Mobile Toilet Self-Service QR Code System
The mobile toilet self-service QR code system is a public toilet management system that combines QR code technology with intelligent management to achieve convenient use, safety monitoring, or rational resource allocation, with different application forms in various scenarios.
In the fee-based management scenario, taking a mobile public toilet in Fujian as an example, this system achieves precise association between fees and usage. When a user arrives at the toilet door, the system first checks if there is someone inside to avoid conflicts. After the user scans the code, the door automatically locks within 5 seconds to protect the user's privacy. A fee-charging QR code is placed nearby. After the user pays 10 yuan, a page pops up on their phone with options for 'Open' and 'End Order'. By clicking 'Open', the user can use the toilet normally, and the phone screen displays a countdown to remind the user of the usage time. If the usage exceeds the time limit, the user can choose to renew the fee to continue using or stop and end the order midway. This model is convenient for users and provides a reasonable fee-based management method for public toilet operators, helping to maintain the normal operation and hygiene of public toilets.
In the safety monitoring scenario, the QR code door-opening smart system installed in some public toilets in Pudong focuses on ensuring user safety. After citizens scan the QR code at the public toilet entrance to enter and use it, the system monitors the toilet usage time in real-time. Once it detects that the usage time exceeds a reasonable range of 15 minutes, the system automatically notifies the night-shift staff to contact the citizens. This function is of great significance in preventing accidents, especially during special periods such as at night, when it can promptly detect possible emergencies, such as users suddenly falling ill, and provide the possibility for timely rescue.
In the resource allocation scenario, the smart toilet paper dispensers equipped in some public toilets in Xiong'an New Area achieve rational allocation of toilet paper through QR code technology. Citizens can open WeChat on their phones and scan the QR code on the device to get toilet paper for free, with the whole process taking only a few seconds. This method not only avoids the waste of toilet paper but also meets the actual needs of citizens, improving the utilization efficiency of public toilet resources.
