State the position that the 3rd intercommunicating pore is located between the 1st intercommunicating pore and the 2nd intercommunicating pore.
This utility model provide the classroom interaction device for answering question based on infrared ultrasonic positioning techniques, for be based on infrared excess
The digital pen of sound localization technology is supported the use, you can realize handwriting information acquisition function.Specifically, with reference to Fig. 2, in writing paper
Classroom interaction device for answering question is put in top, when student is write or drawn on writing paper using digital pen, can pass through triggers circuit
Drive installation is worked simultaneously in the sonotrode and infrared transmitter of digital pen, and therefore, sonotrode is to all around
Launch ultrasound wave, meanwhile, infrared transmitter is to all around launching infrared light.As the spread speed of infrared light is far longer than
Ultrasonic propagation velocity, therefore, infrared sensing circuit collects infrared signal first, also, from digital pen transmitting infrared light to
It is very of short duration that infrared sensing circuit collects infrared signal elapsed time, negligible；When infrared sensing circuit is gathered
During to infrared signal, now engrave as T1, data processor the 1st ultrasound wave receiving circuit of driving and the 2nd ultrasound wave receiving circuit
Work, the 1st ultrasound wave receiving circuit receive the moment of ultrasound wave and are designated as T2, and the 2nd ultrasound wave receiving circuit receives ultrasound wave
Moment be designated as T3, referring to Fig. 2,1 represents the 1st ultrasound wave receiving circuit；2 represent the 2nd ultrasound wave receiving circuit, 3 represent infrared
Sensing circuit；4 pen tip positions for representing digital pen；Therefore, by the calculating of ultrasonic transmission time and ultrasonic transmission speed,
It is L1 that nib is obtained to the distance between the 1st ultrasound wave receiving circuit, the distance between nib to the 2nd ultrasound wave receiving circuit
For L2, but due to the distance between the 1st ultrasound wave receiving circuit to the 2nd ultrasound wave receiving circuit be given value, so, can position
