[0002] In the prior art, the ship safety net control system generally adopts a centralized control method in which the control panel is sequentially connected to the hydraulic pump station of the unit, the hydraulic distribution valve box, and finally connected to the hydraulic safety net. This control method has a complex structure, cumbersome installation and wiring, and consumes time and energy.
In addition, when a fault occurs in the centralized control system, all hydraulic motors need to be suspended for overall troubleshooting, which increases the time for troubleshooting and affects the operation of the overall system

The invention discloses a safety net control system. The system comprises a PLC (programmable logic controller), wherein the PLC is respectively connected with a control panel and a power supply; the PLC is also connected with a plurality of hydraulic power units; the hydraulic power units are connected with a hydraulic motor; the hydraulic motor is connected with a safety net; the hydraulic power units control the hydraulic motor to rotate in the positive and negative directions; the control panel adopts a liquid crystal control panel. The system is reasonable in structural design, has stable performance, adopts a decentralized system control mode, is convenient to operate and maintain, adopts the PLC to be served as a main controller, and solves the technical problem that the existing centralized layout and wiring mountation is complex.
Description
technical field [0001] The invention relates to a control system, in particular to a ship hydraulic distributed safety net control system. Background technique [0002] In the prior art, the ship safety net control system generally adopts a centralized control method in which the control panel is sequentially connected to the hydraulic pump station of the unit, the hydraulic distribution valve box, and finally connected to the hydraulic safety net. This control method has a complex structure, cumbersome installation and wiring, and consumes time and energy. . Moreover, when a fault occurs in the centralized control system, all hydraulic motors need to be suspended for overall troubleshooting, which increases the time for troubleshooting and affects the operation of the overall system. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a safety net control system with a simple structure and a high degree of integration i...
