System for controlling decorative lights of buildings of city along both coasts of river

Abstract

The invention relates to a system for controlling the decorative lights of buildings of a city along both coasts of a river. The light controllers for the decorative lights of high-rise buildings of the city along both coasts of the river, LED advertisement boards at the roofs of the buildings, the lights of scenic spots and bridge lights communicated with a regional controller through a power line, and the selection of light modes of the light controller is controlled, thereby enabling the decorative lights of the city along both coasts of the river to present the grand and ordered beautifulscenes. The regional controller is connected to a mobile wireless communication network through a 4G wireless router, so a manager can know and control the operation of the lights of each region through a cellphone APP, a computer and handheld mobile equipment.

Description

(1) Technical field: [0001] The invention relates to a lighting control system for buildings on both sides of the city along the river, which includes a regional controller and various lighting controllers, and uses a power line communication method to send a wide pulse signal to a specific point where the cycle voltage of the power grid passes through 0 to generate a sudden change current, which is used as the position of the signal. The regional controller receives the data collected by each lighting controller, and accesses the 4G mobile wireless communication network through a wireless router, so that no matter where you are, you can use mobile phones, computers and handheld mobile devices to achieve wireless networking. (two) background technology: [0002] Current power line communication mainly refers to power line carrier communication and two-way power frequency communication. Power line carrier communication PLC uses the existing power line to transmit signals thro...

Problems solved by technology

[0004] The detection of TW A CS signals is mainly based on time-domain difference technology. Most of these methods have complex data processing, poor real-time performance, and high equipment costs. In order to determine whether the signal bit is "1" or "0", due to the rigor of the calculation, the interference signal will seriously affect the judgment result of the detected signal, so the original method is difficult to apply in our country
