Problems solved by technology

[0003] However, these current solutions need to use a camera, and the location of the camera also has high requirements. Because the implementation of the existing solutions is too limited, the scope of application is limited, and they can only be used on specific occasions. Based on image recognition, when the crowd It is also difficult to achieve when it is too dense or there are many obstacles

Abstract

The invention provides an outdoor personnel loss alarm method, which comprises the following steps: carrying out Bluetooth connection with terminal equipment through Bluetooth; detecting a Bluetooth connection state with the terminal equipment in real time, and sending out a pre-alarm when detecting that the Bluetooth connection state is disconnected with the terminal equipment; reconnecting withthe terminal equipment within a first preset reconnection time or a first preset reconnection frequency; if the reconnection succeeds within the first preset reconnection time or the first preset reconnection frequency, stopping sending out the pre-alarm and entering the detection state again; otherwise, judging that the terminal equipment exceeds the safety distance, sending out a lost alarm, acquiring position information, and sending the position information to a cloud server. According to the invention, local side and the terminal equipment are bound in a Bluetooth mode, pre-alarm is conducted to prevent signal fluctuation when connection is interrupted, and it is judged that the terminal equipment is lost only when reconnection is not conducted within a period of time, so that it is judged that the terminal equipment is lost more reasonably, and the safety of outdoor personnel is improved. The invention also provides an outdoor personnel loss alarm method and system.

Description

technical field [0001] The invention relates to the technical field of lost persons, in particular to a method and system for alarming lost persons outdoors. Background technique [0002] The loss of personnel is a very serious problem that has always existed at present. When a person is lost, it is difficult to track and find it, which leads to subsequent serious safety accidents. At present, there are some solutions, such as the use of image recognition, which can monitor specific groups within a certain area in real time, and give an alarm when the mutual distance exceeds the preset range. [0003] However, these current solutions need to use a camera, and the location of the camera also has high requirements. Because the implementation of the existing solutions is too limited, the scope of application is limited, and they can only be used on specific occasions. Based on image recognition, when the crowd It is also difficult to achieve when it is too dense or there are m...
