Abstract: A ship pipe routing method based on an artificial bee colony algorithm is provided, which relates to the technical filed of ship pipe planning. The method includes: step 1, simplifying expressions of devices and a layout space to build a mathematical model for a pipe routing problem; step 2, generating, by using a chaotic elite opposition-based learning strategy, elite initial solutions of the mathematical model for the pipe routing problem; and step 3, continuously updating, by using optimally guided employed bees, spirally searching onlooker bees, and scout bees, the elite initial solutions until a convergence condition is satisfied, to obtain a pipe coordinate solution. The efficiency of path planning and the quality of layout design are improved, and design costs are reduced.

Abstract: A drive circuit for a serial communications system is provided. The drive circuit may include a mode controller, a pre-drive circuit, and a main drive circuit. The main drive circuit includes multiple mode control switches and at least one pair of differential switches. The mode controller is configured to: generate a mode control signal, and transmit the mode control signal to the main drive circuit. The pre-drive circuit is configured to: convert a differential digital signal into a differential control signal, and transmit the differential control signal to the main drive circuit. The main drive circuit controls on/off states of the multiple mode control switches according to the mode control signal, and works in corresponding working modes. The drive circuit controls the states of the mode control switches in the main drive circuit, so that the main drive circuit works in different working modes.
