Description
Technical field
The present invention relates to warehouse monitoring technical field, particularly a kind of warehouse monitoring system based on signal condition.
Background technology
As economic develops rapidly, storage scale is increasing, and goods and materials species is also more and more.It is traditional based on people
The warehouse monitoring system led becomes very heavy, not only consumes wealth effort, is also easy to monitoring blind area occur.Just because of this, species
Various warehouse monitoring device is also arisen at the historic moment.In recent years, as technology of Internet of things is day by day favored by developer, based on thing
Therefore the embedded system of networking technology is also filled with fresh " blood " for warehouse monitoring system.
Wireless sensor network is a kind of distributed sensor, and its tip can be to perceive and check the external world
Sensor.Sensor in wireless sensor network wirelessly communicates, therefore network settings are flexibly, and device location can
To change at any time, the connection of wired or wireless way can also be carried out with the Internet, formed by communication
Individual multihop self-organizing network, can be widely used in industry, agricultural, medical treatment and daily life.
In industrial aspect, with expanding economy, the production of goods and materials is more and more, requirement of each manufacturing enterprise to warehouse
It is more and more.Warehouse is higher as a security requirement, the numerous industry of human attendance's demand, many with control point quantity
The dispersion of many, place, the complicated problem of site environment, this has become the major obstacle of line service.Wherein chemicals
Warehouse is at a relatively high for the requirement of safety and automatization.According to the incomplete investigation statisticses of storage association of China, whole nation danger in 2014
Change product storage area reaches 77,310,000 square metres, increased 5 .1% on year-on-year basis, but the chemicals warehouse area with rapid growth
Uncoordinated is but highlighting for chemicals warehouse safety issue.Be not good at due to storage environment, the original such as operated by personnel's error
Cause, chemicals warehouse accident on fire from explosion are common in news, such as common during Spring Festival fireworks and firecrackers warehouse blast, 2013
Guangzhou Baiyun District warehouse deflagration accident, PORT OF TIANJIN " 812 " explosion accident of 2015 etc., give people the people life security and
Property safety causes extreme loss, and very big impact is caused on corporate image and prestige.Therefore, it is necessary to design a kind of prison
Control system carries out early warning and monitoring to chemicals warehouse danger that may be present.
However, existing chemicals warehouse monitoring system, structure is single, substantially connects the side of each equipment using pipeline
Formula, transmission range are limited, and wiring is loaded down with trivial details, and extensibility is not enough, and transmission means is single, and practical function is bad, and cannot accomplish
The synchronous execution reported to the police and automatically control.Warehouse is the important place of storage, transfer and allotment material, and the storage condition in warehouse is straight
The quality for being related to material storing is connect, even loss of material can be caused when warehouse environment is severe, bring not to enterprise's production
Just, the detection of existing warehouse environment, especially humiture, using Hygrothermograph, needs personnel's number of degrees, it is impossible to intuitively show
Humiture numerical value, and warning cannot be sent when humiture parameter is exceeded in time, if personnel are not at the scene, it is difficult to recognize
The exceeded situation of humiture parameter, causes loss of material.Some are stacked with inside the bulk storage plant of combustible, and fire prevention is most critical
Job content, once have fire suffer from may destroy whole warehouse by fire, cause immeasurable loss.But some object storings are too
The various factors such as will ferment long produces fuel gas, once there are Mars or temperature too high, it is possible to there is fire, so inspection
The concentration for surveying fuel gas is very crucial work.
