Application of LED display screen in intelligent bus stop sign

The meaning of intelligent bus stop sign

The intelligent bus stop is part of the intelligent bus system and there is currently no very precise and official definition. We simply understand it as a bus stop with intelligent control system and advanced technology information display, real-time report bus operation to meet and facilitate passenger needs.

The modern city bus electronic stop sign system is the newly developed intelligent electronic stop sign product. This bus intelligent electronic stop sign is the use of bus car GPS global positioning system, through the bus information management center server group and wireless data transmission network. , receive and release bus operation information. The background not only integrates the GPS monitoring and dispatching system, but also has three mainstream systems: video surveillance system and public information distribution system. During the waiting process, the public can know the location of the bus to be used in advance through the LED bulletin screen of the electronic stop sign. It may take several stops and how far to reach the station. At the same time, the intelligent electronic stop sign can also play weather information and travel reference. Waiting for service information; watching the news, entertainment programs, advertising and other videos in real time through the LCD screen of the electronic stop sign, truly realizing the realm of travel and waiting for the car is not boring.

At present, a small part of the country is actively carrying out trial work on smart bus stop signs. For example, the intelligent bus electronic stop sign project in Jiangsu Province was launched in Zhangjiagang, which opened up a new mode of promoting public transport informationization, marking the new breakthrough in the application of Internet of Things in the “smart city”. Zhangjiagang intelligent bus electronic stop sign system uses global satellite positioning technology (GPS), geographic information system technology (GIS-T), video codec technology and intelligent sensing technology (active RFID) to integrate organically through stable communication methods. New generation application system. The system makes full use of the current public transport vehicle GPS data of Zhangjiagang Public Transport Intelligent Dispatching Management System, establishes a bus arrival station forecasting system through technical docking, dynamically displays all bus line arrival information that stops at the station, and provides real-time and accurate vehicles to the waiting passengers. Station forecast. In addition, the system also comes with multimedia video playback, real-time video surveillance, passenger waiting feedback, public information release, blind assisted tour, coupon issue service and other functions. The Beijing Traffic Operation Monitoring and Dispatching Center also said that the intelligent transportation service project will be launched next year, including various forms of “bus-to-station forecasting”, such as electronic stop signs, website announcements, and mobile terminals, which will strive to be realized next year. When passengers are waiting, just look down at the phone and you will know that the next bus will arrive in a few minutes. In addition, the release of subway congestion and free parking spaces during the peak period will enable mobile phones to publish information. Up to now, Tangshan City has installed 92 intelligent electronic station signs on several key sections and has been put into operation. There are currently 1,496 buses in Shenyang to achieve related functions, and all buses are expected to be realized by the end of the year. Fuzhou has also started the project of intelligent public transport management system. It is expected that the Fuzhou public transport intelligent management system will be completed by the end of 2012 to realize real-time monitoring and dispatching of the city's buses, and electronic bus stop signs will also appear on the streets.
