Description

    FIELD OF THE INVENTION
  • The present invention relates generally to the technical field of building management systems or building automation systems comprising a plurality of building devices, e.g. BACnet devices. In particular the present invention relates to a method for commissioning a DALI network (e.g. DALI bus) for control lighting in a building, the DALI network comprising a DALI application controller, control gears (e.g. lamps, LED, dimmer), and input devices (e.g. light sensors).
    • BACKGROUND
  • Building automation systems are used to control devices in a building such as HVAC equipment, blind actuators, and lighting actuators. Building automation systems provide communication between and control of devices in a building. The DALI standard provides a protocol for digital communication between components of a lighting installation. In installations, a DALI control unit organizes and manages the information flow and the access of all components to the data line. DALI offers functionality that goes beyond the switching and dimming of individual DALI devices. For example, constant light control can be achieved via constant light control circuits can be set up via brightness sensors and complex light scenes can be compiled, stored and recalled.
  • Each DALI system contains at least one Application Controller (Master Device), up to 64 gears (e.g. lamps) and up to 64 input devices (pushbuttons defined in IEC 62386-301, analog input devices defined in IEC 62386-302, or others).
    DALI system commissioning requires two basic steps:
    • 1st step: each physical device needs to get a network address (so called DALI short address).
    • 2nd step: each physical device must be localized and assigned to a logical device of the DALI Application Controller (device engineered in the building plan).
  • IEC 62386-102 defines the address assignment and localization procedures for gears and IEC 62386-103 for input devices.
    For input devices the DALI standard defines a random address allocation procedure and a specific IDENTIFY DEVICE command to trigger a blink or beep function to support the localization of an input device. This way the commissioner can request one after another a device to blink/beep until the wanted device answers and can be assigned. There are several problems with this setup for input devices:
    1. 1. Having to blink or beep every device one by one to find a specific device is very time-consuming and inefficient. Especially for large projects totaling hundreds of input devices.
    2. 2. In many cases using IDENTIFY DEVICE command on every device is error-prone, because multiple pushbuttons or dimming devices can be mounted close together in a wall, so a beep sound from these devices is hard to distinguish. Blinking LEDs are often small and covered by a transparent housing and difficult to see.

    DETAILED DESCRIPTION

    • (ST1) providing a set (e.g. a list) of discovered, unassigned input devices and a set (e.g. separate list) of engineered input devices by the DALI application controller, wherein access to the respective sets is provided by a suitable commissioning tool;
    • (ST2) selecting a DALI input device (ID1 - ID4) from the set of engineered devices displayed by the commissioning tool (CT) by a commissioner (C), wherein this selection is triggering a message from the commissioning tool (CT) to the DALI Application Controller (DAC) which starts monitoring the event messages from not-yet-assigned input devices on the DALI network (DN), wherein the type of input devices corresponds to the type of the input device selected by the commissioner and wherein this selection is starting a timer, which defines the starting point of a defined time period;

    • (ST7) assigning a logical address within the DALI network (DN) to said correct DALI input device (ID1 - ID4) in the DALI application controller. Advantageously the DALI Application Controller provides a list (e.g. a spreadsheet or csv-list) of discovered, unassigned input devices and a list (e.g. a separate list) of engineered input devices. This information is accessible by the commissioning tool. Advantageously the commissioning tool is implemented or realized on a laptop or a tablet computer).
  • The light sensor (LS) of a selected DALI input device (ID1 - ID4) can be activated by suitable light sources (T): torch, point light source, light beam, light ray, Infrared, etc. Advantageously the light source (T) is a point-shaped or beam-shaped light source. Further exemplary light sources (T) are laser pointer, e.g. 5mW laser pointer (green, 532 nm) with 3 mm Beam diameter, or 5mW laser pointer (red, 635 nm) with 3 mm Beam diameter.
  • Advantageously the light sensor (LS) on the selected DALI input device (ID1 - ID4) is activated if exposed to a defined threshold value of luminous intensity (e.g. a defined value of luminance; luminance is candela per square metre (cd/m2)) provided by the light source (T).
  • Advantageously the light sensor (LS) is activated when exposed to a defined sequence of light signals (e.g. light on - light off - light on - light off) provided by the light source (T) within the defined time period.
  • Advantageously the light sensor (LS) is activated when exposed to a significant difference in brightness compared to the current ambient light within the defined time period.

    The received readings of the event messages generated by the sensor must differ significantly one after the other in order to localize the sensor.
  • Small variations in brightness (below the defined threshold value) of the other sensors or non-assignment related activity (e.g. another person turning on a light in a different room) can also trigger event messages, which must be discarded for sensor localization by the DALI application controller.
  • According to an advantageous embodiment, the length of the defined time period is determined by configuring the DALI application controller (DAC) and/or the commissioning tool (CT).

Advantageously activating the light sensor (LS) on the selected DALI input device (ID1 - ID4) by exposing the light sensor (LS) to a light source (T) with a predefined pattern has to be performed before the timer expires.
  • This means feedback must be provided to the selected DALI input device by the commissioning engineer until the defined time period (e.g. 3 seconds or 5 seconds or 10 seconds or 15 seconds or 20 seconds) or a defined time out (e.g. 3 seconds or 5 seconds or 10 seconds or 15 seconds or 20 seconds) expires. The defined time period or the defined time out can be determined or configured by the commissioner with the commissioning tool and/or the DALI application controller.
  • The length or the span of the defined time period has to be chosen so that the commissioner can actually perform the operation "activating the light sensor". This can be done individually by each respective commissioner.
  • If the defined time period is too short and the timer expires before activating the light sensor (LS), the DALI Application Controller can not find the selected input device.
  • According to an advantageous embodiment, the light sensor (LS) on the selected DALI input device (ID1 - ID4) is activated by a guided light beam directed to the light sensor (LS). The guided light beam can be generated or provided by the LED of a smartphone (CT). Advantageously by a white LED of a smartphone.

  • This reliably prevents faulty connections, especially if many devices are set up simultaneously by several commissioning engineers.
  • The proposed workflow provides a significant efficiency advantage compared to IEC 62386-103 workflow, where for every input device up to 64 interactions are required. Shorter commissioning time translates to lower cost of commissioning.
  • The proposed workflow with the visual/auditive feedback of the selected device prevents nearly all types of erroneous assignment. Especially the proposed workflow with the visual/auditive feedback of the selected device and the usage of a pre-defined pattern prevents nearly all types of erroneous assignment. Not having to find and correct such errors further reduces the required commissioning time and cost.

Advantageously the DALI Application Controller provides a list (e.g. a spreadsheet or csv-list) of discovered, unassigned input devices and a list (e.g. a separate list) of engineered input devices. This information is accessible by the commissioning tool.
    DALI is specified by a series of technical standards in IEC 62386. This ensures that equipment from different manufacturers will interoperate in DALI systems (DALI networks) DN.
  • A DALI network DN typically comprises at least one DALI application controller DAC, a network (e.g. bus) power supply, input devices ID1 - ID4 (e.g. sensors and push-buttons), control gear (e.g. LED drivers or dimmers) with DALI interfaces. A DALI application controller DAC can control, configure or query each network device by means of a bi-directional data exchange. The DALI protocol allows addressing the network devices individually, in groups or via broadcast.
  • Each device in a DALI network DN is assigned a unique short address between 0 to 63, making up to 64 control gear devices CG1, CG2 in a basic DALI system. Address assignment to devices in a DALI network DN is accomplished over the bus using a "commissioning" protocol, usually after all hardware of the DALI system (DALI network DN) is installed. In a DALI network DN data is transferred between devices by means of an asynchronous, half-duplex, serial protocol over a two-wire bus with a fixed data transfer rate of 1200 bit/s. A DALI network DN can be arranged in bus or star topology, or a combination of these. Each device on a DALI network DN can be addressed individually.
  • The exemplary illustration according to figure 2 shows lamps CG1, CG2 as exemplary control gears. A DALI network DN can comprise a plurality of control gears (e.g. lamps, LED, dimmer), also control gears of different types.
  • The light sensor LS of a selected DALI input device ID1 - ID4 can be activated by suitable light sources T: torch, point light source, light beam, light ray, Infrared, etc. Advantageously the light source T is a point-shaped or beam-shaped light source.

  • Advantageously the light sensor LS is activated when exposed to a significant difference in brightness compared to the current ambient light within the defined time period.
  • Advantageously by means of the light source T (e.g. a torch or a flashlight, etc.) a significant difference in brightness must be triggered one or more times during the defined time period (time window), e.g. flashing of the flashlight.
    The received readings of the event messages generated by the sensor must differ significantly one after the other in order to localize the sensor.
  • Small variations in brightness (below the defined threshold value) of the other sensors can also trigger event messages, which must be discarded for sensor localization by the DALI application controller DAC.
  • Advantageously the DALI application controller DAC and/or the commissioning tool CT are comprising a timer to provide the defined time period.

  • Advantageously the light sensor LS on the selected DALI input device ID1 - ID4 is configured to be activated by exposing the light sensor LS to the light source T within the defined time period (e.g. 10 seconds, 15 seconds, 20 seconds, 30 seconds) two times.
  • Advantageously the light sensor LS on the selected DALI input device ID1 - ID4 is configured to be activated by exposing the light sensor LS to a light source T exceeding a defined light intensity.
  • Advantageously the set of discovered and unassigned input devices and the set of engineered input devices is updated accordingly. Advantageously the update of the lists is performed automatically if a change of the sets is discovered.
  • According to an advantageous embodiment, an output device (monitor, display) of the commissioning tool CT is presenting a successful assigning of a logical address.
  • According to an advantageous embodiment, providing the set (e.g. a list) of discovered, unassigned input devices and the set (e.g. separate list) of engineered input devices is performed automatically by the DALI application controller DAC. Advantageously the update of the lists is performed automatically if a change of the sets is discovered. Advantageously the DALI application controller DAC is commissioned with a handheld device as a commissioning tool CT (e.g. tablet computer, smartphone, laptop, mobile or desktop computer). Prior to the logical device assignment, advantageously the DALI application controller DAC performs random address allocation as defined in IEC 62386-103 section 9.14.2.
  • The DALI application controller provides a list of discovered, unassigned input devices and a separate list of engineered input devices. This information is accessible by the commissioning tool CT via suitable communication means (e.g. WLAN, radio communication, IP communication).
  • In the arrangement as illustrated in figure 2 the exemplary input device ID3 comprises an exemplary speaker SP for sending an audio signal (e.g. beeping or sounding or buzzing). Optionally the audio signal can also be replaced by a visual signal (e.g. by a flasher or blinker sending unit). Optionally the audio signal and the visual signal can be outputted together (means simultaneously) by the exemplary input device.
  • In the arrangement as illustrated in figure 2 the exemplary input device ID2 comprises an exemplary lamp LED as output-unit to output a visual signal. The output-unit LED to output a visual signal can be a flasher or a blinker sending unit or an indicator light.
  • The exemplary input devices ID1 to ID4 can comprise in each case an exemplary speaker SP and/or an exemplary light-output-unit LED.
  • The arrangement as illustrated in figure 2 is configured to perform a logical assignment of input devices ID1 - ID4 to control gears CG1, CG2 by performing the following workflow of actions (steps, points) 1 to 5:
    1. 1. The commissioner C selects a DALI input device ID4 - ID4 from the list of engineered devices displayed by the commissioning tool CT. This triggers a message from the commissioning tool CT to the DALI Application Controller DAC which starts monitoring the event messages from not-yet-assigned input devices on the DALI bus or DALI network DN.
    2. 2. The commissioner C directs a light source LS (e.g. torch or if close to the sensor the build-in flash of a commissioning tool/mobile phone) in the direction of the light sensor LS (input devices of type IEC 62386-304) and turns the light source LS on and off two times within a defined time period (e.g. 10 seconds). This is reflected in variation of the sensor raw value by minimum of 30% (default value, configurable for instance via the commissioning tool CT) and generates a pattern of event messages on the DALI bus DN. The DALI Application Controller DAC monitors the bus DN and upon pattern detection with e.g. 4 variations of minimum 30% (bright-dark-bright-dark) of the raw value the sensor within 10 seconds is identified.
    3. 3. The DALI Application Controller DAC sends the IDENTIFY DEVICE command to the input device which triggered the event pattern. The addressed input device blinks and/or beeps.
    4. 4. The commissioner C gets the visual and/or audible confirmation that the correct device is selected. This can be confirmed via the commissioning tool CT.
    5. 5. After the confirmation the DALI Application Controller DAC completes the logical assignment. The list of discovered & unassigned input devices and the separate list of engineered input devices is updated accordingly. And the screen (e.g. display) on the commissioning tool CT is updated to indicate the successful assignment. The commissioner C can continue with the logical assignment of the next input device from point 1.
  • DALI Light sensor messages are encoded and scaled according to manufacturer-specific parameters gathered from the device during the logical assignment process, so before the logical assignment is complete only raw sensor data is available and only deviations in % (in percentage range) can be detected. In case of having two light sensors in proximity (for example in the same room), it may happen that a nearby sensor also detects the bright-dark-bright-dark pattern, but its raw value change will be smaller. The commissioner can adjust the minimum change from 30% to a different value. Additionally, the DALI Application Controller upon seeing two patterns within <1 second interval will select the input device reporting larger value variation (the one directly under the light source).
  • For example, bright-dark-bright-dark pattern with minimum 30% raw value variation is very atypical for DALI bus or DALI network DN, so a chance of it randomly appearing in another room is extremely low. Should it still happen, and two input devices report such pattern with more than Is difference the DALI Application Controller DAC will interrupt the logical assignment sequence to prevent erroneous assignment. The handheld device CT (e.g. smartphone or tablet computer) displays an error message, and the commissioner C can restart the logical assignment sequence.
  • The proposed exemplary workflow provides a significant efficiency advantage compared to IEC 62386-103 workflow, where for every input device up to 64 interactions are required. Shorter commissioning time translates to lower cost of Siemens solution. The proposed exemplary workflow with the visual/auditive feedback of the selected device prevents nearly all types of erroneous assignment. Not having to find and correct such errors further reduces the required commissioning time and cost.
  • The binary search workflow for gears CG1, CG2 reduces the assignment speed as well (interacting up to 6 times to assign one of 64 devices instead of iterating up to 64 times). The proposed workflow triggers the IDENTIFY DEVICE command only once removing the risk of errors. Moreover, with a single interaction with the input device, the proposed workflow reduces assignment time even further.
  • The proposed workflow involves for instance two consecutive blinks but does not require specialized hardware (in many cases the build-in camera LED of the commissioning tool is enough). Moreover, the proposed workflow works with generic IEC 62386-304 input devices.
