[Abstract]:In recent years, with the rise of various high-rise buildings and the improvement of production automation, tower cranes are more and more widely used in the construction process of modern buildings, and continue to develop towards the direction of large-scale and intelligent. In the aspect of large scale, the rise height, the amplitude of variation is more and more large, and the lifting weight is increasing, which puts forward higher requirements for the safety, reliability and efficiency of the tower crane. The rapid development of modern computer technology, sensor technology and wireless communication technology provides a technical basis for the development of tower crane safety protection device. To this end. Based on sensor technology, computer technology and measurement and control technology, this paper develops a real-time monitoring system for tower crane status, which makes it safer, more effective and more stable. On the basis of analyzing the working characteristics and safety monitoring requirements of tower crane, the paper discusses the monitoring methods of several parameters, such as hoisting height, lifting weight, amplitude, rotation angle, wind speed, temperature and humidity, and how to deal with these parameters. How to display. By means of shaft pin lifting weight sensor, incremental photoelectric encoder, absolute photoelectric encoder and wind speed sensor, the signal collection of the key parameters such as lifting weight, lifting height, vehicle amplitude change, rotation angle, working field wind speed and so on is completed. The parameter data can be transmitted to the ground remote monitoring center by GPRS wireless transmission mode. The users can know the status, working environment and geographical location of the tower crane in real time through the client software, and give an alarm to the illegal operation. It greatly facilitates the monitoring of the working state of the tower crane by the project supervisor. The ZigBee wireless network transmission technology is used in the communication. The protocol framework and network topology of ZigBee wireless communication technology are analyzed. It is determined that the tower crane anti-collision monitoring system adopts the netting mode of mesh network. Considering that the working environment of the tower crane is relatively bad and that there are many sources of interference, the photoelectric isolation technology, decoupling technology and filtering technology are used in the hardware circuit design to improve the reliability of the system, and the watchdog is used in the software design, Digital filtering and other measures to enhance the system's anti-jamming ability. Based on sensing technology, intelligent analysis technology, communication technology and information technology, the tower crane safety monitoring system is developed, which realizes the safety danger of tower crane structure and collision with obstacles. The cooperative collision hazard with multiple tower cranes can accurately distinguish and warn accurately, and can realize effective early warning and effective control, reduce and reduce the occurrence of safety accidents of tower cranes, and improve the efficiency of tower cranes. Based on the traditional mechanical and electronic sensors, this system is a new and reliable monitoring system for the working state of tower cranes, which combines the current digital processing technology, sensor technology and filtering technology. The system has good real time, reliability and wide application value. It is in line with the development direction of miniaturization and intelligence of tower crane monitoring system. Complete control function, rich monitoring function, stable performance, friendly interface and excellent performance-price ratio have achieved good results in field application.
