Automatic Monitoring Device of Desertification in Northern Grassland

Abstract

The invention relates to an automatic northern grassland desertification monitoring device. The automatic northern grassland desertification monitoring device comprises a support and a data acquiring and sending terminal. The bottom end of the support is fixedly installed under the earth's surface, a solar cell panel, a lead storage battery, a horizontal support rod and the data acquiring and sending terminal are installed on the support, and the data acquiring and sending terminal and the storage battery are placed in an airtight waterproof box. An overground air temperature and humidity sensor, an overground CO2 sensor and an air velocity sensor are installed on the horizontal support rod. A total radiation amount sensor, an earth's surface air temperature and humidity sensor, an earth's surface CO2 sensor, an evaporation amount sensor and a rainfall capacity sensor tightly adhere to the earth's surface. A soil moisture temperature sensor is buried under the ground, the sensors and the data acquiring and sending terminal are powered by the lead storage battery, and signal lines of the sensors are connected with the data acquiring and sending terminal through lead wires in the support. The automatic northern grassland desertification monitoring device has the advantages of being simple in structure, convenient to operate and capable of adapting to a working environment of a northern grassland and achieving real-time and long-term measurement work.

Description

technical field [0001] The invention relates to an automatic monitoring device for desertification of the northern grassland, which is installed in the northern grassland area, uses sensors to collect and save the environmental parameters of the grassland in real time, and sends them to a server in a different place through a wireless mobile communication network (GPRS). The analysis and prediction of desertification provides basic theoretical data, and the environmental parameters measured by the device are accurate and comprehensive, which belongs to the field of environmental monitoring. Background technique [0002] The grassland resources in northern my country are the largest and most important land resources in the agricultural natural resources. Grassland resources are not only the material basis for the development of grassland animal husbandry, but also an important barrier to maintain ecological balance. In addition to the economic value of raising livestock to i...

Problems solved by technology

[0003] The existing grassland ecological environment monitoring devices have the following main problems: 1. Limited by the number of detection channels that the monitoring device can accommodate, the number of environmental parameters that can be measured is small, and at the same time, the arrangement of the sensor positions is random. The monitoring data cannot accurately assess grassland desertification; 2. The northern grasslands are characterized by cold winters and strong sandstorms in spring and autumn. Some sensors cannot work normally under these conditions and cannot be protected; 3. The core of the monitoring device is the data collection and sending terminal, which is responsible for the regular collection of sensor data and sends the collected data through the network. Due to the wear and aging of the sensor during use, the sensor needs to be calibrated regularly, and the existing The data collection and sending terminal lacks a sensor calibration module, making the collected data less and less accurate as time goes by

4. Since there is no power supply for the monitoring devices in grassland areas, solar energy is generally used for power supply. Reducing energy consumption and ensuring energy supply are the prerequisites for long-term automatic monitoring. The existing monitoring devices do not provide solutions for reducing the energy consumption of monitoring devices
