Jiangsu Mobile Smart Toilet System

The Jiangsu Mobile Smart Toilet System is an intelligent management system that integrates multiple components and technological modules. It achieves environmental monitoring, facility management, user guidance, and data-driven operational optimization through the collaborative work of physical and digital components.

I. Environmental Sensing and Data Acquisition Components
The system achieves comprehensive monitoring through various sensors:

1. Space Occupancy Monitoring: Utilizes infrared, ultrasonic sensors, or millimeter-wave radar to determine in real-time whether a stall or area is occupied, providing basic data for toilet stall status displays.

2. Environmental Quality Monitoring: Integrates ammonia and hydrogen sulfide sensors to monitor odor levels, temperature and humidity sensors to record environmental parameters, and PM2.5 sensors to monitor dust concentration, ensuring air quality standards are met.

3. Facility Status Monitoring: Flow sensors monitor water usage, liquid level sensors monitor the levels in fecal tanks/water tanks, door magnetic switches record the opening and closing status of toilet doors, and photoelectric or weight sensors monitor the remaining amounts of soap dispensers and paper towel boxes, enabling early warning of consumables.

4. Auxiliary Acquisition Equipment: Cameras are installed in public areas (such as washing areas and corridors) to monitor foot traffic and order on a macro level; one-touch call buttons or touchscreen terminals collect user-initiated requests, enhancing service response efficiency.

   II. Data Aggregation and Edge Processing Components
   The IoT gateway serves as the core hub, uniformly managing all sensors, converting communication protocols (such as Modbus, ZigBee), and aggregating data before uploading it to the cloud via wired (Ethernet) or wireless (4G/5G, fiber optic) connections. Some systems integrate edge computing nodes to preprocess raw data, such as calculating toilet stall occupancy rates in real-time, determining whether environmental parameters exceed standards, and automatically triggering local control strategies like exhaust fans to reduce reliance on the cloud.

   III. Network Transmission and Interactive Guidance Layer
   The system selects network access based on the scenario: urban fixed toilets prioritize fiber optics or broadband, while parks and scenic areas use 4G/5G. Entry electronic screens dynamically display floor plans, using color coding to indicate toilet stall status, air quality, and consumable levels; voice announcements or wireless network signals further meet diverse needs, enhancing the user experience.

   IV. Data Aggregation and Operational Optimization
   Anonymized data on usage frequency, peak times, and consumable consumption rates is uploaded to the cloud. Through long-term trend analysis, the system predicts consumable replenishment times, identifies facility wear risks, optimizes inspection routes and work plans, and achieves a transition from reactive response to proactive management.

   V. Privacy Security and Compliance
   The system adheres to the principle of “only collecting status, not identifying individuals.” Sensors record abstract events (such as object movement), avoiding biometric identification like facial features or body shapes. Data transmission and storage are fully encrypted, with regular automatic deletion, eliminating privacy leak risks from a technical standpoint.
