Modes for Carrying Out the Invention

[0012] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, common elements are denoted by the same reference numerals, and redundant descriptions of the common elements may be omitted. Note that the following embodiments and modifications are only a part of various embodiments of the present disclosure. Further, the following embodiments and modifications can be variously changed according to design and the like as long as the object of the present disclosure can be achieved. Also, the configurations of the following Embodiment 1, Embodiment 2, and modifications can be appropriately combined.

[0013] Each drawing described in the present disclosure is a schematic diagram, and the ratio of the size and thickness of each component in each drawing does not necessarily reflect the actual dimensional ratio.

[0014] (Embodiment 1) (1) Overview First, the overview of the adjustment system 1 according to Embodiment 1 will be described with reference to FIG. 1.

[0015] The adjustment system 1 is a system for adjusting the first sensor terminal 2. The adjustment system 1 of Embodiment 1 includes a first sensor terminal 2 and a second sensor terminal 3.

[0016] The first sensor terminal 2 is disposed on the construction surface 101 (see FIG. 2) where the lighting fixture 4 is disposed. The first sensor terminal 2 includes a first sensor 22 and a processing unit 24.

[0017] The second sensor terminal 3 is disposed on the irradiation surface 91 (see FIG. 2) irradiated with the illumination light from the lighting fixture 4. The second sensor terminal 3 includes a communication unit 31 and a second sensor 32.

[0018] The first sensor 22 measures the amount of incident light when the lighting fixture 4 is lit.

[0019] The second sensor 32 measures the illuminance of the illumination light on the irradiation surface 91.

[0020] The communication unit 31 of the second sensor terminal 3 periodically transmits the measurement values measured by the second sensor 32.

[0021] The processing unit 24 of the first sensor terminal 2 determines a correction coefficient for controlling the brightness of the illumination light of the lighting fixture 4 based on the measurement value measured by the first sensor 22 and the measurement value measured by the second sensor 32.

[0022] According to the adjustment system 1 of Embodiment 1, since the communication unit 31 periodically transmits the measurement values measured by the second sensor 32 disposed on the irradiation surface 91, for example, compared with the case where an operator operates the sensor to transmit the measurement value of the illuminance measured by the sensor to other sensors or the like, the burden on the operator can be reduced.

[0023] Moreover, the adjustment method according to Embodiment 1 is an adjustment method of the first sensor terminal 2 executed by a computer system (for example, the adjustment system 1).

[0024] The adjustment method includes a first measurement step, a second measurement step, a communication step, and a determination step.

[0025] In the first measurement step, the first sensor terminal 2 disposed on the construction surface 101 where the lighting fixture 4 is installed measures the amount of incident light on the first sensor terminal 2 in a state where the lighting fixture 4 is lit.

[0026] In the second measurement step, the second sensor terminal 3 disposed on the irradiation surface 91 irradiated with the illumination light from the lighting fixture 4 measures the illuminance of the illumination light.

[0027] In the communication step, the measurement value in the second measurement step is transmitted from the second sensor terminal 3 to the first sensor terminal 2.

[0028] In the determination step, a correction coefficient for controlling the brightness of the illumination light of the lighting fixture 4 is determined based on the measurement value in the first measurement step and the measurement value in the second measurement step.

[0029] In the adjustment method, based on a predetermined trigger, a first measurement step, a second measurement step, a communication step, and a determination step are automatically executed.

[0030] Also, the adjustment method of Embodiment 1 is used on a computer system (Adjustment System 1). That is, the adjustment method can also be embodied as a program. A program according to one aspect is a program for causing the computer system to execute the above adjustment method. The program may be recorded on a non-transitory computer-readable recording medium.

[0031] Conventionally, in a lighting system including a lighting fixture and an illuminance sensor, the brightness of the lighting light is controlled based on the amount of incident light on the illuminance sensor so that the illuminance on an irradiation surface such as a desk surface reaches a target value. Also, in the lighting system, an illuminance sensor may be arranged on a construction surface of a lighting fixture such as a ceiling surface. The illuminance sensor arranged on the construction surface cannot directly measure the illuminance on the irradiation surface. Therefore, when installing the lighting system or renovating the interior of a facility such as an office, etc., the adjustment of the illuminance sensor arranged on the construction surface may be performed. The adjustment of the illuminance sensor is performed by measuring the illuminance on the irradiation surface with another illuminance sensor held by an operator, and obtaining the relationship between the measured value of the amount of incident light measured by the illuminance sensor arranged on the construction surface and the measured value of the illuminance measured by another illuminance sensor.

[0032] Since it is necessary to adjust the illuminance sensor so that the illuminance on an irradiation surface such as a desk surface reaches the target value, the adjustment of the illuminance sensor needs to be performed after the arrangement of furniture such as desks is completed. Also, the adjustment of the illuminance sensor is preferably performed at night or the like when it is less affected by external light. Therefore, when renovating the interior of a facility, etc., the adjustment of the illuminance sensor is performed at night within a short period from the completion of the interior construction and the arrangement of furniture until it is handed over to the customer. Since the workable period is very limited, a large number of personnel may be required for the adjustment of the illuminance sensor, which has been a burden on the operators.

[0033] According to the adjustment method of Embodiment 1, since each step is automatically executed, the work performed by the operator can be reduced, and the burden on the operator can be alleviated. Further, according to the adjustment method of Embodiment 1, it is possible to remotely execute the adjustment method from a location different from the facility 100 such as an office where the adjustment system 1 is installed, and the number of operators working at night can be reduced.

[0034] (2) Details Hereinafter, the detailed configuration of the adjustment system 1 according to Embodiment 1 will be described with reference to FIGS. 1 to 3.

[0035] (2.1) Configuration of the adjustment system The adjustment system 1 of Embodiment 1 is provided in the facility 100. In the present disclosure, the case where the facility 100 is an office is exemplified. The "facility" referred to in the present disclosure includes a residential facility used for residential purposes, and non-residential facilities such as stores (tenants), offices (office buildings), welfare facilities, educational facilities, hospitals, and factories. The non-residential facilities also include restaurants, amusement arcades, gymnasiums, event venues, hotels, inns, kindergartens, nurseries, and community centers. That is, the facility 100 may be a residential facility such as an apartment, or a non-residential facility such as an office. Further, the facility 100 includes a facility in a form in which a residential facility and a non-residential facility are mixed, for example, a facility in which the lower floors are stores and the upper floors are residential units.

[0036] As shown in FIG. 2, in the present disclosure, a case where the adjustment system 1 is provided in one room of the facility 100 is exemplified. FIG. 2 exemplifies one room of the facility 100 at night after the interior construction and the arrangement of furniture are completed. In one room of the facility 100, a plurality (two in the example of FIG. 2) of furniture 9 are arranged. The two furniture 9 include furniture 9a and furniture 9b. The furniture 9a and 9b in Embodiment 1 are desks. The upper surface of the desk which is the furniture 9a is the irradiation surface 91a of the illumination light of the three lighting fixtures 4a to 4c. Also, the upper surface of the desk which is the furniture 9b is the irradiation surface 91b of the illumination light of the three lighting fixtures 4d to 4f. In the following description, when not distinguishing each of the two furniture 9a and 9b, each of the two furniture 9a and 9b may be simply referred to as furniture 9. Also, when not distinguishing each of the two irradiation surfaces 91a and 91b, each of the two irradiation surfaces 91a and 91b may be simply referred to as irradiation surface 91.

[0037] As shown in FIGS. 1 and 2, the adjustment system 1 in Embodiment 1 includes a plurality (two in the example of FIG. 2) of first sensor terminals 2, a plurality (two in the example of FIG. 2) of second sensor terminals 3, a plurality (six in the example of FIG. 2) of lighting fixtures 4, and an operation terminal 5.

[0038] (2.2) Lighting Fixtures As shown in FIG. 2, the plurality of lighting fixtures 4 are arranged on the construction surface 101. The construction surface 101 is the ceiling surface of the facility 100. The plurality of lighting fixtures 4 include a lighting fixture 4a, a lighting fixture 4b, a lighting fixture 4c, a lighting fixture 4d, a lighting fixture 4e, and a lighting fixture 4f. In the following description, when not distinguishing each of the six lighting fixtures 4a to 4f, each of the lighting fixtures 4a to 4f may be simply referred to as lighting fixture 4.

[0039] FIG. 2 illustrates a case where three lighting fixtures 4a to 4c are arranged in a row and three lighting fixtures 4ad to 4f are arranged in a row. The three lighting fixtures 4a to 4c belong to group G1 and have the same group address. The three lighting fixtures 4a to 4c are associated with the first sensor terminal 2a, and the brightness of the illumination light of the three lighting fixtures 4a to 4c is controlled according to the amount of incident light measured by the first sensor terminal 2a. The three lighting fixtures 4d to 4f belong to group G2 and have the same group address. Note that the group address of group G1 and the group address of group G2 are different addresses. The three lighting fixtures 4d to 4f are associated with the first sensor terminal 2b, and the brightness of the illumination light of the three lighting fixtures 4d to 4f is controlled according to the amount of incident light measured by the first sensor terminal 2b.

[0040] As shown in FIG. 1, the lighting fixture 4 includes a communication unit 41, an illumination unit 42, and a control unit 43.

[0041] The communication unit 41 includes a communication interface capable of communicating with the first sensor terminal 2 and a communication interface capable of communicating with the operation terminal 5. In Embodiment 1, the communication method between the communication unit 41 and the first sensor terminal 2 or the operation terminal 5 is wireless communication using radio waves conforming to a communication standard such as a specific low-power radio station in the 920 MHz band, Wi-Fi (registered trademark), or Bluetooth (registered trademark). Note that "capable of communicating" as used in the present disclosure means that information can be exchanged directly or indirectly via a network or a repeater or the like by an appropriate communication method of wired communication or wireless communication.

[0042] For example, the communication unit 41 receives illuminance information from the first sensor terminal 2.

[0043] The illumination unit 42 includes a plurality of LEDs (Light Emitting Diodes) and a power supply circuit or the like, and irradiates illumination light in a predetermined range. The illumination unit 42 irradiates illumination light with a brightness based on the control of the control unit 43.

[0044] The control unit 43 mainly consists of, for example, a computer system having one or more processors and one or more memories. In the lighting fixture 4, the functions of the control unit 43 are realized by one or more processors executing programs recorded in the memory. The program may be pre-recorded in the memory, may be provided through a telecommunication line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.

[0045] The control unit 43 controls the lighting unit 42. The control unit 43 controls the lighting unit 412 so that the illuminance on the irradiation surface 91 becomes the target value based on the amount of incident light on the first sensor 22 measured by the first sensor terminal 2. The control unit 43 of Embodiment 1 controls the lighting unit 412 so that the illuminance on the irradiation surface 91 becomes the target value based on the illuminance information received from the first sensor terminal 2. Here, the target value of the illuminance on the irradiation surface 91 is, for example, 300 lux. However, the target value of the illuminance may be set as appropriate.

[0046] (2.3) Second sensor terminal As shown in FIG. 2, the plurality of second sensor terminals 3 include a second sensor terminal 3a and a second sensor terminal 3b. In the following description, when not distinguishing each of the two second sensor terminals 3a to 3b, each of the two second sensor terminals 3a to 3b may be referred to as the second sensor terminal 3 at the end.

[0047] Each of the plurality of second sensor terminals 3 is arranged on any one of the plurality of irradiation surfaces 91 irradiated with the illumination light from the plurality of lighting fixtures 4. In Embodiment 1, the second sensor terminal 3a is arranged on the irradiation surface 91a, and the second sensor terminal 3b is arranged on the irradiation surface 91b. In Embodiment 1, the second sensor terminal 3a is arranged directly below the first sensor terminal 2a, and the second sensor terminal 3b is arranged directly below the first sensor terminal 2b.

[0048] The second sensor terminal 3 is a portable terminal. In the present disclosure, for example, during daytime or other time periods outside of nighttime, a case is exemplified where the second sensor terminal 3 is pre-arranged on the irradiation surface 91 by a worker performing interior construction work or a worker adjusting the first sensor terminal 2. Further, in the present disclosure, a case is exemplified where the second sensor terminal 3 is removed from the irradiation surface 91 after the adjustment of the first sensor terminal 2 is completed. However, the second sensor terminal 3 may be arranged on the irradiation surface 91 without being removed even after the adjustment of the first sensor terminal 2 is completed.

[0049] As shown in FIG. 1, the second sensor terminal 3 includes a communication unit 31, a second sensor 32, an acceleration sensor 33, and a processing unit 34.

[0050] The second sensor 32 measures the illuminance of the illumination light on the irradiation surface 91 irradiated with the illumination light from the lighting fixture 4. That is, the second sensor 32 executes the second measurement step included in the adjustment method. In the second sensor 32 of Embodiment 1, the second measurement step is periodically executed when the state of the second sensor terminal 3 is the power-on state. In other words, the second measurement step of Embodiment 1 is automatically performed when the state of the second sensor terminal 3 is the power-on state.

[0051] The communication unit 31 includes a communication interface capable of communicating with the first sensor terminal 2. In Embodiment 1, in Embodiment 1, the communication method between the communication unit 31 and the first sensor terminal 2 is wireless communication using radio waves conforming to a communication standard such as a specific low-power radio station in the 920 MHz band, Wi-Fi (registered trademark), or Bluetooth (registered trademark).

[0052] The communication unit 31 executes part of the processing of the communication steps included in the adjustment method. The communication unit 31 in Embodiment 1 periodically transmits measurement information. More specifically, the communication unit 31 periodically broadcasts and transmits the measurement information. The measurement information includes information on the measured value of the illuminance measured by the second sensor 32 in the second measurement step, the identification information of the second sensor terminal 3, and the detection information detected by the acceleration sensor 33. The communication unit 31 in Embodiment 1 periodically broadcasts and transmits the measurement information when the second sensor terminal 3 is in the power-on state. In other words, part of the communication step in Embodiment 1 is automatically performed when the second sensor terminal 3 is in the power-on state. Since the communication unit 31 of the second sensor terminal 3 disposed in advance on the irradiation surface 91 periodically transmits the measurement information, the burden on the operator can be further reduced compared to the case where the operator operates a sensor terminal for adjustment or the like to perform communication.

[0053] The acceleration sensor 33 detects the acceleration of the second sensor terminal 3. The acceleration sensor 33 is, for example, a three-axis acceleration sensor. The three-axis acceleration sensor detects the acceleration for each of the three mutually orthogonal axes and outputs an electrical signal corresponding to the acceleration to the processing unit 34.

[0054] The processing unit 34 mainly includes, for example, a computer system having one or more processors and one or more memories. In the second sensor terminal 3, the functions of the processing unit 34 are realized by one or more processors executing programs recorded in the memory. The program may be recorded in the memory in advance, may be provided through an electrical communication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card.

[0055] The processing unit 34 performs various processes such as controlling the communication unit 31.

[0056] (2.4) First sensor terminal As shown in FIG. 2, the plurality of first sensor terminals 2 include a first sensor terminal 2a and a first sensor terminal 2b. In the following description, when not distinguishing each of the two first sensor terminals 2a to 2b, each of the two first sensor terminals 2a to 2b may be referred to as the first sensor terminal 2 at the end.

[0057] The first sensor terminal 2 is arranged on the construction surface 101 where the lighting fixture 4 is arranged. The first sensor terminal 2a is arranged adjacent to three lighting fixtures 4a to 4c on the construction surface 101, and the first sensor terminal 2b is arranged adjacent to three lighting fixtures 4d to 4f on the construction surface 101. "Adjacent" includes that the distance between the two is equal to or less than a predetermined distance. The predetermined distance is, for example, 3 m. However, the predetermined distance may be set as appropriate.

[0058] The first sensor terminal 2 is associated with one or more lighting fixtures 4 included in the plurality of lighting fixtures 4. As described above, the first sensor terminal 2a is associated with three lighting fixtures 4a to 4c, and the first sensor terminal 2b is associated with three lighting fixtures 4d to 4f.

[0059] As shown in FIG. 1, the first sensor terminal 2 includes a communication unit 21, a first sensor 22, a storage unit 23, and a processing unit 24.

[0060] The communication unit 21 includes a communication interface capable of communicating with the second sensor terminal 3, a communication interface capable of communicating with the lighting fixture 4, and a communication interface capable of communicating with the operation terminal 5. In Embodiment 1, the communication method between the communication unit 21 and the first sensor terminal 2, the second sensor terminal 3, or the operation terminal 5 is, for example, wireless communication using radio waves in accordance with a communication standard such as a specific low-power radio station in the 920 MHz band, Wi-Fi (registered trademark), or Bluetooth (registered trademark).

[0061] For example, the communication unit 21 of Embodiment 1 receives a trigger signal from the operation terminal 5. Also, the communication unit 21 receives measurement information from the second sensor terminal 3. Further, the communication unit 21 transmits illuminance information to one or more lighting fixtures 4 belonging to the same group as the first sensor terminal 2. That is, the first sensor terminal 2a transmits illuminance information to the three lighting fixtures 4a to 4c belonging to the group G1. Also, the first sensor terminal 2b transmits illuminance information to the three lighting fixtures 4d to 4f belonging to the group G2.

[0062] The communication unit 21 of Embodiment 1 executes part of the processing of the communication step included in the adjustment method. More specifically, the communication unit 21 periodically receives the measurement information transmitted by the second sensor terminal 3. Also, the communication unit 21 of Embodiment 1 periodically receives the measurement information transmitted by the second sensor terminal 3 when the first sensor terminal 2 is in the powered-on state. In other words, part of the communication step of Embodiment 1 is automatically performed when the first sensor terminal 2 is in the powered-on state.

[0063] The first sensor 22 is a sensor that measures (or detects) the amount of light incident from within the detection range (or incident light amount). That is, the first sensor 22 executes the first measurement step included in the adjustment method. In FIG. 2, the hatched area A1 represents the detection range of the first sensor 22 of the first sensor terminal 2a, and the hatched area A2 represents the detection range of the first sensor 22 of the first sensor terminal 2b. The first sensor 22 has a photodiode, a phototransistor, or the like. Note that the first sensor 22 may be able to measure illuminance.

[0064] Note that the first sensor 22 of Embodiment 1 periodically executes the first measurement step when the first sensor terminal 2 is in the powered-on state. In other words, the first measurement step of Embodiment 1 is automatically performed when the first sensor terminal 2 is in the powered-on state.

[0065] The storage unit 23 is a semiconductor memory such as a ROM (Read Only Memory), a RAM (Random Access Memory), or an EEPROM (Electrically Erasable Programmable Read Only Memory).

[0066] The storage unit 23 stores the identification information of the first sensor terminal 2, the identification information of the lighting fixture 4 associated with the first sensor terminal 2, and the group address of the group to which the first sensor terminal 2 belongs. Further, the storage unit 23 stores the correction coefficient determined by the processing unit 24 and the correction formula for adjusting the incident light amount (or illuminance) measured by the first sensor terminal 2.

[0067] The processing unit 24 mainly includes, for example, a computer system having one or more processors and one or more memories. In the first sensor terminal 2, the functions of the processing unit 24 are realized by one or more processors executing the programs recorded in the memory. The program may be recorded in the memory in advance, may be provided through an electric communication line such as the Internet, or may be provided by being recorded in a non-temporary recording medium such as a memory card.

[0068] The processing unit 24 of the first embodiment executes one or more of the plurality of processes included in the adjustment method.

[0069] The processing unit 24 executes the above-described determination step included in the adjustment method. That is, in the first embodiment, the determination step included in the adjustment method is executed by the first sensor terminal 2. The processing unit 24 determines a correction coefficient for controlling the brightness of the illumination light of the lighting fixture 4 based on the measurement value in the first measurement step and the measurement value in the second measurement step. The information of the measurement value in the first measurement step is output from the first sensor 22, and the information of the measurement value in the second measurement step is included in the measurement information received by the communication unit 21. The processing unit 24 determines the correction coefficient by the following formula (1).

[0070] Y = A × X (1)

[0071] Here, "Y" in formula (1) is the measured value in the first measurement step. Also, "A" in formula (1) is a correction coefficient. Further, "X" in formula (1) is the measured value in the second measurement step.

[0072] The processing unit 24 of Embodiment 1 determines a correction coefficient based on the measured value in the first measurement step and the measured value measured by the second sensor terminal 3 associated with the first sensor terminal 2 in the selection step described later. As will be described later, in the adjustment method of Embodiment 1, since the second sensor terminal 3 corresponding to the first sensor terminal 2 is selected based on the received radio wave intensity in the selection step, the operator does not need to perform the work of associating the sensor terminal with the first sensor terminal 2, and the burden on the operator can be further reduced.

[0073] After the adjustment of the first sensor terminal 2 is completed, the processing unit 24 of Embodiment 1 periodically transmits illuminance information to the lighting fixture 4 corresponding to the first sensor terminal 2 via the communication unit 21 in the operating state. The illuminance information is information based on the measured value at the first sensor 22 and the determined correction coefficient, and is information for controlling the brightness of the illumination light of the lighting fixture 4 so that the illuminance on the irradiation surface 91 becomes the target value.

[0074] Further, the processing unit 24 executes a radio wave measurement step included in the adjustment method. In the radio wave measurement step, the communication unit 21 receives radio waves from the second sensor terminal 3 and measures the received radio wave intensity. That is, the processing unit 24 measures the received radio wave intensity of the radio waves from the second sensor terminal 3 received by the communication unit 21. In the radio wave measurement step of Embodiment 1, the communication unit 21 receives a plurality of radio waves from a plurality of second sensor terminals and measures a plurality of received radio wave intensities corresponding one-to-one to the plurality of radio waves.

[0075] In addition, the processing unit 24 executes the selection step included in the adjustment method. In the selection step, the second sensor terminal 3 corresponding to the strongest received radio wave intensity among the plurality of received radio wave intensities is selected, and the selected second sensor terminal 3 is associated with the first sensor terminal 2. That is, the processing unit 24 selects the second sensor terminal 3 corresponding to the strongest received radio wave intensity among the plurality of received radio wave intensities measured in the radio wave measurement step, and associates the selected second sensor terminal 3 with the first sensor terminal 2. Note that in the selection step, the received radio wave intensity may be smoothed by a method such as a moving average, and then the second sensor terminal 3 corresponding to the strongest received radio wave intensity among the plurality of received radio wave intensities may be selected.

[0076] In addition, in the selection step, the processing unit 24 determines whether there is a radio wave whose received radio wave intensity is equal to or greater than the intensity threshold among the plurality of radio waves received by the communication unit 21. If there is no radio wave whose received radio wave intensity is equal to or greater than the intensity threshold among the plurality of radio waves received by the communication unit 21, the adjustment system 1 ends the adjustment method.

[0077] In addition, the processing unit 24 executes the timing determination step included in the adjustment method. In the timing determination step, it is determined whether the current time is a predetermined timing. For example, the predetermined timing is a timing when there is no influence of external light or the influence of external light is small enough to be ignored. The predetermined timing is, for example, at night (for example, from 21:00 to 5:00). The processing unit 24 of Embodiment 1 determines whether the current time is a predetermined timing based on the time information included in the trigger signal transmitted from the operation terminal 5. In the timing determination step of Embodiment 1, the processing unit 24 determines that the current time is a predetermined timing when the current time is at night.

[0078] In the adjustment method of Embodiment 1, when it is determined in the timing determination step that the current time is a predetermined timing, the first measurement step, the second measurement step, the communication step, and the determination step are executed. That is, in the adjustment method, when it is determined in the timing determination step that the current time is nighttime, the first measurement step, the second measurement step, the communication step, and the determination step are executed. Thereby, the adjustment of the first sensor terminal 2 can be performed at night.

[0079] Further, the processing unit 24 executes the movement determination step included in the adjustment method. In the movement determination step, the processing unit 24 determines whether or not the second sensor terminal 3 has moved during the execution of the adjustment method. In the movement determination step of Embodiment 1, the processing unit 24 determines that the second sensor terminal 3 has moved when the acceleration detected by the acceleration sensor 33 of the second sensor terminal 3 is equal to or greater than the acceleration threshold value. The processing unit 24 determines whether or not the second sensor terminal 3 has moved based on the detection information included in the measurement information received from the second sensor terminal 3.

[0080] In the adjustment method of Embodiment 1, when the processing unit 24 determines in the movement determination step that the second sensor terminal 3 has moved, the first measurement step, the second measurement step, the communication step, and the determination step are executed again. Thereby, it is possible to reduce the possibility that the second sensor terminal 3 moves for some reason during the adjustment of the first sensor terminal 2 and an inappropriate correction coefficient is determined in the determination step. Further, in the movement determination step of Embodiment 1, since it is determined whether or not the second sensor terminal 3 has moved based on the acceleration detected by the acceleration sensor 33, it is possible to more reliably determine whether or not the second sensor terminal 3 has moved.

[0081] Further, the processing unit 24 executes the variation amount determination step included in the adjustment method. In the variation amount determination step, the processing unit 24 determines whether or not the variation amount of at least one of the measurement value in the first measurement step and the measurement value in the second measurement step is equal to or greater than the variation amount threshold value.

[0082] In the adjustment method of Embodiment 1, when the processing unit 24 determines in the variation amount determination step that the variation amount is equal to or greater than the variation amount threshold value, the first measurement step, the second measurement step, the communication step, and the determination step are executed again.

[0083] When the variation amount of the measurement value in the first measurement step or the measurement value in the second measurement step is large, it is highly likely that the measurement value is not appropriate, and there is a high possibility that a situation will occur in which an inappropriate correction coefficient is determined in the determination step. According to the adjustment method of Embodiment 1, it is possible to reduce the possibility that a situation will occur in which an inappropriate correction coefficient is determined in the determination step.

[0084] (2.5) Operating terminal The operating terminal 5 is a terminal used by an operator when adjusting the first sensor terminal 2. For example, the operating terminal 5 is a tablet terminal installed with an application for adjusting the first sensor terminal 2. Note that the operating terminal 5 may be a smartphone, a personal computer, or the like installed with an application for adjusting the first sensor terminal 2, or may be a dedicated terminal used for adjusting the first sensor terminal 2.

[0085] As shown in FIG. 1, the operating terminal 5 includes a communication unit 51 and a processing unit 52.

[0086] The communication unit 51 includes a communication interface capable of communicating with the first sensor terminal 2. In Embodiment 1, the communication method between the communication unit 51 and the first sensor terminal 2 is wireless communication using radio waves conforming to a communication standard such as a specific low-power radio station in the 920 MHz band, Wi-Fi (registered trademark), or Bluetooth (registered trademark).

[0087] The communication unit 51 transmits a trigger signal to the first sensor terminal 2. The trigger signal is a signal that serves as a predetermined trigger for causing the adjustment system 1 to execute an adjustment method. For example, the communication unit 51 transmits a trigger signal to the first sensor terminal 2 when a predetermined operation is performed on the operating terminal 5 or when a preset predetermined date and time is reached.

[0088] The processing unit 52 mainly consists of, for example, a computer system having one or more processors and one or more memories. In the first sensor terminal 2, the functions of the processing unit 52 are realized by one or more processors executing programs recorded in the memory. The program may be recorded in the memory in advance, may be provided through a telecommunication line such as the Internet, or may be recorded and provided on a non-transitory recording medium such as a memory card.

[0089] (3) Operation of the adjustment system Next, the operation of the adjustment system 1 will be described with reference to FIG. 3. FIG. 3 is a flowchart of an adjustment method executed by the adjustment system 1. The series of processes shown in FIG. 3 is started based on a predetermined trigger. In the first embodiment, the predetermined trigger is that the first sensor terminal 2 receives a trigger signal transmitted by the operation terminal 5. Also, when the adjustment system 1 in the first embodiment starts the series of processes shown in FIG. 3, it periodically executes a first measurement step, a second measurement step, and a communication step.

[0090] The adjustment system 1 executes a radio wave measurement step to determine whether the second sensor terminal 3 exists within a predetermined range around the first sensor terminal 2 (step S1). More specifically, the adjustment system 1 determines that the second sensor terminal 3 exists within the predetermined range when there is a radio wave whose received radio wave intensity is equal to or greater than the intensity threshold. If the adjustment system 1 determines that the second sensor terminal 3 does not exist within the predetermined range (step S1: No), it ends the series of processes.

[0091] If the adjustment system 1 determines that the second sensor terminal 3 exists within the predetermined range (step S1: Yes), it executes a timing determination step to determine whether the current time is a predetermined timing (step S2). If the adjustment system 1 determines that the current time is not the predetermined timing (step S2: No), it ends the series of processes.

[0092] When the adjustment system 1 determines that the current time is a predetermined timing (step S2: Yes), it starts the adjustment of the first sensor terminal 2 (step S3). In the radio wave measurement step executed in step S1, when there are a plurality of radio waves whose received radio wave intensity is equal to or greater than the intensity threshold value, the adjustment system 1 performs a selection step at this timing.

[0093] Next, the adjustment system 1 executes a determination step to determine a correction coefficient (step S4). The adjustment system 1 determines the correction coefficient based on the measurement value in the first measurement step and the measurement value measured by the second sensor terminal 3 associated with the first sensor terminal 2 in the selection step.

[0094] Next, the adjustment system 1 executes a movement determination step to determine whether the second sensor terminal 3 has moved during the adjustment of the first sensor terminal 2 (step S5). When the adjustment system 1 determines that the second sensor terminal 3 has moved (step S5: Yes), it adjusts the first sensor terminal 2 again.

[0095] When the adjustment system 1 determines that the second sensor terminal 3 has not moved (step S5: No), it executes a variation amount determination step to determine whether the variation value of the measurement value in the first measurement step or the variation value of the measurement value in the second measurement step during the adjustment of the first sensor terminal 2 is less than the variation threshold value (step S6). When the adjustment system 1 determines that the variation threshold value is not less than the variation threshold value, that is, when it determines that the variation value is equal to or greater than the variation threshold value (step S6: No), it adjusts the first sensor terminal 2 again.

[0096] When the adjustment system 1 determines that the variation threshold value is less than the variation threshold value (step S6: Yes), it ends the adjustment of the first sensor terminal 2 (step S7) and ends a series of processes.

[0097] Note that the flowchart shown in FIG. 3 is only an example, and the order of processing may be appropriately changed, or processing may be appropriately added or deleted.

[0098] (4) Variation The following are the modification examples of Embodiment 1.

[0099] Functions equivalent to those of the adjustment system 1 according to Embodiment 1 may be embodied by an adjustment method, a (computer) program, a non-transitory recording medium recording the program, or the like.

[0100] The execution entity of the adjustment system 1 or the adjustment method in the present disclosure includes a computer system. The computer system mainly includes a processor and a memory as hardware. By the processor executing the program recorded in the memory of the computer system, the function as the execution entity of the adjustment system 1 or the adjustment method in the present disclosure is realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, or may be provided by being recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive readable by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). Here, the integrated circuits such as the IC or LSI have different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, for an FPGA (Field-Programmable Gate Array) programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit section inside the LSI, it can also be adopted as a processor. The plurality of electronic circuits may be integrated on one chip, or may be provided dispersedly on a plurality of chips. The plurality of chips may be integrated in one device, or may be provided dispersedly in a plurality of devices. The computer system here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0101] Also, it is not an essential configuration of the adjustment system 1 that a plurality of functions in the adjustment system 1 are integrated in one housing, and the components of the adjustment system 1 may be provided dispersedly in a plurality of housings. Further, at least some functions of the adjustment system 1, for example, some functions of the operation terminal 5 may be realized by a cloud (cloud computing) or the like.

[0102] In Embodiment 1, at least some functions of the adjustment system 1 that are dispersed in a plurality of devices may be integrated in one housing. For example, some functions of the adjustment system 1 that are dispersed in the second sensor terminal 3 and the operation terminal 5 may be integrated in one housing.

[0103] In Embodiment 1, the case where the processing unit 24 of the first sensor terminal 2 executes the determination step of the adjustment method is illustrated. However, for example, the processing unit 52 of the operation terminal 5 may execute the determination step. When the processing unit 52 of the operation terminal 5 executes the determination step, in the communication step, the measurement value in the first measurement step is transmitted from the first sensor terminal 2 to the operation terminal 5, and the measurement value in the second measurement step is transmitted from the second sensor terminal 3 to the operation terminal 5. Thereby, the processing load of the first sensor terminal 2 can be reduced, and for example, the size of the first sensor terminal 2 can be reduced. Note that the processing unit 34 of the second sensor terminal 3 may execute the determination step. When a processing unit other than the processing unit 24 of the first sensor terminal 2 executes the determination step, each information necessary for the execution of the determination step may be acquired by the processing unit that executes the determination step through appropriate communication between the terminals.

[0104] In Embodiment 1, the case where the processing unit 24 of the first sensor terminal 2 executes the timing determination step, movement determination step, and variation amount determination step was exemplified. However, a processing unit other than the processing unit 24 of the first sensor terminal 2 may execute the timing determination step, movement determination step, and variation amount determination step. When a processing unit other than the processing unit 24 of the first sensor terminal 2 executes each step, each information necessary for the execution of each step may be acquired by the processing unit that executes each step through appropriate communication between the terminals.

[0105] In the selection step, the second sensor terminal 3 corresponding to the radio wave whose received radio wave intensity is equal to or greater than the intensity threshold may be selected, and the first sensor terminal 2 may be associated with the selected second sensor terminal 3.

[0106] The predetermined trigger may be that information indicating that the adjustment of the first sensor terminal 2 has not been performed is stored in the storage unit 23.

[0107] Also, in the movement determination step, when the received radio wave intensity measured in the radio wave measurement step is less than the intensity threshold, it may be determined that the second sensor terminal 3 has moved.

[0108] In Embodiment 1, the illuminance information is information for controlling the brightness of the illumination light of the lighting fixture 4 so that the illuminance on the irradiation surface 91, which is, for example, the tabletop, becomes the target value. However, the illuminance information may be information for controlling the brightness of the illumination light of the lighting fixture 4 so that the illuminance on the irradiation surface becomes the target value when, for example, the floor surface 102 is used as the irradiation surface. In this case, the second sensor terminal 3 used in the adjustment method is arranged in advance on the floor surface 102, for example, during a time period outside at night such as during the day.

[0109] In Embodiment 1, the predetermined timing in the timing determination step was exemplified as being at night, for example, but the predetermined timing is not limited to night. For example, at least one of the measured value of the incident light amount measured by the first sensor terminal 2 and the measured value of the illuminance on the irradiation surface 91 measured by the second sensor terminal 3 in a state where the lighting fixture 4 is turned off may be used as the predetermined timing when it is less than the brightness threshold value.

[0110] (Embodiment 2) The adjustment system 1A of Embodiment 2 will be described with reference to FIG. 4.

[0111] As shown in FIG. 4, the adjustment system 1A of Embodiment 2 is different from the adjustment system 1 of the embodiment in that it includes a gateway 6 instead of the operation terminal 5.

[0112] The gateway 6 is a device for connecting the adjustment system 1A to a network such as the Internet. The gateway 6 includes a communication unit 61.

[0113] The communication unit 61 includes a communication interface capable of communicating with the first sensor terminal 2. The communication method between the communication unit 61 and the first sensor terminal 2 is, for example, wireless communication using radio waves in accordance with a communication standard such as a specific low-power radio station in the 920 MHz band, Wi-Fi (registered trademark), or Bluetooth (registered trademark). Note that the communication unit 61 may include an interface capable of communicating with the second sensor terminal 3. In addition, the communication unit 61 includes a communication interface capable of communicating with the server 7 via the network.

[0114] The communication unit 61 of Embodiment 2 receives a trigger signal from the server 7 and transmits the received trigger signal to the first sensor terminal 2. When the first sensor terminal 2 receives the trigger signal, it executes each process included in the adjustment method such as the determination step. That is, in the adjustment system 1A of Embodiment 2, the server 7 transmits a trigger signal to the adjustment system 1A, and the adjustment method is executed in the adjustment system 1A.

[0115] The server 7 is installed in a facility separate from the facility 100 such as the management company 200. The management company 200 is a company that provides a lighting system such as the adjustment system 1A, for example.

[0116] The server 7 includes a communication unit 71 and a processing unit 72.

[0117] The communication unit 71 includes a communication interface capable of communicating with the gateway 6 of the adjustment system 1A via a network.

[0118] The processing unit 72 is mainly composed of, for example, a computer system having one or more processors and one or more memories. In the first sensor terminal 2, the functions of the processing unit 72 are realized by one or more processors executing programs recorded in the memory. The program may be pre-recorded in the memory, may be provided through a telecommunication line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.

[0119] The processing unit 72 performs various processes such as control of the communication unit 71.

[0120] According to the adjustment system 1A of Embodiment 2, it is possible to remotely cause the adjustment system 1A to execute an adjustment process from a facility outside the facility 100 where the adjustment system 1A is installed. Thereby, the number of workers who work at night can be reduced.

[0121] Note that the processing unit 72 of the server 7 may execute a determination step, a timing determination step, a movement determination step, and a variation amount determination step. Each information necessary for the execution of each step may be acquired by the processing unit 72 through appropriate communication via the gateway 6 between the server 7 and each terminal of the adjustment system 1A.

[0122] (Summary) As is apparent from the above-described specific embodiments and modifications, the adjustment method according to the first aspect is an adjustment method of the first sensor terminal (2) executed by a computer system. The adjustment method includes a first measurement step, a second measurement step, a communication step, and a determination step. In the first measurement step, the first sensor terminal (2) disposed on the construction surface (101) where the lighting fixture (4) is installed measures the amount of incident light on the first sensor terminal (2) with the lighting fixture (4) lit. In the second measurement step, the second sensor terminal (3) disposed on the irradiation surface (91) irradiated with the illumination light from the lighting fixture (4) measures the illuminance of the illumination light. In the communication step, the measurement value in the second measurement step is transmitted from the second sensor terminal (3) to the first sensor terminal (2). In the determination step, a correction coefficient for controlling the brightness of the illumination light of the lighting fixture (4) is determined based on the measurement value in the first measurement step and the measurement value in the second measurement step. In the adjustment method, the first measurement step, the second measurement step, the communication step, and the determination step are automatically executed based on a predetermined trigger.

[0123] According to this aspect, the burden on the operator can be reduced.

[0124] The adjustment method according to the second aspect is an adjustment method for the first sensor terminal (2) executed by a computer system. The adjustment method includes a first measurement step, a second measurement step, a communication step, and a determination step. In the first measurement step, the first sensor terminal (2) arranged on the construction surface (101) where the lighting fixture (4) is installed measures the amount of incident light on the first sensor terminal (2) with the lighting fixture (4) lit. In the second measurement step, the second sensor terminal (3) arranged on the irradiation surface (91) irradiated with the illumination light from the lighting fixture (4) measures the illuminance of the illumination light. In the communication step, the measurement value in the first measurement step is transmitted from the first sensor terminal (2) to the operation terminal (5) for adjusting the first sensor terminal (2), and the measurement value in the second measurement step is transmitted from the second sensor terminal (3) to the operation terminal (5). In the determination step, a correction coefficient for controlling the brightness of the illumination light of the lighting fixture (4) is determined based on the measurement value in the first measurement step and the measurement value in the second measurement step. In the adjustment method, the first measurement step, the second measurement step, the communication step, and the determination step are automatically executed based on a predetermined trigger.

[0125] According to this aspect, the burden on the operator can be reduced.

[0126] In the adjustment method according to the third aspect, in the first or second aspect, in the communication step, information on the measurement value in the second measurement step is periodically transmitted from the second sensor terminal (3).

[0127] According to this aspect, the burden on the operator can be further reduced.

[0128] In the adjustment method according to the fourth aspect, in the first aspect, the determination step is executed by the first sensor terminal (2).

[0129] In the adjustment method according to the fifth aspect, in the second aspect, the determination step is executed by the operation terminal (5).

[0130] According to this aspect, for example, the processing load on the first sensor terminal (2) can be reduced, and for example, the size of the first sensor terminal (2) can be reduced.

[0131] In the adjustment method according to the sixth aspect, in any one of the first to fifth aspects, there are a plurality of lighting fixtures (4) and a plurality of second sensor terminals (3). The first sensor terminal (2) is associated with one or more lighting fixtures (4) included in the plurality of lighting fixtures (4). Each of the plurality of second sensor terminals (3) is disposed on any one of a plurality of irradiation surfaces (91) irradiated with illumination light from the plurality of lighting fixtures (4). The adjustment method further includes a radio wave measurement step and a selection step. In the radio wave measurement step, the first sensor terminal (2) receives a plurality of radio waves from the plurality of second sensor terminals (3) and measures a plurality of received radio wave intensities that correspond one-to-one to the plurality of radio waves. In the selection step, the second sensor terminal (3) corresponding to the strongest received radio wave intensity among the plurality of received radio wave intensities is selected, and the selected second sensor terminal (3) is associated with the first sensor terminal (2). In the determination step, a correction coefficient is determined based on the measurement value in the first measurement step and the measurement value measured by the second sensor terminal (3) associated with the first sensor terminal (2) in the selection step.

[0132] According to this aspect, the burden on the operator can be further reduced.

[0133] The adjustment method according to the seventh aspect further includes a timing determination step in any one of the first to sixth aspects. In the timing determination step, it is determined whether it is a predetermined timing. In the adjustment method, when it is determined in the timing determination step that it is a predetermined timing, the first measurement step, the second measurement step, the communication step, and the determination step are executed.

[0134] According to this aspect, for example, the adjustment of the first sensor terminal (2) can be performed at a predetermined timing such as at night.

[0135] In the adjustment method according to the eighth aspect, in the seventh aspect, in the timing determination step, when the current time is nighttime, it is determined that it is a predetermined timing.

[0136] According to this aspect, adjustment of the first sensor terminal (2) can be performed at night or the like.

[0137] The adjustment method according to the ninth aspect further includes a movement determination step in any one of the first to eighth aspects. In the movement determination step, it is determined whether the second sensor terminal (3) has moved during the execution of the adjustment method. In the adjustment method, when it is determined in the movement determination step that the second sensor terminal (3) has moved, the first measurement step, the second measurement step, the communication step, and the determination step are executed again.

[0138] According to this aspect, it is possible to reduce the possibility that a situation occurs in which an inappropriate correction coefficient is determined.

[0139] The adjustment method according to the tenth aspect further includes a radio wave measurement step in the ninth aspect. In the radio wave measurement step, the first sensor terminal (2) receives radio waves from the second sensor terminal (3) and measures the received radio wave intensity. In the movement determination step, when the received radio wave intensity is less than the intensity threshold value, it is determined that the second sensor terminal (3) has moved.

[0140] According to this aspect, it is possible to determine whether the second sensor terminal (3) has moved based on the received radio wave intensity.

[0141] In the adjustment method according to the eleventh aspect, in the ninth aspect, the second sensor terminal (3) includes an acceleration sensor (33). The acceleration sensor (33) detects the acceleration of the second sensor terminal (3). In the movement determination step, when the acceleration detected by the acceleration sensor (33) is equal to or greater than the acceleration threshold value, it is determined that the second sensor terminal (3) has moved.

[0142] According to this aspect, it is possible to more reliably determine whether the second sensor terminal (3) has moved.

In the variation amount determination step, it is determined whether the variation amount of at least one of the measurement value in the 1st measurement step and the measurement value in the 2nd measurement step is equal to or greater than the variation amount threshold value. In the adjustment method, when it is determined in the variation amount determination step that the variation amount is equal to or greater than the variation amount threshold value, the 1st measurement step, the 2nd measurement step, the communication step, and the determination step are executed again.

[0144] According to this aspect, it is possible to reduce the possibility that a situation occurs in which an inappropriate correction coefficient is determined.

[0145] Regarding the configuration other than the 1st aspect, it is not an essential configuration for the adjustment method and can be omitted as appropriate.

[0146] The program according to the 13th aspect is a program for causing a computer system to execute the adjustment method according to any one of the 1st to 12th aspects.

[0147] According to this aspect, it is possible to reduce the burden on the operator.

[0148] The adjustment system (1) according to the 14th aspect includes a first sensor (22), a second sensor (32), a communication unit (31), and a processing unit (24; 34; 52).
