摘要
为了实现靶场时统终端输出IRIG B标准DC code信号,采用VHDL语言在FPGA逻辑电路中设计了DC code编码器硬件电路,通过QuartusⅡ软件建立工程文件对VHDL语言DC code编码器电路进行编译和仿真,获得了符合IRIG B标准的DC code信号。经过实践验证,该电路具有实现方法简单、电路稳定性好、精度高的特点,实测同步精度小于1μs。
In order to output IRIG-B standard DC code signal for the time system of shooting range, the DC code encoder hardware circuit is designed by using VHDL language on the FPGA logic circuit. The Quartus II software is used to to establish the project file for VHDL language, and compile and simulate DC code encoder circuit to get DC code signal according with IRIG-B standard. The practice shows that the circuit has simple realization method, good stability and high accuracy that the measured synchronous precision is 〈：1 μS.
