One, pay attention to reliability design

    Reliability (Realizability) theory is widely used in the fields of engineering technology, its branches -- reliability analysis and design is widely applied in the design of intelligent instrument in advanced. We must have a profound understanding to a high level of product to leave high reliability assurance is waste. Intelligent instrument of foreign advanced, at the design stage will pay great attention to the reliability analysis and design. Applying the reliabilitydistribution theory, the reliability index from the system to component level, component level is assigned, so that the reliability of the whole machine is guaranteed. When the reliability index of a part can not be met, can use redundantdesign scheme to realize the gold. The flow chart of some reliability design can be seen, the parallel redundantmethod is generally used in meter design. In high reliability applications (reliability of R ≥ 0.999), especially in computer control system, the redundancy method.

    The foreign intelligent instrument not only pay attention to the reliability design of instrument itself, and the use of the bad sex should be design considerations. The reliability of general electronic instrumentation products belong to theexponential distribution, and machining parts multi instrument reliability belong to normal distribution, the actual calculation is not very complicated. The instrument design in China should pay attention to it, this is a key link in the quality of the products.

    Two, pay attention to maintainability design

     Repair to live (Maintainability), including not only the use of repair products, also includes a calibration function,production equipment debugging function and repair function and other technical indicators, repair live must be guaranteed in the design stage. The foreign intelligent instrument, with high degree of repair, make it to production debugging and repair, including in the design in the implementation of automatic detection system. This designproducts to users in the measurement and use of the process provides a great convenience.
