| Abstract: | An industrial Communication system--intelligent non host machine explosion proof sound amplification talk back system is researched.This system is especially useful in flammable and explosive working places in production enterprises of petroleum,chemistry,metallurgy,medicine and coal,which have large range room and strong noises.Based on the design of system structure,the hardware and software are designed,the transmission format of the olcal feed junctor signaling is given out and the configuration theory of explosion proof local feed junctor shared by multiple channel is researched.The antijamming measures are adopted in two aspects of hardware and software and designed with explosion proof. |
