Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Fig. 1 is the schematic flow sheet of the water conservancy construction field staff safety evaluation method of the embodiment of the present invention.As shown in Figure 1, the water conservancy construction field staff safety evaluation method of this embodiment, can comprise the following steps:
A. water conservancy construction scene is divided into n region.
Such as, whole water conservancy construction scene can be divided into factory building, road, tunnel, hillside, river valley etc. region.It should be noted that if there is discontinuous non-conterminous region of the same type, many places, such as, to there is many places factory building, can Further Division be also the first factory building region, the second factory building region etc., then 1,2 are numbered to all regions ... n.
B. corresponding geographical indicator D is set according to the geographical pattern feature in n region
1, D
2d
n.Wherein, D
1, D
2d
nbe positive number, subscript 1 to n represents the numbering of regional.Geographical pattern feature is more dangerous, and the numerical value of geographical indicator is larger.
It should be noted that, geographical indicator is constant.Such as, larger numerical value can be given to the geographical indicator in the more dangerous region such as steep hills slope, deep river valley, long and narrow tunnel, give less numerical value to smooth road, firm factory building etc. compared with the geographical indicator of safety zone.It should be noted that, geographical indicator is constant.
C. corresponding density index S is set according to the personnel's number in a current n region
1, S
2s
n, wherein, S
1, S
2s
nbe positive number, subscript 1 to n represents the numbering of regional.Personnel's number in region is more, and the numerical value of density index is larger.
It should be noted that, due to walking about of personnel, in the same area, personnel's number is in the same time not unfixed, and therefore density index is dynamic change.Such as, have 3 people in No. 1 region t1 moment, have 25 people in the t2 moment, the density index that therefore then the t1 moment in No. 1 region is corresponding should be less than the density index in t2 moment.Personnel's number in region is more, then easier interference mutually produces mistake, and it is also more difficult to occur that the personnel of potential safety hazard time domain inside withdraw, and therefore the numerical value of density index is larger.
D. arrange the dynamic effects factor according to other m dynamic effects factor respectively to the impact in n region, wherein, the dynamic effects factor of a jth dynamic effects factor to i-th region is designated as F
i,j, wherein 1≤i≤n, 1≤j≤m.Dynamic effects factor can comprise: weather, season, source of personnel etc.It should be noted that, because weather, season, source of personnel are all changing at any time, therefore the dynamic effects factor is also dynamic change.
Such as, when weather is continuous several days heavy rains, just have landslide risk, therefore will increase in the region hazard level near hillside, therefore weather effect factor should be set to bigger numerical (such as can be set to 1.5) to the hillside regional effect factor.Otherwise, when weather be continuous several days bright and sunny time, without the danger of landslide, therefore will reduce in the region hazard level near hillside, therefore weather effect factor should be set to comparatively fractional value (such as can be set to 0.8) to the hillside regional effect factor.Such as, when season is dry autumn, just there is mountain fire spontaneous combustion risk, therefore will increase in the region hazard level near hillside.Again such as, when source of personnel is the rural migrant worker from mountain area, owing to being familiar with mountain environment, then the region hazard level near hillside will reduce.
Normally, in order to the convenience understood and use, can this M*N the dynamic effects factor be write as form of look as shown in table 1.What deserves to be explained is, this table is Dynamic Maintenance, is not unalterable.

By product calculation, the impact of geographic entity factor, personnel's density factor and dynamic effects factor to be carried out comprehensive, the comprehensive safety index obtained has comprehensive and accurate advantage.
F. judge whether the comprehensive safety index in n region is greater than predetermined threshold value, if it is reports to the police.
It should be noted that, can also step G be performed while performing step F: the numerical value according to comprehensive safety index carries out classification, is place of safety, secondary place of safety, non-security district and explosive area by n territorial classification, and classification results is shown, such as, shown in Fig. 2.The display of visual pattern, effectively solves water conservancy construction field staff location and the technical requirement of safety management, and provides technical guarantee for safe construction.
In the water conservancy construction field staff safety evaluation method that the present invention proposes, upgrade a density index and the described dynamic effects factor at set intervals, then rejudge and evaluate the hazard level of regional, realize data and dynamically update in real time.
In sum, computer technology, mechanics of communication and engineering safety are combined closely by the water conservancy construction field staff safety evaluation method of the embodiment of the present invention, in a creative way the personnel positioning technology at water conservancy construction scene and data analysis technique are advanced to robotization, intelligentized control method stage, take into full account again water conservancy construction on-site actual situations simultaneously, there is the advantages such as automaticity is high, assessment result is accurate comprehensively, decision-making is timely.
