Optimize, described cabinet is standard 19 in2 U cabinet, described cabinet is directly installed in rack by hangers, described cabinet front portion is provided with described display control panel, described cabinet rear portion arranges gas nozzle and guiding gutter, draught fan, Ethernet interface and power interface, and described gas nozzle is connected with automatic fire extinguisher, and described guiding gutter is connected with described gas nozzle, described Ethernet interface is connected with described network communication module, and described power interface is connected with described power supply.
Described alarm linkage main control system connects upper control main frame by the Ethernet interface of network communication module.Network communication module by the warning of main control system, warning message according to protocol transmission to upper control main frame to realize remote detection.And when upper main frame undertaken arranging by network, control time, command adapted thereto is transferred to alarm linkage main control system by network communication module.
Fire extinguishing unit controls workflow of the present utility model is: if the electronic equipment breaking out of fire occurred in rack, rack automatically detects fire extinguishing system and starts, and first initializes, and detects fire detector and manual actuation of button state.If there is automatic or manual fire alarm signal, then judge whether it is manual command.Then perform this manipulation instruction immediately when being manual command, otherwise carry out delay wait.If have manual command within time delay, then carry out this manipulation instruction; Otherwise linking fire response will be started and start automatic fire extinguishing system.Complete at associative operation, fire alarm carries out system mode replacement, and carries out System self-test after removing.If the discovery system failure, then warn accordingly, postpone and enter timing after upgrading system display state to patrol and examine state.According to the given time interval, detection and manual operation are detected when patrolling and examining; If have, then enter handling procedure.Often reach in this course setting from the overhaul period, then start up system self-inspection and corresponding processing program.
The utility model has the advantage of: in units of the rack of the utility model in electronics machine room, carry out design for fire protection, fire extinguishing system is integrated into 19 inch rack of standard, and be arranged in rack, directly can draw the air in induction rack, thus greatly shorten the response time of detection; Simultaneously, the gas extinguishing agent sprayed also directly is released in interior of equipment cabinet, reaches extinguishing concentration required time far fewer than total flood fire suppression system, can not work the mischief to personnel in machine room, and the quantity of extinguishing media needed also greatly reduces, and reduces totle drilling cost and maintenance workload.
