Abstract
The invention discloses an environmental monitoring system. A wireless digital sensor network is adopted by the environmental monitoring system. Within the range of the whole network, mutual communication is achieved between all wireless digital sensor modules, and wireless extension of the distance between every two adjacent network nodes can be achieved. The environmental monitoring system is quite convenient to use, low in cost and capable of solving the problems that in the prior art, cost is high, wiring and maintenance are difficult and damage to the environment is severely.
Description
Technical field
The present invention relates to Internet communication technology field, be specifically related to a kind of environmental monitoring system.
Background technology
Environmental monitoring is by the content to the mankind and the influential various materials of environment, the detection of discharge capacity, and the variation of tracking environmental quality, determines environmental quality level, for the work such as environmental management, pollution control provides basis and ensures.Briefly, understanding ambient level, carry out environmental monitoring, is the prerequisite of carrying out all environmental works.
Environmental monitoring generally includes background check, determines scheme, Optimizing, spot sampling, sample transport, experimental analysis, Data Collection, the process such as analysis integrated.Generally speaking, be exactly the process of the acquired information of plan-sampling-Analysis-synthesis.
Because China is vast in territory, all detect the environment of all protected locations, be that financial resources and manpower are all far from being enough.How to build a cost environmental monitoring system low, easy to maintenance and become the urgent topic of paying close attention to of people.
Past wilderness area is detected and was once adopted dedicated network and public network to carry out the long-distance transmissions of data, and wireless acquisition node below adopts 802 11 wireless networks such as grade to realize.The maintenance cost of each like this node is very high, and very inconvenient being difficult to popularized.
Summary of the invention
The present invention is directed to above problem a kind of environmental monitoring system is provided, this system adopts wireless digital sensor network, in whole network range, between each wireless digital sensor module, can intercom mutually, distance between each network node can wireless extensions, use very simple and convenient, with low cost, solved prior art cost high, be difficult to wiring and safeguard, to problems such as environmental disruption are large.
Object of the present invention reaches by the following technical programs:
A kind of environmental monitoring system, comprise multiple data acquisition nodes and a Centroid, Centroid intercoms by ZigBee-network mutually with multiple described data acquisition nodes, described multiple data acquisition node comprises data acquisition unit, Date Conversion Unit, storage control unit, wireless transmission unit, and described Centroid comprises radio receiving unit, host computer;
Ambient signal is passed to Date Conversion Unit by described data acquisition unit to carry out passing to storage control unit after signal conversion, storage control unit passes to wireless receiving module by the signal after conversion by communication unit, by wireless receiving module, the signal after conversion is passed to host computer through serial ports.
Described data acquisition unit comprises temperature signal collection unit, illumination signal gathering unit, sound signal collecting unit and moisture signal collecting unit.
Described control module is the CC2430 chip of TI company, and CC2430 chip is embedded with single-chip microcomputer core.
Also comprise that a single-chip microcomputer communicated by letter with storage control unit and further completed control function by serial ports.
The present invention compared with prior art, there is following advantage and beneficial effect:
The present invention adopts wireless digital sensor network, in whole network range, between each wireless digital sensor module, can intercom mutually, distance between each network node can wireless extensions, use very simple and convenient, with low cost, solved prior art cost high, be difficult to wiring and safeguard, to problems such as environmental disruption are large.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1

Ambient signal is passed to Date Conversion Unit by described data acquisition unit to carry out passing to storage control unit after signal conversion, storage control unit passes to wireless receiving module by the signal after conversion by communication unit, by wireless receiving module, the signal after conversion is passed to host computer through serial ports.
Whole system is made up of a Centroid and multiple back end, and multiple back end are all to communicate by letter with Centroid by wireless mode, and each node has relay function.If certain node is with center and Ei is mono-cannot communicate by letter apart from orchard time, can communicate by letter with Centroid by the relaying of other back end.
Described data acquisition unit comprises temperature signal collection unit, illumination signal gathering unit, sound signal collecting unit and moisture signal collecting unit.The voice signal that described sound signal collecting unit converts microphone is transferred to storage control unit by data conversion module.
Described control module is the CC2430 chip of TI company, and CC2430 chip is embedded with single-chip microcomputer core.This set can make most collecting works to add that outside data acquisition unit completes by CC2430.
Also comprise that a single-chip microcomputer communicated by letter with storage control unit and further completed control function by serial ports.
When real work, data acquisition node, at ordinary times in dormant state, is waken up rear ability image data is transmitted to Centroid, and completing after forwarding, enter low power consumpting state, and detects whether receive wake command, again enters dormant state if confiscate.
