1. Mobile Six-in-One Intelligent Water Purification Device

Product Overview
1. Control Method: HMI Human-Machine Interface
Control main functions: pump control / liquid level display / pH conductivity monitoring / filter cartridge replacement reminder / cleaning settings

①. Equipment Overview
This device is an integrated "6-in-1" water purification control system, featuring HMI (Human-Machine Interface) control that allows users to set various parameters and view system status directly on the screen.
The system integrates functions such as pump control, liquid level monitoring, pH and conductivity detection, filter cartridge replacement reminders, and water softener cleaning settings, enabling fully automated management of the entire process—from water purification to water supply.
The control core is based on a computer-controlled screen with A1 and RS485 communication capabilities, featuring a mobile structure that makes installation and maintenance easy. It’s suitable for various water-use scenarios, such as restaurants, offices, schools, small-scale processing plants, and even family villas.

②. System Components

③. Main Functions
1. Pump start/stop control: Supports both automatic and manual operation; an emergency stop switch allows for forced shutdown. 2. Liquid level monitoring display: Features an immersed-type liquid level sensor with RS485 communication, providing real-time graphical visualization. 3. pH detection: Displays the water body’s pH level in real time and triggers an alarm if the value exceeds the set limit.
4. Conductivity Monitoring: Monitors the conductivity of raw water and purified water to assess the filter cartridge's condition. 5. Purified Water Usage Countdown: Displays a countdown timer for filter cartridge usage, automatically alerting you when it’s time to replace the cartridge. 6. Soft Water Regeneration Settings: Allows you to set automatic regeneration or backwashing cycles as needed.

⑦. Water Purification System Process Flow

The system's overall flow from right to left

1. Raw water entry stage:
Tap water enters the raw water tank through an inlet solenoid valve; the raw water tank is equipped with a level sensor (submersible, 4–20mA) to monitor the liquid level—when the level is low, the solenoid valve opens to replenish water, and when the level is high, the solenoid valve closes.
2. Preprocessing stage.
The raw water undergoes primary purification sequentially through a pre-filter, an ultrafiltration water purifier, and a water softening filter; effectively removing particulate impurities, rust, bacteria, calcium and magnesium ions, and more.
3. Water Quality Monitoring Phase:
Configure the pH sensor (PH101) and the conductivity sensor (EC101), and connect them to the HMI via RS485 to display water quality parameters.

Can be used for alarm purposes or to determine water quality compliance.
4. Water Discharge Monitoring Phase:
Install an ultrasonic water meter on the outlet pipeline to provide real-time feedback on the water flow rate, which is then uploaded to the HMI via RS485.
Can be used for operation records and water usage statistics.
5. Pressurized Water Supply Stage:
Purified water is delivered to users via an intelligent self-priming booster pump connected to a pressure tank system.
The control cabinet manages the pump's start and stop (K1), enabling interlocked control via liquid level and pressure. Pressure control is achieved by setting start/stop conditions—such as pressure or water level thresholds—through the HMI program.

⑧. Control Logic Description

Liquid Level Control:
Liquid level → Lower limit value: Open the drain solenoid valve;
Liquid level > Upper limit → Shut off the solenoid valve.
Manual start function.
External buttons input to the HMIDI port;
The pump can be forcibly started during emergencies or debugging, bypassing the level detection process.
Automatic/Manual Switching:
HMI interface allows switching between "Auto Mode" and "Manual Mode";
Automatic mode is controlled by level/sensor logic, while manual mode operates the pump via HMI buttons or external buttons.
Security Protection and Alarm:
The liquid level sensor is malfunctioning, and the absence of a signal can trigger an alarm notification. Additionally, alarm reminders can be set up for situations where the pH or EC value exceeds the specified limits.

⑨. HMI Signal and Communication Architecture

AI Input: Submersible Level Sensor (4–20mA); Smart Self-Priming Pump: Inlet Water Solenoid Valve
DI Input: Connects to an external manual button;

RS485 Communication: Connecting PH101, EC101, Ultrasonic Water Meters, and Level Sensors

The HMI interface displays liquid level values, operating status, control buttons, alarm information, and more.

⑩. Interface Diagram

Below is a schematic diagram of the HMI interface for the 6-in-1 water purification system. Users can operate the system via the touch screen, allowing them to view real-time system status, liquid levels, conductivity, pH levels, operation countdowns, and more—while also enabling manual control and parameter settings.
