Streetlights are among a city’s most important assets, providing safer streets,
parks, and city centers. They also consume a huge part of a city’s budget — as
much as 40% in electricity bills and significant resources for maintenance and
operations. Cities today need smarter street lighting systems that can reduce
electricity use, costs, and carbon emissions while enhancing environments.
1.Dispersed and mesh street light pillar
2.Intelligent management of streetlight
3.High labor cost of fail detection and maintenance
Based on the requirements of streetlight intelligent management, we provided
GPRS based solution. SignShine DTU can be connected with controller by RS485,
it has GPRS Simcard inserted which can communicate via mobile wireless network.
These SIM cards could provide special private APN (Private Access Point Network)
service which prevented access from public internet and also enabled the access
from the power company’s data center to a certain remote meter.
Benefits of the solution:
1.Easy to deploy network and all the streetlights covered.
2.Real time data transmission,reduces the response time
3.Point-to-point control optimizes the energetic consumption
Key benefits of SignShine DTU:
1.Industrial design and wide voltage power supply design for harsh environment.
Wide operation temperature: -25~65℃
Power input: 7-32V DC
EMC&EMI test passed
2.OS with MMU(memory management unit)for fast data processing.
3.Support several work mode and protocols, multi trigger ways,customized firmware supported.
