Title:
INTELLIGENT CENTRALIZED CONTROL SYSTEM AND METHOD FOR TUNNEL CONSTRUCTION BLASTING AND EXHAUST
Document Type and Number:
WIPO Patent Application WO/2023/165633
Kind Code:
A1
Abstract:
Provided are an intelligent centralized control system and method for tunnel construction blasting and exhaust. A monitoring unit and a first programmable logic controller are both located on an operation device for tunnel construction blasting. The monitoring unit is in communication connection with the first programmable logic controller. The monitoring unit is used for collecting environment data of tunnel construction blasting and sending same to the first programmable logic controller. According to the collected environment data of tunnel construction blasting, the first programmable logic controller determines, on the basis of a preset logic relationship, whether to send a control instruction (S101). If the environment data satisfies the preset logic relationship, the first programmable logic controller sends the control instruction; a second programmable logic controller is located at an end of the tunnel and is in communication connection with the first programmable logic controller and an exhaust unit. In response to the sent control instruction, the exhaust unit installed in the tunnel is controlled to perform frequency conversion operation, so as to exhaust dust in the tunnel (S102). Thus, high-precision unmanned management and control of tunnel construction can be realized.
