Description

The present invention relates to a gas shutoff device management system capable of transplanting and setting various information from an old gas shutoff device to a new gas shutoff device when the gas shutoff device is replaced.

Conventionally, when replacing a gas shutoff device, it has been common to use a dedicated setting device. For example, when the gas shutoff device to be replaced (installed and to be replaced) is the old gas shutoff device and the gas shutoff device to be replaced (newly installed) is the new gas shutoff device, the setting device is used. The information on the old gas shutoff device was read, and then the new gas shutoff device was registered by communicating with the center. However, in such a conventional method, it has been troublesome to connect the line to the center by using a dedicated setting device, or to connect the setting device to each of the old and new gas shutoff devices and repeat the setting.

Therefore, Patent Document 1 discloses a gas shutoff device that can communicate with another gas shutoff device via a signal line and includes a transplant setting means for reading and transplanting a set value. Specifically, the old gas shutoff device and the new gas shutoff device are communicably connected by a signal line, and the setting information set in the old gas shutoff device is read out by the transplant setting means of the new gas shutoff device. It is newly set as the setting information of the new gas shutoff device. This makes it possible to transfer the setting information from the old gas shutoff device to the new gas shutoff device without using a dedicated setting device.

However, in the gas shutoff device disclosed in Patent Document 1, although the setting information can be transplanted, various information other than the setting information, particularly various information (learning information) learned by installing the gas shutoff device is transplanted. Can not do it.

The present invention has been made to solve such a problem, and to provide a management system including a gas shutoff device and a center, and capable of transplanting learning information as well as setting information of the gas shutoff device. The purpose.

Based on the monitoring result of the gas appliance monitoring unit, the gas shutoff unit is operated to shut off the gas flow path, and the usage state of the gas appliance, which is the basis of the monitoring result, is used as the learning information to shut off the gas. When storing in the storage unit and replacing any of the plurality of gas shutoff devices, the installed one to be replaced is regarded as the old gas shutoff device, and the newly installed one is referred to as the new gas shutoff device. At that time, the mobile terminal acquires at least the old device individual information which is the individual information of the old gas shutoff device and the new device individual information which is the individual information of the new gas shutoff device, and transmits the individual information to the center.

Usually, learning information with a large amount of data requires more time to be ported than setting information. According to the above configuration, only the acquisition and transmission of individual information is required at the exchange site, and the transplantation work itself is carried out by communication from the center. Therefore, after exchanging the gas shutoff device, the learning information can be easily transplanted by communication at an arbitrary timing.

It may be composed of an internal memory, an external storage device, or the like.

The gas shutoff device 20 includes a gas cutoff control unit 21, a gas cutoff communication unit 22, a gas cutoff storage unit 23, a flow rate measurement unit 24, a gas cutoff unit 25, a gas appliance monitoring unit 26, a gas appliance discrimination unit 27, and the like. ..

The gas cutoff control unit 21 controls the operation of the gas cutoff device 20, and the gas cutoff communication unit 22 communicates with at least the center 10 via a communication line under the control of the gas cutoff control unit 21. The gas shutoff storage unit 23 stores various information used for the operation of the gas shutoff device 20. As will be described later, the various types of information include setting information set in the gas shutoff device 20 and learning information generated by the operation of the gas shutoff device 20.

The specific configurations of the gas cutoff control unit 21, the gas cutoff communication unit 22, and the gas cutoff storage unit 23 are not particularly limited, and are an arithmetic unit such as a CPU of a known microcomputer or a microcontroller, and a known wired or wireless device, respectively. It may be composed of a communication module, an internal memory, and the like.

The flow rate measuring unit 24 measures the gas flow rate in the gas flow path, and in the present embodiment, for example, an ultrasonic flow rate measuring device that measures the flow rate of a fluid such as gas by using ultrasonic waves is used. Has been done. As a typical ultrasonic flow rate measurement method, a method using a propagation time difference method can be mentioned. The specific configuration of the ultrasonic flow rate measuring instrument using the propagation time difference method is not particularly limited, and a known configuration can be preferably used. Further, as the flow rate measuring unit 24, an electronic flow rate measuring device such as a heat flow sensor or a full-dick type can be used in addition to the ultrasonic flow measuring device.

As a result of monitoring the gas flow rate measured by the flow rate measuring unit 24 by the gas appliance monitoring unit 26, the gas shutoff unit 25 operates under the control of the gas shutoff control unit 21 when it is determined that there is some abnormal state or the possibility thereof. And cut off the gas flow in the gas flow path. The specific configuration of the gas shutoff unit 25 is not particularly limited, and examples thereof include a configuration including a solenoid type solenoid valve or a motor-driven valve.

The gas appliance monitoring unit 26 monitors the usage state of the gas appliance connected to the pipe based on the gas flow rate measured by the flow rate measuring unit 24. The method of monitoring the usage state by the gas appliance monitoring unit 26 is not particularly limited, but for example, by monitoring the flow rate of the gas flowing into the gas appliance over time, it is determined whether or not the usage state of the gas appliance is abnormal. Can be mentioned. Specific abnormalities include whether or not the gas appliance has been used for a long time, whether or not the gas flow rate has reached an abnormal value for a certain period of time, and whether or not the gas flow rate changes over time based on the gas flow rate.

The method for discriminating the gas appliance by the gas appliance discriminating unit 27 is not particularly limited, and examples thereof include a configuration in which the type of the gas appliance is discriminated based on the discriminant value of the gas flow rate corresponding to the type of the gas appliance.

In the present disclosure, the mobile terminal 30 can publicly use various commonly used information terminal devices. Typical examples include mobile phone terminals such as smartphones, other information terminals that can communicate (tablets, etc.), portable personal computers, and the like. The communication between the mobile terminal 30 and the center 10 may be executed using a general communication module, may be executed using dedicated application software, or may be executed using a dedicated communication line. It may be executed using a module. Further, the communication terminal 30 may be configured to be able to communicate with the gas shutoff device 20 if necessary.

In the present embodiment, the fuel cell 41, the gas table 42, and the fan heater 43 are illustrated as gas appliances, but the fuel cell 41 is premised on being constantly operated for power generation, and is a gas as a cooking appliance. Since the table 42 operates only at the time of cooking, the usage time is relatively short, and the fan heater 43, which is a heating appliance, operates while heating the room, so that the usage time is relatively long. Therefore, by setting the discrimination value of the gas flow rate according to these characteristics in advance, the type of the gas appliance can be discriminated from the gas flow rate.

The gas appliance monitoring unit 26 and the gas appliance discrimination unit 27 have, for example, a functional configuration of a microcomputer or a microcomputer constituting the gas cutoff control unit 21 (the arithmetic unit functioning as the gas cutoff control unit 21 is the gas cutoff storage unit 23 (or The configuration may be realized by operating according to a program stored in another storage means), but it may be configured as a logic circuit using a known switching element, subtractor, comparator or the like.

In the present disclosure, the gas shutoff device 20 does not have to include the gas appliance discriminating unit 27. However, by providing the gas appliance discriminating unit 27, the gas appliance monitoring unit 26 monitors the usage state of the gas appliance after grasping the type of the gas appliance. Therefore, for example, the accuracy of determining an abnormality in the usage state. Can be improved.

In the gas shutoff device management system according to the present disclosure, the center 10 may have a configuration other than the center control unit 11, the center communication unit 12, and the center storage unit 13. Similarly, the gas shutoff device 20 may have a configuration other than the gas cutoff control unit 21, the gas cutoff communication unit 22, the gas cutoff storage unit 23, the flow rate measuring unit 24, the gas cutoff unit 25, and the gas appliance monitoring unit 26. .. For example, the center 10 or the gas shutoff device 20 may each include a known display unit, input unit, timekeeping unit, notification unit, and the like. Further, in the case of the gas shutoff device 20, as an example of the input unit, a return switch or the like for releasing the cutoff from the state in which the gas cutoff unit 25 operates and the gas flow path is cut off may be provided.

Next, in the gas shutoff device management system according to the present disclosure, regarding the transplantation of various information when exchanging the old gas shutoff device 20A, which is any one of the plurality of gas shutoff devices 20, with the new gas shutoff device 20B. In addition to FIGS. 1 and 2, a specific description will be given with reference to FIG.

The gas shutoff device 20 replaces the gas shutoff device 20 when the certification expiration period specified by law elapses or when some trouble occurs in the gas shutoff device 20 itself. At this time, it is necessary to transplant the setting information stored in the gas shutoff storage unit 23 of the old gas shutoff device 20A to the new gas shutoff device 20B. As this setting information, for example, various setting conditions (patent documents) for monitoring the usage state of the gas appliance by the gas appliance monitoring unit 26 in the gas consumer (gas consumer) in which the old gas shutoff device 20A is installed. (Refer to the setting contents of 1).

Here, as the gas shutoff unit 25 is operated based on the monitoring result of the gas appliance monitoring unit 26 to shut off the gas flow path, the gas cutoff control unit 21 uses the gas appliance which is the basis of the monitoring result. Can be stored in the gas shutoff storage unit 23 as learning information. Specific learning information includes, for example, a security state (for example, usage time cutoff value, total / increased flow rate cutoff value) optimized according to the usage status of gas appliances by gas consumers (gas consumers). Can be mentioned. Alternatively, if the old gas shutoff device 20A includes the gas appliance discrimination unit 27, the type of gas appliance that is the discrimination result of the gas appliance discrimination unit 27 may be used as learning information.

It is not necessary to transfer such learning information from the old gas shutoff device 20A before the replacement to the new gas shutoff device 20B replaced. This is because the same learning information can be obtained by continuing the monitoring by the gas appliance monitoring unit 26 after the operation of the new gas shutoff device 20B is started. However, since it takes a considerable period of time for the replaced new gas shutoff device 20B to acquire the same learning information as the old gas shutoff device 20A, the new gas shutoff device 20B has a certain period immediately after the replacement. In a situation where sufficient learning information cannot be obtained, the gas appliance monitoring unit 26 will monitor the gas appliance monitoring unit 26. Therefore, it is desirable that not only the setting information but also the learning information can be transplanted to the new gas shutoff device 20B.

However, with the conventional gas shutoff device, although the setting information can be transplanted, the learning information cannot be transplanted. In particular, learning information has a relatively large amount of data compared to setting information, and the data structure tends to be complicated. Therefore, when trying to transplant such learning information at an exchange site as in the past, the porting work itself May become significantly complicated. On the other hand, in the gas shutoff device management system according to the present disclosure, the center 10 carries out the transplantation of various information itself, and the mobile terminal 30 is used to support the transplantation by the center 10. This makes it possible to simplify the work required for transplanting various information when replacing the gas shutoff device 20.

Specifically, first, as shown in FIG. 3A, at the site where the old gas shutoff device 20A is replaced with the new gas shutoff device 20B, for example, the portable terminal 30 owned by the replacement worker is used to replace these gas shutoff devices. The individual information of 20A and 20B is acquired and transmitted to the center 10. In FIGS. 3A and 1, the acquisition of individual information by the mobile terminal 30 is schematically shown by a broken line arrow. Further, in FIG. 3A, the transmission of individual information from the mobile terminal 30 to the center 10 is indicated by a black block arrow along the dotted communication line.

The method for acquiring individual information of the gas shutoff devices 20A and 20B by the mobile terminal 30 is not particularly limited, and communication is performed between the mobile terminal 30 and the gas cutoff communication unit 22 of the gas shutoff devices 20A and 20B via a communication line. However, preferably, manual input to the mobile terminal 30, reading by a bar code, or reading by a QR code (registered trademark) can be mentioned. By using manual input or code input as described above, individual information of these gas shutoff devices 20A and 20B can be obtained without communicating the mobile terminal 30 and the gas shutoff devices 20A and 20B via a communication line. It can be easily obtained.

For example, if individual information is displayed on the outer surface of the gas shutoff devices 20A and 20B (including direct printing or labeling, sticking of a plate, etc.), the replacement worker manually inputs the individual information into the mobile terminal 30. be able to. Further, if a one-dimensional bar code indicating individual information or a two-dimensional bar code such as a QR code (registered trademark) is displayed on the outer surface of the gas shutoff devices 20A and 20B, the replacement worker can use the camera of the mobile terminal 30. By photographing and recognizing these barcodes, individual information can be easily acquired. For convenience of explanation, the individual information of the old gas shutoff device 20A is referred to as "old device individual information", and the individual information of the new gas shutoff device 20B is referred to as "new device individual information".

The old device individual information and the new device individual information transmitted from the mobile terminal 30 to the center 10 are stored in the center storage unit 13 by the center control unit 11 of the center 10. Then, as shown in FIG. 3B, the center control unit 11 of the center 10 calls the old gas shutoff device 20A via the communication line by the center communication unit 12 based on the stored old device individual information ( Call). In FIGS. 3B and 3D, the calls of the gas shutoff devices 20A and 20B are indicated by double-line arrows, and the reading or writing of various information is indicated by black block arrows.

When communication becomes possible between the center 10 and the old gas shutoff device 20A, the center control unit 11 reads various information stored from the gas cutoff storage unit 23 of the old gas shutoff device 20A by the center communication unit 12 and reads various information. It is stored in the center storage unit 13 as "various information of the old device" associated with the individual information of the old device. As described above, the various information includes not only setting information but also learning information. Reading and storage by the center 10 is performed via a communication line. Therefore, the exchange worker at the site does not need to read various information, and can proceed with the preparation for the exchange work.

Next, as shown in FIG. 3C, the old gas shutoff device 20A is removed by the replacement worker, and the new gas shutoff device 20B is newly installed. Then, after the replacement, as shown in FIG. 3D, the center control unit 11 of the center 10 is connected to the new gas shutoff device 20B by the center communication unit 12 based on the new device individual information stored in the center storage unit 13. Communicate to call (call) the new gas shutoff device 20B. When communication becomes possible between the center 10 and the new gas shutoff device 20B, the center control unit 11 writes various information of the old device stored in the center storage unit 13 into the gas shutoff storage unit 23 of the new gas shutoff device 20B.

Writing of various information of the old device by the center 10 is carried out via a communication line. Therefore, the replacement worker at the site does not need to write various information of the old device, and can be separated from the site in a timely manner when the replacement work is completed. When the writing of various information of the old device to the new gas shutoff device 20B is completed, the porting work of various information is completed.

In the example shown in FIG. 3B, the center 10 stores the received old device individual information and the new device individual information, and then reads various information of the old device from the old gas shutoff device 20A to read the old device individual information. Various information on the old device is configured in association with the information, but the present disclosure is not limited to this. For example, the center control unit 11 of the center 10 reads various information from each gas shutoff device 20 in a timely manner in the process of managing the plurality of gas shutoff devices 20, and from among the plurality of various information read in advance. , Various information of the corresponding gas shutoff device 20 may be selected based on the old device individual information received from the mobile terminal 30, and various information of the old device may be configured in association with the old device individual information.

As described above, according to the present disclosure, when any one of the plurality of gas shutoff devices 20 constituting the gas shutoff device management system is replaced, the mobile terminal 30 is used to provide individual information on the old and new gas shutoff devices 20A and 20B. Will be acquired and transmitted to the center 10 in advance. Therefore, at the exchange site of the gas shutoff devices 20A and 20B, it is only necessary to acquire and transmit the individual information of each, and the transplantation of various information can be executed by the communication from the center 10. As a result, when exchanging the gas shutoff devices 20A and 20B, the work required for transplanting various information can be simplified.

Furthermore, the various information to be transplanted includes not only setting information but also learning information having a relatively large amount of data. Normally, learning information with a large amount of data requires more time to be transplanted than the setting information, but as described above, at the exchange site, only the acquisition and transmission of individual information by the mobile terminal 30 is required, and the transplanting work itself is performed by the center 10. It is carried out by communication from. Therefore, after exchanging the gas shutoff devices 20A and 20B, various information including learning information can be easily transplanted by communication at an arbitrary timing. For gas consumers (gas consumers), the new gas shutoff device 20B operates the gas appliance in a optimized state based on the learning information before replacement without having to operate for a certain period of time to acquire learning information again. It becomes possible to monitor security.

In addition, by including the type of gas appliance in the learning information, the gas appliance owned by the gas consumer (gas consumer) can be managed even in the new gas shutoff device 20B after replacement. Further, the gas appliance monitoring unit 26 of the new gas appliance 20B will monitor the usage status of the gas appliance after grasping the type of the installed gas appliance, as in the case of the old gas appliance 20A before replacement. .. Therefore, in the new gas shutoff device 20B as well as in the old gas shutoff device 20A, it is possible to improve the accuracy of determining an abnormality in the usage state.
