The use of equipment such as oscilloscopes, high-speed cameras or acoustic sensors is quite common to measure detonation times from surface connectors and detonators. However, these solutions are expensive and, sometimes, not adequate to use in field conditions, such as mining or civil works. In this regard, a low-cost portable device is designed and tested using the Arduino platform, achieving a simple, robust and precise system to carry out field measurements. This study describes the characteristics and working principles of the designed device, as well as the verifications carried out to check the accuracy of the Arduino ceramic oscillator. Additionally, a field test was carried out using 100 actual detonators and surface connectors to verify the correct operation of the designed equipment. We have designed a device, and a methodology, to measure detonation instants with a minimum accuracy of 0.1 ms, being sufficient to carry out subsequent studies of detonation time dispersion for non-electric detonators.
使用示波器、高速摄像机或声学传感器等设备来测量表面连接器和雷管的起爆时间是相当常见的。然而，这些解决方案成本高昂，而且有时在诸如采矿或土木工程等现场条件下并不适用。在这方面，设计并测试了一种使用 Arduino 平台的低成本便携式设备，实现了一个用于进行现场测量的简单、坚固且精确的系统。本研究描述了所设计设备的特性和工作原理，以及为检验 Arduino 陶瓷振荡器的准确性所进行的验证。此外，使用 100 个实际雷管和表面连接器进行了现场测试，以验证所设计设备的正确运行。我们设计了一种设备和一种方法，用于测量起爆瞬间，最小精度为 0.1 毫秒，足以对非电雷管的起爆时间分散进行后续研究。
