Locations of Smart Mobile Toilets in Chongqing

The publicly disclosed locations of smart mobile toilets in Chongqing include beneath Huanghuayuan Bridge in Jiangbei District, beside Qiujiawan Rail Transit Station in Nan'an District, and Caixin Plaza in Jiangbeizui. The public toilet beside the bus stop at Daqing Village on Hongshi Road, although not explicitly labeled as a smart toilet, features some smart design elements.

1. Public Toilet beneath Huanghuayuan Bridge in Jiangbei District
This toilet is a typical smart mobile toilet, with core configurations including intelligent cleaning robots, toilet stall guidance systems, and IoT sensing devices. The intelligent cleaning robots can automatically complete tasks such as floor cleaning and disinfection, reducing manual intervention. The toilet stall guidance system displays the occupancy status of toilet stalls in real-time through electronic screens, preventing users from waiting blindly. The IoT sensing system monitors environmental data such as temperature, humidity, and ammonia concentration, and feeds this information back to the management terminal through a cloud platform for dynamic regulation. Such designs significantly enhance the hygiene level and usage efficiency of the toilet.

2. Public Toilet beside Qiujiawan Rail Transit Station in Nan'an District
This toilet employs modular smart toilet technology, with the main structure prefabricated in a factory and then transported to the site for assembly, requiring only a few days for construction. The modular design enables rapid deployment, making it particularly suitable for emergency scenarios (such as large-scale events, post-disaster reconstruction) or temporary needs (such as construction areas). Its smart features may include intelligent lighting, automatic ventilation, and remote monitoring systems, but the specific configurations are subject to the actual situation on-site.

3. Public Toilet at Caixin Plaza in Jiangbeizui
This toilet is a representative example of modular smart mobile toilets, with an on-site installation period of only one day. Its core smart technologies include a smart IoT management system (which can monitor equipment operation status and energy consumption data in real-time) and vacuum suction water-saving technology. The vacuum suction system reduces flushing water volume through negative pressure principles, saving over 60% of water compared to traditional toilets and meeting green building standards. Such toilets are often deployed in commercial districts or areas with high pedestrian traffic to meet high-frequency usage demands with efficient services.

4. Public Toilet beside the Bus Stop at Daqing Village on Hongshi Road
Although not explicitly labeled as a smart toilet, this toilet incorporates humanized smart elements in its design: barrier-free facilities (such as ramps and handrails) meet the needs of special groups; child-specific equipment (such as small toilets and washbasins) enhances convenience for families; and a 'Worker's Harbor' provides rest seats and water dispensers, demonstrating care for outdoor workers such as sanitation workers. Although such designs do not rely on high-tech equipment, they achieve service smartness through functional optimization.
