Disclosed is an infrared ray positioning node device, including a reflection cup with a plurality of side surfaces; and an infrared ray emitting tube cooperating with the reflection cup and being positioned so that the range of an included angle m formed after the rays emitted by the infrared ray emitting tube reflect off some reflection side surfaces in the plurality of side surfaces is 0°≦m180°. Also disclosed is an infrared ray positioning node system. The present invention makes the direction of an infrared ray emission signal controllable in the range of 0°-180°, makes the signal stable and even in intensity, improves the radiation utilization of the infrared ray emitting tube, reduces the power consumption of the node device, realizes uniform projection of infrared light, and effectively avoids emission blind areas of a single node and signal interference between adjacent nodes.
