Description

A kind of running scale method for processing weighing data based on travelling facility operating status

Technical field

The invention belongs to running scale weighing technology fields, and in particular to a kind of running scale based on travelling facility operating status Method for processing weighing data.

Background technology

Traditional platform scale formula and axle weight scale formula running scale only show weighing data with general weighing instrument, it is impossible to independent to realize When driving main hook promotes and land same weight, running scale weighing data is consistent, is not avoided that and collects incorrect state of weighing Weighing data, platform scale formula and axle weight scale formula running scale are weighed object weight and are carried by two parts：A part is by running scale Weighing sensor carries；Another part is carried by reel steel wire ropes, and this part following vehicle main hook promoted and the direction of landing and Change, the carrying of running scale weighing sensor is caused also to change in the opposite direction therewith so that be weighed the weighing data of object This does not answer following vehicle main hook traffic direction to change and change.Traditional common weighing instrument is weighed object status signal and is not involved in exporting The control of data also without the same equivalency transform formula for being weighed weighing data between object different conditions, can't resolve and weigh The problem of data are with the variation of object operating status is weighed, and traditional common weighing instrument is without the work(of the correct state of weighing of detection Can, collected weighing data is unreliable.

Invention content

In order to compensate for the shortcomings of the prior art, the present invention provides a kind of running scales based on travelling facility operating status to claim Weight data processing method.

The present invention is achieved through the following technical solutions：

A kind of running scale method for processing weighing data based on travelling facility operating status, includes the following steps：

It is general in running scale including big trolley, major-minor hook position, the range etc. for being weighed object 1. simulated driving scale use state Verification running scale promotes state in weighing instrument；

2. deriving the general weighing instrument of running scale after landing stops shows weighing data W_{Drop is aobvious}Equivalency transform is promotes show value W_{It rises aobvious} Formula:

If suspended object landing stops after stablizing, the general weighing instrument show value W of running scale_{Drop is aobvious}Corresponding promotion show value W_{It rises aobvious}, then： W_{Drop is aobvious}-W_{It rises aobvious}=δ=δ_{Lower limit}+K(W_{It rises aobvious}- W_{Lower limit}), W_{It rises aobvious}= W_{Drop is aobvious}/(1+K)-δ_{Lower limit}/(1+K)+ KW_{Lower limit}/(1+K)

Wherein：Section deviation variation rate when K is landing, K=（δ_{The upper limit}-δ_{Lower limit}）/ (W_{The upper limit}-W_{Lower limit})；δ_{The upper limit}、δ_{Lower limit}Area during for landing Between bound W_{The upper limit}、W_{Lower limit}Corresponding show value deviation；

3. after recording running scale landing stopping, section bound and its corresponding show value deviation are calibrated, and determine therefrom that title Tuple is according to the undetermined coefficient in equivalency transform formula：1/ (1+K), δ_{Lower limit}/ (1+K), KW_{Lower limit}/(1+K)；

4. by programs and the driving such as the weighing data equivalency transform formula of determining undetermined coefficient and weighing data export-restriction condition The hardware signals such as big trolley, the hook-shaped state of major-minor, position signal are input in driving programmable controller, and it is general to connect running scale Weighing instrument and driving programmable controller communication interface；

5. normally weigh, original or newly-increased programmable controller of driving a vehicle is according to weighing data export-restriction condition and equivalency transform Formula exports correct weighing data signal, and is transmitted in wireless transmitting device and display.

The beneficial effects of the invention are as follows：1. outside traditional common weighing instrument, by adding the correct state of weighing of detection Hardware and software, solve the problems, such as it is same be weighed object weighing data not be weighed object operating status variation；

The function of state 2. traditional common weighing instrument is correctly weighed without detection, collected weighing data is unreliable, this hair The bright software and hardware by adding the correct state of weighing of detection filters out wrong data, solves the problems, such as that weighing data is unreliable.

In attached drawing 2, symbol meaning：

F_js：Reel steel wire ropes are by reel pulling force, F_ds：Movable pulley steel wire rope is by fixed pulley pulling force, F_dm：Movable pulley is to steel wire rope Stiction, n：The radical for the steel wire rope being connect on movable pulley with fixed pulley, in each n/2 piece in movable pulley both sides, W_w：Sling object Weight, W_z：The sum of scale dead weight.

It slings object and is promoted and stop instantaneous quarter, point of contact coiling steel wire rope has the tendency that moving upwards on the left of movable pulley, reel Pulling force is with point of contact coiling steel wire rope by the peace of the pulling force of fixed pulley under point of contact on the right side of downward stiction and movable pulley Weighing apparatus.

F_js=F_ds+F_dm... ... ... reel steel wire ropes stress balance formula

W_w+W_z=F_js+nF_ds... weighing sensor exports nF_dsRelational expression with slinging object weight

=nF_ds+F_dm+F_ds= F_ds（n+1）+F_dm

nF_ds=（W_w+W_z-F_dm）n/（n+1）…………………………①

It slings the object landing stop timing, steel wire rope has the tendency that moving upwards on point of contact on the right side of movable pulley, and fixed pulley is to steel wire rope Pulling force is with steel wire rope on point of contact by flat by the sum of roller steel wire rope tension under point of contact on the left of downward stiction and movable pulley Weighing apparatus.

F_ds= F_js+F_dm... ... ... ... ... fixed pulley steel wire rope force balance type

W_w+W_z=F_js+nF_ds=F_ds-F_dm+nF_ds=（n+1）F_ds-F_dm

F_ds=（W_w+W_z+F_dm）/（n+1）

nF_ds=（W_w+W_z+F_dm）n/（n+1）…………………………②

2. the F of formula that formula subtracts 1=2_dmn/（n+1）, i.e., same to sling object, running scale weighing sensor output signal value fall ratio is promoted High 2 F_dmn/（n+1）.

In view of same object of slinging is promoted and landed（Operating status changes）When, running scale weighing sensor stress is different, leads to The data that both direction cannot be taken into account simultaneously with weighing instrument are accurate, can only verify the accuracy in promotion or a direction of landing. Therefore, it is necessary to which the display data of running scale other direction is sent to other places to carry out conversion process together with status signal, Can make it is same sling object promoted with landing show value it is consistent.

The present invention is not limited to the above-described embodiments, anyone should learn the present invention enlightenment under make with the present invention With same or similar technical solution, each fall within protection scope of the present invention.

The present invention be not described in detail technology, shape, construction part be known technology.
