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

[0054] The block diagram of the circuit structure of a bus arrival intelligent display system is as follows: figure 2 shown. It consists of a centralized controller and multiple intelligent display stop signs. The centralized controller is composed of a signal sending end A, a signal receiving end B, a 4G wireless router 2 , a keyboard display module 10 and a microcontroller module 1 . The intelligent display stop sign is composed of a signal sending terminal A, a signal receiving terminal B and a microcontroller module 1 . The intelligent display stop sign communicates with the vehicle-mounted controller 11 via infrared. The centralized controller communicates with the intelligent display stop sign using 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.

Abstract

The invention relates to a bus arrival intelligent display system. An intelligent display bus stop board is installed at a bus station to display the station arrival conditions of various buses; infrared communication is adopted between buses and the bus station; a centralized controller is arranged in a power transformer area; the centralized controller communicates with the intelligent display bus stop board by using a power line; and the centralized controller accesses a mobile wireless communication network through a 4G wireless router. Passengers can use mobile APPs, computers and handheld mobile devices to check the arrival situations of various buses no matter where the passengers are.

Description

(1) Technical field: [0001] The invention relates to an intelligent bus arrival display system, which includes a centralized controller and various intelligent display stop signs, 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 the position of the signal value, the centralized controller receives the data collected by each intelligent display stop sign, 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 realize 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 wa...
