    摘要:

    为了避免在硬塑料管道工程建设中塑料管道参数测量的误差,设计了一套探测管道内钢珠运动状况测量系统,系统整体设计由单片机控制模块、传感器测量模块、信号处理电路、显示电路和机械装置等多个部分组成。系统硬件以STM32F103单片机为控制核心,以ExEX-2E1-Z金属传感器与SCA61T-FA1H1G倾角传感器为关键测量模块。系统软件主要使用KEIL 5软件对STM32F103单片机完成编译程序,以此来驱动金属传感器与倾角传感器对数据的测量分析,得出钢球的运动状况,并通过彩色液晶显示模块显示出钢球运动状况测量结果。在测量方法上,采用最小二乘法建立倾斜角计算模型来进行曲线拟合,从而实现角度测量。系统整体功能主要为了实现在非透明没有加工痕迹的硬塑料管材中测量出钢球数量、方向、周期以及角度等运动状况测量数值。

    Abstract:

    In order to avoid the error of measuring the parameters of plastic pipes in the construction of hard plastic pipes, a measuring system for detecting the movement of steel beads in pipes is designed. The hardware of the system is controlled by STM32F103 single chip microcomputer, and the key measurement module is ExEX-2E1-Z metal sensor and SCA61T-FA1H1G inclination sensor. The system software mainly uses KEIL 5 software to compile the STM32F103 single-chip microcomputer, in order to drive the metal sensor and inclination sensor to measure and analyze the data, get the movement of the steel ball, and display the measurement results of the movement of the steel ball through the color LCD module. In the measurement method, the least square method is used to establish the calculation model of inclination angle, and curve fitting is carried out to achieve angle measurement. The overall function of the system is to measure the number, direction, period and angle of steel balls in non-transparent hard plastic pipes without machining marks.
