Collect processing system and use Modbus TCP communication interfaces.
The beneficial effects of the utility model are：Using distributed optical fiber temperature measurement technology, a large amount of point sensors can be replaced,
Realize covering, monitoring that can be real-time to coldplate, and abnormal coldplate can be accurately positioned comprehensively；Avoid traditional scheme because
Difficult wiring caused by monitoring point is excessive, the problem of networking workload is big, distributed temperature measuring optical fiber physical life length, reduction length
Phase maintenance cost, and not by various electromagnetic interferences, the stability of guarantee temp measuring system.
The abundant monitoring software of distributed optical fiber temperature measurement main frame matching function, the thermic load of monitoring hot-blast stove can be presented in real time
Space layout figure, shows the real time temperature currently gathered, and carries out characterization, shows the current amount of each loop alarming index
Value；Coldplate abnormal alarm can be carried out, is required to set abnormal alarm value according to user, and monitored hot-blast stove can be cooled down
Plate space sets different subregions by section, and the monitoring of various criterion is carried out to different positions；Settable multistage absolute temperature alarm
With the alarm of the multistage temperature difference, or both combinations, wrong report is substantially eliminated；Alert locations can be accurately positioned, and record alarm number
According to；Fibercuts alarm can be carried out, when fibercuts alarm occur and show fracture position, but because temperature-measuring optical fiber is used
Looped network is laid out, even if generation optical fiber is graceful, can't influence the operation of temperature-measuring system of distributed fibers.
