Embodiment Construction

[0029] In order to expand the ultrasonic and infrared signal receiving angle of the ultrasonic ranging or positioning system, the present invention becomes an omnidirectional ultrasonic receiver by improving the traditional directional ultrasonic receiver; meanwhile, an interference ultrasonic absorbing device is also designed / structure; and combine this interference ultrasonic absorbing device / structure with the above-mentioned omnidirectional ultrasonic signal receiver, this compound structure can make us arbitrarily set the receiving range and blocking range of the ultrasonic signal; in order to cooperate with the ultrasonic signal receiving To expand the range, the convex lens is used to expand the infrared receiving angle of the infrared receiving sensor. Through the above several key technical means, an omnidirectional ultrasonic / infrared signal receiver that can receive ultrasonic signals from all directions, effectively block ultrasonic signals from interference direct...

Abstract

The invention discloses a method and a system for expanding a receiving angle and distance of an ultrasonic signal and an infrared signal, and is characterized in that a novel ultrasonic omnidirectional receiver, an interference ultrasonic absorption device / structure and a device which expands the receiving range of the infrared signal by an infrared lens are designed into an ultrasonic and infrared distance measurement or positioning system; and the structural combination of the devices can also be carried out so as to obtain the omnidirectional ultrasonic receiver with large receiving range and effective anti-interference.

Description

technical field [0001] The present invention relates to ultrasonic and infrared ranging or positioning devices, in particular to an acoustic design method and device for improving the angle and distance of ultrasonic signal reception on ultrasonic ranging or positioning devices, and expanding the receiving of infrared signals by using infrared lenses Methods and apparatus for angles and distances. Background technique [0002] Ultrasonic ranging and positioning devices have been widely used, such as in robot vision, especially in electronic whiteboard systems (including copy electronic whiteboards and interactive electronic whiteboards) in recent years. figure 1 shown. [0003] An ultrasonic ranging or positioning system roughly includes two parts: the transmitting part and the receiving part. Ultrasonic ranging / positioning has two modes: [0004] One is an integrated transceiver, such as a reversing radar, which means that the ultrasonic transmitting part and receiving p...
