摘要

在该项目中，我们设计并建造了一个教学模块，以实际方式让学生了解以下相关概念：控制系统、仪器仪表、执行器、可编程逻辑控制器、SCADA 系统和控制算法。模块的主要组成部分包括主水箱、备用水箱、管道系统、配件、压差传感器、涡轮流量计、转子流量计、控制阀、电磁阀、伺服阀、离心泵、可编程逻辑控制器和个人电脑（PC）。通过实施 PID 控制算法，实现了流量和水位的自动控制。最后，还进行了运行测试，产生设定点的变化和干扰，以观察过程的响应和评估控制系统。关键词 - 控制系统、仪器仪表、流量控制、水位控制、PLC、SCADA、PID 控制器

Módulo didáctico para controlar nivel y caudal de agua, mediante sistema SCADA, PLC y algoritmo PID

In this project, design and construction of an educational module has been carry out, allowing understand in a practical way, the concepts related to: control system, instrumentation, actuator, programmable logic controller, SCADA system and control algorithm. Module’s principal components are main tank, reserve tank, piping system, fittings, differential pressure transducer, turbine flowmeter, rotameter, control valve, solenoid valves, servovalve, centrifugal pump, PLC and a personal computer (PC). With this, automatic flow and water level control were achieve, through the implementation of a PID control algorithm. In the end, operation tests have been perform, generating changes in set point, and generating disturbances, to observe the response of the process and assess the control system. Keywords — control system, instrumentation, flow control, level control, PLC, SCADA, PID controller
