The invention relates to the technical field of electronic component reliability engineering and environmental engineering, and discloses an electronic component environmental adaptability reliability prediction and life evaluation system and method, and the system comprises an environmental parameter collection module, a reliability prediction module, a life evaluation module, and a data storage and interaction module. According to the invention, a multi-dimensional sensor array including temperature, humidity, vibration, electromagnetic radiation and salt mist concentration is adopted by an environmental parameter acquisition module, multi-physical field stress parameters are synchronously acquired, and common environmental interference factors of electronic components are covered; a Kalman filtering algorithm is built in the data preprocessing unit to suppress environmental noise, the noise suppression ratio is increased by 40%, then abnormal values are eliminated through the 3 sigma criterion, and the data integrity reaches 99% or above; besides, the stress simulation sub-module realizes single / multi-stress coupling simulation through a temperature control cabin, a vibration table and the like, and ensures that the simulation stress steady-state error is less than or equal to 1% in combination with PID feedback control, so that extreme environment data of a laboratory can be supplemented, and the problem of insufficient field data is solved.

The utility model discloses an environmental engineering cleaning device relates to environmental engineering technical field, include: support, the mechanism of shattering is equipped with multiple groups, multiple groups of mechanism of shattering are all equidistance and are located in the support, are used to break the ice on the handrail, and each group of mechanism of shattering all includes control part, moving part, two shattering head and shattering box, and shattering box fixed connection is in the support, and moving part is located in the shattering box, and two shattering head all are located on moving part, and control part is located on moving part. The environmental engineering cleaning device, through the use of mechanism of shattering, can shatter the ice layer on the handrail, avoid cleaning not clean, cause the influence to personnel, and, simple structure, simple to operate, the environmental engineering cleaning device, through the use of blowing mechanism, can blow off the ice layer of shattering, and, cooperate temperature control stick, can carry out hot -blast processing, melt the fine ice chippings, keep the handrail dry.
