Description

A street lamp narrow-band Internet of Things control system and usage method

technical field

The invention belongs to the field of street lamp control, and in particular relates to a street lamp narrow-band Internet of Things control system and a use method.

Background technique

With the gradual increase of social energy consumption, the energy crisis is becoming more and more serious. Under the current social background, strengthening the application of the concept of energy saving has become an inevitable trend of social development. In energy consumption, electric energy consumption accounts for a large part. Urban lighting system is an important part of municipal engineering construction. The scope of urban lighting system continues to expand, resulting in more and more serious energy consumption problems. Strengthening the energy-saving design of urban lighting systems in the new era is an urgent problem to be solved. The lighting fixtures used in the traditional lighting system have high energy consumption. LED street lamp is an energy-saving product. Through the transformation of LED street lamps on the traditional urban lighting system, energy saving can be achieved. However, at present, most cities, especially small and medium-sized cities, do not have a high level of automated management of street lighting systems. Although the "full night lighting constant illumination" lighting method can meet the needs of night lighting, it has caused a great waste of power resources.

The function of street lights is to provide sufficient light for pedestrians and vehicles when the light intensity is insufficient. The current street light control system mostly adopts the control method of manual timing switch, that is, the street lights are fully on during a certain period of time, such as between 6:00 pm and 6:00 am, and the street lights are all off at other times, which is obviously unreasonable. . When the weather suddenly encounters bad weather and needs street lamps to supplement lighting, the above-mentioned control method cannot meet the requirements of the system. Therefore, the light intensity collected by the illuminance sensor is used to control the on and off of the light, which can significantly reduce power consumption.

At the same time, it can also provide sufficient light according to the time period of pedestrians and traffic. At present, there are many ways to change the lighting: such as using PWM to adjust the brightness of each lamp, which can be used for new street lamp lines, but the high cost is a problem worth considering. Because, when PWM is regulated, the wired network is complicated and expensive; the wireless network is used, and the lines are few, but the general wireless network, the transmission distance is limited; the mobile Internet, such as GPRS/LTE, the hardware cost High, and the monthly rent is also high.

Recently, the narrowband Internet of Things technology has matured, and it has many advantages, such as low cost, low power, simple access, plug and play, easy compatibility with existing terminals, and improved network coverage. It is used for street lighting system dimming , An ideal way to save energy.
