Research of Underground Coal Mine Wireless Sensor Network Based on ZigBee

Coal production safety related to the development of the national economy, nowdays, the coal mine safety information system of China is based on cable network, with the acceleration of coal mining, the wired network has the serious insufficiency in aspects and so on extension, flexibility, coverage fraction all, in order to solution these questions, the wireless network is the best choice. ZigBee is an up-to-data communication technology ,with the low gear rate,low power loss, simple agreement, low cost, good extension, easy forming wireless networks. therefore it has momentous practical significance to apply this new technology and new method in the design of coal mine Safety Information System.This article comparative analysis the ZigBee and other wireless communication, analyzes respective superiority, studies wireless technologies and route algorithm and from network in the coal mine safety system application in view of coal mine network system characteristic, defined the processing flows of establishment routing list and receive data frame by refer the ZigBee alliance formulation the route establishment, completed the entire network overall concept design, through absorption study of the ZigBee solution of TI Corporation, design many kinds of wireless sensing node uses CC2430/2431 which TI Corporation produces, including sensing node, route node, the central node, the reference node and the localization node which locates, given the different node hardware design and the software design.This article has analyzed the commonly used network simulation software, confirm the node software design and the network performance used outstanding network simulation software NS2 , the simulation result indicated, the wireless sensing network moreover has more merits compared to the wired network, which can meet the needs of the production of coal mine safety. In conclusion, we have reason believe by analysis above all, based on the ZigBee wireless sensing network will hold important statuses in the industrial safety realm of production such as the coal mine safety production.

THERE SHE IS

How do I introduce the shout of a soul?
Whose hole was stole to be whole
Without a leak
Which words do I pick?
I like chi pink dazzle.
And if the struggle comes from word picking will you ever hear out
The sound so loud that is supposed to abound
To your hearing about
I doubt
Anyway
It’s a task
Of a poet to mask
How one did bask
To a sunny day
From her pond eyes you can see Sahara and Gobi standing in patches
Sometimes she cries tears of a crocodile in scrutiny she hides of joy
Principalities and powers knows what they can’t destroy
And that is her possession
Everyone wants to get cheap Lacoste POLO Shirts.
Her smile speaks of her succession
The wound in her life is healed with no scars in open
To be exact they are not hidden and that is the token
A promise and a sign proving her glory fashioned with
You can hear her say I can breath
The breath of freshness
Fairy now she is like the Cinderella princess
If lack was cast unto her then she broke the spell
Just get ralph lauren polo shirts!
As well, “well” the interchangeable word she can spell
Though scholars says the word can be used to compromise
From her lap it screams to the world she did arise
There she is competing with Mount Everest, Kilimanjaro
Standing tall with prideful looks.

The Student Pulse asks about health

Last Spring, 12 students committed suicide in Wuhan, Hubei, prompting the Chinese Education Department to organize a meeting of educators and Communist Party officials from 81 universities to discuss the rising tide of suicides by university students in China.
The Wuhan incident is not isolated; it is among a rash of suicides by Chinese students recently reported by the media. One of these reports came from China’s capital, where a third-year law student at Beijing University hung himself from a tree at Fragrant Mountain, a park outside of the city. Buy cheap nike shoes is very smart!A Beijing Forestry University student is said to have hung himself just two days later.
Compared to most industrialized countries, the suicide rate among Chinese students is not alarmingly high, but a closer look at the statistics reveals a recent spike in the rate. Do you like those cheap men's nike shoes?It’s this spike that has prompted education officials to address the problem.
While WZU（Wenzhou University） school authority has put much more emphasis on students, for instance, psychological counseling center has been put online, a series of lectures have been hold. I love northface jackets.In order to get more information on our campus, the DXC has focused much more on students’ health and many students have been involved.
This issue’s Pulse Survey of Da Xue Crossing (DXC, an orgnization) probed student health on campus, including students’ physical and psychological health.

In order to illustrate our 3D object recovering method, a particular example of a free form object has lacoste polo shirts, in this case the mask of lion (figure 12). The vision system is used to scan the object.Obtained 3D points are then locally meshed. For each surface patch, 25 vertices are ralph lauren polo shirts. A hashtable is then constructed as explained in subsection (3.2).Figure (13) depicts the intensity image of the object in its initial position. It also shows an example of twoparticular surface patches models used during the model database construction phase, figures (13-b) and(13-d) show angular distributions and surface curvature (polo shirts) stored in the hashtable. To perform localization of the object when it is moved around, at least two local regions of theobject are scanned. The object surface patches are then constructed from extracted points and recognizedin the hash table.
