Multi-heat-source temperature touch representing device

Abstract

The invention discloses a multi-heat-source temperature touch representing device, which comprises a temperature representing array, a heat insulating shell, a heat conducting substrate, a refrigerator, a radiator and a measuring and controlling circuit, wherein the temperature representing array is formed by arranging a plurality of cylindrical electrical heaters in parallel at intervals along the same direction; each cylindrical electrical heater is provided with a hot end temperature sensor; the upper part of the temperature representing array is fixed by the heat insulating shell; the lower end of the temperature representing array is fixed by the top surface of the heat conducting substrate; the refrigerator is provided with a cold end face and a hot end face; the upper end of the refrigerator is provided with a cold surface which is tightly contacted with the bottom surface of the heat conducting substrate; a temperature sensor is arranged between the cold surface and the bottomsurface of the heat conducting substrate; the lower end of the refrigerator is provided with a hot surface which is tightly contacted with the lower radiator; and the measuring and controlling circuit comprises a heating circuit of the temperature representing array, a hot end temperature feedback and control circuit, a refrigerating circuit of the refrigerator and a cold end temperature feedbackand control circuit.

Description

technical field [0001] The invention relates to tactile reproduction in virtual reality technology, in particular to a multi-heat source temperature tactile reproduction device, which can realize near-end reproduction of remote temperature tactile sensation, and belongs to the technical field of testing and control. Background technique [0002] With the widespread application of virtual reality technology and interactive teleoperation robot technology, a large number of tactile reproduction devices are required. The most important features of virtual reality technology are "multi-perception", "interactivity" and "presence", so an ideal virtual reality system should have a good performance in these aspects. So far, research on haptics at home and abroad has mainly focused on force haptics. The application of continuously optimized force haptic algorithms in flexible and textured haptic reproduction devices enables these devices to better reproduce the flexibility and texture...

AI Technical Summary

Problems solved by technology

When multiple heat sources need to be reproduced in the virtual environment or the remote real environment, the temperature tactile reproduction device based on a single heat source cannot reproduce them at the same time, but can only reproduce them separately, but this will seriously affect the performance of the virtual reality system. Real-time, and it is impossible to experience the feeling of touching multiple heat sources at the near end; although the finger-worn multi-heat source temperature tactile reproduction device can enable the operator to experience the feeling of simultaneously touching multiple heat sources, this type of device only Limited to touch sensing with fingertips, palms, arms or other parts cannot conveniently sense and recognize multiple heat sources at the same time
