面向立体仓库控制系统的 16 路通用输入模块设计摘要立体仓库系统作为一种用于存取的仓储系统,正被广泛应用于产品存储、配送以及生产运输过程中。由于现在的工业高度发达,市场对自动化立体仓库系统的控制要求越来越高,许多自动化的设备和传感监测仪器都需要接入控制系统,对系统的接口能力就提出了更高的软硬件要求,通用输入模块需求越来越迫切。目前通用输入模块的市场成本较高,两路模拟量输入,两路开关量输出的测控模块售价高达 1800 元左右。如此高的价格阻碍了计算机控制技术的进一步推广,尤其是在中小企业的普及。每种单元模块的通道数少,过少的通道会降低系统的集成度,提高集成的成本。不能自成系统独立工作。很多应用场合既要求测控模块在联网后作为主机的输入接口模块使用,也要求其具有脱机可单独进行测控的能力。而目前的测控模块仅可作为主机的接口模块使用,不具备脱离主机独立工作的能力。本文为了解决这些问题,利用单片机技术,设计多通道数,或可以方便地对通道进行扩展的 16 路通用输入模块。尽可能做到使用户对单台设备进行控制时,不重复选择同一模块,避免了造成不必要的硬件冗余,从而降低生产成本。关键词:立体仓库,通用模块,单片机,输入接口II Design of 16 Universal Input Modules for Stereoscopic Warehouse Control SystemAbstractAs a storage system for access, the three-dimensional warehouse system is widely used in product storage, distribution, and production and transportation. Due to the highly developed industry, the market is increasingly demanding control of automated warehouse systems. Many automated equipment and sensing monitoring instruments require access control systems, and higher hardware and software are proposed for the interface capabilities of the system. Requirements, universal input module requirements are becoming more and more urgent.At present, the market cost of the universal input module is relatively high, and the two-channel analog input and the measurement and control module of the two-way switch output are as high as 1,800 yuan. Such high prices have hindered th...
