The invention discloses an automobile engine fault positioning method based on data analysis, and belongs to the technical field of automobile fault detection, and the method comprises the steps: 1, drawing up normal operation data intervals of all monitoring items of an engine under different environment condition values; 2, judging whether the operation data of each monitoring item under the environment condition value is normal or not according to the acquired operation data information; 3, when the operation data of the monitoring project is abnormal, generating a corresponding fault alarm, and determining the danger level of the fault; and 4, when the operation data of the monitoring items are normal, predicting whether each monitoring item has a potential fault risk or not. According to the method, when the engine does not have a fault, whether each monitoring item has a potential fault risk or not is predicted according to the historical accumulation condition of the operation data of each monitoring item position, so that a user can be timely reminded to perform corresponding inspection and maintenance on the corresponding position, and the occurrence of the fault is avoided.
本发明公开了一种基于数据分析的汽车发动机故障定位方法,属于汽车故障检测技术领域,包括步骤一、拟定发动机各监测项目在不同环境状况值下的正常运行数据区间;步骤二、根据获取的运行数据信息来判断该环境状况值下的各监测项目的运行数据是否正常;步骤三、当监测项目的运行数据不正常时,则生成对应的故障报警,并确定故障的危险等级;步骤四、当监测项目的运行数据正常时,则根据预测各监测项目是否存在潜在故障风险。本发明在发动机未出现故障时,根据各个监测项目位置的运行数据的历史累计情况来预测各监测项目是否存在潜在故障风险,从而可及时的提醒使用人员对相应位置进行对应的检查维修,从而避免故障的发生。
