| Abstract: | In order to change the deficiency and limitation of traditional control net, which adopt RS232-RS485 conversion within host-computer and interface statement ,and adopt RS485 conversion within each node, this paper brings forward a new, low cost alterative means of CAN net, which do not alter inherence communication protocol. The article analysis the characteristics and the functions of the slice and the protocol conversion in detail and then introduce the work principle and soft-andhardware design. This design have high-grade vivid with adaptability. |
