- Abstract:
- According to the production practice for many years,many application characteristics of information collection technology in solar greenhouse were analyzed,mainly including:need hardware equipment in bad environment with supernormal reliability,the field staff science and technology quality were generally low should be realized unattended and avoid operationalization;in order to reduce the hardware cost system should be broad compatible with all kinds of cheap non-standard signal probe;automatic control multiple factors should be adopted numerical logic mixed control;effect optimization and dynamic threshold value;the historical data timing trace analysis results as system prompt variable;system structure simplification;low speed of response and supernormal delay sex;need a large number of experimental data support;mechanical movement kind of solar greenhouse environment regulation control execute equipment reliability needs high.On this basis,the solution for solar greenhouse environment information collection technology were put forward to provide a basis for improvement.
