Research Of On-line Monitoring System Of Crane Stress Of Structure Base On Wireless Transmission

Crane as a handling equipment,Widely used in factories,the freight yard,ports and other places,and it becoming larger,heavier and faster accordingly;plays an important role In the cargo industry.As a frame of crane machinery,metal strcture is enduring the weight of transmission mechanism itself and other load.Metal structure's working condition relates directly to the whole machine'soperation performance,safety and reliability.Malfunctions could cause great direct and indirect loss.Traditional stress monitoring system of Crane.Stress signal long trassmit using wire,or Staff directly to tens of meters high on machinery and equipment acquisition to monitor the signal.Long transmission lines not only increase the cost,If the measurement of objects in the movement area or isolation,the use of wire transmissions will bring a lot of inconvenience.Long-term real-time online monitoring,an important issue is the issue of data transmission signals.Ethernet in many fields with a wide range of applications,many of the original equipment and systems independent with Ethernet connectivity,so more and more long-distance transmission of information equipment possible.Crane-line monitoring system for such equipment on the sharing of information resources to provide the material means.In the field of industrial control has urgent needs and a broad market,so more and more enterprises and individuals committed to research in this area.In recent years,the signal transmission provides great convenience.Detection system as an important link in the data acquisition and transmission technology has changed dramatically.Compared to the traditional way of data transmission,wireless transmission over long distances without considering the installation of transmission cables,saving a large number of cables and systems to reduce the difficulty and cost of construction,in particular,is very convenient for staffto reach the region,a great prospect.Crane-line monitoring system of the crane wireless real-time online monitoring, has changed the tradition of previous monitoring tools,greatly increased the degree of automation,monitoring crane.To improve the structure of the crane damaged and emergency response speed and shorten the time for fault monitoring and maintenance to ensure the early detection,early maintenance,an increase of normal working hours,increased production efficiency.The adoption of modern automation and control,computer network technology,wireless communications and other technology,changes in the original self-isolation of a single control,automatic monitoring network to achieve a crane control and management of intelligent network.The adoption of network technology,acquisition of signal crane or information,combined with multimedia technology,the realization of a crane electrical control system of computer graphics of a comprehensive monitoring,fault monitoring and tracking the operation of agencies such as status,fault type and fault points.In this paper,The mechanical structure in order to lifting stress for the object, from the lifting of mechanical characteristics of metal structures,combined with the specific working conditions machinery,metal structures for stress Lifting-line monitoring system to undertake a study to test and test of modern mechanical technology To study the means of traditional strain measurement method,based on wireless data transmission line monitoring system design for the system hardware configuration and software programming.Use of existing network resources,engage in play network coverage,such as transmission characteristics of a good advantage for data collection to provide a wireless data transfer and convenient way to keep the structure of the work load lifting equipment technical state of the realization of the effect heavy machinery metal structure online long-term monitoring.This will not only improve the monitoring of the degree of automation,you can save a lot of human and financial resources,convenient and have a high practical value and economic value.This paper is divided into four parts,The first part of a wireless local area network and its monitoring of communication technology applications;the second part of the study stress crane wireless monitoring system,an analysis of the principle of strain measurement and method;the third part of research crane-line monitoring of the hardware facilities;article four parts of the system part of the programming software development,data collection and storage.
