Description
Technical field
The invention belongs to radio communication and internet of things field, it is related to a kind of greenhouse corps environment of ZigBee technology
Information wireless networking monitoring system.
Background technology
Greenhouse is that one kind can change plant growth environment, optimum condition is created for plant growth, extraneous four season crack is avoided
Change the place influenceed with harsh weather on it, greenhouse builds frame structure and is used as all or part of structure from daylighting covering material
Material, can be not suitable for the season cultivated plant of plant growth, be used for the plants such as low temperature season warm season vegetable, fruit, flowers
The function such as cultivation or nursery.Hothouse production can reach regulation term, enhancing development, preventing and treating pest and disease damage and raising quality, production
The purpose of amount.With continuing to develop that polyhouse-based agriculture is produced, although the polyhouse-based agriculture mode of production is just slowly turned to based on the manpower
Based on mechanical work, but at present, most of growers still continue to use artificial method on duty to keep an eye on greenhouse, and manpower and materials are big
Amount is wasted, and Temperature and Humidity Control is unsatisfactory, often because Temperature and Humidity Control it is improper cause crop production reduction so as to bring through
Ji loss.In addition, the acquisition of the better greenhouse corps growing environment information of hardware facility typically by manual record and divides
Analysis, then manually enters computer, is handled by corresponding software, stores data into database, the live cloth of this mode
Line is wired mode communication, and installing maintenance makes troubles, while also increasing cost of human resources proportion.
China's polyhouse-based agriculture control technology introduce with progressively grow up in self development process, but most of also in
Single controller+this state of single-sensor+executing agency.Generally speaking also in from simple application to it is practical and it is comprehensive should
With the stage of transition.Many sensings communicated using wired mode are monitored and controlled for information in certain area and equipment
Device, network is in wiring and maintenance process because circuit corrodes and damage causes network interruption, the production estimation band to greenhouse
To influence.Other system configuration has that Node distribution is uneven, quantity is on the low side, data acquisition is inaccurate, node reliability is not high asks
Topic, it is difficult to provide in real time, accurately quantify status information, mainly manually experience passively realizes insulation, cooling, sunshade
And rain-proof, and temperature, light, water, fertilizer can not be adjusted on one's own initiative, this is almost into the major obstacle of limitation greenhouse crops good quality and high output.
Recently as developing rapidly for electronic information technology, information-based change is brought with administrative skill to polyhouse-based agriculture monitoring
Leather, " industrialized agriculture ", " precision agriculture ", " wisdom agricultural " concept are arisen at the historic moment.Computer control and management system is continuous
Absorption automatically controls the theory and method new with field of information management, plants feature with reference to greenhouse corps, constantly brings forth new ideas, progressively
It is perfect, so that greenhouse gardening industry realizes modernization, industrialization truly.
Based on this, design and complete a set of for greenhouse corps environmental information multiple terminals wireless self-networking monitoring system,
Using ZigBee technology, fusion Internet of Things and embedded Control technology realize terminal node to greenhouse corps growth information
Real-time collection, monitoring, greenhouse peasant household can understand crop growth situation in greenhouse in real time, according to crops air and soil
The situation of change of the parameters such as humiture carries out dynamic regulation.System using ZigBee chips CC2530 build terminal acquisition node,
Routing node and telegon aggregation node.Terminal acquisition node periodicity gathered data is reported to by multihop routing and telegon
PC monitoring clients and greenhouse peasant household mobile phone terminal.Between monitoring system node can self-organizing build network, even if nodes break down,
Network can self-regeneration, system worked well, networking communication protocol is simple and reliable, and sensor node has that sensitivity is high, survey
Amount is accurate, low in energy consumption, wireless aware, autonomous networking, inserting knot flexibly, it is repeatable the advantages of utilize, with larger market
Competitiveness and wide application prospect.
