Granary grain status monitoring system based on wireless sensing network

Abstract

The invention discloses a granary grain status monitoring system based on a wireless sensing network. The granary grain status monitoring system comprises the following steps of: set-up of temperature and humidity collecting data of a granary: collecting temperature and humidity data of the granary by low-power temperature and humidity collecting modules, transmitting data information to a single-chip microcomputer, storing and processing the received data information by the single-chip microcomputer and then transmitting the processed data information to a transfer network node station by a wireless module; deployment of the transfer network node station: separating the wireless reception of the data on a collecting end and the wireless transmission of the data to a receiving end by two controllers so as to solve the problems of huge transfer data quantity and reduced wireless transmission speed, integrating the data information transmitted by a plurality of collecting modules and rapidly transmitting the integrated data information to a wireless data terminal; and detection of a wireless receiving terminal: forming the wireless receiving terminal by a PC (Personal Computer) machine or a mobile terminal device, a wireless transmitting and receiving module and a communication circuit. According to the granary grain status monitoring system disclosed by the invention, effective control over free access to grain status detection information through the embedded mobile terminal or a desktop in a multi-mode manner is realized, and the efficiency for conveniently and rapidly controlling the actual information of the grain status of the granary is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor network granary monitoring system, in particular to the monitoring system for granary temperature and humidity collection data on PC or mobile terminal by using embedded platform architecture wireless network, and can realize the dynamic display of monitoring data , management, distribution and control. Background technique [0002] At present, in grain storage, in order to improve the grain storage environment in time and improve the quality of grain storage, it is essential to establish a perfect reserve adjustment system. Since the 1970s, electronic technology has been used to detect grain temperature in the grain storage environment. At the beginning, copper resistors and thermistors were used as temperature sensors. With the development of electronic device manufacturing technology, a numerical control grain temperature inspection system appeared. Since the 1980s, the emergen...
