SUNPN Smart Public Toilet System: Office Building Restroom Monitoring Case

Renovating restrooms in office buildings poses a key challenge: synchronizing stall occupancy status, environmental metrics and user guidance. The SUNPN Smart Public Toilet System consolidates red‑green stall occupancy status as well as environmental data onto an LCD display screen. It delivers a practical reference for retrofitting existing office buildings with minimized re‑wiring and optimized restroom navigation.

1. Background & Pain Points: Why Adopt SUNPN Smart Public Toilet System for Office Premises

Office‑building restrooms see concentrated peak‑hour usage. Staff may walk all the way to the restroom entrance only to find every stall occupied. Facility managers also require real‑time visibility of indoor environmental conditions. This project addresses two core requirements: restroom stall occupancy monitoring & navigation, and restroom environment monitoring. The implementation covers status collection, on‑site indication and centralized display for 7 restroom stalls.



 

2. Product Functions of SUNPN Smart Public Toilet System

2.1 System Composition

The office‑building Smart Public Toilet System can be divided into three layers: perception, transmission and application. Wireless energy‑harvesting door locks and environmental sensors perform data collection; wireless receiving modules and edge‑computing gateways handle data transmission; stall indicator lights and LCD large screens present occupancy status and environmental readings to end‑users and facility administrators.

2.3 Monitoring Principle of SUNPN Smart Public Toilet System

When users turn the door handle, the built‑in energy‑harvesting module converts mechanical motion into electric energy and triggers a low‑power wireless signal. The receiver synchronizes the indicator light: red light = stall occupied (door locked); green light = stall vacant (door unlocked). Status data is uploaded via the gateway to the guidance display interface. Two environmental sensors collect metrics including temperature, humidity, PM2.5, ammonia and hydrogen sulfide to support facility inspection work.

2.4 Installation & Deployment

Prior to installation, verify door‑panel thickness, door‑swing direction and sleeve‑screw specifications, then finalize mounting positions for door locks, receivers and indicator lights. No signal cabling is needed between door locks and receivers. However, receivers, indicator lights, gateways, sensors and display screens still require power supply and communication wiring per construction drawings. After installation, conduct one‑by‑one validation for red/green status switching of all 7 stalls, screen display outputs and environmental data reporting.

3. Problems Solved by SUNPN Smart Public Toilet System

Entrance display screens plus stall‑mounted indicator lights make vacancy status highly visible, eliminating the need for users to check stalls one by one. Centralized environmental data delivers objective reference for cleaning patrols. Note: Although the system collects status and sensor data, it cannot directly eliminate odors or guarantee management outcomes. Real‑world improvements still rely on manual cleaning, routine maintenance and abnormal‑event response workflows.

 

4. Solution Selection Guidance

Wired solutions are preferred for new‑build projects. Wireless door‑lock setups are highly recommended for retrofitting existing buildings.

• For basic stall‑navigation only: configure door locks, wireless receivers and stall indicator lights.
• For environmental‑data display in addition: add sensors, edge‑computing gateway and LCD display screen.

Extended modules such as cloud management platform, mini‑program, passenger‑flow statistics, consumable monitoring and emergency‑call management are available upon separate evaluation. These modules are not included within the standard delivered scope.

5. Project Hardware Bill‑of‑Materials

Hardware scope for this SUNPN Smart Public Toilet System office‑building deployment includes: 7 × wireless energy‑harvesting door locks, 7 × stall occupancy indicator lights, 2 × environmental sensors, 1 × edge‑computing gateway, 1 × LCD large display screen, plus supporting wireless receiving modules and power‑supply accessories.

The door locks generate power mechanically via handle operation and require no batteries. Bar‑shaped indicator lights support multiple dimensions and communication options, which shall be determined according to on‑site design requirements.
 

6. Frequently Asked Questions (FAQ)

Q: Do the door locks of the Smart Public Toilet System require battery replacement?
A: No batteries are needed.

Q: Does the wireless setup mean zero cabling work in total?
A: No. The wireless design removes signal wires between door locks and receivers. Other devices still require power wiring; gateways, sensors and display screens also need connection according to the technical solution.

Q: Can the system be expanded with cloud‑platform management features?
A: Modules such as cloud platform and mini‑program can be assessed on request. Clarifications are required for data access rules, display terminals and operation‑maintenance arrangements. These functions are not part of the standard delivered scope.
