Research Of Wireless Monitoring System On Machine Performance On Container Terminal

The wireless control of the mechanical equipment is a integrative subject. In recent years, with the insistent need for high safty, the traditional wired control method challenge by trouble connected up, abominable working environment, Information transmission in time and so on. New-type wireless monitoring system based on sensor , PLC date collection , wireless communication and network technology , the new-type wireless monitoring systems of database technology have got extensive development and application, especially the technology of the wireless LAN is more and more convenient , swift , high-efficient and accurate. Such monitoring system based on wireless LAN is becoming development trend of the monitoring system now and later, Now ,the study on these field are getting more and more warmer , which already had gain much achievements ,we can see the future of wireless control system is in the ascendant.By plenty of studying and based on the working characteristics of the characteristic produced actually at the quay and mechanical equipment, this paper set up a monitoring system that can meet real production needings . The main study work of this paper is as followed :1) Analyzed the actuality and development trend of the mechanical equipment monitoring system , and proposed the research purpose and meaning of this paper.2) Set up the model of the wireless monitoring system of the quay , researched the basis o system framework of the monitoring system of the wireless LAN and analysed each functions, analysed that the electric wave of quay wireless communication propagates the characteristic, proposed the designing requirement of the systematic wireless communication .3) Analysed the characteristic and development of the wireless LAN , studied and analysed hardware making up and structure of the hardware and key technology of the wireless LAN of system and structures the wireless LAN of the monitoring system , writed the communication software , realized wireless terminal station andupward location machine data transmit.4) Against the characteristics of PLC and wireless terminal communication , researched the communication conditions of PLC and wireless terminal station, way of chaining , the passway and communication order of PLC and so on , writed the communication procedure on the wireless terminal station , realized reading and writing to PLC data of terminal wireless .5) Assigned to system hardware facilities , developed the man-machine interface of monitoring system of upward location machine , established the real-time database and historical database of the mechanical equipment state , realized the function of the display of the real-time contours of the location machine on the wireless monitoring system , the real-time warning and historical data inquiry and so on .Based on the summaries and conclusions of all research work, some suggestions and prospect for wireless Controlling system was put forward in the end.
