Abstract:Aiming at the problems that the measurement accuracy is low and the stability is poor of the traditional two dimensional measurement system, we proposed a method of 3D virtual dynamic measurement based on data interaction. This method adopted the working mode of the synchronous coupling of the three dimensional configuration and bus technology. We studied the key problem of the model driven system in 3D measurement system, discussed the feasibility of data interaction in 3D measurement system, and applied this method to coal mine drainage system. Experimental results show that the 3D virtual dynamic measurement system realized by this method has the advantages of stable operation, simple operation, high reliability, and wide application prospect.
