Multifunctional safety control system for tower crane

Abstract

The multifunctional safety control system for tower crane possesses integrated several functions and is used for effective monitoring on tower crane for safe running. It consists of control circuit and system software. The control circuit consists of microprocessor module, sensor and signal processing module, relay module, keyboard and LCD module, and communication module. All the modules are installed inside one box, the sensor is connected through cable to the box, and the software has the embedded operation system muCOS-II as platform and multiple decomposed tasks for the whole system control.

Description

technical field [0001] The present invention relates to the application of electronic information intelligence technology in related fields of construction machinery, in particular to a multifunctional tower crane safety control system, which can realize the safety protection of tower cranes, real-time recording of working parameters, historical event sequence recording, load Anti-swing intelligent control, historical event playback, data communication and other functions. Background technique [0002] Tower cranes (tower cranes for short) are important equipment in industrial and civil building construction. They have the characteristics of high work efficiency, wide application range, easy operation, and easy installation and disassembly. In recent years, the rapid development of the construction industry has created unprecedented development opportunities for the development of tower cranes, but it also poses challenges. Tower crane safety accidents occur frequently with ...

Problems solved by technology

[0005] However, judging from the current domestic production situation, the intellectualization of tower cranes is still in its infancy.

As far as electronic limiters are concerned, although there are display devices, early warning signals, and good self-inspection functions, according to the survey, the current intact rate of electronic limiters only accounts for 34.7% of the survey samples, and the continuous work without failure is less than one year 81.4% of

The main problem of domestic products is the reliability problem. Under the premise of solving reliability, it is necessary to improve the performance of the whole machine and improve the system function.

On the other hand, most of the "black box" products currently developed in China use the 8-bit MCS-51 single-chip microcomputer system, which has very limited memory management capabilities and storage device capacity, and most of the functions are relatively single; most of them generally lack powerful data analysis. With the cooperation of software, the huge data display is not intuitive, and it is difficult to analyze the data in detail; moreover, the monitoring device that can combine the three functions of limiter function, safety monitoring and intelligent operation has not been reported in China.
