General Situation of blast furnace station, the indoor and outdoor project of microcomputer interlocking system for blast furnace station of Xinggang is the general contract of Beijing Hollysys Company, the interlocking system adopts the computer interlocking system of HS2000 VSI three to two signals, the monitoring system adopts SmartPro RSS Microcomputer Monitoring System, integrated dispatching monitoring system and TV monitoring system. In line with the Railway Ministry TB 10007-99"Railway Signal Design Code" , TB / T3027-2002"computer interlocking technical conditions" , TB 1774-86"relay electrical centralized interlocking technical conditions" , TB / t 2496-2000"signal microcomputer monitoring system technical conditions" . There are 20 sets of interlock switches, 36 signal machines, 36 track sections and 4 crossings in the interlock zone. 2. 2.1 interlocking equipment: Railway signal adopts one set of HS2000 VSI three-take-two-fault-tolerant computer interlocking system, and one main cabinet. 2.2 power supply equipment: microcomputer interlocking central station power supply panel set of 3 panel, 10KVA. 2.3 interface equipment: 3 Interface Cabinets. 2.4 operator station: CRT Station Monitor 1, of which 1 is spare, station control special industrial keyboard, mouse, trackball. 2.5 dispatching supervision system equipment a set of 2.6 monitoring stations: including the function of history station and electric maintenance station, adopting SmartPro RSS microcomputer monitoring system, including 1 CRT Station Monitor, 1 printer and related operating equipment. 2.7 Indoor interlock control equipment and network cable. 2.8 outdoor signal machines, electric point machines, track circuits, and cable networks. 2.9 A bevision monitoring system, including 3 monitoring points, integrated into the signal building unified surveillance. 3. The working principle of HS2000 Vsi three-to-two railway signal computer interlocking system, the status of on-site equipment in the central interlocking area of Xinggang blast furnace station, the LOCAIION or reverse POSTTTION of the turnout, the closed or open state of the signal machine, the idle or occupied status of the track circuit section, and the status inbation of the crossing is sent to the corresponding interface cabinet through the inbation channel cable line, the interface circuit of the interface cabinet sends the above-mentioned inbation to the three-off and two-off fault-tolerant computer in the working state by the double-break bbbbbb after the electrical conversion, and the computer carries on the logical operation to the above-mentioned inbation and displays it on the CRT screen after the processing, for the signal duty officer to keep a bbbbb understanding of the situation on site. When the signal duty officer needs to arrange the route or carry out other operations, use the keyboard or mouse to send the operation command to the three-to-two fault-tolerant computer, the computer analyzes the operation command and makes logical calculation and confirms that it can be executed, a Control Command is issued, which is sent to the scene through the interface cabinet and the inbation channel and is executed. The new state of the controlled device is displayed on the CRT. When the computer logic operation is not satisfied, the new state is not executed, and the corresponding reason is given on the CRT screen. HS2000 VSI system has multi-layer structure, all function layers communicate through standard interface, some equipments of dispatching and operation belong to non-safety equipments, and some equipments of interlock control and outdoor belong to safety equipments.
