Embodiment 1

[0033] This embodiment provides a method for sending a broadcast message. Before describing the method, first combine figure 1 The lost equipment involved in the method and the broadcasting system composed of the relay equipment are described. figure 1 It shows a possible positional relationship between the lost device X, the relay device A, the relay device B and the receiving device O, wherein, figure 1 The circle around the device in , is used to indicate the coverage of the device signal, based on figure 1 The shown process of retrieving the lost device X by the broadcast system composed of the lost device X, the relay device A, the relay device B and the receiving device O may include: the relay device A receives the broadcast information of the lost device X, forwards it, The relay device B receives the broadcast information forwarded by the relay device A, and then forwards it out. The receiving device O receives the broadcast information forwarded by the relay device ...

Embodiment 2

[0051] This embodiment provides another method for sending a broadcast message, which is implemented by a relay device. The relay device can be used to receive the broadcast message of the lost device and broadcast the received broadcast message to expand the coverage of the lost device. signal coverage, Figure 4 is the flowchart of the method, such as Figure 4 As shown, the method includes:

[0052] Step 401: receiving a broadcast message;

[0053] In step 401, the acquired broadcast signal may be sent by the lost device, in this case, the received broadcast message will include the location information of the lost device.

[0054] Step 402: Perform frequency scanning with a third preset period to determine a third broadcast frequency point;

[0055] Step 403: Broadcast the acquired broadcast signal with the third broadcast frequency.

[0056] In this embodiment, after receiving the broadcast message, the broadcast frequency point can be determined directly, and the rec...

Embodiment 3

[0061] This embodiment provides a device for sending a broadcast message, which is used to implement the method for sending a broadcast message provided in the first embodiment above, Figure 5 is the block diagram of the device, as Figure 5 As shown, the device 50 includes:

[0062] The first determination module 51 is configured to perform frequency scanning in a first preset period to determine the first broadcast frequency point when it is judged that the working state of the device is abnormal;

[0063] An acquisition module 52, configured to acquire the location information of the device;

[0064] The first broadcast module 53 is configured to use the first broadcast frequency to broadcast the location information of the device;

[0065] The second determination module 54 is configured to increase the preset period to the second preset period when the broadcast message containing the device location information is obtained, and perform frequency scanning with the seco...

Abstract

The invention aims to provide a broadcast message sending method, a broadcast message sending device, a storage medium, equipment and a broadcast system, which are used for solving the problem of difficulty in obtaining lost equipment positioning information in related technologies. The broadcast message sending method disclosed by the invention comprises the following steps: under the condition of judging that the working state of equipment is abnormal, carrying out frequency sweeping in a first preset period to determine a first broadcast frequency point; acquiring position information of the equipment; broadcasting the position information of the equipment by using the first broadcast frequency point; under the condition that the broadcast message containing the equipment position information is obtained, increasing a preset period to a second preset period, and performing frequency sweeping in the second preset period to determine a second broadcast frequency point; and when the second preset period arrives, broadcasting the position information of the equipment at the second broadcast frequency point. On the basis of reducing the energy consumption of the lost equipment, the probability of finding the lost equipment is improved.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a broadcast message sending method, device, storage medium, equipment, and broadcast system. Background technique [0002] At present, unmanned aerial vehicles, unmanned vehicles and other equipment often lose control due to equipment failure, interference, collision and other reasons. In order to retrieve the lost device, it is necessary to locate the lost device. However, due to the limitation of the lost device's own positioning function and communication function, if the lost device is far away from the auxiliary device, it is difficult to obtain the location information of the lost device. , it may be necessary to search in a larger range, for example, it may be necessary to temporarily set up a communication network, which consumes a lot of manpower and material resources for searching. Contents of the invention [0003] The purpose of the present di...
