基于STC8单片机的净水车控制系统的设计

Design of Water Purification Control System Based on STC8 Single Chip Microcomputer

摘要:

随着人民对的户外用水安全的问题的广泛关注，市面上出现的越来越多的净水车设备，这些净水车的安全的运行离不开一套稳定的控制系统的控制。为了实现对净水车净水流量和净水过程的操控，开发了一套基于STC8系列单片机的净水车控制系统。该系统主要分两个部分：一是根据可移动净水车净水工艺流程图确定系统的整体操控流程。二是单片机收集液位传感器、流量传感器反馈的信号，来控制系统的整体安全稳定运行，并通过串口通信接收和发送数据，来连通触摸屏完成人机交互，该系统具有当流量高于500L/H或低于50L/H时，调节潜水泵的频率来保护净水过程的安全运行，并可实现自动运行等特点。

Abstract:

With people's extensive attention to the issue of outdoor water safety, more and more water purifier equipment appears on the market. The safe operation of these water purifiers cannot be separated from the control of a stable control system. In order to realize the control of the water purification flow and water purification process of the water purification vehicle, a set of water purification vehicle control system based on STC8 series single-chip microcomputer was developed. The system is mainly divided into two parts: one is to determine the overall control flow of the system according to the water purification process flow chart of the mobile water purifier. The second is that the single-chip microcomputer collects the signals from the liquid level sensor and the flow sensor to control the overall safe and stable operation of the system, and receives and sends data through serial communication to connect the touch screen to complete human-computer interaction. When it is below 50L / H, adjust the frequency of the submersible pump to protect the safe operation of the water purification process, and can realize the characteristics of automatic operation.
