Zhejiang Mobile Smart Toilet Standard

The Zhejiang Mobile Smart Toilet Standard can refer to the Hangzhou Smart Public Toilet Technical Specification, covering six core dimensions: perception, data, decision-making, execution, system robustness, and performance evaluation, while forming a technical framework by integrating key parameters of 5G toilets.

1. Perception and Response System
Environmental and status monitoring are achieved through multiple types of sensors: gas sensors continuously detect ammonia and hydrogen sulfide concentrations to ensure air quality compliance; human infrared sensors and door magnetic sensors jointly determine toilet stall occupancy status, with data collection accuracy meeting dynamic response requirements. Sensors must exhibit high stability to support the accuracy of subsequent control logic.

2. Data Flow and Integration Mechanism
Raw data is transmitted to local control units via wired or wireless communication protocols (e.g., LoRa, NB-IoT), where signal conversion, filtering, and timestamp marking are performed. Based on predefined rules, local units filter valid data and upload only key information to the cloud or regional management platform, reducing the pressure of invalid data transmission.

3. Platform Decision-Making Logic
Cloud-based algorithm models compare historical and real-time data to achieve intelligent regulation in three aspects:

• Resource Allocation: Predict peak-hour foot traffic to dynamically adjust cleaning staff scheduling;
• Environmental Adjustment: Automatically regulate lighting power based on light intensity and foot traffic density to reduce energy consumption;
• Consumables Management: Monitor toilet paper and hand sanitizer levels through weight or photoelectric sensors, triggering automatic replenishment orders.

4. Execution Terminal Collaborative Control
Decision instructions are issued to terminal devices such as variable-frequency fresh air units and smart water-saving fixtures: the fresh air system adjusts operating power based on the Air Quality Index (AQI); smart fixtures integrate sensor-activated and timed flushing modes, reducing water consumption by over 30% compared to traditional fixtures; information display screens show real-time toilet stall status and environmental data.

5. System Robustness Requirements

• Electrical Safety: Equipment must have an IP54 or higher protection rating in humid environments, with moisture- and corrosion-resistant wiring;
• Data Security: Local data is encrypted for storage, with SSL/TLS protocols used during transmission and hierarchical access control implemented;
• Maintainability: Key sensor modules support fault self-diagnosis and status reporting, while major equipment provides standardized interfaces for rapid maintenance.

6. Performance Evaluation Quantitative Indicators
Set targets for reducing daily average water and electricity consumption per public toilet (e.g., a 20% reduction in water consumption), while requiring an environmental quality compliance rate (e.g., ammonia concentration ≤ 0.3 mg/m³) of no less than 95%.

Additional: Key Parameters for 5G Toilets
Prefabricated steel structure equipment rooms have a penetration rate exceeding 62%, using hot-dip galvanized steel components with a salt spray corrosion resistance time of ≥1200 hours and a design lifespan of 15 years; 5G IoT modules must support access by major operators, enabling real-time data return from ≥6 types of sensors; modular installation takes ≤72 hours, with on-site wet work accounting for ≤10%.
