The intelligent circuit breaker 200 is communicatively connected with the control box 100, and the power supply module 300 is electrically connected to the intelligent circuit breaker 200 and multiple groups of street lamp control circuits; specifically, as Figure 1 and Figure 2 shown, Figure 2"QF1, QF2, QF3" in it are the switch circuit breakers 310 of the power supply module 300, and "ZNC1, ZNC2, ZNC3" represent multiple intelligent circuit breakers 200. This embodiment provides three groups of street lamp control circuits.

[0024] Preferably, the intelligent circuit breaker 200 includes an overcurrent alarm device which is electrically connected to the street lamp control circuit and is used to monitor the current in the street lamp control circuit.
