【摘要】：嵌入式定时器是集多功能、高精度、显示直观、控制方便于一体的定时预报功能电子仪器。为满足科研工业的需要，完成对工业仪用定时器的设计研究具有重要意义。本文提出一种基于FPGA的嵌入式仪用定时器，具有计时、定时、调时、报警等功能。系统采用的核心芯片是Cyclone II FPGA芯片，以QuartusII作为软件开发平台，采用VHDL语言，对定时器进行SOPC设计，并应用Protel99SE，制作PCB电路板，完成系统硬件电路设计。本设计可通过人机交换单元显示具体的世纪、年、月、日、时、分、秒，，同时具有倒计时的功能，并且能够定时警报。通过控制系统可以实现定时调时、切换显示及解除警报。本系统的集成度高，可实现高精度定时计时，其外围电路简单，灵活性好，方便以后的产品升级，实现更广泛的应用。
[Abstract]:Embedded timer is an electronic instrument with multi-function, high precision, visual display and convenient control. In order to meet the needs of scientific research industry, it is of great significance to complete the design and research of timer for industrial instrument. This paper presents an embedded instrument timer based on FPGA, which has the functions of timing, timing, timing, alarm and so on. The core chip of the system is Cyclone II FPGA chip. QuartusII is used as the software development platform and VHDL language is used. The timer is designed by SOPC, and the PCB circuit board is made by using Protel99SE. this design can display the concrete century, year, month, day, hour, minute and second through man-machine exchange unit, at the same time, it has the function of countdown. And can timing alarm. Through the control system can achieve timing adjustment, switch display and remove the alarm. The system has the advantages of high integration, high precision timing, simple peripheral circuit, good flexibility, convenient product upgrade and wider application.
