In an optical network having a terrestrial terminal and an open cable interface (OCI) connecting a submarine cable to a terrestrial cable, the OCI may include a filter positioned on an optical path between the terrestrial cable and the submarine cable and configured to pass first communication signals of a first frequency band, and filter out secondary signals of a second frequency band that does not overlap with the first frequency band. The secondary signals may be looped back to the terrestrial terminal. The terrestrial terminal may detect the looped back secondary signals, and in response, determine the presence of the OCI and that the supervisory signals were rerouted by the OCI.

The present invention relates to a four-motor electromechanical composite transmission device for a tracked vehicle, comprising an engine and two dual-motor drive systems symmetrically arranged on both sides of the engine, the two dual-motor drive systems respectively corresponding to driving the track mechanisms on both sides; two variable-speed planetary gear mechanisms are connected to both ends of the engine, and the two dual-motor drive systems are respectively coupled to the engine through the variable-speed planetary gear mechanisms; a differential planetary gear coupling mechanism is arranged between the two dual-motor drive systems, and the two dual-motor drive systems are coupled to each other through the differential planetary gear coupling mechanism. The present invention adopts a symmetrical structural arrangement as a whole, and the motor, variable-speed planetary gear mechanism, reduction planetary gear, fixed-axis gear reduction mechanism, and two-speed variable-speed planetary gear mechanism are all symmetrically arranged, with simple structure and process, which is conducive to the spatial arrangement of the whole vehicle. At the same time, steering power reflux can be achieved, which can not only reduce energy consumption but also reduce the power level of the motor.

This invention provides an electro-hydraulic parallel drive system for engineering machinery, comprising a mechanical transmission section, an electric drive section, a hydraulic drive section, and a walking execution section. The mechanical transmission section includes a power input shaft, a hydraulic input shaft, a power output shaft, a first transmission shaft, a second transmission shaft, a third transmission shaft, a fourth transmission shaft, a fifth transmission shaft, a sixth transmission shaft, and a seventh transmission shaft arranged in parallel with each other. This invention combines the advantages of electric drive systems and hydraulic drive systems, using both electric and hydraulic drive sections to jointly drive the machinery, thus leveraging the advantages of the good speed regulation performance of electric transmission and the high power density of hydraulic transmission. This results in relatively low energy consumption, sufficient driving force, and good economic efficiency.

The present invention relates to a dual-motor coupling transmission device for a tracked vehicle, comprising two electric drive mechanisms and a fixed-axis gear reduction coupling mechanism arranged symmetrically, each electric drive mechanism correspondingly driving one track mechanism; the electric drive mechanism comprises a motor, a speed change mechanism, and a single planetary gear coupling mechanism which are sequentially connected in transmission; a double planetary gear differential coupling mechanism is arranged between the two motors, one end of the output shaft of the speed change mechanism is connected to the single planetary gear coupling mechanism, and the other end is connected to the double planetary gear differential coupling mechanism; the output shafts of the two speed change mechanisms are coupled through the double planetary gear differential coupling mechanism; the two ends of the fixed-axis gear reduction coupling mechanism are respectively coupled and connected to the two single planetary gear coupling mechanisms, and at the same time, the middle part of the fixed-axis gear reduction coupling mechanism is coupled and connected to the double planetary gear differential coupling mechanism. The present invention uses a multi-planetary gear transmission mechanism as a power coupling mechanism, changes the power flow direction in the transmission system by adding a mode switching mechanism, and at the same time regulates the motor, so as to realize the precise control of the output power of the track wheels on both sides, and achieve the effect of small radius steering and center steering during high-efficiency travel.
