Abstract

A test bench for testing a shield machine control system comprises a shield machine function simulation system and a sensing device arranged in the function simulation system, wherein the sensing device is communicated with the shield machine control system to be tested, and the function simulation system can be a physical simulation system, a mathematical simulation system or a combination of the physical simulation system and the mathematical simulation system. The test bench for testing the shield machine control system can completely simulate various functions of various types of shield machines, so as to test the correctness of the shield machine control system in design, assembly and debugging, avoid the risk arising from direct communication with the shield machine when the design of the control system is faulty, and shorten the circle of developing a new machine. Meanwhile, the invention is helpful for optimization and modification of the shield machine control system and remote fault diagnosis on the shield machine operated in a tunnel.

Description

technical field [0001] The invention belongs to a simulation test device for the function of tunnel excavation engineering equipment, in particular to a detection test device for a control system of a shield machine. Background technique [0002] The shield machine is a large-scale equipment with a relatively complex structure. To manufacture a shield machine with good performance, the research and development of its control system is very important. Researchers will invest a long time and a lot of energy in the research and development of the control system. However, there will still be some unreasonable parts in the design, and these unreasonable parts can only be known when the control system is connected with the actual actuator of the shield machine and the construction is carried out; this not only brings the construction Hidden dangers also delayed the progress of the project, so it is imperative to develop a device that can detect the correctness of the control syste...
