ULTRASONIC DETECTION DEVICE AND DETECTION METHOD THEREOF

摘要

The present invention is directed to an ultrasonic detection device and detection method thereof. The ultrasonic detection device includes a processor and a transceiver module, whereby the transceiver module may be operated to enter an additional reception mode and receive a first ambient echo. The processor may analyze the first ambient echo and generate an analysis result. When the generated analysis result shows that the first ambient echo has a signal characteristic indicative of an interference source in the environment, the transceiver module may again enter the additional reception mode before a detection operation is performed. As a result, an elimination mode may be performed to correctly obtain or distinguish the corresponding reflected wave of the detection operation, thereby avoiding an error of operation, such as distance detection, due to the presence of an interference source.

1. An ultrasonic detection method applied for an ultrasonic detection device that includes a processor and a transceiver module, the method comprising:
causing the transceiver module to enter an additional reception mode and receive a first ambient echo; analyzing the first ambient echo with the processor and generating an analysis result; and causing the transceiver module to again enter the additional reception mode before performing a detection operation when the analysis result shows that the first ambient echo has a signal characteristic.
