Intelligent bus stop display panel

Abstract

The invention discloses an intelligent bus stop display panel, which is characterized in that the GPRS (general packer radio service) communication module and the Bluetooth short-distance communication module of the bus station are connected to a micro controller through serial ports; an LED (light emitted diode) display screen and a temperature and sound sensor module are connected to the micro controller through IO (input output) interfaces; a solar cell panel and a storage battery combined module are connected to the micro controller as well as each module circuit; the Bluetooth module is used for searching for the stop information of bus; the communication between the bus station and the bus station is realized by using the GPRS communication module; the position information of the bus is transferred in real time; the real-time position of the bus in each route is displayed by the LED display screen, thereby informing the passenger waiting at the bus stop display panel of the stop time of the bus; and for the passengers not at the bus stop display panel, the information can be sent to the bus stop display panel in the manner of sending short massage and then the stop time and the real-time position information of each bus under the bus stop display panel are automatically replied through the GPRS, thereby being convenient for distant passengers to make a schedule as early as possible.

Description

technical field [0001] The invention belongs to the technical field of electronic devices, and specifically relates to an intelligent bus display stop sign which can effectively display information of various bus vehicles and surrounding environments, and facilitate passengers to wait for a bus. Background technique [0002] With the development of urban construction, in order to alleviate traffic congestion and facilitate citizens to travel, more and more buses are put into urban public transportation, so the bus stop signs set on both sides of the road to indicate bus route information are becoming more and more popular. more. However, most of the traditional bus stop signs are simple in structure and single in function, and often can only statically display some line information, which cannot solve the problem of passengers predicting the arrival information of vehicles, and cannot solve the problem of passengers obtaining bus lines, time and other information at any time...

AI Technical Summary

Problems solved by technology

However, most of the traditional bus stop signs are simple in structure and single in function, and often can only statically display some line information, which cannot solve the problem of passengers predicting the arrival information of vehicles, and cannot solve the problem of passengers obtaining bus lines, time and other information at any time and place. The problem of relevant information has brought a lot of inconvenience and waste of time to citizens' travel.

The electronic bus stop sign device (CN201359778) invented by Chen Jie proposed a solution for intelligent information display, mainly using GPS plus GPRS, but this method also has shortcomings. GPS satellite positioning must be received by the receiver at the same time. More than one satellite signal can locate the exact location, but in the high-rise buildings in the city, the GPS satellite signal will be greatly weakened, and it is often difficult to receive more than three satellite signals at the same time, which will cause system failure
