Abstract
A system for controlling LED lightbox power supplies, comprises the lightbox supplies disposed inside a lightbox and correspondingly connected with LED light bars one by one. All the lightbox power supplies are connected in series with one another via a 485 communication bus. Meanwhile, a wireless communication device connected in series with the lightbox power supplies is further mounted inside the lightbox. A gateway device for wirelessly connecting with the wireless communication device and uploading data acquired to a cloud server, is arranged outside the lightbox. A sensor set connected in a wired manner with the wireless communication device is arranged on an outer wall of the lightbox.

A system for controlling LED lightbox power supplies, comprising the lightbox power supplies disposed inside a lightbox and correspondingly connected with LED light bars one by one, wherein, all the lightbox power supplies are connected in series with one another via a 485 communication bus;
- a wireless communication device connected in series with the lightbox power supplies is further mounted inside the lightbox;
- a gateway device for wirelessly connecting with the wireless communication device and uploading data acquired to a cloud server, is arranged outside the lightbox;
- a sensor set connected in a wired manner with the wireless communication device is arranged on an outer wall of the lightbox.
A remote control method of a system for controlling an LED lightbox power supply, comprising the following steps:
- (1) detecting output voltage and output current of a lightbox power supply in real time by a voltage detection circuit and a current detection circuit, and detecting environment information of a lightbox in real time through a sensor set;
- (2) analyzing and determining whether the lightbox power supply malfunctions by a microprocessor according to the output voltage and the output current of the lightbox power supply, and determining whether the lightbox power supply is suitable for continuing work according to the environment information of the lightbox;
- (3) converting a serial port signal of the microprocessor into a 485 communication signal by a conversion circuit, and transmitting the determination result of the microprocessor to a gateway device through a wireless communication device, and updating the determination result to an Internet by the gateway device;
- and
- (4) registering a server on an Internet by an LED lightbox management party to remotely gasp a current state of the lightbox power supply, and deciding whether to turn off the lightbox power supply according to the determination result of the microprocessor, wherein, maintenance personnel are scheduled for overhauling if the lightbox power supply has malfunctioned.
