摘 要现在的经济正在以惊人的速度发展着,人们的生活水平也有了质的飞跃,这也使得人们对饲料工业的发展越来越重视,而此工业的关键是配料这一部分,因此,饲料的配料控制系统的设计显得越来越重要。70402

首先,系统采用上位机与PLC组合的这种控制模式,通过详细地分析了该控制的两种方案,比较各自的优劣势。

然后,开始配料控制系统的硬件设计。采用6仓1秤1混合机的配料称重系统。本设计满足了中、小型饲料厂的需求,而且具有完善的功能并且完全合理。接着,进行了重要设备的型号的选择,还有上下位机通信的设计。

最后,进行了下位机的软件设计。对喂料、点动、秤门以及混合机门这几个模块进行软件设计,同时,在系统断电时,进行了恢复生产的设计。

饲料厂的生产效率有了很大的提升,工人的工作量明显减少,控制的精度更加完善,这些都是通过了有关的技术改造。本方案,在别的行业中配料控制起到了很好的指导作用。

Design of feed control system in feed mill

Abstract Now that the economy is at an amazing speed development, people's living standard has also been a qualitative leap, which also makes people pay more attention on feed industry development more and, while the industrial key is this part of the ingredients. Therefore, feed ingredients to control system design becomes more and more important.

First, the system uses the host computer and the PLC combination of this control mode, through the detailed analysis of the control of the two programs, compare their respective advantages and disadvantages.

Then, start batching control system hardware design. The batching and weighing system, which contains 6 positions 1 scale 1 mixer. This design meets the, the needs of small and medium-sized feed factory, but also has perfect function and is completely reasonable. Secondly the important equipment type selection and the communication between host computer and PLC design.

Finally, the lower computer software design. To feed, to move, scale and mixing machine door module of software design. At the same time, when the system is powered down, the resumption of production design.

Feed factory production efficiency has been greatly improved, significantly reduced the workload of workers, more perfect control precision, these are by the related technological transformation. The scheme, in other industry batching control to good guidance.

There are 18 figures, 2 tables and 22 references in this paper.

Key  words: PLC frequency converter  batching control system
