Abstract
An environment detection method includes the following steps is provided. Firstly, an ultrasonic wave is emitted to a first reflecting cone by an ultrasonic transmitter, wherein the ultrasonic wave is reflected to the environment by the first reflecting cone in a full circumferential direction. Then, the ultrasonic waves reflected back from a second reflecting cone is received by an ultrasonic receiver. Then, a received signal waveform received by the ultrasonic receiver is recorded by a controller.
Claims10
An environment detection device, comprising:
- an ultrasonic transmitter configured to emit an ultrasonic wave;
- a first reflecting member having a first reflecting cone, wherein the first reflecting cone is configured to reflect the ultrasonic wave to an environment in a full circumferential direction;
- an ultrasonic receiver;
- a second reflecting member having a second reflecting cone, wherein the second reflecting cone is configured to reflect the ultrasonic wave reflected back from the environment to the ultrasonic receiver;
- and
- a controller electrically connected to the ultrasonic receiver and configured to record a received signal waveform of the ultrasonic wave received by the ultrasonic receiver.
