In some examples, the branch power supply loop may be connected to the external power supply subsystem 200. The external power subsystem 200 may be configured with an external power policy configured with a power time. Every other power supply time, the external power supply subsystem 200 charges each individual storage battery 110. For example, the power supply time may be set to 24 hours. The power supply time can be adjusted according to actual conditions.
In some examples, each of the individual storage batteries 110 may be provided with a first charge amount detection unit 111.

In some examples, the street light 1 control subsystem may be preconfigured with a light supply meter. The light supply table may store light supply conditions and light supply policies corresponding thereto (i.e., corresponding light supply policies). The light supply condition may include an environmental condition and a power condition. The street lamp 1 control subsystem collects environmental information through a pre-configured sensor to generate the environmental condition. The charge condition is generated based on the first charge value and the second charge value. And the street lamp 1 control subsystem determines a light supply strategy from the light supply meter according to the light supply condition and controls the working power of the street lamps 1 of the regional group through the light supply strategy.
In some examples, the street light 1 control subsystem may detect ambient illumination via an illumination sensor. The environmental condition may include the illuminance information. In some examples, the street lamp 1 control subsystem obtains visibility information by connecting with an external weather database. The environmental conditions include the visibility information.

When the average value of the first electric quantity value is within the independent electric quantity threshold range, the corresponding light supply strategy comprises the following steps of calculating the working power of the street lamp through an independent lamp control algorithm: w ═ wx (R-R)/(G-G). W is the working power of each street lamp, W is a preset reference working power, x is a power adjustment factor, R is a preset reference illuminance value, R is an illuminance value detected by an illuminance sensor, G is a preset visibility value, and G is a visibility value obtained through an external weather database.
In some examples, the charge condition may include a sub-controlled charge threshold range. When the second electric quantity value falls into the sub-control electric quantity threshold range, the corresponding light supply strategy comprises configuring a threshold electric quantity threshold, controlling the main storage battery 120 to supply power for the street lamp 1 with the first electric quantity value lower than the threshold electric quantity threshold, and controlling the independent storage battery 110 to supply power for the street lamp 1 with the first electric quantity value higher than the threshold electric quantity threshold.
In some examples, the charge condition includes a first lower charge value and a second lower charge value. When the average value of the first electric quantity value is lower than the first lower limit electric quantity value and the second electric quantity value is lower than the second lower limit electric quantity value, the light supply strategy comprises that less than half of street lamps 1 in the control area group are closed and are not adjacent to each other among the closed street lamps 1.

As described above, the optimal light supply strategy can be determined by screening both the power condition and the environmental condition, so as to ensure the energy consumption and the light quantity.
In another embodiment of the invention, the charge condition comprises an individual charge threshold range. When the average value of the first electric quantity value is within the independent electric quantity threshold range, the corresponding light supply strategy comprises the following steps of calculating the working power of the street lamp through an independent lamp control algorithm:
