Abstract

Software is widely used in the railway system such as train propulsion system, brake system, train control system, train detection system and driver display unit. Unfortunately, there is no software criteria and development procedure that are required to get the qualified software. Although analysis and evaluation of each step in the software lifecycle are the basic activity, direct coding to get some required functions is the main activity in the railway industry. The evaluation is just carried out in the system level functional test. Because the software has uncertainty in itself and difficulty in evaluation due to the invisibility, Sophisticated and exhausted examination is required throughout the lifecycle. The MLTM (Ministry of Land, Transport, and Maritime Affairs) in Korea is trying to improve the software development ability in the railway industry, and to ensure the quality and safety of railway software following announcement of the safety criteria for the safety critical railway software. This paper suggests safety criteria and software development process for safety critical railway system for more detail description.

安全关键铁路系统软件安全标准及应用程序

软件广泛应用于铁路系统，如列车推进系统、制动系统、列车控制系统、列车检测系统、驾驶员显示单元等。不幸的是，没有获得合格软件所需的软件标准和开发过程。虽然分析和评估软件生命周期中的每个步骤是基本的活动，但直接编码以获得一些所需的功能是铁路行业的主要活动。评价只是在系统级功能测试中进行的。由于软件本身具有不确定性，并且由于不可见性而难以评估，因此需要在整个生命周期中进行复杂而详尽的检查。韩国国土海洋部公布了铁路安全关键软件的安全标准，为提高铁路行业的软件开发能力，确保铁路软件的质量和安全性，正在进行努力。本文提出了安全关键铁路系统的安全准则和软件开发过程，并对其进行了详细的描述。
