By the way, in a lighting monitoring system in which sensing data obtained by a sensor is transferred to the cloud via a slave unit and a master unit, data reliability and communication cost related to transmission of sensing data from the sensor to the cloud become problems. Specific low-power wireless communication such as a sub giga band (for example, 920 MHz band) can be used between the master unit and the slave unit, and wireless communication such as 3G or 4G can be used between the master unit and the cloud. Wireless communication in the sub-giga band has advantages that it has a long reach, high diffraction, and is less susceptible to radio wave interference than other wireless communications such as the 2.4 GHz band. Therefore, in recent years, sensing technology using the above sub-giga band such as LoRa, SIGFOX, etc. has become widespread. On the other hand, the sub-giga band wireless communication has restrictions such as a wireless communication restriction (for example, 10%, that is, 6 minutes per hour) by the Radio Law. Further, there are restrictions that the communication speed is slower and the amount of data transfer is smaller than that of other wireless communications. Due to such restrictions on wireless communication between the master unit and the slave unit, there may be an interval in the transmission of the sensing data, and the sensing data may be missing. As a result, there is a problem that the reliability of the sensing data finally obtained in the cloud is lowered. Further, when a large number of sensors are connected to the slave unit, there is a problem that the amount of data communication from the slave unit to the master unit increases, the communication speed decreases, and the communication cost also increases. Furthermore, frequent transfer of sensing data from the master unit to the cloud may cause problems such as an increase in communication costs and an increase in the possibility of data loss.

According to the lighting monitoring system, the filter unit of the master unit changes the filtering setting of the sensing data in response to the setting change command from the cloud server, and the sensing data is wirelessly transmitted to the cloud server according to the changed filtering. This optimizes the content or amount of sensing data transmitted from the master unit to the cloud server, reduces the possibility of unnecessary data loss, and improves the data reliability of the sensing data obtained by the cloud server. In addition, it is possible to adjust or reduce the communication amount or communication cost of the sensing data transmitted from the master unit to the cloud server.

<First Embodiment>
FIG. 1 shows a block diagram of the lighting monitoring system 1 according to the present embodiment. The lighting monitoring system 1 includes a master unit 2, slave units 3-1 to 3 to m, sensors 4-1 to 4-n connected to each slave unit (slave unit 3-1 in FIG. 1), a cloud server 5, and a cloud server 5. A terminal 6 is provided. Further, if necessary, the control device 7 may be connected to the master unit 2. In the following description, the slave units 3-1 to 3 to m are collectively referred to as the slave unit 3 or any one of them is represented, and the sensors 4-1 to 4-n are collectively referred to or any one of them. Is referred to as a sensor 4 as a representative. Each handset 3 has the same configuration, but the number and types of sensors 4 connected to each handset 3 may be the same or different. Each slave unit 3 is arranged, for example, corresponding to a lighting fixture or a lighting fixture group (not shown). Each sensor 4 has substantially the same configuration except for the difference in the detection target, and is installed for the lighting fixture in which the corresponding slave unit 3 is arranged. The cloud server 5 exists on a cloud C such as the Internet. In the present embodiment, one master unit 2 is associated with the cloud server 5, but a plurality of master units 2 may be associated with the cloud server 5.

As a general rule, in normal operation, the sensor 4 generates sensing data based on detection data (for example, measurement data related to lighting equipment), the slave unit 3 transmits the sensing data to the master unit 2, and the master unit 2 transmits the sensing data. Is configured to be transmitted to the cloud server 5 at predetermined transmission intervals. Then, the terminal 6 can access the cloud server 5 and monitor the sensing data on the cloud C. The master unit 2 and each slave unit 3 may be wirelessly connected, and the slave unit 3 and the sensor 4 may be integrated on the same board, or may be configured on a separate board and connected by wire or wirelessly. .. In the present embodiment, the wireless connection between the master unit 2 and the slave unit 3 is a specific low power radio that uses 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 master unit 2 and the cloud server 5 are wirelessly connected by, for example, 3G or 4G (LTE), and the master unit 2 and the control device 7 are wiredly connected by a LAN or the like. The cloud server 5 and the terminal 6 are connected by wire or wirelessly via an arbitrary communication method.

The master unit 2 includes a wireless communication unit 20, a CPU 21, a memory 22, and a transmission / reception unit 23. Each of these parts is connected via a bus so that signals and data can be exchanged with each other. The wireless communication unit 20 is a wireless module that performs wireless communication with each slave unit 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 function of the communication control unit 24 but also a general function as a master CPU (such as generation of a lighting control signal to the slave unit 3), which is not specified in particular. The memory 22 is a storage unit such as a RAM or a ROM for storing a program 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 may be included in one microcomputer. The transmission / reception unit 23 is a communication means capable of wireless communication with the cloud server 5 (transmission / reception unit 50), and also has a wired communication function with the control device 7 (transmission / reception unit 70), if necessary.

The communication control unit 24 controls the transmission of the sensing data received from the slave unit 3 via the wireless communication unit 20 to the cloud server 5. The communication control unit 24 stores the sensing data in the memory 22, and causes the transmission / reception unit 23 to transmit the stored sensing data to the cloud server 5 at a predetermined transmission timing. In this way, the memory 22 functions as a buffer. That is, the communication control unit 24 is configured to collectively transfer the sensing data stored in this buffer to the cloud server 5 instead of sequentially transmitting the sensing data received from the slave unit 3 to the cloud server 5. .. As a result, the number of communications 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 master unit 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. It may be specified as a time point (that is, it may be set so that the amount of data communication at one time is constant). Further, the communication control unit 24 causes the wireless communication unit 20 to transmit the setting change command received from the cloud server 5 via the transmission / reception unit 23 to the slave unit 3. This setting change instruction will be described later.

The slave unit 3 includes a wireless communication unit 30, a CPU 31, a memory 32, and an input / output interface (I / F) 33. Each of these parts is connected via a bus so that signals and data can be exchanged with each other. The wireless communication unit 30 is a wireless module that performs wireless communication with the master unit 2 (wireless communication unit 20). The CPU 31 includes a communication control unit 34 and a filter unit 35. The CPU 31 can execute not only the functions of the communication control unit 34 and the filter unit 35, but also general functions as a slave CPU (such as lighting control of a lighting fixture (not shown)) such as integrated control of these. And. The memory 32 is a storage unit such as a RAM or a ROM for storing a program 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 may 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 commands to the sensor 4 (input / output I / F 43).

The communication control unit 34 causes the wireless communication unit 30 to transmit the sensing data input from the sensor 4 via the input / output I / F 33 from the wireless communication unit 30 to the master unit 2 in accordance with the communication restriction of the wireless communication between the slave unit 3 and the master 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 master unit 2 via the wireless communication unit 30 can be output from the input / output I / F 33 to the sensor 4. This 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. This filtering reduces the amount of sensing data transmitted from the slave unit 3 to the master unit 2 (and as a result, from the master unit 2 to the cloud server 5).

Even if the filtering is, for example, a process for selecting the sensing data from a predetermined sensor 4 among the 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 different or similar physical quantities, the sensing data from some of the high-priority sensors 4 among the sensors 4-1 to 4-n can be obtained. It may be selected and transmitted to the master unit 2 as sensing data after filtering. For example, in filtering, when the priority of sensing data related to temperature is high, the sensing data from the temperature sensor connected to each of the slave units 3-1 to 3-m has priority (or sensing from the temperature sensor). Only the data) is transmitted to the master unit 2.

Further, the filtering may be a process 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 “aggregation process”). For example, when the sensors 4-1 to 4-n are sensors that detect the same type of physical quantity, the average value, maximum value, minimum value, median value, etc. of n sensing data collected from each sensor 4 are extracted. Alternatively, it is calculated and transmitted to the master unit 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 mean value.

Further, the filtering may be a process for selecting a predetermined calculation result from the sensing data from each of the sensors 4-1 to 4-n (hereinafter, referred to as “calculation selection process”). For example, when each sensing data from each sensor 4 includes an average value, a maximum value, a minimum value, etc. in a predetermined period, a part of these calculated values is transmitted to the master unit 2 as sensing data after filtering. You may do it. 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 and the maximum value in the sensor 4-2, ..., Sensor 4-. The maximum value in n is transmitted to the master unit 2 as sensing data after filtering.

Further, in the filtering, the average value, the maximum value, the minimum value, the median value, etc. in the predetermined sampling period are secondarily recalculated for each calculated value of the sensing data from each of the sensors 4-1 to 4-n. It may be a process (hereinafter referred to as "secondary operation process"). For example, for the sensing data input from the sensor 4-1 at 1-second intervals, the average value, maximum value, minimum value, median value, etc. in 1 minute (that is, in 60 sensing data) are secondarily recalculated. , This recalculation result is transmitted to the master unit 2 as sensing data after filtering.

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

The setting change command is a command for changing the settings of the above-mentioned filtering (sensor selection processing, aggregation processing, calculation selection processing, secondary calculation processing, thinning processing, etc.). The filter unit 35 changes the filtering setting according to the setting change instruction received from the cloud server 5. The change of this setting may be a switch between the above filtering, a change of the filtering level (degree of narrowing down) in the same filtering process, or a switch of enabling / disabling filtering. May be good. For example, if the setting change command relates to a change in the use of the sensing data, the setting change command may execute the application or change of the sensor selection process. Further, if the setting change instruction relates to the communication amount or the communication cost, any of the above processes can be applied or changed.

The sensor 4 includes a detection unit 40, a CPU 41, a memory 42, and an input / output interface (I / F) 43. Each of these parts is connected via a bus so that signals and data can be exchanged with each other. 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, such as integrated control thereof, which are not specified in particular. The memory 42 is a storage unit such as a RAM or a ROM for storing a program 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 may be included in one microcomputer. The input / output I / F 43 is an interface for inputting an instruction from the slave unit 3 (input / output I / F 33) and outputting data to the slave unit 3 (input / output I / F 33).

The detection unit 40 may include a sensor element that acquires various detection data. The detection data includes the temperature or humidity inside the luminaire (temperature and humidity sensor), the tilt of the pole of the luminaire (tilt sensor), the vibration of the luminaire (acceleration sensor), and the illuminance or brightness due to irradiation from the luminaire (illuminance sensor). , Environmental illuminance (illuminance sensor), which is the brightness of the sunshine around the luminaire, presence / absence of the human body (human sensation sensor), and the like may be included. The various detection data includes not only the operation or state of the luminaire and the state around the luminaire as described above, but also information (for example, weather) that can be acquired by a communication means (for example, communication by BLE) (not shown). Information about) can also be included. The detection unit 40 converts the physical quantity detected by each sensor element into an electric signal, and generates detection data based on the electric signal.

The calculation processing unit 44 can calculate an average value, a maximum value, a minimum value, a median value, etc. of the detection data acquired by the detection unit 40 within a predetermined period. This predetermined period is appropriately determined according to the sensor element of the detection unit 40. For example, the temperature or humidity inside the luminaire (temperature / humidity sensor), the tilt of the pole of the luminaire (tilt sensor), the environmental illuminance such as the sunshine around the luminaire (illuminance sensor), etc. The above predetermined period can be set relatively long. On the other hand, for measurement targets that change relatively quickly, such as illuminance or brightness (illuminance sensor) due to irradiation from lighting equipment, presence / absence of human body (presence sensor), etc., the above predetermined period is set relatively short. obtain.

As described above, each sensor 4 has a detection unit 40 that acquires detection data, and an 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 the sensing data by the arithmetic processing. As a result, the sensing data output from each sensor 4 to the slave unit 3 is optimized in format or quantity, the data processing load of the slave unit 3 is reduced, and the standardization of the slave unit 3 becomes easy.

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

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

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

The setting change instruction is an instruction for changing the settings of the above-mentioned filtering (calculation selection processing, thinning processing, sampling increase processing, etc.). The filter unit 45 changes the filtering setting according to the setting change instruction received from the cloud server 5 via the slave unit 3. The change of this setting may be a switch between the above filtering processes, a change of the filtering level (degree of narrowing down) in the same filtering process, or a switch of enabling / disabling filtering. You may. For example, if the setting change command is related to a change in the use of the sensing data, switching between enabling / disabling filtering of each sensor 4 can be executed. Further, if the setting change instruction relates to the communication amount or the communication cost, any of the above processes can be applied or changed.

In this way, the filtering setting in the filter unit 35 or 45 is configured to be changed according to the use of the sensing data indicated by the setting change command, the communication amount of the sensing data, or the communication cost. As a result, the communication state of the sensing data can be adjusted flexibly and in an optimum manner.

Although the present embodiment shows a configuration in which both the filter unit 35 of the slave unit 3 and the filter unit 45 of the sensor 4 are applied, either the filter unit 35 or the filter unit 45 may be adopted.

The transmitter / receiver 50 may be a general communication device, and may be capable of wireless communication with the master unit 2 (transmission / reception unit 23) and wireless communication or wired communication with the terminal 6 (transmission / reception unit 60). ..

The storage unit 51 stores the sensing data received from the master unit 2 via the transmitter / receiver 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 the number of sensing data stored 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 equipment related to the sensing data to be analyzed is in a normal state or not. It is determined whether the state is in the same state. Then, the determination unit 53 causes the transmitter / receiver 50 to transmit the determination result to the terminal 6. The judgment result is the identification of the master unit 2, the slave unit 3 or the sensor 4 to be judged, whether the state of the lighting equipment corresponding to the slave unit 3 or the sensor 4 is normal / abnormal, and if it is abnormal, the level of abnormality, etc. May include.

The data stored in the storage unit 72 includes a setting for associating the master unit 2, the slave unit 3, and the sensor 4, and this setting can also be stored in the memory 22 of the master unit 2. The user I / F 73 is a graphical user interface (GUI) or the like that enables input / output of information on the touch panel. Although not described in detail in the present disclosure, the control device 7 outputs a lighting control command to the master unit 2, and the slave unit 3 passes through a processing unit (not shown) for lighting control of the master unit 2 and the slave unit 3. It may be configured to perform lighting control (lighting, dimming, extinguishing, etc.) of a luminaire (not shown) that may be connected to. Further, the processing unit 71 may be able to change the setting of the association between the master unit 2, the slave unit 3 and the sensor 4 stored in the storage unit 72 in response to the input from the user I / F 73. Further, the processing unit 71 may be configured to receive sensing data from the master unit 2 via the transmission / reception unit 70, display the sensing data in the user I / F 73, or store the sensing data in the storage unit 72. .. However, while the cloud server 5 can receive sensing data from any number of master units 2, the control device 7 receives sensing data only from the connected master unit 2.

Here, the operation of the lighting monitoring system 1 will be described based on the above configuration.
In the normal operation, in the sensor 4, the detection unit 40 acquires the detection data, the arithmetic processing unit 44 performs a predetermined operation on the detection data to generate the sensing data, and the CPU 41 outputs the sensing data to the slave unit 3. In the slave unit 3, the communication control unit 34 causes the wireless communication unit 30 to transmit the sensing data collected from the sensors 4-1 to 4-n to the wireless communication unit 20 of the master unit 2. In the master unit 2, the communication control unit 24 stores the sensing data collected from the slave units 3-1 to 3 to m in the memory 22, and the stored sensing data is stored from the transmission / reception unit 23 to the cloud server 5 at a predetermined timing.

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

On the other hand, in the setting change operation, the terminal 6 can transmit the setting change command to the cloud server 5. The cloud server 5 transmits a setting change command to the transmission / reception unit 23 of the master unit 2 by the transmission / reception unit 50. In the master unit 2, the communication control unit 24 causes the wireless communication unit 20 to transmit the received setting change command to the wireless communication unit 30 of the slave unit 3. Here, the setting change command may specify any one of the slave units 3-1 to 3-m as the transmission destination, or specify all of the slave units 3-1 to 3-m as the transmission destination. It may be the one that has been used. In any case, the communication control unit 24 causes the wireless communication unit 20 to transmit a setting change command to the slave unit 3 which is the corresponding transmission destination. The setting change command is not only activated from the terminal 6, but is automatically activated from the cloud server 5 according to a preset time, a usage schedule of the lighting equipment, other trigger conditions, and the like. You may do it.

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

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 command may be one in which any one of the sensors 4-1 to 4-n is designated as an output destination, or one in which all of the sensors 4-1 to 4-n are designated as output destinations. 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 filtering setting for the sensing data to be subsequently calculated by the arithmetic processing unit 44. That is, by changing this setting, the content or the amount of sensing data that is subsequently output from the sensor 4 to the slave unit 3 is changed.

In the above operation, the configuration in which the filtering setting can be changed in both the filter unit 35 of the slave unit 3 and the filter unit 45 of the sensor 4 is shown, but the filter unit 35 of the slave unit 3 and the filter unit of the sensor 4 are shown. The filtering setting may be changed to any one of the 45. In this case, the setting change instruction can include identification of whether to change the filtering in the filter unit 35 or the filtering in the filter unit 45. As a matter of course, when it is not necessary to change the filtering in the filter unit 45, the setting change command may not be output to the sensor 4.

As described above, the lighting monitoring system 1 of the present embodiment is provided for each of the master unit 2 capable of wireless communication with the cloud server 5, at least one slave unit 3 capable of wireless communication with the master unit 2, and the slave unit 3. It comprises at least one connected sensor 4. The sensor 4 is configured to generate sensing data based on the detection data, the slave unit 3 is configured to wirelessly transmit the sensing data from the sensor 4 to the master unit 2, and the master unit 2 receives from the slave unit 3. It is configured to wirelessly transmit the sensed data to the cloud server 5 at a predetermined transmission timing. Then, the slave unit 3 or the sensor 4 has a filter unit 35 or 45 for filtering the sensing data, and the filter unit 35 or 45 is received from the cloud server 5 via the master unit 2 or the master unit 2 and the slave unit 3. It is configured to change the filtering settings according to the setting change command.

In this way, the filter unit 35 or 45 of the slave unit 3 or the sensor 4 changes the filtering setting of the sensing data in response to the setting change command from the cloud server 5, and the slave unit 3 is obtained by the filtering. The sensing data is wirelessly transmitted to the master unit 2. As a result, the content or amount of sensing data wirelessly transmitted from the slave unit 3 to the master unit 2 is optimized in a manner suitable for the restrictions of wireless communication, the loss of sensing data is suppressed, and the cloud server 5 finally performs. The data reliability of the sensing data obtained in the cloud is improved. Further, it is possible to adjust or reduce the communication amount of the sensing data wirelessly transmitted from the slave unit 3 to the master unit 2. Therefore, in the lighting monitoring system 1 that manages the sensing data on the cloud C by using wireless communication, it is possible to improve the data reliability and suppress the communication cost.

<Second embodiment>
In the first embodiment, the filtering is changed in the slave unit 3 or the sensor 4, and the wireless communication between the master unit 2 and the slave unit 3 is optimized. On the other hand, the present embodiment shows a configuration in which filtering is changed in the master unit 2 to optimize wireless communication between the master unit 2 and the cloud server 5.

FIG. 2 shows a block diagram of the lighting monitoring system 1 of the present embodiment. In the present embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified. This embodiment is different from the first embodiment in that the master unit 2 includes the filter unit 25.

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

Filtering is, for example, a process for selecting sensing data from a predetermined slave unit 3 among sensing data collected from a plurality of slave units 3-1 to 3-m (hereinafter referred to as "slave unit selection process"). ) May be. For example, the sensing data from some of the slave units 3 to 3 to 3 to high priority may be selected and transmitted to the cloud server 5 as the filtered sensing data. .. Further, in the first embodiment, such filtering of the handset selection enables filtering in the filter unit 35 of the handset 3 to be selected by the setting change command, and the filter unit 35 of the remaining handset 3 is used. It can also be achieved by disabling filtering.

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

Further, in the filtering, the average value, the maximum value, the minimum value, the median value, etc. in the predetermined sampling period are secondarily recalculated for each calculated value of the sensing data from each of the slave units 3-1 to 3 to m. It may be a quadratic arithmetic processing to be performed. For example, for the sensing data input from the slave unit 3-1 at 1-minute intervals, the average value, maximum value, minimum value, median value, etc. in 10 minutes (that is, in 10 sensing data) are secondarily recalculated. Then, this recalculation result is transmitted to the cloud server 5 as sensing data after filtering.

Alternatively, the filtering may be a thinning process for removing sensing data sequentially input from each of the slave units 3-1 to 3 to m at a predetermined ratio. For example, the sensing data sequentially input from the slave unit 3-1 is adopted or removed at a predetermined cycle. The above filtering process is an example, and many other modes of filtering processing are possible. Further, as the filtering, two or more of the above-mentioned slave unit selection process, sensor selection process, secondary calculation process, or thinning process may be appropriately combined.

The setting change command is a command for changing the settings of the above-mentioned filtering (slave unit selection process, sensor selection process, secondary calculation process, thinning process, etc.). The filter unit 25 changes the filtering setting according to the setting change instruction received from the cloud server 5. The change of this setting may be a switch between the above filtering processes, a change of the filtering level (degree of narrowing down) in the same filtering process, or a switch of enabling / disabling filtering. You may. For example, if the setting change command relates to a change in the use of the sensing data, the setting change command may execute the application or change of the slave unit selection process or the sensor selection process. Further, if the setting change instruction relates to the communication amount or the communication cost, any of the above processes can be applied or changed. As a result, when the transmission timing (transmission interval) from the master unit 2 to the cloud server 5 is set to be constant, the amount of data communication per time is reduced, or the data communication from the master unit 2 to the cloud server 5 is performed. When the amount is set to a constant value, the transmission interval becomes long, and as a result, the communication cost decreases.

In this way, the filtering setting in the filter unit 25 is configured to be changed according to the use of the sensing data indicated by the setting change command, the communication amount of the sensing data, or the communication cost. As a result, the communication state of the sensing data can be adjusted flexibly and in an optimum manner.

The normal operation is the same as 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 master unit 2. In the master unit 2, the filter unit 25 changes the above-mentioned filtering for the sensing data received from each slave unit 3 thereafter. That is, by this filtering, the content or the amount of sensing data to be subsequently transmitted to the cloud server 5 is changed.

As described above, the lighting monitoring system 1 of the present embodiment is provided for each of the master unit 2 capable of wireless communication with the cloud server 5, at least one slave unit 3 capable of wireless communication with the master unit 2, and the slave unit 3. It comprises at least one connected sensor 4. The sensor 4 is configured to generate sensing data based on the detection data, the slave unit 3 is configured to wirelessly transmit the sensing data from the sensor 4 to the master unit 2, and the master unit 2 receives from the slave unit 3. It is configured to wirelessly transmit the sensed data to the cloud server 5. The master unit 2 has a filter unit 25 for filtering sensing data, and the filter unit 25 is configured to change the filtering setting in response to a setting change instruction received from the cloud server 5.

In this way, the filter unit 25 of the master unit 2 changes the filtering setting of the sensing data in response to the setting change command 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 improved. improves. Further, it is possible to adjust or reduce the communication amount of the sensing data transmitted from the master unit 2 to the cloud server 5. Therefore, in the lighting monitoring system 1 that manages the sensing data on the cloud C by using wireless communication, it is possible to improve the data reliability and suppress the communication cost.

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

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

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

The predetermined transmission timing may be defined by the sensing data stored in the memory 22 reaching a set value, or may be defined by a fixed transmission interval. Then, the transmission adjusting unit 26 can adjust the predetermined transmission timing setting by adjusting the above set value or the transmission interval. This makes it 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.

Further, the predetermined transmission timing (for example, transmission interval) is configured to be changed according to the required level of the communication amount or communication cost of the sensing data indicated by the setting change command. This makes it possible to flexibly adjust the mode of communication of the sensing data.

The normal operation is the same as 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 master unit 2. The master unit 2 adjusts the transmission timing (for example, transmission interval) of the sensing data to the cloud server 5 in response to this setting change command. For example, in a situation where the terminal 6 does not require high-frequency data update, such as a situation where the access from the terminal 6 to the cloud server 5 is low, the transmission interval is increased to reduce the number of transmissions, and the transmission is performed. It is possible to reduce the possibility of data loss and the communication cost. Therefore, it is possible to optimize (for example, maximize) the transmission interval according to the communication status. As described above, the effect of the present embodiment can be obtained with a simple control configuration by the configuration in which the transmission interval of the sensing data is changed by adjusting the transmission timing setting.

As described above, the lighting monitoring system 1 of the present embodiment is provided for each of the master unit 2 capable of wireless communication with the cloud server 5, at least one slave unit 3 capable of wireless communication with the master unit 2, and the slave unit 3. It comprises at least one connected sensor 4. The sensor 4 is configured to generate sensing data based on the detection data, and the slave unit 3 is configured to wirelessly transmit the sensing data from the sensor 4 to the master unit 2. Then, the master unit 2 has a memory 22 that stores the sensing data received from the slave unit 3, a communication control unit 24 that wirelessly transmits the sensing data stored in the memory 22 to the cloud server 5 at a predetermined transmission timing, and a cloud. The transmission adjustment unit 26 that adjusts the transmission timing setting according to the setting change command received from the server 5 is included.

In this way, the communication control unit 24 of the master unit 2 wirelessly transmits the sensing data stored in the memory 22 to the cloud server 5 at a predetermined transmission timing, and the transmission adjustment unit 26 is set to be received from the cloud server 5. Adjust the transmission timing setting according to the change command. As a result, the number of times of communication of the sensing data transmitted from the master unit 2 to the cloud server 5 can be reduced according to the communication status. Therefore, in the lighting monitoring system 1 that manages the sensing data on the cloud C by using wireless communication, it is possible to improve the data reliability and suppress the communication cost.
