The f step: data handling procedure finishes.
See also shown in Figure 3, it is for the table top weighing principle sketch of invention tri-mesa electronic rail weigher system, like this to the further refinement implementation procedure of process flow diagram of the data handling procedure of tri-mesa electronic rail weigher system, because the train trailing or leading bogie is successively by a left side, in, right weighing unit 11,12,13, will produce test signal in case appear on the stage, it imports digital quantity into external device I/O port 41 in the embedded analytic system 4 through signal regulating panel 22 and A/D converter 23, enter processor 42 and at first image data is carried out train corresponding judgment and processing, if going up, train 8 do not claim, then image data is put into storer 44, otherwise the image data that will preserve before this averages processing as zero point, to the data Filtering Processing, remove undesired signal, judge to produce simultaneously and go up the weighting platform numbering that claims signal, whether train 8 goes up title can judge according to whether occurring skip signal in the image data, claim on the train 8 then that if occur the rising skip signal in the image data generation decline skip signal then train 8 is called in the following text.
See also shown in Figure 4ly, it obtains the process synoptic diagram of this section carriage weight for the present invention, and it step that comprises is:
The b1 step: weighing unit 12 column type sensors 121 are from producing the time T of signal to the blackout experience in the acquisition
0
The b2 step: obtain left weighing unit 11 column type sensors in 111 above-mentioned steps b1 time T 0 from producing signal to time T 1 that blackout experienced;
The b3 step: obtain right weighing unit 13 column type sensors 131 in above-mentioned steps b1 time T 0 from producing signal to time T 2 that blackout experienced;
B4 step: whether judge T1 more than or equal to T2,, then carry out following step b6 on the contrary if more than or equal to then carrying out following step b5;
The b5 step: left weighing unit 11 column type sensors, 111 detected weight and middle weighing unit 12 column type sensors 121 detected weight sums are carried out b7 as the weight in this section compartment;
The b6 step: right weighing unit 13 column type sensors, 131 detected weight and middle weighing unit 12 column type sensors 121 detected weight sums are carried out b7 as the weight in this section compartment;
The b7 step: this process finishes.
Notebook data processing procedure detailed annotation is: produce pressure with the column type sensor 121 of middle weighing unit 12 and begin the T during this period of time that disappears to the pressure signal that the column type sensor 121 of middle weighing unit 12 produces
0In, to about two weighing units sample continuously, left weighing unit 11 column type sensor 111 from it produces pressure signals and produces time that pressure signals disappear to left weighing unit 11 column type sensor 111 from it and longly be T
1, right weighing unit 13 column type sensor 131 from it produces pressure signal and is T to the time length that right weighing unit 13 column type sensor 131 from it produces the pressure signal disappearance
2, by comparing T
1With T
2Size judge type of train, just judge that according to the degree of overlapping size of train 8 bogies time period on three weighing units the trailing or leading bogie of train 8 is simultaneously at middle weighing unit 12, left weighing unit 11, still at middle weighing unit 12, right weighing unit 13, just can judge type of train thus, work as T
1Greater than T
2The time, this moment for according to train on corresponding weighing unit weight signal carry out filtering, the average then computing of deformation quantity summation that will in each sampling period, obtain, obtain bogie weight on each weighting platform, eliminate of the influence of factor such as temperature like this to weighing results, reduced column type sensor 111,121,131 and be subjected to measurement fluctuation that ectocine produces influence, thereby reduced error, worked as T measurement result
1Greater than T
2Time this moment, car weight was left weighing unit 11G
A left side is flatWith middle weighing unit 12G
In flatSum is worked as T
2Greater than T
1Time this moment, car weight was right weighing unit 13G
Right flatWith middle weighing unit 12G
In flatSum is this carriage weight just; With the weight addition in all compartments is the weight of whole train 8 just;
The method that obtains train speed is: because the sensor measurement length L of middle weighing unit 12 is known, pass through L/T
0Just can obtain the speed per hour of train 8 this moment;
The above only is preferred embodiment of the present invention, only is illustrative for the purpose of the present invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that claim of the present invention limited, revise, even equivalence, but all will fall within the scope of protection of the present invention.
