Embodiment
Fig. 1 is the structural representation of mine car detection device first embodiment of identifying coals and gangues of the present invention and anti-cheating.As shown in Figure 1, the mine car detection device of this identifying coals and gangues and anti-cheating comprises LOAD CELLS 1, laser detector 2, camera 3 and controller 4.Wherein, LOAD CELLS 1 is arranged on the track, is used for that material that mine car is transported is carried out actual weight and detects; Be positioned at the laser detector 2 directly over the LOAD CELLS 1, be used to take place line laser, it is linear that this line laser is used to demarcate the top of material that mine car is transported; Be arranged at the camera 3 of rail side top, be used for gathering in real time the linear view data in top with laser detector 2 demarcation; The controller 4 that is connected with LOAD CELLS 1 with camera 3; Be used to receive the actual weight of the material that mine car is transported that LOAD CELLS 1 detects; The view data from camera 3 according to receiving is counted the mine car that goes, and calculates the standard weights of material that mine car is transported according to what receive from the view data of camera 3.
The measurement result that controller 4 returns according to value and the LOAD CELLS 1 of counting at every turn can be judged LOAD CELLS 1 and whether each mine car all carried out the detection of actual weight, thereby can prevent the contingent cheating that is directed against weighing platform.The standard weights that view data that the top of the description material that mine car is transported that controller 4 also can transmit according to camera 3 is linear and predefined standard coal equivalent ash density are calculated material that mine car is transported; Thereby the measurement result of the actual weight of returning according to standard weights and LOAD CELLS 1 is judged mine car and is transported the content of impurity in the material (mainly being spoil), thereby identification material that mine car is transported is the higher colm of coal, spoil or impurity content.
The mine car detection device of identifying coals and gangues that present embodiment provides and anti-cheating; Can, completion measure when measuring material that mine car is transported the impurity content of material that mine car is transported; Thereby realize the automatic identification to coal and spoil, the mine car detection device of this identifying coals and gangues and anti-cheating can also be accomplished the effective detection to the cheating of weighing that possibly exist simultaneously.
Fig. 2 is the structural representation of mine car detection device second embodiment of identifying coals and gangues of the present invention and anti-cheating.As shown in Figure 2; The mine car detection device of this identifying coals and gangues and anti-cheating comprises LOAD CELLS 1, laser detector 2, camera 3 and the controller 4 described in above-mentioned first embodiment; Wherein, LOAD CELLS 1 can be that weighing-rail formula or foundation ditch are platform-type, and above LOAD CELLS 1, standing has door shaped stent; A laser detector 2 is installed directly over the door shaped stent, and the oblique upper of support is installed the linear camera 3 in top that a collection laser detector 2 is demarcated.
In addition, acquisition control module 42 also is used for when the reception of view data is interrupted, and generates second trigger pip and transmission; Acquisition and recording module 41 also is used for sending all graph datas of record according to second trigger pip from acquisition control module 42; Then controller 4 can also comprise: linear statistical module 44, weight computing module 45, ash computing module 46 and judge module 47 relatively.Wherein, linear statistical module 44 is used to receive the graph data that acquisition and recording module 41 is sent, and it is linear to add up the standard top that draws material that mine car is transported; Weight computing module 45, it is linear to be used for adding up the standard top that draws according to linear statistical module 44, calculates the standard volume of material that mine car is transported, and standard volume and preset standard coal equivalent mass density are multiplied each other, and draws the said standard weights of material that mine car is transported; Ash computing module 46 is used for the actual coal ash part density according to standard weights, standard coal equivalent ash density and actual weight calculating material that mine car is transported; Relatively judge module 47 is used for actual coal ash part density is compared with standard coal equivalent ash density and preset colm ash density, judges that material that mine car is transported is coal or colm or spoil.
In addition, this controller 4 can also comprise: monitoring modular 48 and alarm 49.Wherein, monitoring modular 48 is used for according to count value and detected actual weight that the mine car that goes is counted, and whether monitoring has carried out the detection of actual weight to each mine car, when count value and actual weight not at once, the generation alarm signal; Alarm 49 is used for according to the alarm signal from monitoring modular 48 that receives, and triggers alarm 49 and reports to the police.
Particularly, when mine car passes through LOAD CELLS 1, LOAD CELLS 1 will be accomplished the accurate metering to mine car, record the actual weight of mine car.The accumulation shape of the material that mine car is transported of 2 pairs of processes of laser detector of installing directly over the door shaped stent simultaneously, scans; The CCD camera 3 of door shaped stent oblique upper is with the track while scan of recording laser detector 2, and promptly the top of material that mine car is transported is linear.The linear analyzing and processing of carrying out in the top of 4 pairs of solid accumulation shapes of controller; Confirm the height and the shape of solid accumulation; The standard coal equivalent mass density with standard coal that calculates thus under this piling height and shape is the standard weights of the material that this mine car is transported of reference; Utilize standard weights and actual weight to calculate the actual density proportion of material that this mine car is transported again, and then calculate the spoil amount that on average contains of material that this mine car is transported, thereby realize accurately defining of coal and spoil.
For example; The linear view data in top that 42 pairs of acquisition and recording modules of acquisition control module 41 receive is monitored in real time; Owing between mine car and mine car certain interval is arranged; When acquisition control module 42 monitors acquisition and recording module 41 at interval when not receiving the linear view data in top at certain hour; The mine car upright position, laser detector 2 place of having gone is described; This moment, these acquisition control module 42 triggering collection logging modles 41 were sent to linear statistical module 44 with all images data of record, carried out statistical computation by the top in the view data of 44 pairs of receptions of this linear statistical module is linear, can match draw triangle, top fan-shaped, trapezoidal or other regular shapes is linear; Thereby calculate the standard volume of material that mine car is transported by weight computing module 45, the approximate volume of this standard volume near actual material.Fig. 3 by mine car of the present invention the accumulation schematic cross-section of fortune material; As shown in Figure 3; The top that for example simulates is linear for curve, then mine car is divided into three parts, is calculated up and down the standard volume V of two the fan-shaped parts and the rectangular parallelepiped of centre respectively by weight computing module 45
1, V
2And V
3, when predefined standard coal equivalent mass density is P ' time, standard volume sum and P ' are multiplied each other, obtain standard weights W '=(V
1+ V
2+ V
3) * P '.The actual weight of the material that mine car is transported that LOAD CELLS 1 records is W, then
By ash computing module 46 according to formula:
Calculate actual coal ash part density of material that mine car is transported:
Again by judge module 47 relatively should actual coal ash part density P be attrital coal ash density P with standard coal equivalent ash density P ' with another preset ash density " comparing; if 0＜P≤P '; judge that then material that this mine car is transported is a coal, " as if P '＜P≤P, judge that then material that this mine car is transported is a colm; If P＞P ", judge that then material that this mine car is transported is a spoil.
