Embodiment Construction

[0015] Such as figure 1 , 2 , 3, the present invention includes: several information collection modules, data wireless network transmission modules, remote receiving and monitoring platform modules. The information collection module is connected with the data wireless network transmission module through the communication cable, and the data wireless network transmission module and the remote receiving and monitoring platform module carry out signal transmission through wireless mode. The information collection module collects and processes the moisture information of each monitoring point, and transmits it to the data wireless network transmission module through the communication cable. The platform module receives, manages, publishes moisture information and controls monitoring points.

[0016] The information collection module includes: a soil moisture sensor, two temperature sensors, a groundwater level sensor, a signal transmitter, an analog / digital converter, and a micr...

Abstract

The system is composed of information collection modules, transmission module of data wireless network, remote receiving and monitoring and controlling platform module. Through communication cable, collection modules are connected to the transmission module. Signal transmission is carried out in wireless mode between the transmission module and platform module. Collecting and processing information of soil moisture at each monitored point, the collection module transfers collected and processed information to the transmission module through cable. The transmission module in wireless mode transmits information of soil moisture to the platform module. The platform module receives, manages and issues information of soil moisture, and controls monitored points. The invention realizes unmanned collection of information of farmland automatically in real time without limitation of space, time and number of monitored points.

Description

technical field [0001] The present invention relates to a system in the field of information processing technology for farmland management, specifically, a large-scale system based on GPRS / GSM / GPS (General Packet Radio Service / Global System for Mobile Communications / Global Positioning System) Farmland moisture remote monitoring system. Background technique [0002] Soil moisture is one of the most important and commonly used soil information. It is the basis for judging the profit and loss of soil moisture, making irrigation and fertilization decisions, and making drainage measures during the crop growth and development period. Have a good understanding and mastery of national water resources in the region. Therefore, accurate and rapid monitoring and forecasting of soil moisture is of great significance. For soil moisture monitoring, means and methods such as drying and weighing, neutron moisture meter, TDR time domain reflectometer and ground penetrating radar have been ...
