自今年3月31日起,欧洲市场的新车必须配备eCall系统,目前法规执行的是eCall 2.0标准,是基于GSM/UMTS的in-band modem技术,简单的说是基于语音通道传输最小数据集(MSD),而下一代基于PS域的eCall技术,主要是基于IP技术来实现MSD的上传以及双向的语音通话。

eCall MSD解码器 一个基于Python Tkinter的GUI,用于解码MSD(最小数据集)。 互联网上很少有MSD解码器,因此我为对eCall和MSD感兴趣的任何人创建了此工具。 介绍 eCall是一种泛欧洲的车载紧急呼叫系统,在发生事故时,它会通过蜂窝网络使用欧洲紧急号码112。 eCall可以手动放置,例如按一个按钮,或者在汽车安全系统检测到紧急情况后自动放置,例如由于安全气囊展开而自动放置。 最小数据集(MSD)包含车辆信息,例如位置,车辆识别号等。预期的好处是可以使紧急服务人员Swift意识到事故,将获得准确的位置信息,从而能够到达事故受害者速度更快,有潜力每年挽救数百条生命。 描述 菜单 计算器:许多有用的网络链接可帮助您进行计算。 工具: 位置服务转换器:将CAN GNSS信号转换为可读的LAT / LNG,反之亦然。 MSD历史记录:存储您的MSD解码历史记
