本发明涉及计量技术领域，具体是指一种用于计量机的自动获取计量预设值的方法。The present invention relates to the field of metering technology, and specifically to a method for automatically obtaining a metering preset value for a metering machine.
传统计量机同一计量组件在单次计量较大的场合下，往往需要进行大、小计量的配合使用，即粗计量和精计量的配合。大计量满足计量能力，小计量+落差实现计量精度。In the case of a single measurement component of a traditional measuring machine, the large and small measurements are often required for the same measurement component, that is, the combination of coarse measurement and fine measurement. The large measurement meets the measurement capability, and the small measurement + drop difference achieves the measurement accuracy.
而在此条件下，需要设定一个计量预设值，即“定量前”的值，当计量秤的称量值为计量总值-计量预设值时，计量模式将由大计量切换至小计量。Under this condition, it is necessary to set a measurement preset value, that is, the value “before quantification”. When the weighing value of the weighing scale is the total measurement value-the preset measurement value, the measurement mode will be switched from large measurement to small measurement .
目前市场上的计量机，一般为手动设置计量预设值。由于计量预设值设定的太大会影响计量能力，设定的太小会影响计量精度，因此手动设置时费时费力，有些调试不合理的还会影响计量精度或能力。Metering machines currently on the market generally set the metering presets manually. As the preset value of the measurement is set too large, it will affect the measurement ability, and the setting is too small will affect the measurement accuracy, so manual setting takes time and effort, and some unreasonable debugging will also affect the measurement accuracy or ability.

1+Q
2×t
2+Z＝W
1；
Q 1 × t 1 + Q 2 × t 2 + Z = W 1 ;
Q
1×t
1+Q
2×t
2’+Z＝W
2；
Q 1 × t 1 + Q 2 × t 2 '+ Z = W 2 ;
Q
1×t
1’+Q
2×t
2’+Z＝W
3；
Q 1 × t 1 '+ Q 2 × t 2 ' + Z = W 3 ;
其中，Z为落差值，W为实际称量值，Q

2为第二阶段计量时间的初次赋值，t
2’为第二阶段计量时间的再次赋值，上述三种赋值方式组成的三个方程为优选方式。
Among them, Z is the drop value and W is the actual weighing value. Q 1 and Q 2 are determined by the characteristics of the material itself and the mechanical structure. When the same or similar materials are measured, they are regarded as constant values, and t 1 is the first value. The first assignment of the measurement time in the first stage, t 1 ′ is the re-assignment of the measurement time in the first stage, t 2 is the initial assignment of the measurement time in the second stage, and t 2 ′ is the re-assignment of the measurement time in the second stage.

Q
1×t
1”+Q
2×t
2”+Z＝W
4；
Q 1 × t 1 ”+ Q 2 × t 2 ” + Z = W 4 ;
该方程与上述三个方程的任意两个均可组成新的赋值方式，同样可以达到获得落差值、第二阶段落料流量以及第一阶段落料流量的目的，因此只要改变两阶段的计量时间参数进行计量获得相应实际称量值，最低三次测定，即可形成三元一次方程组，从而获得所需要的落差值、第二阶段落料流量以及第一阶段落料流量。This equation and any two of the above three equations can form a new value assignment method, which can also achieve the purpose of obtaining the drop value, the second stage blanking flow rate and the first stage blanking flow rate, so as long as the measurement time in the two stages is changed The parameters are measured to obtain the corresponding actual weighing value, and the minimum three measurements can form a ternary equation system to obtain the required drop value, the second stage blanking flow rate and the first stage blanking flow rate.
所述的第二阶段计量时间的赋值为能够使所述的落差值保持不变的值，Z值在第二阶段计量时间/小计量时间/精计量时间足够大的情况下，也视为保持不变，所述的第二阶段计量时间的初次赋值确保在第二阶段计量/小计量稳定的情况下进行落差动作判定。The assignment of the measurement time in the second stage is a value that can keep the drop value unchanged. The Z value is also considered to be maintained when the measurement time in the second stage / small measurement time / fine measurement time is sufficiently large. Invariably, the initial assignment of the measurement time in the second stage ensures that the fall action determination is performed under the condition that the second stage measurement / small measurement is stable.
在进行实际计量时，根据计量预设值＝Q
2×t+Z获得实际计量预设值，t为第二阶段计量时间的实际设定值。由上述步骤可自动获得Q
2和Z值，在进行实际计量时，不应再人工计算，速度快，计算准确。
When performing actual measurement, the actual measurement preset value is obtained according to the measurement preset value = Q 2 × t + Z, where t is the actual set value of the measurement time in the second stage. The Q 2 and Z values can be obtained automatically from the above steps. In the actual measurement, it should not be calculated manually. The speed is fast and the calculation is accurate.
