INFRARED RAY POSITIONING NODE DEVICE AND SYSTEM

摘要

An infrared ray positioning node device and system. The device comprises: a reflective cup (1) having a plurality of side faces; an infrared ray transmitting tube (2) used for coordinating with the reflective cup (1). The infrared ray transmitting tube (2) is positioned so that the range of an included angle m formed after light rays emitted by the infrared ray transmitting tube (2) are reflected by some reflective side faces (11,12) of the plurality of side faces is 0°≤m<180°.By enabling the direction of an infrared ray emission signal to be controllable within the range from 0° to 180° and enabling the signal to be stable and to have a uniform strength, the illumination utilization of an infrared emission tube is improved, the power consumption of the node device is reduced, the uniform projection of infrared rays is realized and the signal interference between an emission dead zone of a single node and an adjacent node is effectively avoided.
