Japanese Unexamined Patent Publication No. 2014-89924

Each individual device constituting the lighting control system is given a unique address (hereinafter referred to as a unique ID) such as a 10-digit Mac address. In terms of operation of the lighting control system, it is preferable to use an ID (hereinafter, arbitrary ID) that is simpler than the unique ID and reflects the layout of the actual individual device, rather than using a complicated unique ID.

Therefore, the work of setting an arbitrary ID in the individual device is performed by using the setting device. In this work, the worker collects unique IDs from individual devices by wireless communication, specifies (associates) the installation location of the individual devices corresponding to the unique IDs, and sets an arbitrary ID for the specified individual devices. However, the installation location of the individual device corresponding to the collected unique ID must be specified from among the hundreds of individual devices installed discontinuously. Therefore, it takes time to specify the installation location of the individual device corresponding to the collected unique ID, and the operator has to look up at the ceiling for a long time, which causes fatigue. In the case of a large floor, for example, 700 to 1000 lighting fixtures can be installed, so it is necessary to improve workability.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a control method of a lighting control system that can easily set an arbitrary ID that is short and easy to understand for an individual device. ..

The control method of the lighting control system according to the present invention is a first step of transmitting radio waves to a plurality of individual devices and requesting a unique ID, and setting the unique ID and the received signal intensity of the radio waves from the individual devices as a setter. The unique ID and the received signal strength of the individual device that outputs the received signal strength within a specific range among the plurality of individual devices are displayed on the display unit by the second step of outputting and the operation of the setting device. By operating the setting device and the third step to be displayed, it is an arbitrary ID having a smaller number of digits than the unique ID for the individual device displayed on the display unit in the third step. The fourth step in which the arbitrary ID is set and the received signal strength within a specific range among the plurality of individual devices are output by the operation of the setting device, which is executed after the fourth step. The fifth step of displaying the unique ID and the received signal strength of the individual device on the display unit, and the operation of the setting device on the individual device displayed on the display unit in the fifth step. On the other hand, a sixth step in which an arbitrary ID which is an arbitrary ID having a smaller number of digits than the unique ID is set is provided, and the specific range in the fifth step is a specific range in the third step. With the unique ID of the individual device that is broader and is displayed in the third step and is smaller than the received signal strength issued by the individual device and is not displayed in the third step. The received signal strength is displayed on the display unit in the fifth step.

According to the present invention, the work of setting an arbitrary ID can be simplified by using the received signal strength measured by the individual device when the radio wave is emitted to the individual device for setting the arbitrary ID.

Embodiment 1.
FIG. 1 is a block diagram of the lighting control system according to the first embodiment. The lighting control system includes a setter 10, a controller 12 (denoted as a lighting controller in the figure), a plurality of lighting fixtures 14, an image sensor 16, and a wall switch 18. The setting device 10 is used by the operator for various settings. The setting device 10 performs infrared wireless communication with the controller 12. The controller 12 uses radio waves in the 920 MHz band to communicate with a plurality of lighting fixtures 14, an image sensor 16, and a wall switch 18. The plurality of lighting fixtures 14, the image sensor 16, and the wall switch 18 constitute a plurality of individual devices having a wireless communication function.

FIG. 2 is a diagram showing the configuration of the controller 12. The central arithmetic unit of the controller 12 performs various operations necessary for control. FIG. 3 is a diagram showing the configuration of the lighting fixture 14. The LED light source unit is controlled by the LED control unit. FIG. 4 is a diagram showing the configuration of the image sensor 16. The image sensor 16 includes a solar cell 16A that generates electricity by the irradiation light of a lighting fixture. FIG. 5 is a diagram showing the configuration of the wall switch 18. The wall switch 18 includes a solar cell 18A that generates electricity by the irradiation light of a lighting fixture. Since the image sensor 16 and the wall switch 18 use solar cells 16A and 18A, wireless communication is possible without the need for a power line. In this way, all individual devices are configured to be able to communicate wirelessly.

FIG. 6 is a diagram showing a layout of a controller 12, a lighting fixture 14, an image sensor 16, and a wall switch 18 on an actual floor or the like. Due to the control by the controller 12, the plurality of lighting fixtures 14 are divided into a plurality of groups. One group consists of a luminaire 14 surrounded by one solid square line. Specifically, the first to ninth groups G1, G2, G3, G4, G5, G6, G7, G8, and G9 are defined. The plurality of lighting fixtures 14 in the group are collectively controlled by the controller 12 in the same group.

Arbitrary IDs (1, 2) set in each controller 12 are displayed on the right side of the two controllers 12. Arbitrary IDs (110, 111, 112, 113, 114, 115, 116, 117) set in each image sensor 16 are displayed on the right side of the eight image sensors 16. The number displayed in the luminaire 14 indicates an arbitrary ID set in each luminaire 14. On the right side of the three wall switches 18, the number of buttons (4 for 4L and 1 for 1L) and arbitrary IDs (100, 101, 102) set for each wall switch 18 are displayed.

A method of setting an arbitrary ID by the lighting control system according to the first embodiment will be described with reference to the flowchart of FIG. 7. First, an "ID request" is performed by the setting device 10 (step 30). Specifically, the setting device 10 requests the controller 12 to have unique IDs of a plurality of individual devices. In response to this, the controller 12 emits radio waves to a plurality of individual devices and requests the plurality of individual devices to return a unique ID. This request is broadcast to multiple individual devices.

The radio wave transmitted from the controller 12 is a radio wave in the 920 MHz band. The reason for using the radio wave in the 920 MHz band is to prevent interference with the radio wave in the 2.4 GHz band used in the wireless LAN and Bluetooth (registered trademark), and to secure the range of the radio wave to some extent.

FIG. 8 is a diagram showing frame formats transmitted and received between a setting device, a controller, and individual devices. An "ID request" is a frame having a data length of 2 bytes. The command name of the ID request is "02h", and this command requests an ID response from the individual device. The ID request includes "registration status / model" as DATA1. The "registration status" is 0 or 1, where 0 means requesting an ID response from an individual device whose arbitrary ID is not registered, and 1 requests an ID response from an individual device whose arbitrary ID is registered. That means. The "registration status" of the ID request transmitted here is 0. "Model" is type information indicating the type of individual device. The value of "model" is one of 1, 2, 3, and 4, where 1 refers to a lighting fixture, 2 indicates a motion sensor, 3 indicates an illuminance sensor, and 4 indicates a wall switch. The "model" of the ID request transmitted here is 1. Therefore, the "ID request" transmitted here requests an ID response from the lighting fixture in which the arbitrary ID is not registered.

The circular broken line in FIG. 6 indicates the reach of the radio wave transmitted from the controller 12. When a radio wave of 920 MHz is used, the radio wave can be delivered to a region having a radius of about 30 m, depending on the radio wave condition. Individual devices belonging to the first to fourth groups G1, G2, G3, and G4 are provided within a range in which they can receive this radio wave.

The individual device (lighting fixture 14) that receives the radio wave measures the RSSI (Received Signal Strength Indication) of the radio wave. The received signal strength of the individual device near the controller 12 which is the radio wave transmission source is high, and the received signal strength of the individual device far from the controller 12 is low.

FIG. 9 is a diagram showing the relationship between the distance from the controller 12 and the received signal strength. The individual device near the controller 12 shows a relatively large received signal strength of -10 dB to -20 dB, but the received signal strength of the individual device far from the controller 12 is a low value of about -100 dB, which is the limit of the reception sensitivity. Is shown.

Then, the individual device issues an "ID response" (step 32). As an ID response, the plurality of individual devices return the unique ID, the received signal strength of the radio wave, and the type information to the setting device 10 via the controller 12. One individual device makes one ID response. FIG. 8 shows the frame format of the ID response. An "ID response" is a frame having a data length of 6 bytes. The command name of the ID response is "81h", and this command causes an ID response from the individual device to the controller 12. The ID response includes a "unique ID" as DATA1-3. Further, since the ID request was issued to the "lighting fixture in which the arbitrary ID is not registered", the "registration status" of DATA4 of the ID response is 0 (individual device in which the arbitrary ID is not registered), and the "model". Is 1 (lighting equipment). From the information (type information) of this model, the worker can specify the type of the individual device.

DATA5 includes the correspondence between the RSSI value (received signal strength) and the address (unique ID). The contents of the ID response (unique ID, registration status, model, RSSI (received signal strength)) are all registered in the setting device 10. For example, when an ID response is received from 100 lighting fixtures 14, the contents of the ID response of the 100 lighting fixtures 14 are registered. The controller 12 that has received the ID response may sort a plurality of individual devices in descending order of the RSSI value according to the notified unique ID and RSSI value.

By the way, since the ID response is performed by a plurality of individual devices, there is a possibility that radio waves may interfere with each other. In order to avoid this, each individual device adjusts the response timing according to its own unique ID. Specifically, when the plurality of individual devices make an ID response, the unique ID and the received signal strength are returned after the waiting time corresponding to the unique ID has elapsed. For example, an individual device determines a transmission waiting time based on a random number generated from its own unique ID number, and transmits an ID response after the waiting time has elapsed. FIG. 10 is a diagram showing a frame transmission interval. As shown in FIG. 10, by shifting the timing at which each individual device issues an ID response, it is possible to prevent the ID responses from colliding. Here, the controller 12 is requested by simultaneous broadcasting to return a unique ID to a plurality of individual devices.

Next, the operator narrows the RSSI level with the setting device 10 at hand (step 34). The RSSI level 60 is the received signal strength displayed in decibels. FIG. 11 is a diagram showing a display unit of the setting device. This display unit (display screen) displays the unique IDs and RSSI values (received signal strength) of a plurality of individual devices. When the operator narrows the RSSI level 60, the unique ID of the individual device having a high received signal strength can be displayed on the display unit, and when the RSSI level 60 is widened, the unique ID of the individual device having a low received signal strength can also be displayed on the display unit. It can be displayed. The worker first specifies a relatively narrow RSSI level 60.

Next, the operator presses the "ID read" button on the display unit (step 36). Then, as shown in FIG. 11, the unique ID of the individual device having a relatively high received signal strength and the RSSI of the individual device are displayed. In FIG. 11, the unique IDs and RSSIs of the three individual devices are displayed.

Next, the operator selects one of the unique IDs displayed on the display unit and presses the "ID confirmation" button (step 38). Then, an "ID confirmation command" is issued, and the lighting fixture 14 corresponding to the selected unique ID blinks (in the case of the image sensor 16 or the wall switch 18, the LED attached to them blinks). Blinking is realized by repeating turning on and off 100% from a dark state of the room. In this way, when one of the unique IDs displayed on the display unit is selected, the selected individual device blinks.

FIG. 8 shows the frame format for ID confirmation. "ID confirmation" is a frame having a data length of 4 bytes. The command name for ID confirmation is "02h", and the LED of the individual device having the unique ID specified by DATA1-3 blinks by this command (step 40).

When the individual device that has received the ID confirmation is the image sensor 16, for example, the LED red of the image sensor 16 is blinked for 3 seconds. When the individual device that has received the ID confirmation is the wall switch 18, for example, the LED red and green of the wall switch 18 are blinked alternately for 3 seconds. When the individual device that has received the ID confirmation is the luminaire 14, for example, the luminaire 14 is turned on 100% and turned off three times. The individual device that has received the ID confirmation may perform an operation of notifying the operator that the individual device has received the ID confirmation, and the operation is not limited to blinking.

Next, the operator sets a short ID (arbitrary ID) for the individual device in which the LED is blinked (step 42). Specifically, the operator inputs an arbitrary ID into the setting device 10 and presses the "address setting" button, so that the arbitrary ID is registered. The number displayed in the "address" column in FIG. 11 is an arbitrary ID. The optional ID is preferably a short number that reflects the actual layout of the blinking individual device while referring to the design drawing or the like.

In FIG. 8, the frame format of the “address setting” is described. The “address setting” is a frame having a data length of 6 bytes. The command name for address setting is "12h", and an arbitrary ID is registered in the individual device by this command. The address setting frame includes a unique ID of an individual device for which an arbitrary ID is set as DATA1-3. Further, a model of an individual model for which an arbitrary ID is set as DATA4 is specified. Then, DATA 5 includes an arbitrary ID input by the operator to the setting device 10. As described above, the setting device 10 is configured so that an arbitrary ID (address), which is an arbitrary ID having a smaller number of digits than the unique ID, can be set in a plurality of individual devices. Then, the individual device for which the registration of the arbitrary ID has been completed is not displayed on the display screen of the setting device 10.

Next, the operator confirms whether or not the arbitrary ID has been set for all the individual devices displayed on the display unit of the setting device 10 (step 44). If there is an individual device for which the arbitrary ID has not been set, the process returns to step 38 to set the arbitrary ID.

On the other hand, when the arbitrary IDs have been set for all the individual devices displayed on the display unit, it is confirmed whether the current RSSI level is the widest (step 46). If the current RSSI level set by the setting device 10 is not the widest, the process returns to step 34 to increase the RSSI level. After that, when the ID is read in step 36, the arbitrary ID is not set, and the unique ID of the individual device whose received signal strength is smaller than that of the individual device initially displayed on the display unit is displayed on the display unit of the setting device 10. Is displayed. Arbitrary IDs are also set for the individual devices displayed here in the above-mentioned procedure.

Step 46 is reached again, and the RSSI level is widened again in step 34. In this way, by gradually widening the RSSI level, the RSSI of the individual device displayed on the display unit of the setting device 10 can be narrowed down to some extent, so that the operator presses "ID confirmation". It is possible to roughly predict which individual device will blink at times. Therefore, workability can be improved. Therefore, it is preferable to gradually widen the RSSI level in sequence, instead of widening the RSSI level in the second RSSI level setting (step 34).

By performing step 34 a plurality of times and gradually increasing the RSSI level, the operator first sets an arbitrary ID for the individual device near the controller 12, and then immediately outside the individual device for which the arbitrary ID is set. It is possible to set an arbitrary ID of the individual device in. That is, when the "ID confirmation" is pressed, the worker does not have to walk around in the wide floor to search for the blinking individual device, and the moving distance of the worker can be shortened.

By setting the arbitrary ID with the widest RSSI level, the setting of the arbitrary ID for all the individual devices can be completed. As described above, the setting device 10 has a function of returning a specific received signal strength among a plurality of individual devices and displaying only the individual device for which an arbitrary ID has not been set on the display unit, thereby being efficiently arbitrary. ID can be set.

FIG. 12 is a diagram showing a communication sequence when an arbitrary ID is set for a plurality of lighting fixtures. FIG. 12 shows that there is an ID response from a plurality of luminaires 14 by one ID request. The "group setting" shown in FIG. 12 is for setting a group of the lighting fixture 14. When controlling a plurality of lighting fixtures 14 with one controller 12, such group setting is required.

FIG. 13 is a diagram showing a communication sequence when a person is detected by an image sensor (human feeling, illuminance sensor). Before detecting a person, an arbitrary ID and a group are set by the above-mentioned method. The motion sensor notifies the controller 12 when its own sensor state changes. The dimming rate of the lighting fixture 14 when the presence of a person is not detected is, for example, about 10%. The state of the illuminance sensor is collected at a cycle determined by the controller 12. When the controller 12 detects the presence of a person, the dimming rate of the lighting fixture 14 is set to about 70% in order to achieve the target illuminance of 700 lux.

FIG. 14 is a diagram showing a display unit of a setting device when setting an arbitrary ID and a group in the image sensor. The display unit on the left side is a screen when an arbitrary ID (address) is set, and the display unit on the right side is a screen when a group is set. For individual devices that have received signal strength close to the limit of reception sensitivity (for example, −100 dB), an error can be displayed on the display unit to indicate to the operator that the communication state is poor.

FIG. 15 is a diagram showing a communication sequence of a wall switch in which an arbitrary ID is set. FIG. 15 shows that the brightness of the luminaire 14 is adjusted by pressing the wall switch 18. FIG. 16 is a front view of the wall switch. The wall switch 18 includes an operation button 18a. When the operation button 18a is operated, the bit of the operated button number is turned ON, and the corresponding bit is turned ON / OFF. The controller 12 executes the dimming command of the group corresponding to the operated operation button 18a. The dimming command value is determined by the sampling value of the illuminance sensor. The dimming command value is obtained from the Δ dimming rate corresponding to the Δ illuminance. The luminaire 14 changes the Δ dimming rate according to the set fade value. The Δilluminance and the Δdimming rate are obtained in 1% units based on the illuminance value at the time of 100% lighting. For example, if the illuminance value at 100% lighting is 1000 lux, 1% of the illuminance value is 10 lux. When the target illuminance is 700 lux and the current illuminance is 650 lux, the illuminance difference Δ illuminance is 700-650 = 50 lux, and the dimming rate difference Δ dimming rate is 50 lux / 10 lux = 5%. be. Therefore, when the current dimming rate is 55%, the control dimming rate is 55% + 5% = 60%.

The wall switch 18 includes LED red 18b and LED green 18c. Then, when the ID is confirmed during the arbitrary ID setting work, the LED red 18b and the LED green 18c blink alternately.

In the lighting control system according to the first embodiment, a plurality of individual devices and a controller 12 wirelessly communicate with each other in both directions, and an arbitrary ID is set by using RSSI measured by the individual devices. Various modifications are possible within the range that does not deviate from this feature. For example, as a plurality of individual devices controlled by the controller 12, the lighting fixture 14, the image sensor 16, and the wall switch 18 are mentioned, but other individual devices may be provided. Further, when the worker does not need the model information (type information) of the individual device, the type information may not be included in the ID response.

During the work of setting the arbitrary ID, it was decided not to display the individual device for which the arbitrary ID has been set on the display unit of the setting device 10, but the unique IDs of all the individual devices are displayed on the display unit and the received signal strength (RSSI) is displayed. These may be arranged in descending order of, and arbitrary IDs may be set in sequence.

By adjusting the intensity and frequency of the radio wave transmitted by the controller 12 to a plurality of individual devices at the time of ID request, the range of the radio wave is adjusted, and the number of individual devices returning an ID response is increased or decreased. be able to. Therefore, the frequency used is not limited to the 920 MHz band.

FIG. 17 is a diagram showing a modified example of the lighting control system. The lighting control system of the present invention can be provided as part of a system controlled by a monitoring device and building equipment (BAS). FIG. 18 is a diagram showing a communication sequence of the lighting control system of FIG. Various modifications are possible for the configuration of the lighting control system. For example, as shown in FIG. 19, one controller 12 may control 127 lighting fixtures 14.

If the lighting fixture 14 cannot be provided with a transmission / reception unit for an infrared remote controller due to the design, it is preferable to provide a DIP switch so that an arbitrary ID can be set by the DIP switch. If the position of the DIP switch is 00h by default, the arbitrary ID has not been set, so the arbitrary ID is set by the above method. On the other hand, if the position of the DIP switch is other than 00h, it is assumed that the arbitrary ID has been registered. In this case, the luminaire responds to the ID request from the controller by adding an arbitrary ID to the model and the registered state (registered).

The hardware configuration of the lighting control system is not particularly limited, but an example is shown below. As hardware, each individual device has a receiving device that receives a radio signal (radio wave of ID request, etc.), a transmitting device that transmits a radio signal, a memory, and a processing circuit (CPU,) that executes a program stored in the memory. It is equipped with a processor such as a system LSI). When the individual device receives the ID request, it returns the unique ID stored in the memory and the RSSI value measured by the RSSI measuring unit provided in the receiving device and stored in the memory as an ID response. In the first embodiment, the setting device 10 and the controller 12 for controlling the individual device are separately configured, and when the setting device 10 requests the controller 12 for the unique ID of the individual device, the controller 12 emits a radio wave to the individual device. The individual device is configured to return the unique ID and the received signal strength of the radio wave to the setting device 10 via the controller 12 as an ID response, but the equivalent setting is directly applied to the individual device from the setting device 10 without going through the controller 12. It may be configured to do so. Specifically, the setting device 10 is provided with a control unit for controlling the individual device as the controller 12 has, and when the setting device 10 requests the unique ID of the individual device, the setting device 10 emits a radio wave to the individual device and the individual device. Returns the unique ID and the received signal strength of the radio wave to the setting device 10 as an ID response, and the setting device 10 may be configured so that an arbitrary ID having a smaller number of digits than the unique ID can be set in the individual device. The same effect as that of the first form can be obtained.

These modifications can be appropriately applied to the lighting control system according to the following embodiments. The lighting control system according to the following embodiment will be described focusing on the differences from the first embodiment.

Embodiment 2.
In the second embodiment, a method of setting an arbitrary ID for a plurality of wall switches will be mainly described. FIG. 20 is a diagram showing a communication sequence of arbitrary ID setting according to the second embodiment. The ID request when setting an arbitrary ID to the wall switch 18 is issued by the operator pressing the button of the wall switch 18. For example, when an operator presses and holds the button of the wall switch 18 for 2 seconds, an ID request is issued to the wall switch 18. It is preferable that the wall switch 18 that has received the ID request blinks the LED to indicate that the ID request has been received.

Then, in response to any one of the plurality of wall switches 18 being pressed, the pressed wall switch 18 returns the unique ID to the setting device 10 via the controller 12. After that, the operator sets an arbitrary ID, which is an ID having a smaller number of digits than the unique ID, in the wall switch 18 that has returned the unique ID by the setting device 10. At this time, the group may be set. After setting the arbitrary ID, the LED of the wall switch 18 may stop blinking to indicate that the arbitrary ID has been set.

As described above, for the wall switch 18, the operator sets an arbitrary ID one by one without using the received signal strength (RSSI). For the lighting fixture 14 and the image sensor 16, an arbitrary ID is set by the method described in the first embodiment.

FIG. 21 is a diagram showing a display unit of a setting device when setting an arbitrary ID and a group of a wall switch using the received signal strength (RSSI). An arbitrary ID of the wall switch 18 can be set using the received signal strength shown in FIG. 21, but in that case, a step of searching for the blinking wall switch 18 by the operator is required. However, according to the second embodiment, since the ID request is issued by the worker pressing the wall switch 18 for which the arbitrary ID is to be set, the step of the worker searching for the wall switch 18 is not necessary. Therefore, the work of setting an arbitrary ID can be simplified.
