As shown in Figure 5, the industrial stock ground real-time positioning method for supervising based on the differential GPS technology provided by the invention, mainly follow following steps:
The first step, a point in the selection stock ground is as the relative three-dimensional coordinate initial point in stock ground, stacker-reclaimer movement station terminal gps antenna is placed this point, use station GPS receiver and antenna, demarcate stock ground longitude and latitude and the sea level elevation and the sea level elevation (S81) of three-dimensional coordinate initial point relatively.At first the reason that the geographic position in stock ground is demarcated is, the position data that differential GPS calculates is WGS-84 longitude and latitude and sea level elevation data, can not be directly used in the location, stock ground.Need be converted into local three-dimensional coordinate relatively.The local initial point of three-dimensional system of coordinate relatively then needs prior demarcation.Generally choose point on a certain corner, stock ground as initial point, the static demarcating function of use gps receiver obtains the longitude and latitude and the sea level elevation information of this point, as the local initial point (0 of three-dimensional system of coordinate relatively, 0,0), then after the longitude and latitude that receives of movement station terminal and base station terminal then be converted to local relative three-dimensional coordinate with the sea level elevation data according to this initial point.
Second step, use the raw material information and the stockpile distribution plan maintenance module of Surveillance center, by graphical editor or the form that imports from external data source, with stock ground raw material type data, and stockpile geographic distribution position data imports stock ground raw material information database, wherein, the true origin of stockpile geographic distribution position data is the relative three-dimensional coordinate initial point (S82) in stock ground in the step 1.The stockpile geographic distribution position data is here used local three-dimensional system of coordinate relatively, true origin is consistent with the true origin that the first step is demarcated, the relative position that its role is to guarantee stacker-reclaimer on the monitored picture and raw material stockpile is with actual consistent, makes that also analyzing alarm module can correctly judge the violation windrow and get then operation of gauge (stacker-reclaimer is whether at the enterprising windrow of the stockpile of mistake/get material).
The 3rd step, with the windrow of current production cycle and get the material operation and import heap and get then database of gauge, the windrow of described current production cycle and get the material working rule and comprise current production cycle regulation heap, the raw material type data of getting and the geographic distribution position data (S83) of its place stockpile.In this example, by raw material information and stockpile distribution plan maintenance module with the windrow of current production cycle and get the material working rule and import heap and get then database of gauge, as analyzing the foundation that alarm module is judged.Rule specifically comprises: in the current production cycle, need the raw material of stacking, the order of stacking, and position, the raw material that need take and the order of taking of permission to putting.
The 4th step, movement station terminal and base station terminal are accepted the gps satellite positioning signal, the movement station terminal intercoms mutually with base station terminal simultaneously, calculates the accurate longitude and latitude and the sea level elevation data of movement station terminal gps antenna position in the Difference Calculation mode, and is uploaded to Surveillance center (S84).In this example, stacker-reclaimer moves in the place, stock ground, and implement heap and get the material operation simultaneously, stacker-reclaimer movement station terminal and base station terminal are accepted the gps satellite positioning signal, the movement station terminal intercoms mutually with base station terminal simultaneously, calculate the accurate longitude and latitude and the sea level elevation data of movement station terminal gps antenna position in the Difference Calculation mode, and be uploaded to Surveillance center by the cable that connects base station terminal and Surveillance center's data communication module.According to gps receiver and radio station performance, data upload frequencies is 1/2nHz.Wherein n is the number of stacker-reclaimer movement station terminal.
In the 5th step, import the stacker-reclaimer operating state data in real time into and deposit stacker-reclaimer location and running state data storehouse (S85) in from external data source.Common stacker-reclaimer duty (switch/fault, windrow/get material) by the existing control system control in stock ground, these data can directly be inserted by control system, or site safety is required under the stricter situation, by inserting after the existing production information system transfer in stock ground.
The 6th step, Surveillance center receives the longitude and latitude and the sea level elevation data of station GPS antenna position, and, calculate the position and the attitude information of stacker-reclaimer and deposit stacker-reclaimer location and running state data storehouse (S86) in according to the relative three-dimensional coordinate initial point in the described this locality of step 1.In this example, at first definite local three-dimensional coordinate initial point (0,0,0) relatively according to step 1, the longitude and latitude of the movement station terminal gps antenna position that step 4 is obtained is local relative three-dimensional coordinate (x1 with the sea level elevation data reduction, y1 z1), (comprises stacker-reclaimer cantilever central point (43) position according to relative three-dimensional coordinate calculating stacker-reclaimer position, this locality and attitude data again, the stacker-reclaimer cantilever angle of pitch, to reclaimer cantilever rotation angle), algorithm following (, shown in Figure 8) as Fig. 7:
Known stacker-reclaimer (4) moves reciprocatingly on the fixing track (5) parallel with stockpile (6), piles, gets the raw material on the different stockpiles by rotation, pitching cantilever (41) simultaneously.
Local three-dimensional coordinate (the x1 relatively of known stacker-reclaimer station GPS antenna (32) position, y1, and track starting point (51) coordinate (x0, y0 z1),, 0), and known locations is put stacker-reclaimer cantilever rotation initial point distance L (jib-length), can try to achieve stacker-reclaimer angle of pitch α (1 formula), and further obtain cantilever at ground projected length H, thereby obtain rotation angle β (2,3 formula).
α＝arcsin(z
1/L)(1)
H＝cotα·z
1(2)
β＝arc?cotα·(y
1-y
0)(3)
Then, can try to achieve by formula (4) for stacker-reclaimer cantilever rotation initial point (43) coordinate (x2, y2,0) x2:
x
2＝x
1-H·cotβ(4)
And owing to stacker-reclaimer moves reciprocatingly along guide rail (5) all the time, then obvious:
y
2＝y
0(5)
So far, stacker-reclaimer cantilever rotation initial point (43) coordinate (x2, y2,0) with and cantilever angle of pitch α, cantilever rotation angle β calculates and finishes.
In the 7th step,, dynamically show by the form of the real-time monitoring display module of Surveillance center with three-dimensional picture with the step 6 result calculated; Analyze the running state data that alarm module reads current stacker-reclaimer, get the then current production cycle windrow in the database and get the material working rule and compare of gauge,, then report to the police automatically (S87) if be not inconsistent with heap.In this example, calculate the stacker-reclaimer position, the angle of pitch, rotation angle of gained display parameter according to step 6, real-time display module can be in real time be presented at the position and the attitude of stacker-reclaimer on the man-machine interface (71) as pre-stacker-reclaimer three-dimensional model in real-time monitoring display module.When Surveillance center constantly receives the stacker-reclaimer locator data, analyze alarm module (17) also the stacker-reclaimer running status is got with heap gauge then the rule in the database compare.Under nominal situation, during the stacker-reclaimer windrow, the raw material type of windrow must be in the windrow raw material type that rule base is permitted, but the position at bucket wheel place also must be within the windrow scope of rule predetermining; When stacker-reclaimer is got material, at first the stockpile of the position by the bucket wheel place is known current raw material type of taking, again by checking whether this kind raw material exists and get getting in the material kind list that gauge then allows, and current time takes this kind raw material, whether meets the material taking sequence of rule predetermining.If can not then send warning by above-mentioned detection, the operating personnel of prompting central control room, the accident that prevents takes place.
The present invention to reclaimer is positioned on the industrial stock ground, reaches the purpose of the stock ground operation being carried out Real Time Monitoring by Differential GPS Technology, has higher practicality, can effectively avoid because the accident such as wrong raw material of getting that the stacker-reclaimer positional fault causes. The present invention compares with the system that adopts other location technology, and it is low, non-maintaining to have a cost, and no cumulative errors are not subjected to the advantages such as weather, dust atmosphere affect substantially, are applicable to the bulk cargo stock ground of the multiple industries such as colliery, metallurgy, thermoelectricity.
