BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized control device,
In particular, it 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, and a plurality of indoor units are connected to a main controller via a sub-controller and a communication line, and the main controller controls the entire system. There is a central heating and cooling management system in which a sub-controller provided on the user side locally controls an indoor unit connected to the sub-controller.

In such a centralized heating and cooling management system, in order to obtain the same cooling and heating capacity, the cost and the installation area etc. are 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 the individual management system,
Since the user only has to pay the electricity charge, the gas charge, etc. based on the electricity meter, the gas meter, etc. according to the usage state, it is not necessary to manage the usage state in particular.

On the other hand, in the above-mentioned centralized control 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 are differences in usage time, usage condition (for example, required cooling capacity, etc.), etc. Because of 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, the unfairness cannot be resolved because the usage time, the usage status, etc. are different for each user. was there.

Further, in the conventional centralized control system described above, only one indoor unit can be connected to each sub-controller.

Therefore, for example, even if 16 indoor units can be connected to one sub-controller, two sub-controllers need to be provided when two systems of eight indoor units are provided. Unable to effectively utilize equipment resources,
There was a problem that the cost of the entire system increased.

Therefore, a first object of the present invention is to provide a centralized control device capable of accurately grasping the usage 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 with respect to the usage state of the entire system and sharing the cost evenly.

A second object of the present invention is to simplify the configuration of the entire system even when a controlled device is installed in a plurality of systems, and to effectively utilize the device resources and to reduce the installation cost. It is to provide a centralized control device capable of reducing the noise.

[0012]

In order to solve the above-mentioned problems, a first aspect of the present invention relates to a plurality of controlled device groups each of which includes a plurality of controlled devices, and one or a plurality of the controlled device groups. Connected via a sub-communication line, monitor the operating state of each controlled device, collect and integrate operating state data, convert the obtained integrated operating state data using a predetermined reference operating state data, A terminal processing control device that obtains operation ratios of the controlled devices with respect to the operation states of all controlled devices and outputs as proportional distribution data; and a management control device that manages the operating state of the controlled devices based on the proportional distribution data. Be prepared and configured.

A second aspect of the invention is to have a plurality of controlled device groups, each of which is composed of 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 each controlled device group connected to each communication connection terminal is connected to the terminal processing device via a main communication line. And a centralized processing control device for controlling the entire system.

Further, in the third invention, in addition to the configuration of the second invention, the terminal processing control device actually receives communication data from the controlled device group side among the plurality of communication connection terminals. Discriminating means for discriminating the communication connection terminal, and 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 discrimination result of the discriminating means. And, and is configured.

[0015]

According to the first aspect of the invention, the terminal processing control device monitors the operating states of the controlled devices connected via the sub communication line, collects and integrates the operating state data, and obtains the obtained integrated data. The operating state data is converted using predetermined reference operating state data, and the operating ratio of the controlled device to the operating states of all controlled devices is obtained and output to the management control device as proportional distribution data.

As a result, the management control device manages the usage state of the controlled device based on the proportional division data that is a function of the reference operation state data.

Therefore, even when a large number of controlled devices are installed, it becomes possible to accurately grasp the usage state of each controlled device by using the proportional distribution data which is a function of the reference operating state data. At the same time, the operating ratio of each controlled device to the operating state of the entire system can be accurately grasped and the costs can be shared fairly.

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 centralized processing control device comprises: The entire system including the controlled device is controlled through the terminal processing control device and the main communication line.

Therefore, since one terminal processing control device can independently control a controlled device group of a plurality of systems, device resources can be effectively used, and flexibility and ease of system construction are improved. .

Further, according to the third invention, the discriminating means is
Of the plurality of communication connection terminals, the communication connection terminal that actually received the communication data from the controlled device group side is determined, and the control means receives the communication data based on the determination result of this determination means. The controlled device group connected to the communication connection terminal is incorporated into its own control system.

Therefore, in addition to the function of the second invention,
A controlled device group that does not transmit communication data to the terminal processing device side through 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. Since the non-control device group in the non-operating state is not incorporated in the control system, the processing load on the terminal processing control device can be reduced.

And a device group UG.

The main controller 2 has a controller main body 2-1 in which a communication control board having a configuration substantially similar to that of a communication adapter described later, a control board (not shown) for performing various controls, and the like, various setting data, and A display unit 2-2 for displaying the operating state of the control device,

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

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

The CPU 1 reads 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 the 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 controlled device group of the m-th system, that is, the first system (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 (reception data) from any of 1n is included (step S3).

If the communication data (reception data) from any of the controlled devices U11 to U1n forming the controlled device group of the first system is included in the determination in step S3, the first system Since the controlled device group of is in the operating state, the CPU controls the controlled device group of the first system,
It is incorporated into the control system (step S4). That is, the operating state is monitored based on the received data at every predetermined timing, and the control command is transmitted as communication data as necessary.

If the communication data from the controlled devices U11 to U1n forming the controlled device group of the first system is not included in the determination in step S3, the controlled device group of the first system is connected. Since it is not operating or is in a non-operating state (for example, the power is not turned on), the CPU 1 shifts the processing to the processing of step S5 and, at the same time, reads the next communication data, and the system is controlled by the control system. First of all, no control is performed.

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

When the variable m exceeds the maximum system number n in the determination in step S6, the process of incorporating the controlled device group into the control system is terminated.

If the variable m does not exceed the maximum number of systems n in the determination in step S6, the process proceeds to step S6.
3, and the processing of steps S3 to S6 is repeated.

More specifically, in the case of this embodiment, since m = 2 n = 2 at this point, the process proceeds to step S3, and the read communication data contains the data of the second system. Controller group (in this case,
It is determined whether or not the communication data (reception 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 ( Step S3).

Thereafter, in the same manner, the processes of steps S4 to S6 are performed, and the process of incorporating the controlled device group into the control system is completed.

Although the communication adapter 3-2 controls the controlled device group of two systems, the communication adapter may be configured to control the controlled device group of plural systems of three or more systems in the same manner. It is possible.

By using the communication adapter capable of controlling the controlled device group of a plurality of systems in this way, it is possible to easily and centrally control the controlled device group of the multiple systems without increasing the number of communication adapters.

Even if the number of systems of the non-control device group to be controlled increases, it is not necessary to provide the number of communication adapters in proportion to the number of systems, and the device resources can be effectively used.

Further, if one communication adapter is provided, it becomes possible to configure various connection modes of the controlled device 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 again with reference to FIG.

Although various modes of the controlled device group UG can be considered, an example thereof 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 further 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.
Is connected to the first controlled device group, and the second controlled device group to which a plurality of indoor units 20 and one outdoor unit 22 are similarly connected is connected via the second sub communication line LS22. There is.

The third communication adapter 3-3 has a sub communication line L.
A plurality of indoor / outdoor unit sets 24 in which one outdoor unit is connected to one indoor unit 20 are connected via S3, and further, via a group control communication line GL which is a control line of one remote controller 25. Multiple indoor / outdoor unit set 26
Are connected.

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

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

Of these three basic functions, the proportional distribution information function is shared as the work (processing) of the communication adapters 3-1 to 3-3, and the setting function and the display function are shared as the main controller's work (processing). ing.

The apportioning information function is operation data indicating whether each indoor unit or outdoor unit, which is a controlled device connected to one communication adapter, is in an operating / stopped 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 operating state data regarding the current operating state of the controlled device of FIG.
(Refer to), the capacity of each controlled device (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 obtained, and the processing and control for performing charge apportionment etc. are performed. This is the function to perform.

Charge apportionment using the apportionment information function will now be described with reference to FIGS. 6 to 11.

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

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

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

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

For model A, communication adapters 3-1 to 3-3
Is constantly receiving periodic communication performed between the indoor unit and an outdoor unit connected to the indoor unit,
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 proportional distribution information. Also, the communication adapters 3-1 to 3-3 receive the capability code of the indoor unit in addition to the above-mentioned data at the time of the first communication and store it in the RAM 12.

Next, the communication adapters 3-1 to 3-3 detect the required capacity level and the wind speed of each indoor unit (step S1),
For each indoor unit, the required capacity level is integrated for each wind speed in minutes (step S2). The wind speed in this case refers to a wind speed that can be set in the indoor unit, such as a rapid wind (HH), a strong wind (H), and 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, the actual room temperature and the set temperature are the same, the thermostat is in the off state. In the case of 1), the wind speed is detected every 1 minute, and the operating time for each wind speed is integrated in 1-minute units.
Obtain accumulated time data.

When the required capacity level is 1 or more, that is, when the thermostat is in the ON state because there is a difference between the actual room temperature and the set temperature, the wind speed is detected every one minute and 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 a certain wind speed detection is “20” and the required capacity level at the same next 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 in the ON state), the required capacity level integrated data is converted (converted) into the second integrated time data by the following equation every hour.

Second accumulated time data = required capacity level accumulated data / maximum required capacity level This second accumulated time data indicates that operation at a certain required capacity level for a predetermined time is performed.
It means how many minutes it takes to drive at the maximum required capacity level. That is, by expressing the operating state as a function of the maximum required capacity level, the operating state can be easily managed.

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 wind speed detection timing (measurement number) is 60 times per hour. Therefore, the maximum required capacity level integrated data = 30 × 60 = 1800 (level / minute). Therefore, the maximum value of the second integrated time data (indicated by the integrated time in FIG. 8) is the 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, the second integrated time data in the weak wind (L & LL) when the thermostat is on. Integrated time data, first integrated time data in rapid wind (HH) when the thermostat is off, first integrated time data in strong wind (H) when the thermostat is off, and first integrated time data in weak wind (L & LL) when the thermostat is off Will be obtained.

Next, the communication adapters 3-1 to 3-3 find 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 transferred integrated time data, and determines the usage charge (step S4).

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

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

When the elapsed time is 0 minutes, the wind speed is rapid (H
It is set to H) and does not count. The setting is unchanged even when the elapsed time is 1 minute.

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

Next, the wind speed at the elapsed time of 1 minute and 30 seconds is set to 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) is 1 (minute).

Next, when the elapsed time is 2 minutes and 40 seconds, the wind speed is set to rapid wind (HH), but the wind speed is not detected at this timing, and the thermostat is turned off at the stage when the elapsed time is 3 minutes. Rapid wind (HH) is integrated and the first integrated time data = 2 (minutes).

FIG. 9B shows the integrating operation in the case where the required capacity level is 1 or more, that is, in the thermostat-on state.

When the elapsed time is 0 minutes, the wind speed is rapid (H
H) is set, the required capacity level is 20, and the setting is unchanged even when the elapsed time is 1 minute.

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

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

Next, 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 capacity level integrated data of the thermostat-on weak wind (LL) = 25.

Next, when the elapsed time is 2 minutes and 40 seconds, the wind speed is set to rapid wind (HH), but the wind speed is not detected at this timing, and the thermostat is turned on at the stage when the elapsed time becomes 3 minutes. Rapid wind (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 after one hour is thermostat-on rapid wind (HH): 46 thermostat-on strong wind ( H): 1234 Thermostat on weak wind (L & LL): 251, the second accumulated 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 sum of these second integrated time data is obtained, it corresponds to how many minutes the indoor unit is operated for a certain hour assuming that the indoor unit is operating at the maximum required capacity level. That is, it is possible to grasp the operating state on the same basis, and it is possible to easily compare the operating states even 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 the centralized cooling and heating system in which a plurality of indoor units having various capacities are connected, the apportionment of charges can be easily performed. 2) In the case of B model In the case of B model, the communication adapters 3-1 to 3-3 use the regular communication with the indoor unit to perform operation data, which is reply data from the indoor unit, set wind speed, and The device code of the indoor unit is stored in the RAM 12 as charge apportionment information.

Next, the time during which each indoor unit has been operated at 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 rapid wind (HH), a strong wind (H), and a weak wind (L & LL).

Next, when the thermostat-on integration signal output when the integration time of the thermostat-on time reaches one hour is received, the thermostat-on time is calculated based on the integration time for each wind speed from the start of integration. / Distribute off-time 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) based on the cumulative time ratio for each wind speed, ie, 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 In the case of weak wind: Thermostat on time = 15 minutes, which can be obtained, and by accumulating this for each wind speed, it can be used as apportionment information to easily apportion charges.

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

In case of rapid wind: 60-30 = 30 (minutes) In case of strong wind: 30-15 = 15 (minutes) In case of weak wind: 30-15 = 15 (minutes) Fig. 11 shows an example of proportional distribution data display state Indicates.

As proportional distribution data, FIG. 11 shows a user name (tenant name), an indoor unit number belonging to the user, and actual indoor unit address data (=) corresponding to each indoor unit number.
Group code and device code), the capacity (capacity) of the indoor unit, the ratio of the amount of electricity used by the indoor unit to the amount of electricity used by the entire heating and cooling system, (electrical proportional division [%]),
The electricity charges based on the electricity apportionment rate corresponding to all the indoor units of the user are displayed. In this way, by sharing the apportioning information function among 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 in a closer position. Since it is only necessary to transmit to each of the communication adapters 3-1 to 3-3 that are provided, the communication line can be short, the probability of being affected by noise mixed in from the power supply wiring, etc. is reduced, and more accurate data can be obtained. In addition to enabling the collection, the collected data is processed by the communication adapters 3-1 to 3-3 and is transmitted to the main controller as processing result data, so that the processing load of the main controller 2 can be reduced. Become.

As described above, the proportional distribution information for grasping the operating state of each indoor unit is managed by the communication adapters 3-1 to 3-3 arranged at a position closer to the controlled device. Since the distance of the communication line can be shortened, it is possible to prevent mixing of noise due to the power supply line and the like and prevent malfunction.

Further, the apportioning information is provided in each communication adapter 3-1.
~ 3-3 It is stored in the side, pre-processed and transferred to the main controller 2 side, the probability that the entire system will go down is reduced, and a self-sustained distributed system can be constructed and the main controller The burden of 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 related to the entire cooling / heating system 1, and all grouping setting machines for setting controlled devices to be controlled as the same group. Control / stop setting function to control the operation / stop of each controlled device, operation / stop setting function to control the operation / stop of each controlled device individually, operation mode of each controlled device (cooling, heating, dry , Wind mode, etc.), operation mode setting function, wind speed setting function for each controlled device (rapid, strong, weak, etc.),
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 the temperature to be targeted by each controlled device, and 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, the various functions related to the cooling and heating system 1 as a whole are centralized in the main controller 2.
Since it is managed by the side, cost can be reduced compared to the case where each device has the same function.
It is advantageous in terms of installation area, etc.

The display function is a function for displaying a real-time operation state, various processing results, etc. on the display unit 2-2, and an operation / stop display function for displaying an individual operation / stop state of each controlled device. , The operating mode display function that displays the actual operating mode of each controlled device, the wind speed display function that displays the wind speed of each controlled device, the flap display function that shows the flap direction of each controlled device, whether it is in the forbidden state Display function to show hand prohibition, demand display function, temperature display function to display target temperature set by each controlled device, temperature display function to show temperature of each part of each controlled measure, actual room temperature, each controlled device There is a timer display function for displaying the timer operating 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 side as in the case of the setting function,
It becomes 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 above-mentioned setting function, and each device has a group code and a device code. It is assumed that each is assigned.

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

This 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 the control setting screen of the main controller 2.

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

On the other hand, the CPU of each communication adapter 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.

As a result, each communication adapter 3-1 to 3-3
When the control data with the address code indicating the self is transferred, only the control data is separated and RO
The control code is analyzed based on the program and basic data in M11, and the corresponding indoor unit or outdoor unit is controlled.

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

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

For example, the communication adapter number = 10 is connected to the indoor unit numbers = 2 to 7 and 11, 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 indicate that they are performing heating operation.

By the way, each communication adapter 3-1 to 3-3
As mentioned above, the apportionment information is managed by the apportionment information function, and the operation status 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.

According to the first invention, the management control device is
The terminal processing control device monitors the operating state of each controlled device, collects operating state data, integrates the obtained integrated operating state data, and converts the obtained integrated operating state data using predetermined reference operating state data,
The use state of the controlled device is managed based on the proportional distribution data obtained by obtaining the operation ratios of the controlled device to the operation states of all the controlled devices.

Therefore, even when a large number of controlled devices are installed, it is possible to accurately grasp the usage state of each controlled device as a function of the reference operating state data, and to control each controlled device. It becomes possible to accurately grasp the usage ratio with respect to the usage status of the entire system and to fairly share the cost.

Further, according to the second invention, the terminal processing control device independently controls the controlled device groups connected through the communication connection terminal and the sub communication line, and the centralized processing control device: Since the entire system including the entire controlled device is controlled via the terminal processing control device and the main communication line, it is possible to independently control a controlled device group of a plurality of systems by one terminal processing control device. The device resources can be effectively used without wasting the processing capacity of the processing control device. Furthermore, various connection modes of the controlled device group to the terminal processing control device can be adopted, and flexibility and ease of system construction are improved.

Further, according to the third invention, the discrimination means is
Of the plurality of communication connection terminals, the communication connection terminal that actually received the communication data from the controlled device group side is determined, and the control means receives the communication data based on the determination result of this determination means. Since the controlled device group connected to the communication connection terminal is incorporated in its own control system, the controlled device group that does not transmit communication data to the terminal processing device side through the communication connection terminal, that is, the communication connection terminal When the controlled device group is not connected to, or because the non-controlled device group that is connected to the communication connection terminal but is in the non-operating state due to the power not being turned on is not incorporated in the control system,
The processing load on the terminal processing control device due to unnecessary processing can be reduced, the processing speed can be increased, and a system with good responsiveness can be constructed.
