Intelligent bus LED guideboard based on wireless network

Abstract

The invention discloses a bus intelligent LED guideboard based on a wireless network, and belongs to the field of bus guideboards. The bus intelligent LED guideboard is characterized in that the bus intelligent LED guideboard comprises a vehicle-mounted intelligent terminal controller, and the vehicle-mounted intelligent terminal controller is connected with an LED display module, a counting module, a communication module and a positioning stop announcement module; the LED display module comprises a front-end LED display screen, a vehicle side LED display screen, a rear-end LED display screenand an in-vehicle LED display screen; the counting module is used for calculating the number of passengers getting on the bus at each station; and the communication system is used for communicating with a background system. The bus intelligent LED guideboard has the advantages that the positioning is more accurate, and the interference is avoided; and the information can be fed back to a background system in real time for timely deploying vehicles, so that the operation is convenient and quick.

Description

technical field [0001] The invention relates to a bus sign, in particular to a wireless network-based smart LED sign for public transport. Background technique [0002] The bus sign is a display board installed on the front of the bus, which is used to remind passengers of the bus number and the name of the station passing by this time, so that passengers can take the bus. The bus sign is also distributed on the side of the bus, the rear end and the inside of the bus. They are called bus side signs, bus rear signs and bus interior signs. At present, most of the bus signs adopt intelligent LED signs, and the LED signs are equipped with vehicle-mounted intelligent terminal controllers. At the same time, the vehicle-mounted intelligent terminal controllers are equipped with GPS positioning devices for bus positioning and station reporting. [0003] At present, most of the bus stop reporting systems configured in smart LED street signs use GPS positioning and station reporting ...

AI Technical Summary

Problems solved by technology

In actual development, the GPS receiver calculates its own position based on the data sent from more than three satellites, and completes the positioning. The basic principle of GPS positioning is to use the instantaneous position of the high-speed moving satellite as the known starting data. The method of intersecting the space distance at the rear determines the position of the point to be measured; the vehicle-mounted intelligent terminal controller is installed on the bus, and its working environment is relatively harsh. It is necessary to manually correct the station announcement information, which increases the workload of the driver, and at the same time, it is easy to cause the passengers to not get off in time, causing inconvenience to the passengers

[0004] In addition, the vehicle-mounted intelligent terminal controllers currently deployed in smart LED road signs are uniformly controlled by the background system, and the background system performs unified deployment of buses during peak traffic periods, but the current deployment is mostly adjusted according to time. Deploy the shuttle bus or the station train at 7 o'clock, and end at 9 o'clock. The actual number of passengers cannot be fed back to the background system in a timely manner through the on-board intelligent terminal controller, for example, in bad weather or in a certain road section. In a large meeting, the number of passengers will increase sharply, and the peak hours will be extended, but this situation cannot be fed back to the background system in real time for timely deployment of vehicles
