Lighting System Debugging Tool Evaluation - Full Coverage of DALI/DMX/Dimmer/PWM/TRIAC Lighting Protocol

1, Three control methods for intelligent lighting

There are three main technical routes for modern lighting control systems: DALI (Digital addressable lighting interface, IEC 62386Standard) , 0-10V/1-10V Simulate dimming, Modbus RTU Switch/dimming control. modbusDebugging Assistant "provides 5 debugging tools covering these three routes.

Two, DALIDebugging assistant — IEC 62386 Standard protocol

DALI (Digital Addressable Lighting Interface) It is the International Electrotechnical CommissionIEC 62386Standard, Specially designed for lighting control. And withModbusDifferent, DALIYesLayer 2 protocol, Define frame format directly on the physical layer, No additional communication protocol stack is required.

2.1 DALICore concepts of the agreement

• Short address (0-63) : EachDALIEquipment (Ballast/LEDDriver) The unique address, OneDALIMost on the bus64A device
• Group address (0-15) : Equipment can be attributed to16A group, Implement area lighting through multicast control
• Scene (0-15) : Each device can store16The brightness value of a scene, Scene switching only requires one instruction
• radio broadcast: One instruction controls all devices on the bus
• Forward frame (19Position) : controller→Equipment, Contains address bits, command bits, and data bits
• Backward frame (11Position) : Equipment→controller, Used for status inquiry and fault feedback

2.2 DALIDebugging tool functionality

• Device addressing: Support random addressing (Random Address Allocation) ——Bus scanning→Send initialization command→Assign short addresses0-63→Verify address
• Dimming control: 0-254Level brightness adjustment (0=Close, 254=Brightest, 255=maintain) , Support direct arc power control (Direct Arc Power Control)
• Color temperature adjustment: ForDT8Type of equipment (Adjustable color temperatureLEDDriver) , supportTc (Color temperature) Adjustment2700K-6500K
• Scene management: Read/set device storage16The brightness value of a scene, One click scene switching (GO TO SCENECommand)
• Fault diagnosis: Query device status——Lamp malfunction, Ballast malfunction, Power failure, etc, Display Chinese fault description
• Fade in and fade out time: set upFade Time (0=Immediately, 1=0.7s, ……, 15=90s) AndFade Rate (Fade out rate)

Three, DALIGateway debugging tool

DALIGateway is the gatewayDALIBus accessModbus/RS485The internetBridge devices. Through the gateway, ModbusThe main station can controlDALILighting equipment on the bus.

The core functions of gateway debugging tools:

• Gateway status query: Read gateway version, DALIBus power status, Number of online devices
• Virtual address mapping: WillModbusRegister address mapping toDALIShort address/group address/broadcast address, Configure mapping table
• Controlled through gatewayDALIEquipment: send outModbusInstructions→Gateway translation:DALIInstructions→ControlDALIlamps and lanterns
• Gateway scenario configuration: Preset scenarios in the gateway (ModbusTrigger→Gateway executionDALIScene switching)

Four, Dimmer debugging tool

Dimmer debugging tool is designed forACDimming module (Thyristor/TRIACDimming, MOSDimming along the back edge of the tube) AndDC PWMDimming moduleDebugging tools.

4.1 Dimming type support

• Controllable silicon dimming (the front) : Suitable for traditional incandescent lamps and dimmable lampsLEDDrive
• MOSTube dimming (Trailing edge) : Applicable toLEDLamp, No flicker, No noise
• 0-10VSimulate dimming: Standard analog dimming interface
• PWMDimming: Pulse width modulation, Adjustable frequency (100Hz-25kHz)

4.2 Debugging function

• Dimming curve setting: Linear/logarithmic (Human perception) /Custom curve
• Minimum/maximum brightness limit: preventLEDFlashing at extremely low brightness or overheating at extremely high brightness
• Soft start time: The time for the brightness to slowly increase from 0 to the target value when turning on the light
• Gradient switch: Set the transition time for turning on/off lights, Avoid discomfort caused by sudden lighting and extinguishing

Five, Intelligent lighting debugging assistant

General intelligent lighting system debugging tool, supportMulti protocol mixingThe lighting system: Modbus RTU On/off control + 0-10V Dimming + DALI Equipment control. The core functions include:: Multi area lighting management, Schedule control (By week+time period) , Illuminance linkage (Read the illuminance sensor→Automatically turn on the lights below the threshold) , Energy consumption statistics.

Six, 8Road lighting debugging tool

Regarding Route 8ModbusSpecialized debugging tools for lighting controllers: 8Road independent switch+0-100%Dimming+fully open/fully closed+2Road interlock (Dual control at both ends of the corridor) +Scene switching.

Seven, Summary

From international standardsDALITo simplifyModbusRelay lights on, From0-10VSimulate dimming toPWMDigital dimming——5The lighting debugging tool covers the entire protocol stack of lighting control.
