| 摘 要： | 容栅传感器具有性价比高、体积小、环境适应能力强等优点,在与位移有关的各类测试中已获得广泛的应用。为实现远距离现场测试监控,介绍一种对容栅传感器输出信号进行接收处理的方案。该方案基于TMS320LF2407中的capture单元和SPI模块,在软件上采用两个中断的方法来实现,经实验证明数据接收稳定可靠。相对单片机处理电路而言,该方案电路外围元器件少,处理速度快,可靠性高且编程方便,在车间现场环境恶劣的位移测试中具有一定实用价值。

| Abstract: | Due to the high cost performance,small volume and good adaptive capacity to the environment,the capacitive gate sensor has been widely used in the test engineering relating to the displacement.To achieve long-distance monitoring,a scheme about receiving and processing the output signals from capacitive gate sensor is introduced.Based on the capture unit and SPI module of the TMS320LF2407 microcontroller,the circuit is designed to complete processing the serial signal from the sensor by interrupt algorithm i... |
