Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, in a first aspect, in one embodiment, the present invention provides an outdoor people missing alarm method, including:
102, establishing a bluetooth connection with at least one terminal device capable of being matched through bluetooth.
The execution main body in the embodiment is local side equipment, the local side equipment is used in cooperation with terminal equipment, the local side equipment can be worn on a leader of an outdoor operation team, and the terminal equipment can be worn on other team members except the leader. Before outdoor work begins, the equipment can be grouped together, and the equipment codes of the corresponding equipment of corresponding personnel are pulled into the same group and bound. When the user walks to the operation area, the connection can be opened, and the devices corresponding to the personnel in the group can be connected. The output power of the Bluetooth can be adjusted to set the radiation range, and the specific range is set according to actual requirements.
And step 104, detecting the Bluetooth connection state with the terminal equipment in real time, and sending out a pre-alarm when detecting that the Bluetooth connection with the terminal equipment is in a disconnection state.
The local side device is the leading device, detects the Bluetooth connection state of each terminal device in real time, and sends out a pre-alarm when detecting that the corresponding terminal device is disconnected. The alarm mode can be through pilot lamp and bee calling organ, and the preliminary alarm will send as long as being in disconnection, and corresponding terminal equipment probably because barrier shields signal or other interference and causes this moment, consequently only takes the preliminary alarm at the very first time, just carries out the alarm of wandering away after later judgement lost.
Wherein when reporting to the police, can export the wearing person's identity name that disconnected terminal equipment corresponds through the display module to can make things convenient for the wearing person that local side equipment corresponds to know.
And 106, reconnecting with the terminal equipment within the first preset reconnection time or the first preset reconnection times.
Wherein, after disconnection occurs, reconnection is attempted, which is defined by a predetermined time or number of times. For example, if the first predetermined reconnection time is set to 5 seconds, it indicates that reconnection is continuously attempted within 5 seconds after disconnection. For example, if the first reconnection number is set to 10, it means that 10 reconnection attempts will be made consecutively after disconnection. Reconnection in the first preset reconnection time or the first preset reconnection times is to judge whether the wearer corresponding to the terminal equipment is actually lost or not more reasonably, and compared with disconnection, the lost judgment is more practical and has a certain fault-tolerant rate.
If the reconnection succeeds within the first preset reconnection time or the first preset reconnection times, the fact that the wearer corresponding to the terminal equipment is not lost is indicated, the process is finished, and the detection state is continuously kept. If the result is not successful, the information shows that the wearer corresponding to the terminal equipment loses mostly, so that the loss alarm needs to be carried out, and the search and rescue needs to be carried out. Specifically, the position information of the local-side equipment after disconnection is sent to the cloud server, the cloud server can analyze the position information, and the search and rescue team at the rear can arrive in time. Because the radiation range of bluetooth can be set for in advance, consequently know the position confidence of local side equipment back, with this position as the centre of a circle, regard as the radius with the radiation range, just can outwards extend a reasonable distance according to this circle scope and search for and rescue, search for and rescue the success rate very high like this, avoided blindly looking for.
If reconnection occurs in the search and rescue process, the situation that the wearer corresponding to the terminal equipment is out of the lost state and returns to the safe distance is indicated, and at the moment, the alarm is relieved.
The pre-alarm and the missing alarm are realized through corresponding alarm devices, the alarm devices respond to the pre-alarm and the missing alarm in different degrees, the missing alarm is more violent, for example, a honey device, the missing alarm is more urgent and has large volume, and the specific response mode can be set and adjusted according to actual requirements.
According to the method for alarming the loss of the outdoor personnel, the local side and the terminal equipment are bound in a Bluetooth mode, pre-alarming is carried out to prevent signal fluctuation when connection is interrupted, the personnel are judged to be lost when reconnection is not carried out within a period of time, and therefore the personnel can be judged to be lost more reasonably. And when the lost position appears, the position of the local side equipment is also transmitted to the cloud end, and the lost position can be further analyzed through the position information. In addition, through bluetooth, can control safe distance, also need not influenced by the crowd, influenced by the barrier also very little. The safety of personnel, especially outdoor operation personnel is improved.
In one embodiment, the reconnection unsuccessfully within a first preset reconnection time or a first preset reconnection number includes:

In the reconnection process, there may be signal fluctuation to result in accidental successful connection, and if the connection is considered as successful connection and reenters a detection state, it may affect search and rescue timeliness, for example, a wearer corresponding to the terminal device is already at a radiation edge and moves away from the office-side device, and at this time, disconnection occurs, but due to environmental influences and the like, a radiation range of bluetooth is not a fixed value, and floats within a range, and therefore, certain signal fluctuation may occur, and connection to the office-side device may be possible at one moment, but connection at this time is meaningless. The validity of connection is guaranteed by presetting the connection time, so that the loss can be judged more truly. Only after effective connection, disconnection is counted or counted again by the first preset reconnection time or the first preset reconnection times.
In a second aspect, as shown in fig. 2, in one embodiment, the present invention provides an outdoor people missing alarm method, including:
And step 204, detecting the Bluetooth connection state and the connection signal strength of the terminal equipment in real time.
