近几年来,水工模型试验要求施放随时间变化的流量过程,以达到更真实地模拟天然洪水灾情和更深入地研究它对各种水工建筑物的影响。1978年采用了流量及人工降雨自控系统(见方框图1),进行板桥水库溃坝模型试验,溃坝水流要求自控系统在几分钟内完成一个流量过程。因此我们先后研制了快速跟踪的程序给定器及用TP-801微型计算机来给定流量过程。以下仅介绍TP-801微型计算流量给定装置。
In recent years, hydraulic model tests have required the application of flow rates over time to simulate a more realistic flood disaster and to examine more deeply its impact on various hydraulic structures. In 1978, the flow and artificial rainfall automatic control system was adopted (see the block diagram 1) to carry out the dam breach model test of Banqiao Reservoir. The damped water flow required the automatic control system to complete a flow process within a few minutes. Therefore, we have developed a fast track program setter and the TP-801 microcomputer to give the flow process. The following only introduces the TP-801 micro-computing flow reference device.
