On the other hand, when the sleep time notification is not received (step S21; NO), the control unit 11 proceeds to the process of step S23 without performing the process of step S22.

In step S23, the control unit 21 determines whether or not a measurement data request has been received from the integrated controller 10. When the measurement data request is received (step S23; YES), in the subsequent step S24, the control unit 21 transmits a measurement data response storing the measurement data stored in the storage unit 22 to the integrated controller 10. The process proceeds to step S25. On the other hand, when determining that the measurement data request has not been received (step S23; NO), the control unit 21 proceeds to the process of step S25 without performing the process of step S24.

In step S25, the control unit 21 determines whether or not a measurement data notification is received from the corresponding sensor device 30. When the measurement data notification is received (step S25; YES), in the subsequent step S26, the control unit 21 stores (saves) the measurement data included in the received measurement data notification in the storage unit 22, and performs the process of step S27. Proceed to On the other hand, when the measurement data notification is not received (step S25; NO), the control unit 21 ends this process.

In step S27, the control unit 21 determines whether or not the sleep time notification reception flag is ON. When the sleep time reception notification flag is not ON (step S27; NO), the control unit 21 ends this process.

Specifically, the control unit 31 makes the above determination based on whether or not a notification that a preset time has elapsed from the time management unit 33 has been received. As a result, when the predetermined time has not elapsed (step S32; NO), the control unit 31 proceeds to the process of step S33.

In step S33, the control unit 31 determines whether or not a sleep time setting request from the corresponding wireless master device 20 has been received. When the sleep time setting request is received (step S33; YES), the control unit 31 updates the sleep time stored in the storage unit 32 based on the received sleep time setting request (step S34). Then, the control part 31 returns to the process of step S32. On the other hand, when the sleep time setting request has not been received (step S33; NO), the control unit 31 returns to the process of step S32 without executing the process of step S34.

When a predetermined time has elapsed since the start of time measurement (step S32; YES), the control unit 31 prohibits reception of data in the sensor device 30 (step S35). Further, the control unit 31 executes sleep execution and release processing (step S36).

In the initial state, it is assumed that the operation of the facility device 40 is stopped.

First, the control unit 43 of the communication unit 41 acquires the current operating state of the equipment 40 from the main control unit 42 (step S51). And the control part 43 detects the change of a driving | running state by comparing the acquired driving | running state with the driving | running state acquired last time.

When the driving state has changed from the stop state to the driving state (step S52; YES), the control unit 43 generates data (state change notification) storing information indicating that the driving state is in progress, and the generated state A change notification is transmitted to the integrated controller 10 via the communication I / F unit 45 (step S53), and this process ends.

On the other hand, when the operation state has changed from operation to stop (step S54; YES), the control unit 43 transmits a state change notification storing information indicating that the operation is stopped to the integrated controller 10 ( Step S55), the process is terminated.

If the operating state has not changed, the control unit 43 ends this processing without transmitting a state change notification to the integrated controller 10. Note that the data indicating the operation state acquired this time is stored in the storage unit 44.

FIG. 11 is a diagram illustrating a communication sequence of the measurement system 1 according to the present embodiment. It is assumed that the facility device 40 has already started operation at the start of this communication sequence. Further, it is assumed that the time T2 is set as the sleep time of the sensor device 30 corresponding to the facility device 40.

In the communication sequence of FIG. 11, each time the sensor device 30 wakes up from the sleep state, it acquires measurement data (see step S44 of FIG. 9) and notifies the measurement data including the measurement data (data D11 to D14). Is transmitted to the corresponding wireless master device 20 (see step S45 in FIG. 9).

Hereinafter, the sleep control of the sensor device 30 and the control of the facility device 40 will be specifically described with reference to the communication sequence example of FIG.

First, sleep control of the sensor device 30 when the equipment device 40 is in operation will be described.

When the sensor device 30 transmits the measurement data notification (data D11), the sensor device 30 is in a reception-permitted state for the time T1 (the time set in the time management unit 33) (see steps S32 and S33 in FIG. 8 and step S46 in FIG. 9). ). After that, when the time T1 elapses, the reception prohibited state and the sleep state are entered for the time T2 (set sleep time) (see step S35 in FIG. 8 and steps S41 and S42 in FIG. 9).

Next, control of the equipment device 40 based on the measurement data acquired by the sensor device 30 will be described.

The integrated controller 10 selects the wireless master that sequentially selects the measurement data requests (data D31 to D34) from all the wireless master devices 20 every time T4 (time set in the first timer of the time management unit 13) elapses. It transmits to the machine 20 (see step S14 in FIG. 6).

Upon receiving the measurement data requests (data D31 to D34) from the integrated controller 10, each wireless master device 20 transmits measurement data responses (data D41 to D44) to the integrated controller 10 (see step S24 in FIG. 7). . The measurement data response includes measurement data received from the corresponding sensor device 30 (see steps S25 and S26 in FIG. 7).

When the integrated controller 10 receives the measurement data responses (data D41 to D44) from each wireless master device 20, the integrated controller 10 receives the measurement data responses included in each measurement data response and each equipment device 40 corresponding to each wireless master device 20 receives the measurement data responses. Generate control information. Then, the integrated controller 10 transmits control information notifications (data D61 to D64) including the generated control information to each facility device 40 (see step S18 in FIG. 6).

When each facility device 40 receives the control information notification (data D61 to D64) from the integrated controller 10, it performs an operation based on the control information included in the notification.

Next, sleep control of the sensor device 30 when the equipment device 40 is stopped will be described.

When the facility device 40 stops operation, the facility device 40 transmits a state change notification (data D71) including information on the operation stop to the integrated controller 10 (see step S55 in FIG. 10).

When the integrated controller 10 receives the state change notification (data D71) from the facility device 40, the integrated controller 10 determines the sleep time (time T3) based on the operating state (stopped) after the change of the facility device 40. Then, the sleep time notification (data D51) including the time T3 is transmitted to the wireless master device 20 corresponding to the facility device 40 (see step S12 in FIG. 6). Here, time T3 is longer than time T2.

When receiving the sleep time notification (data D51) from the integrated controller 10, the wireless master device 20 transmits a sleep time setting request (data D21) including a request for setting the sleep time to the time T3 to the corresponding sensor device 30. (See step S28 in FIG. 7). The sleep time setting request (data D21) is transmitted immediately after the measurement data notification (data D12) is received from the wake-up sensor device 30 (before the time T1 has elapsed). Therefore, at that time, the sensor device 30 is in a reception-permitted state (see steps S25 to S28 in FIG. 7 and steps S43 to S46 in FIG. 9).

Upon receiving the sleep time setting request (data D21) from the wireless master device 20, the sensor device 30 sets the sleep time (T3) based on the sleep time setting request (see step S34 in FIG. 8) and sets it. The sleep state is entered according to the sleep time (see steps S41 and S42 in FIG. 9). That is, in this example, when the equipment device 40 is stopped, the corresponding sensor device 30 has a sleep time (time T3) longer than the sleep time (time T2) when the equipment device 40 is operating. Go to sleep.

Further, after that, before the facility device 40 starts operation again, the corresponding sensor device 30 wakes up (see step S43 in FIG. 9) and immediately acquires measurement data (see step S44 in FIG. 9). ), The measurement data notification (data D13) is transmitted to the corresponding wireless master device 20 (see step S45 in FIG. 9). And when time T1 passes after it will be in a reception permission state, said sensor apparatus 30 will be in a sleep state only for time T3 again.

Next, sleep control of the sensor device 30 when the facility device 40 starts operation again will be described.

When the facility device 40 starts operation, the facility device 40 transmits a state change notification (data D72) including information on the operation start to the integrated controller 10 (see step S53 in FIG. 10).

When the integrated controller 10 receives the state change notification (data D72) from the facility device 40, the integrated controller 10 determines the sleep time (time T2) based on the changed operation state (during operation) of the facility device 40. Then, a sleep time notification (data D52) including time T2 is transmitted to the wireless master device 20 corresponding to the facility device 40 (see step S12 in FIG. 6).

When receiving the sleep time notification (data D52) from the integrated controller 10, the wireless master device 20 transmits a sleep time setting request (data D22) including a request for setting the sleep time to the time T2 to the corresponding sensor device 30. (See step S28 in FIG. 7). The transmission of the sleep time setting request (data D22) is performed immediately after the measurement data notification (data D14) is received from the wake-up sensor device 30 (before the time T1 has elapsed). Therefore, at that time, the sensor device 30 is in a reception-permitted state (see steps S25 to S28 in FIG. 7 and steps S43 to S46 in FIG. 9).

Upon receiving the sleep time setting request (data D22) from the wireless master device 20, the sensor device 30 sets the sleep time (T2) based on the sleep time setting request (see step S34 in FIG. 8) and sets it. The sleep state is entered according to the sleep time (see steps S41 and S42 in FIG. 9). That is, in this example, when the equipment device 40 is in operation, the corresponding sensor device 30 sleeps in a sleep time (time T2) shorter than the sleep time (time T3) when the equipment device 40 is stopped. It becomes a state.

As described above, the measurement system 1 according to the present embodiment includes the sensor device 30 that measures values (for example, temperature and humidity) related to the current environment of the target space (for example, the indoor space of a building), and the sensor device 30. And an integrated controller 10 that controls the facility device 40 based on the measured value relating to the environment. When the operation state (running or stopped) of the own device changes, the facility device 40 notifies the integrated controller 10 to that effect. Upon receiving such notification, the integrated controller 10 determines the sleep time of the sensor device 30 corresponding to the facility device 40 based on the changed operating state of the facility device 40. Then, the sensor device 30 puts its own device into the sleep state according to the determined sleep time.

More specifically, the integrated controller 10 sets the sleep time of the corresponding sensor device 30 to be longer than the normal sleep time when the equipment device 40 is stopped. Normally, in the equipment device 40, when the operation state is stopped, the possibility of requiring the measurement data of the corresponding sensor device 30 is lower than that during operation. Therefore, according to the measurement system 1 of the present embodiment, the battery consumption of the sensor device 30 can be suppressed without hindering the operation (operation) of the facility device 40. For example, in the time zone when the facility device 40 is not in operation, such as at night, the total time during which the sensor device 30 does not perform measurement and communication operations increases. It becomes possible.

Further, in the measurement system 1 of the present embodiment, immediately after the sensor device 30 wakes up from the sleep state, the determined sleep time is notified to the sensor device 30 to the integrated controller 10. For this reason, the possibility of receiving the sleep time notification in the sensor device 30 increases. Therefore, it is possible to notify the sleep time efficiently.

In the measurement system 1 of the present embodiment, the control unit 31 of the sensor device 30 repeatedly executes sleep at predetermined intervals. Thereby, as a general rule, sleep is periodically executed, energy consumption is more reliably reduced, and consequently, consumption of the battery of the sensor device 30 can be suppressed.

In the measurement system 1 of the present embodiment, in the equipment 40, the control unit 43 periodically acquires the operating state from the main control unit 42, determines whether or not there is a change, and if there is a change, Immediately, a state change notification storing information indicating operation start or operation stop is transmitted to the integrated controller 10. Therefore, the integrated controller 10 can immediately grasp the equipment device 40 whose operating state has changed and its contents.

(Embodiment 2)
The second embodiment of the present invention will be described focusing on the differences from the first embodiment. In addition, about the component etc. which are common in Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted or simplified.

The measurement system according to the present embodiment also has basically the same configuration as the measurement system 1 according to the first embodiment (see FIGS. 1 to 5), and executes the processes shown in FIGS. However, in the measurement system according to the present embodiment, each of the facility devices 40 executes the process shown in FIG. 12 instead of the process shown in FIG.

First, the control unit 43 of the communication unit 41 acquires the current operating state of the equipment 40 from the main control unit 42 (step S61). And the control part 43 judges whether there was any change in the driving | running state by comparing the acquired driving | running state with the driving | running state acquired last time.

For example, in the air conditioner, the cooling operation is started in a state where the difference between the current air temperature (the temperature measured by the sensor device 30) and the set temperature is large, and then the operation is changed to the operation for maintaining the current air temperature. There are many cases. In the measurement system of the present embodiment, it is determined that the operating state of the equipment 40 has changed even in such a case.

That is, in the present embodiment, the operation state acquired by the control unit 43 includes not only during operation and stop, but also, for example, operation type (heating / cooling / air blowing, etc.), control target values (set temperature, set humidity, etc.) ), Operation mode (normal operation mode / energy saving mode, etc.).

In addition, the control part 43 may detect the change of the above driving | running states based on the output value of the sensor which is not shown in the said equipment 40. The sensor in this case measures, for example, the internal temperature, the amount of power consumption, the number of revolutions of the motor, the amount of exhaust, etc. in the equipment 40.

When the control unit 43 determines that the operation state of the equipment device 40 has changed (step S62; YES), the control unit 43 sends a state change notification storing information indicating the changed operation state to the communication I / F unit. 45 to the integrated controller 10 (step S63), and this process ends.

On the other hand, when the operation state has not changed, the control unit 43 ends this process without transmitting a state change notification to the integrated controller 10. Note that the data indicating the operation state acquired this time is stored in the storage unit 44.

FIG. 13 is a diagram illustrating a communication sequence of the measurement system according to the present embodiment. It is assumed that the facility device 40 has already started operation at the start of this communication sequence. Also, it is assumed that the time T11 is set as the sleep time of the sensor device 30 corresponding to the facility device 40.

In the communication sequence of FIG. 13, each time the sensor device 30 wakes up from the sleep state, it acquires measurement data (see step S44 of FIG. 9), and measurement data notification including the measurement data (data D11 to D14). Is transmitted to the corresponding wireless master device 20 (see step S45 in FIG. 9).

Hereinafter, the sleep control of the sensor device 30 and the control of the facility device 40 will be described in detail using the communication sequence example of FIG.

First, sleep control of the sensor device 30 when the equipment device 40 is in the first operation state will be described. In this example, the operation state in which the facility device 40 (for example, the air conditioner) performs the cooling operation in a state where the difference between the current air temperature and the set temperature is large is defined as the first operation state.

When the sensor device 30 transmits the measurement data notification (data D11), the sensor device 30 is in a reception-permitted state for a time T1 (see steps S32 and S33 in FIG. 8 and step S46 in FIG. 9). Thereafter, when the time T1 elapses, the reception prohibited state and the sleep state are entered for the time T11 (the set sleep time) (see step S35 in FIG. 8 and steps S41 and S42 in FIG. 9).

Since the control of the facility device 40 based on the measurement data acquired by the sensor device 30 is the same as that of the first embodiment, the description thereof is omitted.

Next, sleep control of the sensor device 30 when the operation state of the equipment device 40 is changed from the first operation state to the second operation state will be described. In this example, the operation state in which the facility device 40 (for example, the air conditioner) performs the cooling operation in a state where the difference between the current air temperature and the set temperature is small is set as the second operation state.

When the operation state of the equipment device 40 changes from the first operation state to the second operation state, the equipment device 40 integrates a state change notification (data D71) including information indicating the changed operation state (second operation state). The data is transmitted to the controller 10 (see step S63 in FIG. 12).

When the integrated controller 10 receives the state change notification (data D71) from the facility device 40, the integrated controller 10 determines the sleep time (time T12) based on the operation state after the change of the facility device 40 (second operation state). Then, the sleep time notification (data D51) including the time T12 is transmitted to the wireless master device 20 corresponding to the facility device 40 (see step S12 in FIG. 6). In the present embodiment, when the sleep time (for example, time T12) is determined, the sleep time is shortened as the power consumption (energy consumption) of the facility device 40 increases. For example, when the cooling operation is started in a state where the difference between the current air temperature and the set temperature is large, the sleep time is shortened as the difference between the current air temperature and the set temperature is large. That is, in this example, the time T12 is longer than the time T11.

Upon receiving the sleep time notification (data D51) from the integrated controller 10, the wireless master device 20 transmits a sleep time setting request (data D21) including a request for setting the sleep time to the time T12 to the corresponding sensor device 30. (See step S28 in FIG. 7). The sleep time setting request (data D21) is transmitted immediately after the measurement data notification (data D12) is received from the wake-up sensor device 30 (before the time T1 has elapsed). Therefore, at that time, the sensor device 30 is in a reception-permitted state (see steps S25 to S28 in FIG. 7 and steps S43 to S46 in FIG. 9).

Upon receiving the sleep time setting request (data D21) from the wireless master device 20, the sensor device 30 sets the sleep time (T12) based on the sleep time setting request (see step S34 in FIG. 8) and sets it. The sleep state is entered according to the sleep time (see steps S41 and S42 in FIG. 9). That is, in this example, when the equipment device 40 is in the second operation state, the corresponding sensor device 30 has a sleep time (time T11) longer than the sleep time (time T11) when the equipment device 40 is in the first operation state. The sleep state is entered at time T12).

Further, before that, before the operating state of the equipment device 40 changes, the corresponding sensor device 30 wakes up (see step S43 in FIG. 9) and acquires measurement data (see step S44 in FIG. 9). Then, the measurement data notification (data D13) is transmitted to the corresponding wireless master device 20 (see step S45 in FIG. 9). And when time T1 of a reception permission state passes, said sensor apparatus 30 will be in a sleep state only for time T12.

Next, sleep control of the sensor device 30 when the operation state of the equipment device 40 is changed from the second operation state to the third operation state will be described. In this example, the operation state in which the facility device 40 (for example, the air conditioner) is performing the cooling operation in a state where the current air temperature and the set temperature coincide with each other is set as the third operation state.

When the operation state of the facility device 40 changes from the second operation state to the third operation state, the facility device 40 integrates a state change notification (data D72) including information indicating the changed operation state (third operation state). The data is transmitted to the controller 10 (see step S63 in FIG. 12).

When the integrated controller 10 receives the state change notification (data D72) from the facility device 40, the integrated controller 10 determines the sleep time (time T13) based on the changed operation state (third operation state) of the facility device 40. Then, the sleep time notification (data D52) including the time T13 is transmitted to the wireless master device 20 corresponding to the facility device 40 (see step S12 in FIG. 6).

When receiving the sleep time notification (data D52) from the integrated controller 10, the wireless master device 20 transmits a sleep time setting request (data D22) including a request to set the sleep time to the time T13 to the corresponding sensor device 30. (See step S28 in FIG. 7). The transmission of the sleep time setting request (data D22) is performed immediately after the measurement data notification (data D14) is received from the wake-up sensor device 30 (before the time T1 has elapsed). Therefore, at that time, the sensor device 30 is in a reception-permitted state (see steps S25 to S28 in FIG. 7 and steps S43 to S46 in FIG. 9).

Upon receiving the sleep time setting request (data D22) from the wireless master device 20, the sensor device 30 sets the sleep time (T13) based on the sleep time setting request (see step S34 in FIG. 8) and sets it. The sleep state is entered according to the sleep time (see steps S41 and S42 in FIG. 9). That is, in this example, when the equipment device 40 is in the third operating state, the corresponding sensor device 30 has a sleep time (time T12) longer than the sleep time (time T12) when the equipment device 40 is in the second operating state. The sleep state is entered at time T13).

As described above, according to the measurement system of the present embodiment, the sleep time of the sensor device 30 can be set stepwise according to the operating state of the facility device 40 to suppress battery consumption of the sensor device 30. it can. In particular, in the measurement system of the present embodiment, the sleep time is updated when the operation of the equipment 40 is not started or stopped, and the operation state is changed even when the operation is in progress. For this reason, it becomes possible to set an appropriate sleep time more precisely according to the operating state of the equipment 40 (for example, an air conditioner).

In the measurement system of the present embodiment, the sleep time of the sensor device 30 is shortened as the operation state where the facility device 40 greatly changes the value related to the environment of the target space (as a result, the larger the energy consumption or the operation load). it can. For this reason, it is possible to set an appropriate sleep time according to the operating state of the facility device 40, and it is possible to more appropriately suppress battery consumption of the sensor device 30.

Of course, in the measurement system of this embodiment, the same effect as that of the first embodiment can be obtained.

Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, in the sensor device 30, the timing at which the control unit 31 acquires the measurement value from the sensor unit 35 is not limited. For example, in the non-sleep state, the control unit 31 may acquire measurement values from the sensor unit 35 at a predetermined cycle. In this case, immediately after waking up, the control unit 31 may read the measurement data stored in the storage unit 32 before going to sleep, and may transmit a measurement data notification including the measurement data to the corresponding wireless master device 20. .

In each of the above embodiments, the state change notification is transmitted directly from the facility device 40 to the integrated controller 10, but the state change is indirectly (from another device) to the integrated controller 10 from the facility device 40. A notification may be sent.

Further, the control information notification may be transmitted from the integrated controller 10 indirectly to the facility device 40 (via another device).

Further, the measurement system 1 in the first embodiment or the measurement system in the second embodiment may include a plurality of integrated controllers 10.

Further, by absorbing the function of the wireless master device 20 into the integrated controller 10, for example, as shown in FIG. 14, the wireless master device 20 may be removed from the configuration of the measurement system. In the configuration shown in FIG. 14, unlike the above embodiments, the integrated controller 10 is connected to each of the sensor devices 30 via the communication line L2. In this case, the integrated controller 10 directly transmits data for notifying the sleep time to the sensor device 30 (sleep time notification). Further, the integrated controller 10 directly transmits data for requesting measurement data (measurement data request) to the sensor device 30. In response to this, the sensor device 30 directly transmits data storing measurement data (measurement data response) to the integrated controller 10.

In the configuration shown in FIG. 14, the integrated controller 10 may transmit a sleep time notification to the sensor device 30 that transmitted the measurement data response immediately after receiving the measurement data response. . In this way, since the sleep time notification is transmitted to the sensor device 30 immediately after wake-up, the possibility of receiving the sleep time notification in the sensor device 30 is increased. Therefore, it is possible to notify the sleep time efficiently.

Further, as shown in FIG. 15, the measurement system may include m sensors 50_1 to 50_m. Hereinafter, when each of the sensors 50_1 to 50_m is not particularly distinguished, it is referred to as a sensor 50.

In the measurement system shown in FIG. 15, each sensor 50 is a sensor for acquiring the operating state of the corresponding equipment device 40. That is, the sensor 50 functions as an operation state acquisition device or an operation state acquisition unit. The sensor 50 measures, for example, power consumption of the corresponding equipment device 40, illuminance, temperature, humidity, air volume, and the like in the target space of the corresponding equipment device 40. The integrated controller 10 is connected to each of the sensors 50 via a communication line L5. Each sensor 50 transmits a measurement value to the integrated controller 10. The integrated controller 10 monitors the measurement value of the sensor 50 as the operation state of the facility device 40 corresponding to the sensor 50. And if the change of the driving | running state of the equipment device 40 is detected, sleep time will be determined according to the driving | running state after a change, and the determined sleep time will be transmitted to the sensor apparatus 30 corresponding to the said equipment device 40 via the wireless main | base station 20. To notify.

With the configuration shown in FIG. 15, the facility device 40 does not need to have a function of detecting a change in the operating state and notifying the integrated controller 10 when it is detected.

The sleep interval (in other words, the duration of the non-sleep state, specifically, the time set in the time management unit 33 of the sensor device 30) may be determined based on the operating state of the facility device 40. . In this case, for example, when the operation state of the facility device 40 is in operation, a long time (first sleep interval) is set as the sleep interval. On the other hand, when it is stopped, the time is shorter than the first sleep interval (second sleep interval). Interval) can be set. Alternatively, the longer the power consumption (energy consumption) of the facility device 40, the longer the sleep interval can be set.

Even in this case, the consumption of the battery of the sensor device 30 can be suppressed without impeding the operation (operation) of the facility device 40. Furthermore, when the sleep interval and the sleep time are used in combination, it is possible to more appropriately suppress battery consumption of the sensor device.

Further, in each of the above embodiments, a wired communication device is used instead of the wireless master device 20 so that the communication device and the corresponding sensor device 30 are communicably connected via a communication line. May be.

Further, the integrated controller 10 and the wireless master device 20 and the integrated controller 10 and the facility device 40 may be connected so as to be able to communicate wirelessly by a wireless LAN or the like.

Moreover, the equipment 40 is not limited to an air conditioner, and may be any device that adjusts the environment of the target space. The environment referred to here includes, for example, air cleanliness, airflow, brightness (illuminance) and the like in addition to the temperature and humidity of the air. That is, the equipment 40 may be, for example, a blower that adjusts the airflow in the target space, a lighting device that adjusts the brightness (illuminance) of the target space, and the like.

The sensor device 30 is not limited to the temperature / humidity sensor module, and may be any device that measures values related to the environment adjusted by the facility device 40. For example, when the equipment device 40 is a blower, the sensor device 30 may be a device that measures the wind direction or the air volume. Further, when the facility device 40 is a lighting device, the sensor device 30 may be a device that measures illuminance.

In each of the above embodiments, the communication format of each communication is arbitrary. For example, a text format using XML (Extensible Markup Language) or the like may be used, or another format such as a binary format may be used to reduce the communication size. Moreover, you may encrypt communication so that communication information may be concealed.

In each of the above embodiments, any storage device can be used as a storage device that holds data or a program. In addition to ROM and flash memory, for example, a magnetic storage device (hard disk drive, magnetic card, Magnetic tape or the like) or an optical disk may be used, or other storage device may be used. It is preferable to select an optimal storage device according to the application and the like.

In each of the above embodiments, the function of the integrated controller 10 may be realized by a general-purpose computer system (for example, a personal computer).

In each of the above-described embodiments, each program executed by the integrated controller 10, the wireless master device 20, the sensor device 30, or the facility device 40 is a flexible disk, a CD-ROM (Compact Disc Read Only Memory), a DVD (Digital Versatile Disc). ), MO (Magneto-Optical disk), etc., can be stored in a computer-readable recording medium and distributed. Then, by installing each program on a specific or general-purpose computer, each computer can function as the integrated controller 10, the wireless master device 20, the sensor device 30, and the facility device 40 in each of the above embodiments. Is possible.

Further, the above program may be stored in a disk device or the like included in a server device on a communication network such as the Internet, and may be downloaded onto a computer, for example, superimposed on a carrier wave. The above-described processing can also be achieved by starting and executing a program while transferring it via a communication network. Furthermore, the above-described processing can also be achieved by executing all or part of the program on the server device and executing the program while the computer transmits and receives information regarding the processing via the communication network.
