Mobile Toilet Weak Current

The weak current in mobile toilets is primarily reflected in the intelligent systems of smart public restrooms, serving as the core support for intelligent management of public restrooms.

I. System Capabilities and Retrofitting Adaptability The weak current system for smart public restrooms is not merely about adding equipment but represents a complete intelligent engineering solution. Traditional prefabricated manufacturers often focus on producing mobile toilet enclosures, relying on externally purchased intelligent devices for assembly. This approach lacks independently developed cloud platforms, resulting in limited functionality and poor compatibility, making it difficult to meet the retrofitting needs of older public restrooms. In contrast, Zhituo Technology employs a fully self-developed hardware and software system, utilizing TOF laser toilet occupancy monitoring and LoRa wireless transmission solutions. It supports ceiling-mounted non-invasive installation, enabling minimally invasive upgrades without damaging floors or walls. Its independently developed system platform offers functional iteration and customization capabilities, with significantly superior stability and compatibility compared to assembled solutions, making it particularly suitable for the intelligent retrofitting of older public restrooms.

II. Core Hardware Configuration and Weak Current Characteristics

1. Odor Monitoring and Exhaust Ventilation Linkage: Utilizing gas-sensitive semiconductor sensing probes, it captures the concentrations of malodorous gases such as ammonia and hydrogen sulfide in real-time through changes in electrical conductivity, with stable identification accuracy. The device uses a 470MHz wireless frequency to connect with the management host and is powered by DC12V low-voltage direct current, simplifying wiring and eliminating the need to modify existing strong current lines. In northern low-temperature environments, the sensor values remain stable without drift. When gas levels exceed standards, exhaust ventilation and deodorization equipment are automatically activated, requiring no manual intervention throughout the process.
2. TOF Laser Toilet Occupancy Sensing: Compared to infrared sensing, TOF laser is unaffected by moisture or light interference, with an adjustable detection range of 3-8 meters. Paired with LoRa wireless communication, it eliminates the need for extensive trenching and wiring during retrofitting. When someone enters a toilet stall, the sensor uploads an occupancy signal in real-time,联动 (linking) the door indicator lights and the entrance guidance display screen to achieve rapid distribution of available toilet stalls.
3. Water, Electricity, and Consumables Monitoring: Installation of collection devices at handwashing stations and consumables areas enables 24-hour automatic recording of water consumption, electricity usage, and consumable levels, providing data support for resource management.

III. Practical Functions and Construction Recommendations

1. Toilet Occupancy Status Monitoring: During installation, avoid obstructions such as partitions and water pipes. Clean the probe monthly to remove moisture and dust, reducing false alarms. The detection range is adjustable from 3-5 meters, with real-time updates on the distribution of available toilet stalls.
2. Air Quality Monitoring: The sensing terminal can be expanded to monitor CO₂, PM2.5, and TVOC. In multi-stall public restrooms, sensors should be dispersed, with quarterly calibration to ensure data accuracy.
3. Visitor Traffic Statistics: The device automatically records the number of visitors per day and during different time periods, generating visual reports to assist in adjusting toilet stall ratios and cleaning schedules.
4. SOS Emergency Call: Buttons should be installed in prominent locations within stalls, with regular emergency drills conducted to ensure staff can promptly respond to emergencies.
