Industrial process measurement and control equipment is the basis for survival and development of the mechanical industry, related to the lifeblood of the national economy, at the same time, industrial measurement and control equipment widely used at high temperature and strong corrosive environment, with high reliability requirements. Traditional reliability analysis method is derived from electrical and electronic industry, based on the probability and statistics, in conformity with industrial measurement and control device characteristics, greatly limits the development of industrial measurement and control industry reliability, this paper presents a reliability based on failure physics theory analysis method, found the fault mode, with the simulation analysis and physical test, the product has carried on the accurate life is expected to verify the feasibility of this method, the reliability method worth to further research and promotion.

For a long time, reliability plays an extremely important role in electrical automation control equipment. To improve electrical automation control equipment’s reliability, the job should be promoted to a strategic height so as to assume and effectively control the factors affecting the reliability of the equipment, thus ensure the accuracy of reliability test. This paper, based on this, first is to implement the reliability influence factors analysis, and then introduces the main testing methods. By contrast, it finally comes to the conclusion that this article can provide certain reference for the research of related topics.

In the process of mechanical automation, due to the development of drive equipment in diversification, miniaturization, digitalization, intellectualization and the development of sensor in miniaturization, digitalization, visualization, on the one hand, automation mechanical structure become simple, on the other hand, with the increase of the dependence on control equipment for automation machinery, an automated machinery needs many kinds of control mode and means to complete the production. With the improvement of mechanical motion complexity, there will appear accumulation phenomenon of control equipment, in addition, in order to complete the data transfer between all kinds of control equipments, each control equipment need to build all kinds of communication protocol and special cables to connect. In order to solve the "accumulation" phenomenon, control equipment manufacturers competing to launch the new scheme. In this paper, a control project based on the control products of Mitsubishi electric company was proposed, which illustrates the change of the control way of mechanical automation. Once you master the control platform of these companies, will be able to build or integrate corresponding control system.
