Abstract

The embodiment of the invention provides a loss prevention method, a loss prevention device and a loss prevention system and relates to the field of wireless signal transmission. The loss prevention method provided by the embodiment of the invention comprises the following steps: acquiring a first signal strength value of a first wireless signal transmitted by a wireless signal receiving and transmitting device by using the loss prevention device; measuring according to the first signal strength value to obtain the distance between the loss prevention device and the wireless signal receiving and transmitting device; judging whether the measured distance is larger than a preset detection distance, and sending an alarming signal if the measured distance is larger than the preset detection distance. By the loss prevention method, the loss prevention device and the loss prevention system provided by the embodiment of the invention, reliable guarantee is provided for preventing loss of a monitored object, and the problem that the existing monitored object is easy to lose can be solved.

Description

technical field [0001] The present invention relates to the technical field of wireless signal transmission, in particular to an anti-lost method, device and system. Background technique [0002] In life, old people (especially those with dementia) or children often get lost, which brings great pain to relatives. Although social security is constantly improving, the phenomenon of property theft still emerges in endlessly. In view of the phenomenon of lost relatives and stolen property, people need to be more meticulous in their lives, and how to more effectively avoid such situations has become an urgent problem to be solved. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide an anti-lost method, device and system to improve the problem that monitored objects (old people, children, property, etc.) are easily lost. [0004] In the first aspect, the embodiment of the present invention also provides an a...
