1背景生产非标准设备的机电企业生产所需的电气材料元件涉及种类繁多,使得库存管理面临着非常大的压力,例如元件出入库时寻找货架的位置十分困难,元件库存盘点难度较大,使得库存补充计划比较难以制定,一部分元件库存积压而另一部分库存短缺的状况同时存在,此外由于产品设计人员对库存情况缺乏了解,使得一些积压的元件不能快速有效地应用到新产品开发中。基于上述情况,利用CAN总线 1 background The production of non-standard equipment, electrical and mechanical enterprises need a wide range of electrical material components, making inventory management is under great pressure, such as components out of storage to find the shelf location is very difficult, inventory inventory difficult parts, making Inventory replenishment plans are more difficult to set up, with some of the inventory overstocking and some inventory shortages concurrent. In addition, due to lack of knowledge of product inventories, some backlog components can not be quickly and effectively applied to new product development. Based on the above situation, the use of CAN bus
