Solar street lamp-based control system, single-lamp controllers and centralized controller

The invention belongs to the field of street lamp illumination, and relates to a solar street lamp-based control system, single-lamp controllers and a centralized controller. The solar street lamp-based control system comprises a solar panel, a plurality of single-lamp controllers, the centralized controller, a monitoring center and an application terminal, wherein the solar panel supplies electricity to the single-lamp controllers; each single-lamp controller is connected with the centralized controller in a wireless communication manner; the centralized controller is connected with the monitoring center in a GPRS communication manner; and the monitoring center communicates with the application terminal by an Internet. One single-lamp controller is arranged on each lamp post; and each single-lamp controller can communicate with a plurality of electronic ballasts on the lamp post, so that a multi-channel lamp holder power supply on the lamp post is controlled; the on-off and the brightness of each lamp holder on the lamp post are controlled; the state of each lamp holder is monitored; flexible group control is carried out on the lamp holder on the lamp post; and various energy-saving control modes of every second lamp lighting, every third lamp lighting, an extinguishing slow lane lamp holder, brightness lowering at midnight and the like can be achieved.
