Problems solved by technology

Although the functions can basically meet the requirements, most of the systems still use wired methods. The entire measurement and control network is very cumbersome to lay, and the network structure is not very flexible, resulting in very poor scalability. There are many deficiencies and needs improvement

Embodiment Construction

[0028] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] As shown in Figure 1, the composition of the system of the present invention comprises 4 kinds of nodes and 1 server, and the title and the function of various equipment are as follows:

[0030] (1) Sensor node A. According to a certain rule, it is densely distributed inside the grain, responsible for collecting grain parameters, such as temperature, humidity and moisture, and routing the data to the coordinating node of the granary.

[0031] (2) Coordinating node B. Each granary is equipped with a coordination node, which is mainly used to complete the active execution function of the measurement and control system: control the operation of ventilation and cooling equipment according to the analysis results sent back by the server. In addition, it is also responsible for collecting the data collected by all sensor nodes in th...

Abstract

A grain-state detecting system based on wireless sensor network relates to the application of wireless network, and several sensor nodes are berried in the granary to form the cubic monitor network; coordinating node is mounted in every granary, located in outer of granary; at least one relay network consisting of relay nodes is designed according to the granary, and the position of relay nodes are fixed; information sink node and terminal sever are configured separately, located in control room; the coordinating nodes gather the information collected by several sensor nodes, and send it to the terminal sever by the relay network and information node consisting of relay nodes, the software in terminal sever processes the information, and sends commands to coordinating node to realize the network management for granary. The invention makes the detection automation develop fatherly, and improves the management level of information, and it is significant for science and grain security.

Description

technical field [0001] The invention relates to the field of wireless network application technology, in particular to a grain situation measurement and control system based on a wireless sensor network for grain storage. Background technique [0002] As the saying goes: "Food is the most important thing for the people." Even in today's high-tech development, people's survival is inseparable from food, which is related to the development of society and the stability of people's lives. However, when the moisture is high and the temperature is high, the grain will become moldy in more than 10 days. If it is not treated in time, the grain will be moldy and deteriorate. Moldy grains, grains that have changed their taste, and seed grains that do not germinate will lose their original use value and cause serious economic losses. Therefore, grain storage work has become very important. During the storage of grain, changes in grain conditions (temperature, humidity, moisture, pest...
