Grouting & Water Pressure Monitoring Base Station (On-site Core Unit)

Hardware：Military-grade industrial computer.
Key Functions：
- Real-time Data Acquisition：Collects key grouting parameters: flow rate, pressure, water-cement ratio (density), displacement (heave/lift monitoring), liquid level, etc.
- Intelligent Control：
  - Automates control of grouting pumps, mixing tanks, high-pressure valves, flushing valves, and slurry supply valves.
  - Executes complete grouting sequences: fissure flushing → simple/five-point water pressure testing → pipe volume measurement → conventional/GIN grouting.
  - Supports automatic/manual modes for grouting line cleaning.
- Safety Features：Comprehensive alarm system coupled with pressure protection devices.

3. Data Acquisition Controller (Dual-channel for Data & Control)

(Including Data Collector + Equipment Controller, enabling dual channels for data and control.)

Data Collector(Data Channel Core):
- Features a built-in 10-channel, 12-bit A/D converter.
- Collects real-time current signals from sensors (flow, pressure, density, displacement, level) and transmits the converted digital data to the base station.
- Receives control commands from the base station and relays them to the Equipment Controller.
- Enables automatic pressure adjustment by controlling pressure regulation devices based on stage-specific grouting requirements.
Equipment Controller (High-power Control Unit):：
- Control Modes: Automatic / Semi-automatic / Manual.
- Control Channels: Single or dual channel.
- Controlled Devices: Grouting pumps, mixing tanks, automatic pressure regulating valves, flushing solenoid valves, drain valves.
- Communication: RS485 interface, supporting automated, semi-automated, and manual independent operation.

The Automatic Pressure Regulating Valve (comprising stepper motor, PLC driver, high-pressure valve, etc.) acts as the actuator for the Equipment Controller, enabling closed-loop pressure control (host computer compares pressure differential →drives stepper motor→adjusts high-pressure valve).

4. Terminal Sensors

Deployed on-site to measure physical parameters: flow, pressure, water-cement ratio (density), displacement (heave), liquid level, etc.
