Method for monitoring box-type object and related apparatus

Abstract

A method for monitoring a box-type object and a related apparatus are provided, for example, a monitoring device (200) or a container. The monitoring device (200) includes: a transmitting module (210), a receiving module (220), and a processing module (230). The transmitting module (210) and the receiving module (220) are located on a to-be-monitored box (130) and/or located in an area that is on a transport device of the box (130) and that is relatively static with the box (130); the transmitting module (210) is configured to transmit a test signal; the receiving module (220) is configured to receive the test signal; and the processing module (230) is configured to: determine a channel characteristic based on an electrical signal corresponding to the test signal, and determine, based on the channel characteristic and an initial channel characteristic, whether a state of the box (130) changes.
