2、、单片机等方案来实现。 其中用标准逻辑器件来实现电路在很大程度上要受到逻辑器件如门电路等 的影响,调试工作极为不易,而单片机编程复杂不容易掌握。因此,最终我们选 择了用可编程的控制器 PLC 来实现系统功能的设计。 可编程序控制器 PLC 在工业自动化中的地位极为重要, 广泛的应用于各个行 业。随着科技的发展,可编程控制器的功能日益完善,加上小型化、价格低、可 靠性高,在现代工业中的应用更加突出。料箱少料报警装置采用的可编程制器具 有可靠性高、维护方便,用法简单、通用性强等特点,本文用三菱 FX2N 的可编 程控制器控制料箱少料报警装置来说明可编程控制器硬件、软件的设计。 关键词关键词:PLC
3、 料箱 报警装置 程序控制 3 Abstract Along with the development of the industry, automation has been occupying the important status in daily and production. Automation is not only can save the labor cost, but also can liberate the workforce, more let people have more free time to do more work, which greatly pro
4、moted the social progress and development. The container less expected alarm device is belong to the category of this class, with this device, people dont have to always keep beside the material box, also can have more time to do other things. Realize the container less many alarm system control met
5、hod, can use the standard logic devices, programmable controller PLC, SCM, etc. Among them using standard logic devices to implement circuit in large part to influenced by logic devices such as gate, debugging is very not easy, and single-chip microcomputer programming complex is not easy to learn.
6、So, finally we chose to use PLC programmable controller to realize the system function design. Programmable controller PLC is very important in the position in industrial automation, is widely used in various industries. With the development of science and technology, more perfect the function of the programmable controller, combined with min
