摘要

褐煤处理厂有许多传送带，它们是虚拟的。用于这些输送机的控制系统对工厂的安全运行至关重要。在现有的控制系统中，控制面板上有不同的模块和数量的继电器，使得电路非常复杂。在锅炉的每个角落都有四个主给料装置。每个主馈线由四个子馈线组成，每个子馈线由不同的模块组成。不同的模块有零转速模块，链条定位模块，煤流/无流模块和速度变送器模块。因此，它们占用更多的空间，需要更多的电缆来通信现场和控制面板。本文设计并仿真了一种基于单片机的通用控制面板。现场和控制面板之间采用简单的电缆通信接口，具有RS485多滴模式设施。

Modernization of lignite feeder control system using microcontroller with multidrop mode

Lignite handling plants are having number of conveyors and they are seen virtually. The control systems used for these conveyors are important for operating safe plant. In the existing control system, there are different modules and number of relays in control panel which makes the circuit very complex. There are four main feeder sets in each corner of a boiler. Each main feeder consists of four sub feeders and each sub-feeder consists of different modules. The different modules are Zero speed module, Chain positioned module, Coal flow/no flow module and Speed transmitter module. So, they occupy more space and needs more cables to communicate field and control panels. In this paper, a universal control panel is designed and simulated based on microcontroller. A simple cable communication interface is used between field and control panels with RS485 multi-drop mode facility.
