The intelligent bus electronic stop sign is a core component of the smart bus system and is the information control center of the smart station. The electronic station sign shall realize the release of public travel service information to the electronic stop sign through the travel information service system, and realize the status monitoring and remote maintenance management of the electronic stop sign to support the intelligent construction of the bus.
The intelligent bus electronic stop sign system consists of two parts: the front-end intelligent bus electronic station hardware terminal and the back-end bus intelligent equipment monitoring and maintenance integrated management platform.
The front-end intelligent bus electronic station hardware terminal includes a cabinet shell, an LCD liquid crystal display, an industrial grade 4G LTE router, a centralized controller, a multimedia controller, a temperature-controlled heat sink unit, a full-state detecting unit, a fault alarm unit, and a TTS voice broadcast unit. Advertising light box unit.
The integrated management platform for back-end bus intelligent equipment monitoring and maintenance includes functional modules such as comprehensive display, equipment monitoring, material management, information release, statistical query, system configuration, and network security defense.
