JP 2014-89924 A

  A unique address (hereinafter referred to as a unique ID) such as a 10-digit Mac address is assigned to each individual device constituting the lighting control system. In the operation of the lighting control system, it is preferable to use an ID (hereinafter, an 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.

  Then, the operation | work which sets arbitrary ID to an individual apparatus is performed using a setting device. In this work, a worker collects a unique ID from an individual device by wireless communication, specifies (associates) the installation location of the individual device corresponding to the unique ID, and sets an arbitrary ID to the specified individual device. However, the installation locations of the individual devices corresponding to the collected unique IDs must be identified from among the individual devices installed in a discontinuous manner. Therefore, it takes time to specify the installation location of the individual device corresponding to the collected unique ID, and the worker has to look up at the ceiling for a long time, thus causing fatigue. In the case of a large floor, for example, as many as 700 to 1000 lighting fixtures are attached, so that workability must be improved.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an illumination control system that can simplify the task of setting a short and easy-to-understand arbitrary ID for individual devices.

  An illumination control system according to the invention of the present application includes a setting device, a plurality of individual devices, and a controller that controls the plurality of individual devices, and the controller sets unique IDs of the plurality of individual devices from the setting device. When requested, the controller emits radio waves to the plurality of individual devices, and the plurality of individual devices return the unique ID and the received signal strength of the radio waves to the setting device via the controller as an ID response, and The setting device is configured to be able to set an arbitrary ID, which is an arbitrary ID having a number of digits smaller than the unique ID, to the plurality of individual devices.

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

Embodiment 1 FIG.
FIG. 1 is a block diagram of a lighting control system according to the first embodiment. The lighting control system includes a setting device 10, a controller 12 (described as a lighting controller in the drawing), 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 communicates with the plurality of lighting fixtures 14, the image sensor 16, and the wall switch 18 using radio waves in the 920 MHz band. 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 illustrating a configuration of the controller 12. In the central processing unit of the controller 12, various calculations necessary for control are performed. FIG. 3 is a diagram illustrating a configuration of the lighting fixture 14. The LED light source unit is controlled by the LED control unit. FIG. 4 is a diagram illustrating a configuration of the image sensor 16. The image sensor 16 includes a solar cell 16 </ b> A that generates electric power using irradiation light from a lighting fixture. FIG. 5 is a diagram showing the configuration of the wall switch 18. The wall switch 18 includes a solar cell 18 </ b> A that generates electric power by irradiating light from a lighting fixture. Since the image sensor 16 and the wall switch 18 use the solar cells 16A and 18A, wireless communication is possible without requiring a power line. In this way, all the individual devices are configured to be able to communicate wirelessly.

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

  Arbitrary IDs (1, 2) set for 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 for each image sensor 16 are displayed on the right side of the eight image sensors 16. The numbers displayed in the lighting fixtures 14 indicate arbitrary IDs set for the respective lighting fixtures 14. On the right side of the three wall switches 18, the number of buttons (four for 4L and one for 1L) and arbitrary IDs (100, 101, 102) set for each wall switch 18 are displayed.

  A method for setting an arbitrary ID by the illumination control system according to Embodiment 1 will be described with reference to the flowchart of FIG. First, an “ID request” is made by the setting device 10 (step 30). Specifically, the setting device 10 requests the controller 12 for unique IDs of a plurality of individual devices. In response to this, the controller 12 sends radio waves to a plurality of individual devices and requests the plurality of individual devices to return unique IDs. This request is sent to a plurality of individual devices by simultaneous broadcasting.

  The radio wave transmitted from the controller 12 is a radio wave in the 920 MHz band. The reason why the 920 MHz band radio wave is used is to prevent interference with the 2.4 GHz band radio wave used in wireless LAN and Bluetooth, and to ensure a certain range of radio wave reach.

  FIG. 8 is a diagram illustrating a frame format transmitted / received between the setting device, the controller, and the individual device. The “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 state / model” as DATA1. “Registered state” is 0 or 1, where 0 means that an ID response is requested to an individual device that has not registered an arbitrary ID, and 1 means that an ID response is requested to an individual device that has an arbitrary ID registered. That means. The “registration state” of the ID request transmitted here is 0. “Model” is type information indicating the type of individual device. The value of “model” is any one of 1, 2, 3, and 4. 1 indicates a lighting fixture, 2 indicates a human sensor, 3 indicates an illuminance sensor, and 4 indicates a wall switch. The “model is” of the ID request transmitted here is 1. Therefore, the “ID request” transmitted here requests an ID response to a lighting fixture whose arbitrary ID is not registered.

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

  The individual device (lighting fixture 14) that has received the radio wave measures RSSI (Received Signal Strength Indication) of the radio wave. The received signal strength of an individual device close to the controller 12 that is a radio wave source is large, and the received signal strength of an individual device that is remote from the controller 12 is small.

  FIG. 9 is a diagram illustrating the relationship between the distance from the controller 12 and the received signal strength. Individual devices near the controller 12 exhibit a relatively large received signal strength of −10 dB to −20 dB, but the received signal strength of the individual devices far from the controller 12 is a low value of about −100 dB, which is the limit of reception sensitivity. Indicates.

  Next, the individual device issues an “ID response” (step 32). 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 as an ID response. One individual device makes one ID response. FIG. 8 shows the frame format of the ID response. The “ID response” is a frame having a data length of 6 bytes. The command name of the ID response is “81h”, and an ID response is sent from the individual device to the controller 12 by this command. The ID response includes “unique ID” as DATA1-3. In addition, since the ID request is issued for “lighting fixtures whose arbitrary ID is not registered”, “registration state” of DATA 4 of the ID response is 0 (individual device whose arbitrary ID is not registered), and “model” Is 1 (lighting fixture). From this model information (type information), the operator can specify the type of the individual device.

  DATA5 includes a correspondence between an RSSI value (received signal strength) and an address (unique ID). The contents of the ID response (unique ID, registration state, 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 100 lighting fixtures 14 are registered. The controller 12 that has received the ID response may sort the plurality of individual devices in descending order of the RSSI value based on 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. In order to avoid this, each individual device adjusts the response timing according to its own unique ID. Specifically, when a plurality of individual devices make an ID response, they return the unique ID and received signal strength after the waiting time corresponding to the unique ID has elapsed. For example, the 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 illustrating a frame transmission interval. As shown in FIG. 10, it is possible to prevent ID responses from colliding by shifting the timing at which each individual device issues an ID response. Here, the controller 12 requests the broadcast ID to return a unique ID to a plurality of individual devices.

  Next, the worker 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 illustrating a display unit of the setting device. This display unit (display screen) displays unique IDs and RSSI values (reception 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 large received signal strength can be displayed on the display unit, and when the worker increases the RSSI level 60, the unique ID of the individual device having a small received signal strength is also displayed on the display unit. Can be displayed. The worker first specifies a relatively narrow RSSI level 60.

  Next, the worker presses an “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 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). If it does so, "ID confirmation command" will come out and the lighting fixture 14 applicable to the selected unique ID will blink (in the case of the image sensor 16 or the wall switch 18, LED attached to them will blink). Blinking is realized by repeating 100% lighting and extinguishing from a dark room. Thus, when one of the unique IDs displayed on the display unit is selected, the selected individual device blinks.

  FIG. 8 shows a 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 blinks for 3 seconds. When the individual device that has received the ID confirmation is the wall switch 18, for example, the red and green LEDs of the wall switch 18 are alternately blinked 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 for notifying the worker that the individual device has received the ID confirmation, and the operation is not limited to blinking.

  Next, the worker sets a short ID (arbitrary ID) for the individual device whose LED is blinked (step 42). Specifically, when the operator inputs an arbitrary ID to the setting device 10 and presses an “address setting” button, the arbitrary ID is registered. The number displayed in the “address” column in FIG. 11 is an arbitrary ID. The arbitrary ID is preferably a short number reflecting the actual layout of the blinking individual device while referring to the design drawing.

  In FIG. 8, the “address setting” frame format of “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 that sets an arbitrary ID as DATA1-3. Also, an individual model for which an arbitrary ID is set as DATA4 is specified. The DATA 5 includes an arbitrary ID input by the operator to the setting device 10. Thus, the setting device 10 is configured to be able to set an arbitrary ID (address), which is an arbitrary ID having a number of digits smaller than the unique ID, to a plurality of individual devices. Then, the individual device whose optional ID has been registered is not displayed on the display screen of the setting device 10.

  Next, the operator confirms whether or not an 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 is not set, the process returns to step 38 to set the arbitrary ID.

  On the other hand, when the arbitrary ID has 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 widen the RSSI level. Thereafter, when ID reading is performed in step 36, an arbitrary ID is not set, and a unique ID of an individual device having a received signal strength 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. For the individual devices displayed here, an arbitrary ID is set in the above-described procedure.

  Step 46 is reached again, and the RSSI level is increased again at step 34. In this way, by gradually increasing the RSSI level little by little, the RSSI of the individual device displayed on the display unit of the setting device 10 can be narrowed down to some extent, so the operator has pressed “ID confirmation” It is generally possible to predict which individual devices will sometimes flash. Therefore, workability can be improved. Therefore, it is preferable to gradually increase the RSSI level little by little, instead of making the RSSI level the widest in the second RSSI level setting (step 34).

  By performing step 34 a plurality of times and gradually increasing the RSSI level little by little, the worker first sets an arbitrary ID for the individual device close to 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 an individual device in That is, when “ID confirmation” is pressed, the operator does not have to walk around a wide floor and search for a blinking individual device, and the movement distance of the operator can be shortened.

  By setting the arbitrary ID with the RSSI level being widest, 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 devices for which the arbitrary ID is not set on the display unit. An ID can be set.

  FIG. 12 is a diagram illustrating 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 lighting fixtures 14 by a single ID request. “Group setting” shown in FIG. 12 is for performing group setting of the lighting fixture 14. Such group setting is necessary when a plurality of lighting fixtures 14 are controlled by a single controller 12.

  FIG. 13 is a diagram illustrating a communication sequence in human detection by an image sensor (human feeling, illuminance sensor). Prior to human detection, an arbitrary ID and a group are set by the method described above. The human sensor notifies the controller 12 when its own sensor state changes. The dimming rate of the luminaire 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 period 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 illustrating a display unit of a setting device when an arbitrary ID and a group are set in the image sensor. The left display section is a screen when an arbitrary ID (address) is set, and the right display section is a screen when a group is set. In addition, about the individual apparatus which gave the received signal strength close | similar to the limit (for example, -100dB) of receiving sensitivity, an error display can be carried out on a display part and it can also show an operator that a communication state is bad.

  FIG. 15 is a diagram illustrating a communication sequence of a wall switch in which an arbitrary ID is set. FIG. 15 shows that the brightness of the lighting fixture 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 a dimming command for the group corresponding to the operated operation button 18a. The dimming command value is determined by the sampling value of the illuminance sensor. A dimming command value is obtained from a Δ dimming rate corresponding to Δ illuminance. The luminaire 14 changes the Δ dimming rate according to the set fade value. The Δ illuminance and the Δ dimming rate are obtained in units of 1% based on the illuminance value at the time of 100% lighting. For example, if the illuminance value at 100% lighting is 1000 lux, 1% 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 ratio difference Δ dimming rate is 50 lux / 10 lux = 5%. is there. 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. When the ID confirmation is received during the arbitrary ID setting operation, the LED red 18b and the LED green 18c blink alternately.

  In the lighting control system according to Embodiment 1, a plurality of individual devices and the controller 12 perform wireless communication in both directions, and an arbitrary ID is set using RSSI measured by the individual devices. Various modifications are possible without departing from this characteristic. For example, although the lighting fixture 14, the image sensor 16, and the wall switch 18 were mentioned as a several separate apparatus controlled by the controller 12, you may provide another separate apparatus. Further, when the worker does not need the information (type information) of the model of the individual device, the type information may not be included in the ID response.

  During the operation of setting the arbitrary ID, the individual device for which the arbitrary ID has been set is not displayed on the display unit of the setting device 10, but the unique ID of all the individual devices is displayed on the display unit, and the received signal strength (RSSI) These may be arranged in descending order, and an arbitrary ID may be set sequentially.

  When an ID request is made, the controller 12 adjusts the intensity and frequency of radio waves transmitted to a plurality of individual devices, thereby adjusting the range of the radio waves and increasing or decreasing the number of individual devices that return an ID response. be able to. Therefore, the use frequency is not limited to the 920 MHz band.

  FIG. 17 is a diagram illustrating a modification of the illumination control system. The lighting control system of the present invention can be provided as part of a system that receives control of a monitoring device and a building facility (BAS). FIG. 18 is a diagram showing a communication sequence of the illumination control system of FIG. Various modifications can be made to the configuration of the illumination control system. For example, as shown in FIG. 19, 127 lighting devices 14 may be controlled by one controller 12.

  When it is not possible to provide the illuminating device 14 with a transmission / reception unit for an infrared remote controller, 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 is not 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, the arbitrary ID is registered. In this case, the luminaire responds to the ID request from the controller with an arbitrary ID added 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. Each individual device has, as hardware, a receiving device that receives a radio signal (such as an ID request radio wave), a transmitting device that transmits a radio signal, a memory, and a processing circuit (CPU, CPU) that executes a program stored in the memory. A processor such as a system LSI). When the individual device receives the ID request, the individual device 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 that controls the individual device are configured separately. When the setting device 10 requests the controller 12 for a unique ID of the individual device, the controller 12 emits radio waves to the individual device, The individual device is configured to return the unique ID and the received signal strength of the radio wave as an ID response to the setting device 10 via the controller 12. However, the setting equivalent to the individual device is directly set from the setting device 10 without using the controller 12. It may be configured to do. Specifically, the setting device 10 is provided with a control unit that controls an individual device that the controller 12 has, and when the setting device 10 requests a unique ID of the individual device, the setting device 10 emits a radio wave to the individual device. May return 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 number of digits smaller than the unique ID can be set for each individual device. An effect equivalent to that of Embodiment 1 can be obtained.

  These modifications can be applied as appropriate to the illumination control systems according to the following embodiments. Note that the illumination control system according to the following embodiment will be described with a focus on differences from the first embodiment.

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

  Then, when one of the plurality of wall switches 18 is pressed, the pressed wall switch 18 returns a unique ID to the setting device 10 via the controller 12. Thereafter, the operator uses the setting device 10 to set an arbitrary ID, which is an ID having a smaller number of digits than the unique ID, on the wall switch 18 that has returned the unique ID. At this time, a group may be set. In addition, after setting arbitrary ID, it is good to show that blink of LED of the wall switch 18 is complete | finished and arbitrary ID was set.

  Thus, for the wall switch 18, the operator sets an arbitrary ID one by one without using the received signal strength (RSSI). About the lighting fixture 14 and the image sensor 16, arbitrary ID is set by the method demonstrated in Embodiment 1. FIG.

  FIG. 21 is a diagram illustrating a display unit of a setting unit when setting an arbitrary ID and group of a wall switch using 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 wall switch 18 blinking by the operator is required. However, according to the second embodiment, since the ID request is issued when the worker presses the wall switch 18 for which an arbitrary ID is desired to be set, the worker does not need to search for the wall switch 18. Therefore, the task of setting an arbitrary ID can be simplified.
