Description

Smart Street Light

The present invention relates to a smart street lamp, and in particular to a lamp device that can be operated according to the primary side voltage of a switch box device.

At present, the operation mode of the street light installation is to put an earth leakage protection circuit breaker (Earth Leakage Circuit Breaker, ELCB) between the external power supply circuit and the street light, as a protection device for leakage or short circuit. Among them, the junction of ELCB and power supply circuit is called primary side circuit, and the junction of ELCB and street lamp is called secondary side circuit, and is used to output secondary side voltage to drive street lamp to emit light. In terms of maintaining operation, the voltage or current value of the secondary side can be monitored, and the monitoring data of the street light device can be sent back to the management platform through various networks to judge the abnormal state of the street light. However, once a leakage or short circuit occurs, the ELCB will trip the switch to protect the circuit. At this time, the primary side circuit will still maintain the original voltage, but the voltage and current values of the secondary side circuit will return to zero, making the street light The device is not working properly without returning data. In this case, the management platform can only judge that there is no return data from the street lamp device, but cannot judge the cause of the abnormal state, such as abnormal power supply circuit, ELCB tripping, unstable network, or abnormality of the lamp itself. Sending manpower to manually confirm the cause of the abnormal state is very inconvenient and causes additional burden, and it also delays the repair schedule of the street lamp device.
