The Research On Dynamic Weighing System Of Conveyer Belt Online

Produce, build, transport, trade, science and technology and daily life can not be imagined without weighing. With the progress of the industrial automation and modernization of management, the way of weighing has changed from traditional lever machinery type to digital intelligence weighing; especially the fast dynamic weighing has substaintially developed. However, our country little complete function products, improve existing to weigh device, develop and study multiple functional dynamic weighing system is imperative.This article elaborated a set of new dynamic weighing system of conveyer belt designed independently based on LabVIEW. The overall organizations of the weighing part and the weighing method have made the significant innovation, relatively fixed transmission conveyer belt part had the certain cushion to the material impact function, enhanced the survey accurate and the stability, moreover, the organization was designed simple, the sensor installment was convenient. So this system is suitable in the real-time measurement on the massive materials transmission by conveyer belt.This article has made the theoretical analysis on the construction of the dynamic weighing system, the system model and its principle of work firstly. Then it has specifically analyzed the hardware and the software design, as well as data processing algorithm and its software procedure design. This system could realize the data gathering through the weighing sensor and complete the data processing and the demonstration and so on based on the software. The part of hardware emphatically introduced the weighing sensor, the electrical machinery and the data acquisition system. We applied the system parameters' estimation and product divides two methods to recognize the data processing. The system software is LabVIEW, which has widespread application present as test software based on the graph language programming. This software can take thedemonstration and the correlation function realization easily. Finally, we correctly analyzed the error source of the system and gave the means of improvement. This will improve the system for later and provide the very good experience.Compared with the traditional weighing system, this weighing system has the quicker speed and the higher accuracy precision. It's installing and debugging are more convenient.It is also easier to realize the intelligent control. These advantages make it have wider market potentials.
