    摘要:

    爆炸场参数测试现场环境比较恶劣,为提高触发控制器的可靠性与稳定性,设计了基于FPGA的高性能同步触发器。分别基于独立元器件与FPGA设计了触发控制器,并根据爆炸参数测试要求设计相关参数,同时分析了采用FPGA芯片设计带来的稳定性与可靠性等优点。通过多次实际实验表明,基于FPGA的触发控制器在极端温度条件下各通道同步时间小于50 ns,误触发率为0,具有更高的稳定性与可靠性。

    Abstract:

    AS site environment of the shock parameters test was quite poor. A high performance trigger controller based on FPGA is designed to improve the reliability and stability. Based on the independent components and FPGA, two sets of trigger controllers are designed. And parameters are designed according to the testing requirements of explosion. The advantages including stability and reliability which brought by using FPGA are analyzed. The results show that the synchronization time of the trigger controller based on FPGA is less than 50ns under the condition of extreme temperature, and the error trigger rate is 0, which has higher stability and reliability.
