| tUnder the study of crane security monitoring system at home and abroad,an advanced intelligent multi-functional security monitoring system for crane is developed,which takes advantages of the technology progress in the fields such as electronic,computer,sensing and controlling.The system not only performs the general functiona such asdecting,controlling,alarming and so on ,but also possesses LCM interface to report parameter and working condition in Chinese,real time demo of crane work condition,and the black-box module to record the history data of overload state. The system has the function of real clock ,fufil the request of time imformation,ameliorate the system function. The system explored in the intelligent function of self-study which improved the universal quality.The system has the function of self-study .It simplify the cockamamie course of crane parameter import,advanced the handy course of system seting and debug,largely advance the currency of the crane.Without change any software and hardware,the same system can apply in different crane.To perfect the function of the system ,improve the advances ,and guaranty the credibility,the paper develops new Security Monitoring System.Paper design the circuit and compiling program with C-51 language.The system design adopts modularization and framework.In addition,this paper adopts a series of hardware and software protecting measures to enhance the ability of anti-jammimg.The final result of the experiment indicates that the whole system works accurately an credibility,realizeing the presumed object. |
