摘要
近年来,我国的演艺产业正处于快速发展时期,舞台机械装备的大量使用在丰富演出效果的同时,也带来了一系列安全隐患,增加了演出事故发生的可能性。演出安全要求的提高对在役舞台机械装备的使用和维护提出了更高的要求。本文以安全标准ISO 13849为基础,结合安全完整性评估理论,研究了面向在役舞台机械装备的安全完整性评估技术方法。论文采用风险图法对在役舞台升降台进行了风险评估,参照安全标准ISO 13849对某在役舞台升降台的安全回路进行了PL/SIL等级的计算,验证结果表明该在役舞台机械装备的安全回路满足功能安全要求,采用的评估方法可行、有效。
In recent years,the performing arts industry in China has been undergoing rapid development.The widespread utilization of stage mechanical equipment not only enhances performance effects but also brings a series of safety hazards,increasing the possibility of performance accidents.The higher safety requirements for performances impose greater demands on the operation and maintenance of the in-service stage mechanical equipment.Based on the safety standard ISO 13849 and the theory of safety integrity assessment,in this paper technical approaches for evaluating the safety integrity of the in-service stage mechanical equipment were explored.Using the risk graph method,a risk assessment of in-service stage lifts was conducted,guided by safety standard ISO 13849,and specific PL/SIL levels for the safety-related loops of in-service stage lifts was determined.The results indicate that the safety-related loops used meet the safety requirements,and the mothed proposed here is feasible and effective.
