Embodiment 1

[0061] In the example, set the excavation mode of multi-footage and multi-layer single truck, select the target parameter under automatic dredging control, set the traverse speed to 13m / min, each step of the trolley is 1.5m, and the depth of each layer is 1.5m. Other setting parameters related to traverse speed control are shown in Table 1. Using this method, the recorded working data is shown in Table 2 below:

[0067] Note: Process 1 is mining the first layer, process 2 is mining the second layer, and process 3 is mining the third layer.

[0068] It can be seen from Table 1 that the traverse speed is accurately controlled at the set value.

[0069] In this construction example, the sideline deceleration and other functions are verified, and the contro...

Embodiment 2

[0073] Set the excavation mode of single-layer multi-footage single truck, select the automatic dredging control function of the target output, and set the automatic control parameters as shown in Table 4 below:

[0074] Table 4 Target output automatic control parameter configuration table

[0075]

[0076]

[0077] In Example 2, according to the setting parameters in Table 4, the control function was verified, mainly verifying the response of the control system at each stage. The control function verification table is shown in Table 5 below:

Abstract

The invention relates to a yield-based automatic dredging control method of a cutter suction dredger, and belongs to the technical field of automatic control of engineering ships. According to the yield-based automatic dredging control method of the cutter suction dredger, four automatic dredging functions of automatic target parameter, automatic target yield, automatic maximum yield and automaticeconomic yield are achieved according to construction requirements. In order to realize any function, one of three automatic dredging modes of single-layer multi-footage automatic mode, multi-layer multi-footage automatic mode and multi-footage multi-layer automatic mode can be manually selected. In each mode, control parameters are firstly set, and then a rimer, a traverse-moving winch, a bridgewinch, a steel pile trolley, a mud pump, a vacuum release valve and the like are jointly controlled to operate in different sequences to realize the automatic dredging operation of the cutter suctiondredger, and high and stable yield of automatic dredging is achieved. According to the yield-based automatic dredging control method of the cutter suction dredger, the labor amount of dredging operators can be greatly reduced, the operation difference between different operators is reduced, the construction quality is improved, the safety of equipment is ensured, oil consumption is reduced, and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of engineering ship automation control, in particular to an output-based automatic dredging control method for a cutter suction dredger. Background technique [0002] After the 1990s, with the development of computer and network technology, the "whole ship integrated monitoring system" of dredgers has been gradually applied. Construction personnel can control the dredging equipment and monitor the dredging process through a remote workstation. This significantly improves the construction efficiency of dredgers, but the operation level and proficiency of dredging operators will greatly affect the construction output of dredgers. At the same time, there are also problems such as high labor intensity, low equipment safety, and relatively high fuel consumption. [0003] In order to solve the above problems, it is of great significance to invent a production-based automatic dredging control method for cutter su...
