摘要
现有的数字抢答器锁存功能比较复杂,且可靠性相对较低,为此,研究了一种基于现场可编程逻辑门阵列(FPGA)抢答信号锁存的设计方法.设计的电路由抢答电路、定时电路、报警电路、时序控制电路、译码器电路和数码管显示电路组成,可实现抢答命令与计时起点同步,提高了数字抢答器的稳定、可靠以及灵敏度.与现有的数字抢答电路相比,所设计电路的应用场景更广泛,行业认可度更高.
Abstract
The existing digital responder has a complex latch function and relatively low reliability.Therefore,a design method based on field programmable gate array(FPGA)for response signal latch has been studied.The designed circuit consists of a response circuit,a timing circuit,an alarm circuit,a timing control circuit,a decoder circuit,and a digital display circuit.It can achieve synchronization between response commands and timing starting points,improving the stability,reliability,and sensitivity of the digital responder.Compared with existing digital response circuits,the circuit designed in this paper has a wider range of application scenarios and higher industry recognition.
