Description

The present invention relates to various types of management such as monitoring and control of various heat source equipment, terminals or other various equipment that constitutes a hot water heating / cooling system. The present invention relates to a relay adapter used, a remote management system, a remote management method, and a remote management program.

  Conventionally, in a hot water heating / cooling system, a heat source machine that creates hot water using the combustion heat of fuel such as gas and kerosene, electric heat, etc. as a heat source has been installed. Each terminal and the heat source device are controlled in a desired manner by wired or wireless bidirectional communication.

  Such a hot water heating / cooling system is individually installed in a house and constitutes a complete system that is disconnected from the outside. Even a system installed in an apartment house such as an apartment is a complete system in the apartment house. For this reason, even if a remote controller is used for the operation of the hot water heating / cooling system, for example, operations such as floor heating and a fully automatic bath are limited to the residence.

  Moreover, even if the user feels a problem with the system or the equipment, it is not always possible to immediately recognize whether or not it is a failure. For example, even a minor trouble that returns to normal operation due to a power reset etc., or a situation that can not be said to be a failure, a repairman's business trip may be requested, provided by a user who felt a malfunction There are many cases where the information is inaccurate, and there is a problem that an accurate response cannot be made even if a repairman rushes. It is rare that the user's failure recognition, the failure information provided, and the repairer's recognition match, and there is no information recognition match between the user's request and the repairer's response. That is a problem such as delayed response. That is, it is a request for quick repair and a problem of response.

  FIG. 4 shows the main routine of the remote management method and remote management program according to the embodiment of the present invention. In this main routine, it is determined whether or not the repair mode is set in step S1. If the repair mode is set, the process proceeds to step S2 and, for example, processing of the repair mode of the heat source unit 3 is executed. When it is not the repair mode at step S1 or when the processing of the repair mode is completed at step S2, the process proceeds to step S3, where it is determined whether or not data transmission is performed. Execute the process.

  If the data transmission is not performed in step S3 or if the data transmission process is completed in step S4, the process proceeds to step S5, where it is determined whether or not the operation is a remote operation. Execute. If the remote operation is not performed in step S5 or the remote operation processing is completed in step S6, the process proceeds to step S7 to determine whether or not the error is transmitted. If the error is transmitted, the process proceeds to step S8 and the error is transmitted. Execute the process.

  If it is not an error transmission in step S7, or if the error transmission process is completed in step S8, the process proceeds to step S9 to determine whether it is a communication confirmation display. If it is a communication confirmation display, the process proceeds to step S10. To execute the communication confirmation display process. If the communication confirmation display is not performed in step S9 or the communication confirmation display process is completed in step S10, the process proceeds to step S11 to determine whether or not an error code is issued. If there is, the process proceeds to step S12 to execute an error code calling process. If the error code is not called in step S11, or if the error code calling process is completed in step S12, step The process proceeds to S13, where it is determined whether or not the process is another process.

   (9) Heat source machine repair mode

  When repairing a heat source machine, in order to confirm the reproducibility of the trouble under repair, the same error code as the trouble event may be generated several times in a short time. If the error code is transmitted to the management center 30 each time such an error code is generated, the communication cost increases, and the management center 30 recognizes that a new problem occurs each time the error code is generated. Can be confusing. In order to avoid such inconvenience, control that does not transmit an error code to the management center 30 at the time of repair is executed, for example, according to the flowchart shown in FIG.

  FIG. 5 shows an example of this control method and processing program.

  In step S201, it is determined whether or not the operation button 94 of the relay adapter 28 has been operated. In this case, when the operation button 94 is continuously pressed, the microcomputer 66 recognizes the continuous pressing of the operation button 94 through the operation circuit 93 according to the continuous pressing time, and shifts to the communication cut-off state.

  If it is determined in step S201 that the communication interruption operation has been performed by continuously pressing the operation button 94, the process proceeds to step S202, for example, the LED indicators 98 and 100 are alternately blinked, and the communication interruption state is entered. Display. In this case, the display 22 provided in the control device 16 on the heat source unit 3 side displays that the relay adapter 28 has been instructed to disconnect communication, that is, that communication is being interrupted, and visually notifies the repair person.

  As shown in step S203, when the repair on the heat source device 3 side is completed, the process proceeds to step S204, where it is determined whether or not there is a communication return operation by pressing the operation button 94. Steps S202 and S203 are repeated, and the LED indicators 98 and 100 are alternately blinked until the communication return operation is performed, and the communication cutoff state is displayed on the indicator 22.

  When it is recognized in step S204 that the communication return operation has been performed, the process proceeds to step S205, the fact that the communication operation has been performed is displayed on the LED displays 98 and 100, and the display on the display 22 is stopped. . In this case, the LED indicators 98 and 100, for example, display and notify the transition to normal communication by continuously lighting both. Then, the process proceeds to step S206, shifts to normal communication, and returns to the main routine. In addition, when displaying whether it is normal communication or an abnormal state with the LED indicators 98 and 100, you may make it display by changing luminescent color.

  If it is not determined in step S201 that the operation button 94 is continuously pressed, the process proceeds to step S207, where the repair of the device is started, for example, the I / F device 24 is connected through the connector of the control device 16 of the heat source unit 3. Then, the control device 16 of the heat source device 3 shifts to the repair mode. At this time, in order to recognize the repair mode, a repair flag indicating that the repair is being performed is transmitted from the portable terminal 26 through the I / F device 24 to the control device 16. At this time, a similar repair flag is also transmitted from the control device 16 to the relay adapter 28. In the portable terminal 26 having an information processing function, a repair support system is executed that refers to the internal information of the heat source unit 3 or operates specific parts on the heat source unit 3 side to identify a failure location.

  In step S208, the transmission stop state of maintenance information such as an error code to the management center 30 is maintained during communication interruption that continues to transmit the repair flag. As described above, the communication is stopped by the command by continuously pressing the operation button 94 and the repair flag transmitted from the control device 16, and the reliability of the communication stop is improved.

  In step S209, upon completion of the repair of the heat source unit 3, transmission of the repair flag indicating that the heat source unit 3 side is repairing is stopped from the control device 16 on the heat source unit 3 side. At this time, the microcomputer 66 cancels the transmission stop state and proceeds to step S206. In step S206, the microcomputer 66 shifts the communication circuit 74 to the normal communication state and then returns to the main routine.

  (10) Data transmission processing to the management center

  Data transmission / reception between the management center 30 and the relay adapter 28 is executed in response to a request from the management center 30 as shown in FIG. 6, for example. FIG. 6 shows an example of a method for controlling a data transmission mode to the management center 30 and a processing program.

  In step S401, the management center 30 requests real-time information, that is, real-time data, integration system data, invariant data, and an operation mode to the relay adapter 28. In response to this request, in step S402, the data stored in the RAM 72 or the EEPROM 90, which is the storage means of the relay adapter 28, is transmitted to the management center 30, and after the transmission is completed, the process returns to the main routine.

  As described above, data is transmitted from the relay adapter 28 in response to a data request from the management center 30, so that data leakage can be prevented.

  (11) Remote operation processing from the management center

  The remote operation such as the operation of the heat source unit 3, the HA terminal 32, and the commercial power supply device 34 on the relay adapter 28 side by the management center 30 is performed, for example, as shown in FIG. 7, setting the operation mode of the management center 30 and the relay adapter 28. Based on. FIG. 7 shows an example of a remote operation processing control method and processing program from the management center 30.

  In step S601, the operation mode of the heat source device 3, the HA terminal 32, or the commercial power supply device 34 is set from the management center 30 to the relay adapter 28. Based on the setting of the operation mode, in step S602, the relay adapter 28 sets the operation mode of the heat source device 3, the HA terminal 32, or the commercial power supply device 34, and returns to the main routine after setting the operation mode.

  As described above, setting of the operation mode to the relay adapter 28 by the management center 30 and setting of the operation mode of various devices such as the heat source unit 3 in response to the setting by the relay adapter 28, the mode setting is simplified and the setting accuracy is set. Can be increased.

  (12) Error transmission processing when a relay adapter fails

  If a failure occurs in the relay adapter 28, normal processing cannot be executed, and it is necessary to perform quick error processing. Such processing is performed based on error transmission processing on the relay adapter 28 side, for example, as shown in FIG. FIG. 8 shows an example of a control method and processing program for the processing on the relay adapter 28 side and the error transmission processing to the management center 30.

  In step S801, if a failure occurs in the relay adapter 28, the relay adapter 28 generates an error code. In response to the generation of the error code, in step S802, the error code is stored in the EEPROM 90, and time stamp information is added to the error code as time information in order to clarify when the error code has occurred.

  In step S 803, the error code is transmitted from the relay adapter 28 to the management center 30. By receiving this error code, the management center 30 can know the failure of the relay adapter 28 and when the failure has occurred.

  Thus, the relay adapter 28 stores the error code indicating the occurrence of the failure in the EEPROM 90 together with the time information and transmits it to the management center 30, so that the occurrence of the failure can be quickly known on the management center 30 side, Since the code is voluntarily transmitted from the relay adapter 28 side to the management center 30 side, the management center 30 side can quickly recognize the failure of the relay adapter 28 and take appropriate measures.

  (13) Communication confirmation display process during installation

  The relay adapter 28 is installed at the same time as the heat source unit 3. In this case, the central transmission board 38 and the telephone line on the upper side are drawn back and forth with the relay adapter 28 in signal transmission. The central transmission board 38 and the telephone line are expected to be pulled in after the relay adapter 28 is installed. In such an installation situation, if there is an abnormality in the relay adapter 28 or an abnormality between the heat source unit 3 or the relay adapter 28, it is impossible to determine whether or not there is an abnormality at the time of installation. Further, even if a communication failure occurs, it is possible to distinguish between the cause of the abnormality between the heat source unit 3 and the relay adapter 28 and the abnormality between the relay adapter 28 and the centralized transmission panel 38. Required by sex.

  Therefore, the relay adapter 28 is equipped with a determination processing program for determining whether communication between the heat source device 3 and the relay adapter 28 is possible and whether communication between the relay adapter 28 and the centralized transmission panel 38 is possible. LED indicators 98 and 100 are installed as means for displaying the determination result. For example, as shown in FIG. 9, whether or not the communication is normal is displayed in a lighting form. FIG. 9 shows an example of a control method and processing program for communication confirmation display processing.

  In the installation of the heat source unit 3 or the relay adapter 28, or both of them, in step S101, the LED display 98 is turned on and the LED display 100 is turned off, so that the communication between the heat source unit 3 and the relay adapter 28 is normal. Is displayed. That is, the LED display 98 is for communication confirmation between the heat source unit 3 and the relay adapter 28, and the LED display 100 is for communication confirmation between the relay adapter 28 and the central transmission board 38.

  When the installation of the central transmission board 38 and the pull-in of the telephone line are completed as in step S102, the process proceeds to step S103. In step S103, both the LED indicators 98 and 100 are lit, thereby displaying that the communication between the heat source unit 3 and the management center 30 is normal.

  Therefore, in step S104, it is determined whether either of the LED display 98 or the LED display 100 is turned off. If any of the LED displays 98 is turned off, the process proceeds to step S105 and is turned off. It is determined whether or not the LED display 98. When the LED display 98 is turned off, an abnormality between the heat source unit 3 and the relay adapter 28 is displayed as shown in step S106, and when the LED display 100 is turned off, step S106 is performed. As shown in S107, the abnormality between the relay adapter 28 and the concentrated transmission board 38 is displayed, and after returning to the information, the process returns to the main routine.

  As such display means, for example, whether or not the communication between the heat source unit 3 and the relay adapter 28 is normal as a communication path by displaying whether the two LED indicators 98 and 100 are turned on or off, the relay adapters 28 to Since it is displayed whether or not communication between the centralized transmission panels 38 is possible, the operator can instantly grasp whether it is normal or abnormal, can take necessary measures, and perform reliable and quick construction. Can do.

  (14) Error code call processing

  The relay adapter 28 generates an error code indicating an error or failure acquired from the heat source device 3 or the like from the management center 30 or voluntarily to the management center 30 as shown in FIGS. 10 and 11, for example. Perform call processing. Thereby, the management center 30 side can grasp and recognize a failure or the like from the change in the operation mode generated in the heat source unit 3 and the like, and can take a quick and accurate response.

  FIGS. 10 and 11 show an example of an error code calling process. 10 and FIG. 11, A, B, and C show the connection part between flowcharts.

  In step S1201, for example, it is determined whether or not a change in the operation mode has occurred in the heat source device 3, its terminals 6, 10, the HA terminal 32, the device 34, and the like. In this program, it waits in this step S1201 until a change occurs in the operation mode.

  When a change occurs in the operation mode, the process proceeds to step S1202, and it is determined whether or not the change in the operation mode occurs in the heat source apparatus 3. If not, the process proceeds to step S1203 and the heat source apparatus is determined. It is determined whether the three-side terminals 6 and 10 are other devices, that is, the HA terminal 32 and the device 34.

  When the operation mode has changed in the heat source unit 3, the process proceeds to step S1204. In step S1204, the operation mode of the heat source unit 3 is called from the heat source unit 3 to the relay adapter 28, that is, transmitted. If it is determined in step S1203 that the terminals 6 and 10 are on the heat source unit 3 side, the process proceeds to step S1205, and the terminal 6 or 10 calls the operation mode of the terminal 6 or 10 to the heat source unit 3. . In step S1206, the operation mode called from the terminal 6 or 10 is stored in the EEPROM of the control device 16 of the heat source unit 3, and in step S1207, the operation mode is called to the relay adapter 28.

  In step S1208, the operation mode called from step S1204 and the operation mode called from step S1207 are stored in the RAM 72 of the relay adapter 28. In the storage process, even when it is determined in step S1203 that the device is another device, the operation mode from the device is stored in the RAM 72 of the relay adapter 28. After the storage process is completed, it is determined in step S1209 whether the heat source device 3 or the terminals 6, 10 or other devices are in operation. If it is not in operation, the process returns to step S1201 and the processes of steps S1201 to 1209 are repeated.

  When it is determined in step S1209 that the heat source device 3 or the terminals 6, 10 or other devices are in operation, the process proceeds to step S1210, where real-time data regarding the operation mode is collected, and in step S1211, the latest acquired The data is stored in the RAM 72. In this case, the latest data is overwritten and saved on the previous data, that is, the data is updated.

  After the update of the latest data, in step S1212, it is determined whether or not the heat source unit 3 or the terminals 6 and 10 has issued an error code. If the error code has been issued, the process proceeds to step S1213. The error code is overwritten on the EEPROM 90 and stored, and the error code is stored with time stamp data as time information.

  In step S1214, the abnormal time data is overwritten on the RAM 72 and stored, and the abnormal time data is also appended with time stamp data as time information.

  In step S1215, it is determined whether or not the error code has a call restriction condition. If the error code does not have a call restriction condition, the process proceeds to step S1216 to select necessary data.

  In this case, if the error code has a call restriction condition, it is determined in step S1217 whether or not the call restriction condition is satisfied. If the error code is satisfied, the process returns to step S1201, and the condition is not satisfied. In this case, the process proceeds to step S1216, and necessary data is selected.

  After selecting the necessary data, in step S1218, the error code and the selected data are transmitted from the relay adapter 28 to the management center 30 side, and in step S1219, the management center 30 side uses the error code and data for failure. The parts are identified, the cause of failure is analyzed, and the data required for repair is sent to the maintenance staff. This data transmission is transmitted to an information terminal 64 such as a fax machine installed in the maintenance store.

  By the way, when the heat source device 3 or the terminals 6 and 10 do not call out an error code in step S1212, it is determined in step S1220 whether or not a specified time has passed for a time during which the error code is not called. If the specified time has not elapsed, the process proceeds to step S1221 (FIG. 10), and it is determined whether or not the heat source device 3 or the terminals 6 and 10 are operating. If not, the process returns to step S1201 to operate. If it is in the middle, the process proceeds to step S1210, and the process of step S1210 is performed.

  If the time when the error code is not called has reached the specified time, the process proceeds to step S1222, and normal time data is overwritten and saved in the RAM 72 for each operation mode. Add stamp data and save. This stored data is a target of data selection processing in step S1216.

  In this processing mode, when the relay adapter 28 is energized, the relay adapter 28 requests the invariant data from the heat source unit 3 in step S1223. In step S1224, the relay adapter 28 receives the invariant data acquired from the heat source unit 3. Is overwritten on the EEPROM 90 and is stored by adding time stamp data, which is time information, to the invariant data. This stored data is also a target of the data selection process in step S1216.

  In this processing mode, in step S1225, the relay adapter 28 periodically requests integration system data from the heat source unit 3, and in step S1226, the relay adapter 28 receives the integration system data acquired from the heat source unit 3 as data. The EEPROM 90 is overwritten and stored, and the time stamp data, which is time information, is added to the integration system data and stored. This stored data is also a target of the data selection process in step S1216.

  According to such processing, in response to a request from the management center 30 side, the operation status and control information of the heat source unit 3, its terminals 6, 10, HA terminal 32, equipment 34, and relay adapter 28 can be quickly obtained at the management center 30 side. It is possible to grasp and take prompt action such as failure repair based on the grasp, and to realize highly reliable remote management.
