Abstract


With the rapid development of computer , communication and network technology , industrial communication technology is moving in the direction of intelligence and network development. As in recent years , the rise of the short-range wireless communications technology , wireless communication technology is gradually penetrated into the field of industrial monitoring . This paper analyzes the limitations of traditional wired communications networks and wireless communication technology advantage , to guarantee real-time industrial field , and reliability requirements of the premise , the study of the characteristics of the the MODBUS protocol stack family based industrial MODBUS protocol wired / wireless hybrid network transmission scheme , design the hardware and software of the gateway , MODBUS protocol , provides an effective way for the industrial data , wired / wireless network hybrid transmission links and transmission in wired and wireless networks , seamless has broad application prospects . The completed work as follows : ( 1 ) analysis and study of the deficiencies of the traditional wired communications networks , combined with wireless communication technology , this paper proposes a hybrid wired / wireless network transmission scheme . (2) in-depth study the MODBUS protocol suite , based on MODBUS protocol wired / wireless hybrid network gateway model , designed to achieve the program 's wired / wireless protocol translation gateway . ( 3) new wall materials production line applications as the background , under the premise to ensure the industrial field reliability , real-time and cost , system analysis and program selection , the RS-485 bus for wired communication , ISM RF chip technology is used to wireless communication. (4) carried out a detailed introduction to the realization of wired / wireless gateway from the hardware and software perspective . Hardware the gateway hardware system architecture and chip models , both to meet the design requirements , but also cost savings ; software , the entire system of software modules developed by C language . (5) industrial wired / wireless gateway performance testing and results analysis . By wired and wireless communications test to verify the reliability and stability of the gateway , to provide a basis for the application of the actual scene .
