Port Crane Structure Wireless Remote Online Monitoring Of Data

Port as a gateway to foreign trade, with economic development, and gradually speed up port construction, port equipment which require higher and higher, port machinery and equipment toward the large-scale, high-speed, automation and intelligent direction, port machinery features more complete, but the structure is more complex, which also implied an increase in security issues.The traditional method of testing the crane is regularly monitored by the Quality Assessment Centre technical staff to implement field testing cranes. port equipment, large-scale structure, testing agencies are tens of meters from the ground, and the quality and technical personnel also need to bring a lot of testing equipment, even if thus, the state was only detected cranes to stop the operation to be detected only in this moment, can not fully explain the period since the crane safety conditions.The development of online monitoring system, real time online on port cranes to monitor the changes in the metal structure of the stress on the crane in which the state judge, on the possible sudden failure to stop the operation or maintenance instructions recommended. Online system for crane metal structure on the real-time online monitoring, the statistical study of monitoring data on the future design of the crane structure is also helpful.This paper is mainly to solve the real-time online monitoring system for remote transmission of data problems. The main contents are as follows:(1) Based on the harbor mechanical device unique feature, uses the optical fiber Bragg diffraction grating to take the sensor gathering data, has made the exhaustive analysis to the light Bragg diffraction grating model as well as the sensing principle, the union harbor hoist crane characteristic, makes the design to the sensor node arrangement as well as the modulation demodulation system, then the basis gathering data parameter characteristic, has formulated the sensor network topology, in view of the harbor transmitting range demand,802.11 as well as the transmission base depot has done the corresponding research to the wireless transport protocols.(2) In the GSM network foundation, conducts the exhaustive research to the GPRS network architecture as well as the network protocol.To various connections function, the agreement as well as the data which increases in the GSM network architecture flow to conduct the thorough research, has drawn up the network transmission structure horizontal plan, several kind of network plans as well as the system actual demand which the union network supplier provides, the formulation wireless network plan.(3) In the previous analysis, based on the realization of the wireless terminal DTU hardware and software development, through dial-up Internet access, access to GPRS network connection port wireless terminals, remote transmission of data. And the system functions and system processes are analyzed by the study to learn Visual Basic language, remote transmission of data visualization.
