Beijing Smart Mobile Toilet
The Beijing Smart Mobile Toilet represents an innovative achievement that deeply integrates technology and environmental protection, enhancing resource utilization efficiency, optimizing management and maintenance models, and strengthening user experience and barrier-free services through intelligent technologies.
1. Water-saving Technology: Efficient Utilization of Water Resources
The Beijing Smart Mobile Toilet employs the "Smart Micro-flush" technology, achieving precise water conservation by differentiating between flush volumes for solid and liquid waste. For example, the pilot public toilets in the sub-center have a water-saving rate exceeding 90%, with an average flush volume of only 0.75L per person per use, significantly lower than the standard of over 6L in traditional public toilets. This technology, independently developed by Beijing Aibei Space Technology Co., Ltd., combines odor prevention, clog prevention, and anti-freezing functions, reducing water consumption and alleviating sewage discharge pressure, aligning with green environmental protection principles.
2. Intelligent Sensing System: Automation and Precise Control
The toilet stalls are equipped with intelligent sensing devices that automatically identify the type of user activity and classify the flush accordingly, avoiding ineffective water use. Physical door locks are replaced with non-contact sensing devices, with the door status (e.g., occupied/vacant) uploaded in real-time to the management terminal for easy monitoring by operation and maintenance personnel. Additionally, the lighting and water systems incorporate sensing modules that automatically switch to low-power mode when unoccupied, further reducing energy consumption.
3. Environmental Monitoring and Dynamic Regulation
Through devices such as air composition analyzers and particulate matter sensors, the system continuously monitors ammonia and hydrogen sulfide concentrations, as well as air quality indices, and links with ventilation and air purification systems to maintain a comfortable internal environment. For example, when odors or dust exceed standards, the system automatically activates purification equipment; light sensors adjust indoor lighting based on natural light intensity, achieving dynamic energy optimization.
4. Predictive Maintenance and Consumable Management
Paper towel dispensers and soap dispensers are equipped with weight or optical sensors to measure remaining quantities in real-time. When stock falls below a safe level, the system automatically generates alerts and pushes them to the maintenance personnel's terminals, enabling data-driven predictive replenishment. This function reduces the frequency of manual inspections while preventing service disruptions due to material shortages.
5. Cleaning Operation Optimization: Data-driven Efficiency
Floor moisture sensors and image recognition modules jointly assess cleanliness levels, with the system calculating optimal cleaning times based on usage frequency, environmental data, and historical cleaning records through algorithmic models, and generating task orders. This intelligent scheduling reduces resource waste and ensures the public toilets remain in good hygienic condition.
6. Guidance System and Barrier-free Design
External displays show toilet stall occupancy in real-time, with some systems using graphics or color blocks to display the overall status of adjacent restrooms, aiding users in quick selection. Additionally, some toilets feature barrier-free stalls equipped with child-sized toilets, baby changing stations, safety handrails, and emergency call devices, providing safe and convenient independent spaces for special groups.
7. IoT Architecture: Data Closed-loop Management
Sensors act as terminal nodes to collect data, which is transmitted via wireless networks to local or cloud servers. Management software stores and analyzes the data, issuing control instructions (e.g., automatic flushing, activating purification equipment) based on preset rules, forming a closed loop of "sensing-processing-execution" to enhance management precision.
