Research And Development Of Construction Machinery Working Condition Parameter Monitoring And Fault Alarm System

With the rapid development of microelectronic technique,the integration level and performance of integrated circuit is enhanced and its price is reduced.Especially,the emergence of single-chip microprocessor brings a new technique innovation to today抯 domain of industry measurement and controlling.It has been urgent affairs that the work condition of construction machinery is real-time monitored and its malfunction is predicted well and truly with work condition monitoring and malfunction alerting system which has high reliability and quality on various of construction machineries. This paper introduces in detail the overall system designing thoughtway of work condition monitoring and malfunction alerting system of construction machinery and the design technique of its hardware schema circuit and software program on the basic of comparative analysis to the cognate systems at home and abroad.This system with the core of MCS-51 single-chip microprocessor,followed with some processing circuits,whose monitoring program is composited with assembler language,completes the sampling and calculating of work condition抯 parameters and has the functions such as the real-time displaying and transmitting of parameters,malfunction alerting,and so on.Moreover,this paper adopts a series of software-and-hardware measures of protection so as to improve the anti-interference ability of the system. The final result of the experiment indicates that the whole system works accurately and credibility , realizing the presumed object.
