摘要: <正>笔者设计了一种采用PLc控制的桥堆老化台电气控制系统,具体论述了桥堆老化台进行电气控制的原理及主要特点,介绍了以微处理器为核心的可编程控制器来实现系统的工作流程控制、采样分析、数据处理、自动巡检、报警等功能。控制系统实现了触摸屏人机对话、自动巡检次品并报警的功能,可调直流电源参数对桥堆正向老化所需要的交流电压参数和进行桥堆反向老化所需要的高精度进行自动控制。

Abstract: Combining forest resource surveying for planning and design, spatial database and attribute database of forest plots were established in county level. Based on commutative relationship between spatial data and attribute data, visual and multiple management information system was generated by means of modularization with input, searching, analysis, displaying and output integration. This information system can supply an aid-decision method in forest resources management and forest survey, planning and design.
