Description
(1), technical field: the present invention relates to a kind of Weighing method, particularly compensation Weighing method of a kind of cycle of electronic crane scale.
(2), background technology: at present, in the application scenario of weighing, the weighing apparatus that is fit to the use of crane suspender generally is electronic crane scale.According to the processing mode of weighing, existing electronic crane scale has following two kinds of forms usually:
One, static electronic crane scale: the electronic crane scale of this form stops behind lifting cargo usually, waits for and stablizes the artificial printing in back, storage or record the data of weighing, and then unload and hang.Though lifting and to unload the process of hanging be dynamic is in relative static conditions taking when weighing data, i.e. steady state (SS).
The electronic crane scale of this form is not installed the sensor that gyroscope and accelerometer etc. are measured scale body motion state in the scale body, do not consider the operating state of scale body when weighing computing.
The electronic crane scale of this form can only be in the applications that allows static weighing.Because need the crane suspender static stable in the weighing process, so operating efficiency is lower, the duty cycle of weighing is longer.Unload and hang the occasion that does not stop operation if be used in continuous lifting, then precision is lower.
The electronic crane scale that uses on the domestic and international market all is the static electronic crane scale of this form usually at present.
Two, Dynamic Electronic Crane Scale: the electronic crane scale of this form has installed the sensor of measuring scale body motion state usually additional on the basis of static electronic crane scale, consider the influence of scale body motion state in the algorithm of weighing.The use-pattern of the data of weighing is the same with static electronic crane scale, also is artificial printing, storage or record.
When using electronic crane scale to carry out the weighing of a batch of goods, normally earlier steelyard is suspended on the suspension hook, operation zero setting makes weight display return zero, whenever hangs the manual print record one hook weight of a hook goods then, with the weight addition of each time goods, draw the general assembly (TW) of this shipments at last again; When the weighing goods, show that sometimes data do not have back zero the zero point of electronic crane scale, also material can be bonded on the suspender sometimes, and the material of each bonding is more or less, is difficult to calculate, and these all can make electronic crane scale produce very big weighting error.
(3), summary of the invention:
The technical problem to be solved in the present invention is: at the prior art deficiency, provide a kind of weighing compensation Weighing method of cycle of electronic crane scale accurately and rapidly.
Technical scheme of the present invention:
Compensation Weighing method of a kind of cycle of electronic crane scale, adopt computing machine or microprocessor that actual value of weighing of electronic crane scale output is judged, handled, draw the net weight value of goods when at every turn weighing, then, the net weight value addition of each time goods is drawn the gross dry weight value of a batch of goods; The concrete operations step is as follows:
Step 1: the loading threshold value and the unloading threshold value that preestablish electronic crane scale;
Step 2: read actual value of weighing of electronic crane scale output, according to the actual value of weighing, loading threshold value and the residing state of unloading threshold decision electronic crane scale; If electronic crane scale is in stress state, then execution in step 3, otherwise execution in step 2;
Step 3: the actual value of weighing to electronic crane scale output is monitored, and waits until that the actual value stabilization of weighing after a scope, reads the actual value of weighing, the gross weight value that this actual value of weighing is weighed as this time;
Step 4: read actual value of weighing of electronic crane scale output, according to the state of the actual value of weighing, loading threshold value and unloading threshold decision electronic crane scale; If electronic crane scale is in unloaded state, then execution in step 5, otherwise execution in step 4;
Step 5: the actual value of weighing to electronic crane scale output is monitored, and waits until that the actual value stabilization of weighing after a scope, reads the actual value of weighing, the tare weight value that this actual value of weighing is weighed as this time;
Step 6: gross weight value and the tare weight value of will this time weighing are subtracted each other, and obtain the net weight value of this time goods, and the net weight value record of this time goods is preserved in corresponding storage unit;
Step 7: judge that computing machine or microprocessor are received and cease and desist order? if then execution in step 8; As not being that then execution in step 2, carry out weighing of goods next time;
Step 8: with the net weight value addition of each time goods, obtain the gross dry weight value of a batch of goods;
Step 9: finish.
Loading threshold value and unloading threshold value is the artificial rule of thumb gravimetric value of input.
Method according to the actual value of weighing, loading threshold value and the residing state of unloading threshold decision electronic crane scale is: when the actual value of weighing is higher than the loading threshold value, think that then steelyard is in stress state, when the value of the actual value of weighing during from stress state changes to when being lower than the unloading threshold value, think that then steelyard is in unloaded state downwards; The unloading threshold value is less than loading threshold value.
Beneficial effect of the present invention:
1, the present invention is divided into several independently metering cycles with the Weighing of a batch of goods, in each metering cycle, judge that according to actual value of weighing of electronic crane scale output the scale body is to be in the load or unload state, when stress state, obtain the gross weight of goods, when unloaded state, obtain the tare weight of goods, then gross weight value and tare weight value are subtracted each other, obtain the net weight value of every shipments, at last the net weight value addition of every shipments just can be obtained the net weight value of a batch of goods; The computing mode that this gross weight value of the present invention and tare weight value compensate each other can obtain goods net weight value accurately, and show whether totally whether data return zero-sum unloading (namely whether having material to be bonded on the suspender) zero point that need not consider electronic crane scale, the speed of not only weighing is fast, and the weighing precision height, weighing precision can reach OIML III level scale standard.
2, the cycle compensation is carried out in the present invention's each weighing of can be automatically the batch goods being worked continuously in the process, whenever the nt wt net weight that is hung, obtain a batch nt wt net weight by automatic accumulative total then, goods adds up the weighing precision height in batches, high efficiency, the manual printing of weighing under static state of need not stopping.
