Abstract
Description
- This application is a U.S. national stage application of International Patent Application No. PCT/JP2017/013375 filed on Mar. 30, 2017, the disclosure of which is incorporated herein by reference.
- The present invention relates to an air-conditioning control relay device that relays signals sent and received between an air conditioner and a communication terminal device.
- Generally, a decrease in an outdoor temperature to or below a certain temperature reduces the heating capability of an air conditioner, which may result in a failure to provide the heating capability demanded by a user. When the heating capability of an air conditioner is reduced, the user uses a heat source device in addition to the air conditioner. One example of heat source device is a heater. Use of both the air conditioner and the heat source device requires the user to operate the air conditioner and the heat source device individually. Individual operations of the air conditioner and of the heat source device place a burden on the user.
- To avoid a burdensome operation by the user, an information terminal device having control functions has been suggested that enables an on-off operation of each of an air conditioner and a heater each connected to a home automation terminal, based on a signal from a communication network (see, e.g., Patent Literature 1).
- Patent Literature 1: Japanese Patent Application Laid-open No. 2005-204178
- However, in the conventional technology described above, the information terminal device having control functions is connected to the air conditioner and to the heater via home automation terminals. This enables merely simple control to be provided to the air conditioner. One example of the simple control is on-off switching or switching between heating and cooling.

FIG. 1 is a configuration diagram of asystem 10 including an air-conditioningcontrol relay device 1 according to a first embodiment. Thesystem 10 includes, in addition to the air-conditioningcontrol relay device 1, an air conditioner 2, acommunication terminal device 3 for remotely controlling the air conditioner 2, and acontact device 4. The air-conditioningcontrol relay device 1 is communicable with the air conditioner 2, and is communicable also with thecommunication terminal device 3. In more detail, the air-conditioningcontrol relay device 1 is a device that relays signals sent and received between the air conditioner 2 and thecommunication terminal device 3. The air-conditioningcontrol relay device 1 can also operate thecontact device 4. Thecontact device 4 is a device controlled by thecommunication terminal device 3 via the air-conditioningcontrol relay device 1. One example of thecontact device 4 is a heater. - The air-conditioning
control relay device 1 includes afirst communication unit 11 that communicates with thecommunication terminal device 3, and asecond communication unit 12 that communicates with the air conditioner 2. The air-conditioningcontrol relay device 1 further includes ananalysis unit 13 that analyzes both first information received by thefirst communication unit 11 from thecommunication terminal device 3, and second information received by thesecond communication unit 12 from the air conditioner 2. The air-conditioningcontrol relay device 1 further includes anoperation unit 14 that operates thecontact device 4 based on the first information or on the second information in a case in which theanalysis unit 13 determines, by analyzing, that the first information or the second information is information for operating of thecontact device 4. - The
first communication unit 11 sends the first information received from thecommunication terminal device 3 to thesecond communication unit 12 and to theanalysis unit 13. In a case in which thecontact device 4 is to be operated based on an analysis performed by theanalysis unit 13, thefirst communication unit 11 sends operation performing information indicating that thecontact device 4 will be operated, to thecommunication terminal device 3. For example, in a case in which thecontact device 4 is to be operated based on the first information based on an analysis performed by theanalysis unit 13, thefirst communication unit 11 sends operation performing information indicating that thecontact device 4 will be operated based on the first information, to thecommunication terminal device 3. - The
second communication unit 12 sends the first information received from thefirst communication unit 11 to the air conditioner 2, and also sends the second information received from the air conditioner 2 to thefirst communication unit 11 and to theanalysis unit 13. Thefirst communication unit 11 sends the second information received from thesecond communication unit 12 to thecommunication terminal device 3. - The functions of each of the
first communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 included in the air-conditioningcontrol relay device 1 will be described below using a specific example. Thefirst communication unit 11 receives a signal sent from thecommunication terminal device 3 at an arbitrary time on a byte-by-byte basis, and sends one byte of signal to thesecond communication unit 12 upon each reception of one byte of the signal from thecommunication terminal device 3. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the processing by thefirst communication unit 11 of receiving a signal from thecommunication terminal device 3 and of sending the received signal to thesecond communication unit 12 is implemented by a receive interrupt process of that microcomputer. - When the amount of the signal received from the
communication terminal device 3 reaches a predetermined specific amount, thefirst communication unit 11 sends the signal received from thecommunication terminal device 3 to theanalysis unit 13, and requests theanalysis unit 13 to analyze the signal sent. - Upon reception of a signal from the
first communication unit 11, thesecond communication unit 12 sends the signal received, to the air conditioner 2. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the processing by thesecond communication unit 12 of receiving a signal from thefirst communication unit 11 and of sending the received signal to the air conditioner 2 is implemented by a transmission interrupt process of that microcomputer. For example, thefirst communication unit 11 assigns the signal to one particular transmission port of the microcomputer to provide the transmission interrupt process described above. When this is the case, the processing of thesecond communication unit 12 is substituted by the processing performed by thefirst communication unit 11 to assign the signal to the particular transmission port. - The
second communication unit 12 receives a signal sent from the air conditioner 2 at an arbitrary time on a byte-by-byte basis, and sends one byte of signal to thefirst communication unit 11 upon each reception of one byte of the signal from the air conditioner 2. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the processing by thesecond communication unit 12 of receiving a signal from the air conditioner 2 and of sending the received signal to thefirst communication unit 11 is implemented by a receive interrupt process of that microcomputer. - Upon reception of a signal from the
second communication unit 12, thefirst communication unit 11 sends the signal received, to thecommunication terminal device 3. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the processing by thefirst communication unit 11 of receiving a signal from thesecond communication unit 12 and of sending the received signal to thecommunication terminal device 3 is implemented by a transmission interrupt process of that microcomputer. For example, thesecond communication unit 12 assigns the signal to one particular transmission port of the microcomputer to perform the transmission interrupt process described above. When this is the case, the processing of thefirst communication unit 11 is substituted by the processing performed by thesecond communication unit 12 to assign the signal to the one particular transmission port. - When the amount of the signal received from the air conditioner 2 reaches a predetermined specific amount, the
second communication unit 12 sends the signal received from the air conditioner 2 to theanalysis unit 13, and requests theanalysis unit 13 to analyze the signal sent. - Upon a request for analysis from the
first communication unit 11, theanalysis unit 13 analyzes the signal received from thefirst communication unit 11. Upon a request for analysis from thesecond communication unit 12, theanalysis unit 13 analyzes the signal received from thesecond communication unit 12. If it is determined, based on a result of the analysis, that processing is required on a contact of thecontact device 4, theanalysis unit 13 sends, to theoperation unit 14, a signal containing an instruction to perform an operation on the contact of thecontact device 4. - Upon reception of the signal containing an instruction to perform an operation on a contact of the
contact device 4 from theanalysis unit 13, theoperation unit 14 performs an operation on that contact according to the instruction. - One specific example of the operation of the
first communication unit 11 will next be described.FIG. 2 is a flowchart illustrating an example of operation procedure of thefirst communication unit 11 included in the air-conditioningcontrol relay device 1 according to the first embodiment. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the operation procedure of thefirst communication unit 11 may be called out by the receive interrupt function of that microcomputer. The operation of thefirst communication unit 11 may be performed every predetermined period. - The
first communication unit 11 first determines whether a signal has been received from the communication terminal device 3 (S1). At step S1, thefirst communication unit 11 may perform a filtering process of discarding the signal received from thecommunication terminal device 3 if it is determined, by performing error detection using a parity bit, that the signal received from thecommunication terminal device 3 is erroneous. - If it is determined that a signal has been received from the communication terminal device 3 (Yes at S1), the
first communication unit 11 sends the signal received from thecommunication terminal device 3 to the second communication unit 12 (S2). Thesecond communication unit 12 sends the signal received from thefirst communication unit 11 to the air conditioner 2. That is, the signal from thecommunication terminal device 3 is relayed by the air-conditioningcontrol relay device 1, and is thus transmitted to the air conditioner 2. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the processing by thefirst communication unit 11 of receiving the signal from thecommunication terminal device 3 and of sending the received signal to thesecond communication unit 12 may be implemented by assignment of the signal from thecommunication terminal device 3 to one particular transmission port of the microcomputer. - At step S2, the
first communication unit 11 sends, without storing therein, the signal received from thecommunication terminal device 3 to thesecond communication unit 12. This operation can reduce the effects of processing performed by the air-conditioningcontrol relay device 1 on the overall operation of thesystem 10. Specifically, the air-conditioningcontrol relay device 1 relays and sends the signal from thecommunication terminal device 3 to the air conditioner 2, which causes the operation of the air conditioner 2 caused by that signal to be delayed by the amount of time relating to the relay operation performed by the air-conditioningcontrol relay device 1. However, since thefirst communication unit 11 does not store the signal received from thecommunication terminal device 3, the operation of the air conditioner 2 is prevented from being delayed by more than the amount of time relating to the relay operation. - After the performance of the operation at step S2, the
first communication unit 11 determines whether the amount of the signal received from thecommunication terminal device 3 has reached a predetermined specific amount (S3). If it is determined that the amount of the signal received from thecommunication terminal device 3 has reached the predetermined specific amount (Yes at S3), thefirst communication unit 11 sends the signal having the specific amount received from thecommunication terminal device 3 to the analysis unit 13 (S4). In addition, thefirst communication unit 11 requests theanalysis unit 13 to analyze the signal sent. - The
first communication unit 11 may use a value indicated by a signal stored in a particular byte of the signal received from thecommunication terminal device 3, as the predetermined specific amount. In such case, thefirst communication unit 11 sends a signal including the particular byte of the signal received from thecommunication terminal device 3, to theanalysis unit 13. Moreover, thefirst communication unit 11 may perform the operation of step S4 when a certain time period has elapsed since the latest reception time, taking this as an indication of completion of the reception. If it is determined that the amount of the signal received from thecommunication terminal device 3 has not yet reached the predetermined specific amount (No at S3), thefirst communication unit 11 does not perform the operation of step S4, and terminates the process. - If it is determined that no signal has been received from the communication terminal device 3 (No at S1), the
first communication unit 11 determines whether a signal has been received from the second communication unit 12 (S5). If it is determined that a signal has been received from the second communication unit 12 (Yes at S5), thefirst communication unit 11 sends the signal received from thesecond communication unit 12 to the communication terminal device 3 (S6). In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the processing by thefirst communication unit 11 of receiving the signal from thesecond communication unit 12 after thesecond communication unit 12 receives the signal from the air conditioner 2 may be implemented by assignment of the signal from the air conditioner 2 to one particular transmission port of the microcomputer. - If it is not determined that a signal has been received from the second communication unit 12 (No at S5), the
first communication unit 11 terminates the sequence of process after the operation of step S6, and repeats the operation described above from step S1 to step S6. - The
second communication unit 12 operates similarly to the operation of thefirst communication unit 11. Specifically, in one specific example, thesecond communication unit 12 operates as described above using the flowchart illustrated inFIG. 2 except that the term “first communication unit 11” should be read as thesecond communication unit 12, and the term “communication terminal device 3” should be read as the air conditioner 2. - One specific example of the operation of the
analysis unit 13 will next be described.FIG. 3 is a flowchart illustrating an example of operation procedure of theanalysis unit 13 included in the air-conditioningcontrol relay device 1 according to the first embodiment. In a case in which thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 are implemented by a single microcomputer, the operation procedure of theanalysis unit 13 may be called out by the receive interrupt function of that microcomputer. The operation of theanalysis unit 13 may be performed every predetermined period. - The
analysis unit 13 determines whether an analysis of a signal received is requested (S11). If it is determined that an analysis of a signal received is requested (Yes at S11), theanalysis unit 13 analyzes the signal received (S12). Theanalysis unit 13 performs an analysis according to a predetermined algorithm. - The
analysis unit 13 determines, based on a result of the analysis, whether the signal received from thefirst communication unit 11 is a close-contact signal indicating that the contact of thecontact device 4 is to be closed (S13). If it is determined that the signal received is a close-contact signal (Yes at S13), theanalysis unit 13 sends, to theoperation unit 14, an instruction to perform an operation to close the contact of the contact device 4 (S14). Theoperation unit 14 closes the contact according to the instruction from theanalysis unit 13. - If it is determined that the signal received is not a close-contact signal (No at S13), the
analysis unit 13 determines whether the signal received from thefirst communication unit 11 is an open-contact signal indicating that the contact of thecontact device 4 is to be opened (S15). If it is determined that the signal received is an open-contact signal (Yes at S15), theanalysis unit 13 sends, to theoperation unit 14, an instruction to perform an operation to open the contact of the contact device 4 (S16). Theoperation unit 14 opens the contact according to the instruction from theanalysis unit 13. - After the performance of the operation of step S14 or step S16, the
analysis unit 13 sends operation performing information indicating that thecontact device 4 will be operated, to the first communication unit 11 (S17). Upon reception of the operation performing information from theanalysis unit 13, thefirst communication unit 11 sends operation performing information to thecommunication terminal device 3. In a case in which thefirst communication unit 11 and thesecond communication unit 12 are implemented by a single microcomputer, the operation of step S17 is implemented by a transmission interrupt process of that microcomputer. For example, theanalysis unit 13 assigns the signal representing operation performing information to one transmission port of the microcomputer to provide the transmission interrupt process described above. When this is the case, the processing of thefirst communication unit 11 is substituted by the processing performed by theanalysis unit 13 to assign the signal to the transmission port. - If it is determined that an analysis of the signal received is not requested (No at S11), or if it is not determined that the signal received is an open-contact signal (No at S15), the
analysis unit 13 terminates the sequence of process after the operation of step S17, and repeats the operation described above from step S11 to step S17. - The
operation unit 14 opens or closes a contact of thecontact device 4 according to the instruction from theanalysis unit 13. When thesystem 10 includes multiple ones of thecontact device 4, and an instruction to close the contacts of the multiple ones of thecontact device 4 is received from theanalysis unit 13, theoperation unit 14 does not close the contacts of the multiple ones of thecontact device 4 at the same time thereby to prevent an inrush current from flowing. Theoperation unit 14 closes the contacts of the multiple ones of thecontact device 4 one by one sequentially. - As described above, in the air-conditioning
control relay device 1, thefirst communication unit 11 sends the first information received from thecommunication terminal device 3 to thesecond communication unit 12, and thesecond communication unit 12 sends the first information received from thefirst communication unit 11 to the air conditioner 2. In more detail, the air-conditioningcontrol relay device 1 sends the first information received from thecommunication terminal device 3 to the air conditioner 2 without processing. In addition, in the air-conditioningcontrol relay device 1, theanalysis unit 13 analyzes the first information received by thefirst communication unit 11 from thecommunication terminal device 3, and if theanalysis unit 13 determines, based on the analysis, that the first information is information for operating of thecontact device 4, theoperation unit 14 operates thecontact device 4 based on the first information. - Thus, in the
system 10 including the air conditioner 2 and thecommunication terminal device 3 for remotely controlling the air conditioner 2, the air-conditioningcontrol relay device 1 can control the air conditioner 2 without imposing a limitation on the functions of the air conditioner 2, and can also operate thecontact device 4. Specifically, in a case in which thecontact device 4 is a heater, a fan, or a humidifier-dehumidifier, the air-conditioningcontrol relay device 1 can control the air conditioner 2 without imposing a limitation on the functions of the air conditioner 2, and can also operate the heater, the fan, or the humidifier-dehumidifier. - In addition, in the air-conditioning
control relay device 1, thesecond communication unit 12 sends the second information received from the air conditioner 2 to thefirst communication unit 11, and thefirst communication unit 11 sends the second information received from thesecond communication unit 12 to thecommunication terminal device 3. That is, the air-conditioningcontrol relay device 1 can transmit the second information from the air conditioner 2 to thecommunication terminal device 3 without change. - Moreover, in the air-conditioning
control relay device 1, theanalysis unit 13 has a function of analyzing the second information received by thesecond communication unit 12 from the air conditioner 2, and if theanalysis unit 13 determines, by analyzing, that the second information is information for operating thecontact device 4, theoperation unit 14 operates thecontact device 4 based on the second information. That is, the air-conditioningcontrol relay device 1 can operate thecontact device 4 based on the second information from the air conditioner 2. - Furthermore, in the air-conditioning
control relay device 1, thefirst communication unit 11 sends, to thecommunication terminal device 3, the operation performing information indicating that thecontact device 4 will be operated if thecontact device 4 is to be operated based on an analysis performed by theanalysis unit 13. That is, in a case in which thecontact device 4 is to be operated based on the first information or on the second information, the air-conditioningcontrol relay device 1 can inform thecommunication terminal device 3 that thecontact device 4 will be operated. -
FIG. 4 is a diagram illustrating aprocessing circuit 41 in a case in which at least a portion of components including thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 included in the air-conditioningcontrol relay device 1 according to the first embodiment is implemented by theprocessing circuit 41. That is, at least a portion of the functions of thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 may be implemented in theprocessing circuit 41. - The

Theprocessor 51 is a central processing unit (CPU), a processing unit, a computing unit, a microprocessor, a microcomputer, or a digital signal processor (DSP).FIG. 5 also illustrates thememory 52. - In a case in which at least a portion of the functions of the
first communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 is implemented by theprocessor 51, that portion of the functions is implemented by theprocessor 51 and software, firmware, or a combination of software and firmware. The software or firmware is described as a program, and is stored in thememory 52. Theprocessor 51 reads and executes a program stored in thememory 52 thus to implement at least a portion of the functions of thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14. - That is, in a case in which at least a portion of the functions of the
first communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 is implemented by theprocessor 51, the air-conditioningcontrol relay device 1 includes thememory 52 for storing a program that causes the steps performed by that portion of thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 to be resultantly performed. It can also be said that a program stored in thememory 52 causes a computer to perform a procedure or method to be performed by a portion of thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14. - The
memory 52 is, for example, a non-volatile or volatile semiconductor memory such as a random access memory (RAM), a read-only memory (ROM), a flash memory, an erasable programmable read-only memory (EPROM), or an electrically erasable programmable read-only memory (EEPROM); a magnetic disk, a flexible disk, an optical disk, a compact disc, a MiniDisc, a digital versatile disk (DVD), or the like. - Multiple functions of the
first communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 may be provided such that a portion of the multiple functions is implemented by dedicated hardware, and the remainder of the multiple functions is implemented by software or firmware. Thus, multiple functions of thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 can be implemented by hardware, software, firmware, or a combination thereof. -
FIG. 6 is a configuration diagram of asystem 10A including an air-conditioningcontrol relay device 1A according to a second embodiment. Thesystem 10A includes, in addition to the air-conditioningcontrol relay device 1A, the air conditioner 2, thecommunication terminal device 3, thecontact device 4, and asensor 5 disposed outside the air-conditioningcontrol relay device 1A. The air conditioner 2, thecommunication terminal device 3, and thecontact device 4 have already been described in the first embodiment, and a description thereof will thus be omitted in the second embodiment. The second embodiment primarily describes differences from the first embodiment. - One example of the
sensor 5 is a temperature sensor that detects the temperature outside the building where the air conditioner 2 is installed, a human detection sensor, or a gas sensor. The air-conditioningcontrol relay device 1A includes thefirst communication unit 11, thesecond communication unit 12, theanalysis unit 13, and theoperation unit 14 included in the air-conditioningcontrol relay device 1 according to the first embodiment, and further includes athird communication unit 15 that receives third information with respect to a value detected by thesensor 5. In more detail, thesensor 5 sends the third information to thethird communication unit 15, and thethird communication unit 15 receives the third information from thesensor 5. - In a case in which the
first communication unit 11, thesecond communication unit 12, theanalysis unit 13, theoperation unit 14, and thethird communication unit 15 are implemented by a single microcomputer, and thesensor 5 is a variable resistor, the third information may be received into the microcomputer through an analog-digital port of the microcomputer. - The
third communication unit 15 sends the third information received from thesensor 5 to theanalysis unit 13. If it is determined, based on a result of an analysis, that the first information received from thefirst communication unit 11 indicates a request for sending the third information to thefirst communication unit 11, theanalysis unit 13 sends the third information received from thethird communication unit 15 to thefirst communication unit 11. If it is determined, based on a result of an analysis, that the second information received from thesecond communication unit 12 indicates a request for sending the third information to thefirst communication unit 11, theanalysis unit 13 also sends the third information received from thethird communication unit 15 to thefirst communication unit 11.

Thesecond communication unit 12 receives the third information sent from theanalysis unit 13, and sends the third information to the air conditioner 2. - As described above, the air-conditioning
control relay device 1A sends the third information from thesensor 5 to one or both of the air conditioner 2 and thecommunication terminal device 3 without affecting the communication between the air conditioner 2 and thecommunication terminal device 3. That is, the air-conditioningcontrol relay device 1A enables thesystem 10 according to the first embodiment to include thesensor 5 without affecting the communication between the air conditioner 2 and thecommunication terminal device 3. - At least a portion of the functions of the
third communication unit 15 may be implemented by theprocessing circuit 41, or may be implemented by a processing circuit having functions identical to the functions of theprocessing circuit 41. Alternatively, at least a portion of the functions of thethird communication unit 15 may be implemented by theprocessor 51, or may be implemented by a processor different from theprocessor 51. In a case in which at least a portion of the functions of thethird communication unit 15 is implemented by theprocessor 51, thememory 52 stores a program that causes the steps resultantly performed by the at least a portion of thethird communication unit 15 to be performed.
