电子工业部六所为北京市公安局研制成功了一套点对点的交通信号传输处理系统。这套系统与一般数传系统相比较,其独特之处在于采用了Motorola公司的MC6860低速调制解调器芯片,并以MC6850和MC6860为核心,配置必要的附加电路自成一块独立的数传模板。整个系统结构紧凑,灵活,易扩,体积小,重量轻,使用维修方便。经现场运行证明该系统性能稳定可靠,各项指标均可满足用户要求。现对该系统介绍如下。
Six of the Ministry of Electronics Industry successfully developed a set of point-to-point traffic signal transmission and processing system for Beijing Public Security Bureau. The system compared with the general data transmission system, the unique feature is the use of Motorola’s MC6860 low-speed modem chip, and to MC6850 and MC6860 as the core, configure the necessary additional circuits form a separate data transfer template. The entire system is compact, flexible, easy to expand, small size, light weight, easy to use and maintenance. The field operation proved that the system performance is stable and reliable, the indicators can meet user requirements. The system is introduced below.
