Abstract
The present invention relates to a central management device and a time adjustment method for an air conditioning system. A system controller (40) as a central management device of an air conditioning system (1) to which a remote controller (30) is connected is provided with a central built-in clock (41), a time correction timing setting unit (43), and a time correction processing unit (44). The remote controller (30) has a remote controller built-in clock (33) and has a timer function based on the timing of the remote controller built-in clock. The time adjustment timing setting unit (43) sets time adjustment timing information indicating a time other than "0" or "5" in units of minutes as a timing at which the time adjustment processing of the internal clock (33) is performed. When it is determined that the time of the central internal clock reaches the time indicated by the time correction timing information, the time correction processing unit (44) transmits a correction instruction to the remote controller (30) to correct the time counted by the remote controller internal clock to the time of the central internal clock.
Description
Technical Field
Embodiments of the present invention relate to a central management device and a time adjustment method for an air conditioning system.
Background
A multi-type air conditioning system in which 1 outdoor unit is connected to a plurality of indoor units is mounted in a large building such as a commercial facility or an office building. Remote controllers are connected to the indoor units of such an air conditioning system, and users can operate the corresponding indoor units using the remote controllers.
In general, a remote controller of an indoor unit incorporates a clock and a timer function, and the timer function is executed based on the time of the clock. For example, when a user performs a timer setting operation through a remote controller to start operation of the corresponding indoor unit at a predetermined time, the remote controller monitors whether or not the time has come based on the timing of a built-in clock, and when it is determined that the time has come, transmits an operation start instruction to the connected indoor unit.
The internal clocks of the plurality of remote controllers in these air conditioning systems perform the time counting operation individually, and gradually deviate from the correct time as time passes. To cope with this situation, there are techniques as follows: the time adjustment process is executed for these internal clocks at predetermined intervals based on a standard time acquired from the outside. For example, a central management device is installed above a plurality of air conditioning systems, and the internal clock of each air conditioning system is corrected using the time of the internal clock of the central management device as a standard time.
By periodically performing the time adjustment process on the remote controller in the air conditioning system, it is possible to avoid a large deviation in the timing of these built-in clocks, and to appropriately perform the timer function and the like.

Disclosure of Invention
When the time adjustment process is performed on the remote controller or the like in the air conditioning system as described above, if a delay occurs in the clock built in the calibration target, the time adjustment process is executed to shift the counted time to a predetermined period of time later. Therefore, an untimed blank period is generated in the internal clock.
Here, in the remote controller, when a timer relating to a certain operation is set with the time within the blank period as the execution time, the time is not counted, and therefore, the corresponding operation cannot be executed.
For example, when the built-in clock of the remote controller is slower than the standard time by 10 seconds and is counting time by 11 hours, 59 minutes and 50 seconds, and when a time correction instruction to 12 hours 00 minutes (00 seconds) is obtained by the time correction processing, the counting time of the built-in clock shifts to the time, and the period from immediately after 50 seconds by 11 hours, 59 seconds and 50 seconds to 12 hours and 00 minutes becomes a blank period. In this remote controller, when the timer is set to start operation at time 12 and 00, depending on the method of creating the program for timer operation, the time may become a blank period of the built-in clock and not be counted, and the operation start operation may not be executed.
When the timing of the internal clock to be corrected is advanced, the timing correction process is executed to shift the timing to a predetermined period before. Therefore, a repetition period that is clocked twice is generated in the built-in clock. Here, in the remote controller, when a timer concerning a certain operation is set with the time within the repetition period as the execution time, the operation executed by the timer function when the time is measured for the first time is cancelled by the operation of the user or the like immediately after the cancellation, and the operation is executed again by the timer function when the time is measured for the 2 nd time, which may cause inconvenience to the user.
For example, when the built-in clock of the remote controller is 20 seconds before the standard time and is counting 12 hours 00 minutes 20 seconds, and when a time correction instruction to 12 hours 00 minutes (00 seconds) is obtained by the time correction processing, the counting time of the built-in clock shifts to the time, and the period from 12 hours 00 minutes to 12 hours 00 minutes 20 seconds becomes the repetition period. In this remote controller, when the timer is set to start operation at 12 hours 00, the timer function starts operation of the corresponding indoor unit when 12 hours 00 minutes have been counted at the 1 st time (before the time adjustment processing). Immediately after that, even if the user operates the remote controller to stop the indoor unit, the time counted by the time correction processing shifts from 12 hours 00 minutes to 20 minutes to 12 hours 00 minutes.
Therefore, when the 12 th hour 00 hour is counted at the 2 nd time, the operation of the air conditioner may be restarted by the timer function, and in this case, the operation which is not intended by the user may be performed.
As a result, when the time set by the timer and the corrected time overlap, there is a problem that the operation based on the timer setting is performed or is not performed.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a central management device and a time adjustment method for an air conditioning system, which perform time adjustment processing of a clock incorporated in a device while appropriately operating the device in the air conditioning system.
In order to achieve the above object, a central management device for an air conditioning system according to the present invention is a central management device for an air conditioning system communicably connected to a remote controller having a clock incorporated in the remote controller and a timer function for counting time based on the clock incorporated in the remote controller, the central management device including: a clock is arranged in the center to time the time; a time adjustment timing setting unit that sets time adjustment timing information indicating a time other than "0" or "5" in units of minutes as a timing at which the time adjustment processing of the remote controller built-in clock is performed; and a time adjustment processing unit that, when it is determined that the time of the central built-in clock reaches the time indicated by the time adjustment timing information set by the time adjustment timing setting unit, transmits to the remote controller an adjustment instruction to adjust the time kept by the remote controller built-in clock to the corresponding time.
In addition, a time adjustment method of an air conditioning system according to the present invention is characterized in that a central management device is communicably connected to a remote controller having a remote controller built-in clock and a timer function based on the time measurement of the remote controller built-in clock, and includes a central built-in clock for measuring time, and the central management device sets time adjustment timing information in which time adjustment instructions for adjusting the time of the remote controller built-in clock to the time of the central built-in clock are transmitted to the remote controller when the time of the central built-in clock is determined to reach the time indicated by the set time adjustment timing information, the time adjustment timing information indicating a time other than a time at which a bit value in minutes is "0" or "5" as a timing for performing time adjustment processing of the remote controller built-in clock.

Detailed Description
EXAMPLE 1
< configuration of air conditioning system using central control device according to embodiment 1 >
The configuration of an air conditioning system using a central management device according to embodiment 1 of the present invention will be described with reference to fig. 1. The air conditioning system 1A of the present embodiment includes: an outdoor unit 10 installed in a predetermined building; a plurality of indoor units (1 st indoor unit 20a, 2 nd indoor unit 20b, and 3 rd indoor unit 20 c) connected to the outdoor unit 10 by refrigerant pipes and communication lines; a plurality of remote controllers (a 1 st remote controller 30a, a 2 nd remote controller 30b, and a 3 rd remote controller 30 c) which are respectively connected to the plurality of indoor units in a communication manner; and a system controller 40 as a central management device connected to the outdoor unit 10.
In the present embodiment, a case where 3 indoor units and 3 remote controllers are connected to the outdoor unit 10 will be described, but more indoor units and more remote controllers may be connected.
In the present embodiment, the indoor unit 20 is described as the indoor unit 20 when it is not necessary to specify which of the indoor units 20a, 20b, and 20c is. Similarly, the remote controller 30 is described as a remote controller 30 when it is not necessary to specify which of the remote controllers 30a, 30b, and 30c is.
The outdoor unit 10 includes an outdoor unit built-in clock 11, an outdoor-indoor communication unit 12, an outdoor-central communication unit 13, and an outdoor unit operation control unit 14. The outdoor-indoor communication unit 12 communicates with each of the indoor units 20a, 20b, and 20 c. The outdoor-central communication section 13 communicates with the system controller 40. The outdoor unit operation control unit 14 controls operations related to the devices in the outdoor unit 10 including the time correction processing of the outdoor unit internal clock 11, based on an instruction transmitted from the system controller 40. When receiving an instruction transmitted from the system controller 40 to any of the indoor units 20, the outdoor unit operation control unit 14 transmits the instruction to the corresponding indoor unit 20.
The 1 st indoor unit 20a includes an indoor unit built-in clock 21, an indoor-remote controller communication unit 22, an indoor-outdoor communication unit 23, and an indoor unit operation control unit 24. The indoor-remote-controller communication unit 22 communicates with the corresponding 1 st remote controller 30a. The indoor-outdoor communication unit 23 communicates with the outdoor unit 10.
The indoor unit operation control unit 24 controls operations related to the devices in the indoor unit 20a based on an instruction transmitted from the system controller 40 and transmitted from the outdoor unit 10 and an instruction transmitted from the 1 st remote controller 30a connected thereto. When receiving the time adjustment instruction transmitted from the system controller 40, the indoor unit operation control unit 24 transmits the instruction to the 1 st remote controller 30a connected thereto.
The 2 nd indoor unit 20b and the 3 rd indoor unit 20c have the same configuration as the 1 st indoor unit 20a, and therefore detailed description thereof is omitted.
The 1 st remote controller 30a includes a remote controller-room communication unit 31, an operation input unit 32, a remote controller-built-in clock 33, a timer setting unit 34, a time adjustment execution unit 35, and a display unit 36.
The remote controller-indoor communication unit 31 communicates with the corresponding indoor unit 20a. The operation input unit 32 inputs user operation information and appropriately transmits the information to the indoor unit 20a.
The timer setting unit 34 sets a timer for monitoring the arrival of a predetermined operation related to the indoor unit 20a and the execution time of the operation when operation information specifying the operation and the execution time is input from the operation input unit 32. When it is determined that the time comes based on the timing of the clock built in the remote controller, the operation input unit 32 is notified of the arrival of the execution time of the operation. As the timer setting contents, there are start or stop of operation of the indoor unit 20a at a predetermined time and a combination of start and stop of operation. Further, in the setting of the operation start, the mode of the operation to be started, such as cooling, heating, dehumidification, and air blowing, the set temperature, the set humidity, and the like can be specified. Although not shown, the 1 st remote controller 30a is provided with a clock display unit so that the user can recognize the current time. The user sets the timer time based on the recognition of the displayed current time.
The time adjustment execution unit 35 executes the time adjustment process of the remote controller built-in clock 33 when receiving the time adjustment instruction transmitted from the system controller 40. The display unit 36 displays information generated based on the operation information input from the operation input unit 32, information of the time being counted by the remote control built-in clock 33, and the like.
The 2 nd and 3 rd remote controllers 30b and 30c have the same configuration as the 1 st remote controller 30a, and thus detailed description thereof is omitted.
Fig. 2 shows a front view of the 1 st, 2 nd and 3 rd remote controllers 30a, 30b, 30 c. In the lower front part of the remote controller 30, an "operation/stop" button 321, a "menu" button 322, an up arrow button 323, a down arrow button 324, and a "cancel" button 325 are provided as an operation input unit 32, and a display unit 36 including a monitor screen is provided in the upper part thereof.
The system controller 40 includes a controller built-in clock 41 as a central built-in clock, an operation input unit 42, a time adjustment timing setting unit 43, and a time adjustment processing unit 44.
The operation input unit 42 is an operation unit for the administrator to input information related to the group operation and the schedule operation of the air conditioning system 1A. The time adjustment timing setting unit 43 sets time information indicating a timing at which a preset time adjustment process is performed as time adjustment timing information.
The controller-incorporated clock 41 is a clock having a higher timing accuracy than other internal clocks in the air conditioning system 1A, or is a clock designed to make the timing of its own timing coincide with a standard time by periodically acquiring standard time information from the standard clock, for example, the internet, thereby making the timing accuracy higher than other internal clocks.
The time adjustment processing unit 44 is configured to transmit a time adjustment instruction to correct the time counted by each internal clock to the time counted by the controller-internal clock 41 to the devices in the air-conditioning system 1A when it is determined that the time counted by the controller-internal clock 41 reaches the time indicated by the time adjustment timing information set by the time adjustment timing setting unit 43.
< operation of air conditioning system according to embodiment 1 >
Next, the operation of the air conditioning system 1A of the present embodiment will be described. In the present embodiment, the user can operate the connected indoor unit 20 by using the timer function of the remote controller 30. The procedure of the timer setting operation performed by the user via the remote controller 30 in order to operate the indoor unit 20 using the timer function will be described.
As shown in fig. 2, the display unit 36 of the remote controller 30 displays information such as the installation location of the corresponding indoor unit 20 and the current set temperature at normal times. When the user operates the "menu" button 322 of the remote controller 30, the display content of the display unit 36 is switched to an operation menu screen that shows a plurality of setting items related to the connected indoor unit 20. Examples of the setting items displayed on the operation menu screen include "wind direction setting", "shutter operation setting", and "timer setting".
Next, when the user operates the up arrow button 323 or the down arrow button 324 to select the setting item "timer setting" on the displayed operation menu screen, the display content of the display unit 36 is switched to a timer setting screen indicating the type of timer that can be set by the timer setting function. The set timer type displayed on the timer setting screen includes, for example, "off timer" for stopping the operation of the indoor unit 20 at a designated time, "on timer" for starting the operation of the indoor unit 20 at a designated time, and the like.
Next, when the user operates the up arrow button 323 or the down arrow button 324 to select an operation of "start timer" on the timer setting screen displayed, the display content of the display unit 36 is switched to the start timer setting screen for inputting information related to the setting of the start timer. The on-timer setting screen includes information for inputting the time at which the operation of the indoor unit 20 is started.
Next, when the user operates the up arrow button 323 or the down arrow button 324 to input a desired time on the displayed on-timer setting screen, the on-timer for starting the operation of the corresponding indoor unit 20 at the time is set in the timer setting unit 34.
In general, the time designated in the timer setting operation of the indoor unit 20 is often the time when the value of one digit in minutes is "0" or "5", and in the present embodiment, the time "12 hours 00 minutes" is designated and the on timer is set.
Next, the time adjustment process performed on the internal clock of each device in the air conditioning system 1A will be described with reference to the timing chart of fig. 3.
In the present embodiment, time information indicating the timing at which the preset time adjustment process is performed is set in the time adjustment timing setting unit 43 (S1). The time adjustment timing information is configured to be settable in units of minutes, and the ones-digit value in units of minutes is set to a time other than "0" or "5".
The time adjustment processing unit 44 receives as a standard time the time measured by the controller-included clock 41, and monitors whether or not the time of the controller-included clock 41 matches the time adjustment timing set by the time adjustment timing setting unit 43, that is, whether or not the monitoring time adjustment timing has come (S2).
When it is determined that the time adjustment timing has come (yes in S2), the time adjustment processing unit 44 transmits a time adjustment instruction for adjusting the time counted by the built-in clock to the standard time from the center-outdoor communication unit 45 to the outdoor unit 10 (S3).
The time adjustment instruction transmitted from the system controller 40 is received by the outdoor-central communication unit 13 of the outdoor unit 10. Then, based on the received time adjustment instruction, the outdoor unit operation control unit 14 adjusts the outdoor unit built-in clock 11 at the corresponding standard time, and transmits the time adjustment instruction from the outdoor-indoor communication unit 12 to the connected indoor units 20a to 20c (S4).
The timing correction instruction transmitted from the outdoor unit 10 is received by the indoor-outdoor communication unit 23 of each of the indoor units 20a to 20 c. Then, based on the received time adjustment instruction, the indoor unit operation control unit 24 adjusts the indoor unit built-in clock 21 at the corresponding standard time, and transmits the time adjustment instruction from the indoor-remote controller communication unit 22 to the remote controllers 30a to 30c connected thereto, respectively (S5, S6, and S7).
The timing correction instructions received from the indoor units 20a to 20c are received by the remote controller-indoor communication unit 31 of the remote controllers 30a to 30 c. Then, based on the received time adjustment instruction, the remote controller internal clock 33 is adjusted at the corresponding standard time by the time adjustment execution unit 35.
By executing the processing in this manner, when the variation of the remote controller built-in clock 33 of the remote controller 30 is less than 1 minute, the time correction is not performed at the time when the value of one bit in units of minutes is "0" or "5" in the remote controller built-in clock 33. Thus, in the timer setting related to the operation of the indoor unit 20, when the time at which the value of the unit bit in minutes is "0" or "5" is set, the possibility that the time corresponds to the blank period or the repetition period due to the time adjustment processing is low.
Further, the details will be described with reference to fig. 4. For example, when the time adjustment timing is set to 11 hours and 56 minutes and a delay of less than 1 minute occurs in the remote controller built-in clock 33, the remote controller 30 corrects the counted time as indicated by an arrow P1 by the time adjustment processing. Similarly, in a state where a delay of less than 1 minute occurs in the internal clock, the time keeping time is corrected as indicated by an arrow P2 when the time correction timing is set to 11 hours and 57 minutes, the time keeping time is corrected as indicated by an arrow P3 when the time correction timing is set to 11 hours and 58 minutes, the time keeping time is corrected as indicated by an arrow P4 when the time correction timing is set to 11 hours and 59 minutes, and the time keeping time is corrected as indicated by an arrow P5 when the time correction timing is set to 12 hours and 01 minutes.
When the time adjustment timing is set to 11 hours and 56 minutes and the remote controller internal clock 33 is advanced by less than 1 minute, the remote controller 30 corrects the time-keeping time as indicated by an arrow Q1 by the time adjustment process. Similarly, in a state where the built-in clock generates an advance of less than 1 minute, the chronograph time is corrected as indicated by an arrow Q2 when the time correction timing is set to 11 hours and 57 minutes, the chronograph time is corrected as indicated by an arrow Q3 when the time correction timing is set to 11 hours and 58 minutes, the chronograph time is corrected as indicated by an arrow Q4 when the time correction timing is set to 11 hours and 59 minutes, and the chronograph time is corrected as indicated by an arrow Q5 when the time correction timing is set to 12 hours and 01 minutes.
By performing the time adjustment as described above, the operation specified by the timer setting can be appropriately and reliably executed.
EXAMPLE 2 EXAMPLE
The configuration of an air conditioning system 1B using the central management device according to embodiment 2 of the present invention is the same as the configuration of the air conditioning system 1A shown in fig. 1 described in embodiment 1, and therefore detailed description of portions having the same functions is omitted.
In the present embodiment, the time designated in the timer setting operation of the indoor unit 20 can be set in units of minutes, and any one of the values "0" to "59" can be input. The system controller 40 is configured to be able to set the time adjustment timing information in units of seconds. Then, the time adjustment timing setting unit 43 sets a time indicating "30" as time adjustment timing information in units of seconds.
In the state where the time adjustment timing information is set in this manner, as in the processing described in embodiment 1, when the time adjustment processing is executed, if the variation in the remote controller built-in clock 33 of the remote controller 30 is less than 30 seconds, the time adjustment is not performed across the time at which the value in seconds is "0" in the remote controller built-in clock 33.
Thus, in the timer setting related to the operation of the indoor unit 20, the time does not correspond to the blank period or the repetition period due to the time adjustment process, regardless of the time at which the value in minutes is set from "0" to "59".
Further, the details will be described with reference to fig. 5. For example, when the time adjustment timing is set to 11 hours 55 minutes 30 seconds and the remote controller internal clock 33 causes a delay of less than 30 seconds, the remote controller 30 corrects the counted time as indicated by an arrow P11 by the time adjustment process. Similarly, in a state where the internal clock has a delay of less than 30 seconds, the chronograph time is corrected as indicated by an arrow P12 when the time correction timing is set to 11 hours 56 minutes 30 seconds, the chronograph time is corrected as indicated by an arrow P13 when the time correction timing is set to 11 hours 57 minutes 30 seconds, the chronograph time is corrected as indicated by an arrow P14 when the time correction timing is set to 11 hours 58 minutes 30 seconds, the chronograph time is corrected as indicated by an arrow P15 when the time correction timing is set to 11 hours 59 minutes 30 seconds, and the chronograph time is corrected as indicated by an arrow P16 when the time correction timing is set to 12 hours 00 minutes 30 seconds.
When the time adjustment timing is set to 11 hours 55 minutes 30 seconds and the remote controller internal clock 33 advances by less than 30 seconds, the remote controller 30 corrects the counted time as indicated by an arrow Q11 by the time adjustment process. Similarly, in a state where the built-in clock generates an advance of less than 30 seconds, the chronograph time is corrected as indicated by an arrow Q12 when the time correction timing is set to 11 hours 56 minutes 30 seconds, the chronograph time is corrected as indicated by an arrow Q13 when the time correction timing is set to 11 hours 57 minutes 30 seconds, the chronograph time is corrected as indicated by an arrow Q14 when the time correction timing is set to 11 hours 58 minutes 30 seconds, the chronograph time is corrected as indicated by an arrow Q15 when the time correction timing is set to 11 hours 59 minutes 30 seconds, and the chronograph time is corrected as indicated by an arrow Q16 when the time correction timing is set to 12 hours 00 minutes 30 seconds.
By performing the time adjustment as described above, even when the time is specified by a fine numerical value as in 58 minutes and 00 seconds at time 11, for example, in the timer setting, the corresponding operation can be appropriately and reliably performed.
EXAMPLE 3 rd embodiment
The configuration of the air conditioning system 1C using the central management device according to embodiment 3 of the present invention is the same as the configuration of the air conditioning system 1A shown in fig. 1 described in embodiment 1, and therefore detailed description of portions having the same functions is omitted.
In the present embodiment, the time designated in the timer setting operation of the indoor unit 20 can be set in units of minutes, and it is assumed that the unit bit value in units of minutes is "0" or "5" in many cases, as in embodiment 1.
Further, the system controller 40 is configured to be able to set the time adjustment timing information in units of seconds, as in embodiment 2, and the time adjustment timing setting unit 43 is configured to set, as the time adjustment timing information, a time at which the value of one digit in units of minutes is "2" or "7" and the value in units of seconds indicates "30".
In the state where the time adjustment timing information is set in this way, when the time adjustment process is executed, the time is not corrected beyond the time at which the one-bit value in minutes is "0" or "5" in the remote controller internal clock 33 when the variation of the remote controller internal clock 33 of the remote controller 30 is less than 2 minutes and 30 seconds, as in the process described in embodiment 1.
Thus, when the time at which the unit bit value in minutes is "0" or "5" is set in the timer setting relating to the operation of the indoor unit 20, the possibility that the time corresponds to a blank period or a repeat period due to the time adjustment processing is further reduced.
Further, the detailed description is made with reference to fig. 6. For example, when the time adjustment timing is set to 11 hours, 57 minutes, and 30 seconds, and the remote controller internal clock 33 causes a delay of less than 2 minutes and 30 seconds, the remote controller 30 corrects the clock time as indicated by an arrow P21 by the time adjustment process.
When the time adjustment timing is set to 11 hours, 57 minutes, and 30 seconds, and the remote controller internal clock 33 is advanced by less than 2 minutes and 30 seconds, the remote controller 30 corrects the clock time by the time adjustment process as indicated by an arrow Q21.
By performing the time adjustment in this manner, the timer setting can be performed appropriately and reliably with high accuracy.
According to the above-described embodiments 1 to 3, the timing correction process of the remote controller built-in clock 33 of each remote controller 30 is executed while avoiding the timing at which the timer relating to the operation of the indoor unit 20 is likely to be set. Thus, when the timer setting operation is performed on the remote controller 30, the possibility that the time designated by the timer setting corresponds to the blank period or the overlap period generated by the time adjustment process is reduced, and it is possible to avoid a situation in which the operation designated by the user cannot be appropriately performed as much as possible.
In the above embodiment, the examples were described in which the built-in clocks 11 and 21 were provided in the outdoor unit and the indoor unit, respectively, but in the case of the system in which all of the timer setting and the timer operation for instructing the operation/stop are instructed from the remote controller 30, only the remote controller built-in clock 33 of the remote controller 30 may be provided without providing these built-in clocks 11 and 21.
Further, in the above-described embodiment, the case where the system controller 40 as the central management device and the remote controller 30 are communicably connected via the outdoor unit 10 and the indoor unit 20 has been described, but the connection method is not limited to this.
For example, the system controller 40 and all of the outdoor unit 10, the indoor unit 20, and the remote controller 30 may be individually and directly connected, or all of the devices, that is, the system controller 40, the remote controller 30, the outdoor unit 10, and the indoor unit 20 may be communicably connected to one bus. Further, the devices may be connected to each other so as to be able to communicate wirelessly.
Several embodiments of the present invention have been described, but the embodiments are presented as examples and are not intended to limit the scope of the invention. The new embodiment can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. The embodiment and the modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the scope equivalent thereto.
