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

Embodiment Construction

[0052] A block diagram of the circuit structure of an urban LED advertising control system figure 2 shown. It consists of a zone controller and multiple billboard controllers. The area controller is composed of a signal sending terminal A, a signal receiving terminal B, a 4G wireless router 2 , a keyboard display module 10 and a microcontroller module 1 . The billboard controller is composed of a signal sending end A, a signal receiving end B, an LED billboard 7 and a microcontroller module 1 . The area controller communicates with the billboard controller through the power line. The terminal is the computer management system located on the top layer, which is composed of 4G wireless router, microcontroller module and computer.

[0053] The hardware structures of the power line communication signal sending end A, signal receiving end B, micro-controller module 1 and power supply module 4 in the area controller and billboard controller are the same.

[0054] The signal sen...

Abstract

The invention relates to a control system for an urban LED advertisement. One advertisement company maintains a large number of advertisement devices in a city, and the presentation effect of the advertisement contents of each LED advertisement board is controlled by one advertisement board controller, and a plurality of advertisement board controllers in one region are provided with one regionalcontroller. The advertisement board controllers communicate with the regional controller through a power line. The regional controller is connected to a mobile wireless communication network Internetthrough a 4G wireless router, so a manager can know and control the operation of the LED advertisement boards of each region at any place through a cellphone APP, a computer and handheld mobile equipment.

Description

(1) Technical field: [0001] The invention relates to an urban LED advertising control system, which includes a zone controller and various billboard controllers, and uses a power line communication method to send a wide pulse signal to a specific point where the cycle voltage of the grid passes through 0 to generate a sudden change current, which is used as a bit value of the signal , the area controller receives the data collected by each billboard 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 through carrier wave. However, the distribution transform...
