基于 PLC 自动运料小车设计

来之后，得到了非常广泛应用。并且由于应用领域及用途不断扩大，PLC 自身也

在这种情势发展迅猛。致使 PLC 在制作成本持续下降前提下，保持着提高集成度、

缩小体积、加大自身容量、提高运营速度、以便使用和综合性能加强发展趋势。

当前由于 PLC 具备价格低廉、可靠性高、合用性强、使用简朴灵活、维护和修改

以便等长处，在世界范畴内各个行业领域得到了广泛应用。

由于国内制造业迅猛发展，老式人工运送生产材料方式已成为提高生产力桎

梏，而本设计中将运料小车这一重要生产工具由手动变为自动化，在大大提高生

产效率同步，还解放了劳动力、保障了生产安全、减少了生产对于环境规定，并

在一定限度上提高了生产自动化限度。

本设计以 PLC 历史和运料小车现状为切入点，详细讲述了用 PLC 来控制运

equipment proposed ，reliable ，universal ，variable ，easy to repair and came into

being . Therefore ，after the PLC is designed manufactured ，has been very widely

used. And because applications and uses expanding ， PLC itself is also such a

situation is developing rapidly. PLC causing production costs continued to decline in

the premise ，to maintain a higher integration and reduce the size and increase their

capacity to enhance the speed，ease of use and enhanced overall performance trends .

PLC has a current due to low prices ，high reliability，applicability，easy to use and

flexible，and easy to maintain and modify ，in various industry sectors worldwide has

been widely used.

Due to the rapid development of domestic manufacturing ， transportation and

production materials traditional manual methods to increase productivity has become

into automation ，greatly improving production efficiency at the same time ， also

liberated workforce to ensure production safety and reduce the production

requirements of the environment ， and to some extent ， improve the degree of

production automation .

The design of the history and current situation of PLC haul the car as a starting
