Novel portable soil moisture monitoring instrument based on GPS (Global Position System)/GPRS (General Packet Radio Service)/GSM (Global System for Mobile Communications)

Abstract

The invention discloses a novel portable soil moisture monitoring instrument based on a GPS (Global Position System) / GPRS (General Packet Radio Service) / GSM (Global System for Mobile Communications). The novel portable soil moisture monitoring instrument comprises an information acquisition module, a processing control module, a display module, a remote transmission module and a power module, wherein the information acquisition module is used for acquiring soil volumetric moisture content as well as longitude, latitude and time information; the processing control module is used for controlling collected soil moisture content and displaying and sending the collected soil moisture content; the display module is used for displaying soil moisture content data and the longitude, latitude and time information in real time; the remote transmission module comprises a GPRS / GSM module and a button selecting module and is used for sending the soil volumetric moisture content, longitude, latitude and time to a central station or mobile phone; and the power module is used for providing a plurality of paths of reliable direct current voltage. The novel portable soil moisture monitoring instrument integrates soil volumetric moisture content measurement, local display, remote transmission and geographical location and has the advantages of high measurement precision, multifunction and portability. The problem existing in the traditional soil moisture content monitoring is solved.

Description

Technical field: [0001] The invention relates to the technical field of soil moisture monitoring, in particular to remote, automatic and portable monitoring of soil volumetric water content and acquisition of information such as monitoring position and time. Background technique: [0002] Drought and flood disasters occur frequently in China's grain production bases, seriously restricting food security. Soil moisture content and farming characteristics have a great impact on the yield of crops. Therefore, it is necessary to obtain soil moisture in a timely and accurate manner during the annual spring and autumn planting seasons in order to arrange irrigation reasonably. The traditional method is to manually measure the soil moisture. Due to the large area of ​​cultivation, it not only consumes a lot of manpower and material resources, but also has poor timeliness, which often delays farming time. [0003] Soil water content is an important indicator of soil moisture. Th...

Problems solved by technology

[0006](1) The portable and wireless transmission of existing soil moisture measuring instruments cannot be combined. portable instruments;

[0007] (2) The measurement data is first saved in the memory or SD card, and after the measurement is completed, the data is imported into the computer for subsequent processing, which is not only prone to data loss, but also the measurement data cannot timely application;

[0008](3) Lack of automatic acquisition of auxiliary information such as measurement position and real-time time, the measurement position is manually recorded during measurement, and the measurement time is obtained manually or by the clock of the measuring instrument, which is easy cause data confusion and errors
