How Do IoT Cards Apply To Smart Street Lights?
Jul 21, 2018

With the development of the Internet of Things era, IoT cards are used in all walks of life, and the demand for intelligent streetlights is growing. Today, Xiaobian will explain to you how the IoT cards are used in smart street lights.

Challenges in the field of intelligent street lamps

The problem faced by intelligent street lamps is still very large. In the construction aspect, it is necessary to consider how to build a street lamp platform. It is also very important in terms of energy consumption. It is necessary to consider how to reduce the energy consumption of street lamps. Another point is how to maintain intelligent street lamps. One thing is how to manage street lights. Nowadays, the access and operation of street lamps is difficult, the security is poor, the attack is easy, and the construction cost is high.

Intelligent street light solution

For the solution to the problems faced by intelligent street lamps, technical improvements must be made to the light source, remote control and troubleshooting of street lamps should be used, and intelligent street lamps should be remotely controlled based on NB-IoT/eMTC. The intelligent street light scheme can realize the functions of the streetlight “five remote”, including the NB-IoT/eMTC module, the control module, the power supply module and the energy metering module. The power supply module supplies power to the LED lamp through AC power. The NB-IoT communication module can communicate with the server, control and adjust the street lamp through the control module, and report data and information. At the same time, the energy metering module can calculate the amount of light for a single street lamp.

The intelligent street light scheme based on NB-IoT/eMTC has the following advantages:

1. Convenient network: agree to connect to the public network;

2. Standard formation: 3GPP standards, unified industry chain;

3. Safe and reliable: carrier-grade protection, communication success rate is 99%;

4. Single lamp positioning: natural single lamp positioning, remote automatic control;

5. Preventive maintenance: big data type, operation and maintenance costs reduced by 50%.

Based on the above schemes, the functions currently implemented in practical applications are:

1. The street lamp power is divided into time periods. For example, after 6 pm, the day is darker, there are more people on the road, the street lamp is 100% brighter; the night car is less, 50% brightness; after midnight, the road is almost unmanned, 50% Brightness, interval lighting;

2. Automatic adjustment of intelligent algorithm combined with latitude and longitude and sunshine time;

3. Regularly test and report street lights to reduce maintenance costs.
