Abstract

The invention discloses an intelligent integrated controller based on the OFDM technology. The controller includes an A phase line, a B phase line, a C phase line, and a zero line having three-phase power supply. The A phase line and the zero line are connected to an AC-DC module therebetween. The A phase line, the B phase line, the C phase line and the zero line are in separate connection to a coupling transformer. The coupling transformer and a simulation front-end chip are connected. The simulation front-end chip is connected to a DSP chip through a SPI interface. The DSP chip is connected to a high-end ARM chip through a serial port. The high-end ARM chip is connected to a metering module through a serial port. An MMC interface of the high-end ARM chip is connected to a TF card thereon. The high-end ARM chip is in separate connection to a DDR3 memory and a NAND memory through a data bus. The high-end ARM chip is also in connection to a liquid crystal display contact screen through a video control bus. The high-end ARM chip is in connection to a GPRS module through a serial port. A router interface of the high-end ARM chip is also connected to a wired communication module. According to the invention, the controller has strong processing capability, fast speed and excellent expanding function.

Description

technical field [0001] The invention relates to a control device of a street lamp, in particular to an intelligent centralized controller based on OFDM technology, and belongs to the technical field of the Internet of Things. Background technique [0002] At present, the information system in the field of street lamps is mainly a three-remote system for line management. The centralized controller in the three-remote system mainly realizes the control and acquisition of the loop. The existing centralized controller generally directly outputs the control signal to control the switch of the AC contactor to realize the switch of the loop, and it generally realizes the access to other equipment through the 485 interface. However, with the application of single lamp monitoring, the centralized controller for three remotes cannot meet the application requirements because there is no power carrier module. Moreover, most of the main processing chips of the centralized controller u...
