Nan'an Intelligent Mobile Toilet

Currently, there is no clear mention of a complete construction case of an 'intelligent mobile toilet' in Nan'an District, but there are fixed intelligent public toilets with multiple intelligent functions (such as the 'Tidal Toilet' on Yanyu Road), and there are also explorations of intelligent function applications in the field of mobile toilets.

Typical Case of Fixed Intelligent Public Toilet

The public toilet on Yanyu Road in Nan'an District is the first 'tidal toilet' in Chongqing. Its intelligent functions are mainly reflected in the following aspects:

• Dynamic Adjustment of Tidal Toilet Cubicles: Five additional tidal toilet cubicles are set up between the men's and women's toilets. The intelligent system automatically switches their usage directions based on real-time pedestrian traffic. During peak hours, the number of toilet cubicles for a specific gender can be flexibly increased, while during off-peak hours, some cubicles can be closed to save energy. This effectively alleviates the contradiction of 'idle men's toilets and long queues at women's toilets' in traditional public toilets.
• Real-time Monitoring of Environmental Data: The lobby is equipped with an intelligent display screen that dynamically shows air quality indicators (such as ammonia and hydrogen sulfide concentrations) and the number of available toilet cubicles, helping users quickly choose a cubicle and providing environmental maintenance references for management personnel.
• Linked Control of IoT Devices: Human body detection sensors are installed in the toilet cubicles to automatically sense usage status and activate centrifugal silent exhaust fans to ensure timely removal of odors. Electromagnetic induction valves are used in squatting pans, urinals, and washbasins, enabling 'flushing upon arrival and stopping upon departure' through infrared sensing to avoid water waste.

Exploration of Intelligence in Mobile Toilets

Although there is no clear construction of an 'intelligent mobile toilet' in Nan'an District, there have been applications of some intelligent functions in the field of mobile toilets:

• Environmentally Friendly and Energy-Saving Design: Some mobile toilets use microbial degradation technology to treat excrement, reducing sewage discharge. They are equipped with solar panels for power supply, reducing dependence on traditional energy sources.
• Portability and Modularity: Mobile toilets usually adopt lightweight materials and detachable structures, facilitating transportation and rapid deployment, and are suitable for temporary events, disaster relief, and other scenarios.
• Basic Intelligent Functions: Some products integrate sensors to monitor the occupancy status of toilet cubicles or provide cubicle navigation services through mobile apps, but their functional completeness and systematization are still inferior to those of fixed intelligent public toilets.

Potential Definition of Intelligent Mobile Toilet

Based on industry trends, an intelligent mobile toilet may refer to a movable sanitary facility that integrates technologies such as the Internet of Things, environmental monitoring, and automatic cleaning. It needs to have core functions such as dynamic adjustment of toilet cubicles, real-time feedback of environmental data, and energy conservation and consumption reduction. However, currently, there is no publicly available complete case in Nan'an District.
