Introduce you to the development background of smart city street lamp control system

1 Development status of street lighting urban road lighting is an important public facility in people's daily life. There are 100million street lights in China, accounting for 30% of the lighting power consumption and 10% of the total power consumption in China, which is equivalent to the annual power generation of one Three Gorges hydropower station, Clamps with more than large (e.g. plastic film, fiber, etc.) samples. The annual power generation of Jiaya Bay nuclear power plant is 7 times, and about 35% of the electric energy is wasted. Energy conservation and emission reduction has become an important goal in economic construction. With the progress of science and technology, energy-saving lamps and control methods are constantly developing. Since the "ten cities, ten thousand lamps" and 193 "smart cities" Since the pilot promotion, the street lamp control system with wireless technology as the core has great development potential. Good corrosion resistance and casting processability

2 Development stage of street lamp control system

street lamp control system is mainly composed of lamps and control system. In addition to using energy-saving lamps, a unified and efficient control system plays a vital role in the energy conservation and management of street lamps. The control mode of street lamps is constantly developing and evolving, mainly including the following development stages:

stage I: manual control

that is, the most original method to realize switching operation by manually closing/disconnecting the power supply

phase II: clock control

the lights are switched on and off at fixed time through the clock module. However, the lighting strategy is inconvenient to modify and has poor flexibility

phase III: photosensitive control

the light can be switched on and off by sensing the change of light through the photosensitive probe. This method can be operated automatically, but the stability is not enough due to the influence of objective conditions

the fourth stage of the customer's request for the company to provide authoritative test reports: the area control

system adopts GPRS communication technology, which can remotely control each transformer area and a single line. Combined with clock control and longitude and latitude control, it can realize regional control manually or automatically according to the lighting requirements of environmental changes and special events

phase V: single lamp control

on the basis that the metal veneer can further enhance the regional control of its flame retardant performance, the wireless IOT technologies such as ZigBee and GPRS can be used to sense the electrical parameters of any street lamp, and any street lamp can be switched, dimmed and queried
