Contaminated soil temperature and moisture gradient measuring system

Abstract

The invention discloses a contaminated soil temperature and moisture gradient measuring system. The system comprises Zigbee nodes corresponding to each soil detection point in a one-to-one mode and sensors which are arranged at the soil detection points and connected with corresponding Zigbee node interfaces. Each sensor comprises a sensor group formed by a soil temperature sensor and a soil moisture sensor. Each of the sensor groups is arranged in a vertical gradient direction of soil to be measured. Multiple sensor groups in the same vertical gradient direction are connected to a Zigbee gateway through a Zigbee communication channel, the Zigbee gateway is connected to a data service center through an Ethernet network, the data service center is connected to a user management client through the Ethernet network, and the user management client transmits processed data to a data display terminal to observe and analyze through an RS232 / RS485 communication interface. According to the invention, the measurement of three-dimensional soil temperature and moisture is achieved, each sensor node transmits data in a wireless mode, the energy consumption is low, and the application occasions are wide.

Description

technical field [0001] The invention relates to the field of contaminated soil remediation, in particular to a temperature and moisture gradient measurement system for contaminated soil. Background technique [0002] In recent years, the problem of soil pollution in my country has become increasingly prominent. For the treatment of polluted soil, it is of great significance to understand its temperature and moisture gradient parameters. Due to the complex geographical environment in my country and the uneven level of data observation in various regions, the data sources of soil temperature and moisture are relatively scarce, and data aggregation is difficult. The soil temperature and moisture data obtained by traditional measurement methods are far from meeting today's high-precision, networked, and intelligent measurement needs in terms of measurement accuracy, data collection volume, and reliability. At the same time, traditional soil temperature and moisture measuring in...

Due to the complex geographical environment of our country and the uneven data observation level in various regions, the data sources of soil temperature and moisture are relatively scarce, and the data aggregation is difficult

Soil temperature and moisture data obtained by traditional measurement methods are far from meeting today's high-precision, networked, and intelligent measurement needs in terms of measurement accuracy, data collection volume, and reliability.

At the same time, traditional soil temperature and moisture measuring instruments can only measure the temperature and moisture data of a single soil surface layer, and lack the complete, real-time, automatic and continuous measurement of soil temperature, Moisture Methods and Apparatus
