[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a central control device,
In particular, the present invention relates to a centralized control device for centrally controlling a plurality of air conditioners.

[0002]

2. Description of the Related Art Conventionally, a common outdoor unit and a common main controller are provided, a plurality of indoor units are connected to a main controller via a sub-controller and a communication line, and the whole system is controlled by the main controller. There is an air conditioning centralized management system in which a sub-controller provided on a user side locally controls an indoor unit connected to the sub-controller.

In such a centralized cooling and heating management system, in order to obtain the same cooling and heating capacity, the cost and the installation area are reduced as compared with the case where an outdoor unit and an indoor unit are individually provided (hereinafter referred to as an individual management system). It was advantageous from the point.

By the way, in an individual management system,
Since the user only has to pay the electricity rate, the gas rate, and the like based on the electric meter, the gas meter, and the like in accordance with the usage state, there is no need to specially manage the usage state.

On the other hand, in the above-mentioned centralized management system, it is necessary to share the operating cost of the cold heat source, which is a common part, among a plurality of users.

[0006] When calculating the sharing cost, there is a method of uniformly sharing each user, but there is a difference in usage time, usage state (for example, required cooling capacity) and the like. Due to unfairness, a method has been adopted in which the sharing ratio is determined according to the number of indoor units installed by each user.

[0007]

However, in the method of determining the sharing ratio as described above, since the use time, the use state, and the like differ for each user, unfairness is not necessarily eliminated. was there.

In the above-mentioned conventional centralized management system, only one indoor unit can be connected to each sub-controller.

Therefore, for example, even when 16 indoor units can be connected to one sub-controller, if eight indoor units are provided in two systems, two sub-controllers must be provided. The equipment resources cannot be used effectively,
There is a problem that the cost of the entire system increases.

Accordingly, a first object of the present invention is to provide a centralized control device capable of accurately grasping the use state of each controlled device even when a large number of controlled devices are installed. Accordingly, it is an object of the present invention to provide a centralized control device capable of accurately grasping the usage ratio of each controlled device to the usage state of the entire system and fairly sharing costs.

It is a second object of the present invention to simplify the configuration of the entire system even when a plurality of controlled devices are installed, to effectively use the device resources, and to reduce the installation cost. It is an object of the present invention to provide a centralized control device capable of reducing the number of times.

[0012]

In order to solve the above problems, a first invention is directed to a plurality of controlled device groups each including a plurality of controlled devices, and one or a plurality of the controlled device groups. Each is connected via a sub communication line, monitors the operation state of each controlled device, collects and integrates operation state data, and converts the obtained integrated operation state data using predetermined reference operation state data. A terminal processing control device that calculates an operation ratio of all the controlled devices of the controlled device with respect to an operation state and outputs the operation ratio as apportioned data; and an apportioned data from the terminal processing control device that is input and uses the controlled device. And a management control device for managing.

According to a second aspect of the present invention, there are provided a plurality of controlled device groups each including a plurality of controlled devices, and a plurality of communication connection terminals, wherein the communication connection terminals include the controlled device. A group is connected via a sub communication line, and a terminal processing control device for independently controlling a group of controlled devices connected to each communication connection terminal, and a terminal processing device connected to the terminal processing device via a main communication line. And a central processing control device that controls the entire system, wherein the terminal processing control device includes a communication connection terminal that has actually received communication data from the controlled device group side among the plurality of communication connection terminals. There is provided a determining means for determining, and a control means for incorporating the controlled device group connected to the communication connection terminal receiving the communication data into its own control system based on the determination result of the determining means.

[0014]

[0015]

According to the first aspect of the present invention, the terminal processing control device monitors the operation status of each controlled device connected via the sub communication line, collects and accumulates the operation status data, and obtains the obtained integration. The operation state data is converted using predetermined reference operation state data, and the operation ratio of the controlled apparatus to the operation states of all the controlled apparatuses is obtained and output to the management control apparatus as apportioned data.

Thus, the management control device manages the use state of the controlled device based on the apportionment data which is a function of the reference operation state data.

Therefore, even when a large number of controlled devices are installed, the use state of each controlled device can be accurately grasped using the apportioning data which is a function of the reference operation state data. At the same time, it is possible to accurately grasp the operation ratio of each controlled device with respect to the operation state of the entire system and fairly share costs and the like.

According to the second invention, the terminal processing control device independently controls the controlled device groups connected via the communication connection terminal and the sub-communication line, and the central control device performs the terminal processing. The entire system including the entire controlled device is controlled via the control device and the main communication line. In addition, the terminal processing control device includes a determination unit that determines a communication connection terminal that has actually received communication data from the controlled device group side among the plurality of communication connection terminals, and a determination result of the determination unit. Control means for incorporating the controlled device group connected to the communication connection terminal that has received the communication data into its own control system based on the above.

Therefore, a group of controlled devices in a plurality of systems can be independently controlled by one terminal processing control device, so that device resources can be effectively used and the flexibility and ease of system construction are improved. . Further, a controlled device group that does not transmit communication data to the terminal processing device side via the communication connection terminal, that is, if the controlled device group is not connected to the communication connection terminal, or is connected to the communication connection terminal. However, since the non-control device group that is in the non-operation state is not incorporated in the control system, the processing load on the terminal processing device can be reduced.

Controlled devices U11 to U1n such as an indoor unit and an outdoor unit are connected via an interface unit 13A, a communication connection terminal T1 and a sub communication line LS21, and further, the controlled devices U21 to U2n are connected to an interface unit 13A. Connection terminal T2 and the sub communication line LS22.

Here, the operation of incorporating the controlled device group of the communication adapter 3-2 into the control system will be described with reference to the processing flowchart of FIG. FIG. 4 illustrates, as a general expression, a case where the number of communication connection terminals is n, that is, the maximum number of controllable systems is n. In the following description, a case where there are two communication connection terminals, that is, a communication connection terminal T1 and a communication connection terminal T2 (when n = 2) will be described.

The CPU 1 reads out the communication data stored in the RAM 1 (step S1), and the controlled device connected to the same sub communication line (= controlled device of the same system)
The initial value of a variable m for specifying one controlled device group consisting of is set to 1 (step S2).

Next, the CPU 1 includes in the read communication data the m-th system, that is, the first system controlled device group (in this case, the controlled device connected to the communication connection terminal T1 and the sub communication line LS21). Controlled devices U11 to U constituting the device group)
It is determined whether or not communication data (received data) from any one of 1n is included (step S3).

If it is determined in step S3 that communication data (received data) from any one of the controlled devices U11 to U1n constituting the first system controlled device group is included, the first system is controlled. Is in an operating state, the CPU controls the first group of controlled devices in order to control the first system.
It is incorporated into the control system (step S4). That is, the operation state is monitored at each predetermined timing based on the received data, and a control command is transmitted as communication data as needed.

If it is determined in step S3 that the communication data from the controlled devices U11 to U1n constituting the first system controlled device group is not included, the first system controlled device group is connected. Is not in operation or in a non-operation state (for example, the power is not turned on), the CPU 1 shifts the processing to the processing of step S5, and sets the control system to the control system until the next communication data is read. Does not incorporate and does not perform any control.

Next, the CPU 1 adds 1 to the variable m (step S5), and determines whether the value of the variable m exceeds the maximum number n of controllable systems of the communication adapter 3-2 (n = 2 in this case). It is determined whether or not it is (step S6).

If it is determined in step S6 that the variable m exceeds the maximum number n of systems, the process of incorporating the controlled device group into the control system ends.

If it is determined in step S6 that the variable m does not exceed the maximum number n of systems, the process proceeds to step S6.
Then, the process proceeds to step S3, and the processes of steps S3 to S6 are repeated.

More specifically, in the case of the present embodiment, since m = 2 n = 2 at this point, the processing shifts to step S3, where the second communication data is included in the read communication data. Control devices (in this case,
It is determined whether or not communication data (received data) from any of the controlled devices U21 to U2n constituting the controlled device group connected to the communication connection terminal T2 and the sub communication line LS22 is included (see FIG. 4). Step S3).

In the same manner, the processing of steps S4 to S6 is performed in the same manner, and the operation of incorporating the controlled devices into the control system is completed.

Although the communication adapter 3-2 controls two groups of controlled devices, the communication adapter may be similarly configured to control three or more groups of controlled devices. It is possible.

As described above, by using a communication adapter capable of controlling a plurality of groups of controlled devices, it is possible to easily centrally control a group of controlled devices without increasing the number of communication adapters.

Even when the number of systems of the non-control device group to be controlled increases, the number of communication adapters does not need to be provided in proportion to the number of systems, and device resources can be used effectively.

Further, if one communication adapter is provided, it is possible to variously configure the connection modes of the controlled devices connected to the communication adapter, and it is possible to improve flexibility and easiness in system construction. .

Next, the mode of the controlled device group UG will be described with reference to FIG. 1 again.

Various modes of the controlled device group UG can be considered, and an example will be described below.

The first communication adapter 3-1 has a sub communication line L
A plurality of indoor units 20 and an outdoor unit controller 21 are connected via S1, and a plurality of outdoor units 22 are connected via the outdoor unit controller 21.

A plurality of indoor units 20 and one outdoor unit 22 are connected to the second communication adapter 3-2 via the first sub communication line LS21.
Are connected, and a second controlled device group to which a plurality of indoor units 20 and one outdoor unit 22 are similarly connected via the second sub-communication line LS22 is connected. I have.

The third communication adapter 3-3 has a sub communication line L

Is connected.

Before describing the operation of the entire system, the work sharing (processing sharing) of the communication adapters 3-1 to 3-3 and the main controller 2 in the cooling and heating system 1 will be described.

As shown in FIG. 5, the basic functions of the cooling and heating system 1 include an apportioning information function, a setting function, and a display function.

In these three basic functions, the apportioning information function is shared as the work (process) of the communication adapters 3-1 to 3-3, and the setting function and the display function are shared as the work (process) of the main controller. ing.

The apportionment information function is based on operation data indicating whether the indoor unit or the outdoor unit as each controlled device connected to one communication adapter is in an operation / stop state, and a fan of each controlled device. Wind speed data indicating wind speed (sudden, strong, weak, etc.), thermostat on data indicating whether the thermostat is on (operating), electric heater on data indicating whether the electric heater is on (operating), etc. The operation state data on the current operation state of the controlled device is collected and stored in the ROM 11 or the RAM 12 (FIG. 2).
(See Heating Capacity, Heating Capacity,
Based on the capacity code data indicating the cooling capacity, etc., the ratio indicating the degree to which the operating state of each controlled device occupies the operating state of the entire system is determined, and processing and control for performing the charge apportionment are performed. Function to perform.

Here, the charge apportionment using the apportionment information function will be described with reference to FIGS.

FIG. 6 shows an example of the capability code data.

FIG. 6 shows the capabilities of two different types of indoor units (models A and B) and the corresponding capability code data.

Specifically, in the case of the model A, when the indoor functional capacity is 5000 kcal / h, the capability code data is "0011" in 4 bits, and in the case of the model B,
Similarly, when the indoor functional capability is 50 (W), the capability code data is "0010" in 4 bits.

Next, the collection and processing of the specific charge apportionment information for each of the above-mentioned model A and model B will be described. 1) In the case of model A First, the collection and processing of the charge apportionment information in the case of model A will be described with reference to the processing flowchart of FIG.

In the case of the model A, the communication adapters 3-1 to 3-3
Is constantly receiving the periodic communication performed between the indoor unit and the outdoor unit connected to the indoor unit, and operates data,
The required capacity level, the actual wind speed (FMi), and the device code of the indoor unit are stored in the RAM 12 (see FIG. 2) as charge apportionment information. Further, at the time of the first communication, the communication adapters 3-1 to 3-3 receive the capability code of the indoor unit in addition to the above data, and store them in the RAM 12.

Next, the communication adapters 3-1 to 3-3 detect the required capacity level and wind speed of each indoor unit (step S1),
For each indoor unit, the required capacity level is integrated in units of minutes for each wind speed (step S2). The wind speed in this case refers to a wind speed that can be set in the indoor unit, such as a sudden wind (HH), a strong wind (H), or a weak wind (L & LL).

Specifically, when the required capacity level (a value proportional to the difference between the actual room temperature and the set temperature) is 0, that is, since the actual room temperature and the set temperature are the same, the thermostat is turned off. , The wind speed is detected every minute and the operation time for each wind speed is integrated in units of one minute.
Get accumulated time data.

When the required capacity level is 1 or more, that is, when there is a difference between the actual room temperature and the set temperature, and the thermostat is on, the wind speed is detected every minute and the wind speed is detected. The required capacity level (value) at the time of detection is integrated to obtain required capacity level integrated data (step S3). More specifically, when the required capacity level at the time of a certain wind speed detection is “20” and the required capacity level at the next same wind speed detection is “15”, the required capacity level integrated data value is: 20 + 15 = 35.

Next, when the required capacity level is 1 or more (when the thermostat is on), the required capacity level integrated data is converted (converted) into second integrated time data by the following formula every hour.

Second integrated time data = required capacity level integrated data / maximum required capacity level This second integrated time data indicates that operation for a predetermined time at a certain required capacity level is as follows.
It means the number of minutes of running at the maximum required capacity level. That is, by expressing the operation state as a function of the maximum required capability level, the management of the operation state is facilitated.

In this case, as shown in FIG.
The maximum value of the required capacity level integrated data per hour is the maximum required capacity level = 30, and the timing (number of measurements) for detecting the wind speed in one hour is 60 times. Therefore, the maximum required capacity level integrated data = 30 × 60 = 1800 (level / minute). Accordingly, the maximum value of the second integrated time data (indicated by the integrated time in FIG. 8) is: maximum second integrated time data = maximum required capacity level integrated data / maximum required capacity level = 1800/30 = 60 (minutes) Becomes

As a result, the second integrated time data in the rapid wind (HH) when the thermostat is on, the second integrated time data in the strong wind (H) when the thermostat is on, and the second integrated time data in the low wind (L & LL) when the thermostat is on. Integrated time data, first integrated time data at high wind (HH) with thermostat off, first integrated time data at strong wind (H) with thermostat off, and first integrated time data at low wind (L & LL) with thermostat off Is obtained.

Next, the communication adapters 3-1 to 3-3 determine the first
The integrated time data and the second integrated time data are transferred to the main controller 2 via the main communication line LM.

As a result, the main controller 2 determines the operating state of the indoor unit based on the transferred first integrated time data and second integrated time data, and determines the usage fee (step S4).

Next, a more specific integration operation will be described with reference to FIG.

FIG. 9A shows the integration operation in the required capacity level = 0, that is, in the thermostat off state.

When the elapsed time is 0 minutes, the wind speed becomes
H) and is not counted. The setting is the same even when the elapsed time is one minute.

Therefore, at this stage, the first integrated time data of the rapid wind (HH) of the thermostat off becomes 1 (minute).

Next, the wind speed at the elapsed time of 1 minute and 30 seconds is set to a strong wind (H), but since the wind speed is not detected at this timing, this state is not collected as the first integrated time data. .

Subsequently, the wind speed when the elapsed time is 2 minutes is set to the weak wind (LL), and the first integrated time data of the thermostat-off weak wind (LL) becomes 1 (minute).

Next, when the elapsed time is 2 minutes and 40 seconds, the wind speed is set to the rapid wind (HH). However, at this timing, the wind speed is not detected, and the thermostat-off is performed when the elapsed time reaches 3 minutes. The integration of the storm (HH) is performed, and the first integration time data = 2 (minutes).

FIG. 9B shows the integration operation when the required capacity level is 1 or more, that is, when the thermostat is on.

When the elapsed time is 0 minutes, the wind speed becomes
H), the required capability level is 20, and the setting is the same even when the elapsed time is 1 minute.

Therefore, at this stage, the required capacity level integrated data of the thermostat-on rapid wind (HH) = 20.

Next, the wind speed at the elapsed time of 1 minute and 30 seconds is set to a strong wind (H). However, since the wind speed is not detected at this timing, this state is not collected as the required capability level integrated data.

Subsequently, the wind speed when the elapsed time is 2 minutes is set to the weak wind (LL), and the required level is 25. Therefore, the required performance level integrated data of the thermostat-on weak wind (LL) = It will be 25.

Next, when the elapsed time is 2 minutes and 40 seconds, the wind speed is set to the rapid wind (HH). However, at this timing, the wind speed is not detected, and when the elapsed time reaches 3 minutes, the thermostat-on is started. The storm (HH) is integrated, and the required capacity level integrated data = 30.

As described above, the required capacity level integrated data is collected. For example, the required capacity level integrated data at each wind speed one hour later is indicated by a thermostat-on storm (HH) of 46: a thermostat-on strong wind (HH). H): 1234 If the thermostat-on weak wind (L & LL): 251 is satisfied, the second integrated time data at each wind speed is: Thermostat-on rapid wind (HH): 46/30 =
2 (min) Thermostat on strong wind (H): 1234/3
0 = 41 (min) Thermostat-on weak wind (L & LL): 251/30
= 8 (minutes).

Therefore, if the total sum of the second integrated time data is obtained, it is equivalent to the number of minutes of operation when it is assumed that the indoor unit has been operated at the maximum required capacity level during one hour. That is, the operating state can be grasped based on the same standard, and the operating state can be easily compared between indoor units having different capacities. In other words, the operating state can be grasped as a function of the maximum required capacity level, which is the reference operating state data, and the comparison can be easily performed.

Therefore, even in a centralized air-conditioning system in which a plurality of indoor units having various capacities are connected, the charge apportionment can be easily performed. 2) In the case of the B model In the case of the B model, the communication adapters 3-1 to 3-3 perform the periodic communication performed with the indoor unit, and the operation data, the set wind speed, The device code of the indoor unit is stored in the RAM 12 as charge apportionment information.

Next, for each indoor unit, the time of operation at the wind speed for each wind speed is integrated in minutes. The wind speed in this case refers to a wind speed that can be set in the indoor unit, such as a sudden wind (HH), a strong wind (H), or a weak wind (L & LL).

Next, upon receiving the thermostat-on integration signal output when the integration time of the thermostat-on time reaches one hour, the thermostat-on time is determined based on the integration time for each wind speed from the start of integration. / Off time is distributed in that ratio.

More specifically, as shown in FIG. 10, the total integration time from the start of integration to the output of the thermostat-on signal = 2 hours (= 60 minutes + 30 minutes + 30)
Min) is calculated based on the integrated time ratio for each wind speed, that is, rapid wind: strong wind: weak wind = 2: 1: 1. In case of rapid wind: thermostat on time = 30 minutes In case of strong wind: thermostat on time = 15 Min. Low wind: Thermostat on time = 15 minutes can be obtained, and this is integrated for each wind speed to be used as apportionment information, and charges can be apportioned easily.

The thermostat off time is obtained by subtracting the thermostat on time from the accumulated time.

In the case of a sudden wind: 60−30 = 30 (min) In the case of a strong wind: 30−15 = 15 (min) In the case of a weak wind: 30−15 = 15 (min) FIG. Is shown.

As the apportionment data, FIG. 11 shows the user name (tenant name), the indoor unit numbers belonging to the user, and the actual indoor unit address data (=
Group code and device code), the capacity (capacity) of the indoor unit, the ratio of the electric consumption of the indoor unit to the electric consumption of the entire cooling and heating system, (electrical apportionment rate [%]),
The electricity rates based on the electricity apportionment rates corresponding to all the indoor units of the user are displayed. In this way, by assigning the apportionment information function to each of the communication adapters 3-1 to 3-3, information (data) obtained by a sensor or the like (not shown) provided in each controlled device is provided closer. Communication lines only need to be transmitted to each of the communication adapters 3-1 to 3-3, so that the communication line can be shortened, and the probability of being affected by noise or the like mixed in from power supply wiring and the like is reduced, so that more accurate data can be obtained. Collection becomes possible, and the collected data is processed in the communication adapters 3-1 to 3-3 and transmitted to the main controller as processing result data, so that the processing load on the main controller 2 can be reduced. Become.

As described above, the apportioning information for grasping the operation state of each indoor unit is managed by the communication adapters 3-1 to 3-3 arranged closer to the controlled device. Since the distance of the communication line can be shortened, it is possible to prevent noise and the like from being mixed in by the power supply line and the like, thereby preventing malfunction.

Further, the apportionment information is stored in each communication adapter 3-1.
3-3, and are transferred to the main controller 2 after pre-processing is performed. Therefore, the probability that the entire system will be down is reduced, and an independent distributed system can be constructed. 2 can be reduced.

Next, the setting function and the display function will be described again with reference to FIG.

The setting function is a function for making settings for centrally managing various functions relating to the entire cooling and heating system 1. All of the grouping setting machines for setting the controlled devices to be controlled as the same group are provided. The simultaneous operation / stop setting function for controlling the operation / stop of the controlled devices, the operation / stop setting function for individually controlling the operation / stop of each controlled device, and the operation mode of each controlled device (cooling, heating, dry , Blower, etc.), a wind speed setting function to set the wind speed (sudden, strong, weak, etc.) of each controlled device,
A flap setting function for controlling the flap direction for controlling the wind direction of each controlled device, a hand prohibition setting function, a demand setting function, a temperature setting function for setting a target temperature for each controlled device, It is composed of various functions such as a timer setting function for setting the timer operation of the control device.

As described above, various functions relating to the entire cooling / heating system 1 are centrally controlled by the main controller 2.
Side, so that costs can be reduced as compared to the case where individual devices have the same function,
This is advantageous in terms of installation area and the like.

The display function is a function for displaying the real-time operation state, various processing results, and the like on the display unit 2-2. The operation / stop display function for displaying the individual operation / stop state of each controlled device. , An operation mode display function for displaying the actual operation mode of each controlled device, a wind speed display function for displaying the wind speed of each controlled device, a flap display function for indicating the flap direction of each controlled device, and whether or not the hand is in a hand-prohibited state. Display function, demand display function, temperature display function to display the set temperature targeted by each controlled device, temperature of each part of each controlled measure, temperature display function to show actual room temperature, etc., each controlled device There is a timer display function for displaying the timer operation state of the device.

As described above, since various display functions for monitoring the entire cooling and heating system 1 are managed by the main controller 2 as in the case of the setting function,
It is possible for the administrator to easily grasp the operating state of the entire system 1 in real time.

Next, another normal operation will be described. In this case, it is assumed that the indoor units connected to the communication adapters 3-1 to 3-3 have already been grouped using the setting function described above, and the group code and the device code are assigned to each device. It is assumed that each is assigned.

First, the main controller 2 stores control data for controlling each indoor unit or outdoor unit together with an address code for specifying a communication adapter controlling the indoor unit or outdoor unit to be controlled. Output on the communication line LM.

The control data includes a controlled device address code (= group code and device code) for specifying the indoor unit or the outdoor unit to be controlled.

FIG. 12 shows an example of a control setting screen of the main controller 2.

For example, the indoor unit having the group code = 1 and the device code = 13 in the address code performs the timer operation based on the timer B, and the set temperature is 24 ° C.
The operation mode indicates dry operation, the wind speed is automatically set, and the control mode is central control second group.

On the other hand, the CPU of each of the communication adapters 3-1 to 3-3
Reference numeral 10 constantly monitors the presence or absence of data transfer from the main controller 2 via the interface unit 13 or the interface unit 13A.

Thus, each of the communication adapters 3-1 to 3-3
When the control data to which the address code indicating its own is added is transferred, only the control data is separated and the RO
The control code is analyzed based on the program and the basic data in M11, and the corresponding indoor unit or outdoor unit is controlled.

In parallel with this, the operating state of each communication adapter can be displayed in a matrix on the display section 2-2 of the main controller 2.

FIG. 13 shows an example of the operation state matrix display state of the indoor unit.

For example, to the communication adapter number = 10, the indoor unit numbers = 2 to 7, 11 are connected, and the indoor units of the indoor unit numbers = 2, 3, and 6 are in the cooling operation, the indoor unit number = 4, The indoor units 5, 7, and 11 are performing the heating operation.

By the way, each of the communication adapters 3-1 to 3-3 is
The apportionment information is managed by the apportionment information function as described above, and the operation state data obtained from each indoor unit is collected,
After processing as necessary, it is transferred to the main controller 2 via the main communication line LM.

Thus, the main controller 2 grasps the operation state of each indoor unit and each outdoor unit based on the transferred operation state data or the processed operation state data,
The control data is output via the main communication line LM as needed.

FIG. 14 shows the main controller 2 based on the accumulated operation time data obtained by the communication adapters 3-1 to 3-3 collecting the operation state data and independently processing the data.
Shows a display example in a case where a list of accumulated operation times is displayed on the display unit 2-2.

FIG. 14 shows the communication adapter 3-1 to 3-3 number = 1.
0 (for example, communication adapter 3-
This is a list of the accumulated operation time corresponding to 1), in which the indoor units of the indoor unit numbers = 1 to 8 are connected, and the name of the user (tenant) of each indoor unit, the operation time, and the operation contents (when the thermostat is on) The operation time), the capacity (capacity) of the indoor unit, and the number of power on / off times (on / off times) of each indoor unit are displayed.

The main controller 2 includes a communication adapter 3

According to the first aspect of the present invention, the management control device includes:
The terminal processing control device monitors the operation state of each controlled device, collects operation state data, integrates, converts the obtained integrated operation state data using predetermined reference operation state data,
The usage state of the controlled device is managed based on the apportioned data output by calculating the operation ratio of all the controlled devices to the operation state of the controlled device.

Therefore, even when a large number of controlled devices are installed, the use state of each controlled device can be accurately grasped as a function of the reference operating state data, and each controlled device can be grasped. It is possible to accurately grasp the usage ratio to the usage state of the entire system and to share the cost fairly.

According to the second aspect of the present invention, the terminal processing control device independently controls a group of controlled devices connected via the communication connection terminal and the sub communication line, and the central control device controls the terminal processing. The entire system including the entire controlled device is controlled via the control device and the main communication line. In addition, the terminal processing control device includes a determination unit that determines a communication connection terminal that has actually received communication data from the controlled device group side among the plurality of communication connection terminals, and a determination result of the determination unit. Control means for incorporating the controlled device group connected to the communication connection terminal that has received the communication data into its own control system, so that one terminal processing control device can control a plurality of controlled devices. Since the device group can be controlled independently, the device resources can be effectively used, and the flexibility and easiness of system construction are improved. Further, a controlled device group that does not transmit communication data to the terminal processing device side via the communication connection terminal, that is, when the controlled device group is not connected to the communication connection terminal, or is connected to the communication connection terminal. However, since the non-control device group that is in the non-operation state is not incorporated in the control system, the processing load on the terminal processing device can be reduced.
