Abstract


Tower crane (tower crane for short) is the most important industrial and civil construction, material handling machinery, as the socio-economic development, its application will be more and more widely; engineering practice shows that the safety performance of the tower crane has become a threat to buildings The big problem of workers' lives and property of the State, thus real-time monitoring and management of the tower crane running state significance. The sub-topics of the topic is based on the national \This article is a pre-the tower mechanic condition parameters data acquisition system of the project development. Real-time and accurate collection of the tower mechanic condition parameters critical to the effective monitoring. Research and reference of the existing tower mechanic conditions parameter data acquisition system based on the proposed use of the microcontroller as the core components of the control system, the development of a new generation of multi-functional tower mechanic for the problems of the existing data acquisition systems, The condition parameter data acquisition system. Tower the machinist conditions parameter data acquisition system process point of view of the tower crane, lifting height, weighed for testing. According tower crane weighing process, angle, height detection principle angle sensor used for the tower the machinist conditions parameter data acquisition system, height sensor, load cell selection, and to determine the installation position of the sensor. Selection of AT89C52 chip the tower the machinist conditions parameter data acquisition system hardware design aspects, the system CPU, the chip built-in eight central processor and 8KFLash of the storage unit, suitable for tower crane working on-site complex control situations; dot-matrix liquid crystal display angle tower crane work process, known as weight lifting height and other real-time display provides the operator with an intuitive display interface; DS1302 clock chip clock design, record the time information in a different state, easy accident inquiries ; circuit system with voice alarm, voice alarm in the tower crane danger; addition to the tower the machinist condition parameters acquisition system design data storage module with a \will tower crane data and status information stored in the data storage module, convenient accident analysis. The modular design concept in terms of software design, the C51 language programming. One by one the tower mechanic conditions parameter data acquisition system, the main program, A / D conversion and calibration module, dot-matrix liquid crystal display module, clock module and various functional modules specific software design and implementation, and gives the corresponding flowchart; final optimization of the entire software system. Tower crane working environment is more complex, there is a lot of interference nearby. This article in the the tower mechanic condition parameters acquisition system design and debugging, combined with the actual anti-jamming design from hardware, software, printed circuit board wiring. The tower the machinist conditions parameter data acquisition system debugging results show that the the tower mechanic condition parameter data acquisition system developed a good run, the real-time acquisition and display system is scheduled lifting height, angle, said weight, time and other information, and voice in the tower crane danger alarm.
