    • PURPOSE: A system for protecting a digital atomic reactor without common software troubles and a high-reliability software manufacturing method for the same are provided to improve safety and reliability of a digital atomic reactor protecting system by thoroughly removing the common troubles and to autonomously inspect software designing. CONSTITUTION: The system comprises four channels(A,B,C,D). Each channel comprises a BP(Bistable Processor)(20), an LCL(Local Coincidence Logic Processor)(30), an SIP(System Interface Processor)(40), an initiation logic(50), and an MTP(Maintenance and Test Panel)(80). Software condition specifications are written out by using a state diagram. A design description of each software using different operating systems is written out. Each software is coded based on the design description. A module test of the coded software is performed. The test result of the software is compared to check the generation of errors.
    • 目的:提供一种无普通软件故障的数字原子反应堆保护系统及其高可靠性软件制造方法,通过彻底消除常见故障并自主检查软件,提高数字原子反应堆保护系统的安全性和可靠性 设计。 构成:系统包括四个通道(A,B,C,D)。 每个通道包括BP(双稳态处理器)(20),LCL(本地一致逻辑处理器)(30),SIP(系统接口处理器)(40),启动逻辑(50)和MTP(维护和测试 面板)(80)。 软件条件规范通过使用状态图来写出。 写出使用不同操作系统的每个软件的设计描述。 每个软件都是根据设计描述进行编码的。 执行编码软件的模块测试。 比较软件的测试结果,检查错误的产生。
