Precise Project Planning in the Pre-Construction Phase
The foundation for rapid deployment lies in thorough preliminary preparation, typically completed 2-3 weeks in advance:
1.Comprehensive Site Survey and Mapping: Precisely locate all water usage points within the park. Record pipeline material, diameter, installation environment, and surrounding interference sources. Establish a complete electronic point map to avoid repeated confirmations during construction.
2.Customized Solution Design: Select appropriate water meter types based on industrial water characteristics (e.g., water quality, pressure, temperature, flow range). Simultaneously, consider signal coverage and power supply conditions to determine the wired or wireless technical route, forming a “one-meter, one-strategy” implementation plan.
3.Production Schedule Coordination: Work closely with park management to schedule construction during production low periods or planned maintenance windows, minimizing water shutdown impact. Implement segmented water shutdown strategies for key production line areas to ensure 24/7 uninterrupted water supply in core zones.
Optimized Equipment Selection and Technical Configuration
1.Wireless Communication Technology as the Driver: Prioritize wireless technologies like NB-IoT/4G or LoRa to avoid the complex conduit and cabling work of traditional wired solutions. NB-IoT/4G meters connect directly to operator networks, while LoRa meters cover large areas via a small number of concentrators, significantly reducing construction工作量.
2.Modular Pre-assembled Equipment: Choose smart water meters with quick-connect couplings for “plug-and-play” installation. Some devices support pre-configured parameters, requiring only physical installation and power-on onsite, eliminating complex parameter setup.
3.Battery-Powered Solution: Opt for long-life battery-powered water meters to circumvent challenges associated with onsite power wiring. High-quality lithium-thionyl chloride batteries can have a design lifespan of 8-10 years, eliminating the maintenance burden of frequent replacements.
Standardized Construction Process and Parallel Operations
1.Parallel Construction by Zone: Divide the park into 4-5 construction zones, each assigned an independent work crew operating simultaneously. A single crew typically consists of 3-4 personnel responsible for meter removal, new meter installation, parameter configuration, and functional testing respectively, forming an assembly-line workflow.
2.Standardized Work Instructions: Develop illustrated operation guides for each construction step, specifying tool lists, installation procedures, and quality checkpoints. This ensures uniform execution standards across different crews and minimizes rework.
3.Pre-configured Tools and Spares: Equip each construction crew with dedicated toolkits and common spare parts (e.g., seals of different specifications, adapter fittings) to reduce downtime caused by tool shortages or component mismatches.
Key Milestone Control During Onsite Implementation
Phase 1: First 24 Hours (Old Meter Removal & Basic Installation)
• Complete water shutdown procedures and safety briefings; simultaneously conduct area isolation and tool preparation.
• Remove old meters and install new meter bodies by zone; complete mechanical connections and seal testing.
• Complete installation at the remaining 50% of meter locations; focus efforts on critical production areas during night hours.
Phase 2: Next 24 Hours (Electrical Connection & Preliminary Debugging)
• Power up/activate all water meters; complete basic configuration of communication modules.
• Conduct single-meter functional testing by zone, verifying basic functions like metering, communication, and valve control.
Phase 3: Final 24 Hours (System Integration & Commissioning)
• Connect to the management platform; perform full-system data acquisition testing and exception handling.
• Complete final acceptance testing, generate system reports, and organize user training and documentation handover.
