TBM pressure injection type concrete intelligent control system and control method thereof

Abstract

The invention discloses a TBM pressure injection type concrete intelligent control system and a control method thereof. The control system comprises a conveying pump, a local control system and a remote control system. The local control system comprises a local control cabinet, a local controller and a local display screen; the local control cabinet, the local controller and the local display screen are all connected to a CAN bus, the local control cabinet is used for controlling the conveying pump and collecting operation state data of the conveying pump, and the local controller and the local display screen are used for locally processing, monitoring and displaying the operation state data of the conveying pump and processing results of the operation state data; the remote control systemis connected into the CAN bus through a communication protocol converter, and the remote control system can collect and process data in the local control system, monitor and display the data and processing results of the data and remotely control the conveying pump. Free switching of remote and local operations can be achieved, the concrete pressure injection amount is accurately controlled, concrete injection is rapidly and efficiently achieved, and construction safety is guaranteed.

Description

technical field [0001] The invention relates to the field of TBM auxiliary control systems, in particular to a TBM injection concrete intelligent control system and a control method thereof. Background technique [0002] TBMs play a huge role in railway and road tunnels and water diversion projects. In the preliminary investigation and design of the TBM tunnel, it will be found that there are unfavorable geological conditions such as soft rock, large deformation and broken zone in the tunnel design route. These unfavorable geological conditions are the key points in the tunnel construction and safety risk control. Increase the risk of construction equipment damage and personnel safety cannot be guaranteed. On the other hand, when TBM excavates under adverse geological conditions, it is easy to cause various situations such as machine jamming and insufficient excavation reaction force, which affects the construction progress, increases engineering investment, and adversely a...
