Virtual reality system and method for nuclear fuel reprocessing plant head end

Abstract

The invention belongs to virtual reality technology, and particularly relates to a virtual reality system and method which can economically and truly simulate mechanical operation environment of a nuclear fuel reprocessing plant head end. The system comprises a server, a model processing unit, a data acquisition unit, an I / O data exchange transmission unit, display units, a touch screen and a virtual peripheral; the operation control instructions of the touch screen and the virtual peripheral are transmitted to the model processing unit through the data acquisition unit and the I / O data exchange transmission unit, the model processing unit carries out model optimization and action setting, and transmit and display the processed model data which are processed again through the server in the display units; the display units comprise a two-dimensional display unit and a three-dimensional display unit, and the display method of two and three dimensional integration has strong immersion and more accords with the real work condition. The virtual reality system and method for the nuclear fuel reprocessing plant head end has the advantages of being smart, convenient and fast, good in economy, small in space usage, and capable of being widely applied to the fields such as the facility design optimization, the equipment research and development and the staff training of the nuclear fuel reprocessing plant head end.

Description

technical field [0001] The invention belongs to virtual reality technology, and in particular relates to a virtual reality system and method capable of economically and truly simulating the mechanical operating environment at the head end of a nuclear fuel reprocessing plant. Background technique [0002] The level of radioactivity in the hot chamber at the head end of the nuclear fuel reprocessing plant is very high, and its internal mechanical operations are all remotely operated by power hands, remote control cranes, and manipulators. Thick concrete walls, narrow internal operating space, and hazy observation windows (observation windows are composed of multiple layers of lead glass and filled with oil between the two layers of glass) have brought great difficulties to long-distance operations. Difficult positioning, clamping deviation and other problems occur, and incidents of equipment collision or drop occur from time to time, seriously affecting work efficiency, and e...

Problems solved by technology

However, long-term cold commissioning and structural rectification will consume a lot of manpower and material resources, resulting in excessive energy consumption; operation training often requires the construction of a 1:1 simulated hot cell, to ensure the training effect, it is also necessary to build a complete hot cell scene, Purchasing various mechanical parts for training is economical

[0003] In the fields of nuclear power, ships, and automobiles, virtual reality technology has been used to carry out design verification, employee training, etc., but most of them are roaming display applications, lacking information feedback; in addition, it has been applied in aerospace, medical and other fields The mechanical feedback system realizes human-computer interaction, but this kind of equipment is often single-function and expensive, and there is no qualitative development and progress in recent years, so it is difficult to popularize

The head end of the post-processing involves more than ten kinds of key equipment that require remote operation. The operation control panels and remote control devices are varied and cannot be used universally. If the existing technologies and methods are adopted, the control components need to be created one by one, and a corresponding information feedback system needs to be equipped. The cost of construction will increase significantly, and the space occupied will be huge

Moreover, many key equipment in the head-end facilities of the post-processing project are in the stage of supplementation, improvement and optimization, and the control methods and operation panels are also constantly changing, making it difficult to reuse virtual control hardware facilities
