Unit connects central controller, and central controller is connected with plantwide control system.
As Figure 2-3, the high temperature resistant thing bit scan instrument 1 is arranged on the top of circular cooler trolley 4 by support 7, its
Scanning range is highly set to cover whole circular cooler trolley, shape and height for detecting solid accumulation；Central cooler is aided in
Controller 3 is placed near circular cooler trolley.Central cooler speed detector 2 is arranged on central cooler gearing friction plate.
As illustrated in figures 4-5, material thickness detecting device for sintering platform trolley 5 is installed on above the sintering car of board 6, for detecting sintering
Expect thick in machine trolley, and be sent to plantwide control system.
The high temperature resistant thing bit scan instrument uses model APM-3D level meter；The central cooler speed detector makes
With Patent No. ZL 2013.2.053698.8 speed detector, patent application day is on 08 22nd, 2013；Data are adopted
It is that I/O units use IBIL24AI4-PAC to collect unit；Central controller uses ILC470ETH1TX.
As shown in fig. 6, using the central cooler auxiliary control method of central cooler sub-controlling unit, comprising the following steps：
Step 1：Parameter preset is set in the central controller, and the parameter preset includes：Sintering pallet structure, sintering
