一、概述目前 SHARP PC—1501计算机广泛应用于水利部门,但多数用户仅将它作为一种计算工具来使用。如果把它和测试仪器连接起来,构成数据自动同步采集及处理和最小控制系统,将大大提高量测、控制精度和工作效率。在水工模型试验中,水位、流量是两个基本的参数。然而目前多数模型试验中,对它们的获得,都是采取人工目测,人工记 I. Overview At present, SHARP PC-1501 computer is widely used in water conservancy department, but most users only use it as a calculation tool. If it is connected with the test equipment to form the data synchronization and acquisition and processing of automatic control and minimal control system, will greatly improve the measurement, control accuracy and efficiency. In the hydraulic model test, the water level and the flow rate are two basic parameters. However, most of the current model tests, to obtain them, are taken by artificial visual inspection, manual
