In view of problem of unsatisfactory effect of traditional training for coal mine full-hydraulic drilling rig, a training system for coal mine full-hydraulic drilling rig based on virtual reality technology was developed. The system is consisted of lower computer and upper computer, and communication between the lower computer and the upper computer is realized through FX2N series PLC programming interface. The lower computer uses PLC to collect and process control instruction of drilling rig virtual console. The upper computer applies Quest3D virtual software to realize virtual drilling rig and scene setting, key parts virtual disassembly and virtual drilling rig operation programming. The system shortens training period and reduces training cost with good human-computer interaction performance and simple operation.

In view of some problems of video monitoring of shearer and two-dimensional plane monitoring such as blurring monitoring images, inability to display running status of shearer real-timely and so on, a kind of remote monitoring system of shearer was put forward which was based on PLC and Quest3D. The system uses PLC, computer, remote console and others to compose hardware platform, uses Quest3D software to realize virtual monitoring platform, and realizes communication between software and hardware by data interface of virtual reality and FX2N PLC programming port. The test result shows that the system can realize real-time display of running status parameter of shearer and remote control of shearer.

In view of problem that current training methods for shearer operation can not show three-dimensional operation process of shearer from multi-angle, virtual training system based on Quest3D was designed. The system consists of lower machine and host machine, and they communicate via RS232 protocol. Lower machine is used to simulate control platform of shearer, and the control circuit taking STC89C52 microcontroller as the core realizes receiving, processing and transmission of external operation signal. Host machine uses 3DMax modeling software to create required model of virtual scene, builds virtual scene by Quest3D three engine development platform, and controls the model according to order of the lower machine. The system implements virtual training function of shearer, shortens training cycle, and reduces training cost.

The application and influence on landscape increased broadly. Quest3D is one of the important software to realize the virtual reality technology, taken a design of classical courtyard as an example and developed landscape roam system combined with Quest3D, and the advantage and disadvantage of Quest3D were described from the aspects of the selection of Quest3D technology and software and hardware the establishment of basic process.
