由我院设计研制、沈阳市无线电十九厂参加样机试制,并在辽宁省建筑设计院的配合下研制成功的“SJW19型火灾报警自动消防微机控制系统”在辽宁省建设厅的主持下,通过了技术鉴定。该系统采用相位选通原理实现报警信息的多点巡检、少线传送(用4根总线并联接入各火灾探测器取代了多线制系统中的n+2根信号连接线)。其理论正确,技术处理合
The SJW19 fire alarm automatic fire control computer control system successfully developed by our institute and researched and developed by the radio nineteen plants of Shenyang City participated in prototype trials and cooperated with the Liaoning Provincial Architectural Design Institute, under the auspices of the Liaoning Provincial Department of Construction. Technical appraisal. The system adopts the principle of phase gating to realize multi-point inspection of alarm information and less line transmission (with four buses connecting fire detectors in parallel to replace n+2 signal connection lines in multi-wire system). The theory is correct, the technical process
