Description

  The present invention includes a plurality of facility devices fixedly installed in a building, is capable of information communication with each of the facility devices via a communication line, and has access authority to the facility devices. The present invention relates to a device information management system including a management server device that stores authentication information associated with a facility device and receives and stores device operation information indicating an operation state of the facility device from each of the facility devices.

  Patent Document 1 describes a device information management system that includes a facility server that is fixedly installed in a building such as a house, and that includes a management server device that can communicate information with the facility device via a communication line. Has been. In this device information management system, the facility device transmits device operation information indicating its own operation status to the management server device, and the management server device stores the device operation information. Then, when there is an access from a user communication device used by a user of the facility device, the management server device transmits the device operation information to the user communication device to allow the user to browse. As a result, the user can confirm how the equipment is operating from a remote location. In this device information management system, the management server device mediates transmission of control command information from the user communication device to the facility device. As a result, the user can control the operation of the equipment from a remote location.

  Incidentally, in the device information management system as described in Patent Document 1, it is normal to permit browsing of device operation information of facility equipment and remote control of the facility device only to authorized users.

  In the device information management system described in Patent Document 2, the facility device includes a device such as a water heater and an operation terminal (a so-called remote control device) used when the device is used. The management server device manages registration of access authority for the equipment by the user. If a user who has a building as a residence has access authority to the equipment installed in the building, he / she accesses the management server device using the user communication device used by the user. And the remote control of the equipment (hot water heater) can be performed via the management server device.

In addition, when the original user leaves, if the authentication information stored in the management server device and associated with the user who has access authority to the equipment is not deleted, the original Can remotely control the equipment. In that case, the equipment may be operated in a manner not intended by the next transferee, that is, the true user.
In order to avoid the occurrence of such a problem, in the system described in Patent Document 2, when the facility device detects that the power supply has been stopped for a certain period of time or more, it considers this to be a retreat, and from the user communication device. It is configured to shift to a remote operation disabled mode in which remote operation is rejected.

JP 2004-005496 A Japanese Patent No. 4781845

  In an apartment house or the like, the equipment may continue to be energized even if the original user leaves. For example, in an apartment house, Internet communication devices installed in each house are installed as shared equipment, and it is possible that the Internet communication device will continue to be energized even if the original user leaves. . Therefore, in the system of Patent Document 2, there is a possibility that it is not determined that the original user has moved out when the energization of the equipment (Internet communication device) continues even if the original user leaves. There is.

  The present invention has been made in view of the above-described problems, and its purpose is to simply configure the loss of access authority to a facility device when the use of the facility device is stopped due to the user leaving or the like. The point is to provide a device information management system that can be realized by the system.

In order to achieve the above object, the feature configuration of the equipment information management system according to the present invention includes a plurality of equipment equipment fixedly installed in a building, and information between each equipment equipment via a communication line. Authentication information in which communication is possible and a user having access authority to the equipment and the equipment is associated is stored, and equipment operation information indicating an operation status of the equipment is stored in the equipment A device information management system comprising a management server device that receives and stores each of
An information collecting unit that collects information for determination that can be used to determine whether or not a utility using device that can be used in the same building as the equipment by the user is in an unusable state;
The management server device receives the determination information collected by the information collection unit via the communication line, and when there is an access via the communication line from a user communication device used by the user, The facility device for which the user has access authority is identified based on the authentication information, and the control command information from the user communication device to the facility device for which the user has access authority At least one of mediating transmission and browsing of the device operation information of the facility device to which the user has access authority using the user communication device When it is determined that the utility using device is in an unusable state based on the determination information, the unusable state by the user included in the authentication information It lies in performing rights disappearance treatment to lose the access to the equipment utilized in the same the building to be said utility equipment used.

  According to the above characteristic configuration, the management server device receives control command information to the equipment device when the user has access authority when accessed from the user communication device, and the device Permit at least one of browsing driving information. That is, if the user can access the management server device via the communication line, the user can remotely control the equipment and browse the equipment operation information.

In addition, if a utility using device that can be used in the same building as the equipment by the user is in an unusable state, it can be said that the user has left the building. For example, when a user leaves the building and a supply path for utilities such as gas and water is closed, the utility use device becomes unusable. Therefore, if the user of the facility equipment has left the building, it is preferable to lose the access authority for the facility device by the user.
Therefore, when the management server device receives the determination information collected by the information collection unit via the communication line and determines that the utility using device is in an unusable state based on the determination information, it is included in the authentication information. Permission loss processing is performed to lose access authority to facility equipment used in the same building as utility use equipment in a disabled state by a registered user. In other words, the management server device determines whether or not to perform the authority loss processing only by monitoring the presence or absence of an event that may occur when the user of the facility device leaves (that is, an event that the utility using device is in an unusable state). Can be determined.
Therefore, it is possible to provide a device information management system that can realize the disappearance of access authority to a facility device with a simple configuration when the use of the facility device is stopped due to the user leaving or the like.

  Another characteristic configuration of the device information management system according to the present invention is that the facility device stores a user who has access authority to the device device, and is connected to the user communication device. Accepting the control command information to the user from the user communication device used by the user if the user has access authority to the user when accessed via a private network; and The user is allowed to view at least one of the device operation information using the user communication device.

  According to the above characteristic configuration, when the facility device is accessed from the user communication device via the private network to which the facility device is connected, if the user has an access right for the user, Is allowed to receive control command information from the user communication device used by the user and to allow the user to browse the device operation information using the user communication device. That is, for example, if the user can connect to the private network from the user communication device while staying at the building, the user can access the facility device without going through the management server device.

  According to still another characteristic configuration of the device information management system according to the present invention, the facility device stores a user who has an access right to itself, and is used by the user who has an access right to itself. The point is that the user communication device transmits the access to the management server device through the private network to which the user communication device is connected.

  According to the above characteristic configuration, the management server device can know that the user has accessed the equipment device by connecting to the private network from the user communication device while staying in the building, for example.

  According to still another characteristic configuration of the device information management system according to the present invention, the management server device transmits information indicating that access authority has been lost by the authority loss processing to the user communication device of the user. In the point.

  According to the above characteristic configuration, the user can know that the access authority has been lost by the authority loss process.

  Still another characteristic configuration of the device information management system according to the present invention is that the utility using device is a device using at least one of gas and water utilities, and the information collecting unit is provided in a utility supply path. The utility supply pressure in the utility supply path is collected as the determination information on the side closer to the utility using device than the main plug.

  If the utility supply path such as gas or water supply is closed and the utility equipment becomes unusable due to the user leaving the building, the utility supply pressure decreases monotonously or completely fluctuates downstream from the supply source plug. It is thought not to. Therefore, it is possible to determine whether or not the utility using device is in an unusable state with reference to the utility supply pressure measured on the side closer to the utility using device than the supply source plug provided in the utility supply path.

  Still another characteristic configuration of the device information management system according to the present invention is that the utility using device is a device using at least one of gas and water utilities, and the information collecting unit is provided in a utility supply path. The utility supply amount per unit time in the utility supply path is collected as the determination information on the side closer to the utility using device than the main plug.

  If the user moves out of the building and the utility supply path such as gas and water is closed and the utility equipment becomes unusable, the utility supply volume downstream from the supply source plug will be zero. It is done. Therefore, it is possible to determine whether or not the utility using device is in an unusable state with reference to the utility supply amount measured on the side closer to the utility using device than the supply source plug provided in the utility supply path.

  Still another characteristic configuration of the device information management system according to the present invention is such that the management server device transmits the control command information to the utility using device to perform the forced operation of the utility using device, and performs the forced operation. And determining whether or not the utility using device is in an unusable state based on the information for determination collected by the information collecting unit before and after.

If the user has not moved away from the building but has been absent for a long period of time, for example, due to travel, the user has moved away from the building and the supply source plug regarding the utility supply pressure and utility supply amount collected by the information collection unit There may be no change at all as in the case where is closed.
However, in this feature configuration, the management server device transmits the control command information to the utility using device to cause the utility using device to forcibly operate. In other words, if the user is simply absent for a long period of time, the utility supply pressure and utility supply amount collected by the information collection unit will fluctuate before and after forced operation (before and after sending control command information). May be seen. On the other hand, if the user leaves the building and the supply source plug is closed, it is considered that there is no change in the utility supply pressure and the utility supply amount collected by the information collection unit. As a result, whether or not the utility using device is in an unusable state based on the judgment information collected by the information collecting unit before and after the control command information is transmitted to the utility using device and forced operation of the utility using device is performed. Can be determined.

It is a figure which shows the structure of an apparatus information management system. It is a figure which shows the example of a display screen of a user communication apparatus. It is a figure which shows the example of a display screen of a user communication apparatus.

A device information management system according to the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a device information management system. As shown in the figure, the device information management system includes a plurality of facility devices 10 fixedly installed in the building 3 and is capable of information communication with each of the facility devices 10 via the communication line 1. A device 2 is provided. The user communication device T illustrated in FIG. 1 is a mobile communication terminal such as a mobile phone or a smartphone used by a user who is a resident of the building 3 or a computer device having a communication function. FIG. 1 depicts an example in which two buildings 3 (3A, 3B) are drawn and one facility device 10 (10A, 10B) is provided in each building 3 (3A, 3B). There are no restrictions on the number of buildings 3 installed and the number of equipment 10 installed in each building 3.

  In each building 3 (3A, 3B) such as a dwelling unit, an internal private network 14 (14A, 14B) and an external communication line 1 are connected using a router 13 (13A, 13B). The equipment 10 (10A, 10B) is connected to the external communication line 1 via the router 13 (13A, 13B). In the example illustrated in FIG. 1, the facility device 10 includes a fuel cell 12 and a remote control device 11 that performs settings, operation commands, and the like of the fuel cell 12. The remote control device 11 is also a communication device having a function of performing information communication with the outside while being connected to the communication line 1 via the router 13. The remote control device 11 also has an information storage function, an information processing function, and the like. Note that the example of the equipment 10 is not limited to the combination of the fuel cell 12 and the remote control device 11, but a combination of various devices and the remote control device 11 that performs setting of the device, an operation command, and the like. It can be used as the equipment 10.

  In addition, in this embodiment, utility use equipment 15 (15A, 15B) is installed in each building 3 (3A, 3B). That is, the utility using device 15 is a device that a user can use in the same building 3 as the facility device 10. The utility using devices 15 (15A, 15B) are connected to the external communication line 1 via the private network 14 (14A, 14B) and the router 13 (13A, 13B). Specifically, the utility using device 15 is a single device or a combination of a plurality of devices using at least one of gas and water utilities. For example, as the utility using device 15 that uses only gas, an anti-freezing device (specifically, a gas supply valve to the combustor, for combustion, which burns gas and uses the heat of combustion for preventing freezing of water) Air supply blower, water circulating pump, etc.). Moreover, as the utility use apparatus 15 using only a water supply, there exists an apparatus (supply valve etc. provided in the water supply path to a bathtub) etc. for performing additional water to a bathtub. Furthermore, as the utility using device 15 that uses both gas and water, there are devices for adding hot water to the bathtub (gas supply valve to the combustor, blower for supplying combustion air, hot water supply path to the bathtub, etc. Etc.) and the like. Further, when gas or water is used for the operation of the fuel cell 12 described above, the fuel cell 12 can be regarded as the utility using device 15. That is, the facility device 10 may be the utility using device 15.

  A utility is supplied to the utility using device 15 via the utility supply path 17. Usually, a supply source plug 18 is installed in the middle of the utility supply path 17, and when the user moves into (moves into) the building 3, the supply source plug 18 is opened, and the user leaves the building 3. When that happens, the closure is performed. Further, a meter M that can measure the utility supply amount per unit time in the utility supply path 17 is installed on the side closer to the utility using device 15 than the supply source plug 18 provided in the utility supply path 17. Further, a pressure gauge P capable of measuring the utility supply pressure in the utility supply path 17 is installed on the side closer to the utility using device 15 than the supply source plug 18 provided in the utility supply path 17. The information of the utility supply amount and the information of the utility supply pressure are collected by the information collection unit 16 (16A, 16B). The information collection unit 16 (16A, 16B) is connected to the external communication line 1 via the private network 14 (14A, 14B) and the router 13 (13A, 13B).

  The management server device 2 performs information communication between the equipment device 10 and the information collection unit 16 and information communication with the user communication device T. The management server device 2 is realized using a computer having an information communication function, an information storage function, an arithmetic processing function, and the like. The functions of the management server device 2 include information presentation processing, remote control processing, and information collection processing. The information presentation process is a function of receiving and storing device operation information indicating the operation status of each facility device 10 from each of the facility devices 10 and providing it to the user communication device T. The remote control process is a function that mediates transmission of control command information from the user communication device T to the facility device 10. The information collection process is a function for receiving and storing information collected by the information collection unit 16.

  Further, the management server device 2 may collect information indicating the operation status of the utility using device 15. Further, remote control from the management server device 2 to the utility using device 15 may be performed. That is, the management server device 2 can also transmit the control command information to the utility using device 15 as described above via the communication line 1 to cause the utility using device 15 to be forcibly operated.

  The information presentation process and the remote control process described above are provided only to specific users (users having access authority). For example, the information presentation process and the remote control process for the equipment 10A are provided only to the user who is a resident of the building 3A, for example. Specifically, the management server device 2 stores authentication information in which a user who has access authority to the facility device 10A and the facility device 10A are associated with each other. Similarly, the management server device 2 stores authentication information in which a user who has access authority to the equipment device 10B is associated with the equipment device 10B.

  In the example of the authentication information illustrated in FIG. 1, the management server device 2 stores a user a1 as a user who has access authority to the equipment device 10A. In addition, the management server device 2 stores a user b1 and a user b2 as users who have access authority to the equipment 10B. The user a1 uses the user communication device Ta1 (T), the user b1 uses the user communication device Tb1 (T), and the user b2 uses the user communication device. Tb2 (T). Then, when there is an access through the communication line 1 from the user communication device T used by the user, the management server device 2 identifies the equipment device 10 to which the user has access authority based on the authentication information. Identify and mediate transmission of control command information from the user communication device T to the facility device 10 to which the user has access authority, and the facility device to which the user has access authority The device operation information is configured to permit at least one of the user's browsing of the device operation information using the user communication device T.

  As a method for identifying whether or not the user who has accessed the management server device 2 has the access authority, the user who has accessed using the user communication device T can input a password or the like. When the input result is correct, a method for identifying that the user has access authority, or device identification information of the user communication device T used by the user is acquired, and the device identification information is already registered. In some cases, various authentication methods such as a method of identifying that the user has access authority can be used.

  In the present embodiment, each facility device 10 transmits information to the management server device 2 for each set period while power is supplied. The information that each facility device 10 transmits to the management server device 2 is, for example, device operation information that indicates the operation status of the facility device 10. And the management server apparatus 2 receives and memorize | stores the apparatus operation information which shows the operating condition of the equipment 10 from each of the equipment 10.

  In the example illustrated in FIG. 1, the management server device 2 includes, as device operation information, information about the power generation status of the fuel cell 12A as the facility device 10A and information about the power generation status of the fuel cell 12B as the facility device 10B. I remember it. For example, as information on the power generation status, the current state of whether power generation is currently being performed or stopped, the current power generation, the amount of power generation in the past predetermined period, the past power generation or the transition of power generation amount There are various information such as the presence or absence of failure.

  In addition, the management server device 2 stores use device information related to the combination of the facility device 10, the utility use device 15, and the information collection unit 16 installed in each building 3. As a result, when the management server device 2 receives information from the information collection unit 16, the management server device 2 can determine which building 3 collects the information.

  FIG. 2 is a diagram illustrating an example of a display screen of the user communication device T. As shown in the figure, the display screen of the user communication device T shows the operating status of the fuel cell 12 as the facility device 10. Specifically, the user communication device T displays that the fuel cell 12 is currently generating power, and the transition of the past generated power of the fuel cell 12. In addition, when the user makes a selection input to the “remote control” button 20, it is possible to shift to a mode for instructing remote control to the fuel cell 12 as the equipment 10.

  As shown in FIG. 1, each user can access the equipment 10 used by the user by using the user communication device T without going through the management server device 2. In other words, the facility device 10 stores users who have access authority to itself, and when the user communication device T is accessed via the private network 14 to which the facility device 10 is connected, If the user has access authority to himself / herself, the user receives control command information from the user communication device T used by the user, and the user receives the device operation information from the user communication device T. Allow at least one of browsing using. In addition, the facility device 10 informs the management server device 2 that access has been made from the user communication device T used by a user who has access authority to the facility device 10 via the private network 14 to which the facility device 10 is connected. Send. As a result, the management server apparatus 2 can know that the user has connected to the private network 14 from the user communication device T and accessed the facility device 10 while staying at the building 3, for example.

  Next, access authority management control performed by the management server device 2 will be described. The management server device 2 performs this access authority management control in parallel while constantly performing the above-described information presentation processing, remote control processing, and information collection processing.

  In the present embodiment, the information collection unit 16 transmits the collected information to the management server device 2 every predetermined period. Here, the information collecting unit 16 is configured to be able to transmit information to the management server device 2 by supplying power even after the user leaves the building 3. In the access authority management control, the management server device 2 determines whether or not the utility using device 15 that allows the user to use the information received from the information collecting unit 16 in the same building 3 as the facility device 10 is unusable. This is used as determination information that can be used to determine whether or not. When the management server device 2 determines that the utility using device 15 is in an unusable state based on the determination information, the management server device 2 uses the utility using device 15 in the unusable state by the user included in the authentication information. An authority loss process for losing access authority to the equipment 10 used in the same building 3 is performed.

  For example, the information collecting unit 16 collects the utility supply pressure in the utility supply path 17 as determination information on the side closer to the utility using device 15 than the supply source plug 18 provided in the utility supply path 17. Therefore, when the user leaves the building 3 and the supply source plug 18 such as gas or water is closed and the utility using device 15 becomes unusable, the utility supply pressure is monotonous downstream from the supply source plug 18. It is considered that there is no decrease or no change at all. Therefore, the management server device 2 refers to the utility supply pressure measured on the side closer to the utility use device 15 than the supply source plug 18 provided in the utility supply path 17, and whether the utility use device 15 is in an unusable state. A determination of whether or not can be made. Then, the management server device 2 refers to the utilization device information, and performs authority loss processing for losing the user's access authority to the facility device 10 that is used in the same building 3 as the utility use device 15 in the unusable state. Do. Thereby, for example, after a resident (user) leaves the building 3, the resident cannot perform remote control on the equipment 10.

  Alternatively, the information collecting unit 16 collects the utility supply amount per unit time in the utility supply path 17 as determination information on the side closer to the utility using device 15 than the supply source plug 18 provided in the utility supply path 17. Therefore, when the user leaves the building 3 and the supply source plug 18 such as gas or water is closed and the utility using device 15 becomes unusable, the utility supply amount downstream of the supply source plug 18 is It will be zero. Therefore, the management server device 2 refers to the utility supply amount measured on the side closer to the utility use device 15 than the supply source plug 18 provided in the utility supply path 17, and whether the utility use device 15 is in an unusable state. A determination of whether or not can be made. Then, the management server device 2 refers to the utilization device information, and performs authority loss processing for losing the user's access authority to the facility device 10 that is used in the same building 3 as the utility use device 15 in the unusable state. Do. Thereby, for example, after a resident (user) leaves the building 3, the resident cannot perform remote control on the equipment 10.

  It is possible to appropriately set how the management server device 2 analyzes the utility supply pressure and the utility supply amount to determine whether or not the utility using device 15 is in an unusable state.

  As described above, it is possible to provide a device information management system that can realize the disappearance of access authority to a facility device 10 with a simple configuration when the use of the facility device 10 is stopped due to the user leaving or the like.

<Another embodiment>
<1>
In the above embodiment, the configuration of the device information management system has been described with a specific example, but the configuration can be changed as appropriate.
For example, in the above-described embodiment, the example in which the combination of the fuel cell 12 and the remote control device 11 for setting the fuel cell 12 and operating instructions is used as the equipment 10 of the present invention has been described. A combination of various devices installed remotely and the remote control device 11 can be used as the equipment 10 of the present invention. For example, a combination of an air conditioner (air conditioner) that performs cooling operation, heating operation, and the like and a remote control device 11 that performs setting and operation instructions can be used as the equipment 10 of the present invention. FIG. 3 is a diagram illustrating an example of a display screen of the user communication device T. As shown in the figure, the operating status of the air conditioner as the equipment 10 is shown on the display screen of the user communication device T. Specifically, the user communication device T displays that the air conditioner is currently in operation and the past set temperature transition of the air conditioner. In addition, when the user makes a selection input to the “remote control” button 21, it is possible to shift to a mode for instructing remote control to the air conditioner as the equipment 10.
In addition, a combination of a water heater and a remote control device 11 that performs settings and operation instructions thereof can be used as the equipment 10 of the present invention.
Further, the combination of various devices fixedly installed in the building 3 and the remote control device 11 is not used as the facility device 10, but the facility device 10 is composed of only one device fixedly installed in the building 3. May be configured.

<2>
In the above embodiment, the management server device 2 may transmit the control command information to the utility using device 15 to cause the utility using device 15 to forcibly operate. Forcible operation can be set as appropriate, such as operation of an anti-freezing device as described in the above embodiment, addition water to the bathtub, addition water to the bathtub, boiling water in the hot water storage tank, and the like. Note that it is possible to appropriately set at what timing the management server device 2 forcibly operates the utility using device 15.

For example, when the user has not moved away from the building 3 but has been absent for a long period of time, such as travel, the user has built the utility supply pressure and utility supply amount collected by the information collection unit 16 as described above. There may be no change at all as in the case where the supply plug 18 is closed after leaving the article 3.
However, if the management server device 2 sends the control command information to the utility using device 15 to force the utility using device 15 to perform the forced operation, if the user is simply absent for a long time, the forced operation is not performed. It is considered that there are fluctuations in the utility supply pressure and the utility supply amount collected by the information collecting unit 16 before and after being performed (before and after transmitting the control command information). On the other hand, if the user leaves the building 3 and the supply source plug 18 is closed, it is considered that the utility supply pressure and the utility supply amount collected by the information collecting unit 16 are not changed. In this way, the utility using device 15 cannot be used based on the determination information collected by the information collecting unit 16 before and after the control command information is transmitted to the utility using device 15 and the utility using device 15 is forced to operate. It can be determined whether or not it is in a state.

<3>
Although some examples of apparatus operation information were given in the said embodiment, various information regarding the driving | operation of the equipment 10 which is not described in the said embodiment is employable as apparatus operation information.

<4>
The configuration disclosed in the above embodiment (including another embodiment, the same applies hereinafter) can be applied in combination with the configuration disclosed in the other embodiment as long as no contradiction arises. The embodiment disclosed in the document is an exemplification, and the embodiment of the present invention is not limited to this, and can be appropriately modified without departing from the object of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be used in a device information management system that can realize the disappearance of access authority to a facility device with a simple configuration when the use of the facility device is stopped due to the user leaving or the like.
