Abstract

The invention provides a method for alarming the loss of outdoor personnel, including: connecting with a terminal device via Bluetooth; detecting the Bluetooth connection status with the terminal device in real time, and sending a pre-alarm when it is detected that the terminal device is in a disconnected state; Reconnect with the terminal device within the preset reconnection time or the first preset reconnection times; if the reconnection is successful within the first preset reconnection time or the first preset reconnection times, stop issuing the pre-alarm and re-enter the detection Otherwise, it is determined that the terminal device is beyond the safe distance and a lost alarm is issued, the location information is obtained, and the location information is sent to the cloud server. Use Bluetooth to bind the central office and terminal equipment. When the connection is interrupted, a pre-alarm will be issued to prevent signal fluctuations. When there is no reconnection within a period of time, it will be judged as lost. It is more reasonable to determine lost and improve the safety of outdoor personnel. In addition, the present invention also provides a method and system for alarming the loss of outdoor personnel.

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...
