DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0015] The terms "first," "second," "third," etc. in this disclosure are used merely for identification purposes and are not intended to impose any ordering on their objects.

[0016] First Embodiment 1 to 8 show a management system according to a first embodiment of the present invention. As shown in Fig. 1, the management system A1 of this embodiment includes a plurality of lighting devices L, a control device Ct, a plurality of first sensor devices Ea, a plurality of second sensor devices Eb, and a setting device CL. The management system A1 is a system that manages the measurement of indoor and outdoor temperatures of a building such as a warehouse.

[0017] [Lighting device L (relay unit)] The lighting device L is a specific example of the relay unit in the present invention. A specific example of the relay unit is not limited to the lighting device L. For example, a relay unit having a dedicated configuration in which the light source unit 11 is removed from the lighting device L described below may be used.

[0018] The lighting devices L are used for indoor lighting, and are installed at various locations such as ceilings, walls, and floors. The lighting devices L may also be used for outdoor lighting. The specific form of the lighting device L is not limited, and various forms such as alternative lighting for straight tube fluorescent lamps, high ceiling lighting, ceiling lights, downlights, base lights, and spotlights can be appropriately adopted. In the following description, the lighting device L is referred to as the lighting device L when describing a general configuration of the lighting device L, and the lighting devices L may be distinguished from each other by symbols such as lighting device L1, . . . , lighting device Ln (n is a natural number). The lighting devices L1 to Ln may have the same configuration, may have a part in common with each other, or may have different configurations. In the following description, unless otherwise specified, a case in which the lighting devices L1 to Ln have the same configuration will be described as an example.

[0019] 2 is a block diagram of the lighting device L. The lighting device L includes a light source unit 11, a control unit 12, a storage unit 13, a wireless communication module 14, and a power supply unit 15.

[0020] The light source unit 11 is a part that performs a light emitting function in the lighting device L1. The specific configuration of the light source unit 11 is not limited in any way, and may be, for example, a substrate and a plurality of LEDs mounted in a row on the substrate. In addition, the lighting device L1 may have a transparent or semi-transparent cover (not shown) that transmits light from the light source unit 11.

[0021] The control unit 12 is for controlling each part of the lighting device L based on, for example, instructions from the control device Ct. The specific configuration of the control unit 12 is not particularly limited, and may be, for example, a CPU. The storage unit 13 is for storing information necessary for the control of the control unit 12, and may be, for example, a semiconductor memory. Note that the storage unit 13 is not limited to being built into the housing (not shown) of the lighting device L, and may be detachably provided outside the housing of the lighting device L.

[0022] The wireless communication module 14 is a module for performing wireless communication with the control device Ct, the lighting devices L, the first sensor devices Ea, and the second sensor devices Eb, and transmits and receives wireless signals. The wireless communication module 14 is connected to the control unit 12 by, for example, UART (Universal Asynchronous Receiver Transmitter) communication, but is not limited to this. The wireless communication module 14 has a first wireless communication unit 141 and a second wireless communication unit 142.

[0023] The functions of the wireless communication module 14 include receiving signals from the control device Ct, the other lighting devices L, the first sensor device Ea, and the second sensor device Eb, and transmitting data included in the received signals to the control unit 12. The wireless communication module 14 also transmits an acknowledgement signal indicating that a lighting control signal has been received to the control device Ct. The wireless communication module 14 may also transmit a status information signal indicating the operating status of the lighting device L to the control device Ct.

[0024] In this embodiment, a unique luminaire ID of each of the multiple lighting devices L is stored in the wireless communication module 14. The information format of the luminaire ID is not particularly limited, and for example, a MAC (Media Access Control) address is used. The luminaire ID may be stored in either the first wireless communication unit 141 or the second wireless communication unit 142, or in a component of the wireless communication module 14 other than these, or may be stored in, for example, the storage unit 13.

[0025] The first wireless communication unit 141 is for performing wireless communication using the first protocol with the control device Ct and other lighting devices L. The communication frequency of the wireless communication using the first protocol is not limited in any way, and examples thereof include 920 MHz band, 2.4 GHz band, and 5 GHz band. In addition, specific examples of the first protocol are not particularly limited, and examples thereof include Bluetooth (registered trademark) including BLE (Bluetooth Low Energy), Zigbee (registered trademark), and Wi-Fi (registered trademark). In this embodiment, a wireless communication network Cn1, which is a mesh network, is constructed by a plurality of lighting devices L having the first wireless communication unit 141 and the control device Ct. Since the first protocol is used to transfer various data between a plurality of lighting devices L as described later, a protocol capable of constructing a mesh network while ensuring the transfer speed and reliability required for the data transfer is selected.

[0026] The second wireless communication unit 142 is for performing wireless communication with the first sensor device Ea and the second sensor device Eb using a second protocol. The communication frequency of the wireless communication using the second protocol is not limited in any way, and examples thereof include the 920 MHz band, the 2.4 GHz band, and the 5 GHz band. In addition, specific examples of the second protocol are not particularly limited, and examples thereof include Bluetooth (registered trademark) including BLE (Bluetooth Low Energy), Zigbee (registered trademark), and Wi-Fi (registered trademark). In the illustrated example, the second wireless communication unit 142 is connected to the first wireless communication unit 141 by SPI (Serial Peripheral Interface) communication, but is not limited thereto.

[0027] It is preferable to select the first protocol and the second protocol to have different communication frequencies so that the communications do not interfere with each other. It is also preferable to make the communication timings of the wireless communication by the first wireless communication unit 141 and the wireless communication by the second wireless communication unit 142 different from each other. Note that the wireless communication using the second protocol may be selected to have a shorter communication distance than the wireless communication using the first protocol, for example.

[0028] For example, when the wireless communication module 14 receives a request signal from the control device Ct requesting data acquisition of the first sensor device Ea and the second sensor device Eb by the first wireless communication unit 141, the wireless communication module 14 constructs transfer data by converting the request signal from the first protocol to the second protocol, and transmits the transfer data from the control unit 12 to the first sensor device Ea and the second sensor device Eb. Also, when the second wireless communication unit 142 receives measurement data transmitted from the first sensor device Ea and the second sensor device Eb, the wireless communication module 14 constructs transfer data by converting the measurement data to the first protocol, and transmits the transfer data to the control device Ct. As a specific example, the wireless communication module 14 detects from a protocol flag in the communication data that the measurement data from the first sensor device Ea and the second sensor device Eb is communication using the second protocol. Next, the wireless communication module 14 performs a predetermined process according to a procedure corresponding to the second protocol and receives the measurement data by the second wireless communication unit 142. Then, the wireless communication module 14 constructs transfer data by converting the measurement data into a data format for communication using the first protocol, and transmits the data to the adjacent lighting device L in the wireless communication network Cn1. Note that the construction of the transfer data includes a process of generating new transfer data. Moreover, the construction of the transfer data includes a process of selecting transfer data that matches a condition from a plurality of transfer data prepared in advance. In the following description, unless otherwise specified, the construction of the transfer data is used to include these processes.

[0029] The power supply unit 15 is for supplying power required for operation to the light source unit 11, the control unit 12, the wireless communication module 14, etc. The power supply unit 15 has a function as an AC / DC converter that converts commercial AC power of 100V or 200V into DC power, a voltage transformation function, etc.

[0030] [Control device Ct] The control device Ct controls the lighting of the lighting devices L1-Ln and the measurement of the first sensor devices Ea and the second sensor devices. In this embodiment, the control device Ct may be installed in the same building (such as a warehouse) as the lighting devices L1-Ln, or in a different building. When the control device Ct and the lighting devices L1-Ln are located at a certain distance from each other, the control device Ct and the lighting devices L1-Ln may communicate with each other using not only wireless communication but also wired communication and wireless communication. The management system A1 may include at least one control device Ct, and may include multiple control devices Ct in other configurations. The control device Ct in this embodiment is capable of communicating with both the lighting devices L.

[0031] 3 is a block diagram of the control device Ct. In this embodiment, the control device Ct includes a display unit 21, a control unit 22, a storage unit 23, a wireless communication unit 24, and a power supply unit 25.

[0032] The display unit 21 is not necessarily required in the lighting control method of the management system A1 described below, but is used for initial setting and maintenance of the control device Ct. The display unit 21 is, for example, a liquid crystal display, and may further have a touch panel function. Also, instead of the display unit 21 functioning as a touch panel, the control device Ct may be provided with a separate operation device such as a keyboard or a mouse.

[0033] The control unit 22 is a main component that controls the lighting of the lighting devices L1-Ln and the measurement of the first sensor devices Ea and the second sensor devices, and serves to control each part of the control device Ct. For example, the control unit 22 transmits a control signal to the wireless communication unit 24 so that the wireless communication unit 24 transmits a control signal to the target lighting device L based on an instruction signal received from the setting device CL. The specific configuration of the control unit 22 is not particularly limited, and may be, for example, a CPU. The storage unit 23 stores information such as programs and setting conditions required for the control of the control unit 22, and may be, for example, a semiconductor memory or a hard disk drive.

[0034] The wireless communication unit 24 is for performing wireless communication with the first wireless communication unit 141 of the wireless communication module 14 of the multiple lighting devices L1 to Ln. The frequency band of the wireless communication unit 24 and the wireless communication standard that it complies with are wireless communication using the above-mentioned first protocol. The wireless communication unit 24 transmits, for example, a control signal from the control unit 22 to the multiple lighting devices L1 to Ln. It also transmits a measurement request signal to the multiple first sensor devices Ea and the multiple second sensor devices. Alternatively, it receives an instruction signal transmitted from the setting device CL. The received instruction signal is transmitted to the control unit 22. In addition to the wireless communication unit 24, the control device Ct has a wired or wireless communication circuit that connects to the Internet.

[0035] The power supply unit 25 is for supplying power necessary for operation to the display unit 21, the control unit 22, the wireless communication unit 24, etc. The power supply unit 25 has a function as an AC / DC converter that converts commercial AC power of 100V or 200V into DC power, a voltage transformation function, etc.

[0036] The control device Ct has luminaire IDs of the multiple lighting devices L and device IDs of the multiple first sensor devices Ea and the multiple second sensor devices, which are stored, for example, in the storage unit 43. The luminaire IDs and device IDs held by the control device Ct may be MAC addresses serving as luminaire IDs held by the lighting device L and MAC addresses serving as device IDs held by the first sensor device Ea and the second sensor device, or may be other luminaire IDs and device IDs associated with these MAC addresses.

[0037] A clock unit (not shown) may be separately arranged in the management system A1. This clock unit receives FM radio waves and transmits time information to the control device Ct via the wireless communication network Cn1. This time information is added to data transmitted from the control device Ct to each lighting device L, the first sensor device Ea, and the second sensor device. Each lighting device L, each first sensor device Ea, and each second sensor device counts their own time based on the received clock information. This makes it possible to more accurately set the time of the devices and equipment constituting the management system A1.

[0038] [Setting device CL] The setting device CL constructs a setting command for setting the transmission period of the first sensor device Ea and the second sensor device Eb by a process described later. The setting device CL is constructed, for example, by a commercial cloud service or the like, and has a control unit 61, a storage unit 62, and a communication unit 63. The control unit 61 controls the operation of the setting device CL described later, and for example, a CPU or the like is used. The storage unit 62 stores the specification information described later in the management system A1 and the setting command prepared in advance, and for example, a semiconductor memory, a hard disk, or the like is used. The communication unit 63 communicates with the control device Ct and the mobile terminal Md via a public network (Internet), and is capable of either or both of wired communication and wireless communication. Note that the setting device of the present invention is not limited to an example constructed on a cloud, and may be, for example, a server device installed in a place different from the control device Ct or a server device installed in the same store as the control device Ct. Note that the construction of the setting command includes a process in which the control unit 61 executes a program to generate a new setting command. Furthermore, constructing a setting command includes a process in which a plurality of pre-prepared setting commands are stored in storage unit 62, and control unit 61 selects a setting command that matches a condition from among these setting commands. In the following explanation, unless otherwise specified, constructing a setting command will be used to include these processes.

[0039] [First sensor device Ea, second sensor device Eb] The first sensor device Ea and the second sensor device Eb are devices that measure temperature and humidity, which are physical quantities related to the environment in which they are installed, and transmit the measurement results by wireless communication. FIG. 4(a) is a block diagram of the first sensor device Ea, and FIG. 4(b) is a block diagram of the second sensor device Eb. The specific configurations of the first sensor device Ea and the second sensor device Eb may be different or the same. In the following description, a case in which the first sensor device Ea and the second sensor device Eb have a common configuration will be described as an example.

[0040] The first sensor device Ea measures outdoor temperature and humidity, and is installed, for example, outside a building (warehouse), for example, near the entrance of the warehouse where outdoor temperature and humidity can be easily measured. The second sensor device Eb measures indoor temperature, and is installed, for example, inside a building (warehouse). Each of the first sensor device Ea and the second sensor device Eb in this embodiment includes a sensor unit 41, a control unit 42, a storage unit 43, a wireless communication unit 44, and a power supply unit 45. Note that the specific configurations of the first sensor device Ea and the second sensor device Eb are not limited in any way, and in addition to a configuration in which they are installed as dedicated devices, they may also be in the form of a control switch for air conditioning equipment, lighting equipment, etc.

[0041] In the following description, when describing the general configuration of the first sensor device Ea and the second sensor device Eb, they will be referred to as the first sensor device Ea and the second sensor device Eb, and when distinguishing between the multiple first sensor devices Ea and the multiple second sensor devices Eb, symbols such as the first sensor device Ea1, the first sensor device Eap, the second sensor device Eb1, and the second sensor device Ebq may be used as appropriate (p and q are both natural numbers). The multiple first sensor devices Ea1 to Eap and the second sensor devices Eb1 to Eaq may have the same configuration, may have a part in common with each other, or may have different configurations from each other. In the following description, unless otherwise specified, a case will be described in which the multiple first sensor devices Ea1 to Eap and the second sensor devices Eb1 to Eaq have the same configuration.

[0042] The sensor unit 41 serves to measure physical quantities related to the environments of the first sensor device Ea and the second sensor device Eb. The sensor unit 41 of the first sensor device Ea is a temperature sensor and a humidity sensor. The sensor unit 41 of the second sensor device Eb is a temperature sensor. The measurement principle of the sensor unit 41 is not limited in any way.

[0043] The control unit 42 is for controlling each part of the first sensor device Ea and the second sensor device Eb. The specific configuration of the control unit 42 is not particularly limited, and may be, for example, a CPU. The storage unit 43 is for storing information such as programs and setting conditions required for the control of the control unit 42, and may be, for example, a semiconductor memory.

[0044] The wireless communication unit 44 is for performing wireless communication using the above-mentioned second protocol with the corresponding lighting device L. For example, the first sensor device Ea1 and the lighting device L1 perform wireless communication using the second protocol, and the second sensor device Ebq and the lighting device Ln perform wireless communication using the second protocol.

[0045] In this embodiment, the first sensor device Ea and the second sensor device Eb have unique device IDs. There is no particular limitation on the device ID, and for example, a MAC (Media Access Control) address is used. The device IDs may be stored in the wireless communication unit 44 or, for example, in the storage unit 43.

[0046] The power supply unit 45 is for supplying power necessary for operation to the sensor unit 41, the control unit 42, the wireless communication unit 44, etc. The power supply unit 45 is, for example, an AC / DC converter that converts commercial AC power of 100V or 200V into DC power, a voltage transformation function, or a rechargeable battery.

[0047] When a setting command, which will be described later, received from the corresponding lighting device L includes the device ID of the device itself, the wireless communication unit 44 transmits the setting command to the control unit 42. The control unit 42 sets a transmission cycle according to the setting command. The control unit 42 also transmits a measurement request to the sensor unit 41. The sensor unit 41 outputs a measurement value obtained as a result of the measurement to the control unit 42. The control unit 42 constructs measurement data including the device ID, the measurement value, the measurement time (timestamp), and the like, and transmits the measurement data from the wireless communication unit 44 according to the transmission cycle. Note that the construction of the measurement data includes a process in which the control unit 42 executes a program to generate new measurement data. Also, the construction of the measurement data includes a process in which, for example, a plurality of measurement data prepared in advance is stored in the storage unit 43, and the control unit 42 selects measurement data that matches a condition from the measurement data. In the following description, unless otherwise specified, the construction of the measurement data is used to include these processes.

[0048] Here, the transmission period is a period in which the first sensor device Ea and the second sensor device Eb transmit measurement data. The measurement period in which the sensor unit 41 of the first sensor device Ea and the second sensor device Eb performs measurement may be the same as the transmission period, or may be different. For example, the first sensor device Ea and the second sensor device Eb may set the transmission period included in the setting command as the measurement period of the own device. In this case, the transmission period and the measurement period are the same. On the other hand, for example, the measurement period may be set at the initial setting of the first sensor device Ea and the second sensor device Eb, and the sensor unit 41 may perform measurement at this initially set measurement period. Also, the setting command may include a measurement period different from the transmission period. In this case, the first sensor device Ea and the second sensor device Eb set the measurement period of the own device to the measurement period included in the setting command. Alternatively, a measurement request signal may be transmitted from the setting device CL or the control device Ct, etc. The first sensor device Ea and the second sensor device Eb perform measurement by the sensor unit 41 every time they receive a measurement request signal. In addition, when the measurement period and the transmission period are different, the measurement period is usually set to a period shorter than the transmission period that can be set, and measurement data including multiple measurement results (or multiple pieces of measurement data) are transmitted in one transmission process.

[0049] [Mobile terminal Md] The mobile terminal Md is a terminal operated by a user of the management system A1. The mobile terminal Md is not particularly limited as long as it has portability and information processing capabilities that enable user operation, and is, for example, a tablet, a smartphone, a notebook PC, etc. In the example in the following description, the mobile terminal Md may be configured to have a program that establishes a transmission period of the first sensor device Ea and the second sensor device Eb installed. In this case, the mobile terminal Md can establish a transmission period, etc. based on the user's operation. Note that, when multiple lighting devices L that constitute the management system A1 are installed in a wide area, multiple mobile terminals Md may be provided.

[0050] 5 is a block diagram of a mobile terminal Md. In this embodiment, the mobile terminal Md includes a display unit 31, a control unit 32, a storage unit 33, a wireless communication unit 35, and a power supply unit 36. Here, the construction of a transmission cycle includes a process in which the control unit 32 executes a program to generate a new transmission cycle. The construction of a transmission cycle also includes a process in which a plurality of transmission cycles prepared in advance are stored in the storage unit 33, and the control unit 32 selects a transmission cycle that matches a condition, etc., from these transmission cycles. In the following description, unless otherwise specified, the construction of a transmission cycle is used to include these processes.

[0051] The display unit 31 is for displaying information and images necessary for operating the mobile terminal Md. The display unit 31 is, for example, a liquid crystal display or an organic EL display, and has a touch panel function in this embodiment. Note that instead of the display unit 31 functioning as a touch panel, the mobile terminal Md may also be provided with a separate operating device such as a keyboard or a mouse.

[0052] The control unit 32 is for controlling each unit of the mobile terminal Md. The specific configuration of the control unit 32 is not particularly limited, and may be, for example, a CPU. The storage unit 33 is for storing information such as programs and setting conditions required for the control of the control unit 32, and may be, for example, a semiconductor memory or a hard disk drive. The storage unit 33 may also store a program for establishing a transmission cycle. Alternatively, the storage unit 33 may store a plurality of transmission cycles prepared in advance.

[0053] The wireless communication unit 35 transmits external information (described later) to, for example, the setting device CL via a public network (Internet). The wireless communication unit 35 also receives a request signal from the setting device CL. The frequency band of the wireless communication unit 35 and the wireless communication standard to which it conforms may be the same as or different from those of the first wireless communication unit 141 and the wireless communication unit 24 described above, and for example, Wi-Fi (registered trademark) is selected. The wireless communication unit 35 may be a wireless communication module built into a tablet or the like as the mobile terminal Md, or may be an external wireless communication module connected to a USB terminal or the like.

[0054] The power supply unit 36 ​​is for supplying power necessary for the operation of the display unit 31, the control unit 32, the wireless communication unit 35, etc. The power supply unit 36 ​​is, for example, a rechargeable battery.

[0055] Next, the operation of the management system A1 will be described below.

[0056] As an example of the operation of the management system A1, a case will be described in which a plurality of first sensor devices Ea are installed outside a warehouse and a plurality of second sensor devices Eb are installed inside the warehouse.

[0057] First, the wireless communication network Cn1 shown in FIG. 1 is constructed. In constructing the wireless communication network Cn1, for example, the identification addresses of the plurality of lighting devices L (relay units) are determined using the mobile terminal Md. The mobile terminal Md constructs an identification signal including a MAC address and an identification address, which are unique information, for each of the plurality of lighting devices L (relay units), and transmits the identification signal from the wireless communication unit 54 to each of the lighting devices L (relay units). Alternatively, the control device Ct may receive the identification signal transmitted from the mobile terminal Md, and the control device Ct may transmit the identification signal to the plurality of lighting devices L. Next, in each lighting device L (relay unit), the first wireless communication unit 141 of the wireless communication module 14 receives the identification signal and transfers the identification signal to the control unit 12. The control unit 12 that has received the identification signal stores the identification address in each storage unit 13. As a result, the wireless communication network Cn1 is constructed by the control device Ct and the plurality of lighting devices L. Note that the construction of the identification signal includes a process of generating a new identification signal. Also, the construction of the identification signal includes a process of selecting an identification signal that matches a condition, etc., from a plurality of identification signals generated in advance. In the following description, unless otherwise specified, the construction of an identification signal is used to include these processes.

[0058] Also, after the wireless communication network Cn1 is constructed, the time information may be synchronized. The synchronization of the time information is performed for the control device Ct and the multiple lighting devices L (relay units) constituting the wireless communication network Cn1. Specifically, a clock unit (not shown) transmits the time information, and the control device Ct receives it. The control device Ct creates time data by converting the time information into a first protocol, and transmits it to the multiple lighting devices L (relay units) via the wireless communication network Cn1. The lighting devices L1 to Ln that receive the time information synchronize their own time with the time data, and also transfer the time data to the next lighting device L. Also, each lighting device L may convert the time data into a second protocol and transmit it to the corresponding first sensor device Ea and second sensor device Eb. The first sensor device Ea and second sensor device Eb that receive the time information have the control unit 42 perform time synchronization processing.

[0059] Next, as shown in FIG. 6, the setting device CL requests the designated information (step S1). The designated information is information including information used to determine the transmission cycle of the first sensor device Ea and the second sensor device Eb. An example of the designated information is external information including precipitation probability information. Another example of the designated information is information including the transmission cycle determined by the mobile terminal Md. When the designated information is external information, the external information includes precipitation probability information throughout the day at the point set by the user (precipitation probability information in the morning (0:00 to 12:00) and precipitation probability information in the afternoon (12:00 to 24:00)). In this case, the setting device CL acquires the external information from an information providing site on the Web or the like via a public network (Internet) (step S2). When the designated information is information including the transmission cycle determined by the mobile terminal Md, the designated information is transmitted from the mobile terminal Md to the setting device CL via the public network (Internet) (step S2). The mobile terminal Md may determine the transmission period according to the number of the first sensor devices Ea and the second sensor devices Eb, for example. That is, when the number of the first sensor devices Ea and the second sensor devices Eb is small, the transmission period is set to be short, and when the number of the first sensor devices Ea and the second sensor devices Eb is large, the transmission period is set to be long.

[0060] Next, in step S3, the communication unit 63 of the setting device CL receives the designation information. The control unit 61 stores the designation information in the storage unit 62. The control unit 61 reads out the designation information stored in the storage unit 62 and determines the transmission period of the first sensor device Ea and the transmission period of the second sensor device Eb. The method of determining the transmission period is not limited. When the designation information includes the transmission period determined by the mobile terminal Md, the control unit 61 constructs a setting command including this transmission period. When the designation information includes external information, the control unit 61 determines the transmission period by referring to a transmission period determination table as illustrated in FIG. 16. The transmission period determination table is a table in which the correspondence between precipitation probability information and the transmission period is set. In the example of FIG. 17, a transmission period is set for each combination of the probability of precipitation in the morning and the probability of precipitation in the afternoon. The control unit 61 constructs a setting command including the determined transmission period. Then, the control unit 61 transmits a public network (Internet) setting command from the communication unit 63 to the control device Ct.

[0061] Next, in step S4, the wireless communication unit 24 of the control device Ct receives the setting command. The setting command is transmitted to the control unit 22. The control unit 22 converts the setting command into the first protocol and transfers it to the multiple lighting devices L via the wireless communication network Cn1. The wireless communication modules 14 of the multiple lighting devices L receive the transferred setting command. The control unit 12 transfers the setting command from the wireless communication module 14 to the adjacent lighting device L. As a result, the setting command is transferred to all lighting devices L constituting the wireless communication network Cn1.

[0062] Next, in step S5, the setting command is converted into the second protocol in each lighting device L. Then, the setting command is transmitted to the first sensor device Ea and the second sensor device Eb corresponding to each lighting device L. It is not necessary that all lighting devices L are compatible with both the first sensor device Ea and the second sensor device Eb. For example, one lighting device L may be compatible only with the first sensor device Ea or only with the second sensor device Eb.

[0063] Next, in step S6, in the first sensor device Ea and the second sensor device Eb, the wireless communication unit 44 receives a setting command for the second protocol. The setting command is transmitted to the control unit 42. The control unit 42 stores the transmission cycle included in the setting command in the storage unit 43. The control unit 42 sets the transmission cycle of the transmission by the wireless communication unit 44 to the transmission cycle stored in the storage unit 43.

[0064] 7, the first sensor device Ea installed outside the warehouse (outdoors) measures temperature and humidity using the sensor unit 41 at the above-mentioned measurement period. The control unit 42 constructs measurement data 1 including the temperature and humidity measurement results by the sensor unit 41, a device ID, and a timestamp, and transmits the measurement data 1 to the corresponding lighting device L in the second protocol from the wireless communication unit 44 at the transmission period set at step S6.

[0065] In step S8, the second sensor device Eb installed in the warehouse (indoors) measures the temperature using the sensor unit 41 at the above-mentioned measurement period. The control unit 42 creates measurement data 2 including the temperature and humidity measurement results by the sensor unit 41, a device ID, and a timestamp, and transmits the data from the wireless communication unit 44 to the corresponding lighting device L in the second protocol at the transmission period created in step S6.

[0066] Next, in step S9, the lighting device L corresponding to each of the first sensor devices Ea or each of the second sensor devices Eb among the multiple lighting devices L constituting the wireless communication network Cn1 detects that the measurement data 1 or the measurement data 2 is in the second protocol, and receives the measurement data 1 or the measurement data 2 by the wireless communication module 14. The lighting device L converts the measurement data 1 or the measurement data 2 into the first protocol, and transfers the measurement data 1 or the measurement data 2 via the wireless communication network Cn1.

[0067] Next, in step S10, the wireless communication unit 24 of the control device Ct receives the measurement data 1 and the measurement data 2 transferred via the wireless communication network Cn1. For example, the control unit 22 reads the measurement time from the timestamp included in the measurement data 1 and the measurement data 2 received by the wireless communication unit 24. The control unit 22 also reads the measurement results of temperature and humidity included in the measurement data 1 and the measurement data 2 received by the wireless communication unit 24. The control unit 22 then converts the measurement data 1 and the measurement data 2 into a protocol (for example, Wi-Fi (registered trademark)) for transmitting to the setting device CL, and transmits the measurement data from the wireless communication unit 24 to the setting device CL.

[0068] Next, in step S11, the communication unit 63 of the setting device CL receives the measurement data 1 and the measurement data 2 from the control device Ct via a public network (Internet). The control unit 61 stores the device ID, time stamp, and the measurement results of temperature and humidity contained in the measurement data 1 and the measurement data 2 in the storage unit 62. Then, the control unit 61 calculates the dew point temperature based on the information stored in the storage unit 62. The method of calculating the dew point temperature is not limited in any way.

[0069] For example, FIG. 8 shows a dew-point temperature table used in an example of the calculation process of the dew-point temperature. The illustrated dew-point temperature table is created in advance based on a general dew-point temperature conversion table, and is stored in, for example, the storage unit 62. The control unit 61 can calculate the dew-point temperature by applying the measurement results of the temperature and humidity stored in the storage unit 62 to the dew-point temperature table. For example, when the measurement result (measurement data 1) of the first sensor device Ea installed outside the warehouse (outdoors) is 25°C and the humidity is 60%, the dew-point temperature is calculated to be 16.7°C. Then, the control unit 61 compares the temperature of the measurement result (measurement data 2) of the second sensor device Eb installed inside the warehouse (indoors) with the calculated dew-point temperature. When the temperature inside the warehouse is lower than the dew-point temperature of 16.7°C, it is estimated that there is a high possibility that condensation will occur, and when the temperature inside the warehouse is higher than the dew-point temperature of 16.7°C, it is estimated that there is a low possibility that condensation will occur.

[0070] Next, in step S12, the condensation prediction result is notified in a notification pattern selected according to the prediction result of condensation occurrence in step S11. Fig. 9 shows an example of a notification pattern of the condensation prediction result. In the figure, a notification screen is displayed on a display device Dp. The display device Dp is a display of a PC placed in the office of a user of the management system A1, a digital signage connected to a public network (Internet), or the like. In addition, the mobile terminal Md may also function as the display device Dp.

[0071] The display device Dp has a display unit 71. The display unit 71 is, for example, a liquid crystal display. The control unit 61 of the setting device CL transmits display data of a notification pattern corresponding to the estimation result of condensation to the display device Dp via, for example, a public network (Internet). The display device Dp displays the received notification pattern on the display unit 71.

[0072] The notification pattern shown in Fig. 1(a) is a case where it is estimated that condensation may occur. For example, the difference between the dew-point temperature calculated from the measurement data 1 (the measurement result of the first sensor device Ea) and the temperature of the measurement data 2 (the second sensor device Eb) is in the range of 1°C to 2°C.

[0073] The notification pattern shown in Fig. 1(b) is a case where the possibility of condensation occurring is estimated to be higher than in Fig. 1(a). For example, the difference between the dew-point temperature calculated from measurement data 1 (the measurement result of the first sensor device Ea) and the temperature of measurement data 2 (the second sensor device Eb) is in the range of 0°C to 1°C.

[0074] The notification pattern shown in Fig. 1(c) is a case where condensation is suspected to have occurred, for example, when the temperature of measurement data 2 (the second sensor device Eb) is equal to or lower than the dew point temperature calculated from measurement data 1 (the measurement result of the first sensor device Ea).

[0075] Next, the operation of the management system A1 will be described.

[0076] According to this embodiment, a setting command including the transmission period determined in step S3 shown in FIG. 6 is constructed, and this setting command is transmitted to the first sensor device Ea and the second sensor device Eb. The first sensor device Ea and the second sensor device Eb transmit measurement data at the transmission period included in the setting command. Therefore, for example, it is possible to appropriately determine the transmission period according to the number of the first sensor devices Ea and the second sensor devices Eb. Therefore, it is possible to avoid excessive transmission of measurement data from the first sensor devices Ea and the second sensor devices Eb, and the traffic volume of the wireless communication network can be suppressed.

[0077] 10 to 23 show other embodiments of the present invention. In these figures, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as those in the above embodiment.

[0078] <Second embodiment> 10 to 14 show the operation of the management system according to the second embodiment of the present invention. In this embodiment, in step S21 shown in FIG.

[0079] 11 shows an example of the transmission cycle construction process in step S21. In this example, in step S211, it is determined whether construction of a transmission cycle has been selected by a touch operation on the display unit 31 of the mobile terminal Md or the like. If construction of a transmission cycle has not been selected (step S211: No), step S211 is executed again. If construction of a transmission cycle has been selected (step S211: Yes), in step S212, the control unit 32 checks the current date. To check the date, for example, an RTC function that the mobile terminal Md is equipped with is used.

[0080] Next, in step S213, the calendar table is compared with the current date confirmed in step S212. The calendar table is, for example, a table exemplified in FIG. 12. This calendar table is stored in advance in the storage unit 33 of the mobile terminal Md. In the calendar table, the transmission cycle of the first sensor device Ea and the second sensor device Eb is set based on the weather characteristics of each season throughout the year, for example. That is, the transmission cycle is set according to the case where the precipitation probability information of the weather of the day switches from the first prediction (rain, rainfall) to the second prediction (sunny, sunny weather) and the case where the precipitation probability information of the weather of the day is only the first prediction (rain, rainfall). In more detail, in the rainy season (when there is little change in the weather) such as May and June, when the amount of rainfall throughout the day is more than other months, a longer transmission cycle (second transmission cycle) is set compared to other months. This is based on the characteristic that condensation is less likely to occur when rain continues throughout the day, such as in the rainy season. On the other hand, for months such as July and August, when the weather changes from rain to clear skies more frequently and the temperature and humidity increase with such weather changes (when showers are more likely to occur), a shorter transmission cycle (first transmission cycle) is set than for other months. In other words, such periods are considered to be times when condensation is more likely to occur. A recommended transmission cycle value is obtained by comparing the calendar table with the current date confirmed in step S212.

[0081] Next, in step S214, the recommended transmission cycle as a result of step S213 is displayed, for example, on the display unit 31 of the mobile terminal Md. Next, in 215, it is determined whether the transmission cycle has been determined based on the recommended transmission cycle. For example, while the recommended transmission cycle is displayed on the display unit 31, the user touches an icon such as "OK" or "Back" that is also displayed on the display unit 31. If the transmission cycle has been determined based on the recommended transmission cycle, for example, by selecting the "OK" icon (step S215: Yes), the control unit 32 constructs a setting command including this transmission cycle (step S216). On the other hand, if the transmission cycle has not been determined based on the recommended transmission cycle, for example, by selecting the "Back" icon (step S215: No), for example, step S211 is executed again.

[0082] In step S217, the setting command constructed in step S216 is transmitted to the wireless communication unit 34. The wireless communication unit 34 transmits the setting command to the setting device CL (step S22 in FIG. 10). After that, steps S23 to S25 in FIG. 10 are executed. Steps S23 to S25 are the same processes as steps S4 to S6 described with reference to FIG. 6, for example.

[0083] This embodiment can also suppress communication failure. As described with reference to Fig. 12, in this embodiment, by using a calendar table, it is possible to set the transmission cycle shorter in periods when condensation is likely to occur and longer in periods when condensation is unlikely to occur, based on seasonal trends in temperature and humidity. This improves the accuracy of condensation prediction and reduces the power required to operate the first sensor device Ea and the second sensor device Eb.

[0084] 13 shows another example of the process of establishing a transmission cycle (step S21) of the management system according to the second embodiment. In this example, in step S221, it is determined whether or not the establishment of a transmission cycle is selected, similar to step S211, and if step S221: Yes, in step S222, the current date is confirmed, similar to step S212.

[0085] Next, in step S223, the time schedule is displayed on the display unit 31. The time schedule is a table in which the period from 0:00 to 24:00 on a target day is divided into, for example, hourly frames. The transmission cycle of the first sensor device Ea and the second sensor device Eb can be input and set for each time frame. The user selects the time frame for which the transmission cycle is to be input, for example, by touching the display unit 31. Next, the user inputs the numerical value of the transmission cycle to be set for the selected time frame from a virtual keyboard or the like displayed on the display unit 31. If the transmission cycles for all time frames have been determined (step S224: Yes), the control unit 32 constructs a setting command including the transmission cycle (step S225). If the transmission cycle for any time frame has not been determined (step S224: No), step S224 is executed again.

[0086] In step S226, the setting command constructed in step S225 is transmitted to the wireless communication unit 34. The wireless communication unit 34 transmits the setting command to the setting device CL (step S22 in FIG. 10). After this, steps S23 to S25 in FIG. 10 are executed.

[0087] This embodiment also makes it possible to prevent communication failures. Furthermore, the user can determine the desired length of the transmission cycle with a simpler operation.

[0088] FIG. 14 shows yet another example of the construction process (step S21) of the transmission cycle of the management system according to the second embodiment. In this example, in step S231, the date to be set is displayed in the upper left area of ​​the display unit 31. In addition, in step S232, weather forecast information for the current day, the next day, and the day after that is displayed in the upper right area of ​​the display unit 31 as reference information. For example, the weather forecast information may be information acquired by the mobile terminal Md from an information providing site via a public network (Internet). A general calendar screen is displayed on the display unit 31. The user can select any date as the date to be set by performing a touch operation (slide operation, etc.) on the display unit 31. The user inputs the transmission cycle for each time frame with the desired date displayed.

[0089] This example also makes it possible to suppress communication failure, and allows the user to determine the desired length of the transmission cycle with a simpler operation.

[0090] <Third embodiment> 15 to 17 show a process of constructing a transmission cycle of a management system according to a third embodiment of the present invention. In this embodiment, a process of collecting precipitation probability information shown in FIG. 15 is performed. In this process, the setting device CL acquires precipitation probability information for a location set by a user via a public network (Internet). The precipitation probability information may be, for example, the probability of precipitation in the morning (0:00 to 12:00) and the probability of precipitation in the afternoon (12:00 to 24:00). In addition, it is preferable to acquire the latest information on the probability of precipitation in the morning and the probability of precipitation in the afternoon. For example, the acquisition time is set to acquire the probability of precipitation in the morning at 23:55 and the probability of precipitation in the afternoon at 11:55.

[0091] In the flowchart shown in FIG. 15, in step S31, it is determined whether the set time has been reached. If the set time has not been reached (step S31: No), step S31 is executed again. If the set time has been reached (step S31: Yes), precipitation probability information for the set location is acquired in step S32. The precipitation probability information is acquired, for example, from an information providing site via a public network (Internet). Next, in step S33, the control unit 61 stores the precipitation probability information in the memory unit 62. Through the above steps, the process of collecting precipitation probability information is completed.

[0092] Next, a process of establishing a transmission cycle is performed as shown in Fig. 16. In step S34, the control unit 61 reads out the precipitation probability information stored in the storage unit 62. Next, in step S35, the transmission cycle is determined by comparing the morning precipitation probability and the afternoon precipitation probability with the transmission cycle determination table 1.

[0093] FIG. 17 shows an example of the transmission period determination table 1. The transmission period determination table 1 is a table in which a combination of the probability of precipitation in the morning and the probability of precipitation in the afternoon is associated with a transmission period. For example, when the probability of precipitation in the morning and the probability of precipitation in the afternoon are both 50% or more (first prediction), the transmission period is determined to be 0, and the first sensor device Ea and the second sensor device Eb are not set to transmit. That is, when the value of the transmission period is 0, the transmission period corresponds to the infinitely long second transmission period. Also, when rain is predicted throughout the day (first prediction), the transmission period is set to be longer (second transmission period) than when rain is not predicted throughout the day (for example, 4 hours). When rain is predicted throughout the day, condensation is very unlikely to occur. Therefore, the power consumption associated with transmission by the first sensor device Ea and the second sensor device Eb can be suppressed, and power can be appropriately managed.

[0094] On the other hand, when the probability of precipitation in the morning is 50% or more (first prediction) and the probability of precipitation in the afternoon is close to 0% (second prediction), it is a case where there is a high possibility that the weather will change from rain to sunny during the day. In this case, the transmission cycle is set to the second transmission cycle, which is shorter than when the weather does not change from rain to sunny. This is to predict condensation at shorter intervals and at an earlier stage in a situation where condensation is likely to occur. Furthermore, when the external information includes precipitation probability information of 0% probability of precipitation throughout the day (second prediction), the control unit 61 sets the transmission cycle to the second transmission cycle.

[0095] After determining the transmission cycle in step S35, in step S36, the control unit 61 constructs a setting command including the transmission cycle. Next, in step S37, the control unit 61 transmits the setting command to the communication unit 63. The communication unit 63 transmits the setting command to the control device Ct. Through the above steps, the process of constructing the transmission cycle is completed.

[0096] This embodiment can also suppress communication failures. In addition, when condensation is unlikely to occur, it is possible to determine a long transmission cycle, which suppresses power consumption associated with transmission by the first sensor device Ea and the second sensor device Eb and allows appropriate power management. In addition, when condensation is likely to occur, it is possible to determine a short transmission cycle, which allows condensation to be predicted at an earlier stage. In this embodiment, such a transmission cycle can be determined objectively and rationally based on precipitation probability information included in external information, without relying on the user's judgment.

[0097] <Fourth embodiment> 18 to 20 show a process of constructing a transmission cycle of a management system according to a fourth embodiment of the present invention. In this embodiment, a process of collecting precipitation probability information, temperature information, and humidity information shown in FIG. 17 is performed. In this embodiment, the setting device CL acquires precipitation probability information, temperature information, and humidity information of a point set by a user via a public network (Internet). The precipitation probability information includes, for example, the probability of precipitation in the morning (0:00 to 12:00) and the probability of precipitation in the afternoon (12:00 to 24:00). The temperature information and humidity information include temperature and humidity predictions every six hours. The temperature information and humidity information may be acquired every hour, for example.

[0098] In step S41 shown in FIG. 18, it is determined whether the set time has been reached. If the set time has not been reached (step S41: No), step S41 is executed again. If the set time has been reached (step S41: Yes), precipitation probability information, temperature information, and humidity information for the set point are acquired in step S42. The precipitation probability information, temperature information, and humidity information are acquired, for example, from an information providing site via a public network (Internet). Next, in step S43, the control unit 61 stores the precipitation probability information, temperature information, and humidity information in the memory unit 62. Through the above steps, the process of collecting precipitation probability information is completed.

[0099] Next, a process of establishing a transmission cycle is performed as shown in Fig. 19. In step S44, the control unit 61 reads out the precipitation probability information, temperature information, and humidity information stored in the storage unit 62. Next, in step S45, the precipitation probability information, temperature information, and humidity information are compared with the transmission cycle determination table 2 to determine the transmission cycle.

[0100] 20 shows an example of the transmission cycle determination table 2. The transmission cycle determination table 2 is a table in which the probability of precipitation, temperature, and humidity in the morning and the probability of precipitation, temperature, and humidity in the afternoon are associated with the transmission cycle.

[0101] Condensation is highly likely to occur when the weather changes from rain to clear during the day, and further when the temperature changes and the humidity is high. For this reason, the transmission cycle determination table 2 determines the transmission cycle to be a short interval of, for example, 5 minutes (first transmission cycle) when the external information includes precipitation probability information of a first prediction in which the probability of precipitation in the morning is 50% or more and there is a high probability of rain, and includes precipitation probability information of a second prediction in which the probability of precipitation in the afternoon is 0% and there is a very high probability of clear weather, and further includes predictions of a morning temperature of 15°C, a humidity of 90%, and an afternoon temperature of 25°C, a humidity of 50%. Moreover, this temperature change also includes a temperature change from a high temperature to a low temperature (for example, from 20°C to 10°C). Condensation is also likely to occur in such cases. In this example, high humidity is 50% or more.

[0102] On the other hand, when precipitation probability information is obtained in which the second prediction that the weather will be sunny during the day continues, when the weather changes from cloudy to sunny, when the temperature change between morning and afternoon is small (for example, when the temperature change is 2°C or less), or when the humidity change between morning and afternoon is small (for example, when the humidity change is 10% or less), the control unit 61 determines the transmission period to be a long period such as 2 hours (the second transmission period). That is, when the external information includes precipitation probability information that switches from the first prediction to the second prediction during the day, the control unit 61 sets the transmission period to the first transmission period, and when the external information includes precipitation probability information of only the first prediction during the day, the control unit 61 sets the transmission period to the second transmission period. Furthermore, the transmission period may be changed when the temperature change or humidity change during the day is small and when the temperature change is large. Moreover, the first prediction and the second prediction are not limited to being defined based only on the precipitation probability information, and may be defined based on the precipitation probability information, temperature information, and humidity information. In the above example, the first prediction may be external information such as a 50% probability of precipitation, a temperature of 15°C, and a humidity of 90%, while the second prediction may be external information such as a 0% probability of precipitation, a temperature of 25°C, and a humidity of 50%.

[0103] 19, in step S46, the control unit 61 creates a setting command including the transmission cycle. Next, in step S47, the control unit 61 transmits the setting command to the communication unit 63. The communication unit 63 transmits the setting command to the control device Ct. Through the above steps, the process of creating the transmission cycle is completed.

[0104] This embodiment can also suppress communication failures. Moreover, compared to transmission period determination table 1, transmission period determination table 2 determines the transmission period based on temperature information and humidity information in addition to precipitation probability information. This contributes to predicting the occurrence of condensation with higher accuracy. Furthermore, in cases where condensation is unlikely to occur, a longer transmission period is determined, thereby suppressing power consumption associated with transmission by the first sensor device Ea and the second sensor device Eb, and allowing for appropriate power management.

[0105] <Fifth embodiment> 21 to 23 show the operation of the management system according to the fifth embodiment of the present invention. In this embodiment, in step S51 shown in FIG. 21, designation information is requested, similar to step S1 in FIG. 6. In step S52, the designation information is transmitted to the setting device CL, similar to step S2. In step S53, similar to step S3, the transmission cycle is determined by referring to the transmission cycle determination table, and a setting command is constructed and transmitted. Also in step S53, the control unit 61 stores the designation information in the storage unit 62. In this embodiment, the above-mentioned external information (including temperature information and humidity information) is stored in the storage unit 62 as the designation information. Thereafter, in steps S54 to S56, the same processes as those in steps S4 to S6 described above are performed.

[0106] Next, in steps S61 to S64 shown in Fig. 22, the same processes as in steps S7 to S10 in Fig. 7 are performed. Next, in step S65, the control unit 61 defines the temperature information and humidity information included in the external information stored in the storage unit 62 as first information. Also, the temperature information and humidity information that are the measurement results of the first sensor device Ea are defined as second information.

[0107] 23 is a flowchart showing an example of a comparison process between the first information and the second information. In this example, in step S71, it is confirmed whether the communication unit 63 has received the measurement data 1 from the first sensor device Ea. If the measurement data 1 has not been received (step S71: No), step S71 is executed again. If the measurement data 1 has been received (step S71: Yes), in step S72, the control unit 61 of the setting device CL reads out the first information stored in the memory unit 62.

[0108] Next, in step S73, the control unit 61 compares the temperature and humidity of the first information with the temperature and humidity of the second information. If the temperature difference between the temperature of the first information and the temperature of the second information is within 1°C and the humidity difference between the humidity of the first information and the humidity of the second information is within 5% (step S73: Yes), the control unit 61 ends the comparison process between the first information and the second information. On the other hand, if at least one of the following is true: the temperature difference between the temperature of the first information and the temperature of the second information is greater than 1°C and the humidity difference between the humidity of the first information and the humidity of the second information is greater than 5% (step S73: No), in step S74, the control unit 61 refers to the above-mentioned transmission period determination table 2 based on the second information to determine the transmission period.

[0109] Next, a setting command including this transmission cycle is constructed (step S75). In step S76, the control unit 61 transmits the setting command to the communication unit 63. Thereafter, by performing processes similar to those of steps S53 to S62, for example, the setting command is transmitted and transferred, and measurements are performed by the first sensor device Ea and the second sensor device Eb, and the measurement data is transmitted.

[0110] This embodiment can also suppress communication failures. Even if the temperature and humidity forecasts acquired as external information are incorrect, the power consumption associated with transmission by the first sensor device Ea and the second sensor device Eb can be appropriately managed.

[0111] The management system according to the present invention is not limited to the above-described embodiment, and the specific configuration of each part of the management system according to the present invention can be freely designed in various ways. [Explanation of symbols]
