2. 工作原理 Theory
块状物料经过定量给料机的皮带拖动，物料的重力作用于荷重传感器上，荷重传感器将所受力的大小转为电信号输出至PLC的模拟量输入模块，同时电机旋转的速度也通过测速传感器输出至PLC的高速脉冲测量端口，PLC通过模数转换和高速脉冲测量将重量和速度的转化为数字量，经过运算处理得出当时的瞬时流量，并根据用户设定的给定量，计算二者差值，再经PID算法，输出控制值经模拟量输出模块转换成标准电信号去控制定量给料机的变频器，改变其转速，从而最终达到给定流量与瞬时流量跟踪的最佳控制效果。
The block material is transported by the belt of the weigher, the material act on the weighing sensor, the weighing sensor change the weight to electric signal and output it to the AI input module of PLC. At that time, the rotation velocity of motor is outputted to high speed pulse measure port of PLC by the velocity sensor, PLC changes the weight and velocity signal to numeral variable, via calculating, processing to get moment flow rate, and calculate the difference according to the setting from user, and then calculate the output at PID mode to output the control signal which is changed to standard electric signal by the AO module of PLC to control the inverter of the weigher, change the velocity, thus implement the moment flow rate closely follow the setting.

5.2. 调试commissioning
定量给料机正常使用前必须进行调试，调试按照以下步骤：
The machine has to be adjusted before using, the commissioning should be done according to the following steps:
5.2.1 通电检查check before power on

5.2.3 校零 tare
在皮带空载的情况时，调整传感器的压杆螺丝，给予传感器一定的预压力，通过控制仪的I/O监控功能观察重量采样值在3000左右即可。进入“校零”功能菜单，按“F1”键自动开始校零。校零时间开始倒计时，当时间会到0时，校零结束，控制仪自动计算出重量零点，在校零过程中，按“F2”键可中断校零. 进行校零操作时，螺旋计量称必须在运行状态
When no load on the belt, adjust the screw bolt act on the top of the sensor to make pre-pressure which the sampled value shown on in I/O monitor screen of the controller should be about 3000. Entering tare function menu, press F1 button to start the taring. The calibration timer begin to down time, when the time is 0, tare complete, the controller will auto calculate the weight zero, during taring, can press F2 button to interrupt the taring. Performing the taring, the screw weighing machine has to run.
5.2.4 标定calibration
校零结束后，进行标定，标定分为砝码标定和实物标定。
Tare finished, perform the calibration (weight or material calibration)
l 砝码标定：在定量给料机上通过标定杆挂上一定重量的砝码，进入挂码标定功能界面，按“F1”键控制仪自动启动定量给料机运行。等运转平稳后，按“F3”控制仪开始进行流量和累计量运算，同时标定时间开始计时，运转一段时间后可按“F4”停止流量和累计量运算。
Weight calibration: put weights that the weight is known on the calibration pole of the machine, come into weight calibration function screen, the controller will auto start the machine running by pressing the F1 button. After running is stable, by pressing the F3 button the controller will begin to calculate the flow rate and amount, simultaneity the calibration timer begins to time, after run for a period of time, the calculation of flow rate and amount can be stopped by pressing F4 button.
⑴ 等定量给料机运行稳定后，测量皮带运行一周时间，计算出当前的实际流量：
When the running of machine is stable, measure the belt running time for a cycle, then calculate the current real flow rate:
I1＝G×L÷T÷L0 （Kg/s）
其中G：含标定杆在内的砝码总重量（Kg）；
L：皮带周长（m）；
T：皮带运行一周时间（s）；
L0：定量给料机有效的称量段（m）。
G: the weight both calibration pole and the weights (Kg)
L: the girth of belt (m)
T: belt running time for a cycle
L0: effective weighing segment of the machine
⑵通过控制显示累计量除以标定所用的时间计算出显示的平均流量I2，计算误差：
By controlling the indicated average flow rate (I2) that can be calculated by using the time used for calibration divide the indicated amount, the deviation can be got.
Δ＝（I1－I2）÷I1×100%
若|Δ|符合精度要求，标定结束，否则修正流量系数：
If Δ meet the requirement of precision, the calibration finish, otherwise need to correct flowrate coefficient.
新流量系数＝(I1÷I2) ×原流量系数,将新流量系数替换原流量系数，重复上述⑴～⑵步骤。
New flow rate coefficient = (I1÷I2) × old flow rate coefficient, then replace the old flow rate coefficient with new flow rate coefficient, do the calibration again according to above steps.
标定结束，按“F2”停止定量给料机的运行。
Calibration finish, press F2 button to stop the machine.
l 实物标定：实物标定是称量经过定量给料机计量的物料的实际重量与控制仪所显示的累计重量进行比较，来验证定量给料机的计量准确性的标定方法，并根据偏差修正流量系数。
Material calibration: the calibration is to compare the real weight of material via the machine and displayed one by the controller to correct the flowrate coefficient according to the got difference. This is used to verify the measuring veracity of the weigher system.
在实物标定开始前，现场必须准备好接物料的工具、称量物料的称等，现场打扫干净，准备工作结束之后启动定量给料机开始下料，在现场同时接料，下料过程中屏幕显示当前的瞬时流量、重量、速度、累计量等实时数据，等累计到一定重量时停止下料，现场开始称量所接的物料的重量得出实际重量值Z1，根据控制仪显示的累计重量值Z2计算误差：
The balance for weighing material and the relative tools for storing the material should be prepared before starting material calibration, the spot should be cleaned, then start the conveyor to transport material, at that time encase the material to tool, the screen will indicate the data of current moment flowrate, weight, velocity, amount etc., Waiting for weight of material reaches expected value to stop material transportation, then weigh the collected material to get the real value of weight (Z1), then calculate the error according to the indicated weight amount (Z2).
Δ＝（Z1－Z2）÷Z1×100%
若|Δ|符合精度要求，标定结束，否则修正流量系数：
If Δ meet the requirement of precision, the calibration finish, otherwise need to correct flowrate coefficient.
新流量系数＝(I1÷I2) ×原流量系数,将新流量系数替换原流量系数，重新再做一遍实物标定，直到误差达到要求。
New flow rate coefficient = (I1÷I2) × old flow rate coefficient, then replace the old flow rate coefficient with new flow rate coefficient, then redo the material calibration until the deviation meet the requirement.
进行实物标定时要注意：开始下料后现场接料时必须将所下的物料全部接好，不能漏，下料时尽可能多下些料，让系统稳定运行时间比较长一点，这样可减少启动停止时的波动。在称量实际物料时要细致，最大限度地减少人为误差。
Notice for calibrating: all material should be collected after starting, should not be leakage, it is expect to get more material and longer running time, this can reduce wave motion of material. Should be carefully during performing calibration for avoiding make deviation by operator.
在挂码标定和实物标定中，按“F5”键对累计和标定时间清零。
Pressing F5 button can reset the amount and calibration time during calibration.
