Shanghai Mobile Smart Toilet Solution
The Shanghai Mobile Smart Toilet Solution integrates IoT, AI algorithms, and ecological technologies to build an intelligent and resource-efficient public health service system.
Technical Architecture and Core Functions
The solution is based on IoT sensing, deploying nearly a hundred types of devices such as laser sensors and environmental monitors to collect real-time data on toilet stall status, air composition (e.g., ammonia and hydrogen sulfide concentrations), temperature, and humidity, with millisecond-level data transmission via 5G networks. AI algorithms predict pedestrian flow patterns and equipment failures, dynamically adjusting ventilation and lighting system intensity while optimizing cleaning resource scheduling. For example, the Guangzhou Zhongqi Technology cloud platform monitors ammonia concentration curves in over 300 public toilets, and Xuzhou Airport reduced cleaning response times to within 15 minutes using this platform. Interactive guidance interfaces provide real-time toilet stall navigation and peak-hour alerts through integrated guide screens, stall status indicators, and mobile terminals, reducing user waiting times.
Innovative Design and Scenario-Based Applications
The solution tailors functions to different scenarios:
- Tidal Toilet Stalls: Shenzhen Sports Center uses movable partitions to dynamically adjust the ratio of male to female stalls, reducing female queue times by 70%.
- Emergency Function Integration: The Chengdu World Games smart toilets are equipped with AED emergency equipment and fresh air systems for harmless waste disposal; public toilets in Ganjingzi District, Dalian, are fitted with laser fall alarms that trigger within 3 seconds of an incident.
- Elderly-Friendly Design: Chongqing Shuanggui Lake Scenic Area installs millimeter-wave fall detectors and one-touch emergency buttons, along with safety features like anti-collision rounded corners, to enhance safety for elderly users.
Operation and Maintenance System and Management Model
The solution establishes a closed-loop operation and maintenance mechanism, with Shanghai public toilets using a “one-code supervision” system for citizen reporting and evaluation via QR codes, reducing closed-loop processing time to 2 hours. Ecological recycling technologies significantly reduce resource consumption: Zhonghe Qingshan Company’s septic tank-free technology cuts waste treatment energy consumption by 60%, Yuanting Ecological Toilet’s dual-degradation system saves 200 tons of water annually, and the Dunhuang Mogao Caves case demonstrates direct use of treatment byproducts as organic fertilizer. For energy self-sufficiency, the Shenzhen Bay Park smart toilet achieves 100% sewage recycling through wind-solar power generation, while the Tianjin Eco-City project meets 70% of equipment power needs via photovoltaic power.
Typical Cases and Data Support
As of 2025, over 3,000 smart public toilets have been deployed nationwide, with Shanghai’s AI-powered toilet quality recognition system trending on social media. The Guangzhou Zhongqi Technology cloud management platform enables remote control of over 2,000 public toilets across China, and Shenzhen has deployed unmanned cleaning robots in 20 public toilets. The Beijing Winter Olympics adopted unmanned disinfection modules with automatic UV sterilization every 4 hours; in Sanming City, Fujian, 30 smart public toilets reduced deodorization equipment energy consumption by 28% through environmental data linkage.
