Abstract
Objective:Based on the research of the integrated timer system, and its applications in the field of medical engineering, it illustrated the advantages of integrated timer system, and then demonstrated its application values in the field of the future.Methods: With 555 time base timer as the core chip, and added a small amount of resistances and capacitances, they can form stable performance, precise multivibrator, monostable trigger circuit, Schmitt trigger circuit to drive the work load.Results: With a 555 time base integrated circuit as the core of integrated timer, the integrated timer system runs stably and has some other advantages on high precision, wide application and low consumption. Conclusion:It will have a wider application prospect in science and technology, military, medical and other fields ,for the integrated timer delay circuit’s simple structure simple, low cost, high accuracy, etc. <br> Objective:Based on the research of the integrated timer system, and its applications in the field of medical engineering, it illustrated the advantages of integrated timer system, and then demonstrated its application values in the field of the future.Methods: With 555 time base timer as the core chip, and added a small amount of resistances and capacitances, they can form stable performance, precise multivibrator, monostable trigger circuit, Schmitt trigger circuit to drive the work load.Results: With a 555 time base integrated circuit as the core of integrated timer, the integrated timer system runs stably and has some other advantages on high precision, wide application and low consumption.
