摘要
介绍了一种采用复杂可编程逻辑器件(FPGA)对触发控制信号、载荷标识电压信号进行同步采集、处理,并实现同步控制信号输出、控制信号状态和电压状态的实时监测和显示功能设备的设计与实现。本设计以FPGA为控制核心,设计控制信号采集、信号处理、同步信号生成、电压信号采集、LCD显示和电源处理6个模块。验证结果表明,该设备运行稳定、精度高、可靠性强,并且成本和维护费用低。
The design and realization of a kind of detection device is introduced in the paper.The device uses FPGA to collect and process the trigger signal and load identifier voltage signal synchronously,realizes the synchronous control signal output,and can monitor and display the control signal state and voltage signal state.FPGA is the core of the device,and the device has six modules which are control signal acquisition,signal processing,synchronous signal generation,voltage signal acquisition,LCD display and power processing.The test results show that the device operates stably and has high precision,low cost and maintenance.
