the method for electrifying the LED driving power supply comprises the following steps:
the mains supply acquisition module generates a power-off signal when the mains supply is powered off and sends the power-off signal to the control part; and the control part controls the bidirectional switching module to be connected with the storage battery after receiving the power-off signal.
6. The LED lamp single lamp control device according to claim 1, further comprising a positioning acquisition processing part in communication connection with the control part; the data storage part also stores lamp position information;
the positioning acquisition processing part acquires the real-time position of the LED lamp to generate real-time position information and generate real-time position information; once the collected real-time position information changes, the positioning collection processing part generates a trigger signal and sends the trigger signal and the real-time position information to the control part, the control part judges whether the real-time position information is consistent with the lamp position information, and when the real-time position information is not consistent with the lamp position information, the control part replaces the lamp position information in the data storage part with the real-time position information and controls the communication part to send the real-time position information to the server.
7. The LED lamp single lamp control device as claimed in claim 1, wherein the communication part is an NB-IOT module.
8. An LED lamp single lamp control method based on the LED lamp single lamp control device of any one of claims 1-7, characterized by comprising the following steps:
the LED lamp single lamp control device is electrified and initialized;
waiting for the server to send a control instruction, wherein the control instruction comprises a timing opening and closing instruction;
judging whether the waiting time is greater than a preset waiting time threshold value or not; when the control instruction is received within the preset waiting time threshold, controlling the LED driving power supply to be electrified according to the timing on-off instruction; and when the waiting time is greater than the preset waiting time threshold, reading the time in the clock module and controlling the LED driving power supply to be electrified according to the time and the timing on-off data.
