Introduction to the Functions of Public Mobile Toilets

Public mobile toilets have various functions, including overall mobility and setup, intelligent environmental protection, intelligent public toilet systems, and towing capabilities. Here is a detailed introduction:

Overall Mobility and Setup Function: One of the most significant features of public mobile toilets is their ability to be moved as a whole. They can be flexibly set up according to the fixed or temporary needs of different locations and venues, providing toilet services to the public and customers. Their wide range of applications covers stations, docks, tourist attractions, villa areas, newly built residential areas, large construction sites, squares, densely populated public places, and bustling commercial streets. This flexibility enables public mobile toilets to quickly respond to toilet demands in various scenarios, effectively addressing the issue of fixed locations and difficulty in adjustment associated with traditional fixed toilets.

Intelligent Environmental Protection Mobile Toilet Function: Taking the epidemic prevention-type intelligent environmental protection mobile public toilet used during the Winter Olympics as an example, it features ultra-tech functions such as wave-to-open doors, wave-to-replace seat cushions, and wave-to-flush. These functions not only enhance the user experience but also reduce direct contact between people and toilet facilities, lowering the risk of cross-infection. They played a crucial role during the epidemic prevention and control period and also demonstrated the innovation of public mobile toilets in terms of environmental protection and intelligence.

Intelligent Public Toilet System Function: The intelligent public toilet system based on STM32 offers a rich variety of functions. The automatic flushing function detects whether someone is using the toilet through infrared obstacle avoidance sensors, enabling automatic flushing after use or timed automatic flushing every 2 minutes, which is both convenient and water-saving. The ventilation function uses MQ136 hydrogen sulfide sensors and MQ137 ammonia sensors to detect the concentrations of hydrogen sulfide and ammonia. When the concentrations exceed the standard, fans are automatically turned on for ventilation, keeping the toilet air fresh. The alarm function emits an alarm through a buzzer when gas data exceeds the standard, reminding management personnel to handle it promptly. The footfall detection function uses infrared beam sensors to monitor the toilet's usage in real-time. The real-time positioning function utilizes GPS modules to facilitate toilet management and scheduling. The data display and control function shows data in real-time through a display screen, transmits data to the cloud platform via a Wifi module, and allows APPs to obtain platform data for display and control. The line buttons can also be used to modify preset values, achieving intelligent toilet management.

Towing Toilet Function: Towing toilets are equipped with an inlet hole at the back, which contains a main control switch for convenient circuit control and management. The back adopts an upward-pushing window design, and each toilet cubicle has a ventilation device, ensuring good ventilation inside the toilet and enhancing user comfort.
