Detailed Description

(embodiment mode)

Fig. 1 shows a block diagram of a gas appliance monitoring system in an embodiment of the present invention.

In fig. 1, a gas appliance monitoring system 1 includes a center device 20 and a gas meter 10 installed in a user house. Although a plurality of gas meters 10 are installed in each user house, only one gas meter 10 will be described in the present embodiment.

The gas meter 10 has an inflow pipe 12a and an outflow pipe 12b of gas, and a flow rate measuring unit 11 is provided on a path from the inflow pipe 12a to the outflow pipe 12 b. Further, a plurality of gas appliances 14, 15, and 16 are connected downstream of the outflow pipe 12 b.

The flow rate measuring unit 11 detects and outputs the flow rate of the gas in time series, and measures the instantaneous flow rate at predetermined intervals (for example, at intervals of 0.5 second). The storage unit 12 stores the flow rate data measured by the flow rate measurement unit 11.

The operation start detection unit 17 detects that the flow rate of the gas measured by the flow rate measurement unit 11 has increased by a predetermined flow rate (for example, 51.82L/h), detects that the operation of any one of the gas appliances 14 to 16 has started, and outputs an operation start signal of the gas appliance.

The storage unit 12 has a storage capacity for holding the flow rate of the gas measured by the flow rate measurement unit 11 as flow rate data for a predetermined time, and the storage unit 12 stores the flow rate data sequentially, and if the flow rate data exceeds the storage capacity, the storage unit stores the latest flow rate data by overwriting the flow rate data sequentially. The past flow rate data included in a predetermined period before the start point and the flow rate data measured in a predetermined period after the start point are held, starting from the time point at which the operation start signal is output from the operation start detection unit 17.

The storage unit 12 may store ambient temperature detected by the temperature detector 18, temperature data of gas, or pressure data detected by a pressure detector, not shown.

Further, the center device 20 includes: a center communication unit 21 for communicating with the meter communication unit 13 of the gas meter 10; and a data accumulating unit 22 for accumulating the received flow rate data, temperature data, and pressure data. Further, the center device 20 includes: an analysis unit 23 that performs analysis using the flow rate data accumulated in the data accumulation unit 22; and a message transmission unit 24 that creates a message to be sent to the user based on the analysis result of the analysis unit 23, and transmits the message to a terminal 30 such as a smartphone or a personal computer owned by the user. The terminal 30 may be a display terminal installed in the house of the user. The transmission method is not particularly limited, and may be wireless, wired, or a report of the meter reading result.

Fig. 2 is a graph showing an example of the measurement timing of the flow rate measurement unit 11 and the measured flow rate data when the gas appliance is a gas fan heater (gas fan heater), and shows a relationship between the timing at which the operation start detection unit 17 outputs the operation start signal and the flow rate data stored in the storage unit 12. The black dots indicate flow data measured by the flow rate measuring unit 11 every 0.5 seconds.

In the present embodiment, 5 pieces of flow rate data (data number 1 to data number 5) measured during a predetermined period Tp from the start point and 16 pieces of flow rate data (data number 6 to data number 21) measured during a predetermined period Tf after the start point are stored and held in the storage unit 12, with the output time point of the operation start signal (data number 6) as the start point.

Then, when the meter communication unit 13 receives a request signal for flow rate data from the center device 20, the flow rate data (data number 1 to data number 21) belonging to the predetermined periods Tp and Tf among the flow rate data stored in the storage unit 12 is transmitted to the center device. When transmitting the flow rate data, the flow rate data is configured to be transmitted so as to include the serial number of the gas meter 10, the measured date and time, and the like as additional data.

Next, the analysis unit 23 determines the appliance of the appliance whose operation has been started, based on the change pattern of the flow rate data at the time of the start of operation received from the gas meter 10. For example, as a typical flow rate pattern for starting the operation of the gas fan heater shown in fig. 2, since the soft ignition in which the flow rate is temporarily changed to a substantially constant flow rate occurs in the middle of reaching the maximum flow rate, the soft ignition is detected to determine that the gas appliance having started the operation is the gas fan heater. In addition, when the appliance is determined, the determination accuracy can be improved by adding the temperature data and the pressure data. The temperature data and the pressure data are stored in the data storage unit 22 together with the serial number of the gas meter 10 and the date and time when the operation is started.

Since basically one gas meter 10 is provided for each user, the serial number of the gas meter 10 can be used to identify the user. Therefore, by storing the analysis result in association with the serial number of the gas meter 10 in advance, it is possible to grasp the gas appliances installed in each user house. Further, by registering in advance an email address or the like of the user associated with the serial number of the gas meter 10, a message can be transmitted from the message transmission unit 24 to the terminal 30 of the user.

Next, the analysis content in the analysis section 23 and the message content created by the message transmission section 24 will be described using fig. 3.

When it can be determined by the above-described appliance determination that the use of the gas Fan Heater (FH) has started from autumn to winter, a message "the use of FH. has started since yesterday will be ○○% better than ordinary costs" is transmitted to promote the use of gas.

Item B is an item for detecting a situation where the gas fan heater is not used although it has come to winter and transmitting a message corresponding thereto. Transmit "this winter does not use FH. Heating is more cost-effective than air conditioning in this season. "to facilitate the use of gas.

Item C is an item that detects a failure or degradation of the gas appliance and transmits a message corresponding thereto. For example, the flow rate change (broken line) of the same gas fan heater from the start of the operation this time is compared with the flow rate change (solid line) of the last year stored in the data accumulation unit 22. Thus, it is judged that some abnormality may be generated in the gas fan heater according to the difference such as the time extension of the soft ignition or the maximum flow rate reduction, and "FH ignition is deteriorated as compared with the last year" is transmitted. It is recommended to check/replace the gas appliance. "to remind the user of the attention.

The term "FH operation time exceeds ○○ hours" is recommended to replace the filter, and the user is notified of the inspection/replacement of the equipment ".

Item E is an item for predicting a failure of the gas appliance and transmitting a message corresponding thereto. By analyzing the flow rate data stored in the data storage unit 22 in detail, the deterioration state and the change in timing of the gas appliance are determined, and the risk of future failure is notified in advance. For example, "a traffic pattern in which an abnormality is detected is transmitted. After years there is a risk of failure. "is received.

Item F is an item that facilitates replacement. The model of the gas appliance is determined by appliance determination, and the latest model is recommended when the model is an old model. For example, delivering "the latest gas fan heaters is more energy efficient and cost effective to replace. "such a message.

As described above, according to the present embodiment, the center device 20 analyzes the flow rate data and the like received from the gas meter 10, creates various messages related to the use of the gas appliance, and transmits the messages to the user as meaningful information.
