一、引言混凝土集中生产中的多物种称量配料系统是整个生产工艺流程的关键部分,该部分采用电脑控制,对于提高生产效率和产品质量,有明显的效果。电脑配料过程简单说来就是:①对称量传感器的信号进行循回采样,并通过模数转换器变成数字信号;②通过标度变换,把读入的数学信号变成和各物种对应的重量值:③依据事先准备好,并存入一定内存区域的设定值,CPU进行判断,并按一定的控制方法,去控制执行机构,带动给
I. INTRODUCTION The multi-species weighing and dosing system in concentrated concrete production is a key part of the whole production process. This part is controlled by computer and has obvious effect on improving production efficiency and product quality. Computer ingredients process is simply to say: ① The signal of the weighing sensor is sent back to the sampling, and through the analog-digital converter into a digital signal; ② through the scale conversion, the read into the mathematical signal and the weight of each species Value: ③ According to the prepared in advance, and deposited into a certain memory area of the set value, CPU to determine, and according to certain control methods, to control the implementing agencies, to give
