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 station intelligent stop sign communication 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 signal sending terminal A, signal receiving terminal B and CC2530 radio frequency communication module 1. The intelligent display stop sign and the vehicle-mounted controller 7 adopt radio frequency communication. 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 an intelligent stop board communication system of a bus station. The bus station is provided with an intelligent display stop board to display bus arrival conditions. Each ofa vehicle-mounted controller of a bus or the intelligent display stop board of the bus station comprises a CC2530 RF communication module, the intelligent display stop board of each bus stop sends detection signal cyclically according to positions of buses, and information exchange is realized when the vehicle-mounted controller of the bus which arrives in the station makes response. A concentrated controller communicates with each intelligent display stop board via a power line, and accesses the mobile radio communication network via a 4G wireless router.

Description

(1) Technical field: [0001] The present invention relates to an intelligent bus stop sign communication system, which includes a centralized controller and various intelligent display stop signs, adopts the power line communication method, and sends a wide pulse signal to a specific point in the grid cycle voltage crossing 0 area 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 ca...
