Device and method of acquiring agricultural non-point source pollution in-situ survey information

Abstract

The invention discloses a device and a method of acquiring agricultural non-point source pollution in-situ survey information. The device comprises an acquisition device, a verification device and a storage device, wherein the acquisition device is sued for acquiring survey information filled according to a preset survey table; the verification device is connected with the acquisition device for verifying the survey information acquired by the acquisition device according to a multi relationship between survey indexes in the survey table and a data range; and the storage device is connected with the verification device for filing the survey information in a survey table form in a condition in which the survey information is verified to be correct. In view of difficult problems that whether to carry out household survey can not be verified, the index multi relationship can not be verified, a data filling process is complicated and the like, survey positions can be automatically recorded, research object image information is recorded, the multi relationship for all indexes is verified, the data range is verified, the data operation process is simplified, the survey data can be automatically transmitted, data management is realized, the agricultural non-point source pollution survey data precision is improved, and the agricultural non-point source pollution survey working efficiency is enhanced.

Description

Technical field [0001] This field relates to the field of information collection, and in particular to a device and method for collecting agricultural non-point source pollution in-situ survey information. Background technique [0002] my country's agricultural non-point source pollution has become one of the main sources of environmental pollution. The general survey of agricultural pollution sources is an important means to find out the base number of pollutants produced and discharged in the process of agricultural production in my country. In the first national general survey of agricultural pollution sources, we systematically, scientifically and accurately calculated the 2007 national agricultural sources of planting, livestock and poultry breeding, and aquaculture through comprehensive surveys, sampling surveys, and coefficient monitoring. The discharge of pollutants from domestic industries and rural domestic sources in key river basins. [0003] Agricultural non-point so...

AI Technical Summary

Problems solved by technology

[0004] In the above process, the investigation of agricultural non-point source pollution has the following problems: First, it is impossible to prove whether the household survey

The technical specifications for agricultural non-point source pollution investigation require household surveys and on-site reporting to ensure the authenticity of the data, but filling in newspaper forms cannot reflect the above information; Paper-based forms cannot verify the indicators one by one, and often need to be detected in the data verification or audit stage, which affects the scientificity and authenticity of the data; third, the on-site investigation data needs to go through steps such as paper filling and computer input. The procedures are complicated and easily affect the authenticity of the data
