针对靶场现有的时间间隔测量设备普遍存在体积大、功耗高且无直流供电方式的弊端,提出了一种小型直流靶场多通道时间间隔测量装置的低功耗设计方法。该方法基于器件选型和功耗优化两方面,成功降低了时间间隔测量装置内部各模块的电流消耗量。不同环境温度下时间间隔测量装置连续工作时间长度测试结果表明:时间间隔测量装置系统功耗有效下降,最长工作时间达12 h,增强了靶场速度测试的可靠性和便捷性。

Due to the disadvantages of large size, high power consumption and no DC power supply method in the existing time interval measurement equipment at the range, a low-power design method for a small DC shooting range multi-channel time interval measurement device is proposed.This method successfully reduces the current consumption of each module in the time interval measurement device based on the two aspects of device selection and power optimization. The test results of working time lengths under different temperatures show that the power consumption of the device is effectively reduced, and the maximum working time is 12 h, which effectively enhances the reliability and convenience of the range test.
