1. Introduction
2. Hardware System Design
2.1 Modular Water Purification System
Five - stage Filtration Technology:
PP Cotton Filter (5μm): Filters out large particles such as sediment and rust.
Activated Carbon Filter: Adsorbs residual chlorine, organic matter, and odors.
RO Reverse Osmosis Membrane (100GPD): With a desalination rate of ≥98%, it removes heavy metals, bacteria, etc.
Post - activated Carbon Filter: Improves the taste of water, ensuring it is sweet and clear.
UV Sterilization Module: Equipped with a 254nm ultraviolet lamp, with a contact time of ≥1 second to kill microorganisms.
Water Quality Monitoring Sensors: Continuously detect TDS value, pH value, and turbidity. The machine will automatically shut down in case of abnormal conditions.
2.2 Intelligent Water Vending Terminal
Multiple Payment Methods: Coins, banknotes, IC cards, credit cards and other payment methods.
Large - capacity Water Tank: Comes with a 100L food - grade PE water tank,tank capacity can be customized according to customer requirements .
Anti - vandalism Design:
Made of stainless steel, it is corrosion - resistant and resistant to violent disassembly.
3. Cloud - based Management Platform
3.1 Remote Monitoring and Maintenance
Device Status Monitoring:
Real - time display of filter life, water tank level, and fault codes (e.g., E01 = RO membrane blockage).
Abnormal alarm: Sends notifications via SMS and APP (e.g., when filter life is less than 10%).
3.2 Data Visualization and Analysis
Water Quality Data Dashboard: Displays TDS values and microbial test results of each device.
Sales Data Statistics: Counts daily/monthly water sales volume and payment method distribution to optimize operational strategies.
3.3 Intelligent Scheduling System
Filter Replacement Reminder: Dynamically adjusts the filter replacement cycle based on water quality data (from the traditional fixed 3 - month cycle to an intelligent cycle of 1 - 6 months).
