Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 20524-2006 "Agricultural and Forestry Microclimate Observatory". This standard is compared with GB/T 20524-2006, the main technology
The changes are as follows.
--- Revised the terms "gradient observation", "photosynthetically active radiation" and "microclimate" (see 3.1, 3.2 and 3.3,.2006 editions 3.1, 3.2 and
3.3);
--- Added the term "total radiation" (see 3.4);
--- Revised the technical requirements "composition" (see 4.1, version 4.1 of.2006);
--- Revised the technical requirements "structure" (see 4.2.1, 4.2.1 of the.2006 edition);
--- Revised the technical requirements "functions" (see 4.3, 4.3 of the.2006 edition);
--- Change the technical requirements "performance" to "technical indicators", and add technical requirements for water temperature, wind direction and soil moisture in this part.
(See 4.4, 4.4.4, 4.4.5 and 4.4.8, 4.4 of the.2006 edition);
--- Revised the maximum allowable error of the technical indicator "air temperature" (see 4.4.1, 4.4.1 of the.2006 edition);
--- Change the technical indicator "relative humidity" to "air humidity" and modify the maximum allowable error (see 4.4.2,.2006 edition)
4.4.2);
--- Modified the measurement range of the technical index "wind speed", the maximum allowable error, the starting wind speed, and removed the wind resistance (see 4.4.6,.2006).
Version 4.4.4);
---Modified the "insulation resistance" in the technical requirements "Electrical Safety" (see 4.5.1, 4.5.1 of the.2006 edition);
--- Revised the technical requirements "maximum allowable error of clock travel time" (see 4.6, 4.6 of.2006 edition);
--- Modified the power supply adaptability "DC power supply" (see 4.7.2, 4.7.2 of the.2006 version);
--- Revised the environmental adaptability "work environment" (see 4.8.1, 4.9.1 of the.2006 edition);
--- Increased test methods "water temperature", "soil moisture" and "wind direction" (see 5.4.1, 5.4.3 and 5.4.4);
--- Change the test method "performance" to "technical indicators", and test the technical indicators such as "air temperature", "air humidity" and "wind direction"
The preparation and test methods refer to relevant standards (see 5.4, 5.4 of.2006 edition);
--- Removed the logo "National Production License Mark" (see.2006 version 7.2.4).
This standard was proposed by the China Meteorological Administration.
This standard is under the jurisdiction of the National Standardization Technical Committee for Meteorological Instruments and Methods of Observation (SAC/TC507).
