless slave device 22 through the connection unit 242 (step S103). . In addition, the control unit 240 causes the storage unit 241 to store information related to the notified timing.

  When the wireless slave device 22 acquires the measured value from the sensor 25 through the terminal device 24 connected to the connection port 223, the wireless slave device 22 transmits a packet addressed to the center including the measured value from the narrow-area wireless communication unit 222. The packet including the measurement value transmitted from the wireless slave unit 22 is controlled by one or more wireless slave units 22 and the wireless master unit 21 in the short range wireless network N2, and center side network control connected to the wide area wireless network N1. The host computer 11 is reached via the device 12.

  The host computer 11 determines the degree of deterioration of the gas device 30 based on the measurement value notified from the terminal side. The determination method of the degree of deterioration of the gas device 30 can be appropriately set according to the type of the gas device 30, the type of the sensor 25, and the like. For example, the host computer 11 compares the measured value notified from the terminal side with a preset threshold value, and determines that the gas device 30 is degraded when the measured value is equal to or greater than the threshold value (or less than the threshold value). You may In addition, the host computer 11 stores the measured values notified from the terminal side in time series, and the newly notified measured value shows a rapid change as compared with the fluctuation of the past measured value. When it becomes, it may be judged that gas equipment 30 has deteriorated.

  The host computer 11 notifies the terminal device 24 of the determination result. At this time, the determination result transmitted from the host computer 11 is the center-side network control device 12 connected to the wide area wireless network N1, and the wireless master device 21 and one or more wireless slave devices 22 in the short range wireless network N2. To reach the terminal device 24.

  After transmitting the measurement result to the wireless slave device 22, the control unit 240 of the terminal device 24 receives the determination result notified from the host computer 11 through the wireless slave device 22 connected to the connection unit 242. It judges (step S104).

  If it is determined that it has not been received (S104: NO), the control unit 240 stands by until the determination result notified from the host computer 11 is received.

  If it is determined that it has been received (S104: YES), the control unit 240 causes the display unit 244 to display the determination result notified from the host computer 11 (step S105). For example, when the display unit 244 includes a liquid crystal display panel and receives the determination result that the gas device 30 is deteriorated, the control unit 240 displays on the liquid crystal display panel that the gas device 30 is deteriorated. Thereby prompting the user to repair or replace the gas device 30. In addition, when the display unit 244 includes an LED lamp, the control unit 240 notifies the user that the gas device 30 has deteriorated by blinking or constantly lighting the LED lamp, and the repair of the gas device 30 or The exchange may be urged.

  As described above, in the first embodiment, the notification timing of the measurement value is set according to the length of the usage period of the gas device 30. For example, when the usage period of the gas equipment 30 is short and there is a high possibility that no deterioration occurs, the number of times of communication between the terminal and the center can be reduced by setting the notification timing so that the notification interval becomes long. The load on communication resources present on the communication path can be reduced. In addition, when the usage period of the gas device 30 is long and there is a possibility that deterioration occurs, diagnosis of the gas device 30 (determination of the degree of deterioration) is performed by setting the notification timing so that the notification interval becomes short. Can be implemented at an appropriate time.

  In the present embodiment, the terminal device 24 transmits the measured value acquired from the sensor 25 to the wireless slave device 22 and notifies the host computer 11 of the measured value of the sensor 25 using the communication function of the wireless slave device 22. However, the terminal device 24 may have a function of communicating with the host computer 11. In this case, the terminal device 24 can notify the host computer 11 of the measurement value using the communication path determined by the routing function of the wireless master device 21 and the wireless slave device 22.

  In the present embodiment, the communication resource of the wireless telemetry system is shared between the terminal device 24 and the host computer 11. However, the host computer can use the home network to transmit measurement values via the Internet. 11 may be notified.

Second Embodiment
In the second embodiment, a configuration in which the terminal device 24 sets the notification frequency based on the measurement value acquired from the sensor 25 will be described.
The entire configuration of the determination system, the internal configuration of the terminal device 24, and the like are the same as in the first embodiment, and thus the description thereof will be omitted.

  FIG. 6 is a flowchart for explaining the procedure of processing performed by the terminal device 24 according to the second embodiment. When acquiring the measured value from the sensor 25 through the sensor input unit 243, the control unit 240 of the terminal device 24 determines whether the acquired measured value is a normal value (step S201). The determination as to whether the acquired measured value is a normal value is made, for example, by comparison with a preset threshold value. When the acquired measured value is larger than the threshold (or smaller than the threshold), the control unit 240 determines that the acquired measured value is a normal value.

  If it is determined that the acquired measurement value is a normal value (S201: YES), the control unit 240 notifies the host computer 11 of the measurement value according to the notification frequency defined in the timing table (step S202). The procedure for the terminal device 24 to notify the host computer 11 of the measurement value is the same as that of the first embodiment.

  On the other hand, when it is determined that the obtained measured value is not the normal value (S201: NO), the control unit 240 notifies the host computer 11 of the measured value at a notification frequency higher than the notification frequency defined in the timing table. (Step S203). For example, when the notification frequency read from the timing table according to the usage period of the gas device 30 is once a year, the control unit 240 newly adds a notification frequency (for example, once every three months) higher than that. The measurement value is notified to the host computer 11 in accordance with the newly set notification frequency. The procedure for the terminal device 24 to notify the host computer 11 of the measurement value is the same as that of the first embodiment.

  As described above, in the second embodiment, when the measurement value of the sensor 25 is not a normal value, diagnosis of the gas device 30 (determination of the degree of deterioration) is performed at an appropriate timing by raising the notification frequency to the center side. It is possible to detect the deterioration of the gas equipment 30 at an early stage.

Third Embodiment
In the third embodiment, a configuration in which a plurality of sensors are connected to the terminal device 24 will be described.
In addition, since the entire configuration of the determination system is the same as that of the first embodiment, the description thereof will be omitted.

  FIG. 7 is a block diagram for explaining the internal configuration of the terminal device 24 according to the third embodiment. The terminal device 24 according to the third embodiment includes two sensor input units 243A and 243B. The sensor input units 243A and 243B each include an input interface for inputting measurement values output from the first sensor 25A and the second sensor 25B into the terminal device 24.

  The input form of the measurement values to the sensor input units 243A and 243B can be appropriately designed according to the type of the gas device 30 to be measured, the types of the first sensor 25A and the second sensor 25B, and the like. For example, connection portions for connecting the first sensor 25A and the second sensor 25 may be provided in the sensor input portions 243A and 243B, respectively, and measurement values may be input through the respective connection portions.

  When the gas device 30 includes the first sensor 25A and the second sensor 25B and an output port for outputting measured values of the first sensor 25A and the second sensor 25B to the outside, the output port on the gas device 30 side The connection part to be connected to the sensor input part 243A, 243B may be provided, and the measurement value may be input through the connection part. Furthermore, when the first sensor 25A and the second sensor 25B include a measurement unit that measures the operation state of the gas device 30, and a transmission unit that transmits the measurement value by the measurement unit by wireless communication, the measurement transmitted by wireless communication A receiver for receiving a value may be provided in the sensor input unit 243A, 243B, and the measurement value may be input through the receiver.

  The storage unit 241 of the terminal device 24 includes a second sensor according to a threshold for determining whether or not the measurement value of the first sensor 25A (for example, a CO sensor) is a normal value, and a use period of the gas device 30. It is assumed that a timing table in which the notification frequency for notifying the host computer 11 of the measurement value of 25 B (for example, a burner sensor) is defined is stored in advance.

  FIG. 8 is a flowchart for explaining the procedure of processing performed by the terminal device 24 according to the third embodiment. When acquiring the measured value from the first sensor 25A through the sensor input unit 243A, the control unit 240 of the terminal device 24 determines whether the acquired measured value is a normal value (step S301). The determination as to whether the acquired measured value is a normal value is made, for example, by comparison with a threshold value stored in advance in the storage unit 241. When the acquired measured value is larger than the threshold (or smaller than the threshold), the control unit 240 determines that the acquired measured value is a normal value.

  If it is determined that the measured value obtained from the first sensor 25A is a normal value (S301: YES), the control unit 240 measures the measured value obtained from the second sensor 25B according to the notification frequency defined in the timing table. It notifies the host computer 11 (step S302). The procedure for the terminal device 24 to notify the host computer 11 of the measurement value is the same as that of the first embodiment.

  On the other hand, when it is determined that the measured value acquired from the first sensor 25A is not the normal value (S301: NO), the control unit 240 determines that the second sensor has a notification frequency higher than the notification frequency defined in the timing table. The measurement value obtained from 25B is notified to the host computer 11 (step S303). For example, when the notification frequency read from the timing table according to the usage period of the gas device 30 is once a year, the control unit 240 newly adds a notification frequency (for example, once every three months) higher than that. The measurement value from the sensor 25B is notified to the host computer 11 according to the newly set notification frequency. The procedure for the terminal device 24 to notify the host computer 11 of the measurement value is the same as that of the first embodiment.

  As described above, in the third embodiment, when the measurement value of the first sensor 25A is not the normal value, diagnosis of the gas device 30 is performed by increasing the notification frequency of the measurement value from the second sensor 25B different from that ( The determination of the degree of deterioration can be performed at an appropriate timing, and the deterioration of the gas device 30 can be detected early.

The terminal device 24 receives an input of an identifier for identifying the gas device 30 to be measured to the operation unit 245, and notifies the host computer 11 of the received identifier of the gas device 30 (step S401). At this time, the terminal device 24 transmits the received identifier from the connection unit 242 to the wireless slave device 22, and the center side connected to the one or more wireless slave devices 22 and the wireless master device 21 and the wide area wireless network N1. The identifier of the gas device 30 is notified to the host computer 11 via the network control device 12. Here, as an identifier of the gas device 30, a product name of the gas device 30, a serial number or the like can be used.

  When the host computer 11 receives the identifier of the gas device 30 notified from the terminal device 24 through the center-side network control device 12, the host computer 11 sets the notification frequency of the measurement value to be notified by the terminal device 24 based on the identifier Step S402). The host computer 11 may have a table in which the identifier of the gas device 30 and the notification frequency for each use period are stored in association, and the notification frequency may be set with reference to this table. The host computer 11 also has a table in which the identifier of the gas device 30 and the useful life (= n years) of the gas device 30 are stored in association with one another.
