and identifying the car number of the torpedo hot metal mixer car reaching the designated position through a car number identification probe to judge whether the torpedo hot metal mixer car is matched with the tank number information or not, and automatically connecting the torpedo hot metal mixer car during matching to prepare for tapping operation.
10. The process method for realizing automatic backward flow of the torpedo type hot metal mixer car as claimed in claim 9, wherein the treatment of the hot metal mixer car, the torpedo ladle and the hot metal ladle after tapping is specifically as follows:
when the weight of the molten iron tank reaches the target weight, controlling the torpedo tank to rotate to zero, storing and analyzing the molten iron use condition in the torpedo tank, and if the torpedo tank is empty, transporting the torpedo tank out of the station through a torpedo car; if the torpedo ladle is not emptied, the control device responds to the production scheduling request to replace the hot metal ladle so as to call the torpedo ladle which is not emptied currently to provide molten iron for the corresponding hot metal ladle;
when the weight of the molten iron tank does not reach the target weight and the molten iron use condition in the torpedo tank is analyzed to obtain that the molten iron is emptied, controlling the torpedo tank to rotate to zero and waiting for the subsequent torpedo tank to discharge iron;
when the transport locomotive pulls the torpedo cars to exit, if the subsequent torpedo cars wait to the preparation position, the rolling door is controlled to be kept open, so as to allow the subsequent torpedo cars to directly enter the back-flow station for tapping operation.
