Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described further.

Seeing Fig. 1 and Fig. 2, this utility model includes some electronic tags and some reference modes, and some reference mode correspondences are received and dispatched The electronic tag of information, each reference mode connects long-distance communication network by corresponding gateway, and long-distance communication network is genuinely convinced in connecting Business device, central server connects long-range monitoring computer terminal and display screen, and electronic tag is as location node；

Described gateway uses ZigBee node, and ZigBee node includes data acquisition module and other modules being connected with general-purpose interface, General-purpose interface connects micro treatment module, and micro treatment module connects wireless communication module, general-purpose interface, micro treatment module and radio communication Module connects power module, and data acquisition module includes sensor and D/A converter module, and other modules include key-press module and LED Module, micro treatment module includes microcontroller and memorizer, wireless communication module include antenna for receiving electronic labeling information and For sending the ZigBee radio-frequency module of information, central server is connected with display screen by GPRS-DTU module, GPRS-DTU Module is all connected with central server and display screen by RS232.

Preferably, gateway is connected with telecommunications network by wire communication, and telecommunications network includes Ethernet, GPRS, CDMA In at least one.

Localization method of the present utility model comprises the following steps:

Step one, uses tunnel based on RSSI personnel positioning algorithm, and nodal distance d can be drawn by the formula 1 of wireless channel,

$P\left(d\right)=P\left(d_0\right)-10nlg\left(\frac{d}{d_0}\right)+\mathrm{\ξ}---\left(1\right)$

Wherein, P (d) refer to from transmitting terminal spacing be d time receiving terminal obtain RSSI value；P(d₀) refer to from transmitting terminal spacing be d₀Time connect The RSSI value that receiving end obtains；N represents path loss index, and its span is 2～5, it usually needs record at the scene；ξ refers to The speed that propagation loss increases with distance；

In engineering construction, our frequent wushu 1 is reduced to formula 2:

RSSI=A-10nlgd (2)

Wherein, A represents the RSSI value that when signal transmitting and receiving end spacing is 1m, receiving terminal obtains, and n is identical with the n in formula 1；

Step 2, gateway, RSSI value transmission to computer, then by calculating the coordinate positioning node, can be obtained by formula 2, ginseng The spacing examining node and location node is:

$d={10}^{\frac{A-RSSI}{10n}}---\left(3\right)$

Step 3, dependent variable y and independent variable x₁,x₂,L,x_mMeet following regression model:

$\left\{\begin{array}{c}y=a_0+a_1{x}_1+a_2{x}_2+L+a_m{x}_m+\mathrm{\ξ}\\ E\mathrm{\ξ}=0\end{array}\right.---\left(4\right)$

To dependent variable y and independent variable x₁,x₂,L,x_mBetween relation test, thus obtain s group data:

(x_i1,x_i2,L,x_im；y_i)；I=1,2, L, s

Step 4, can deduce linear regression coeffficient according to s group test data, multiple linear regression model formula 4 and s group test Data can get following formula:

$\left\{\begin{array}{c}{y}_1=a_0+a_1{x}_{11}+a_2{x}_{12}+L+a_m{x}_{1m}+{\mathrm{\ξ}}_1\\ y_2=a_0+a_1{x}_{21}+a_2{x}_{22}+L+a_m{x}_{2m}+{\mathrm{\ξ}}_2\\ LL\\ y_s=a_0+a_1{x}_{s1}+a_2{x}_{s2}+L+a_m{x}_{sm}+{\mathrm{\ξ}}_s\end{array}\right.---\left(5\right)$

In formula 5, ξ₁,ξ₂,L,ξ_sFor stochastic variable, being the residual error of each expression formula, the residual sum of squares (RSS) of this n time test can table It is shown as:

$R(a_0,a_1,L,a_m)=\underset{i}{\overset{s}{\Σ}}{(y_i-a_0-a_1{x}_{i1}-L-a_m{x}_{im})}^2---\left(6\right)$

In formula 6, R (a₀,a₁,L,a_m) fitting degree between this s group test data and regression function can be measured；

Step 5, seeks R (a₀,a₁,L,a_m) minimaThen have:

$\left\{\begin{array}{c}\frac{\∂R(a_0,a_1,L,a_m)}{\∂a_0}=0\\ \frac{\∂R(a_0,a_1,L,a_m)}{\∂a_1}=0\\ LL\\ \frac{\∂R(a_0,a_1,L,a_m)}{\∂a_m}=0\end{array}\right.---\left(7\right)$

For simplified style 7, the following matrix of definable:

$Y=\left[\begin{array}{c}{y}_1\\ y_2\\ M\\ y_s\end{array}\right],X=\left[\begin{array}{cccc}1& x_{11}& L& x_{1m}\\ 1& x_{21}& L& x_{2m}\\ M& M& & M\\ 1& x_{s1}& L& x_{sm}\end{array}\right],\mathrm{\β}=\left[\begin{array}{c}{a}_1\\ a_2\\ M\\ a_m\end{array}\right],e=\left[\begin{array}{c}{\mathrm{\ξ}}_1\\ {\mathrm{\ξ}}_2\\ M\\ {\mathrm{\ξ}}_s\end{array}\right]$

Then 5 formulas can be reduced to:

Y=X β+e (8)

Formula 6 can be reduced to:

R (β)=(Y-X β) ' (Y-X β)=Y ' Y-2Y ' X β+β ' X ' X β (9)

In formula 9, R (β) is to β derivation:

$\frac{\∂R\left(\mathrm{\β}\right)}{\∂\mathrm{\β}}=0---\left(10\right)$

Can be obtained by formula 9 and formula 10:

X ' X β=X ' Y (11)

When X ' X can the inverse time, formula 11 can obtain:

β=(X ' X)^-1X′Y (12)

β in formula 12 is regression coefficient, makes m=1, then can obtain:

$\mathrm{\β}=\left[\begin{array}{c}\frac{\stackrel{\‾}{y}(\Σx_i^2)-\stackrel{\‾}{x}(\Σx_i{y}_i)}{\Σ{(x_i-\stackrel{\‾}{x})}^2}\\ \frac{\Σ(x_i-\stackrel{\‾}{x})(y_i-\stackrel{\‾}{y})}{\Σ{(x_i-\stackrel{\‾}{x})}^2}\end{array}\right]---\left(13\right)$

Make y_i=RSSI_i,x_i=logd_i, i=1,2 ..., s, by calculated x_iValue and the RSSI of actual measurement_iValue brings formula 13 into, Obtain regression coefficient β；

Step 6, substitutes into A and n obtained in formula 2 and formula 3, and can try to achieve the distance of location node and reference mode, so This location node position in tunnel can be obtained afterwards by the algorithm of upper computer software.

With reference to Fig. 3, tunnel total length 1800m, it is divided into uplink and downlink.According to the feature of tunnel two-way simultaneous construction, by whole Bar tunnel is divided into four 900m regions, and the reference mode of system of the present utility model is linear distribution, in each region, every 20m disposes a reference mode, disposes a coordinator node every 100m, and electronic tag is randomly dispersed in has ZigBee In the tunnel of network.

Operation principle of the present utility model and work process be: the operating personnel's carrying electronic label in tunnel is constructed in tunnel, electricity Subtab can be received and sent messages, and the information that electronic tag is launched by reference mode passes to gateway (coordinator node), net after receiving Close (coordinator node) by wire communication mode the information of operating personnel is transferred to telecommunications network module (Ethernet, GPRS, CDMA etc.), telecommunications network module (Ethernet, GPRS, CDMA etc.) will be made by data communication interface The information of industry personnel is transferred to central server, and long-range monitoring computer terminal is connected with central server, so at long-range monitoring computer Terminal can check the position and dynamically of staff, and central server connects LED display by GPRS-DTU module, from And make the position of staff and Dynamic Announce on LED display.

Management personnel outside tunnel by long-range monitoring computer terminal can remotely recognize operating personnel in tunnel working condition and Position, decreases the situation of tunnel site inspection work, and management personnel reasonably can dispatch according to situation about remotely understanding, Avoid the situation of waste of human resource, when management personnel by long-range monitoring computer terminal find in tunnel dangerous time, can make Warning message is sent to operating personnel by long-range monitoring computer terminal, the region so that they avert danger, after accident occurs, pipe Reason personnel can actively develop according to the position of the operating personnel that computer terminal shows and rescue targetedly, thus improve rescue efficiency.

Tunnel based on ZigBee personal security alignment system can make management personnel can dynamically grasp operation in tunnel at any time The information such as the working condition of personnel and position, and can be the statistical analysis offer data foundation in later stage.

Method of the present utility model can carry out location tracking to the operating personnel in tunnel at any time, it is possible to accurately and in time by tunnel Interior regional personnel's situation dynamic reflection, to the long-range monitoring computer terminal outside hole, enables management personnel to grasp people in tunnel at any time The sum of member and distribution situation, in order to carry out more reasonably management and running.
