Problems solved by technology

Once the computer equipment is damaged or the network system crashes, it will cause the dredger to not work normally, and even cause equipment safety accidents
Because in the existing monitoring system, the functions of the workstations are relatively independent, it is difficult to replace each other, and the redundancy performance is low

Embodiment Construction

[0010] figure 1 The integrated dredging platform management system for trailing suction dredgers based on redundant networks shown in , uses two ring networks, the bottom ring network 1 is responsible for bottom data collection, the top layer ring network 2 is responsible for upper layer data monitoring, and data exchange at the field bus layer The data exchange with the monitoring layer of the computer workstation is independent and separated. Each ring network includes at least three network switches. The switches are industrial-grade network switches with at least 2 groups of optical fiber interfaces and 2 RJ45 interfaces. The optical fiber interfaces are ST or SC. , RJ45 interface is 10Mb / 100Mb adaptive, with independent IP, DC24V dual power supply, with alarm output, DIN rail installation, working temperature at least -10 ℃ ~ 65 ℃. The number of switches depends on the number of PLCs, gateways, and workstations.

[0011] A total of three servers are connected between the...

Abstract

The invention relates to an integrated platform management system for the dredging of a trailing suction hopper dredger, in particular to an integrated platform management system based on a redundant network. The system comprises network switch, a server, a plurality of workstations, a PLC and a gateway which are respectively connected with a bottom ring network, and a top ring network; the PLC is used for realizing the control on the input and the output of field-working devices of a dredger, the gateway is used for realizing the conversion between the third protocol and the TCP / IP protocol, the PLC and the gateway are respectively connected with the bottom ring network through the network switch; the workstations for managing and monitoring data are connected with the top ring network through the network switch; and the server is connected with the bottom ring network and the top ring network through network switches arranged on the bottom ring net and the top ring net. The invention realizes the full sharing of the whole ship information resource and improves the system reliability.

Description

technical field [0001] The invention relates to a dredging comprehensive platform management system for a trailing suction dredger, in particular to a redundant network-based dredging comprehensive platform management system for a trailing suction dredger. Background technique [0002] For trailing suction dredgers, the number of sensors is huge and there are many types of equipment. In addition to conventional ship equipment such as main engines, generators, and steering gears, the monitoring system also has a large number of dredging equipment, such as mud doors, gate valves, butterfly valves, and A-frames. , rake pipe, these equipment are distributed in the deck surface, both sides, engine room, pump room, auxiliary equipment room, watertight cabin, driving cab and other parts of the dredger. The existing monitoring system needs to lay a large number of cables in order to collect and monitor the signals distributed in various places of the ship, which takes up a lot of sp...
