This paper discusses every kind of risk in laws , management system , personnel , market structure , infrastructure , emergency system , safety management , combines the active safety evaluation methods with risk conception , and brings a method of multi - stage fuzzy comprehensive evaluation and gives detailed numerical examples . the systematic way of risk control to is put forward in safety evaluation dynamic management system , law system , management system , economic method , personnel , scientific method , revolution relationship and grid construct , and according to inland and outland status , a management system of " three standards together " is also presented to give consult in the safety management of the grid enterprises in our country 从法律法规、管理机制与人员素质、市场结构、基础设施、应急机制等多个方面系统论述了电网企业在安全管理中所面临的各种风险；基于当前电力企业中所采用的安全性评价方法，将现有方法与风险理念相结合，提出了安全评价的多级模糊综合评价方法，通过算例进行了的说明；针对风险识别中得出的电网企业所面临的多种风险，分别从安全性评价动态管理体系、法律体系、管理体系、经济手段、人员素质、科技手段、改革关系和电网建设等多个方面提出了系统的风险控制办法，并结合国际、国内的现状提出了“三标一体”的管理体系，以期对我国电网企业的安全管理工作提供一定的参考。
It is a kind of active safety system . on the speedway , when the back vehicle approaches the rear of the forward one , the system will send out collision warning signals to remind the driver of avoiding rear - end collision accident . main investigations and phase fruit : 1 装有本系统的汽车在高速公路上正常行驶时，当本车车头接近前车车尾，并有可能与前车发生追尾碰撞时，该系统就会发出报警信息，从而提醒本车驾驶员采取制动减速或加速超车等措施以避免与前车发生汽车追尾碰撞事故。
As automobile running velocity ' s great increase and road traveling consistency ' s rapid accretion , the happening ratio of traffic accident has ascended continuously . wholly and reliably improving automobile ' s active safety performance offers the challenge for automobile designer and researcher as an impendent and difficult task 随着汽车行驶速度的显著提高和道路行车密度的急剧增大，交通事故的发生率逐年呈上升趋势，所以全方位、可靠地提高汽车的主动安全性能就成为摆在汽车设计、开发及科研人员面前一项紧迫而艰巨的任务。
The braking performance is one of the most important performance for the automobile , s active safety . it is very important that the braking performance is or not corresponded to the national standard requirement . the researches about the detecting system of automotive braking performance not only offer technical support and guidance for the science research and manufacture of the detection system , but also insure the traffic safety . so it is important to research more precise and automatic system 汽车制动性是汽车主动安全的重要性能之一,汽车制动性是否符合国家标准要求,对行车安全是非常重要的。同时汽车制动性能的检测研究也为制动性能的科研和生产提供了技术支持和指导。所以,研制高精度、高自动化程度的汽车制动性能测控系统具有重要意义。
