摘要
通过对地铁杂散电流评价方法的分析,结合模糊综合评价方法,给出了地铁杂散电流模糊综合评价方法;利用MATLAB对该方法进行了仿真分析,并通过广州地铁一号线杂散电流监测系统得到的数据对杂散电流状况进行了评价.结果表明,模糊综合评价方法可以减少漏报率,提高地铁杂散电流腐蚀状态评价的准确性.
The paper analyzed characteristics of present stray current evaluation methods, and introduced the principle of fuzzy comprehensive evaluation method, providing a fuzzy comprehensive assessment of the MTR stray current. Using MATLAB, its simulation analysis is carried out, and the evaluation for the Guangzhou No. 1 metro line stray currents is given with the data from stray current monitoring system. The results showed that the fuzzy comprehensive method can reduce error probability, and increase the accuracy of MTR stray current corrosion evaluation.
