Intelligent Bus Stop Signage: A New Standard
This system fundamentally transforms public transportation by moving beyond static information. It introduces a three-layer IoT architecture (sensing, network, application) to manage the entire process from data collection to real-time display. Key functionalities include real-time operational status monitoring (GPS, speed), dynamic route updates, and user-friendly interfaces with voice announcements, significantly enhancing the travel experience and enabling better operational oversight.
IoT Architecture & Data Flow
The system utilizes STM32 microcontrollers for both bus and bus stop nodes. Bus nodes feature DHT11 sensors for temperature/humidity and a Hezhou Air780EG module for GPS, with Kalman filtering applied for enhanced positioning accuracy. Data is transmitted securely via 4G networks using the MQTT protocol, with AES encryption and QoS mechanisms ensuring reliability. Bus stop nodes display information on Taojingchi X2 LCD screens and use BY9301 voice modules for announcements, all managed by a Node.js backend on Alibaba Cloud.
Enhanced Commuter Experience & Smart City Integration
The system addresses the core pain points of traditional public transport: uncertainty and anxiety. Passengers gain access to real-time bus information via WeChat mini-programs, enabling informed travel decisions and route planning. Voice announcements and comfort evaluations (e.g., in-cabin temperature) further personalize the experience. For operators, the system provides a robust tool for real-time monitoring and optimizing bus routes, contributing significantly to a more efficient and user-centric smart city infrastructure.
