Embodiment

Present embodiment discloses the dispositions method of a kind of stationary monitoring and moving emergency system, be applied to the danger of rectangle industrial park Gas leaks.The monitoring range of monitoring device in having taken into full account monitoring system, and when wind direction changes, original portion Can the monitoring device of administration play optimal alarm function, present embodiment discloses the leakage of a kind of efficiently monitor hazardous gas the most economical Cost reaches minimum a kind of stationary monitoring monitoring harm gas diffusion and the Optimization deployment method of moving emergency system.

As it is shown in figure 1, the dispositions method that the solidification of the present embodiment is monitored with moving emergency system includes:

Step S10, the weight gas cloud plumage parameter leaked according to danger activating QI body and ambient parameter create and draw first in coordinate system Gas diffusion model:

The present embodiment is to assume that wind direction is the safety zone directly blowing to industrial park, and the interior dangerization of rectangle industrial park The warning concentration of gas leakage is c_a。

When wind direction is the safety zone directly blowing to industrial park, the first gas diffusion model is:

$C=\frac{b_0{h}_0{c}_0}{\mathrm{bh}}---\left(1\right)$

In conjunction with formula

$b=b_0{\{1+1.5{\left[\frac{{\mathrm{gh}}_0({\mathrm{\&rho;}}_0-{\mathrm{\&rho;}}_a)}{{\mathrm{\&rho;}}_a}\right]}^{\frac{1}{2}}\frac{x}{{\mathrm{vb}}_0}\}}^{\frac{2}{3}}---\left(2\right)$

And formula

$\frac{\mathrm{dh}}{\mathrm{dx}}=\frac{W_e}{v}---\left(3\right)$

Calculate and obtain.Wherein, b₀For at source of leaks, weight gas cloud plumage beam wind is to half-breadth, unit is rice；B attaches most importance to the beam wind of gas cloud plumage To half-breadth, unit is m；h₀For the height of weight gas cloud plumage at leakage source point, unit is m；ρ₀It is the initial density of heavily gas, single Position is kg/m³；ρ_aBeing atmospheric density, unit is kg/m³；V be weight gas cloud pinna rachis to rate of propagation, i.e. wind speed, unit m/s； X is wind direction and the axial distance of source of leaks under weight gas cloud plumage, and unit is m；c₀For the initial concentration of gas, unit is m/s；h The height of gas cloud of attaching most importance to plumage, unit is m；W_eBeing Air Entrainment coefficient, different air are involved in difference, and corresponding volume inhales coefficient also Different.Set up using source of leaks as initial point, wind direction as X-axis, weight gas cloud plumage beam wind to the coordinate system of half a width of Y-axis, as Shown in Fig. 2, the first gas diffusion model 1 is drawn in this coordinate system, and 100 represent rectangle industrial park.

For above-mentioned formula (1), (2) and (3), heavy gas cloud plumage parameter and the ambient parameter of danger activating QI body leakage are known.

Step S20, changes wind direction, and foundation also draws the second gas diffusion model in coordinate system:

In the present embodiment, changing wind direction is that wind direction rotates θ angle counterclockwise, calculates the second gas diffusion model.By public affairs Formula (1), (3) and equation below

$b^{*}\cos \mathrm{}\mathrm{\&theta;}-x\mathrm{}\sin \mathrm{}\mathrm{\&theta;}=b_0{\{1+1.5{\left[\frac{{\mathrm{gh}}_0({\mathrm{\&rho;}}_0-{\mathrm{\&rho;}}_a)}{{\mathrm{\&rho;}}_a}\right]}^{\frac{1}{2}}\frac{(x\mathrm{}\cos \mathrm{\&theta;}+b^{*}\sin \mathrm{}\mathrm{\&theta;})}{{\mathrm{vb}}_0}\}}^{\frac{2}{3}}---\left(4\right);$

$b^{**}\cos \mathrm{}\mathrm{\&theta;}-x\mathrm{}\sin \mathrm{}\mathrm{\&theta;}=-b_0{\{1+1.5{\left[\frac{{\mathrm{gh}}_0({\mathrm{\&rho;}}_0-{\mathrm{\&rho;}}_a)}{{\mathrm{\&rho;}}_a}\right]}^{\frac{1}{2}}\frac{(x\mathrm{}\cos \mathrm{\&theta;}+b^{**}\sin \mathrm{}\mathrm{\&theta;})}{{\mathrm{vb}}_0}\}}^{\frac{2}{3}}---\left(5\right);$

Calculate the second gas diffusion model, wherein, b^*Represent the positive axis of the heavy gas cloud plumage half-breadth of described second gas diffusion model；b^** Represent the negative semiaxis of the heavy gas cloud plumage half-breadth of described second gas diffusion model.

By the second gas diffusion model in coordinate system, the curve 2 in Fig. 2 is the second gas diffusion model.

Step S30, determine described first gas diffusion model and the described second gas diffusion model the first intersection point in addition to initial point with And public territory, and in described public territory, determine that the first line segment and gas concentration are warning concentration c_aWarning concentration point； Wherein, described first line segment is the line of initial point and described first intersection point；The gas concentration of described first intersection point is c₁:

From Fig. 2, it is not difficult to find out have two intersection points at the first gas diffusion model 1 and the second gas diffusion model 2: initial point O With the first intersection point A.Wherein, the first intersection point is by the most vertical equation group:

$b\mathrm{}\cos \mathrm{}\mathrm{\&theta;}-x\mathrm{}\sin \mathrm{}\mathrm{\&theta;}={-b}_0{\{1+1.5{\left[\frac{{\mathrm{gh}}_0({\mathrm{\&rho;}}_0-{\mathrm{\&rho;}}_a)}{{\mathrm{\&rho;}}_a}\right]}^{\frac{1}{2}}\frac{(x\mathrm{}\cos \mathrm{\&theta;}+b\mathrm{}\sin \mathrm{}\mathrm{\&theta;})}{{\mathrm{vb}}_0}\}}^{\frac{2}{3}}---\left(6\right)$

$b=b_0{\{1+1.5{\left[\frac{{\mathrm{gh}}_0({\mathrm{\&rho;}}_0-{\mathrm{\&rho;}}_a)}{{\mathrm{\&rho;}}_a}\right]}^{\frac{1}{2}}\frac{x}{{\mathrm{vb}}_0}\}}^{\frac{2}{3}}---\left(7\right)$ Calculate and obtain.

Solve above-mentioned equation group and i.e. can get removing of the first gas diffusion model 1 before and after wind vector and the second gas diffusion model 2 Coordinate (the x of the first intersection point A outside initial point O₁, b₁), by x₁Bring formula (1) into, and combine (2) and (3) and can calculate Obtain the gas diffusion concentration c of the first intersection point A₁。

Further, as in figure 2 it is shown, have a public territory 120 at the first gas diffusion model 1 and the second gas diffusion model 2, The first gas diffusion model 1 and overlapping region of the second gas diffusion model 2, i.e. by initial point O, the first intersection point A, first Gas diffusion model 1 part and a part of area defined of the second gas diffusion model 2.Far-end O and the first intersection point A Between line be the first line segment OA.

To report to the police concentration c_aBringing formula (1) into, and combine (2) and (3), can be calculated warning concentration is c_a? Coordinate (the x of warning concentration point B of public territory_a, b_a)。

Step S40, relatively gas concentration c of described first intersection point₁With described warning concentration c_a, according to described first intersection point, institute State warning concentration point and described first line segment determines the first monitoring node and the second monitoring node.

As it is shown on figure 3, this step S40 specifically includes following steps:

Step S43, determines that the second intersection point of described second vertical line and described first line segment, the abscissa of described second intersection point are x₀₁, the relatively abscissa x at described midpoint₀₀Abscissa x with described second intersection point₀₁:

If x₀₁>x₀₀, determine two intersection points of described first vertical line and the border of described public territory, and by two Intersection point is respectively as described first monitoring node and described second monitoring node；

If x₀₁<x₀₀, determine two intersection points of described second vertical line and the border of described public territory, and by two Intersection point is respectively as described first monitoring node and described second monitoring node.

Stationary monitoring the most according to claim 1 and the dispositions method of moving emergency system, it is characterised in that: described fixed test Also include with the dispositions method of moving emergency system: at described first monitoring node, described second monitoring node, multiple described 3rd monitoring node and multiple described 4th monitoring node are equipped with monitoring device.

Stationary monitoring the most according to claim 7 and the dispositions method of moving emergency system, it is characterised in that: described first is square The catercorner length of shape is the twice of the monitoring radius of described monitoring device.

Stationary monitoring the most according to claim 7 and the dispositions method of moving emergency system, it is characterised in that: described monitoring device For sensor.
