Method for carrying out wireless monitoring on barn

Abstract

The present invention discloses a method for carrying out wireless monitoring on a barn. The method comprises: communication link establishing; site signal detection; signal acquisition and processing; wireless remote transmission of the signal; information display, analysis and control command transmission; ultralimit parameter alarming; and site device control and management. According to the present invention, various grain parameters are collected by using the sensor nodes arranged in the barn and having different functions, the detected signal is real-timely transmitted to the control terminal through the GPRS module, the abnormal situation is predicted and alarmed, and the operation of the ventilation and grain protection equipment is automatically controlled according to the preset control policy, such that the grain security is ensured; and the method is simple, the use is easy, and the problems of high maintenance cost, poor system scalability and poor system mobility, poor interference resistance, easy transmission data losing and the like of the existing barn monitoring system are effectively solved.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a method for wirelessly monitoring a granary. Background technique [0002] Food is a necessity for human survival. Every year, a large amount of new grain is harvested and some old grain is backlogged. If a large amount of food is wasted due to improper storage, it will cause huge economic losses. Food security is very important. The safety of grain in the storage process is mainly manifested in the change of grain temperature and moisture. Once the grain is damp, its metabolism will speed up and produce respiratory heat. Changes, you can grasp the food situation. Therefore, the safe storage of grain has always been a major problem that plagues grain management units. It is imperative to improve the conditions of grain storage, improve the level of grain storage technology, and promote the progress of grain storage technology. The measures taken in the past were to dry the grain manually...

AI Technical Summary

Problems solved by technology

The measures taken in the past were to use artificial methods to dry the grain, ventilate it, and spray chemicals to prevent insect damage caused by improper storage, which consumed a lot of manpower and financial resources. However, the effect was not good, and the phenomenon of mold and deterioration still existed.

[0003] With the development of electronic technology and computer technology, electronics and computers are widely used to monitor and manage the grain situation, but there are still many unsatisfactory problems, such as high maintenance cost of wired access, poor system scalability and mobility, Poor anti-interference performance, easy loss of transmitted data, etc.
