| As the key supporting index of the evaluation system of the rural livable community,the environmental information index needs to be measured accurately and objectively.In order to realize the rapid detection and evaluation of comprehensive environmental information,this paper designed and developed a multi-parameter integrated environmental information detection system based on hardware integration technology,multi-sensor technology,wireless communication technology and virtual instrument technology,and realizes the detection of the air quality,water quality,soil quality,sound environment and geographic information,the main work of the paper include:(1)The overall design and hardware development of the integrated environmental information detection system.Based on the relevant standards and the analysis air quality,water quality,soil quality,sound environment and geographic information,this paper selected 22 typical parameters to detect.What's more,on the basis of the structural optimization design method,the hardware development of the portable multi parameter integrated environmental information detection system is completed.(2)The development of the software system of multi parameter integrated environmental information detection system.Based on the LabVIEW2012 platform,using modular programming ideas,the software system was developed with the function of real-time detection,dynamic display,data analysis,data query,report generation about the information of the air quality,water quality,soil quality,sound environment and geography.(3)The application of detection system in water environment assessment.Based on the analysis of the advantages and disadvantages of 7 typical models in water environment assessment model,this paper determined the 'comprehensive water quality identification index' to be the model for the system to be applied in water environment assessment.In addition,this paper completed the program design of assessment module in Lab VIEW,and successfully applied it to water environment assessment.(4)The analysis of the uncertainty of the detection system.Based on the results of the detection system applied to the water quality assessment,this paper analyzed the sources of uncertainty,and according to the synthetic principle of the uncertainty,the confidence interval of the integrated water quality index was calculated for the reliability analysis of the detection used in water quality evaluation.In view of the above,this paper developed a set of portable multi-parameter integrated environmental detection system around the current requirements of rapid detection of comprehensive environmental information,and realized the rapid collection and analysis of 22 environmental information.Furthermore,based on this system,this paper realized a comprehensive assessment of water quality,and the uncertainty of the assessment value was analyzed,which verified the reliability of the system in water quality assessment.The system has been successfully applied to relevant units. |
