MONITORING DEVICE

摘要

A monitoring device comprising a plurality of emitters and a plurality of receivers is provided. The emitters are capable of being driven to emit waves with directivity. The receivers are correspondingly disposed with respect to the emitters for receiving the waves. The transmitting paths of the waves define a monitoring area. The monitoring device is able to determine the moving trend and the location of the first object in the monitoring area when the specific waves are reflected to and received by the corresponding receivers.

1. A monitoring device for monitoring a first object, comprising:
M emitters, wherein M is a positive integer, and the emitters are capable of being driven to emit waves with directivity; and N receivers, wherein N is a positive integer, and the receivers are disposed corresponding to the emitters and each used for receiving the wave emitted from the corresponding one of the emitters; wherein transmitting paths of the waves define a monitoring area, and when the waves are reflected by the first object within the monitoring area and received by the corresponding receivers, a moving trend of the first object with respect to the monitoring area is determined by a quantity change of the receivers receiving the reflected waves.
