Soil temperature monitoring system for frozen earth area

Abstract

The invention discloses a soil temperature monitoring system for a frozen earth area. The soil temperature monitoring system comprises a plurality of temperature sensing buses embedded in the soil, a plurality of digital temperature sensors are packaged in the temperature sensing buses, the temperature sensing buses are connected with data acquirers arranged outside the soil, the data acquirers are connected with a data acquiring instrument arranged outside the soil through the wireless short-distance transmission technology, and data transmission is performed between the data acquiring instrument and a backstage data center via the wireless network. The soil temperature monitoring system has the advantages that the problem that data cables arranged underground are easy to break off is solved, influence on measuring accuracy from wiring is reduced, temperature convection between the sensors is prevented from influencing data accuracy, and frost heaving is prevented from damaging a temperature measuring system.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a soil temperature monitoring system in a permafrost region. Background technique [0002] Frozen soil refers to all kinds of soil with a temperature equal to or lower than zero degrees Celsius and containing ice. At present, the monitoring and research on the temperature of frozen soil mainly focus on the change of temperature in the frozen soil area. Data collection is carried out by means of pull wires, and the data is monitored by wireless transmission mode. This monitoring method is under the action of frozen soil disasters. The data acquisition cable is easily torn off in the frozen soil, and the monitoring equipment is easily pulled out in the frozen soil area. The weather resistance of the equipment and the accuracy of the temperature sensor are easily affected by the climate, resulting in incoherent data and even equipment failure. damage. [0003] Aim...
