Introduction
Analysis of the core content of the standard
| Technical modules | Core requirements | Typical indicators |
|---|---|---|
| System architecture | Three-level networking of telemetry station-central station/relay station | Monthly average smooth rate ≥95% |
| Communication networking | Ultra-short wave/mobile/satellite multi-channel backup | Bit error rate ≤1×10-4 |
| Data acquisition | Accuracy classification of water level meter/rain gauge | Water level level I error ±1cm |
Key technical requirements
1. Equipment selection specifications
Sensors must meet the following requirements:
- Tipping bucket rain gauge: resolution 0.1~1.0mm, MTBF≥25000h
- Float water level gauge: Level I accuracy ±1cm, lightning protection grounding resistance <10Ω
2. Communication network design
| Communication mode | Applicable scenarios | Technical parameters |
|---|---|---|
| Ultra-short wave | Line-of-sight transmission within 20km | Gain 6-12dB, VSWR <1.5 |
| NB-IoT | Wide-area low-power coverage | Interface rate 9600bps |
Implementation Suggestions
System Construction Process
- Preliminary Survey:Complete 85% site channel testing
- Equipment Installation:Solar panel inclination ≥ local latitude +5°
- Acceptance Assessment:Continuous trial operation including flood season
Operation and Maintenance Guarantee Measures
Configure 15% spare parts, establish a three-level maintenance system (daily/regular/emergency), and focus on monitoring:
- Battery voltage fluctuation range: nominal value ±20%
- Data reissue mechanism: support up to 15 days of historical data
