Abstract:
An exemplary street lamp system includes a monitoring center, a first street lamp, a first sensor, a first signal receiving unit, a first signal sending unit, and a first power management unit. The monitoring center is configured for sending a monitoring signal. The first sensor is configured for detecting an operating state of the first street lamp and generating a first detection signal. The first signal receiving unit is configured for receiving the monitoring signal. The first signal sending unit selectively operates in a power-on state where the first signal sending unit sends a feedback signal to the monitoring center based on the monitoring signal, or a power-off state where the first signal sending unit does not send the feedback signal to the monitoring center. The first power management unit is configured for switching the first signal sending unit to the power-off state in response to the first detection signal.
