The Research Of Condition Real-Time Monitoring System Of Toewr Crane Based On Embedded Technology

Tower cranes are major hoisting apparatus of the industrial or civil construction with traits of high working efficiency, wide range of uses, easy manipulation and convenient installation or dismantlement. With the development of the architecture industry in recent years, tower cranes are offered the best opportunities for developing which they have never met. But when the number of tower cranes in creases rapidly, the number of the tower-cranes accidents also increases in large quantity. Therefore it is urgent that the safety of tower cranes should be improved and the rate of tower-crane accidents should be reduced. To realize the goal this paper presents a sort of real-time monitoring system of tower cranes, which is developed on the basis of sensor technology, embedded technology, measuring and automation control technology. The system can ensure that cranes work more safely, more smoothly and more efficiently.In this paper, the main task of the research is to develop the real-time monitoring system of tower cranes based on embedded technology and to perform the hardware and software design. The embedded microprocessor unit is selected as the core of the real-time monitoring system. This system uses embedded technology and field bus technology—CAN. The research work of the dissertation include mainly as follows:1. According to the current status, running status and working environment of tower cranes, the subject formulates the overall design plan of the tower-crane monitoring system.2. According to the general scheme, the main controller is designed based on 32-bit ARM microprocessor (LPC2292), and the realization of the main circuit modules is described in detail.3. The subject designs a distributed data acquisition network system and uses the data communication capabilities of CAN field bus. 4. To compose the communication procedures of filed bus, data collection procedures and the user application procedures for task module.5. Finally, the subject fulfills the debugging work of hardware and software for the tower-crane monitoring system based on embedded technology.
