Abstract
The development of a digital twin virtual reality monitoring system for the hydraulic support group is the key to ensuring the safe and efficient operation of longwall mining face. Establishing a stable and reliable information processing channel to obtain information that is close to the actual working condition is an important link to ensure monitoring. Based on the prototype system of hydraulic support and the data of underground working conditions, an information interactive processing technology of software and hardware coupling is presented. The sensor’s real-time data is filtered by hardware and denoised by software based on empirical mode decomposition to obtain the most accurate working condition data. Relevant experiments were carried out under the conditions of information channels with various software and hardware filtering configurations. Comprehensive experiments were conducted from three aspects: the absolute posture monitoring test of hydraulic support, the virtual posture monitoring under the undulating floor, and the real-time sensing data driving and control under the virtual reality environment. The experiments show that the hardware and software-coupled filtering method can obtain reliable attitude data in real-time and ensure the effectiveness of digital twin virtual monitoring and control, which can offer technical assistance for the condition monitoring of mechanical equipment under complex working conditions.
