and step 3: according to various gate state information acquired on the gate monitoring system software platform, a worker can reach corresponding instructions up and down on a control interface of the gate monitoring system software platform, wherein the instructions comprise gate lifting, gate lowering and gate stopping;
and 4, step 4: after the staff gives the instruction, the gate monitoring system software will record the operation, including the operation time, the operator and the specific action command.
