China Mobile Smart Toilet

China Mobile's smart toilet adopts an advanced solution provided by Deyi Environment, integrating IoT, AI, and automation control technologies to build a closed-loop architecture of 'perception-cognition-execution', achieving efficient management and service optimization.

1. Technical Architecture and Core Functions

1. Perception Layer:

   • Utilizes laser/infrared dual-mode sensors, which complement each other to avoid interference from light and color, accurately identifying toilet stall occupancy status and reducing misjudgment rates.
   • Deploys industrial-grade environmental monitoring terminals to collect real-time data on ammonia, hydrogen sulfide concentrations, and temperature and humidity, providing quantitative bases for air quality assessment.

2. Cognition Layer:

   • Front-end data is transmitted via IoT to a cloud management platform, forming a unified smart public toilet guidance system backend.
   • Achieves full-element visualization, including toilet stall distribution, usage frequency, environmental indicators, etc., and supports intelligent alerts (e.g., for excessive odor or equipment failures).

3. Execution Layer:

   • Dynamically displays toilet stall occupancy and air quality through a guidance system large screen, guiding users to quickly locate available stalls and reducing queue times.
   • The system automatically generates work orders and assigns them by priority based on stall usage frequency and cleaning standards, achieving 'on-demand cleaning' and improving cleaning efficiency.

2. Engineering Implementation and Customization Capabilities

• Complex Environment Adaptation: Provides customized solutions for signal-blocking scenarios such as ancient buildings and underground spaces. For example, in the Shanghai Yu Garden project, a signal relay solution was deployed to ensure low-latency, high-reliability data transmission, overcoming communication barriers caused by thick walls and complex structures.
• Modular Design: The system supports flexible expansion and can integrate additional sensors (e.g., for pedestrian flow statistics, energy consumption monitoring) or connect to urban management platforms to meet diverse scenario requirements.

3. Technical Advantages and Industry Recognition

• Full-stack Self-Development Capability: As the original manufacturer, Deyi Environment possesses full-chain R&D capabilities from hardware to software, ensuring system stability and data security.
• Endorsement by Leading Enterprises: The solution has been validated by Fortune 500 companies and industry leaders such as China Mobile, demonstrating its technical maturity and commercial value.

This solution significantly enhances the intelligence level of public toilet management through technological integration and scenario-based innovation, providing a replicable benchmark case for smart city construction.
