| With the rapid industrial automation developing, the degree of automation inproduct line is enhancing step by step, thereof the efficiency also is increasing sharply,product quality is improving so much too. So the produced goods is so nice but cheap.Enhancing the degree of automation in plant can help company to become morecompetitive in the free market.This article is trying to introduce a part control system to collect each part inCar-manufacturing product line. The target is feasible, low cost, low error rate, andself-gnostic control system. The detail description is below. Mount a LED disp lay ineach part rack position. The LED display will indicate how many this part is need,hence operator knows how many this part he need to take, when complete, the sensorwill be shut down the LED so as to avoid to take it again. The main task as below:1). look up and research related documents, know well the developing situationin indoors and outdoors. Understand the research background and research benefit.2). Analyze the feature and advantage of CAN BUS, elaborate data-link layer andphysical layer in the CAN BUS layer structure, Message, Frame format, principle,feature.3). Design a completed control system based on CAN BUS network. Use VBlanguage to develop a operation interface in host computer. MSCOMM Serial Port isthe interface as communication with CAN node. Develop ACCESS database as systemdatabase.4). Build up the hardware and software for system.). Design the hardware forOperating System, according to each function module, develop it’s details, Systemfunction modules are: MCU function module, CAN controller and receiver module,MSCOMM module, Data display module. Design system software, use VB languageto develop Operating Interface, use to assembly language to software for CAN node5). Design and produce the PCB board, solder the each IC. Integrate systemhardware and software, Then complete system debugging and improve. |
