【摘要】 研究一种用于石油、化工、冶金、医药、煤炭等行业中易燃、易爆、大范围、强噪声的生产场所的工业通信系统———智能型无主机防爆扩音对讲电话系统。在系统结构设计的基础上 ,设计了硬、软件 ,编制了软件 ,给出了绳路信令的传输格式 ,对多信道共用的防爆绳路配置理论进行研究 ,从硬、软件两方面采取了抗干扰措施 ,并进行了防爆设计更多还原

【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.更多还原
