Operation recording device of port gate seat type crane and performance assessment method

The invention relates to an operation recording device of a port gate seat type crane and a performance assessment method; the operation recording device consists of four parts of a sensor, a driver operation signal acquisition device, a signal conversion circuit, a main controller circuit and I/O equipment. A sensor signal enters a main controller; and a user realizes human-computer operation by a digital keyboard, a liquid crystal display and an IC card. The performance assessment method aims at the mechanical operation flow of loading and unloading bulk cargos of the port, catches an action signal and a rotary angle of the main controller and a weight sensor signal, judges the integrity and the effectiveness of each operation of a drive in real time and records the finish time and the effectiveness of the action of each operation. The operation recording device realizes the metering of the operation quantity of the operating driver, provides scientific and accurate data for the performance assessment of th
