A Filter Receiving Machine System Based On Fieldbus

With the development of manufacturing and the need of the way of manufacturing settlement, it is inevitable to have the filters' depletion amount and ensure the depletion data. Complied with the requirements of manufacturing policies, combined with the developing industrial automation and computer network, relied on ripe data processing system, in this paper the filter receiving machine system in the Hongta Tobacco Group is introduced. In this paper the following points are mainly stated and concentrated on: data collection and concerning information of Fieldbus; the combination of the whole system and its realization; the whole planning of the system and the software development and its installation and debugging. Further more, in this paper the following problems are solved: how to count filters exactly with the help of PLC and the testing system; how to deal with the amount of filters and give a report about filters' exact depletion with the help of computer and its net. After testing, the system runs well. The range of error is between 0.38 ten-thousandths negatively and 0.56 ten-thousandth positively. The precision of designing reaches 5 ten-thousandths and gets a good on-the-spot demonstration of information processing.
