  By the way, in the illumination monitoring system which transfers the sensing data obtained by the sensor to the cloud via the slave unit and the master unit, data reliability and communication cost concerning transmission of the sensing data from the sensor to the cloud become a problem. Specific low power wireless communication such as sub giga band (for example, 920 MHz band) is used between the master and slave, and wireless communication such as 3G and 4G may be used between the master and the cloud. Wireless communication in the sub-giga band has an advantage of having a long reach, a high diffraction property, and being less susceptible to radio interference as compared with other wireless communication in the 2.4 GHz band and the like. Therefore, in recent years, the sensing technology by the above sub-giga band, such as LoRa and SIGFOX, has become widespread. On the other hand, sub-giga band radio communication has restrictions such as radio communication restriction (for example, 10%, that is, 6 minutes per hour) according to the Radio Law. In addition, there is a restriction that the communication speed is slow and the amount of data transfer is small compared to other wireless communications. Due to such restriction in wireless communication between the parent device and the child device, an interval occurs in the transmission of sensing data, and a loss of sensing data may occur. As a result, there is a problem that the reliability of sensing data finally obtained in the cloud decreases. In addition, when a large number of sensors are connected to the slave unit, the amount of data communication from the slave unit to the master unit increases, which causes a problem that not only the communication speed decreases but also the communication cost increases. Furthermore, due to the frequent transfer of sensing data from the parent device to the cloud, there have been cases in which problems such as an increase in communication cost and an increase in the possibility of data loss have occurred.

1 is a block diagram of a lighting monitoring system according to a first embodiment. FIG. 5 is a block diagram of a lighting monitoring system according to a second embodiment. FIG. 7 is a block diagram of a lighting monitoring system according to a third embodiment.

First Embodiment
FIG. 1 shows a block diagram of the illumination monitoring system 1 according to the present embodiment. The illumination monitoring system 1 includes a master unit 2, slave units 3-1 to 3-3 m, sensors 4-1 to 4-n connected to respective slave units (sub-unit 3-1 in FIG. 1), a cloud server 5 and A terminal 6 is provided. In addition, the control device 7 may be connected to the parent device 2 as needed. In the following description, handsets 3-1 to 3-m are collectively referred to or representative of any one and will be referred to as handset 3. Sensors 4-1 to 4-n are collectively referred to or any one To represent the sensor 4. Although each slave 3 has a similar configuration, the number and type of sensors 4 connected to each slave 3 may be the same or different. Each child device 3 is arranged, for example, corresponding to a not-shown light fixture or a light fixture group. Each sensor 4 has substantially the same configuration except for differences in detection targets, and is installed for a luminaire in which the corresponding slave 3 is disposed. The cloud server 5 exists on a cloud C such as the Internet. In the present embodiment, one parent device 2 is associated with the cloud server 5, but a plurality of parent devices 2 may be associated with the cloud server 5.

  As an outline, in normal operation, the sensor 4 generates sensing data based on detection data (for example, measurement data related to a lighting fixture), the slave 3 transmits sensing data to the master 2, and the master 2 senses data Are transmitted to the cloud server 5 at predetermined transmission intervals. Then, the terminal 6 can access the cloud server 5 and monitor sensing data on the cloud C. The master unit 2 and each slave unit 3 are wirelessly connected, and the slave unit 3 and the sensor 4 may be integrated on the same substrate, or may be configured on another substrate and wired or wirelessly connected. . In the present embodiment, the wireless connection between the master unit 2 and the slave unit 3 is a specified low-power radio using a sub-giga band (for example, 920 MHz band), but Wi-SUN, ZigBee (registered trademark), BLE, etc. It may be by other wireless communication conforming to the communication standard of The parent device 2 and the cloud server 5 are wirelessly connected by, for example, 3G, 4G (LTE) or the like, and the parent device 2 and the control device 7 are wired connected by a LAN or the like. The cloud server 5 and the terminal 6 are connected by wire or wirelessly via any communication method.

  The base unit 2 includes a wireless communication unit 20, a CPU 21, a memory 22, and a transmission / reception unit 23. These units are connected in such a manner that they can exchange signals and data with one another via a bus. The wireless communication unit 20 is a wireless module that performs wireless communication with each handset 3 (wireless communication unit 30). The CPU 21 includes a communication control unit 24. It is assumed that the CPU 21 can execute not only the functions of the communication control unit 24 but also general functions (such as generation of a light control signal to the child device 3) as a parent device CPU not particularly described. The memory 22 is a storage unit such as a RAM, a ROM, etc., which stores programs and data, and it is assumed that a program for executing the present embodiment has already been written. The CPU 21 and the memory 22 can be included in one microcomputer. The transmission / reception unit 23 is a communication unit capable of wireless communication with the cloud server 5 (the transceiver 50), and also has a wired communication function with the control device 7 (transmission / reception unit 70) as needed.

  The communication control unit 24 controls transmission of sensing data received from the slave 3 via the wireless communication unit 20 to the cloud server 5. The communication control unit 24 stores sensing data in the memory 22 and transmits the stored sensing data from the transmitting / receiving unit 23 to the cloud server 5 at a predetermined transmission timing. Thus, the memory 22 functions as a buffer. That is, the communication control unit 24 is configured to collectively transfer the sensing data accumulated in the buffer to the cloud server 5 instead of sequentially transmitting the sensing data received from the slave 3 to the cloud server 5. . As a result, the number of times of communication is reduced and the possibility of data loss is reduced as compared with the configuration in which the sensing data is sequentially transmitted from the parent device 2 to the cloud server 5.

  The predetermined transmission timing described above may be defined by a fixed cycle (that is, the transmission interval may be set to be constant), or the sensing data stored in the memory 22 reaches a predetermined amount. (That is, the amount of one data communication may be set to be constant). Further, the communication control unit 24 causes the wireless communication unit 20 to transmit a setting change command received from the cloud server 5 via the transmission / reception unit 23 to the handset 3. The setting change instruction will be described later.

  The slave 3 includes a wireless communication unit 30, a CPU 31, a memory 32, and an input / output interface (I / F) 33. These units are connected in such a manner that they can exchange signals and data with one another via a bus. The wireless communication unit 30 is a wireless module that performs wireless communication with the parent device 2 (wireless communication unit 20). The CPU 31 includes a communication control unit 34 and a filter unit 35. The CPU 31 is capable of executing general functions (such as illumination control of a lighting fixture not shown) as a child machine CPU not particularly specified, such as general control thereof, in addition to the functions of the communication control unit 34 and the filter unit 35 I assume. The memory 32 is a storage unit such as a RAM, a ROM, etc., which stores programs and data, and it is assumed that a program for executing the present embodiment has already been written. The CPU 31 and the memory 32 can be included in one microcomputer. The input / output I / F 33 is an interface for inputting data from the sensor 4 (input / output I / F 43) and outputting a command to the sensor 4 (input / output I / F 43).

  The communication control unit 34 causes the wireless communication unit 30 to transmit sensing data input from the sensor 4 via the input / output I / F 33 from the wireless communication unit 30 to the base unit 2 in accordance with the communication restriction of wireless communication between the base unit 3 and the base unit 2. . For example, when the communication time is limited, the input sensing data is temporarily stored in the memory 32, and the wireless communication unit 30 is operated at a predetermined time. Further, the setting change command received from the base unit 2 via the wireless communication unit 30 can be output from the input / output I / F 33 to the sensor 4. The setting change instruction will be described later.

  The filter unit 35 filters the sensing data input from the sensor 4 via the input / output I / F 33 for a predetermined period. By this filtering, the data amount of sensing data transmitted from the child device 3 to the base device 2 (and as a result, from the base device 2 to the cloud server 5) decreases.

  The filtering is, for example, a process for selecting sensing data from a predetermined sensor 4 among sensing data collected from the sensors 4-1 to 4-n (hereinafter referred to as "sensor selection process") Good. For example, when the sensors 4-1 to 4-n are sensors that detect physical quantities of different types or the same type, sensing data from some of the sensors 4 with high priority among the sensors 4-1 to 4-n are detected. It may be selected and transmitted to the master 2 as sensing data after filtering. For example, in filtering, when the priority of sensing data related to temperature is high, sensing data from the temperature sensor connected to each of the slaves 3-1 to 3-m is prioritized (or sensing from the temperature sensor) Only data) is sent to base unit 2.

  The filtering may be processing for extracting or calculating significant sensing data from the same type of sensing data collected from the sensors 4-1 to 4-n (hereinafter referred to as “tabulation processing”). For example, when the sensors 4-1 to 4-n are sensors that detect physical quantities of the same type, the average value, the maximum value, the minimum value, the median value, etc. of n sensing data collected from each sensor 4 are extracted Or it is calculated and transmitted to the master 2 as sensing data after filtering. In the present disclosure, the average value may include various average values such as an arithmetic average value, a moving average value, and a trimmed average value.

  The filtering may be processing for selecting a predetermined calculation result from sensing data from each of the sensors 4-1 to 4-n (hereinafter referred to as "calculation selection processing"). For example, when each sensing data from each sensor 4 includes an average value, a maximum value, a minimum value, etc. of a predetermined period, a part of these calculated values may be transmitted to the master 2 as sensing data after filtering. You may For example, when the maximum value among the calculation results consisting of the average value, the maximum value and the minimum value is selected, the maximum value in the sensor 4-1, the maximum value in the sensor 4-2,. The maximum value in n is transmitted to the master 2 as sensing data after filtering.

  In addition, the filtering secondarily recalculates an average value, a maximum value, a minimum value, a median value, and the like in a predetermined sampling period for each operation value of sensing data from each of the sensors 4-1 to 4-n. It may be processing (hereinafter, referred to as “secondary operation processing”). For example, an average value, a maximum value, a minimum value, a median value, and the like in one minute (that is, in 60 pieces of sensing data) are secondarily recalculated for sensing data input from the sensor 4-1 at one second intervals. The recalculation result is transmitted to the master 2 as sensing data after filtering.

  Alternatively, the filtering may be processing of removing sensing data sequentially input from each of the sensors 4-1 to 4-n at a predetermined ratio (hereinafter, referred to as “decimation processing”). For example, sensing data sequentially input from the sensor 4-1 is adopted or removed at a predetermined cycle. The above-mentioned filtering process is an example, and many other forms of filtering processes are possible. In addition, as filtering, two or more of the above-described sensor selection processing, tally processing, operation selection processing, secondary operation processing, or thinning processing may be appropriately combined.

  The setting change instruction is an instruction to change the setting of the above-mentioned filtering (sensor selection processing, tabulation processing, calculation selection processing, secondary calculation processing, thinning processing, and the like). The filter unit 35 changes the filtering setting in accordance with the setting change instruction received from the cloud server 5. The change of the setting may be switching between the above-mentioned filtering, or may be changing of the filtering level (degree of narrowing) in the same filtering process, or switching of enabling / disabling of filtering. It is also good. For example, if the setting change instruction relates to changing the application of sensing data, application or change of the above sensor selection process may be performed by the setting change instruction. In addition, if the setting change instruction relates to the communication amount or the communication cost, any application or change of the above process may be executed.

  The sensor 4 includes a detection unit 40, a CPU 41, a memory 42, and an input / output interface (I / F) 43. These units are connected in such a manner that they can exchange signals and data with one another via a bus. The CPU 41 includes an arithmetic processing unit 44 and a filter unit 45. It is assumed that the CPU 41 can execute not only the functions of the arithmetic processing unit 44 and the filter unit 45 but also general functions as a sensor CPU not particularly described, such as general control thereof. The memory 42 is a storage unit such as a RAM, a ROM, etc., which stores programs and data, and it is assumed that a program for executing the present embodiment has already been written. The CPU 41 and the memory 42 can be included in one microcomputer. The input / output I / F 43 is an interface for inputting an instruction from the slave 3 (input / output I / F 33) and outputting data to the slave 3 (input / output I / F 33).

  The detection unit 40 may include sensor elements for acquiring various detection data. Detection data is the temperature or humidity in the lighting fixture (temperature and humidity sensor), the inclination of the pole of the lighting fixture (tilting sensor), the vibration of the lighting fixture (acceleration sensor), the illuminance or luminance by illumination from the lighting fixture (illumination sensor) It may include ambient illumination (illuminance sensor), which is the brightness of sunlight around the lighting fixture, presence / absence of a human body (human sensor), and the like. As described above, various detection data include not only the operation or state of the lighting apparatus, the state around the lighting apparatus, but also information (for example, weather) which can be acquired by communication means (for example, communication by BLE) not shown. May also contain information on The detection unit 40 converts a physical quantity detected by each sensor element into an electrical signal, and generates detection data based on the electrical signal.

  The arithmetic processing unit 44 can calculate an average value, a maximum value, a minimum value, a median value, and the like within a predetermined period of the detection data acquired by the detection unit 40. The predetermined period is appropriately determined according to the sensor element of the detection unit 40. For example, the measurement target whose change is relatively slow such as temperature or humidity (light and humidity sensor) in the lighting fixture, inclination of the pole of the lighting fixture (tilting sensor), and ambient illumination such as sunshine around the lighting fixture (illumination sensor) The above predetermined period may be set relatively long. On the other hand, the above-mentioned predetermined period is set relatively short for the measurement object whose change is relatively fast, such as illuminance or luminance (illuminance sensor) by irradiation from the lighting equipment, presence / absence of human body (human sensor), etc. obtain.

  As described above, each sensor 4 includes the detection unit 40 that acquires detection data, and the arithmetic processing unit 44 that executes predetermined arithmetic processing on the detection data acquired within a predetermined time to generate sensing data. . Then, the maximum value, the minimum value, the average value, or the median value of the detection data acquired within the predetermined time is calculated as sensing data by the arithmetic processing. As a result, the sensing data output from each sensor 4 to the child device 3 is optimized in form or amount, the data processing load on the child device 3 is reduced, and standardization of the child device 3 is facilitated.

  The filter unit 45 filters the sensing data. By this filtering, the data amount of sensing data transmitted from the child device 3 to the parent device 2 (as a result, the data amount of sensing data transmitted from the parent device 2 to the cloud server 5) decreases. The filtering by the filter unit 45 may be performed after the calculation on the detection data by the calculation processing unit 44 or may be performed together with the calculation.

  The filtering may be, for example, calculation selection processing for selecting a predetermined calculation result from the sensing data calculated by the calculation processing unit 44. For example, when sensing data includes an average value, a maximum value, a minimum value, etc. of a predetermined period, a part (for example, only the maximum value) of these calculated values is output to handset 3 as sensing data after filtering You may do so.

  Further, the filtering may be thinning processing for removing sensing data calculated by the arithmetic processing unit 44 at a predetermined ratio. For example, sensing data calculated by the calculation processing unit 44 is adopted or removed at a predetermined cycle. Alternatively, the filtering may be processing of lengthening the sampling period of the detection data (hereinafter, referred to as “sampling increase processing”). The above-mentioned filtering process is an example, and many other forms of filtering processes are possible. Also, as filtering, two or more of the above-described operation selection processing, thinning processing, or sampling increase processing may be appropriately combined.

  The setting change instruction is an instruction to change the setting of the above-mentioned filtering (operation selection processing, thinning processing, sampling increase processing, and the like). The filter unit 45 changes the filtering setting in accordance with the setting change command received from the cloud server 5 via the handset 3. The change of the setting may be switching between the above filtering processes, or may be changing of the filtering level (degree of narrowing down) in the same filtering process, or switching of filtering enable / disable. May be For example, if the setting change command relates to a change in application of sensing data, switching of enabling / disabling of filtering of each sensor 4 may be performed. In addition, if the setting change instruction relates to the communication amount or the communication cost, any application or change of the above process may be executed.

  As described above, the setting of the filtering in the filter unit 35 or 45 is configured to be changed according to the application of sensing data or the communication amount or communication cost of the sensing data indicated by the setting change instruction. As a result, the communication state of sensing data can be adjusted in a flexible and optimal manner.

  In addition, although the structure to which both the filter part 35 of the subunit | mobile_unit 3 and the filter part 45 of the sensor 4 are applied is shown in this embodiment, any one of the filter part 35 and the filter part 45 may be employ | adopted.

  The cloud server 5 includes a transceiver 50, a storage unit 51, a data analysis unit 52, and a determination unit 53. The transceiver 50 may be a general communication device, capable of wireless communication with the base unit 2 (transmitter / receiver 23), and capable of wireless communication or wired communication with the terminal 6 (transmitter / receiver 60). .

  The storage unit 51 accumulates sensing data received from the base unit 2 via the transceiver 50. The storage unit 51 can also store a large amount of sensing data as big data. The data analysis unit 52 can perform statistical processing such as processing of the number of sensing data accumulated in the storage unit 51. Based on the analysis result of the data analysis unit 52, the determination unit 53 determines whether the sensing data is a normal value or an abnormal value, that is, whether the lighting fixture related to the analysis target sensing data is in a normal state To determine if it is in Then, the determination unit 53 causes the transceiver 50 to transmit the determination result to the terminal 6. The judgment result is the identification of the master unit 2 or slave unit 3 or sensor 4 to be determined, whether the lighting fixture corresponding to the slave unit 3 or sensor 4 is normal or abnormal, the level of abnormality if abnormal, etc. May be included. The cloud server 5 may include a plurality of sets of storage units 51, a data analysis unit 52, and a determination unit 53.

The transmission / reception unit 60 may be a general communication means capable of communicating with the cloud server 5 (transceiver 50). The CPU 61 and the memory 62 may be a processor and a memory that constitute a general computer. The input / output I / F 63 is a display screen including a keyboard, a mouse, a display screen and the like when the terminal 6 is a personal computer, and a touch screen when the terminal 6 is a tablet and a smartphone. On the display screen, the above determination result is displayed by a chart or the like.

Furthermore, the processing unit 71 may change the association setting of the base unit 2, the handset 3 and the sensor 4 stored in the storage unit 72 according to the input from the user I / F 73. In addition, the processing unit 71 may be configured to receive sensing data from the parent device 2 via the transmission / reception unit 70, and to display the sensing data on the user I / F 73 or save the sensing data in the storage unit 72. . However, while the cloud server 5 can receive sensing data from any of a large number of parent devices 2, the control device 7 receives sensing data only from the connected parent devices 2.

In the cloud server 5, the storage unit 51 stores sensing data, the data analysis unit 52 analyzes the accumulated sensing data, and the determination unit 53 analyzes the analysis result, that is, whether the lighting fixture corresponding to the sensing data is normal or abnormal And so on. When the abnormality is determined, the cloud server 5 notifies that effect to the registered e-mail address.

  On the other hand, in the setting change operation, the terminal 6 can transmit a setting change command to the cloud server 5. The cloud server 5 transmits a setting change command to the transmitting and receiving unit 23 of the parent device 2 by the transceiver 50. In the base unit 2, the communication control unit 24 transmits the received setting change command from the wireless communication unit 20 to the wireless communication unit 30 of the handset 3. Here, the setting change instruction may designate any one of handsets 3-1 to 3-m as a transmission destination, or designate all handsets 3-1 to 3-m as a transmission destination. It may be In any case, the communication control unit 24 causes the wireless communication unit 20 to transmit a setting change command to the slave 3 serving as the corresponding transmission destination. The setting change command is not only activated from the terminal 6, but is also automatically activated from the cloud server 5 according to a preset time, use of the lighting apparatus, other trigger conditions, etc. You may

  In the child device 3 that has received the setting change command, the filter unit 35 changes the setting of the above-described filtering for the sensing data received from each sensor 4 thereafter. That is, the content or the data amount of the sensing data transmitted from the slave unit 3 to the master unit 2 later is changed by the setting change.

  Further, in the slave unit 3 that has received the setting change command, the communication control unit 34 outputs the received setting change command to the sensor 4. Here, the setting change instruction may designate any of the sensors 4-1 to 4-n as an output destination, or may designate all of the sensors 4-1 to 4-n as an output destination. It may be In any case, the communication control unit 34 outputs a setting change command to the corresponding output destination sensor 4.

  In the sensor 4 to which the setting change command is input, the filter unit 45 changes the setting of the filtering for the sensing data to be calculated by the calculation processing unit 44 thereafter. That is, by this setting change, the content or data amount of the sensing data to be output from the sensor 4 to the child device 3 thereafter is changed.

  In the above-described operation, the configuration in which the setting of filtering can be changed in both the filter unit 35 of the slave unit 3 and the filter unit 45 of the sensor 4 has been described. However, the filter unit of the slave unit 3 and the filter unit of the sensor 4 The setting of filtering may be changed in any one of 45. In this case, the setting change instruction can include identification of which of the filtering in the filter unit 35 and the filtering in the filter unit 45 is to be changed. Naturally, the setting change instruction may not be output to the sensor 4 if the filtering change in the filter unit 45 is unnecessary.

  As described above, the illumination monitoring system 1 according to the present embodiment includes the parent device 2 capable of wireless communication with the cloud server 5, at least one child device 3 capable of wireless communication with the parent device 2, and the child devices 3. And at least one sensor 4 connected. The sensor 4 is configured to generate sensing data based on the detection data, the handset 3 is configured to wirelessly transmit the sensing data from the sensor 4 to the base unit 2, and the base unit 2 is received from the handset 3 It is configured to wirelessly transmit the sensed data to the cloud server 5 at a predetermined transmission timing. The handset 3 or the sensor 4 has a filter unit 35 or 45 for filtering sensing data, and the filter unit 35 or 45 is received from the cloud server 5 via the base unit 2 or the base unit 2 and the handset 3. It is configured to change the setting of the filtering according to the setting change instruction.

  Thus, the filter unit 35 or 45 of the slave 3 or the sensor 4 changes the setting of the filtering of the sensing data according to the setting change instruction from the cloud server 5, and the slave 3 is obtained by the filtering Wirelessly transmit sensing data to the master 2. As a result, the content or data amount of sensing data wirelessly transmitted from the slave unit 3 to the master unit 2 is optimized in a mode suitable for the restriction of wireless communication, loss of sensing data is suppressed, and finally the cloud server 5 Data reliability of the sensing data obtained in In addition, it is possible to adjust or reduce the communication amount of sensing data wirelessly transmitted from the slave unit 3 to the master unit 2. Therefore, in the illumination monitoring system 1 that manages sensing data on the cloud C using wireless communication, it is possible to improve data reliability and suppress communication costs.

Second Embodiment
In the first embodiment, the configuration has been shown in which the filtering is changed in the slave 3 or the sensor 4 to optimize the wireless communication between the master 2 and the slave 3. On the other hand, in the present embodiment, a configuration is shown in which the filtering is changed in the parent device 2 and the wireless communication between the parent device 2 and the cloud server 5 is optimized.

  The block diagram of the illumination monitoring system 1 of this embodiment is shown in FIG. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified. The present embodiment differs from the first embodiment in that the parent device 2 includes the filter unit 25.

  The CPU 21 of the parent device 2 includes a communication control unit 24 and a filter unit 25. The filter unit 25 filters the sensing data received from the slave 3 via the wireless communication unit 20 for a predetermined period. When a setting change command is received from the cloud server 5, the sensing data is filtered. By this filtering, the data amount of sensing data transmitted from the parent device 2 to the cloud server 5 decreases.

  The filtering is, for example, a process for selecting sensing data from a predetermined handset 3 among the sensing data collected from the plurality of handsets 3-1 to 3-m (hereinafter referred to as “child unit selection processing” ) May be. For example, sensing data from some handsets 3 with high priority among the handsets 3-1 to 3-m may be selected and transmitted to the cloud server 5 as sensing data after filtering. . In addition, in the first embodiment, such filtering of handset selection is enabled in the filter unit 35 of the handset 3 to be selected by the setting change instruction, and the filtering of the remaining handset 3 is performed. It can also be realized by disabling the filtering.

  Also, the filtering may be, for example, a sensor selection for selecting sensing data from a predetermined sensor 4 among sensing data collected from each sensor 4 connected to a plurality of handsets 3-1 to 3-m. It may be a process. For example, sensing data from some of the sensors 4 with high priority among the sensors 4 that detect physical quantities of different types or the same type may be selected and transmitted to the cloud server 5 as sensing data after filtering. . For example, in the filtering, when the priority of sensing data regarding presence / absence of a human body is high, sensing data from a human sensor connected to each of the child devices 3-1 to 3-m is prioritized (or Only sensing data from the human sensor will be transmitted to the cloud server 5).

  In addition, the filtering secondarily recalculates an average value, a maximum value, a minimum value, a median value, etc. in a predetermined sampling period for each operation value of sensing data from each of the child devices 3-1 to 3-m. It may be secondary arithmetic processing. For example, the average value, the maximum value, the minimum value, the median value, etc. in 10 minutes (that is, in 10 pieces of sensing data) are secondarily recalculated for sensing data input from slave unit 3-1 at 1 minute intervals. The recalculation result is transmitted to the cloud server 5 as sensing data after filtering.

  Alternatively, the filtering may be a thinning process that removes sensing data sequentially input from each of the slaves 3-1 to 3-m at a predetermined rate. For example, sensing data sequentially input from the child device 3-1 is adopted or removed at a predetermined cycle. The above-mentioned filtering process is an example, and many other forms of filtering processes are possible. Also, as filtering, two or more of the above-described slave unit selection processing, sensor selection processing, secondary calculation processing, or thinning-out processing may be appropriately combined.

  The setting change instruction is an instruction to change the setting of the above-mentioned filtering (for example, a child device selection process, a sensor selection process, a secondary operation process, or a thinning process). The filter unit 25 changes the filtering setting in accordance with the setting change instruction received from the cloud server 5. The change of the setting may be switching between the above filtering processes, or may be changing of the filtering level (degree of narrowing down) in the same filtering process, or switching of filtering enable / disable. May be For example, if the setting change instruction relates to changing the application of sensing data, the setting change instruction may execute application or change of the above-described slave unit selection processing or sensor selection processing. In addition, if the setting change instruction relates to the communication amount or the communication cost, any application or change of the above process may be executed. Thereby, when the transmission timing (transmission interval) from the parent device 2 to the cloud server 5 is set constant, the amount of data communication per one time is reduced or the data communication from the parent device 2 to the cloud server 5 If the amount is set to be constant, the transmission interval will be longer and as a result the communication cost will be reduced.

  Thus, the setting of the filtering in the filter unit 25 is configured to be changed in accordance with the application of sensing data or the communication amount or communication cost of the sensing data indicated by the setting change instruction. As a result, the communication state of sensing data can be adjusted in a flexible and optimal manner.

  The normal operation is similar to the operation shown in the first embodiment. On the other hand, in the setting change operation, the cloud server 5 transmits a setting change command received from the terminal 6 or activated by the cloud server 5 to the parent device 2. In the parent device 2, the filter unit 25 changes the above-described filtering for the sensing data received from each child device 3 thereafter. That is, the content or the data amount of the sensing data to be transmitted to the cloud server 5 thereafter is changed by this filtering.

  As described above, the illumination monitoring system 1 according to the present embodiment includes the parent device 2 capable of wireless communication with the cloud server 5, at least one child device 3 capable of wireless communication with the parent device 2, and the child devices 3. And at least one sensor 4 connected. The sensor 4 is configured to generate sensing data based on the detection data, the handset 3 is configured to wirelessly transmit the sensing data from the sensor 4 to the base unit 2, and the base unit 2 is received from the handset 3 It is configured to wirelessly transmit the sensed data to the cloud server 5. The parent device 2 has a filter unit 25 that filters the sensing data, and the filter unit 25 is configured to change the setting of the filtering in accordance with the setting change instruction received from the cloud server 5.

  As described above, the filter unit 25 of the parent device 2 changes the filtering setting of the sensing data according to the setting change instruction from the cloud server 5, and the sensing data is wirelessly transmitted to the cloud server 5 according to the changed filtering. As a result, the content or amount of sensing data transmitted from the master unit 2 to the cloud server 5 is optimized, the possibility of unnecessary data loss is reduced, and the data reliability of the sensing data obtained by the cloud server 5 is reduced. improves. In addition, it is possible to adjust or reduce the communication amount of sensing data transmitted from the parent device 2 to the cloud server 5. Therefore, in the illumination monitoring system 1 that manages sensing data on the cloud C using wireless communication, it is possible to improve data reliability and suppress communication costs.

In the second embodiment, the configuration in which the wireless communication from the master device 2 to the cloud server 5 is optimized by changing the setting of the filtering of the sensing data has been shown. On the other hand, in the present embodiment, a configuration is shown in which the transmission timing from the parent device 2 to the cloud server 5 is adjusted to optimize the wireless communication.

  FIG. 3 shows a block diagram of the illumination monitoring system 1 of the present embodiment. In the present embodiment, the same components as those in the first or second embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified. The present embodiment is different from the first and second embodiments in that the master unit 2 includes the transmission adjustment unit 26.

  The CPU 21 includes a communication control unit 24 and a transmission adjustment unit 26. The transmission adjustment unit 26 adjusts the setting of the transmission timing of the sensing data from the parent device 2 to the cloud server 5 in accordance with the setting change command received from the cloud server 5.

  The predetermined transmission timing may be defined by sensing data stored in the memory 22 reaching a set value, or may be defined by a fixed transmission interval. Then, the transmission adjustment unit 26 can adjust the setting of the predetermined transmission timing by adjusting the set value or the transmission interval. As a result, it is possible to flexibly adjust the amount of data communication in one transmission and the amount of data communication per unit time to realize an appropriate communication mode.

  In addition, the predetermined transmission timing (for example, transmission interval) is configured to be changed according to the communication data of the sensing data or the required level of the communication cost indicated by the setting change command. Thereby, the aspect of communication of sensing data can be adjusted flexibly.

  The normal operation is similar to the operation shown in the first and second embodiments. On the other hand, in the setting change process, the cloud server 5 transmits the setting change command received from the terminal 6 or the setting change command activated by the cloud server 5 to the parent device 2. The parent device 2 adjusts the transmission timing (for example, transmission interval) of sensing data to the cloud server 5 according to the setting change command. For example, in a situation where the terminal 6 does not require frequent data updates, such as a situation in which there is little access from the terminal 6 to the cloud server 5, the transmission interval is increased to reduce the number of transmissions, It is possible to reduce the communication cost while reducing the possibility of accompanying data loss. Therefore, it is possible to optimize (for example, maximize) the transmission interval according to the communication status. As described above, according to the configuration in which the transmission interval of the sensing data is changed by adjusting the setting of the transmission timing, the effect of the present embodiment can be obtained with a simple control configuration.
