Description

  The present invention relates to a communication adapter device, and more particularly to a communication adapter device for communication-connecting a household energy management system and a heat source device such as a hot water supply device.

  In recent years, the amount of power used and the operating state of electrical equipment (for example, lighting equipment and air conditioners) in the homes of power consumers can be visualized (so-called visualization) using a control device such as a personal computer, smartphone or tablet terminal, or A home energy management system (HEMS) that is remotely operated has been proposed.

  This home energy management system connects electrical equipment in a customer's home and a HEMS controller (control device) via a computer network such as a LAN (Local Area Network) and performs communication between the controller and the electrical equipment. The HEMS controller displays the amount of electric power used and the operating state of the electric equipment, and the HEMS controller is used to control the electric equipment (for example, switching on / off of lighting equipment, switching on / off of the air conditioner, Furthermore, the air conditioning set temperature of the air conditioner can be changed (for example, see Patent Document 1).

  Here, communication is performed between a controller and electrical equipment in such a HEMS in accordance with a predetermined standardized communication standard (for example, “ECHONET Lite” formulated by the Echonet Consortium), and the HEMS controller is standardized. It is designed to communicate with electrical equipment that complies with the established communication standards.

  On the other hand, a heat source device such as a hot water supply device communicates with a remote control device that is a remote control device or a hot water terminal device (for example, a floor heating panel or a bathroom heating device) that receives hot water supply from the heat source device. However, at present, the communication between the heat source device and these terminal devices all follow a dedicated communication standard and does not correspond to the HEMS communication standard.

JP 2013-20488 A

  By the way, with the spread of HEMS, there is an increasing demand for visualization and control of power usage of heat source equipment and hot water terminal devices using a HEMS controller, and communication connection between the heat source equipment and HEMS. Although development of a communication adapter device for carrying out the above is underway, communication connection between the HEMS and the heat source device has the following problems.

  That is, when the operation state of the hot water terminal apparatus is changed using the HEMS controller, first, an operation state change request is made from the HEMS controller to the heat source unit. Based on this change request, the communication adapter device instructs the heat source device (the hot water terminal device specified via the heat source device) to change the operating state of the hot water terminal device (hereinafter referred to as “SET communication”). However, when the operation state of the hot water terminal device cannot be changed due to an abnormality in the SET communication, it takes time until the operation state of the hot water terminal device stored in the communication adapter device is changed. Therefore, there is a problem that the actual state of the hot water terminal device and the state of the hot water terminal device displayed on the controller of the HEMS are inconsistent for a long time.

  FIG. 6 shows a case where there is an abnormality in SET communication from the communication adapter device to the heat source device when the operation state of the hot water terminal device is changed from operation off to operation on. As shown in FIG. 6, when the HEMS controller makes an operation state change request to the communication adapter device, if there is a response indicating that the request has been received from the communication adapter device, the operation of the hot water terminal device on the HEMS controller is performed. The state is updated from driving off to driving on.

  On the other hand, the communication adapter device that has received the operation state change request from the HEMS controller performs SET communication (SET communication for changing the hot water terminal device from operation OFF to operation ON) to the heat source device, but this SET communication fails. Even if it exists, the driving | running state of the hot water terminal device memorize | stored in a communication adapter apparatus will be updated from driving | running off to driving | operation on.

  At this time, since the heat source device has not received the SET communication from the communication adapter device, the operation state of the hot water terminal device stored in the heat source device remains unchanged and the operation remains off. The SET communication for the terminal device is not performed, and the operation state of the hot water terminal device remains unchanged and remains unchanged. That is, here, a mismatch (mismatch) occurs between the display on the HEMS controller and the actual operation state of the hot water terminal device.

  On the other hand, the HEMS controller periodically makes an operation state acquisition request for all the hot water terminal devices to the communication adapter device. At the time of issuing this acquisition request, the display on the HEMS controller and the hot water terminal device. The actual operating state remains inconsistent.

  The communication adapter device that has received the operation state acquisition request from the HEMS controller instructs the heat source device (the hot water terminal device specified via the heat source device) to acquire the operation state of the hot water terminal device (hereinafter, referred to as “state acquisition communication”). In this case, if the GET communication between the communication adapter device and the heat source unit is successful, the operation state of the hot water terminal device stored in the communication adapter device is Updated from driving on to driving off. That is, the operation state of the hot water terminal device stored in the communication adapter device at this time is matched (matched) with the actual operation state of the hot water terminal device, and then the display on the HEMS controller and the actual operation of the hot water terminal device are performed. The operating state of the system becomes consistent.

  Therefore, if it takes time for GET communication to be performed periodically after a mismatch between the display on the HEMS controller and the actual operation state of the hot water terminal device occurs, the display on the HEMS controller and the actual operation of the hot water terminal device There is a problem that the state that does not match the state is prolonged.

  The present invention has been made in view of such conventional problems, and the object of the present invention is to disagree between the actual state of the hot water terminal device and the display of the operating state of the hot water terminal device in the HEMS controller. An object of the present invention is to provide a communication adapter device that can shorten the time.

  In order to achieve the above object, a communication adapter device according to claim 1 of the present invention is a control device that performs information collection and / or remote operation of an electric device in a customer's home via a computer network.

Control means having a control unit, and the control means operates the second terminal device connected to the heat source device via the communication means according to the first communication standard. In addition to performing status acquisition communication for sequentially acquiring status data for each terminal device at regular time intervals, based on a request from the control device, any one of the second terminals via communication means according to the first communication standard When the state setting communication commanding the change of the operation state of the device is performed, a control configuration is provided for performing the collective state acquisition communication for simultaneously acquiring the operation state data of all the second terminal devices. It is characterized by.

  In the communication adapter device according to claim 1, after the communication adapter device performs state setting communication (SET communication) instructing the change of the operation state of any of the second terminal devices, the operation states of all the second terminal devices. Since collective state acquisition communication for acquiring data in a batch is performed, the operation state of the hot water terminal device stored in the communication adapter device is updated in accordance with the change in the operation state of the hot water terminal device. For this reason, the time during which a mismatch occurs between the operating state of the hot water terminal device stored in the communication adapter device and the actual state of the hot water terminal device is shortened.

  The communication adapter device according to claim 2 of the present invention is the communication adapter device according to claim 1, wherein the collective state acquisition communication is performed after a predetermined time has elapsed since the occurrence of the state setting communication. The predetermined time is set to be equal to or less than the predetermined time.

  In the communication adapter device according to claim 2, the timing for performing the collective state acquisition communication after the SET communication is set to be equal to or less than the interval (the above-described fixed time) when the communication adapter device sequentially acquires the operation state data for each terminal device. Therefore, the operation state data of the hot water terminal device is acquired at the same timing or earlier than the GET communication performed by one terminal device every fixed time, and the operation of the hot water terminal device stored in the communication adapter device The mismatch time between the state and the actual state of the hot water terminal device can be reliably shortened.

  According to a third aspect of the present invention, in the communication adapter device according to the first or second aspect, the batch state acquisition communication is configured to be executed with priority over the state acquisition communication. It is characterized by.

  In the communication adapter device according to the third aspect, since the collective state acquisition communication after the SET communication is preferentially executed over the state acquisition communication, GET is performed on the hot water terminal devices other than the hot water terminal device whose operation state has been changed. Even when the timing for performing communication is reached, the operating state of the hot water terminal apparatus that has performed SET communication can be preferentially acquired, and inconsistencies can be quickly resolved.

  According to the present invention, the communication adapter device performs batch state acquisition communication for collectively acquiring the operation state data of all the second terminal devices after performing SET communication, so the hot water terminal device stored in the communication adapter device It is possible to reduce the time for the occurrence of inconsistency between the operation state of the battery and the actual state of the hot water terminal device, and to reduce the inconsistency time between the display on the HEMS controller and the actual state of the hot water terminal device. be able to.

The terminal device 4 is configured to be remotely operated.

  First, the hot water supply device 3 will be described. The hot water supply device 3 has a well-known hot water supply function for supplying hot water to a hot water tap (not shown), a bath function for reheating the bath, and a hot water heating function for supplying hot water serving as a heat medium to the hot water terminal device 4.

  Here, in the illustrated example, as the remote controller 5, three remote controllers 5 including a bathroom remote controller 5a installed in the bathroom, a kitchen remote controller 5b installed in the kitchen, and a sub-remote controller 5c installed in a place other than the bathroom and the kitchen are illustrated. As shown, at least one remote controller 5 may be used, and the number of remote controllers 5 can be changed as appropriate.

  In the illustrated example, eight hot water terminal devices 4 of 4a to 4h are illustrated as the hot water terminal devices 4, but this is the maximum number of connections of the hot water terminal devices 4 that can be controlled by the HEMS controller 2 (this embodiment). The number of connected hot water terminal devices 4 is eight or less, and can be changed as appropriate. As the hot water terminal device 4, there are various devices such as a floor heating panel, a panel heater, a fan convector, a bathroom dryer, a bathroom heater / dryer, a mist sauna, and the combination depends on the construction site of the hot water supply device 3. The selection can be changed as appropriate.

  Furthermore, in the illustrated example, the power measurement unit 6 is illustrated as an optional device of the hot water supply device 3, but this is the power consumption (electric power consumption) in the electrical equipment in the customer's home including the hot water supply device 3 and the hot water terminal device 4. ) Is a unit equipped with a sensor or the like. In addition, as an optional device of the hot water supply device 3, a device other than the power measurement unit 6 (for example, an automatic drain plug of a bathtub) may be connected.

  And in the hot water supply apparatus 3 comprised in this way, while the remote control 5 and the electric power measurement unit 6 are connected with the hot water supply apparatus 3 by the communication line L1, the hot water terminal device 4 is connected with the hot water supply apparatus 3 by the communication line L2. . Here, different communication standards are adopted for the communication line L1 and the communication line L2.

  Specifically, the communication line L1 is connected according to a unique communication standard (first communication standard) established by the manufacturer of the hot water supply device 3, and the communication line L2 is a communication standard (standardized by a gas company) ( Connected by the second communication standard). More specifically, the communication standard of the communication line L1 is a power superimposition communication method in which power is supplied from the hot water supply device 3 to the terminal devices (the remote controller 5 and the power measurement unit 6) connected to the communication line L1. A communication standard is adopted, and TES (Thin & Economical System) is adopted as the communication standard of the communication line L2. In the present invention, the terminal device connected by the communication line L1 (that is, the first communication standard) is the first terminal device, and the terminal device connected by the communication line L2 (that is, the second communication standard) is the second terminal. Configure the device.

  And the hot water supply apparatus 3 to which the communication line L1 and the communication line L2 are connected in this way communicates with the remote controller 5, the power measuring unit 6, and further the hot water terminal apparatus 4 via these communication lines L1 and L2. A control unit (not shown) is provided, and each part of the hot water supply device 3 is controlled by the control unit of the hot water supply device 3. That is, the control unit of the hot water supply device 3 is configured to cause the hot water supply device 3 to perform operations corresponding to the hot water supply function, the bath reheating function, and the hot water heating function in accordance with the operation of the remote controller 5 or the like. .

  The connection between the hot water supply device 3 and the hot water terminal device 4 is configured to connect the communication line L2 from the hot water terminal device 4 to a predetermined connection terminal (not shown) provided in the hot water supply device 3. The controller of the hot water supply device 3 can grasp how many hot water terminal devices 4 are connected from the connection status to the connection terminals. In the present embodiment, since up to eight hot water terminal devices 4 can be connected to the hot water supply device 3, eight connection terminals are provided.

  On the other hand, the HEMS controller 2 includes a predetermined display unit such as a personal computer, a smartphone, or a tablet terminal, and can execute a control program of the HEMS (in other words, obtains and displays information on an electrical device connected to the HEMS, and (Or remote control of electrical equipment connected to the HEMS). In the present embodiment, a tablet terminal (a plate-like all-in-one computer) compatible with a wireless LAN (Local Area Network) is used as the HEMS controller 2.

  The router 7 is a communication relay device for connecting the HEMS controller 2 and a HEMS compatible electrical device in a customer's home via a computer network such as a LAN. The router 7 is connected to the HEMS controller 2 by a wireless LAN and a communication adapter. The device 1 is connected by wire via a communication line L3. Here, Ethernet (registered trademark) generally used as a computer network is used for the communication line L3. In this communication line L3, a predetermined communication standard (for example, Echonet Consortium) standardized for HEMS is used. The communication adapter device 1 and the HEMS controller 2 are connected for communication by “ECHONET Lite”). Note that the communication standard used in the communication line L3 is different from the first communication standard and the second communication standard described above.

  The communication adapter device 1 can perform information acquisition of the hot water terminal device 4 by the HEMS controller 2 and / or remote operation of the hot water terminal device 4 by the HEMS controller 2 by communicatively connecting the hot water supply device 3 and the HEMS controller 2. As shown in FIG. 2, a network adapter 10 (which constitutes a communication means with a computer network) that communicates via a communication line L3 and a communication line L1 Superimposition communication unit 11 that communicates with hot water supply device 3 (which is a communication unit according to the first communication standard), and control unit (control unit) 12 that relays communication between network communication unit 10 and superimposition communication unit 11 And as a main part.

  Specifically, the control unit 12 includes a microcomputer as a control center, and is configured to be able to exchange commands (commands) and data with the HEMS controller 2 via the network communication unit 10. 11 is configured so that commands and data can be exchanged with the hot water supply device 3 (or the hot water terminal device 4 via the hot water supply device 3) via 11 (details will be described later). The control unit 12 includes a clock generation circuit (not shown), and the control unit 12 can measure time based on a clock signal from the clock generation circuit.

  The power supply unit 13 is a power supply device that receives DC power supplied from the hot water supply device 3 via the communication line L <b> 1 and supplies driving power to each unit of the communication adapter device 1. The storage unit 14 is a volatile memory that appropriately stores data when the control unit 12 processes data. And in this embodiment, this memory | storage part 14 comprises the memory area which memorize | stores the operation state data of the hot water terminal device 4 mentioned later. The storage unit 14 may be replaced by a RAM provided in the microcomputer.

Next, the operation of the communication adapter device 1 configured as described above will be described.
In this communication adapter device 1, when there is a request for changing the operation state of the hot water terminal device 4 (operation state change request) from the HEMS controller 2 communicatively connected via the router 7, the control unit 12 responds to the change request. The hot water terminal device 4 to be specified is designated, and SET communication for setting the operation state of the hot water terminal device 4 is performed with respect to the hot water supply device 3. Here, the operation state changed by the SET communication includes, for example, operation on / off switching of the hot water terminal device 4 and change of the heating set temperature.

  On the other hand, acquisition of the operation state data of the hot water terminal device 4 by the communication adapter device 1, that is, GET communication is periodically performed by the control unit 12 of the communication adapter device 1 according to the following procedure, and the HEMS controller 2 performs communication periodically. An acquisition request for the operation state data of the hot water terminal device 4 stored in the storage unit 14 of the adapter device 1 is made to update the information in the HEMS controller 2 in a timely manner.

  FIG. 3 shows an example of this GET communication method. As shown in FIG. 3, the control unit 12 of the communication adapter apparatus 1 sequentially synchronizes with the time every predetermined time (30 seconds in the illustrated example) T1. The operation state data of the hot water terminal device 4 is obtained one by one.

  Here, the fixed time T1 is set based on the required time T2 required to acquire the operation state data from one hot water terminal device 4. Specifically, the fixed time T1 is set to a time longer than the required time T2. In this embodiment, since it takes about 15 seconds to acquire the operation state data from one hot water terminal device 4, it is set to 30 seconds with a little margin. In addition, if this fixed time T1 is set too long with respect to the said required time T2, as shown in FIG. 3, when eight hot water terminal devices 4 are connected, which is the maximum number of connections, each hot water terminal device 4 Since the update cycle of the operation state data becomes long, it is preferable to set so that the update cycle is not so long.

  As described above, in the communication adapter device 1 of the present embodiment, during the GET communication, the control unit 12 of the communication adapter device 1 sequentially operates the operation state data of the hot water terminal device 4 one terminal at a certain time T1 in synchronization with the time. Therefore, the traffic associated with GET communication is leveled. Therefore, it is possible to suppress the possibility that the communication of the remote controller 5 or the like that performs communication according to the first communication standard with the connection of the communication adapter device 1 is delayed.

  And when the communication adapter apparatus 1 shown in this embodiment performs the SET communication mentioned above, after that, it carries out the collective state acquisition communication which acquires the operation state data of all the hot water terminal devices 4 collectively. It is configured. Here, when the operation state of the hot water terminal device 4 is not changed as requested by the SET communication, such as when the collective state acquisition communication fails in the SET communication, the hot water terminal device 4 stored in the communication adapter device 1 is stored. It is the process performed in order to match | combine the state of this with the state of the actual hot water terminal device 4 at an early stage.

This process will be described with reference to FIGS.
FIG. 4 shows a case where there is an abnormality in SET communication from the communication adapter device 1 to the hot water supply device 3 when the operation state of the hot water terminal device 1 is changed from operation off to operation on. As shown in FIG. 4, when the HEMS controller 2 designates the hot water terminal device 4 and the operation state is changed from off to on, the HEMS controller 2 is designated to the communication adapter device 1. When the operation state change request for changing the operation state of the hot water terminal device 4 from OFF to ON is made and a response from the communication adapter device 1 to the request is received, the operation of the hot water terminal device 4 on the HEMS controller is performed. The state is updated from driving off to driving on.

  On the other hand, the communication adapter device 1 that has received the operation state change request from the HEMS controller 2 performs the SET communication corresponding to this request (SET communication for changing the hot water terminal device 4 from operation OFF to operation ON). To do. Here, when this SET communication fails, since the hot water supply device 3 has not received the SET communication from the communication adapter device 1, the operation state of the hot water terminal device 4 stored in the hot water supply device 3 is not changed ( SET communication from the hot water supply device 3 to the hot water terminal device 4 is not performed. That is, the operation state of the designated hot water terminal device 4 remains unchanged and remains unchanged.

  However, even if the SET communication fails, the operation state of the hot water terminal device 4 stored in the communication adapter device 1 is updated from operation off to operation on. Therefore, at this time, the hot water stored in the communication adapter device 1 is stored. Inconsistency occurs between the operation state data of the terminal device 4 and the actual operation state of the hot water terminal device 4.

  Therefore, as shown in FIG. 4, the communication adapter device 1 shown in the present embodiment has the operation state data of all the hot water terminal devices 4 when a predetermined time (for example, 15 seconds) T3 has elapsed since the SET communication was performed. Are configured to perform collective status acquisition communication for acquiring the batches. FIG. 5 shows a state of this collective state acquisition communication. As shown in FIG. 5, in the GET communication that is periodically performed, the hot water terminal devices 4 are sequentially spaced at regular intervals of time T1. Acquisition of the operation state data of the hot water terminal device 4 that has been performed is performed continuously in a continuous manner without any interval (see “all hot water terminal GET communication” in FIG. 4).

  By this collective state acquisition communication, the communication adapter device 1 acquires that the operation state of the hot water terminal device 4 whose operation state has not been changed to operation ON due to failure of the SET communication is operation OFF. The fact (the fact that the hot water terminal device 4 is off) is updated.

  Here, the predetermined time T3 is set to be equal to or less than the predetermined time T1 so as not to exceed an interval (the predetermined time T1) when the operation state data of the hot water terminal device 4 is acquired one by one in regular GET communication. Is done. Specifically, in the present embodiment, the predetermined time T3 is set to a length within the range of T2 <T3 ≦ T1. This is because if the predetermined time T3 is set longer than the predetermined time T1, the update (correction) of the operation state data stored in the communication adapter device 1 may be delayed from the update by the regular GET communication.

  In addition, this collective state acquisition communication is preferentially executed over GET communication that is performed periodically, and when a predetermined time T3 elapses from SET communication even when the execution timing of GET communication arrives, The communication adapter device 1 interrupts and performs batch status acquisition communication.

  Thus, in the communication adapter apparatus 1 shown in this embodiment, since the communication adapter apparatus 1 performs SET communication, the collective state acquisition communication for acquiring the operation state data of all the hot water terminal apparatuses 4 at once is performed. The time during which a mismatch occurs between the operating state of the hot water terminal device 4 stored in the communication adapter device 1 and the actual state of the hot water terminal device can be shortened, and the display on the HEMS controller 2 and the hot water terminal device 4 can be reduced. The inconsistency time with the actual state of is reduced.

  The above-described embodiment shows a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope of the invention.

  For example, in the above-described embodiment, the case where the hot water supply device 3 has a hot water supply function, a bath function, and a hot water heating function has been shown. However, the communication adapter device 1 according to the present invention is a heat source machine that has a hot water heating function. Even a hot water supply device that does not have a function is applicable.

  Moreover, in embodiment mentioned above, although the communication adapter apparatus 1 showed the structure which memorize | stores the driving | running state data of the hot water terminal device 4, it is comprised so that the driving | running state data of the hot water supply apparatus 3 may also be memorize | stored with the hot water terminal device 4. Of course, it is also possible.

  In the above-described embodiment, the case where the HEMS controller 2 is connected to the router 7 in the customer's home by wireless LAN is shown. However, the HEMS controller 2 is connected to the router 7 via an external network such as the Internet 8. It may be configured. Further, when the HEMS controller 2 is connected to the Internet 8, it may be connected to an external server (HEMS cloud) 9 via the Internet 8.
