Wireless sensor network monitoring system for grain situation of grain depot

Abstract

The invention discloses a wireless sensor network monitoring system for the grain situation of a grain depot. The system comprises wireless sensor nodes, gateway nodes, a general packet radio service (GPRS) network, Internet and a monitoring center lower computer, wherein a group of wireless sensor nodes for acquiring grain situation parameters of the grain depot are connected with the GPRS network by a group of gateway nods; and the GPRS network is connected with the monitoring center lower computer by the Internet. The wireless sensor network monitoring system based on a ZigBee protocol can realize multi-parameter monitoring and monitor grain situation information such as temperature, humidity, grain moisture, mildew, insect pests and the like inside the grain depot in real time; and the GPRS network is connected with the Internet network, so the wireless sensor network monitoring system has low cost and high reliability, and is suitable for various grain storage depots.

Description

technical field [0001] The invention belongs to the field of grain depot management, in particular to a grain depot wireless sensor network monitoring system capable of monitoring multi-parameter grain conditions. Background technique [0002] At present, most of my country's grain situation monitoring systems adopt microcomputer monitoring, and the measurement method of signal transmission through cable network realizes fast, automatic and digital detection, and provides effective technical support for safe grain storage. So far, dozens of enterprises in China have produced grain situation monitoring and control system products, with various varieties and different system structures, but their basic functions are only 1-2 of the grain situation monitoring parameters. The most common ones are the temperature or humidity of the granary , that is, temperature and humidity monitoring inside and outside the granary, temperature monitoring and analysis inside the grain, ventilati...

Problems solved by technology

Although this monitoring method basically meets the requirements in terms of function, it will cause the following problems when wiring: the grain depot project is huge, resulting in high costs; once the equipment and wiring system are completed, it is difficult to change, and the flexibility of the system is poor, which is easy to cause The vacancy of its lines and collection facilities reduces the utilization rate of the system; the system is easily damaged by pests, food fumigation, human factors and other factors, resulting in secondary cost investment

The existing wired grain monitoring methods can no longer meet the requirements
