Applications

32. Advanced solution architecture

33. Advanced solution: Make it work in 4 steps !!

34. #1 Make your lights wireless
• Interface WiART to existing
streetlights to make them
wireless.
• WiART is a low power radio
frequency module which supports
two way wireless communication.
• Supports relay ON / OFF and 0-10
V analog output for dimming.
• All wireless lights form a mesh
network and support hopping of
data and larger area coverage.

35. #2 Form a wireless network
• Automatic wireless mesh network formation.
• Typical range between two lights: approx 50 meters.
• WiART mesh network supports hopping of data and hence very
larger area coverage in tens of kilometers.
• Automatic network – self forming, self healing, self discovery!

36. #3 Connect it to Internet
• Add data concentrator unit (DCU) in the network.
• DCU has a front end of WiART and backend of GPRS and Ethernet.
• DCU acts as two way communication gateway between every light
and Internet based cloud server application.
• DCU supports override switch for controlling the lights in case of
emergency.

37. #4 Remote monitoring and control
• User touch points are added – Internet / mobile / smart phone /
tablet .
• Cloud based server application helps you monitor and control lights.
o ON / OFF / dimming control via time based schedule.
o Configure – site / user.
o Report for audit, consumption.
o Notification / alarm / fault alerts.
Wireless street light connected to cloud and mobile throughDCU

39. • Wireless solution – No hassle of wiring!
• Retrofit, can be integrated with a wide range of
streetlights.
• Single data concentrator unit supports 300 street lights.
• The wireless network is self forming, self healing, self
discoverable and supports 25 hops – completely
automatic.
• Fault detection and notification over email.
• Optional metering for street light electricity consumption.
• Optional motion sensor / light sensor input supported for
localized control.
Highlights

41. Use case #1: GreenLightt for tunnel lighting
• WiART enable lighting nodes with ON / OFF / dimming control.
• Motion sensors are interfaced to detect the location of vehicles.
• Predefined logic to control the intensity of light (dimming / ON / OFF) based on the
vehicle location sensed by motion sensor and to ensure optimized visibility to the
driver.
• Other lights which are not in use are dimmed or switched OFF.
• Completely wireless retrofit solution.. No wires!
• Example:
• When vehicle reaches entry point of tunnel, light ahead are wireless updated to
glow at predefined intensity.

42. Upto 65 % Energy Savings – Intelligent Dimming – Cloud Interface – Easy Installation

48. Use case #2: GreenLightt for petrol pump station
• The fuel pump station lighting solution consists of WiART enable lighting nodes
with ON / OFF control and dimming.
• Motion sensors are interfaced to detect the location of vehicles, such as at ENRTY
and EXIT points.
• Predefined logic to control the intensity of light (dimming / ON / OFF) based on
the vehicle location sensed by motion sensor and to ensure optimized visibility to
the driver.
• Other lights which are not in use are dimmed or switched OFF.
• Example:
• When vehicle motion when sensed at entry of petrol pump station pre
configured lights shall switch ON other lights shall be in dimming mode /
switch OFF.
• When the vehicle leaves the station, motion is detected by the motion sensor
at exit of petrol pump station. Lights shall switch OFF after a predefined time
of interval.

51. Frequently asked questions
FAQ

52. Q & A
Q. Does the solution work with existing lights?
A. Yes. WiART-LC enabled automatic street lighting solution is a retrofit
solution and can work with existing lighting panels and fixtures of all
types.
Q. Our roads are not straight, will WiART still work?
A. Yes. WiART series of modules are based on low power radio
frequency with 360 degree wireless connectivity. It is able to
communicate across obstacles, large angles and curves.
Q. Is it possible to turn off lights manually?
A. Yes. The solution supports manual override feature and no
modification is required in existing wiring.

53. Q. How can we change the ON / OFF schedule?
A. ON / OFF schedule can be changed through the below user touch
points: SMS through registered mobile, smart phone application, cloud
based application.
Q. How do I control dimming?
A. WiART supports 0-10 V analog / PWM output for dimming of the
lighting fixture. Also, occupancy sensor based diming logic can be
implemented for controlling lighting fixture.
Q. Do I need continuous Internet access every day to turn lights ON /
OFF?
A. No. A fixed schedule once updated on the server shall be stored on
the DCU and shall work without connectivity.
Q & A

54. Q. Do I need one SIM card per lighting panel / light pole?
A. No. The solution is based on low power radio frequency and one SIM
card shall be required every cluster of lighting panels / light poles.
Q. Is the solution weather proof / tamper proof?
A. Yes. WiART modules come with required provision and installation
guidelines to avoid tampering and protection from weather.
Q. Would we get an alert if a light is not working?
A. Yes. WiART-LC modules have inbuilt mechanism to detect if the light
is not working. A fault detection alert with location shall be delivered.
