Introduction

Interpretation of the core content of the standard

Technical dimensions	QX/T523-2019 requirements	Industry comparison benchmarks
Measurement range	30m-7500m	Conventional equipment 50m-5000m
Cloud detection capability	≥3 layers	Generally 2 layers
Environmental adaptability	-45℃~50℃/5%~100%RH	-30℃~45℃/10%~90%RH

Details of key technical requirements

1. Measurement performance

The standard stipulates that the laser ceilometer must meet the following requirements:

Cloud high resolution ≤10m (the actual measurement verification requires the use of three-level targets of 50m±10m, 500m±50m, and 3000m±300m)
Fixed target ranging error ±10m
Laser repetition frequency ≥2.5kHz

2. Environmental adaptability

The application case of a meteorological station in Inner Mongolia shows that the equipment needs to withstand:

Continuous operation at -40℃ low temperature in winter
Salt spray corrosion during summer sandstorms
Vibration shock under typhoon weather (5m/s² acceleration)

Implementation suggestions

Main points for procurement acceptance

Focus on verifying Group A inspection items (cloud height range, electrical safety, etc.)
Suppliers are required to provide a complete electromagnetic compatibility test report (GB/T17626 series)
On-site acceptance should include a 72-hour continuous operation test

Operation and maintenance management specifications

Maintenance items	Period	Standard basis
Optical window cleaning	Weekly	4.3 Appearance requirements
Power system inspection	Monthly	4.1.5 Electrical Specifications
