And the lighting system regulation and control scheme comprises the step of configuring the power-on and power-off state of the lighting devices of each area in the low energy consumption state and the power of the lighting devices in the power-on state in the lighting system regulation and control script. Specifically, the control of the lighting system can be realized in a manner that all lighting loops are controlled in a centralized manner and the control switches are controlled in place through the accurate power utilization regulating and controlling terminal.

For example, if the control scheme 1 relates to a heat dissipation device, the control scheme 2 relates to a production device, and the control scheme 3 relates to a lighting device, the level of the control scheme 2 is higher than that of the control scheme 1, the level of the control scheme 1 is higher than that of the control scheme 3, so that the power consumption threshold 2 of the control scheme 2 is greater than the power consumption threshold 1 of the control scheme 1 is greater than the power consumption threshold 3 of the control scheme 3, and when the control target power consumption reaches the threshold 1, a combination of the control scheme 1 and the control scheme 3 can be screened out.
If the regulation and control parameters uploaded by the peripheral terminal, the electric equipment information managed by the peripheral terminal is acquired, and then the regulation and control scheme containing the electric equipment is screened out to serve as a target regulation and control scheme.
