Based On The Can Bus The Rapier Monitoring Network Systems Research And Development

The textile industry is one of the fundamental industries in China. Today China has become the world's largest producer of soft goods with its enormous quantity and productivity. But the old facilities, out-time management and inefficiency in this field have limited its advancement with the more and more competition in the world's textile market. Thus it is vital important to promote the capability to produce and apply the high-tech textile machine in China.This paper mainly use the net technology, the CAN Field Bus technology, the parallel communication technology and the VB language to reconstruct the common weave enterprise. We have designed the network supervise system which based on the DSP and CAN Field Bus. With the system, you can Real-time supervise the running state of all the spin machines, and you can choose to all-mode or single-mode supervise, give the spin machine run or stop command. All the pertinent data will be write down by the system. The management of the enterprise will become so easy. This paper mainly includes as follows:1. Analyze the development trend of the Field Bus technology, the advantage of the Field Bus compared with the other technology. Also discussing the status of DSP in the modern industry and the relationship of DSP and the Field Bus.2. After an investigation of the current condition of the producing management of China's textile industry and analysis of a lot of practices, the author provide a FieldBus Net based on the CAN to establish an automatic control system for the producing management of the weaving factory, and also provide a structure chart of the model of the whole control system.3. To realize the real time supervision and management of all sub-machines, there is a series of system control software written with the Microsoft Visual Basic tool to run in the principal machine. The control system including the general control module, communication module, supervision module, data module and producing management module etc.4. There is one communication agreements designed here, which including the data exchanges protocol between the principal machine and the sub-machine. There is parallel-communication between CAN and computer.5. To form a typical C/S and B/S system on the Intranet of the company in order to make benefit for company management, reduce the cost of production and improve the productivity.6. The author did a number of tests of the control system and the software run by the principal machine in many ways, analyzed the results of the tests, and gave the direction for improvement.
