In order to solve the problem that the connection between the host-side equipment and the client-side equipment is not close, which leads to the unclear display of industrial heritage, the research on digital protection and virtual display technology of industrial heritage is proposed. In this paper, on the basis of B/S architecture, the host-side platform equipment and client-side platform equipment are connected on demand. Then the virtual reality is used to determine the location of the user role, and establish the human-computer interaction mode, and then through the way of perfecting the database storage system, to realize the construction of the system software execution environment. The experimental results show that during the whole experimental process, the mean value of the contact tightness index between the host-side equipment and the client-side equipment of the experimental group is relatively high, while the mean value of the control group is relatively low. From the perspective of limit value, the experimental group, the ϖ. The maximum value of the indicator amounted to 35.5%, compared to the control group ϖ. Compared with the maximum value of 18.9%, it has increased by 16.6%.
